Traditional drilling muds frequently have trouble efficiently transporting cuttings to the surface, which impedes drilling efficiency and progress. The possibility of a nano addition to enhance the cutting transport capability of water-based muds (WBM) is examined in this work. This study employed graphene nanoplatelets (GNPs)-based drilling muds made from rice husk waste and modified with Triton-X100 to determine how sandston...
An evaluation of fish and invertebrate mercury concentrations in the Caribbean RegionNARA Subscribed
Mercury is a ubiquitous pollutant of global concern but the threat of exposure is not homogenously distributed at local, regional, or global scales. The primary route of human exposure to mercury is through consumption of aquatic foods, which are culturally and economically important in the wider Caribbean Region, especially for Small Island Developing States (SIDS). We compiled more than 1600 samples of 108 unique species of...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
