3.0 RESULTS AND DISCUSSION 3.1: Effect of Storage Conditions on Egg Weight Tables 1- 2 show the results of effect of storage conditions on eggs weight (chicken eggs and quail eggs). The weight of chicken eggs stored at ambient condition (control), moist sawdust, refrigerator and those that were dipped in oil reduced from 63.61-60.03g, 63.11-60.99g, 61.12-59.41g and 66.12-65.79g respectively. While the weight of quail eggs stored at ambient condition (control), moist sawdust, refrigerator and…

FTIR Spectroscopic Study on Inner Membrane of Egg Shell of Chicken Gallus gallus domesticus Abstract: The paper presents FTIR analysis of inner membrane of eggshell of chicken Gallus gallus domesticus. Fresh samples of egg shells are cleaned; dried and inner membrane of the shell is separated carefully for FTIR analysis. FTIR spectrum reveals a series of bands related to fats and proteins. Calcium carbonate is the major constituent (about 90%) of the shell, but it is absent in the inner shell…

A membrane is defined as a thin sheet, film, or layer, which works as a selective barrier between two phases that can be liquid or gas.113 In other words, a membrane is an interface between two adjacent phases acting as a selective barrier, regulating the transport between the two components.114 Membranes have gained an important place in chemical technology and are used in a broad range of applications.115,116,117 The key property that is exploited is the ability of a membrane to control the…

5.4. Electrosensitive hydrogels Hydrogel swells in response to an electrical stimulus with a mechanism very similar to pH, experiences shrinkage, and bending. The major difference between electrical and pH stimulations is that the electric field moves mobile ions in order to regulate an ion concentration gradient through the hydrogel and the solution [54,55]. Polymeric networks containing ionizable groups can have important electrical behavior under an electric field. The electrosensitive…

Surfactant Agents I. Definitions a. Surfactant: A surface-active agent that lowers surface tension i. Examples 1. soap 2. detergent b. Surface Tension: Force caused by attraction between like molecules that occurs at liquid-gas interfaces and that holds the liquid surface intact i. Units of Measure: dynes/centimeter (dyn/cm) 1. the force required to cause a 1 cm rupture in the surface film ii. a droplet forms because a liquid’s molecules are more attracted to each other than the surrounding…

Gram seeds embryo is called dicotyledons. Seed germination is the process i which the seed breaks a part and the embryo inside to grow with the help of water and a nutrients from the soil seed normally begins to germinates then they get an appropriate range of soil,temperature and when water and oxygen are available.During germination the seeds absorb water either through the micropyle(pore like opening) it is present or through the testa(outer seed coat) when it is permeable.The entry of…

concentration. The greater the concentration, the greater the rate of diffusion. Also known as the concentration gradient. Another process in which particles enter and leave cells is osmosis which is a kind of diffusion that involves water molecules. This takes place…

In this unit of my 9th grade Physical Science, we are learning and experiencing with labs. In this week's experiment, my class did the paper towel lab. Here, we tested the quality of three different paper towel brands, Viva, Up&Up, and Bounty. Each lab group was testing for a certain quality of each brand, such as strength and absorbency. Through different experiments, each lab group came to the conclusion that one paper towel brand had more strength or better absorbency than the other two. My…

This experiment was centered on diffusion and osmosis. In order to see diffusion and osmosis in action it was required to test three different solutions on an egg: one with sugar, another with vinegar, and the last one with regular water. This would demonstrate certain interactions, and movements of the water; making the different concentrations of water visible. As stated there will be three solutions, this will help answer the question of how each type of solution will individually affect the…

cell. Adding ethanol disrupts much of this. 1. Ethanol is permeable to cell membranes. Because of the nature of ethanol as a chemical is it able to get into the cell very easily. This disrupts the balance of the cells' osmotic environment. Osmosis is the movement of water. Think about what happens if you fill a balloon too full. What happens? It expands and stretches the membrane of the balloon. If you release too much water from the balloon it crumples the membrane…
