The effects of exposure to low temperature on photosynthesis and protein phosphorylation in chilling-sensitive and cold-tolerant plant species were compared. Chilling temperatures resulted in light-dependent loss of photosynthetic electron transport in chilling-sensitive rice (Oryza sativa L.) but not in cold-tolerant barley (Hordeum vulgare L.). Brief exposure to chilling temperatures (0-15 de...
Over millions of years Nature has attained highly optimized structural designs with remarkable toughness, strength, damage resistance and tolerance - properties that are so far difficult to combine in artificial high-performance fibre-reinforced polymers (HPFRPs). Recent studies, which have successfully replicated the structures especially toughening mechanisms found flora fauna, reviewed this ...
In nature plants are often simultaneously challenged by different biotic and abiotic stresses. Although the mechanisms underlying plant responses against single stress have been studied considerably, plant tolerance mechanisms under combined stress is not understood. Also, the mechanism used to combat independently and sequentially occurring many number of biotic and abiotic stresses has also n...
With the strong battlefield application environment of next generation fighter, based on design distributed vehicle management system, a fault diagnosis and fault-tolerant control (FTC) method for wing surface damage is proposed in this paper. Aiming at three kinds modes, paper proposes decision tree forms from aspects sample database construction, feature parameter extraction, construction. Ba...
a comprehensive review of fatigue behavior and fatigue design of heavy section wind turbine castings made of ductile iron en-gjs-400-18-lt is performed. common metallurgical defects that are affecting fatigue behavior of this material were studied. review of different researches on quantitative effect of chunky graphite and micro structure on fatigue behavior of en-gjs-400-18-lt was performed. ...
When subjected to shade, plants undergo rapid shoot elongation, which often makes them more prone to disease and mechanical damage. Shade-tolerant plants can be difficult to breed; however, they offer a substantial benefit over other varieties in low-light areas. Although perennial ryegrass (Lolium perenne L.) is a popular species of turf grasses because of their good appearance and fast establ...
Winter cold is a significant damaging factor in fruit trees specially stone fruits. Relative resistance of 20 local and introduced sweet cherries (Prunus avium) to winter cold in artificial cold condition and its association with electrical conductivity and a number of morphological traits including trunk diameter, shoot diameter, anthocyanine and lenticels frequencies was studied in year 2011....
