Effect of soil moisture conservation and planting methods on soil moisture content and yield of sorghum (Sorghum bicolor (L.) Moench) under rain-fed conditions of Tigray, Ethiopia

Crop production in semi-arid dry land areas of Ethiopia is totally dependent on erratic rainfall-uneven distribution, torrential in intensity, low in amount during crop growing season, and variable from year to year. This results in unpredictable agricultural production and occasional crop failure. Therefore, the study was designed to evaluate the effect of in-situ moisture conservation techniques such as tied ridge and...

Study of the performance parameters of a silicon solar cell (n+/p/p+) in frequency modulation placed in a medium dominated by the magnetic field: Effect of low and high doping rate

This work focuses on the study of the effects of low and high doping rate of a silicon (n+/p/p+) solar cell in frequency modulation placed under magnetic field with Matlab Simulink software. The importance of this work is to highlight the effects of the doping rate and the magnetic field on the current-voltage characteristic, the open circuit voltage (Vco), the short circuit current and the efficiency. The doping rate...
