Hydropower Plants Work? Hydropower is the combination of head and flow. The Head is water pressure created by the difference in elevation between the water intake and turbine, expressed as a distance (feet or meters) or as pressure (pounds per square inch). Similarly, flow is the quantity of water, expressed as volume per second or minute (gallons per minute, cubic feet per second). In a typical hydropower system, water is diverted from a stream into a pipeline, where it is carried downhill and…

4.1 Strength of Anisotropy “The strength of anisotropy is calculated by the “kern and Richter” formula which gives the magnitude anisotropy k= (Vmax –V min)/Vmean, where Vmax and Vmin are maximum and minimum velocity. For P wave in the olivine crystal Vmax and Vmax are 9.89 and 7.72km/s respectively, so strength of anisotropy is 25%. For S wave k= 22% for Vmax and Vmin are 5.53 and 4.42 km/s respectively” [Seth stein 2003]. This anisotropy is the intrinsic anisotropy of the material defined as…

Cooking with oils can be considered as one of the most common cooking techniques around the world. Within the process of cooking, heating with high temperatures is often applied to break down large polymeric food molecules and for easier absorption of nutrients by our guts. However, heating oil repeatedly with the presence of air, for certain period of time, might cause undesired chemical changes within the chemical characteristics of the oils, for example lipid oxidation, which is responsible…

Introduction: Water and soil, are vital resources. In the arid region, they are experiencing a high degradation in quantity and quality by water erosion. the latter is a natural phenomenon, that evolves with the anthropic evolution and the climate severity, recent studies on the vulnerability to climate change in the Mediterranean region, indicate a trend towards increased aridity which accelerating water erosion (Berkane and Yahiaou 2007; Souadi 2011). Soil erosion by rainfall and runoff is a…

Linum usitassimum is an annual herb belonging to the family Linaceae. The plant is indigenous to west Asia and the Mediterranean. Seed oil of this plant used commercially in the painting and varnishing due to its polymerization properties when exposed to the air and sun light. It is also used as an astringent in fungicidal lotion and an insecticide. Seed oil are reported to rich in essential fatty acids like omega-3- fatty acids (linolenic acid, 35-67%), omega-6- fatty acids (linoleic acid,…

and from onshore overhead electric transmission lines 4) Why Oscillating Water Column? There are a number of factors concerned with the installation of the type of ocean wave energy converter. However, the OWC is chosen as one of the optimum measures to tackle the issue of wave energy conversion. The considerations of which are listed below (16):  There are very few moving parts;  There are no moving parts in the water;  The concept is adaptable and can be used on a range of collector forms…

sting someone in the water. However, when analyzing the science behind the method as to how they sting it wouldn’t seem obvious that they are able to sting outside of the water. Yet, we know that jellyfish can sting outside of water, regardless if they are still living. Ultimately, the question can be posed, “How do jellyfish sting outside of water?” There was once a story that came from a beach in New Hampshire where over 150 people were stung by something in the water.…

polyphenol oxidase (Faisal. S et.al, 2013) which influence in the oxidative activity when the potatoes are cut causing it to become brown in color (Vitti M.C et. al, 2011). Potatoes are not encouraged to be sun-dried as the slow process of removal of water will induce the growth of fungal on the food's surface (Faisal. S et.al, 2013). Blanching treatments or osmotic dehydration method where the highly perishable foods such as fruits and vegetables or in this case, potato, are immersed in the…

Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. Haines’ research paper studies the change that occurs in the FePO4 structure as it is studied from temperatures 294K to 1073K. A transition is noticed at 980K, when it’s tetrahedral α-quartz structure experiences high pressure levels, changing the structure to β-phase, a more dense octahedral structure. Cell parameters of FePO4 in α-phase increases in cell parameters and volume as…

Two chromatographic methods were developed for the assay of the FDA approved lozenges containing dextromethorphan hydrobromide (DXT) and menthol (MNT). The first was a green HPTLC method which depends on using Merck HPTLC aluminum sheets of silica gel 60 F254 and methanol-ammonia (10:0.1, v/v) as mobile phase. This was followed by densitometric measurements of the spots which were retained at 0.28 ± 0.01 for DXT and 0.76 ± 0.02 for MNT scanned at 210 nm. The method was found linear over the…
