Blood Gas Analysis at the Core Laboratory at University Hospital‚ London‚ Ontario. Blood is one of the most important fluids in the human body. It helps carry nutrients such as oxygen to the cells in the body and transports out wastes like carbon dioxide and other metabolites from these cells. Since blood is the medium through which the different organs and tissues in our body communicates‚ keeping a close eye on the constituents of a blood sample would provide a good indication of the functioning

1. Background knowledge/theory: Nitrite can be produced through a bacterial reduction from nitrate. This reduction can occur in the oral cavity of humans. Nitrate is commonly found in fertilisers for food crops so it’s also found on the outside of fruits and vegetables (Mygind‚ 1991). This is relevant because nitrite can have consequences for our overall health. It can react with secondary amines to form nitrosamines. Research has shown that some nitrosamines can cause cancer (Mygind‚ 1991). Furthermore

Throughout history‚ great world structures depended on the extraction of mined materials. Early civilizations depended upon sheer labor to extract these materials. This was shown to be very labor and time intensive. Especially early on when stone tools were the only thing available. The solution to this problem came in the late 1800s with the invention of dynamite. Gunpowder is considered the first explosive to be discovered. It was first discovered many years ago in China and India. Early uses of

Phosphorus is an essential macro-nutrient for plant growth and sustainable soil management. Phosphorus nutrition can be challenging in acidic soils (e.g. Queensland) and alkaline soils (e.g. South Australia). To achieve sufficient nutrition‚ the soil needs to have a relatively high pH‚ high organic matter content‚ and moist conditions. Specific soil orders such as Vertosols‚ Kandosols‚ Sodosols‚ Rudosols‚ and Calcarosols‚ lack the requirements for phosphorus nutrition. The availability of phosphorus

The electron transfer reaction between hexacyanoferrate (III) and sodium borohydride resulted in the formation of hexacyanoferrate (II) ion and dihydrogen borate ion which was strongly catalyzed by AuNPs. The redox reaction is described as BH4- + 8 [Fe (CN)6]3- + 3H2O 8 [Fe(CN)6]4- + H2 BO3- + 8H+ The advantage of hexacyanoferrate ion for this redox study is that both oxidation states of iron (+2 and +3) are quite stable with respect to dissociation and hydrolysis

CHEM 17 Expt.2-Coupled Reactions 4/18/12 Results and Discussions: One way to obtain products from a non-spontaneous process that is exhibited in this experiment is by “coupling” two reactions. The principle of Coupled Reactions is based on a simple concept: we can use a thermodynamically favorable (spontaneous) reaction to drive an unfavorable one. One step is allowed to supply enough free energy for the other to occur. A coupled reaction is a system wherein a non-spontaneous
