Diffusivity Of Chloride And Sulphate Ions Into Mortar Cubes Made Using Ordinary Portland And Portland Pozzolana Cements

ABSTRACTCement is subject to degradation by aggressive media found in the environment. Durability tests are therefore necessary for any cementitious material in a given aggressive environment. This study investigated chloride and sulphate diffusivity in mortar made from selected Kenyan cements. The test cements included three brands of Ordinary Portland Cements (OPC) and three brands of Portland Pozzolana Cements (PPC). The test cements were used to make mortar prisms at different water / cem...

Repellence Of Essential Oil Of Nigella Sativa L. Seeds Against Anopheles Gambiae And Identification Of The Active Blend

ABSTRACTAnopheles gambiae mosquitoes are vectors of malaria because of their ability to transmit Plasmodium falciparum parasites. The major impact of malaria is in sub-Saharan Africa where at least 90% of the deaths from malaria occur. In Kenya, malaria accounts for 30% of all outpatients and 19% of all admissions to health facilities. Malaria can also affect the quality of labour negatively and also can lead to low productivity through absenteeism. Anopheles gambiae is the vector associated ...

The Spectrum Of Bacteria Causing Urinary Tract Infection Among Pregnant Women Attending Sabasaba Clinic And Their Susceptibility To Antimicrobial Agents

ABSTRACT Urinary tract infections (UTI) during pregnancy can lead to serious obstetric complications, poor maternal and perinatal outcomes. The purpose of this study was to determinethe prevalence of bacterial UTI in pregnant women in Morogoro municipality, Tanzania. This study was conducted at SabaSaba Health Centre from May 2014 to July 2014 involving 196 pregnant women. Mid stream of urine samples were obtained and analyzed by dipstick and processed for culture. Out of 196 pregnant ...

Food Additives And Hygienic Status Of Flavoured Fruit Juices Manufactured In Dar Es Salaam, Tanzania

ABSTRACT The purpose of this study was to assess the quality of juices manufactured and sold for immediate consumption in Dar es Salaam Municipalities, Tanzania. The assessments were based on identifying the levels of preservatives, hygienic practices in manufacturing industries and determine microbiological quality of the juices. High Performance Liquid Chromatographic (HPLC) method was modified and validated for determination of benzoic and sorbic acids, while direct titration met...

Epidemiological Study Of Infectious Bursal Disease Virus In Selected Districts Of The Copperbelt Province In Zambia

ABSTRACT Infectious bursal disease (IBD) is a highly contagious disease of young chickens between 3 and 6 weeks of age. It is caused by infectious bursal disease virus(IBDV) which occursworldwide affecting livelihoods of resource - compromised poor communities. In Zambia, there is scantily documented information on the epidemiology of IBD. In-depth knowledge on the epidemiology of IBD is needed for effective control measures. This study aimed at molecular detection of circulating IBDV s...

Isolation, Identification And Antibiogram Of Salmonella Enterica From Chicken Eggs Collected From Selected Wards In Morogoro Municipality, Tanzania

ABSTRACTEggs provide protein to human. However, consumption of contaminated eggs with pathogenic Salmonellae (Salmonella enterica) imposes negative impacts to human health causing salmonellosis. The present study aimed at isolation, identification and antibiogram testing of Salmonella enterica from chicken eggs in Morogoro Municipality. A total of 570 raw, boiled, cracked, clean, and faecal soaked chicken eggs (120 local and 450 exotic) were collected from selected areas and examined from Nov...

Bacterial Contaminants Of African Indigenous Leafy Vegetables And Their Antibiotics Sensitivity Characteristics: A Case Study Of Morogoro Municipality, Tanzania

ABSTRACTA study was conducted in Morogoro Municipality, Tanzania to investigate the bacterial load found on African indigenous leafy vegetables, their sources and their sensitivity to commonly used antibiotics. A total of 126 samples of fresh African indigenous leafy vegetables (amaranth, nightshade and sweet potato leaves), water used for irrigation from rivers and shallow wells and manure fertilised soils were collected at farm sites and market outlets for bacteriological analysis. Bacteria...

Prevalence And Related Risk Factors Of Porcine Cysticercosis And African Swine Fever In Selected Urban/Peri-Urban Areas Of Morogoro, Tanzania

ABSTRACTThis study was carried out to estimate the prevalence and related risk factors of porcinecysticercosis (caused by Taenia solium) and African swine fever (ASF) in domestic pigs,and assesses the state of pork inspection in urban/peri-urban areas of Morogoro region,Tanzania, between November 2010 and January 2011. A two stage random sampling wasemployed. A total of 260 live pigs were tested serologically. Serum samples were testedfor the presence of circulating parasite antigen using a m...

Investigating The Perfomance Of Lateral Flow Devices In Diagnosis And Genetic Characterization Of Foot And Mouth Disease Virus In Tanzania

ABSTRACTA study on rapid detection and diagnosis of foot and mouth disease (FMD) field outbreaks was carried out in field settings using a Svanodip® foot and mouth disease virus (FMDV)- antigen (Ag) test lateral flow device (LFD) in Serengeti and Ngorongoro districts of Tanzania. Epithelial tissues from cattle (n=80) were collected from different villages and tested at penside using Svanodip® FMDV-antigen test to evaluate the sensitivity and specificity of LFDs relative to gold standard rev...

Diversity And Biological Control Potential Of Haloalkaliphilic Fungi From Lake Magadi, Kenya

ABSTRACTFungi are eukaryotic microorganisms that have simple multicellular or unicellular cell structures. They are distributed in terrestrial soils, forests, aquatic habitats and in extreme environments with high ambient salts, temperature, pH and pressure. Fungi from extreme environments are potential sources of novel biocatalysts for example antimicrobial agents that can help solve the rising cases of drug resistance. However, the diversity of fungi recovered and described from less studie...

Occurence And Distribution Of Pathogenic Viruses And Fungi In Sweet Potato Varieties In Gweru

ABSTRACTViruses and fungi are the major threat to sweet potato production because they reduce yield by up to 90% thereby threatening food security. A study was carried out to identify pathogenic viruses and fungi affecting sweet potato and to determine their distribution across varieties and sites in Gweru. A total of 28 samples belonging to five different sweet potato varieties were collected from nine sites in Gweru. Plants were screened for viruses using two methods namely direct observati...

Semigroups Of Linear Operators And Application To Differential Equations

This work concerns one of the most important tools to solve well-posed problems in the theory of evolution equations (e.g diusion equation, wave equations, ...) and in the theory of stochastic process, namely the semigroups of linear operators with application to dierential equations.

Studies On Yersiniosis In Human And Selected Animal Populations In Jos And Its Environs

ABSTRACTYersinia enterocolitica and Yersinia pseudotuberculosis are important food and water borne pathogens that has recently emerged world wide. This study was aimed at characterizing the prevalence of Yersinia enterocolitica and Yersinia pseudotuberculosis in human and selected animal populations in Jos and its environment. Three thousand stool samples from human and selected animal species from 5 different locations in Jos and its environs were surveyed over a period of three years. Human...

Epidemological Studies on Some Microbial And Parasitic Infectious of Nomadic Fulani Herdsmen in Ebonyi State, Nigeria

Abstract Over the years, nomadic Fulani herdsmen have established different settlement camps outside the traditional villages of their indigenous host communities in Ebonyi State.
