The purpose of this study is to measure the concentration levels of radon-222 from seven (7) water samples collected at different sachet drinking-water companies located within Dutsin-Ma LGA using Liquid Scintillation Counter. The levels of radon-222 found to range from (11.69 Bq/L to 13.04 Bq/L), and (9.23 Bq/L to 11.19 Bq/L) with mean values of 12.37 Bq/L and 10.18 Bq/L for borehole and earth-dam sources respectively. The results found are compared with the world average maximum contaminant level (MCL) of 10 Bq/L set by WHO and it was discovered that 86% of the samples are below the value and 100% of the samples are below the WHO recommended reference level of 100 Bq/L. Annual effective doses due to ingestion of radon in water for three (3) categories of people were estimated from the measured radon concentrations and their mean values were found to be (0.090, 0.181 and 0.632) mSv/yr in borehole water and (0.074, 0.149, and 0.520) mSv/yr in surface water (earth-dam) for adults, children and infants respectively. Most of the mean values of the annual effective doses were below the recommended level of 0.1 mSv/yr set by WHO. Therefore, it is recommended that the inhabitants of Dutsin-Ma LGA should always drink the sachet water produce by the companies irrespective of it source.

Solid waste management presents significant challenges in many developing countries in Asia. In this paper we empirically investigate the willingness to participate (WTP) in solid waste management by residents of the Sembulan Tengah Water Village in Sabah, Malaysia by means of a survey study. Sembulan Tengah Water Village is a squatter community populated by poor people subsisting largely in the informal sector. The paper seeks to contribute to the existing empirical literature on the factors that significantly influence WTP generally, as well as WTP in terms of labour hours and pecuniary contributions. Using the binary logistic regression method, our results show that age, gender, educational level, length of stay, house ownership, and ethnicity significantly influence willingness to participate in solid waste cleaning activities. Age significantly influences WTP in terms of labour hours. Other factors, such as gender, education level, length of stay, income level, and house ownership, were significant in influencing WTP in terms of money. Our findings can be used for policy purposes to improve solid waste management in poor communities across developing countries in Asia and elsewhere.

Solar energy is a large inexhaustible source of energy were the power from the sun intercepted by the Earth is over a trillion watt, which is many thousand times larger than the present consumption rate on the earth of all commercial energy sources. The sun could supply all the present and future energy need, presently the major way of extracting this energy is through solar panel and the efficiency of the energy conversion is in high consideration. Research has revealed that different factors can affect the efficiency of the panel, using a DT830B Digital Multi-meter and HTC-1 Clock/Temperature/Hygrometer on a Dp-Li21 polycrystalline solar panel. This work took the liberty of analyzing the effect of humidity and temperature on the efficiency of the solar panel. The result obtained shows that current production is highly aided by temperature within 42-45?C and humidity below 35% and voltage production remains fairly stable with temperature below 42?C and humidity below 60% while the power production is fairly stable with humidity below 40% and maximum with temperature at 45?C, for power production on a panel mounted and to be mounted to be within maximum range, this analysis is to be carried out and put into consideration.

This paper presents a comparative analysis of basic forms of Flexible Alternating Current Transmission Systems (FACTS) Devices. The effect of thyristor firing angle on the transmitted voltage and current by the Thyristor Controlled Reactor (TCR) is presented. The real and the reactive power produced by the Thyristor Controlled Reactor at L = 100mH is also presented. The rate of reactive power absorption and injection on the transmission line by two selected FACTS-Devices such as the Static Var Compensator (SVC) and the Unified Power Flow Controller (UPFC) is mathematically modeled and evaluated with respect to a regulated voltage and current magnitude. Simulation results carried out on the circuit models indicate that Thyristor Controlled Reactor absorbed more reactive power of 1.875KVAR with a reduced overload. The Static Var Compensator injected more reactive power of 28.75KVAR to the transmission line while the Unified Power Flow Controller reduced excess overload through phase angle adjustment with the injection of less reactive power of 675VAR to the transmission line grid. All simulations were actualized in MATLAB 7.14 version.
