...In order for this experiment to be successful one must follow a certain procedure must be followed. This procedure begins by gathering the following materials, four, seven gram packets of Fleischmann's baker's yeast, for petri dishes, four beakers, three colored light bulbs (red, white, and blue), ¼ a cup of warm water at 100 degrees Fahrenheit (per packet of yeast), 1 teaspoon (tsp) of sugar per yeast sample, a stopwatch, a camera, and a ruler in centimeters. After gathering these materials one must take all the colored light bulbs and screw them into a light fixture. This light fixture must be kept in a dark location, such as the closets used in the experiment, to make sure the yeast sample has no contact with any other light. Then the...

...can also go without by using fermentation or anaerobic respiration when it is not available (Betsy & Keogh,2005). The microorganisms being cultured in our first task (Lactobacillus acidophilus and Staphylococcus epidermidis) are obligate aerobes. Microorganisms can grow in a variety of conditions with temperature being one of those variables, but the types we frequently encounter in our environment thrive in fairly warm temperatures. Both Lactobacillus acidophilus and Staphylococcus epidermidis are examples of these, which are referred to as mesophiles. Extreme temperatures (as in deep freezing or auotoclaves for example) are effective in destroying microorganisms due to their inability to thrive outside of more moderate temperatures). Growth of these two organisms would be optimized by remaining between 25 and 40 degrees celsius (Betsy & Keogh, 2005). The higher end of this range should increase the rate of growth as it causes a higher rate of metabolism, which is why our experiments suggest using an incubation box if our house is not overly warm. There are many ways we actually benefit from enhancing the growth of microorganisms and on the flip side are the ways we depend greatly upon eliminating as much growth as...

... This paper will again use the process identified in week one to complete a Statistical Process Control that can be used to verify my standard process is operating in a way that allows me to complete all of the tasks and affords me additional time. This paper will also outline the control limits of my morning process, the effects of any seasonal factors, and the confidence intervals involved. Statistical Process Control Data was recorded for a period of two weeks on how long it took me to complete my morning routine and get my kids off to school. I tracked the minutes it took me to complete each step of my morning routine and used the totals from each day to calculate the mean. On average, the time it took me from the time I woke up to the time the kids were delivered to school was 150 minutes. The standard deviation is 10.54 minutes. [pic] Control Limits It would be unreasonable for me to expect that I could complete this process – each day – with no variance in the completion time. This is why I created the control limits to serve as the minimum and maximum expected standard. The upper and lower control intervals...

...There is definitely a variety of different transfusion reactions a patient can obtain and can pertain to a wide range of causes. Some of which can be caused by a warm antibody. Warm Autoimmune hemolytic anemia (WAIHA) which can be idiopathic and seen more often than a cold antibody, is actually one of the most common autoimmune hemolytic transactions occurred; often they are IgG antibodies and occasionally 1gM or IgA. Therefore, it is critical to ensure every patient's blood work is verified through out all blood test: ABO/D, Antibody Screen, Antibody Panel and Crossmatch. A warm antibody simply consists of an antibody that can be detected at 37° C or above Celsius. Warm antibodies that have been identified in the past can be any of the following:...

...The Diels-Alder Reaction of Anthracene with Maleic Anhydride The Diels-Alder reaction is a member of a class of reactions called cycloadditions. The reaction involves three π bonds, two from the diene and one from the dienophile in a concerted reaction to form a six-membered ring. Since the reaction involves four π electrons in the diene and two π electrons from the dienophile, it is sometimes referred to as a 4 + 2 cycloaddition. Normal Diels-Alder reactions are favored by electron donating groups on the diene and electron withdrawing groups on the dienophile. The diene must be capable of achieving an s-cis conformation to generate the cis double bond in the cyclohexene product. Acyclic dienes may rotate around a single bond, but dienes locked in the s-trans conformation do not react. [pic] The purpose of this experiment is to form 9,10-dihydroanthracene-9,10-α,β-succinic anhydride by way of a Diels Alder reaction between anthracene and maleic anhydride, as shown in the reaction below. Anthracene acts as the diene and maleic anhydride functions as the dienophile. Xylene (dimethylbenzene) is used as a high boiling temperature solvent so that the reaction will proceed quickly. Melting temperature analysis will be used to characterize the product. Anthracene Maleic anhydride 9,10-dihydroanthracene- ...

...biggest loser is that you do not have to be on the show to achieve weight loss. I am a big fan of the TV show, and I noticed that the diet consists of our everyday food groups and that the exercise program can be simple. If the program is consistently followed, anyone is capable of becoming a “big loser.” The first rule that is needed to in becoming the biggest loser from home is the diet plan. Research shows that in this diet eating three meals a day and having a snack in between two of the meals can enhance weight loss. A sample of a daily meal plan: Breakfast: ½ serving protein, 1 serving whole grain, 1 serving of fruit Snack: ½ protein, 1 fruit Lunch: 1 protein, ½ whole grain, 2 vegetables Snack: ½ protein, 1 fruit Diggs 2 Dinner: ½ protein, ½ whole grain, 2 vegetables Notice there is no specific food required which means there is no extra fee for a meal plan. This sample can be found on the Web MD website. A dieter can basically eat anything as long as it is not alive. Another incentive for using the biggest loser program is that it is very inexpensive. Chef Cheryl Forberg is the dietician who established the diet used with the biggest loser plan. Forberg states that in this diet the emphasis is on the quality of the calories. A person can meet his or her nutritional needs [and] enjoy more natural, healthy whole foods and lean proteins with her plan. This plan also helps curb...

...You are given a sputum sample from a patient that may be infected with a bacterium from one of the following genera: Bacillus, Escherichia, or Mycoplasma. In a Microsoft Word document, describe the important anatomical differences among these three genera (i.e., those features that could be used to differentiate among them) and the staining protocols you would use to identify which genera is causing the patient’s infection. When discussing each staining protocol, it is important not only to mention the steps involved, but also how each step and each protocol would identify or eliminate each of these genera as a suspect. You may refer to other scientific resources, but they should be in addition to and not in place of the Module 2 resources. Bacillus: Rod Shaped Bacteria, plural bacilli, Divide only across their short axis, most appear in single rods. Diplocacilli appear in pairs after divison, and streptobacilli occur in chains. Some bacilli look like straws, others are tapered and look like cigars and some are oval and look similar to cocci so they are called coccobacilli. Genera Bacillus contains bacteria such as Bacillus anthracis the bacteria that causes anthrax. Bacillus cells often form long, twisted chains of cells. Gram POSITIVE, can be aerobic or anaerobic.

Apply a wide (< 100mm/4inch >) elastic crepe bandage over the bite site then continue this bandage evenly over the entire limb to the armpit or groin (It should be as tight as one would bandage a freshly sprained wrist or ankle) then any left-over bandage should be continued down the limb. A 2nd, 3rd; and possibly 4th bandage should be applied over the first (pending whether bite is on arm or leg) starting over the fingers or toes. 3. Immobilize the bitten limb with a splint, stick, or rolled up newspaper or cardboard, bandaged or tied to the limb, or use a St. John's sling or air splint applied to limb. All joints of bitten limb need to be totally immobilized. If bandaging is not available, tear towels, sheets, clothes, petticoats, etc; into strips, even pantyhose may be used.

...your true self]. Why a Self Portrait? A self-portrait allows you to see your beauty, understand your shadows, and express your feelings and reflections. It is a powerful tool that can help you to understand yourself on a deeper level, ultimately promoting inner peace, change, and personal growth. Where do I Start – and End? Obviously, attempting to understand yourself is a process that necessitates an introspective journey. • Begin by experimenting with some of the warm up techniques that are listed on the back of this page. These techniques should get you thinking in a reflective direction. • Once you have completed some of the warm up activities, log on to Moodle, and review the “It’s All About You” PowerPoint posted there. It contains examples of self–portraits from various professional artists (along with, in many cases, their statements of intent); some instructional tips on art techniques, terms, and materials you might use to create your own work; and sample projects from previous years’ philosophy students . • Draft your ideas, considering both the “soul secret” on which you plan to focus and the materials you might use in your execution; gather your materials; and create your portrait. Make sure to leave yourself enough time for experimentation and error – especially if you are delving into an area (of artistic execution) that is new to you. • Finally, write a brief statement of intent (approximately one typewritten page) in which you...

...proteins that speed up the rate of reactions that would otherwise happen more slowly. The enzyme is not altered by the reaction. You have hundreds of different enzymes in each of your cells. Each of these enzymes is responsible for one particular reaction that occurs in the cell. In this lab, you will study an enzyme that is found in the cells of many living tissues. The name of the enzyme is catalase (KAT-uh-LAYSS); it speeds up a reaction which breaks down hydrogen peroxide, a toxic chemical, into 2 harmless substances--water and oxygen. The reaction is: 2 H2O2 ----> 2 H2O + O2 This reaction is important to cells because hydrogen peroxide (H2O2) is produced as a byproduct of many normal cellular reactions. If the cells did not break down the hydrogen peroxide, they would be poisoned and die. In this lab, you will study the catalase found in liver cells. You will be using chicken or beef liver. It might seem strange to use dead cells to study the function of enzymes. This is possible because when a cell dies, the enzymes remain intact and active for several weeks, as long as the tissue is kept refrigerated.

Earth's Bounty goal is to attract a younger audience from the ages of 16-24, research shows that this age demographic makes up the largest vegetarian/vegan population. Another target audience Earth's Bounty is tying to market to are people that are looking for a healthier food alternative when deciding to dine out because vegetarian food is known for being healthily. By being located in suburban area’s it’ll make eating healthier an option over the abundant amount of fast food restaurants. Both vegans and vegetarians need more local restaurants to go to so they don’t have to worry about food cross contamination. Knowing that vegetarian food is healthier then most non vegetarian dishes, the market for healthy eaters would likely help the success of this brand. Few restaurants offer vegetarian meals but in my personal experience their is a huge market that hasn’t been fully exploited. With Earth’s Bounty being urban, warm and inviting with the use of toned down greens and warm browns, customers will feel welcoming and come in and try food maybe a little out of there comfort zone. A competitor Earth's Bounty is up against is Nuba Restaurant on 207B West Hastings.

...even the slenderest mistake will cause an outbreak and may eventually lead to an epidemic. It’s crucial that medical mistakes don’t occur no matter the scenario, especially in a Level 4 ‘hot zone,’ a highly dangerous area. In The Hot Zone: A Terrifying True Story, by Richard Preston, the author diversifies the different medical errors that contributes to the spread of deadly viruses through demonstrating the usage of unsanitary needles and improper handling of equipment. Without a doubt, the author assuredly discloses that the usage of unsanitary needles is certainly one of the many forms of errors that induces the spread of diseases. To start it off, Richard Preston states, “The nuns and staff occasionally rinsed the needles in a pan of warm water after an injection, but more often they proceeded from shot to shot without rinsing the needle...mixing blood with blood” (Preston, 63). In this peculiar scene, in Yambuku Hospital, located in the Congo, Belgian nuns are giving out medical injections to people who have the fear that they could be infected or those whom already have Ebola. Through using improperly sterilized needles, Ebola and other diseases have a...
