of addition of PVA in Boehmite sol during peptization on the viscosity, coating time, pore size and BET surface area is presented in Table I,II,III, and IV. PVA was prepared by dissolving 2, 4, 6 and 8g of PVA powder into 100mL de-ionized distilled water. PVA with different concentration in the sol give a of characteristics viscosity range. It was noted that the viscosity of the sol increased as the PVA addition was increased. On the contrary, the coating time and BET surface area decrease as…

15 min, the solution was heated to 65oC, 0.1 mol ofp-methoxyacetophenone was introduced into a dropwise to the solution for about 6 h. Then the mixture was transferred into 30 mL boiling water containing 2N KOH. The solid product was filtered and acidified with dilute sulphuric acid, then washed with distilled water and dried at 65oC for 12 h. Recrystallization from benzene-aetonewater system gavecrystals. Yield: 82-92 %. Synthesis of 1-(p-Methoxyphenyl)-1,…

Process / Revelation Outline I head out the door for work knowing that I am running late, I am surprised and stop cold because my car is overlaid with snow and I cannot drive until the snow is cleared off the car. This essay will cover the topic of snow on your vehicle and planning ahead for safety. Coming from the North, I am contemplating there probably are many Southerners that have no concept of how to remove snow off their car. The purpose of this essay is to explain how to get the snow…

release of fat. The tubes are centrifuged and the fat rising into the calibrated part of the tube is measured as a percentage of the fat content of the milk sample. Apparatus: - Butyro meter, 10.75ml pipette,amyl alcohol, stoppers, gerber centrifuge, water bath. Reagents:-Sulphuric acid, amyl alcohol. Procedure:-  Transfer 10 ml of sulphuric acid in to butyro meter .  Warm the sample approximately to 270C and mix thoroughly but do not shake it so vigorously as to cause churning of the fat.…

What a blighted day. I was hoping to go out to the sea drowning myself in the cool sea water fighting against the heat wave. But it wasn’t that easy. Flying through the air with a hunk of metal would be crazy talk but in the days where internet doesn’t exist. The flight was pleasant, the air stewardess were gorgeous with their curves all at the right place. The flight meal for once taste amazing. Absolutely amazing. Who would have thought I would enjoy an airplane meal. Yet there will always…

To clean the wells, we used diluted 7X detergent, we rinsed them with high purity water and methanol, blotted them dry with lens paper. The wells were then assembled by sticking and removing a piece of scotch tape from each face of the well and then sticking the well to glass coverslips. While the wells were being cleaned and assembled…

The Blackfish documentary was made by Gabriela Cowperthwaite in 2013. In order to show that Blackfish is propaganda against SeaWorld, their claims about Tilikum and the accidents surrounding him as well as how he was introduced to SeaWorld, its claims about how SeaWorld functioned based on information from ex-employees some of whom haven’t worked there for over twenty years, incidents such as deaths and injuries occurring on and off of SeaWorld property, the claims and sequences where science…

The drop slide By: Maggie Emma and I were walking up the stairs to get to the water slide we wanted to ride on at Zehnders. Zehnders was very big. It had an inside part of it with a bunch of baby slides, and an outside part that was very tall and was covered in kind of clear glass, and had all of the fun rides, and the drop slide was at the very top of it. The slide went super fast, it dropped you straight down about 20 feet. The ride was…

The effect of caffeine on the heart rate of Daphnia pulex Introduction In this experiment the effect of caffeine on the heart rate of Daphnia will be tested by use of a microscope and caffeine solution. Daphnia pulex is a crustaceous animal found in the ocean. There internal organs can be visible to observe because their body is translucent. This would be interesting because we could see how the effect of caffeine effects the heart rate of humans as well. Carrie miller from university of…

Mass wasting, also known as slope movement or mass movement, is the geomorphic process by which soil, sand, regolith, and rock move downslope typically as a mass, largely under the force of gravity, but frequently affected by water and water content as in submarine environments and mudslides When the gravitational force acting on a slope exceeds its resisting force, slope failure (mass wasting) occurs. The slope material's strength and cohesion and the amount of internal friction between…
