Abstract

Aims: Determining the effective factors in the use of e-learning among students can be useful in providing appropriate and practical solutions to increase the use of e-learning. Therefore, this study aimed to determine the factors related to the behavior of using e-learning among medical university students using the technology acceptance model (TAM) as a conceptual framework.
Instrument & Methods: This cross-sectional study was conducted among 425 students of Hamadan University of Medical Sciences who were selected by stratified random sampling. The data collection tools included a questionnaire, including demographic data and TAM constructs. The data were analyzed in SPSS 23 software using one-way analysis of variance, independent t-test, Pearson correlation coefficient, and linear regression analysis.
Findings: The age range of participants was between 18 and 54 years with an average age of 24.2±3.96 years. The history of participating in e-learning classes was significantly related to all the constructs of the TAM (p<0.05). Also, undergraduate and graduate students had a significantly more positive attitude, higher perceived usefulness, and more usage intention and behavior concerning e-learning than professional doctorate students (p<0.05). Attitude (β=0.394), perceived usefulness (β=0.313), and external variables (β=0.196) were respectively the strongest predictors of intention to use e-learning (p<0.05). The intention of e-learning usage directly and significantly predicted the behavior of using it (β=0.483, p<0.05).
Conclusion: The TAM constructs predict the behavior of using e-learning among students.

Abstract

 To consider significant variation of dialects of Gilaki Language and different approaches on the classification of clitics and different usage of this element in the Iranian dialects and languages, writer purposes to determine variation of clitics in Gilaki language, various features of clitics and their position in this language. There are two questions here: 1-how is typological verity of clitic and its feature in Gilaki language? 2- where is the position of clitic in the sentences of this language? it seems that there is same varity of clitic in three dialect divisions of Gilaki and clitic occupy second position into the sentences of this language. linguistic data of Gilaki has been investigated on the basis of a questionnaire of Max Plank written on typological investigations of clitics on which It has been analyzed in 5 separable parts including general features of the language, categories, specific features, place of clitics in the phrases and its movement. Collected data from three branches including west, east and Galeshi has been analyzed on basis of descriptive- analytical- comparative method. The results will express that there is sameness of clitics among three mentioned branches of Gilaki. Generally we can observe pronoun pre-clitics connected to objective symbol, Objective symbol post-clitics /ǝ/, emphasis clitics and post- clitics of the symbol of conjunction /O/ in Gilaki language.There aren’t Post-clitics of personal pronouns connected to nouns, verbs, adverb and adjectives in this language. It isn't possible to move clitics to the prior position. Indeed considering the investigations, Wackernagel’s law about second position is verifiable for Gilaki language.

1. Introduction
Gilaki is one of Iranian northwest languages and a member of Caspian seaboard languages. It has many differences with Persian and many similarities to Medes, Parthian and Avestan languages (Stilo, 2001). In this article, we will present a typological analysis on clitics in three geographical divisions of Gilaki language. We intend to utilize some of typological devices from Max Planck linguistics institute to determine the varieties of clitics, its feature and the position of this element in Gilaki language. Generally, distribution and operation of clitics as a significant concept of morpho-phonemic studies are investigated in this project and our main theoretical approach is linguistic typology.
There are two questions here:
1-how about typological variety of clitics and its features in Gilaki language?
 2- where is the position of clitics in the sentences of this language?
 
2. Literature
2.1. This is level 2
Zwicky (1977) has analyzed the clitics and Sportich (1992) has focused on the structure of clitics. Condoravdi and Kiparsky (2004) in their article entitled “ Clitics and Clause structure” have investigated the clitics variety in the middle and contemporary Greek language. They believe that some of clitics in some of dialects of this language find their roots in a projection of inflectional clause and they belong to a verbal head in other dialects. Anderson (2005) expresses that pronouns are so common to be as clitics and pronominal clitics have their specific features which some of them are relevant to being clitics and some of them are not.
Moreover, there are many Iranian researches on clitics. Shaghaghi (2006) has presented a definition of clitics and its features. Rasekh Mahand (2010) believes that all of pronominl clitics in the languages all around the world are located in two positions: 1- Wackernagel’s position. It means after the first words of sentences or constitutions. 2-  before or after the verbs of sentences or constitutions located before the verbs. Sarahi and Alinejad (2014) have investigated clitics in Persian language typologically. Alinejad and Mohammadi (2015) have analyzed clitics in Surani dialects of Kurdish language and its collaboration with prepositions. Mazinani, alizade and Sharifi (2017) have shown that evolution of clitics in Persian language presents a good explanation of inconsistence of this language with Dryer’s vigesimal standards and Greenberg’s No. 20 universal. SabzAlipour and Vaezi (2019) have discovered the function of clitics in agreement system instead of verbal pronoun and lack of doubling clitics in Dorvi dialect of Tati language.
 
3. Methodology
 Throughout the current research , linguistic data of Gilaki has been gathered via field research on native speakers of some villages and towns of Guilan province. Then the data has been investigated on the basis of a questionnaire of Max Plank written on typological investigations of clitics on which it has been analyzed in 5 separable parts including general features of the language, categories, specific features, place of clitics in the phrases and its movement. Collected data from three branches including west, east and Galeshi has been analyzed on basis of descriptive- analytical- comparative method.
 
4.Results
The results will express that there is sameness of clitics among three mentioned branches of Gilaki. Generally we can observe pronominal pre-clitics connected to objective symbol, Objective symbol post-clitics /ǝ/, emphasis clitics and post- clitics of the symbol of conjunction /O/ in Gilaki language. There aren’t Post-clitics of personal pronouns connected to nouns, verbs, adverb and adjectives in this language. It isn't possible to move clitics to the prior position. Indeed considering the investigations, Wackernagel’s law about second position is verifiable for Gilaki language.

Abstract

Thin-walled structures are widely used in different engineering applications. Bridge and building plate girders, box columns and girders, frame bracing systems, liquid and gas containment structures, shelters, offshore structures, ship structures, slabs, hot-rolled W-shape steel profiles, steel plate shear wall systems and many other naval and aeronautical structures are examples of engineering elements that according to their applications use plate of various thicknesses. The knowledge of the actual behavior of plates in such structures can be, of course, helpful in understanding the overall behavior of the structures. In general, plates in thin-walled structures may be under various types of loading, such as shear loading. Material yielding and geometrical buckling of plates are two independent phenomena which may well interact with each other in shear panels. Depending on the material properties, slenderness and aspect ratios, and boundary conditions of perfectly flat plates, yielding may occur before, after or at the same time as buckling. Buckling in slender plates is a local and sudden phenomenon followed by large out-of-plane displacements and loss of stiffness. Slender plates are capable of carrying considerable post-buckling additional loads due to stresses in the inclined tension fields. On the other hand, a plate with low slenderness ratio yields before buckles and thus, no post-buckling capacity is expected. In between, in plates with moderate slenderness ratios, material yielding and geometrical nonlinearity happen almost at the same time. In the present paper, the behavior characteristics of shear panels with simple or clamed boundary conditions and three different materials (carbon steel, stainless steel and aluminum) are studied for various plate slenderness ratios, using finite element method. Results of nonlinear static analyses of different shear panels show that slender plates, depending on the slenderness ratio, carry a relatively small shear load in the elastic stage until the occurrence of shear buckling, but their additional capacity in the post-buckling stage prior to yielding are significantly large. They reach their ultimate shear capacity slightly after yielding. That is, their post-yield capacity is not significant. Note that the ultimate shear strength of slender plates is considerably lower than their nominal shear yield strength. In plates with intermediate slenderness ratios, material yielding and buckling occur concurrently. They carry a relatively large shear load in the elastic stage before yielding/buckling. They have also some post-buckling/post-yield reserves before failure. The ultimate shear strength of moderate plates is somewhat lower than their nominal shear yield strength. In stocky plates, yielding precedes buckling. The shear capacity in the elastic stage before yielding is thus significant. The plates have some post-yield capacity and the ultimate load is coincident with the occurrence of plastic buckling (if happens). The ultimate shear strength of stocky plates is almost equal to their nominal shear yield strength. Moreover, results of quasi-static cyclic analyses of different shear panels show that the energy absorption capability, as expected, is very sensitive to the slenderness ratio of panels and with the decrease of the slenderness ratio (increase of thickness), the absorbed energy by the panels is substantially increased. For a specific slenderness ratio, steel shear panels exhibit higher energy absorption than panels with aluminum materials (although aluminum material has higher yield strength than that of carbon steel and stainless steel materials, here). This, of course, highlights the important role of the modulus of elasticity in the energy dissipation capability of shear panels. However, the material yield strength and panel boundary conditions do not seem to have important role in the amount of energy dissipated by the panels, compared to the material modulus of elasticity.

Abstract

study, 13 factors were finally extracted as key variables and drivers in the optimal performance of the cooperatives. All 13 factors were repeated in both direct and indirect methods.

Conclusion
The results show that the drivers of housing cooperatives' performance including "coherent measures to get the housing market out of recession; involvement of housing investment institutions, mass builders, and cooperatives in housing production; and satisfaction with housing efficiency" are marginalized. This trend shows that these indicators do not tend to improve, and with the current trend, the situation in the organization will continue to be unfavorable. As a result, the necessary condition for improving performance of cooperatives in the physical and spatial changes of Tabriz city based on decentralized planning and meeting the needs of all citizens in the future, is the promotion of the above indicators.

Abstract

MicroRNAs (miRNAs) are typically small, endogenous, non-coding RNAs molecules that regulate gene expression at post-transcriptional level by mRNA degradation or translational repression. They are composed of 18-26 nucleotides and are conserved during evolution for the development of new miRNAs in a variety of plants. Sugarcane (Saccharum officinarum) is generally a valuable food and forage crop grown all over the world. Until now, different sugarcane miRNAs have been characterized for plant development and stress responses. In this research, 50 unique conserved sugarcane miRNAs from 44 different miRNA families have been predicted using a variety of genomics-based tools. The predicted sugarcane miRNAs were validated using a set of 15 randomly chosen primers and RT-PCR. Stem loop secondary structures are created using MFOLD tool. The psRNA-Target algorithm identified 7,976 various protein targets of sof-miRNAs including 55 specific GO terms. They have significant targets in biological, cellular, and molecular functions. Moreover, the sof-miR5205a regulates sulfur compound biosynthetic process and 9653a directs ubiquitin-dependent protein catabolic process. Consequently, the RNA binding and thylakoid membrane are controlled by sof-miR9657b and 2091, respectively. As a result, the outcomes of the novel sugarcane miRNAs target a variety of substantial genes that aid in controlling the environment for sugarcane to produce a higher quality crop.
