I live in a suburban area in San Diego, where violence is heavily decreasing. Although the impacts of gangs and drugs in my neighborhood have subsided, does not necessarily mean that I remained unscathed; I come from a family of nine; four brothers, four sisters (including myself), and one widowed mother. You can imagine how crowded I’ve been all my life. The fact was that this was my reality, living in a crowded home with lingering drugs and marital issues. Despite the flaws in my home, and…

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…

Fly fishing has been around for many years. Not only because it is easy to learn, but also for the fact that it is fun and offers so many benefits. With the best fly tying kit and a bit of confidence, you can have a great day fly fishing regardless of your angling experience. However, choosing the best kit for your needs can be a bit of a minefield especially if you’re a novice in fly fishing. Basically, an excellent kit should contain everything you may need including scissors, dubbing twister,…

RESEARCH TASK AND WRITTEN REPORT Many theoretical and experimental problems were not solved in the early twentieth century. There were attempts to explain the behaviour of matter on the atomic level with the laws of classical physics however they were not accurate nor successful. It was not until the period between 1900 and 1930 where a revolution occurred and a generalised formulation called quantum mechanic was developed. And since the understanding of the structure of the nucleus of the atoms…

individual cannot recognize faces. He was able to overcome his face blindness by drawing or painting their face. Speaking of his art, he has done so many different styles that I can’t possible fit them into this essay but here are some. He has used ink, graphite, pastel, watercolor and so many more, but I will explain how he used the grid method for his photo realism art. The grid method is when an artist draws a grid over a reference photo and then drawing a grid of equal ratio on their work…

art as an emotional and creative outlet. Turns out, I was right to overlook her opinion because today, my innovative art from my six-year old creativity garnered gasps and compliments. I took pride in my finished works of acrylic paint, ink, and graphite, but I could not help but notice a sense of unproductiveness. Since the intent of my art was personal, the static works never left in my drab bedroom walls until junior year started.…

(Hornbostel, 1991). According to Harper (2001), Beryllium oxide, with a melting point of 2585 °C and specific gravity of 3.025, is a cubic close-packed and has a zinc blende structure. It is stable in dry atmospheres. At high temperature, it reacts with graphite. And for 1100 °C and above, it hydrolyzes. It is electrically resistant and is a good thermal…

Alumina Dandruff is a state of hair scalp form that causes peeling white or yellow scales. It is also clinically phrased as seborrhea dermatitis of the mysterious cause. Greasy skin is frequently connected with this trouble. A lot of people have this setback which is distinct by burning and excessive peeling of the scalp. It is not infectious, infrequently serious and it can frequently be restricted. A homeopathic treatment for dandruff may be fruitful to combat this problem • Causes of…

Toyota Corolla vs. Nissan Sentra Although the Toyota Corolla has been around since 1966, and the Nissan Sentra only since 1982, both have stood their test of time. For any incoming college student or newly married couple both Corolla and Sentra have proven to be the most popular among all of the compact cars. The reasons for this phenomenon are their reasonable starting prices, how many miles to the gallon they get also known as fuel economy and the wide range of colors offered. Now let us see…

Hall’s earliest achievement was when he used a process to obtain his first sample of aluminum in his parents shed. "The process was the electrolysis of aluminum oxide dissolved in a mixture of molten cryolite and aluminum fluoride in a graphite crucible" (Craig). Hall applied for a patent and in 1886 and received it in 1889. Later that year, Hall received money from a man named Alfred E. Hunt and some other business men. Together Hall and these men founded the Pittsburg Reduction Company…
