Determination of the gel-point of a resin via DMA testing and its use in a practical sense The DMA is used to determine the modulus values of the resin to associated temperatures and frequencies. The state of viscosity of the resin is also monitored through the evaluation of tan delta values. Gel-point of a resin implies that resin matrix has transformed into an elastic gel state and can no longer flow. The viscosity shows a sudden rise to extremely high values. The time at which this state is…

Where M.R is the moisture loss ratio, M_0 is the initial moisture content, M_t is the moisture content at time t, M_e is the equilibrium moisture content, t is time (minutes), and a, b, c, and k are constants. For the effectiveness of diffusivity, Fick’s equation was used (5) to estimate the dehydration kinetic of different osmotic conditions. M.R=((M_t-M_e)/(M_0-M_e ))=〖8/π^2 e〗^((-(π^2 Dt)/(4L^2 )) ) …(5) Where D is the effective diffusivity, and L is the length of the (cubical) sample.…

In 1854, Dr. John Snow, devised a map of the London Cholera outbreak. He was known to be one of the founding fathers of epidemiology. During that time period, many civilians were dying quickly and rapidly from Cholera (Frerichs). Dr. John Snow suspected the containment was coming from a well known area like a water pump. Snow obtained data of where the individuals lived and the location of the water pumps and mapped the outcome (Frerichs). The map has many different aspects.First, I will…

Oil and water are two different concepts that are believed to not mix. Normally, when pouring oil into water or vice versa, the two separates instead of mixing. However, when they do mix, both oil and water complement each other. The concept of the three main religions, Judaism, Christianity, and Islam, can be explained through the idea of oil and water. When these religions mix, they create something special. Each religion has two different ways of viewing God even though it is the same God. In…

Glass. In modern times this substance is used as a basic necessity for windows, car windshields, bottles, jars, glasses, dishes, etc. Glass was discovered by Egyptians in the sixteenth century B.C. when experimenting with their pottery. During the fifthteenth century, the Egyptians started venturing into glass vessel making. Later, the Phoenicians and Mesopotamians followed suit by developing a fairly adequate method of glass blowing. To describe glass blowing in brief, glass must first be…

ABSTRACT Flakiness & Elongation index is one of the most prominent criteria that govern behavior and performance of aggregate in the bituminous mixes. The strength and serviceability requirements of bituminous mixture such as Stability, Flow, Voids in Total mix (VTM), Voids Filled with Bitumen and (VFB) highly depend on the physical properties of aggregates. This study conducted by observing the effect of flakiness & elongated index by adding different percentages from 0% to 50% of flaky &…

Oxygen can be delivered by low or high flow systems depending upon the client’s need. Low flow methods allow for room air to be inhaled along with the supplemental oxygen; examples of low flow methods include nasal cannulas, face masks, oxygen tents, and transtracheal catheters. The nasal cannula can deliver 2 to 6 L/minute and is the cheapest most commonly utilized device tolerated well by clients. In addition, the device is easily applied and does not block the mouth allowing the client the…

Steel pressure tanks are very strong as they were designed to withstand a great amount of internal pressure. Because of this, it is not unusual to find that many of the larger, steel pressure tanks have been converted into unique structures or repurposed for other uses. Some of the larger steel pressure tanks have been converted into unusual, multilevel round houses. Some of these houses are elevated, while others are ground level or subterranean. Steel pressure tanks have also been adopted…

In the “ If the earth has layers than the top layer is the least dense.” the hypothesis was accepted. Data that supports this is that canister number one had the least amount of sand and a density of 0.40g/mL3.This canister was the least dense of the three canisters. This is why it floated on the surface of the water. Opposed to canisters numbers two with more sand than canister number two and canister number three had the most sand .Water’s density is 1 g/mL3 . The reason canister one floated…
