Organic pollutants have grown to be a serious global problem because of their massive creation, widespread application, and eventual discharge. Due biomagnification, accumulation, harmful acute chronic impacts on all living things, these substances significantly increased the load ecosystem its potential threats. Reducing risk factors associated with organic contaminantsthrough rhizospheric mic...

The contamination of paddy soils by arsenic (As) is a serious problem in rice production areas across the world. This study investigates the effect selenium (Se) has on the formation of iron plaques on the outside of rice roots and the accumulation of As in rice plants. A soil combined sand pot experiment having four concentrations of Se (0, 1, 5 and 10 mg kg -1 ) and two concentrations of As (...

Capital accumulation has been one major issue in fishery economics over the last two decades, whereby the interaction of the fish and capital stocks were of particular interest. Because bio-economic systems are intrinsically complex, previous efforts in this field have relied on a variety of simplifying assumptions. The model presented here has been substantially extended and avoids some of the...

the aim of the present study was to assess the bio-trickling filter startup for the treatment ofwastewater produced by pegah dairy company at psychrophilic condition. the startup time of a bio-tricklingfilter is directly proportional to the concentration of microbial population. abio-trickling column with a height of150 cm was packed with lava rocks with the liquid recirculated through the pack...

This study, it was aimed to be enabling to use of fish scale as a bio-indicator for heavy metal pollution that is gradually increase in natural waters. For this purpose scaled carps, Cyprinus carpio (Linnaeus, 1758) were exposed to 7.5, 15, 30 and 60 μg L concentrations of trivalent chromium for 21 day and deformities appearing on the scales were examined under electron microscopy. It was found...

Climate change occasioned by the accumulation of greenhouse gases (GHGs) is now widely accepted as an issue which mankind needs to address. The starting point is necessarily the determination of all the sources of emissions during the life-cycles of the studied components. Post-calculation, the results ought to be presented to decision-makers in a clear manner so as to provide the basis on whic...

Nanoclay can be incorporated into emerging dual functional drug delivery systems (DDSs) to promote efficiency in drug delivery and reduce the toxicity of doxorubicin (DOX) used for thyroid cancer treatment. This paper reports the expansion of the basal spacing of kaolinite nanoclay was expanded from 0.72 nm to 0.85 nm, which could provide sufficiently spacious site for hosting doxorubicin molec...
