Explain the mechanism of temper embrittlement! (How, what temperature, the impact of alloying element and how to avoid it)

2: We heat treated a 2205 duplex stainless steel at 1100°C resulting in ferrite/austenite content of 50-50%. The pitting resistance temperature is 80°C. We heat-treated another piece at 800°C for 10 min and the pitting temperature dropped to 60°C. As the composition of the alloys is the same, so we have the same PRE in the alloy.

a) Why do we have a reduction in corrosion resistance? Explain based on the PRE.

b) If we use the material in a corrosive environment and loaded condition, what types of failure are you expecting to occur?

The hidden meaning in “the midsummer nights dream”

During the last five years average daily occupancy at Autumn Acres nursing home has slid from 125 to 95 even though Autumn Acres has cut its daily rate from $125 to $115. Do these data suggest that occupancy would have been higher if Autumn Acres had raised its rates? What changes in non-price demand factors might explain this? (There have been no changes in supply. The number of nursing home beds in the area has not changed during this period.)
2.Why is the demand for healthcare products usually inelastic? Why is the demand for an individual firm’s healthcare products usually elastic?
3.If the income elasticity of demand is 0.2, how would the volume of services change if income rose by 10 percent?
4.Your boss has asked you to describe how the demand for an over-the-counter sinus medication would change in the following situations. Assuming the price does not change, forecast whether the sales volume will go up, remain constant, or go down.
1. The local population increases.
2. A wet spring leads to a bumper crop of ragweed.
3. Factory closings lead to a drop in the area’s average income.
4. A competing product with a different formula is found to be unsafe.
5. A research study is published showing that the medication causes severe dizziness.
6. The price of another sinus medication drops.

Affordable Care Act on long term care services and reimbursement in chapter 9; specifically by way of how payments have been bundled, thereby encouraging higher levels of health-system-integration between LTCs and larger healthcare organizations and networks. However, beyond that, the impact of the ACA on the long term care health industry sector is described as unclear. The impact on consumer choice–as influenced by regulation, financing, and politics–along with the move toward Medicaid managed care, are highlighted as areas of concern, but with little detail and insight.
Today, we are in a time of even greater uncertainty given some current legislative interest – albeit somewhat diminished following an unsuccessful attempt in late 2017 – to further revise broad-sweeping health policy at the federal level… for instance, passing a new bill that would effectively replace the ACA. Details on the new provisions are often sparse and described in partisan terms, and are actively in fluid negotiations.
