Unit VI Journal Weight: 2% of course grade Grading Rubric Instructions What do you think are the pros and cons of local exhaust ventilation systems and general dilution ventilation systems? Provide at least one example of an occupational setting where you have seen a general dilution ventilation system effectively reduce exposures and one example of an occupational setting where you have seen a general dilution ventilation system not provide effective reduction of exposure requiring a local exhaust ventilation system to be installed.Your journal entry must be at least 200 words in length. No references or citations are necessary Unit VI Scholarly Activity Weight: 10% of course grade Grading Rubric Instructions This assignment will consist of two parts. Both parts will be compiled into the same document for submission. Part I: Thus far at Acme Automotive Parts (AAP), you have determined that controls are required in the paint booths, at the hand-welding stations, and on the machining lines. You have also determined that you cannot substitute any alternate chemicals in these areas because of requirements from your clients. You decide to use general dilution ventilation for the machining lines and local exhaust ventilation systems for the paint booths and the hand-welding stations. Complete the following tasks. For the general dilution ventilation used in the machining lines: Discuss why you believe a general ventilation system is appropriate for this operation. State where you would you place the fans associated with the ventilation system. Explain how you would test the effectiveness of the ventilation system. For the local exhaust ventilation systems: Describe the local exhaust ventilations (LEVs) you would use for each area (paint booths and hand-welding stations). Choose a hood type for each of the two LEVs. Calculate the flow rate that would be required if you placed the LEV for the welding operation 24 in. from the weld and desired a capture velocity of 100 ft per minute (ft/min) given W=12 in. and L=24 in. for any of the three hood types. Discuss any barriers you might face in implementing the use of the LEVs for these two operations. Part II: You also determined that engineering controls are needed for the hydraulic press area.        Discuss some types of engineering controls that might be implemented for the hydraulic press area. Describe the information you might require prior to designing engineering controls for the hydraulic press area. Explain how you would evaluate the effectiveness of the engineering controls for this area.

One of the greatest scientific developments of the past 150 years is the discovery of antibiotics. For some basic background on antibiotics, listen to this very brief Centers for Disease Control (CDC) podcast about antibiotics:http://www2c.cdc.gov/podcasts/player.asp?f=10055 There is, however, a dirty little secret about Alexander Fleming and his discovery: it was an accident! As Fleming worked in his lab in the late 1920s growing disease-causing bacteria in tiny petri dishes, he got a little sloppy by leaving the petri dishes uncovered too long. One story even suggests that he may have sneezed into one of his petri dishes. Regardless of the exact cause, what resulted was a mold infestation on some of his bacterial dishes. However messy Fleming was, he was also smart enough to see that the mold infestation was killing off the bacteria he was studying. Completely by accident, he had found something that killed disease-causing organisms.Such "happy accidents" are not uncommon in science. Some notable examples include aspartame (NutraSweet) which was discovered by a drug chemist who forgot to wash his hands. Even Isaac Newton benefited from a little accidental inspiration when he (supposedly) came up with a description of the concept of gravity after being knocked on the head by a falling apple. Scientists, like everyone else, make mistakes but, the best scientists use their mistakes and learn from them.Reflect about the famous Louis Pasteur quote: "Chance favors the prepared mind," as well as what you learned about scientific inquiry throughout the course. Then, during the week, address the following:What examples of learning by "happy accident" have you experienced in your own life?What do you think it means for a person (especially a scientist) to have a "prepared mind," as Pasteur describes?How can a person prepare his or her mind to be open to chance within any particular discipline? What roles might education, job experience, and life experience play in creating a prepared mind?What about science makes it particularly good at allowing people to analyze their accidents?What are some risks associated with research that involves chance? [Hint: Use your Reading this week and consider the risks associated with stem cell research, cloning, gene therapy, HIV.] Are there circumstances when research should not be conducted due to risks or are there ways to reduce risk?This discussion is to be 300-350 words thank you
