This work quantifies the agricultural water footprint (WF) of production (WFprod, agr) and consumption (WFcons, agr) and the resulting net virtual water import (netVWi, agr) of 365 European river basins for a reference period (REF, 1996–2005) and two diet scenarios (a healthy diet based upon food-based dietary guidelines (HEALTHY) and a vegetarian (VEG) diet). In addition to total (tot) amounts...

Splash basins are used in arthroplasty cases to wash instruments. Several studies in the literature have shown these basins being a potential source of bacterial infection. This study assesses the risk of contamination of intraoperative splash basins used to wash and store instruments. A total of 46 random clean primary arthroplasty cases (32 hips, 13 knees, and 1 unicondylar knee) were studied...

In the northern suburbs of Chicago, stormwater catch basins are the primary source of vector mosquitoes targeted by the local mosquito abatement district, and therefore effective catch basin larvicides are needed. From June to September 2011, Natular XRT was applied at label rate to a cluster of 20 catch basins and compared to a cluster of 20 untreated basins all within a small 0.21 km2 area of...

the systematics, morphology, distribution, biology, economic importance and conservation of the spiny eel ( mastacembelus mastacembelus ) of iran are described, the species is illustrated, and a bibliography on this fish is provided. the single species is distributed in southern iranian basins, including karkheh, karun, jarrahi and helleh river basins, mostly part of the tigris river and persia...

Coalbed methane (CBM) plays an important role in coal mining safety and natural gas production. In this work, The CBM potential of B2 seam in Parvadeh IV coal deposit, in central Iran, was evaluated using a combination of local regression and geostatistical methods. As there were 30 sparse methane sampling points in the Parvadeh IV coal deposit, no valid variogram was achieved for the methane c...

Introduction: Heavy metals are regarded as toxic stable elements in the environment that with the entry into water sources, finally it enters into the biological cycle of life and develops some adverse effects. Therefore, the present study aimed to determine the concentration of chromium and arsenic heavy metals in the river basins of Baft and Ravar dams. Methods: This descriptive cross-sect...
