in this study the efficacy of intermittent and continuous drying processes on fissuring of hashemi and koohsar varieties was investigated. the fissuring of the kernels was assessed based on stress cracking index (sci). the experiments were carried out at drying and tempering temperatures of 30, 45 and 60 °c, drying durations of 20, 40 and 60 min, and constant tempering duration of 80 min. in co...
ABSTRACT We report the detection and analysis of a radio flare observed on 17 April 2014 from Sgr A* at 9 GHz using VLA in its A-array configuration. This is first reported simultaneous observation across 16 frequency windows between 8 10 GHz. cross-correlate lowest highest spectral centred 8.0 9.9 GHz, respectively, find light-curve lagging $18.37^{+2.17}_{-2.18}$ min behind light curve. time ...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Breastfeeding helps protect infants against some of the main causes of childhood mortality. This study aims to investigate the factors affecting breastfeeding duration in primiparous women referring to Tehran health centers. Mate...
Our goal was to establish a time of day and(or) interval from feeding that would avoid the refractory period after a somatotropin (ST) surge and optimize the responsiveness of horses to ST secretagogues. Two experiments were conducted with eight geldings conditioned to consume grain at 0800 and 1600 daily. In Exp. 1, during a 24-h period, these geldings averaged 3.2 +/- .3 pulses of ST with pea...
fruity teas are popular due to variety in sensory properties as well as their nutritional and therapeutical characteristics. recently, the worldwide researches related to fruity teas have been considerably developed. in this work, effects of fruit type (apple, quince and pear) and brewing time (10 or 20 min) on some nutritional properties (mg, fe and ca contents, sugars and protein percent) as ...
background: this study was planned to determine the relationship between bispectoral index (bis) during dental treatment and recovery conditions in children undergoing two regimes of anesthesia of propofol and isofl urane. materials and methods: in this single-blind clinical trial study, 57 4-7-year-old healthy children who had been referred for dental treatment under general anesthesia between...
Abstract Rose is an ornamental plant, which constitutes one of the leading cut flowers in world. The vase life Rosa hybrida L. truly short. We examined effect various temperatures and different time duration factors on postharvest longevity, some other physic-biochemical characteristics antioxidants activity. Fresh were treated by water with (23º, 42º, 47º, 52°C) (5, 10, 15, 20 min). Maximum (7...
In order to find the critical period of weed control, the best time of weed control beginning (i.e. herbicide application time), and the length of weed control period (i.e. herbicide persistency) in corn, field experiments were conducted in Bajgah and Kooshkak in Fars Province in 1995 using a randomized complete block design with 14 treatments and four replications. Treatments consisted of diff...
This randomized double-blind study compared the effects of: (1) saline infusion (C); (2) sufentanil alone (1.0 micrograms.kg-1) (S); and (3) low-dose sufentanil (0.5 micrograms.kg-1) in combination with lidocaine (1.5 mg.kg-1) (LS): on the cardiovascular responses to tracheal intubation and on postoperative ventilation as monitored by respiratory inductive plethysmography in day-care surgical p...
