In Farsi, the clitic pronouns are often added to the stem as the last element, but in some structures, they can be immediately attached to their hosts. The ability to describe this dual behavior can be used as a criterion to check the effectiveness of different approaches. This research aims to find out if Distributed Morphology and its post-syntactic mechanism are needed to determine the position of different morphemes at the level of the word? Or it can be explained using lexicalist hypothesis? For this purpose, after introducing the theoretical background and previous researches, we analyze data from Farsi, the analyses shows that the assumptions of lexicalists cannot explain why the clitic pronoun (shon) has two positions in (xodeshoniha) and (xodihashon), but this phenomenon is not allowed in other structures. On the other hand, by analyzing the data in the framework of Distributed Morphology, it was found that only with the existence of post-syntactic operations such as local dislocation and considering the content feature of clitics and stems the dual behavior of the clitic pronouns can be explained.

The central issue of the present paper is the study of the causes of the mother tongue decline in the Sahne city in Kermanshah province. The issue of language is beyond the dialect of people and is refer to the form of life and the matter of macroeconomic and political relations. From this perspective, the form of life and the language associated with it explain the praxis of the members of the society. The appropriate method of examining the problem should be able to analyze the justification of agents to their situation, that is why Grounded Theory is chosen as the method of this research and data analysis is taken from abduction reasoning. The results of the analysis introduced the categories of globalizing, modernizing, de-use of language, economic necessity and the government as the most important factors of local language fading. In this essay the meaning of globalization is the globalizing of special type of economic relation that explain other categories role in the process of fading of languages.

Identifying the constraining factors of production and yield gap is very important. Therefore; this research was performed to identify the production constraining factors of local rice cultivars. All management practices from nursery preparation to harvesting stages for 100 paddy fields of local rice cultivars were recorded through field studies, in Sari, from 2015-2016. In the CPA, the actual and calculated potential yield were 4495 and 5703 kg/ha, respectively and the gap was 1221 kg/ha. The yield gap caused by number of top-dressing variables was 324 kg/ha, equal to 27% of the total yield gap. The yield gap related to previous year of legumes cultivation was 218 kg ha-1, equal to 18% of the total yield variation. Among the 10 variables entered in the CPA model, the effects of top-dress fertilizer application and its application frequency and foliar application were remarkable, which could compensate a significant part of the yield gap (444 kg/ha, 37% of total) in the farmers’ fields by managing these variables. According to boundary line analysis (BLA) finding, actual yield mean on the basis of optimal limit related to 12 variables under study was 5369 kg/ha, with 881 kg/ha yield gap . Mean relative yield and relative yield gap for 12 variables (transplanting date, seedling age, number of seedlings per hill, planting density, nitrogen and phosphorous per hectare, nitrogen before transplanting, harvesting date, lodging problem, pest problem, diseases problem and weeds problem) were 83.64 and 16.35 kg/ha, respectively. Based on the finding, it can be stated that the model precision is appropriate and can be applied for both estimation of the quantity of yield gap and determining the portion of each restricting yield variables.

Traumatic dislocation of lisfranc joint is relatively rare. There have been many different subtypes and variations in this injury. We would like to report a variation of this injury in a 40 years old man who had lisfranc dislocation with simultaneous dislocations of first and second metatorsophalangeal joints. A two-year follow-up has been done.

This study aimed to evaluate the shoulder dislocation following tramadol-induced seizure and its potential difference with other shoulder dislocations. We evaluated six cases that used tramadol tablets and some of them had a history of seizure. All of the cases had shoulder dislocation. According to the findings, tramadol use and tramadol-induced seizure may increase the risk of shoulder dislocation.

Multi-label classification aims at assigning more than one label to each instance. Many real-world multi-label classification tasks are high dimensional, leading to reduced performance of traditional classifiers. Feature selection is a common approach to tackle this issue by choosing prominent features. Multi-label feature selection is an NP-hard approach, and so far, some swarm intelligence-based strategies and have been proposed to find a near optimal solution within a reasonable time. In this paper, a hybrid intelligence algorithm based on the binary algorithm of particle swarm optimization and a novel local search strategy has been proposed to select a set of prominent features. To this aim, features are divided into two categories based on the extension rate and the relationship between the output and the local search strategy to increase the convergence speed. The first group features have more similarity to class and less similarity to other features, and the second is redundant and less relevant features. Accordingly, a local operator is added to the particle swarm optimization algorithm to reduce redundant features and keep relevant ones among each solution. The aim of this operator leads to enhance the convergence speed of the proposed algorithm compared to other algorithms presented in this field. Evaluation of the proposed solution and the proposed statistical test shows that the proposed approach improves different classification criteria of multi-label classification and outperforms other methods in most cases. Also in cases where achieving higher accuracy is more important than time, it is more appropriate to use this method.

All materials are made up of sub-bodies, which constitute their substructure or microstructure. The size of a sub-body may vary from atomic dimensions to a macroscopic scale, such as grain size. Depending upon the nature and accuracy of the physical phenomena to be modeled, the average distance of the sub-bodies plays a central role. This distance may vary from the order of the lattice parameter (10-8 cm in perfect crystals), to a few millimeters, as in granular solids. The boundary and initial conditions bring into play another characteristic, length. Such models, entitled nonlocal theories, have been proposed for the past four decades. The solutions of various critical problems have veried our hopes and expectations in that, by means of nonlocal models, it will be possible to make accurate predictions of physical phenomena at submicroscopic scale. In the present study, the anti-plane stress field of multiple cracks is obtained using the solution of screw dislocation in an infinite elastic plane, based on nonlocal elasticity. The distribution dislocation technique is used to model the crack problem with screw dislocation distribution. Unlike the classical elasticity solution, a lattice parameter enters into the problem, which makes the stresses finite in the screw dislocation solution in the infinite elastic plane in nonlocal theory, which has no singularity at the dislocation tip, and which is consistent with theoretical results. Similarly, the crack problem using the distribution dislocation theory is solved with no singularity at the crack tip. The kernel in the related equation is of the Cauchy type, and to determine the distribution of dislocations, which generates traction along the crack line, the Gauss-Chebyshev quadrature has been used. Several numerical examples to illustrate the accuracy and capability of the solution have been calculated, where the effect of crack length, lattice parameter and constant is calculated as a variable parameter, which includes all of them. Stress at the crack tip and its graphs are depicted and the results obtained are compared with classical results in this field.

First carpometacarpal (CMC1) joint dislocations are uncommon injuries. However, they can limit hand functions and lead to serious complications. Herein, we report the case of a multiple trauma man with dorsal dislocation of thumb CMC joint that was successfully treated with closed reduction and casting. The patient was a 47-year-old male with multiple traumas complaining of right wrist pain. Tenderness, deformity, and reduced range of motion of the right thumb CMC joint were observed. X‑ ray showed dorsal dislocation of the CMC1 joint. Closed reduction of the dislocated joint was performed under general anesthesia, and the joint was immobilized by a thumb‑ spica cast for 14 days. The patient was eventually discharged in good condition and had no complications or manual dysfunction after a 1‑ month follow‑ up. The optimal management of the CMC1 joint dislocations is controversial. The closed reduction seems adequate for these injuries. However, patients whose joints remain unstable after closed reduction, especially those with manual activities, should be considered for open reduction and surgical ligament repair.
