Determine the total heat transfer during the overall process

Mechanical Engineering

A piston-cypinder device contains 3 m^3 H2O at 6 MPa, 800 C (state 1). The system is cooled at constant volume to 180 C (state 2). The first process is followed by isothermal process ending with saturated liquid water (state 3). Determine:

a) The pressure of the system at state’s 2 and 3,

b) The total work done during the overall process,

c) The total heat transfer during the overall process.

Show these processes on P-v and T-v diagrams schematically with respect to saturation lines.

Criticize the heat exchanger design

Mechanical Engineering

It is proposed to cool 64?C air as it flows, fully developed, in a 1 m length of 8 cm I.D. smooth, thin-walled tubing. The coolant is Freon 12 flowing, fully developed, in the opposite direction, in eight smooth 1 cm I.D. tubes equally spaced around the periphery of the large tube.

The Freon enters at -15?C and is fully developed over almost the entire length. The average speeds are 30 m/s for the air and 0.5 m/s for the Freon.

Determine the exiting air temperature, assuming that soldering provides perfect thermal contact between the entire surface of the small tubes and the surface of the large tube.

Criticize the heat exchanger design and propose some design improvement.

Maladaptive Responses to Immune Disorders

Discussion: Maladaptive Responses to Immune Disorders

Maladaptive responses to disorders are compensatory mechanisms that ultimately have adverse health effects for patients. For instance, a patient’s allergic reaction to peanuts might lead to anaphylactic shock, or a patient struggling with depression might develop a substance-abuse problem. To properly diagnose and treat patients, advanced practice nurses must understand both the pathophysiology of disorders and potential maladaptive responses that some disorders cause.
Consider immune disorders, such as HIV, psoriasis, inflammatory bowel disease, and systemic lupus E. What are resulting maladaptive responses for patients with these disorders?
To prepare:
Review Chapter 6 and Chapter 8 in the Huether and McCance text, as well as the Yi, et al, article in the Learning Resources. Reflect on the concept of maladaptive responses to disorders.
Select two of the following immune disorders: HIV, psoriasis, inflammatory bowel disease, and/or systemic lupus E (SLE).
Think about the pathophysiology of each disorder you selected. Consider the compensatory mechanisms that the disorders trigger. Then, compare the resulting maladaptive and physiological responses of the two disorders.
Consider the types of drugs that would be prescribed to patients to treat symptoms associated with these disorders and why.
Select one of the following patient factors: genetics, gender, ethnicity, age, or behavior. Consider how your selected factor might impact the disorder. Then, reflect on how your selected factor might impact the effects of prescribed drugs, as well as any measures you might take to help reduce any negative side effects.
By Day 3
Post a brief description of the pathophysiology of the immune disorders you selected. Explain how the maladaptive and physiological responses of the two disorders differ. Then, describe the types of drugs that would be prescribed to patients to treat symptoms associated with these immune disorders and why. Explain how the factor you selected might impact the pathophysiology of each disorder as well as the effects of prescribed drugs. Finally, explain any measures you might take to help reduce any negative side effects.
Note: Post a (at least 500 word) response. Be sure to use evidence from the readings and include in-text citations. Utilize essay-level writing practice and skills, including the use of transitional material and organizational frames. Use the writing resources and the Discussion and Response Rubric to develop your post. Three credible references are required for this discussion post. A reference list is required. Use the most current evidence (usually less than or equal to 5 years old).

Should current nursing practices be changed?

Medicine / Nursing

Should current nursing practices be changed?

Research the evidence based literature for a study that has changed or verified current pediatric practice. Critique the study as to its strenth and validity. Can the findings be applied to pediatric settings? Should current nursing practices be changed?

Also a brief powerpoint of 4 to 6 slides should accompany it please let powerpoing be colorful

Employment Relations & Regulations

GOOGLE v. MICROSOFT

1. In this case, the parties eventually settled, and Dr. Lee went on to run the Google China initiative. If you were running Microsoft, what would you have done differently in this situation?

2. Considering that this is a common scenario, how do you recommend companies to respond in the future?

QUILL CORP V. NORTH DAKOTA

3. Based on the standards articulated in the case summary, should the state be allowed to impose a use tax on Quill even though it does not have a physical presence in the state?

4. Is this the right decision? Should a state be able to impose income taxes on a company whether or not it has a physical presence, as the state supreme court held? Or was the U.S. Supreme Court correct?

Discuss the gender gap in wages and the concept of comparable worth, including the practice of exceptioning.

Women have come a long way since we entered the workplace.  Unfortunately not enough. Forbes wrote in 2013,  “For more than a decade now, the comparison between the median earnings of full-time employed men and women in the U.S. has remained a stubborn 77%–that is, women earn roughly 77 cents on the dollar when stacked against the paychecks of white men” http://www.forbes.com/sites/meghancasserly/2013/09/19/the-geography-of-the-gender-pay-gap-womens-earnings-by-state/.

 

Women in science and medicine are also lagging behind. Common Health wrote this article yesterday: http://commonhealth.wbur.org/2014/09/nih-grants-10m-to-help-erase-research-gender-gap-but-is-it-enough

What are your  thoughts and your experiences?

Comparable worth refers to the notion that jobs that require equivalent KSAOs should be compensated equally.

1) Discuss the gender gap in wages and the concept of comparable worth, including the practice of exceptioning. Discuss how this situation may change in the future and how it may be affected by changes in the general workforce.

2) Discuss the influence of civil rights legislation on the structure and use of job analyses.
