Dentistry And For Selecting Dentistry As A Profession Essay

. Give the reasons for your interest in dentistry and for selecting dentistry as a profession: There are several reason why I have decided to pursue a career in dentistry, one of them being my upbringing. Growing up in a socioeconomically disadvantaged family, I have watched my parents forgo essential medical treatment, in order to provide my siblings and I the basic necessities. For two decades, my mother sacrificed her oral health; overtime the lack of care took its toll and left her with diminished oralhealth. As a result my mother’s self-esteem suffered, greatly altering her personality. Watching my mother suffer due to a lack of proper oral care is the driving force in me to become a dentist. I want to be in a position to ease suffering and provide oral health care to those in need. Coming from an underserved community, I feel an obligation to give back to such communities. While volunteering at dental clinics, I have noticed the commonality of health disparities associated with those individuals from disadvantaged backgrounds. Often, those of lower socioeconomic status tend to put off seeking preventive dental services that often lead to chronic illnesses that are more difficult to treat. I find it heartbreaking to know people’s oral and overall health suffers because of their socioeconomic state. With the large number of dentists projected to retire in the upcoming years, there will be an increased shortage of dentists who are committed to providing oralShow MoreRelatedDental And Pre Medical Experience951 Words   |  4 Pageseach activity, dates of attendance, location, and description of your experience.

Additionally, the battleships carried two 21 torpedo tubes.  For protection, the  Wyoming-class utilized the main armor belt eleven inches thick.   Assigned to New York Shipbuilding Corporation in Camden, NJ, construction started  on Arkansas  on January 25, 1910.  Work advanced over the next year and  the new battleship entered the water on January 14, 1911, with Nancy Louise Macon of Helena, Arkansas  serving as sponsor.  Construction concluded the following year and  Arkansas  shifted to the Philadelphia Navy Yard where it entered commission on September 17, 1912, with Captain Roy C. Smith  in command. USS Arkansas (BB-33) - Early Service Departing Philadelphia,  Arkansas  steamed north to New York to take part in a fleet review for President William H. Taft.  Embarking the president, it then carried him south to the Panama Canal construction site before conducting a brief shakedown cruise.  Retrieving Taft,  Arkansas  transported him to Key West in December before joining the Atlantic Fleet.  Taking part in routine maneuvers during the majority of 1913, the battleship steamed for Europe that fall.  Making goodwill calls around the Mediterranean, it arrived in Naples in October and aided in celebrating the birthday of King Victor Emmanuel III.  Returning home,  Arkansas  sailed for the Gulf of Mexico in early 1914 as tensions with Mexico increased. In late April, Arkansas  took part in the US occupation of Veracruz.  Contributing four companies of infantry to the landing force, the battleship supported the fighting from offshore.  During the battle for the city,  Arkansas detachment sustained two killed while two members won the Medal of Honor for their actions.  Remaining in the vicinity through the summer, the battleship returned to Hampton Roads in October.  Following repairs at New York, Arkansas  began three years of standard operations with the Atlantic Fleet.  These consisted of training and exercises in northern waters during the summer months and in the Caribbean in the winter.   USS Arkansas (BB-33) - World War I Serving with Battleship Division 7 in early 1917, Arkansas  was in Virginia when the US entered World War I that April.  Over the next fourteen months, the battleship operated along the East Coast training gun crews.  In July 1918,  Arkansas  transited the Atlantic and relieved USS  Delaware  (BB-28) which was serving with the 6th Battle Squadron in Admiral Sir David Beattys British Grand Fleet. Operating with the 6th Battle Squadron for the remainder of the war, the battleship sortied in late November along with the Grand Fleet to escort the German High Seas Fleet into internment at Scapa Flow.  Detached from the Grand  Fleet on December 1,  Arkansas  and other American naval forces steamed for Brest, France where they met the liner SS  George Washington  which was carrying President Woodrow Wilson to the peace conference at Versailles.  This done, the battleship sailed for New York where it arrived on December 26. USS Arkansas (BB-33) - Interwar Years In May  1919,  Arkansas served as a guide ship for a flight of US Navy Curtiss NC flying boats as they attempted a trans-Atlantic flight before receiving  orders to join the Pacific Fleet that summer.  Passing through the Panama Canal,  Arkansas  spent two years in the Pacific during which time it visited Hawaii and Chile.  Returning to the Atlantic in 1921, the battleship spent the next four years conducting routine exercises and midshipmen training cruises.  Entering the Philadelphia Navy Yard in 1925,  Arkansas  underwent a modernization program which saw the installation of oil-fired boilers, a tripod mast aft, additional deck armor, as well as the trunking of the ships funnels into a single, larger funnel.  Rejoining the fleet in November 1926, the battleship spent the next several years in peacetime operations with the Atlantic and Scouting Fleets.  These included a variety of training cruises and fleet problems. Continuing to serve, Arkansas  was at Hampton Roads in September 1939 when World War II began in Europe.  Assigned to the Neutrality Patrol reserve force along with USS  New York  (BB-34), USS  Texas  (BB-35), and USS  Ranger  (CV-4), the battleship continued training activities into 1940.  The following July,  Arkansas  escorted US forces to the north to occupy Iceland before being present at the Atlantic Charter conference a month later.  Resuming service with the Neutrality Patrol, it was at Casco Bay, ME on December 7 when the Japanese attacked Pearl Harbor. USS Arkansas (BB-33) - World War II Following training activities in the North Atlantic,  Arkansas  arrived at Norfolk in March 1942 for an overhaul.  This saw a reduction in the vessels secondary armament and an enhancement of its anti-aircraft defenses.  After a shakedown cruise in the Chesapeake,  Arkansas  escorted a convoy to Scotland in August.  It repeated this run again in October.  Beginning in November, the battleship began protecting convoys bound for North Africa as part of Operation Torch.  Continuing in this duty until May 1943,  Arkansas  then moved to a training role in the Chesapeake.  That fall, it received orders to aid in escorting convoys to Ireland. In April 1944, Arkansas  commenced shore bombardment training in Irish waters in preparation for the invasion of Normandy.  Sortieing on June 3, the battleship joined Texas  in Group II before arriving off Omaha Beach three days later.  Opening fire at 5:52 AM,  Arkansas first shots in combat struck German positions behind the beach.  Continuing to engage targets through the day, it remained offshore supporting Allied operations for the next week.  Operating along the Norman coast for the rest of the month, Arkansas  shifted to the Mediterranean in July to provide fire support for Operation Dragoon.  Striking targets along the French Riviera in mid-August, the battleship then sailed for Boston. Undergoing a refit,  Arkansas  prepared for service in the Pacific.  Sailing in November, the battleship reached Ulithi in early 1945.  Assigned to Task Force 54,  Arkansas  took part in the invasion of Iwo Jima beginning on February 16.  Departing in March, it sailed for Okinawa where it provided fire support for Allied troops following the landings on April 1.  Remaining offshore into May, the battleships guns bombarded Japanese positions.  Withdrawn to Guam and then the Philippines, Arkansas  remained there into August.  Sailing for Okinawa late in the month, it was at sea when the word was received that the war had ended. USS Arkansas (BB-33) - Later Career Assigned to Operation Magic Carpet,  Arkansas  aided in returning American servicemen from the Pacific.  Employed in this role through the end of the year, the battleship then remained at San Francisco through the early part of 1946.  In May, it departed for Bikini Atoll via Pearl Harbor.  Arriving at Bikini in June, Arkansas  was designated as a target ship for the Operation Crossroads atomic bomb testing.  Surviving Test ABLE on July 1, the battleship was sunk on July 25 following the underwater detonation of Test BAKER.  Officially decommissioned four days later,  Arkansas  was struck from the Naval Vessel Register on August 15.

Descriptions And Categories Of Hurricanes Environmental Sciences Essay Free Essays

Introduction Hurricanes are tropical storms with air current velocities transcending 74mph. They typically occur over oceans and get down their formations from the equatorial parts of the universe. They are really complex conditions phenomena that are still hard to understand. We will write a custom essay sample on Descriptions And Categories Of Hurricanes Environmental Sciences Essay or any similar topic only for you Order Now They are besides called tropical cyclones and typhoons. in order for them to be classified in 1969 by Saffir, H and Simpson, B. developed a graduated table which is used to categorise them, this is refered to as the Saffir-Simpson graduated table. They range from least harmful to the most harmful ranging from class 1-5 ( Katsaros et al, 2002, ) . Hurricanes are normally accompanied by storm rushs. In order to understand the character of hurricanes the ambiance over oceans are continuously observed by assorted conditions orbiters in infinite, and other aerial detectors. Storm surges normally accompany hurricanes.

Remote Sensing of hurricanes. As a consequence of their really destructive nature, hurricanes are monitored by orbiters and aerial remote feeling engineerings. The type of detectors used scope from the optical, micro-cook and non merely by conditions orbiters but by several other orbiters. In the instance of exigencies other orbiters are besides used to supervise hurricanes. Table 2 below shows some of the orbiters and aerial detectors that are used in the instance of exigencies to supervise hurricanes. Optical and micro-cook orbiters are frequently really critical in supervising hurricanes as they tend to come on. Due to their big spacial declarations, they can be used to track the flight of hurricanes. These optical imagination are besides sometimes used in the absence of Radar techniques, to analyze the physical belongingss of hurricanes. These physical belongingss include: liquid H2O way, thermodynamic stage of atoms and their approximative size ( Kokhanovsky A ; Hoyningen-Huene, 2004 ) In order to supervise hurricanes as they progress, in order for hurricanes to be understood in the context of its character and physical belongingss, microwave orbiters provide seasonably atmospheric coverage as they can perforate clouds and due to their long wavelengths and work irrespective of twenty-four hours or dark. ( Navalgund et al, 2007 ) . Scatterometers, Man-made Aperture Radar and micro-cook radiometers are some of the instruments uses in microwave remote feeling. While Scatterrometers and Man-made Aperture Radar are active detectors breathing their ain energy, Microwave Radiometers merely step reflected energy transmitted to it as it is a inactive detector. Scatterometers are used to mensurate surface air current velocities and way. They measure ocean surface raggedness and are really sensitive instruments. If the air current velocity is non Of all the declarations, a high temporal declaration is the most of import in tracking the way of a hurricane. This is non to state that radiometric, spectral and spacial declarations are non of import. This is necessary in order to adequately foretell the way of the hurricane and to efficaciously supervise its advancement to state if its strength is reduced or increased. Besides, information and information about hurricanes can easy go out-of-date as as the hurricane changes its class. Timely airing of informations from a hurricane is necessary in order for the terminal usage which might be a catastrophe monitoring bureau to accurately circulate information to the general populace. Besides, a high spectral declaration is needed in order to easy separate between sets, to be able to properly analyse informations presented. Moderate Resolution Imaging Spectrometer ( MODIS ) has really high spectral declaration of 32 sets when compared with Landsat Thematic plotter which has 7 sets ( Womble et al 2006 ) . In the trailing of the hurricane, a really larger spectral declaration will find the peculiarity between sets and the ability to spot information. Determining the perpendicular construction of the ambiance requires a high spectral declaration infrared observations. ( Schmit et al 2009 ) . Synergy or a combination of the assorted distant feeling engineerings frequently produce the best information needed to understand hurricanes. In a study carried by MCEER in the aftermath of hurricane Katrina, it was found that earlier forcasts about the class of the storm was incorrect. By uniting informations from assorted assorted orbiters, the true magniturde of the hurricane was determined ( Womble et al 2006 ) . Future tendencies in hurricane forcasting will concentrate on bettering spectral declaration in order to be able to easy demonstrated engineering such as the advanced IR sounder engineering will enable â€Å" A geostationary advanced IR sounder would supply breakthrough measurings on the clip development of horizontal and perpendicular H2O vapour and temperature constructions. These measurings would be an unprecedented beginning of information on the dynamic and thermodynamic atmospheric Fieldss, an of import benefit to nowcasting and numerical conditions anticipation † ( Schmit et al 2009 ; 2274 ) A high radiometric declaration on the other manus will take to greater peculiarity in images. The higher the spectral declaration of the image, the more characteristics can be distinguished. The areal extent covered when tracking a hurricane should non be so much in order for the Instantaneous field of position non to be excessively much. In accessing jeopardies after the hurricane, a spacial declaration is needed. As u can non hold it all, trade offs are made and determinations as to instruments which can integrate all of these features possibly will give better apprehension of hurricanes.Table 2: Distant feeling informations used in hurricane monitoring. â€Å" Beginning: Womble et Al ( 2006 ) † REMOTE SENSING OF HURRICANES The first conditions orbiters which were launched provided planetary coverage of conditions events and due to their low spacial declarations. They besides had high temporal declarations supplying seasonably updates every bit frequently as every 30mins. These orbiters include APPROPRIATENESS OF REMOTE SENSING TECHNOLOGY TO SOCIO ECONOMIC SITUATION The socio-economic stableness attained by the western universe has enabled her to accomplish and be able to develop and afford really expensive engineering such as distant detection. The placing of orbiters in infinite whether Geostationary or polar orbiting and the usage of other signifiers of airborne ( aeroplanes, balloons etc ) Remote Sensing Technology, the benefits derivable from timely warning of catastrophes such as hurricanes can non be of all time emphasized ( Murthi A ; Madhusudan 2008 ) . Without this engineering natural happenings such as hurricanes can non be predicted. Remote feeling engineering by enabling early sensing of natural catastrophes and triping off widespread warning enables catastrophe warning and catastrophe direction proparations to be carried out. Disaster direction organic structures such as FERMA, seashore guard both of the united provinces are better equipped to work decently and can assist salvage 100s of 1000s of lives and harm to belongings can besides be reduced. â€Å" Satellite observations of land, oceans, atmosphere, and specifically, during natural and human-induced jeopardies have become important for protecting the planetary environment, cut downing catastrophe losingss, and accomplishing sustainable development † ( Navagundi et al 2007: 1747 ) . As a consequence of timely warning of impending catastrophes, concerns are given early warnings and can shut on clip, and belongingss which can be moved out of injuries manner were moved. In 1992, hurricane Andrew destroyed about 25,524 places and damaged another 101,241 taking to estimated amendss of $ 25billion. Besides, in 2005 hurricanes Denis, Katrina, Rita and Wilma caused huge amendss amounting to $ 32.83 billion ( Otero et al 2009 ) . IMPORTANCE OF REAL TIME REMOTE SENSING TECHNOLOGY In supervising hurricanes as they grow and advancement, existent clip information or information is required as information can easy go out-of-date. Timely data entree and airing is really of import peculiarly in hurricanes. Although satellite engineering provides information about hurricanes they do non demo plenty item to be able to really accurately predict their tends or proctor hurricanes. NASA normally flies aircraft into the oculus of the hurricane to be able to acquire more item about the hurricanes. In cases when it is excessively unsafe to wing, aircrafts that do non necessitate worlds are flown into the hurricanes to be able to acquire more inside informations and timely updates. Hurricane Katrina presented new frontiers for research as it showed oversights in satellite anticipations. Initial premises based on the safir-simpson graduated table declared hurricane Katrina as a class 4 storm. Latter ratings utilizing a synergism of low declaration orbiters, moderate declaration orbiters, high declaration orbiters and high declaration aerial imagination showed that it was a class 3 storm and that the sum of devastation that accompanied it was a consequence of the storm rush which was still category 5 ( Womble et at 2006 ) . Detailss of the orbiters and their declarations is given below in table 2. Had the exact strength of the storm rush been known before Katrina hit, there would hold been a more equal readying and exigency response. REFEERENCES Dabas, A.

Management Methodology & Project Success-Free-Samples for Students

Questions: 1. Define what a methodology is and the role it serves in Project Management. 2. Familiarise yourselves with the various methodologies in the list below. Choose two methodologies from this list to compare and contrast, analysing the similarities and differences between them both. 3. Finally, identify how your chosen methodologies and processes relate to the project life cycle (PLC). Answers: 1.Define what a methodology is and the role it serves in project management. A methodology can be defined as a model where project manager is able to involve in different designs along with planning, execution and accomplishment of the present objective of the project. There are multiple methodologies in project management in order to gain advantage through different projects. For instance, there is particular kind of methodology used by a organization like NASA. The organization utilizes it to build a specific space based station while the Navy wanted to take a different route and use different methodology to build multiple kinds of submarines (Joslin Mller, 2015). Therefore, there are distinct project based management methods that can cater to the requirement of different kinds of projects spanned across distinct business areas. In the current time, projects are usually large in size and very complicated with important involvement of huge risk. These complicated projects consist of the following: - Different kind of delivery units with subcontractors as well as vendors with number of customer based personnel. There functions are based on delivery that the company must get involved in and organize properly (Kerzner, 2013). There are different kinds of contracts for software, tools, hardware as well as services like business analysis, training related communication and in the end installation. It is important to have a synchronized vision where project that can meet the customer needs and are acceptable to all kind of parties. Different kind of user interacts in varied geographic location distributed evenly. There are different kind of technologies like LAN, WAN, routers, animation, artificial intelligence and many more. These all should be harnessed in an effective manner as well as integrated to deal with the need of customers and their expectations (Marcelino-Sdaba et al, 2014). 2.SDLC and Waterfall model SDLC is also called as a software development life cycle model which is taken as a structured way to develop a software. There are different kinds of activities done in a more sequence form to accomplish the end product (Alshamrani Bahattab, 2015). Every phase is connected with a lot of deliverable that function as an input to the additional phase of SDLC. Following are some of the popular SDLC models: - Waterfall modelIncremental life cycle modelV-shaped modelSpiral model The report will discuss in detail about waterfall model which is considered as one of the most popular models of SDLC (Mahalakshmi Sundararajan, 2013). This model has to offer different kind of deliverables for every phase. This model also offers the following advantages: -The model is simple and can be executed in an easy manner.The model follows a linear form of approach and this is why it can be managed easily.Every phase is implemented once in a timeframe (Mahalakshmi Sundararajan, 2013).The project is utilized best for projects which are small in size. Following are some of the disadvantages: - It involves a high-risk factor.It cannot be advantageous for large projects.It is not flexible by nature so if the requirements are changing during the project, it cannot be used (Mahalakshmi Sundararajan, 2013).It is not best suited for complex projects. 3.Identify how SDLC and waterfall model relate to the project life cycle. Following are the ways in which these models can relate to PLC:-It is important to have a stable product definition.It is important to have a clear technology.There should not be any requirements which are ambiguous by nature. It is important to understand here, that a very small number of customer communications is involved at the time of development of the product (Saxena Upadhyay, 2016). When the product is ready to use, only then it can be exposed to end users. But, if there is any failure about it development and exposure to end users, the cost of fixing it is very high at this point because updating process is required at every phase.
