Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This book is intended to provide the information regarding development and comparative study of headgear for male farm workers under heat stress condition. To minimize heat stress in warm climate many techniques are used. One of them is the use of headgear which protects the head. Farmers are using towel, pagdi, caps etc. as headgear from the last many years. However they are less effective because either they do not cover complete head or do not provide proper shadow and ventilation. Scientists have also worked on many headgears like white pagdi, hat with 90 mm brim width and headgear with solar fan system. The use of headgear reduced the effect of heat stress significantly on thermal parameters, physiological parameters and physical discomfort parameters. The developed solar hat with air circulation mechanism was found best among the headgear in reducing the ill effects of heat stress.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Ce livre a pour but de fournir des informations sur le développement et l'étude comparative des couvre-chefs pour les travailleurs agricoles masculins dans des conditions de stress thermique. De nombreuses techniques sont utilisées pour minimiser le stress thermique dans les climats chauds. L'une d'entre elles est l'utilisation d'un couvre-chef qui protège la tête. Depuis de nombreuses années, les agriculteurs utilisent des serviettes, des pagdi, des casquettes, etc. comme couvre-chefs. Cependant, ils sont moins efficaces parce qu'ils ne couvrent pas toute la tête ou n'offrent pas une ombre et une ventilation adéquates. Les scientifiques ont également travaillé sur de nombreux couvre-chefs tels que le pagdi blanc, le chapeau avec un bord de 90 mm de large et le couvre-chef avec un système de ventilateur solaire. L'utilisation d'un couvre-chef a permis de réduire de manière significative les effets du stress thermique sur les paramètres thermiques, physiologiques et d'inconfort physique. Le chapeau solaire développé avec un mécanisme de circulation d'air s'est avéré être le meilleur des couvre-chefs pour réduire les effets néfastes du stress thermique.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Dieses Buch soll Informationen über die Entwicklung und vergleichende Untersuchung von Kopfbedeckungen für männliche Landarbeiter unter Hitzestressbedingungen liefern. Um den Hitzestress in warmem Klima zu minimieren, werden viele Techniken eingesetzt. Eine davon ist die Verwendung von Kopfbedeckungen, die den Kopf schützen. Die Landwirte verwenden seit vielen Jahren Handtücher, Pagdi, Mützen usw. als Kopfbedeckung. Sie sind jedoch weniger wirksam, da sie entweder nicht den gesamten Kopf bedecken oder keinen ausreichenden Schatten und keine ausreichende Belüftung bieten. Wissenschaftler haben auch an vielen Kopfbedeckungen wie weißen Pagdis, Hüten mit 90 mm breiter Krempe und Kopfbedeckungen mit Solarventilatorsystem gearbeitet. Die Verwendung von Kopfbedeckungen reduzierte die Auswirkungen von Hitzestress auf thermische Parameter, physiologische Parameter und Parameter des körperlichen Unbehagens erheblich. Der entwickelte Solarhut mit Luftzirkulationssystem erwies sich als die beste Kopfbedeckung zur Verringerung der negativen Auswirkungen von Hitzestress.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Este livro destina-se a fornecer informações sobre o desenvolvimento e o estudo comparativo de chapéus para trabalhadores agrícolas do sexo masculino em condições de stress térmico. Para minimizar o stress térmico em climas quentes, são utilizadas muitas técnicas. Uma delas é a utilização de chapéus que protegem a cabeça. Desde há muitos anos que os agricultores utilizam toalhas, pagdi, bonés, etc., como chapelaria. No entanto, são menos eficazes porque ou não cobrem toda a cabeça ou não proporcionam sombra e ventilação adequadas. Os cientistas também trabalharam em muitos chapéus, como o pagdi branco, o chapéu com 90 mm de largura de aba e o chapéu com sistema de ventilação solar. A utilização de chapéus reduziu significativamente o efeito do stress térmico nos parâmetros térmicos, nos parâmetros fisiológicos e nos parâmetros de desconforto físico. O chapéu solar desenvolvido com mecanismo de circulação de ar foi considerado o melhor dos chapéus na redução dos efeitos nocivos do stress térmico.…

Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Questo libro intende fornire informazioni sullo sviluppo e lo studio comparativo dei copricapi per i lavoratori agricoli maschi in condizioni di stress da calore. Per ridurre al minimo lo stress da calore in un clima caldo si utilizzano molte tecniche. Una di queste è l'uso di copricapi che proteggono la testa. Negli ultimi anni gli agricoltori hanno utilizzato asciugamani, pagdi, berretti ecc. come copricapo. Tuttavia, sono poco efficaci perché non coprono completamente la testa o non forniscono ombra e ventilazione adeguate. Gli scienziati hanno anche lavorato su molti copricapi, come il pagdi bianco, il cappello con tesa di 90 mm e il copricapo con sistema di ventilazione solare. L'uso del copricapo ha ridotto in modo significativo l'effetto dello stress da calore sui parametri termici, fisiologici e di disagio fisico. Il cappello solare sviluppato con meccanismo di circolazione dell'aria è risultato il migliore tra i copricapi per ridurre gli effetti negativi dello stress da calore.…
