The main objective of this study was to determine the concentrations of toxic heavy metals (lead, cadmium and copper) in some fruits (guava and tomato) and vegetables (onion, okra, sorrel, garden egg, potato, cucumber, carrot and spinach) commonly grown and consumed in Borno State. The fruits and vegetables were purchased directly from Monday Market Ltd in Maiduguri at their peak seasons. Each sample was subjected to two treatments (washed and unwashed), dry-ashed at 500 - 5500C for 12 – 18 hours to extract the heavy metals (analyte) and each analyte was subsequently quantified using Atomic Absorption Spectrophotometer (AAS). The results indicate that the concentration of copper was negligible in all the crops; the highest concentrations of the metals were observed in spinach, these were 0.2250 ppm and 0.0325 ppm of lead and cadmium, respectively. The concentration of lead was higher (P<0.05) in the unwashed sample (0.1121 – 0.5010ppm) compared with 0.0132 – 0.2250ppm for the washed samples; that of cadmium were 0.0023 – 0721ppm and 0.0010 – 0.0325 ppm in the unwashed and washed samples, respectively. Significant difference (P<0.05) was observed in the concentration of the metals between and within crop samples indicating the effects of crop types on metal concentration. The leafy vegetables had higher (P<0.05) concentrations of the metals than the fruits. The fact that considerable amounts of the metals were removed by washing suggests that the contamination was a surface type.

this paper gives the brief out line about the worldwide production cottonseed & its oil, Cotton Seed Oil (CSO) properties, its comparison with diesel and Jatropha biodiesel. It investigates the performance of a diesel engine using diesel fuel and cottonseed oil (CSO) biodiesel in terms of brake thermal efficiency and indicated thermal efficiency for conventional diesel, cottonseed oil, as well as for Jatropha oil. For this aim, A Single Cylinder, 4-stroke vertical, water-cooled, self-governed diesel engine developing 5 HP at 1500 rpm (Rope brake dynamometer with spring balances and loading screw. Brake drum diameter = 0.400 m.) engine is selected for the testing with diesel fuel and neat bio-diesel, which is cottonseed oil methyl ester, at full load conditions. The evaluation of theoretical data showed that the brake thermal efficiency and indicated thermal efficiency of CSO biodiesel was slightly higher than that of diesel fuel and Jatropha oil. This study reveals that the use of cottonseed oil biodiesel improves the performance parameters of CI engine compared to conventional diesel fuel.

The laser is an acronym for Light Amplification by Stimulated Emission of Radiation. This is an unique beam of light which has properties of spatial coherence and temporal coherence simultaneously. The fundamental source of noise in a laser is spontaneous emission. This is also related to the so called laser linewidth which is attributed to the random phase diffusion process arising from the addition of spontaneously emitted photons with random phases to the laser field .In the present work we show that the quantum noise leading to the laser linewidth can be suppressed below the standard limit (Schalow-Townes limit) by preparing the atomic systems in a coherent superposition of states as in the Hanle -Effect and Quantum Beat experiments. In such coherently prepared atoms the spontaneously emission is said to be correlated. Lasers operating via such a phase coherent atomic ensemble are known as correlated spontaneous lasers (CEL). An interesting aspect of Correlated Emission Laser is that it is possible to eliminate the spontaneous quantum noise in the relative linewidths by correlating the two spontaneous emission noise events. A well defines coherence between the upper and lower levels leads to a correlation between the light emitted by an transition in a three level system. In this work we present a coupled pendulum analogy which illustrates CEL.

Nanocrystalline powder of 0.1 mol% Eu doped BaSO4 were synthesized by chemical co-precipitation technique. The formation of the powder was confirmed by the Powder X-ray Diffraction (PXRD) analysis. Shape and size of the synthesized powder were examined using Transmission Electron Microscope (TEM). Dosimetric characteristics have been carried out of the γ-ray irradiated BaSO4:Eu phosphors using Thermoluminescence (TL) technique. The TL glow curve of the samples shows the dosimetric peak at around 456 K which is sufficient above the room temperature. Composite TL glow curve of the synthesized powder deconvoluted using general order kinetics equation and also calculated the kinetic parameters.

This paper describes the steady-state response and control of power in transmission line equipped with FACTS devices. Detailed simulations are carried out on two-machine systems to illustrate the control features of these devices and their influence to increase power transfer capability and improve system reliability. The DPFC is derived from the unified power-flow controller (UPFC) and DPFC has the same control capability as the UPFC. The DPFC can be considered as a UPFC with an eliminated common dc link. The active power exchange between the shunt and series converters, which is through the common dc link in the UPFC, is now through the transmission lines at the third-harmonic frequency. The interaction between the DPFC, the network and the machines are analyzed.

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes dynamically forming a network topology without the use of any existing network infrastructure or centralized administration. One of the main procedures for evaluating the performance of MANETs is simulation. In this paper, the comparison is made for the performance of routing protocols i.e. Ad hoc On Demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Destination Sequence Distance Vector (DSDV) over a MAC Layer protocol IEEE 802.11. As per our findings the differences in the protocol mechanics lead to significant performance differentials for these protocols. Always the network protocols were simulated as a function of mobility, but not as a function of network density. In our paper the performance of AODV, DSDV and DSR is evaluated with respect to performance metrics like Packet Delivery Fraction (PDF), Average end-to-end delay, Normalized Routing Load (NRL), and Dropped packets by varying network size. These simulations are carried out using the NS-2 which is the main network simulator.

The present study is concerned with the effect of welding current, voltage, welding speed and external magnetic field on tensile strength of shielded metal arc welded mild steel joints. Mild steel plates of 6 mm thickness were used as the base material for preparing single pass butt welded joints. Speed of weld was provided by cross slide of a lathe, external magnetic field was obtained by bar magnets. Tensile strength of the joint fabricated by E-6013 electrodes as filler metals was evaluated and the results were reported. From this investigation, it was found that the joints fabricated have increased tensile strength if either speed of weld or external magnetic field was increased and this mechanical property decreased if either voltage or current was increased. An artificial neural network technique was used to predict the tensile strength of weld for the given welding parameters after training the network.

A lot of new houses in the housing area, it built and sold to the public in the city of Bandung. Bandung is the capital of West Java province, the third-largest city in Indonesia after Jakarta and Surabaya based on its population. In the year 2007, British Council makes the town Bandung as a pilot project for the town of most creative in East Asia. Until the year 2012, many of the houses built by developers in the Bandung city. Some housing continues to expand the area of housing, one of them is housing SP. Survey conducted at housing SP owning wide of building 200 sqm. House building enthused by well established productive family. Its problem emerged when happened by a lot of change in dwelling space, only 32%, which can be accepted by a consumer. This research used the method qualitative, comparing between functional space criterion theory with the fact that happened at a study object. The findings are useful for the development of architectural design provided by the developer to the community and the environment.

Key Words: housing, economy, optimal.
