چکیده
Abstract The European Water Framework Directive implements the policies to achieve a good ecological status of all waterbodies. To determine potential in freshwater environments, abiotic (morphology, physical and chemical variables) biotics (algae, fishes, etc.) metrics are used. Despite their importance trophic web, zooplankton was not included as one Biological Quality Elements (BQE) water quality. In present research, we studied species that can be considered indicators for more than 60 reservoirs. data were obtained from 300 samples collected during 10 years reservoirs at Ebro River watershed, which is largest basin Spain. According physicochemical biological elements, these established. More 150 identified study. results this research indicate related with low quality are: Acanthocyclops americanus , Ceriodaphnia spp., Daphnia cucullata párvula Diaphanosoma brachyurum Brachionus angularis Keratella cochlearis Phompolyx sulcata . An indicator moderate Bosmina longirostris while longispina Ascomorpha ovalis saltans suggest used valuable tool should considered, near future, BQE within WFD metrics.

Introduction: As a glycoprotein, Plasma Prostate-Specific Antigen (PSA) is mainly produced by prostate epithelial cells and is used as a major diagnostic tool for prostate cancer. A group of researchers relate the elevated number of estrogen receptors in breast cancer samples to the over-production of PSA in this type of cancer. Therefore, the present study aimed to determine the participants' ...

Aggregated journal-journal citations for 1999 are compared with similar data in the Journal Citation Reports 1998 of the Social Science Citation Index. In addition to indicating local change, probabilistic entropy measures enable us to analyze changes in distributions at different levels of aggregation. The indicators are compared by elaborating the journal-journal mappings and in relation to s...
