The Water Framework Directives aims a reduction in concentration of hazardous substances in the marine environment. Consequently, there is a need to distinguish between anthropogenically influenced metal concentrations from natural background levels. To better achieve this goal in the Portuguese coast, dissolved and particulate trace metal (TM) concentrations along the Portuguese coast were det...

the concentration of selected trace metals (fe, cd, cu, pb, and zn) in 30surface sediments were measured using atomic absorption spectrometer to investigatethe spatial and seasonal variations of trace metals along kanyakumari coast, india. toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

Since June 1986, the University of Pennsylvania has been under contract with the Coast Guard to provide support for the Coast Guard's KSS (knowledge-based decision support systems) project. A principal output of the KSS project has been Max, a DSS shell or environment, originally designed to support modeling tasks during decision making for ship acquisition. Max is innovative in a number of way...

Background: Declines in semen quality over time are not well understood. It is suspected that infectious disease may affect reproductive function. The aim of this study was to investigate semen quality in men in infertile relationships who were under investigation for couple infertility and attended a clinic for routine semen analysis over a period of 15years. Materials and Methods: We investig...

Silver pomfret, Pampus argenteus is an economically important seafood species. The fishery resource of pomfret in Indian waters shows a dwindling catch since the last few years and the pomfrets caught were mostly undersized which calls for immediate attempts for management of resources. An accurate definition of population structure is important for management of this species. The genetic stock...

geographical location and climatic condition in the northern coast of persian gulf provided a suitable condition for the spread of epidemic diseases and their continuity. in qajar period, increased relations with india, mesopotamia and lack of health facilities caused the death of many residents in these areas. at the beginning of reza shah’s reign and the government’s attitude towards moderniz...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...

BACKGROUND Atlantic Bluefin Tuna (ABFT) shows complex demography and ecological variation in the Mediterranean Sea. Genetic surveys have detected significant, although weak, signals of population structuring; catch series analyses and tagging programs identified complex ABFT spatial dynamics and migration patterns. Here, we tested the hypothesis that the genetic structure of the ABFT in the Med...

One c collaps For thirty years I have read publications about this spate of invasions; and many of them preserve the atmosphere of first-hand reporting by people who have actually seen them happening, and give a feeling of urgency and scale that is absent from the drier summaries of text-books. We must make no mistake: we are seeing one of the great historical convulsions in the world’s fauna a...
