among the amino acids. Enzymes usually work to complete one specific job which makes them specific catalysts. They also won’t be found all over the body‚ enzymes are found in neural cells‚ intestinal cells‚ and saliva. Enzymes are among the many organic macromolecules‚ they specifically belong to the proteins. Proteins are made of amino acids which link together to be folded into a three-dimensional figure. Enzymes are a different type of proteins because they make chemical reactions happen faster

The present work investigates the mechanical properties and tribological behavior of Al-B4C composites. Attempts were made to overcome the wetting problem between B4C and liquid aluminium at lower temperatures for promising the mechanical and tribological behaviour of the Al -B4C composites. AA6061-B4C particle reinforced composites were produced through casting route at 850ºC with K2TiF6 added as flux to overcome the wetting problem between B4C and liquid aluminium metal. The Aluminium B4C composite

When it comes to organic chemistry and the synthesis of specific products there is an abundant amount of routes that can be taken and still get you the same result. For the following experiment‚ the main focus is the use of a cycloaddition reaction‚ also known as Diels-Alder. According to the lab manual‚ this reaction consists of the addition of a diene and a dienophile and that the Diels-Alder reaction builds stereospecific ring compounds with ease (Weldegirma 80). The reaction takes place between

watched a downloaded movie before it reaches cinema? This is known as media piracy and it is destroying the auratic viewing experience of viewing a film in cinema. In the following essay I will look at the short essay‚ The Work of Art in the Age of Mechanical Reproduction‚ written by Walter Benjamin (1936) and what he means by this ‘aura’ of uniqueness. I will provide a visual example to explain this concept. This discussion will relate to the notion of distance‚ and also how Benjamin (1936) explains
