introduction: discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. the aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. materials & methods: this study was performed experimentally and in laboratory scale. in this re...

Dental cementum is a specialized calcified structure covering the root of a tooth. This study aims to investigate cementum using various stains which can be exceedingly useful in investigation, observation and diagnosis. 4µm sections of 25 extracted normal teeth, 25 cases of various cemental pathologies and 25 ground sections were stained using cresyl violet, H/E, toluidine blue and periodic ac...

decolorization of remazol brilliant blue r (rbbr) by trametessp. pellets was studied in a batch reactor. dye removal process was performed in shaken flasks which contained 100 ml of rbbr aqueous solution and fungal pellets. the process was followed for 48 h and the dye removal was analyzed at a visible spectrum of 590 nm. response surface methodology (rsm) employing box behnken design at three ...

I N 1955 RIGAS ET AL.1 and Gouttas et al.2 independently reported the discovery of a new hemoglobin characterized electrophoretically at pH 8.6 by a more rapid anodal mobility than that of normal adult hemoglobin. This hemoglobin has subsequently been identified by the letter “H.” More recently, “fast” hemoglobins other than “H” have been described. These include hemoglobins J,3 J,4-1#{176} K,5...

PURPOSE To evaluate the selectivity and strength of intraoperative trypan blue staining during removal of epiretinal membranes (ERMs) and the internal limiting membrane. METHODS Based on intraoperative videos, 51 consecutive chromovitrectomies in 51 patients with macular holes, macular pucker, vitreomacular traction syndromes, or persistent macular edema were retrospectively studied. Fifteen ...

I The continuous faecal marker chromic oxide, Cr,O,, and the intermittent marker brilliant blue were used together in metabolic balance studies of calcium and magnesium in two young women. 2. Faecal output was derived by four methods: no marker, brilliant blue, Cr,Os, or both brilliant blue and Cr,Os. 3. Balances of Ca and Mg derived by the four methods of obtaining faecal output were compared....

The objective of the present study was to establish a methodology using tracer substances for the evaluation of the distribution and amount of spray deposits, with the possibility to adjust the surface tension of the spraying solution. The following products were tested: 0.15% Brilliant Blue, 0.15% Saturn Yellow in 0.015% Vixilperse lignosulfonate and 0.005% sodium fluorescein, and mixtures of ...
