Abstract
The present descriptive-analytic paper aims to investigate the distribution of the sentential negative marker in yes-no questions in Dashtestani dialect. As well as adhering to the beginning of the tensed main verbs and tensed auxiliary verbs in this dialect, the sentential negative marker is used immediately before the phrasal complements as well as the beginning of the negative yes-no questions. Relying on some theoretical and cross-linguistic pieces of evidence, the study examines the mechanisms beyond the optional behavior of this marker, together with its distribution in the hierarchy of the yes-no questions within the framework of the Minimalist Program. The findings of the study showed that the sentential negative marker is considered a ‘negative prefix’ in the position immediately preceding the tensed main verb as well as auxiliary verbs, and a ‘negative particle’ before the phrasal complements, each of them being generated in a different position. Consequently, in yes-no questions, the negative marker as a negative particle moves to the head of CP, satisfying, in this way, the Negative Criterion and yielding an interrogative interpretation. Lack of such a movement, on the contrary, renders the sentence ungrammatical.

Abstract
The narrative literature in Iran has always been one of the main sources of inspiration for many arts. In the meantime, the contribution of visual arts and drama is more than other arts. Accordingly, painting and cinema create the strongest link with literature, and in a fruitful effort, they offer valuable literary materials in a new garb, tailored to the needs of the day and in the form of a new media. Undoubtedly, in this transaction, the theme is also evolving due to the capabilities and features of the destination. Such developments, if intelligently and consciously recognized by the artist and the critic, are not only not considered shortcomings, but can also be added to the original value of the theme. With such a necessity and purpose in the present research, we try to examine the developments of the media and, of course, the sign of the narrative of the "passage of Siavash of Fire" from literature to painting.
This research is descriptive-analytic and based on Prop's pattern. The results indicate that the frequency of the role of the special features of the story varies according to the characteristics of the destination media (painting). In fact, the artist painter based on his artistic taste emphasizes the consequences of the story, which is not very frequent in Ferdowsi's narrative.

Abstract
This paper studies the short-term impacts of air pollutants on mortality rates in a range of diseases including cardiovascular, respiratory and digestive diseases, tumors and cancers. It uses daily data of suspended particulate matters (SPM), CO, NOx, and O3 in six metropolitan areas of Tehran, Ahvaz, Mashhad, Tabriz, Shiraz, and Esfahan during 2011-2015. In order to determine the impact of air pollution on mortality rate, both daily air pollution and its average over the past two weeks is used. In this research, no association was found between daily pollution and mortality rate. However, the results show that increasing CO in the past two weeks causes a significant increase in mortality rates

Abstract
The composites derived from the bioactive glasses, such as BG/polysulfone, have better mechanical properties than pure materials and their characteristics are closer to human bone. In this study, the unknown fracture behavior of 58s BG/PSF composite has been investigated. The extended finite element method (XFEM) was used, in order to model the fracture behavior of 58s BG/PSF composite with greater accuracy. The XFEM doesn’t require remeshing at each step and achieves the precise approximation of singularities by incorporating discontinuity behavior into the elements using the enrichment functions. The aim of using the XFEM was to obtain stress intensity factors, displacements, stress and strain around the crack tip, fracture toughness as well as strain energy release rate. Moreover, the 58s BG/PSF composite with 30% bioactive glass particles was synthesized using solvent casting method and the bending failure test was performed according to the relevant standard. Also, to demonstrate the quality of the interface between the glass particles and polysulfone, SEM investigation was performed on the fracture surface. The obtained fracture toughness was in the range of 1.4 to 1.6
, and the strain energy release rate was in the range of 1600 to 1900 J.m
-2, which was comparable to the same properties of natural human bone. Besides, the stress intensity factors and strain energy release rates were calculated by coding in MATLAB and modeling in ABAQUS, and the numerical results were validated with the analytical and experimental data and it was revealed that the numerical results were in great coordinance with the analytical and experimental results.
