Cucumber is a warm season crop that suffers from chilling injury at temperatures below 10°C. In recent years, jasmonates have been used for reduction of chilling injuries in plants. An experiment was, therefore, conducted to test whether methyl jasmonate (MeJA) application at various concentrations (0, 0.05, 0.1 and 0.15 mM) through seed soaking or foliar spray would protect cucumber seedlings,...
Seed pretreated with plant growth regulators can improve germination parameters, growth, and yield of crops. Thus, in two greenhouse and field experiments, effects of seed treatment with 0.1 mM salicylic acid (SA), 1µM methyl jasmonate (MJ), 1.5% humic acid (HA), and water (as Control) on germination parameters, seedling growth, and also growth and fruit yield were studied. In the first experim...
Selection of frost tolerant cultivars and understanding the mechanisms of frost hardiness could help to improve freezing resistance in olive plants. Olive cultivars may differ in frost hardiness due to differential survival of specific organs. The aim of this study was to screen different olive cultivars based on their stomatal density and metabolic modifications under cold conditions. The ‘Zar...
Economic models suggest that in many cases, market leakage rates of greenhouse gas abatement reach the two-digit percentage range. Consequently, the Marrakesh Accords require Clean Development Mechanism (CDM) projects to account for leakage. Despite this, most project proponents neglect market leakage for their project, because the influence of an individual project on market prices seems to be...
Peach is a highly corrosive fruit with a short shelf life (less than 7 days at room temperature)susceptible to diseases, pathogens and physical damage. The storage or marketable life ofhorticultural crops can be extended by various treatments applied to them after and/or beforeharvesting. Fruits are usually treated with a range of materials [(e.g. salicylic acid (SA)] to...
Introduction: Due to its simplicity, fast response and high reliability, ion chamber detectors are one of the most suitable dosimetry instruments for X and gamma rays. The dosimeter of photon beams, which used in radiotherapy centers, requires high accuracy and should pass requirements of IEC 60731 standards. About 80 percent of the IEC 60731 standard tests such as stabil...
Power dissipation has become one of the major concerns of VLSI circuit design with the rapid launching of battery operated applications. In high performance designs, the leakage component of power consumption is comparable to the switching component. This percentage will increase with technology scaling unless effective techniques are introduced to bring leakage under control. In this paper, an...
The design concept and dosimetric characteristics of a new applicator system for intraoperative radiation therapy (IORT) are presented in this work. A new hard-docking commercial system includes polymethylmethacrylate (PMMA) applicators with different diameters and applicator end angles and a set of secondary lead collimators. A telescopic device allows changing of source-to-surface distance (S...

the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...
