A spice is a vegetable substance of indigenous or exotic origin, which has a hot pigment taste that could be used to enhance taste of food or add to food some necessary stimulant ingredients. Knowledge of radioactivity levels in human diet is of particular concern for the estimation of possible radiological hazards to human health. In this study, the radioactivity concentrations of 40K, 238U and 232Th in some selected natural food spices commonly used in Nigeria were determined using gamma sp...
In-situ measurement of background ionizing radiation of 10 markets in Port Harcourt metropolis of Rivers State, Nigeria was done using radiation meters and global positioning system. Two portable handheld nuclear radiation monitors (radalert100 and digilert200) to measure exposure dose rate at the various points and a GPS (Germin GPS map 76S for exact positions. The average exposurerates ranged from 0.011 mRh-1 (Mile 1 market) to 0.017 mRh-1 (Rukpokwu international market).The exposure dose r...
It is said that mathematics is the gate and key of the sciences. According to the famous philosopher Kant, “A science is exact only in so far as it employs mathematics”. So all scientific education which does not commence with mathematics is said to be defective at its foundation, In fact it has formed the basis for the evolution of scientific development all over. Taking into cognizance, the usefulness, relevance and importance of mathematics, like bringing positive changes to the scient...
ABSTRACT Sesamun indicum is used for both domestic and commercial purpose in Northern Nigeria, this research is aimed at assessing some micronutrients in sesamum indicum seed in Nguru town, using atomic absorption spectroscopy, spectrophotometric and flame photometric techniques in order to determine the elemental concentrations of some elements in sesame seeds collected from Nguru town, Nguru local government of Yobe state, Nigeria. The results showed the presence of sodium (Na), potassium...
ABSTRACT The research focuses on the impact of non-oil exports on Nigerian economy. It employs the documentary method in retrieving secondary data for the study. The data is retrieved from the CBN statistical bulletin for the year 2016. The method of data analysis is the ordinary least square (OLS) method of multiple regressions using the Microfit software. At the end of the analysis, it is discovered that non-oil exports has a significant impact on the economic growth of Nigeria. I recommen...
ABSTRACT Using basic galvanic cell principles, the ability of tissues to generate electrical current through electrolysis was characterized. Studying Zn/Cu electrolysis in animal organs revealed a fundamental and measurable tissue-specific property – the galvanic apparent internal impedance (GAII), that is most likely related to the salt bridge function of tissues delineated by electrodes. We now report on new fundamental studies on GAII in vegetative matter and on a simple way for signific...
Etrudate characteristics of briquettes produced and effects of extrusion factors using an existing screw extruder have been investigated. The feedstock material used in the test is sawdust collected from sawmills around Ibadan metropolis. Particle distribution analysis of materials collected showed that the size varies between 6-8 mm with 10-20% powdery component (< 4 mesh) which is known to give better products. Samples of briquettes produced were used for physical characterization. Physical...
Groundwater exploration
Abstract A geophysical survey for groundwater resources was carried out in the administrative block of Federal University Dutsin-Ma, permanent site. This was successfully done by employing the electrical resistivity method to investigate the water table variations, the depth to basement, thickness of weathered basement, thickness of aquifer and area suitable for boreholes establishment within the areas covered wit...
Abstract Vertical Electrical Soundings (VES) using Schlumberger array were carried out at different points along five (5) profiles. This research investigates the causes of massive borehole failure at Kaura area of Kaduna state using the resistivity tomography techniques. Terrameter SAS300 is the instruments used to acquire the data. A total of 19 boreholes are functioning, while 31 boreholes are non-functioning within the area. The investigation has portrayed...
Protein is an essential nutritional supplement of food that contain may elements of Amino acid CHAPTER ONE1.1 INTRODUCTION Milk is one of the most nutritious foods. It is rich in high quality protein providing all tenessential amino acids. It contributes to total daily energy intake, as well as essential fatty acids,immunoglobulins, and other micronutrients. Cow’s milk is the predominant type in severalcountries, although goat, buffalo, sheep...
ABSTRACT This study examines the spatial and temporal changes in land use and land cover of Madalla in Suleja Local Government Area (LGA) of Niger State between 1984 and 2013, as well as, the rate of change, factors responsible and suggests measures on how to check the trend in order to maintain sustainable development. The study utilized ILWIS 3.3 software for the processing and classification of the tri-date (19...
Detecting diseases in a child at early stage can enable one to overcome some avoidable diseases that can lead to death of the child and treat them appropriately. This system is poised at a greater extent to reduce infant mortality rate. The Enhanced Child Diagnostic Expert System (DExS) can help the nursing mothers, parents, nannies, guidance and crèche teachers even the medical personnel a great deal in identifying specific diseases and describing methods of treatment to be administered. Th...
ABSTRACT Foods and vegetables belong to an important class of natural products with capacity to exert therapeutic effects – due to presence of phytonutrients. A phytonutrient is any non – toxic food component that has scientifically proven health benefits, including diseases prevention and treatment. This article focuses on about 40 Natural products (fruits, vegetables, spices) which includes Water melon (Citrulus lanatus), Apple (Malus domestica), Pawpaw (Asimina triloba) and Banana (Mu...
