Seroprevalence And Genetic Characterisationof Peste Des Petitsruminants Virus In Selected Areas Of Tanzania

ABSTRACTPeste des petits ruminants (PPR) is an acute, contagious, fatal disease of domestic and wild small ruminants caused by PPR virus (PPRV). A cross-sectional study was conducted to (i) detect PPRV infection, establish the viral lineage and identify the possible source of its introduction and spread in Morogoro district between November 2014 and January 2015 and (ii) determine presence of PPR in selected villages of Ngorongoro district. Clinical samples of six goats from Morogoro urban an...

Effects Of Enzyme Maceration On Physicochemical Properties And Micronutrient Bioaccessibility Of Strychnos Cocculoides Products (Juice/Porridge)

ABSTRACTInformation on the nutritional content and health-promoting properties of African indigenous fruits is very limited. Although the limited available literature does point towards wealth in essential nutrients, micronutrients and antioxidants there is still a need to fill the gap to ascertain health and nutritional claims that have been passed on from previous generations. Studies on the impact of processing of the fruit pulp on physicochemical, nutritional properties, and digestibility...

Safe Miner Android Application

ABSTRACTDue to the current economic situation and the growth in world demand, the mining industry is undergoing a period of spectacular development. The current need to increase production at mine sites coincides with the development of managerial capacities, the use of new industrial methods and equipment, and increased use of skilled workforce. Despite such developments, a number of researchers view the mining sector among the world’s most uncertain and hazardous industries. Therefore, th...

A Bio-Immunology Inspired Security Model to Defend Industrial Control Systems from Advanced Persistent Threats

ABSTRACTIndustrial Control Systems (ICS) control critical industrial processes. For example, there are ICS networks that control electricity, water distribution, food, and pharmaceutical and beverage production. Historically, ICS networks were safe from network attacks because they were not interconnected to business Information Technology (IT) networks and the Internet. However, with the passage of time, ICS were interconnected to business networks. Because traditional IT networks are built ...

Cockroaches As Vectors Of Bacteria In Hospital Environments

ABSTRACTCockroaches have become one of the most common pests due to their wide distribution in human dwellings, kitchens, food outlets and the hospital. In hospitals their wide abundancy may be related to poor sanitary conditions, plenty of food sources, environments which are unhygienic and moist shady places. This study was carried out to evaluate the microbial fauna of cockroaches in a hospital environment as proxy to Health acquired infections. Two different species of cockroaches Peripla...

A Persuasive Souvenir System (Pss) To Increase Namibian Museums Turnout Using Rfid Technology

AbstractAn advance in information technology has seen many museums in the world embarking on extensive and continuous developments that can be used to improve visitor experience. The extensive and continuous developments are done by creating an interactive environment that attracts more visitors to museums and sustains their role of imparting knowledge and cultural education (Busch & Sieck, 2015). There are abundant possibilities in addressing low museum turnout. The possibilities range from ...

Big Data Analytics Framework for Agriculture

AbstractFarming is undergoing a digital revolution. Farmers are gathering information passively collectedby precision agricultural equipment and manually and many farmers are using information fromlarge datasets and precision analytics to make on-farm decisions. Big data includes extremely largedata sets that may be analysed computationally to reveal patterns, trends, and associations,especially relating to human behaviour and interactions. The use of large information sets and thedigital too...

Effect Of Varieties And Drying Methods On Nutrient Content And Sensory Acceptability Of Proccessed Products From “Mamung’unya” (Benincasa Hispida).

ABSTRACT“Mamung’unya” (Benincasa hispida) is a seasonal fruit widely grown in Dodoma region. To distribute its availability throughout the year, there is a need to test different drying methods for preservation. The present study was carried out to assess the effect of drying methods on nutrient content and sensory acceptability of processed products from selected Benincasa hispida varieties available in Dodoma region. A total of 120 farmers were interviewed using a structured questionn...

Effectiveness Of Tomato Postharvest Processing Technologies By Boiling And Solar Drying For Small Scale Processing In Morogoro Region

ABSTRACTThis study determine effectiveness of tomato postharvest processing technologies byboiling and solar drying for small scale processing based on nutritional and sensoryquality. Tomato sample varieties Asira, Imara and Reogrande were collected from smallscale farmers in Morogoro region for tomato paste and powder development. Nutritionalquality was determined based on moisture, lycopene, ß-carotene and ascorbic acidcontents, titratable acidity and pH. Sensory properties were determined...

Mosquito Diversity And Virus Infectivity In Kinshasa, Democratic Republic Of Congo

ABSTRACTMosquito species distribution patterns and their ecology is gaining importance, because global climate changes are thought to lead to the emergence of mosquito-borne diseases; which are of considerable medical and veterinary importance because of their high morbidity and mortality. This study was conducted in five municipalities of Kinshasa to determine mosquito diversity, and arboviruses infection within. Mosquitoes were collected using BG-Sentinel traps, battery-powered aspirator fo...

To investigate the potential of Moringa oleifera leaf extract and broccoli (Brassica oleracea) leaf extract as Sodium sulphite replacers in preserving minced meat

ABSTRACTMinced meat is a nutritionally dense and highly perishable food, therefore there is need forpreserving it. Most artificial preservatives currently used to prevent food spoilage have beenreported to cause various health problems hence the need to use natural preservatives. Moringaoleifera and Brassica oleracea (broccoli) leaf extracts have proved their potential to be used asnatural preservatives. The main objective of this research was to determine the antimicrobialefficacy of Moringa...

Sero-Surveillance, Risk Factors And Molecular Diagnosis Of Peste Des Petits Ruminants Virus In South Kivu, Democratic Republic Of Congo

ABSTRACTPeste des petits ruminants (PPR) is an acute viral disease of small ruminants caused by PPR virus (PPRV). For many years, the disease was mainly confined to West and Central Africa but has now spread southwards to previously PPR-free countries. The disease was first reported in Democratic Republic of Congo (DRC) in 2012. The disease causes high morbidities of up to 100 % and mortality rates between 50 and 90% in domestic small ruminants (goats and sheep) leading to the socio economic ...

Polymorphisms Of Kappa-Casein And Beta-Lactoglobulin Genes And Their Association With Milk Fat And Protein Contents In Tanzanian Goats

ABSTRACTThis study was conducted to assess the polymorphisms of beta-lactoglobulin (-Lg) and kappa-casein (-Cn) genes and determine the effects of -Lg polymorphism on percentage of milk fat and protein contents in indigenous goat breeds found in Tanzania. Blood samples were collected from 22 - 24 unrelated animals for each breed. Genomic DNA was isolated from whole blood samples using Sepa gene extraction kit with some modifications. The -Lg and -Cn genes were amplified using P...
