The control of a drinking-water treatment plant aims to produce the correct quantity of water, with a constant quality. Achieving constant water quality is not an obvious task, since the online water-quality measurements and possible control actions are limited. Applying model-based control improves disturbance rejection and online process optimisation. For the softening process step, the integ...

green olive cultivars “manzanila” and “mission” were harvested at the mature green stage. they were either treated with 1-methylcyclopropane (1-mcp) at a concentration of 1.8 µl/l for 24 h at 20°c or kept untreated as a control. both treated and untreated fruits were then immersed in water containing cacl2 of 0 (control), 50 and 100 mm for 2 h under 1.2 bar pressure. fruits were then surface dr...

fruit browning and tissue softening due to damages during handling, quality losses and water loss are the major limiting factors reducing postharvest life of early ripening apples. in this study, the effect of salicylic acid (sa) on fruit quality of apple cv ‘golabe-kohanz’ during postharvest life were investigated. harvested fruits were immersed in zero, one, two and four mm sa and were mainta...

The mechanism by which seal-packaging individual fruit in high density polyethylene film delays deterioration was investigated with lemon (Citrus limon [L.] Burm. f. cv Eureka) and bell pepper (Capsicum annuum L. cv Maor) fruits. Seal-packaging effects were due to the water-saturated atmosphere in the sealed enclosure around the fruit. Softening of fruit was highly correlated with declining wat...

experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304h stainless steel. three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the drx critical strain: strongly strain dependent softening by srx alone with softening kinetics control...
