Efficacy of Metarhizium anisopliae against the Greater Pumpkin Fly Dacus bivitattus
(UoEm, 2023-07-01)The greater pumpkin fly Dacus bivittatus (Bigot) is a fruit fly indigenous to Africa, which causes extensive damage to Cucurbitaceae. To control this pest, farmers rely on synthetic chemicals, often organophosphates, which ... -
A Guide for Soil Health and Fertility for Maize production in Kenya
(UoEm, 2023)The health of your soil is a fundamental aspect of successful farming. However, many arable soils in Kenya have degraded and lost fertility over recent decades1. This is expected because many soils were recently transformed ... -
Mathematical Modelling of Drug Abuse, Unemployment and Mental Stress on Population Dynamics of Mental Ilness
(UoEm, 2024-01)There has been a rise in the number of reported cases of mental illness in both High Income Countries (HICs) and Low and Middle Income Countries (LMICs). Non-communicable Diseases (NCDs) seldom make use of mathematical ... -
Fiscal Deficit Financing and Inflation in Sub-Saharan Africa
(UoEm, 2023-12)Financing fiscal deficit in any country is undertaken with the sole purpose of promoting economic growth and development. However, fiscal deficit financing can be a major source of macroeconomic instability, especially ... -
Real Estate Development, Human Capital and Economic Growth in Kenya
(UoEm, 2023-12)Having a stable and high level of economic growth within a country is associated with numerous benefits to the citizens. In developing countries such as Kenya, the rate of economic growth has been low and always below the ... -
Qualification of Greenhouse Gas Fluxes from Selected Cropping Systems under on Farm Conditions in Tharaka-Nithi, Kenya
(UoEm, 2024-03)The smallholder cropping systems have an adverse effect on greenhouse gas (GHG) emissions to the ecosystems due to varied contribution to the GHG budgets. Further, the uncertainty on the contribution of an individual ... -
Parental Involvement Influence on Education Participation for Learners with Hearing Impairments in Special Public Primary Schools in Meru and Isiolo Counties- Kenya
(UoEm, 2024-05)Globally need for education, as a measure of one's ability to function fully in today's society, is an important motivator for efforts to achieve the highest level of education in the world. The persistent under achievement ... -
Competition, Profitability, Risk-Taking Behaviour and Stability of Commercial Banks in Kenya
(UoEm, 2023-08)Stable commercial banks stimulate economic growth by facilitating value exchanges. The stability of commercial banks in Kenya has been a concern because of the waves of collapse that have dotted the history of the ... -
Identification of Elsinoë phaseoli causing bean scab in Kenya and evaluation of sporulation using five adapted techniques
(UoEm, 2024-06-07)This research addresses the presence of Elsinoë phaseoli in Kenya, where information on the biology of this pathogen remains scarce. Employing a multifaceted approach, the study demonstrates the steps taken to isolate, ... -

Modelling and Simulation of Competition for Students’ Population with Holling Type II Response
(UoEm, 2023)Te increase in the country’s population attracted the establishment of more schools, both public and private schools, to cater for the increasing number of students. However, there have been dynamics of students’ population ... -
Transitivity Action of An on (n=4,5,6,7) on Unordered and Ordered Quadrupples
(UoEm, 2015)In this paper, we study some transitivity action properties of the alternating group An(n=4,5,6,7 ,) acting on unordered and ordered pairs from the set X = {1,2,...,n} through determination of the number of disjoint equivalence ... -
Rank and Subdegrees of P GL(2, q) Acting Cosets of P GL(2, e) for q an Even Power of e
(UoEm, 2019)The action of projective general group on the cosets of its maximal subgroups has been studied. For instance, [9] studied the action of G on the cosets of P GL(2, e) when q is an odd prime power of e. In this paper, we ... -
Predicting the Number of Tourists in-Flow to Kenya Using Seasonal Autoregressive Integrated Moving Average Model
(UoEm, 2022-12)Tourism is the leading source of revenue to the Kenyan Government, contributing about 8.8% to the Kenya’s Gross Domestic Product. Based on the 2019 report released by the ministry of tourism and wildlife, tourism industry ... -
On the Number of Cyclotomic Cosets and Cyclic Codes over Z13
(UoEm, 2018-06)Let Zq be a finite field with q element and x n − 1 be a given cyclotomic polynomial. The number of cyclotomic cosets and cyclic codes has not been done in general. Although for different values of q the polynomial x n ... -
Enumeration of cyclic codes over GF(17)
(UoEm, 2015-05)In this paper we seek the number of irreducible polynomials of xn− 1 over GF(17). We factorize Xn− 1 over GF(17)into irreducible polynomials using cyclotomic cosets of 17 modulo n . The number of irreducible polynomials ... -
Cycle Index Formulas for Dn Acting on Ordered pairs
(UoEm, 2016-04)The cycle index of dihedral group Dn acting on the set of the vertices of a regular n-gon was studied by Harary and Palmer in 1973 [1]. Since then a number of researchers have studied the cycle indices dihedral group ... -
Cycle Index Formulas for Dn Acting on Unordered Pairs
(UoEm, 2015)The cycle index of dihedral group Dn acting on the set X of the vertices of a regular -gon was studied (See [1]). In this paper we study the cycle index formulas of Dn acting on unordered pairs from the set x . In ... -
Action ofPGL (2 ,q ) on the Cosets of the Centralizer of an Eliptic Element
(UoEm, 2021)Most researchers consider the action of projective general group on the cosets of its maximal subgroups leaving out non-maximal subgroupsCq+1. In this paper, we consider the action ofPGL (2, ) centralizer of an elliptic ... -
Application of Marks to Computation of Ranks and Subdegrees of the Symmetric Group Acting on Ordered 4-Element and 5- Element Subsets
(UoEm, 2015)Ranks and subdegrees can be computed using combinatorial arguments, the Cauchy-Frobenius lemma and use of the concept of marks. However the concept of Marks has been given very little attention. In this paper we will apply ...
