Two internal transcribed spacer (ITS1 and ITS2) sequences of the non-coding region of the rDNA and a 16S RNA gene fragment of the mtDNA of Oncomelania hupensis, the intermediate host snail of Schistosoma japonicum in mainland China, have been investigated with a view to illustrate the influence of the environment on genetic differentiation. Thirteen populations of O. hupensis snails, representi...
Over recent decades, the South Branch Potomac River, West Virginia, has experienced fish kills and episodes of suppressed health in adult that have spanned small stretches to nearly 120 km contiguous habitat. Although factors such as endocrine disruption, chemical contaminants, infectious agents been detected, no single causal mechanism identified. To gain information about temporal nature abno...
Water Quality Index and Environmental Assessment of Rosetta Branch Aquatic System, Nile River, Egypt
This study was carried out on Rosetta branch water and 3 drains (El-Rahawy, El-Soble El-Gezira) that discharging wastewater into it, to assess the Water Quality Index (WQI) of their waters. investigation performed during period starting from winter 2017 summer 2018. The mean annual averages WQI values were good poor for irrigation (up 55) very aquatic life 97) at stations exposed discharged bra...
Dendrites form predominantly binary trees that are exquisitely embedded in the networks of the brain. While neuronal computation is known to depend on the morphology of dendrites, their underlying topological blueprint remains unknown. Here, we used a centripetal branch ordering scheme originally developed to describe river networks-the Horton-Strahler order (SO)-to examine hierarchical relatio...
