Southern Ethiopia Rift Valley lake fluctuations and climate

This study describes hydrological fluctuations of Lake Abaya-Chamo via direct local measurements in relation to time-integrated climate anomalies. Reconstruction of an index involved compositing lake level and flow discharge station records in the period 1983-2009. Satellite and model interpolated rainfall, latent heat flux and run-off anomalies follow the hydrological records when summed over and lagged by one year....

Effects of elevated temperature on seed germination and seedling growth on three cereal crops in Nigeria

The effect of elevated temperature on seed germination and seedling growth was investigated on three Nigerian cereal crops: maize, rice and sorghum. Seeds where then allowed to germinate in controlled growth at 37 (control: room temperature), 40, 42, 45 and 50°C and monitored for germination, shoot length and root length for 24, 48, 72 and 96 h, respectively. Seeds were also sown in small poly bags in triplicates...

Enhancing container transportation traceability based on intelligent product and web-services: Model driven approach

Containers transportation involves various intermediate supply-chain actors. These containers are subject to myriad risks that can occur at any moment. In addition, the absence of a specialized stakeholder for securing containers flow and the lack of communication among actors impedes identifying responsibilities when an adverse event arises. For this purpose, we advocate the use of traceability system to enhance...

Antioxidant and antibacterial activities of saponin fractions of Erythropheleum suaveolens (Guill. and Perri.) stem bark extract

Erythropheleum suaveolens stem bark saponins fractions were investigated for antioxidant and antibacterial activities. In vitro systems such as, 1, 1- diphenyl-2-picrylhydrazyl (DPPH) radical, reductive potential and inhibition of lipid peroxidation were carried out to determine the antioxidant activities. The antimicrobial activity was determined using the hole-in-plate agar diffusion technique and the minimum...
