14,849 affected cases of beta thalassemia have been registered in 1995 in all provinces of iran. it is estimated that there are about three million carriers in iran. the provincial distributions of the affected cases show that the highest incidence in 100 thousand individuals was in mazandaran (71.29) and gilan (57.61), respectively, both near the caspian sea (north), followed by hormozgan (50....

The Eocene tectonic evolution of the easternmost Caribbean Plate (CP) boundary, that is Lesser Antilles subduction zone (LASZ), debated. Recents works shed light on a peculiar period duality in arc/back-arc regions. A compressional-to-transpressional regime occurred north, while rifting and seafloor spreading Grenada basin to south. mechanism for this strong spatial variation its through time h...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...

The growing development of offshore wind energy installations across the North Sea is producing new hard anthropogenic structures in the natural soft sediments, causing changes to the surrounding macrobenthos. The extent of modification in permeable sediments around a gravity based wind turbine in the Belgian part of the North Sea was investigated in the period 2011-2012, along four gradients (...

BACKGROUND Babesiosis is a haemoparasitic disease of domestic and wild animals caused by species of the genus Babesia. Babesia bigemina, B. bovis and B. divergens are known to be pathogenic in cattle. The disease is transmitted during blood feeding by infected ticks and is the most economically important tick-borne disease in tropical and subtropical areas. Ixodid ticks are vectors in the trans...

How the spatial expansion of a species changes at a human time scale is a process difficult to determine. We studied the dispersal pattern of the French white stork population, using a 21-year ringing/resighting dataset. We used the graph-theory to investigate the strength of links between 5 populations (North-East, North-West, Centre, West, and South) and to determine factors important for the...

in this paper the minimum temperatures of 54 weather stations collected for a 31-year period were analyzed for zoning the frost regions in iran. the results of this study show that the average of the number of frost days per year was 62, and the average temperature was 3 degrees of centigrade below zero. dey the tenth month in the iranian calendar, december 22-january 20 with an average of 28, ...

In this paper, a novel corner detection method is presented, to extract geometrically important corners for robot applications, such as indoor mobile robot navigation or manipulation. Intensity‐based corner detectors, such as the Harris corner, can detect corners in noisy environments, but have inaccurate corner positions and miss the corners of obtuse angles. Edge‐based corner det...

West Nile virus spread rapidly from east to west across North America, despite the north-south migratory flyways of its avian hosts. In this issue, Venkatesan & Rasgon (2010) present new data on the population genetics of Culex tarsalis, the dominant West Nile virus vector in the Western United States, suggesting that patterns of mosquito gene flow may better reflect the virus's expansion from ...

the main objective of this research was to analyze the barriers of implementing the total quality management (tqm) in agricultural faculties in the universities of north west of iran. the kind of research method of the study was an analytical- explanatory one. the statistical population of the study consisted of all the faculty members in agricultural faculties in the universities of north west...
