Introduction In all areas of biology, it is easy to see that structure is related to function. This statement holds true in microbiology as well, the study of microorganisms, including bacteria. One characterizing feature of bacteria is the cell wall, which can generally (although not in all situations) be categorized into one of two categories: either Gram positive or Gram negative. Gram positive bacteria’s cell walls are composed of a large peptidoglycan layer (up to 90% of their cell wall). Within this large peptidoglycan layer, one can find techoic acids, which contribute to the maintenance of cell wall structure, and lipotechoic acids, which attach to membrane lipids. Gram positive bacteria that act as pathogens can also potentially release exotoxins, which can have very dangerous effects on humans. Gram negative bacteria, on the other hand, have a very small layer of peptidoglycan in their cell wall, which is surrounded by an outer membrane. Within the outer membrane, one can find th e lipopolysaccharide layer, which is one of the most distinguishing factors of Gram-negative bacteria. It is important to note that Gram negative bacteria fail to possess techoicShow MoreRelatedHow to Write a Lab Report in Microbiology1637 Words   |  7 PagesWRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL Unknown reports in microbiology are written in scientific format.

Thanksgiving Speech Example

Thanksgiving speech example is a sample of either a formal or informal address delivered to a particular audience. The speech may dwell upon the background and traditions of the holiday. The Thanksgiving speech example can be used by a family member during the celebration, or by a representative of some official event. Importantly, the speaker may use not only speech sounds but also gesture in order to convey the information. â€Å"Good afternoon everyone! Today, I would like to say a couple of words in honor of one of the most respected holidays in the United States of America. Today, we gathered together all our dearest friends and relatives in order to give thanks the same way as our arch fathers did the long time ago. It is not a secret that Thanksgiving is one of my favorite holidays as long as it is one of those rare days when the whole family and the closest friends are together in one place ready to share the warm mood, excellent wine, and the tastiest dinner with each other. This is the day which seems to be a nice break in between the working routine. It happens so that we spend almost all the time without noticing some minor changes in the world in general, and also in the lives of our neighbors. It is a big pleasure for me to see each of you today here. Despite the fact that the weather is rather unfavorable, you managed to get here. That is, perhaps, the first thing for which I am really grateful. With all my heart, I would like to thank you for such a nice beginning of the evening. I would also like to thank you for all those people who were directly involved in the process of preparation. My dear friends, without your help the holiday would not have been so nice and organized. That is a kind of thing which is an integral part of the true American spirit a team spirit. The real Americans know the price of the unity. For that reason, let us be as organized, full of energy, and helpful as we were today. In our family, Thanksgiving is an appreciated holiday since the early years of our children. Taking this into consideration, my wife and I expect not only our children but our grandchildren to continue the tradition and supplement it with the new elements of celebration as well as increase the number of those who will come to our place in order to share a good mood and original dishes with others. Thanksgiving is like Christmas in autumn the holiday has some warmth in it and in the way it attracts good people. I will not encroach upon your time anymore as the dinner will get cool soon. I will just say thanks for being that nice to all people who came, joined us here, and made the celebration possible. Enjoy your meal, friends. Happy Thanksgiving!†

Twelfth Night Theme Essay - Love as the Cause of Suffering

Love as the Cause of Suffering In William Shakespeare’s play Twelfth Night, love as the cause of suffering is one of the most prominent theme of the story. Even though this play ends in love and wedded bliss, Shakespeare also shows us that love can also cause pain. The characters often view love as a curse, something that is thrust upon you and you cannot easily or willing escape. Examples include Malvolio’s love for Olivia, the love triangle between Olivia, Duke Orsino, and Viola as Cesario, and Antonio’s crush on Sebastian. There are countless occasions where unrequited love for another results in heartbreak and sorrow. Malvolio is a social climber, he feels that if Olivia would love him his status would be higher. But because of†¦show more content†¦It stands as Olivia loves Cesario/Viola, who loves Duke Orsino who loves Olivia. Each character suffers in sorrow as they cannot have who they desire, because of status, gender or love for another. Antonio rescues Sebastian after the shipwreck that separated him from his twin, Viola. Antonio immediately takes a liking to Sebastian and helps get back on his feet. Sebastian heads to Duke Orsino’s court to look for work, Antonio offers to help but Sebastian has to decline as Antonio is a wanted man and accompanying him on his journey would put him at risk. â€Å"But, come what may, I do adore thee so, / the danger shall seem sport, and I will go.† (2.1.43-44) Antonio follows him anyways and ends up encountering Viola dressed as Cesario in the middle of a fight with Sir Andrew. Because Antonio thinks Cesario is Sebastian, he steps in to defend him, out of his love. Viola is confused because she’s never met Antonio before. But, Sir Toby and Sir Andrew recognize him as the wanted criminal that he is and turn him in to the authorities. Although Antonio is ultimately released he still ends up heartbroken as Sebastian ends up married to Olivia. In conclusion, Shakespeare shows us that love has two faces. One face shows us that love can be beautiful and can bring happiness, the other shows a darker and more painful side where love can be heartbreaking and mournful.Show MoreRelatedShakespeares View on Love Essay1971 Words   |  8 PagesShakespeare’s View on Love Shakespeare’s plays are very drastic with how he ties love into them.

Crew Resource Managament Essay Example For Students

Crew Resource Managament Essay WARNING!!! This is for ERAU Wildingers class. Dont even *think* of using this in his class!!! -strong message follows- Crew Resource Management 1Running Head: CRM AND AVIATION SAFETYCrew Resource Management and Aviation SafetySteven B. McSwainEmbry-Riddle Aeronautical UniversityCrew Resource Management 2AbstractThroughout the history of aviation, accidents have and will continue to occur. With the introduction of larger and more complex aircraft, the number of humans required to operate these complex machines has increased as well as, some say, the probability of human error. There are studies upon studies of aircraft accidents and incidents resulting from breakdowns in crew coordination and, more specifically, crew communication. These topics are the driving force behind crew resource management. This paper will attempt to present the concept of crew resource management (CRM) and its impact on aviation safety in modern commercial and military aviation. The concept is not a new one, but is continually evolving and can even include non-human elements such as computer-controlled limitations on aircraft maneuvers and the conflicts that result in the airline industry. Crew Resource Management 3Crew Resource Management and Aviation SafetySince the birth of aviation, man has been tasked with operating aircraft safely, yet effectively. From the beginning days of being able to simply operate an aircraft without injury for seconds at a time, to todays issues with safety in supersonic international travel, crew resource management has been with us in some from the beginning. The term CRM began to spread in the 1980s among the major airlines, fueled by industry and university research into human factors. The U.S. military has also taken a very active in the development of CRM techniques to aid in the high stress environment of military aviation. The basic concept of crew resource management (CRM) is to train crewmembers to use all available personnel, equipment, and expe rience to safely and effectively operate an aircraft. It is used in nearly every facet of aviation from the smallest regional airline, to the largest major carrier, to the various crew operated military aircraft. One aspect of aviation missing from the fold is the general aviation (GA) community, such as the private pilot. This has become a growing concern as many future air carrier pilots and military pilots begin as private pilots. The need for CRM training in this area is there, but the training seems excessive and useless to many in the field as most of these pilots operate single pilot aircraft. Perhaps this attitude comes from the term crew and is dismissed by the private pilot. This can be a dangerous attitude, as there is no doubt that sound decision making and the use of available resources should be a priority at any level of aviationTerms and Concepts Used in Crew Resource ManagementIn order to effectively explain the concept of CRM and its role in aviation safety, it is necessary to have at least a limited understanding of common terms and phrases. One of the two key elements of CRM is situational awareness, or, SA. Simply put, it is the understanding of Crew Resource Management 4the conditions surrounding your flight. Knowing what is happening, what has happened in the past and how that may affect your flight in the future. Situational awareness is probably best described as a conditioned state of mind while flying. It comes from experience and knowledge and can be blocked by being unfit to fly do to fatigue, for example. This concept is obviously a major consideration in flying all aircraft, but can be considered to be somewhat easier maintained in a crew aircraft than in a single pilot one. Another key concept in CRM is communication. This is a topic best described in its own publication, as there are numerous factors that contribute to successful or failed communication. There are many factors to be considered when analyzing communication in th e context of CRM, such as dialect. English is the universal air traffic language, yet it would be impossible to regulate accents and intelligibility of an air traffic controller or aircraft crew. This can obviously lead to missed communication between an American flight crew and Egyptian control facility, for example. Another aspect of the communication problem can be attributed to seniority in civilian aviation, or rank in military aviation. This barrier, fear of communication, must be overcome in order for a flight to safely operate. Each crewmember should be able to make input to the flight without fear of reprimand. Each person should provide feedback and be willing to accept a suggestion from other crewmembers. The last subject I will cover in regard to communication is standardization. Procedures checklists, operating instruction, and technical orders are written in a standardized form to avoid confusion and establish a common language. This usually results in a barrier of c ommunication in more experienced crewmembers. They can be so accustomed to the operating procedures that they expect everyone else to have the same level of understanding. This, combined with their usage of nonstandard verbiage can lead to deadly miscommunication in a worst-case scenario. Crew Resource Management 5A third commonly referred to concept in crew resource management is available resources. This can mean internal or external resources. Internal resources are things such as experience and knowledge, and having one does not necessarily require having the other. A crewmember can be experienced but not have a great deal of aircraft systems knowledge. Such as when in the military, as often happens, a pilot is transferred late in his or her career to another aircraft. That pilot may have over five thousand hours of flying experience, and even several hundred hours of combat flying experience. However, when arriving at a new assignment they have a very limited amount of aircraft systems knowledge in the new aircraft. This is also true for a civilian air carrier pilot who changes aircraft at some point in their career. External resources can consist of checklists or operating instructions, for example. This is an equally important factor in aviation safety, as can be seen by the report on the American Airlines crash in Columbia (Simmon, 1998). The failure to abide by these resources can have disastrous results. Many things can contribute to the breakdown in this area, most evident is fatigue combined with a high level of experience. An experienced captain can rely too much on knowledge and not enough on published procedure and guidance. Graffiti as Art EssayGeneral aviation, or GA, is severely behind in the development of CRM training. As a private pilot, I have noticed the absence of this training. After first being trained as a military crewmember, I noticed immediately the lack of CRM in any aspect of the training of the private pilot. Perhaps the reason I noticed this problem is the same reason many private pilots do not notice it. They have no experience, through no fault of their own, with the crew environment and its challenges and benefits. Though there is a small percentage of private pilots who will Crew Resource Management 8never operate in the crew environment, the majority begin this training as a step to a career in aviation, or at least to the point of flying with other people. Many are future small business pilots, many are future military pilots, and a few are future air carrier pilots. I personally used private pilot training to help prepare me for a career as a military pilot, but my situation w as unique as I stated before. The development of CRM in GA is beginning to be addressed, but is years behind that of commercial and military aviation. This is evident by the lack of continuity and availability of literature on GA crew resource management training (Santiago, 1996). ConclusionCrew resource management training is no doubt a vital part of flight safety. The programs have developed from crude briefings to sophisticated simulators and training techniques. The examples of the importance of this training can be found in almost every NTSB report of an incident involving the human factor of flight. I have attempted to bring to light the more important aspects of crew resource management, though the concept is much broader than I have presented. The basics of communication and problem solving are still the keys of CRM, and still seem to be the cause of most aviation accidents. The programs in effect to combat this problem are under constant development and analysis, in a hope to avoid these situations. The civilian industry continues to lead in development due to commercialization, with the military not far behind. The only real deficiency in CRM program development seems to be the area of general aviation as described earlier. Until this problem is addr essed, there will still be a glaring weakness in the general area of aviation safety. However, with the rate of technology increase and cheaper methods of instruction, we should begin to see this problem addressed in the near future. Until then, aviation will rely on civil commercial aviation the military to continue research and program development for the years to come, hopefully resulting in an increasingly safe method of travel and recreation.
