DIELECTRIC The requirements of good dielectric: o Low dielectric loss‚ o High mechanical strength‚ o Free from gaseous inclusions‚ and moisture‚ o Resistant to thermal and chemical deterioration. Solid dielectrics have higher breakdown strength compared to liquids and gases. When breakdown occurs‚ solids get permanently damaged while gases fully and liquids partly recover their dielectric strength. Breakdown mechanism varies depending on the time of application

Many different plant and animal species thrive in the rainforest environment‚ but it is the trees that define the way we see the rainforest. From the air‚ a rainforest looks like an enormous‚ green carpet. The canopy very rarely breaks‚ with no gaps between the trees. Beneath these trees‚ there are thousands of different types of plants. Living amongst the trees‚ vines‚ shrubs‚ ferns‚ and mosses are many different types of animals. These range from the smallest ant to the carnivorous (meat-eating)

However when the Chinese government realised how harmful it was if you were addicted‚ they banned it‚

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

Thursday‚ October 4th‚ 2012 Tuesday‚ October 9th‚ 2012 Comparing Plant and Animal Cells Abstract The purpose of our lab was to have a better understanding of what are the differences between animal cells and plant cells. Although the cell is the basic unit in both living beings they are not completely alike. For that I have examined and compared human cheek cells to Elodea leaf cells. First‚ I’ve scraped the inside of my cheek with the end of a swab stick to collect the cells then I’ve prepared

Could Have In the poem “Could Have” by Wislawa Szymborska‚ she constructs the poem in such a way that she is speaking not to one singular person‚ but everyone affected by the Holocaust. Szymborska writes‚ “You were saved because you were the first. You were saved because you were the last.” I believe this is her way of broadening the horizon of who she is talking to. From what we know about Szymborska and her past careers as a poetry editor‚ a columnist‚ and a translator we can see that right off

The domestication of plants and animals lead to great change in the development and structuring of communities‚ as the hunter-gatherer lifestyle was slowly replaced by permanent settlements of farmers and villages. We can see that the communities varied greatly dependent on their local ecology‚ the resources available‚ and the time period within which their community was based. The road to agricultural way of life in the MIddle East is characterized by Four distinct stages. It was during the Kebaran

of hydrogen peroxide with a fixed mass of catalyst. A catalyst is a substance‚ which alters the speed‚ or rate of a chemical reaction but is chemically unchanged at the end of the reaction. The two factors that we can change are the temperature and the concentration. We chose to vary the concentration of hydrogen peroxide. The catalyst to speed up the reaction without affecting the result will be manganese oxide. Prediction: I predict that the higher the concentration of hydrogen peroxide‚ the
