Sources of air pollution refer to the various locations‚ activities or factors which are responsible for the releasing of pollutants in the atmosphere. These sources can be classified into two major categories which are: Anthropogenic sources (human activity) mostly related to burning different kinds of fuel • "Stationary Sources" as smoke stacks of power plants‚ manufacturing facilities‚ municipal waste incinerators. Power plant is also used to refer to the engine in ships‚ aircraft and other

Nitration Of Toluene When reacting Toluene with (NO2+) the end goal is to generate an ortho-‚ para-‚ and/or meta-nitrotoluene. This lab will help guide you in the direction to predict the regioselectivity and activation vs. deactivating powers of the nitro-group. Gas Chromatography will be used to analyze compounds that can be vaporized without being decomposed. GC is also used to check the purity of a substance‚ and separating the different components within a mixture. Figure 4: The Nitration of Toluene

What would the world be like if one day technology was inaccessible? Technology is used extensively in the healthcare department to provide patients with the best treatment. This is especially the case at the Mount St. John’s Medical Centre (MSJMC)‚ where technology must be up to date‚ easy to use‚ and designed to aid doctors to make the best and fastest decision with accurate information. Technology is best described as “the practical application of knowledge” or “manner of accomplishing a task”

Chalcones were synthesized according to the previously described methodology (26). A substituted acetophenone (5 mmol) and benzaldehyde (5 mmol) were dissolved in dry methanol (30 ml) and catalytic amount of sodium hydroxide was added to the above solution. The reaction mixture was stirred for 30 min and then neutralized with 1 N HCl. The products were purified by recrystallization from ethyl alcohol and water. The synthetic procedure and reaction conditions for chalcones are illustrated in scheme

We must all now be familiar with the Atkins Diet. Of all of the ’trend’ diets that move through our popular culture‚ none has caused as much interest or controversy. Put forward by the late Dr. Robert Atkins in the 70’s‚ the diet that has caused a storm is continuing to acquire both dedicated followers and severe opponents both within and without the medical community. The Atkins diet itself is only the most popular of an approach usually called low-carb diets because of the primary interest in
