In this paper, we challenge Jeffrey Beall’s still dominant in the psyche approach to journal classification and some other ill-conceived approaches to journal classification, and attempt to show why such reductionist views are harmful to the healthy growth of science. While scientific fraud in any form must be horsewhipped and must not be exonerated or absolved at any cost and under any circumstances, journal classification and all other attendant issues and factors impacting and affecting ...
Abstract: Background Novel malaria vector control approaches aim to combine tools for maximum protection. This study aimed to evaluate novel and re-evaluate existing putative repellent ‘push’ and attractive ‘pull’ components for manipulating the odour orientation of malaria vectors in the peri-domestic space. Methods Anopheles arabiensis outdoor human landing catches and trap comparisons were implemented in large semi-field systems to (i) test the efficacy of Citriodiol® or transflu...
This paper, which is perhaps our umpteenth and umptieth on scientific method and scientific methodology, proposes, discusses and lays bare the canon of what we propose to call “irreducible simplicity”. We believe and hypothesize that this approach would encompass, and play a natural, pivotal and a vital role in all aspects and facets of scientific activity from the cradle to the grave such as grounds-up hypothesis conceptualization, hypothesis building, detailed hypothesis specification, ...
Abstract: A quantitative study of the swelling capacity of polymer-oligomer particles, and the rate of transport of slightly water soluble compound 1, e.g. chlorobenzene, from bulk phase to the particles has been carried out. A much higher swelling capacity was attained when compound 1 was subdivided (before it was added to the swelling experiments) than when it was added as a bulk at the same experimental conditions. It is shown that the increased swelling capacity when compound 1 is subdiv...
The effect of a fire disaster is greater in developing countries due to inadequate 'firefighting preventive and support systems. There is therefore the need to analyze fire incident data to enable better fire safety and prevention strategies. The study was a retrospective cross-sectional study from January to June 2021. In all, 130 fire incident reports from 2017 to 2020 were collected. The data, consisting of 32 variables were analyzed using binary logistic regression. It was observed that f...
https://doi.org/10.1016/j.ceramint.2023.01.063._ In this study, unique hybrid structures were constructed between a Ce-based metal-organic framework (Ce-MOF) and and graphitic carbon nitride (g-C3N4) materials. In addition, the g-C3N4 materials used for these heterostructures were prepared by five different methods, namely the conventional pyrolysis method, chemical exfoliation by a strong acid, activation by an alkaline hydrothermal treatment, melamine-cyanuric acid supramolecular assembly w...
A method to create smart and flexible switches for the regulation of liquid flow across multiple channels is essential in paper microfluidics. Prior approaches are hampered by long response times, high actuation fluid volumes, and external control circuitry. To diminish these problems, we designed a distinctive actuator device fashioned entirely from chromatography paper and featuring folds. The fold can be selectively wetted by an actuation fluid at either the crest or trough, resulting in t...

Abstract The study is to identify the presence of phytochemical composition, proximate composition and mineral composition of the fruit, leave, bark and root of Africa Black Velvet Tamarind (dialium guineense). It is aimed at investigating the nutritionall constituenrs of the fruit, leave, bark and root of Africa Black Velvet tamarind. The crude extract were obtained and were screened for the presence of Phytochemicals, in order to identify the therapeutic potential of the plant. The result ...
ABSTRACT:Water is a basic natural resource that sustains life and economic development. It is the next resource to air. Water can exist in various forms that is gaseous, solid and liquid. A study on the implication of water scarcity on the environment was conducted in Kisarawe village, Kisarawe District.In order to investigate the above, the following variables were measured; water sources, distribution systems, associated problems and measures being used to mini...
ABSTRACTThis research study aimed at assessing the effectiveness of Moringa oleifera coagulant in thetreatment of safer, cleaner, adequate and cheaper drinking water for all Ugandans. Watersamples from Lake Victoria and hand dug wells both found in Ggaba were treated using Moringa oleifera and Alum coagulant in different sets according to ISO 9308 1-1 and Associationof Official Analytical Chemist (AOAC) jar test procedures. Then pH, turbidity, conductivityand total coliform levels of water sa...
ABSTRACT Thaumatococcus daniellii and Musa acuminate are leaves used for wrapping foods and these herbs have some medicinal value. The affordability, preservation, usage techniques, and seasonal scarcity of the leaves make it difficult for people to use them frequently but they are preferred over plastic bags and aluminum foil in terms of wrapping edible foods like beans pudding (moi-moi), agidi, etc and fresh foods like uncooked meat, vegetables etc. This research work involved phytochemica...
ABSTRACT In this study, gravity survey method was used to investigate the geothermal potential field in Gilgil area, Nakuru County, Kenya. No previous geophysical study has been done in Gilgil area. Gilgil area is volcanic and gravity survey in volcanic regions has shown that it gives useful information about the density changes within the Earth’s subsurface associated with the heat source. Gravity highs are related to centres of volcanism, faults and geothermal activity. The discovery of g...
ABSTRACT Primordial radionuclides in building materials are one of the major sources of radiation hazard in dwellings. Clay bricks are mainly used for the construction of dwellings in Bomet district, Bomet County, Kenya. Therefore, knowledge of the presence of natural radioactivity in these materials is of great importance in order to assess the radiological hazards associated with them. In this context, specific activities of 226Ra, 232Th and 40K were measured in brick samples collected from...
