You Must use Turnitin to submit the exam. Water and Sewage Microbiology: 1. List the steps of in a water purification plant. a. Screening to separate the large contaminants from the water b. Coagulation to attract small contaminants c. Sedimentation where water sits and finishes coagulation d. Filtration to remove any small remaining contaminants and particles e. Disinfection by disinfecting chemicals such as chlorine to kill microorganism or remaining bacteria 2.
This is because, unlike other types of mercury compounds like methylmercury, ethylmercury can clear through the bloodstream extremely quickly, meaning that pollution of the environment with Thimerosal will not lead to negative effects on the tertiary consumers of ecosystems (such as large fish). The lack of bioaccumulation and incredibly small concentrations of pollutant is why the chemical Thimerosal has negligible negative effects on the environment and thus, environmental worries are not ground for placing the chemical on the ban
No serious side effects have been reported with Unienzyme, however, nausea, skin rashes and allergic/hypersensitivity or idiosyncratic reactions is a theoretical possibility. As the medication contains activated charcoal, black faeces, diarrhoea, vomiting and pulmonary aspiration are other possible side effects. 11. For how long should I take Unienzyme? In general, enzyme therapy is safe for long-term use.
Ishida, Hamasaka, and Hanoi 's findings were also found to be accurate, that the Drosophila Melanogaster is not affected by Red Light. Finally regarding Hori’s conclusion that Drosophila Melanogaster have lethal effects, while we did not fully test the hypothesis, it was observed that they do tend to avoid high frequency
This helped us to verify Newton’s second Law of Motion. I believe our “true” objective in this lab was met sufficiently, that was to understand the implications of Newton’s second law. However, the data we gathered does not reflect the theoretical value of gravity greatly as we were not able to get a single calculation of G that was under 10m/s^2. Fortunately, our main sources of error were human errors and that does not conclude the second law is false. Therefore, I think errors are
The methods for the study are easy to follow and straightforward. The authors for this study state that there is not substantial evidence through literature to compare these two treatments but from their study you can conclude short term affects are more beneficial for the patient to receive deep friction massage with mobilization exercises to increase their range of motion and decreasing pain short term. This study does not include threats of internal and external validity, confidence in data, or risks and
Gram-negative bacteria contain a layer of lipopolysaccharide (LPS) When the bacteria enters the body, the LPS triggers the body’s immune response. The body recognises a cytokine reaction from the bacteria which is toxic to the body and responds by inflaming the tissues and blood vessels. The certain cells used against the bacteria Bordetella Pertussis include innate and specific defenses, but the defensive antigens have not been exclusively identified. Explain how the disease can be treated. Pertussis is generally treated with antibiotics and it is vital to use the antibiotics early on in the infection or it will have little to no effect.
The simple soap and water can remove physically some kinds of microbes but cannot kill them but antibacterial solution kills or inhibit the microorganisms. In a study of Lilly and Lowbarry soap and water did not effectively reduce count of artificially applied bacteria. On the other hand the application of 70% ethanol to contaminated hands resulted in 99.7% reduction in
However, the fact that Dr. Jones knows Smith actually has virus X does not entail knowledge being that Dr. Jones happened to be luckily correct about her educated guess of the probability of Smith having virus X while satisfying justification and defeasibility conditions. Though defeasibility and justification conditions may defeat belief in some cases, there will always be circumstances that can make the conditions void and cause one to fall short of
The technology can also clean water from high concentrated salt effectively (Nield, 2015, p.2). According to El-Shafi, as cited by Danise (2015, p.1), no electricity is needed if we use pervaporation. C. Disadvantages Despite the good advantages pervaporation provides, it contains some disadvantages. According to Nield (2015, p.2), there is a problem with pervporation and that is the production of water waste during the process. The membranes used in pervaporation might not be able to perform very effeciently (Nield, 2015, p.2).
Random assignment process ensured that both groups sample’s characteristics (low income families, living in same areas, similar environmental context, etc.) are preserved and the control group members did not vary at the beginning of the study, which guaranteed that the only difference between both the treatment and control group was that the treatment group had access to New Hope. Consequently, any significant differences in outcomes that arise a course of the experiment (i.e., employment rates or children achievement) between the two groups can be ascribed to New Hope intervention. Finally, probable barriers to working such as drug abuse and/or mental health were not treated by the research, because New Hope was not designed to address such factors despites the potential impact these variables could had on the
The three elements used to discover Protactinium also belong to the Rare Earth Actinides series. Although Soddy and Cranston figured out a way to stabilize it, Protactinium is one of the very few naturally-occurring Rare Earth Actinides and occurs in soil, rock, plants, and surface water. When inhaled in small amounts, Protactinium can cause cancer in the liver and kidneys, but it does not play a huge biological role. Geologically, it does not affect much, and poses no threat to the Department of Energy or to the safety of groundwater. Protactinium, however, is linked to actinium.
For researchers and manufacturers, there are ways around lack of solubility. (Gao, 2014) Solubility can vary based on other things such as surface area exposed to the solvent. Pain killers are readily soluble and there is no allowance for differences in surface area between the different sized
Tecovirimat, Cidofovir and Brincidofovir were all tried in a laboratory setting on animals that had a disease that was comparable to smallpox and was effective toward the virus. All of these antivirals were not tried on people that had smallpox, but was administered to people that were well. Tecovirimat shown to be safe with minimal side effects. Cidofovir and Brincidofovir that was tried on well people were successful however Cidofovir could be harmful to the kidneys. Brincidofovir had less harmful side effects than Cidofovir.
The unknown bacteria was then tested on multiple selective and differential media. Growth was present on the MacConkey Agar and the colonies were the same color as the plate, which told me my bacteria was gram negative and did not ferment lactose. There was no growth on the Mannitol Salt Agar, and this told me the unknown was not salt tolerant and did not
