Chemistry lab paper sherlock holmes experiment Essays Chemistry lab paper sherlock holmes experiment Essay Chemistry lab paper sherlock holmes experiment Essay Our objective for the Sherlock Holmes Experiment was to illustrate that some chemicals can be identified or differentiated by simple chemical tests, such as solubility, pH, or color tests. In our group we had to test come common powders such as Alkali-Seltzer, baking soda, flour, Vitamin C (ascorbic acid), and salt. Other chemicals that were used to do this experiment were vinegar, and Iodine 2 Solution. The equipment used to do this experiment was red litmus paper, and 5 test tubes per group. After all materials were gathered, we then had to do five different tests to determine what the powder material does. The first test was to see what the powder materials do in water. We had to add a scoop of each of the common powders to an equal amount of water, each in a separate test tube. Then we had to stir/shake it up and record our observations. We had determined that the flour did not dissolve in water. The vitamin C did dissolve in the water. The salt, Alkali-Seltzer, and baking soda also did not dissolve in the water. In the second test we did, we had to determine what each solution does with litmus paper. We had dipped a piece of red litmus paper in each test tube and then observe what happens. When we put the litmus paper in the flour, Vitamin C, and salt, the litmus paper stayed the same color (red) and there was no reaction to either of them. However, when we put the litmus paper in the Alkali-Seltzer, and baking soda, the litmus papers turned too blue color. In the third test, we had to add a squirt (half ml) of vinegar in each test tube to observe what happens. When we put vinegar in the flour, we observed that a milky like solution was made. When we put vinegar in the Vitamin C and the salt there was no reaction to either of the common powders. The Alkali-Seltzer, and the baking soda, hen mixed with vinegar, had a bubbly/foaming reaction. In the fourth test, we had to add a squirt (half ml) of Iodine 2 solution in each of the test tubes to observe what takes place. For the flour, when mixed with iodine, had turn too black color with no physical/chemical reaction. The Vitamin C turned to a red/orange color with no physical/chemical reaction. For the salt the solution turned to an orange color with no physical/chemical reaction. With the Alkali-Seltzer, the solution turned to a brown color with no reaction as well. Last but not least, the Baking soda turned to an range/brown color with no reaction. In the last test, we had to test out a mystery powder (powder A, B, C), in its own separate test tube, in order to solve the Sherlock Holmes Mystery. Our group had powder C. When we mixed water in the mystery powder, it did not dissolve. When the litmus paper was put into the test tube it turned blue. When the vinegar was mixed it bubbled/foamed up. When we mixed the iodine solution, there was no reaction and the solution turned to a dark brown/black color. When we mixed in the baking soda there was no reaction and it turned to an In conclusion, after we had tested the mystery powder, we had to solve the mystery of who stole Kamala Jacksons pad. There were four suspects which were, Ruby, alma, Manly, and Beau, who were seen at the time the pad disappeared. I then cancelled out all the common powders that had no comparison to the mystery powder. The flour, vitamin C, and salt did not have any comparison which left only the Alkali-Seltzer and the baking soda. The comparisons of the Alkali-Seltzer and the baking soda were very similar. They were Just about the same as the mystery powder. So I then narrowed down the two suspects, Beau, and alma, who could have possibly stolen Jambs pad. My accusations of the culprit narrowed down to Beau. I say this because even though alma was baking cookies, she did not use baking soda to make her cookies, as you would think when someone is cooking they might use baking soda as an ingredient. So then I did my research. Beau is the only person left because at the time of the disappearance of the pad, Beau was using Alkali-Seltzer tablets. Alkali- Seltzer tablets contain citric acid and sodium bicarbonate (baking soda), which lead to my accusation that the culprit is Beau.

Manchester airport Essays

Manchester airport Essays Manchester airport Essay Manchester airport Essay There are many similarities between the locations of school and Manchester airport . One similarity is that both businesses are situated near busy motorways. Having motorways could be a good thing as it would raise the profile of both Manchester airport and school. Another similarity is that both have or own a train station near by, this means that anybody could travel to school or to Manchester airport. This way would help as there would be more people going on the train which means that there would be a lot of relief for drivers on the road. It also means less traffic congestion meaning less traffic accidents in the year. One difference is where the location of each business is one is in the south end of Manchester as you can guess it is Manchester airport and another is located in Morley in Leeds which is Bruntcliffe High school. Both locations are situated where it isnt too busy to get to and from. Another difference is that near by the school there is a retail park which also could raise their profile, Manchester airport is based around fields and motorways nothing that could draw up attention for the business. The school is also close to many suburban areas not like Manchester as it is just close to a big city. There are loads of other schools situated around Morley so the school has to keep up their profile; Manchester airport has only one competitor itself this is not a problem, there is only one main airport in Manchester and this is it. A2 Compare the activity of the school Manchester Airport There are many similarities between the school and Manchester airport. One is that both are providing a service e. g. Manchester airport is providing the service of flying and the school is offering students an education. A difference between Manchester airport and the school is that Manchester airport can gain profit whilst the school doesnt gain anything other than helping students get an education. Another similarity is that both Manchester airport and the school are on their guard as there are many competitors around. Also both Manchester airport and the school are trying to up their games a bit as with the competition around. The one and only change to the school would be changing it from the public sector to the private. This means that students would have to pay to go to school. Which also means most of the students currently at Bruntcliffe would not be able to afford fees so the number of students going there would fall. I think this idea wouldnt be good as if the school was in debt then the government wouldnt pay it for them as it is in the private sector. A good thing about this would be that the Results, facilities attendance should improve. If the school was closed down then it wouldnt be able to open. The school wouldnt have enough money to reopen it and would have to raise some money and some profile as everyone would know that the school had been closed down and would want to know why. A school in the public sector would be closed by the government and opened by the government; of course the school in the public sector would also have to raise some profile. Also you could go into a partnership but doing this you would lose all your possessions and the business could go bust, also there would be the risk of arguing. A3 Suggest justify changes to the ownership of Manchester Airport One thing that you could change about Manchester airport is by allowing private investors invest as at the moment only shares are held by local council and the public sector (government). But this means that you would have to sell to someone that you dont know, if you sold to the council then you ask someone to verify that person who is investing. Another thing is changing it back to the private sector this would mean people would have to pay to use their service and it wouldnt be open to the public anymore. Already 10 councils own Manchester Airport and are involved in decision making so changing sector would have little affect here. It would not work as a sole trader as Manchester airport is in the public sector and it is really busy and one person would not be able to afford to keep the business running. A3 Suggest justify changes to the location of the school The school could move to the more populated area, this meaning that there would be more people attending the school. The school could also move nearer to a retail/business park to attract more attention. At the moment the school is close to many different villages this could be an advantage for Bruntcliffe as the more villages the more students they could take on in school. There is a disadvantage of being based near a motorway it is a problem for the school as it would make it unsafe for children/students. The school could move to a more private place but they would risk loosing students. A3 Suggest justify changes to the location of Manchester Airport Manchester airports location is very close to lots of motorways. This is an advantage as there will be easy access for deliveries. A disadvantage of this would be the build up of traffic. They could also move in to the city centre as there will be more population, an advantage of this could be making more money. Manchester airport at the moment is based near houses, if it moved to the city centre there would be more houses and it would be easy for people to travel to. A disadvantage of this would be the loud noise it might force people to move away but however the nearer it is to the city centre the more surrounding people would fly with them. A3 Suggest justify changes to the activity of the school The activity for the school is providing a service for the students. The school could change this and become part of the secondary sector, by producing its own goods e. g. books, materials. The school could also expand by building outreach centres in local and public areas. To maintain their standards and think that the school should regularly invite younger children to experience their time in high school. You could design your own school/exercise books. I think this is a good idea because it would mean less money spent on buying books with a logo/design and more money spent on the things that are more important. More student work on display. I think that it would be a good idea, because it means that not only are you respecting the work of a student, you will also be saving money because you are buying random posters with no meaning against it. A3 Suggest justify changes to the activity of Manchester Airport Manchester airport provides a service to people who want to fly with them. Other businesses could set up at the airport and increase their profile. I think it would be a good idea if you had quicker departure times because it would mean that more customers are willing to fly from Manchester airport because of the consistent flight times. I think that if you make the international flights cheaper more people will fly to international countries like the Dominican Republic and Cuba.

Inventory Management Research Paper Example | Topics and Well Written Essays - 250 words

Inventory Management - Research Paper Example This means that the employees order new stock as soon as the existing one is depleted. Full maximization of employee use is essential in times of failure of the system. Many businesses have employed the use of self-checkout machines in retailing to enhance productivity. Among the major advantages of these machines is the improvement of efficiency in that they reduce the checkout time. A store can run six self-check units all controlled by one employee who tracks the progress of all customers in all the machines as opposed to one cashier and thus reduce time. The customer also gets a false sense of privacy thus improving satisfaction and productivity. For a retailer, there is reduced staffing and therefore reduced cost of management due to less administration costs. The machines enhance efficiency in the payment as they accept many methods of payment such as the debit and credit cards, cash through coin slots and electronic food assistance cards. However, the system is vulnerable to theft from shoplifters. The trustworthiness of customers is questionable but the machines may detect incidences of theft and cause the customer to change attitude toward s

Curriculum and Instructional Adaptations, Attitudes and Collaboration Research Paper - 1

Curriculum and Instructional Adaptations, Attitudes and Collaboration for Students with ADHD in an Inclusive Setting - Research Paper Example Curriculum and Instructional Adaptations, Attitudes and Collaboration for Students with ADHD in an Inclusive Setting ADHD is characterized by poor attention spans, being fidgety and restless, heightened variability of task performance, impulsiveness, distinctly observable hyperactivity and inability to exhibit compliance with rule-governed behavior. Such children are easily identifiable and the usual reporting party is either the parents or the teachers’ at the primary level of education of such children. Unless special strategies and instructional adaptations are made for such children at the right stages of their life, they run the risk of being school dropouts and slipping into an abyss of psychological disorders in their adult life. The primary focus of a teacher should therefore be to be well equipped to identify behaviors associated with ADHD in the classroom environment. The classroom has been adjudged as the best environment where such students’ can be recognized. Ready availability of children for developmental comparisons in the classroom and special demands placed on them for attention, learning and self-control elucidate the differences between them, if any. Multiple criteria for diagnosis of such children are described in the American Psychiatrist Association’s Diagnostic and Statistical Manual and a well trained and informed teacher is the best candidate to identify such children due to the close proximity, consistent contact and direct observation/evaluation of task handling abilities by them.

U.S. Totalization Agreement With Mexico Essay Example for Free

U.S. Totalization Agreement With Mexico Essay The focal point of this paper is to analyze the Totalization Agreement between the US and Mexico. It should be noted that the aspects of this analysis is not fundamentally policy analysis but it intended towards presenting arguments from the point of view of analytical framework. In this paper there would not be any bias or opinion presented rather a comparison would be presented in terms of arguments for and against the issue. It should be stated that in the context of globalization the Totalization Agreement is a very important aspect for the US. Totalization Agreement has the tendency of investment funds and businesses to move beyond domestic and national markets to other markets around the globe, thereby increasing the interconnectedness of different markets. Globalization better said is the shift in the direction of a more incorporated and interdependent World economy. Globalization has had the effect of markedly increasing not only international trade, but also cultural exchange. some intellectual define globalization as convergence of prototypes of manufacture and expenditure and a consequential homogenization of customs, while others strain that globalization has the prospective to take countless miscellaneous appearances. In economics, a wide description is that globalization is the union of prices, wages, products, profits and rates of interest in synchronization with developed nation norms. Globalization of the financial system depends on the position of international business, human migration, incorporation of pecuniary markets, and mobility of capital. The International Monetary Fund observes the increasing financial interdependence of countries all over the world through rising quantity and multiplicity of cross-border dealings, gratis international capital flow, and comparatively faster and extensive dissemination of technology. In contemporary economic scenario the prevailing trend is expansion in the global market. Global market expansion is nothing but a concept of serving customers beyond the limits of domestic market and in economic scenario considered a key growth strategy. Global market expansion is a business reality that every company encounters at some point in its evolution. Under such circumstances every business venture must balance risk with rewards, the risks when expanding internationally can be less predictable and in the same way the rewards can be more elusive. The companies, which are looking for sustainable ways to grow and diversify their revenue streams, consider global expansion as a strategic option. There are several factors behind the trend toward expansion in the global market. Companies require a global presence. For both offensive and defensive causes, companies cannot overlook opportunities outside their home markets. A company’s requirement for a global presence arises from two factors, their capability of leveraging domestic relationships outside their country and a requirement from domestic customers to support the company’s products internationally. A global expansion allows companies to replicate successful domestic strategies in international markets, potentially in markets with lower competitive intensity. Additionally Global market expansion provide the companies large untapped markets, advantages of low labor costs, savings of shipping costs, speed and efficiency of delivery system, etc. These factors make the Totalization Agreement between the US and Mexico more important. (Fletcher, 2006) The Totalization Agreement between the US and Mexico could be better understood in the light of the history behind it. For more than thirty years US has been establishing agreements relating to social agreement internationally keeping in mind that these agreements should coordinate with the program by the Social Security of the US. These agreements based on the aspects of programs related to Social Security of the US are cumulatively pronounced as totalization agreements. Under these agreements there are certain advantages. However, from the point of view of the US these advantages can broadly be divided into two parts. The first objective is to eradicate double taxation for workers employed in foreign nations. Without the agreement an individual would have to pay two times as tax on the earnings. The current report suggests that the benefit of Totalization Agreement between the US and other countries has help US workers working abroad at lot. The cumulative savings are estimated at $800 million per year. The second objective of Totalization Agreement between the US and other countries is to provide an individual who is part timer as a worker in either in the US or the foreign country the proportional tax benefit that is so important for the worker. In this context the agreement between US and Mexico becomes very important in the context of financial benefits. It has been estimated that once the agreement of Totalization is signed between the US and Mexico the workers from the United States in Mexico would be able to save about an estimated $140 million. These savings would be made in the parameters of Mexican taxes relating to health insurance and social security measures. However, it should be mentioned that this estimation is calculated on the basis of a 5 year term of computation. Again, in the perspective of humane benefit it would immensely help the workers who have been working in Mexico for a shorter period of time in both US and Mexico as because this agreement would help them to receive the benefits. (King, 2006) It could well be stated that Mexico is a prominent partner of the US in terms of trading. In fact it is the second largest after Canada. This way it becomes important for the US to indulge in Totalization Agreement with Mexico. As it is Mexico is already under the Totalization Agreement with Canada making it mutually beneficial for both countries. The advantages and disadvantages of Totalization Agreement with Mexico have been heavily scrutinized and debated in recent years. Proponents of Totalization Agreement with Mexico say that it helps developing economies catch up to highly developed industrialized economies much faster through increased employment and technological advances. Critics of Totalization Agreement argue that it weakens national sovereignty and allows rich nations to ship domestic jobs overseas where labor is much cheaper. The main advantages of Totalization Agreement are as such, increased free trade between the two nations, increased liquidity of capital allowing investors in developed nations to invest in developing nations, conglomerates are having greater flexibility to operate across borders, global mass media binding the world together, increased flow of communications allowing vital information to be shared between individuals and conglomerates through out the globe, greater facility and speed of transportation for goods and people, reduction of cultural barriers increases the global village effect, spread of democratic ideals to developed nations, greater interdependence of nation-states, reduction of likelihood of war between developed nations , increases in environmental protection in developed nations. Along with the advantages there are also several disadvantages of Totalization Agreement, such as increased flow of skilled and non-skilled jobs from developed to developing nations as companies look for the cheapest labor, increased probability of economic disturbances in one nation effecting all nations, business influence of nation-states far exceeds that of civil society organizations and average individuals, apprehension that control of world media by a handful of conglomerates will limit cultural expression, greater possibility of reactions for globalization being violent in an attempt to conserve cultural heritage, greater danger of diseases being transported inadvertently between nations, spread of a materialistic lifestyle and outlooks that sees consumption as the path to affluence, international bodies like the World Trade Organization interfere with national and individual sovereignty, increase in the probabilities of civil war within developing countries and open war betw een developing countries as they compete for resources, decrease in environmental integrity as polluting corporations take advantage of weak regulatory rules in developing countries like Mexico. It could well be stated that in this competition organizations are gradually loosing their ethnic values and morals. Today competence of an individual or a corporate is judged by his or her ability to cope up with constant fundamental changes in the organizational structure. All over the world, organizations aligning new products engineering teams around ‘pit crew’ model. Cross functional teams to design, manufacturing sales and service engineer’s work along with the workers, who at some point of time have stake in the product. This ensures manufacturing and sales people having their say all through the design process and building up the manufacturing capability early on that is currant engineering. The goals are simple, such as speed, equality and competitive price. Commodities have become international for most industries and the impact of engineering is significant. In many organizations, the learning curve in engineering has become an unaffordable luxury. Competitive pressures mandate finding ways to reduce the total time required to introduce new products in the market. Competition along with more complex production and distribution environments requires identifying and reducing necessary costs, such as costs associated with development, manufacturing, distribution and service. However, it can be stated that totalization agreement would have a distinct effect on the Trust Funds but it would be a long termed and virtually negligible effect. It has been estimated that the social security of US bears a cost of about $100 million yearly. This has been the trend for the last 5 years. Thus the totalization agreement would enable the workers of both the US and Mexico to enjoy the advantage of cost benefit as the dual taxation would be eradicated. It should be mentioned in this perspective that the cost benefit of US during the year 2002 was around $198 million with Canada alone under the parameters of the totalization agreement. (Lamb, 2004) Thus in the conclusion it could be stated that there are both advantages and disadvantages in coming into a condition of totalization agreement with Mexico. However, when an international agreement is signed there are multiple aspects to be looked after and these are done keeping in mind the mutual benefits of the nations.

Handling the Issues of Rage and Murder in Poetry :: Education for Leisure The Hitcher Poems Essays

Handling the Issues of Rage and Murder in Poetry The two poems I am going to analyse are 'Education for Leisure' by Carol Ann Duffy and ' The Hitcher. These poems both have potentially dangerous speakers. The first line of 'Education for leisure' contains murderous feeling, this grabs the reader and submerses them into the poem. "Today I am going to kill something. Anything" The poet uses direct and powerful words, by using the word 'something' instead of 'someone' the poet makes it unclear what the speaker wants to kill. In 'Education for Leisure' the speaker thinks that his readiness to kill makes him somehow smarter then anyone else. This is shown when the speaker says; "I am a genius..." The speaker seems to kill for killing sake. This sadism is shown in line five when the speaker says; I squash a fly against the window with my thumb. We did that at school. Shakespeare." This can be interpreted in two ways, one way is that killing and Shakespeare can be associated with boredom. The other way is a line from 'King Lear' By William Shakespeare "As flies to wanton boys are we to the gods; They kill us for their sport." (4.1.57-58) Carol Ann Duffy uses this a another way of symbolising the speakers delusional view that he is a God. The poet reinforces the point that the speaker is delusional when he says; "The cat avoids me. The cat Knows I am a genius, and has hidden itself." The speaker thinks here that the cat thinks he is a God and has hidden out of fear, he thinks the whole planet revolves around himself. The speaker also thinks he is famous. " I dial the radio and tell the man he's talking to a superstar. He cuts me off." By now the speaker is probably getting very frustrated, he then takes a drastic step. "I get our bread-knife and go out. The pavements glitter suddenly. I touch your arm." By saying 'your arm' instead of 'someone's arm' Carol Ann Duffy brings the reader into the poem by making the point that people like the speaker do exist and this sort of thing could happen. The speaker in 'The Hitcher' is observably feeling very depressed. "I'd been tired under the weather," The speaker is presumably mentally ill, he picks up a hitcher "...in Leeds" One difference 'The Hitcher' has to 'Education for Leisure' is that in 'The hitcher' we know someone is killed. "I let him have it on the top road out of Harrogate - once with the head, then six times with the krooklok in the face..." even though we're not directly told that the hitcher is dead it's
