Literature Review: 2.1 Introduction Modern peat soil research focus on peat soil improvement using chemical stabilization since 19th century. The stabilizer that can be used for the peat soil chemical stabilization have increased in varieties. Ordinary Portland cement and lime are two of the most common peat soil stabilizer found. However, due to the scarcity of the natural resources, substitution for the peat soil stabilization study was done in recent. In this context, few of the researches…

The purpose of this spectroscopy, atomic spectra, and light lab was to further your understanding of how different gases are given specific wavelengths based on the variety of color that their light gives off. (Grossie, 285). Every ion gives off a different light configuration based on the amount of energy they hold. (Grossie, 285). A spectroscope is used to break down the light given off by the gas into different colored lines in different areas on the scope. The measure of these lines is what…

Purpose: To study sliding friction and to determine the coefficients of static and kinetic friction. Theory: Friction is a force that opposes motion. Static friction prevents an objects being set into motion by an external force. Kinetic friction opposes the progress of a sliding object. Static friction is given by Fs< usn where N is the normal force between the object and its support surface and us is the coefficient of static friction. There-fore, the coefficient of static friction is…

Research: According to Newton 's Second law when force is increased acceleration increases assuming that mass stays constant. a=F/m Purpose: The purpose of this lab is to prove when force increases acceleration also increases. The independent variable is amount of force applied to the Lenny Board and the dependant variable is the acceleration of the Lenny Board. 3 controlled variables are mass, surface of testing, and the Lenny Board (the weight, the amount of grease on the bearings, ECT) itself…

Diagram 1.6: Diagram showing tension force in the string (from 0 cm increasing in 1 cm until a displacement of 15 cm has been attained) This diagram shows the manner in which the tension force applied to the string was calculated. Starting at 0 centimeters, forces were provided in the string such that the string would extend one additional centimeter from the previous measurement. Using the Capstone® software, the force applied to the string was calculated at the given horizontal…

Milaya Ruffin Mr. Simmons Biology October 14, 2016 Research Many people have gone on roller coasters, but have they really thought about how they work? All of the tosses and turns. How does it stay on the track? How does it slow down? How does it speed up? Slow and clanking, the string of cars is pulled up to the highest point of a roller coaster. One by one, the cars start going downhill on the other side, until gravity kicks into action and the full weight of the train is going down into…

Supplemental information for “Colloidal Type-II CdS/ZnSe NCs : Synthesis, Electronic Structures, and Spectroscopic Properties” S.A. Ivanov, A. Piryatinski, J. Nanda, S. Tretiak, D. Werder, V. I. Klimov Theoretical model. To describe quantum states in a spherically symmetric Type-II core/shell nanocrystals (NC) characterized by the core radius R and the shell width H, we use effective mass approximation. We assume the existence of single energy bands for both electrons and holes. This assumption…

Multi-stage fracturing is an advanced drilling technology that enhances the production capabilities through maximizing the contact area of unconventional wells with the reservoir production zones. During the fracturing process, a special fluid (primarily a mixture of sand and water) is blown out at a high pressure into the shale rock formation creating channels through which hydrocarbons can easily migrate to the well. Multi-stage fracturing is a combination of fracturing and plugging processes.…

Newton's three laws of motion consist of information about gravity, force and acceleration. The law’s where written by Newton in 1666. Each law explains a different theory about how gravity works. The first law talks about why objects stay in motion or rest unless an unbalanced force is acted upon that object. The next law explains how force equals acceleration. The third law talks about how if any action is created there is a equal and opposite reaction that appears. Each one of these laws…

It begins with a couple of pedal strokes. Round and Round the wheels turn and your off like a shot. Sounds straightforward? Traveling across rural scenery. I love it. Edinburgh should be called the Happy Trails city once you get away out of the city there are a million of places to run, walk, hike or bike. I go mountain biking every Monday night with the club. For the first 5 minutes my muscles burn, it feels like I am dragging myself through mud and being stewed alive all at the same time. Then…
