Aquatic environments are among the most vulnerable habitats that affect all Organisms. The Persian Gulf is home to numerous plant and animal species, biological safety at risk due its human activities. Traffic of oil commercial vessels in area, waste water, desalination, proximity industrial, refinery petrochemical units shores rivers, rigs, fishing, tourism activities potential hazards environ...

background: copper is a trace element vital to life, but the toxic effect of water pollution with it on fish is now exhibited. fish blood is susceptible to contamination-induced stress and its alternation due to the hematological and immunological parameters can be utilized as toxicity indices of xenobiotics. methods: in this study, juvenile species of silver carp with average weight of 200gr w...

using of microorganisms to remove industrial pollutions of environment is an efficient methodthat mimics natural process and decrease remediation cost. in this study, 450 actinomycete strains wereisolated from high metal content soils in iran. heavy metal salt solutions in different concentrations were usedto isolate the resistant strains. 40 resistant actinomycetes which they showed highly res...

This study proposes a new use of data envelopment analysis (DEA) for assessing economic success and environmental protection, so measuring the level of sustainability. The new approach is referred to as “DEA environmental assessment,” and it can measure the performance of various entities that use inputs to produce not only desirable outputs but also undesirable outputs. DEA models are generall...

Although environmental pollution was first realized to be a threat to public health in the latter part of the 20th century, events in the 21st century have served to increase the public awareness of the impacts of environmental pollution. Several communities, including the scientific community initiated dialogues to help protect the planet from environmental pollution. Further, scientific commu...

We explore the possibility of extracting the weak phase γ from pure tree decays Λb → Λ(D0,D0,D0 CP ) in a model independent way. The CP violating weak phase γ can be determined cleanly, without any hadronic uncertainties, as these decay modes are free from the penguin pollutions. Furthermore, neither tagging nor time dependent studies are required to extract the angle γ with these modes. Typese...
