Arabidopsis thaliana is found in the mustard family and is a weed used as a model organism to aid in research. Over the years, research has taken off due to this and other model organisms for many reasons. A short generation time is ideal so that experiments can be conducted in a timely manner. Arabidopsis […]

Both clinical and research applications often need to determine the quantity of microbes. This determination is crucial for assessing antibiotic effectiveness, therapy in clinical settings, as well as the efficiency of antimicrobial chemicals and radiation in research settings. The viable count method is commonly employed to quantify bacteria, specifically counting only living and reproducing microbes. […]

A. Define the following: Enriched Media: An enrichment medium contains some important growth factor (vitamin, amino acid, blood component, or carbon source) necessary for the growth of fastidious organisms. Selective Media: Selective media allow for the selection of particular microorganisms that may be present in a mixed culture. Selective media usually contain a component that […]

The word pyrometer originated from the Greek word, fire, ” (pyro), and meter, meaning to measure. Pyrometry is the science of measuring temperature greater than 1500 degree Celsius and therefore Pyrometer is the instrument that is used to generally measure high temperatures.  They usually measure the temperature of the surface of the object. The surface […]

The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver, blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed, ammonium sulfate was added to the supernatant, chilled and then spun […]

Hematite Mineral Processing Equipment The process of hematite mineral processing equipment consists of crushing, grinding, and classification. The specific circumstances determine the type of equipment used in the process. Let’s explore the different types of hematite mineral processing equipment and their applications. Here are the various types: Crushing equipment: jaw crusher, impact crusher, cone crusher. […]

Hair coloring or lightening is the practice of changing the color of hair. During lightening, hair goes through various stages until it reaches the ideal orange/gold color. Lightening time varies, depending on natural hair color. The darker the hair, the longer the lightening time needed. Medium brown hair on average takes somewhere around 40 minutes […]

“Is the Parkerian Hexad superior to the CIA Triad in describing the framework necessary for information systems security? ” Yes, the Parkerian Hexad is superior to the CIA Triad because it is an updated approach that expands on the original three elements of the CIA Triad. In order to answer this question let’s look at […]

Mineral occurrence in igneous rock is most simply explained by Bowen’s reaction series. Norman Levi Bowen discovered the series of reactions while studying the process of crystallizing minerals in Washington, D. C. in 1928. In order to best express his findings to his scientific brethren, Bowen created a visual display based on when and under […]

I am pleased to announce that cobalt is a unique element with its own gum. While not relevant to my report, I enjoy its juicy, minty, and long-lasting flavor because it stimulates the senses. Moving forward, I will provide more information about cobalt, including its definition and origins. In 1739, Swedish chemist Georg Brandt aimed […]

The Expirement that the chemist will be conducting includes the following materials: hot water, room tepmerature water, cold water, and regular Alka Seltzer tablets. Research on Alka Seltzer in previous expirements shows that it dissolves faster in hotter temperatures of water. It also shows in previous expirements that Alka Seltzer dissolves slower in colder temperatures […]

Phiten bracelets and necklaces have become very popular in the world of sports. The main sports they are used in is baseball and golf. At Phiten, they claim that their necklaces will “add energy” and “help people enhance their quality of life” (Hirata). The makers of Phiten say claim to use a special way of […]

The purpose of these experiments is to examine the driving force behind the movement of substances across a selective or semiperpeable plasma membrane. Experiment simulations examine substances that move passively through a semipermeable membrane, and those that require active transport. Those that move passively through the membrane will do so in these simulations by facilitated […]

The noblest efforts of a hero, ironically involves him in guilt and leads him to misery. Thomas Hardy’s novel, The Mayor of Casterbridge concentrates mainly on the life and events of a certain Michael Henchard..

Szymborska’s work has been considered grim poetry because she tackles on the subject of war and its aftermath, […]

‘Clean coal technology’ is a term that denotes the evolution of techniques aimed at reducing the environmental impact associated with producing energy from coal. This terminology implies that coal could potentially be a fuel source emitting negligible or no carbon dioxide and other harmful substances. There are several techniques that can be utilized to reach […]

Joseph Louis Proust was born on September 26, 1754 in Angers, France. Though there is not much information about his family, his father and Joachim, his brother, were pharmicists. Other than being a chemist, Joseph was a teacher at the Chemistry School in Segovia and at the University of Salamanca which were both in Spain. […]

An offer is a critical component of a contract, a legal agreement established between two or more entities. Other crucial factors include Acceptance, Consideration, Position, and Capability. If any of these components are missing, the contract will be deemed invalid. A proposal, otherwise known as an offer, is a precise promise or proposition that commits […]

he use of transition metal oxides, such as Co3O4, as positive electrode materials in lithium ion batteries (LIBs) has attracted great interest due to their high discharge-charge capacity. However, the poor capacity retention of the materials caused by large volume changes during the cycling process limits their cycle life time. Therefore I propose gold nanoparticles […]

Staffing issues are an essential element in the success of foreign, multi-national, corporations. In many instances, companies will promote from within in order to utilize the reserves of high potential employees without the need to rely on the external labor market, which could impact the company’s overall performance. As an HR manager for Bosch, overseeing […]

This report discusses an experiment that was done to demonstrate the effects of lysozyme on populations of Gram positive and Gram negative bacteria. Bacteria have a cell wall composed of peptidoglycan that gives the wall its strength. Gram negative bacteria have and extra component of lipopolysaccharide (LPS), that is stabilized with magnesium ions, to their […]
