What Is Deuterium - Deuterium Facts

What is deuterium? Heres a look at what deuterium is, where you might find it, and some of the uses of deuterium. Deuterium Definition Hydrogen is unique in that it has three isotopes which are named. Deuterium is one of the isotopes of hydrogen. It has one proton and one neutron.  In contrast, the most common isotope of hydrogen, protium, has one proton and no neutrons. Because deuterium contains a neutron, it is more massive or heavier than protium, so it is sometimes called heavy hydrogen. Theres a third hydrogen isotope, tritium, which may also be called heavy hydrogen because each atom contains one proton and two neutrons. Deuterium Facts The chemical symbol for deuterium is D. Sometimes the symbol 2H is used.Deuterium is a stable isotope of hydrogen.  In other words, deuterium is not radioactive.The natural abundance of deuterium in the ocean is approximately 156.25 ppm, which is one atom in 6,400 of hydrogen.  In other words, 99.98% of hydrogen in the ocean is protium and only 0.0156% is deuterium (or 0.0312% by mass).The natural abundance of deuterium is slightly different from one water source to another.Deuterium gas is one form of naturally occurring pure hydrogen. Its chemical formula is written as either 2H2 or as D2. Pure deuterium gas is rare. Its more common to find deuterium bonded to a protium atom to form hydrogen deuteride, which is written as HD or 1H2H.The name for deuterium comes from the Greek word deuteros, which means second. This is in reference two the two particles, a proton, and a neutron, which make up the nucleus of a deuterium atom.A deuterium nucleus is termed a deuteron or deuton.Deut erium is used as a tracer, in nuclear fusion reactors and to slow down neutrons in heavy water moderated fission reactors.Deuterium was discovered in 1931 by Harold Urey. He used the new form of hydrogen to produce samples of heavy water. Urey won the Nobel Prize in 1934.Deuterium behaves differently from normal hydrogen in biochemical reactions. While its not deadly to drink a small amount of heavy water, for example, ingesting a large quantity can be lethal.Deuterium and tritium form stronger chemical bonds than the protium isotope of hydrogen. Of interest to pharmacology, its harder to remove carbon from deuterium. Heavy water is more viscous than ordinary water and is 10.6 times denser.Deuterium is one of only five stable nuclides that has an odd number of both protons and neutrons. In most atoms, odd numbers of protons and neutrons are unstable with respect to beta decay.The presence of deuterium has been confirmed on other planets in the solar system and in the spectra of star s. The outer planets have roughly the same deuterium concentration as each other. It is believed most of the deuterium present today was produced during the Big Bang nucleosynthesis event. Very little deuterium is seen in the Sun and other stars. Deuterium is consumed in stars at a faster rate than it is produced via the proton-proton reaction.Deuterium is made by separating naturally-occurring heavy water from a large volume of natural water. Deuterium could be produced in a nuclear reactor, but the method is not cost-effective.

Structured Process Operational Management

Question: Discuss about the Structured Process for Operational Management. Answer: Introduction The operational management is considered as the structured process of achieving the organisational goals. The essay focuses on developing the argumentative discussion based on the operational management issues faced by Hawkesbury Cabinets Pty Ltd. Operation management refers the business administrative process that is needed to be improvised to achieve the pre-determined goals. In presenting an argumentative essay, it is required to keep the concentration on the in-depth analysis of the underlying business incidents. These incidents have been creating the significant impact on the operation management process undertaken by the company. It is to be stated that the operational plan requires structuring the sequential process that can be beneficial for the upcoming future of the company. Undertaking the relevant decision is thus necessary (Nafari, Ngo Lehman, 2016). The case study is analysing the business operation process of Hawkesbury Cabinets, which manufactures the custom-built kitchen cabinet. The company was controlled by two main owners, Mei Chen and Fung. The primary objective of the company was to increase the sales ratio by manufacturing the custom-kitchen cabinet. This initiative had created the greater influences on organisational reputation within a recognised community. The owners of the company set their aims to capture a larger position in the market to ensure much profitability. The improvement of the quality parameter can be fruitful enough to darw the attention of the target customers (Wong et al. 2012). Therefore, it was decided to enhance the quality parameter of the kitchen cabinet that will be offered to the clients. The study will be providing the in-depth ideas about the recognised issues faced during implementing such beneficial strategies. The argument will be determining the diversified influences that the company ha d to face in the operation management process. Discussion It is mentioned that the company was focusing on improvising the quality parameter of the kitchen cabinets. This initiative was based on the operational management procedure undertaken by the company. At the first step, the company faced the serious difficulties in planning, designing, and execution process. The location-based issues were also foreseen in the operation management process. The analysis of the case study is thus needed to be much argumentative. It is noted that Hawkesbury Cabinets Pty Ltd requires identifying the current production system. The operational processes are mainly implemented in order to satisfy the needs of the community (Tano, 2013). During the business operations, the company faced the shifting demands of the target customers. In such time, the sales ratio of the existing products increased in a significant manner. The financial structure of the company also increased due to such growth in the sales ratio. Therefore, the company had the significant oppor tunity to manufacture the additional products by ensuring the small contract volume. The managing director of the company started concentrating on increasing sale value and deriving profits from the target market. Slack (2015) proclaimed that the company adopted the Job Shop manufacturing process, which was helpful enough to identify the proper quality parameter of the materials. This Job shop manufacturing process is considered as the fruitful process for sustaining the production of the small batches of builders kitchen. In fact, the company can even achieve the expectation level of the target customers. On the contrary, Burke (2013) presented the argument by stating that the proper manufacturing process requires the unique set up and structural steps. It is not easy procedure for any company to implement any operational plan without planning in a sequential order. The operational management process requires the investment of the proper capital resources (Lindberg, Voss Blackmon, 2013). The limited resources were another concern for the company. The obtained idea from this case study is highlighting that fishing and painting departments in the products are completely different to each other . Therefore, the company faced the hurdles in arranging the sequential process of executing the operational planning. The case study indicates that the company could not achieve the effective financial profits. In spite of the investments on the production, the company failed to structure the proper operational techniques to facilitate benefits. Simultaneously, it was seen the business faced the fundamental challenges associated with the invested costs in the product line. Golicic Smith (2013) pointed out that while undertaking the manufacturing process, it is required to follow the cost of the raw materials. Due to such production charges, the operational efficiency of the business was affected much significantly. If the company can keep the focus on supplying the materials from outside sources, it will be beneficial to provide the products perceived by the target customers (Kerzner, 2013). The discussion from the case study is also highlighting that the shortage of the space is also one of the major concerns for the company. If the company needs to expand the storage, more capital amount is neede d to be invested. It is clearly seen that the ineffective decision making process is the major reason behind such hurdles faced by the company. If the operation manager could undertake the sequential and effective procedure of executing the plan, it would have brought several benefits to the company. It is to be noted that the sudden decision of shifting to the production of the builders kitchen may create the significant effects on the financial structure of the company. It can be argued that if the company is completely focusing on continuing with the builders kitchen production, it is required to implement the job shop manufacturing technique. Due to the limited space in the existing manufacturing process, it is required to keep the focus on the storage available for implementing new techniques of manufacturing process (Meredith Shafer, 2012). It is important to note that the expansion of the storage is also much cost effective process. The company needs to invest more capital amount, which hampered the financial structure of the company. On the hand, the operational manager faced the significant challenge in undertaking the relevant decision regarding the investment process (Subramanian Ramanathan, 2012). Hence, it can be interpreted the operational management process under taken by Hawkesbury Pty Ltd. is creating the radical effects on the financial structure of the company. Conclusion The case study is based on the operational management procedures undertaken by Hawkesbury Pty Ltd. The critical arguments underlying the case study is highlighting the irrelevant decision making process. It is noted that the company tried increasing the revenue by considering the sales of the product line. The obtained idea form the above discussed arguments is specifying that the operational issues are mainly occurred due to the lack of proper sequential process. In fact, the irrelevant decision is also responsible for such issues. The inefficient planning of the operational management can hamper the entire organisational structure. Therefore, it is much important to engage the experienced operational manager who can structure the operational plan in a sequential process. The effective decision making is also necessary for the implementation of skilful operational plan. References Burke, R. (2013). Project management: planning and control techniques.New Jersey, USA.

Summary of Blade Runner Death and Resurrection

Alan Turing, the founder of artificial intelligence established the Turing Test to aid in differentiating between human and artificial intelligence among other things.Advertising We will write a custom book review sample on Summary of Blade Runner: Death and Resurrection specifically for you for only $16.05 $11/page Learn More The test symbolizes the move to believe that positions are not permanent, while essentialist ideas of human nature are diluted. This post-modernistic thinking argues that humans develop themselves through dreams, histories, myths, stories, and memories. Langer says that postmodernism is symbolized by numerous questions as human beings attempt to understand the mystery of this world. The breakthrough in genetic engineering and artificial intelligence makes it hard to differentiate what is imaginary from what is real among others. Films and cinematic texts give reliable resources of understanding our consciousness. Ironically, these resources give a notion of â€Å"present†, while in actual sense they establish an artificial understanding of space and time. Films impress patterns in our every day occurrences and together with statements and differences of our humanity thus shaping consciousness. Blade Runner is one of the films that show how humanity shapes its identity and the expectations it makes based on the nature of its surrounding. The film shows a world full of corporate greed and technological growth. It portrays the city of Los Angeles as a city that cannot be inhabited. While most of the reasonable people choose to live in the outer space, they encounter a crisis of living with genetically engineered beings referred to as â€Å"replicants†. The crisis narrows the boundary between artificial and human. The film shows the existing level of expectation and confusion in humankind by showing instances of constant happenings, disappearances, and flourishing information. There is a division in society such that people speak different languages. Besides, harshness in the society is so great that only adults live in the society. Technology has led to the establishment of social classes where the intelligent use and discard the less intelligent at will. As the film continues, it reveals that most of the people living in Los Angeles do not enjoy their freedom as their superiors direct them on what to do. Only those in authority like Tyrell enjoy freedom. The power-holders signify the shaping of a culture that uses and later throws away what it uses. Tyrell throws away Rachel (a replicant) after using her for a long period. The replicants’ abilities indicate the tailor-made work programs, employment arrangements, and production systems that currently exist in the modern corporations.Advertising Looking for book review on american literature?

There is no clear difference between the replicants and the real people as shown by the tests conducted. Man has made most of his understandings in his own image such that it is hard to distinguish the real from the artificial and thus man is in the struggle of establishing his identity. Blade Runner warns on the dangers of chauvinistic science that is dominating the postmodern world. The film portrays the Los Angeles of 2019 as a total ruin caused by men’s dominance. Men dominate everything. As the film shows the development of human images and their destruction, it brings out the idea of creation and death or destruction. The film uses a dove to signify its opinion that a law, which embraces feminism, ought to rule post-apocalyptic society characterized by corporate greed in a bid to deal with male dominance in the society.
