This paper describes a modification of the Free-Space and Hata formulae for the prediction of received signal power, PR and propagation path loss, LP, in two Cellular Mobile Radio Systems (CMRS), in the Northern Nigeria. Measurements of PRs were taken with a Cellular Mobile Radio test receiver (Sagem OT 160), in some selected open/rural environment

This book addresses the concept of inter-religious dialogue promoted by Nostra Aeate (The Declaration on the Relation of the Church to non-Christian Religions, promulgated on October 28, 1965), and the Holy Qur’an, as the only means to change the attitude of Muslims and Christians from that of hostility to mutual respect and better, objective and

This study was conducted to determine the potential of fruit waste materials as sources of natural antioxidant. Seeds are major byproducts during the processing of fruits-based products such as puree, canned slices, juice and pickles. Normally, the seeds will be discarded as waste since they are not currently utilized for any commercial purposes. T

Wireless mesh networks (WMNs) have emerged as a key technology for next-generation wireless networking. Because of their advantages over other wireless networks, WMNs are undergoing rapid progress and many exciting applications. Although WMNs can be built up based on existing technologies, field trials and experiments with existing WMNs prove that

The phenolic compositions of non-germinated/germinated seeds and seed sprouts (at 6–10 day-old) of common (Fagopyrum esculentum Möench) and tartary (Fagopyrum tataricum Gaertn.) buckwheats were investigated. Phenolic compounds, including chlorogenic acid, four C-glycosylflavones (orientin, isoorientin vitexin, isovitexin), rutin and quercetin, w

Purpose. To evaluate the effect of autologous human serum (AHS) versus pooled human serum (PHS) versus foetal bovine serum (FBS) for growth of articular chondrocytes and formation of chondrocytefibrin constructs. Methods. Experiments with monolayer culture expansion of human articular chondrocytes were performed using basic culture media supplement

Attenuation (scattering and absorption) of gamma photons in the patient’s body is one of the major limitations among the others in single photon emission computed tomography (SPECT). It reduces quantitative accuracy of measured radioactivity concentration and causes hot rim artifacts in reconstructed images if not corrected for. A variety of appr

An established method to detect a target from the FMCW radar signal is implemented by using the method of range FFT (Fast Fourier Transform). By repeating the same procedure many times at a certain azimuth angle, it is possible to additionally compute the radial speed of the suspected target. This paper describes a method to determine the radial sp

A well-known method to detect a target from FMCW radar signal is implemented using range FFT. By repeating the same procedure many times at a certain azimuth angle, one can additionally determine the radial speed of the suspected target. This work describes a simple method in determining the radial speed of target by extracting a series of phase da

The present study was carried out to monitor the plankton community structure and productivity, its diurnal and seasonal variations and the influence of physico-chemical factors in the Shibsha River of the southwest coast of Bangladesh from July 2004 to June 2005. A total of 31 phytoplankton species were identified; 17 belong to Bacillariophyceae,
