'A sort of destiny': the multi-jurisdictional response to sewage pollution in the Great Lakes, 1900-1930.

The Bernoulli Ritz-collocation method to the solution of modelling the pollution of a system of lakes

Pollution has become a very serious threat to our environment. Monitoring pollution is the rst step toward planning to save the environment. The use of dierential equations, monitoring pollution has become possible. In this paper, a Ritz-collocation method is introduced to solve non-linear oscillatory systems such as modelling the pollution of a system of lakes. The method is based upon Bernoul...

Heavy Metal Pollution of Lakes along the Mid-Lower Reaches of the Yangtze River in China: Intensity, Sources and Spatial Patterns

Lakes in the middle and lower reaches of the Yangtze River form a shallow lake group unique in the World that is becoming increasingly polluted by heavy metals. Previous studies have largely focused on individual lakes, with limited exploration of the regional pattern of heavy metal pollution of the lake group in this area. This paper explores the sources, intensity and spatial patterns of heav...

Stability of Antibiotic Resistance Patterns in Agricultural Pastures: Lessons from Kentucky, USA

Animal and human wastes contain fecal bacteria, including pathogens that can contaminate groundwater, streams, lakes, and reservoirs through runoff and infiltration. Bacterial nonpoint sources of pollution continually impair water quality (Hartel et al., 2002). These pollution sources may come from failed septic systems, large animal operations, land application of wastes, sewage treatment faci...

Multi-objective Optimization of Customers’ Load and Local Energy Resources in order to Increase Profitability and Decrease Pollution of Smart Microgrid

In this study, a new multi-objective method is proposed to optimal manage the local energy resources and customers’ load in a microgrid in the presence of demand response programs. The wind turbine and photovoltaic panel are the renewable energy sources of the microgrid. The time of use and critical peak pricing programs are also used to improve the consumption pattern of customers. Moreover, c...
