Classification of means for rise of liquids from vertical and subvertical mountain developments of various purpose is resulted on the basis of pressure head characteristics of the equation of D. Bernulli for non-stationary currents. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/137209 Экологические аспекты повышения эффективности геоло-горазведочного бурения Вдовиченко, А.И. The basic direktions of increasing the effectiveness of geologcical-ecsploration drilling are considered in aspecte solving of ecological problems. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/137208 Задача термоупругости для полусферического тела с покрытием Бондаренко, Н.А.; Жуковский, А.Н.; Мечник, В.А.; Панов, А.В.; Казьмин, А.О. The axisymmetric problem of thermoelasticity for spherical diamond bit in hole drilling conditions is solved. The peculiarity of the problem is in that stresses themselves depend on temperature nonlinearily but the equilibrium conditions include the components of volume force vector. The problem solution is represented in terms of Legendre polinomials and spherical functions which enable to define the components of quasi-static thermoelastic stresses at a random point of time and to analyze the main factors influencing on kinetics of the given process. 2007-01-01T00:00:00Z http://dspace.nbuv.gov.ua:80/handle/123456789/135958 Титульные страницы и содержание 2007-01-01T00:00:00Z
