the quality of the produced corkboard out of pineapple peelings and leaves comparable to the commercial product when analyzed by strength, appearance, and texture? Abstract The major relevance of this study is to produce alternative materials from recycled things/waste products, fruit peelings for instance to replace our commercial materials which is really expensive in making things to be part of our day-to-day life. Experimental method of research was used. The process involved some phases

M Project Report Israel Sharipo September 13, 2013 Abstract This paper shows the true proportions of M&M candies through the random sampling of 3 different bags of plain M&M 1.69oz bag of candy bought from three different stores. I believed one will be able to determine data analysis and how it works as it relates to our class project. Introduction The rationale of writing this paper is to show how

membrane in the cylinder shaped agar. Procedure two: The water diffuses away from the NaCl solution in every scenario, leading to the conclusion that it has the highest water potential of the solutions tested. Because a greater proportion of water diffused away from the sucrose than the glucose, it can be hypothesized that the sucrose has a lower water potential than glucose. Because water diffused to the glucose and away from the 5% ovalbumin solution, we can also hypothesize that the glucose has a

biochemical tests is to identify the unique traits it yields and with that knowledge we can then categorize them in groups and specify them by scientific name. These experiments included the Triple-sugar iron agar (TSIA), Sulfur Indole Motility (SIM), Methyl Red (MR), Voges-Proskauer (VP), Citrate, Urease, Gelatin, and Oxidase Test. In order for these tests to produce reliable and credible results, the bacterium organism must be grown using strict and meticulous procedure to produce viable colonies of pure

safety of our health and to avoid the negative effect in the plants and organisms that balance the organisms. Upon trying many colors of light waves, we have proven that the red and blue colors have the greatest impact on the plant growth, while the green light appear to be the least effective because it only gives color green to the plants. We need to follow the correct process on how to use the light waves or otherwise, we can’t make this experimentation to be successful. Acknowledgement This

the carbonyl group. Reactions that occur because of the presence of the carbonyl group include nucleophilic addition reactions and base catalysed condensations. Aldehydes are also easily oxidized, which provides a convenient means to distinguish them from ketones. The carbonyl group in aldehydes and ketones is highly polarized; the carbonyl carbon bears a substantial partial positive charge and is susceptible to nucleophilic attack. Further, since it is sp2 hybridized it is relatively open to attack

their own local community. And show people that it is going to be immediate, this is not something in the future, its going to be happening in some years’ time. We heard a lot about setting up targets, and people always think the target is quite far from them and they think it can be sorted out then actually that is already too

The bright dancing lights that appear in the sky are called the Aurora Borealis . These lights are made of from collisions of electricity charged particles from the sun entering at earths atmosphere . The lights are seen above the magnetic poles of the northern and southern hemisphere. Auroral displays appear in many colors although pale green and pink, shades of red, yellow, green, blue, and violet have been seen and reported . Some of the lights appear in many different forms of patches or scattered

Oxidation) which gave a positive result by producing a blue-green solution with the sample n-butyl alcohol, acetaldehyde, benzaldehyde, and isopropyl alcohol. 2,4-Dinitrophenylhydrazone (2,4-DNP) was used to detect presence of carbonyl groups. In this test, only acetophenone gave a red-orange precipitate. The tests to identify between aldehydes and ketones are Fehling’s test and Tollen’s Silver Mirror test. In Fehling’s test, it gave a brick-red precipitate in n-butyraldehyde and benzaldehyde; while in

Enzymes are biological catalysts that carry out thousands of chemical reactions that occur in living cells. Most of them are proteins. They speed up metabolic reactions in the body but remain chemically unchanged themselves In the experiment, the enzyme amylase was involved.this enzyme takes part in the digestion ofcarbohydrate. digestion is the break down of large complex and insoluble food into small simple soluble molecules for the body to absorb it. starch is a complex, the body have to
