ABSTRACT The objectives of this work were to study the quality and acceptability of new rice varieties (Oryza sativa L.). The rice varieties (TXD88, NERICA4, NERICA1, TXD85 and TXD306) were analyzed for rough rice quality indices, proximate composition, milling quality, cooking time, physicochemical properties and sensory evaluation. The rough rice quality indices were 5.96 – 14.62% (immature grains); 30.91 – 36.78g (1000 grains’ weight); 7.81 – 9.05mm (length) and 3.14 – 3.65 (leng...
ABSTRACT Human health depends on reliable access to safe drinking water, but in many developing countries there are problems of accessing it. This is mainly attributed to water pollution, poor infrastructure for potable water treatment and unhygienic practices in water bottling companies. This study was carried out to assess the physico-chemical and microbiological quality of borehole, bottled and municipal water in Harare (Zimbabwe), by evaluating the compliance of each water type with WHO s...
ABSTRACT Plants remain a major source of novel drugs for the treatment of various diseases like cancer. The search for safe anticancer drugs from plants has led to the discovery of camptothecin and taxol. Smilax kraussiana is used in herbal medicine to treat tumors, veneral and skin diseases. Many plants including S. kraussiana are still underexploited despite their ethnomedicinal properties. This study was designed to isolate and characterise the constituents of S. kraussiana, synthesise ac...
ABSTRACT One of the objectives of x-ray examination is high quality images; however administered radiation doses may be harmful to patients‟ health. Data on radiation dose to patients are scarce, and thus hinder the determination of local and national reference dose levels specific to a country owing to the differences in patient anatomy and radiological practice among nationals of different countries. This study was therefore, designed to determine the patient doses, local reference dose ...
Abstract Clay bodies occur as lenses and interbeds within the predominantly shaley Akinbo Formation in the eastern Dahomey Basin. They are greenish to grayish, plastic, and in some places contain concretions. In order to assess their sedimentological significance as well as evaluate their potential as industrial raw materials, representative outcrop arid borehole samples .were subjected to mineralogical, chemical and physical characterisation. • • •, •, > l j . Mineralogical determin...
ABSTRACT Mushrooms such as Pleurotus, Vovariella and Auricularia species are cultivated for food and medicinal purposes in the world. However, cultivation of Auricularia in Nigeria is limited due to inadequate information on its characteristics, nutritional contents and cultivation requirements. Hence, this study was designed to characterise Auricularia species in Southwestern Nigeria and determine suitable substrates for their cultivation. Fifty-four samples of Auricularia species were ran...
ABSTRACT Five varieties of white sorghum consumed in Tanzania namely, Pato, Hakika, Tegemeo, Macia and Wahi, non-complemeted and complemented with pigeon peas at ratios 75:25 and 70:30 were extruded to produce instant porridge flour. The physical, nutritional, and sensory quality of the flour was evaluated. The physical quality parameters were: bulk density 0.5-0.7 gcm-3, viscosity 0.5-0.8dpas, water absorption index 0.04-0.6 g/g, water solubility index 24.1-41.2%; the nutritional composition...
ABSTRACT Youth unemployment has become an increasing socio-economic issue in Namibia. Thus, numeral initiatives have been started to fight this trend in order to empower the current marginalised and unemployed youth to sustain a livelihood. This includes skills training opportunities, services and technology development. However, the adoption and integration of such services and technologies has not always been successful. Consequently, this study aims to investigate and implement an appropri...
ABSTRACT Mobile Drug Authentication System was a system that allowed patients to verify drugs or medicines if they are original or fake through a sms. The purpose was to come up with a solution of a system that detects if a particular drug could be original or fake as well generating reports of barcodes that customers sent for verification. This was not possible with the use of a website in making alerts of fake drugs that were being sold to the members of the public as not all people we...
ABSTRACT The NaI(TI) gamma-ray spectrometer was employed to determine the concentration of the naturally occurring Potassium(K-40). Uranium(U-238) and Thorium(Th-232) vis-a-vis the radiogenic heat production in soil samples from Idi-Omo farmland area of Akinyele Local Government area of Oyo state. The farmland which is at Latitude 070 30' 26.3" and Longitude 003" 5 7' 2 1.9" covers an area of about 80,000 square meter, and is at an average elevation of 240m above mean sea level (msl). The s...
ABSTRACT Data has increased at an exponential rate and has outpaced our capability to analyze it. However, new ways of data analysis, which thrive in big data such as Machine Learning (ML) have emerged. This study explores Machine Learning by creating a Machine Learning algorithm based on Support Vectors. This was done by converting mathematical formulations into a computer algorithm that was then used for data classification. The algorithm was evaluated and compared to other algorithms. The ...
ABSTRACT The antimicrobial activities of two Nigerian medicinal plant commonly used as chewing sticks Zanthoxylum xanthoxyloides and Pseudocedrela kotschyi antimicrobial activities were investigated against 7clinical strains of Streptococcus mutans, Staphylococcus aureus ATCC 29213, Candida albicans, Candida tropicalis and Candida krusei ATCC 6825. The antibacterial and antifungal activities of the extracts were determined using the agar well diffusion and surface plate method respective...
ABSTRACT The aim of this study was to assess the levels of pesticide residues in locally produced grape wine in Tanzania. Fifty samples of grape wine from different locations in Dodoma urban and Bahi district were analysed to determine the presence of 49 pesticides using the quick, easy, cheap, effective, rugged and safe (QuEChERS) multi-residue extraction, followed by gas chromatography-tandem mass spectrometry (GC-MS/MS). Twenty-two pesticides were detected among the 49 pesticides analysed....

People are connected to the internet from everywhere. They connect to cyberspace where there is access to the internet i.e. at their home, at their office, ...
ABSTRACT Hepatitis B represents a major global health problem. Despite the high endemicity of hepatitis B in Sub-Saharan Africa, little is known about the epidemiology and genotypes of hepatitis B virus (HBV) in Africa. The few published studies that describe the genetic characteristics of HBV in the Democratic Republic of Congo (DRC) involved a very small adult population size. In the present study, epidemiological and molecular characteristics of HBV infection were studied among voluntary b...
