Kyrgyzstan’s Manas epos millennium celebrations: post-colonial resurgence of Turkic culture and the marketing of cultural tourism
No full textThe paper addresses the symbolic nature of the Manas epos and its influence on both the unification of Kyrgyzstan and the enhancement of the country's national and Turkic identity. The case of the Manas epos millennium celebrations event is then used to illustrate the relationship between the uses of the Manas 'legend' in the construction of a national identity and in the positioning of the cultural tourism product. The paper subsequently assess the potential usefulness of the Manas epos in the creation of a destination image for Kyrgyzstan and in the positioning of Kyrgyzstan in the global tourism marketplace
Optimizing Cr(VI) reduction to Cr(III) using Pd-CNTs nanocatalyst: kinetic Monte Carlo simulation and experimental design insights
No full textAbstract In this investigation, we explored the kinetics of Cr(VI) reduction to Cr(III) on carbon nanotube decorated with palladium (Pd-CNTs) nanocatalyst, using formic acid as the reducing agent. This study has been bone utilizing kinetic Monte Carlo simulation and experimental design methods. The mechanism and kinetic parameters of this reaction are provided. The effect various factors such as reaction time, pH level, dichromate (Cr2O7 2−) concentration, and formic acid concentration on Cr(VI) reduction was studied. Concentrations of HCOOH and Cr2O7 2− were identified as the crucial variables, while the HCOOH concentration has the most significant impact. Positive influences on Cr(VI) reduction were observed with increasing pH level and HCOOH concentration. Reaction time positively affects on Cr(VI) reduction efficiency. However, the concentration of Cr2O7 2− showed an increasing effect up to a threshold, negatively impacting the efficiency. The optimal conditions (Reaction time = 60 min, pH = 4.5, [Cr2O7 2−] = 5.05 × 10−3 M, and [HCOOH] = 0.95 M) for Cr(VI) reduction. At optimal conditions, the Cr(VI) reduction efficiency was obtained to be 100%

No full textTheoretical insights in catalytic reduction of Cr(VI) using Pd/Fe nitrogen doped mesoporous carbon
No full textAbstract This study explored the kinetics of Cr(VI) conversion into Cr(III) by sodium formate on a nitrogen-doped magnetic mesoporous carbon material infused with Pd and Fe nanoparticles. This study provides the mechanism, kinetic parameters, and optimal conditions for Cr(VI) reduction by employing kinetic Monte Carlo simulations and response surface methodology. It has been proposed that Cr(OH)6 is an intermediate in this reaction. The influences of various factors, such as the initial concentrations of sodium formate and dichromate, pH, and reaction time, on the reaction efficiency were also investigated. These results suggest that the ideal conditions for Cr(III) synthesis involve a synergy of low pH and dichromate levels, a heightened sodium formate concentration, and prolonged reaction periods. The optimal conditions for Cr(III) production on Pd/Fe-NMC surface are pH = 1.37, Reaction time = 161.30 min, Cr2O7 2− initial concentration = 8.3 × 10−4 M, and HCOONa initial concentration = 1.02 M. Under the proposed optimal conditions, the Cr(VI) reduction efficiency of the Pd/Fe-NMC surface was 99.82%
General form of a cooperative gradual maximal covering location problem
No full textAbstract Cooperative and gradual covering are two new methods for developing covering location models. In this paper, a cooperative maximal covering location–allocation model is developed (CMCLAP). In addition, both cooperative and gradual covering concepts are applied to the maximal covering location simultaneously (CGMCLP). Then, we develop an integrated form of a cooperative gradual maximal covering location problem, which is called a general CGMCLP. By setting the model parameters, the proposed general model can easily be transformed into other existing models, facilitating general comparisons. The proposed models are developed without allocation for physical signals and with allocation for non-physical signals in discrete location space. Comparison of the previously introduced gradual maximal covering location problem (GMCLP) and cooperative maximal covering location problem (CMCLP) models with our proposed CGMCLP model in similar data sets shows that the proposed model can cover more demands and acts more efficiently. Sensitivity analyses are performed to show the effect of related parameters and the model’s validity. Simulated annealing (SA) and a tabu search (TS) are proposed as solution algorithms for the developed models for large-sized instances. The results show that the proposed algorithms are efficient solution approaches, considering solution quality and running time
The combination of fluoxetine and environmental enrichment reduces postpartum stress-related behaviors through the oxytocinergic system and HPA axis in mice
No full textGestational stress can increase postpartum depression in women. To treat maternal depression, fluoxetine (FLX) is most commonly prescribed. While FLX may be effective for the mother, at high doses it may have adverse effects on the fetus. As environmental enrichment (EE) can reduce maternal stress effects, we hypothesized that a subthreshold dose of FLX increases the impact of EE to reduce anxiety and depression-like behavior in postpartum dams exposed to gestational stress. We evaluated this hypothesis in mice and to assess underlying mechanisms we additionally measured hypothalamic�pituitary�adrenal (HPA) axis function and brain levels of the hormone oxytocin, which are thought to be implicated in postpartum depression. Gestational stress increased anxiety- and depression-like behavior in postpartum dams. This was accompanied by an increase in HPA axis function and a decrease in whole-brain oxytocin levels in dams. A combination of FLX and EE remediated the behavioral, HPA axis and oxytocin changes induced by gestational stress. Central administration of an oxytocin receptor antagonist prevented the remediating effect of FLX + EE, indicating that brain oxytocin contributes to the effect of FLX + EE. These findings suggest that oxytocin is causally involved in FLX + EE mediated remediation of postpartum stress-related behaviors, and HPA axis function in postpartum dams. © 2021, The Author(s)
Implementing Antoine Berman's Theory of Deconstructive Trends in Translating Novels from Persian into Arabic: The Case Study of Two Translations of The Blind Owl
No full textAntoine Berman, a theorist in the field of translation studies, believes that some events happen in translation, especially prose translation, which could be categorized under thirteen titles. He believes that using negative analysis method, we can examine these thirteen categories in translated texts. Implementing this theory on two Arabic translations of Sadegh Hedayat's novel , TheBlind Owl, by Al-Dasughi and Adas, we try to prove that this theory can be considered as universals of translation. The analysis of these translations shows that all the thirteen titles exist in the translated novel except for beautification. The reason for not achieving beautification in the translation of this novel is because it is a modern prose; since the objective of the author and thus the translator of the novel is far from beautifying and using stylistic devices. Finally, despite some drawbacks in implementation, the theory has a relatively efficient framework for reviewing translated texts and can be considered among universals of translation
Differential modulatory actions of GABAA agonists on susceptibility to GABAA antagonists-induced seizures in morphine dependent rats: Possible mechanisms in seizure propensity
No full textAn investigation of the role of domestic courts in international commercial arbitration in iranian law
No full textThe fact that almost every legal system considers a specific basis for the intervention of state courts in the process of arbitration has resulted in uncertainties and criticisms regarding the independence of the so called quasi-judicial dispute settlement of arbitration as well as its effectiveness and successfulness. The author of the present study has made an effort to on the one hand separate the cases of assistive intervention of civil courts in the process of arbitration from the regulatory intervention cases and on the other hand, investigate the form-related and essential limitations of the enforcement of judicial supervision by the courts
