Identify three primary types of energy that power your home as well as all of the homes in your community. You may find this information on your community Web site or the Web sites of the local power companies. For example, your community may use electricity and solar panels.

It is easy to criticize society for not using renewable resources, but in reality, how difficult would this transition be? What processes and procedures would be involved? How would such a transition be made?

The purpose of this assignment is for you to consider what type of energy your neighborhood is currently powered by and what it would really take to convert this source to a renewable one. How much would it take to switch your community to a renewable resource and what would this mean for the environment?

For the assignment, complete the following:

  • Identify three primary types of energy that power your home as well as all of the homes in your community. You may find this information on your community Web site or the Web sites of the local power companies. For example, your community may use electricity and solar panels.
  • Explain how the sources of energy you identified impact the environment. Consider the following:
    • Does the use of these types of energy resource have a negative impact on the environment in your area?
    • Does your community have nuclear waste to dispose of?
    • Has your community always used these three power sources? If so, how do you feel this has impacted the environment over time?
    • How much of an impact have these sources of energy had on local air and water quality?
  • Considering the current source(s) of power available, determine how much energy your house uses each month. You can find this information on your monthly energy bill.Calculate your annual usage for a year. Using this value, estimate the energy consumption for your community. The US Census Bureau is one resource you can use to estimate the number of households in your community.
    You can use the following formulae for this calculation:

    (monthly energy usage) × (12 months per year) = (household energy usage per year);
    (yearly energy estimate for your house) × (estimated number of houses in your community) = (estimated yearly energy use for your community)
    The following is an example of the above calculation:
    52.8-kilowatt hours (kwh) per month × 12 months = 633.6 kwh;
    633.6 kwh × 200 houses in your community = 126,720 kwh

  • Recommend a realistic, renewable resource to power your community, using your calculated power needs. Consider the following sources: hydropower, solar power, wind turbines, and geothermal energy.
    • Which source would be the best for your community?
    • Justify your choice based on the kind of resources that are available, how much power these alternative sources can produce, and your estimated energy demands for the community.
  • Having recommended an alternative power source, conclude by addressing the following:
    • How realistic is this alternative power source for your community?
    • How will people in your community respond to energy conversion? Will they support it or be against it? Give reasons.
    • How expensive would it be to convert to the alternative power source you recommended? How would this new source impact the environment?
    • What organisms would benefit most from this conversion?

Support your statements with appropriate examples and approximately 4–6 credible resources.

Write an 8–10-page paper in Word format. Apply APA standards to citation of sources.

Choose a living organism, and explain how it illustrates each of the characteristics of life.

What does it take to be a living organism?

Living things share eight characteristics (listed in Chapter 1 of your textbook on page 19). A living thing grows, undergoes metabolism, responds to its environment, reproduces, passes DNA to the next generation, maintains homeostasis, changes over time, and is made up of cells. A nonliving thing may seem to do one or more of these things, but to be classified as living, all eight characteristics must be present. Sometimes, you may see something that seems alive but is not. Water, for example, moves, responds to temperature, dissolves substances, erodes rocks, and so on, but it does not have DNA and is not made up of cells. Other times, you may see a thing and think it cannot be alive, yet it is. Coral looks like a rock, but a coral reef is actually made up of millions of tiny animals.

Focus your discussion on only 1 of the following topics:

  • Choose a living organism, and explain how it illustrates each of the characteristics of life.
  • Research and describe an organism or cell in which all 8 characteristics are not obvious. For example, coral looks like it does not move, red blood cells do not reproduce and have no DNA, frogs freeze in the winter and it, therefore, seems as if they do not maintain homeostasis, and so on. Describe the missing feature, and explain how this organism still meets the criteria of a living thing.
  • Compare a living thing with a nonliving thing of your choice that has some of the characteristics that define life. For example, a car exhibits metabolism (burning gas and producing heat), a characteristic of life, but is not alive because it cannot reproduce.
  • Compare and contrast the following pairs based on the 8 characteristics that define life:
    • A rock and a snail
    • A lamp and a tree
  • Discuss some of the characteristics that fire shares with living things (it can grow, it metabolizes, and so on).

Utilize at least 1 credible source to support the arguments presented in your post. Make sure you cite appropriately within your narrative and list the reference(s) in APA format.

Determine the mole fraction xA and molar ratio XA of TCE in the wastewater

 A clarifier in a wastewater treatment plant contains wastewater with a bulk concentration of TCE of 0.010 kmol m-3.

The clarifier operates at 1.0 atm and a constant temperature of 20 oC. The overall diameter is 2.0 m and it is enclosed to contain the (sometimes smelly) gases which are emitted from the wastewater. Fresh air is blown into this enclosure to remove the gases emitted from the clarifier and is then sent to an incinerator. The TCE content in the gas leaving the clarifier is 4.0 mol %. The liquid film mass transfer coefficient for the clarifier is estimated as kx=0.200 kmol m-2s-1 and the gas film mass transfer coefficient is ky=0.0001 kmol m-2s-1. Assuming that this wastewater has the same molar density and TCE equilibrium relationship as in Question 1, determine the following:

(a) Determine the mole fraction xA and molar ratio XA of TCE in the wastewater

(b) What would be the mole fraction yA* of TCE in the air, if in equilibrium with 0.010 kmol m-3 TCE in the wastewater? (i.e. saturation mole fraction in the gas phase)

(c) What would be the mole fraction xA* of TCE in the wastewater, if in equilibrium with 4 mol% TCE in the air? (i.e. saturation mole fraction in a liquid phase)

(d) Plot Henry’s law relation y*=mx determined in Q1, and indicate xA, xA*, yA, yA* for the clarifier on that plot. What will be the direction of mass transfer of TCE? (i.e. from wastewater to air, or from air to wastewater?) 8 marks (e) Determine the overall mass transfer coefficients Kx and KL

(f) Determine the overall mass transfer coefficients Ky and KG (kmol m-2 s-1 atm-1). 6 marks (g) Determine the rate of mass transfer of TCE to/from the surface of the clarifier

(h) Determine xAi and yAi, the mole fraction of TCE in the liquid and vapor phase, respectively, at the water/air interface. Plot these values on a graph from Q2d.

(i) If the concentration of TCE in the wastewater entering the clarifier is 0.050 kmol m-3, what flowrate of wastewater (m3/h) is required to ensure that the concentration of TCE in wastewater leaving the clarifier is 0.01 kmol m-3? If the depth of liquid in the clarifier is 4 m, what average residence time is required for the wastewater?

What should be the basis of the HR department’s goals regarding their responsibilities to support management during the screening, hiring, and retention stages of employees?

In organizations today, the emphasis is on performance and the contribution of a function to the success of that organization. Senior managers demand evidence of effectiveness and efficiency. They need objective ways to measure achievement and strategically plan for the future. The heart of success at BANKS Industries is the HR department’s responsibility to guide managers in their ability to screen, hire, and retain quality employees.

As part of the BANKS management team, you have been assigned to a task force that is considering how the HR department should be strategically involved as the BANKS workforce becomes more diverse and experiences expansion. As part of a preliminary discussion, you have been asked to generate a report on the following issues:

  • What should be the basis of the HR department’s goals regarding their responsibilities to support management during the screening, hiring, and retention stages of employees?
  • How do these goals strategically align with success for BANKS?
  • How should the HR department interact with and implement these goals for management and employees?
  • How will you measure whether the HR department has been successful in achieving its goals? Based on your research, what assessments can be used to determine success?

Explain the topic you are addressing and your position on it. Provide a preview of your paper and a statement of your thesis in your opening paragraph

This final assignment is designed to involve all of the main skills that you have learned during this course. In particular, your paper should demonstrate the ability to construct a deductively valid or inductively strong argument, clearly and accurately explain your reasoning, use high-quality academic sources to support the premises of your argument, fairly and honestly evaluate contrary arguments and objections, and identify fallacies and biases that occur within the arguments or objections presented.

You will continue to build on the arguments that you are presented in your previous two papers. In particular, you will present a final improved version of your argument for your thesis that you begin for the Week One Assignment and fully address the objection that you developed for your Week Three Assignment. You will need to research a minimum of three scholarly sources from the Ashford University Library. (For further information about discovering and including scholarly research, take a look at the FindIt@AU Tutorial instructional resource.)

Write: in your paper

  • Explain the topic you are addressing and your position on it. Provide a preview of your paper and a statement of your thesis in your opening paragraph. [Approximately 100 words]
    • For help crafting a good thesis statement, go to the       Ashford Writing Center.
  • Present your main argument for your thesis in standard form, with each premise and the conclusion on a separate line. Clearly, indicate whether your argument is intended to be inductive or deductive.      Follow up the presentation of your argument by clarifying the meaning of any premises that could use some explanation. [About 150 words]
    • If your argument is deductive, then it should be valid       (in the strict logical sense of the word); if it is inductive, then it should be strong. Make sure to avoid committing logical fallacies within your argument (e.g., begging the question). Additionally, the premises should be true, to the best of your knowledge. If one of your premises has a pretty obvious counter-example, then you should either fix the argument so that it does not have this flaw or later, in your paper       (steps three through five) you should address the apparent counter-example (showing that it does not really refute the truth of your premise). Arguments that are not valid, not very strong, commit fallacies, or that have counter-examples that are not adequately addressed will not receive full credit.
  • Provide supporting evidence for the premises of your argument. [Approximately 350 words]
    • Pay special attention to those premises that could be seen as controversial. Evidence may include academic research sources,       supporting arguments (arguments whose conclusions are premises of the main argument), or other ways of demonstrating the truth of those premises. This section should include at least one scholarly research source.
  • Explain a strong objection to your argument.      [Approximately 250 words]
    • Study what people on the other side of this question think about your reasoning and present the best possible objection that someone could have to your argument. Do not commit the straw man fallacy here. Reference at least one scholarly-research source. See the “Practicing Effective Criticism” section of Chapter 9 of the course text for more information.
  • Defend your argument against the objection.      [Approximately 200 words]
    • Once you have presented the objection, indicate clearly how you might respond to it. It is acceptable to admit that reasonable people might disagree with you or that there might be an area in which your argument could be further strengthened, but you should do your best to explain why your argument is sound or cogent despite the objections.
  • Provide an appropriate conclusion. [Approximately 75      words]
    • For guidance on how to develop a conclusion see the       Introductions and Conclusion resource from the Ashford Writing Center

Explain WHY the topic is important or interesting to YOU? WHY should it be of interest or importance to the reader? 

Ethics refers to what is morally right or wrong; a standard of how one should behave. Morals are beliefs of what is correct and not correct based on our family, religion, and social influences. Although ethics are personal, they are also decided upon by professional or governmental organizations. Ethics can also be called “Shades of Gray” because there are oft times when there is no clear right or wrong choice.

For your project, you need to pick a healthcare related ethical issue that interests you; research both sides of the issue, form your own opinion about the issue and present it in a well thought out response.

Select a topic. Examples are genetic screening, body modification, organ transplantation, life support, genetic engineering, blood transfusions, confidentiality, euthanasia, prescription drugs, recreational drug use, stem cell research, government health regulations (for examples: school lunches or fast food nutrition), etc. Excluded from your options are ethical issues that deal with abortion and/or contraceptives. These topics are not discussed in BSC 251. If a student selects either, their paper will not be graded and a zero will be awarded to the student.

For example:

· Do we have a responsibility to provide healthcare to less fortunate people (government health regulations)?

· Is it wrong to divulge a patient record (confidentiality)?

· Should we try to keep people alive at all costs, no matter what their physical or mental condition (life support vs. euthanasia)?

· Do you think that drugs are being overprescribed and overused to deal with psychological and emotional problems?

· Should individuals with a known genetic disorder or trait have children?

· Why do you think our society is turning increasingly to pharmaceutical solutions for emotional and behavioral problems? For example, Ritalin and other drugs are increasingly being prescribed to deal with children’s behavioral and emotional problems as “attention deficit hyperactivity disorder.” Some people believe that this is a dangerous trend, that these drugs may have long-term consequences for children, and that there is no scientific basis for the diagnosis of the disorder for which the drugs are prescribed. What do you think?

· Think about HIV prevention efforts in your own community. What kinds of obstacles do educators and health care workers face in combating HIV in your community? What would you propose as an effective, unique way to teach you and your peers about HIV safety and prevention?

· Pros and Cons of genetic engineering stem cell research.

· Is drinking alcohol harmful to an unborn baby?

· Is human cloning acceptable?

Introduction: Briefly introduce and outline your ethical issue. Why is it an ethical issue?

Explain WHY the topic is important or interesting to YOU? WHY should it be of interest or importance to the reader?

The body of Paper: The body of your paper should include discussion of the following:

Give background information, and then discuss the pros, cons, and your opinion on your topic (describe the decision that you would make in this situation and explain why).

Text must include the following:

 

  • One side of the       issue
  • The other side       of the issue

The body of the paper should reflect a clear understanding of these subjects written in your own words. No headings or subheadings are allowed within the body of the paper.

Conclusion: In your own words, explain your reaction to the information you learned from your research. Do NOT just restate your discussion or facts from the paper. Your conclusion should be personal, based on what you learned while researching this paper.
