fermentation are souring of milk curd‚ bread making wine making‚ brewing. The word ‘Fermentation’ had been derived from Latin (‘Ferver’ means to ‘boil’). As during fermentation there is lot of frothing of liquid due to the evolution of carbon dioxide‚ it gives the appearance as if it is boiling. The science of fermentation is known as zymology. Fermentation takes place in the absence of oxygen (when the electron transport chain is unusable) and becomes the cell’s primary means of ATP (energy) production

Unit _ - Control of Air Pollution FABRIC FILTER – It consists of a tabular bag which is closed at the upper end and has a happer attached at the lower end to collect particles when they are dislodged from the fabric. Many such bags are hanged in a bag house. The filter bags are cleaned occasionally by a mechanical shaker for efficient filtration. It has high efficiency and can filter 0.5 µm size particles. ELECTROSTATIC PRECIPITATOR – It works on the principle of electrostatic precipitation

enables them to exchange either positively charged ions (cations exchanges) r negatively charged one (anion exchangers). Many natural substances such as proteins‚ cellulose‚ living cells and soil particles exhibit ion exchange properties which play an important role in the way they function in nature. Synthetic ion exchange material based on coal and phenolic resin were first introduced for industrial use during the 1930s. Results and Calculations The concentration of Ni2+ and Fe3+ ions was to be

about the combination of Aerospace Engineering and Chemistry. I chose this particular topic because of my future life goals. Which include getting a degree in aerospace engineering. I also became interested while researching for this paper in a particular sub topic of the two which is called aerothermochemistry. Aerothermochemistry is the study of gases which takes into account the effect of motion‚ heat‚ and chemical changes. Which is important to the field of aerospace engineering in the fact

“Never give up” When someone says you cannot do something‚ it’s only a better opportunity to prove them wrong. Tearing my ACL was one of the worst days of my life. It was my senior year in high school‚ my last year to prove a point. I was hoping I would be recognized‚ I wanted to show that it was my turn to make something out of myself. I went up for the ball and “WHOMP!” My leg flew forward. I fell to the floor more shocked then in pain. I didn’t know what to do. I called my mom and she rushed

THE WONDERFUL HYGENIC WORLD OF SHAMPOO Everyone who uses shampoo could tell you that their main factors in choosing a shampoo to use are smell‚ look‚ and price. People are misinformed about shampoo and how to tell the difference between a good shampoo and a bad one. The main point of shampoo is to cleanse your skull of residue that is picked up either from hair products such as hair spray‚ gel or moose‚ as well as the dirt in the air‚ and perspiration. Shampoo is something that all of us use on
