Capping Ligand Influence on the Structural, Optical and Luminescence Properties of CdTe Nanoparticles Prepared by a Simple Wet Chemical Process
(2019-03)
The nature of the capping ligands used and the strength of their interactions with the surface atoms of the nanoparticles (NPs) impact greatly on the material properties and the stability of the resulting NPs. The structural ...
A multi-institutional, cross-sectional study on disclosure of HIV status to sexual partner(s) and associated factors among people living with HIV/AIDS attending selected hospitals in Kigali, Rwanda
(2020-02)
Background: In Sub-Saharan Africa, human immunodeficiency virus (HIV) remains a public health problem. There is need for evidence-based interventions to curb new infections. HIV status disclosure, especially to sexual ...
Nitrogen-Doped Carbon Nanotubes Synthesised by Pyrolysis of (4-{[(Pyridine-4-yl)methylidene]amino}phenyl)ferrocene
(Hindawi Publishing Corporation, 2013-08-13)
Nitrogen-doped carbon nanotubes (N-CNTs) were synthesized by pyrolysis of (4-{[(pyridine-4-yl)methylidene]amino}phenyl) ferrocene in a solution of either acetonitrile or toluene as carbon source. This was achieved by testing ...
Implementation of genomics research in Africa: challenges and recommendations
(2018-01-16)
Background: There is exponential growth in the interest and implementation of genomics research in Africa. This growth has been facilitated by the Human Hereditary and Health in Africa (H3Africa) initiative, which aims to ...
Semi-Parametric Spatial Joint Modeling of HIV and HSV-2 among Women in Kenya
(2015-08)
Several diseases have common risk factors. The joint modeling of disease outcomes within a spatial statistical context may provide more insight on the interaction of diseases both at individual and at regional level. Spatial ...
Bioactive carbazole alkaloids from Alysicarpus ovalifolius (Schumach)
(CrossMark, 2015)
Phytochemical and biological evaluation of the stem bark of Alysicarpus ovalifolius led to the isolation of three carbazole alkaloids identified as mohanimbine (1), koenimbine (2) and koenidine (3) along with quercetin ...
Analysing Four Factor Second Order Models Using Response Surface Methodology with Application in Germination of Melia volkensii
(2017-12)
Second order models are useful in situations where there are curvilinear effects present in the true response function. Such models have real life applications in a wide variety of fields such as agriculture, biology, and ...
Copper Extraction Using Aluminum in Acidic Leachate Media
(IISTE, 2020)
Copper is found in several minerals with varied elemental composition. For instance, copper minerals occur as chalcopyrite (CuFeS2), bornite (Cu5FeS4), chalcocite (Cu2S), covellite (CuS), cuprite oxide (Cu2O), and malachite ...
Antiplasmodial activity, in vivo pharmacokinetics and anti‑malarial efficacy evaluation of hydroxypyridinone hybrids in a mouse model
(Dambuza et al. Malar J, 2015)
Background: During the erythrocytic stage in humans, malaria parasites digest haemoglobin of the host cell, and
the toxic haem moiety crystallizes into haemozoin. Chloroquine acts by forming toxic complexes with haem ...
