Today, due to climate change, natural hazards and how to deal with them are among the most important concerns of researchers in environmental planning and crisis management. The purpose of this study is the assessment of the potential flood risk in Sarbaz drainage basin. For this purpose, the databases including elevation, slope, geological characteristics, soil characteristics, precipitation, ...
The prevalence of allergies has vastly increased over recent decades due to air pollution and climate change. The present study aims to identify any seasonal variations in the allergens, to help prevent and treat allergic diseases; and investigate any correlations between the reported allergens and other biotic parameters, namely age and sex. The study included 67 subjects (49 female and 18 mal...
The Tennessee River Basin is considered one of the most important regions for freshwater biodiversity anywhere on the globe. The Tennessee River Basin currently includes populations of at least half of the described contemporary diversity of extant North American freshwater fishes, crayfish, mussel, and gastropod species. However, comparatively little is known about the biodiversity of this bas...
The Nam Pat Group of the Nam Pat Basin, Uttaradit Province, Thailand is situated in the Nan Suture Zone. Two contrasting tectonic framework models of the Nan Suture have previously been proposed: as a main Paleo-Tethyan suture and as a remnant of a closed back-arc basin. The goal of this study is to analyze the tectonic framework of the Nan Suture and reevaluate the existing tectonic models. Th...
Oil-gas reservoir exploration using hyperspectral remote sensing, which based on the theory of hydrocarbon microseepage information and fine spectral response of target, is a new direction for the application of remote sensing technology. In this paper, Qaidam Basin and Liaodong Bay in China were selected as the study areas. Based on the hydrocarbon microseepage theory, the analysis of crude oi...
Relationships between distribution of periphytic diatoms and environmental variables in 19 rivers of the Lake Ladoga basin (Northwestern Russia) were examined using gradient analysis. On the basis of geology and river water chemistry, the Lake Ladoga basin could be separated into twomain parts, the northern and the southern sub-basin. The rivers in the northern sub-basin are slightly acidic and...
garra rufa , a bottom dwelling freshwater fish and native to the middle east, is distributed in the southwestern of iran and the tigris basin. considering the importance of length-weight relationships data of a species in different habitats, the length-weight relationship of g. rufa from 13 rivers in the persian gulf and the tigris basins was explored. the value of exponent b ranged from 2.74 t...
The phosphate industry is a major contributor to the economy of many South Mediterranean countries. Large volumes of water are required by the mining industry in areas where water resources are scarce. The integrated management of water in the influence zone of phosphate mines with due respect to other sectors of the economy and populations is a way to further develop these regions. To achieve ...
In Tunisia, cases of zoonotic cutaneous leishmaniasis caused by Leishmania major are increasing and spreading from the south-west to new areas in the center. To improve the current knowledge on L. major evolution and population dynamics, we performed multi-locus microsatellite typing of human isolates from Tunisian governorates where the disease is endemic (Gafsa, Kairouan and Sidi Bouzid gover...
Introduction: One of the most prominent features of Mars is the global south to north slope of ~0.036° [1] discovered by analysis of data from the Mars Orbiter Laser Altimeter (MOLA) aboard Mars Global Surveyor. In contrast, Isidis Planitia, the floor of Isidis basin, slopes southwest at an angle of ~0.02° [2]. It has been suggested [3] that deflection of the lithosphere under a load located in...
