The Physiological Effects of High Altitude covers the concepts and principles in high altitude physiology. This book is divided into four main sections that discuss the adaptive mechanisms in natural acclimatization and the bodily processes of exercise at high altitudes. Some of the topics covered in the book are the development of chronic mountain sickness; comparison of growth and development of the rat at high altitude; body weight during early acclimatization; experiments on wound healing and activity of the adrenocortical system; and experiments on pregnancy and lactation. Other sections deal with the volume and structure of erythrocytes and hemoglobin at high altitude, particularly the responses of deer mice to altitude. This book also examines the hematologic changes during rest and physical activity in man at high altitude. The remaining sections are devoted to the hematologic changes during physical activity, as well as the hypoxic stimulus and mechanism of erythropoiesis. The book can provide useful information to doctors, students, and researchers.
The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military...
This book covers studies on the systematics of plant taxa and will include general vegetational aspects and ecological characteristics of plant life at altitudes above 1000 m. from different parts of the world. This volume also addresses how upcoming climate change scenarios will impact high altitude plant life. It presents case studies from the most important mountainous areas like the Himalayas, Caucasus and South America covering the countries like Malaysia, Sri Lanka, India, Nepal, Pakistan, Kirghizia, Georgia, Russia,Turkey, Indonesia, Malaysia and the Americas. The book will serve as an invaluable resource source undergraduates, graduate students, and researchers.
Nine well-trained subjects were tested on a complex performance device designed to assess functions of relevance to aircrew activities. The tests, which involved tracking, monitoring, and mental arithmetic, were performed during exposure to altitude (14,000 feet) and heat (60 C.) both singly and in combination. Several physiological measures were taken. Exposure durations were 30 minutes for each condition with both pre- and post-testing. The only clear-cut effects of the conditions were significant differences across the environmental conditions on a perceptual-motor tracking task related to manual aircraft control. Altitude was clearly a more powerful variable than temperature in this stud...
