in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...

there are described nanocomposites based on ultra high molecular weight polyethylene and graphite nanoplates prepared by in-situ polymerization method. it is carried out a comprehensive study of electric properties of these composites, including direct current (dc) and alternating current (ac) properties. there is explored dependence of the conductivity and dielectric permeability on filler con...

juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. the development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. we encountered a 36-year-old woman with a palpable mass in the right breast. the radiologic findings were indicative of a fibroadenoma in the breast. sonographic guided ...

purpose : to compare changes in posterior corneal elevation, anterior chamber depth (acd), anterior chamber volume (acv) and corneal volume (cv) after laser in situ keratomileusis (lasik ) and photorefractive keratectomy (prk) for low to moderate myopia by pentacam imaging methods : in this prospective comparative case series, 105 consecutive myopic eyes randomly scheduled for lasik (n=59) or p...

Ilmenite, aluminum and graphite can be used to produce in-situ Al2O3/TiC–Fe composites which are used as cutting tools. Few publications can be found in the literature that discusse the effect of molar ratio of aluminum and graphite on the Al2O3/TiC–Fe formation mechanism. Therefore, the present research is designed to make the issue clear.  To achieve this goal, at first, the mechanism o...

silver-polyaniline (ag-pani) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (aot) solution as an emulsifier. the synthesis of silver-polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (aot), concentration of oxidation agent and c...
