Psychiatry and Clinical Neurosciences‚ 64: 403–407. Basis for the research question in past research and theory: Hypogeusia‚ the reduced ability to taste‚ and dysgeusia‚ the distortion of the sense of taste‚ mainly involving the sour‚ bitter and salty tastes‚ have already been demonstrated in anorexia nervosa patients in literature

However‚ when the interest rate of borrowing from banks is very high due to high inflation‚ together with the stock market is quite instable; calling for capital from bond market is much more preferred by investors. In the context of this report‚ some major points regarding the bond market in Vietnam are presented. Firstly‚ a common picture about the Vietnam bond market is drawn. Next come the types of bonds and major participants in this market. Finally

the amount of light scattered. The scattered light can be used to determine if there is an aggregation of proteins and how stable those proteins are‚ which informs researchers whether there is a ligand binding to the protein or not1. However‚ the point of this lab was to show how light can be used to determine the concentrations of either DNA or proteins in solution‚ which is a very important part of virtual drug screening. This lab introduced how a spectrophotometer can be used to determine the

understand why recycling is a better choice than extracting metal from its ore. Discuss the importance of predicting yield in the identification‚ mining and extraction of commercial ore deposits Yield is the amount of product obtained or in mining terms how much (amount) a particular metal can be extracted from an ore (a deposit of minerals in which a commercial metal can be extracted from). Predicting yield in the processes of identification‚ mining and extraction is vital to the success of a business
