Viscoelastic fluid flow over a horizontal flat plate with various boundary slip conditions and suction effects.

This study examines the numerical representation of fluid flow on the Maxwell model in a double-diffusive boundary layer over a horizontal plate. The investigation incorporates slip conditions, encompassing momentum slip, thermal slip, and suction parameters. Moreover, the study includes the inspiration of thermal radiation, heat generation, and mass transfer.

Bioremediation by oil degrading marine bacteria: An overview of supplements and pathways in key processes.

Oil spillage is one of the most common pollutants which brings greater economic loss and damage to the environment. The intensity and amount of the damage may vary depending on factors such as the type of oil, the location of the spill, and the climatic parameters in the area. As for any pollution management, the guidelines are Reduce, Re-use, Recover and Disposal.

Differential Involvement of β'-COP Isoforms in Plant Development.

Coat protein I (COPI) is necessary for intra-Golgi transport and retrograde transport from the Golgi apparatus back to the endoplasmic reticulum. The key component of the COPI coat is the coatomer complex, which is composed of seven subunits (α/β/β'/γ/δ/ε/ζ) and is recruited from the cytosol onto Golgi membranes. In mammals and yeast, α- and β'-COP WD40 domains mediate cargo-selective interactions with dilysine motifs present in canonical cargoes of COPI vesicles.

Valorization of food waste and poultry manure through co-composting amending saw dust, biochar and mineral salts for value-added compost production.

The present study proposes a system for co-composting food waste and poultry manure amended with rice husk biochar at different doses (0, 3, 5, 10%, w/w), saw dust, and salts. The effect of rice husk biochar on the characteristics of final compost was evaluated through stabilization indices such as electrical conductivity, bulk density, total porosity, gaseous emissions and nitrogen conservation. Results indicated that when compared to control, the biochar amendment extended the thermophilic stage of the composting, accelerated the biodegradation and mineralization of substrate mixture and helped in the maturation of the end product.

Integrated thermophilic enzyme-immobilized reactor and high-rate biological reactors for treatment of palm oil-containing wastewater without sludge production.

Bacillus pumilus, the thermophilic microorganism, was used to biosynthesise lipase of specific activity 5173 U. The purified lipase was highly stable in the pH range from 1 to 7 and temperature at 50 °C. The functionalized nanoporous activated carbon matrix was used for the immobilization of lipase at the optimum conditions and was used for the hydrolysis of palm oil-containing wastewater at optimum time, 3 h, pH 7, and at temperature 50 °C.

Nanoemulsion drug delivery by ketene based polyester synthesized using electron rich carbon/silica composite surface.

A new carrier matrix for nanoemulsion drug delivery was synthesized from glycine as the raw material, using mesoporous/microporous electron rich carbon-silica composite surface (MAC(800)). MAC(800) was prepared from rice husk in two-stage carbonization. The surface area, pore volume, and pore size distribution of MAC(800) were measured, using nitrogen adsorption isotherms at 77K.

A novel amphiphilic nano hydrogel using ketene based polyester with polyacrylamide for controlled drug delivery system.

A ketene based Low molecular weight polymer (LMKP) having ester functional group was prepared using glycine through surface initiated anionic polymerization. NMR, ATR-FTIR & SEC were used to characterize the LMKP. The LMKP and acrylamide (AAm) were co-polymerised in methyl ethyl ketone to yield semi-IPN nanohydrogels (NHG).

Immobilization of polyphenol oxidase onto mesoporous activated carbons -- isotherm and kinetic studies.

Investigations were carried out in batch modes for studying the immobilization behavior of polyphenol oxidase (PPO) on two different mesoporous activated carbon matrices, MAC400 and MAC200. The PPO was immobilized onto MAC400 and MAC200 at various enzyme activities 5 x 10(4), 10 x 10(4), 20 x 10(4), 30 x 10(4)Ul(-1), at pH 5-8, and at temperature ranging from 10 to 40 degrees C. The intensity of immobilization of PPO increased with increase in temperature and initial activities, while it decreased with increase in pH.

Faecal prevalence of extended-spectrum Beta-lactamase (ESBL)-producing coliforms in a geriatric population and among haematology patients.

Antimicrobial resistance to the extended-spectrum cephalosporins is increasingly reported worldwide. In the local setting, nosocomial infections with multi-resistant Gram-negative bacilli are not uncommon and are a growing concern. However, there is limited data on the carriage rates of such organisms in the local setting.

Epitope mapping from real time kinetic studies - role of crosslinked disulphides and incidental interacting regions in affinity measurements: study with human chorionic gonadotropin and monoclonal antibodies.

Real time kinetic studies were used to map conformational epitopes in human chorionic gonadotropin (hCG) for two monoclonal antibodies (MAbs). The epitopes were identified in the regions (alpha 5--14 and alpha 55--62). The association rate constant (k+1) was found to be altered by chemical modification of hCG, and the ionic strength of the reaction medium.
