One of the genres of folk literature is non-narrative literature including poems, tales, riddles, parables, and fables. In terms of form and diction, these are classified into songs, odes and lullabies. Folk songs may be considered on the basis of their subject matter, style and composer’s spirits. Iranian songs of this type are characterized with natural hilarity, emotional sincerity and poetic salubrity. The province of Kohgiluyeh and Boyer-Ahmad is located in the southwest of Iran, divided into hot and cold areas. The dialect spoken in this region is Boyerahmadi which is a little different across the province. As one of the closest versions of the Persian language, the dialect is believed to be an offspring of the Middle Persian. A comparison of syntactic and lexical structures of Lori dialect and the standard Persian dialect show that both derive from the Sassanid Middle Persian and further back from the Old Persian. This paper aims at Kohgiluyeh and Boyer-Ahmad folk poems in terms of themes, contents, and aesthetic features. It specifically focuses on Sherveh and its origin in southern Iran as well as amorous songs and lullabies. These issues are discussed through classification and illustration.

Increasing complexity and turbulence of environment, are requiring quick response and proper reaction of organizations. These conditions have increased the need of organizations to think and act beyond just solving their current issues. In today's competitive and changing environment, being and acting smart are the best guarantee for any business to success. Present study seeks to answer the question of what the processes are and what factors are necessary for smart organization. This paper is based on descriptive- survey methods, and of purpose is fundamental - applicable research. The statistical population is consist of 3531 people from manufacturing firms in a company and 347 of them were chosen as a sample. Data was gathered using a questionnaire and Delphi technique was used. To analyze the data, partial least squares method used by Smart PLS software. Test results showed that all variables had a significant and positive impact on the smart organization, except group work, and the effect of all variable together is significant. Also found out that flexible communications has greatest impact on the smart organization.

Aims: The purpose of the research is to identify strategies for green adaptive reuse of the shared-heritage of Iran and Germany which were built during WWI and WWII in Mazandaran, and to identify the role of green adaptive reuse in the sustainable development of local communities. The research is to identify the effective components in green contemporization of Mazandaran industrial heritage buildings, and the impact of each criterion on the sustainable development of local communities.
Methods: The AHP method is adopted to evaluate the opinions of the experts by combination of questionnaire and the Delphi method. By examining the industrial heritage of Mazandaran and comparing its position with similar cases, the effective components of the green contemporization process were prioritized.
Findings: The industrial heritage of Mazandaran including the Babol cotton factory with 26.6%, the GhaemShahr textile factory with 21%, the Naseri-way with 20.6%, the Chalous-Metal-Bridge with 16.8% and Lar-Stone-Bridge with 15.5% will be effective in development of the local communities of Mazandaran by means of development of tourism.
Conclusion: The development of industrial heritage with the priority of sustainable social development leads to the development of local communities. The conclusion emphasizes on the priority of tourism development by creating access security, possibility of sale, public and private arena, optimal use of the ruined area, creating a multi-purpose use and organizing commercial units, as well as cultural development with protection of works, integrated development, holding cultural activities will play an effective role in the development of local communities in Mazandaran.

Anti-lock braking system (ABS) prevents the wheels from being locked in hard braking conditions and reduces the vehicle stopping distance to the minimum value by regulating the tire longitudinal slip at its optimum value. This paper presents a two-layer controller for ABS of trucks which is adaptable with different road conditions. In the upper layer, a fuzzy controller is designed to calculate the optimum longitudinal slip of each wheel for which the maximum braking force is achieved in different conditions. In the lower layer, a nonlinear controller is analytically designed based on the predictive method to track the optimum wheel slips calculated from the upper layer. In order to increase the robustness of the controller in the presence of system uncertainties, the integral feedback technique is also appended to the predictive method. All simulation studies are conducted using the professional software of Truck Sim to evaluate the performance of the controlled system in a real condition. The results show the effectiveness of the proposed control system in improving the braking performance of trucks in different road conditions.

One way to control the position of the missile is controling thrust vector that is moves with help of thrust due to exit of gas. All thrust vector control (TVC) methods are independent of aerodynamic forces of atmosphere and until the engine has thrust, maintain their performance. Secondary injection systems are one of the four major TVC methods. In this study,at first identify the components and design entire conceptualdesigning of system and the preliminary design of manifold of a type of thrust vector control system using a liquid injection thrust vector control (LITVC)has been proceed. Then the layouts of components on some components such as injectors and reservoirs, as well as detailed design of the system are discussed. Then the numerical simulation of flow and the designing and studying the sprayers in LITVC systems will be discussed. Also numerical designing and simulation in two parts: injection system and the injector spray effects into the main flow are analyzed and the results are presented and validated. The achievement of this study can be used as a model for designing and analyzing of various kinds of TVC systems with lateral fluid method on a variety of missiles with different launchers.

In the present study, the use of the ultrasonic apparatus has been investigated in the extraction process of Hypericum perforatum L. flowers. The effect of methanol to water ratio (24.77, 35, 50, 65, and 75.22 percent), time (1.59, 5, 10, 15, and 18.40 minutes), and temperature (24.77, 35, 50, 65, and 75.22 °C) on the extraction of phenolic compounds, flavonoids and antioxidant activity of the extract using two methods of 2,2-diphenyl-1-picrylhydrazyl (DPPH%) and (FRAP) Ferric Reducing antioxidant power (FRAP) were studied using the response surface method and central composite design. The results of RSM showed that the highest extraction efficiency was obtained at 50% methanol/water ratio, 70 °C, and 15 min. Under optimal conditions, the corresponding values for total phenol content, total flavonoid content, and antioxidant assays of %DPPH and FRAP were 28.46 (mg gallic acid equivalent (GAE) g^-1 dry weight (DW)), 19.75 (mg quercetin g−1 DW), 89.23 (%DPPH), and 3.57 FRAP µmol Fe++ /g DW respectively. In addition, results express the effectiveness of the proposed conditions and reliability of central composite design analysis on the extraction of phenolic antioxidants from H. perforatum flowers. Using ultrasonic is a low-cost, simple, and efficient method for the extraction of phenolic antioxidants, which increases the extraction efficiency and thermal protection of phenolic antioxidants.
