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 ...
In this research, based on the observed data of Class A pan evaporation and application of non-linear regression (NLR), artificial neural network (ANN), neuro-fuzzy (NF) as well as Stephens-Stewart (SS) methods daily evaporation of Kerman region was evaluated. In the cases of NLR, ANN and NF methods, the input variables were air temperature (T), air pressure, relative humidity (RH), solar radia...
the purpose of this study is to investigate the relationships between teachers’ immediacy behaviors and iranian students’ willingness to talk in english classes. analysis of the results from willingness to talk scale represents a relatively high level of willingness to talk in english classrooms among iranian language learners. the total mean score of students’ willingness to talk was 66.3 ou...
To investigate the physiological responses of sunflower (Helianthus annuus L., Alstar hybrid) to water stress under different levels of zinc fertilizer, an experiment was conducted at the Isfahan Agricultural Research Center, Isfahan, Iran, during 2008 and 2009 using a randomized complete block design within a split plot layout with three replications. Five irrigation treatments used in thi...
this study was conducted to determine the effects of different water and nitrogen application levels on drip-irrigated tomato plants. the amount of water usage was based upon the pan evaporation from a screened (class “a”) evaporation pan. the treatments consisted of two irrigation intervals (i1= 5 days and i2= 10 days), three plant-pan coefficients (kcp1= 0.50; kcp2= 0.75 and kcp3= 1.00) and t...
Evaporation is one of the important and effective processes in water cycle that causes loss of large volumes of lake and Abbandan’s water wich its measurement has great importance in water resources planning. In this research, the amount of evaporation in six months (from April to September in 2016) from the free surface of Dazmirkande Abbandan located at Mazandaran Province has been measured b...
in semiarid regions of iran, one of the crop production management methods is delayed irrigation after emergence. this is due to simultaneous water requirement of cereal and spring season crops. a field study was conducted in kabootarabad research station to investigate the effect of delayed irrigation on root yield, quality and growth trend using a rcb with four replications. the irrigation tr...
The two-location field experiment was conducted to study the possible alleviation of droughtstress effects on red bean by ultrasonication and 24-epi-brassinolid. Locations were AgriculturalResearch Center in Shahrood, Iran and the other in bean farm, 40 km off Shahrood city in 2015.Experiment factors included irrigation of main plots at three levels of normal irrigation (60 mmevaporation from e...
This experiment was conducted to evaluate drought tolerance of different safflower genotypes as a split- plot experiment based on a complete block design with three replications. The main plot was irrigation at three levels on the basis of 70, 120 and 170 mm cumulative evaporation from Class A pan and ten different genotypes of the safflower were considered as subplots. Results of analysis of v...
In order to study the effects of foliar application of potassium (K) and boron (B) and dificit irrigation treatments on quantitative and qualitative traits of sugar beet (Beta vulgaris L.), a split plot experiment was conducted based on randomized complete block design with three replications in the Research Field of Shahrekord University, Shahrekord, Iran, in 2019. The main plots were allocate...
