Effect of temperature on the rate of reaction between magnesium and hyd

Effect of temperature on the rate of reaction between magnesium and hydrochloric acid Apparatus: Magnesium strips (5cm) Hydrochloric acid Water bath Clamp x 3 Clamp stand x3 Ruler Measuring cylinder (100ml) Measuring beaker (50ml) x2 Rubber tube Rubber bung Gas syringe Wire wool Stop clock Aim: My aim is to find out if heating the hydrochloric acid affects the rate of magnesium and hydrochloric acid. Prediction: I predict that the heating the hydrochloric acid will effect it as heating is one type of changing the rate of reaction. Method: Get three clamps and clamp stands from the cupboard, and set them up and get a water bath and set it up to the right temperature (20-80) and then let it get to the right temp get a gas syringe form the tray and set the up to one of the stands and then measure out 30ml of hydrochloric acid and pour that in to the 50ml measuring beaker and then place that in to the water bath, repeat that with the other measuring beaker. Measure out 5cm of magnesium ribbon with the ruler and clean as much of magnesium oxide of as possible and, place a rubber tub...

Radiation Therapy

1. What concepts in the chapter are illustrated in this case? What ethical issues are raised by radiation technology? Basic concepts that are covered in this case are responsibility, accountability and liability. Ethical issues that are raised by radiation technology is when scientist is finding ways to use radiation therapy to destroy cancerous cells while making sure that healthy cells are not being harmed. An incident occurred where Mr. Jerome-Parks â€Å"experienced deafness and near-blindness, ulcers in his mouth and throat, persistent nausea, and severe pain. (Laudon, 2012, p. 131). Organizations did not take the time to properly train doctors and medical technicians therefore incidents like Jerome-Parks happens. The machines that are used to ‘cure’ patients are not being appropriately updated and watch carefully. In this case study we can see that the technicians are not being fully responsible and being careless, and doctors that are not getting the full trainin g for operating the machine. 2. What management, organization and technology factors that was responsible for the problems detailed in this case?The management, organization and technology factors were responsible for the problems detailed in this case because they failed to provide extensive training for doctors, technicians, and machine operations as well as insufficient staffs. They should have thought of creating a mandatory checklist for employees each time the machine was being used. The lack of knowledge on the machines, the lack of reporting these incidents for future references instead the doctors and technicians do not troubleshoot the problem unless it is serious and by that time the patient(s) is already injured.The machines were not well designed, there was software glitch and â€Å"the complexity of new Linear accelerator technology has not been accompanied by with appropriate updates in software† (Laudon, 2012, p. 132). 3. Do you feel that any of the groups inv olved with this issue (hospital administrators, technicians, medical equipment, and software manufacturers) should accept the majority of the blame for these incidents? I feel as if they are all responsible for this issue because if the medical equipment, software manufacturer and technicians were the first people who would be experiencing the machine.The software manufacturer designed the software so they should have known if there was any error that was missed during the trial and error stage. If there was they should’ve continued with more research until the software was nearly perfect because it is what operated the entire machine. The software was the main source of machine to operate because those software engineers were hired for a reason and they had responsibility in executing the errors and debugging them. This also would go on to the medical equipment and technicians because these technicians should already have knowledge on what is right and what is wrong.Technici ans are the one that tries out the machine at the hospital first they are the one that have the main knowledge on how these machines should be operating. All these three should be responsible for this issue since they are part in creating the machine and testing it out. 4. How would a central reporting agency that gathered data on radiation-related accidents help reduce the number of radiation therapy errors in the future? Having a central reporting agency that gathered data of radiation-related accidents could prevent future overdoses, misadministration, and deaths or near deaths.These data can train future and present doctors from doing these incidents, allows the agency to monitor the use of the machine and especially creates a safety environment. If these accidents were to occur more than once than the managers are the MIS could take in the machines for a more detailed examination, changing the policy and procedures. Also reporting the radiation therapy errors can used to teach future doctors, technicians, medical operators about it so they would not make the same mistake again. At the same time this can save many lives that was once put into danger due to the lack of knowledge, carelessness, and laziness. . If you were in charge of designing electronic software for a linear accelerator, what are some features you would include? Are there any features you would avoid? If I were in charge of designing electronic software for a linear accelerator some features I would include: a check list that is embedded within the machine ensuring that everything goes smoothly, a safety button which allows the machine to alert the doctor or technicians that something went wrong and will automatically shut down if the machine seems to malfunction that can do harm to a patient.Making sure that the software is doing its job in saving people’s lives, the software will go through multiple of examination until it is working at its potential. Every time the system seems t o malfunction it will be sent back to the manufacturing for fixing. I would avoid what happened to those patients that died because of the manufacturer’s error. Anything that was at fault will be avoided and things will be done properly and precisely to ensure every part of the machine is working. Work Cited Laudon, Kenneth and Laudon, Jane. (2012).

Charlie A Prisoner of the Cave - 989 Words

Plato, one of the most well-known philosophers in the ancient Greece, wrote an ultimate allegory known as â€Å"The Allegory of the Cave†. It is about a man coming out of a cave after being chained as a prisoner for his entire life and what he goes through upon reaching surface. The ideas presented in â€Å"The Allegory of the Cave† are very similar to the ideas presented in Daniel Keyes’s novel, Flowers for Algernon. He used an excerpt from the metaphor to start his novel. In Keyes’s novel, a 32 year old intellectually delayed man name Charlie Gordon undergoes an operation that makes him a genius. Charlie learns many life lessons such as a person’s right to live and the development of social skills. The three main time periods Charlie experiences throughout the novel: before intelligence, during intelligence, and after intelligence connects to Plato’s â€Å"Allegory of the Cave† At the beginning of Flowers for Algernon, Charlie could only see one side of things that he is exposed to; similarly, the prisoners of the cave could only see shadows. In â€Å"The Allegory of the Cave†, Socrates says to Glaucon , â€Å"The truth would be literally nothing but the shadows of the images† (Plato 1). Being chained limits the prisoners to see and hear anything but the shadows on the wall and the echoes bouncing off of it. However, shadows are never the truths; they are an exaggerated version of the actual person or self. What they see is a false image, but they believe it is true because it is what theyShow MoreRelatedAnalysis Of Flowers For Algonnon By Platos Flowers For Algernon1228 Words   |  5 Pagesof the Den† by Plato, he writes about prisoners chained in a cave. They all believe in one shadow, without any other truth contradicting them. But one day a prisoner was set free and let out of the cave. This prisoner sees the â€Å"sun† or the real truth, which is hard to believe at first, but o nce the truth is accepted the prisoner can’t believe they thought something any other way.
