Results and discussion 4.1 Material removal rate The material removed from each coupon was determined by measuring its mass before and after electro-polishing. Theoretical values were then obtained using Faraday’s laws of electrolysis as shown in Equation 9. (9) Where m is the mass of material removed in grams, I is the current and t is the electro-polishing time. EW is the equivalent weight which depends on the chemical composition of…

CHAPTER II. REVIEW OF THE RELATED LITERATURE A. Temporary Magnet Temporary magnets are those that essentially demonstration like permanent magnets when they are inside a strong magnetic field (Jezek, 2015). They are not like permanent magnets when it's not around in a magnetic field because it loses its own magnetism. Temporary magnets cannot remain magnetized on their own (Boyer 2017). Paperclips, press nails, and other comparative things are cases of temporary magnets. Temporary magnets are…

5.2.2.2 Interpretation of Regression Model The above equation can be written as D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) ) By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below: As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

The writing process is both complex and interesting at the same time. There are many ways to write and the process is different for everyone. In this essay, I will explain my found writing process and analyze my process alongside Peter Elbow’s Teaching Thinking by Teaching Writing, Alvarez’s Writing Matters, and Stafford’s A Way of Writing. My first step in writing begins with choosing the right location. Usually I choose my office or bedroom, but sometimes when I stick to a routine, I become…

CH 204 – Introduction to Chemical Practice Experiment 10 – Kinetics Joshua Fu* Tien Tran TA: Jamie Trindell April 25, 2016 INTRODUCTION This experiment focused on the concept of chemical kinetics, which describes the speed at which a chemical reaction occurs and the amount of reactant or product remaining after a specific period of time. Kinetics is important in analyzing the rates of certain species and reactions, and is a crucial technique to predict different reactions. Kinetics is…

investors will not pay for risk premiums, and defined by following stochastic differential equations: (1) (2) Where: S(t) represents the price process of an underlying assets. V(t) is the variance of the corresponding instantaneous returns. And the initial condition S(0), V(0) should be strictly positive. r is the risk-free return rate (non-negative…

Influenced through encounters with China and the West, the Japanese explored mathematical topics that were relevant to their time, which led to Japan’s shift from wasan (和算, Japanese Mathematics) to yôsan (洋算, Western Mathematics) in the Meiji era, and ultimately various technological advancements. As seen in Japan’s first encounters with the west, Sakoku (鎖国, the national seclusion policy) was the direct result of distrust of the Christian missionaries, which led to limited trade of ideas. In…

diluted with DI water and reacted to produce an unknown amount of FeSCN2+ ions in an equilibrium reaction. The absorbance of each solution was found using a spectrophotometer, the first five of which was used to create a calibration curve, whose equation relates the concentration and absorbance of FeSCN2+ ions. Theories…

Genealogists photograph tombstones to document the birth, death and burial information of their ancestors. This post will give you some tips on how to get the best possible results when taking those important pictures. Locating Cemeteries Your first challenge might well be just getting to the cemetery. Hopefully you have an obituary or burial record for your ancestor that gives the name of the cemetery. Depending on how old the record is, finding the cemetery can be very easy or impossible.…

A. i) The rate of a reaction is the change of a substance’s concentration per units of time. The reaction rate of an experiment is dependent on many things including concentration, presence of a catalyst, and, most importantly, temperature. Temperature and reaction rate are directly correlated, which means that as one increases, so does the other. It is a general approximation that the rate of a reaction will increase by a factor of two for every 10°C jump in temperature. Increased temperature…
