Photovoltaic technology directly converts solar energy into electricity. Photovoltaic thin film solar cells are easy to handle ‚ inexpensive and also easy to use. Thin film panel is flexible and can tolerate a bullet hole without failing and can greatly increase the surface area and the absorption coefficient needed to generate electricity. This paper will discuss the advantages and disadvantages of the thin- film solar cell and also describe its application and how its work. Introduction: The

“Carbohydrates in our Life” The cells are composed of biomolecules that are needed in order for us to live‚ one of which are carbohydrates. Most people tend to think that carbohydrates are fats but that is not the correct way of thinking about it. Truthfully‚ these are all just fallacies. In fact‚ carbohydrates or in scientific terms called as “saccharides” serves as fuel and energy storage in our body. It can either be classified as simple or complex and is composed of carbon‚ hydrogen and oxygen

“Brilliant. Vertiginously exciting…vibrantly imagined. An achievement of extraordinary depth and beauty of the natural world.” –Raul Dagmar Into Thin Air is based on a true story seen through the eyes of Jon Krakauer. He is a journalist and mountain climber who decides to climb the treacherous Mount Everest and joins the most disastrous expedition in history. Krakauer mixes in with the climbing service called Adventure Consultants‚ which is guided by Rob Hall who is also responsible for the lives

Pre-lab 1: Identifying Carbohydrates Abstract The point of this lab is to determine if a substance contains carbohydrates such as a reducing sugar and/or polysaccharides. This will be done by using Benedict’s reagent and Iodine stain tests. Benedict’s reagent will react to reducing substances in the solution by oxidizing it and changing the structure of the reducing sugar to form a colored precipitate. The color of this precipitate can be used to determine the concentration of reducing sugars in

Cell membranes are a bilayer make up of phospholipids‚ proteins‚ and cholesterol. Its main function is to regulate what comes in and out of the cell by means of diffusion‚ transport proteins and protein channels. Trans membrane proteins transport polar solutes across hydrophobic regions of the bilayer. Diffusion occurs when solutes are transferred from a high concentration of that solute to a lower concentration of solutes. Solutes do not depend on the concentration of other solutes‚ which allows

Without a good supply of carbohydrates as glycogen in the muscles and liver‚ and frequent supplies with food and drink‚ it reduces the amount of time that can be sustained a moderate or intense physical effort. Who takes part in events that last for over an hour must pay particular attention to supply meals and snacks rich in carbohydrates. Dehydration impairs performance and athletes should not lose more than 2% of body weight during
