The optimum design of solar energy systems strongly depends on the accuracy of  solar radiation data. However, the availability of accurate solar radiation data is undermined by the high cost of measuring equipment or non-functional ones. This study developed a feed-forward backpropagation artificial neural network model for prediction of global solar radiation in Makurdi, Nigeria (7.7322  N lo...

Background: Activity concentrations of 40K, 226Ra and 228Ra were measured in some sachet drinking water samples produced in Nigeria. Materials and Methods: The measurement was done by using high-purity germanium (HPGe) detector (Canberra Industries Inc.). The measured activity concentrations for 226Ra (U-series) and 228Ra (Thseries) were used with their ingested dose conversion factors ...

Lion fecal DNA extracts from four individuals each from Yankari Game Reserve and Kainji-Lake National Park (central northeast and west Nigeria, respectively) were Sanger-sequenced for the mitochondrial cytochrome b gene. The sequences were aligned against 61 lion reference sequences from other parts of Africa and India. The sequence data were analyzed further for the construction of phylogeneti...

BACKGROUND There is paucity of data on the nutritional status of school-age children in Sagamu town of Southwestern Nigeria. OBJECTIVE To determine the nutritional status of primary school children in Sagamu Local Government Area, Nigeria. METHODS A cross-sectional survey of primary school children aged 6 to 10 years in Sagamu, Southwestern Nigeria was done. Eight schools were selected usin...

BACKGROUND Plasmodium falciparum, the most dangerous malaria parasite species to humans remains an important public health concern in Okelele, a rural community in Ilorin, Kwara State, Nigeria. There is however little information about the genetic diversity of Plasmodium falciparum in Nigeria. OBJECTIVE To determine the population genomic diversity of Plasmodium falciparum in malaria patients...

Maize is a major complimentary food for infants (0-4years) and young children (5-12years) in Nigeria. In this study, we assessed the risk of exposure of infants and young children (IYC) to some major mycotoxins in stored maize grains from five agro-ecological zones of Nigeria. The probable daily intake approach was employed to determine exposure to five mycotoxins while the margin of exposure (...

The consequences of Maternal Mortality (MM) cannot be overemphasized. It inhibits population growth resulting into loss of lives among others. This work tends to obtain the maternal mortality rates (MMR) in Nigeria, identify some fitted distributions to MMR and determine which of the distributions best fits the data. A comprehensive Exploratory Data Analysis (EDA) was carried on MM and the MMRs...

background:there is no comprehension data on anatomicalindices of nigerian goats. objectives: to show osteometricvalues of some cranial indices in nigerian goats. methods:sixty (60) goat skulls that were found around makurdi, kwande,katsina-ala and the neighbouring adamawa state of nigeria,were studied by investigating the 30 craniometric values.results: the measured distance from the facial tu...

The paper determined optimum farm plan for food security among smallholder farmers in Imo State, Nigeria. Data were collected with structured and validated questionnaire from 180 smallholder crops farmers in Imo State. Data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. Results show that the mean age of...
