nowadays, air pollution is a global problem that has had significant growth by technology development, population growth andindustrial development. industrial development brought natural resources deterioration, more manufacturing products, and more environmental pollutants. if pollutant won’t be controlled, human-being and wildlife will face the critical risks. significant release and critical...
Abstract The goal of present study is determining subsurface structural elements by analyzing geomagnetic data sets aiming to examine their impacts on geological surface structures characterizing the western region in Beni-Suef Governorate, Western Desert, Egypt. A land-magnetic survey conducted two exceedingly sensitive proton magnetometers measure total intensity field at under investigation....
Since the emergence of West Nile virus (WNV) in North America in 1999, there have been several reports of WNV activity in Central and South American countries. To detect WNV in Brazil, we performed a serological survey of horses from different regions of Brazil using recombinant peptides from domain III of WNV. Positive samples were validated with the neutralisation test. Our results showed tha...
introduction dominant process in arid and semi-arid region is dynamic of wind that carries the sand and caused damage to several facilities and human settlements. there are many human settlements with low population and mostly small and scattered in different parts of foothills of dasht-e lut (lut desert), especially in mountainous margins of alluvial fans. residential and cultivation area of t...
We present fossil pollen data and discuss their climatic interpretations from a 688-cm-long sediment core from Hurleg Lake, a freshwater lake located in the Qaidam Basin on the NE Tibetan Plateau, just beyond the northern limit of the East Asian summer monsoon influence. The reconstruction of the Holocene vegetation and climate history was aided by modern surface pollen analysis. The 14000-yr c...
Patterns of spatial variation in biological diversity represent one of the central themes in modern biogeography and ecology (Rosenzweig, 1995; Gaston & Williams, 1996). Much of the knowledge about these patterns available to date is based strictly on studies of free-living organisms (Rosenzweig, 1995), whereas patterns of parasite diversity have until now attracted Ramon Science Center and Mit...
