To investigate the effects of planting density and organic fertilizers on the yield traits of Satureja spicigera (K.Koch) Boiss. under the Kermanshah rainfed conditions, an experiment was conducted as a split-plot based on complete randomized block design (CRBD) with three replications in Kermanshah Agricultural and Natural Resources Research Center in 2016-2020 crop years. The main factor and sub-factor were fertilizer (rotten cow manure, enriched straw, and field soil (control)) and plant density (2.66, 4, and 8 plants.m-2), respectively. To have the desired densities, plants were grown with a distance of 50 cm between the rows and 25, 50, and 75 cm on the rows. The results showed that the traits including diameter, height, canopy area, fresh and dry weight of plant, fresh and dry yield per hectare, and essential oil yield per hectare were significantly different between the years, plant densities, and fertilizer treatments. The highest fresh yield (3639.3 kg.ha-1) was obtained in the rotten cow manure+ high plant density treatment and the highest dry yield (2105 kg.ha-1) and essential oil yield (72.59 kg.ha-1) in the enriched straw+ high plant density one. The results showed that the best fertilizer and plant density treatment for S. spicigera was straw enriched with ammonium sulfate and 8 plants.m-2.

Genetic variation was investigated for the number of 15 Agropyron cristatum accessions using the number of 15 ISSR primers. The number of 12 primers can be scored. The ISSR primers produced the number of 71 bands. The polymorphism has been observed for the number of 66 bands. The primers of IS1 and UBC857 presented the highest number of bands, i. e. eight bands; while the IS7 and UBC869 showed the lowest number which is only three bands. The primer of UBC844 were showed the lowest polymorphism percentage (83.33%) and IS2, IS6, IS7, UBC848, UBC865, UBC868 and UBC869 had the highest polymorphism percentage (100%). The polymorphism percentage average was 94.15%. The average of bands was 5.92 in each primer for 15 genotypes and the average of polymorphic bands was 5.50. IS6, UBC865 and UBC869 can determinate genetic distance of genotypes better than other primers. The genotypes of G4 with G2 had the most similarity and G1 with G8 had the lowest similarity. The results of UPGMA cluster analysis based on Jacard's similarity coefficient were fallen the genotypes in three groups, which confirmed by principal coordinate analysis and molecular variance analysis. The genetic diversity of the populations was matched based on the studied marker with their geographic distribution, and the populations of Gorgan and Isfahan were similar, which, on the other hand, showed greater distance with Karaj populations.

Motivation and its conditions are among the most important environmental factors affecting learning. Non-generic feedback implies that performance is malleable, while generic feedback implies that task performance reflects an inherent ability. Therefore, each one has different motivational effects. This quasi-experimental study examined the motivational effects of generic and non-generic feedback on motor learning in twelve-year-old girls. The participants were 40 female students randomly assigned to two different groups-generic feedback (G-FB) and non-generic feedback (NG-FB). The task required participants to perform low kicks at a squared target area consisting of a piece of cardboard (measuring 50 cm wide and 50 cm high) attached to a wall and touching the ground, and placed at a distance of seven meters from the participants. Accuracy scores were analyzed in 2 x 4 (group*blocks) analysis of variance with repeated measures for the first experimental phase, and in 2 x 2 (group*blocks) analysis of variance with repeated measures for the negative feedback phase and the retention test. The findings show that both groups performed with similar accuracy across practice blocks. But on the second phase and no-feedback retention test, the NG-FB group indicated higher accuracy than the G-FB group. Therefore, it seems that that children’s motor performance, learning and motivation can be affected by the kind of augmented feedback provided during practice.

Students with attention deficit hyperactivity disorder suffer from a variety of cognitive and behavioral problems. Research shows that language plays a role as an intermediary in cognitive and behavioral control in this disorder. The present research aimed at comparing the verbal performance in different kinds of categories of this disorder and also comparing it with normal students. The sample of this research consists of 240 people. 180 individuals (90 girls and 90 boys) were selected from among the students with attention deficit hyperactivity disorder who had referred to the education department-affiliated clinic in the city of Shahriar in academic year 2017-2018 and the subjects of the control group were randomly selected from among the normal students (30 girls and 30 boys) and the data were collected using Wechsler's neuropsychological scale. The results showed that students with attention/ hyperactivity disorder generally have a lower verbal comprehension than normal students; moreover, it was found that from among the three categories of this disorder, the hyperactive-impulsive group showed the significantly lowest performance. Accordingly, it can be concluded that verbal comprehension plays an important role in the regulation of students' cognitive and behavior and should be emphasized in therapeutic interventio.

In this study, thermal Casimir-Polder potential is calculated for an atom in the presence of a dielectric sphere using the formula given in terms of the Green’s function. Then, the limiting cases of large and small sphere are investigated. In the limiting case of a large sphere, the formula of thermal potential for an excited atom in the presence of a dielectric half-space and then a perfectly conducting plate is obtained. The limiting case of the small sphere together with the proper replacement of its electric response by the polarizability of a second atom results in the thermal van der Waals interaction potential between the two atoms.

This paper develops an MILP model, named Satisfactory-Green Vehicle Routing Problem. It consists of routing a heterogeneous fleet of vehicles in order to serve a set of customers within predefined time windows. In this model in addition to the traditional objective of the VRP, both the pollution and customers’ satisfaction have been taken into account. Meanwhile, the introduced model prepares an effective dashboard for decision-makers that determines appropriate routes, the best mixed fleet, speed and idle time of vehicles. Additionally, some new factors evaluate the greening of each decision based on three criteria. This model applies piecewise linear functions (PLFs) to linearize a nonlinear fuzzy interval for incorporating customers’ satisfaction into other linear objectives. We have presented a mixed integer linear programming formulation for the S-GVRP. This model enriches managerial insights by providing trade-offs between customers’ satisfaction, total costs and emission levels. Finally, we have provided a numerical study for showing the applicability of the model.

Solar collector, the first part of each solar dryer system, is important for industrial and agricultural purposes. The final objective of any solar system is to maximize its output. The energy analysis is excellent complementary thermodynamic tools for this purpose. In the present study, a comprehensive thermodynamic model for energy analysis of a double pass solar air heater has been carried out. Energy balance equations have been investigated for all components of the solar air heater including insulation, lower channel air stream, absorber, upper channel air stream and glass cover. The main object of this research was to find energy efficiency of a double- pass solar air heater for all over the year of Yazd Province in Iran. Moreover, the effect of inlet length and inlet width of collector on outlet temperature of solar air heater was studied. The results of the simulation showed that the maximum monthly average energy efficiency of the solar air heater is 32.41% in January with 145solar radiations. It is attributed to the fact that the inlet length of solar air heater has a positive effect on the increment of outlet temperature of top and bottom channel and efficiency of system, also the inlet width of solar air heater has negative effect.

This opinion exist that basement of the Sanandaj-Sirjan Zone was cratonized during Cimmerian and Laramide Orogenic phases and so, therefore it is considered as an aseismic (or low-sesimicity) zone. The Shahreza area in the central part of the zone is ed as a case study area for investigation on seismicity and recent movements and verifying of this hypothesis. We used Geoinformatic techniques (including: Remote Sensing, GIS and field surveying methods) in this research to detect the structures of the area and their kinematics, to locate earthquake foci, to find neotectonic evidences of active faults, and proofs for high seismicity of the area. Our results shows that the Shahreza fault (and Dehaghan fault located in southwest of study area) having a dextral strike-slip mechanism is the main structural trend in the area. This fault zone is truncated and offset by the Nosratabad fault (with strike N50-70E and sinistral strike-slip mechanism). In the intersection area of these main trends, many earthquake foci (with strike-slip focal mechanism) are located. Other than several earthquakes, neotectonic evidences for fault activity are are observed in the Shahreza area.

In order to study yield and physiological traits of five annual medic species namely M. rigidula, M. turbinata, M. orbicularis, M. radiata and M. minima under irrigated conditions, a field study was conducted based on a complete randomized block design with three replications in Islamabad-Gharb station, Kermanshah, Iran. Water requirement estimated by Penman-Monetith method and CROPWAT package using local climatological data based on 90% of irrigation efficiency. Data analysis showed a significant difference (P<0.05) between the species for leaf water content, relative water content, growth period, forage yield and plant height traits. In contrast, there were no significance differences for leaf stem ratio, stems per plant and chlorophyll fluoresce. M. rigidula showed better performance for majority of the traits, especially forage yield, followed by, M. orbicularis and M. minima. M. turbinata and M. radiata had lowest forage yield and field performance. Cluster analysis of the data by Ward method confirmed results of the data analysis. There was a positive significant correlation coefficient between relative water content and growth period with forage yield at 1% probability. Plant height and chlorophyll fluoresce showed positive and significant correlation with forage yield at 5% probability. Finally, according to the results, M. rigidula is recommendable for forage production under irrigated condition of the province.
