Adsorption parameters optimization of spent coffee ground biochar for methylene blue removal using response surface methodology.

This study investigates the potential of spent coffee ground biochar (SCGB) as a sustainable and cost-effective adsorbent for the removal of methylene blue (MB), a hazardous dye commonly used in the textile and printing industries. A response surface methodology (RSM) approach with central composite design (CCD) was employed to systematically investigate the effects of key process parameters, including adsorbent dosage, solution pH, contact time and temperature, on MB removal efficiency. The analysis revealed that adsorbent dosage and temperature as critical factors influencing MB removal, with a linear model providing a strong correlation.

Quantitative determination of C-polysaccharide in Streptococcus pneumoniae capsular polysaccharides by enzyme-linked immunosorbent assay.

Capsular polysaccharides of Streptococcus pneumoniae are used in pneumococcal polysaccharide and protein-conjugate vaccines. Cell-wall polysaccharide (C-Ps) is a critical impurity that must be kept at low levels in purified polysaccharide preparations. Hence, accurate and precise methods for determining C-Ps are needed.

Oral health practices related risk factors and prevalence of dental caries in Armed Forces: A multicentric study.

Background: Dental caries is a multifactorial disease known to be associated with the individual's lifestyle and attitude to health. Prevalence of dental caries in military personnel is higher due to their rugged profession, where soldiers endure the toughest of hostilities. The aim of this study was to assess the prevalence of dental caries in Indian Armed Forces and its association with oral health related behaviours, i.
