peach (prunus persica l. batsch.) is produced in most areas of iran, where flowering is hindered by temperature. using plant growth regulators to delay bloom is a suggestive measure to avoid frost damage. the objective of this study was to determine the effects of methyl jasmonate (mj) and salicylic acid (sa) on peach bloom delay and yield.  this study evaluated the applications of mj 0 (contro...

Background. Sleep is assumed to be a critical factor for human physiological and cognitive function. Lack of sleep is a common condition in daily life. Objectives. The purpose of this study was to evaluate the effects of 24-hour sleep deprivation on cognitive and motor skills in university students. Methods. The participants were volunteers that consisted of 290 male students aged 19-25 years...

Results of a high-speed 10-stage axial-flow compressor test involving overall compressor and individual stage performance while stalling and operating in quasi-steady rotating stall are described. Test procedures and data acquisition methods used to obtain the dynamic stalling and quasi-steady in-stall data are explained. Unstalled and in-stall time-averaged data obtained from the compressor op...

We present an electron holography technique to acquire an interferogram, that is, cosine image of phase distribution. The interferogram is constructed by shifting the specimen in one direction with a stage-scanning system and acquiring line intensities of holograms. Taking line intensities eliminates the carrier fringes in the holograms and yields the interferogram. Under phase object approxima...

To study the effect of puberty on the relationship between serum 25-hydroxyvitamin D (25(OH)D) and parameters of insulin kinetics in obese Asian-Indian children. Material and Methods. The study population included 62 obese Asian-Indian children and adolescents in the age group of 6-17 years. Blood glucose, serum insulin, and serum 25(OH)D were measured. Total body fat was measured by dual energ...

the aim of this study is to investigate the role and structure of motivation in learning a foreign language in order to introduce the model ofinformation processing as a new approach and scale to evaluate themotivation of foreign languages.for this purpose,two hundred and fifty participant employees ofthe iranian oil terminals company enrolled in the english language training courses were selec...

In this study, the methods which can detect basic physical movements of a person (downward, upward, sitting, stop, walking, running) from inertial sensor data are evaluated. The performances classical and current approaches to map IMU activity classes were compared. A three-stage study was carried out for aim: 1) acquisition; 2) creating training/test sets; 3) construction classification networ...
