PURPOSE This study evaluated the efficacy of a water-soluble contrast enema (WCE) in predicting anastomotic healing after a low anterior resection (LAR). METHODS Between January 2000 and March 2012, 682 consecutive patients underwent a LAR or an ultra-low anterior resection (uLAR) and were followed up for leakage. Clinical leakage was established by using physical and laboratory findings. Rad...
Leakage is a major safety issue that, if left unchecked, may result in dam failure by various mechanisms. There is enormous pressure on dam operators to repair leaks without significant delays. Frequently, the need to reduce the risk of failure or control water loss has led to costly remedial repairs that are planned and executed without a complete understanding of the problem. A lack of approp...
In drought stress conditions, besides the inhibition of water uptake, the plant nutrients availability and uptake are also limited. Proper nutrition is known as a management procedure for plant production under different environmental-stress conditions. Generally, the combined effects of drought and deficiency of potassium and zinc on plant water content and some physiological parameters reduce...
One of the negative effects of water stress on growth and crop production is micronutrient uptake reduction by plant root. Therefore, to evaluate the effect of foliar application of Fe and Zn on some physiological and morphological characteristics of red bean (Akhtar cultivar) under drought stress this experiment was designed as a split plot in a completely randomized block design with three re...
Drought has adverse effects on plant growth and production. Plants respond to drought stress through biochemical and physiological processes. In the present study, physiological responses of two cumin (Cuminum cyminum L.) ecotypes including Ravar and Gonbad, which belong to dry and sub-humid regions of Iran, respectively, were evaluated in a split-plot factorial experiment with three replicatio...
Development of carbon free diffusion layer for activated carbon air cathode of microbial fuel cells.
The fabrication of activated carbon air cathodes for larger-scale microbial fuel cells requires a diffusion layer (DL) that is highly resistant to water leakage, oxygen permeable, and made using inexpensive materials. A hydrophobic polyvinylidene fluoride (PVDF) membrane synthesized using a simple phase inversion process was examined as a low cost ($0.9/m(2)), carbon-free DL that prevented wate...
We have employed atomic-scale molecular dynamics simulations to address ion leakage through transient water pores in protein-free phospholipid membranes. Our results for phospholipid membranes in aqueous solution with NaCl and KCl salts show that the formation of transient water pores and the consequent ion leakage can be induced and be driven by a transmembrane ionic charge imbalance, an inher...

To investigate the effects of salicylic acid (0, 10, 15 and 20 µM) on some physiological characteristics of Fenugreek (Trigonellafoenum- graecum L.) under drought stress (0, -3 and -6 Bar) a Factorial experiment based on completely randomized design with three replications was employed in research greenhouse of Shahid Bahonar University of Kerman in 2012 growing season. Results show...
