Behavioral factors which can influence preservation of young people's health

Young people play a most important role in society's life as they possess significant intellectual, creative, labor and reproductive potential. However, this potential might not find its implementation in reality due to both inevitable reduction in number of people belonging to this population category and deteriorating quality of it. And a key issue here is preservation of young people's health. Contemporary young people have poorer health than the previous generations and we can observe a so called "social ill health funnel". There is another acute issue related to demographic losses caused by mortality among young people; they die due to outer causes, circulatory system diseases, malignant neoplasms, and digestive organs diseases, and this mortality is to a great extent determined by behavioral factors. The paper dwells on the analysis of basic self-preservation behav-ioral parameters determined via a sociological questioning performed among people living in Vologda region.

Fast food is also more popular with young people: 39 % eat it several times a week. And sometimes it is a desire to overcome a stress that makes young people smoke, drink alcohol or eat unhealthy foo

Mercury in Mid-Ocean ridges (on the example of Mid-Atlantic ridge and East Pacific rise)

Data on mercury distribution within the rocks and ores of the Mid-Atlantic Ridge and East Pacific Rise are presented. The results are discussed from the standpoint of mercury degassing of the Earth. Materials on its modern manifestation in the Ocean are given. A comparison of mercury has been made for the present day rift and paleorift by the example of Mid-Atlantic Ridge and Ural province
