the relationship between some habitat factors and fish assemblage was analyzed in the taleghan river, alborz province, iran. fish specimens from thirty-three sites were sampled by electrofishing device in october 2014. the habitat parameters, including elevation (m), water depth (cm), river width (m), river slope (%), current velocity (m.s-1), number of large stone (> 15 cm), average stone diam...

Ischemic preconditioning is a form of intrinsic cardioprotection where an episode of sublethal ischemia protects against subsequent episodes of ischemia. Identifying a clinical biomarker of preconditioning could have important clinical implications, and prior work has focused on the electrocardiographic ST segment. However, the electrophysiology biomarker of preconditioning is increased action ...

Landslides are catastrophic geological risks that unexpected. This study aims to develop a Landslide Vulnerability Map of Barangay Fatima, Pantabangan, Nueva Ecija. Mapping has been developed mitigate the adverse effect landslide. interprets and integrate landslide factors; elevation, slope, rainfall, soil classification, land cover, proximity road fault lines generate vulnerability map. The ei...

Introduction: The estimated center and diameter parameters of basins and large craters has been largely based on photogeologic evidence [1], [2], [3]. Since these parameters were published, additional evidence of the shapes of these impact features has been supplied by Clementine's LIDAR elevation data, now available in the form of Digital Elevation Maps (DEMs) [4], [5]. Examination of the new ...

Models of ground surface elevation, slope, aspect, curvature, roughness, deformation, as well as other features are gathered together in the term Digital Terrain Model (DTM). DTMs can be generated from a wide range of technologies such as ground surveying, aerial and satellite imagery, including both active and passive sensors. Some elevationderived parameters, such as roughness and slope can b...

BACKGROUND Schistosomiasis japonica is a parasitic disease that remains endemic in seven provinces in the People's Republic of China (P.R. China). One of the most important measures in the process of schistosomiasis elimination in P.R. China is control of Oncomelania hupensis, the unique intermediate host snail of Schistosoma japonicum. Compared with plains/swamp and lake regions, the hilly/mou...

As the senile phase due and causes depeleting latex productivity, rubberwood stands can still be claimed as carbon sequestration under REDD + Scheme. This is also to maintain vegetation cover in protected forests, beside for fostering social forestry (HKm) sustainability well. Nowadays role of genetic environment factors on production have widely revealed by some researchers, but lack wood espe...

distribution and abundance of plants has been correlated with a variety of complex environmental gradients. environmental factors affect plants growth and need to be understood by ecosystem managers. this study was carried out to examine the relationships between site factors and different vascular and non-vascular plants in north of iran. for this purpose, vegetation and soil sampling was perf...
