The Mayang River in Jember Regency has a length of approximately 145.50 km which is the longest river and can irrigate an area 5,860 hectares. use by community produce waste, both domestic agricultural livestock waste. Waste that enters directly into bodies cause decrease water quality create pollution load. Therefore, measurement load capacity was conducted. samples were taken using grab sampl...

Surface water pollution is a major problem/ occurrence in the Niger Delta region of Nigeria. Mmubete stream never an exception. significant to people Rivers State owing its usefulness terms fishing activities and domestic usage. The modelling using regression analytical method with emphasis on incorporating mixing properties reaeration prediction was carried out. Water samples were collected an...

The effects of deprivation of oxygen on proliferation kinetics of in vitro grown Ehrlich ascites tumor cells were studied by means of flow cytometry. The flow cytometric results obtained by applying the BUdR-H 33258 technique showed that 6--8 hours after establishment of anaerobiosis cells lose their capacity for proliferation and accumulate in the late G1-phase; during this time late S cells e...

Self-purification plays an important role in water regulating ecosystem services aimed at protecting river quality from pollutant inputs. The Citarum River is the longest West Java, Indonesia where has declined due to inputs domestic and non-domestic activities. This study aims investigate status of self-purification influence upstream River, Cihawuk Majalaya segments, which are rural urban are...

Every river gets polluted as it moves from its source to the end. Hence, quality of water requires investigation for usability. In present work 40.69 km stretch Tungabhadra in Davangere district Karnataka, India was chosen testing quality. The samples’ physical, chemical and biological characteristics were tested eight sites each month during pre-monsoon, monsoon post-monsoon seasons 2017 2019....

[1] The Chicxulub asteroid impact produced massive extinction in terrestrial environments most likely through an intense heat pulse and subsequent widespread fires. Aquatic environments were shielded from this heat and fire but nevertheless showed massive extinction in marine environments and, for reasons unexplained, far less extinction in freshwater environments. Extinction in marine environm...
