Hindenburg Disaster

On May 6th, 1937, a Zeppelin airship of Germany called the Hindenburg set off for its first North Atlantic crossing. It was to land on Naval Air Station base in Lakehurst, New Jersey but fate had a different plan for the Hindenburg and its passengers. At 7:20, reporters and crowds gathered around to see the sky-beauty land in her appointed spot, but at 7:23 screams were heard and the sound of a firework shooting up. To the crowd’s amazement, they saw a small, orange flame forming at the tail end of the airship. The fire started at the top tail fin or so it has been reported by eye witnesses of this horrific disaster.The designer of the Hindenburg had law enforcements give the witnesses a blueprint of the airship so they could illustrate where they seen the small flame and how they saw the fire spread across the dirigible. When everything was said and done and they reviewed the blueprints that were collected not one was identical to the one before or after it. Some saw a flash, some saw a spark, and some saw an explosion. The cause, to this day, has been unknown. There are theories floating around such as: static electricity from the on coming thunderstorm, a small lighting bolt, a leak of hydrogen, conspiracy, and many others that have no backing agents.In the following sections I will have hoped to help you make you decision on what the real cause of this tragic event was and in detail explained what I think happened and why with a scientific explanation. First, what was the structure of the Hindenburg made of? The skeleton was made of an aluminum structure. The blimps design was 15 main rings made of aluminum making the central frame. Then the remaining frame was welted to those 15 rings then covered with non flame-retardant cotton. Then the cotton itself was painted. It was painted with cellulose acetate butyrate and aluminum powder, both of which can be combustible alone.Aluminum powder can be explosive or flammable if mixed with air, it is used in l iquid and solid rocket fuels, and used in thermite, which is an incendiary. It also burns and orange-red depending on other elements being present at point of ignition. The cellulose acetate butyrate is combustible and used in everyday items such as hairbrushes. Thought it was painted with the same substance throughout it was not painted with the same amount of coats throughout. The top had more layers of â€Å"dope† paint to sustain from lighting strikes and the bottom was painted with a top coat of reflection â€Å"dope† paint to fool the people below.Inside the Hindenburg, there were 16 gas filled pockets. These pockets were filled with hydrogen instead of helium because it is less dense than Helium. (Side note: The fact that hydrogen is less dense than helium is proven because of Avogadro. He stated that if you have two different gases at the same pressure and the same temperature then they would have the same amount of particles. But then that would lead to say th at one mol of helium has a mass of 4 grams and one mol of hydrogen has a mass of 2 grams. The pockets or gasbags were lined with goldbeater’s skin, a thin membrane taken from cattle intestines. The Hindenburg as a whole was almost the size of the Titanic. There are many theories to what caused the Hindenburg fire. Suggestions such as: the pain caught fire from a spark that came off the rope being deployed at the landing destination, or the hydrogen being released had caught a spark or a lightning bolt, a Nazi soldier set the airship on fire, or a witness from below shot the tail end of the dirigible causing it to catch fire.Though these theories have been backed by countless number of reasoning’s and facts no one scientist can fully prove the cause of the fire. There is one theory that could have been but more than likely it did not. The theory of conspiracy. Though it is true that a handgun was found in the remains of the Hindenburg, it is not a plausible answer to th e massive disaster. It is said that a Nazi purposefully shot one of the hydrogen bags while walking the axis of the airship. Considering the Hindenburg was an anti-Nazi dirigible and even its creator did not support Hitler and his rampage, it is not a creditable theory.Though it is a food for thought, the conspiracy theory has no backing or relative cause of purpose. Addison Bain, for example, tried to show that the thermite paint caused a reaction. In his paper he went on to say that a spark from the engine had landed on the paint and contained enough energy to set fire to the paint and cause the fire. Though he is not completely wrong, personally it is not a well-enough explanation to what happened and how it happened. Bain had preformed television demonstrations on his theory, but he had flaws in his experiments.For instance, he showed a continuous flame one the skin on the Hindenburg model and his research shows that he concluded it to be an instant spark. On another count, he u sed a small piece of the actual skin cover in the â€Å"dope† and he set it on fire and showed its burn time, if these were correct tests he should have allowed reaction time, set fire in relative area of the original fire, the tail area not its mid section, and did not consider the dampness of the â€Å"dope† paint at the altitude it was at. These were also factors going against whether or not the Mythbusters had correctly called their test on Bain’s theory a bust.In the television series Mythbusters, Adam and Jamie gather myths that have been sent in by their viewers, myths that are not able to be determined busted on a day-to-day basis, and they safely determine if the myth is true and factual or is it a rumor and a hoax. Mythbusters determined that the theory proposed by Addison Bain was a bust. They built three models of the Hindenburg on a 1/50th scale and conducted three different experiments. One Hindenburg was painted with the â€Å"dope† and fil led with air. The second was just the hydrogen within with a regular skin without the â€Å"dope† compound.The third consisted of both the â€Å"dope† skin and the hydrogen filling. They determined that the hydrogen was the real cal prate of the Hindenburg fire. Considering the way they tested the experiments, it is very arguable to say that they did not correctly perform their experiments. For instance they did not set fire at the tail end of the dirigible. They also set a direct flame and not an initial spark to the paint. In addition, when they set fire to a small portion of the skin covered in â€Å"dope† they did not allow a reaction time. Reminder that witnesses said they saw an orange-red flame at the tail end of the dirigible. ) While examining the mystery of the Hindenburg, you will notice that at 7:20 the crowd has noticed a slight spark at the tail end; and at 7:23 the airship has started to come down in flames. It took approximately 24 seconds for th e Hindenburg to burn from tail to nose. The Mythbuster gang’s Hindenburg models took times that consist of 1 minute and 37 seconds, 57 second, and 52 seconds. In order to declare this busted, one must allow for every possible variable that could have been presented on May 6th in New Jersey.Other factors that could pose a problem against the Mythbusters are considerations that any man can conjure up and present. For example, the experiment was conducted inside and on the day on the disaster there was a high wind issue. In order for fire to burn rapidly it has to have a large supply of oxygen. The atmosphere consists of nitrogen, hydrogen, and oxygen, oxygen is most of that. Another problem could have been that the Hindenburg had gasbags filled with hydrogen and the Mythbusters â€Å"generally† filled the down-scale model with hydrogen, not separating the â€Å"dope† paint skin and the hydrogen contact.If the skin would have been directly lying on the hydrogen in the Hindenburg, it would have taken far less time to burn or might have actually â€Å"exploded†. Another myth that has spread widely is that the Hindenburg was painted with pure rocket fuel. As stated previously, the â€Å"dope† consisted of aluminum powder and cellulose acetate butyrate. Though it contains rocket fuel ingredients it is not painted fully and only rocket fuel. It is also and ingredient in thermite incendiary, which explains why scientist concluded the Hindenburg fire to be a thermite reaction. Fe2O3+2Al ? Al2O3+2Fe) is the chemical equation for a thermite reaction. A thermite reaction is an exothermic reaction. Meaning when its compounds react with one another they put off heat instead of absorbing energy, or an endothermic reaction. Also, when you burn metals together they tend to have a orange or red flame†¦ the Hindenburg burnt orange-red) Aluminum powder was in bedded in the â€Å"dope† compound. This byproduct is mostly found in the co ntents of rocket fuel or rocket propellants.It is often mistakenly said that the Hindenburg was painted with rocket fuel but this conclusion is only partially correct. The aluminum powder itself, if extremely fine, can form flammable and explosive mixtures in the air. Basically, the Hindenburg was not painted with rocket fuel. The next suggestion is that the Mythbusters did not allow for weather conditions to be taken into consideration. On May 6th, 1937, it was told to be raining which is a reason the Hindenburg did not land at it designated time. It was delayed over the Atlantic for several hours.Some scientist have asked, if it had been a spark that ignited the paint then it would have had to generate enough energy to first evaporate dew off of skin and then still possess enough energy to ignite the â€Å"dope† on the skin. Once again, the skin was made of aluminum powder and cellulose acetate butyrate. CAB contains low moisture absorption. It effectively resists weatherin g and ultra-violet radiation. Though it is not effective against alcohol, alkalis, paint removers, and acetones. Since the compound contained aluminum powder, an alkaline metal, could this have over powered it so the â€Å"dope† paint absorbed a small amount of water?It could have, but only if the aluminum powder was in a ration of 50 to 1. It might have been wiser for the German makers to obtain helium rather that hydrogen. Helium does not burn. It is a monatomic gas, or having replaced one atom. Since helium already contains 8 electrons it is a noble gas. This property makes it highly un-reactive because it is already considered to be happy with its eight electrons in its outer most shell. The problem with using hydrogen in the Hindenburg is that it only contains one valence electron which can cause it to highly reactive to almost any element it comes into contact with.The wiser decision for the makers of the Hindenburg would have been to use the less reactive helium instea d of the highly reactive hydrogen. In conclusion, I believe the hydrogen is not the cause of the Hindenburg disaster. Though it is a major factor with its rapid fire spread it is not the main cause. In my opinion, the cause is that a small lighting bolt had hit where the body and the tail fin connected. Where the covering of the body tries to match that of the tail fin. This makes sense because the tail fins were coated with a lighter coating of the â€Å"dope† paint. This is the location the hydrogen is being released.A spark hit the paint at this specific spot causing the paint to ignite and causing a chain reaction with the paint and the hydrogen. If hydrogen was being released at a specific temperature and a specific pressure around the area of ignition, it may have caused the â€Å"explosion† on the Hindenburg. When hydrogen comes in contact with a flame the hydrogen extinguishes the flame, but when a combination of hydrogen along with air (oxygen) are presented w ith a flame, the hydrogen will persist to terminate the flame but then the air with reignite it. This is because a fire cannot burn without the presence of oxygen.Additionally, a hydrogen reaction (2H+O2? 2H2O) is an exothermic reaction, the same as the thermite within the â€Å"dope† paint. With the hydrogen putting of heat when it reacted and the thermite releasing heat as it reacted it caused the temperature of the skin to increase to an immeasurable heat. This most likely caused the aluminum powder within the â€Å"dope† to become a lose particle in the air. Another point that may have added to the release of the aluminum powder could be the Hindenburg had been hit before by lightning bolts and caused small burn holes on the top half of the Hindenburg and caused no fire.Analyzing that the statement before is true, there may have been a chance that the aluminum powder from the â€Å"dope† paint could have escaped where the lightning bolt had struck. Therefore it caused a reaction between the oxygen in the air and the aluminum powder. Furthermore my conclusion is the hydrogen is not the initial cause of the fire but the â€Å"dope† paint itself. Again this is my opinion and you, as the reader, are free to interoperate the data and conclude to your own opinion because to interoperate the true cause of the Hindenburg is a personal preference one must do on one’s own.

Accountable Care Organization

Accountable Care Organization Ralph Edwards Grand Canyon University Operations in Risk Management in Health Care HCA-460 Dr. Smith March 24, 2013 ACO Even although, the cost of the health care system and the care it offers my not allow the national debt to decline to a level that will or would enhance the economy forward the cost of running a system that is backed by the government is too costly, and it will not help the deficit. , the legal responsibility of the organization is that every patron should have the same treatment for the same ailment.There are no predetermined dispositions; everyone is eligible as a government-backed facility. The funds are to assure those who have no insurance are covered. The accountable care organization needs to sustain a system of health care to the elderly and financially handicap; no one turned away from health care under this system of care. Including but not limited to the handicap and mentally disturbed and during the implementation of the ACA for the elderly, the system allowed all who need care to continue to have health care.All who live in America have the right and the ability to use the systems health care services for their benefit. The legal responsibility of the ACA has shown itself to be of value to all who depend on this system of care. What is the organization's legal responsibility? the legal responsibility of the organization is that every patron should have the same treatment for the same ailment. The ACO answerable to a third party payer and the patient for the appropriateness, quality and proficiency of care delivered.The Centers of Medicaid and Medicare Services (CMS), and the ACO is â€Å"health care providers of an organization which approves accountable services of quality, overall care, and quality of Medicare beneficiaries enrolled by the traditional fee-for-service program that are assigned to it. † Medicare (2010). The cost of running a system that backed by government funds is too costly, and it will not help the deficit. The potential for quality is to reduced, improve and the care while healthcare spending with high expenditures nationwide.However, the ACO’s have many challenges that affect their implementation for the development of ACO’s. First, lack of specificity on how the ACOs can and will implement. The American Hospital Association estimated the formation of ACOs would create startup cost that is staggering with expenses annually too large to maintain systems, American Hospital Association. (2011). There are three core principles to any ACOs. First, provider-led organizations with primary maintenance and a strong base are liable communally and total per capita costs for quality with full continuum for the population of care for patients.Second, excellent improvements will have linked to also have complete costs reduced, and third, progressively and reliable sophisticated measurement performance to improve, support, and provide the savings of confidence are achieved with improvements of care, , McClellan M, McKethan AN, Lewis JL, Roski J, Fisher ES (2010). The cost of running a system supported by government resources is too costly, and it will not help the deficit. The organizations responsibility for the regulatory practices of the ACO with the best method to improve quality and greater collaboration of care providers that will reduce cost.Unavoidably, the infrastructure would result with consolidation, coordination in the sector of health care. The Department of Justice and the Federal Trade Commission address the ACOs concerns and developed rules that would regulate their actions over the market power the collude improperly dealing with commercial health plans. This action would not barricade the operation and or formation of the ACOs as Medicare payment reform, McClellan, Mark, et al. (2010). The Advanced Medical Technology Association, which represents MDI, believes that the system may allow the ACOs to emphasis on cost rather than quality of care.CMS would rather see beneficiary’s stronger oversight, which would require annual consents to ACOs to provide care. â€Å"David Nexon, stated that innovation and the process of medical progress is the willingness of the dependent person’s to early medical adopters, which can interrupt that early process of the ACO, senior executive vice president at AdvaMed. In addition, CMS in regards to Medicare should monitor the program. New technology users should not be penalized and the cost should be based on savings and not by any one physician, Jaimy Lee ( June 2011). The overnment will pay the fee for services rendered, traditionally to the ACOs. There is an increase in the cost of health care, experts contend because Medicare programs paid doctors that ordered substantial test for their patients. CMS shall cover expenses incurred for the caring of their patients, one payment received by ACOs. The cost is considered and the extra kept if pa tients are healthy with prevention methods and managing chronic diseases. Quality assessment benchmarks must be stringent and must include the consequence, experiences, and private process to be suitable (aha. rg, 2012; Gold, 2012). The oversight process of the ACOs had apparatuses, which include but not limited to regulatory environment: Federal Jurisdiction, 3022 of PPACA, and many other oversight processes that administrate the system. The established ACOs outcome is determined, although CMS prays for method used, paved as to return to collegiality patient atmosphere to normality. Therefore, you can see that although the cost of running a system backed by government funds is too costly, and it will not help the deficit.The legal responsibility of the organization is that every patron has the same treatment for the same ailment, for two main reasons. First, there are no predetermined dispositions everyone is eligible, but most importantly, as a government backed facility the funds that are mandated to assist those who have no insurance are covered. As ACOs becomes more established and maintains the government’s idea and the public’s capacities on health care with reducing cost and heightened quality, balancing the enormous entity will have a profound effect on the public’s outlook of our government directed systems.The public will undoubtedly respond positively and back the direction of the systems directors and administrators. With the potential of improving quality care and reducing a nations expenditures in health care ACOs still face an abundance of challenges the will affect the ACOs implementation and development. The absence of how the implementation and the AHA estimated and incur startup cost that is sky high The United States Department of Justice. (2011).

Simulation of low vision Essay Example | Topics and Well Written Essays - 1000 words

Simulation of low vision - Essay Example Visual performance may be affected. A person with low vision can use her reduced vision for learning about the world and for planning and doing tasks that need vision† (Low Vision, 2008). The IDEA Amendments of 1997 have yet another definition. They define children with visual impairment as those who have â€Å"visual impairments which even with correction, adversely effects†¦ educational performance.† 1. Generalization of skills: Many students with visual impairments may exhibit difficulty transferring skills acquired in one context to anther. It is important that instruction takes place in natural contexts and at appropriate times so the students internalizes meaning to the task. 2. Concrete versus abstracts learning: some students with visual impairments require hands-on learning experiences through their educational program in order to make sense of concepts and strategies for instructions that are more abstract. Often, the only way that students can learn new skills is through repetitive learning. For example, students who have visual impairments and exhibit cognitive delays may be taught a specific route to the cafeteria. Any change in route may confuse the student. 3. Attention span and distractibility: when initiating instructional programs for students who have visual impairments and other disabilities, the teacher must determine how long a student can attend to a specific task with and without supervision. Also, the environment is an influence on the student’s ability to stay on task and to maintain appropriate behavior. Many students with visual impairments are distracted by loud noises. Examples include the hum of fluorescent lights, a visually cultured classroom, and verbal communication by others in the same environment. They require auditory, tactical, or visual cues to anticipate the transition from one activity to the next. 4. Auditory versus visual learning: most students with visual impairments

Deaf In Prison Assignment Example | Topics and Well Written Essays - 500 words

Deaf In Prison - Assignment Example (4) According to recent research due to lack of adequate policies to protect inmates, many deaf prisoners are exposed to abuse from the other inmates as soon as they enter prison. Unlike other prisoners who have access to telephone and educations privileges, many penitentiary systems fail to offer deaf telephones and interpreter services for educational purposes among other essential services.(2) According to recent research, many deaf and hard of hearing inmates report that they are faced with difficulties of trying to express themselves in court and in prison. Many deaf prisoners are exposed to abuse from the other inmates as soon as they enter prison in the form of physical assault. (1) According to recent reports, disabled inmates are constantly abused by other prisoners aided by the fact that local, state and federal prison officials, blatantly fail to enforce laws aimed at protecting the deaf. In a recent court case, the court found evidence of prison system malfeasance for failing to inform deaf prisoners of their accommodations. Due to their inability to hear, these inmates often fail to respond to bells, instructions from prison guards and they get punished for their perceived insubordination. According to statistics, only half of spoken sounds are translated to sign language. (1) Majority of the U.S penitentiary systems are not handicap enabled for deaf prisoners. Deaf prisoners usually lack access to visual alarms and interpreter services for drug and alcohol counselling, parole, disciplinary and grievance hearings and mental health treatment. (3) Some of the measures proposed include implementation of the Americans with Disabilities Act and the Disabilities Education Act, which are to be implemented in all governmental institutions including prisons. The Supreme Court also ruled that prison systems would be held accountable for violating laws mandating them to inform deaf prisoners of their accommodation. Other

Rockwell Hardness Testing Lab Report Example | Topics and Well Written Essays - 1000 words

Rockwell Hardness Testing - Lab Report Example Hardness is a measure of the resistance of a metal to permanent (plastic) deformation. The hardness of the metal is measured by forcing an indenter into its surface. The indenter material which is usually a ball, pyramid, or cone, is made of a material much harder than the material being tested. For example, hardened steel, tungsten carbide, or diamond are commonly used materials for indenters. For most standard hardness tests a known load is applied slowly by pressing the indenter at 90 degrees into the metal surface being tested. After the indentation has been made, the indenter is withdrawn from the surface as shown in the figure. An empirical hardness number is then calculated or read off a dial (or digital display), which is based on the cross-sectional area of depth of the impression. The hardness of a metal depends on the ease with which it plastically deforms. Thus a relationship between hardness and strength for a particular metal can be determined empirically. The hardness test is much simpler than the tensile test and can be nondestructive (i.e., the small indentation of the indenter may not be detrimental to the use of an object). For these reasons, the hardness test is used extensively in industry for quality control. The Rockwell Hardness test consists of many different scales for a range of different hardnesses. The B and C scale are the types used in this experiment. The B scale uses the spherical steel penetrator and the C scale uses the diamond cone shaped penetrator. Procedure for Experiment 1. Make certain the crank .It is kept in forward position, nearest to you. 2. Place the sample on the anvil, in position for test. 3. Select 100 and 150 kg combination of weights (being at the rear of the machine) . 4. Slowly turn the wheel spokes clockwise. This raises the anvil and sample toward the penetrator tip. After contact is gently made, continue raising sample until small pointer is about in line with the small black dot and the large pointer is within the colored sector. The minor load has now been applied to the sample. 5. After step 4, the large pointer on the dial is nearly vertical. Now, turn the knurled collar until the SET line on the dial scale is in line with and under the large pointer . 6. Depress the trip lever. This triggers the mechanism that applies the major load. The crank will automatically move away from you. 7. After the crank has come to rest, gently pull the crank back toward you as far as it will go. If this is done abruptly, a false reading

Malaria Essay Example | Topics and Well Written Essays - 1250 words

Malaria - Essay Example In actual fact, Malaria is still the leading cause of morbidity and mortality in many parts of the world and more especially in sub-Saharan Africa. Therefore, it is an indication that the tools available for malaria control are neither adequate nor good enough for the prevention. Therefore, participating in malaria clinical trial will help in finding a permanent solution for this disease as together with other researchers we try to find curative and preventive drugs and vaccines for malaria. Additionally, by getting involved in malaria clinical trial I will be able to have a chance to propagate and advocate a malaria vaccine and make it available for routine use. Moreover, I will be able to offer my own ideas and notions about this terrible disease as well as get to know qualitative and quantitative methods for data collection purposes especially in Africa. This will help to know how endemic is this disease and also facilitate in finding a malaria vaccine which will be more efficacio us than the malaria drug which has been used from time immemorial as a malaria control tool. To be precise it is clearly known that malaria is a tropical disease and is spread by female Anopheles mosquitos which are infected by a plasmodium parasite. Therefore, this plasmodium falcipavum malaria causes millions of clinical episodes globally but mostly endemic in sub-Saharan Africa. Malaria involves diseases such as shaking chills and high fevers among others. In countries like Ghana malaria claims so many lives of children and in 2008 only there were numerous deaths of children under the age of twelve years. Malaria can leads to cerebral malaria and anemia if not well controlled (Isle, 2001). Many strategies and measures have been taken to combat malaria; rapid diagnosis, treatment, intermittent preventive treatment especially given to pregnant women, use of sulphadoxine- pyrimethamine insecticide treated nets and introduction of sprays and mosquito repellant lotions. All these have been known to reduce morbidity and mortality, but this does not mean that there are no challenges. For instance, if mosquito nets are not used effectively people will still continue to die. For example, the nets may have a hole and used badly, some of the therapies are also facing resistance in some countries. These include Artemisinin combination therapy (ACT) which is facing challenges of resistance in Thailand especially in Cambodian border. Therefore, going back to research more on how to eradicate malaria is very essential. Hence my participation in a clinical trial will not be propagation for new effective and appropriate drugs but to try and convince the researchers to focus on a vaccine and not a drug. Truly, vaccine has worked effectively for so many years’ records, and history has it that the vaccine has a great ability to protect humanity from diseases. Precisely, a vaccine has helped so much in combating smallpox, fighting polio and making the measles and yellow fever very rare (Dziedizc, 2010).. Therefore, vaccine can do so much more for public health, and I have a great conviction that malaria vaccines

Tackling Fraud in NHS of Scotland Essay Example | Topics and Well Written Essays - 1500 words

Tackling Fraud in NHS of Scotland - Essay Example Fraud in NHS Scotland costs an astonishing 100 million a year (Kelbie, 2008). However, NHSScotland Counter Fraud Services (CFS), which was set up as a deterrent safeguard against the further illegal activity, is empowered to discover, examine and trial cases of potential NHS fraud. "It is estimated that 14 million in NHS fraud savings have been made since the agency was established in July 2000." The Crown proudly announced that the NHS savings recouped from the potentially fraudulent activity is equal to the staffing costs of nearly 750 additional nurses or 120 extra consultants. In the alternative, it would fund enough resources for upwards of 2000 hip operation replacements or nearly 100,000 MRI scans, or nearly 200,000 emergency facility attendances (Crown, 2008). In the area of greatest savings, it was determined from two investigations that the greatest annualised cost recoupments were in gold dental inlay fraud reduction and ophthalmic service containment. These two spearheaded and particularized strategic investigations returned more than 2.2m on an annualised basis. The enormity of the savings in just two areas of concern highlights just how pervasive and ubiquitous the problem is (NHS, 2005/2006). The fraudulent activity most rampantly perpetuated involves patients who claim exemption from NHS charges for "dental treatment, optical vouchers and prescription charges; using false identities or fake prescriptions, and using the NHS for treatments free of charge." (Kelbie, 2008).
