Effect of temperature and humidity on the transpiration rateof the whole mushrooms P.V. Mahajan * ‚ F.A.R. Oliveira‚ I. Macedo Department of Process and Chemical Engineering‚ University College Cork‚ Ireland Abstract Water loss or transpiration is an important physiological process that affects the main quality characteristics of fresh mushrooms‚such as saleable weight‚ appearance and texture. A loss in weight of only 5% may cause fresh produce to lose freshness and appear wiltedand it is an

Our first essay of Freshman Composition was to write a narrative about something that impacted our lives. I didn’t really know what to expect from this assignment. I knew I could write about my car wreck and give precise details about every little moment. When I started writing‚ I created a mind map to organize all the details. However‚ I was worried about my writing skills. I didn’t know what my instructor was expecting from me in this paper. I have never been a strong writer and that really concerned

molecule is broken down into smaller pieces is called an anabolic reaction. Hypothesis The prediction would be such that as the substrate concentration increases‚ the rate of reaction will go up at a directly proportional rate until the solution becomes saturated with the substrate hydrogen peroxide. When this saturation point is reached‚ then adding extra substrate will make no difference. The rate steadily increases when more substrate is added because more of the active sites of the

MSG or monosodium glutamate is a sodium salt of glutamic acid which can be naturally found in many common foods that are rich in protein content such as dairy products‚ meat‚ vegetable and mother’s milk. In fact‚ our own bodies do produce glutamic acid via Krebs cycle during metabolizing food. Glutamate is the most abundant naturally occurring non-essential amino acid (Ninomiya‚ 1998) and it is a very common part of our diet. In the food industry‚ MSG is widely used as a flavor enhancer. It is responsible

Composition of Concurrent Forces Abstract— The experiment aims to show the relationship of different forces acting at the same time by using different variables namely‚ the equilibrant force‚ the resultant‚ and the given forces Fa and Fb. The equilibrant force is the force that establishes equilibrium while the resultant is the addition of the given forces and is also the opposite of the equilibrant. The objective of the experiment is to determine the resultant of two forces experimentally‚ to
