The Environmental Performance Of Canadian Oil Sands Introduction Oil sands refer to loose sand deposits containing highly viscous petroleum known as bitumen. Oil sands are constituted of a mixture of sand, clay, water and bitumen oil, which are situated in the Northeastern Alberta in Canada, which include Athabasca, Cold Lake and Peace River. The oil sand deposits in Canada are the largest in the world, contributing to over 10% of the world’s oil reserves. (Berkowitz &Speight,1975). Conventional crude oil, on the other hand, refers to a liquid petroleum that is pumped from underground. It varies widely in terms of sulfur content, viscosity and density. It is either classified as light, medium or heavy, which is the oils relative density based on API gravity. While crude oil can be pumped from the deposits underground as it flows, oil sand is too thick and doesn’t flow; hence it cannot be pumped from the ground(Berkowitz &Speight,1975). Instead, it is mined through the injection of Steam into the well, which heats it first. Several methods are used in the extraction of oil sands. Examples…

Factors Affecting Time to Hemolysis in Mammalian Erythrocytes Abstract Osmosis and diffusion have a wide range of applications and importance to both plants and animals. In plants, osmosis and diffusion applications include transportation of nutrients and water and carbon dioxide and oxygen exchange. Some of its applications in animals include use in kidney dialysis. Osmosis and diffusion are also applied in salt extraction. Osmosis and diffusion being an essential aspect in life, an experiment using mammalian erythrocytes was conducted to investigate the different factors affecting the rate of both Osmosis and diffusion. Some of the biological processes are supported by osmosis and diffusion. With the wide range of applications in our day to day lives, it is essential to understand how osmosis and diffusion work and the factors that may affect it. In this light, an experiment was conducted to determine the influence of molecular size and polarity on time to hemolysis in mammalian red blood cells. Data were collected during this experiment and tabulated. A descriptive statistical analysis was then done for data analysis. A significant difference was obtained…
The acidity of the Pacific Ocean and Dungeness Crab Impact Environmental changes around the world are having detrimental effects on the environment, both terrestrial and seas environment. Developing approaches to help control these adverse outcomes present a more diverse focus on environmentally friendly techniques. Pacific ocean has been influenced significantly by environmental changes leading to unique adaptation. The level of acidity in the pacific ocean has been increasing significantly (Marshall et al., 2017). The high-level acidification is dissolving the shells of Dungeness crabs. The lower PH of the pacific ocean is having a more considerable influence on the young Dungeness crab shells, which are corroding. He increasing acid levels is caused by the rising levels of carbon dioxide. This can be explained based on the fact that the oceans absorb higher levels of carbon dioxide, which is being released into the atmosphere from different sources. Global warming is a serious environmental concern in recent years, primarily due to the significant emission of greenhouse gases that are disadvantageous to the positive ecological focus. Fossil fuel utilization has been a substantial cause…
book Twelve steps Alcoholics anonymous is an arrangement committed to helping its members live a sober life as well as helping alcoholics in attaining sobriety. The name of the meeting was Friday night as Bill sees it, and it was located at the Torrance-Lomita Alano club on 1645 Arlinghton Aven, Torrance, CA The gathering took place on a Friday at 7:30pm and is held every Friday. The rationality behind picking this location was because it was near my house. When I got into the room I was expecting a meeting that resembled those on the movies, where chairs are set in a round shape and no other furniture’. In this meeting there were plenty of chairs and space. Members sat in a way they were able to see each other. I was nervous because I did not know how the reception will be like. My anxiety left the moment I realized that people are dealing with difficult situations in their lives. It takes bravery to attend these meetings and decide to change. The audience varied in age, ethnicity and gender.…
A Future Really Big Telescope The technological change and evolution, especially in astronomy, has caused or resulted in more discoveries that no human thought would be possible decades ago. In today’s world, due to technological advancement, humans can tour and explore the universe periodically, which can be done through flying to space or use of modern, powerful telescopes. Astronomy has advanced and improved with time, and it has resulted in more discoveries of what is in space and with that people nowadays have a better understanding of the universe and how it works. The evolution of telescopes have come a long way from the simple gadgets that were invented in the old days to the modern high powered telescope we have today, and the evolution is still happening. The first telescope was built by George Ellery Hale also known as the telescope builder. Hale initiated projects that resulted in the development of the first-ever telescopes used to observe space. The telescopes made by Hale were simple gadgets, but with time, he continued improving the size of his telescopes (Fraknoi, 2017). …
Project milestones and Project timeline Project milestones The first point to measure the success of the project is obtaining the operation license. The idea must get approval from the state laws regarding waste management and business operation. Other documentation is the contract with the garbage collectors to obtain electronic wastes. The second milestone would be getting the required funding. The project must have operation premises, materials, and the capacity to hire skilled labor. The proposal is essential in convincing the investors to take advantage of the opportunity. The final milestone would be setting up the facility and starting the recycling work. Project timeline The proposal preparation should be complete before summer. After that, the members will spend the summer holiday getting the legal documentation and approvals. All the contracts with the suppliers shall be signed during the holiday. Once the team receives support, the members will ensure all assembly works are complete by the end of fall. The project must have the required staff and stock the needed materials. The operations should be ready to start in January. The group…
nuclear medicine and the advancements that it has made since its first use Medical imaging is used to create a visual representation of the internal parts of a body, critical for therapeutic interventions and clinical analysis. Nuclear Medicine is a techniques that uses radioisotopes and radiopharmaceuticals for research, diagnosis, and treatment. By use of radioactive materials, doctors can detect and determine the level of severity in diseases like; cancer, neurological disorders, and heart problems. This method presents a painless and a less expansive technique for making the diagnosis in the internal components of a body. Gamma rays are emitted from radioactive chemical tracers, and these rays give the diagnostic information of a patient’s anatomy. Approximately 5 in every ten people in the developed nations have benefitted from this technique. This method functions by recording more body radiations as compared to the emissions of the external sources. There are different nuclear medicine scans in this method and the primary emphasis is not the imaging modality (Chandra & Rahmim, 2017). The two commonly used techniques in nuclear medicine are; Positron emission and…
Agricultural Anthropology 600 words tops. intro, body, and conclusion. there must be three body paragraphs: one about ″allowed″ product, one about ″not allowed product″, and comparison. Instructions: In this activity you will evaluate the scientific basis for these claims about human diet. First, read through a recent discussion of this fad diet by National Geographic: https://www.nationalgeographic.com/people-and-culture/food/the-plate/ 2014/04/22/prehistoric-dining-the-real-paleo-diet/ After reading this discussion, select one foodstuff that proponents of the Paleo Diet assert is “allowed” by the diet (and thus is something humans are “evolved” to eat), and select a foodstuff that is “not allowed” by the diet (and thus is something humans are NOT “evolved” to eat). A list of allowed and not allowed foods is provided below. Research the history of domestication and human use of these two foodstuffs to identify the following: 1. Where and by whom (i.e., what culture or society) were these first domesticated? 2. When were these first domesticated? 3. [unique_solution]What is the wild (nondomesticated) species from which the modern cultivar derives? 4. What are the ways in which the modern cultivars differ from the nondomesticated versions?…
Admission Essay for Medicine Studies Medicine is not only about treating conditions using existing treatment methods, but it also entails research into modern and new methods of combating a growing number of healthcare challenges. In the process of researching the causes and possible cures for some of the most chronic diseases affecting humanity today, medical scholars and scientist have narrowed down the unitary cell as the key to solving these healthcare challenges. Certain virulent diseases such as plaques and HIV, as well as cancer, diabetes, degenerative diseases such as ALS, Alzheimers and Parkinson’s continue to be evasive in terms of modern methods of treatment (Jackson and Chester 262). Unfortunately, most of these diseases are terminal, more so when diagnosed at a relatively advanced stage. However, gene therapy promises to reverse this status quo if recent scientific breakthroughs made at the MIT are anything to go by. I have always wanted to study medicine since it became clear that certain diseases could not be cured. It did not make much sense to me why doctors would not be able to treat…
