A deterministic model for the transmission dynamics of a communicable disease is developed and rigorously analysed. The model, consisting five mutually exclusive compartments representing human dynamics, has globally asymptotically stable disease-free equilibrium (DFE) whenever certain epidemiological threshold, known as basic reproduction number (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
A deterministic model for the transmission dynamics of measles in a population with fraction vaccinated individuals is designed and rigorously analyzed. The standard incidence exhibits phenomenon backward bifurcation, where stable disease‐free equilibrium coexists endemic whenever associated reproduction number less than unity. This can be removed if either vaccine assumed to perfect or disease related mortality rates are negligible. In latter case, shown globally asymptotically Furthermore,...
Abstract A deterministic model for the transmission dynamics of two strains dengue disease is presented. The model, consisting mutually exclusive epidemiological compartments representing human and vector dynamics, has a locally asymptotically stable, disease-free equilibrium whenever maximum associated reproduction numbers less than unity. can have infinitely many co-existence equilibria if infection with one strain confers complete cross-immunity against other number each exceeds On hand,...
This study was conducted to investigate in vivo antimicrobial potential of garlic against Clostridium perferinges and resultant promotant effects on performance the broiler chickens. Garlic powder used as an alternative GPAs (Growth Promotant Antibiotics) prevent subclinical Necrotic Enteritis (NE) due C. perferinges. 120 day-old chicks were randomly distributed six treatment groups 20 each (2 replicates(-10) chicks). Six isonutrient diets supplemented with at graded levels 0.0, 0.5, 1.0,...
AbstractA new deterministic mathematical model for the transmission dynamics of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is proposed and fully analyzed. The presented exhibits a unique endemic equilibrium there no infection free due to constant influx latent immigrants. An invasion threshold parameter derived stability analysis full its two special cases carried out. impact quarantine isolation assessed via approach, while immigration on disease prevalence discussed. Indeed,...
Industrial and nutritional processes have increased the demands for oil this in turn has led to search oils from different types of seeds. It is vein that baobab seed was extracted, analyzed some it physicochemical properties compared with those vegetable, peanut palm oils. The percentage yield, iodine value, acid peroxide moisture, free fatty acids gossypol content were determined. results show quality comparable commercial great industrial potentials. therefore recommended more research be...
A new model for the transmission dynamics of Mycobacterium tuberculosis and bovine in a community, consisting humans African buffalos, is presented. The buffalo-only component exhibits phenomenon backward bifurcation, which arises due to reinfection exposed recovered when associated reproduction number less than unity. This has unique endemic equilibrium, globally asymptotically stable special case, exceeds Uncertainty sensitivity analyses, using data relevant two diseases Kruger National...
A deterministic model for the transmission dynamics of Zika, that takes into account aquatic and non-aquatic stages mosquito development is constructed rigorously analysed. The with fraction male mosquitoes being sterilized assumed direct (human-human) indirect (human-mosquito-human) transmission. Stability analysis equilibria sensitivity parameters associated computed reproduction number were presented. Numerical simulation carried out to support analysis.
In this study, a non-autonomous (temperature dependent) and autonomous independent) models for the transmission dynamics of malaria in population are designed rigorously analysed. The used to assess impact temperature changes on various control strategies. model is shown exhibit phenomenon backward bifurcation, where an asymptotically-stable disease-free equilibrium (DFE) co-exists with endemic when associated reproduction number less than unity. This arise due presence imperfect vaccines...
A study was carried out on the morphometry of reproductive genitalia 45 African Zebu cattle (AZC) using standard laboratory procedure, with special reference to heifers and cows. The overall mean weight cows were 0.43 + 0.03 kg 0.79 0.02 respectively. ovarian weights heifer from left right 3.80 0.12g 4.88 0.04g; that 3.53 0.10g 5.48 0.04g respectively. length cow oviduct 30.04 0.08 cm 30.21 0.07 cm; 21.68 0.18 22.14 0.16 There no significant difference in diameter between (P > 0.05). ...
Thirty two intact male goats representing eight replicates of breeds (Sokoto Red Versus Sahel) and ages (Young Mature) were investigated for linear body measurements conformational traits. All had higher values (P<0.05) in the Sahel except chest girth, width depth, which did not differ significantly between breeds. Mature all than young goats. carcass also mature traits; slaughter weight, Body mass index (BMI) empty weight traits BMI where Sokoto was superior (46.20 versus 41.45). It...
A deterministic model for the transmission dynamics of Zika is designed and rigorously analysed. consisting mutually exclusive compartments representing human mosquito takes into account both direct (human‐human) indirect modes transmissions. The basic offspring number population computed condition existence stability equilibria investigated. Using centre manifold theory, (with without transmission) shown to exhibit phenomenon backward bifurcation (where a locally asymptotically stable...
This study was designed to determine the effects of Garlic and Neem leaf aqueous extracts on their individual basis and/ or mixture humoral immune response broilers against NDV (Newcastle Disease Virus) Vaccine. One hundred sixty day old broiler chicks were randomly allocated into four groups A, B, C D. All birds raised in cages beneath same house operating under conventional deep litter system. Group A regarded as control received neither extracts. D treated with 5g Garlic, a 2.5g...
