Choosing the active or passive constructions for the native speakers of a language, as the name suggests, is simply a "choice" and "selection" and the speaker uses one of these two voices to express the meaning according to his situation and recognition. This conscious choice between the two structures mentioned is not a problem as long as the speaker speaks his native language. The problem begins when a person wants to speak or write in another language and for his “choice”, among the data and training that he has received in a foreign language up to this point, he looks for a reason to choose the best option among two voices and not allow errors. This article tries to answer the question: how can students for whom Russian is not their native language consciously choose a passive construction? In other words, this article is not intended to compare the Voice in Persian and Russian or to observe students’ “mistakes” in encountering this category. The article is aimed at developing a questionnaire containing the “correct” options from among the types of quasi-passive, passive and active and implementing it for 86 students of the Russian language in Iran and Russia (for whom Russian is considered a non-native language) and, based on the analysis of their answers, to reflect them "trend" in the use of passive structure. From this point of view, we try to help Russian teachers in teaching the use of the passive voice.

Despite the particular importance of the subject of soil-structure interaction, unfortunately, this issue has received little attention from engineers, and seismic codes have not given much recommendation to consider its effects. Seismic wave frequencies vary continuously, and the stiffness of springs and damping of dampers connected to structural supports also vary with the loading frequency. To simplify time-domain numerical analysis, a constant target frequency can be used to keep stiffness and damping values constant. In the substructure method proposed in this study, the optimal target frequency is the one that yields results that most closely match those of a more accurate nonlinear 3D model analyzed using a direct method. A common simplification is to ignore the foundation’s non-linear response, justified by design requirements to prevent permanent deformation and the complexity of frequency-dependent soil behavior. Though not fully precise, this approach (considering soil heterogeneity and optimal target frequency) offers a forward-looking analysis and a basis for future nonlinear studies. This study presents a three-dimensional (3D) numerical model for analyzing the seismic response of soil-foundation-structure systems embedded in granular soil (with different relative densities) considering the effects of soil heterogeneity (With varying shear modulus with depth and compatible with the practical HSsmall model). The model is capable of accounting for the effects of loading frequency along with the radiation damping of the soil system and can integrate with the widely-used substructuring method considering an optimal target frequency. After verifying the proposed model, the dynamic equilibrium equations of the substructuring system were solved in the time domain using Matlab software. The target frequency was determined using i) Case 1: the fundamental frequency of the soil (or the dominant frequency of the excitations), ii) Case 2: the fundamental frequency of the structural system, iii) Case 3: the fundamental frequency of the soil-foundation-structure system; iv) Case 4: the fundamental frequency of structure with static stiffness and damping support (Case 4); and v) the fundamental frequency of fixed base structure and modified stiffness, and the results were compared together. A comparison of the impedance (dynamic stiffness and damping) of foundations situated on homogeneous and heterogeneous soil, as well as an investigation of the structural response in both cases, is another objective of this research. The analysis results demonstrated the accuracy of the proposed model and the acceptable calculation speed for estimating the dynamic response of structures located on heterogeneous soils under frequent operational earthquakes. The results also showed that with an increase in soil relative density, the seismic behavior of structures on homogeneous and heterogeneous granular soils converges. For instance, the response of the foundation on homogeneous soil bed with relative densities of 55%, 75%, and 95% is on average 23%, 19%, and 15% lower than that of heterogeneous soil, respectively. Additionally, for determining the target frequency, the use of frequency‐independent Kelvin–Voigt models (i.e., Cases 1-5) provides acceptable responses. According to the data presented in Table 4 and Figs. 9 and 10, the following conclusions can be drawn: 1) The soil's fundamental frequency (Case 1) yielded the least precise results. 2) While Case 3 offered the most favorable response, closely matching the direct method, determining the soil-structure system's fundamental frequency through complex integration in numerical software is often impractical. 3) Employing the target frequency in Case 2 produced more satisfactory results than Case 1. 4) Cases 4 and 5 generated nearly identical frequencies. Compared to Case 2, these cases enhanced response accuracy, bringing them closer to the best response (i.e., Case 3). Therefore, for practical applications, it is recommended to utilize the fundamental frequency from either Case 4 or Case 5 instead of the soil-structure system's fundamental frequency (Case 3) to establish the optimal target frequency.

Climate change has become one of humanity's greatest challenges. Rising temperatures, weather fluctuations, and especially changes in precipitation and wind patterns have profound impacts on infrastructure and urban structures. These changes not only increase the risk of natural disasters but also affect the design and construction of buildings. Therefore, the development of innovative solutions to enhance the seismic performance and resilience of these buildings, especially in regions susceptible to climate change, is crucial. This study examines the performance of an 8-story steel structure with geometric irregularity in its plan against the effects of climate change, focusing on wind loading under three different wind speed increase scenarios including:1-low 2-moderate, and 3-severe. To mitigate the negative effects of these changes on the seismic performance of the structure, magnetorheological damper was employed. The entire floor slabs of the structure were considered rigid. The modified Bouc-Wen method was used to indicate damper behavior in dynamic equations of the structure and two control scenarios including passive control and active control were considered. NatHaz online wind simulator data base was used for modeling wind loading on structure and the Simulink environment of MATLAB was used to model the structure equipped with a magnetorheological damper under wind loading. 
The results indicated that a slight increase in wind speed led to an average increase of 35%, while a moderate increase resulted in over 60%, and a severe increase in wind speed caused more than a 100% rise in maximum displacement, drift, and base shear responses of structure. By adding magnetorheological damper to improve the negative effects of increased wind speed on the seismic performance of the structure, the damper was able to reduce the maximum displacement, drift, and base shear of the floor where it was installed by 14%, 32%, and 38% respectively in scenario (1), by 16%, 40%, and 32% respectively in scenario (2), and by 8%, 28%, and 29% respectively in scenario (3). This indicates that the damper effectively controlled the response of the floor it is installed on and was able to mitigate the negative effects of climate change. Furthermore, this damper not only positively affected the floor it was installed on but also improved the seismic response of the roof level, maintaining its effectiveness across all three climate change scenarios. Additionally, the results indicated that the damper performs better in active control mode compared to passive mode. However, the parameters related to maximum acceleration of the floor indicates a significant increase in the active control scenario, while in the passive control scenario, no significant changes were observed. The best results were achieved in the low and moderate wind speed increase scenarios. Although in the severe wind speed increase scenario, the damper maintained its effective performance. In conclusion, it can be said that the force generated by the magnetorheological damper has intelligent adjustability, which can change based on environmental conditions and loading. This feature allows structures to respond more quickly to sudden environmental changes and provides greater safety against damage caused by climatic conditions as well as enhancing the resilience of structures against adverse weather conditions.

Abstract The core concept of this article is the comparative study of the reflection of a common theme in the works of artists from different cultural backgrounds. The theme of temptation is common in the works of two artists studied here. "The temptations of Saint Anthony" by Hieronymus Bosch, the Flemish painter in the early sixteenth century and a miniature from Saadi's Bustan, "the Prophet Yusuf rejects Zuleykha" by Kamaledin Bihzad, the Persian master painter in the late 9th and early 10th century Hijra (early 16th century). The article studies the approach of each painter to the concept of "Temptation" and their perception of this phenomenon, how each one has tried to express their perception and the visual narrative they offer their audience. Through these comparisons and analysis, the authors try to examine the cultural differences as well as common cultural grounds between the Islamic and Christian cultures in one hand and on the other hand the artistic differences and similarities between the Flemish and Iranian painters' views.

We present a method to predict the flexible and rigid regions based on sequence. We use the free energy of two consequent amino acids to define a factor for distinguishing flexible regions from the rigid ones. Using statistical analysis of this free energy, we assign a normalized number between zero to one hundred which we call it flexibility number. Taking the effects of up to four neighbors of an amino acid, into account, resulted in an efficient prediction of flexible and rigid regions of a protein.

Presence of filler in the polymeric materials changes the mechanical, dynamic-mechanical, rheological properties and even the swelling behavior of rubber composite due to mechanisms such as hydrodynamics, polymer-filler and filler-filler interactions. Swelling in rubber composites directly affects the polymer chains, also can affect indirectly other structures in composites such as the filler network and reduce mechanical properties suddenly. In this study, the nitrile rubber-nanosilica composite containing different concentrations of modified nanosilica was prepared and the composite structure was studied through rheological, mechanical, dynamic-mechanical tests. Also it was found that the filler network containing over percolation threshold 13phr of filler concentration has a significant contribution to the mechanical properties of composites. To determine the swelling effect on the prepared composite structure, with different degrees of solubility were used. The mechanical properties of the samples were measured in equilibrium swelling state for each of the solvents The decrement of the mechanical properties between the dry samples and swelled ones containing 14.4, 20 and phr 6.25 silica in solvent with 15% toluene is significant. These intensive changes in mechanical properties that happen at the low degree of swelling are attributed to the removal of the filler network. Therefore, controlling the swelling of rubber parts in adjacent to the solvent, plays the fundamental role in their performance.

In this study, a planetary ball mill was used for mechanical activation of phosphate concentrate by dry milling in argon atmosphere. To investigate the structural changes of fluorapatite, amorphization degree, crystallite size, micro-strain, particles size, specific surface area changes and new phase formation were investigated. The crystallite size and micro-strain were estimated using Williamson-Hall method. To investigate the influence of effective parameters on mechanical activation, the ball to powder ratio of 20:1 and 40:1 with two types of balls of 9.4 and 20 mm and speeds of 200 and 500 rpm was used. The results showed that agglomeration of particles occur at higher intensities of mechanical activation, but no phase change occurs during high intensity ball milling. The most variations in crystallite size, micro-strain, surface area, amorphization degree and XRD line broadening were for samples that were activated by smaller balls for longer time. The results of the Williamson-Hall plots showed that the maximum effect of mechanical activation on phosphate concentrate was in the first 20 minutes with small balls and the crystallite size, micro-strain and amorphization degree was changed from 225 nm, 0.09% and 0% for initial sample to 64.29 nm, 0.9% and 80.081% for mechanically activated sample, respectively. Also the results showed that changes in cell parameter at c direction had larger effect on unit cell volume. The maximum unit cell volume variations were corresponding to mechanically activated sample with 9.4 mm balls that changed from 525.4 (A³) for initial sample to 528 (A³) for activated one after 90 min.

"Structure" should be regarded as the most basic discussion of translation in the Contrastive Linguistics. The linguistic structures, studied in the five sections of syntactics, morphology, lexico-semantis, phonetics and rhetoric, play the crucial role in cross-linguistic analyses. The first two structures, namely syntactical and morphological ones, are also called as grammatical, on which I tried to concentrate my effort to analyze them in this essay on the ground of the Holy Koran translation process.

Ph. D.student in Persian Language and Literature Of Tehran University   Structuralists consider literature to have a structure similar to language and try to compile special syntactic rules for it. In fiction, Structuralism mainly studies narration.Structuralist narratologists try to compile a single coherent narrative structure for the different domains of fiction. In this article, we have tried to analyze one of the most famous Persian novels,Shazdeh Ehtejab by Houshang Golshiri ,within the framework of the structuralist viewpoints of Genette, Greimas, Bramond, Todorov and Barthes. To do that, we have studied the structure of Shazdeh Ehtejab in three levels: in the first level which we call "narrator and point of view in Shazdeh Ehtejab" we study the point of view,method of narration and the narrator/ narrators who narrate Shazdeh Ehtejab.In the second level we study the narrative structure of Shazde Ehtejab and in the third level we structurally analyze Shazdeh Ehtejab

In human-made materials, aerogels have the least thermal conduction coefficient. The least thermal conduction, which aerogels can have, is equivalent to air conduction, about 0.021W/mK. In some applications, lowest conductions is to be needed. In this study, novolac aerogles are used as spacer, for designing and making multilayer super insulators with aluminum foil reflective layers. The performance of these insulators, are extremely depends on density, porosity and the size of pores in aerogel and number of layers in the overall thickness of insulator. In this study, for decreasing effective thermal conduction of multilayer insulations, tow parameters of density of aerogel and ratio of number of layers to thickness of insulator (layer density), are examined in 25 ˚C to 200 ˚C boundary conditions. First, by assessment of aerogel novolac density effect on thermal conduction, aerogel with density of 0.076 g/cm3 was chosen as the best spacer. In the next part, ratio of 25 layer per centimeter of thickness was chosen as the best layer density. Finally, by making multilayer super insulators, based on this results, an insulator with 5×10-4W/mK effective thermal conductivity was obtaind without evacuation of spacer.
