….. Of Life, Taker of Souls People say that the eyes are the windows to the soul, if only they that really meant. If someone is lying, looking a person in they eye will allow to to see right through them. If a person is hurt, sad, or even heart broken, all you have to do is make eye contact to know what they are feeling. The same is for people who are are in love, happy, and glad. The eyes show and see all. But this is only a small part of what I can see when I look someone in the eyes.…

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…

properties of states of matter, properties of water, and experiments of water and ice, there is some evidence that makes this a bit of a complex case. In Chemistry, we generally refer to three states of matter when trying to describe a substance; solid, liquid, and gas. Each of these three states of matter has their own properties and behaviors.…

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…

the temperature at which a solid becomes a liquid (Bruice 2014). On the molecular level, when a compound melts the forces between the molecules become weaker. This is because when a substances heats up the kinetic energy between the molecules increase causing the molecules to vibrate. When the vibrations become strong enough for the molecules to move around and pass other molecules, the compound that is being heated up starts to melt and become a liquid. In this lab, five different ratios of…

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…

The meniscus, also stated before, gave the students a measuring problem in the beginning, when filling up the graduated cylinder to 100 mL. In Lab Debrief Part One, we discussed this situation and later found out that the meniscus was a curve of the liquid and could be either convex or concave. An observation in the experiment was when the pennies were displacing both water and milk, which created convex meniscus; this was the effect of surface tension. Surface tension was a large aspect of our…

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 &…
