Abstract In calcareous and saline soils, the adverse effect of some ions such as bicarbonate, boron, magnesium, and especially sodium, and the imbalance of nutrients’ concentrations are essential factors which reduce plant growth. A greenhouse experiment was conducted to study the effect of sodium (Na) and magnesium (Mg) on some growth traits and chlorophyll content of pistachio seedlings (cv....
Automated sphygmomanometers should be evaluated in field studies before being recommended for epidemiological use. In this study an automated sphygmomanometer, the Copal UA-231, was evaluated on the basis of duplicate blood pressure measurements, one with this machine and one with a Hawksley random zero machine, taken on 1536 participants in a health survey. The Copal-random zero differences ha...
in order to evaluate the effect of priming on germination of black cumin under different levels of salinity, a factorial experiment on base of completely randomized design was conducted with three replications. the main factors consisted of five levels of priming (osmopraiming with kno3 (1 and 3%), salicylic acid (sa) (0.2 and 0.5 mm) and a hydropriming)) and four salinity levels (zero, 75, 125...
To investigate the effect of manganese (Mn) and salinity on some growth traits and chemical composition of pistachio (Pistacia vera L.) seedlings, a factorial experiment was carried out with two factors of salinity (0, 75, 150, 225 and 300 mM NaCl) and Mn (0, 12, 24 and 36 µM Mn from MnSO4 source) as completely randomized design with four replicates, in greenhouse in perlite medium. Results sho...
Background and Objective: Nanoparticles have been introduced as novel antimicrobial agents because of their properties that are different from their bulk properties. Present study was aimed to investigate antimicrobial activity of silver nitrate and zinc oxide nanoparticles against three main bacteria responsible for nosocomial infections, S. aureus, P. aeruginosa and A. baumannii. Materials a...
to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...
To investigate the influence of humic acid on the amount of absorption and allocation of elements to different parts of Satureja khuzestanica under salinity stress conditions, a greenhouse experiment was done as factorial based on a randomized complete block design in four replications. Factors included humic acid (zero, 10, 20, 30 and 40 mg kg-1 soil), and salinity stress (zero, 25, 50, 75 and...
Objective: The main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. Methods: Drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [Hg], infrared radiation at power levels of 100, 150 and 200 W in the three repetition. Resu...
