Analysis of two and four-lead resistance measurements Johnny Greavu University of Minnesota-Twin Cities September 29‚ 2014 Introduction We measured the resistance per foot of a wire using setups of both two and four test leads in tandem with a digital voltmeter (DVM) and compared their accuracy. While resistance can be determined by measuring voltage and current separately‚ it can also be measured more simply and directly using the resistance measuring feature available to some digital voltmeters

The Problems with Antibiotic-Resistant Bacteria Rhoshandia Agboje University of Phoenix Online Abstract The aim is to summarize‚ evaluate and argue the validity of information that demonstrates the issues with antibiotic-resistant bacteria. A plan to minimize/reduce these issues in the future shall be presented with explanations regarding effectiveness. The Problems with Antibiotic-Resistant Bacteria Antibiotic-Resistance is the ability of bacteria and other microorganisms to resist the effects of

The Negative Effects of Peaceful Resistance Civil disobedience is the way in which peaceful resistance comes to play. Gandhi in Gandhi and Civil Disobedience states that “In my humble opinion‚ noncooperation with evil is as much a duty as is cooperation with good”‚ this is significant because when people riot‚ burn buildings or make threats‚ that is not anymore effective as when people hold up signs and chant. Peaceful resistance to laws negatively impact a free society by resorting to violence‚

In the 1940s antibiotics were widely introduced as a cure for common types of diseases. However‚ some of the diseases started to build up a resistance to the antibiotics and in result‚ the antibiotics became ineffective. In order to help resolve the crisis‚ antibiotics were found through screenings of soil microorganisms. However‚ soil microorganism’s antibiotics were depleted by the 1960s and their antibiotic effects were unable to be replicated through synthesis. In this experiment‚ the researchers

Antibiotics are used for treating human infections that are caused by specific bacteria‚ fungi‚ protozoans‚ and other large viruses. They are generally grouped with the class of microorganisms that they inhibit. Antibiotics are used to fight off infections within the human body system by inhibiting the growth of its infectious microbes. Antibiotics have been considered one of the greatest newest innovations in medicine but there is still yet to be a perfect ideal antibiotic. In this experiment six

Physics GCSE coursework: Resistance of wire Aim: To investigate if the length of wire affects its resistance. Prediction (Hypothesis): I predict that the longer the wire the higher the resistance‚ and the shorter the wire the lower the resistance. Knowledge: Resistance is that property of electric components that turn electric energy into heat in opposing the passing of an electric current.It can be beneficial‚ as in electric heaters‚ or a pest‚ as in light bulbs‚ where the heat

to ‚ what type‚ location‚ severity of symptoms‚ and which antibiotics the strain of MRSA is not resistant towards. The “best” treatment for MRSA would be prevention of MRSA contraction and/or spread of MRSA from patient to patients(MSRA 2017). Proper hand washing‚ hygienics‚ keeping personal items of your own and each patient’s separate‚ and following protocols for treating a patient with confirmed MRSA. What could happen if the resistance continues to

The debate of whether bacteriophages could replace antibiotics is one of the many health issues to be explored in this essay. Bacteriophages are viruses that specifically target bacteria in your body to destroy it. Many scientists believe that bacteriophages will replace antibiotics in the fight against bacterial/diseases‚ although ideal‚ scientist do not know the long term effects of using this mechanism of defense. More research is needed and thus the push for bacteriophage usage may be reluctant

Microbiology Abstract: The purpose of this lab was to use the Kirby-Bauer method to test the sensitivity of Staphylococcus epidermis of specific areas on a petri dish. The antibiotics were gentamicin‚ novobiacin‚ and penicillin. This resembled a culture and sensitivity test that is preformed at the hospital’s laboratory to find out the resistance of a microorganism. This experiment was meant to use the naked eye and a magnifying glass when necessary. Procedures: This experiment called for prepared agar in

Richard Dogmagk experimented with a red dye called prontosil and found that it had strange healing effects‚ when he injected the dye into mice with severe streptococcus infections‚ they all survived. Dogmagk had discovered the one of the fist antibiotics‚ specifically the first Sulfa drug. When scientists isolated the active part of the prontosil molecule they discovered how it and all sulfa drugs work. Sulfa drugs contain a sulfur atom that has six total bonds (shared electrons) and six electrons
