Temperatures have a great effect on microorganisms. In the most general sense, bacteria can grow at any temperature between freezing point of water (32°C) and the point where proteins coagulate. Between these two high and low temperatures, each bacteria type has an optimum growth temperature. An optimal growth temperature is the point at which an organism grows best, with optimal cell metabolism. If temperatures creep past the maximum, bacteria are killed. If the temperature drops below the…

A drive or motivator is a force or reason that compels one to do something. Thus, for a motivator to be effective there must be a cause and effect chain reaction that will impact the decision taken. Being a nurse, I always have to be on my feet and help anyone who enters the hospital, as their lives rest on us. A main motivator that impacts my performance at work is the willingness to have empathy and compassion towards the patients in a way with the goal of restoring or improving their health…

During the four week fitness log I was able to achieve most of my goals. The first goal I achieved was being able to lift 115 lbs on the leg extension. I accomplished this goal within the first two weeks. By the end of week three, I slowly made my way to 10 reps of 115 lbs constantly. I believe that doing squats, wall-sit, and other leg workouts increased my ability to achieve the goal. I was unable to achieve my second goal because I set my standards too high. I was only able to run 3-6 minutes…

From what I have seen from my nutrient intake report, I definitely need to make major improvements in some areas of my diet. For starters, I missed the minimum calorie requirement for one week by over two-hundred and fifty calories. This is a major aspect of my diet that I want to change, because if I don’t feed my body with calories, vitamins, and minerals, I will not be able to increase my performance on the football field by any significant amount. If I want to increase my performance on the…

Dear Members of the Review Committee: I am writing this letter on behalf of Neil Chappell, MD, in order to convey my strong support of his grant proposal entitled, “Hyperandrogenemia alters ovarian mitochondrial function and subsequent oogenesis and embryo development in a PCOS mouse model.” As his mentor and principal investigator, I am committed to the development of his career, and will assist him in any way I can to ensure his success in all professional endeavors. To date, Dr. Chappell has…

Energy performance of the original house is not terribly bad but not satisfied, either. It wastes a huge amount of energy in cooling the living area. Strategies of achieving better passive heating and cooling will be illustrated as following. Reducing cooling energy consumption will be emphasized in designing the new house. The original orientation (315 degrees with living room faces south-west) resulted in excessive heat gain during summer, especially in the afternoon, and insufficient heat…

Chasing Wakes Summertime is one of the most dreaded seasons of the year for those who live in the desert. It is a time for the rattlesnakes, lizards, and tortoises to emerge. While these creatures flourish in the blistering temperature of 120 degrees, humans quickly deteriorate. This kind of climate creates scaly, dry skin making a person feel like their own skin is as rough as one of those reptiles. I have found being on a Sea Doo, also known as a water motorcycle, at the Colorado River is one…

Issues Analysis Are sports drinks a better a better substitution for water when playing sport? Since the introduction of sports drinks in 1965, they have been a big part of professional and non-professional sports since then. According to Forbes, Gatorade is currently the most popular sports drink in the world with sales generating over $1 billion per year and this just goes to show how huge the sports drink industry really is. The main issue with sports drinks is that people are choosing to…

If the temperature of the water is 38 degrees c, then the growth of the plant will increase. This science fair project is to test whether or not the temperature of the water you water the plant with will affect the growth of the plant. This project is interesting because the way plants grow is an interesting study. In this project i hope to achieve an answer on whether or not a plant’s temperature of water should be a certain temperature to help the growth of the plant. The radish (Raphanus…

Introduction Heat exhaustion is a condition caused by exposure to extreme heat. Heat exhaustion means that your body is too hot. Your body cools itself by sweating. When your body cannot cool down, you could develop heat exhaustion. Untreated heat exhaustion could lead to heat stroke. Heat stroke can be deadly. Elderly adults have a greater risk for heat exhaustion than younger adults. Other adults who may be at higher risk are those who are overweight, have high blood pressure, or have heart…
