The effect of acute hypobaric hypoxia on local sweating and cutaneous blood flow was studied in four men and four women (follicular phase of menstrual cycle), who exercised at 60% of their altitude-specific peak aerobic power for 35min at barometric pressures (Pb) of 770 Torr (sea level), 552 Torr (2,596 m), and 428 Torr (4,575 m) at an ambient temperature of 30 deg C. We measured esophageal temperature (Tes), mean skin temperature (T sk, 8 sites), and local sweating (ms) from dew-point sensors attached to the skin at the chest, arm, and thigh. Skin blood flow (SkBF) of the forearm was measured once each minute by venous occlusion plethysmography. There were no gender differences in the sensivity (slope) or the threshold of either ms/Tes relationships for the three regional sites decreased with increasing altitude, although these differences were not significant between the two lower PBs. The slope of SkBF/T was reduced in five of the eight subjects at 428 Torr. Enhanced body cooling as a response to the higher evaporative capacity of the environment is suggested as a component of these peripheral changes occuring in hypobaric hypoxia.

The effect of hypobaric hypoxia on the relation of regional sweating to body temperature rise was studied in four men and four women (follicular phase of menstrual cycle) who exercised 40 and 60% of their altitude specific peak aerobic power at 770 Torr (sea level), 552 Torr (2596m), and 428 Torr (4575m) in 20 C or 30 C for 35 minutes. Body temperature and sweating at the chest (C), arm (A) and thigh (T) were measured continuously from dew point sensors attached to the skin. No gender differences were found in either the sensitivity (slope) or the threshold of the sweating to body temperature for any site during any combination of exercise intensity, altitude or environmental temperature. In all experimental conditions, the mean body temperature threshold for the initiation of A (36.7 C) sweating was higher (P

The International Hypoxia Symposium convenes biannually to bring together international experts from many fields to explore the state of the art in normal and pathophysiological responses to hypoxia. Representatives from five continents and 32 countries joined together in February 2003 for four days in the dramatic mountains of Banff, Alberta. As editors of the Proceedings of the International Hypoxia Symposia, we strive to maintain a 26 six year tradition of presenting a stimulating blend of clinical and basic science papers focused on hypoxia. Topics covered in 2003 include hibernation and hypoxia, hypoxia and fetal development and new advances in high altitude pathophysiology, oxidative stress and membrane damage, hypoxic regulation of blood flow, heat shock proteins in hypoxia, and future directions in hypoxia research. In 2003 we also had the privilege ofhonoring John W. Severinghaus as a friend, colleague, mentor and inspiration to many in the field. Tom Hornbein's personal tribute to John Severinghaus is the first chapter in this volume, followed by an entertaining update of the history of the discovery of oxygen written by John Severinghaus.

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.
