A model is provided for crack problem in a functionally graded semi-infinite plate under an anti-plane load. The characteristic of MATERIAL behavior is assumed to change in a LINEAR manner along the plate length. Also the embedded crack is placed in the direction of the MATERIAL change. The problem is solved using two separate techniques. Primary, by applying Laplace and Fourier transformation, the governing equation for the crack problem is converted to the solution of a singular integral equation system. Then, finite element technique is employed to analyze this problem by considering quadrilateral eight nodded singular element near the crack tips. The effects of MATERIAL non-homogeneity and crack length on the stress intensity factor are studied and the results of two methods are judged against each other.

This research aims at characterizing SnS/SnO MATERIAL for photovoltaic applications where the molar concentration of tin (Sn) varied as the parameters for characterization in the synthesis's process from 0.1-0.4 mol via the successive ionic layer adsorption reaction (SILAR) approach. A face-centered cubic structure with orientations along the 200 plane corresponds to the considerable peak at 2theta values of 31.82o. The lattice constant rises as the 2-theta angle rise from 20o -70o, causing the MATERIAL's diffraction peak to become less intense. Crystallites made up of different sizes were found with the film deposited with 0.1 mol of tin, comprising unevenly shaped rods and loosely packed particles, whereas at 0.2 mol, the crystallite size is more sizable than the MATERIALs deposited at 0.3 mol to 0.4 mol and gets smaller as the molarity level rises. The thickness of the MATERIAL rose from 109.12 to 112.21 nm, which caused the resistivity of the deposited MATERIAL to decrease from 9.562 × 109 -7.312 × 109. The electrical conductivities of the deposited SnS/SnO MATERIAL increased proportionally to the thickness of the MATERIAL with values between (1.045-1.367) x 10-10.

Sluggish Cognitive Tempo is used to describe a particular type of attention deficit, concentration, and slowness in information processing. The aim of this study was to investigate the psychometric PROPERTIES of the Sluggish Cognitive Tempo Scale (SCTS) of the parent form among Iranian children. The present study is a descriptive study. A sample of 1700 people was selected from the provinces of Tehran, East Azerbaijan, West Azerbaijan, Kurdistan, Fars and Khorasan using cluster sampling method. 122 subjects were excluded from statistical analysis due to incomplete answers to the questionnaires and thus the final sample was reduced to 1578 parents. The confirmatory factor analysis method and internal consistency were used to compute the Sluggish Cognitive Tempo Scale factorial validity and reliability, respectively. Also, in order to examine the construct validity of the Sluggish Cognitive Tempo Scale, we computed correlations between different dimensions of Sluggish Cognitive Tempo Scale with Attention Deficit Subscale of Mental Health Assessment Questionnaire for Children and Adolescents. The results of statistical results showed that this scale has structural validity, criterion and convergence in Iranian society. The results indicate that the scale is three factors and also the validity of the scale using Cronbach's alpha method and retest test after Approved two weeks. According to the findings of the present study, the parent form of the Sluggish Cognitive Tempo Scale (SCTS) has a good validity and reliability and it can be used in research related to slow cognitive multiplication in Iranian society.

In the present paper, we study some PROPERTIES of fuzzy norm of LINEAR operators. At first the bounded inverse theorem on fuzzy normed LINEAR spaces is investigated. Then, we prove Hahn Banach theorem, uniform boundedness theorem and closed graph theorem on fuzzy normed LINEAR spaces. Finally the set of all compact operators on these spaces is studied.

First, polyimide (PI)-epoxy resin (EP) polymer matrix was prepared from 3, 3′-diethyl-4, 4′-diamino diphenyl methane (DEDADPM), benzophenone tetracarboxylic acid dianhydride (BTDA) and epoxy resin (E-51), through thermal imide process. Then, the nanometer alumina (Al2O3) modified by the coupling agent, (3-aminopropyl)triethoxysilane (KH550), was doped into the PI-EP polymer matrix, using an in situ sol-gel method to prepare a series of KH550-Al2O3/PI-EP nanocomposite MATERIALs based on different KH550-Al2O3 contents. Fourier transform infrared spectroscopy (FTIR) indicated that in the presence of chemical reaction between poly (amic acid) and epoxy resin, an imide ring was formed, the thermal imidization reaction of the MATERIALs was completed and the KH550-Al2O3 had doped into the PI–EP polymer matrix. The heat-resistance, dielectric specification and mechanical PROPERTIES of KH550-Al2O3/PI-EP nanocomposite MATERIALs were evaluated. The results showed that the decomposition temperatures were ranged between 438 and 450oC, dielectric constant and dielectric loss were in the range of 3.32-3.71 and 1.5 × 10-3-2.5 × 10-2, respectively, and they all increased with the increase of KH550-Al2O3 content (0-10 wt%), but the shear strength first increased and then decreased, attained its maximum value of 10.64 MPa at 8 wt%, which was about 119 % higher than that of undoped MATERIAL. The adhesive forces of nanocomposite MATERIALs were all at higher level (one or two levels). Thus, the overall performance of KH550-Al2O3/PI-EP nanocomposites was the best when the doping amount of KH550-Al2O3 was 8 wt%. The PROPERTIES such as high heat-resistance, dielectric PROPERTIES and ready attachment of impregnating varnish to steel plate with very high strength fully met the necessary requirement.

In this work vibrational-damping PROPERTIES of a viscoelastic MATERIAL of a Russian vibration absorber coating named сkjiG-27м is investigated. For this purpose ASTM E756-05 standard is employed and corresponding experimental tests are performed step by step. This standard test method is useful to obtain vibrational-damping PROPERTIES of MATERIALs and can makes it possible to apply viscoelastic MATERIAL in passive vibration control applications in a beneficial manner. Since the investigated vibration absorber coating is of type of constrained layer damping or CLD, a sandwich specimen is fabricated according to the standard instructions. Then by performing experimental modal testing on the sandwich specimen and base steel beams as cantilever beams, the desired outputs including variations in loss factor and shear modulus of the viscoelastic MATERIAL versus frequency are obtained. Also the accuracy of conducted tests are checked out using the standard criteria which the outcomes confirm the validity of tests and results.

The use of dental MATERIALs in the human mouth is not possible except by relying on physiological, biological, pathological studies and the study of physical, mechanical, and chemical PROPERTIES. Pulp capping is a treatment to deal with cases of reversible pulpitis that initiates the formation of reparative dentin so that vitality and tissue function can be maintained. The use of mineral trioxide aggregate (MTA) as a pulp capping MATERIAL has shown promising results in clinical trials. The success of pulp capping treatment can be seen from reparative dentin formation through histological examination. The aim is to determine the potential use of MTA as a pulp capping MATERIAL against reparative dentin formation. Secondary data from several search engines such as ProQuest, Taylor and Francis, PubMed, and Wiley appropriate with keywords were obtained through 334 journals. Journals were filtered and identified by title, abstract, and keywords with a total of 28 journals; then, they were re-filtered by considering the complete contents yielding five journals. All the research journals reviewed in this literature revealed that pulp capping with MTA on permanent human teeth could form reparative dentin. One research journal only investigated the absence of reparative dentin; two other research journals used the location of the formation of reparative dentin against medicament.In contrast, the other two journals utilized the thickness of reparative dentin as the assessment criteria. MTA as pulp capping MATERIAL for reversible pulpitis treatment can form reparative dentin that could be seen from the histological examination. The quality of reparative dentin can be evaluated based on the thickness of the reparative dentin and the location of the reparative dentin formation against pulp capping MATERIAL.

One of the factors that can be the link between our intentions and actions and their external consequences is human agency, which indicates the conscious design and intentional execution of actions by the individual in order to influence future events.Objective and Method: This research with a developmental approach of psychometric method and method 1, examines the psychometric indices of the Human Factor Characteristics Scale using the classical theory of test score measurement and the graduated question-answer theory. The purpose of this study, which included high school students in Tehran, was selected by cluster sampling of 500 people as a sample size and statistical analysis was performed on 481 data. To collect the data, the ion Human Agent Characteristics Scale (2011) was used and the research questions were evaluated using IRTPRO and SPSS software.Results:The assumption of local independence based on Pearson x2 index was established by applying Simjima's calibrated question-answer theory and the assumption of being one-dimensional based on the analysis of multidimensional question-answer theory. Diagnosis parameters with question-answer approach and classical approach Test score Both item 25 approach had the lowest and item 2 had the highest diagnosis parameter. The answer thresholds for all the questions were so far apart that no option was covered by the other option, and the options were independently selected by individuals at intervals of theta. The total scale was calculated with Cronbach's alpha of 0.945, intentionality of 0.894, foresight of 0.780, self-reactivity of 0.871 and rethinking of 0.762. Also, the role of each item in internal consistency was investigated by the loop method, which all questions had a favorable role in internal consistency of this scale. The value of the validity coefficient obtained from the question-answer theory was obtained by marginal method for intentionality 0.92, forethought 0.85, self-reaction 0.91, rethinking 0.83..
