A SALMONELLA OUTBREAK INVOLVING 107 CONFIRMED AND 51 PROBABLE CASES OCCURRED IN DODGE COUNTY, WISCONSIN.   THE ILLNESS WAS CAUSED BY EATING RAW BEEF COMMONLY KNOWN AS STEAK TARTARE. INVESTIGATION SUSPECT INADEQUATE CLEANING OF THE MEAT GRINDER MAY HAVE BEEN THE CAUSE OF THE ILLNESS. EMPLOYEES OF THE BUTCHER SHOP WHERE THE GROUND BEEF WAS PURCHASED INDICATED THE PARTS OF THE GRINDER WERE CLEANED AND SANITIZED AT THE END OF EACH DAY. HOWEVER, THE AUGER HOUSING, WHICH WAS ATTACHED WITH NUTS AND BOLTS COULD NOT BE EASILY REMOVED FOR CLEANING AND SANITIZING. EMPLOYEES INDICATED THEY HAD BEEN INSTRUCTED NOT TO REMOVE THE AUGER HOUSING FOR CLEANING. QUESTION: 1. WHAT WOULD BE THE POSSIBLE CAUSE OF SALMONELLA OUTBREAK? 2. HOW COULD THIS OUTBREAK HAVE BEEN PREVENTED? 3. IS THERE ANY ALTERNATIVE MACHINE TO BE USED IN GRINDING THE MEAT?

I need help correcting this problem (incorrect attempts are attached). Please step-by-step.

a) Between EMG activity and force output, which changes with grip spacing and which stays constant? b) Which one of the principles below explains the relationship between grip spacing and force output? -Force-velocity (load-velocity) -Length-tension -Frequency-tension c) Explain the difference in sarcomere overlap as spacer width increases.

Produce a written report documenting: the choice of sensors, sensor evaluation, the developed processor/measurement system, and overall system performance of a wire cutting system. Your system should facilitate the measurement of: - Cable remaining on the feed spool/reel -Presence of cable in the cutter assembly mechanism -Measurement of cable length (length extended from the cutting side) -Detection of object (human hand) within the safe working distance of the cutter (300mm)

What type of CAD software could be used to test the medical scaffold made out of TPU that will be printed using stereolithography (SLA). The medical scaffold will be surgically implanted around the pancreas to enable the infusion of Islet beta cells which are encapsulated within the scaffold to provide diabetic patients with a functional pancreas. E.g. hydrostatic pressure testing/torsion tests What other type of physical testings should be taken?  E.g. Brunauer–Emmett–Teller (BET) test to check the porosity of the material

1. Define the 3 mediums used for automation (Pneumatic System, Hydraulic System, Electronic/Electrical System) and2. Discuss the advantages and disadvantages of each system. Include examples of where are this system is used.3. Differentiate the types of actuators (Pneumatic Cylinder, Hydraulic Cylinder, and Electrical Cylinder). What are the advantages and applications of each

Bolts installed on a production line are tightened with automatic wrenches. They are to be tightened sufficiently to yield the full cross-section in order to produce the highest possible initial tension. The limiting condition is twisting off the bolt head during assembly. The bolts have a mean twisting off torque of 20 Nm with a standard deviation of 1 Nm. The automatic wrenches have a standard deviation of 1.5Nm. What mean value of torque wrench setting would result in only 1 in 500 twisting off during assembly? Give a rough estimate only. A unit has a constant failure rate of 0.3% per 1000 hours. What is its MTBF? What are the probabilities of the unit successfully completing missions of 10000, 100000 and 1000000 hours? Give a rough estimate only.

Course: Metrology Distinguish between “interference fit” and “Clearance fit”.

Assume your equipment is operated 300 workdays for 16 hours per day and with a known MTBF of 240 hours. Failure costs are estimated at $12,000 per failure.  A PM option would cost $750 per scheduled routine.  Could you justify the PM program if performing the PM routine every 100 hours reduces the number of failures by 50% ?   What are the net savings of adopting the PM program?

Write a brief report detailing the development of safety belts in cars. When was the first safety belt designed? Which was the first car manufacturer to incorporate safety belts as standard items in its cars? Write between ½ to 1-page report and make sure it is in your own words. Also, list your references using the Automatic Referencing & Citation with MSWord in IEEE style.
