MODELLING THE DYNAMICS OF RADICALIZATION WITH GOVERNMENT INTERVENTION

Abstract ABSTRACT: Radicalization is the process by which people come to adopt in- creasingly extreme political, social or religious ideologies. When radicalization leads to violence, radical thinking becomes a threat to national and international security. Prevention programs are part of an effort to combat violent extremism and terrorism. This type of initiative seek to prevent radicalization process from occurring and tak- ing hold in the first place. In this paper we introduce a simple c...

Genetic Characterization of Rhizosphere Bacteria that Inhabit Common Bean Nodules in Western Kenya Soils

Abstract Background: With the increasing world population, there is increasing demand for food. This has led to overuse of agricultural farms causing reduced soil fertility and accumulation of phytopathogens. Inorganic fertilizers and pesticides have been extensively used in response to these challenges. Extensive integration of inorganic fertilizers and pesticides in the farming system has contributed to soil and water pollution worsening the eutrophication in rivers lake waters. Alternativ...

Fish Tissue Bio-concentration and Interspecies Uptake of Heavy Metals from Waste Water Lagoons

Abstract Fish products may be important vectors of human exposure to heavy metals. However the understanding of how heavy metals bioconcentrate in different fish species (sp.) through contaminated environments such as wastewater treatment lagoons is very limited. In this study bioconcentration and Interspecies Uptake of Heavy Metals by three fish species (Oreochromis niloticus, Clarius gariespinus and Protopterus aethiopicus) receiving naturally contaminated wastewater was investigated. Tiss...

Stability and Kinetics Studies Using an RP- HPLC-UV Method Developed for Assays of Salvianolic Acid A Degradation as a Therapeutic

Abstract Aims: To evaluate the stability of Salvianolic acid A (SAA), a promising cardiovascular drug candidate. Additionally avail an archetype in-vitro therapeutic monitoring from SAA degradation profile for characteristic oral gavages. Study Design: Experimental by laboratory analysis. Place and Duration of Study: Department of Chemistry & Biochemistry, Moi University; Department of Pure & Applied Chemistry and Department of Medical Laboratory Sciences of Masinde Muliro University of Scie...

Phytochemical Screening and Antimicrobial Activity of Kenyan Mushroom Ganoderma lucidum

Abstract Aim: To screen the Kenyan Ganoderma lucidum for phytochemicals and to investigate it's potential in the management of some disease-causing microbes. Study Design: Hexane, ethyl acetate and methanol extraction; phytochemical study and anti-microbial activities were analysed on Kenyan G. lucidum mushroom. Place and Duration of Study: Masinde Muliro University Science laboratories from January 2019 and March 2019. Methodology: Sequential extraction of dried samples was done using hexan...

Effect of Surface Passivation on Electrical Properties of Pd-F:SnO2 Thin Films Prepared by Spray Pyrolysis Technique

Abstract Pd-F:SnO2 thin films have been prepared by spray pyrolysis technique. Optimization has been done by doping SnO2 with palladium at varying levels of concentration and then recording sheet resistance. The sheet resistivity has been observed to decrease gradually as at% Pd concentration is increased; an optimum sheet resistivity value of 2.71 × 10−2 Ω cm has been recorded. The decrease in sheet resistivity has been attributed to presence of Pd ions which contribute in increment of...

On A Class of Idealized Near-Rings Admitting Frobenius Derivations.

Abstract In this paper, we use the idealization procedure for finite rings to construct a class of quasi-3 prime Near-Rings N with a Jordan ideal J(N) and admitting a Frobenius derivation. The structural characterization of N; J(N) and commutation of N via the Frobenius derivations have been explicitly determined.

Intervention Time Series Modeling of Infant Mortality: Impact of Free Maternal Health Care

Abstract Infant mortality is an important marker of the overall society health. The 3rd goal of the Sustainable Development Goals aims at reducing infant deaths that occur due to preventable causes by 2030. Due to increased infant mortality the Kenyan government introduced Free Maternal Health Care as an intervention towards reducing infant mortality through elimination of the cost burden of accessing medical care by the mother and the infant. The study examines the impact of Free Maternal H...

An Analysis of Knowledge, Attitudes and Practices of Communities in Lake Victoria, Kenya on Microcystin Toxicity

Abstract 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 study was conducted in Homa Bay, Kisumu, Siaya and Busia counties to understand the effects of microcystin toxicity among fisherfolk and lake riparian communities. Data collection involved 90 semi-structured questionnaires, 11 key informant interviews and seven focu...

Nurturing Ubuntu, the African Form of Human Flourishing Through Inclusive Home Based Early Childhood Education

Abstract Human flourishing has recently gained more attention in the world as a prerequisite safety net for better human resilience in uncertain times. While most Western authors believe that human flourishing is an individual issue, gained in later life, African communities that are largely communal may not have the same view. Communalism as opposed to individualism as a key pillar in African Ubuntu thinking makes it a possibility that there is a departure in the contextualisation of human ...

Mathematical Modelling and Analysis of Corruption of Morals amongst Adolescents with Control Measures in Kenya

Abstract In the present paper, we formulate a new mathematical model for the dynamics of moral corruption with comprehensive age-appropriate sexual information and provision of guidance and counselling. The population is subdivided into three (3) different compartments according to their level of information on sexual matters. The model is proved to be both epidemiologically and mathematically well posed. The existence of unique morally corrupt-free and endemic equilibrium points is investig...

The Beauty of Mathematics: Learning Mathematics by Questioning

Abstract Mathematics problems may seem to have no real use in life, but this could be further from the truth. The use of mathematics is everywhere in our daily lives and, without discovering it; we apply mathematics ideas, as well as the skills we learn from executing mathematical challenges every day. Unfortunately, mathematics feedback at national examinations is deficient. A mean of between 23 to 29 percent for 5 years in a row from 2014 to 2018 is a clear indication that the training of ...

Mathematical Modeling and Analysis of Mathematics Anxiety Behavior on Mathematics Performance in Kenya

Abstract We propose a deterministic model that describes the dynamics of students who have the capabilityWe propose a deterministic model that describes the dynamics of students who have the capabilityto perform well in mathematics examinations and engage in careers that demand its applicationand the negative inuence of individuals with mathematics anxiety on the potential students.Our model is based on SIR classical infectious model classes with Susceptible (S) and Infected (I)taken as Math...

Stability Analysis in a Mathematical Model of Corruption in Kenya

Abstract The term corruption refers to the process that involves the abuse of a public trust or office for some private benet. Corruption becomes a threat to national development and growth especially when there is no political will to fight it. Prevention and disengagement initiatives are part of EACC strategies used to fight corruption. Prevention strategies aim to stop or discourage citizens from engaging in corruption. Disengagement strategies attempt to reform corrupt individuals and to...

In Silico Identification of New Anti-SARS-CoV-2 Main Protease (Mpro) Molecules with Pharmacokinetic Properties from Natural Sources Using Molecular Dynamics (MD) Simulations and Hierarchical

Abstract Infectious agents such as SARS-CoV, MERS-CoV, and SARS-CoV-2 have emerged in recent years causing epidemics with high mortality rates. The quick development of novel therapeutic compounds is required in the fight against such pathogenic agents. Unfortunately, the traditional drug development methods are time-consuming and expensive. In this study, computational algorithms were utilized for virtual screening of a library of natural compounds in the ZINC database for their affinity to...
