The present study investigated the effect of sumac (SWE) and Rosemary water extracts (RWE) on microbial growth in ground beef meat during refrigerated storage. The meat samples were explored for changes in TVC, E.coli (0157:H7) and S.aureus populations. Antimicrobial effectiveness of extracts was more pronounced against Gram-positive strain compared with Gram-negative strain. Antimicrobial impa...

Protection of ground water for present and future use requires monitoring and understanding of the mechanisms controlling long-term quality of ground water. In this study, spatial and temporal trends in concentrations of nitrate and pesticides in ground water in the eastern San Joaquin Valley, California, were evaluated to determine the long-term effects of agricultural and urban development on...

Seepage-face boundaries are common features of unconfined ground water flow. These boundaries exist at the intersection of an unconfined aquifer and a surface water body such as a lake, river, or wetland. The existence of a seepage-face boundary is necessary to provide a physical transition between the internal water-table boundary and the external equipotential boundary when an unconfined aqui...

abstract a sub-sample of lentil (lens culinaris medik. cv. kimia) seeds was kept as bulk (s1) and another sample was separated to large (s2) and small (s3) seeds. a sub-sample of each size was kept as control or high vigor seed lot (a1) and the two other sub-samples were artificially aged for 2 and 4 days (a2 and a3, respectively). field performance and some physiological traits of plants from ...

THE city of Pulaski in Giles County, Tenn., affords an area in which the intermittent fluoridation of water can be studied. The effect on the teeth of children of intermittent fluoridation of a municipal water supply has not been reported. The Pulaski water supply is derived from Richland Creek, while the surrounding area is served by ground water. The intermittent fluoridation of the water sup...
