Mineral and Water Function Essay

Minerals and water play vital roles in the body. Lack of minerals and water in the human diet may result into serious health problems. According to Grosvenor and Smolin (2012), the body depends on the food taken in order to obtain minerals. Water is always obtained when one drinks water or from the foods taken. The most common and essential minerals needed in the body include calcium, iron, magnesium, potassium and zinc.Advertising We will write a custom essay sample on Mineral and Water Function specifically for you for only $16.05 $11/page Learn More Calcium helps in strengthening of teeth and body muscles. This mineral can be obtained mainly from milk products. Iron helps in distribution of oxygen in the body and can be obtained from meat, fish, liver and some chicken products. Magnesium is crucial in formation of bones and general workability of the nerves. Potassium balances the body fluids while zinc is necessary for growth and development. These m inerals can mainly be obtained from vegetables and animal products. Stanfield (2010) points out that just like the minerals mentioned above, water also plays a very important role in the body. This researcher explains that 90% of the body is composed of water. The body obtains a given percentage of water from foods taken, and through direct intake by an individual. According to Grosvenor and Smolin (2012), one of the main functions of water is to regulate the body temperatures. Many enzymes in the body work at given temperatures and therefore water ensures that such temperatures are attained for the enzyme-controlled processes to take place. Besides, water acts as a coolant, especially through perspiration. In addition, it acts as a lubricant, especially in the joints of the body. Its presence in the saliva in the mouth during chewing helps to avoid shock or damage emanating from friction of the joints. Stanfield (2010) says that without water, nutrients like proteins and carbohydra tes cannot be absorbed in the body. In this case, water helps the chemical reactions that make these two nutrients become absorbable in the body. Therefore, water is crucial in the whole process of food digestion and transportation of food nutrients and oxygen in the body. The above explained roles played by water show that it is one of the most important nutrients in the body. Lack of it may result into dehydration. As Stanfield (2010) points out, dehydration of the body poses serious impacts to an individual and can be life threatening. Some of the effects of severe dehydration include loss of general body weight, sight becoming dim, wrinkled skin, reduced urination, increased headaches and nausea, and weak immunity due to poor or no absorption of essential nutrients. Dehydration makes all the important body processes come to a stop, greatly reducing the working ability of the body, a condition that is fatal. According to Grosvenor and Smolin (2012), incidences where the body is d ehydrated should be avoided to avoid pre-mature deaths.Advertising Looking for essay on health medicine?

Although the body can generate water from some foods and fruits ingested, one should not rely on this as a source of water to the body. Stanfield (2010) recommends that one should take between 7 to 8 glasses of water a day or more when in exercise to avoid incidences that may lead to great water loss in the body. This would help one remain healthy and strong. References Grosvenor, M. B., Smolin, L. A. (2012). Visualizing Nutrition: Everyday choices. Hoboken: John Wiley. Stanfield, P. (2010).

Multiculturalism, Immigration and Welfare State essays

Multiculturalism, Immigration and Welfare State essays Multiculturalism, Immigration and their relationship with the Welfare State Issues concerning immigration within the Swedish Welfare state require a certain amount of individual pioneering on Swedens part. The policies that work for other countries cannot be applied in the same manner. Since Sweden did not have to take on any large number of immigrants (especially non-Scandinavian immigrants) until the time surrounding World War II it is still fairly new to developing its immigration laws. Many of the problems associated with immigration are more due to refugees in Sweden. Sweden grants asylum to a broad variety of individuals, consequently there are often certain groups in which many problems arise. A good example is that of a fairly recent incident involving Ethiopian refugees that came to Sweden. Now that Ethiopia has been deemed safe for their return the country will not take the refugees back, and these 400 or so people are stuck without a home, except in Sweden. Recently, especially with the creation of the EU, Swedish immigration policy has be come more efficient and well orchestrated. This seems to also be the case over much of Europe. In fact Germany even presented Sweden with an award recognizing their excellent achievements/improvements in immigration policy, and stated that they should lead the way in immigration policy making in Europe. Swedish immigration is not perfect yet though, and perhaps one of the best places to start looking is the relationship of immigration and the Welfare State. A popular view associated with the Swedish welfare state involves the idea of folkhem or peoples home. This basically means that the people will do what is best for their own home. So how does immigration fit into this policy? Immigration often puts a burden on this system. The first thing to consider is that many of the immigrants do not hold the same view of society as native-born Swedes...

Lit short paper - Essay Example He goes on further to say that he loves not only the Supreme but also the infinitely small – the thimble, spurs, plates and flower vases. The Supreme would point to god and that adoration comes naturally to creatures of God (which would include the poem himself). The enumeration of the above objects point to a consideration of their usefulness. The reader is given an inkling next of the poet as being a man who smokes. He starts the stanza by saying â€Å"For heaven’s sake, the planet is beautiful† as though to imply that it goes without saying that the world we live in is not only beautiful but filled with things like â€Å"smoking pipes cupped in the hand† which are sources of enjoyment for men (and also for women). This rather long stanza goes on to mention other things not only useful to man but handmade by man – keys, salt cellars. This is followed by a description of the intricacies that make up the things stated – the curve of the shoe, the weave, the smokiness of chairs. He does not stop here. He continues enumerating other things that man needs to make life easy and clean and comfortable – spectacles, nail, brooms, clocks, compasses and coins. In the next stanza which is shorter, he marvels at the multitude of pure things has made of wool, wood, glass, rope, tables, ships and stairs. Then the poet waxes sentimental when he remembers feathers, love’s blossoms vanished – glasses, knives, scissors that bear â€Å"finger marks of a distant hand†. It seems that the poet associates these things within easy reach with someone else’s hand – probable that of the loved one who is no longer around. He writes of them as â€Å"lost in the most forgotten oblivion†. How strange that he banishes them to oblivion and yet remembers them. Is he applying reverse psychology here? Sadly, he looks for objects he loves but does not own in houses, streets, elevators

Marketing - Essay Example To change the image, those in the fashion industry are required to think like the customer by finding presentations that ensure high quality and modern looks for the fashion styles that are being presented (Cachon, Swinney, 2009: pg. 15). The strategic buying of those interested in fashion, as well as the decisions which are made is based on the trend of fashion conscious behaviors that are within society. This is especially high among females who are interested in different looks and styles and which are trying to find an image which can present them most effectively in a given situation. The style includes the shape, fit and the colors that work together to present a specific image (Nam et al, 2007: pg. 102). The fashion conscious behaviors make the celebrity endorsement practical to use. When one can see the celebrity approving the styles and looks, it changes the decisions by consumers while showing the effectiveness of the specific look. Celebrities can be used to communicate a message about the specific style, how effective it is and the quality that the brand maintains, allowing conscious consumers to respond in a positive light. While the general trend with using celebrities is one which produces a positive response, there are also non – practical applications of using celebrities. The main problem which occurs is based on negative information transference to consumers. If the celebrity isn’t regarded as fashionable or has a reputation which doesn’t fit with a specific person, then it can lead them away from the brand. This is not only specific to general attitudes, but is also reflective of demographic differences that are in society. If an older woman wants to buy a brand but finds a celebrity that is focused on youth, then they may not think the brand will fit their style or will have a quality that is negative. The brand meaning can change according to the celebrity and alters based on the impact that the celebrity has in societ y (White, Goddard, 2009: pg. 322). The negative information may include pricing, quality and the overall brand image that fashion conscious individuals are looking for within a given trend. This paper will examine the effects of celebrity endorsement as well as the practical and non – practical uses of having an individual represent a brand name. The hypothesis states that the celebrity endorsement is based on attractiveness and credibility of the celebrity. If this is positive, then it can raise the purchase intention of those who are interested in a brand; however, if it is negative, then purchases will diminish. This hypothesis can be seen in figure 1. Figure 1: Celebrity Endorsement This particular chart shows how there are both positive and negative implicatinos that are based on the celebrity endorsement as well as the conscious of those who are interested in buying a specific product. By creating the correct image, brands can leverage their identity; however, without t his, there isn’t the ability to build a strong reputation among potential customers. Examining the ways in which this works positively and negatively can then help determine how the fashion industry can redefne the way that fashion is presented in given circumstances. Celebrity Endorsement and Communication Processes The first way that celebrity endorsement affects those who are interested in a given product is through the communication processes exhibited through the image. When a celebrity endorses a specific fashion product, it is considered as a

Financial Analysis of Burberry Group Plc Coursework

Financial Analysis of Burberry Group Plc - Coursework Example In relation to the study the company which has been selected is Burberry Group Plc is a British luxury fashion house established in 1856 and listed on the London Stock Exchange since 2002. Its business’s mainline involves the sourcing, designing, manufacturing, and marketing of high-end clothing as well as non-apparel accessories for customer segments including women, men, and children. Customers can reach Burberry products through its diversified distribution network of retail, wholesale, digital and licensing channels operated in the United Kingdom and across the world. In the year 2012, Burberry was ranked the 82nd best global brand in the world with regards to its high operating value and such ranking has been improved for the past few years. Therefore, it is worth studying its financial information to see how its operation has developed causing increasing company’s value. For the purpose of carrying out a financial performance analysis of Burberry, the financial st atements of the company pertaining to the last three financial years have been reformulated (See Appendix). The reformulation of balance sheet reveals the net operating assets (NOA) of the company, net debt, and net equity. On the other hand, the reformulation of income statement has revealed the recurring items and non-recurring or exceptional items in the income statement of Burberry. The income statement has been reformulated in two ways, i.e. full reformulation and basic reformulation. The basic reformulation does not include exceptional or non-recurring items in the income statement, whereas in full reformulation, each and every time has been included in the reformulated income statement. The overall analysis of the income statement for Burberry pertaining to the last four financial years shows that the sales growth declined in 2010 in comparison with 2009, whereas the growth rate showed improvement on consistent basis in 2011 and 2012. The main reason behind this consistency in sales growth is considerable increase in the retail sales of the company in the last two years. In addition to this, as the company is also engaged in the wholesales, there is a insignificant increase in wholesales also noted, which has contributed to the growth in sales revenue to some extent. Reformulated Income Statement (Full) 2012 2011 2010 2009 (Sales growth based on previous financial year) 1.24 1.17 1.07 1.21 As per the reformulated income statement, common size income statements for full and basic income statements have been prepared. Common Sized Income Statement Based on Full Reformulation (Excludes Unusual Items

Gravimetric Analysis of a Chloride Salt

Gravimetric Analysis of a Chloride Salt Rania Williams Nour Wehbe Purpose To discover the amount of chloride in a strange salt, in order to demonstrate regular methods used in gravimetric analysis Theory This equation describes the reaction between silver ion and chloride which results in the product silver chloride. Ag+ (aq) + Cl (aq) → AgCl (s) Silver nitrate is used to precipitate chloride because it gives the best results. AgCl Solubility in water: Silver chloride’s solubility is very low; however the salt is still soluble to some degree. If precipitate is not complete, the results will be very low. Ksp = 1.6 x 10-10 Precipitation occurs in acid to greatly reduce any interference from acid ions. These ions form co-precipitates with silver in acid containing no charged ions. Due to co-precipitates the results would be higher. Also in order for precipitation to occur in acid there needs to be some excess of silver ion at the end of the reaction to reduce the chances of silver chloride becoming more soluble. Co-precipitation would result in higher results. Description: The precipitate is heated in order to coagulate it. When it coagulates it will become a clumpy colloidal like form. In this form it will become more difficult for the precipitate to penetrate the filter paper. If the coagulate did go through, the results would be lower. If nitric acid had not been added to the precipitate it would become more vulnerable in penetrating the filter paper. If this had happened the experiment would have to be done again as there would be no way to determine the percentage of chloride in the salt. Photodecomposition: The equation for photodecomposition occurring in the air: AgCl (s) → Ag (s) + Â ½Cl2(g) When the silver chloride has dried and put into light it will decompose into chlorine and silver. If photodecomposition occurs in air, the results would be low, however if this decomposition occurred with excess silver ion in an aqueous solution there will be another reaction (3Cl2(g) + 9H2O (l) + 5Ag+ (aq) → 5AgCl (s) + ClO3(aq) + 6H3O+ (l)), which will make the results high. How much precipitate is lost by washing with 100ml fresh water? Ksp = [Ag][Cl] x x = x2 1.6 x 10-10 = 1.3 x 10-5 1.3 x 10-5= C/0.10 L C =1.3 x 10-5x 143 mol/0.10 L C = 0.01859 mol/L (0.01859)(0.10) = 0.001859 = 1.810-3 g The precipitate is lost due to the solubility of it. The solubility of the precipitate is very low so not much would be lost, however this still would make the results lower. Ions that may co-precipitate with chloride ion: When precipitation occurs quickly the chances of co-precipitation occurring greatly increases. Anions from some acids may co-precipitate with the chloride ion, forming co precipitates. These co precipitates will alter the results, making them CO32-, OH and NO3 Procedure The code number of the unknown salt that was placed on the station was recorded. This sample was kept for the full duration of the experiment. Using the analytical balance, 0.1175g of the sample was weighed out by difference and placed in a 250ml beaker. The beaker was labeled to avoid confusion between partners. The approximate volume of 0.1 M silver nitrate was calculated using the sample’s mass, 0.1175g. The mass of the sample was multiplied by the percentage concentration of the chloride then divided by 35.5. The result was then divided by 0.1. The result was converted into ml. 5 ml of excess was then added to the result, making the final result and approximate volume of silver nitrate added, 23ml. In the 250ml beaker with the sample, 100ml of distilled water and 1ml of 6M nitric acid was added to the beaker. 23ml of 0.1M silver nitrate was measured out in a 25ml graduated cylinder then slowly poured into the 250ml beaker. The solution was placed on a hot plate then gently stirred. The solution was stirred until it became close to boiling. In order to test for completeness the solution had a couple drops of silver nitrate poured into it to test that the entire chloride ion had been precipitated. The solution showed that it was complete. The 250ml beaker with the solution was then placed into the assigned drawer, to limit its light exposure. Using a piece of soft tissue paper the crucible which had already cooled was weighed, it had a mass of 30.6707. The vacuum filtration arrangement was set up. The solution without the precipitate was slowly poured into the filter. 5ml of 0.1M nitric acid was used for washing the precipitate. After a couple washings the precipitate was also placed into the filter. A wash bottle was used to help any remaining precipitate out of the beaker. The precipitate was again washed with 0.1M nitric acid. The crucible was then removed from the vacuum filtration arrangement. The leftover washings were disposed of. The crucible was washed once again in the vacuum filtration arrangement. The washing (mainly nitric acid) was taken to the T.A. for testing if the precipitation is complete by doing a washing with hydrogen chloride on the nitric acid. The first test showed completeness. The crucible was again latched onto the vacuum filtration arrangement to be washed with 3ml of acetone. The acetone was handed to the T.A. for disposal. The crucible was given to the T.A. to put in the oven for drying of the precipitate. The oven had a starting temperature of 110 Â °C and after 30 minutes had a temperature of 119 Â °C. The crucible was then cooled in the desiccator for 10 minutes then weighed with an analytical balance. The result was recorded. Observations Data tables Sample masses Crucible masses Approximate volume of the liquids and solutions used to was the sample Temperature of Oven Crucible drying and cooling times: Calculations Amount of AgNO3 required (calculated amount + 5mL) (0.1175)(0.55)/35.5/0.1 0.018204225 * 1000mL/1L = 18.204225 18.204225 + 5 = 23.20422525mL 23mL of AgNo3 needed Percentage chloride in sample Uncertainties Relative error Relative spread of the percentage of chloride found 62.06% 56.92% / 59.49% = 0.086401076 * 10 = 0.86401076 ppt = 0.8640 ppt Discussion My results were higher due to the photodecomposition of the precipitate that most likely occurred due to an excess of silver ion in the solution. This was a result of human error, as I waited for the precipitate to cool down I did not leave it out of light and failed to ensure that there was not an excess of silver ion in my solution. My results could also be higher due to any co-precipitates from anions such as these: CO32-, OH and NO3 . The results could have also become higher due to not being washed properly. When washing the precipitate only with 3ml of acetone and 5ml of water this may have been possible. When compared with the actual result, my result was higher. My partner’s results were lower than the real value due to some of her sample being lost during filtration. Sample being lost during filtration is almost unavoidable. Even though she may not have lost a lot of her sample, her initial salt mass was just 1.002g. Losing sample from a sample that was already so small contributed to her results being lower than the actual value. She also may have not allowed for complete precipitation of the chloride ion, resulting in lower results. During the heating of her solution her precipitate coagulated but there were stills some parts of the precipitate that were very tiny were susceptible of being loss the vacuum filtration. When compared with the actual result, my partner’s result was lower. The average of my partner and I’s results were very close to the actual result, though the average of our results was still higher than the actual result. Conclusion The sample number for the unknown salt is 343. The average percentage of the chloride from two trials is 59.49%, whilst the actual percentage of chloride is 58.81%. The uncertainty for the percentage of chloride for my results was 0.2041 and 0.2430 for my partner. The precision of my results was 5.526%, whilst my partner’s was 3.214%. The accuracy of the results was 0.8640 ppt. References Books: R.C.Burk, M.Azad, X.Sun, P.A. Wolff, Introductory Chemistry Laboratory Manual, Carleton University, Ottawa, 2014-15.

Essay --

The film Eternal Sunshine of the Spotless mind focuses on the interesting topic of memory. The film follows two main characters, Joel and Clementine, who have both chosen to erase part of their memory. What both characters, and other characters in the movie, find out though is that our memory is complex and very flexible to what we make of it. The film reflects the tendency that we have as humans, to think that we are in control of our memory. The truth is that our memory is not like a video tape of the events in our lives nor is it a library of the knowledge we have collected. As I watched the movie, I couldn’t help but think; our memory is more like a ball of clay. Our minds can take the clay and make it into a shape and we can stare at that shape and know that shape but our minds will play with that clay and mold it into something different eventually. The idea portrayed in the movie is that no memory is safe from our meddling minds. The film emphasizes on the power of our long-term memory and our episodic memories. Would we be happier if we forgot about traumatic past experiences? Or are our long-term memories so tangled up with emotions and sensations that our brain is unable to truly let go of long-term memories? The film also looks at the difference between explicit and implicit memories. Although the film plays out in non-linear progression and is somewhat confusing at times, the audience quickly catches on to the plot. Joel and Clementine are in a relationship for two years before finally deciding to break it off. Like most couples, the two shared a lot of good memories but the fights that lead to their breakup were too emotionally heavy for free-spirited Clementine to bear any more. She pays some futuristic company ... ... to look past all the terrible things in their past and they chose love again. This film challenges the audience to actively get involved with the two characters, Joel and Clem. We see both characters try and take control of their memory. First by undergoing the procedure and then especially when Joel tries to keep his memories of Clem. But the characters find out that memory is more complicated than we think it is. We can mold out memories, change our memories, repress our memories and remember things we didn’t even know we experienced. In some ways, the writers challenge us to think about our own memories. If we were given the chance would we erase some of our painful memories? I think we are unable to detangle our memories. I think that our memories are stacked and tangled with each other and deleting or tampering with those memories is dangerous and unnatural.
