Impact of the Rabies Virus: Risks and Preventative Measures for Health and Safety Megan Goebel MMI 133 Dr. Judy Gnarpe It is uncommon today to not have a pet as a family member or have zero contact with animals. Due to this increasing trend, it is important to be aware of the risks from zoonotic diseases that can be transmitted to humans. As a new owner, I was given the opportunity to learn from a veterinarian about the health of my pet and common diseases that are preventable with great…

Should Parents Vaccinate Their Children? Vaccinating for common childhood diseases is controversial in today’s society. Many parents are unsure of whether to vaccinate their children and if the vaccinations their children receive are safe and will protect them. Parents should vaccinate their children because, often, vaccines do more good than harm and they do help protect children from dangerous diseases. Children have weaker immune systems than adults and vaccines help keep them safe from many…

this subject. Nonetheless, chemistry is all around us, as demonstrated by the following diagram, which clearly demonstrate the chemicals present in a cup of coffee. For example, the chemicals presented in this figure are: caffeine, chrorogenic acid, phenols, and citric acid. These are generally the chemicals that give coffee its unique taste. Why Is Chemistry Important in Life Most teachers find it hard to answer this question comprehensively in a classroom setting since chemistry is all…

Total K in soil was determined using Flame photometry method (Bao, 2000). Available K in soil was determined using 1 N ammonium acetate extraction-flame photometry method (Bao, 2000). Urease activity was determined using phenol-sodium hypochlorite colorimetry and expressed as mg NH3-N Kg-1 d-1 (Guan et al. 1986). Nitrite reductase activity was determined using the Gerry reagent method and expressed as mg NO2-N g-1 d-1 (Li et al. 2008). Protease activity was determined and…

quantity taken for amino acid analysis. Diluted hydrochloric acid was used for Free amino extraction. Nitrogenous macromolecules that were co-extracted were precipitated using sulfosalicylic acid and removed by filtration. A mixture of performic acid and phenol was used for Oxidation at 0°C. Hydrolysates of the sample were then adjusted to pH 2.2 using 7.5M sodium hydroxide sol. Amino acid analyzer based on ion exchange chromatography was used to separate amino acids. Amino acids were…

The experiment made use of two reactions in synthesizing 1-phenylazo-2-naphtol, also known as Sudan-1. The first is the diazotization reaction in which a diazonium salt is formed from the conversion of primary aromatic amines, such as aniline, to compounds with the nitroso functional group using a nitrous acid, such as HNO2. The diazonium salt was then used as an electrophile in a coupling reaction with an aromatic compound, β-naphthol. Recrystallization was conducted and yielded 0.18 g of a…

Auschwitz was a gruesome concentration camp in Oswiecim, Poland during World War II (“Auschwitz- Birkenau”). Auschwitz was established on May 26, 1940 by German Nazis (“Auschwitz-Birkenau”). Auschwitz is known to be the largest and most notorious out of all the death camps (History.com Staff). More people died at Auschwitz than at any other concentration camp (Arnett, George). There were three main Auschwitz camps and many sub-camps. The three main camps include, Auschwitz I (the main camp),…

Human experimentation Since the beginning of mankind we have managed to be the dominate species of the Earth; however, we are far from peaceful with warfare, slavery, starvation, and experimenting on our own kind. Humans have done some pretty twisted and inhuman things such as the Nazi Holocaust Experiment and Project MK-Ultra. Before, during, and after WWII, Nazi’s conducted many medical experiments on the Gypsies, Slavs (Large group of Ethnolinguistic in Europe), and Jews they held in…

After, then other biochemical tests were performed that were specific to the gram- negative bacteria to start the identification process of the unknown. The results of the gram negative tests lead to the identification of the bacteria Alcaligenes faecalis. The gram stain procedure was the first test performed by isolating a colony from the pure culture streak plate. The gram stain was followed orderly right from the referenced laboratory manual. The test resulted to be Gram- Negative bacteria…

1. Differential diagnosis (names of possible bacteria) You should include at least 6 most relevant bacteria that can cause signs and symptoms given in the case study and rationale for including each of them (1 sentence maximum for each). An elderly man at the hospital emergency has symptoms of high temperature (at 103oF) and an above respiratory rate. Possible bacterial pathogens that could have caused his illness are: Haemophilus influenza – this bacterium, which is more susceptible to the…
