According to the kinetic molecular theory, gas particles are constantly in motion just like other forms of matter. However, their movement is distinct in that it is characterized by random translation. In solids, the particles primarily undergo vibrational motion. In liquids, they mainly vibrate and rotate, and also experience some translational motion. Gas particles move…

Jerzy Konorski (1948) first defined ‘Neuroplasticity’ as the capacity of brain for reorganization in response to the environment. How much is the brain capable of rewiring? And does it retain its plasticity throughout a man’s life? Recent findings reveal that brain indeed possesses anatomical and physiological mutability early in man’s life and aging has been…

Distillation is defined as a process in which a liquid or vapor mixture of two or more substances is separated into its component fractions of desired purity, by the application and removal of heat. Distillation is the most commonly used separation process in the chemistry and petrochemical industry, mostly employed in continuous processes but also…

Introduction The Lesch-Nyhan syndrome is a rare, genetically inherited disorder first described by Michael Lesch and Willian Nyhan in 1964 (Nyhan et al., 2007). It affects males, and is present immediately after the child is born. The prevalence of the disease is of about 1/100,000 of live births worldwide, with around 1/380,000 in Canada and in…

Carbohydrates are molecules that are synthesized from carbon, oxygen, and hydrogen atoms. Some types of carbohydrates consist of a single unit consisting of a few atoms, while other carbohydrates consists of thousands of units linked together through chemical bonds. Glucose, maltose, and glycogen are three carbohydrates that are similar, but structurally different. Carbohydrates have the…

Creatine Information: Creatine is a naturally occurring metabolite found in muscle tissue. It plays an important role in energy metabolism and ATP reformulation. Muscle soreness, lactate buildup, and fatigue are direct results of depleted ATP stores. Creatine replenishes ATP stores, thus prolonging the time to fatigue. Creatine also increases available instant energy, increases muscular strength,…

Before delving into the “gothic” elements found in Melville’s Moby Dick and the short stories of Nathaniel Hawthorne, it may be helpful to understand just what the term “gothic” means in a literary context. While the original “Goths” – a Germanic tribe originating in a region of present-day Sweden still known as Götland – were…

We are first introduced to Virgil Tibbs at a train station, where he sits silently upon a bench marked “coloured. ” He appears to be quiet and shy, and possibly scared of the Caucasian officer who arrests him, but we are soon to realise that there is a lot more to Mr. Tibbs than just…

 Intro/Background In order for oxygen to be present photosynthesis must occur. Photosynthesis takes in light and CA, and through a series of steps produces oxygen. Photosynthesis can be measured by either the disappearance of substrate or the accumulation of product. Examples include the production of 02 or the consumption of CA. All the oxygen within…

The objective of this experiment was to ascertain the reactions of carbohydrates in three tests: Benedict’s test, Barfoed’s test, and Iodine test. Carbohydrates have a vital role in living organisms and primarily contribute to energy production. They are made up of carbon, oxygen, and hydrogen with a ratio of 1:2:1. Carbohydrates consist of three main…
