[1] Observations on the West Spitsbergen Shelf have shown that the dynamic response of the shelf to wind forcing has a profound effect on the heat content of the water. Hydrographic and atmospheric data have been analysed with respect to the relative importance of surface heat fluxes and advective processes on ocean temperature. During the Arctic winter of 2005/06 periods of sustained along-she...

with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...

Payments for ecosystem services (PES) policies compensate individuals or communities for undertaking actions that increase the provision of ecosystem services such as water purification, flood mitigation, or carbon sequestration. PES schemes rely on incentives to induce behavioral change and can thus be considered part of the broader class of incentive- or market-based mechanisms for environmen...

Numerous investigations applying the cloning and sequencing of rRNA genes (rDNAs) to the study of marine bacterioplankton diversity have shown that the sequences of genes cloned directly from environmental DNA do not correspond to the genes of cultured marine taxa. These results have been interpreted as support for the hypothesis that the most abundant heterotrophic marine bacterioplankton spec...

in this paper, we introduce environmental systems engineering (ese) and describe some of its applications combined with process systems engineering (pse) to problems related to environmental systems. these systems—the water cycle and ecosystem cycles—are complex and highly dynamic, with an uncertainty level comparable to that of chemical systems. to illustrate the challenges of applying pse to...

Non-tuberculous mycobacteria (NTM) are commonly found in the environment. As exposure to environmental mycobacteria has been reported to immunomodulatory in this study, the presence of environmental mycobacteria was investigated in soil, drinking water and drainage sample in Ghatampur, India, which is known for high endemicity for leprosy. Soil, drinking water from the hand pumps/wells and also...

The plurality of conservation and environmental viewpoints often challenge community leaders and government agency staff as they seek to engage citizens and build partnerships around watershed planning and management to solve complex water quality issues. The U.S. Midwest Heartland region (covering the states of Missouri, Kansa, Iowa, and Nebraska) is dominated by row crop production and animal...

Climate change, world population growth, and poverty have led to an increase in the incidence of leptospirosis. Leptospirosis is caused by pathogenic spirochaete bacteria that belong to the genus Leptospira. The bacteria are maintained in the renal tubules of the reservoir hosts (typically a rodent), then shed into the environment via the urine. Water is key for environmental survival and trans...

This paper addresses the existence of an Environmental Kuznets Curve for China, using a sample of 30 regions, covering the period 1982–1997. The types of pollution included are wastewater, waste gas, and solid waste. We consider the development of the sources of pollution in a pooled cross-section analysis with pollution in absolute levels, in per capita terms, and relative to real Gross Region...
