Machine learning (ML)-based models are popular for complex physical system simulation and prediction. Lake is the important indicator in arid semi-arid areas, to achieve proper management of water resources a lake basin, it crucial estimate predict dynamics, based on hydro-meteorological variations anthropogenic disturbances. This task particularly challenging regions, where scarcity poses sign...
Arid environment is a dry landscape or region that received an extremely low amount of precipitation. Arid areas are located where vegetation cover is sparse to almost nonexistent. Almost one third of earth land surface is arid or desert. Over desert areas, a number of land cover patterns can be observed. One example is given here for the Arabian Peninsula. The located area can be found in Fig....
Stereology was used to quantify components within the kidney of honeyeater birds. Arid zone and wet zone inhabiting 'matched' body mass pairs of birds were examined. The kidney structure of the arid zone white-fronted honeyeater, Phylidonyris albifrons (16.9 g), was compared with that of the wet zone New Holland honeyeater, Phylidonyris novaehollandiae (21.9 g), and that of the arid zone spiny-...
Original scientific paper Evaluating the deterioration of ecological environment and vegetation of coalfields caused by China’s large-scale coal mining activities is important because of the fragile ecological environment and low temperature in cold and arid areas. This study takes the open coal pits of Haizhou, Gulianhe, and Huolinhe as examples and proposes a method for evaluating their ecolo...
Distribution of dengue virus types in Aedes aegypti in dengue endemic districts of Rajasthan, India.
BACKGROUND & OBJECTIVE Dengue haemorrhagic fever (DHF) is the major cause of sustained morbidity/ mortality among human cases of dengue in dengue endemic areas of Rajasthan. Screening of mosquitoes collected from disease endemic settings and typing the virus could provide significant epidemiological information for prospective risk of DHF. We therefore carried out a study on different dengue vi...
In the arid and semi-arid area's rainfall have considerable changes in terms of time and amount that make the water resource management an important issue. In this research, using both Boolean and Fuzzy logic were zoned potentiality suitable areas for construction of underground dams. The study area is located in the central region of Ardabil province with 7461 km2 area and semi-arid climate. F...
Management of underground resources has a special priority in arid and semi-arid in Iran. Increasing underground resources is one of the useful ways for providing water requirements during the drought years. The main objective of this study was for mapping underground dam in the arid and semi-arid area in western Iran. The first and important stage of underground dam construction is recogn...
