Неблагоприятная деятельность человека прямо или косвенно влияет на окружающую среду. В результате развития такие виды деятельности, как строительство, транспорт и производство, не только истощают природные ресурсы, но и производят большое количество отходов, что приводит к загрязнению воздуха, воды и почвы. Сегодня загрязнение окружающей среды стало не только национальной, но и международной проблемой. Развитые и развивающиеся страны, которые быстро прогрессируют в области сельского хозяйства, технологий и промышленности, постоянно выбрасывают в биосферу различные вредные вещества, тем самым создавая серьезную угрозу для окружающей среды. Основными источниками загрязнения воды являются бытовые, сельскохозяйственные и промышленные отходы, которые сбрасываются в природные водоемы. Бытовые стоки с сельскохозяйственных полей, напичканные пестицидами и удобрениями, загрязняют водоемы. Часто используемые пестициды могут нанести вред живым организмам, домашним животным и окружающей среде. Загрязнение воды обычно вызвано различными человеческими источниками, как правило, (точечными и неточечными) промышленными объектами и агрохимикатами, особенно в водной экосистеме, и стало серьезной экологической проблемой в наши дни.

First E.C. Conference on Solar Heating

Contributors to this Conference have shown the wide range of active and passive solar heating systems which have been researched, installed and monitored in recent years throughout western Europe and elsewhere. Yet much remains to be done if solar heating is to reach its full potential. The Conference Committee hopes that this record of the proceedings will provide a basis for the further development of these systems. Many difficulties have been surmounted in arriving at today's position. The foundations of the growing confidence of architects and engineers are to be found in the concerted programmes of research and development mounted by ty,'o of the sponsors of the Conference the European Community and the International Energy Agency. Some of the more tangible products of these programmes have been reported here: component and system behaviour has been subjected to rigorous scientific study; new test facilities have been founded; test procedures devised; simulation methods developed and evaluated; design rules formulated and checked against measured performance. It has been apparent here that the willingness to exchange information and experiences, which has always been a feature of the solar energy scene, remains as strong as ever. A further information-sharing initiative was noted on the part of another sponsor, UNESCO - the setting-up of the European Cooperative Network on Solar Energy, involving countries from both eastern and western Europe.

This paper is written in the belief that people are important and that equipment is to serve the needs of the people and therefore should be designed to meet their specific needs and environment. This is particularly important in the case of a developing country when a professional engineer accepts the responsibility to formulate policies evaluate equipment imple ment projects and train national people. 1. Government, geography and climate Papua New Guinea, an independent and self governing state since 1975, is located directly North of Australia above the North Eastern State of Queensland. The country extends from 141° east longitude, at the border with Indonesia (Irian Jaya) to 160° east longitude and between latitudes 1° and 12° south (see figure 1). Papua New Guinea is a parliamentary democracy, with a single legis lature known as the National Parliament (1). The State is divided into 19 provinces plus the National Capital District (Port Moresby) with de centralized Government established in each province. Before independence the country comprised the Australian territory of Papua in the southern regions and the United Nations Trust Territory of New Guinea in the North (1). Land area is 462,840 square kilometres This inclUdes the mainland, the three large islands of New Britain, ~ew Ireland and fiougainville plus 600 small islands and archipelagos. Approximate direct distances from the capital city of Port Moresby to some of the other centres are : Vanimo 990 km, Rabaul SOO km, Arawa 990 km and Lorengau S25 km.
Demon Accords book 16. Combat is literally her middle name, Chimeric Adaptive Enhanced Combat Operator, but now Caeco Jensen works for the FBI, building a new life and trying to learn from a painful past. It's hard to fit in when you are one of a kind, but maybe, just maybe, there's a place for her in this world. That is if threats from off planet don't ruin it first. Forging and protecting a new future with a her unique skillset won't be easy, maybe almost as hard as making new friends.
This is a guidebook to the mammals of East and Central Africa aimed at scholars and tourists as well as governments concerned in determining quickly and accurately the field status of those species covered. It provides notes on and illustrations of each species including information on their habits, behaviour and how that affects their future survival. Their conservation is considered, particularly in view of the conversion of large amounts of natural habitats into arable land for human food production. The guide may therefore serve as a tool in bringing to light the fact that hard decisions need to be made by the various States to enter into active partnerships with land owners who accommodate large numbers of the mammals dealt with in the guide. It is hoped that visitors to the national parks and reserves covered will find their safaris more interesting and rewarding and play a role in the promotion of this conservation message.
