"Silk Roads or Steppe Roads? The Silk Roads in World History" The main focus‚ or thesis‚ of this article was similar to the likes of Andre Gunder Frank and Barry Gills; that the trans-civilizational and‚ less understood‚ trans-ecological exchanges along the Silk Road linked all regions of the Afro-Eurasian landmass- agrarian civilizations‚ the woodland communities to the north and steppe pastoralists- into a single "world-system" of trade that is several millennia old. Among these exchanges across

Vitamin C –A Natural Antioxidant Concept: Vitamin C (ascorbic acid) is an antioxidant. The amount of vitamin C content in food can be found out by titrating with an oxidising agent‚ e.g. iodine. In the reaction‚ vitamin C is oxidised‚ while iodine is reduced to iodide ions. The endpoint is determined by the formation of blue-black starch-iodine complex when all vitamin C is oxidised and excess iodine is free to react with the starch solution added as indicator. Introduction Vitamin C is an important

The C programming language (often‚ just "C") is a general-purpose‚ procedural‚ imperative computer programming language developed in the early 1970s by Dennis Ritchie for use on the Unix operating system. It has since spread to many other operating systems‚ and is now one of the most widely used programming languages. C also has had a great influence on many other popular languages‚[1] especially [[C++]] which was originally designed as an enhancement to C. It is the most commonly used programming

CHEMISTRY 221 LABORATORY�QUANTITATIVE ANALYSIS EXPERIMENT: DETERMINATION OF ASCORBIC ACID IN VITAMIN C TABLETS THEORY: Ascorbic acid‚ C6H8O6‚ MM = 176.13‚ can be oxidized to form dehydroascorbic acid by bromine via the following reaction: The bromine or iodine used in the titration is generated by adding an excess amount of KBr or KI to an acidified solution of the sample according to the following reaction: BrO3- + 5 Br- + 6 H+ 3 Br2 + 3 H2O IO3- + 5 I- + 6 H+

orange juices‚ and we also used 0.1% of vitamin C solution. The aim of our experiment was to see how much DCPIP was needed to be added to make the orange juices turn back to the orange colour and the DCPIP to decolourise once the 0.1% of vitamin C was added. DCPIP is a blue dye in its non-reduced form; it becomes colourless when it gains electrons. Vitamin C is an anti – oxidant‚ this is found mainly in fresh fruit and vegetables. The main use of Vitamin C is that it neutralises free radicals‚ which

Hepatitis C 12/02009 By: Shuntrice Hannah Abstract Hepatitis C is an infection of the liver caused by the hepatitis C virus (HCV). It is difficult for the human immune system to eliminate the virus from the body‚ and infection with HCV usually becomes chronic. Over decades‚ chronic infection with HCV damages the liver and can cause liver failure in some people. The hepatitis C virus is transmitted mainly by contact with blood or blood products.

(a) a = 88‚ d = 11. (b) a = −29‚ d = 9 (c) a = 58237‚ d = 58168 (actual question is a = 58237‚ d = 58168 ) Solution: (a) Because 88 = 11・8 + 0‚ we have q = 8‚ r = 0. (The fact that r = 0 says that 11|88.) (b) Because −29 = 9・(−4) + 7‚ we have q = −4 and r = 7. (Note that although we can write −29 =9・(−3) + (−2)‚ we cannot use −2 as r because r is not allowed to be negative.) (c) a = d(q)+r 58237 = 58168(1) + 69 Quotient = 1‚ Remainder = 69 (c actual) We do not need
