Атомно-абсорбционный спектрометр А-2 это автоматический интеллектуальный инструмент для проведения атомно-абсорбционного анализа в пламенном и электротермическом режиме. Пламенный атомизатор предназначен для работы в следующих режимах: ацетилен – воздух, ацетилен – закись азота, пропан-бутановая смесь - воздух.
This book has been written for those studying petroleum geology or engineering, for whom the role of the petrophysicist can become a lucrative and satisfying career. The handbook will be equally useful to students and practioners of environmental science and hydrogeology, where the understanding of groundwater flow is an important part of their technical remit.
The SP is a passive measurement of very small electrical voltages resulting from electrical currents in the borehole caused by the differences in the salinities (resistivities) of the formation connate water (Rw) and the drilling mud filtrate (Rmf), and by the presence of ion selective shale beds. The voltage changes are measured by a downhole electrode relative to a surface ground. Unlike other logging tools which are displayed on a specific scale with a specified reference value, the SP has no specified origin and values used for computation are referenced to deflection from the nearby shale baseline established by the interpreter. <...>
Agricultural productivity growth is vital for economic and food security outcomes which are threatened by climate change. In the present times, changing climate is a burning issue. Climate change may be limited to a specific region or may occur across the earth.
Настоящее Руководство составлено на основании анализа и обобщения опыта исследования грунтов с повышенным содержанием органики в различных научно-исследовательских институтах и организациях, занимающихся изучением этих грунтов с точки зрения использования их в качестве оснований сооружений, (Калининский политехнический институт, ЦНИИС, НИИ оснований и подземных сооружений, ПНИИИС и др.).
THREE A S TM STANDARDS are available for sampling coal: ASTM Practice for Collection of Channel Samples of Coal in the Mine (D 4596), ASTM Test Methods for Collection of a Gross Sample of Coal (D 2234), and ASTM Practice for Collection of Coal Samples from Core (D 5192). The first two standards are applicable only to existing mining operations, test pits, or transportation of coal.
The purpose of this book is to evaluate the history and characteristics of chromium(VI) in the environment, in industry, and in society. The book was created by the Independent Environmental Technical Evaluation Group (IETEG), a volunteer research organization located in Northern California. It was created in 1997 to present objective scientific and engineering information about controversial environmental issues as a foundation for rational discussion and policy development. The IETEG’s first project was MTBE: Effects on Soil and Groundwater Resources (CRC Press, 2000).
