Investigation of turbulency on the rate of induced liquid circulation, gas hold-up, mixing time and overall gas–liquid volumetric oxygen mass transfer coefficient. The various types of surfactants (containing Brij58, TritonX-405, Tween40, HCTBr) with various concentrations of 1-5 ppm were examined on the operational characteristics of the reactor. In surfactant solutions (in comparison with pur...

A novel and sensitive floatation-spectrophotometric method is presented for determination of trace amounts of thorium in water samples. The method is based on the ion-associated formation between thorium, Eriochrome cyanine R and Brij-35 at pH = 4 media. The complex was floated in the interface of the aqueous phase and n-hexane by vigorous shaking. After removing the aqueous phase the floated p...

In order to identify integral proteins and peripheral proteins associated with the plasma membrane, highly purified Arabidopsis plasma membranes from green tissue (leaves and petioles) were analyzed by mass spectrometry. Plasma membranes were isolated by aqueous two-phase partitioning, which yields plasma membrane vesicles with a cytoplasmic-side-in orientation and with a purity of 95%. These v...

Introduction: The objective of this task is to succeed with the trial an ocularly efficient Timolol maleate formulation produced from prolonged proniosomal gel niosomes get significant therapy for glaucoma. Methods: Cholesterol, Lecithin, Span 60, Brij 72, and Tween 80 in various concentrations were used create loaded derived utilizing phase coacervation method. Found on these outcomes entrapme...

Dowex 50. The resin, kindly supplied by Dow Chemical International Ltd., Midland, Michigan, U.S.A., was stated to be of nominal 12% cross-linking and 200-400 mesh. Sodium phosphate buffer pH 6-8, 0.1M. This buffer was adjusted to pH 6-75 in order to delay slightly the emergence of the histidine peak. At the lower pH, histidine emerges separated from and almost mid-way between hydroxylysine and ...

Rifabutin is wide spectrum antimicrobial agent, effective in the treatment of infection caused by M. tuberculosis, avium and Leprae also used multidrug resistant TB. very poorly water soluble drug (0.19mg/ml) with high permeability. For enhancement solubility a hydrophobic has significant role development liquid dosages form. The main purpose this study was to improve co solvency method. Differ...

Essential oils (EO), which can be extracted from different edible, therapeutic and herbal plants, have been well known as natural antimicrobial additives. However, it is usually hard to attain high efficacy of these EOs, when are used in combinations for the control foodborne microbes, because their low solubility water interactive binding. Here, we report an optimized oil-in-water (o/w) nanoem...
