Fighting Corruption through Making Music :: Essays on Corruption
Fighting Corruption through Music Singing about corruption is not a new thing and can be described as a disease one can compare with HIV/Aids as been the second most popular in Africa. Thus many see it as the most main cause of many African states slowness in terms of stable economic growth .It is therefore no secret to many ordinary citizens you who keep wondering or face with the dilemma as to how really their governments are operating .As such life in relation to economic growth during and after post colonial rule as always been a litmus test. Sierra Leone The name meaning (Lion mountain) from a Portuguese sailor ?Pedro da sentra also this beautiful diamond shaped country was used by then British colonial masters to settle free slaves thus the capital city was named Freetown .With so many minerals and other resources combined with already many IMF loans been given many see it as been far enough to have change the deplorable living standard of many of its citizens forty years after independence. It is therefore no surprise to many n view of the present governing authorities lack of transparency and willingness to prosecute or crack down hard on those they found in corrupt practice , the faith of many citizens on the Anti-corruption commission been set up is nothing to go by. State of the music industry The music Industry has dramatically grown in the last couple of years despite harsh conditions faced by musicians and composers alike. For many music is sacred , thus it can calm the troubled mind and bind the wandering sense. As such , Sierra Leone during the past years has produced some distinct traditional musicians such as: John Gbala ,Amy Kallon. , Salia,, Rogers(Rogie),Ebenezer Calender and many more.As old musicians continue to rebirth themselves and young musicians continue to see the music industry gaining its reputation , there is now arrays of musicians in categories such as : R&B, POP, traditional , Reggae and religious music. Level of Censorship The level of censorship on music is always a big question whenever musicians produced songs about sensitive issues such as ?

Chemistry Questionnaire Essay
What is meant by the term cis-trans isomerism? How many cis-trans isomers are present in Structure I? Draw any 2 possible cis-trans isomers. (iii) State the physical state of this lipid at room temperature. Explain your answer. [9] (b) Suggest a possible identity for each of the organic compounds A-E below. Explain your reasoning and write balanced equations for the reactions involved where possible. i) A, C11H14O2 is a neutral compound. Hydrolysis of A gives B, C7H6O2 which is a white precipitate and C, C4H10O which does not decolourise acidified potassium manganate(VII) on heating. (ii) D, C4H10O2 reacts with 2 moles of sodium metal, but not with solid sodium carbonate. On boiling under reflux with aqueous potassium manganate(VII), D gives a compound, E, C4H6O3. E reacts with alkaline aqueous iodine to give a yellow precipitate and evolves carbon dioxide when solid sodium carbonate is added. Draw structural formulae of the products of the reactions between glutamic acid and I aqueous NaOH II aqueous HCl (ii) Draw the structural formula of a dipeptide formed between glutamic acid and phenylalanine, showing the ionic form in which it would exist at pH 10. [4] [Total: 20] 5 3 (a) Iron(III) chloride is a dark brown solid which dissolves in water to give an acidic solution. This solution is used to etch, i. e. dissolve, unwanted copper from printed circuit boards. When a copper-coated printed circuit board is immersed in aqueous iron(III) chloride, the solution turns greenish blue. i) Explain, with the aid of an equation, why aqueous iron(III) chloride is acidic. (ii) Use the Data Booklet to explain why iron(III) chloride etches copper. Give a relevant equation to explain the greenish blue solution observed. (iii) Suggest what happens to the overall E0 value if the thickness of the copper coating is increased. Anhydrous aluminium chloride behaves similarly as anhydrous iron(III) chloride in that they sublime readily when heated. When 1. 56 g of aluminium chloride was placed in an evacuated vessel of volume 1. 00 dm3 at 1800C, the pressure produced was 32. kPa. (i) Calculate the apparent relative molecular mass of the aluminium chloride under the stated conditions. (ii) In the vapour phase, aluminium chloride partially exists as a dimer. Using your answer obtained for b(i), calculate the percentage of the dimer under the stated conditions. (iii) Suggest a reason why the dimerisation process of aluminium chloride is exothermic. 6 (iv) Predict, giving a reason in each case, the effect on the proportion of dimer in the equilibrium mixture if I the pressure is lowered, II the temperature is lowered. MgO(s) + CO2(g) ?H? = +117 kJ mol-1; ?S? = +175 J mol-1 K-1 8 (i) Why does the entropy increase when magnesium carbonate decomposes? (ii) Calculate the standard Gibbs free energy change, ? G? , for the decomposition of magnesium carbonate. Comment on the spontaneity of the decomposition of magnesium carbonate at room temperature. (iii) Assuming that ? H? and ? S? for the reaction are independent of temperature, calculate the temperature at which the decomposition reaction becomes feasible. (iv) Compare the ease of thermal decomposition of magnesium carbonate with barium carbonate. [8] Turn over 4 (d) Suggest a simple chemical test to distinguish between each pair of compounds. For each test, give reagents and conditions, and state what would be seen with each compound. The dissociation reactions and Ka values of carbonic acid are given below. H2CO3 HCO3- + H+ Ka1 = 4. 2 x 10-7 mol dm-3 HCO3- CO32 – + H+ Ka2 = 4. 8 x 10-11 mol dm-3 0. 10 mol dm-3 aqueous NaOH is added slowly to 20. 0 cm3 of carbonic acid and the change in pH is followed and shown below. pH x x B x A x x 10 20 30 40 10 Vol of aqueous NaOH added / cm3 (i) Calculate the initial pH of the carbonic acid, stating any assumptions you make. (ii) Calculate the pH at the first equivalence point, A. (iii) What is the pH at point B? Give a reason for your answer. [6] [Turn over 5 (b) Maintenance of pH is vital to the cells of all living organisms because enzyme activity is influenced by pH. For instance, protection from harmful pH change in the blood plasma is provided by the hydrogencarbonate/carbonic acid system (HCO3-/H2CO3). At 370C, the temperature of the human body, pH of blood plasma is 7. 4. i) Explain, with relevant equations, how the hydrogencarbonate/carbonic acid system regul ates the pH of blood plasma. (ii) Calculate the ratio of [HCO3-]/[H2CO3] for maintaining the optimum pH of blood plasma. [4] (c) Describe two differences in physical properties between transition metals and a s-block metal such as magnesium, suggesting reasons for these differences based on their atomic structures. [3] 11 (d) The oxidation of manganese(IV) oxide in alkaline solution in air produces green manganate(VI) ion, MnO42-. When manganate(VI) is added to a dilute acid, a purple solution and dark brown solid manganese(IV) oxide reforms.

The Challenge Of Religious Diversity - 1379 Words
The Challenge of Religious Diversity in The Twentieth Century There are four blind men who discover an elephant. Since the men have never encountered an elephant, they analyze, seeking to understand and describe this new anomaly. One man grasps at the trunk and concludes it is a snake. Another one examines the elephant s tail and announces that it’s a rope. A third finds one of the elephant s legs and describes it as a tree. And the fourth blind man, after exploring the elephant s side, concludes that it is, after all, a wall. Each in his blindness is describing the same thing: an elephant. Yet each interprets the same thing in a radically different way. In comparison to Eboo Patel’s text, â€Å"Acts of Faith: The Story of an American Muslim, the Struggle for the Soul of a Generation,†Patel focuses on living in a diverse faction full of religious prejudice in a world full of materialistic outlooks. He believes religions should be able to coexist without feeling that one religion is superior than the other. Patel’s i ntentions of pluralism in this text is to provide insight on how all religions should coexist, in that manner, I believe that Patel uses logos in the form of his experiences and also the things that he conveys for his argumentative claim of pluralism. His use of logos, in a way that others can relate, makes his claim more effective for those that are reading his book.
