Geographic variation in shell morphometry is analyzed for three locally endemic springsnail (Gastropoda: Hydrobiidae) species occurring sympatrically in nine limnocrenes of the Cuatro Cienegas Basin, Coahuila, Mexico. Despite some correlation of size-related variables across species, groupings of populations based on multivariate analyses were not very similar among species, nor were they stron...
Side channel spillways have a common usage in conveyance and distribution networks, high dams, water and wastewater treatment plants, and surface drainage networks. A side channel carries spatially varied flow with increasing discharge and their water surface profiles is a main feature in the design process. Usually, the bottom width of the channel is flared in the flow direction and an end sil...
The drainage networks of catchment areas burned by wildfire were analysed at several scales. The smallest scale (1–1000 m) representative of hillslopes, and the small scale (1000 m to 1 km), representative of small catchments, were characterized by the analysis of field measurements. The large scale (1–1000 km), representative of perennial stream networks, was derived from a 30-m digital elevat...
Sand coverings account for a large part of the cost of a project. The purpose of this study is to evaluate the performance of different coatings for filtration of underground drains and reduce the cost of cornfield farms. The experiments were carried out in farm in Salman Farsi. The subsoil drainage was fitted to each test piece with a length of 120 meters, a diameter of 100 mm, and a distance ...
Aims and Backgrounds: Almost no area in the world can be found that has not been affected by tectonic processes. The morpho-tectonic indices of the basin are used to investigate the active tectonics. Morphometry can be defined as the quantitative measurement of the shape of the Earth's landscape that using these quantitative measurements can identify areas with active tectonics. The purpose o...
Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...
Nowadays, acid mine drainage (AMD) is one of the most important problems in coal mine contamination. The Karmozd coal mines in Mazandaran Province are one of the largest and oldest coal extractions in Central Alborze Coal Basin. The samples of coals, host rocks, mine drainages and secondary surface minerals have been collected in summer season of 2005. On the basis of hydrogeochemistry studies ...
BACKGROUND Alterations in the dopaminergic reward system, predominantly the striatum, constitute core characteristics of schizophrenia. AIMS Functional connectivity of the dorsal striatum during reward-related trial-and-error learning was investigated in 17 people with schizophrenia and 18 healthy volunteers and related to striatal grey matter volume and psychopathology. METHOD We used voxe...
