1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
pistachio nut is one of the most important export crops in iran. for prevention of rancidity and to ensure good quality, pistachio must be harvested in a short time and be prepared for drying in 24h.the ohadi variety of iranian raw dry pistachio nuts was selected for the experiments. instrumental hardness and sensory characteristics of pistachio nuts such as: flavor , texture and total acceptan...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
effect of different ratios of sucrose to fruit concentrate (orange and sour cherry), level of cacl2 (0-2%) and storage time (0-90 days) on physicochemical properties of candied apples were investigated using of a combined design. different quality indices such as total sugars content, ascorbic acid, color attribute (chroma) and overall acceptance were modeled and then multiobjective optimizatio...
regarding the unique properties of camel milk, it can be used as a nutraceutical product. in this study, the effect of different variables on the quality characteristics of synbiotic yoghurt made from camel milk was studied. independent variables (all in three levels) in this study were: β-glucan (prebiotic agent) 0 - 1 - 2%, fat content 0 - 2.5 - 5%, the amount of probiotic bacteria 0.5 - 1 –...
The aim of this study was to evaluate the effect of levels of different vitamin E and selenium in tris extender on spermatozoa characteristics of Arabic ram. Semen collection was performed from 8 Arabic rams and mixed together. The mixed semen was divided in to 9 parts and after dilution with tris, different levels of selenium and vitamin E were added. This experiment was carried out in 3×...
In this study the effects of four quince harvesting times (at 10 - day intervals), in 2 years on fruit quality during cold storage for 5 months at 0˚C and 85% Relative Humidity were investigated. Fruits were picked from orchards in Flavargan region of Isfahan. Every month, pH, sugar content, acidity, TSS, tissue firmness of fruits were determined. Variance analysis shows that the effect of year...
