ENGR 381 Contemporary Issue Assignment
Review and Reflection on Hydraulic Fracturing
DUE DATE: 15th December
Thermodynamics is fundamentally a subject about energy, which affects our lives in many
different ways. The availability of energy impacts our lifestyle, environment, economy, and
health. One of the primary controversial current topics related to energy is hydraulic fracturing.
Our contemporary issue project this semester will focus on hydraulic fracturing, which is a
controversial technique for harvesting natural gas (and other hydrocarbons) from the earth. This
project has two parts, the first being related to objective aspects of hydraulic fracturing and the
second being subjective to yourself and your own values. The final product of this project will
be a formal written report. The breakdown for the report will be as follows:
1. Part 1: An overview of hydraulic fracturing (or fracking) (2-3 pages, 12 point font, single
a. A technical description of fracking
b. An overview of benefits, potential and realized
c. An overview of drawbacks, potential and realized
d. What biases do you detect?
e. Are there discrepancies in your resources?
2. Part 2: Your view on hydraulic fracturing (1-2 pages, 12 point font, single spacing)
a. Evaluate this technology from your personal perspective
b. Engage your values and beliefs as well as engineering ethics and virtues
c. Being as realistic as you can, what is your final recommendation regarding this
technology? Try to be convincing.
This project will require the gathering of information from a variety of sources. You should
include at least one from each of the following:
1. Documentary films
2. Mainstream newpaper articles
3. Blogs/editorial websites
4. Scientific articles
5. Editorials/articles/position statements from engineering societies (e.g. ASME, AIAA,
ACS, etc.)
6. Business magazines
Look for bias (implicit or explicit), and comment on it in your writing. Cite your research
materials throughout your report. Find your own references; I don’t expect to see the same set of
references for any two reports. Give proper citation to any figures used from your sources. See
the included materials on engineering ethics and virtues, and cite these as you make your
arguments in part 2.
Grading criterion: Quality of writing (including the use of citations) (25%), completeness of
background in part 1 (25%), articulation of your point of view in part 2 including citations to
ethics/virtue references (20%), persuasiveness (15%), effective use of figures (15%).
See attached documents on engineering ethics and virtues.

Sports Nutrition Tips and the Nutrition Plan for Athletes

Sports Nutrition Tips and the Nutrition Plan for Athletes

Sometimes someone can ask you what your talent is and at some point when you were growing, you did not have any idea what talent is, right? Then you have grown now and am sure some of you here still don’t know their talents. For the lucky ones who have sports talent, and went to schools which considered co-curricular activities as a great deal, I know they realized what they are good in when it comes to sports. So today am here to discuss about athletes, sports nutrition tips for athletes especially the nutrition plan for athletes.

Many of you might be wondering why it is necessary to have a nutrition plan for athletes and I can assure you that there are numerous reasons behind this aspect. We all need energy to perform our daily activities and tasks and the same case applies to athletes. However, for them, they have to be vigilant on what their diet contains because that is what determines how they work and for those who have taken up athletic as  a career, the foods they eat is what determines their career and how long they will stay in course. That is why the nutrition plan for athletes is a very crucial element in sports.

In order to achieve the nutrition plan for athletes, the meals each individual takes before or after have a great impact on their energy formation, performance and the subsequent trainings. These individuals require a lot of energy in order to optimize their activities hence, it is very common to find them taking more calories in their diet compared to some of us. For instance, the nutrition plan for athletes must contain carbohydrates because as we all know carbohydrate foods are very rich in energy formation and athletes need this energy to avoid instant body fatigues when they are either exercising or performing.

We cannot forget proteins and fats too. I remember when we were young we used to be told how proteins can make you grow, however when I grew up, I realized that proteins have various benefits in our bodies. I will talk about the function of proteins from an athletic point of view, they are a source of energy and in addition to that, proteins help in building up muscles and new tissues. For athletes to achieve their goals they have to train continuously with a lot of resilience because without that commitment and passion, you cannot survive in the sports industry. Additionally proteins are vital in repairing worn out tissues. It is very clear that proteins play a huge role in the nutrition plan for athletes. Take a minute to imagine what if proteins dint exist? You and I know how much these athletes get injuries when they are out there playing or exercising meaning if we didn’t have proteins, injuries will mark the end of their athletic era. Additionally, their muscles will wear out and as a result, they will lack enough strength to help them achieve their sports goals. Therefore we can say proteins will always play a crucial role in the nutrition plan for athletes.

Many of us when we hear about fats, our minds rush to weight gain. However, we have types of fats and the ones recommended for athletes are unsaturated fats. So what do unsaturated fats include? We have examples like nuts, avocadoes, salmon and oils such as olive oil and sunflower oil. These fats helps in forming fatty acids that are not produced directly by our bodies and they are also a major player in the production of bile that breaks other fats in the body. What does this mean? It shows that if a body lacks some fats, it may lead to accumulation of more fats in the body due to lack of bile and I know that if there are extra fats in the body, the end result will be critical health conditions like diabetes, heart attacks and weight gain. No athlete will want to undergo all the above mentioned health issues therefore a little consumption of fats is important in the diet as it also helps in formation of cell membranes and production of more energy.

Sports nutrition also advocates for supplements. The supplements may either be vitamins, minerals or even amino acids supplements. As much as our bodies have different hormones and metabolic processes, sometimes they cannot produce all the required elements in the body, some have to be taken artificially and that is where supplements come in. For instance if we look at minerals, there are a great number of tasks that they help in our bodies for example, transportation of oxygen, balancing the acidic and basic amounts in the blood, maintaining healthy bones and also activation of various enzymes in our bodies. All these processes are crucial and human beings especially the athletes cannot survive without these functions. The most important minerals that take part in these activities are mainly iron and calcium and the bodies don’t produce enough of these at times. That is where supplements come in. Dietary foods with these minerals must be included in the nutrition plan for athletes to ensure their bodies are fit and healthy for the purpose of incredible productivity.

I cannot forget to tell you about the essence of water and other energy drinks in the nutrition plan for athletes. Dehydration is very dangerous and that is why health specialists insist that we must always take a lot of water on a daily basis. Water is essential in all the metabolic process that take place in our bodies. The moment we become dehydrated, that is the point where our health is at risk. Therefore athletes also need water and other energy drinks to keep them hydrated during exercises. Energy drinks help in adding sugar to the body during exercise to avoid extreme fatigue by producing more energy to carry the athletes through the activity.

As much as all the above discussed aspects are important in the nutrition plan for athletes, the most important point here is that they should be taken in the right amounts in order to achieve the goal of keeping the athletes fit and productive.

  1. List two distinct lines of evidence used to support the “spatio-temporal spread” hypothesis in your own words. (max. 2 pts)



  1. How are these two hypotheses different in terms of their predictions? Contrast the predictions of each hypothesis. Explain in 2-4 sentences, using your own words. (max. 2 pts)




  1. Please list and explain one strength and one weakness of each hypothesis in the chart below. A weakness is something about the hypothesis (an assumption, way something is measured, piece of data, combination of data, or absence of data, etc.) that makes it less convincing. A strength is something that makes it more convincing. (max. 4 pts)

Climate-Linked Epidemic    

































  1. If you were Ms. Torres, and you had to briefly describe to your students why the frogs have disappeared in this forest, and what you think is the most likely explanation, what would you say? Write your explanation as if you are talking to high school students. Be sure to synthesize the information available; your explanation should include an informed evaluation of the evidence. Please explain it as clearly and completely as you can in the space provided (~100-150 words). (max. 2 pts)




Finally, read carefully the following information and answer the last two questions.


In a new study, Cheng et al. (2011) recently described a new genotyping technique —a way to discover the genotype of the sample— by which amphibian museum specimens can be tested for the presence of chytrid fungus through a simple swab. This DNA-based technique uses the polymerase chain reaction (PCR)2 to detect the presence of Bd DNA in the skin of specimens, and can be used for specimens collected up to 50 years ago.

  1. Please read carefully and as many times as needed. How would you use this new tool to help understand the causes of enigmatic amphibian declines knowing that many museums have been collecting specimens from Central and South America for decades? Provide a specific example or scenario of where and for what purpose, you could use this technique. (For example, what would you test for and in what populations? What would you expect to find, and what would it mean?). (max. 3 pts)


  1. Please read carefully and as many times as needed. How might new evidence from using PCR on specimens from several decades ago strengthen or reject the hypotheses above? Describe how new evidence could be used to produce data to strengthen each hypothesis, and what data that would be. Explain. (max. 6 pts) —-PCR is a molecular technique used to amplify specific fragments of DNA. If the chytrid fungus is present on a frog specimen, chytrid DNA fragments will be amplified with the PCR.
