The food products we consume are made up of at least one ingredient and, in the case of processed foods, individual ingredients are often quite numerous. In the interest of understanding the origins of just one ingredient, I looked to my favorite processed fitness supplement. I am personally very fond of physical activity and, subsequently, I have always valued protein in my diet. Protein is vital for maintaining the body’s metabolic functions and it also aids in muscle repair and growth.…

Summary The goal of the experiment was to determine weight % of sulfate inside an unknown sample compose of Na2SO4. The sample was dried, weighed and dissolved in water and hydrochloric acid. Barium chloride was then added in excess to drive the precipitation process to completion. Heat was use to digest the precipitate before it was filtered through an ashless filter paper and ignited to constant weight. From mass of the sample and mass of the precipitate, the percentage of sulfate in the…

A Battery (Electricity) is a device that makes electric current through motion of cells which are the components of the battery. They are devices that convert their inner chemical energy into electrical energy. A battery has of two or more cells which are connected together in order to give out electricity. Batteries are commonly used in single cells such as the ones used to power radios, watches and small electrical appliances that are used in everyday life. They are also used to supply energy…

METHODOLOGY: The evaluation of ceramic waste and hypo sludge for replacement of cement material begins with the concrete testing. Concrete contains cement, water, fine aggregate, coarse aggregate and grit With the control concrete, i.e 0%, 5%, 10%, 15% ,20% of the cement is replaced with ceramic waste & hypo sludge the data compared with data from a standard concrete without ceramic waste and HYPOSLUDGE individually. Three cube samples were cast on the mould of size 150 X 150 X 150 mm and…

Chalcopyrite is a copper iron sulfide mineral. Its coloring is metallic brassy to a brown-orange, and on the Mohs scale, it has a hardness of 3.5 to 4. The chemical formula of chalcopyrite is CuFeS2. It is the most commonly occurring copper containing mineral in New Zealand, but it is only created near volcanic areas. On the metaphysical level, chalcopyrite is used for meditation, specifically for opening the third eye chakra (crown chakra), and physical healing. The stone clears any energy…

The action and adventure subgenre in movies has “long established features of Hollywood productions as well that of other national cinemas” (Tasker). This subgenre has elements of an adventure which includes journey, quest, or discovery that takes place in a “fantasy and exoticized setting” (Action and Adventure Films) along with incredible scenes of violent, combative, explosive, and pursuit action sequences. Action sequences can also be “comic… apocalyptic, military, conspiratorial and even…

Since ancient Greece, humanity has become fascinated with science. The development of new technologies that will further the existence of mankind, has been the goal for many great scientists. Through centuries of experimenting, the mid-evil era of alchemy, and many years after, Chemistry became a topic of much importance. During the 1800’s, science had become one of the most rapidly growing fields as explanations for how things work, or the technological progression allowing us to discover more.…

48-5.89 millimols per liter. The results of the case study were gathered by using heparinized tubes and a centrifuge immediately. Plasma potassium levels were analyzed using flame photometry (uses flame and flame color to measure concentration of alkali metals in a substance.), blood glucose was analyzed using a Beckman analyzer, and blood insulin levels were measured using radioimmunoassay (uses radioactive antigens to measure concentration of hormones in blood). All results were weighted on an…

Tuberculosis (TB) is one of the most lethal infectious disease among worldwide. This disease is known as white plague and as infected individuals for centuries. It was not until the mid 1800s that people discovered that the mode of transmission was spread from person to person, and not hereditary.1 During this time scientists found that TB was contagious and was caused by a specific bacterium. Although, treatment for TB would be introduced over 50 years later, and people who suffered with TB…
