You already know your pool has a pump, but do you really know what that pump actually does? You might be surprised! What Exactly Does a Pool Pump Do? Your pool pump is the heart of your pool and without it, it would die...so to speak. Just like a human heart, your pool's heart (the pump) only has one thing it has to do which is pump water. However, that one thing serves several very important functions, such as: • Pulls the water from your pool through the skimmers and drains. • Then it…

The synthesis of Aa-g-poly(MAA) involve the optimization of various reaction conditions like initiator concentration, monomer concentration, crosslinker concentration, solvent concentration and pH. After the optimization of various reaction parameters the replications were carried-out in triplicates for the reproducibility of the results and statistical of the results obtained. It was performed using the Statistical Package for Social Science (SPSS) version 10. Statistical results of the…

The purpose of this study was to investigate the effect of a system that automatically adjusting hydrogen peroxıde Colloıdal-Ag dose to reduce colonization and growth of heterotrophic bacteria in dental unit waterlines and wastewaters. Thirty dental units were assigned into three groups with respect to the protocol employed: Group 1: 10 units were selected for automatic administration. Group 2: 10 units were selected for manual administration and Group 3: 10 units served as controls. Water…

Water quality dynamics in an urbanizing subtropical estuary (Oso Bay, Texas) Estuarine environments like that of Oso Bay in Corpus Christi, Texas are subject to fluctuations in geochemistry and relative water quality based on factors related to extreme weather events, changing water flow and human impacts. A 2011-2015 study on the water quality dynamics of Oso Bay found fluctuations in the estuarine geochemistry were related to some of these factors, particularly human influences. A wastewater…

combined with an organic mixture of CHCl3/MeOH, to isolate the lipid layer. By centrifuging the organic solvent with milk the heavy lipids sink to the bottom while the water layer which contain water soluble carbohydrates, peptides and small amino acids float to the top. Since the organic solvent had low boiling points the lipids from the organic layer were easily obtained by evaporation. Methods Refer to page 1.2-1.3 in the BCEM 341 Manual Lab 1: Lipids. [1] Results Refer to the attached…

the temperature at a range between 25-55 °C (Pasupuleti & Braun, 2010). During alkaline hydrolysis of proteins, some amino acids like serine and threonine are damaged during alkaline hydrolysis, however, tryptophan remains intact. Also, this process causes racemization of amino acids, by modifying its structure and converting L-amino acid in its isomeric forms D-amino acids (Wisuthiphaet & Kongruang, 2015). Disulphide bonds are also fragmented with loss of cysteine, serine, and threonine and…

One of the parameters that determines water quality is pH. It is defined as the negative logarithm of the hydrogen ion and is intended to be a measurement of the balance of acids and bases. Temperature affects pH. In pure water, a decrease in pH of 0.45 occurs when temperature is increased by 25°C [11]. There are several methods for measuring pH. The most common is the use of a glass electrode sensible to it, a reference electrode and a measurement device. Another method is the use of…

The purpose of this experiment was to learn techniques to determine the freezing point of a pure benzophenone, a solvent. Furthermore, methods for determining the freezing point depression in relation to the solute, cyclohexanone, concentration were employed in addition to learning what molality is and how it related to the colligative properties being studied. These objectives were achieved by melting both pure benzophenone and benzophenone/cyclohexanone solutions (two solutions with…
