On 3 April 2017, a Mw 6.5 earthquake occurred in Botswana, representing the secondstrongest earthquake registered since 1949. Such an intraplate event occurred in a low seismic hazard area and was suspected to be an artificial earthquake induced by nearby anthropogenic activities (gas extraction). The possible relation between anthropogenic activities and the earthquake occurrence has been qual...
The Khuzestan plain is located in south western of Iran and is covered about 3.9 percent of the country area. Khuzestan plain is mostly covered by the Quaternary deposits. The thickness of these deposits exceeds 300m in some areas .Sedimentology and geochemistry of sand dunes producing centers are not only important for determining sedimentary and geochemical features of the particles possible ...
Anthropogenic activities affect the rivers and entire basin in different dimensions. All river basins including Ganga Damodar are polluted from unplanned anthropogenic activities. This study is an attempt to access quality of Shilabati River by computing water pollution index using eleven parameters pH, COD, BOD, DO, TDS, Total Hardness, Alkalinity, Phosphate, Chloride, Nitrate, Turbidity measu...
abstract in first part of this project, the use of a new and biguanid-like catalyst supported on silica as a recyclable catalyst provides a new route for the synthesis of a variety of arylalkylidene rhodanine derivatives through knoevenagle reaction in at present of solvent at room temperature. rhodanine derivatives and especially arylalkylidene rhodanines have proven to be attractive compound...
Most rivers worldwide are highly regulated by anthropogenic activities through flow regulation and water pollution. Environmental flow regulation is used to reduce the effects of anthropogenic activities on aquatic ecosystems. Formulating flow alteration-ecological response relationships is a key factor in environmental flow assessment. Traditional environmental flow models are characterized by...

The Plitvice Lakes National Park is situated in a pristine and sparsely populated area of the northwestern Dinarides, central Croatia. The basic geomorphological phenomenon of the Park consists of 16 karst lakes interconnected by numerous cascades and waterfalls, formed by travertine barriers. During the last century the area experienced significant changes regarding the prevailing anthropogeni...
Nanomaterials are widely used in health and biomedical applications, however, only a few studies investigate their toxic effects. The present report signifies a contribution to the study of the toxic effects of silver nanoparticles on E. coli cells, which is a model organism of anthropogenic pollution. The toxicity of nanoparticles depends on their chemical and surface properties, shape and ...
