Radiation Monitoring Along The Creeks Of Calabar River And Its Environs

Measurement of gamma-ray exposure rate using a portable dosimeter was taken. The exposure rate was taken one meter above water and ground levels for radiological assessment at the Calabar River and its environs of Cross River State, Nigeria. The study reveals equivalent dose rate of 0.007µSv/hr and 0.115µSv/hr within the river and its environs respectively. Subsequently, the values are considered far below the radiation limits of 1mSv stipulated for members of public per year.

Application of total reflection x-ray fluorescence (TXRF) technique for elemental analysis of Nigerian crude oils

Nigerian crude oils from eight oil wells have been analysed for the following trace elements: Ni, Cr, Mn, V, Fe, Zn. Pb, Cu, Co and S using total Reflection X-ray Fluorescence (TXRF) analytical method. Concentrations of these elements were found to range from 0.002 – 1.420 ppm. Results showed that Fe was the most abundant metal with Inim oil well containing the highest concentration of the Fe. The V/Ni ratio for the method showed that Mfem 8B and Ubit 106C were the most and the least matured oil wells respectively from this study. Keywords: crude oils, trace elements, concentrations, TXRF, maturityNigerian Journal of Physics Vol. 17, 2005: 103-10

Trajectory Coherent State And Coherent State For The Modified Caldirola-Kanai Oscillator

We construct the Trajectory Coherent State (TCS) and Coherent state (CS) in the framework of the Modified Caldirola Kanai Hamiltonian. We also evaluate the minimum uncertainty relation.Keywords: Coherent state,modified caldirola-Kanai oscillator,uncertainty relation
