It is important to have normal levels of bacteria in our ecosystem. Good levels of bacteria protect the body by preventing other types of bacteria from overgrowing and producing toxins. Good bacteria can also help with breaking down food that the body itself cannot absorb in turn teaching the body to not have an overactive immune system by helping prevent allergies and training immune cells whilst also increase appropriate growth of epithelial cells. It is important to have research and knowledge because without understanding bacteria we can’t tailor antibiotics to target only specific bacteria and medical teams cannot know how to restore healthy levels of bacteria after treatment has passed.

The most fundamental technique for classifying bacteria is gram staining, during this procedure crystal violet stains the bacteria and treated with mordant- a solution that fixes the stain inside the cell. The bacteria is then washed with a clear agent such as alcohol. Gram positive bacteria take up the colour of the gram stain (violet) and cannot be counterstained whereas gram negative will not. This is an important method as it will allow scientists to determine which antibiotics will kill particular bacteria. Although using gram staining to identify bacteria another way is to identify the bacterium though its shape and cell arrangement, the most common shapes of bacteria include rod, cocci (round) and spiral. The bacteria used in the experiment ; Staphylococcus Epidermis is sphere shaped, Escherichia Coli is rod shaped, Micrococcus Luteus is sphere shaped and the Serrates Marsescens is rod shaped making them identifiable by their shapes.

Bacteria is a fast growing organism, it can multiply and cover surfaces in a short amount of time. The way it multiplies is through binary fission, the result is the formation of two bacterial cells that are genetically identical. For

Dramatugy

...Dramaturgy Everyday we play different roles in society. There are different sides that we show to each individual we encounter based on what their roles are in our lives. In this paper, I will discuss the sociological perspective known as dramaturgy. I will describe my front and back stages. My use of impression management will be discussed as well as why we use this form of management. Being social beings on the stage of life, we must play our parts accordingly. Dramaturgy is one social perspective that revolves around role playing. This theory says that we are like actors on a stage and we take on many roles when we interact with others. We constantly change our role (character) when we meet new people. There are two stages associated with dramaturgy and they are the front and back stages. The front stage is the stage where actions are visible to the audience and are part of the performance. Everyday my life is filled with front stages. My office where I work as a Correctional Records Technician serves as one of my front stages. It is there where I assist a multitude of public citizens on a daily basis. My home is another front stage. This is where I take on the role of head of household. The back stage is where performers are present but audience is not, and the performers can step out of character without fear of disrupting the performance. When I get into my car and turn the radio on and hear a song with a nice beat, I start singing and moving to the beat. My car serves...

My Biography

...Road Not Taken asked that I stop to consider every time I moved my jawa-like wizard around its grid-based maps. On one level I stared at the screen for about five minutes, contemplating every possible route to get the last child I needed to rescue to beat the area while avoiding a malicious black spirit that would drain about a fourth of my current health. But if I made too many useless moves here, I could end up without enough left to finish the next level. I eventually got to the child, but not without taking a spirit to the face - acceptable losses. That risk-reward balance is a clever hook at first, but it too quickly became less exciting as I played. Learning to match the varied animals, monsters, spirits, and other objects scattered across Road’s randomized levels in the fewest movements possible was, at first, unforgiving (leading to situations like my five-minute stumper). Every new object was a surprise, and some are as likely to end a good run on the spot as they are to help you out. But that’s to be expected from a Roguelike, where the first few sessions are more about learning the ins and outs than anything else. Most Roguelikes remove all your progress on death, making your knowledge of what to expect next time around the most palpable form of progress; here that knowledge is solidified in the form of a persistent and indispensable notebook that fills out as you uncover new objects and combinations. Being able to look up what each piece I encountered could turn...

A Conceptual Model of Corporate

...have been miserable failures. Reidenbach and Robin’s notion of corporate moral development is based on the American psychologist Lawrence Kohlberg’s conception of individual moral development (see Unit A3). Kohlberg has described moral development as moving through three main levels. Each level is divided into two stages, so there are six stages in all. Some individuals progress through all the stages, while others get “stuck” at the lower stages. Pre-conventional level (stages 1 and 2). At stage 1, the infant is initially motivated purely externally by fear of punishment, such as a spanking, and at stage 2 by a desire for rewards, such as a piece of candy. Conventional level (stages 3 and 4). Stage 3 is the “good-boy/nice-girl morality,” in which children seek their parents’ or peers’ approval. After this, an individual may move to stage 4, the “law and order stage,” in which great value is placed on following social rules. At this stage people have started to move beyond merely an egoistic motivation to one in which there is real concern for meeting standards for non-selfish reasons. Kohlberg believed that most adults remain at this stage. Post-conventional, autonomous, or principles level (stages 5 and 6). Here, one accepts moral rules not just because they are part of one’s society but because one knows that the rules are right. In stage 5, individuals see morality as a kind of contract between individuals that grounds individual rights, a position which is very...

Catastrophe and Crisis

...sometimes ago. It was just a short news article in one of the local dailies. The story keeps on ringing in my mind up to today. I feel that the whole nation should stand and honor this woman for her courageous actions she portrayed on this fateful day. It happened that in the year 2007 in the city of Orina in India, a town that had over 100,000 people. It was raining heavily, and life was almost coming to a standstill. Everyone in the area woke up in shock after finding pools of water moving at alarming speed sweeping everything it came across. It was around 8 in the morning. Before even people realized what was happening, the water level started rising, and there was no accessible route to escape. People quickly rushed out of their houses and water was unfortunately found themselves stranded as the water level continued to rise above the level of their waists. At this moment, the rain was still slowly falling, and everything became a menace. After about an hour, the town was full of water and people were trying helplessly to come out of the water. Water was gradually rising, and there was nothing else visible but water. It was a moment of darkness as people started drowning one after the other. The aged people and children were the most affected. Everyone was screaming to save his or her own life. There was neither gender nor tribe; the language was the same; Save a life at whatever cost. One young lady rose up from nowhere, amidst dead bodies floating on water. Death was inevitable...

In aggregate planning various mathematical techniques can be used to obtain feasible schedules. With planning methods is to optimize the use of resources avoiding sudden changes in production and at the same time reduce the total cost planning. The importance of aggregate planning in the process of managing an organization is to establish plans for short and medium term to meet the requirements of the production forecast when the capacity from the standpoint of plant or equipment is relatively fixed. INTRODUCTION In this paper I’m going to talk about Aggregate Planning Strategies. The aggregate planning serves as a link between the decisions about the facilities and programming. The decision of the aggregate planning establishes production levels overall medium term, which is why it is necessary that the company these processes is implemented, making decisions and policies that relate to overtime, hiring, layoffs, outsourcing and levels inventory.

Simulation Reflection Paper

...given an opportunity to think critically about how to approach to influence different managers and workers with different characteristics. By running the simulation twice, it allowed us to find out what actions have worked and what did not during the first run, and then second run allowed us to apply what we learned to complete the second simulation in a much more efficient and timely manner. There are three stages in the simulation, including mobilization, movement, and sustain phases. The simulation begins in the mobilization phase, and in this phase it was important to get everyone aware of the new change we wish to initiate in the company. The key factor in the beginning was to introduce the new project to each person on a personal level, using personal interviews, skill building, and getting consultant’s support. All of these involve personal contact and were effective in making people both aware and interested to the change. The second stage was movement phase, and the key factors that lead to success in this stages was maintaining high credibility. We could gain credibility through getting consultant’s support and getting CEO’s public support. As majority individuals got into interest and trial stages we were able to use town hall meetings and walk the talk, which attracted more workers to be in interest and trial stages. Again, maintaining high credibility was important throughout the stages because low credibility meant low chance with people would buy in to the initiative...

Hypothesis

...It is an often debated topic when discussing the comparison of stress levels of women compared to the stress levels of men. There are different causes of stress as well as different methods of relieving stress. On average, women feel as though they have more stress than men and handle stress better than men. Many people experience different forms of stress. Be it personal, emotional, physical or work-related. How to handle these kinds of stress is essential to having a balanced life. We all get emotional occasionally or lose our temper once in a while. But if you are out of balance in either one of these areas, it is very important to get back in balance if you want your day or life to go right. If your feelings get hurt because someone looks at you the wrong way or because friends, family and even co-workers forget your birthday, some spend more time with God praying and asking for the hurt to be lifted off of you. You will be built up in your spirit and better able to overlook the offenses of others and forgive them. Forgiving is an excellent stress reliever. Releasing all of that tension and calming your spirit. Quite of few people relieve their stress by praying. Giving your issues, concerns and worries to God is the best thing you can do for yourself. Another form of stress relieving is listening to music. Music, they say, can soothe the savage beast and we all have a savage beast in us some times. It can be jazz, instrumental, classical or gospel just to name...

...Software Evaluation Science Software Evaluation Lindsey Young Grand Canyon University TEC 537 Strgs &Intrg Prod. Software August 18, 2010 Science Software Evaluation Educational software is an important component integrated into most current curriculums. However, as an educational facilitator it is important to evaluate the software being incorporated and utilized by the students. Because instructional time is limited, it is imperative that each educational piece be relevant to the students learning and the overall educational goal. A great way to rate, or evaluate, is through the careful creation of a rubric. A rubric not only organizes the key elements, but it also breaks down these key elements and arranges them by relevance. The attached rubric allows the rater to evaluate technical and educational aspects of educational software. It checks the significance of the software’s content, the accuracy of the content, active or inactive links embedded in the software, graphics, layout, material that students are expected to know to be able to utilize the software effectively, age and grade appropriateness, and curriculum connections. Using the rubric, one can evaluate the overall effectiveness of two online educational software tools. For example, Sheppard Software was created by Brad Sheppard, to provide an educational tool for students in all subjects. Using the rubric, lets evaluate Sheppard’s Chemistry games on the periodic table. There...

Summary: Microbe's Effect On Humans

...Microbe’s Effect on Humans Research at McMaster University has linked the bacteria found in a person’s gut to depression and anxiety (Gut). People that have irritable bowel syndrome or late onset autism had atypical gut bacteria. Stephen Collins, Associate Dean of Research and professor at Michael G. DeGroote School of Medicine, and Premysl Bercik, an assistant professor, conducted the research on healthy adult mice and mice that showed aggressive behavior at Farncombe Family Digestive Health Research Institute (Gut). Healthy mice were given antibiotics which transformed the gut bacteria content. The mice were then linked to anxious behavior. However, when the mice were taken off the antibiotics, their bacterial content returned to normal, as did their behaviors (Gut). Collins and Bercik also found that when normal, healthy mice were colonized with aggressive and active behavior mice’s bacteria, the healthy mice...

Aeromonas Hydrophila

...amputation, and even death. Aeromonas Hydrophila: The Improbable Culprit As the summer months begin to elevate the mercury level, nature’s creeks and streams provide cooling entertainment from the elements. People have long used these waterways for recreation activities, such as fishing, walking, swimming, and canoeing; unsuspecting of the dangers. Most bacteria are harmless, but certain types can cause complications and disease. The flesh eating bacteria Aeromonas Hydrophila, can create unthinkable devastation through minor cuts and scratches; causing sickness, amputation, and even death. The world has thousands of micro-living organisms called bacteria, these unicellular microorganisms have cell walls, but no structured nucleus, some of these microorganisms can cause disease (Hogan, 2005). Thousands of bacteria inhibit our environment every day, many of them unidentified but not all of them are unhealthy. Bacterial cells consist of shapes; spherical, rodlike, spiral, helical, and comm-shaped (Lerner, 2005). The unique shapes of bacteria create classifications used for identification. Gram staining is another tool used for identification; originated by a German bacteriologist named Robert Koch (1843-1910). The process of Gram staining differentiates bacterial species into gram-positive or gram-negative groups. (Bacteria,2007). Classified as a rod-shaped, gram-negative bacterium, Aeromonas Hydrophila...

Aneorobic Bioremediation

...in-situ by activities of microbes is a safer and more economical technique than the physicochemical one and is being developed for practical application. This paper describes that anaerobic bioremediation which cleans up soil and groundwater contaminated by chloroethene such as TCE in-situ by anaerobic bacteria. 1. Degradative mechanism Anaerobic bioremediation is a remediation technique which injects organics, which become electron donors, together with nutrient salts such as nitrogen and phosphorus into groundwater and degrades contaminants by anaerobic bacteria. It is known that PCE and TCE are dechlorinated reductively by anaerobic bacteria and degraded into dichloroethylene (DCE), vinyl chloride (VC), ethylene and likewise, ethane (Fig. 1). Various types of anaerobic bacteria can degrade not only PCE and TCE but also cis-1,2-DCE. Its speed of degradation is relatively fast. On the other hand, by using cis-1,2- DCE and VC as an electron acceptor, Dehalococcoides bacteria is the only anaerobic bacteria which can completely degrade ethylene and ethane. It has been reported domestically and internationally that, in contaminated sites where Dehalococcoides bacteria is not present, TCE can only be transformed into cis-1,2-DCE but not dechlorinated completely because degradation stops even if a nutritional...

Relationship Between Tetanus And Climate Change

...Tetanus and Climate Change Tetanus is a serious infection that affects the brain and nervous system and is caused by the bacteria Clostridium tetani. If the bacteria is deposited in a wound, it releases a toxin that enters the bloodstream and interferes with the nerves that control muscle movement. Some symptoms include lockjaw, painful muscle spasms, and rapid heart beat. It can be found anywhere, but mostly in soil, dust and manure. The bacteria is also anaerobic which means it lives in the absence of oxygen. Taylor (2003) stated that the distribution of tetanus follows the areas of moist, warm climate and fertile soil and the highest rates occur particularly in countries near the equator. During the 20th century, the Earth’s average temperature rose one degree Fahrenheit to its highest level in the past four centuries which is believed to be the fastest rise in a thousand years (The Nature Conservancy, n.d.)....
