(NM-AIST, 2022-08)Fall armyworm (FAW-Spodoptera frugiperda), a highly destructive and fast spreading agricul tural pest native to North and South America, poses a real threat to global food security. It is estimated that intermittent FAW ... -
Mathematical modeling of the effect of seasonal weather variations on the dynamics of plague disease
(NM-AIST, 2019-02)A mathematical model to study the effect of seasonal weather variation on the dynamics of plague disease is developed and analyzed. Apart from being historical, plague disease caused by a gram negative bacteria called ... -
Mathematical modelling and analysis of deformable perturbed continuously stirred tank reactors (cstrs)
(NM-AIST, 2022-07)In this dissertation, deterministic and stochastic mathematical models for a deformable per turbed continuously stirred tank reactor (CSTR) with exothermic and endothermic reactions have been developed and analysed. The ... -
Mathematical Modelling of Intra and Inter Dynamics and Control of Yellow Fever in Primate and Humna Populations
(The Nelson Mandela African Institution of Science and Technology, 2016)A deterministic mathematical model was formulated using non-linear ordinary differential equations to gain an insight of dynamics of yellow fever (YF) between primates, human beings and Aedes mosquito for the purpose of ... -
Mathematical models for the dynamics of health related risks associated with alcoholism and its control strategy in Tanzania
(NM-AIST, 2021-08)Alcoholic behavior has continually posed health challenges in many communities for decades. Referring to Tanzanian situation, this study presents a more realistic model for the dynamics of health risks associated with ... -

(NM-AIST, 2021-06)Brucellosis is a contagious zoonotic infection caused by Gram-negative bacteria of family Bru cellaceae and genus Brucella that affects humans and animals. The disease is of economic sig nificance, veterinary interest and ... -
Mathematical models of trypanosoma brucei rhodesiense disease transmission and control strategies
(NM-AIST, 2021-06)Human African Trypanosomiasis (HAT), also known as sleeping sickness is a neglected dis ease that impacts 70 million people living in 1.55 million km2 in sub-Saharan Africa. The disease strikes predominantly poor populations ... -
Modeling the dynamics, control and economic loss of newcastle disease in village chicken: a case of Pwani region in Tanzania
(2019-03)Newcastle disease (ND) is a highly contagious viral bird disease affecting the domestic and other wild birds. The disease is a major threat to the farming of village chicken by small, medium, and large scale farmers. In ... -
Modelling the transmission dynamics and control of taeniasis and cysticercosis in humans, pigs and cattle
(NM-AIST, 2022-08)Taeniasis and cysticercosis are neglected food-borne diseases that pose challenges to food safety, human health and livelihood of rural livestock farmers. Cysticercosis reduces the market value for pigs and cattle by ... -
Modelling wildebeest foraging processes and their interaction with zebra and lion in the Serengeti ecosystem
(NM-AIST, 2022-06)Animal movements and foraging processes for the migrating species, especially wildebeests and zebras, and the prey-predator interactions of these prey species with lions are ambiguous biological characteristics in the ... -
Momputational analysis of MHD blood flow through a stenosed artery in the presence of body acceleration and chemical reaction
(NM-AIST, 2021-10)The unsteady, laminar and two-dimensional pulsatile flow of both, Newtonian and non Newtonian chemically reacting blood in an axisymmetric stenosed artery subject to body ac celeration and magnetic fields were studied. In ... -
Monitoring of the grain crops in storage facilities through wireless communication technology
(NM-AIST, 2018-09)The storage condition measurement of grain crops is almost non-invasive to date; most of the technologies can be used to monitor the storage. Electromagnetic radiation is still popular wireless technique for grain storage ... -
A Monitoring System for Transboundary Foot and Mouth Disease (FMD) considering the Demographic Characteristics in Gairo, Tanzania
