the scarcity of irrigation water and decrease of water resources are the most important limiting factors in crop production in countries such as iran. thus, studying the optimum use of water and increasing water use efficiency are essential to the agricultural sector. the use of a low pressure hydroflume has been suggested to replace traditional surface irrigation methods. the aim of this resea...
Nowadays, hydrogels are widely used as wound dressings in biomedical applications. Similar to other types of the moist (wet) wound dressings, it is necessary to have sufficient information about their dehydration kinetics during the pre-usage period (e.g. storage duration) and also the wound healing process. In this work, hydrogel wound dressings based on polyvinyl alcohol were prepared by...
The idea that Na(+) retention inevitably leads to water retention is compelling; however, were Na(+) accumulation in part osmotically inactive, regulatory alternatives would be available. We speculated that in DOCA-salt rats Na(+) accumulation is excessive relative to water. Forty female Sprague-Dawley rats were divided into four subgroups. Groups 1 and 2 (controls) received tap water or 1% sal...
The objective of this work was to formulate a mathematical model for predicting a safe weight of lift. Considering the intratruncal pressure, post-work height shrinkage of the worker and strain energy of the intervertebral disc, the SWL function was derived in terms of the Young Modulus of elasticity (E) of the articular cartilage (endplate of the disc); velocity of lift (u); acceleration due t...
OBJECTIVES The high mortality rate observed on the regular waiting list (RWL) before lung transplantation (LTx) prompted the French organ transplantation authorities to set up in 2007 a dedicated graft allocation strategy, the so-called 'high-emergency waiting list' (HEWL), for patients with an abrupt worsening of their respiratory function. This study reports on the early results of this new a...
We introduce a relative variant of information loss to characterize the behavior of deterministic input-output systems. We show that the relative loss is closely related to Rényi’s information dimension. We provide an upper bound for continuous input random variables and an exact result for a class of functions (comprising quantizers) with infinite absolute information loss. A connection betwee...
In the literature a number of relative loss bounds have been shown for on-line learning algorithms. Here the relative loss is the total loss of the on-line algorithm in all trials minus the total loss of the best comparator that is chosen off-line. However, for many applications instantaneous loss bounds are more interesting where the learner first sees a batch of examples and then uses these e...
