An experimental investigation of applying a magnetic field and a radiation source horizontally with the direction of alloy once and vertically in another, current range passing through alloy is (1-3) AMP. The increase in temperature will lead to reduce electrical conductivity. The increase in input power causes an increase in output power. The increasing in magnetic field intensity will increase alloy efficiency. The increase in radiation time will increase alloy efficiency. The increase in magnetic field intensity in the presence of radiation will increase the alloy efficiency.

An experimental investigation of applying a magnetic field and a radiation source horizontally with the direction of alloy once and vertically in another, current range passing through alloy is (1-3) AMP. When a magnetic field applied vertically with the direction of alloy, the resistance is higher than in case of applying it horizontally. The increase in radiation time will increase the alloy resistance. The increase of resistance will increase temperature in case of applying the magnetic field in vertical direction. The increase in resistance, the temperature approximately satiable.

Locally produced fruits (mango, pineapple and banana) were sampled and purchased from farms and markets within the Yilo and Lower Manya Krobo districts and analyzed for pesticide residues by gas chromatography equipped with an Electron Capture Detector (GC-ECD). In all, 80 samples made up of 40 mango samples and 20 samples each of pineapples and bananas were extracted and analyzed for mainly organochlorine residues (?-HCH, ?-HCH, aldrin, dieldrin, heptachlor, ?-chlordane, endosulfan s, p, p’-DDE etc.) and synthetic pyrethroid residues (allethrin, bifenthrin, fenpropathrin, permethrin, cyfluthrin etc.). Analysis indicates that about 88% of the mangoes sampled from the farms contained one or more of these pesticide residues. 75% and 65% of the pineapples and bananas respectively from farms and markets had one or more of the analyzed pesticide residues. The data revealed that about 6.2% of the fruit samples analyzed contained organochlorine pesticide residues of ?-HCH (0.013mg/kg and 0.038mg/kg respectively in mangoes and pineapples); ?-HCH [0.014mg/kg (mango) and 0.024mg/kg (pineapple)]; methoxychlor [0.027mg/kg (mango) and 0.048mg/kg (pineapple)]. Synthetic pyrethroid residues of cyfluthrin [0.078mg/kg (mango) and 0.059mg/kg (pineapple)] and fenvalerate [0.025mg/kg and 0.028mg/kg respectively for mango and pineapple] were also found above their respective maximum residue limits whereas 78.2% of detected pesticide residues were below the MRLs. Nonetheless, the continuous consumption of these fruits with even the modest pesticide levels can result in accumulation that could result in deadly chronic effects. In assessing the consumers’ perception of pesticide residues in fruits, about 69% of the respondents were aware of pesticide residues in fruits and the corresponding adverse effect on human health. Some have experienced pesticide poisoning after fruit consumption. Thus many wish pesticide usage in fruit and crop cultivation in general is curbed or minimized to only those who can ensure reduced levels.

Spherical shaped CuO nanocrystals were successfully synthesized by sol–gel technique. Triethanolamine (TEA) used as a capping agent to control the size, morphology and optical properties of the CuO nanocrystals. Evolution of structure, surface morphology and optical absorption analysis of these nanocrystals were studied using UV–Visible spectrophotometer (UV–Vis), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Field Emission Scanning Electron Microscopy (FE-SEM) and energy dispersive X-ray spectroscopy (EDS). UV–Visible technique used to measure the band gap of TEA capped CuO nanocrystals having good optical property compared than uncapped CuO nanocrystals in the synthesized samples. The FT-IR study of transmittance peaks at 502 cm-1,603 cm-1 and 674 cm-1 were Cu-O stretching mode, and 677 cm-1 has been Cu-O monoclinic phase of the uncapped CuO nanocrystals. In addition the transmittance peaks at 502 cm-1, 583 cm-1 have been Cu-O Stretching mode and 784 cm-1 are Cu-O monoclinic phase of the Triethanolamine capped CuO nanocrystals.
