Nucleosynthesis Essays - Nuclear Physics, Nuclear Chemistry

Nucleosynthesis Essays - Nuclear Physics, Nuclear Chemistry Nucleosynthesis The big bang which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The factories which make these elements are stars. Nucleosynthesis or the synthesis of nuclei, is the process by which stars (which start out consisting mostly of H and He) produce all other elements. The key is nuclear fusion, in which small nuclei are joined together to form a larger nucleus. (This contrasts with nuclear fission, in which a large nucleus breaks apart to form two smaller nuclei). Fusion requires an extremely large amount of energy (see fig. 1), and can typically only take place in the centers of stars. FIGURE 1 a) Low energy proton is strongly repelled by the 7Be nucleus.b) High energy proton moves so fast that it can strike the 7Be nucleus. Once the proton touches the nucleus, it has a chance to stick. If the proton sticks, the 7Be becomes a 8B nucleus.c) 8B is radioactive and changes into 8Be plus a positron (b+) and a neutrino (n). 8Be is itself radioactive, and almost immediately breaks into two 4He nuclei. Protons repel each other. This repulsion becomes stronger as the protons get closer together (just like when you try to stick two magnets together north to north, or south to south. Try this! As you push the magnets closer together, it becomes harder to do). However, if the protons can actually touch each other, they have a chance to stick together! This is because of the strong nuclear force which attracts nucleons (protons or neutrons) together, and is much stronger (at close range) than the electromagnetic force repulsion that makes protons repel other protons. (Magnets do not do this: two like poles will never stick together). In order to get a proton to strike another proton (or a nucleus that contains several protons) they must be traveling at high relative speeds; if their closing velocity is not great enough, they will never get close enough to stick together, because they strongly repel each other. But, just as you can make two of the same magnetic poles touch each other by providing sufficient force, so too can protons touch when they have sufficient relative speed. This can take place in the center of the sun, where the temperature is extremely high. Temperature is related to atomic motion: the hotter something is, the faster its atoms are moving [] see demo food coloring in water[]. Table 1 shows the nuclear reactions that are taking place in our sun, as well as nuclear reactions that take place in stars that are either older than our sun, or hotter than our sun. The reactions in columns 2 and 3 occur after a star has entered the red giant phase. How fast a star evolves to this point depends on its mass: stars heavier than the sun can reach this phase in less than 5 billion years (the age of the sun) whereas stars with about our sun's mass take about 10 billion years to get there. The particles you may be unfamiliar with are: n the neutrino, g a gamma ray (high energy light wave), and b+ the positron (the antimatter version of the electron). TABLE 1.

HONDA Report Essays

HONDA Report Essays HONDA Report Essay HONDA Report Essay Introduction. Soichiro Honda was born on November 17, 1906, in Hamamatsu, Shizuoka, Japan. He was a racer, a businessman, and a manufacturer. He dreamed of a better way of making piston rings, founded a small company, and began production. He was also a Japanese engineer and industrialist, and founder of Honda Motor Company, Ltd, which is a Japanese multinational corporation primarily know as a manufacturer of automobiles and motorcycles. Headquartered in Japan, Honda Motor Company is one of the major producers of quality motor vehicles around the world. Honda Motor Company is by far the worlds biggest motorcycle maker since 1959. Hondas quality, innovation and reliability have made it one of the most sought after car brands in the world. Its major car models such as Accord have occupied the leadership position in global sales for years now. Honda cars are also renowned for their fuel efficiency and have a loyal customer following all around the world. Hondas leadership position is sustained due to its enormous focus on RD, quality and innovation. Along with Toyota, its major competitor, Honda has ruled the US markets with its uccessful models and captured market share of American manufacturers such as GM and Ford. This success turned Hondas focus to another dream, the American Dream, and the company also moved away from other companies who relied upon distributors to sell their bikes when the company set up its headquarters in the west coast of America. Company overview 0 Honda has grown to become the worlds largest motorcycle manufacturer and one of the leading automakers. Honda develops, manufactures and markets a wide variety of products ranging from small general-purpose engines and scooters to pecialty sports cars, to earn the Honda Motor Company an outstanding reputation from customers worldwide. The Companys business is carried out through four segments: The Two-Wheel segment manufactures two-wheel vehicles All-terrain vehicles (ATVs) Personal watercrafts And other related products. The Four-Wheel segment offers four-wheel vehicles and other related products. The first production automobile from Honda was the T360 mini pick-up truck, which went on sale in August 1963. He was produced as a conventional rear wheel drive pickup truck, a flatbed with folding sides, and as a covered van. But, Hondas major car models include its best selling Accord, Civic, CRV, Hybrid car Insight and its luxury range of cars under the Acura brand. The Accord automobile followed in 1976, the same year that American Honda released its first automatic transmission motorcycle, the CB750A. The Honda Civic is a line of subcompact and subsequently compact cars. On the automotive side, Honda became the first manufacturer to finish first, second and third in the Motor Trend Import Cars of the Year selections. The word ? « civic ? » means of, or relating to a citizen, a city, citizenship or civil affairs. As its name suggests, the Civic incorporated Hondas wish to create a car for all people, a car for the world. The Financial segment in engaged in the provision of financial and insurance services. The General-purpose and Others segment is engaged in the manufacture of general-purpose products and its related products. Headquartered in Tokyo, the Company has over 400 subsidiaries and over 100 associated companies in Japan, North America, Europe, Asia and other districts. It is essential that Honda Motor Company focused on making its cars more fuel- efficient. To make this idea work, Honda will need to spend heavily on continuous research and development. Such R process is an on-going activity at progressive and innovative organizations like Honda. Hondas engineers will need to think out of the box and come up with innovative technologies that can really set apart Honda from its compet itors. Focusing on high HP-to-weight ratio engines and environment friendly hybrid vehicles will help the company to protect its market share in the future. For example, the two seated Insight model, which derived its power from a ombination of a 3-cylinder gasoline engine, and a large battery pack providing power-assist during acceleration was a good start. Another innovation is the use of ethanol as an efficient and more environment friendly gas substitute. Honda Motor Company needs to create new models or redesign existing models to be more friendly and geared for comfort of the older generations, such as the baby boomers. This comfort should be teamed with a fashionable look, as baby boomers dont want to be reminded of their aging bodies. To come up with this range of product mix, Honda will need to make significant capital expenditure. However, this strategy can be dangerous as Honda might lose its focus. In an effort to capture this segment of the marketplace, Honda might lose its quality and strategic focus. However, if this option is pursued, Honda will need to raise capital in the form of equity as well debt in a suitable combination to fund this capital expenditure. 0 Honda is already expanding their U. S. production, today, 80% of the 1. 3 million cars Honda sells in North America are made at North American factories, and the parts in Hondas American cars increasingly come from local suppliers. Honda plans to increase its production from the current 1. 4 million units a year to 1. 62 million units within a year. This new growth should be put in areas where the cost of living is relatively low. This will ensure that Honda can pay workers fair wages for the area. Creating a loyalty to American made products is no t the only reason that Honda needs to expand its local production levels. Since over 70% of revenue for Honda is gained in America, it is important to make the vehicles where or close to where they are sold. With the ever-changing exchange rate between the United States and Japan, local production gives Honda stability. This helps Honda to be much more resistant to exchange fluctuations, says Satoshi Aoki, senior managing director at Honda in To Conclusion Unlike other global businesses that see size as the key to survival, Honda embraces the ideal that even as Honda operations expand around the globe, they want to maintain the qualities of a small company that is close to its customers. The ability to produce a worthwhile product with the speed, flexibility and efficiency of a small company and the essential elements of a large company global reach and echnological strength, is what drives them into the future and will continue to help them strategize their global efforts. Hondas global strategy is very simple put cost-effective plants in areas that best meet the needs of local customers. They integrate plants into markets with a Small Born manufacturing strategy, starting small and then expanding as local demand increases. This thinking has helped them establish more than 100 factories in 33 countries, an approach that allows Honda to achieve efficiency and profitability, even at low production volumes.

The Definition and Description of Geological Erosion

The Definition and Description of Geological Erosion Erosion is the name for the processes that both break down rocks (weathering) and carry away the breakdown products (transportation). As a general rule, if rock is just broken down through mechanical or chemical means, then weathering has occurred. If that broken-down material gets moved at all by water, wind or ice, then erosion has occurred.   Erosion is different from  mass wasting, which refers to the downslope movement of rocks, dirt, and regolith primarily through gravity. Examples of mass wasting are  landslides, rockfalls,  slumps,  and soil creep. Erosion, mass wasting, and weathering are classified as separate actions and often discussed individually. In reality, they are overlapping processes that usually act together.   The physical processes of erosion are called corrasion or mechanical erosion, while the chemical processes are called corrosion or chemical erosion. Many examples of erosion include both corrasion and corrosion. Agents of Erosion The agents of erosion are ice, water, waves, and wind. As with any natural process that takes place on the Earths surface, gravity plays a major role as well. Water is perhaps the most important (or at least most visible) agent of erosion. Raindrops strike the surface of the Earth with enough force to break apart soil in a process known as splash erosion. Sheet erosion occurs as water collects on the surface and moves toward small streams and rivulets, removing a widespread, thin layer of soil along the way. Gully and rill erosion occurs as runoff becomes concentrated enough to remove and transport larger amounts of soil. Streams, depending on their size and speed, can erode away banks and bedrock and transport large pieces of sediment.   Glaciers erode through abrasion and plucking. Abrasion occurs as rocks and debris become embedded on the bottom and sides of a glacier. As the glacier moves, the rocks scour and scratch the surface of the Earth. Plucking takes place when meltwater enters cracks in the rock beneath a glacier. The water refreezes and breaks off large pieces of rock, which are then transported by glacial movement. U-shaped valleys  and  moraines  are visible reminders of the awesome erosive (and depositional) power of glaciers.   Waves cause erosion by cutting away at the shore. This process creates remarkable landforms like wave-cut platforms, sea arches,  sea stacks, and chimneys. Due to the constant battering of wave energy, these landforms are usually short-lived.   Wind affects the surface of the Earth through deflation and abrasion. Deflation refers to the removal and transport of fine-grained sediment from the winds turbulent flow. As the sediment is airborne, it may grind and wear away surfaces with which it comes in contact. Like with glacial erosion, this process is known as abrasion.  Wind erosion is most common in flat, arid areas with loose, sandy soils.   Human Impact on Erosion Although erosion is a natural process, human activities like agriculture, construction, deforestation, and grazing can greatly increase its impact. Agriculture is particularly notorious. Areas that are conventionally plowed experience upwards of 10 times more erosion than normal. Soil forms at about the same rate that it  naturally erodes, meaning that humans are currently stripping away the soil at a very unsustainable rate.   Providence Canyon, sometimes referred to as Georgias Little Grand Canyon, is a strong testament to the erosional effects of poor farming practices. The canyon began forming in the early 19th century as rainwater runoff from the fields caused gully erosion. Now, just 200 years later, guests can see 74 million years of beautifully layered sedimentary rock in the 150-foot canyon walls.

World civilizations Essay Example | Topics and Well Written Essays - 1250 words

World civilizations - Essay Example The first crusade lasted between 1095 and 1291. Pope Urban officially launched the first crusade in France. The focus was to aid those Christians living in the East. Pope Urban II told the people in France that the Muslim Turks were torturing and oppressing Christian pilgrims visiting Jerusalem and other holy lands. As a result, he appealed to the Knights to fight for their religious city. During the crusade, the absolution of sin and eternal life was promised to the people who also hoped to attain wealth and land in the East. With the endorsement of the Byzantine emperor and guided by the Armenian Christians, the knights walked from Syria and Turkey to Jerusalem. The first crusade focused to retake and recapture Jerusalem. The Muslims had captured the city of Jerusalem in 1076. Muslim soldiers oppressed and tortured any Christian who wanted to go to Jerusalem. This cruel treatment angered Christian. This prompted Pope Urban II to declare war against Muslims (Pomeranz et al, 2010). Many Christians at that time were determined to reclaim Jerusalem because of their faith and drive Muslims out of the city with all means. Some Christians understood that they had sinned before God and therefore, going to war with Muslims, God would forgive their sins. Pope Urban II had informed Christians that in case they died in the war, they would go to heaven because they were struggling and fighting for God. Crusaders who went to Jerusalem were exempted from paying taxes; therefore, they were determined to go to war so that the church would guard them. In addition, Christians thought that by going to war to recapture Jerusalem, they would claim wealth that they thought existed in the city of Jerusalem. The Byzantine emperor appealed to the papacy and western Christendom to come to rescue of Constantinople by staging a revolt or crusade that would free the city of Jerusalem from the Muslims. In addition, Christians

Case 2; Atomic company Essay Example | Topics and Well Written Essays - 750 words

Case 2; Atomic company - Essay Example In the case study there was internal conflict between Ramon Fernandez, VP finance, and the VP of sales Roger Post. â€Å"Conflict occurs when parties disagree over substantive issues or when emotional antagonisms create friction between them† (Schermerhorn, Hunt, Osborn, 2003, pg. 378). The changes in Atomic’s manufacturing methods since its inception in 1946 are not unusual. The textile and apparel industry used to generate thousands of jobs in the United States. This industry has always been a labor intensive industry (Bls, 2011). The spread of the globalization movement created new opportunities for corporations to establish operations in other foreign markets where labor and materials cost are lower. The firm selected China as its optimum location for manufacturing. Today China is the world’s largest exporter of goods (Thompson, 2010). The decision the company made to outsource its manufacturing function was the best alternative for the company. After reading the case study I came to the conclusion that the success of the Tiger Pants line was due to the strategy that Roger Post implemented of giving out clothes to celebrities. When consumer saw the Tiger Pants been used by famous people it gave them an extra incentive to purchase the pants. The strategy was very smart, but I cannot attribute the incredible success of the clothe line to just that factor. A lot of the credit of the clothes line goes to the designer of the pants. I also think that luck played a part in the success of the clothes lines because nobody expected the tremendous growth of Tiger Pants. In the case study the vice president of sales, Roger Post stipulated that it was going to be extremely difficult to generate an estimate of sales for 2003. His sales estimate was between $5 million and $20 million. I believe that the boom of the product was a fad, but due to the brand value the company established sales will be solid. My

Business management - Essay Example China is one country which escaped from the current global financial crisis without much damage. As per economic gurus, China’s economy will surpass that of the US’s within 20 years of time. Earlier, China was reluctant in opening their economy, but at present their economy is more transparent than even Japan’s economy. Moreover, China’s trade in 2004 was equal to 70% of its GDP, while that of Japan was 24%. China received $60.6 billion of foreign direct investment in 2004, while Japan, received only $20.1 billion (Overholt, 2005, p.5). China has adopted an economic policy in which they were ready to open the unimportant sectors for the FDI whereas the critical sectors were kept under government control only. They have encouraged privatization in many small scale industries and less important industry sectors and that also in bulk. Xinhua, Chinese daily, has quoted the opinion of the World Bank chief economist, Deepak Bhattasalithe recently. He has told to the Chinese daily that, not only the Chinese Governments effective policies on taxation, but its long-term investment in infrastructure construction also contributed to a more pleasant investment climate (Xinhua, 2004). There is no second opinion about the immense economic developments happening in China. Economic growth of a nation is controlled by many parameters like, political stability, lack of agitations in the society or industrial sectors and also the country’s ability to mobilize the internal resources along with attracting foreign direct investments (FDI) in the country. The people’s living standards, unemployment problems, educational levels, infrastructure developments, overall domestic peace levels and also the relationships with the neighboring countries, all will reflect the economic growth of a nation. China has all the above qualities and hence corporate can think about investing in China. China is the number one country in the world as

Normal Business Operations Essay Example | Topics and Well Written Essays - 1250 words

Normal Business Operations - Essay Example Within this understanding and appreciation for the means by which key strengths, weaknesses, opportunities, and threats define the way in which this particular store will continue to integrate with customers in the near future, the following analysis will seek to provide something of a SWOT analysis with regards to this chain in the hopes that by understanding these key areas, the analyst will be able to define and appreciate the areas of opportunity and potential threats the firm faces both in the present and within the near future. Strengths: Firstly, with regards to the key strengths that Reeds grocers have within the current market, these can basically be understood with regards to the fact that they have established a resilient and well respected brand image among the client base and they also exhibit a resilient strength of the size and scope of their grocery store locations and offerings. Starting from a humble family owned beginning, Reeds transitioned over time, just as have so many other small firms, to encompass a great many stores and a wide variety of product and service offerings. Moreover, consumers of the firm have come to respect them within the world of grocers. This market presence along with a substantive level of respect and appreciation by a rather large client base is a net asset as well as a definitive strength upon which the firm can seek to leverage any further market growth or development within the near future. ... Another key weakness that the grocer faces is with regards to the fact that it cannot count on loyal consumers to carry it through economically difficult times. Whereas in the past grocers could count on loyal consumers to continue to derive a degree of revenue/sales, the current model indicates that less and less consumers are ultimately loyal to a single grocer and choose instead to shop many grocers in an attempt to maximize their savings. This represents an effective weakness that the firm is no longer able to attract and retain loyal consumers within a market that is more and more cut throat with regards to overall earnings and sales. Opportunities: Political/Legal With regards to the political/legal opportunities that the firm should seek to leverage, it is the understanding of this analysis that the firm, as well as any and all other firms within the system, should continue to engage with law makers and governments (at both the regional, state, and federal level) to continue t o lobby for tax breaks and business incentives so that they may continue to provide the most basic of goods to the consumers that they provide for; the need of sustenance. Economic Similarly, with regards to the economic opportunities that the firm is faced with, these can be understood with regards to seeking to model their business plan, at least in part, upon the runaway success that many of its greatest competitors have employed; i.e. offering at least a portion of overall goods to be sold as bargain buys and priced within the reach of a specific demographic of consumers that would otherwise be attracted to other stores instead. This serves as an economic opportunity that can be leveraged with very little overall cost to the firm and
