Abstract Because the electricity storage of renewable energy is irregular, battery in this system will be impacted by current. This also have a negative impact on life, increase project cost and lead to pollute environment. study proposes method improve life: hybrid super-capacitor lead-acid key solve these problems.

This paper analyzes the local properties of the symmetric interior penalty upwind discontinuous Galerkin method (SIPG) for the numerical solution of optimal control problems governed by linear reaction-advection-diffusion equations with distributed controls. The theoretical and numerical results presented in this paper show that for advection-dominated problems the convergence properties of the...

Continuous cropping obstacle is a big problem of Strawberry planting. leads to the accumulation phenolic acids, imbalance soil microorganism, deterioration physical and chemical properties, resulting in sharp decline yield quality. At present, prevention cure continuous an urgent be solved. The pathogen does not produce drug resistance, safe fresh fruit pollute environment.

water is the origin of life. 3/4 of the earth's surface is covered by water and all living things must have water to survive. life without water can not be considered. despite this, of all living things only humans exploit, waste and pollute this vital natural resource. raising awareness of the people on this issue is of great importance. at this point, environmental education is a key con...

Pathologies related to neurotoxicity represent an important percentage of the diseases that determine the global burden of diseases. Neurotoxicity may be related to the increasing levels of potentially neurotoxic agents that pollute the environment, which generates concern, since agents that affect children may increase the incidence of neurodevelopmental disorders, affecting the quality of lif...

Wastewater treatment is essential to protecting the environment and human welfare. Water is a resource that is fundamental to human life, which makes taking action to protect the resource on the forefront of research. Treated wastewater effluent is a possible source that can pollute receiving water bodies and cause contamination. It is often discharged into larger bodies of water that are used ...

Poultry, swine, and pre-ruminant calves have limited ability to digest phytate, the storage form of about 80% of total phosphorus in plant-based feedstuffs. The resulting excess phosphorus excretion in manure, upon application to farmlands, can leach into and pollute water bodies. Even so, a 1989 report to EPA on the costeffectiveness of Best Management Practices to reduce non-point phosphorus ...

This paper examines the problem of achieving global cooperation to reduce greenhouse gas emissions. Contributions to this problem are reviewed from noncooperative game theory, cooperative game theory, and implementation theory. We examine the solutions to games where players have a continuous choice about how much to pollute, and games where players make decisions about treaty participation. Th...

background: soil serves as a major reservoir for contaminants as it can bind to various chemicals. the aim of this study was to evaluate the levels of some metals (cd, cu, fe and v) in soil samples collected from different stations of ahvaz industrial complex ii to determine the natural and anthropogenic contribution of metal in the soil. methods: this was an experimental study that carried out...
