This paper studies fishery strategies in lakes, seas, and shallow rivers subject to agricultural industrial pollution. The flowing pollutants are modeled by a nonlinear differential equation general manner. logistic growth model for the fish population is modified cover pollution impact on rate. We start presenting stability analysis of dynamical system discern different types evolution accordi...

theoretical review of ‘mining pit lakes’ indicates that like natural lakes such lakes display a huge diversity. they are typically in a non-equilibrium state with respect to their surroundings. hence, at the decommissioning phase of mining operation a detailed technical study are required on different aspects of such created water bodies considering its morphometry, geology, hydrology, water qu...

Water pollution can be found in the oceans, seas, rivers and lakes which taken as organic pollutants or better known emerging pollutants. Emerging (EP´s) are chemical substances that persist environment, these molecules food chain causing risks adverse effects for human health environment. EP´s not they discharged effluents indiscriminately, this reason is important to improve water treatment b...

Introduction: For the majority of the Cassini Mission, Titan’s hydrocarbon lakes and seas were observed to be quiescent and remarkably calm, with vertical deviations of less than a millimeter[1,2,3,4,5]. This lack of observable surface roughness has been attributed to a seasonal effect in which polar winds were too weak to create waves or other dynamic features[6]. As northern spring approached...

In the United States and other coastal nations, ocean acidification has quickly become a common topic of scientific research. Ocean acidification also has become a public concern as news headlines warn of this potentially threatening byproduct of global climate change. In March 2009, the U.S. Congress passed the Federal Ocean Acidification Research Monitoring Act, a bill to establish an interag...

The globally warm climate of the early Pliocene gradually cooled from 4 million years ago, synchronous with decreasing atmospheric CO2 concentrations. In contrast, palaeoceanographic records indicate that the Nordic Seas cooled during the earliest Pliocene, before global cooling. However, a lack of knowledge regarding the precise timing of Nordic Seas cooling has limited our understanding of th...

This study examined how Twitter was used by all U.S. state education agencies (SEAs) for public engagement in education. Drawing on the ecological model of communication, this study analyzed the latest 71,913 tweets from 40 SEAs that had official Twitter accounts. The results of correlation analysis indicate no significant relationship between the SEAs’ presence on Twitter and the SEAs’ targete...

pattern of feeding and reproduction of amblypharyngodon mola (hamilton, 1822) was studied in two floodplain lakes of north 24 parganas districts of west bengal in india during 2011.  results indicated that the fish exhibited a predominantly herbivorous diet with algae as the main content of gut. a long, thin walled, coiled gut and closely packed filamentous gill racker suited this feeding habit...
