Hydraulic Hoses Inc Produces Specialized Industrial Hoses For Application Such A

/in /by

Hydraulic Hoses, Inc produces specialized industrial hoses for application such as high-pressure hydraulics and the transference of highly corrosive materials. The company recently implemented an ABC system for three of its products and is interested in evaluating its effectiveness before converting to an ABC system for all its products. To perform this evaluation the company has compiled data for three products using both the traditional system and the new ABC system . The traditional system uses a single driver (direct materials cost). The ABC system uses a variety of cost drivers related to the activities used to produce the metal products. The three products involved in the trial run of the ABC system were D-13, K-17, and R-23. The following data relate to these products (attached)

Hydrocortisone Is An Over The Counter Ointment Commonly Used To Treat Eczema Ecz

/in /by

Hydrocortisone is an over-the-counter ointment commonly used to treat eczema. Eczema is a skin condition where a patch of skin becomes irritated and inflamed. It is estimated that approximately 15% of Canadians are affected by eczema at some point in their lives. The active ingredient in hydrocortisone cream is the hormone cortisol. 

Which of the following statements describes why hydrocortisone is an effective treatment for eczema?

Select one:

a. Hydrocortisone helps to suppress the skin inflammation by increasing the immune response.

b. Hydrocortisone helps to suppress the skin inflammation by decreasing the immune response.

c. Hydrocortisone helps to fight off the skin infection by decreasing the immune response.

d. Hydrocortisone helps to fight off the skin infection by increasing the immune response.

Hydrogen Cars Versus Ice Cars 16 Points A Hydrogen Fuel Cell Electric Passenger

/in /by

Hydrogen Cars versus ICE Cars (16 points)

A hydrogen fuel cell electric passenger vehicle (FCEV sedan) has the following properties:

  1. Hydrogen Fuel Manufacturing Pathway (raw material phase included): Reformation of North
  2. American natural gas into compressed hydrogen at a central steam methane reformation (SMR) plant; includes liquefaction and re-gasification
  3. For details about the carbon intensity of this pathway (note that all carbon intensity pathways are given in gCO2e/MJ of hydrogen fuel):
  4. California Environmental Protection Agency Air Resources Board, no date, “Detailed California Modified GREET Pathway for Compressed Gaseous Hydrogen from North American Natural Gas.” https://www.arb.ca.gov/fuels/lcfs/121514hydrogen.pdf, accessed 2/23/2019 at 5:00pm
  5. FCEV Efficiency: 81 miles/gallon (mpg) of gasoline equivalent or ~ 0.66 miles/MJ of hydrogen fuel
  6. Total Vehicle Manufacturing + Maintenance Carbon Emissions: 11.8 metric tons CO2e
  7. Total Vehicle carbon from infrastructure construction and operation: 11.20 g CO2e/PMT.
  8. Total vehicle lifetime miles: 160,000 miles

Note: PMT refers to passenger miles traveled.

a) Use this information to calculate the life-cycle vehicle carbon emission factor for the FCEV in gCO2e/PMT. (Assume an average vehicle occupancy of one passenger, and for simplicity, you can neglect end-of-life emissions. (6 points) 

b) From your calculated emission factor, calculate the life-cycle percent CO2e savings from driving a FCEV as opposed to a typical one-passenger 35 mpg internal combustion engine sedan across various stages of each vehicle’s life-cycle as well as in total. The life-cycle stages that you should consider are: fuel production + manufacturing, vehicle manufacturing + maintenance, vehicle use, and infrastructure construction and maintenance. (hint: use http://www.transportationlca.org/tlcadb-passenger.php to find life-cycle data regarding the 35MPG sedan) (10 points)
