Figure 2: Stress- strain graph The stress strain relation dependent on time and time-depending behavior of materials is known as visco-elasticity. This term derived in two expressions: Viscosity and Elasticity, Elasticity is about solid whereas Viscosity resistance to flow in fluids. Therefore, this type of material is a combination of fluid and solid properties which presents a following relation

Simon sometimes tastes or senses the medication in his food and spits them out, but sometimes the medication goes undetected. He always wonders why he feels tired most of the time without doing any activities that may cause such feelings. Covert medication is described by Kala (2012, p. 1) as, ‘the practice of hiding medication in food or beverages so that it goes undetected by the person receiving the medication.’ Latha (2010) states that covert medication is one of the greatest challenges for healthcare

Density Lab: Look at two sample cylinders. Even though the cylinders are the same size and shape, one has a greater mass than the other. Both cylinders are solid and are not hollowed out anywhere inside. 1. Look at the drawing of the copper and aluminum cubes and their atoms. What are two possible explanations for why a copper cube has a greater mass than the aluminum cube? Hint: Just because the aluminum atoms are larger, they are not necessarily heavier. Explanation 1: Explanation

D. Specific Gravity * Procedure: I borrowed a refractometer from the counter and held it in a horizontal position and placed a small amount of urine on the capsule with the support of a dropper, then I looked into the scope of the refractometer to see the measurement of the specific gravity of the urine sample. * After doing the experiment, I threw the urine in the toilet and cleaned the container that I used to put the urine Objectives: -To find the specific gravity of the urine sample

Refraction and Reflection People often wonder why it is that when looking at fish in an aquarium, the fish seems to suddenly change to a different position as we look at them from different viewpoints. What makes Diamonds seem to sparkle so much, or even when a straw is inserted into a glass it looks tilted or at an angle. All of these questions has the same answer and are all examples of Refraction, Refraction is the change in direction of light as it changes speeds passing from one material into

Development and Applications of Acoustic Charge Transport CID #478 Physics 222 Term Paper #1 Abstract Acoustic charge transport is accomplished through the use of a surface acoustic wave passing through a low dimensional electron layer. The power efficiency is increased with a piezoelectric substrate. Quantum wires are formed with higher wave intensity, and quantum dots are formed with the interference of two waves. Such methods have applications in electronics. Excitons are preserved

Motivation is the process of influencing an individual as to act or behave in a certain way. Motivation was defined by Weihrich and Koontz in their book Management A Global Perspective as” a general term applying to the entire class of drives, desires, needs, wishes and similar forces”. (Weihrich and Koontz, 1994, p 462) Motivation can also be defined as “the psychological forces that determine the direction of a person’s behaviour in an organisation, a person’s level of effort, and a person’s level
