Abstract: The experiment was undertaken for one season in Northern Ethiopia, at Emba Alaje District, Ayba Peasant Association to evaluate forage yield of the natural pasture over sown with three adapted legume forages. The design was Randomized Complete Block Design replicated three times. The treatments were control, Vicia dayscarpa, Vicia sativa and alfalfa (Hairy peruvian). The size of experimental plots were 100 m2 (10 m x 10 m) each. Partial Budget Analysis, Dominance Analysis and Marginal Rate of Return were calculated to compare treatments economic benefits. Over sowing legume forages increased Dry Matter Yield significantly as compared with the control pasture land. The higher yield was recorded for pasture land over sown with Vicia sativa (3.96 t/ha) and Vicia dayscarpa (3.12 t/ha). The relative proportion of grass and legumes reached highest and significant by over sowing. However, pasture productivity of land over sown with Vicia sativa and Vicia dayscarpa were not significant for both grass and legumes. The species composition of treatments in the experimental site (Vicia sativa, Vicia dayscarpa and Hairy Peruvian) was 39.3, 33.3 and 7.3%, respectively. It is therefore concluded that over sowing degraded grazing lands with Vicia sativa improves biomass yield, and it is also economical as compared with other treatments. This implies that for every one $ addition cost of biomass yield production there is $ 0.44 (44%) return by applying Vicia sativa.

Abstract: Dielectric parameters vary with frequencies are important properties of biological systems, which determine the absorption rates of electromagnetic radiation in human body. Two phase dielectric model is considered to investigate the dielectric properties of human blood in this paper. This paper systematically calculates the body's specific absorption rate of electromagnetic fields at low frequencies based on the dielectric properties obtained from the Debye model. This study could lay foundation not only for the theoretical basis for further study on electrical properties of biological tissue, but also for the exposure limits of health standard on electromagnetic radiation.

Abstract: This study mainly emphasized on the financial determinants of private sector investment in Ethiopia using annual time series data from 1975-2015. Using Johansen co integration test they have a significant relationship among variables and OLS regression analysis was undertake to estimate long run model and ECM has been used to find out the short run dynamics. In both long run and short run model the financial determinants variable like broad money supply, bank credit and availability of foreign exchange were positive relation with the private investment. The other macro variable taken was the capital expenditure, which is negatively affect in the long run and positively affect private investment in the short run. The researchers conclude based on past literature result’s capital expenditure is positively association with private investment. The short run dynamics of estimated coefficient ECM which suggests a relatively quick speed of adjustment back to the long-run equilibrium. The findings of the study provide evidence that private investment in Ethiopia, like in other developing countries is affected by important financial and macroeconomic variables. The empirical evidence however has certain important policy implications, and in view of that recommendations have also been provided, in an attempt to help increase and stimulate private investment in Ethiopia.
