Chemistry of Hazardous Chemicals Week V multiple choice questions and Essay

Chemistry of Hazardous Chemicals Week V multiple choice questions and 2 questions - Essay Example The second method is the oxidation-reduction process. Most of the compounds decomposed by this method react explosively to thermal decomposition. For this reason, DOT does not allow carriers to transport them. A good example of these compounds is the ammonium dichromate (NH4)2Cr2O7(s), which decompose to chromium (III) oxide Cr2O3 (s), nitrogen (N2 (g)) and water (H2O (l)) on heating as illustrated in equation 2. Sulfur and finely divided metals are flammable; hence ignite readily at normal burning temperatures. In this regard, they can quickly expose ammonium nitrate to fire if not segregated. However, exposing bulk ammonium nitrate to fire may result in an explosive thermal decomposition of this compound to various products, including the toxic nitrogen dioxide (Meyer, 2010). As such, OSHA requires the segregation as mentioned earlier to prevent explosion of ammonium nitrate and life-threatening gases like nitrogen dioxide. This precaution is meant to ensure that ammonium nitrate does not leak into areas that it might be confined in case of fire. As seen from recent research (Meyer, 2010), exposing bulk ammonium nitrate to fire scenes results into its thermal decomposition at explosive rates, from which it might also produce the toxic nitrogen dioxide gas. Water is the primary solvent used to dissolve solutes. Additionally, metallic oxidizers are readily soluble in water. For this reason, their chemical reactivity is eliminated through diluting them in water. In doing this, the oxidation-reduction reaction of oxidizers is slowed down. As result, water as a solvent turns out as an excellent extinguisher of an oxidizer-supported fire. The compromised container will cause leakages of trichloro-s-triazinetrione or calcium hypochlorite stored in it. Being a strong oxidizing agent, it may cause thermal explosion. The primary rationale to support this argument is that the water left behind after the firefighters efforts to

Q5 - Essay Example The culture plays a major role in global information system management. Since the culture strongly influences management practices, such as decision making, policy-making, and system development strategies. However, the research on cultural dimensions offers a theoretical base that has been normally utilized for discovering the effects of cultural differences on the implementation and acceptance of information systems. These dimensions of culture are: (Kim & Peterson, 2003) Additionally, the complication of GIS development augments with the cultural dissimilarities in the countries concerned, particularly when the project manager is unable to recognize or distinguish the factors and overall situations that must be measured all through the global information system implementation. In addition, other complexities and challenges take place because of different languages, business, and official environments, vendor and technology help, national communications, local market size, the presence of local IT skills, and data export controls. Normally, culture differences affect global projects more than local projects because the straightforward and uncomplicated information system implemented locally can become a nightmare (a challenging task) if implemented globally (Biehl, 2007). Different techniques and technologies can be used to help resolve above discussed issues, for instance outsourcing is a best solution when workforce is less qualified. Social networks and other collaboration tools can be used to improve communication between international teams. As physical and logical security regulations are dissimilar, and they require to be tackled in cycle. Companies and Governments have previously spent hundreds of millions of dollars in the union of logical and physical security solutions. Security inside the business organization has previously been

Final project - Research Paper Example The school management shall be college managers with rich knowledge on the feed history of the school’s funding system and the college’s future plans on school funding. Saunders et al (2003) posit that there are six major forms of research design. Among others, case study shall be chosen as the preferred research design for this research work. Soy (1997) emphasizes that â€Å"case study research excels at bringing us to an understanding of a complex issue or object and can extend experience or add strength to what is already known through previous research.† In the context of this research, the complex issue or object at hand is the funding of Community College of Philadelphia. Cases study also comes with a specific point of data collection. The Community College of Philadelphia is the point of data collection. Data shall be collected from participants from both on and off campus. Data to be collected from participants shall deal with sources of raising funds for the college without putting any pressure on students. Sampling deals with the process of selecting respondents from among the population. The procedure or method used in sampling is referred to as the sampling technique (Koduah, 2007). There are several available sampling techniques. The researcher shall however use the purposive sampling technique to select the sample size. Purposive sampling has to deal with the selecting of respondents in a purposeful manner. This means that not all people in the population have an equal chance of becoming part of the sample size. The advantage with purposeful sampling is that it saves a lot of time in its implementation. Again, it helps in selecting only the most preferred and appropriate people with the right expertise for the research. Because the sampling technique is purposeful sampling, the participants shall be pinpointed by the researcher. The researcher expects 100% response rate since the sample size is relatively small.

How will Russia and Ukraine likely address their current and future Essay

How will Russia and Ukraine likely address their current and future conflicts in the coming decade Is war likely - Essay Example Issues of natural wealth, such as oil and gas, in the Crimea are very important to all actors involved in the region, including modern day Russia, the United States and Ukraine. Issues surrounding accessibility as well as resource scarcity have recently come to the fore and have involved all actors with a stake in the region. On the surface it may seem clear that the stronger regional power (i.e. Russia) would have the upper hand over Ukraine and eventually determine the fate of the relations between the two countries. Yet there are complexities that dictate the intrigues of international relations and foreign affairs. Ukraine, although is not yet a member of the European Union, is looking forward to NATO membership in order to safeguard its defense in an unforeseen political future. The most immediate resistance to Russia’s regional hegemony is the European Union, which continues to stymie its attempts to throw its weight around regionally (Recall the brief Russian-Georgian W ar last year caused by the break-away Republics of South Ossetia and Abkhazia). Still, the EU is burdened with the scarcity of natural resources and consequent economic dependence on other nations; 82% of its entire consumption of oil and 57% of gas makes it the world’s leading importer of fuels. The major supplier for these fuels is Russia, and this has been increasing following strategic investments and agreements from Russia. The EU is hampered by its economic dependence - a factor that cannot be overlooked. The isolation of Russia amongst the former members of the Soviet sphere of influence is a real threat to the decision makers in Moscow.

Research 5.10 - Lab Report Example Practical research will be used in this study. This type of research is the most effective type of research for it ensures that all aspects of the study are carried out. The advantage of this research is that the researcher has the ability to relate directly with the people in the area and this assists in getting more content for the research. This research is different from theoretical research since the researcher would just get information from people that have carried out extensive research on the region and as common with secondary research, it is open to bias and thus not a reliable source of information. Carrying out primary research provides critical information that secondary research may leave out (Chipev 85). Moreover, practical research addresses the issues facing the particular place at the time while secondary research may have outdated and unreliable research. The importance of carrying out this research is that very few people focus on animals in this region. Many people in the contemporary world either focus on plants and for those that pay attention to animals they focus on animals in dry lands and tropical regions (Chipev 103). Rarely do people research animals in the Antarctic region. Another reason for carrying out research in this region is that the researchers have the ability to offer the information that they acquire to the general public and environmentalists. The consequent of this is having people visiting the region and assisting in better conservation of the species. The length of the research is another issue that ought to receive concentration. An aspect that comes with this issue is the competency of the researcher. There are some researchers that are very poor at carrying out the required activities since they are not always after vital information but go out for the adventure while others just participate to earn money. Carrying out research on an animal is an activity that ought to take a considerable time. The

Ansewering the international business policy (questions) Essay

Ansewering the international business policy (questions) - Essay Example Dogs often put business strategists to their wits’ end as they worry what to do with them. Unprofitable business units, as a matter of fact, consume similar financial resources as their profitable counterparts. Hence, business strategists often undergo a serious decision-making to handle Dogs among the portfolios of companies they manage. Some of the ways to deal with unprofitable business units or product lines include: (i) establishing a partnership with a brand company that sells similar products; (ii) undergoing merger with another company; (iii) or selling the under-performing business units and invest the proceeds in other businesses that may yield some profits in the near future (Dalton et al., 2007). Selling of unprofitable companies have become the most popular option companies’ managers use to discard off low-yield business units in recent years. 2 2. Estonia, Latvia and Lithuania are examples of Baltic States. The prospect of finding new positions in their ma rkets may be remote due to the poor economic activities in these countries. For a new company entering the countries must resort to a policy of market development before it could assume the market leadership in these countries. The process of market development is a quite risky adventure because there is no 100% guarantee that it is going to be successful. The process involves using the company’s limited resources (both physical and human) to research the Baltic markets, analyse the available opportunities, undertake products’ publicity, and organise distribution channels that may be different from the ones available in the countries (Stonehouse et al., 2004). There are some common risks associated with market development. Some of these problems are cultural risk, financial risk, market risk and resource risk (Haberberg and Rieple, 2008). Some of the questions to be asked about this process are (i) what of if the cultures in the Baltic States are not receptive to forei gn participation in a particular industry in the country, say, hospitality industry? (ii) how could the company entering into the Baltic markets scrupulously manage its resources? (iii) And what are the possible market risks associated with this kind of business adventure? Once these burning issues can be successfully resolved, it will possible to for the new company to control the market it targets, and also reap the complete benefits this adventure will bring (Haberberg and Rieple, 2008). 3 3. In an economically viable country like Austria, competition among the business operators in the country is inevitable (De Wit et al., 2004). Engaging in â€Å"price wars† is one of the characteristic features of competition in the markets. Price wars force every player in the market to offer competitive prices that would draw consumers away from their rivals and promote continued patronage of what goods or services they offer (Winninger, 1994). To win these wars, some companies may of fer discounts on each of their products; they may also provide subsidies to state or non-private organisations to purchase large quantities of their products (Winninger, 1994). Other incentives for consumers include reduced Value Added Tax (VAT), free delivery mechanism and post-delivery services that many other companies

Nursing research Paper Example | Topics and Well Written Essays - 1000 words

Nursing - Research Paper Example The second step is the selection of participants within the clusters, that is, the participating students who volunteered for the intervention study (Chambers & Skinner, 2003). In determining the sample size, the research selected participants from fixed number of schools, but there was no restriction on the number of students per school. Furthermore, since there was no clear precision or specific characteristics for the sample, the selection method could be referred to unaided judgment. Among the issues related to the sample size is that they were from sixth and seventh grade classes with a mean age of 11.8 years. The purpose of the study is to take the participants through a program that would reduce development of devastating health problems among these participants. Another issue related to sample size is that among the participants, 53.0% were female, and since they were individuals still under adult care, 26.8% lived with both of their parents. Similarly, the selection criteria were based on volunteer by the participants with permission from their parents or guardians, and this also determined the sample size that the researchers ended up with at the end of the day. Moreover, there money was provided in exchange of participation, and given that these were students from low income families, this could have motivated the decision to volunteer, and thus, the sample size. Finally, there is the issue of low-income communities, which made the basis for the research, and thus, relates with the purpose of research. There is a good description of the purpose and all the issues related to this interventions research study. For instance, the intervention program is adequately described from the purpose, objectives, and all the requirements, as well as the participants. The level of measurement for the variables in this research was ordinary level of measurement, which ranges the variables from low to
