Modelling Selective CO Absorption and Validation via Photosynthetic Bacteria and Chemical Adsorbents for Methane Purification in Anaerobic Fermentation Bioreactors.

This study delves into advanced methane purification techniques within anaerobic fermentation bioreactors, focusing on selective CO absorption and comparing photosynthetic bacteria (PNSB) with chemical adsorbents. Our investigation demonstrates that MgO-Mg(OH) composites exhibit remarkable CO selectivity over CH, substantiated through rigorous bulk and surface modelling analyses. To address the challenges posed by MgCO shell formation on MgO particles, hindering CO transport, we advocate for the utilisation of MgO-Mg(OH) composites.

Evaluation of average glandular dose (AGD) in screening and diagnostic digital mammography and digital breast tomosynthesis (DBT) towards establishing a reference dose range band (DRB): a developing country experience.

This study represents the first national survey conducted in Sri Lanka to establish national diagnostic reference levels (NDRLs) for screening and diagnostic acquisitions in digital mammography (2D-DM) and digital breast tomosynthesis (DBT). Additionally, the study investigated the relationship between average glandular dose (AGD) and compressed breast thickness (CBT) and introduced a novel concept called dose range bands (DRBs) as a tool for optimizing radiation dose in mammography. DICOM metadata was used to extract dose data and exposure parameters from women undergoing either screening (350) or diagnostic (750) DM.

Reactogenicity to ChAdOx1 nCoV-19 vaccine in health care workers: A multicenter observational study in Sri Lanka.

Introduction: The acceptability of a vaccine is an important factor during mass vaccination programs and this is largely dependent on the symptoms of local and systemic reactogenicity. There is paucity of data on the systemic and local reactions experienced by COVD-19 vaccine recipients in South Asia.

Objectives: To identify the early local and systemic reactogenicity of ChAdOx1 nCoV-19 vaccine.
