environmental pollution of subsurface due to the long time required to detect the onset of infection and spent considerable time and costs, has a special sensitivity. the aim of this research was, investigating the exact type and behavior of pollutants, assesses environmental attributes and measurement of some important factors of oil contamination in soils around the refinery and how the range...

introduction pyrite oxidation and acid mine drainage (amd) are the serious environmental problems associated with the mining activities in sulphide ores. the rate of pyrite oxidation is governed by the availability of oxygen (borden, 2003). therefore, the identifying oxygen supplying mechanism is one of the most important issues related to the environmental assessment of waste rock dumps (cathl...

Plant productivity is directly affected by the capacity of the root system to forage for soil resources. An enhanced understanding of root-soil interactions provides the potential to improve crop performance in specific soil environments. Interactions between roots and soil are, however, complex. The root-soil environment is heterogeneous and difficult to visualise and measure, root architectur...

Haematite and haematite bearing rocks is a common raw material in Palaeolithic. Widespread in nature, it occurrs either in isolated oucrops or in privileged litostratigraphic formations (in Central Europe these are Lower Devonian, Lower Permian, Lower Triassic and Upper Triassic rocks). All must have provoked an interest of Palaeolithic people so we have searched for a fingerprint for all. So f...

A fundamental problem related to the paleoenvironmental study of early Earth rocks and minerals, and astrobiological exploration of planetary materials (e.g., asteroidal and Mars meteorites, Martian rocks) is not only recognizing and quantifying carbon-related compounds that may be present but also differentiating those molecules formed abiotically from those generated by extinct or extant life...

Soil nitrate and mineralizable nitrogen are used to predict the root yield potential and N fertilizer needs of sugarbeets. Predicting the required N fertilizer for optimum refined sucrose production based on soil test procedures is needed because inadequate N limits root yield and high levels of N may reduce both extractable sucrose and sucrose yield. Sugarbeets (Beta vulgaris L.) were grown at...

This study was conducted to determine long-term thermal regime of landfill liner systems using a field temperature monitoring program and numerical analysis of heat transfer. Temperatures in liner systems that contain geosynthetic clay liners (GCLs) were monitored prior and subsequent to waste placement. Data were collected in three cells at a landfill in Midwestern USA for more than five years...

Survey was made of a beech-maple forest by the quarter point method during August, 1968. The forest is located on a mesic, level upland of the glaciated Allegheny Plateau in eastern Cuyahoga County, Ohio, in the Chagrin River drainage basin. Geologically the upland is underlain by Mississippian formations capped by a thin cover of till, in which soils of the Ellsworth soil catena—the Rittman an...
