Educational Program on Tobacco Abuse and Addiction Essay

Tobacco is a farming produce that is used for smoking through the form of a cigarette. It normally contains nicotine as well as harmane. Tobacco causes so many diseases such as cancer, cardiovascular and lung diseases. Generally tobacco is smoked, sucked, chewed and snuffed. They contain a very high addictive psychoactive ingredient called nicotine. Tobacco is even worse compared to other drugs. Nicotine is also a very addictive substance clearly known by man and it is very strong and acts very fast. Nicotine is a drug which has many different effects within the body and it stimulates one’s system, even if it makes one feel more relaxed. Nicotine also affects the chemicals in the brain and immediately after the puff one begins to feel high for a second and that is the reason why so many smokers look at smoking as stress relief since they are under pressure. Nevertheless, the program is designed purposely to motivate and educate teenagers and young adults between ages 23-30 the major effects one experiences after tobacco abuse. The program will address the effects of tobacco abuse and it is aimed at increasing the adult’s knowledge of the major effects of tobacco use. The adults between 23 years and 30 years will experience so many activities that will permit them to keep away from using tobacco. During the presentation, all the aforementioned adults will be able to know the effects of nicotine and alcohol cancer being one of them. On the other hand, nicotine tends to cause short-term chances of high blood pressure, heart rate, as well as the flow of the blood right from the heart. Carbon monoxide reduces the amount of oxygen that the blood carries. The long term effects of smoking causes persistent lung disease, coronary heart disease, and stroke, with cancer of the larynx, lungs, mouth, esophagus and bladder. It goes ahead and forms cancer, cervix and the kidneys. The educational program is going to address all this effects of tobacco such that all the adults will be aware and stop taking tobacco.

US Economy

The Jan aura release of the most current GAP became available showing that the fourth quarter GAP was 4. 1 . While with recent government regulation they lowered the first quarter GAP to 2. 5 percent. However, following the report will include a statement about my personal prediction for the remainder of the 2014 fiscal year using sets of very complex variables and skilled opinions. Unemployment Rating: The unemployment rate in the United States as anticipated by the IIS Federal Bureau of Economic Analysis is around 6. 7 percent as of the beginning of the 2014 in February as demonstrated on the graph pictured above.This number s estimated using the numbers given for persons in the United States that have been actively looking for job opportunities as a percentage of the labor force. This number has been gradually decreasing since July 201 2 and will continue to decline as the job market continues to expand with new technologies and education. Although, during the holiday seasons the unemployment always goes down, but as soon as they end, such as after Christmas and thanksgiving the number increases by almost 2 percent. The number of federal employees in 201 2 decreased to almost 22 million jobs which is . Percent less than the year before. Due to the fact that these numbers are only compiled every five years, this . 5 percent decrease is quite shocking to many people. These employees include policemen, nurses, and teachers along with many more. While the number of unemployment among the youth continues to increase, the percentage of adult men and women without health insurance will also continue to rise with the execution of Obama care. Unemployment Rate February 2014 Month/Month Year/Year National 6. 7% +0. 1 Florida 6. 2% 0. -17 As shown in the chart above, the unemployment rate of Florida is demonstrated versus the rest of the United States. Governor of Florida, Rick Scott announced that Florist's statewide unemployment rate for May 2013 dropped to 7. 1 perc ent, the lowest rate since September 2008. Florist's rate was down O. 1 percentage point from Aprils rate of 7. 2 percent and continues to fall below the national average, which went up to 7. 6 percent in May. As Florida continue to distance itself from the national unemployment rate it is clear that the state government will succeed in growing opportunities for Florida families.Due to the incredible successes that Florida communities had experienced, Florist's unemployment rate is well below the national average. Gross Domestic product (GAP)I The gross domestic product (GAP) measures of national income and output for a given country's economy. The gross domestic product (GAP) is equal to the total expenditures for all final goods and services produced within the country in a stipulated period often. The Gross Domestic Product (GAP) in the Lignite States was worth 15684. 80 billion US dollars in 2012. The GAP value of the United States represents 25. 30 percent of the world economy. GAP in the United States is reported by the The World Bank Group. From 1960 until 201 2, the united states GAP averaged 5725. 9 USED Billion reaching n all time high of 1 5684. 8 USED Billion in December of 2012 and a record low of 520. 5 USED Billion in December of 1960. At the beginning of the first quarter of 2014 the GAP was 2. 4 percent due to the recent government sanctions to promote businesses and services locally instead of internationally. Although, the US Federal Bureau of Economic Analysis states that the United States represents 25. 30 percent of the world's economy.The increase in real GAP in 201 3 primarily reflected positive contributions from personal consumption expenditures (PACE), exports, residential fixed investment, nonresidential fixed investment, and private inventory investment that were partly offset by a negative contribution from federal government spending The deceleration in real GAP growth in 201 3 primarily reflected a deceleration in nonresidential fixed investment, a larger decrease in federal government spending, and decelerations in PACE and in exports that were partly offset by a deceleration in imports and a smaller decrease in state and local government spending.

Raymond Carver Essay Example | Topics and Well Written Essays - 1500 words

Raymond Carver - Essay Example When the family moved to California, Carver became interested in writing and took a course from John Gardner, which had a profound effect on him. He continued his studies at Chico State University, Humboldt State College, and the University of Iowa. He earned a BA in 1963. He became a textbook editor at Science Research Associates, Palo Alto, but was fired in 1970. He went on to teach at universities throughout the United States and from 1980-1983 was a professor of English at Syracuse University. While Carver was at Humboldt, he wrote his first story, "Pastoral," as well as his first poem, "The Brass Ring." Although his biography states he started his writing career as a poet, he confessed he was never a "born" poet (Liukkonen) and although he eventually had his poetry published, it never received the acclaim of his short stories. His story "Will You Please Be Quiet, Please" was written in 1967 and with the editing expertise of Gordon Lish, he published a collection of stories of the same name set in Eureka, California in 1976 (Boddy). During the ensuing years, alcohol was a problem for him and drinking became a full-time pursuit. In fact, alcohol became a subject in several of his stories. On June 2, 1977, Carver stopped drinking and became active in Alcoholics Anonymous. He begin seeing poet Tess Gallagher and divorced his wife MaryAnn in 1982. He lived with Gallagher and married her two months before he died from lung cancer in 1988 (Liukkonen). Carver has said that everything we write is, in some way, autobiographical. In a New York Times article he said he considered the short story a vehicle for transforming the commonplace and said, "it is possible to write a line of seemingly innocuous dialogue and have it send a chill along the reader's spine" (Carver par. 9). His writing style is muted and anticlimactic but creates a tense atmosphere. His life is basically divided into two sections, one before he gave up drinking and met Tess and one after. "Cathedral," a short story contained in a collection by the same name, gives him the chance to write in retrospect, utilizing his life experiences in the first section of his life as part of his writing within the second part of his life. His father's alcoholism possibly led to Carver's addiction to alcohol since an addictive personality can be and often is passed down. "Cathedral" was published in 1983, after Carver had joined AA, but the characters in the story spend a great dea l of time in intervals of drinking and smoking marijuana. There are three characters in the story-the narrator, his wife, and a blind man. The narrator, who would appear to be based on Carver himself, distances himself from the story by being an observer rather than a participant-at least at first. As the story progresses, he unobtrusively fixes himself drinks, and although it is never evident or brought out, the excess drinking throughout the story labels him as an alcoholic, albeit a recovering alcoholic.. He refers to his wife's friend as "this blind man," and it is clear he is dismissing any personal interest in the man's forthcoming visit. "I wasn't enthusiastic about his visit. He was no one I knew" (Carver "Cathedral" 1). Even so, he offers the reader background on the

Strategy Tripod Assignment Example | Topics and Well Written Essays - 1750 words

Strategy Tripod - Assignment Example 72). When it comes to global business, strategy is perceived in two dynamics, 1- strategy as action, and 2) strategy tripod. The ‘strategy as action’ perspective suggests that the essence of strategy is interaction because actions and reactions such as ‘competing aggressively’, ‘price war’, ‘attack’, ‘counterattacks’ etc lead to competitive advantage (Peng and Gokalp, 2011, p. 250). The ‘strategy tripod’ model sheds light on global competitive dynamic based on the major three perspectives, namely industry-based, resource-based and institution-based views. The Strategy Tripod The fundamental objective of the competitive strategy of a company is to gain sustainable competitive advantage in the industry. There has been a great amount of academic debates during recent years concerning competitive strategies to explain ‘why do firms succeed and often fail’. There are different approaches concerning competitive strategy such as SWOT, Porter’s five force etc. The strategy tripod is another approach to explain competitive strategy that states that a company’s competitive strategy derives from three main sources: the pressure of the industry the company operates in, the impact of the institutions that a company is surrounded by and the resources that a company possesses (Wallner, 2012, p. 12- 13). Peng (2008, p.14) identified the very fundamental four questions in strategy. They are: 1) ‘why do firms differ’? 2) ‘How do firms behave’? 3) ‘What are the main determinants of the scope of a firms’? 4) What are the main determinants of a firm’s success or failure? He elucidated the concept of ‘strategy tripod’ to answer ‘how do firms behave’. According to him, strategy tripod is a framework that states that a competitive strategy as a discipline has three ‘legs’, that are the basic three perspectives; industry-based, resource-based and institution-based views of a firm. Three leading strategy perspectives, namely industry-based view, institution-based view and resource-based view of the firm collectively lead to a strategy tripod. The industry-based view highlights the five-forces affecting an industry and explains that the strategic effort is meant to examine the five competitive forces namely competitive rivalry, threat of entry, threat of substitutes, bargaining power of suppliers and bargaining power of customers. The resource-based view concentrates on strengths and weaknesses internal to a firm, whereas the industry-based view focuses on the opportunities and threats that are external to a firm. Industry-based view thus concentrates on the O and T whereas the resource-based view concentrates on the S and W in the SWOT (Peng, 2008, p. 14). The institution-based view suggests that a firm and its competitive strategy conditions are influenced by the institutions that the firm is surrounded by. The three ‘legs’ of strategy tripod are explained in detail below: Industry-based view The industry-based view, which is pioneered by Michel Porter in early years of 1980s, emphasized that the primary principle of competitive strategy formulation is the relationship that a firm builds with its environment. External factors are the major determinants of a firm’s competitive strategy because these factors not only affect firm’s performance but also its way to achieving competitive advantage (Gao, Murray and Kotabe, 2010). Firms are largely depending on various external industry forces such as threats of substitutes and new entrants, bargaining power of buyers and suppliers and competition rivalry among the major counterparts.

The Challenges of Living in a Foreign Land and Speaking New Language Essay

The Challenges of Living in a Foreign Land and Speaking New Language - Essay Example I can still remember vividly the moment when the aeroplane I travelled in taken off from the airport. As the plane took off, I had mixed feelings of curiosity and anxiety; I was curious because I was looking forward to beginning my adventure in America, and, on the other hand, I was anxious because of the challenge of living in a new culture and speaking a foreign language; the feeling of anxiety made me feel like jumping off the plane and going back home. When the flight attendant came round with some cold beverages, I was in deep emotions and felt like crying, but I forced myself to smile so as to create the impression that I was okay. I asked the flight attendant to give me a Coca-Cola drink because Coca-Cola was the only name of cold beverage that I knew in English. The freight attendant seemed quite friendly and upon giving me the Coca-Cola drink she started talking to me in English, but, unfortunately, I did not understand what she was saying to me. This incident made me start imagining how it would be difficult to live in America without being able to communicate in English well. When we arrived in America and my consultant left me in the dorm, I felt so anxious and hopeless. For the first two days in America, I wasn’t feeling so bad, but after the two days, I was overcome with homesickness and I started crying. Homesickness made me feel completely heart-broken. Some of my colleagues, the students, tried to console me and to reassure me that all will be well, but all their efforts to console me were fruitless.

Defining Beauty Essay Example | Topics and Well Written Essays - 1500 words

Defining Beauty - Essay Example While beauty might have once been truly ‘in the eye of the beholder’, today’s society has beauty defined for it by the overwhelming challenges of the mass media. These messages of the media are so consistent they overwhelm any natural sense of beauty, which is important to our sense of identity and social value. Throughout the history of mankind, humans have projected who and what they are, including their relative social position, through their outward appearance. Study after study has demonstrated people dress a certain way and strive to acquire specific items as a means of signifying that they belong to a particular desirable subset of individuals who also embody their individual ideals (Gilman, 1999). Regardless of whether one has always been a part of this subset or not, it is presumed that an outer appearance in keeping with this group will automatically purchase the coveted membership. In the past few centuries, however, the standard definition for female beauty has had detrimental effects on the feminine identity. â€Å"Women view their bodies as ‘objects of work’ requiring attention and upkeep in order to operate well and promote the desired effect† (Gillen, 2001). ... â€Å"Research in the UK suggests that the wealthier we are, the more likely we are to dislike our body. Experts think there’s more pressure on the wealthy to achieve the thin 'ideal' because they have the money to do so and are more exposed to media images† (Rebecca, 2006). Because the wealthy are expected to be able to achieve this ideal, those who are not so wealthy often struggle to attain the beauty ideal as a means of signifying that they belong within the ranks of the wealthy. Within the past few years, televisions have been inundated with so-called ‘make-over’ shows in which the focus is precisely for the media to inform the public regarding what is considered beautiful or desirable. These shows promise an improved exterior facade to participants’ bodies, fashion sense, faces, homes, lifestyles, etc. that will bring the individual into closer similarity to the ideal image and thus make it possible for them to achieve a higher level of happine ss. This ‘ideal’ image is usually envisioned as someone in their mid-20s, slender almost to the point of skeletal, with specific body measurements at the bust and hips and a specific ‘good-looking’ charm that usually includes blonde hair and a friendly demeanor. This limited view of the ideal obviously eliminates anyone who might have been born with larger bones or other ‘defects’ that resist the reshaping of the plastic surgeon’s scalpel from being accepted into the socially acceptable. Makeovers on TV illustrate the unacceptable qualities of the average individual and emphasize the importance of bringing the individual image more in line with a perceived social ideal that is communicated through the same media channel. It is thus perceived that the only way for individuals to find

Select a recent research journal article that presents the results of Literature review

Select a recent research journal article that presents the results of empirical research in an area that you are interested in - Literature review Example The paper â€Å"Cultural Values and International Differences in Business Ethics† by Scholtens and Dam provides a limited and preliminary analysis of the ethical policies of industries in different countries in relation to the cultural differences prevailing between countries. The analysis, covering around 2700 firms in 24 countries, suggests significant country specific variations in ethical policies. As for the dependence of country culture in the shaping of ethical policies, some pattern does seem to emerge. The analysis indicates that the cultural dimensions of individualism and uncertainty avoidance tend to impact a firm’s ethical policies positively. Masculinity and power distance on the other hand, seem to have a negative effect on the shaping of ethical policies (pp.273, 276). The research questions are, firstly, whether there are any significant differences in the ethical policies between industries belonging to different countries, and secondly, how the ethical policies are related to typical cultural values in a country. The underlying reasons for some countries consistently outperforming many other countries all over the world may be inherent in their cultures. This analysis is aimed at exploring the existence of such associations and the extent of their impact. The analysis does not use any questionnaire but uses other sources which have compiled data using questionnaire and survey techniques. It builds on the findings of Langlois and Schlegelmilch (1990), Hood and Logsdon (2002), Kaptein (2004), and Singh et al. (2005). The analysis also uses Hofstede’s (1980,1991) dimensions of culture. The authors feel that this paper may be the first to do quantitative analysis of the relationship between culture and business ethics (Scholtens and Dam, p.279). Data gathered on the basis of questionnaire and survey of firms in various areas by Ethical Investment Research Service (EIRIS) is used to derive data on

Eve, the Heroine Essay Example for Free

Eve, the Heroine Essay Milton’s Paradise lost, Eve is the heroine. She is most often overlooked as a heroic figure because she is not a central character, and her character does not demonstrate equality in comparison to Adam or Satan. A hero or heroine is someone who demonstrates heroic qualities such as courage, leadership and independence. Heroism requires self sacrifice for the greater good of all humanity and excellent morals. In order to argue Eve as a heroine I will investigate Eve’s heroic qualities, the imperfection of Eden and Satan versus Eve. Eve shows independence when she suggests to Adam to split up in the garden in order to finish their assigned tasks faster. She states, â€Å"let us divide our labors; thou, where choice† (Milton, IX. 214). This is the first time when Eve guides Adam instead of following him. Eve assures Adam she is capable when she convinces him that separating in the garden is a better solution. Eve is intelligent and relies on her ability to reason (Milton, IX. 654). Adam believes that Eve has knowledge of good and evil and trusts her to go alone in the garden. (Milton, IX. 697) Eve is the first person to disobey God, by eating the forbidden fruit from the tree of knowledge. This demonstrates leadership and courage. Eve is aware of the retribution following the rebellion of god’s commands. After having sinned and feeling remorseful, Eve proposes to take her own life. This act of selflessness shows how heroic in nature she is. God offers Messiah to partake in Adam and Eve’s punishment. God takes their immortality by turning them into humans instead of killing Adam and Eve (Paradise Lost). The two mortals are able to repent for their sins. Eve’s rebellion against God is treated as heroic because the fall is fortunate. Her actions ultimately pave the way for humankind’s redemption and salvation, the deliverance from sin. The punishment of expelling Adam and Eve from the Garden of Eden revolutionized Paradise. They went from being virginal beings, the purest of forms, into fallen sinful humankinds. Milton, who was a Protestant, believed that Jesus sacrificed his life in exchange for others to repent their sin. Many Christians believed that the fall corrupted the entire world, forcing people of future generations to commit original sin. Original sinners would then turn to God because they could not attain an everlasting life. Eve, the first of humankind to sin, passes the original sin down to all her descendants. This caused the notion that it is in humankind’s nature for future human beings to sin and ask forgiveness of all sins. Augustine, who studied theology, said, â€Å"God judged it better to bring good out of evil, than to suffer no evil to exist† (Oulter). Augustine promoted the concept of original sin. He stated that God has good reason for evil to exist, even though he did not create it. Evil cannot exist unless God willed it; therefore he can use it for his glory and for our good (Oulter). According to Augustine and Milton, the fall was a fortunate fall because the Garden of Eden is not perfect. The fall is ultimately good sprouting from an evil action. Without the fall from Eve and Adam, humankind would not have freedom of will or be able to make mistakes. Eve is the heroine because she is the first human being in the Garden of Eden to disobey God, creating change in Paradise Lost and in the end creates Felix culpa, which is a Latin word for â€Å"fortunate fall†. Eve and Satan have a lot of similar characteristics for example, they are both leaders, demonstrate braveness, disobey God, and envy others with higher power and authority. However, Eve’s rebellion differs from Satan’s primarily because Eve and Adam show remorse and shame after they have sinned. They seek God’s forgiveness by deciding to ask forgiveness for their sins, instead of taking Satan’s path of constant rebel without repentance. They understand that God will eventually forgive them over time and their sins can be corrected through generations of hard labour on Earth. This is a true sacrificial gesture and can be seen as very heroic in nature. Eve is also selfless when she abstains from procreation. She is worried that her sinful nature will be passed on to her future children and they will be judged. Eve admits that it will be hard yet adds that Adam and she have the power to control their own destiny. Satan in contrast to Eve is very selfish. He is so envious of God’s power that he tries to overcome heaven. Satan thrives for the power and glory of his almighty. He disobeys God once again by going to the Garden of Eden and convinces Eve to eat from the tree of knowledge. Satan receives his punishment and does not regret any of his actions. Satan does not believe in God’s creations and denies his priority by stating that the angels were self-raised (Milton,V. 860). Satan speaks his mind when he says that nobody remembers their birth. This is a huge difference compared to Eve’s belief in God. Satan has a lot of power yet he continues to seek more. In comparison, Eve searches for equality. Milton’s demonstration of Eve wanting to be equal when Eve considers not telling Adam what she has done, â€Å"In Femal Sex, the more to draw his love, and render me more equal, and perhaps, a thing not undesireable, sometime superior for inferior who is free?† (Milton, IX. 822- 825). She thrives for equality with Adam so she can be taken seriously while engaging in intellectual conversations with Raphael. Eve demonstrates all the qualities a hero would possess such as: courage, bravery, independence, leadership and intellectual ability. She changed Paradise forever. Without the fall, Eden’s imperfection would have remained and the world would be different today. Satan though powerful, did not show remorse or regret for his sins and for this reason he is not a hero. Because of Eve’s actions and decisions she is the ultimate heroine of Paradise Lost.

Cells Breaks the Tor’s Anonymity: Onion Router

Cells Breaks the Tor’s Anonymity: Onion Router Ms. S.SIVARANJANI Ms. R.BACKIYALAKSHMI B.E, M.Tech., Abstract To hide the communication of users, the anonymity systems pack the application data into equal – sized cells. The size of IP packets in the Tor network can be very dynamic and the IP layer may be repack cells. A new cell-counting attack against Tor allows the attacker to confirm anonymous communication relationship among users very quickly. By varying the number of cells in the target traffic at the malicious exit onion router, the attacker can embed a secrete signal into variation of cell counter of the target traffic and it will be carried and arrive at the malicious entry onion router. Then an accomplice of the attacker will detect the signal based on received cells and confirm the communication among the users. There are several features of this attack. First, it is highly efficient and confirms very short communication session with only tens of cells. Second, this attack is effective and detection rate approaches 100% with a very low false positive rate. Third, it is possible to implement the attack in a way that appears to be very difficult for honest participants to detect. Keywords Anonymity, cell counting, mix networks, signal, Tor. INTRODUCTION Anonymity has become a necessary and legitimate aim in many applications. Here the encryption alone cannot maintain the anonymity required by users. Generally speaking, mix techniques can be used for either message-based or flow-based anonymity applications. Research on flow-based anonymity applications has recently received great attention in order to preserve anonymity in low-latency applications, including Web browsing and peer-to-peer file sharing. To degrade the anonymity service provided by anonymous communication systems, traffic analysis attacks have been used. The Existing traffic analysis attacks can be categorized into two types: passive traffic analysis and active watermarking techniques. The active watermarking technique has recently received much attention to improve the accuracy of attack. In this technique is to actively introduce special signals into the sender’s outbound traffic with the intention of recognizing the embedded signal at the receiver’s inbound traffic. The core contribution of the paper is a new cell counting based attack against Tor network. This attack confirms anonymous communication relationship among users accurately and quickly and it is difficult to detect. The attacker at the exit onion router detects the data transmitted to a destination and then determines whether the data is relay cell or control cell in Tor. After excluding control cells, manipulate the number of relay cells in the circuit queue and flushes out all cells in the circuit queue. This way the attacker can embed a signal into the variation of cell count during a short period in the target traffic. To recover the embedded signal, the attacker at the entry onion router detects and excludes the control cells, record the number of relay cells in the circuit queue and recover the embedded signal. The main features of cell-counting based attack are: (1) This attack is highly efficient and can quickly confirm very short anonymous communication sessions with tens of cells. (2) It is effective and detection rate approaches 100 % with very low false positive rate. (3) It makes difficult for others to detect the presence of the embedded signal. The Time – hopping based signal embedding technique makes the attack even harder to detect. SYSTEM ARCHITECURE There are two types of cells: Control cell and Relay cell. The CELL_CREATE or CELL_CREATED used for setting up a new circuit. CELL_DESTROY used for releasing a circuit. Relay cell is used to carry TCP stream data from client to bob. Some of the relay commands are: RELAY_COMMAND_BEGIN, RELAY_COMMAND_END, RELAY_COMMAND_ DATA, RELAY_COMMAND_SENDME, and RELAY_ COMMAND_DROP. The Onion router (OR) maintains the TLS connection to other OR. Onion proxy (OP) uses source routing and chooses several ORs from cached directory. OP establishes circuit across the Tor network and negotiates a symmetric key with each OR, one hop at a time, as well as handle TCP stream from client application. The OR on other side of circuit connects to the requested destination and relay the data. The OP will sets up TLS connection with OR1 using protocol, through this connection , OP sends CELL_CREATE cell and uses Diffie-Hellman (DH) handshake protocol to negotiate a base key k1=gxy with OR1. Form this key; a forward symmetric key kf1 and backward key kb1 are produced. This way first hop circuit C1 is created. Similarly OP extends the circuit to second and third hop. After circuit is setup, OP sends a RELAY_COMMAND_BEGIN cell to the exit onion router and cell is encrypted as {{{Begin}kf3}kf2}kf1. While the cell traverses through circuit each time the layer of onion skin are removed one by one. At last the OR3 last skin is removed by decryption then it open a TCP stream to a port at the destination IP, which belongs to bob. The OR3 sets up a TCP connection with bob and sends a RELAY_COMMAND_CONNECTED cell back to Alice’s OP. Then the client can download the file. PROCESSING CELL AT ONION ROUTER The TCP data is received by OR from port A and it is processed by TCP and TLS protocols. Then the processed data is delivered to the TLS buffer. The read event is called to read and process the data pending in the TLS buffer. This read event will pull the data from TLS buffer into the input buffer. Then the read event process cells from input buffer one by one. Each OR has routing table which maintains map from source connection and circuit ID to destination connection and circuit ID. The transmission direction of the cell can be determined by the read event. To append the cell to the destination circuit the corresponding symmetric key is used to decrypt / encrypt the payload of the cell, replace the present circuit ID with destination circuit ID. The cell can be written directly for the destination connection if there is no data waiting in output buffer and the write event is added to the event queue. After calling the write event, the data is flushed to TLS buffer of destination. Then write event pull as many cells as possible from circuit to output buffer and add write event to event queue. The next write event carry on flushing data to output buffer and pull cells to output buffer else the cell queued in circuit queue can be delivered to network via port B by calling write event twice. Fig. 2Processing the cells at Onion router CELL – COUNTING BASED ATTACK The IP packets in Tor network is very dynamic and based on this the cell – counting based attack implemented. Dynamic IP packets over Tor : The application data will be packed into equal sized cells (512-B). While the packets transmitted over the Tor network it is dynamic. Because of this reason the size of packets from sender to receiver is random over time and large numbers of packets have varied in sizes. The main reason for this is the varied performance of OR cause cells not to be promptly processed and also if network is congested, cells will not delivered on time, because of this the cell will merge and non-MTU(Maximum Transmission Unit) sized packets will show up. Work-flow of Cell – Counting based attack: Step 1: SELECTING THE TARGET :- The attacker log the information at the exit OR, including the server host IP address and port for a circuit and circuit ID and uses CELL – RELAY-DATA to transmit the data stream. Step 2: ENCODING THE SIGNAL :- Until the write event is called the CELL – RELAY – DATA will be waited in the circuit queue. After the write event is called then the cells are flushed into output buffer. Hence the attacker can manipulate the number of cells flushed to the output buffer all together. This way the attacker can able to embed the secret signal. To encode bit 1, the attacker can flushes three cells from circuit queue and for bit 0, flushes one cell from circuit queue. Step 3: RECORDING PACKETS :- After the signal is embedded in the target traffic it will be transmitted to the entry OR along with target traffic. The attacker at the entry OR will record the received cells and related information and need to determine whether the received cells are CELL – RELAY – DATA cells. Step 4: RECOGNIZING THE EMBEDDED SIGNAL :- The attacker enters the phase of recognizing the embedded signal with the recorded cells. For this used the recovery mechanisms. Once the original signal is identified the attacker can link the communication between Alice and Bob. There are two critical issues related to attack: (1) Encoding signals at exit OR: Two cells are not enough to encode â€Å"1† bit. Because if the attacker uses two cells to encode bit â€Å"1† then it will be easily distorted over network and also hard to recover. When the two cells arrive at the input buffer at the middle OR, the first cell will be pulled into circuit queue and then if the output buffer is empty, the first cell will be flushed into it. Then the second cell will be pulled to the circuit queue. Since the output buffer is not empty, the second cell stays in the circuit queue. When the write event is called, the first cell will be delivered to the network, while the second cell written to the output buffer and wait for the next write event. Consequently, two originally combined cells will be split into two separate cells at the middle router. So the attacker at the entry OR will observe two separate cells arriving at the circuit queue. This cells will be d ecoded as two â€Å"0† bits, leading the attacker to a wrong detection of the signal. To deal with this issue the attacker should choose at least three cells for carrying bit â€Å"1†. For transmitting cells, proper delay interval should be selected: If the delay interval among the cells is too large, users are not able to tolerate the slow traffic and to transmit the data will choose another circuit. When this condition happens the attack will fail. And if the delay interval is too small, then it will increase the chance that cells may combined at middle OR. (2) Decoding signals at the entry OR: Distortion of signal: Anyway the combination and division of the cells will happen due to unpredictable network delay and congestion. This will cause the embedded signal to be distorted and the probability of recognizing the embedded signal will be reduced. Because of this distortion of the signal, a recovery mechanism can be used, that recognize the embedded signal. The combination and division of cell can be categorized into four types: (1) Two types of the cell division for the unit of the signal and (2) Two types of the cell combination for different units of signal. To deal with these types of division and combination types of the cells the recovery algorithm can be used. If the number of cells recorded in the circuit queue is smaller than the number of the original signal are recovered as either two types of cell division for the unit of the signal. Suppose the number of cells recorded in the circuit queue is larger than the number of cells for carrying the signal; the recovered signal will be either two of the cell combination for different units of signal. When the signals are recovered in these types with k ≠¤ 2, can consider that these signals are successfully identified otherwise cannot be identified. Attack Delectability: To improve the attack invisibility can adopt the time-hopping-based signal embedding technique, which can reduce the probability of interception and recognition. The principle of this technique is, there exit random intervals between signal bits. At the exit OR, the duration of those intervals are varied according to a pseudorandom control code which is known to only the attackers. To recover this signal, the attacker at the entry OR can use the same secret control code to position the signal bits and recover the whole signal. If the interval between the bits is large enough, the inserted signal bits appear sparse within the target traffic and it is difficult to determine whether groups of cells are caused by network dynamics or intention. Therefore the secret signal embedded into the target traffic is no different than the noise. And when a malicious entry node has confirmed the communication relationship, it can separate the group of cells by adding delay betw een the cells so that not even the client can observe the embedded signal. In this paper a signal is embedded into the target traffic, which implies a secrete sequence of groups of one and three cells. With the time-hopping technique, groups of one and three cells are separated by random intervals and it is hard to differentiate them from those caused by network dynamics and since the embedded signal is very short and only known to attacker, can conclude that it is very difficult to distinguish traffic with embedded signals from normal traffic based on this very short secret sequence of cell groups. CONCLUSION AND FUTURE WORK In this paper, we presented a cell-counting based attack against Tor network. This can confirm the anonymous communication among the user quickly and accurately and it is very difficult to detect. The attacker at the exit OR manipulates the transmission of cells from the target TCP stream and embeds a secret signal into the cell counter variation of the TCP stream. Then the attacker at the entry OR recognizes the embedded signal using developed recovery algorithms and links the communication relationship among the users. In this attack the detection rate is monotonously increasing function with the delay interval and decreasing function of the variance of one way transmission delay along a circuit. This attack could drastically and quickly degrade the anonymity service that Tor provides. Due to the fundamental design of the Tor network, defending against this attack remains a very challenging task that we will investigate in future work. REFERENCES [1] W. Yu, X. Fu, S. Graham, D.

Project management example: The London Eye Project management example: The London Eye Introduction Generally, the definitions of project management have diversities, but in commonly project management is used to accomplish business ambition, strategies and well-defined work tasks within a certain schedule and limit budget (Sabin, 2006). The project management required skill, experience, processes, methods and knowledge in order to complete the objectives of the project (Association for Project Management, 2014). Most strategists succeed in these days with high competitive and fusing global economy are mostly using the project management techniques to deliver substantial quality of business results within limited time and budget (Project Management Institute, 2014). Jamieson Morris (2004) support that project management is a key factor in business process. Even in many definitions of project management, the fundamental is about attaining the jobs done. The London Eye is the huge project that was designed by architectures David Marks and Julia Barfield, its purpose to represent modern architectural design and engineering of the first of the millennium century (Tim and Ian, 2000). The London eye was the tallest Ferris wheel in the world by height 135 meters, after success, with Star of Nanchang in 2006, Singapore Flyer in 2008 and High Roller in 2014 in order. The construction of London Eye used 16 months to finish in order to celebrated of the year 2000, London Eye also knows as the Millennium Wheel. In the first year of operation, number of visitors approximately was 3.2 millions, hence this becomes more popular of attracting visitors in the United Kingdom. The production cost of the London Eye is 75 million pounds and took 50 percent of time less than normal to finish the project (Marks Barfield, 2014). This makes London Eye is one of the most interested project to measure and examined in the process of project management. A project must have three variables that can estimate certain time of the project, limited by budget and meet quality requirement (Lester, 2007). Characteristics in process of construction London Eye can be evaluated as the project, because of the constrains from budget and time, no repetition of construction, requirement of a variety of skill and experience expertise involve. From all of these characteristics summarize that the London Eye is classified as a project. The scope of this paper study is to investigate two aspects, which are stakeholders management, project planning and scheduling that make London Eye become a successful project. However, it is essentially that we have to understand the background of the project first, in order to understand the process. London Eye’s Characteristics Since 2000, the London Eye has become one of the iconic landmarks of London. The concept of London Eyes was introduced in 1993 by the architecture name Marks Barfield. His design of Ferris wheel submitted to the Architecture Foundation competition in order to build to celebrate the millennium year. In 1994, British Airways interest to become a sponsor of the project. In 1996, the permission of the project was successfully made by the agreement of shareholders as the result, Tussauds Group was joined as the last partner. The London Eye was constructed before the year 2000 only 16 months (The British Broadcasting Corporation, 2005). More that 5 different oversea companies worked to build London Eyes and it took 7 years till it was open. The formal opening ceremony on 31, December 1991 and follow by public open on 9, March 2000. The Iron Triangle Figure1: Iron triangle of London Eye project The Iron Triangle is the traditional technique for evaluating project performance, which have three variables; time, cost and scope that try to balance each others (Atkinson, 1999; Gardiner and Stewart, 2000). If one of the three variables is changed, it will affect one of the others too. For example; if stakeholders want less time of construction, they need to increase the budget or reduce the scope (Gregory, 2006). In (Figure1) shows The Iron Triangle of London Eye project follow by time, cost and scope. The London Eye used only 16 months in order to finish the construction process, in order to celebrate millennium century, that is 50 percent less than normal process. The cost of construction of London Eye was 75 million pounds higher than average cost of normal construction. But the cost of building was not issued to be a problem because the main purpose of this is to open on time and to be the biggest Ferris wheel in the world (London Eye, 2014). To understand the key elements of project management, such as stakeholders management, project planning and scheduling which are the factors to push the London Eye finished on time. The Author will illustrate and explain two of variables in further. Stakeholders Management According to, Freeman and Reed (1983) has given a definition of stakeholder is someone that â€Å"can affect the achievement of an organizations objectives or is affected by the achievement of an organization’s objectives†. Bourne and Walker (2004) suggest that even a project manager was able to deliver the project with the original scope, cost and time, but without the attention of stockholders, a project might probably not be able to success. The conflict in stakeholders must be managed, because it might lead to projects fail (Bourne and Walker, 2005). A stakeholder can be any individual, institution or organization that involves the interaction with the project or business. The stakeholder might effect from project, both direct and indirect, and can be occasional or ordinary contact with the project (Paul, 2013). Identify who are the stakeholders and understand the role of them must be done. London Eye project have many stakeholders who are investing in the project. But the key stakeholders of the project, who have the potential to support and facilitate the project can clearly identify. David Marks and Julia Barfield, who invented the idea of the wheel in 1990 were a press campaign to support the concept. Bob Ayling, Chief Executive of British Airway in that period offered financial and corporate support to this project. In 1997, Tussauds Group was brought into the position of the operator. The London Eye Company Limited, were owned by three owner separate in equal shard. David Marks and Julia Barfield owned one third, The Tussauds Group also owned one third and lastly one third owned by British Airways, who was the leading support during the development phase. Government didn’t support the project, except the construction of new pier, in purpose to protect collision of the wheel. For financing purpose of the London Eye project was provided by Sumitomo Bank and Westdeutsche Landesbank (Tim and Ian, 2000). Mace is the UK’s leading company on the project management, as appointed to be Project Managers in 1998. Seven groups of contractors were chosen to project, they were responsible for building and design as follows: Tilbury Douglas Construction Ltd for Foundations, Civil works and Pier structure, Hollandia BV for Wheel Structure, Pomagalski SA for Capsules and Controls, T Clarke PLC for Electrical Installations, Littlehampton Welding Limited for Boarding Platform and Pier Finishes, Waterers Landscape PLC for Landscaping and Alandale Construction Limited for County Hall Fit-Out (Tim and Ian, 2000). From this we can identify stakeholder as two types; internal stakeholders and external stakeholders. Internal stakeholder can be people who involve in part of the business for example; shareholders, managers and employees. External stakeholders are the people who outside the business such as customers, local community, suppliers, press and government (The British Broadcasting Corporation, 2014). Figure2: Stakeholders Web and Internal External Stakeholder From the figure2 above, researcher attempt to explain the understanding of the internal and external stakeholders of The London Eye by using The Stakeholder Web describe. From internal stakeholders, Shareholders can be British Airways, David Marks Julia Barfield and Tussaudes Group that interested in dividends and growth of shares. Managers and employees are interested in salaries and job security. From external stakeholders, suppliers concerned in delivering services and finished project on time. Government, Tourists, Londoner and also including people around the South Bank area are impacted from the project such as the project might effects to new businesses that can take benefits from London Eye such as bars and restaurants. Traffic around the London Eye maybe influenced because increasing of tourists. All of these influencers can become stakeholders of the project. Stakeholders have different of interests, to manage this conflict it’s necessary to understand the types of stakeholders and what can influence their behavior. By classifying the different groups of stakeholders, using stakeholder power and interest matrix, to organize based on the level of power and interest. Stakeholder classification of power and interest matrix map will make groups of stakeholders easier to understand. Stakeholders can be classified in two big dimensions, of power and interest (Newcombe, 2003; Johnson and Scholes, 1993). The basic concept is who have high power and high interest will be the key players and also need to manage it. Figure3: London Eye stakeholder power and interest matrix From the figure 3 shows that London Eye project stakeholders were classified by level of interest and power. The key players in this case can be British Airway who is supporting the financial and able to control the project. Bank and financial institutions such as Sumitomo Bank and Westdeutsche Landesbank, that provided financial loan. Press and local community didn’t have power, but the project directly effects to their living or career. Same as the government, they didn’t provide the financial support but able to collect taxes from the project. Customers and Londoner can be in the group of minimal effort. The success of The London Eye project definitely involved with the stakeholder management. The well understanding in position and its roll are significant to make this project completed. However, it is not only stakeholder management, variable that leads to the success of the project. Many factors that involved included planning and scheduling of the project also are the important variables. Project Planning and Scheduling Project management planning is one of the important variables that required lists of time, quality and cost. Project management planning depends on types and sizes of project (Lester, 2007). The role of project management can separate into three main areas; 1) It can handle the operational requirement to meet the customer satisfaction, 2) The project must be completed on time and 3) Control and delivery the job on the previous set of constrains budget. Good project planning will lead to success according to these three goals. For more understanding of London Eye planning, researchers will apply Work Breakdown Structure (WBS) is the technique for controlling and planning project. Secondly Gantt chart technique will also use to explain in this project. The Work Breakdown Structure (WBS) To organize the structure of the project, Work Breaking Structure assists the work process. It is similar to the outline of the book or report. WBS is the brief version of work structure that help to perform and focus on plan, track and evaluate of the project (Gregory, 2006). According to the diagram, it consists of three benefits of using WBS, First, WBS are easier to evaluate the cost and time of work. Second, it is easy to break down the work into the small tasks and makes it easier to measure the progress. Third, it eases the separation of the tasks into the team member. Moreover, WBS contains two kinds of tasks: the summary tasks and the work packages. Summer tasks will describe each of the processes in the project, for the work packages describe as the lowest level task that required details to complete. From the figure4 shows The London Eye’s Work Breakdown Structure. WBS identifies the work that should be done, based on researcher’s understanding and assuming. The summary tasks can be divided up to four main tasks; safety, stakeholders (internal and external), physical and organizational. Moreover there are more subordinate level breakdown into each main tasks. For example, in physical tasks and the construction of wheel, capsules and foundation can be described as the lower level task of each level. The Gantt chart The Gantt chart was developed during the World War I invented by Henry Laurence Gantt. The Gantt chart uses to identify the necessary steps to obtain a result of work. The process of doing Gantt chart is worked by projecting schedule, follow step by step, from the final result, analyst activities, timing of process and sequence of tasks (Gregory, 2006). The chart can used to compare the estimated time of the project before, start with initial time on the actual time that really spent. Furthermore, Gantt chart can apply to every project, both in big project and small project. For example, building a factory, making a cup of glass or producing a musical. Figure5: London Eye’s Gantt chart From the figure5 shows The London Eye’s Gantt chart. The researcher is using information from the previous research and available documents to create this Gantt chart (The British Broadcasting Corporation, 2005; Tim and Ian, 2000). From this chart can see that London Eye project used approximately 7 years of planning, finding sponsors, get permits and construction. The London Eye can be estimated as the long project in-term of planning, but comparing to the time on construction is apparently very short compared to this kind of the project. Conclusion of the project The London Eye is one of the most successful projects in many aspects. It’s also one of the most successful in architect design of 21st century. The components of London Eye must be assembled above The Thames River that required high technology to handle the project. The original plan of London Eye was planned to be completed the construction in 2 years, but in, finally it used only 16 months to finish the project. If according to, The Iron Triangle theory said that if one of the three variables was changed, it will affect one of the others too. London was used the budget around 75 million pounds to build, but the project’s time construction is faster than expected and the scope has not changed. Unfortunately, components of London Eyes have to ship up and assemble in the Thames River this made it harder to deliver projects on time (Tim and Ian, 2000). The London Eye is not the ordinary project for both suppliers and project management team. To be able to finish on deadline, all around the prost have to be given to everyone who was a part in this project. Shareholders and investors of the project must spend huge money in order to justify risk of the project. For example, if poor quality and not finished on time happened, this implies that the cost of the project may not be the first priority of concern. Therefore, the time and scope or quality must be the first and second priority of the scope in the project. Mace construction that was controlling the project management team of London Eye should be accredited for the achievement and deliver project before deadline. But if they can decrease time for searching operators and suppliers, it could save the cost of the production because time of construction can reduce cost of production. From the stakeholder management perspectives, it illustrates the conflict of interest in shareholders, as the factor of â€Å"Time† had become a conflict among them. However, British Airway as a big shareholder that support financial fund during the construction had burden the high cost of production and risk. But in terms of marketing, British Airway can promote and impose the branding under the sponsorship deal. British Airway also improves brand image by using London Eye as the presenter of their brand. Recommendation of the project Researcher found that from this paper, it helps to understand theories and concept of project management, which make it easier to manage and deal with the project. The fundamentals of controlling cost, deliver on time and satisfaction in quality are significantly important. Not only the stakeholder management and project planning and scheduling will lead to the success of the project. But risk management, uncertainty management, resource management, scope management and other management aspects should be concerned as part of the success factors in project management. Other aspects of business should be considered as important as project management such as financial, human resource management and costumer relationship management. The London Eye project was won over 25 awards for engineering tourism, innovation and design including; 2003 Queen’s Award for Enterprise Innovation Furthermore, the project can make huge profits from the first few months of opening and had recovered the cost (London Eye, 2014). From this show that minimize cost is not always important for business but deliver customer expectation and requirement sometime is more important. The main problem of this project is about lack of managing for future that effects to cost which increases more that it should be. The project manager should concern this point because when one varies in cost, time and quality of project, it will always affect one the others as a whole. 1

Conditions for the Haber Process

Conditions for the Haber Process In this essay I will find out what are the best conditions for the production of the maximum yield in the Haber process, by running simulations of the Haber process at different conditions to determine the best conditions. From the Experiment I found that the lowest temperature possible and the highest pressure possible would provide the best conditions to operate the Haber process at for the maximum yield possible. Introduction The Haber process is an important Process used in chemical Industry to manufacture Ammonia from Nitrogen and Hydrogen that originate in the air. The reason why its very important is it turns an inert gas Nitrogen (N2) and a very volatile and reactive gas Hydrogen (H2) into ammonia which is a stable compound but reactive enough to be used in different aspects. Why was the Haber process discovered? During the First World War Britain Cut off Germany Supply route to Chiles salt peter natural deposits. Since the Allies (Russian Empire,  United Kingdom,  France,  Canada,  Australia,  Italy, the  Empire of Japan,  Portugal  and the  United States) has gained control over the natural deposits of saltpetre from natural deposits found in Chile, therefore cutting off Germanys access to materials that the needed to produce necessary items such as food, guns, bombs other war materials.   Germany has to find ways to produce its own hence the Haber process which was discovered in 1909 by a German chemist named Fritz Haber to produce ammonia was set into industrial scale in 1913; the produced ammonia was later processed into a Synthetic Form of Chile saltpetre Introduction The Haber process is the process that uses extracted nitrogen from the atmosphere and reacts the nitrogen (N2) gas would react with 3 moles of hydrogen (H2) gas by using a medium temperature around 473K-673K (200- 400 °C) High atmospheric pressures such as 250 atmospheres (25331250 Pascal) and a catalyst to create ammonia (NH3). Due to advancements made to technology we are able to do reaction at extremely high temperatures such as 2300K (2026 °C) and we know that a reaction occurs faster when conducted at the highest temperature possible but the Haber processs success is not calculated on the speed of the reaction but on the yield of the ammonia that is produced during the reaction. Although increasing the temperate would surly increase the rate of reaction in a normal forward reaction the problem with using this method on the Haber process is its not a normal forward reaction type of reaction but is an equilibrium type of reaction. The Chateliers Principle states increasing the temperature will cause the equilibrium position to shift to the left side of the reaction resulting in a lower yield of ammonia because the forward reaction is exothermic. N2(g) nitrogen + 3H2(g) hydrogen Very High heat, Low pressure, catalyst 2NH3(g) ammonia Reducing the temperature will cause the equilibrium system to change the point of equilibrium to minimise the effect of the change, and hence it will produce more heat due to an increase the exothermic reaction therefore causing the wanted increase in the yield of ammonia. N2(g) nitrogen + 3H2(g) hydrogen Low heat, High pressure, catalyst 2NH3(g) ammonia However, the rate of the reaction at very lower temperatures is exceptionally slow, and so a higher temperature should be used to increase the speed of the reaction which results in a lower yield of ammonia but a temperature low enough to create more ammonia than use in the reverse reaction hence we have the final equation is an which an above normal ammonia production. N2(g) nitrogen + 3H2(g) hydrogen High Temperature, Low pressure, catalyst http://www.avogadro.co.uk/chemeqm/eqm_sign.gif   2NH3(g) ammonia Increasing the pressure condition of the haber chamber causes the equilibrium position to shift to the right resulting in an increased yield of ammonia because ammonia has more gas molecules (more moles) on the left hand side or the forward reaction of the equation (4 in total 3 Hydrogen and 1 Nitrogen) than there are on the right hand side or backwards reaction of the equation (2 in total 2NH3). N2(g) nitrogen + 3H2(g) hydrogen High Temperature, Low pressure, catalyst 2NH3(g) ammonia Increasing the pressure means the system will have to adjust to reduce the effect of the change, which is reducing the pressure built up by reducing the amount of moles that can be located in the equilibrium reaction. Uses as ammonia One of nitrogens upper most important uses is in making ammonia (NH3), which is a colourless gas with a strong odour, similar to the smell of urine because urine contain some most definitely contains ammonia. The production of ammonia changes the non oxidation properties of nitrogen as the Oxidation reaction. Pharmaceuticals Used in the manufacture of drugs such as sulphonamide which inhibit the growth and multiplication of bacteria buy the removal of replacing the aminobenzoic acid for the synthesis of folic acids and minerals as well as vitamins and thiamine. Fertilizer An important usage of ammonia is in the making of fertilizers. Ammonia can be used directly as fertilizer by adding it to irrigation water because plants need a good supply of nitrogen in order to grow and which ammonia is able to provide. It is also used to produce the urea (NH2CONH2), which is also used as a fertilizer. Another important use of ammonia is to create nitric acid (HNO3), which is then also used to make fertilizer. The Haber Process didnt lonely provide the Germans with Saltpetre but revolutionized the agriculture industry with an increased yield in crop production enabling them to continue. Cleaning Products Many people use household ammonia as a disinfectant. Nitric acid-made form ammonia-is used in explosives. Ammonia is also used in the plastic industry and as a feed supplement for livestock. The dipole moment of this compound and this is consistent with its geometry, a triangular pyramid due to its electronic arrangement obeying the octet rule, Four pairs of electrons three bonding pairs and one lone pair repel each other giving the molecule the triangular pyramid shape of bond angles of 107 degrees is close to the tetrahedral angle of 109.5 degrees. The electronic arrangement of the valence electrons in nitrogen is described as sp3 hybridization of atomic orbitals. The NH3 molecules and their ability to make hyrodgen bonds explains thir polarity and high solubility of ammonia in water. A chemical reaction occurs when ammonia dissolues in water as it acts as a base acquiring a hydrogen ion from H2O to ammonium and hydroxides ions NH3(aq) + H2O(l) http://www.avogadro.co.uk/chemeqm/eqm_sign.gif NH4+(aq) + OH-(aq) The production of hydroxide ions when ammonia dissolves in water gives the solution of ammonia its alkaline characteristics (basic properties), The double arrow in the equation states that an equilibrium has been reached between the dissolved ammonia gas and ammonium ions The ammonium ion acts as a weak acid aqueous solution because it dissociates to form Hydrogen ion and ammonia. (Shakhashiri, 2008) This is why dissolved ammonia is used in cleaning products because its able to react with both and acid stain and alkaline stain meaning its an all round cleaning products even though the acid is weak its strong enough to deal with domestic stains. Explosives Sodium Nitrate is a Chemical compound with the chemical compound of NaNo3 has been referred to as Chile saltpetre before. And is produced by a reaction of a metal and an acid to produce a salt and is highly soluble in water. (Quote) Sodium Nitrate can be used as a fertilizer and as a material from the production of explosive gunpowder. Naturally gun powder is a rapid burning compound made of Carbon (C12) potassium nitrate, KNO3 and Sulfur and is used in guns because of its capacity to burn in a rapidly producing enough pressure to propel a bullet and not explode. (Quote) Sodium nitrate has antimicrobial properties when used as a food preservative. It can be used in the production of nitric acid by combining it with sulfuric acid. It can used as a substitute oxidizer used in fireworks as a replacement for potassium nitrate commonly found in gun powder. Because sodium nitrate can be used as a Phase Change Material it may be used for heat transfer in solar power plants. Imporantance of Nitrogen Nitrogen gas (N2) is often used as a substitution for air which is a mixture of 78% nitrogen 78%), Oxygen 20%, and 1% of other gases such as Water Vapour Argon and Carbon dioxide (0.03%). where oxidation is unwanted. One area for use is to maintain the freshness to food products by packaging them in nitrogen gas to reduce the fermenting of food due to its properties for preventing oxidization which can cause Rancid unpleasant odour or taste of decomposing oils or fats (http://www.school-for-champions.com/chemistry/nitrogen_uses.htm). Argon has been used as replacement for air in light bulbs to prevent the heated tungsten filament from reacting with the oxygen found in air because Argon is an inert gas but is expensive so ammonia can be reverted back to Nitrogen gas by the process gentrification to replace Argon in light bulbs and is cheaper inert material than Argon. Nitrogen is also used as a controlled storage and Transportation measure food packages due to its capacities to be used as a noble gas, to extend the shelf life of fruits and vegetables and is now used during storage to displace most of the oxygen in the containers http://www.igs-global.com/nitroswing/hdlg.htm, for the purpose of slowing down the reparation and deterioration of food as proven in biochemistry as in aerobic respiration 32 ATP molecules are created from one glucose molecules and 2 ATP molecules are created from one glucose molecule which is a clear sign that respiration and deterioration of food occurs at 16 times slower during anaerobic respiration which respiration without the presence of oxygen, than respiration occurring aerobically which is respiration with oxygen present. Investigation Design To do this Investigation I will be using a simulator that allow we to change the conditions of the Haber process chamber and notice the change in the yield and work out the direction that the equiliburm will take with extra options such as catalysis. Firstly I had to decide what the 2 variables I would be looking at during this investigation and decided that the dependant variable will be the yield of ammonia that I would receive from running the simulations. The Controlled variable will be the temperature and atmospheric pressure that the reaction will be taking place. Another variable that I looked at was if the reaction will be taking place in the presence of a catalyst of not. It was decide that due to the lack of acquiring two or more simulations that were able to run the haber process reaction in the presence of a catalyst The uncontrolled variable would be required in this reaction because the aim of the reaction is to achieve a dynamic equilibrium which is a reaction in which the forward reaction and backward reaction are equal in a closed environment. Meaning all variables and atoms present are controlled and accounted for. Set both simulations at the same pressure and temperature to and begin the reaction recorded both results and create a table of results and find the mean of both tables. Redo the experiment changing the controlled variables every time and recording the yield of the reaction at those conditions Create a Graph using both the mean table to display the results that where shown in the table. This Is the haber process taking place without the presence of an iron catalyst at the temperature of 300oC and 191 atmospheric pressure. Which will give me the amount of ammonia produced in grams and will be working out in percentage of the nitrogen used to allow compatibility of the 2 different simulations that one will be using. Is the Haber process taking place without the presence of an iron catalyst at the temperature that the Chateliers Principle indicates will be the most effective in the promotion of increasing the Yield. Because this Simulation cannot give the yield of the Haber process ammonia moles or grams I have to change the data received from the first simulation into compatible data. Results From these results obtained in the diagram above we notice an increase in yield as we increase the pressure of the reaction while keeping the temperature the same which agrees with the information placed in the beginning of the introduction which states icreasing the pressure will cause the equilibrium position to shift to the right side of the reaction resulting in an increased yield of ammonia since there are more gas molecules Simulation 2 (changing the Pressure but keeping the Temperature at 150) From these results obtained in the diagram above we notice an increase in yield as we increase the pressure of the reaction while keeping the temperature the same which agrees with the information placed in the beginning of the introduction which states the Chateliers Principle states increasing the temperature will cause the equilibrium position to shift to the left side of the reaction resulting in a lower yield of ammonia because the forward reaction is exothermic. And the 0.8 ( r) shows that there is a high positive correlation between the yield amount The Curve tends to show that if the pressure was increased any more that 1000 the increment in the production of ammonia may not be justified for the amount of effort that will be put into creating a haber process camber at that atmospheric pressure. The equilibrium expression for this reaction is: Keq = [NH3]2 [N2][H2]3 Temperature (oC) Keq 25 6.4 x 102 200 4.4 x 10-1 300 4.3 x 10-3 400 1.6 x 10-4 500 1.5 x 10-5 As the temperature of increases, the equilibrium constant decreases as the yield of the ammonia decreases. http://nawabi.de/chemical/ammonia.asp The results of the Ka test agree with the graphs that simulation 1 and simulation 2 provided. As the Ka increases the PH reduces towards the more acidic range meaning the NH3 concentration increases meaning for the best yield of the Haber process, industry must obtain the highest level Ka. Conclusion In conclusion the from the graphs and from the working out of the Keqi can state that the best conditions to process the haber process under is the lowest temperature that is usable because it increases the yield of the haber process in a linear regression which is a positive feedback increase in the yield of ammonia the optimized temperate was 200oC because it provided the highest yield. The other condition that was optimized during this experiment was pressure and after the experiment I found that the highest possible pressure is the optimum condition for this reaction to take place under. Because it gave the highest yield of ammonia compared to lower pressures which all provided lower yield. Evaluation The simulations that were used during this Essay were accurate enough to accept as possible theoretical yield but did not take into account of the possibility that some materials would be lost during the preparation for the haber process. It would have been better if I had more simulations and different type of simulations to check if the results I received from using these simulations were accurate or not and would increase the reliability of this experiment. The limitations to using this method were the some simulations couldnt operate a catalyst which limited the amount of results I was able to obtain and didnt factor in any cost effectiveness into the reaction. The haber process occurring in the presence of a catalysis does not affect the amount of NH3 that is produced by the reaction yet it only hastens the reaction by lowing the activation energy is takes for atoms to react. This would increase the rate of reaction without taking into consideration the geometric position that theses atoms need to react. A catalyst is a chemical that is used in a chemical reaction to speed up the rate of reaction with out the compound being used up in the reaction itself, meaning after the reaction the catalyst retains its structure and physical properties it had before the reaction took place. It works by lowering the activation energy of the reaction. The iron catalyst acts as a platform on which the Nitrogen and hydrogen atoms will bind on to before under going the reaction. The binding on to the catalyst is creates a transactional compound N2(g) nitrogen + 3H2(g) hydrogen Fe http://www.avogadro.co.uk/chemeqm/eqm_sign.gif   2NH3(g) ammonia Another Factor that I should have researched was the rate of reaction and possibly to the cost effectiveness of having a lower rate of reaction over the time effectiveness of having a high rate or reactions. Looking at the effect that the rate or reaction would have on at equilibrium And working out possible ways to reduce the forward reaction to increase the yield of ammonia by adding a rate determining step for the forward reaction to encourage the forward reaction to reaction and produce ammonia but would discourage the backward reaction from according either by adding third party molecule such Sulphuric acid to create ammonium sulphate and can easily to separated by heating to 235oC because it sublimes to create ammonia and sulphuric acid and the gases are at different weights meaning using a gases filtration method and condense then separately. (NH4)2SO4(s) NH3(g) + H2SO4(g) http://image.tutorvista.com/content/equilibrium/reversible-reaction-equilibrium-state.gif Another improvement would be to calculate the H of the reaction while looking at G and S of the reaction to allow to choose the most accurate best conditions for the reaction and most accurate cost effective option for the reaction. Because the having a positive H means the need more energy placed in which reduces the cost effectiveness of the reaction but may increase the yield of the ammonia while the G which measure reactions ability to reaction at room temperature which would increase the rate of reaction and the low temperature would mean the equilibrium would shift and allow the ammonia to be created in much more yield making the reaction cost effective and maximum conditions for the maximum yield. By working out the S and H I could use them to work out the amount of unused heat which is lost to the surroundings during the reaction, after this work out which reaction conditions provide the less heat lost to the surrounding while still providing an acceptable amount of yield. Af ter working out the H, G and S if would help me make a more informed decision on which of the reaction conditions provided current industry yield and cost and work out which conditions provided either current industry yield at a lower cost or improved yield at a higher cost and ultimately work out which conditions produced greatest yield and at the lost possible cost. Another improved for this experiment would be increasing the range of pressure that was used during the simulations because I noticed in the graphs that increasing the pressure post 1000 would make the production of ammonia not as effective as lower pressures are.

Legal Development of Abortion Essay -- Argumentative Persuasive Topics

Legal Development of Abortion      Ã‚  Ã‚   This essay traces the development of abortion law in English and American society up to the time of Roe v. Wade in 1973. Beginning with Biblical citations, the essay researches the Early Church Fathers on the issue; the American colonies; developments of the 1800's which caused change, and so on.    Up to the time of the Protestant Reformation, the English society inherited its traditional anti-abortion law from the Church practice of 1500 years standing; which belief began even before Christianity as part of the Old Testament Jewish belief. The Old Testament tells us: "Death was not God's doing, he takes no pleasure in the extinction of the living" (Wis. 1:13). What is willed is life, and in the visible universe everything has been made for man, who is the image of God and the world's crowning glory (Gen. 1:26-28). In the Christian tradition, the Early Church Fathers taught in The Didache, perhaps the first Christian catechism from 70-90AD, the following in chapter 2, verses 1-2: "The second commandment of the teaching: You shall not murder. You shall not commit adultery. You shall not seduce boys. You shall not commit fornication. You shall not steal. You shall not practice magic. You shall not use potions. You shall not procure [an] abortion, nor destroy a newborn child." (Ju rgens vol.1,p.2)    The colonies inherited English Common Law and largely operated under it until well into the 19th century.

Royal Mail Privatization

According to the Business News on ‘BBC’ which was updated on 8 October 2013, the government intended in privatizing Royal Mail as this had been planned for many years. Royal Mail employees have been given 10% of the shares as part of a stock market flotation. Business Secretary Vince Cable described it as â€Å"the biggest employee share scheme for almost 30 years†. Meanwhile, the public have been given the opportunity to apply to buy shares online until 8 October.An amount of 750 pounds will be the minimum investment for public while the minimum investment for those Royal Mail employees who wished to buy additional shares is 500 pounds. However, an additional 15% of the government’s stake will be sold if the demand for the shares is very high in what is called an ‘over-allotment’ option. â€Å"The company needs access to private capital in order to grow and compete. † said the government and Royal Mail management.Parcel delivery from in ternet shopping is far more important to Royal Mail’s business compared to the delivery of letters, which is shrinking. Furthermore, in order to try to cut public from spending and borrowing more money, the government has been reluctant to invest large sums of money at a time. Moreover, Royal Mail has also been facing competition from private operators such as ‘TNT’ and ‘UK Mail’. Post Office will not be affected in the privatization because it is now a separate company from Royal Mail.The government said that they want to invest more money in the Post Office network as they want to prevent branch closures and eventually set it up as a mutual business. In conclusion, the reason I have chose this particular topic is because Royal Mail is one the most popular and fast delivery postal service Company in the United Kingdom and I personally agree in Royal Mail being privatized as it is giving them a chance to grow and compete in business.

Compare and contrast the Characters of Professor Moriaty Essay

This essay is to show the contrast between two of the villains out of the Sherlock Holmes short stories, Professor Moriarty and Dr Roylott. I will talk about the differences and the similarities between the two villains and how the behave toward Holmes. Dr Roylott is a character from â€Å"The Speckled Band† where he killed his daughter by use of a poisonous snake. Professor Moriarty is a character from â€Å"The Final Problem†. By using the text of these books I am also able to identify and show Conan Doyle’s methods of characterisation. The appearance is one of the primary aspects of a character because without imagery you cannot print a picture of the character in your head of what the character would look like. The appearances of the two villains are very different in build and facial and body features. Dr Roylott is a very large person, as it states in The speckled band, where Roylott meets Sherlock at Baker Street. â€Å"So tall was he that his hat actually brushed the cross-bar.† This shows that Dr Roylott was a man of great height. It also states after that quote â€Å"and his breadth seamed to span across it† This other quote about his build explains that not only was he tall but had a very large chest, and was very bold in his stature. This advantage of size was used to intimidate Sherlock by confronting him. The sheer size difference was used to Roylotts full advantage. Roylotts face is described as being wrinkled and weathered, â€Å"A large face, seared with a thousand wrinkles.† This describes Roylott being quite old or as a man who has been quick to temper and he suffers with a vast amount of stress. It also shows that Dr Roylott is a man who doesn’t act like most people in his class status and is slightly adventurous and hard working. Conan Doyle use of â€Å"a thousand wrinkled† in an exaggerated from and gives more meaning to in that he seamed to have that numerous wrinkles which is able to paint a more accurate image of Roylott in the audiences head. Roylott is also described as a man of agriculture even though he is a man of anger and impulsive rage. â€Å"a peculiar mixture of the professional and of the agricultural.† This explains his professional abilities have bought him wealth and agriculture because of his intelligence. Being wealthy he dresses like a man of his status, in stereotypical dress-code and is s aid as wearing â€Å"a black top-hat, a long frockcoat, and a pair of high gaiters.† Professor Moriarty is quite the contrary where he is nowhere near as large or bold as Dr Roylott. Moriarty is said to be more of a lean build â€Å"He is extremely tall and thin.† Moriarty is quite a tedious man in comparison of the body structure of the two villains but it doesn’t make any difference in Professor Moriarty’s intellectual abilities, and Moriarty does not need a physical advantage. Moriarty is also described as having a large forehead that curves out. This is in relation to his vast superior intelligence to most people, and Doyle used that imagery to try and make the audience see Moriarty as having a large brain that his head has to curve to allow space for it. Moriarty is also described in The final problem as â€Å"He is clean-shaven, pale, and ascetic looking.† For Conan Doyle to say that Moriarty is â€Å"ascetic† he is able to instantly make the audience think that he is a cruel man, but not adventurous. With Moriarty’s intellectual capabilities Doyle is able to make the audience think that he is not committing crimes, but organising them. It also says that Moriarty has a lot of self-discipline for himself. The manner of the two characters is very different. Dr Roylott is a more aggressive man, whereas Professor Moriarty is a more rational man, and talks about something rather that acts like a violent boisterous person. Dr Roylott shows his extreme impatience and violent tendencies when he met Sherlock and Dr Watson, in Sherlock’s home. Roylott storms into where Sherlock is and began to shout at Sherlock about his daughter had been there earlier. Instead of sitting down like Moriarty he confronts Holmes in an aggressive manner and uses intimidation to try and get Holmes to tell him what he wants. Sherlock is not threatened by the show of anger and retains his rationality. In this Roylott realises that he is not going to intimidate Holmes and demonstrates his strength by bending a fire poker to show his power, and leaves with a threat, still trying to intimidate Holmes but also proving a point, he means business. Unaffected by this Holmes carries on with the investigation. Moriarty is the complete opposite in physical aggression, for he isn’t as bulky as Roylott, but in the same way Moriarty attempts to intimidate Holmes, not by a physical show of strength but by a complex and articulate array of words. When Moriarty visits Holmes he insults Sherlock not long after he arrives, â€Å"you have less frontal development than I expected.† This is an insult where Moriarty is trying to say that Holmes is not intelligent enough to out perform Moriarty, in the sense that he will not be able to accuse him without evidence that Holmes will not acquire. This is an entirely alternate method in contrast to Roylott. Moriarty is calm, collective and does not proceed to violence and speaks in a relaxed manor that everything is satisfactory. Moriarty does not need to try and intimidate Sherlock because everything he says carries a lot of weight and he knows that Holmes has met an equally matched adversary, himself.

Nigeria Oil Crisis Essay

Fariha Ahsan, period 5 This article displays a vivid picture for us about the conditions in Nigeria due to the oil reserves. Though Nigeria contained the potential to strive and become a wealthy oil nation, leaving the cocoon of poverty encompassing Africa- it became trapped in a lot of corrupt dealings. Today, the Niger Delta in Nigeria has caught the attention of world wide humanitarian and environmental activists. The article states how in the past, the corrupt government ruling Nigeria was funded by Western governments and large oil corporations. Together, the group have benefited from the fossil fuels that are in abundant supply in the delta region. However, the mines are not the only things that are in this area, there are people of the Niger Delta who have been harshly affected for decades due to this illegal mining. The Ogoni, Ijaw and other minority groups of the Niger Delta have been stripped away of their environment and basic human rights. Their non-violent protests have been ignored and harshly cracked down by the money-hungry government. For example, during one non violent protest, Shell paid several community members to break off the protesting group. The Human Rights Watch has sided with the people of the delta, as it is clearly visible how the oil mining has ruined the area. The oil corporations have destroyed the chances of neighboring communities and minorities to form. Money to control the environmental pollution has been insufficient, causing extremely- harsh living condition with scarce drinking water, and abundance of malnourishment and disease. The oil mining has destroyed the land of the Nigerian Delta as well as the homes of many living there. After the delta started receiving world wide attention some change has begun to start, but the previous government has left behind much chaos. It is reported that in the last decade, the military took control of the region’s people, burned homes and killed masses of civilians. The present government has attempted on being more democratic and open, so change is still underway.
