objective: human retinal pigment epithelium (hrpe) is a cell monolayer located in the outer part of the retina that is in contact with photoreceptors. in many diseases rpe cells damage. one way for treating this disease is the implantation of intact instead of damaged cells. for this reason different types of substrates have been used for cell cultivation. this study has used alginate and a ble...

Halophilic and halotolerant microorganisms are good candidates for decolorization of azo dyeswhich are routinely used in the dyeing process in textile industries. In this paper, theoptimization of biological decolorization of synthetic dye solutions containing Remazol Black Bby the previously isolated halophilic bacterium Halomonas sp. D2 is investigated. In a primaryinvestigation using a one-f...

objective: in recent years the use of herbal slimming supplements has increased in iran. one problem may be the illegal inclusion of synthetic drugs by some manufacturers in these products. the aim of this study is to determine four undeclared synthetic adulterants in some herbal slimming products present in the iranian market. methods: this survey studyresearched six common herbal slimming sup...

The aim of this study is to investigate the nitrate adsorption on granular ferric hydroxide (GFH). The effect of factors such as initial concentration of nitrate, pH, contact time, and adsorbent mass were determined. The study was done in laboratory–scale in which synthetic nitrate solutions in a batch reactor were placed in contact with the adsorbent to model adsorption kinetics. It was found ...

Ž . Although dissimilatory iron reducing bacteria DIRB are capable of reducing a number of metals in oxides and soluble forms, the factors controlling the raterextent of magnetite reduction and the nature of the mineral products resulting from magnetite reduction are not well understood. This study was carried out to investigate mechanisms and biogeochemical processes occurring during magnetite...

This paper discusses the use of small satellites for future radar remote sensing applications. After a short introduction, we give first an overview of the TanDEM-X mission to be launched in autumn 2009. Here, special emphasis is put on the demonstration of innovative synthetic aperture radar (SAR) imaging techniques. Then, novel SAR configurations are introduced which make synergistic use of m...

All-male populations are used in tilapia aquaculture because the culture of mixed-sex populations often results in precocious maturation and early reproduction (Mires, 1995). Early maturation shunts energy to gonadal rather than somatic growth. In addition, reproduction in ponds may lead to the harvest of many unmarketable fry. Individuals in mono-sex populations have increased somatic growth r...
