Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding
(Frontiers, 2023)Sorghum is emerging as a model crop for functional genetics and genomics of tropical grasses with abundant uses, including food, feed, and fuel, among others. It is currently the fifth most significant primary cereal crop. ... -
Copper-modified carbon nano-onions as electrode modifiers for the electroanalysis of the antiretroviral drug efavirenz
(Elsevier Ltd, 2023)The high prescription and consumption rate of antiretroviral drugs (ARV) such as Efavirenz (EFV) in South Africa for the treatment of the human immunodeficiency virus (HIV) has resulted in its presence in wastewater and ... -
Cuspal deflection of teeth restored with bulk fill flowable composite resins, with and without fiber-reinforcement and evaluated by micro-computed tomography
(Elsevier, 2023-07)Polymerisation shrinkage of composite resins is a clinical challenge which has been well documented in the literature. Many studies investigating polymerisation shrinkage stress measure cuspal deflection, which is a ... -
