The intensity of damage in concrete structures has a vital relationship to the position of concrete respect to sea level. A hydraulic model consists of a channel and a wave maker machine capable of making regular waves with various heights and periods, has been designed and constructed in hydraulic laboratory to simulate the marine environment and conditions in this research study. The Oroomiye...
Eight spring wheat cultivars were evaluated under three heat stress conditions (early, late and very late) in order to identify suitable cultivars to develop heattolerant genotypes resistant to future global warming. Results from the study indicate that stress did not negatively affect flag leaf area in ‘Prodip’ and ‘Sufi’, flag leaf dry matter partitioning in ‘Prodip’, ‘BARI Gom-26’ and ‘S...
