Reardon and published by . This book was released on 1996-12-01 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study evaluated the effects of the four combinations of unencumbered MOPPO aviator battle dress uniform (ABDU) and encumbered MOPP4 over ABDU flight ensembles in cool (70 degrees F, 50 percent relative humidity (RH)) and hot (100 degrees F, 50 percent RH) UH-60 cockpit conditions. This report describes the physiological and psychological responses. The most striking, operationally relevant result was that none of the crews in the encumbered MOPP4 hot condition were able to complete the first two 2-hour sorties movements. The results of this evaluation suggest that future rotary-wing aviator flight uniform components should be designed to be lighter weight and allow greater evaporation of sweat. Methods should be sought to improve fit and comfort, particularly for the mask and helmet combination, as well as prevent pressure discomfort over the back due to the life raft. The 11.7 lb ballistic protective plate also should be lighter weight and reduced in thickness. Forced dry air microclimate cooling into the ensemble should be considered for reducing heat accumulation in the encumbered MOPP4 aviator ensemble by enhancing evaporative cooling and thereby increasing endurance times during hot weather operations.

Download or read book Resource Utilization and Development written by Shri Kamal Sharma and published by Northern Book Centre. This book was released on 1992 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: The relationship between resources and development is the pivot around which the present study revolves. Focussing on the process of resource creation and utilization it emphasizes the need of equitable development integrating local needs, resources, people and functions. The resource exploitation and their utilization are two independent economic activities influenced by different algorithms and usually have manifested in core-periphery relationship. Reviews the persistent problems of economic development in perspective of exploitation of natural resources with the objective to provide some clues for occurrence and persistence of regional disparities and for suggesting a development model synchronising both the resource management and environmental protection.

Download or read book Psychological Effects of Chemical Defense Ensemble Imposed Heat Stress on Army Aviators written by and published by . This book was released on 1982 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Psychological testing was conducted with six Army aviators before and after flights in a UH-1H helicopter while wearing standard flight suits, US or UK aircrew chemical defense ensembles. Additional testing on non-flight days was conducted to provide a baseline for evaluation. Tests consisted of encode/decode problems, math problems, logical reasoning problems, target detection problems, and a four-choice reaction time test. Tests were scored for number of attempted, percent correct, reaction time of correct and incorrect responses. Self reports of mood were also taken and scored. The results of the study indicated that various levels of ensemble-imposed heat stress caused orderly changes in psychological function and extended the results of laboratory investigations to the aviation setting. In addition, reaction time data showed changes in the pilot's ability to deal with 'error' situations as a function of imposed heat stress and that self reports of mood were unreliable indicators of severe heat stress.
Book Synopsis Effects of Microclimate Cooling on Physiology and Performance While Flying the UH-60 Helicopter Simulator in NBC Conditions in a Controlled Heat Environment by :
Download or read book Effects of Microclimate Cooling on Physiology and Performance While Flying the UH-60 Helicopter Simulator in NBC Conditions in a Controlled Heat Environment written by and published by . This book was released on 1992 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of microclimate cooling on aviator performance and physiology in nuclear, biological, and chemical (NBC) individual protective equipment (IPE) were evaluated in the USAARL UH-60 research flight simulator. Sixteen male aviators flew the simulator in two temperature conditions, 95 deg F and 105 deg F, both at 50 percent relative humidity (RH). Two thermoelectric conditioning units were used, one providing cooled blown air, the other cooled water to the aviators. At each temperature, they flew for up to 6 hours in NBC IPE with no cooling, air cooling, and liquid cooling. There was an extra condition at 105 deg F when vent air with no cooling was blown through the air vest, making a total of seven test conditions. There were significant improvements in flight performance as a result of the cooling, more so at the higher temperature. Also, there were differences between the two cooling systems at 105 deg F, with the air system producing significantly lower flight error rates. Survival time was based on the length of time each subject stayed in the condition before reaching physiological withdrawal criteria (rectal temperature of 39 deg C or heart rate of 150 beats per minute for 15 minutes) or exercising their option to retire early. There were considerable increases in survival time with the use of microclimate cooling. The mean survival time at 95 deg F was increased to 385 minutes with the liquid system from 285 minutes without cooling. At 105 deg F to 333 minutes for the air system from 79 minutes with no cooling, the improvement was even more dramatic. There were significant differences between the two cooling systems at 105 deg F with the air system producing longer survival times.
Book Synopsis Heat Stress Evaluation of Special Operations Aviation Regiment and Air Warrior Concept 1 and 3 Aviator Ensembles in a UH-60 Simulator by : Matthew Reardon
Download or read book Heat Stress Evaluation of Special Operations Aviation Regiment and Air Warrior Concept 1 and 3 Aviator Ensembles in a UH-60 Simulator written by Matthew Reardon and published by . This book was released on 1999-03-01 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: This aviator heat stress study used a mixed between/within test subject design with one environmental condition (hot) and three rotary-wing MOPP4 ensembles (Special Operations Aviation Regiment SOAR), Air Warrior Concept 1, and Air Warrior Concept 3) encumbered with ballistic protection and over- water survival components. The SOAR ensemble was tested with (SC) and without (SX) microclimate cooling (MCC) consisting of a water-cooled undershirt with portable refrigerator/pump. Air Warrior Concept 1 and Concept 3 aviator MOPP4 ensembles were tested with (AC) and without (AX) MCC, respectively. Physiological and subjective data were obtained to compare thermoregulatory responses and quantitate the benefits of microclimate cooling. Test sessions consisted of a 20-minute treadmill walk in a heated (100 deg F and 20 percent relative humidity RH) environmental chamber to stimulate outdoor preflight activities, followed by three 2-hour sorties in a research UH-60 simulator with cockpit conditions set at 1000F and 50 percent RH (90 deg F wet-bulb globe temperature WBGT).
Book Synopsis Effects of Physiologic Heat Stress on Cognitive Performance During Simulated Flight Tasks by :
Download or read book Effects of Physiologic Heat Stress on Cognitive Performance During Simulated Flight Tasks written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is known that heat stress leads to reduced +Gz-tolerance in tactical aircrew. The first phase of an effort to determine the relationship between physiologic heat stress and flight performance was conducted using the new NAWCADPAX flight simulator installed in an environmental chamber. Performance scores declined after subjects were exposed to the hot alert conditions relative to control, though the difference was not statistically significant. Correlation analysis indicated a marginal relationship between the change in performance and rectal and mean skin temperatures (r = 0.59 and 0.55, respectively). The experimental design did not account for the increased generation of metabolic heat associated with straining against high G forces, though it did include radiant heat loads. The next phase will include physical work in the cockpit to account for this additional factor.

Book Synopsis The Effects of 37 Hours of Continuous Wakefulness on the Physiological Arousal, Cognitive Performance, Self-Reported Mood, and Simulator Flight Performance of F-117A Pilots by :
Download or read book The Effects of 37 Hours of Continuous Wakefulness on the Physiological Arousal, Cognitive Performance, Self-Reported Mood, and Simulator Flight Performance of F-117A Pilots written by and published by . This book was released on 2003 with total page 83 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 30 years, fatigue has contributed to a number of Air Force mishaps. Resource cutbacks combined with increased operational tempos, sustained operations, and night fighting could exacerbate the problem. Extended wakefulness and circadian factors can be especially problematic in military aviation where mission demands sometimes necessitate flights as long as 17-44 hours. To effectively counter fatigue in such operations, the effects of this threat must be objectively measured and understood. This study assessed F-117A pilots during a 37-hour period of continuous wakefulness. Although none of the pilots crashed, substantial decrements were found in flight-skills, reaction times, mood, and brain activation as early as after the 26% hour of continuous wakefulness. The greatest flight degradations occurred after 27-33 hours awake, even though many pilots believed their worst performance was earlier. The decrements found in this relatively-benign test environment may be more serious under operational conditions unless personnel anticipate the most dangerous times and administer valid fatigue countermeasures.

Book excerpt: From the New York Times bestselling author of Little Brother, Cory Doctorow, comes Pirate Cinema, a new tale of a brilliant hacker runaway who finds himself standing up to tyranny. Trent McCauley is sixteen, brilliant, and obsessed with one thing: making movies on his computer by reassembling footage from popular films he downloads from the net. In the dystopian near-future Britain where Trent is growing up, this is more illegal than ever; the punishment for being caught three times is that your entire household's access to the internet is cut off for a year, with no appeal. Trent's too clever for that too happen. Except it does, and it nearly destroys his family. Shamed and shattered, Trent runs away to London, where he slowly learns the ways of staying alive on the streets. This brings him in touch with a demimonde of artists and activists who are trying to fight a new bill that will criminalize even more harmless internet creativity, making felons of millions of British citizens at a stroke. Things look bad. Parliament is in power of a few wealthy media conglomerates. But the powers-that-be haven't entirely reckoned with the power of a gripping movie to change people's minds....

Book Synopsis The Hunt for Zero Point by : Nick Cook
Download or read book The Hunt for Zero Point written by Nick Cook and published by Crown. This book was released on 2007-12-18 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This riveting work of investigative reporting and history exposes classified government projects to build gravity-defying aircraft--which have an uncanny resemblance to flying saucers. The atomic bomb was not the only project to occupy government scientists in the 1940s. Antigravity technology, originally spearheaded by scientists in Nazi Germany, was another high priority, one that still may be in effect today. Now for the first time, a reporter with an unprecedented access to key sources in the intelligence and military communities reveals suppressed evidence that tells the story of a quest for a discovery that could prove as powerful as the A-bomb. The Hunt for Zero Point explores the scientific speculation that a "zero point" of gravity exists in the universe and can be replicated here on Earth. The pressure to be the first nation to harness gravity is immense, as it means having the ability to build military planes of unlimited speed and range, along with the most deadly weaponry the world has ever seen. The ideal shape for a gravity-defying vehicle happens to be a perfect disk, making antigravity tests a possible explanation for the numerous UFO sightings of the past 50 years. Chronicling the origins of antigravity research in the world's most advanced research facility, which was operated by the Third Reich during World War II, The Hunt for Zero Point traces U.S. involvement in the project, beginning with the recruitment of former Nazi scientists after the war. Drawn from interviews with those involved with the research and who visited labs in Europe and the United States, The Hunt for Zero Point journeys to the heart of the twentieth century's most puzzling unexplained phenomena.
Book Synopsis Lana and Lilly Wachowski by : Cael M. Keegan
Download or read book Lana and Lilly Wachowski written by Cael M. Keegan and published by University of Illinois Press. This book was released on 2018-11-15 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lana and Lilly Wachowski have redefined the technically and topically possible while joyfully defying audience expectations. Visionary films like The Matrix trilogy and Cloud Atlas have made them the world's most influential transgender media producers, and their coming out retroactively put trans* aesthetics at the very center of popular American culture. Cáel M. Keegan views the Wachowskis' films as an approach to trans* experience that maps a transgender journey and the promise we might learn "to sense beyond the limits of the given world." Keegan reveals how the filmmakers take up the relationship between identity and coding (be it computers or genes), inheritance and belonging, and how transgender becoming connects to a utopian vision of a post-racial order. Along the way, he theorizes a trans* aesthetic that explores the plasticity of cinema to create new social worlds, new temporalities, and new sensory inputs and outputs. Film comes to disrupt, rearrange, and evolve the cinematic exchange with the senses in the same manner that trans* disrupts, rearranges, and evolves discrete genders and sexes.
