Synthesis of mesoporous akaganeite functionalized maize cob biochar for adsorptive abatement of carbamazepine: Kinetics, isotherms, and thermodynamics
(Cleaner Materials, 2022-07-17)
In this work, akaganeite (β-FeO(OH)) impregnated maize cob biochar (Fe-MCB) was prepared by direct hydrolysis, and its adsorptive potential was tested against aqueous solutions of carbamazepine (CBZ), an emerging contaminant. ...
The Cell Membrane of a Novel Rhizobium phaseoli Strain Is the Crucial Target for Aluminium Toxicity and Tolerance
(CELL, 2022-03-03)
Soils with low pH and high aluminium (Al) contamination restrict common bean production, mainly due to adverse effects on rhizobia. We isolated a novel rhizobium strain, B3, from Kenyan soil which is more tolerant to Al ...
High-performance liquid chromatography local reference ranges of hemoglobin fractions (HbA, HbA2, and HbF) in detection of hemoglobinopathies in western Kenya
(The Egyptian Journal of Internal Medicine, 2022-12-29)
Background
Western Kenya, being a malaria-endemic region, has a high prevalence of hemoglobinopathies mostly sickle cell and thalassemia. The hemoglobin fractions or variants, HbA, HbA2, and HbF, serve as biomarkers for ...
Ethanol Conversion to Butanol over Small Coinage Metal Clusters: An Experimental and Computational Study
(Journal of Cluster Science, 2022-08-26)
We illustrate the mechanism for the C–O, C–H and O–H bond activation in the coupling of ethanol to butanol over small coinage clusters (copper, silver and gold). It is found that charge transfer interactions between the ...
Prevalence and diversity of Plasmodium species in pregnant women attending antenatal clinics in selected health centers of Kakamega County, Western Kenya
(Scientific African, 2022-10-11)
Malaria remains a major public health concern around the world with tropical and sub-tropical regions bearing the greatest brunt despite up-scaling of control strategies. Despite the provisioning of insecticidal nets to ...
Rhizobia Contribute to Salinity Tolerance in Common Beans (Phaseolus vulgaris L.)
(Cell, 2022-11-16)
Rhizobia are soil bacteria that induce nodule formation on leguminous plants. In the nodules, they reduce dinitrogen to ammonium that can be utilized by plants. Besides nitrogen fixation, rhizobia have other symbiotic ...
Phytochemical, Cytotoxicity, and Antimycobacterial Activity Evaluation of Extracts and Compounds from the Stem Bark of Albizia coriaria Welw ex. Oliver
(Evidence-Based Complementary and Alternative Medicine, 2022-01-22)
ackground. Albizia coriaria Welw ex. Oliver (Fabaceae) is one of the plants used by herbalists in the East Africa community to prepare herbal remedies for the management of symptoms of TB. Despite its widespread use, the ...
An Analysis of Knowledge, Attitudes and Practices of Communities in Lake Victoria, Kenya on Microcystin Toxicity
(Open Journal of Ecology, 2022-03-03)
Exposure to microcystin poses a potential health hazard to humans and other living organisms. This results from eutrophication and warrants an investigation into the problem of microcystin toxicity in Lake Victoria. This ...
Travelling Wave Analysis of a Diffusive COVID-19 Model
(HINDAWI: Journal of Applied Mathematics, 2022-10-07)
In this paper, a mathematical model based on a system of nonlinear parabolic partial differential equations is developed to investigate the effect of human mobility on the dynamics of coronavirus 2019 (COVID-19) disease. ...
EFFECT OF INQUIRY-BASED LEARNING ON STUDENTS’ ATTITUDE TOWARDS LEARNING BIOLOGY AT UPPER SECONDARY SCHOOLS IN RWANDA
(Journal of Baltic Science Education, 2022-10)
Attitude has been regarded as a motivating feeling for the learning of biology. However, how inquiry-based learning contributes to attitude change towards the learning of biology has not yet been studied in Rwanda. This ...
