Risk assessment of a transgene is one of the key steps in genetic transformation. Hence, in order to use cryIAc gene for production of transgenic plants, a library and in-silico research was performed to confirm safety of the gene for human comsumption, animal feed and environment. In the first step, the molecular mechanism of action of the CryIAc protein and its specific receptors in the midgu...
Presence of invasive species on rangelands is a degradation sign. The aim of this study was to evaluate the effects of invasive species Leucanthemum vulgare Lam. on the structural and functional characteristics of Fandoghlou rangelands in the Namin county of Ardabil province. The model used for sampling was the stratified random systematic. Two main sites with the presence and absence of L. vul...
the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...
background and objectives: there are studies that support music and singing as appropriate developmental care for premature infants, thus, we conducted this study to investigate the physiological and behavioral responses of premature infants to quran recitation, lullaby music and silence. methods: in a randomized controlled trial (2011-2012),120 premature infants in the neonatal unit (nnu) at i...
J. Econ. Entomo!. 81(2): 634-640 (1988) ABSTRACT Differences in susceptibility to damage by Thrips tabaci Lindeman and the lepidopteran pest complex (Plutella xylostella (L.), Artogeia rapae (L.), and Trichoplusia ni (Hiibner)) were documented and analyzed for fresh market and experimental cabbage varieties. Patterns of resistance to damage were different for Lepidoptera and T. tabaci. The comm...
To study the effects of plant densities and planting orientation on the seed and forage yield of sorghum, an experiment was conducted at Hossein- Abad – Shahcal village –90 kilometers south of Bam-in 2002. The experiment was a factorial with randomized complete block deisgn and three replications. The treatments were: orientation with three levels (South-North, East – West, Northeast – Southwes...
bacteria of the genus azospirillum are well known as plant growth promoting rhizobacteria. the ability to synthesize phytohormones is considered one of the most important mechanisms to promote plant growth and is widely distributed among plant-associated rhizobacteria.the most important phytohormone produced by azospirillum is the auxin indole-3-acetic acid, with the l-tryptophan as the precurs...
Ovipositional preference and larval survival of the diamondback moth, Plutella xylostella (L.), were compared among cabbage, Brassica oleracea L. variety capitata; glossy collards, Brassica oleracea L. variety acephala; and yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata in different treatments of planting density, host plant age, intercropping, and water stress in 2003 and 2004. P. x...
In order to study the effects of rate and time of nitrogen application on vegetative characters, i.e., yield and yield components of rice (Zayandeh-rood variety), an experiment was conducted at Isfahan University of Technology research farm during summer 1996. Four N rates including (60, 90, 120 and 150 KgN/ha) and four splitting form (1- all N applied before transplanting 2- 1/3 N applied befo...
a study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (ocimum basilicum l.). the research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. the experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...
