This study investigated the relationship between coaches' leadership style and satisfying the basic psychological needs of the premier-league male Kabaddi players. The statistical population includes all premier-league male kabeddi players' (144 male). Two questionnaires on coaches' leadership styles (LSS) and satisfying basic psychological needs were used to collect data. Descriptive statistics were used to analyze and classify the data. Multi-variable regression was used to estimate the value and function of the independent variable on the dependent variable and complementary analysis. Structural equations (SEM) were used for modeling the parameter and trial analysis using LISREL software. Results show that coaches' leadership styles directly affect satisfying basic psychological needs. In conclusion, we suggest that coaches provide players' needs through positive interpersonal relationships, involving them in decision-making and motivating them to achieve desirable performance.

The effect of various host plants including chickpea (varieties Arman, Hashem, Azad and Binivich), common bean (variety Khomein), white kidney bean (variety Dehghan), red kidney bean (variety Goli), cowpea (variety Mashhad), and tomato (variety Meshkin) on the reproductive performance and growth indices of the cotton bollworm, Helicoverpa armigera (Hübner) was determined under laboratory conditions (25 ± 1°C, 65 ± 5% RH and a 16:8 h light:dark photoperiod). The highest rate of gross fecundity, gross fertility, net fecundity, net fertility, mean daily eggs and mean daily fertile eggs were observed on chickpea Arman (2947.8 ± 7.8, 2933.0 ± 7.8, 2404.2 ± 7.1, 2392.2 ± 7.1, 170.9 ± 0.4, and 170.1 ± 0.4 eggs female^-1, respectively), whereas the lowest values of these parameters were on tomato Meshkin (847.5 ± 9.2, 673.8 ± 7.3, 225.5 ± 2.6, 179.3 ± 2.1, 67.9 ± 0.7 and 54.3 ± 0.5 eggs female^-1, respectively). The development index of overall immature stages varied from 1.10 to 1.57, with the minimum on tomato Meshkin and the maximum on chickpea Arman. Also, the fitness and standardized insect-growth indices were highest (0.349 ± 0.009 and 0.058 ± 0.001 gr day^-1) and lowest (0.052 ± 0.001 and 0.013 ± 0.000 gr day^-1) on chickpea Arman and tomato Meshkin, respectively. The Weibull model sufficiently described the shape of the survivorship curve of adult H. armigera from life-table data. A significant fit was obtained with the Weibull model for H. armigera in all experimental host plants. The results of reproductive performance, growth indices and the cluster analysis showed that tomato Meshkin was partially resistant to H. armigera.

An analysis of the state of Iran's water resources shows that hydro-political challenges have shifted from the national scale to the sub-national scale (at the catchment level) and the conflict of interests of users has led to a contradiction in the approach of agents, especially in times of drought. Meanwhile, Karkheh catchment in Khuzestan feeds by Kashkan river in Lorestan province. On the other hand, climate change and Kashkan floods have often been associated with losses. The basic agricultural livelihood of Delfan city and the prevention of floods have made the construction of Gaushmar dam on Kashkan inevitable. The construction of this dam has reduced the volume of water entering the downstream cities of the dam and the Karkheh catchment in Khuzestan, especially during dry seasons. The construction of this dam has led to the conflict of interests of the actors and the emergence of hydro-political challenges on a subsidence scale. The present article is applied and the methodology of the text is explanatory-analytic. The data and information required for the research were collected by library and field methods (interview). The result of the research showed that with the construction of Gaushmar Dam, hydro-political relations within the province (Lorestan) and extra-provincial relations between Khuzestan and Lorestan provinces have been brought hydro-political tension. The adaptation of these conflict of interests eventually led to a reduction in the height of the dam and the volume of water stored behind the dam due to the authorities’ policies.

Task-based language teaching (TBLT) characterized by involving language learners in meaning-focused activities with some focus-on-form has enjoyed increasing popularity in the past two decades. Meanwhile, ample theoretical and empirical evidence has been presented to account for different task design features that influence language learning and learners’ performance. However, selecting and sequencing suitable tasks as well as recognizing appropriate task combinations that can provide a good opportunity for learning are still topical issues in SLA research (Robinson, 2011; Skehan, 2014).
Considering this interest, this study set out to examine whether changes in the cognitive demands of tasks and their implementation condition (operationalized by individual and collaborative writing) would lead to differential improvement in language learners’ writing performance. The study also explored the relationship between an under-researched learner factor (self-regulation) and EFL learners’ written performance in individual and collaborative tasks varying in terms of cognitive complexity. The novelty of the present study lies primarily in its considering the combined effect of task complexity and task condition on writing—which is a somewhat neglected mode in research on TBLT—of EFL learners.
Although different models and criteria have been proposed to account for task complexity, psycholinguistic rationales have drawn more support recently. Skehan’s (1998, 2009) trade-off hypothesis and Robinson’s (2001, 2003, 2009) cognition hypothesis are two influential models in vogue toady. Different views on attentional capacity of human beings have led Skehan and Robinson to have almost contradicting predictions on learners’ performance in tasks with different levels of cognitive complexity. Robinson (2001, 2003), assuming multiple-resource model of attention, holds the view that performing some complex tasks (e.g., those made complex by the number of elements) pushes learners to make efficient use of their attentional resources and produce more accurate and complex output. Contrarily, Skehan (1998), acknowledging the limited attentional capacity of learners, claims that simultaneous increase in accuracy and syntactic complexity of linguistic output is not feasible just due to the manipulation of task complexity. He claims that learners carrying out cognitively demanding tasks have to prioritize one (accuracy or complexity) at the expense of the other.
Two research questions were formulated for the present study: (a) Do task complexity, task condition, and their interaction affect the accuracy, syntactic complexity, and fluency (CAF) of language learners’ written performance? (b) Is there any relationship between self-regulation of language learners and their performance in individual and collaborative writing tasks varying in terms of cognitive complexity? To answer these questions, 122 EFL learners whose homogeneity was ensured by Nelson English Language Proficiency Test were recruited. They were randomly assigned into four groups. The participants in four groups carried out the tasks which were different in terms of cognitive demands (simple/complex) and their implementation conditions (individual/collaborative). Task complexity was manipulated by the number of elements that participants had to consider while performing the writing task.
The collected data were analyzed by MANOVA and Pearson correlation after checking for the assumptions underlying these statistical analyses. Findings revealed that task condition had a significant effect on the writing accuracy of language learners but manipulation of task complexity did not affect three writing dimensions, i.e., syntactic complexity, accuracy, and fluency (CAF) significantly. These findings lent partial support to Skehan’s (2009) trade-off approach toward task design and also Vygotsky’s (1978) social constructivism. Moreover, self-regulation of learners who performed the complex writing task in isolation showed a positive significant correlation with the accuracy of their writing. Robinson (2011) has made a similar prediction regarding the role of individual differences in learners’ performance in complex tasks. The findings add support to the view that selecting appropriate levels of task complexity and suitable task implementation conditions enhance different dimensions of the written performance of language learners. The study calls for more prominent place for task condition and individual differences of learners in the frameworks and models put forward for task designing and sequencing.

The word " Qaswara " ((قَسْوَرَه  in the verse "Farrat men Qaswara "(فَرَّتْ مِنْ قَسْوَرَهٍ ) is one of the words that the translators, especially the Persian translators, have not translated in the same way. Unlike the Persian translations, the Latin translators have translated the word in almost the same way, but it is often accompanied by a question mark and sometimes an exclamation, which indicates the translator's doubt about the meaning of the word. In addition to the translators, commentators have also expressed different views on the meaning of this word, so that more than seven meanings for this word have been mentioned in the interpretations. There are many narrations in Shia and Sunni commentary sources regarding the meaning of Qaswara. Therefore, the commentators have chosen a separate interpretation for themselves based on the hadiths. This research has been done with a historical and linguistic approach and with a descriptive-analytical method, with the aim of finding the causes and origins of the difference in the meanings of this word in the process of time and presenting a meaning that is close to correct. Examining the sources of the word and the historical course of the interpretations and the analysis of the traditions carrying the meanings of this word show that both the lexicographers and the commentators do not have a definite opinion on the meaning of the word and over time some meanings prevailed over others and were gradually established and later it crystallized in the translations. The study of the genealogy of the word in the Semitic and Syriac languages shows that this word in this language means a weak donkey, which can be used in the semantics of "Qaswara".

The term "Ḥusbānan" in the verse "... wa Yursila ʻalayhā Ḥusbānan min al-Samāʼ…" is one of the words that have different interpretations in Persian and Latin interpretations and translations. Meanings such as punishment, fire, lightning, hail, cold, wind, calamity, etc., have been mentioned for it in interpretations and translations. The present study, using a historical-analytical method, aims to find the reasons for the difference in the meaning of "Ḥusbānan" and employs a modern semantic approach (associative relationships) to present the correct meaning. Examination of lexical sources and interpretations indicates that some differences are based on linguistic foundations and some on narrative ones. The available hadiths have issues in terms of authenticity and convey multiple meanings, making their prioritization challenging. Additionally, lexical sources have not been able to prevent differing viewpoints; the historical trend of interpretations shows that in the early centuries, the meaning and application of "Ḥusbān" were limited, but from the sixth century onwards, they expanded. In this study, by using substitutional relationships, an effort has been made to present a more precise meaning and application.

This study was conducted to investigate the effects of the medicinal plant yarrow (Achillea millefolium L.), a probiotic (Primalac) and an antibiotic (virginiamycin) on gastrointestinal tract (GIT) characteristics, microbial populations, immune response, serum lipids and growth performance of broiler chickens. A total of 250 one-day old male broilers (Ross 308) were randomly allocated to 5 treatments, 5 replicates with 10 birds in each in a completely randomized design. Experimental treatments included the control, yarrow powder at two different concentrations (1.5 and 3% of diet), Primalac (0.1% of diet) and virginiamycin (15 ppm). The highest feed conversion ratio (FCR) was observed in the control while the lowest FCR was seen in the virginiamycin group at 42 days of age (P< 0.05). Moreover, the highest body weight gain (BWG) was observed in the virginiamycin group while the lowest value was related to the control animals (P< 0.05). Carcass yields were not different between treatments (P> 0.05). Relative weights of breast and thigh were similar among all treatments (P> 0.05). Relative weights of bursa Fabricius, spleen and primary immune response (total titer, IgG and IgM) against sheep red blood cells (SRBC (were not affected by treatments. The serum cholesterol, triglyceride as well as high and low density lipoprotein (LDL and HDL) levels were different among treatments (P< 0.05). The lowest concentrations of the mentioned parameters were obtained in the group supplemented with 3% of yarrow (P< 0.05). The highest and lowest antibody titers (secondary immune response) against SRBC were observed by the yarrow (3%) and antibiotic supplementations, respectively (P< 0.05). The highest lactic acid bacteria (LAB) counts were detected in the crop, ileum and cecum of the Primalac group (P< 0.05). Inclusion of virginiamycin and yarrow (3%) caused a significant decrease in coliforms and total aerobic bacteria counts in crop, ileum and cecum (P< 0.05). The results of this study showed that the administration of yarrow (3%) can reduce the levels of serum lipids and boost the immune response in broilers. Moreover, it led to reduced pathogenic bacteria population in the GIT which could help to improve intestinal health and well being of poultry. It is proposed that yarrow can be used as an antibiotic alternative.

In this paper, elastic-plastic deformation of a rotating hollow FGM cylinder is analytically studied based on small strain theory and for plane-strain state. Variation of elasticity modulus, density and yield stress are assumed to obey power-law functions of radial coordinate. Material was assumed to obey Tresca yield criterion and its associated flow rule. To evaluate and validate the presented analysis, numerical results were compared with previously published results for homogeneous and also FGM cylinder with constant density and yield stress, as two special cases. Then the effect of density and yield stress variation, which was not considered in the previous researches, was investigated on the elastic-plastic deformation of the FGM rotating cylinder. The results show that when the variation of density and yield stress is ignored, considerable differences may arise not only in the magnitude of computed radial displacement and stress and strain components, but also in predicting the pattern of yield initiation and also plastic zone development.

Identification of elastic constants of three-dimensional anisotropic materials is much more complicated than the corresponding one in two-dimensional materials. This is because of the increased number of the elastic constants in three-dimensional materials. In this paper, an inverse method for determination of elastic constants of three-dimensional orthotropic, monoclinic and anisotropic materials using elastostatic measurements is presented. Strain measurements at some sampling points obtained from several elastostatic experiments are considered as the elastic response of the material. The solution is based on minimization of the difference between measured strains and the corresponding calculated ones at sampling points. The finite element method is used for sensitivity analysis, while the Tikhonov regularization method is used for stablizing the solution. Designing a single elastostatic experiment in which all of the material parameters affect the response distinctively is very difficult and seems impossible. By using the data obtained from a few different experiments, we are able to collect enough information to reach a stable and accurate solution. In the present research, 9 constants of orthotropic materials, 13 constants of monoclinic materials and 21 constants of anisotropic materials have been successfully identified. Effects of different parameters on accuracy and efficiency of the proposed method are studied by presenting several numerical examples.

This article investigates energy absorption capacity and plastic deformation trend of lateral flattening of an aluminum profile with H-shaped cross section under the quasi-static lateral loading by experimental, numerical and theoretical methods. Samples were prepared with different lengths and three different filling conditions including empty, core-filled and perfectly-filled by polyurethane foam. In addition, samples with the same geometry and filling conditions were laterally compressed with loading angles of 0 and 90 degree. Effect of some parameters such as length, three different filling conditions and loading angle were experimentally investigated on lateral force and specific absorbed energy (SAE). The results show that SAE is independent of samples length. At the loading angle of 90 degree, presence of the filler causes increment of SAE by the structure. Using the perfectly-filled profile under the loading angle of 90 degree is the most optimum condition. Based on two different energy absorption mechanisms, a theoretical equation was derived to estimate total absorbed energy (TAE) by empty sample with loading angle of zero; and predicted results were compared with the experimental samples. Due to present limitations in preparing the samples with different geometrical dimensions, nonlinear ABAQUS software was employed. Some samples with different wall thicknesses were modeled and influence of thickness was investigated on TAE. TAE is directly correlated to the second power of wall thickness; and this relationship can be clearly understood from the theoretical equation and numerical results. High correlation of experimental, numerical and theoretical results indicates precision and accuracy of the performed research.

The method of fundamental solutions is a boundary-type mesh-free method, which is very suitable for problems with unknown or moving boundaries. In this paper, the method of fundamental solutions is employed for shape optimization in torsion problems. The objective of this work has been to find optimum corners radii of hollow cross-sections under torsion for minimizing the maximum stress. First, it is shown that for the optimum value of the corner radius, the maximum shearing stress on the outer boundary should be equal to the shearing stress at internal corner. Considering this fact, a suitable objective function is defined and then it is minimized using the Levenberg-Marquardt method, which is a gradient-based optimization method. The configuration of collocation and source points has a very important effect on the accuracy of the solution in the method of fundamental solutions. Here, a two-constraint method is used for proper configuration of source and collocation points. To verify the accuracy of the developed code for torsion analysis of hollow members using the method of fundamental solutions, an example with a hollow elliptical domain is presented. The obtained numerical results are compared with the results of exact solution, which show a very good agreement. The optimum values of corners radii for members with square, rectangle and trapezoid cross-sections and different thicknesses have been successfully found. Then, using the obtained results, a formula for the optimum value of the radius of internal corners of hollow rectangle cross sections is constructed.

The aim of this study was to investigate the effect of bacteria strain (Lactobacillus rhamnosus and Lactobacillus plantarum) and encapsulation system (multilayer and simple emulsion) on physicochemical, stability and viability characteristics of bacteria. Particle size of LR-ME (Lactobacillus rhamnosus embedded in multilayer emulsion), LR-E (Lactobacillus rhamnosus embedded in simple emulsion), LP-ME (Lactobacillus plantarum embedded in multilayer emulsion) and LP-E (Lactobacillus plantarum embedded in simple emulsion) was measured as 10.63, 3.53, 10.47 and 4.19 μm, respectively. Results showed that the multilayer emulsion samples had larger particle size than simple emulsion. But the bacteria strain had no effects on the particle size of the samples. Span showed that the simple emulsion samples had more dispersion than the multilayer emulsions. Zeta potential of LR-ME, LR-E, LP-ME and LP-E emulsion samples was measured -51.26, -39.35, -56.65 and -30.25 mV, respectively. Multilayer emulsion samples had lower negative zeta potential than simple emulsion, but the bacterial strain had no effect on the zeta potential of the samples. Multilayer emulsion samples had higher stability than simple emulsion, But bacterial strain had no effect on the stability of samples. The bacterial counts in LR (free Lactobacillus rhamnosus), LR-ME, LR-E, LP (free Lactobacillus plantarum), LP-ME and LP-E were measured 8.49, 8.48, 8.51, 8.41, 8.37 and 8.39 log cfu/g, respectively. The results showed that coating with multilayer emulsion is the best method for increasing the viability of probiotics.

Quality losses during blanching can be minimized by adequately selecting the time-temperature schedule. In this study, the blanching process of blackberry fruits at 3 selected temperatures were investigated. The thermophysical properties were estimated based on the chemical composition of the sample. Convective heat transfer coefficient was also estimated using a new novel technique called inverse problem method. In order to determine the best model that can describe the shape of the fruit and predict accurately temperature changes during blanching, three analytical models based on solution of Fourierchr('39')s second law for heat transfer on regular shapes (sphere, 2D rectangle and finite cylinder) and a numerical model based on the real geometry of the sample were developed. The results showed that among the analytical models, the two-dimensional rectangle can better predict temperature changes at the center point of the sample than others. However, the developed numerical model was recognized as the best model due to the highest coefficient of determination (R²>99) and the lowest root mean square error (RMSE=0.37). By applying this model, temperature variations in the fruit can be predicted with high accuracy as a function of internal (thickness, and chemical composition) and external variables (temperature, and water bath velocity).
