Evaporation

The previous few million years of Earth 's climate has existed controlled by the ice age phases. The ice age phases consisted of extended cold temperature periods with glaciers where massive ice sheets grew on the mainland masses on and around the poles. Because of the ocean water evaporating, the water was being sealed up onto the land as ice. This ice sheet build up has drastically lowered worldwide sea level. Throughout the shorter, hotter, breaks called interglacials, the ice sheets have…

Thales Thales was one of the traditional founders of philosophy. He held the belief that the arche of all is water; water is the core element of all the things that are present. He believed in God and in his writings through Aristotle, Thales portray that the reason why he stated water as the basic element of everything is because the nourishment of everything is moist. One ingredient (water) that is present in all foods might be a factor that contributes to this concept. As for the food that…

Importance of photosynthesis The sun is the main and ultimate source of energy for the planet we live on. Many forms of solar radiation exist but the most important form of radiation in biology and for photosynthesis are infared rays, ultraviolet rays and light rays. Photosynthesis is the way in which some specialised bateria and green plants use their chlorophyll to trap light energy and then use this energy to convert carbon dioxide and water to glucose and oxygen. The green colour in plants…

Mono Sodium Glutamate History: Monosodium glutamate, Most Commonly Called as MSG, is a Sodium Salt (C5H8NNaO4) of the Nonessential amino chemical p and glutamic acid. MSG used as flavour enhancer. it is previously formed by Wheat germs, Which may have 25% glutamic acid, but Coming from mid 1960s it is made by bacteria fermentation of carbohydrates. Seaweed also rich in glutamic acidity and the seaweed remove have flavour boosting properties from the past which is very use full. In 19012…

According to Ahmad S.A. and Lone S.R. “Hybrid Process (Pervaporation-Distillation)”, Distillation is a separation technique, in which a feed mixture of different components is separated into two or more reaction products by collecting the overhead distillate, formed as vapor or a mix of vapor and liquid, and keeping the remaining liquid solution in the reaction container. To achieve this: firstly, the feed has to contain a liquid or a mix of vapor-liquid mixture at the start of the reaction.…

Plant Material Collection Fully grown whole plants of Tribulus terrestris Linn. were collected from different localities of Chennai, Tamilnadu. The fruits were separated out from the plants and washed in running tap water to remove adhering dirt and soil particles and dried first under shade in room temperature and secondly in a hot-air oven for complete drying at 50-60˚C. The dried fruits were made into coarse powder by grinding and stored in labelled bottles for further study and…

The Merriam-Webster Dictionary says that the definition of honor is, “a showing of usually merited respect”, but the dictionary of Sydney Czanstkowski says that honor is earned and not given. Honor is shown to people who truly deserve it. A person who is honorable is someone with good morals, who is honest, and someone who contributes to the common good. To others honor may mean something totally different to them. Veterans, scientists, parents, and teachers can be honorable, it all just depends…

Duckweed. Cup C had the third highest growth rate, which like Cup C was unexpected. Both anomalies (Cup B and C) can be the result of the direct sunlight. Direct sunlight when growing duckweed in small containers (or in this case cups) can result in evaporation of the water which removes nutrients and causes the water to contain a lot of salt which negatively effects duckweed growth as said by Landolt and Kandeler. During the experiment water was evaporated and then topped up, however, it was…

Chapter-III OPERATING PRINIPLE AND LOSSES IN PEM FUEL CELL The polymer membrane is the heart of the PEM fuel cell which has some unique features. It allows protons but it is impermeable to gases, and hence it is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer…

Results and Discussion Shellfish is considered a good indicator for environmental pollution with heavy metals, simply because it can accumulate high levels of these metals. However, these organisms are considered valuable source for animal derived protein, vitamins and essential trace elements, especially for people living nearby sea. Thus, estimating the residual levels of these metals, in particular the toxic ones, assessment of the possible human health risks and trying to find effective…
