objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
evaluation of morphological variations in 70 genotypes of seven accessions of thymus caramanicus jalas.growing in central iran was carried out, for determining valuable characters for future breeding programs and medicinal purposes. in this study 30 quantitative and qualitative characters were evaluated. the results revealed great variabilities of important traits among populations. results of ...
this study was performed to evaluate relationships among morphological traits and use of the traits to describe iranian cannabis accessions. results of the anova for the measured traits excluding the number of lateral inflorescent, displayed significant differences among accessions. the lowest plant heights were observed in sero and saqez (respectively 81.20 and 78.80) and the highest values we...
This experiment was carried out to investigate the effect of polyamines on growth, flowering and corm production of ‘Golden Wave’ and ‘Blue Sea’ cultivars of freesia. For this purpose, freesia plants were sprayed at 35, 70 and 100 days after planting with concentrations of 0.5 and 1 mM of putrescine, spermidine and spermine and distilled water (control). The factorial ex...
in order to evaluate the allelopathic potential of sunflower (helianthus annus l.) organs on germination and growth of dodder (cuscuta compestris l.), series studies were conducted in three separate experiments; as factorial based on completely randomized design (crd) with three replications for each experiments. first experiment was conducted in petri dishes and consisted of sunflower organs a...
the experiment was performed to evaluate the morphological, phenological and yield aspects of two different echinochloa species, including barnyardgrass (e. crus-galli) and watergrass (e. orizoides) as a new-introduced weed species. the study was conducted as a 2-years pot-experiment under outdoor condition at rice research institute of iran (rrii) in rasht. the results demonstrated that; time ...
The aim of investigation was to determine the effects of aspect (north and south) on some morphological [plant height (cm), number of stems per plant, main stem diameter (mm), number of leaves per main stem, petiole length (cm), leaflet length (cm), leaflet width (cm), leaf: stem ratio] and chemical [crude protein (%), crude cellulose (%), calcium (%), phosphorus (%), potassium (%) and magnesiu...
