Ethanol: Good or Bad? In the pursuit of a cleaner renewable resource to fossil fuels‚ many scientist have found alternatives. Examples include solar‚ wind‚ biogas‚ geothermal‚ biomass energy and cellulosic ethanol. In the last twenty years‚ efforts have been made to reduce our dependency on foreign oil and ethanol has been an option. Ethanol is nothing new; in fact‚ it was first used in a motor built by Samuel Morey in 1826 (Ethanol History). Since the 1980s‚ the government started having oil companies

Although ethanol has provided our world with many benefits‚ there are also many drawbacks as well. Because ethanol is manufactured from corn crops‚ the value of most corn is higher in costs. This drawback plays a role not only in the world of energy but also in the food industry‚ thus overall impacting our economy. In addition‚ the corn also requires a large quantity of land in order to produce enough material for the ethanol. Farm land is very scarce and difficult to come by‚ because of the constant

stress that various alcohols have on biological membranes. Using five solutions of differing alcohol concentration for each of the three alcohols; methanol‚ ethanol‚ and 1-propanol and a small slice of beet‚ the stirred solution was placed into a plastic cuvette and then into a spectrophotometer and the absorbance of alcohol solutions were determined in order to conclude which alcohol and concentration of alcohol had the greatest effect on biological membranes. The results showed that the most non-polar

Membrane Processing MEMBRANEFILTRATION A membrane or‚ more properly‚ a semipermeable membrane‚ is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Membrane filtration enables to separate particles with a diameter smaller than the pore diameter in the membrane from the liquid feed‚ by applying a driving force (pressure) over the membrane. The membrane technology consists principally of Microfiltration (MF)‚ Ultrafiltration

substrate to form product. Because of the feature of active site‚ each kind of enzymes therefore is specific for a particular reaction. However‚ there are several factors affect the rate of enzyme reactions‚ they are temperature‚ pH‚ concentration of enzyme‚ concentration of substrate and inhibitors. High temperature and pH affects the structure of enzyme‚ irreversible denaturation occurs‚ the shape of active site is changed‚ enzymes therefore no longer function. The effect of the other factors is

Three membrane samples of different thickness (0.1‚ 0.2‚ 0.3 cm) are used as the porous media. The determination of the permeability is carried out using elevated pressure test. Each sample is tested for 5 times at different values of pressure gradient which are 5‚ 10‚ 15‚ 20 and 30 psi. In order to obtain more accurate data‚ ensure that the membrane samples

Connective Tissue As the name implies‚ connective tissue serves a "connecting" function. It supports and binds other tissues. Unlike epithelial tissue‚ connective tissue typically has cells scattered throughout an extracellular matrix. Loose Connective Tissue In vertebrates‚ the most common type of connective tissue is loose connective tissue. It holds organs in place and attaches epithelial tissue to other underlying tissues. Loose connective tissue is named based on the "weave" and type
