Fenofibrate

Bruce R. Brodie, MD

In this study cholesterol levels low to high order fenofibrate uk, Shoudy and collings administered even less ascorbic acid than the marginal levels used by Weaver worst high cholesterol foods safe fenofibrate 160mg. In any further clinical work conducted int his area is there high cholesterol in shrimp generic fenofibrate 160mg mastercard, megascorbic levels of sodium ascorbate should be used ratio van cholesterol purchase discount fenofibrate, Sufficient sodium ascorbate must be available to maintain homeostasis under the sever heat stresses cholesterol test method discount fenofibrate 160mg with mastercard. Agarkov reported in 1962 that 15 milligrams per kilogram of body weight improved the heat resistance of rate (2) cholesterol test home kit purchase 160 mg fenofibrate mastercard. Further studies are required to assess the proper usage of ascorbic acid in heat stress. The use of ascorbic acid in the treatment of severe burns has been neglected, even after Klasson (3) published his dramatic results in 1951. His basic procedures might have eliminated suffering and saved the lives of many fire victims over the past twenty years if it had been more widely used. Klasson reported don sixty-two burn cases from a variety of causes such as hot water, hot grease, gasoline explosions, and chemical agents. When these were applied, there was immediate relief from pain, which permitted a reduction in the morphine given the victims. Spraying the throat or gargling with a 1 percent ascorbic acid in normal saline solution, rapidly alleviated the hoarseness and pain caused by swallowing smoke. In addition, Klasson gave up to 2,000 milligrams of ascorbic acid a day by mouth or intravenously and at "no time were deleterious effects from the drug observed. He summarized his study by stating that ascorbic acid alleviates pain, hastens healing combats the accumulation of toxic protein metabolites in severe burn cases, and reduces the time needed before skin grafting. Klenner (4), in 1971, stated he had found the "secret" for reducing paid and infection form severe burns, preventing toxemia and promoting healing. A 3 percent solution of ascorbic acid is sprayed over the entire burned area every two to four hours for about five days. Vitamin A and D ointment is then alternated with the 3 percent ascorbic acid spray. Megascorbic doses are administered by mouth and by vein of 500 milligrams of ascorbic acid per kilogram body weight as sodium ascorbate (35 gram for a 70-kilogram adult) every eight hours (105 grams a day) for the first several days, then at twelve-hour intervals (1 gram calcium gluconate is given daily to replace calcium lost in body fluids). What more suggestive and promising leads are required to start a program of research to explore a new treatment for burns to replace the rather primitive methods now used Klasson cites fifteen references from the medical literature, dating back to 1936, which lead him to try ascorbic acid. Later work (5) showed the profound influence of burns on the ascorbic acid metabolism, but no group bothered to conduct the large-scale crucial clinical trials using ascorbic acid or 157 sodium ascorbate at megascorbic levels (topically, orally, and intravenously), to develop an improved therapy. Cold There is a considerable medical literature on cold temperatures and their effect on the ascorbic acid in the body. Outstanding are the investigations of the Canadian Dugal and coworkers, starting in 1947, continuing for many years, and summarized in 1961. In their 1947 paper (6), they reported rats, which were exposed for long periods to freezing temperatures,but which were able to adjust to these low temperatures, had large increases in the ascorbic acid levels of their body tissues; whereas, those rats unable to adjust to the cold environment had decreased levels. They concluded that maintenance of life at low temperatures requires large quantities of ascorbic acid. In long-term tests on monkeys reported in 1952, Dugal and Fortier (6) o found that among monkeys exposed for six months to cold temperatures (50 F) o and then subjected to subfreezing temperature (-4 F) those given 325 milligrams of ascorbic acid daily for the six month period were far more resistant to the intense cold than those given only 25 milligrams a day. No tests have been conducted to determine if the resistance of humans to cold temperatures could be improved using 4 grams or more of ascorbic acid. One short-term test (thirteen days) on soldiers, reported in 1954,employed only 525 milligrams of ascorbic acid a day in one group and 25 milligrams in another. The group on the high, but sill marginal levels of 525 milligrams, showed improved resistance to the cold and a large decrease in foot troubles over the 25-milligram group. In another short-term test reported, in 1946, Glickman and coworkers broadly concluded that the results of their experiment indicated clearly that the ability of men to withstand the damaging effects of repeated exposures to cold environments cannot be appreciably enhanced by giving "excessive" doses of ascorbic acid or other vitamins above the amounts required for adequate nutrition. However, their idea of an "excessive" dose of ascorbic acid was 200 milligrams a day, which had been shown to be ineffective in the monkey experiments previously mentioned (6). We cannot say, at this point, whether the megascorbic levels will improve human resistance to cold or not, but if further tests are to be conducted, they should use at least the levels found successful in 158 monkeys. There are millions of people suffering each year from the effects of winter cold who may benefit if these tests yield successful results. Physical Trauma Ungar (7), a member of the Free French Forces studying wound ballistics, provided information of vital importance which might have saved the lives of thousands of soldiers and auto accident victims if it had been properly followed up. The purpose of his study was to relate the degree of trauma expressed in terms of physical energy with the severity of shock as estimated by mortality. Ungar took anesthetized guinea pigs and dropped known weights from different heights onto the animals and found there was a definite relationship between transmitted energy and tissue damage and mortality. The startling fact brought out by his research was that in guinea pigs subjected to the dropped weights, which ordinarily would kill 100 percent of the animals, these animals would always survive if given an injection of ascorbic acid in doses about 100 milligrams per kilogram of body weight shortly after the trauma. His injection dosage calculates to over 7 grams of ascorbic acid, based on a 70-kilogram body weight. The prompt administration of this amount or more of ascorbic acid in the battlefield to wounded soldiers or to auto accident victims at the scene may prevent shock and ensure survival until they reach a hospital. You might well ask how it is possible for such an important observation to lay dormant for 30 years. Bone Fracture the 1946 paper by Andreae and Browne (7) showed that tin man, both burn and bone fracture trauma produce rapid decreases of ascorbic acid in the whole blood and the white blood cells. A 1962 paper from the Soviet Union by Merezhinskii (7) reported tests on guinea pigs with bone fractures. Merezhinskii showed the the daily administration of 40 milligrams of ascorbic acid was sufficient to correct for the ascorbic acid losses due to the trauma but 10 milligrams were not. He found that the recovery from bone fractures was considerably shortened when large doses of ascorbic acid were given. His successful 40-milligram dose, when scaled up to a 150 pound body weight, amounts to the daily intake of about 9 grams of ascorbic acid, while his inadequate 10-milligram dose is equivalent to 2. Severe hypoxia can be induced in the body by means other than high altitude, such as drowning. If people are transported from sea level to high mountainous altitudes, there is a chance that they will develop acute mountain sickness before they become accustomed to the great heights. The disease is called soroche in the Andes and probably has many other local names in various mountain areas. The air we breathe contains about 20 percent oxygen at sea level but only about 15 percent at about 15,000 feet. High altitude was also a problem in aviation before the advent of the pressurized cabin, As long ago as 1938 it was perceived that ascorbic acid increases the altitude tolerance of ski troop and rabbits. Peterson, in 1941, showed that mice injected with ascorbic acid were able to withstand repeated exposure to air pressures that were 1/6 normal, while their untreated companions succumbed. Krasno and coworkers showed in 1950, using human subjects repeatedly exposed to 18,000-foot altitude conditions, increased utilization of ascorbic acid with consequent depletion. This was confirmed in guinea pigs exposed to the same high altitudes, with the animals manifesting abnormally low levels of tissue ascorbic acid. In a 1959 paper from Yugoslavia, Wesley and coworkers reported that in guinea pigs exposed for one hour to low air pressures equivalent to a 30,000-foot height, there was a drop in ascorbic acid levels and a substantial increase in the more toxic dehydroascorbic acid levels. This was also confirmed in dogs; and tests were made on men who responded similarly to the hypoxia, depending upon the intensity and duration of exposure (8). Even with this extensive background of suggestive research, I was unable to find anyone who was inspired to prevent altitude sickness or the bad effects of hypoxia by the administration of high levels of ascorbic acid. The closest to a test of this nature was reported by Brooks (8), in 1948, using the dyestuff, methylene blue. She found that if people who normally suffered from altitude sickness were given 0. Also, untreated subjects who became ill with headache and nausea at 10,000 feet, if given 0,1 gram of methylene blue, were free of the symptoms within an hour. Methylene blue and ascorbic acid a re both members of oxidation-reduction systems and should have similar therapeutic actions. The diuretic effect of ascorbic acid should also help relieve the pulmonary edema that develops at high altitudes. It is time now for the necessary further clinical work, since hypoxia is a widespread problem much beyond altitude sickness. The results obtained would be important in the treatment of the hypoxia of nonfatal drownings, of infants during birth, during anesthesia in surgery, in prolonged surgical procedures, and in suffocation cases, to prevent brain damage. Radiation Exposure to radiation is an extremely stressful situation for the living organism. The term "radiation" includes ultraviolet rays, X rays, gamma rays, and other ionizing radiation in the radiant-energy spectrum. The dangers of exposure to X rays have been recognized in recent years and the radiation casualties of the atom bombings are proof of the hazards. Exposure to radiation, as an occupational hazard for physicians specializing in radiology, has had a life shortening effect and has increased susceptibility to disease, as compared to physicians in other specialties (9). There have been numerous papers published showing that exposure to X rays lowers the levels of ascorbic acid in the body: Kretzschmer et al. In general, these papers indicate that in guinea pigs, which cannot synthesize their own ascorbic acid under stress, there are decreases on ascorbic acid in the blood and tissues after irradiation. Animals, such as rats and rabbits, that produce ascorbic acid in their livers under stress usually suffer an initial drop in their ascorbic acid level which rises after the liver has had a chance to replace the lost ascorbic acid. If the irradiation is severe enough to interfere with the synthesis of ascorbic acid, the losses remain. The use of ascorbic acid as a protection against the unfavorable effects of radiation goes back many years and, in spite of the fact that the investigators used pitifully small doses of ascorbic acid, many reported good results. Carrie and Schnettler, in 1939, using only 200 milligrams a day of ascorbic acid, reported good results and recommended it as the medication of choice. They were able to prevent the leukopenia (reduction of white blood cells in the blood) induced by exposure to X rays. This was confirmed by Clausen, in 1942, who prevented the leukopenia in ten stomach cancer patients treated with X rays by giving them a daily injection of 500 milligrams of ascorbic acid. Wallace, in 1941, injected only 50 milligrams of ascorbic acid daily and was able to report that it prevented many general symptoms of radiation sickness and almost entirely eliminated the severe 161 nausea and vomiting, but it did not prevent the intestinal changes due to the heavy pelvic X-ray treatments administered (11). Kalnins, from Sweden, who published many other papers in this area, reported in 1953 that the X-ray lesions of guinea pigs given 50 milligrams a day of ascorbic acid were much better protected against the damaging radiation effects than those given only 1 milligram a day. He thought that the large doses of ascorbic acid acted as detoxicant for the histamine-like bodies or the leukotoxins developed in the irradiated tissue. Yusipov, from the Soviet Union, in two short papers reporting tests in 1959 on rabbits and rats that did not specify the dosages of ascorbic acid he used, indicated that if ascorbic acid was given before the irradiation, it exerted an unfavorable effect, but if administered afterward it was beneficial. He recommended the use of ascorbic acid in the treatment of acute radiation sickness in the latent period and period of climax. He mentions that the clarification of the role of ascorbic acid in acute radiation sickness is one for the immediate future (11). Several papers have appeared showing the protective effect of ascorbic acid on various bodily enzymes against destruction by ionizing radiation. Although the usefulness of ascorbic acid has been indicated, the crucial clinical tests, using the higher levels of ascorbic acid, have not been initiated. There are, however, some areas which may not fully respond, and a complete elimination of pollutants certainly is not likely in the foreseeable future. One area of pollution is the natural background radiation level due to cosmic and other radiation from the sun and outer space. Even when crowds of people congregate they are irradiating themselves and surrounding people with the rays from the radioactive potassium in their bodies. While a major source of local carbon monoxide buildup in the atmosphere is due to combustion of fuels, (estimated to produce 200 million tons a year), even if this were completely eliminated, there would still be other sources. The air over the oceans and virgin forests, far from human contamination, would thus never be free of a low, but definite, level of carbon monoxide. Measures to lessen direct contamination of the air and soil are being developed, but it may take years for them to take noticeable effect. In the meantime, a supplemental approach to this problem, which is being suggested is to make the population more resistant to the harmful effects of the pollutants by using ascorbic acid. The previous chapters on the effects of ascorbic acid in 163 combating the various chemical and physical stresses suggest a valid basis for this new approach. The daily administration of a few grams of ascorbic acid may be adequate to increase the resistance of the body to these chronic toxic environmental stresses. In the case of carbon monoxide toxicity, a 1962 paper from the Soviet Union (3) showed that the chronic exposure of guinea pigs to carbon monoxide increased the rate of consumption of an requirement for, ascorbic acid. The effects of chronic carbon monoxide poisoning were counteracted by administering 40 milligrams of ascorbic acid daily. For a 300-gram guinea pig, 40 milligrams are equivalent to 9,000 milligrams (9 grams) for a 150-pound body weight. In 1955, Klenner (3) noted that the treatment of choice for carbon monoxide poisoning, both acute and chronic, was ascorbic acid. Two other papers need to be mentioned in this discussion, one appearing as far back as 1930 and the other in 1958. Ungar and Bolgert (4) showed that ascorbic acid would protect guinea pigs against death from exposure to high concentrations of hydrochloric acid vapor, nitric oxide, and other vapors. To be effective, however, it was necessary to give not less than 500 milligrams per kilogram of body weight, which is equivalent to about 35,000 milligrams for a 150-pound body weight. Ozone, a necessary constituent of the upper atmosphere and a contaminant produced in the air we breathe under certain conditions, is a toxic oxidizing substance. Mittler (4), in 1958, reported that a single injection of ascorbic acid into mice before exposing them, for 3 hours, to air containing an ozone level of 8 to 25 parts per million, provided a higher rate of survival than among untreated mice. Will the agencies now so concerned with our external environment also be concerned with our individual internal environment and implement research on the use of ascorbic acid to combat environmental hazards With all the furor about cleaning up the air we breathe, smokers nonchalantly inhale the concentrated smoke from a plug of burning tobacco an inch or two from their face.

Previous meta analyses have determined that the evidence is controversial, the current data is not persuasive, and the field is too current. Specifically, this paper analyzes author affiliation, grant and funding information, and correlation results to see if a bias currently exists among these studies. This paper is different from previous studies because the information is current, the variables are grouped and measured differently, and both affiliation and funding information is provided. After a qualitative and quantitative review of the current research, there appears to be a relationship between the place of funding or author affiliation of a study and whether or not the author(s) find a correlation between cell phones and cancer. This relationship means that there is a significant possibility that bias exists in the results of these studies. Key Words: cell phones, electromagnetic radiation, cancer, health, public policy Author Notes: There are no conflicts of interest, and the author did not receive any funding for this paper. This abstract was provided by the author, and the work and viewpoints expressed in this paper is solely that of the author. Furthermore, this paper analyzes author affiliation, grant and funding status, and results to see if a bias currently exists among studies. Introduction and Background Background In 1865, James Clerk Maxwell proposed and published the theory of electromagnetic radiation (Columbia Encyclopedia, 2008). Electromagnetic radiation is energy radiated in the form of a wave as a result of the motion of electric charges (2008). If the motion of a magnetic field changes or accelerates, the magnetic field can provide an electric field (2008). The produced electromagnetic wave is both a transverse and a polarized wave (2008). More importantly, electromagnetic radiation does not require a material medium and can travel through a vacuum (2008). Mobile phone use has greatly expanded both domestically and internationally in recent years. Census Bureaus latest Statistical Abstract Report in 2004, cell phone use in the United States has increased by 300 percent since 1995. However, in 2004, the number of Americans that had a cell phone subscription approached 159 million (2004). The report predicts that Africa will have the highest rate of growth and will add 265 million new mobile subscribers over the next 6 years (2006). Kundi writes, Because of the enormous increase in mobile phone use starting in the mid-1990s and reaching almost 100% prevalence in many countries worldwide by now, concerns have been raised that even small risks for developing chronic diseases such as cancer from mobile phone use may have substantial impact on public health (p. Since that study, scientists, doctors, and other professionals have issued dozens of reports and peer-reviewed journal articles that prove either a correlation between cell phones and cancer exists or does not prove that correlation exists. These reports are paid for privately, through a university or hospital, or by grants. One must be cognizant of the source of funding when reviewing the results of such studies. As of today, there is increasing concern in the fields of medicine, public health, policy, and law about this issue. Researchers must also review author affiliation, grant and funding status, and results to see if a bias in these studies exists and influences the results. If a bias does exist, governments and other organizations must be willing to regulate and oversee the groups funding and performing these biased studies. Previous Meta-analyses There have been a few meta-analyses to determine the strength of the correlation between cell phones and cancer. To date, evidence has not shown a definitive correlation between cell phones and cancer. Meta-analyses have concluded that the information is controversial, the data is not persuasive, and the field is too new. This technology is constantly changing and there is a need for continued research on this issue (2005, p. Roosli states that there is little evidence that short-term exposure to a mobile phone or base station cause ill-health or other symptoms (2008, p. Meta-analyses show that the current data is controversial, and researchers must continue to review the correlation as the field advances. The study collected information from 13 countries: Australia, Canada, Denmark, Finland, France, Germany, Israel, Italy, Japan, New Zealand, Norway, Sweden, and the United Kingdom (2007). The study included 7,658 controls and results demonstrated 2,765 cases of glioma, 2,425 cases of meningioma, 1,121 cases of acoustic neurinoma, 109 cases of malignant parotid gland tumour (2007). As of today, some studies have not been completed and are still being investigated. The authors found that out of 59 studies, 12 (20%) were funded exclusively by the telecommunications industry, 11 (19%) were funded by public agencies or charities, 14 (24%) had mixed funding (including industry), and in 22 (37%) the source of funding was not reported (2007). The authors cited that the telecommunications industry documented the highest outcome number; however, the telecommunications industry were least likely to report statistically significant results: the odds ratio was 0. The authors conclude, The interpretation of results from studies of health effects of radiofrequency radiation should take sponsorship into account (2007). Methodology Types of Cancer the types of cancers this paper reviews for correlation and funding information include the following: acoustic neuroma, testicular cancer, glioma, and meningioma. Acoustic neuroma is a nonmalignant usually slow growing tumor involving the Schwann cells of a vestibular nerve that may cause deafness, tinnitus, and disturbance of the sense of balance and may be life threatening if not treated (2010). Finally, meningioma is a slow-growing encapsulated tumor arising from the meninges and often causing damage by pressing upon the brain and adjacent parts (2010). Data Collection A triangulation approach was used to review and present the materials. The author searched the Academic Search Complete online database from the University Libraries at the George Mason University School of Public Policy on two separate dates: March 3, 2010 and March 10, 2010. Only relevant materials from peer-reviewed journal articles, memos in peer-reviewed journals, or magazines were selected. Newspaper articles and summary articles from peer-reviewed journals in magazines were not selected. For example, if a previous article discussed a past journal article or website, that article or website would be pulled and reviewed. After an exhaustive review of material, 50 total relevant information sources remained. Once each abstract and article was reviewed for relevancy, the total articles from these databases were added to a comprehensive spreadsheet (Appendix A). Appendix A includes the following categories: title, year, type, author, author affiliation, result (yes, no, or inconclusive), funding type, and notes. The title, year, and author sections refer to the title, year, and author(s) of the article. The type section includes peer-reviewed journal articles, memos in peer-reviewed journal articles, magazine articles, and websites. The results section summarizes if the author(s) found a correlation between cell phones and cancer. Statistical Analysis Information from these correlation studies were collected and analyzed. This variable measures by whom the study was funded or with whom the author was affiliated. This variable measures if the study finds a correlation between cell phone use and cancer. This variable has the following attributes: 1 = No; 0 = Inconclusive and 1 = Yes. This study is different from previous studies because the information is current, the variables are grouped and measured differently, and both affiliation and funding information is provided. Results First, the tab command was run to obtain information about each variable. Out of those 50 articles, 14 found a correlation between cell phones and cancer, 21 found no correlation, and 15 were inconclusive. Out of the 11 studies, the government found nine studies with no correlation and two with an inconclusive correlation. Out of the seven studies, the mobile phone companies found six studies with no correlation and one study with a correlation. Out of the 18 studies, this group found 12 studies with a correlation, one study with no correlation, and five studies with an inconclusive correlation. Finally, the category other, which includes magazines and businesses, funded or were affiliated with 14 studies. Out of the 14 studies, this group found one study with a correlation, five with no correlation, and eight with an inconclusive correlation. Some interesting findings in this cross-tab include: the government found no correlation in 81. There appears to be a significant discrepancy between the author affiliation and the final correlation result between cell phones and cancer. Next, a bar graph was created comparing the mean score of correlation by author affiliation (Figure 1). Bar Graph of Cancer Correlation by Author Affiliation this graph shows that studies funded by or affiliated with either the government or mobile companies are more closely aligned to not finding a correlation between cancer and cell phones. Finally, the graph shows that studies funded by or affiliated with the other category, such as magazines or businesses, are more closely aligned to finding an inconclusive correlation between cancer and cell phones. The Chi square test is a quantitative measure used to determine whether a relationship exists between two categorical variables (Berman, 2007, p. This paper attempts to identify a statistically significant finding between the variables affiliation and correlation and between year and correlation. There is a statistically significant relationship between the author affiliation and whether or not there is a! This means that the funding or author affiliation for a specific study has a relationship with whether or not the author(s) find a correlation between cell phones and cancer. The alternative hypothesis is that a relationship exists between these two variables. There is not a statistically significant relationship between the year the article was published and whether or not there is a correlation between cell phones and cancer. This means that the year the study was published has no relationship with whether or not the author(s) find a correlation between cell phones and cancer. The null hypothesis is that the population means are the same between these two variables. The alternative hypothesis is that population means are not the same between these two variables. The population means do not appear to be the same between the year the article was published and whether or not there is a correlation between cell phones and cancer. Discussion Mobile Phone Companies the mobile phone companies funded or were affiliated with seven total studies, six of which were not correlated to finding that cell phones cause cancer. Mobile phone companies monitor the results of cell phones and cancer studies carefully. To date, no large mobile phone company has acknowledged any correlation between mobile phones and cancer. Out of the 11 studies government funded, researchers found nine studies with no correlation and two with an inconclusive correlation. None of these government organizations found a significant association between cell phones and cancer. They continue, While some experimental data have suggested a possible link between exposure and tumor formation in animals exposed under certain specific conditions, the results have not been independently replicated, and other studies have failed to find evidence for a link to cancer or any related condition (2010). Cellular phone radiation occurs in both the radio and microwaves frequency (Ketcham, 2010). The goal of the program is to increase business competition, increase wireless technology use, and decrease the cost of this technology. Other Organizations Other organizations also weigh in on the debate between cancer and cell phone use. This group found one study with a correlation, five with no correlation, and eight with an inconclusive correlation. These other organizations fund studies, report findings, and even develop investigative branches regarding! Any member state or agency within a state is able to participate in this program, and the states fund the program themselves (2010). These limitations to previous studies include an insufficient length to the studies, a lack of focus on outcomes related to children, and rough measurements of cell phone use (2010). Hospitals and Universities Hospitals and universities are affiliated with or have funded 18 studies, of which 12 found a correlation. This is the largest group to find a significant correlation between cell phones and cancer. Hospitals and universities encompass the last main group of organizations that report on the relationship between cell phones and cancer. There are many hospitals and universities that report on this matter, and studies have been growing each year as more information is accumulated.

This is especially true when it can be shown that the crash forces in a fatal aircraft accident should have been survivable list of best cholesterol lowering foods buy fenofibrate without prescription. Possi ble design corrections then can be addressed, and short-term alterations can be made to improve crash survivability. Crash Survivability this chapter presents survivability principles and describes procedures for calculating crash forces. While the calculations more frequently fit aircraft without ejection seats, they are not restricted to such aircraft. The investigation of injuries and deaths from crashes which can be shown to have been survivable will identify problems such as weak seat-to-floor tiedowns, noncrashworthy fuel systems, helmets that offer marginal head injury protection or that may themselves cause lethal injuries, and rudder pedals that fracture tibia and 24-1 U. For too long it has been assumed that injuries or fatalities naturally occur in acci dent sequences. The Components of Survivability Survivability requires two things: the presence of tolerable deceleration forces and the maintenance of a volume of space consistent with life. This section highlights the mathematics of crash force calculations and considers the elemental components of survivability. Using known speed, stopping distances, and gravity constants, it is relatively simple to calculate the deceleration forces imposed on an airframe. These numbers must then be viewed from the perspective of the aircrewman for whom other factors serve to increase or decrease the acceleration (G) forces he must tolerate to survive. An airframe which disintegrates, allows penetration by objects, or which fails to otherwise preserve an appropriate volume of living space can produce or contribute to injuries. The use in larger airframes of brittle alloys that trade off pressurization integrity for impact resistance has been a source of container problems. Another obvious example is the invasion of the aircrew living space by helicopter transmissions after the main rotor blades strike the ground. The limited space between crew seats and controls, dashboards, or outside objects with which the crew can collide is also a container problem. The thoughtful investigator will evaluate the living space remaining after impact forces have been dissipated, remembering that some ductile metals can rebound after they have compromised volume, leaving few traces of their brief invasion into the aircrew compartment. To secure an aircrewman with a system of straps designed to withstand a 10,000 pound load is futile unless the system is maintained and used properly. Worn or damaged 24-2 Aircraft Accident Survivability straps may fail at reduced loading. Loosely secured restraints present a special problem because of dynamic overshoot. This occurs when the aircraft has begun deceleration over the time before the crewman actually impinges on his straps, which may either fail or rebound. Crash force calculations under the latter circumstances will be in error by at least a factor of two. Ten thousand pound test straps affixed to a seat which in turn will separate from the floor with a 4 G deceleration in the x-axis, or a 1. Loose restraints invite submarining in which the aircrewman can exit the seat in whole or in part without unfastening the restraint buckle. Buckles that open under survivable decelera tion forces or that cannot be opened with one hand must be identified. Those buckles that cannot be opened if suspended, inverted, or that are so complex as to defy quick opening by nonair crewman must also be eliminated from the inventory. Inertial reels left unlocked may lock automatically as advertised, but only if the deceleration is in the x-axis, and then only after some amount of travel that equates with dynamic overshoot. The aft-facing seat, which ostensibly requires a simpler restraint system, must withstand higher G-loading than its forward-facing counterpart because its center of gravity is higher. A seat designed as forward-facing which is installed facing aft will predictably fail under minor G-loads. The side-facing seat exposes its occupant to the least survivable G-loads, restraining systems not withstanding. There are many features of the cockpit environment which affect the ability of an aviator to withstand crash forces. Pyrolyzation products from fires involving electrical in sulation and polyurethane sound-attenuating or decorative panels can produce inflight in capacitation which reduces survival chances. The same is true for the volatile hydrocarbons pre sent in a cockpit fire at low ambient pressures, with or without the presence of an open flame. The toxicological properties of substances in a sea level environment may be substantially altered when the event occurs at altitude. Another environmental factor which influences crash survivability is the speed with which emergency egress can be accomplished. If an aircrewman or a nonaircrewman has been trained in specific emergency exit procedures, and he is then confronted with unanticipated impediments to a fast exit, survival chances decrease. The capability of a crewman to egress rapidly must be con sidered in assessing survivability. The more energy absorption that occurs in the airframe before the air crewmans body becomes the absorber, the safer the crewman. Honeycomb construction, strok ing seats, and expendable space and metal are a few of the techniques available to the engineer for 24-3 U. Landing gears that can absorb a sink rate of 35 feet per second are expen sive, but they are a reality and will increase the chances for survival. It is only necessary that energy absorption devices be built to absorb a portion of impact in a 40 G crash; man can normally handle the remaining 20. Statistically, the single most important postcrash factor affecting sur vivability is fire. It is a safe assumption that if fire is not yet present at an accident scene, it will be shortly. The atomization of fuels that occurs simultaneously with destructive impact renders all aviation fuels of equally dangerous potential, regardless of flash points, vapor pressures, or other laboratory-measured properties. Army has led the way in the evolution of crashworthy fuel systems designed to prevent spillage or atomization. These breakaway, fail-save valves, pipe connections, and tanks, which all prevent escape of fuel, have dramatically changed the previous ly grim statistics of helicopter postcrash fires. The continued acceptance of belly fuel tanks located beneath or directly adjacent to crew and passenger compartments, where impact and abrasive forces must compromise these spaces, no longer merits tolerance. Along with the direct thermal effects of fire, the attendant hazards from products of combus tion must be recognized. Toxic gases, including carbon monoxide, cyanide, phosgene, and acrolein may all contribute to the injury or be fatal themselves. Particulate matter and smoke can not only interfere with breathing, but also decrease visibility, hindering egress and rescue efforts. Use of thermal protective garments and readiness of firefighting equipment both in the aircraft and at the duty runway edge are standard procedures in the military. These measures are substan tially less effective, however, than the designing of an airframe to absorb impact without fuel spillage and subsequent ignition. A survivable crash, with mild to moderate G-forces that pro duce associated limb fractures in passengers and crew, rapidly becomes a tragedy when postcrash fire occurs and timely egress becomes impossible. Others, such as poor communications, inadequate rescue capabilities, water survival re quirements, and training problems should be evident to the investigator as problems that may re quire corrective action on a local level. These numbers are imperfect because of the indirect methods available for their establishment. As pointed out above, calculations of G-forces imposed on the airframe may bear only limited similarity to the forces imposed on crew and passengers. In using these numbers, it is important to appreciate that as the time of exposure to high-impact forces increases, the tolerance level decreases. For deceleration, duration of the forces and the rate of onset can significantly alter human response. The body acts like porcelain in short duration exposures with a high rate of onset, but like a hydraulic system in longer exposures with a high rate of onset.

Naval Flight Surgeons Manual Table 24-2 Regional Impact Forces Known to Cause Bone Fracture or Concussion Body Area Force Duration Head (frontal bone, 180 G 0. Where the crash forces are not clearly in the x-, y-, or z-axes, it may be appropriate for an in vestigator to solve for the vector most nearly approaching the actual crash force vector and ex trapolate to the likely survivability limits and exposures. Table 24-1 does not present a maximum, or even an average, for survivable crash forces. It does show that level of force which is known to be safe, and beyond which body damage could reasonably be expected to occur. These limits presuppose proper utilization of a four or five-point restraint system by a healthy subject. The limits shown in Tables 24-1 and 24-2 are not so fixed that to exceed them is automatically equated with nonsurvivability. It is also not valid to extrapolate from these limits directly to the G-forces calculated for a given crash situation. When a decision on the survivability of a given situation must be made, the following considerations may be helpful. If the calculated crash forces on the airframe exceed the human tolerance limits by a factor of two or more, survivability 24-6 Aircraft Accident Survivability is unlikely. Survivability Calculations the investigating flight surgeon or physiologist is not expected to be an engineer, a maintenance officer, or qualified in the type of aircraft involved in a mishap. Rather, he must use the talents of the other members of the Aircraft Mishap Board and the consultative expertise available to him, to get the data needed for his calculations. Members of the accident investiga tion team can supply the following information: 1. Vertical stopping distances, measured in feet, including depth of gouges in the earth, depth of water entry before stop, depth of damage to the underside of the aircraft or extent of compres sion of energy-attenuation devices, such as oleo struts and stroking seats. Horizontal stopping distances, measured in feet, including length of gouges in the earth, length of airframe compression in the horizontal plane, backward displacement of each wing, empennage surfaces, engine, and fuselage, or actual stopping distance after water entry. The shape of the deceleration pulse which most nearly reflects the buildup and dissipation of stopping forces. In cases where the Aircraft Mishap Board cannot establish values, the members must estimate a range for the values and make maximum and minimum estimates. Where the range crosses the ex pected limits of survivability, it may have to be narrowed. For example, if the board concludes that the aircraft was traveling between 80 and 100 knots just prior to impact, and it can be shown that 92 knots is the outside limit of the survivability envelope, it may be necessary to reevaluate the evidence so that a more precise airspeed estimate can be obtained. Velocity measurements are extremely important because they are squared in the numerators of the survivability equations (Appendix 24-B) and can considerably magnify any errors. Stopping distances that may be relatively short, appearing in equation denominators, similarly need preci sion and, where possible, should be measured rather than estimated. For convenience, an elec tronic calculator is recommended to perform the actual mathematics involved, remembering that precision beyond the first decimal place is unrealistic. Naval Flight Surgeons Manual Trigonometry Use of basic trigonometric functions (Appendix 24-A) is necessary to establishing force vectors. A brief review of terminology and useful principles of trigonometry follows: Hypotenuse. A fraction using the opposite side dimension as the numerator and the hypotenuse dimension as the denominator. A fraction using the adjacent side dimension as the numerator and the hypotenuse dimension as the denominator. A fraction using the opposite side dimension as the numerator and the adjacent side dimension as the denominator. In a right triangle, the square of the hypotenuse is equal to the 2 2 2 sum of the squares of the other two sides (a + b = c). The basic use of trigonometric relationships in establishing the parameters describing an air craft crash is illustrated in Figure 24-1. If the dimensions of any two sides of the triangle or of one side and the impact angle can be obtained by actual measurement, the other parameters can be calculated. Deceleration Pulses the Aircraft Mishap Board should identify the most likely deceleration pulse shape. The decay or increase of the deceleration forces during the time of application must be represented diagramatically. The various kinds of pulses and the corresponding deceleration equations are il lustrated in Appendix 24-B. There are two groups of formulae: the first is used when the final velocity, (V) is zero and the second when V is not zero. Rectangular Pulse requires unchanging G-forces over the period beginning with the initial velocity and ending with the final velocity. Triangular Pulses require constantly changing deceleration levels, either increasing, decreasing, or a combination of both. An example of a constantly decreasing force is impact against an object that gradually gives way like a tree top. A combination of increasing and decreasing forces would be expected as an aircraft flew through trees or brush.
