The value rheology of drilling mud must be in accordance with the conditions wellbore that do not lead to occurrence problems at time drilling. One efforts improve is by adding Carboxymethyl Cellulose (CMC) which useful for increasing viscosity and binding water. This study aims identify effect on use CMC originating from jackfruit skin rheological properties mud. Jackfruit an underutilized org...

the aim of this study was to investigate the barrier properties of cellulose nanocrystals-pvananocomposites. nanocomposite films with different filler loading levels (3, 6, 9 and 12% by wt) weredeveloped by solvent casting method. the effect of cellulose nanocrystals on the barrier properties ofthe nanocomposites was studied. to this end, moisture absorption, water vapor permeability (wvp),oxyg...

The introduction of programmes to detect bladder cancer in people exposed to carcinogens and the increased interest in the value of urinary cytology as a diagnostic procedure have resulted in the need for a satisfactory method of preparing specimens. Ideally, the method must be simple to perform and reproducible, and result in a high degree of cellular clarity and minimal cellular distortion. V...

The o-nitrophenylsulfenyl group, and amino protecting group in the chemical synthesis of peptidyl-tRNA was used to attach newly synthesized peptidyl-tRNA to a benzoylated DEAE-cellulose column. This facilitated the isolation of a highly purified specific tRNA with a well defined peptide chain.

The anaerobic batch digestion of freeze-dried and ground (< 1.5 mm) maize silage, wheat straw, cattle manure, pig cellulose filter paper was investigated with substrates placed in polyester bags. Gas production dynamics bagged non-bagged were compared. By using bottles running parallel those used for gas measurement, could be sampled over time various parameters measured both substrate bulk liq...

the effect of different carbon sources on bacterial cellulose production by gluconacetobacter xylinus (ptcc 1734) and two newly isolated strains (from vinegar) under static culture conditions was studied. the production of bacterial cellulose was examined in modified hestrin-shramm medium by replacing d-glucose with other carbon sources. the results showed that the yield and characteristics of ...

The clarification of biological feed stocks during the production of biopharmaceutical proteins is challenging when large quantities of particles must be removed, e.g., when processing crude plant extracts. Single-use depth filters are often preferred for clarification because they are simple to integrate and have a good safety profile. However, the combination of filter layers must be optimize...
