and Drug Administration officials hypothesized that the culprit took Extra-Strength Tylenol They worked with FDA officials to create new tamper-evident packaging including foil seals and other obvious features that could warn consumers of foul play. The company also promoted caplets (tablet coated with easy to swallow gelatin) which are more difficult to tamper with. They also lowered the price of Tylenol by 25% to recover lost stock from the crisis. Sales people made presentations about the new
Electrical Resistance Electrical resistance is a property of an electrical circuit that opposes the flow of current. Resistance involves collisions of the current-carrying charged particles with fixed particles that make up the structure of the conductor. Resistance is often considered as localized in such devices as lamps, heaters and resistors in which it predominates, although it is a characteristic of every part of a circuit, including connecting wires and electric transmission lines
Factors Affecting the Resistance of a Wire The aim of this experiment is to investigate one factor that affect the resistance of a wire. I will do this by performing an experiment. First I will need to identify the factors that effect resistance. There are a few factors that affect the resistance, it is determined by the properties an object has. This is know as resistivity. The factors I can investigate are : Ÿ Temperature Ÿ Length Ÿ Cross-sectional area/width Ÿ Material
Hypothesis Warming up the squash ball helps it bounce higher. Variables: Type of Surface Height of Drop - Independent variable Temperature of Ball Material of Ball Acceleration Due To Gravity Mass Angle of Surface Air Resistance Diameter of Ball Height of Bounce - Dependant Variable Plan I aim to find out if warming up squash balls before bouncing them affects the height of its bounce. I will need a squash ball, a meter ruler, goggles, a Bunsen burner, a heat
The Resistance of a Wire Introduction: In this piece of coursework, I have been finding out factors that affect the resistance of a wire. Firstly, I will explain how resistance works. Resistance is when electrons in a wire collide with atoms also in the wire. When the electrons and the atoms collide the electrons start to move slower, which then causes resistance. So, resistance is how hard it is to move electrons through a wire. Now, I am going to tell you what are the factors of wire
Electrical Resistance The electrical resistance of a material is its opposition to the flow of electric current (slowing the flow of electrons down). Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. Resistance is a measure of how hard it is to move the electrons through the wire. A current is the rate of the flow of charge (electrons) and the resistance controls the
------- FACTORS ------- VERTICAL HEIGHT OF SLOPE (THE HIGHER, THE FASTER) ------------------------------------------------- GRADIENT OF THE SLOPE (THE STEEPER, THE FASTER) ----------------------------------------------- AIR RESISTANCE (THE MORE THERE IS, THE SLOWER) FRICTION (THE MORE THERE IS, THE SLOWER) VARIABLES I have chosen to investigate the vertical height of the roller coaster slope. As the car (marble) rolls down the slope, it can be timed, and the length
mass down at a constant rate (at 10 Newton's, or to be precise 9.8 Newton's). Also no matter the size of an object the gravity will still pull the bob down at a constant rate. This will have little effect so I will chosen to exclude this. Air resistance. This will oppose the speed of the bob because as the bob is moving through the air, it will encounter some friction which will oppose its movement, eventually slowing it down. But this cannot be measured, so I will not exclude this variable
* There is no friction because if there was there would be some work done against it and would mean I could not use the conservation of energy. Roller coasters run on wheels against smooth metal which would not have much friction. * Air resistance is negligible as most roller coasters are designed quite aerodynamically and have a large mass which would not be affected by a significant amount. * No energy is lost e.g. sound and heat which would be a result of friction. * There are
bacteria have shown the ability to become resistant to every antibiotic that has been developed [13].Taking unnecessary antibiotic can be dangerous to the health and can increase the risk of antibiotic resistance [14]. World Health Organization (WHO) define the Antimicrobial resistance (AMR) as the resistance of a microorganism to an antimicrobial agent to which it was originally sensitive. [3] Antibiotics were prescribed in 68% of acute respiratory tract visits and of those, 80% were unnecessary according
heart, bloodstream, urinary tract, and skin wounds. Due to vancomycin-resistant Enterococci, many antibiotics have been shown ineffective in the treatment. In this paper, I will describe the ecology and pathology of E. faecalis; the antibacterial resistance; treatment; and, what you can do to prevent Enterococcus infection. Enterococci are normally found inhabiting the large bowls of humans but are also a part of the intestinal micro flora in mammals and birds. Enterococci are also found in soil, plants
The Necessity to Prevent Antibiotic Resistance Approximately one year ago in Kentucky, a man went to sleep thinking he might have caught a flu. The next day, he is rushed to the local hospital while coughing up chunks of lung tissue; within a few hours he experiences organ failure and lips into a coma. Over the next two days, two other patients come in with the same symptoms and die almost immediately. This epidemic that swept over this small area in Kentucky was an ultra resistant strain of staph
Today I will be explaining the importance and details of tracheobronchitis also referred to as bronchitis. Tracheobronchitis as the name gives off is an inflammation of the trachea and bronchitis. The trachea and bronchi’s main role is to extend air into the lungs, so that they are able to reach the alveoli which are responsible for gas exchange in the lungs. Tracheobronchitis is often times not contagious depending upon the cause of inflammation, inflammation can result from an allergic reaction
Advances in Medical Technology Over the course of many centuries, medical technology has developed to a great extent. Studies show that recent equipment has evolved more in the last ten to twenty years than in the past thousand years. Before human time, people learned to treat themselves by just using natural substances. Now-a-days, our hi-tech systems in the medical field have been created for the most effective tools for a high level of patient care. While they advance the tools, it will then
similarities it shares with a widely known disease in humans: Metabolic Syndrome or better known as Type II Diabetes. The condition was suggested in 2002 by Johnson of the University of Missouri Veterinary Medicine College. He proposed insulin resistance, obesity of the neck, tail head and sheath/mammary gland area, and an increased predisposition to laminitis were symptoms of a clinical syndrome in horses and ponies.... ... middle of paper ... ... horses with EMS found that feeding grass hay
. Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order
Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. Because of this resistance, I believe that the use of antibiotics have been proven to be more harmful to human health than helpful. Before I address this topic, it is essential that you know the following: an antibiotic is a medicine that inhibits the growth of, or destroys, microorganisms, antibiotic literally means “against life”; in this case, against microbes, and antibiotic resistance is the ability
the level of glucose in the blood is higher than usual. Type 1 diabetes occurs when the pancreas does not create enough insulin and type 2 diabetes occurs when insulin is produced, but is not adequate in lowering blood glucose levels or there is resistance to the insulin (Edwards, 2007, p. 9). Diabetes mellitus is the leading cause of end-stage kidney disease, foot and leg amputations, and new cases of blindness in the United States (Ignatavicius & Workman, 2010, p. 1465-66). People with type 1
It is undeniable that the recent discovery of antibiotics and disinfectants in the past century is leading to the creation of increasingly dangerous antibiotic-resistant bacteria. Super bugs like Methicillin-resistant Staphylococcus have begun breaking out in hospital areas, killing more and more patients due to the lack of people following through with simple safety measures. In order to stop the creation and spread of antibiotic-resistant super bugs, proper precautions must be taken such as avoiding
In 1865, congress passed the thirteenth amendment, which was ratified on December 6, 1865. The thirteenth amendment abolished slavery in the United States permanently. It was thought by many African Americans that there would finally be peace, and that they too would be treated as fairly as the whites. This was sadly not the case. African Americans were brutally segregated and entrusted to hard times and conditions. Whites began to insist on racial segregation, which had been practiced before, and
