An Efficient RLT based Multinode Wireless Energy Charging in Sensor Networks
Abstract: The new generations of networks are sensor networks which typically consist of a large number of nodes that are connected wirelessly. The main idea of these types of networks is collecting data around the network's sensors. Since the sensors nodes work with the battery and there is no possibility to change or recharge these batteries, the life time of these networks depends on the sensors energy. However, multihop networks suffer …

Fiber Optic Fluorescent Probe for Measurement of Temperature
Abstract: A fiber optic temperature monitoring probe has been developed. Its sensing element uses the temperature sensitive fluorescence of Cu-activated calcium sulphide (CaS) phosphors. These phosphors have been synthesized by solid state fusion reaction. The excitation and emission spectra of the phosphor coatings have been recorded at room temperature (25ºC). The temperature dependence of fluorescence intensity and the lifetime of phosphorescence have also been studied. From the systematic variation of these …

Radio-Assay of Plant Samples at the Proposed Nuclear Reactor Site in Geregu, North-Central Nigeria
Abstract: Radio-assay of plant samples at the Geregu site, North-Central Nigeria, was evaluated to determine the radiological burden on the environment. Plant samples were collected from ten different locations on the site and the concentrations were measured using gamma spectroscopy. Radiological equivalent dose was estimated using standard analytical methods. The mean value for the external outdoor absorbed gamma dose rates due to terrestrial γ-rays from the nuclides Ra-226, Th-232 and K-40 …

Energy Efficient for Heat Exchanger, Refrigeration and Air Conditioning
Abstract: Scientifically, it is difficult to predict the relationship between global temperature and greenhouse gas (GHG) concentrations. The climate system contains many processes that will change if warming occurs. Critical processes include heat transfer by winds and tides, the hydrological cycle involving evaporation, precipitation, runoff and groundwater and the formation of clouds, snow, and ice, all of which display enormous natural variability. The equipment and infrastructure for energy supply and use …

Assessment of Human Health Risk Factors Associated with Using Portable Water from the River Benue at Makurdi
Abstract: The non-carcinogenic and carcinogenic risk posed to children and adults by Cadmium, Nickel, Zinc and Lead concentration in River Benue water were evaluated in this study. Sampling for the metals was conducted on three locations in transect of north bank, middle stream and south bank making a total of nine stations. These metals were estimated as hazard index (HI) which took into account the combined effects from the heavy metals …

The “Less Paper” Library and Its Effects on Environment, Economy and Efficiency
Abstract: AbstractDuring the last 40 years, people began talking about the option of a “paperless library”. The concept of electronic format has been emerging out, i.e., everything is available on the internet; everything is now in electronic form so there is no need of paper. It coincided with the advent of the personal computer, and the hope was that all documents could be processed electronically and that paper would become inappropriate. …

Health Benefits of Natural Products to Overcome Digestive Problems
Abstract: Digestive health is an indicator of proper laxation and proper functioning of the gastro-intestinal system. Digestion-related problems not only lead to/give discomfort, but also pave way for more serious manifestations, which may either last for some time or prolong till lifetime or in some cases end fatal. The drugs which help in relieving certain digestive problems, mainly flatulence, are carminative and most of the spices and evaluating the effectiveness of …
