Investigating the effects of carbohydrates on blood glucose levels INTRODUCTION There are two types of diabetes which includes diabetes inspidus however the disorder most commonly associated with the generic term ‘diabetes’ is diabetes mellitus. Diabetes mellitus is condition whereby blood sugar levels are far too high due to poor metabolism. There are two variations of the disorder which are Type 1 and Type 2 Diabetes Mellitus. Type 1 diabetes occurs as a result of the body’s inability to produce

Gas chromatography is the common method used for the biogasoline analysis. Biogasoline catalytic cracking process requires detailed qualitative and quantitative analysis of the hydrocarbon composition of its oil and fraction. In this analysis‚ their fractional composition‚ saturated vapor pressure‚ density and antiknock rating will be investigated. By knowing the qualitative and quantitative composition of the gasolines‚ the content of n-paraffin‚ isoparaffin‚ aromatic‚ naphthene‚ and olefin (PIANO)

Mount Everest is one of the great wonders of the world and widely used for extreme mountain hiking.Only the most motivated and most fierce people can make it to the summit of Mount Everest.The infamous mountain is known as the tallest‚greatest and a test to humankind‚but is it getting too risky.On April 18‚an avalanche caused a destructive lost of 16 lives.Thirteen bodies were recovered within two days and the next-of-kin were paid $10‚000 insurance and and token sum from the Nepalese government

The materials used for this lab were filter papers‚ a choice chamber‚ eight pill bugs‚ water‚ and tin foil. The first step of the process is to trace and cut the filter paper so it fits neatly within each side of the choice chamber. Then‚ put water each filter paper and place the damp filter paper into the choice chamber. The damped filter paper causes the pill bugs to not be able to crawl under the paper and therefore disrupting the results. Four pill bugs should be placed on either side and one

The 7 layers can be split logically into two subgroups. Layers 7 thru 4 focus on the end to end communication of data source and destinations. Layers 3 thru 1 are provide consistent communication between the network devices. An easier way of looking at the OSI model is dividing the upper layers (7‚ 6‚ 5) from the lower layers (4‚ 3‚ 2‚ 1). The upper layers deal with application issues and are implemented only in software. The highest layer‚ the application layer‚ is the closest to the end user

Fischer Esterification – nucleophilic substitution reaction Strong acid catalyst (concentrated sulfuric acid Purpose of a reflux is to heat a reaction mixture at its boiling temperature to form products‚ without losing any of the compounds in the reaction flask TO HAVE GREAT PERCENT YIELD: As reaction is reversible‚ removal of water or the addition of an excess of one of the reactants (cheaper one) drives the reaction towards formation of ester. (Excess carboxylic acid is used) Adding excess

Cfcs Cause Deterioration of the Ozone Layer The deterioration of the ozone layer ‚ caused by Cfcs‚ endangers the lives of humans ’. Cfcs have a diminishing effect on the ozone layer. Furthermore‚ the deterioration of the ozone cause an increase of Ultraviolet (UV) radiation which can have a negative effect on human skin and eyes. As a writer for newsweek‚ I have investigated the scenario and found the following information. The earth ’s atmosphere is a blanket of air that surrounds the planet
