Ibrahim Elnour Ibrahim
The purpose of this study was to measure and analyse the economic efficiency, and to identify the main factor behind economic efficiency of sorghum and millet for small scale farmers in traditional rainfed sector in North Kordofan State. Primary data is collected using structured questionnaire for a sample of 205 farmers from four localities namely (Sheikan, Umrwaba, Elnuhoud, and Elkhowi). Stochastic frontier approach (cost function) was used to analyse economic efficiency and descriptive statistics were used to analyse socio-economic characteristics of farmers. The results of stochastic frontier cost function revealed that the estimated economic efficiency of the sorghum and millet farmers obtained was found the mean economic efficiency to be 39% and 15%, respectively.

2018
Shemelis Kebede Hundie
Policy makers need to know the relationship among energy use, economic growth and environmental quality in order to formulate rigorous policy for economic growth and environmental sustainability. This study analyzes the nexus among energy consumption, affluence, financial development, trade openness, urbanization, population and CO2 emissions in Ethiopia using data from 1970–2014. The ARDL cointegration results show that cointegration exists among the variables. Energy consumption, population, trade openness and economic growth have positive impact on CO2 in the long-run while economic growth squared reduces CO2 emissions which confirms that the EKC hypothesis holds in Ethiopia. In the short-run urbanization and energy consumption intensify environmental degradation. Toda-Yamamoto granger causality results indicate the bi-directional causality between energy consumption and CO2 emissions, CO2 emissions and urbanization. Financial development, population and urbanization cause economic growth while economic growth causes CO2 emissions. Causality runs from energy consumption to financial development, urbanization and population which in turn cause economic growth. From the result, CO2 emissions extenuation policy in Ethiopia should focus on environmentally friendly growth, enhancing consumption of cleaner energy, incorporating the impact of population, urbanization, trade and financial development.

The antibacterial and antioxidant activities of Lavandula stoechas and Crepis sancta extracts on subclinical mastitis bacteria in cows have not been reported to the present day. The aim of this work was to investigate of the antibacterial and antioxidant potential of methanol extract from L. stoechas and C. sancta. Methanol extracts were screened for antibacterial activity against mastitis pathogens. The antibacterial activity was tested using disc diffusion and broth dilution method. In addition, the plant extracts were tested against the stable DPPH (1,1-Diphenyl-2-picrylhydrazyl) free-radical. Additionally methanol extracts were screened for enzymatic antioxidant activity. The methanol extract of C. sancta showed maximum inhibition zone against S. aureus-18 (16 mm). MIC (minimum inhibition concentration) value was determined as 3250 µg/mL for test bacteria. The highest radical scavenging capacity (62 %) was obtained from the flower extracts of L. stoechas and the leaf extracts of C. sancta. The methanol extract of C. sancta displayed a strong antioxidant activity (trolox equivalent = 1.6 mM/g). It was determined that the activities of catalase (CAT) and ascorbate peroxidase (AP) enzymes were higher at the flowers of L. stoechas compared to the leaves. The extracts of L. stoechas and C. sancta leaf and flower have antibacterial and antioxidant potential against subclinic mastitis causative agent Staphylococci species.
