the study was designed to investigate the comparative analysis of agricultural credit users and non-users among cassava farmers in ohafia local government area of abia state. a sample of 50 credit users and 50 non-credit user cassava-based farmers were selected by multistage random sampling technique. data were collected with a well structured questionnaire administered to a total of 100 random...

All algorithms for impedance calculation use an analog-to-digital converter. The high accuracy of the impedance seen by a distance relay is an important factor in the correct isolation of the faulty part of power systems. To achieve this, a novel&#10technique based on third order interpolation is used in this paper. According to this technique, the times and the values of the obtained samples a...

one of the most valuable and important application of artificial satellites in geodetic sciences is recovery of the earth's gravity field. orbits of satellites either gravimetric or nongravimetric are analyzed to improve the earth's gravity field. gravimetric satellites are launched at low altitudes to observe gravity field in more detail. grace twin satellites are the second spacecra...

results the results revealed that metal urine concentration in welders was higher than controls but only the difference in chromium concentration was significant (p < 0.002). in the range of metals exposure, induction of oxidative stress for exposed group was observed by increase in urine mda (11.17 ± 4.23 and 4.83 ± 1.82 mm in welders and controls, respectively; p < 0.01). information of the m...

This work deals with the weighted excesses of players in cooperative games which are obtained by summing up all coalitions to they belong. We first show that resulting payoff vector is corresponding least square value lexicographically minimizing individual over preimputation set, and thus give an alternative characterization values. Second, we these results rise lower upper bounds for core vec...

Abstract Vector Autoregressive (VAR) is a multivariate time series model for examining objects with two or more variables in which the affect each other under stationarity assumption. This study aims to compare parameter estimation procedure of VAR(1) Ordinary Least Square (OLS) and Maximum Likelihood Estimation (MLE) methods. The comparison investigated by both theoretical empirical approaches...
