A potential degrader of paraffinic and aromatic hydrocarbons was isolated from oil-contaminated soil from steel plant effluent area in Burnpur, India. The strain was investigated for degradation of waste lubricants (waste engine oil and waste transformer oil) that often contain EPA (Environmental Protection Agency, USA) classified priority pollutants and was identified as Ochrobactrum sp. C1 by...

Performance degradation assessment based on condition monitoring plays an important role in ensuring reliable operation of equipment, reducing production downtime and saving maintenance costs, yet performance degradation has strong fuzziness, and the dynamic information is random and fuzzy, making it a challenge how to assess the fuzzy bearing performance degradation. This study proposes a mono...

A simple, cost effective, stability-indicating reversed-phase high-performance liquid chromatography method was developed for the quantitative determination of bazedoxifene acetate (BAZ) drug substance in the presence of its impurities and degradation products. The method was developed using an X-terra RP-18, 150 × 4.6 mm, 3.5 μm column with a mobile phase containing solvent A, a mixture of 10 ...

HPTLC aluminium plates Preco...

nano-cus powders were synthesized with chemical solution method. xrd and sem and spectrophotometry were used for characterization of the cus powders. xrd analysis indicated that tetragonal cus was the main phase with particle size of 16.2nm and little cu2s phase was present. scanning electron microscopy (sem) analysis revealed that powder was plate like and had very little aspect ratio in morph...

mesoporous tio2 has been prepared using a nonionic block copolymer (pluronic p-123) as structure-directing agent with sol-gel method. characterization of the product was carried out by means of x-ray diffraction (xrd), scanning electron microscopy (sem), thermogravimetry-differential scanning calorimetry (tg-dsc), nitrogen sorption isotherms, and uv-vis absorption spectroscopy. these analyses s...

background: carbaryl (1-naphthyl-n-methyl carbamate) is a chemical in the carbamate family used chiefly as an insecticide. it is a cholinesterase inhibitor and is toxic to humans and classified as a likely human carcinogen. in the present study, the degradation of the carbaryl pesticide was investigated in the laboratory synthetic samples of tap water, in the effect of sonolysis and photolysis ...

the first purpose of this study is to present an alternative robust model in order to describe ruminal degradation kinetics of forages and to minimize the fitting problems. for this purpose, the korkmaz-uckardes (ku) model, which has a logarithmic structure, was developed. the second purpose of this study is to estimate, by using the korkmaz-uckardes (ku)model, the parameters tp (the time to pr...

Duloxetine hydrochloride (HCl) is an antidepressant drug prescribed for major depressive disorders, pain related to diabetic peripheral neuropathy, and stress urinary incontinence. In the present study, degradation behavior of duloxetine HCl was studied by subjecting the drug to various International Conference on Harmonization-recommended stress conditions. Also, a stability-indicating high-pe...

BACKGROUND Adapalene is a retinoid analogue with actions similar to those of tretinoin. It is used in topical treatment of mild to moderate acne. A survey of the literature reveals that no spectrofluorimetric method has been reported yet for determination of ADP, so it was thought necessary to develop a highly sensitive stability indicating spectrofluorimetric method. RESULTS Two highly sensi...
