Part of what we know as the heritage of Iran and India has originated from the Indo-Iranian culture, and this heritage belongs to the East and the common life of Indo –Iranians in the past. We can consider the similarities between Arash-e Kamangir in Iranian mythology and Vishnu in Indian mythology as an original example in this case. In this research, we try to show the characters of Arash-e Kamangir, in the ancient, middle and Islamic periods, according to the comparative method in the French School and the method of content analysis. The results of the research show that Arash and Vishnu are two myths that have a common origin, and consequently, they have vast and widespread common aspects; and in making of mythological character, the subject of the attack between Good and Evil has a special place in the two cultures. Being warrior god of rain in creating the myths like Arash and Vishnu; being bodily and their connection with natural elements and heavenly realms are the other results obtained in this study.

Background: Leptospirosis has been recognized as an important reemerging infectious disease caused by pathogenic Leptospira spp. A major challenge of this disease is the application of a basic research to improve diagnostic method. Outer membrane proteins of Leptospira are potential candidates that could be useful in diagnosis. Among them the lipL41 is an immunogenic protein which is present only in pathogenic serovars. In order to evaluate genetic conservation of the lipL41 gene, we cloned and sequenced this gene from Leptospira interrogans serovar Canicola.
Materials and Methods: Following the DNA extraction from the serovar, the lipL41 gene was amplified and cloned into pTZ57R/T vector and transformed into the competent E. coli (Top10). Recombinant clones were confirmed by colony PCR and DNA sequencing. The related sequences were then analyzed and compared with the sequences in the Genbank database.
Results: PCR amplification of the lipL41 gene resulted in a 1065 bp PCR product. The PCR based on the lipL41 gene detected all the pathogenic reference serovars of the tested Leptospira spp. It was revealed that in Iran the homology of the lipL41 gene between vaccinal and clinical serovars of Canicola was 100%. It also showed >95.9% homology with other pathogenic serovars in Genbank database, which indicates genetic conservation of this gene.
Conclusion: Because of the conservation of lipL41 gene among different strains of Leptospira and its exclusive presence in leptospira, it was revealed that the cloned gene could be further used as a good candidate for developing diagnostic methods such as ELISA and as positive control in diagnostic PCR.

 to enhance the closed loop performance in presence of disturbance, uncertainties and delay a double loop mixture of MPC and robust controller is proposed. This double loop controller ensures smooth tracking for a 3-axis gyro-stabilized platform which has delay intrinsically. This control idea is suggested to eliminate high frequency disturbances and minimize steady state error with minimum power consumption in simulation and experiment. Proposed controller based on the combination of ℋ₂ and ℋ_∞ controllers in the inner control loop shows the robustness of the proposed methodology. In the outer loop to have a good tracking performance, an integrated MPC is used to handle delay in system dynamics. Also, the main idea for dealing with uncertainties is using integral and derivative of platform attitude. In the proposed platform, the ℋ_∞ controller is compared with ℋ_∞/ℋ₂ controller in KNTU laboratory in theory and experiment. Results of experimental set up shows the same reaction of two controllers against disturbance and uncertainties in delayed system.

In this paper, the problem of decentralized model reference adaptive control (MRAC) for a class of large scale systems with time varying delay in interconnected term and input and state delays is studied. To compensate the effect of input delay indirectly, a Smith predictor built on. To handle the effects of the time delays in input, the adaptive controller part includes two auxiliary dynamic filters with time varying gains. Under a usual assumption that the interconnections are assumed to be Lipschitz in its variables and uniformly in time with unknown Lipschitz gains, the difficulties from unknown interconnections are dealt. A generalized error is defined and by a suitable Lyapunov function, an adaptive controller is designed to stabilize it. Decentralized adaptive feedback controller can render the generalized error system uniformly ultimately bounded stable is designed. Finally, a numerical example is given to demonstrate the feasibility and effectiveness of the proposed design techniques.

Abstract: A large number of slabs (floor and roof) in industrial and residential buildings were constructed by steel I-beam, brick Jack arch slab in Iran. Jack arch masonry flooring system consists of a number of closely-spaced, parallel steel I-beams and a number of shallow brick arches filling the spaces between the steel beams. The spaces over the arches are then filled to create a flat floor. This kind of slab did not indicate suitable reaction during past earthquakes. Collapse of a large number of these non-homogeneous one-way slabs during past earthquakes has highlighted their poor seismic performance. They do not behave as rigid elements. However, due to their easy construction together with low cost, the jack-arch slab is still widely used in many countries. Thus it is necessary to study the rigidity of this kind of slabs by more accuracy. The objective of this paper is to evaluate the rigidity of the jack arch slab and influence of X-shaped bars and top layer concrete in their rigidity using nonlinear analysis (Ansys software). Finite element numerical analyses are then conducted to investigate the effects of a number of parameters on the rigidity of the slabs. In addition, appropriate tables and figures are presented to facilitate the investigation of the jack arch slabs. For this purpose, several steel-framed structures constructed by jack arch slab with different terms were selected. These terms consist of, number of buildings stories (one, two and three stories), diameter of bars (14, 16, 18 and 20 mm), thickness of top layer concrete (6, 8 and 10 cm) and different areas of slabs (3.6×3.6, 3.6×4.5, 3.6×5.4 and 3.6×6.3 m). To consider the rigidity of slabs, the 2800 standard's regulations were applied. According to the rules and regulations of standard no. 2800, the slab will be rigid if the ratio of relative story displacement and diaphragm displacement to be less than 0.5 and the slab will be flexible, if this ratio to be greater than 0.5. The result of an experimental model was used to clarify the result of this research. It was shown that the result of experimental model was in conformity with this research one. At the end two expressions was suggested for determination of bars diameters and the concrete layer's thickness needed for rigidity of jack arch slab

Campylobacter is known to be one of the most common causes of human intestinal disorders. Since poultry are known to be the main reservoirs for this pathogen, decreasing this bacterium in intestinal tract could be beneficial in reducing contamination of poultry products. The effects of probiotic (PrimaLac^®), medicinal plant (Sangrovit^®) and organic acid (Selko-pH^®) as broiler feed additives on cecal colonization, and fecal excretion of broilers were studied. Other parameters such as performance, immune response and intestinal morphology were also determined. A total of 300 broiler chicks (Cobb 500) were divided into 5 groups. Groups consisted of unsupplemented feed (negative and positive controls), probiotic, medicinal plant and drinking water containing organic acid mixture. Except for the negative control group, all chickens were orally challenged with (10⁹ cfu mL^-1) Campylobacter jejuni at day 21. Cecal and fecal samples were collected for Campylobacter count. Body weight (BW), feed intake (FI) and feed conversion ratio (FCR) were determined weekly and cumulatively. BW and FI in the probiotic treated group were higher (P< 0.05) than the positive control group. On day 49 all supplemented treatments showed a reduction of Campylobacter colonization in cecal contents (P< 0.05). Fecal samples showed reductions (P< 0.05) on day 35 and 42. Villi height of duodenum and jejunum in the probiotic and medicinal plant treated groups were improved (P< 0.05). Immune response was significantly higher in these two groups (P< 0.05). These effects could be due to the antibacterial effects of the used feed supplements. Our results indicate that these feed additives could be potential treatments for reducing Campylobacter in the intestine of broilers. Probiotic and medicinal plant improve growth performance of these birds.

In the present study numerical simulation of synthetic jet is performed to optimize geometric parameters and excitation frequency to maximize mass flow rate and velocity of the jet and to avoid separation on the airfoil. Geometric parameters include: diameter and height of the cavity and orifice and excitation frequency of diaphragm which are selected as variable parameters for optimization. Using Response Surface Method (RSM) in this research, the simulations for optimization of the momentum of jet flow are designed. After studies and initial simulations, the range of variations in the effective variable parameters for the maximization of the target function (jet velocity and mass flow rate) are determined. Then, using the RSM, 32 separate tests are defined based on geometric and frequency parameters to find a second-order relationship, which relates the target functions to their variable parameters and their interactions. In this case the RSM prediction for the maximum velocity and mass flow rate of the jet are 22.16 m/s 0.0006 kg/s, respectively. Using RSM to optimize the geometric parameters and excitation frequency, jet momentum increases considerably in comparison with the first simulation. The velocity, mass flow rate, and momentum of the jet are increased by 31%, 36% and 78%, respectively.

In this paper, a new Multiple Model Adaptive Control (MMAC) is proposed to control of the satellite antenna position with time varying input delay. Selecting of adequate delay estimation method and weighting algorithm using delay estimation error are features of proposed controller. Input delay can be effect on the performance of the closed loop system and if delay time is unknown and time varying, the closed loop system will probably be unstable. At these cases, delay time must be identified to adopt control signal. It is assumed that upper bound of the delay time is known. Delay time is divided into several small bounds and then an adequate PI controller is designed for each bound to guarantee closed loop system performance and stability. In the on-line mode, delay time is identified by adequate estimation algorithm and the control signal is constructed by a weighted sum of the designed controllers output. Control signals weights are a function of the absolute error between the estimated and the average delay time in each bound. Performance of the proposed method and stability of closed-loop system is assessed using several simulations of the system. Simulation results confirm the effectiveness of the proposed algorithm with respect to conventional PI controller.

Abstract. One of the most vital, essential human being requirements is water, which it has become increasingly sensitive owing to population growth, the need to develop agriculture and industry, and restriction in water resources. Considering this, the need to store water and to use its potential for generating hydroelectric power, which it can be achievable by constructing dams, will be necessitated. Concrete dams play a significant role in Infrastructure in each country. One important part of dams exiting in the world are made of gravity dams and earthquake seems to be the major threat for them in earthquake-prone areas. Hence, the dam fracture, with much stored water, might have brought many conspicuous threats about in these zones. Also, any structural damage could lead to some negative economic effects. These facts have increased the scholars’ attention to the mechanical behavior of dams during the decades. The Seismic analysis of gravity concrete dams, usually, had been considered in an ideal form by means of 2D Monolith in mechanism design and an earthquake effect coefficient. Lately, the research focus, however, has been more on linear time history analytics and fracture analysis of concrete dams in 3D. The numerical modelisation of huge structures such as dams is a proper tool for Seismic analysis and performance evaluation. The valley shape is one of the important parameters in the selection of the dam structure. This parameter plays a crucial role in both Seismic stimulation and its results. In this paper, a 3D finite element model of Pine-flat gravity dam, without interruption seams with a non-linear behavior of the dam’s material, is considered. . Loading has two stages: static and dynamic. In this modelisation, static loading includes both the weight of dam body and the load of filled Hydrostatic tanks. After static loading, loading of Seismic dynamic is begun. Owing to the importance of valley shape, the changes/ deformations of valley width and the dam response to every three elements of ground is investigated. The impact of the ratio changes of width in dam height, as well as the importance of the transverse component of ground motion, along the vertical and horizontal, has been explored. Interaction effects of dam-reservoir-foundation is considered in the considered analysis and ultimately, the output of which is compared with two dimensional model results. The aim of this study is comparing two and three dimensional seismic response of concrete gravity dams and also necessity of providing more realistic models for considering the effects of cross stream modes. Also, not only are interaction effects of dam-reservoir-foundation, the nonlinear behavior of concrete, studied different Valley shapes, and the effect of them on non-liner response investigated, but also the Seismic stability of gravity concrete dams under longitudinal, vertical and the chosen transverse record earthquake are separate and simultaneously studied. The effects of dam-reservoir-foundation interaction, nonlinear behavior of mass concrete, also different shapes of valley are studied and their effect on nonlinear response and seismic stability of concrete gravity dams are evaluated under two and three-component earthquake records.

The fall of Baghdad and the destruction of the Abbasid caliphate by Hulagu Khan provided a fertile ground for Iran's independence and the re-emergence of Iranshahri political thought. Changizi Shahnameh, Mostufi’s Zafarnameh and Tabrizi’s Shahanshahnameh are the most important historical epics composed in the court of the Ilkhanate. The main purpose of this study is to examine the approach of the poets of these historical poems to the event of the conquest of Baghdad and how this event and the historical figures were described in these works to determine the extent to which the poets had an Iranian or religious view in interpreting this event. Examination of this poems shows that despite the similarity of the narrative, two different approaches are seen in these works: Kashani and Tabrizi have a more triumphant and Iranian-oriented approach to this event. Instead of considering the annihilation of the Abbasids as a historical tragedy, they consider it a fateful and natural thing in order to fulfill the Iranians' long-held desire for independence. Mostufi has a religious view of the conquest of Baghdad and has repeatedly expressed his grief and sorrow over the fall of the Abbasids. Of course, all three poets in the narration of the conquest of Baghdad paid attention to the political thought of Iranshahri and tried to introduce Hulagu Khan as a king in the thought of Iranshahri by attributing the outstanding attributes of the ideal Iranian king to him. On the other hand, by highlighting traits such as irrationality and stinginess in the Abbasid caliph, they show that he is not worthy of ruling.
