You should always make sure the engine is off and you are removing the battery and its cables correctly so that you don't cause harm to yourself or the battery.…

This week's reflection assignment consists of one video. It features Mr. Larry Potterfield (founder, and CEO of Midway USA) as the presenter. The video is titled "Gunsmithing: How to properly polish the metal parts on a Remington 700". Mr. Potterfield begins his first video by stating the objective, polishing metal parts. In his hands, he holds the barrel of a Remington 700 series rifle. It appears as if the rifle has definitely seen some cleaner days, in my opinion. This is a skill every…

Hair is made up of different layers and structures. It is the tough protein keratin that forms the strength of your hair, nails and the outer layer of skin. Keratin is a large molecule made up of smaller units called amino acids, which join to form a chain. The hair shaft is formed of three layers the medulla, cortex, and cuticle. The medulla is the deepest layer of the hair shaft, only seen in large and thick hairs. The cortex is the middle layer of the hair shaft which provides the strength,…

To begin, a little history lesson on the development of this magical drug may be helpful. As early as 1895, the bacteria Clostridium Botulinum, was identified. In the 1920’s Botulinum Toxin Type A was isolated in a purified form. In 1946, the purified Botulinum Toxin Type A was transformed into a crystalline form so that further research of the molecule could be studied. In the 1950’s it was discovered that when the Botulinum Toxin Type A was injected into a hyperactive muscle it blocked the…

Radium Springs is an Unincorporated community that is located in the coastal plain area which is right below the piedmont region. The exact location of the Radium Spring is Southwest on the outskirts of Albany Georgia in Dougherty county. The Radium spring is one of Georgia’s seven wonders and the largest natural artesian spring in the state of Georgia. The formation of this spring is due to the karst topography where the surface of the water infiltrated the earth crust surface that became the…

Introduction: The “wonder” drug is what it was called. They believed it was like magic. It glowed in the night, it was presumed to cure cancer, it even was thought to give you eternal life, but for many innocent young girls in the 1920's, it was anything but wonderful and exquisite(Prisco). It was fatal. The chemical Radium and the Radium Girls is an event that not only affected the lives of many of these young girls but thousands of others globally who believed that radium was once one of the…

Before beginning the experiment, wash hands with soap and warm water, then put on apron, safety goggles, face mask and gloves. 3. Disinfect the work area with bleach and paper towels. Then pour some bleach in a bucket for anything that…

2. The gas phase catalytic oxidation of benzene reactor model and evaluation of the parametric sensitivity To illustrate the parametric sensitivity analysis, the case of gaseous phase catalytic oxidation of benzene to maleic anhydride was considered (Lupușor et al., 1981). The multi-tubular reactor (heat exchanger type) with the fixed bed catalyst inside a small diameter tubes (under 3 -4 cm) is continously cooled by molten salt mixture (nitrates and nitrites mixture; Maria , 2007). The raw…

In experiment 2, we observed that the reaction of halogenoalkanes with aqueous alkali and water which contains dissolved silver nitrate. Halogenoalkanes are alkanes which have one or more hydrogen atoms replaced by halogen atoms such as fluorine (F), chlorine (Cl), bromine (Br) and iodine (I) which are the elements in group 7 in periodic table. Halogenoalkanes have the general formula, RX, whereby R is an alkyl or substituted alkyl group and X is any of the halogen atom. Besides, halogenoalkanes…

the Iron was attracted to the Magnet. When it comes to the separation of Sand and Sodium chloride, they were separated because of the unique property of Sodium Chloride which is solubility. When the mixture of Sand and Sodium chloride was mixed in the water, the sodium chloride had the capacity of being dissolved in the water leaving the sand undissolved. When the mixture was filtered using a filer paper, the Sodium chloride went through the filter paper because it was soluble in water but the…
