Where in the US is AMD an issue? What treatment technologies can be used to remediate sites which have been impaired by AMD? Have any of these technologies been used in Pennsylvania? How can AMD be prevented?

QUESTION : Can u suggest me 6 EMERGENCY RESPONSE TEAM(ERT) related to chemical plant and their responsibilities.

AS SOON AS POSSIBLE.. THANK U IN ADVANCE.

Subject - OSH

What are the main chemical reactions involved in AMD formation?

What is the “initiator reaction” and the “propagation cycle”?

Why is this cyclical nature (regeneration of Fe2+) problematic? How do microbes play a role in these reactions?

What is “yellow boy”? Oxidation of Fe2+ is very slow at low pH values. Why does this reaction occur then in acidic environments?

For cell culture, various laboratories use different volumes of culture medium in their culture flasks according to their conventions. However, many do not consider how this might affect the diffusion time of O2 from the gas/liquid interface to the cells attached to the bottom of the flask. To address this, it is useful to have an understanding of how the O2 diffusion time might be influences by the volume of medium added. A typical cell culture flask has a surface area available for cell attachment of 75 cm2 , therefore the height of medium, thus the diffusion distance will be a function of the volume of culture medium added. Cell culture is typically done at a temperature of 37 ºC. a) Calculate the diffusion time for O2 through culture medium from the gas/liquid interface if the height of medium (distance from the gas/liquid interface to the bottom of the culture dish) is 4 mm. Use the Einstein's approximation equation to determine your answer and cite the reference for the O2 diffusivity value you used in your calculations. b) Produce a plot of the O2 diffusion time as a function of culture medium volume for volumes in the range of 7 to 15 ml. c) If you wanted to standardize your laboratory’s practice in cell culture by keeping the height of culture medium the same (at 1.2 mm) for whatever vessels you use to culture cells, what volumes would be required for: - Standard round cell culture dishes with 35, 60, and 100 mm diameter. - For flasks, standard surface areas are 25, 75, and 175 cm2 . Show calculations for one of the conditions and present your results for all of the conditions in a table

Create a 1-page fact sheet that your healthcare organization could hypothetically use to explain the health or nursing informatics policy/regulation you selected. Your fact sheet should address the following:

• Briefly and generally explain the policy or regulation you selected.
• Address the impact of the policy or regulation you selected on system implementation.
• Address the impact of the policy or regulation you selected on clinical care, patient/provider interactions, and workflow.
• Highlight organizational policies and procedures that are/will be in place at your healthcare organization to address the policy or regulation you selected. Be specific.

Is there any trend between polymer structure and diffusion of a gas through the polymer? Rationalize your answer with 3 key points/facts/ideas.

Why are ceramics brittle? Can your answer also explain polymer behavior below its glass transition temperature? Why or why not?

(a) Derive Freundlich and Langmuir isotherm equations.

(b) An aqueous solution containing a valuable solute is colored by a small amount of an impurity. Before crystallization, the impurity is to be removed by adsorption on a decoloring carbon which adsorps only insignificant amount of the principal solute. Equilibrium data at constant temperature is as follows:

It is desired to reduce the color intensity to 10% of its original value (9.6)
(1) Find out Freundlich adsorption isotherm
(2) Determine the quantity of fresh carbon requirement per 100 kg of solution for a single stage operation.

"We are made of starstuff.”
― Carl Sagan, Cosmos

What did Carl Sagan mean when he made this famous statement? Write about your interpretation of this statement:

• Is it literal or figurative?
  • Make sure you use the proper dictionary definition of "literal" as people often use it to mean the exact opposite! Look it up if you aren't sure!
• Where did the material that Earth is made out of -- the silicon and carbon and iron and so forth -- come from?
• What implications does this have for life on planets around other stars, if there is any?

How do you perform adiabatic flash calculations?

Which of the following is NOT TRUE of Thomas Burnet’s 1684 book “The Theory of the Earth”?
A. Time was not constant, as suggested by Sir Isaac Newton
B. The water for Noah’s flood came from within the Earth
C. The Earth would end up as a star after the Day of Judgement
D. It encouraged an allegorical interpretation of Genesis
