Monitoring the water quality of recreational beaches is only one step toward understanding microbial contamination -- the primary cause of beach closings. The surf zone sediment reservoir is typically overlooked and may also be important. This study involved monitoring the fecal indicator bacteria (FIB) levels in water and sediment at three ocean beaches (two exposed and one enclosed) during a ...

Today's most of microorganisms are used for purification of hazard waste such as municipal and industrial waste water and oil contaminants. In this study 2 bacterial species were isolated and purified in hydrocarbon (anthracene) containing media from oil polluted sediment of Imam Khomeini port. Bacillus pasteurii and Amphibacillus xylanus species were identified as indicator degrading bacteria ...

BACKGROUND The morbidity of pancreatic resection remains high, with pancreatic fistula being the most common cause. The important question is whether any postoperative treatment adjustment may prevent the development of clinically significant postoperative pancreatic fistulae. Recent studies have shown that intraabdominal drains and manipulation using them are of great importance. Although auth...

Water requirements of paddy fields in the Gilan Province are provided for by a large irrigation network including Sepidrud reservoir dam, Tarik diversion dam, Fumanat network, Sangar diversion dam, and Sangar right and left canals. Because of the deposition of sediments in the Sepidrud reservoir, its capacity has been reduced profoundly. To overcome this problem, sediments are flushed in the se...

Jökulhlaups in Iceland may originate from marginal or subglacial sources of water melted by atmospheric processes, permanent geothermal heat or volcanic eruptions. Glacier-volcano interactions produce meltwater that either drains toward the glacier margin or accumulates in subglacial lakes. Accumulated meltwater drains periodically in jökulhlaups from the subglacial lakes and occasionally durin...

Inadequate knowledge of baseline conditions challenges ability for monitoring programs to detect pollution in rivers, especially where there are natural sources of contaminants. Here, we use paleolimnological data from a flood-prone lake ("SD2", informal name) in the Slave River Delta (SRD, Canada), ∼ 500 km downstream of the Alberta oil sands development and the bitumen-rich McMurray Formation...

introduction: better use of water and soil resources in paddy fields, increase in rice production and farmer's income, installation of subsurface drainage system is necessary. the main goalof these systems, are aeration conditions improvement prevention of water logging, yield increase, land use increase and multiuse of the land. in different countries, installation of subsurface drainage cause...

The survival of the faecal indicator organism Escherichia coli (E. coli) in recreational coastal water and sediment was investigated using laboratory based microcosms. Intact sediment cores from three distinct coastal sites in metropolitan Adelaide were inoculated with known concentrations of E. coli and incubated at temperatures of 10°C, 20°C and 30°C. Enumeration of E. coli in sediment and ov...

The issue of the transport of dissolved nutrients and contaminants between the sediment in the bottom of a lake or reservoir and the body of water above it is an important one for many reasons. In particular the biological and chemical condition of the body of water is intricately linked to these mass transport processes. As the review by Boudreau (Rev Geophys 38(3):389–416, 2000) clearly demon...

OBJECTIVE After an observational study on 50 patients determined the efficacy and safety of a small calibre (19F), flexible, fluted spiral drains with round cross-section after non-cardiac thoracic surgery we undertook a prospective study to compare these drains to standard chest drains also in terms of pain using a Visual Analog Score. METHODS One hundred consecutive patients who had to unde...
