The red cow in Numbers 19 has perplexed scholars for quite some time. paper engages with many of the questions they have raised, but especially why this ritual is called a חַטָּאת and how relates to portrayal Leviticus. explores historical development from possible elimination into two different sacrifices, then which produces substance apotropaic qualities. last phase took place late Persian peri...

In order to leave a livable world future generations, the elimination of environmental pollution, which is one important dimensions sustainability, increases its importance every day. Undoubtedly, among factors that cause role ships quite high. The seas are also polluted by routine operation as well marine accidents. Pollution arising from operations caused discharge pollutants such ballast wat...

Without reclamation of waste liquor and chemicals recovery, the kraft pulp and paper industry would constitute an enormous pollution problem. Already for economical reasons, substantial recovery is secured, however, and considerable further improvements are foreseen. Recovery is outlined in terms of cycles for sodium, calcium, sulphur, and—in a wider sense—carbon. In addition, the mechanical lo...

oil contamination is one of the most common and usual kinds of pollution in aquatic and terrestrial ecosystems. one of the economical and effective methods for decreasing or eliminating oil contamination is using plants and microorganisms. soils contain a wide variety of oil decomposing microorganisms, of which pseudomonad, rhodocoous and nocardia are the most important. to evaluate the effect ...

A new type of bioreactor for air pollution control has been developed. The new process relies on an organic-phase emulsion and actively growing pollutant-degrading microorganisms, made into a foam with the air being treated. This new reactor is referred to as a foamed emulsion bioreactor (FEBR). As there is no packing in the reactor, the FEBR is not subject to clogging. Mathematical modeling of...

Most polymers exhibit high flammability and poor degradability, which restrict their applications and causes serious environmental problem like "white pollution." Thus, titanate nanotubes (TNTs) were adopted to decorate graphene oxide (GO) by a facile solution method to afford TNTs/GO nanocomposites with potential in improving the flame retardancy and photodegradability of flexible polyvinyl ch...

This article uses theory and experiments to investigate voluntary-threat approaches for regulating nonpoint source water pollution. The policies allow a group of polluters to voluntarily meet a pollution standard, under threat of a mandatory tax policy to be implemented in the case of noncompliance. Building upon recent work by Segerson and Wu (2006), who propose what we label an “exogenous” vo...
