This paper proposes a new multi-objective based adaptive immune algorithm for solving the combined economic and environmental dispatch problem. Economic dispatch problem deals with the minimization of fuel cost while satisfying a set of equality and inequality constraints. The fossil fuel plants pollute the environment by emitting some toxic gases. Therefore, the traditional minimization of cos...

Hipparcos parallaxes and proper motions have made it possible to construct Hertzsprung-Russell (HR) diagrams of nearby clusters with unprecedented accuracy. The standard deviation of high fidelity non-binary non-variable stars about a model stellar evolution isochrone in the Hyades cluster is about 0.04 magnitudes. We use this deviation to estimate an upper limit on the scatter in metallicities...

Rapid industrialization in the 1960s caused heavy metals such as cadmium (Cd) to severely pollute soil in Japan. The Agricultural Land Soil Pollution Prevention Law was enacted in 1970 to cope with the heavy metal pollution. Cd, in particular, has been recognized as one of the most detrimental elements in Japan because of the so-called “itai-itai” disease caused through Cd uptake. Recently, the...

As the degree of instruction-level parallelism in superscalar architectures increases, the gap between processor and memory performance continues to grow requiring more aggressive techniques to increase the performance of the memory system. We propose a new technique, which is based on the wrong-path execution of loads far beyond instruction fetch-limiting conditional branches, to exploit more ...

Tanneries generate wastewater in the range of 30 to 35L kg skin/hide processed with high salinity, high oxygen demand, high organic loading and a high salt content one of which is chromium which spoils the agricultural land and pollute the ground water. In the present investigation, the bacterial strains were isolated from the contaminated soil which was collected from in and around the tannery...

This paper considers the equity implications of vehicle emissions taxes by examining the incidence of a tax on local pollutants. It uses emissions data from the California Air Resources Board and household vehicle and income data from the US Consumer Expenditure Survey. It incorporates household price responsiveness that differs across income groups into a consumer surplus measure of tax burden...

Forest pests and diseases is very important to forest because it not only restricts the development of forest, but also causes huge economic. Chemical pesticides control the pests and diseases effectively and pollute environment seriously. How to reduce the amount of pesticide is the research hotspot in the field of plant protection. Forest plant protection machinery is the most important way t...

The article talks about the relationship of Chechen people with nature, which from time immemorial were built on fundamental principles human community, and worldview proceeded integrity living inanimate as they are interconnected mutually conditioned, therefore have an equal degree importance for harmonious functioning universe. Flora fauna, micro- macrocosm, inanimate, rational irrational par...

Large amounts of copper slag are produced every year and major fractions it currently disposed, not withstanding the multiple ways material can be used. Application is often limited by presence hazardous elements their leaching behavior so they potentially pollute soil, surface water underground water. To remove such treatment necessary. However, to implement industrially also needs fulfill req...

Rapid industrialization and consumerism have aggravated the generation of industrial waste globally, consequently posing a serious problem related to their treatment, disposal, management. Industrial wastes or sludges are mainly characterised by undesirable levels heavy metals, toxic chemicals, other organic compounds. Deposition such in environmental matrices for prolonged periods may result c...
