Explains why Evald Ilyenkov (1924-79) is a serious cultural philosopher whose ideas are of enduring significance. Argues that Ilyenkov offers an intriguing vision of the relation of mind and world, which has radical implications for conceptions of thought, language, and human communication. Attempts to show that one thinker in the Soviet tradition…

Through the use of NASA Tech Briefs, Peter Kask, was able to build a solarized domestic hot water system. Also by applying NASA's solar energy design information, he was able to build a swimming pool heating system with minimal outlay for materials.

The objective of this study was to investigate trends, medical problems, and contributory factors that occurred in 50 sea kayaking incidents in New Zealand between October 1992 and September 2005. There are currently very limited validated data available worldwide about the epidemiology of sea kayaking incidents. The research will raise awareness of how these events happened and their potential for serious harm. It will assist kayakers to manage their sport safely. This was a retrospective epidemiological study of incident reports originally collected by Paul Caffyn for the Kiwi Association of Sea Kayakers (KASK). Variables investigated in this study were geographic location, month, year, participant demographics, incident severity, type of kayak and trip, environmental conditions, safety gear carried, medical problems, cause of deaths, and contributory factors. Tables and graphs were developed to analyze the results. Incidents occurred around New Zealand throughout the year, often in rough seas in offshore winds. More people were involved in September. Fifty-six percent of incidents involved groups; 20% were overseas tourists and 72% were recreational private trips. Eighty-five percent of participants were male, mostly aged 24 to 39 years old, and 48% had little or no experience. The severity of incidents increased with time. Severity was lower for women. Severity was higher in calm conditions and light winds, when the capsized kayaker became separated from the kayak, and when a personal flotation device (PFD) was not worn. Fishing incidents had a higher severity and involved inexperienced kayakers. Human factors contributed to most if not all incidents and occurred more frequently than physical events. Where medical problems were reported, hypothermia and sprains were common. Collision with a powered vessel was often fatal. The study was limited because it was based on relatively small numbers, was unlikely to capture all incidents in New Zealand, and denominator

both and its individual systems including an external respiration function. In this case, it should be remembered that the external respiration system has some physiological and morphological properties due to which the body systems are particularly subjected to environmental effects. Thus, according to figurative comparison by Evald Veible a contact area of the lungs with an external environment i.e. an alveolar surface is large and equaled approximately to tennis-court size, as the alveolocapillary membrane thickness is negligible and amounts to one fiftieth of a writing-paper sheet [1]. From this it follows that such a fine and highly organized structure must be extremely dependent upon any external exposures including gravitational ones since from the physical viewpoint of physics the lungs represent a quasiconical three-dimensional elastic body suspended in the thoracic cavity and in which there occur the gravity-induced internal tensions incrementing in a base-to-apices direction. As a result of these tensions, in the lungs various physical gradients: hydrostatic, pleural and transpulmonary pressures, pulmonary time constant, vertical gradient of the volume and structure of alveoli, etc. are developed.
