Study on community structure of microbial consortium for the degradation of viscose fiber wastewater
BACKGROUND Enrichment culture was applied to obtain microbial consortium from activated sludge samples collected from biodegradation system, a chemical fiber plant in Hebei Province, China. Bacterial composition and community dynamic variation were assessed employing denaturing gradient gel electrophoresis fingerprinting technology based on amplified 16S rRNA genes in the entire process of enri...
متن کاملImpact of Oxygen-Reinforced Alkali Extraction on Eucalyptus Sulfate Pulp for Viscose Fiber Production
Some pulp mills expect to produce viscose fiber by means of pre-existing pulp production lines as used for conventional kraft pulp having a relatively high content of hemicellulose. In the present study oxygenreinforced alkali extraction was used to dissolve the oxidized lignin, which increased the content of alpha cellulose and increased the degree of mercerization. This paper considers the in...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...
15 صفحه اولWorkshop on fiber toxicology research needs.
A great deal of toxicological and epidemiological data are available for asbestos and a wide variety of other mineral and manmade fibers. Experimental animal data suggest that certain fiber characteristics are responsible for observed biological effects such as cancer. An important fiber characteristic appears to be fiber size (length, diameter, aspect ratio); however, other characteristics suc...
