A multicriteria decision making approach for ranking gastric cancer drugs based on topological indices and physicochemical properties

Abstract Chemical graph theory offers a mathematical approach to molecular structure representation and physicochemical property investigation through descriptors based on graph theory. In this study, a QSPR model is developed for analysis of some gastric cancer drug molecules by...

From ownership to stewardship: reimagining intellectual property governance through the Knowledge Commons Framework

Contemporary intellectual property (IP) governance remains strongly shaped by proprietary logics of exclusivity, control, and rights allocation, even as knowledge production becomes increasingly collaborative, cumulative, and digitally mediated. This study examines how the Knowle...

Lead-free Cs2MH6 (M = Ge, Sn) vacancy-ordered double perovskites for optoelectronic applications: a first-principles study

Abstract Lead-free vacancy-ordered double perovskite hydrides are gaining attention as environmentally friendly materials for next-generation optoelectronic applications. In this work, first-principles density functional theory (DFT) calculations are employed to systematically in...

COMPARATIVE ASSESSMENT OF KNOWLEDGE, ATTITUDES AND PRACTICES REGARDING ANTIMICROBIAL USE AND RESISTANCE AMONG CATTLE FARMERS UNDER EXTENSIVE PRODUCTION SYSTEMS IN KOINADUGU AND FALABA DISTRICTS, SIERRA LEONE

Antimicrobial resistance (AMR) threatens animal health and food safety, yet evidence on livestock farmers’ antimicrobial use in Sierra Leone remains limited. This study compared knowledge, attitudes and practices (KAP) regarding antimicrobial use and AMR among cattle farmers in e...

INVESTIGATION OF FARMERS KNOWLEDGE, ATTITUDE AND PRACTICES ON THE USE OF ANTIMICROBIALS AMONG CATTLE FARMERS, WITH IN KOINADUGU DISTRICT SIERRA LEONE

Antimicrobial resistance (AMR) is an increasing One Health threat, particularly in low-resource livestock systems where veterinary services, diagnostic capacity and antimicrobial-use surveillance are limited. This study assessed cattle farmers’ knowledge, attitudes and practices...

Assessment of Anthropometric Indicators of Maternal Malnutrition among Pregnant Women in Nongowa Chiefdom, Kenema District, Sierra Leone

Maternal malnutrition remains a major public-health concern in Sierra Leone, yet community-level evidence based on objective anthropometric measurement is scarce. This study assessed anthropometric indicators of maternal malnutrition among pregnant women attending antenatal care...
