The cyclic voltammetric measurement and molecular interaction studies using ultrasonic technique of Cu(II),Ni(II) and Pb(II) complexes of  8-[2-Methoxy-5-(propane-1-sulfonyl)-phenylazo]-naphthalene-1-ol using DMSO, were carried out at 303 K. The cyclic voltammetric were carried out at a stationary platinum electrode in DMSO with 0.1M tetrabutylammonium per chlorate (TBAP) as a supporting electrolyte. The measured values of ultrasonic velocity, density, acoustical parameters, adiabatic compressibility and free length are evaluated. From the properties of these parameters the nature and strength of the interactions in these complexes and oxidation, reduction behaviors were discussed.

Textile industry waste water from dyeing and finishing processes constitute a substantial source of water pollution which imparts intense colour, high chemical oxygen demand, fluctuating pH and other suspended particles. This coloured waste water must be treated before final discharge to attain legal standards. Conventional methods for removing dyes from industrial waste water consist mainly of biological and physiochemical treatments and their various combinations. Biological methods are cheaper than other methods but dye toxicity usually inhibits bacterial growth and limits therefore the efficiency of decolourisation. Physical methods usually need additional chemicals which produce secondary pollution and a huge volume of sludge. Water treatment based on electro coagulation technique has been recently proving to evade most of the problems also being economically attractive. This review deals with better understanding of the decolourisation of the textile waste water through Electrocoagulation process. Although there are various electrochemical methods for the treatment of waste water Electrocoagulation has proved to be a clean, versatile, selective, flexible and a powerful process. Decolourisation of the dyeing and finishing waste is greatly affected by the important operating parameters such as the current density, pH, dye concentration, treatment time, type of electrode material used, electrolyte and its concentration. Upon survey it is found that Electrocoagulation combined with other processes also has proved good in the improvement of the decolourisation efficiency.

Recently, modular multilevel inverter(MMLI) have gained interest for photovoltaic applications. This topology minimizes the total harmonic distortion both at the DC and AC side and reduces the voltage stress across the devices for high voltage applications compared to the conventional multilevel inverter. This paper explains the significance of a MMLI by employing phase shift PWM technique. This control algorithm is implemented in SPARTAN/FPGA board. The important aspect of this paper is the issues related to capacitor voltage balancing is addressed. The MMLI is powered by PV source and the modeling of PV alongwith MPPT is implemented in MATLAB. The validity of the proposed modular MLI topology is confirmed by simulation and experimentation.

This paper will deal with the developed wing for the Flying Bike in order to provide the maximum lift in a short takeoff and also to maintain the coefficient of lift for smooth landing, for this the development is carried out with the NACA 4 Digit Airfoil series concept on considering Flat Bottom Airfoil as already in use for sail planes and A-18 Airfoil for Small wind turbines, which have significant results on various models of airfoil but the appropriate one is to be chosen among the symmetrical and flat bottomed airfoil for the best flying concept with minimum drag and maximum speed in air. Also we find airfoil everywhere like in wings, tail surfaces (vertical fin and horizontal stabilizer), Propellers and turbofans, helicopters rotors, compressors and turbines, wind turbines, hydrofoils wing like devices which can lift the water boat above water.

This paper presents a single phase digital prepaid energy meter based on two microcontrollers and a single phase energy meter IC. This digital prepaid energy meter does not have any rotating parts. The energy consumption is calculated using the output pulses of the energy meter chip and the internal counter of microcontroller (ATmega32). A microcontroller (ATtiny13) is used as a smart card and the numbers of units recharged by the consumers are written in it. A relay system has been used which either isolates or establishes the connection between the electrical load and energy meter through the supply mains depending upon the units present in the smart card. Energy consumption (kWh), maximum demand (kW), total unit recharged (kWh) and rest of the units (kWh) are stored in the ATmega32 to ensure the accurate measurement even in the event of an electrical power outage that can be easily read from a 20×4 LCD. As soon as the supply is restored, energy meter restarts with the stored values. A single phase prepaid energy meter prototype has been implemented to provide measurement up to 40A load current and 230V line to neutral voltage. Necessary program for microcontrollers are written in c-language and compiled by Win-AVR libc compiler.

Lead poisoning crisis that crystallized in Bukkyum and Anka local governments of Zamfara State , Nigeria, gave birth to this research works in line with recommendations by Médecins sans Frontières (MSF-Holland) to Zamfara state health authorities.( UNEP/OCHA, 2010). The work consist of Soil sampling and XRF analysis of selected mining stages as well as a host village residential compounds, Dan-company. The concentration levels of Fe, Ni, Cu and Cr are elevated while that of other heavy metals is present within regulatory limits. The elevated levels of metals by their nature do rarely portend hazards to health. The relationship of mining cave values, tailings and residential compounds shows that the villagers of the mining environment might have been educated from the earlier years of the British settlers that flagged off mining in the area.

This paper presents a novel method of allocation of capacitor size for a distribution feeder with uncertain load. The interval mathematics is used to perform the power flow solution of radial distribution system. The simulation results have been obtained using the INTLAB Toolbox in MATLAB environment. The standard 15-bus, 10-bus and the 33-bus radial distribution systems which are used by the researchers have been analyzed to demonstrate the effectiveness of the proposed approach. The developed program gives the range of the capacitor ratings in kVAr which could be selected for compensation, corresponding to the min and max limits of the voltages at each bus. For a range of values of capacitor ratings, which when installed at a particular bus results in the range of reduction in cost of capacitor and energy loss reduction. This information is very useful for a distribution system planner.

Despite that plantain marketing could be used as one of the economic options of breaking the vicious circle of poverty in Nigeria, studies seems not to have existed on the marketing of processed plantain in Umuahia South Local Government Area of Abia State, Nigeria. The study employed a combination of multistage and purposive random sampling techniques to collect data from 120 marketers. In line with the specific objectives, the data generated were analysed using both descriptive and inferential statistics. The results of the analysis revealed that about 67% of the marketers were females who are within the active mean productive age of 32 years. It further showed that plantain are being processed into chips, flour, beverages, plantain ball, pastry, roasted plantain with plantain chips, plantain pastry, and roasted plantain being the most marketed processed plantain in the area. Meanwhile, the identified marketing activities performed by the marketers include advertisement, promotion, packaging, and after sells service in which case, the coefficients of advertisement and promotion (x?) were negatively signed and statistically significant at 5% level; and the coefficients of packaging (X?) and after sells service being positively signed and statistically significant at 1% level. Using the Benefit-Costs-Ratio analysis to determine the return to investment, it was observed that the most economically viable options of marketing plantain is by processing and selling roasted planting, plantain chips, plantain beverages, plantain pastry, plantain flour, and plantain balls. The study recommended for the provision of adequate marketing infrastructures by government and other NGOs to enable marketers make good returns from the marketing of processed plantain within the area.
