Agricultural intensification is associated with the use of great amounts of agrochemicals that may result in the accumulation of metals in soils, and –subsequently—agricultural products and food chain. Nowadays, this is a major concern for many Iranian agricultural products, necessitating scientific researches on the issue. Therefore, the present study has been conducted to evaluate the level o...
background: in recent year, the accreditation process as the most important assurance and improvement of the quality of higher education, especially in medical sciences, has been set forthed. the need for accreditation of nursing faculties as the same of medical sciences has been acutely felt. yet there are not compiled standards at the same time, to describe present and desirable quality via a...

abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...
This paper intends to study the accumulation of copper oxide nanoparticles (CuO NPs) on hepatopancreas and muscle tissues in Shrimp L. vannamei. The CuO NPs were synthesized through chemical sequestration and were studied by precise techniques of FTIR, SEM, AFM, XRD, and DLS, and then their accumulation on L. vannamei were evaluated. In this research, the bioaccumulation of CuO particles on hep...
Background: From the perspective of health promotion, the most critical mission of hospitals is to change the treatment-oriented mindset to a health-oriented one. Health promoting hospitals seek to institutionalize the concept of prevention and health promotion. Therefore, the current research aims to study Kashan, Aran and Bidgol hospitals in achieving health promotion standards in 2020. Me...
today, information technology and computers are indispensable tools of any profession and translation technologies have become an indispensable part of translator’s workstation. with the increasing demands for high productivity and speed as well as consistency and with the rise of new demands for translation and localization, it is necessary for translators to be familiar with market demands an...
Background: Artemia urmiana are small crustaceans that because of its non-selective filter feeder pattern potentially may absorb high level of heavy metals through their living environment. In this study, the effects of different levels of cadmium and copper on survival, catalase activity and metals bioconcentration rates in A. urmiana nauplii have been investigated. Methods: The research wa...
Heavy metals are one of the main groups of environmental pollutants; enter the aquatic environment through natural and human activities. These metals may accumulate in aquatic organisms including fish and be a potential danger to the health of the ecosystem and living organisms, especially for human beings. In this study, the amount of heavy metals including copper, zinc, and nickel was investi...
Paired vegetable/soil samples from New York City and Buffalo, NY, gardens were analyzed for lead (Pb), cadmium (Cd) and barium (Ba). Vegetable aluminum (Al) was measured to assess soil adherence. Soil and vegetable metal concentrations did not correlate; vegetable concentrations varied by crop type. Pb was below health-based guidance values (EU standards) in virtually all fruits. 47% of root cr...
