In this study, thermal performance of the collector with analytic and quasi-dynamic method is evaluated based on energy balance equations for each part of the U-pipe evacuated tube solar collector. Using this approach, effect of different parameters such as tube size, overall heat loss coefficient, absorber tube absorptivity, mass flow rate and air layer thermal resistance on thermal performanc...
The external morphology of the heads of adult male and female Cixiopsis punctatus (Matsumura) (Hemiptera: Fulgoromorpha: Tropiduchidae) was studied using scanning electron microscopy. Eleven types of sensilla or sensory organs were identified: trichoid sensilla on the pedicel, scape, maxillae, and labium; campaniform sensilla on the antennal pedicel, antennal scape, maxillae, and labium; plate ...
objective: the purpose of this study was to evaluate and compare the effect of storage time and conditions on dimensional stability of acrylic patterns. materials and methods: in this in vitro study, a cylindrical shaped metallic post-core was fabricated. impressions were made from this metallic model and 30 samples were prepared with duralay acrylic resin. the specimens were divided into three...
To evaluation of genetic parameters of rooting traits in 50 doubled haploid barley lines, a factorial experiment based on CRD was carried out at the agronomy lab of the Zanjan University Analysis of variance showed significant differencesfor all rooting traits:material transfering speed, germination percent, angle, diameter, fresh and dry weight, surface area, cumulative length, the length of t...
