The scale-invariant burstiness or self-similarity has been found in real networks. Relation between self-similarity and networks and/or system parameter is the center of discussion in the context of application layer. This self-similarity is caused by the file size of Web servers or the duration of user sessions. In addition, self-similar burstiness has been characterized by the transport layer...

the aim of this study was to compare the performance of analogy (implicit),explicit and discovery learning in the retention and transfer of a topspin shot underpsychological pressure. for this purpose, 36 volunteer high school students wererandomly allocated to three treatment conditions: explicit, analogy, and discoverylearning. after performing 300 trials in the acquisition phase, an immediat...

the impact of climate change in the next few decades will increase risks of wheat production under dryland conditions. therefore, it is important to find cultivars that are tolerant to these conditions and can provide reasonable yield under future climates. radiation use efficiency (rue) is the key factor determining the crop yield and is related to crop biomass and leaf area index (lai). t...

Steel pipes with circular cross-sections are usually used in cooling panels of electric arc furnaces. In the present study pipes with square cross-sections under equivalent conditions were used to obtain more information on the possibility of increasing the heat transfer and cooling efficiency. The results showed increased efficiency of the square pipe compared to the circular cross-section pip...

In this study carburizing and boronizing processes were applied to powder metallurgy steel specimens and the mechanical and tribological properties of the substrate and coatings were evaluated under various process conditions. The specimens, made from industrial test pieces, were carburized in a powder pack for a duration of 2-5 hrs at 850-950 ˚C. Similar specimens were pack boronized for 4 hr...

In this study, oxidation of some 3,5-diacyl or 3,5-diester 1,4-dihydropyridines to corresponding pyridine derivatives using sodium bromate in the presence of NH4Cl, NaHSO4 and Bu4NHSO4 under thermal conditions has been investigated. The yield and structure of formed products is similar under all conditions; however, the reaction is accelerated in the presence of Bu4NHSO4 and NaHSO4. In addition...

in order to evaluate chemical mutation on cultivar mahali tarrom’ in salt stress, seeds of rice cultivar ‘mahali tarrom’ were treated with two chemical mutagens, ethyl methane sulfonate (14 mm) and sodium azide (two mm). in second generation, appropriate plants for economically important traits have been selected. seeding of selected plants were tested under salt stress in third generation usin...

Pulverised coal injection (PCI) is used in ironmaking to replace expensive and energy intensive coke with coal, reducing overall costs greenhouse gas emissions. As the making process removes some of sulphur present utilisation PCI results admission greater levels into blast furnace. The increased could potentially lead an increase usage related hot metal removal processes. In increasingly volat...
