This research was conducted to study of the essential oil content, some morphological parameters, crop evapotranspiration (ETc) and crop coefficient (Kc) of Summer Savory (Satureja hortensis L.) in the west of Iran (Khorramabad region) in 2017. Weighing Lysimeters (25 cm diameter and 30 cm height) were used to measure important morphological parameters, t...
The effects of hot air temperature (40, 50 and 60 oC) and Radiation Intensity (RI) (0.21, 0.31 and 0.41 w/cm2) on the response variables (drying time, Head Parboiled Rice Yield (HPRY), color value and hardness)) of parboiled rice were investigated. The drying was performed using hybrid hot air–infrared drying. The optimization of drying variables and the relationship b...
in this paper, the output power behavior of the wave-guide cw-co2 laser versus efficient parameters of laser performance was investigated. the output power variation versus the discharge current, the pressure and the gas mixture ratio was studied and optimized. the maximum output powers of 6 and 14.5 w were respectively obtained at operating pressures 78 and 50 mbar in two tubes of 3 mm same di...
population dynamic parameters of red mullet, mullus barbatus (n=592) caught by trawlers operating in arzew gulf (algeria) in the western mediterranean were studied. samples were collected between february 2013 and january 2014. females ranged from 10.9-23.2 cm in total length and 12-149.2 g in weight whereas males length was comprised between 12.6 and 19.7 cm and weight between 21.3 and 99.9 g....
The present research aimed to study some biological parameters of Alosa caspia Caspian Sea in the southeast Mazandaran Province in 2014-2015. A total of 600 samples were examined during this period and data were analyzed using SPSS software. The results showed that the mean fork length and total weight of A. caspia was 24.22 ± 54.2 cm and 167.63 ± 63.59 g, respectively, and the length and weig...
Rainbow trout is one of the 100 exotic invasive species in the world, and the biological characteristics of evaporated specimens of marine cages on the coast of Mazandaran including sex ratio, length and weight relationship, and growth are necessary. In order to study the rainbow trout growth parameters, 90 specimens of this species were collected from October 2017 to May 2019 from catching bon...
در این تحقیق، خواص اپتیکی غیرخطی بلور مایع نماتیک آلائیده با رنگینه آزو مورد بررسی قرار گرفته است. مقدار و علامت ضریب شکست و ضریب جذب غیرخطی بلور مایع نماتیک آلائیده با رنگینه آزو دیسپرس قرمز 2 توسط روش جاروب اندازه گیری شده است. در این مقاله، اندازه گیری ها توسط لیزر پیوسته نئودیم یگ با طول موج nm532 انجام شده است. تاثیر جهت گیری اولیه ملکول ها بر روی خواص غیرخطی بررسی شده است. ضریب شکست غیرخط...
