Available in PDF, EPUB and Kindle. Book excerpt: Evaporation is a phase change process with potential for achieving large heat transfer rates under high air temperatures due to the latent heat of vaporization. Bioin-spired artificial perspiration systems can leverage the evaporation of sessile droplets to implement this effect for different cooling applications. In the case of human perspiration, droplet evaporation typically occurs under exposure to moving air, or forced convection. However, current approaches to understanding droplet evaporation primarily use a vapour-diffusion limited model. Experiments using an open-loop wind tunnel and computer-vision based control system were conducted to measure evaporation rates of continuously-fed sessile droplets under forced convection. Results demonstrated increases to the evaporation rate with the inclusion of forced convection and removal of the vapour-diffusion limit, but also shows evidence for a limit based on thermal behavior. Additional experiments also demonstrate boundary layer effects caused by adjacent droplets suppresses increases to the evaporation rates from forced convection.

This book was released on 2021-07-13 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: A New York Times Most Anticipated Book of the Summer A taboo-busting romp through the shame, stink, and strange science of sweating. Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat, Sarah Everts delves into its role in the body—and in human history. Why is sweat salty? Why do we sweat when stressed? Why do some people produce colorful sweat? And should you worry about Big Brother tracking the hundreds of molecules that leak out in your sweat—not just the stinky ones or alleged pheromones—but the ones that reveal secrets about your health and vices? Everts’s entertaining investigation takes readers around the world—from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. In Finland, Everts explores the delights of the legendary smoke sauna and the purported health benefits of good sweat, while in the Netherlands she slips into the sauna theater scene, replete with costumes, special effects, and towel dancing. Along the way, Everts traces humanity’s long quest to control sweat, culminating in the multibillion-dollar industry for deodorants and antiperspirants. And she shows that while sweating can be annoying, our sophisticated temperature control strategy is one of humanity’s most powerful biological traits. Deeply researched and written with great zest, The Joy of Sweat is a fresh take on a gross but engrossing fact of human life.
Download or read book Nutritional Needs in Cold and High Altitude Environments written by Committee on Military Nutrition Research and published by National Academies Press. This book was released on 1996-05-29 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the research pertaining to nutrient requirements for working in cold or in high-altitude environments and states recommendations regarding the application of this information to military operational rations. It addresses whether, aside from increased energy demands, cold or high-altitude environments elicit an increased demand or requirement for specific nutrients, and whether performance in cold or high-altitude environments can be enhanced by the provision of increased amounts of specific nutrients.

Available in PDF, EPUB and Kindle. Book excerpt: Research into perspiration has developed dramatically during the last 15 years, continually improving our understanding of the pathogenesis of sweating disorders. It has become clear that, in addition to its temperature-regulating function, perspiration offers bactericidal protection as well. In this book, select authors further broaden our perspective on perspiration. Contributions cover a variety of new aspects, offering insight into the sweat glands' major role during the onset of disorders such as parapsoriasis, lichen planus, and lichen amyloidosis. They also highlight the importance of Malassezia - an allergen in sweat that exacerbates atopic dermatitis and cholinergic urticarial. Further roles of the sweat glands are discussed, including as storage of stem cells for replenishing epidermal cells in the case of thermal burns or as water retention sites for replenishing moisture in the stratum corneum. In addition, a novel analysis of the sweat glands' three-dimensional structures, using high-speed en-face optical coherence tomography (OCT), is introduced. Offering an in-depth overview of the latest knowledge in perspiration research, this book serves as an essential reference for all medical staff and researchers in the field.

Available in PDF, EPUB and Kindle. Book excerpt: Air conditioning boosts man's efficiency no less than his comfort. Air-conditioned homes, offices, and factories unmistakably raise human productivity and reduce absenteeism, turnover, mistakes, accidents and grievances, especially in summer. Accordingly, many employers every year cool workrooms and offices to raise summer profits. Employees in turn find cool homes enhancing not only comfort and prestige but also personal efficiency and income. With such economic impetus, low-cost summer cooling must irresistibly spread to all kinds of occupied buildings. Refrigeration provides our best cooling, serving well where people are closely spaced in well-constructed, shaded, and insulated structures. However, its first and operating costs bar it from our hottest commercial, industrial, and residential buildings. Fortunately, evaporative cooling is an economical substitute in many regions. First used in Southwest homes and businesses and in textile mills, it soon invaded other fields and climates. In 1946, six firms produced 200,000 evaporative coolers; in 1958, 25 firms produced 1,250,000, despite the phenomenal sale of refrigerating window air conditioners. Though clearly secondary to refrigeration, evaporative cooling is 60 to 80 percent is economical for moderate income groups and cheaper to buy and operate. Thus, it climates where summers are short. Moreover, it cheaply cools hot, thinly constructed mills, factories, workshops, foundries, powerhouses, farm buildings, canneries, etc., where refrigerated cooling is prohibitively expensive.
