Abstract Tungsten will be used as the plasma-facing divertor material in International Thermonuclear Experimental Reactor (ITER) fusion reactor. Under high temperatures and ion fluxes, a ‘fuzz’ nanostructure forms on tungsten surface with dramatically different properties could contaminate plasma. Although simulations experimental observations have provided understanding of initial fuzz formati...
Drought stress is the most important limiting factor in crop plants including maize (Zea mays L.), which is the third important world crop after wheat and rice. Water deficiency at different growth stages affects maize yield differently. To examine the response of four maize hybrids to drought stress at different growth stages, a field experiment was carried out as a split plot based on complet...
Partial stage and complete life-cycle growth curves of Brahman cattle were obtained for small, medium, and large frame sizes for a herd under grazing conditions in a subtropical environment. Data were grouped into three stages: birth to weaning (stage 1), weaning to 20 mo (males) or 32 mo (females) of age (stage 2), and 32 mo of age to maturity (females only; stage 3). Within each stage, multip...
