2004:85). Research Design The researchers used quantitative research design which is an objective‚ and a systematic process for obtaining information about the laser light activated alarm. The researches used this kind of research design to test past theories about the efficiency‚ effectivity and usefulness of the laser light activated alarm. Determination of sample size The researchers had a total of 20 respondents‚ consisting of 4 respondents from different sections which are all in 4th Year High

Adventures of Zircon and Carbon Zircon and Carbon were brothers from the Triangulum Galaxy. They are two twin aliens that stood 6’7 and were a stunning color of mint green. They traveled 2.7 light years to get to Earth for a special mission. The mission was currently unknown. They were rushed on to a spacecraft and only sent with coordinates and supplies to lead them along the way. The coordinates they had read “Latitude: -64.15164‚ Longitude: -10.58414‚ Distortion: 5.26.” The spacecraft finally

How a faster pulse rate after exercise affects the amount of carbon dioxide in breath and how males and females pulse rates change or don’t after exercise Introduction There is a chemical reaction that takes place in this lab‚ O2 + C6H12O6 –> H2O + CO2 + ATP. This represents cellular respiration‚ the reaction. The reactants are Oxygen and Glucose. The products are water‚ carbon dioxide‚ and ATP. This reaction is split into 3 stages‚ the Glycolysis stage‚ the Krebs cycle‚ and the Electron Transport

polluting the environment because greenery add oxygen to environment filters the air. Atmospheric pollution as a result of emission of carbon monoxide‚ Sulphur oxides and hydrocarbons has become a subject of growing concern and has led to increasing pressure for restrictions of burning of fossil fuels. It is estimated that currently more than 20 billion tons of carbon dioxide are being released in the atmosphere in this way every year. The discharge of these air pollutants is infecting and destroying

Recrystallization Abstract: Technical grade aniline was reacted with acetic anhydride to give acetanilide a dark brown color‚ due to the presence of impurities. Crystallization of the crude product from water was combined with decolorization with activated carbon‚ furnished pure acetanilide as white flakes‚ melting point 112-115°C‚ yield 70.3%. Experimental: 2 grams of technical grade aniline and 15ml water were placed in a 125ml Erlenmeyer flask. Then‚ 2.5ml of acetic anhydride was added while

dose in large amount is less effective than multiple doses in small amount (Pegg & Shahidi 2000). The carcinogenesis of N-nitrosamines requires several steps shown in figure 1. As N-nitrosamines are biochemically stable‚ they firstly need to be activated to form alpha-hydroxynitrosamines. This is done by cytochrome P450-dependent

List of the First 20 Elements and their Physical Properties Atomic Radii (pm) of the First 20 Elements: - Atomic radii decreases when moving down a period‚ as the number of protons increases‚ which thence increases the effective nuclear charge. - Atomic radii increases when moving down a group‚ as the number of shells increases‚ which thence increases shielding. - The downward-sloping pattern on the above graph shows the decrease in atomic radii down a period‚ and the sudden jumps

Abstract This investigatory project determines the possibility of purifying used cooking oil using sedimentation method. The activated carbon was also used in the experiment to absorb some dissolved substances in the oil. There were three different setups used in this study namely; Setup 1 (sedimentation was done once); Setup 2 (sedimentation was done twice); and Setup 3 (sedimentation was done thrice). The purified oil was compared to commercial oil in terms of color‚ odor‚ and clearness using

intracellularly accumulated in the form of intracellular granules and stored in response to an environmental stress or nutrient limitation as a reserve of carbon‚ energy‚ and reducing power (Li et al.‚ 2014). Under the conditions of carbon source starvation‚ PHAs are degraded by intracellular depolymerases and subsequently metabolized as a carbon and energy sources (Singh et al.‚ 2013). Structurally‚ R-hydroxyalkonic acids act as the monomeric form of PHAs. The structure of PHAs‚ composed of 3-hydroxy
