This research conducted in order to prioritize the effective criteria on development of medicinal plants cultivation in North Khorasan Province using Analytical Hierarchy Process (AHP) and Delphi methods. For this purpose, a list of effective factors offered to delphi group. Analysis of delphi process showed that among 23 offered factors 19 factors, had greater impact on development of medicinal plants cultivation. Hierarchy tree was drawn through grouping of 19 factors into four criteria including economic, promotional-educational services, cultural-social and supportive policies factors. The pair wise comparison questionnaires were then distributed among relevant researchers and experts of the province to get their opinions about the priority of criteria and sub- criteria. The questionnaires were analyzed using Expert Choice software. The result revealed that economic criterion with respective weight of 0.406 had the most impact among four criteria affecting the development of medicinal plants cultivation. The supportive policies (respective weight of 0.275), educational-extension services (respective weight of 0.193) and cultural-social factors (respective weight of 0.125) received the maximum towards the minimum priorities, respectively. The results of synthesis process showed that among the 19 factors, the guaranteed purchase and establishing of pilot fields of medicinal plants, farmers' awareness of comparative advantage of medicinal plants, and the development of processing industries had the maximum towards minimum impacts on development of medicinal plants cultivation.

Germination is a critical stage in the life cycle of plants and often controls population dynamics, with major practical implications. Salsola arbusculiformis is one of the most important plants used to prevent soil erosion and a good fodder resource for sheep and goat in the rangelands of Iran. However, the species seems to have low seed germination, so the purpose of this study was to investigate the effects of different treatments to improve its seed germination. Three concentrations of gibberellic acid (100, 500 and 1000 ppm), mechanical scarification with sandpaper, concentrated sulphuric acid (H₂SO₄ (98%)), potassium nitrate (KNO₃ (0.2%)), thiourea one Molar, four prechilling periods (10, 20, 30 and 150 days at 2 °C) were used as study treatments and distilled water as control. The results showed that there were significant differences (p<0.05) among and within the treatments in their effects on seed germination. The effective treatments to stimulate seed germination were prechilling for 150 and 30 days; sulphuric acid and sandpaper scarification. Prechilling for 150 and 30 days increased germination by 88.4% and 85.65%, respectively, while sulphuric acid and sandpaper scarification both increased germination by 76.1% compared to the control. The results also showed that gibberellic acid, potassium nitrate and thiourea did not promote seed germination. It was inferred that the most effective treatments among the methods used for breaking seed dormancy of Salsola arbusculiformis were prechilling for 150 days and mechanical scarification by hand with sandpaper.

Targeting followed by pattern making and planning to reach to goals is a necessity in all societies. Urban planning, as a subject expressing interactions between mankind, culture, living style and environment, plays an important role in reaching to the Islamic society goals along with keeping the original identity and promoting the culture and ethics, and consequently is very important in preparing a local model based on the Islamic teachings appropriate to the Islamic-Iranian context. Islam has paid special attention to social issues; just do not discuss individual aspects only. Way to achieve prosperity has been the establishment of an Islamic community and Change and growth, resulting in a society where people of all decisions and activities have been. In the Quran, Allah does not change the destiny of any nation unless they themselves. Issues such as community participation, social justice and components - such as these are placed on the social dimension of the Quran and hadiths emphasize. On the other hand Iran has long ago been important social issues and it has Construction of public buildings in the city and had a significant role. In this paper, after reviewing the literature about the social aspects of urban planning, we explained the social components of Islamic-Iranian urban planning pattern of progress. Accordingly, factors like security, social justice, health, neighborhood etc. were introduced as the important elements in social considerations of Islamic-Iranian urban planning pattern, based on Islamic teachings and Islamic-Iranian urban planning history and background .Each of the components of the urban social Iran - Islamic has a different degree of importance,some components may all components in its place and Or even creator them to be. The components and their corresponding degree of importance based on Islamic perspectives are examined. The social concepts such as privacy, health, social justice, security, peace and tranquility and also emphasized the teachings of Islam and the Islamic Republic of Iran has been in the planning And can serve as guides and tips for Islamic and Iranian urban spaces, enhanced quality of life, increased social interaction, participation of residents in the neighborhood, social justice and economic prosperity can be used. Create a semantic framework that is based on the principles expressed in the social body based on the ideas of God and to lead. Therefore, the physical space of architecture and urbanism in shaping the framework and components manufacturer must identify and examine their relationships and to build on the structure of the physical space of cities. Urban planning, urban design, architecture and industrial design matters and social climate will affect the Iranian Islamic cities. These components are not only social prosperity,social equity,increase physical qualities, enhancing the sense of belonging to the environment, but also contribute to the increased value of land, recreating the old quarters of cities and economic issues influence is remarkable.Urban pattern recognition component of Islamic and Iranian decision-makers and decision-makers, the public,and what to get rid of the confusion of spiritual and material life of man,it is important to define it.

This study investigated intra-specific variation in the growth parameters and dry mat-ter partitioning of sugar beet cultivars at different levels of salinity (0, 50, 150, 250 and 350 mM NaCl + CaCl2 in 5:1 molar ratio) using four cvs, one British (Madison) and three Iranian cvs (7233-P12, 7233-P21 and 7233-P29). The plants were grown in a controlled greenhouse environment for about 18 weeks. Although growth parameters such as leaf area and dry matter accumulation were stimulated or unaffected at a low level of salinity (50 mM), higher salt concentrations significantly decreased all growth traits. At a high level of salinity, cv P29 showed a significantly higher leaf area and total dry matter than others at 16 weeks of salt treatment. Pre-dawn leaf-water potential (ΨL) and shoot water content (SWC) were decreased by salinity. Cvs Madison and P12 had significantly lower ΨL (more negative) and shoot water content at high levels of salt treatment (250 and 350 mM), while P29 and P21 showed higher ΨL (less negative) and shoot water content at the same salt concentrations. Analysis of ion accumulation revealed that Na+ and Cl- contents were greatly increased in leaves under saline conditions. However, salt tolerant P29 had lower Na+ and Cl- concentrations than other cvs at high levels of salinity. The root dry matter of sugar beet cvs at the lowest and the highest salt concentrations reduced by 23.3% and 89.8%, respectively compared to the non-stressed plants, while shoot dry mat-ter decreased by 1.1% and 77% at the same salt concentrations, respectively, after 16 weeks of salt treatment. The pattern of dry matter partitioning to different parts of the plant was changed by salt stress and the dry matter allocated to the storage roots was re-duced by 6% and 18% at the lowest and the highest salt concentrations, respectively, at 16 weeks after salinisation.

Yeki Bud Yeki Nabud, a story collection written by Mohammad Ali Jamalzadeh (1892-1997), marks the beginning of modern short story in Iran. Along with the stories in this collection, also known as the very first attempts to write Persian short story, the foreword to this book is of prime importance in Persian literary studies and literary theory. One of the basic and yet significant concepts of this foreword is “literary democracy.” The analysis of the micro-concepts and metaphors developed in this foreword helps us analyze this particular macro-concept and hence better understand the foundation for the notion of “literary democracy.” It is also important to note to what extend this macro-concept have played a role in modern Persian literature.

This study investigated the variation between two sugar beet (Beta vulgaris L.) cultivars with respect to growth parameters and photosynthetic rates of individual attached leaves during salinization. Sugar beet plants grown in sand culture were gradually exposed to different levels of salinity (0, 50, 150 , 250, and 350 mM, NaCl+CaCl2 in 5:1 ratio). Salt concentrations significantly decreased all growth traits. At the highest level of salinity (350 mM), cv 7233- P29 showed a significantly higher leaf area and total dry matter than Madison after eight weeks of salt treatment commencment. Net photosynthesis (ACO2) and stomatal conductance (gs) were strongly affected by salinity. The Na+ and Cl- concentrations in shoots significantly increased as salt concentration increased. Net photosynthesis (ACO2) was plotted against computed leaf internal CO2 concentration (Ci), and the initial slope of this ACO2-Ci curve was used as a measure of photosynthetic ability. Leaves from plants exposed to 50 mM salinity showed little change in photosynthesis, whereas those treated by high levels of salinity had up to 91.5% inhibition in photosynthetic rates and an increase in CO2 compensation point. Leaf chlorophyll content increased with increasing salinity. Although partial stomatal closure occurred with salinization, reductions in photosynthesis were partly non-stomatal at high levels of salt treatment.

Khandidani [to be read and seen at the same time] is a kind of poetry that has an inseparable connection with visual arts. Mehrdad Fallah, as an Iranian contemporary poet, has been focusing on the written /performative aspects of poetry rather than its spoken aspects, which is manifested in the form and structure of his poems. Fallah introduces Khandidani as “rediscovering writing and writing symbols’’ which converts to ‘’stage poetry” in the process of reading and seeing the poem. The primary assumption of the current paper was that the initial idea of Khandidani was formed under the influence of the world literature, and in particular Guillaume Apollinaire, who was mainly interested in the written form of the poem, painting and cubism. It should be mentioned that there are also instances in classical Persian poetry which utilized some of the techniques that Fallah employed in his poetry. In the current paper, the inter-artistic, intertextual and comparative basis of such poetry was studied. Moreover, it was clarified that how the poem is read and seen on both sides of the poet/ reader dichotomy.

A factorial pot experiment based on randomized complete blocks design with four replications was carried out in order to evaluate salt tolerance of four sugar beet cultivars including Madison (British origin) and three Iranian cultivars (7233-P12, 7233-P21 and 7233-P29) using carbon isotope discrimination (Δ). Plants were grown in sand culture medium in greenhouse conditions. Sugar beet cultivars were irrigated with saline water (tap water as control, 50, 150, 250 and 350 mM of NaCl and CaCl2 in 5: 1 molar ratio) from 4-leaf stage for 16 weeks. Carbon isotope discrimination significantly decreased with increasing salinity. Significant differences of Δ between shoot and root were observed in all cultivars and all levels of salinity. Madison cv. showed lower Δ in shoot and root than the other three cultivars at all levels of salinity except the control, but cv. 7233-P29 had significantly higher Δ values at saline conditions of 150 mM and above. Although the regression of Δ and Ci/Ca was positive, the slope of regression line was different from the pattern predicted by theory, indicating an underestimation of Δ in these samples. Relatively higher 13C (lower Δ) was found in root as compared with shoots.

Due to the importance of acoustic response control of submerged vibrating structures, in this study,the optimization of acoustic power radiation from a square stiffened plate under harmonic loading was investigated.Since one face of the plate is in contact with water, a fully coupled analysis was used. The effect of fluid in the analysis was considered via added mass matrix. The added mass matrix was obtained based on both Rayleigh integral and the boundary element approaches.The obtained added mass matrix was then added to the mass matrix of the structure calculated from the finite element discretization of plate. Several variables such as acoustic pressure at specific points and also radiated power were calculated. Results show good agreement between obtained results from the Rayleigh integral and the boundary element. To reduce the radiation power, dynamic absorbers in the form of lumped mass and mass-springs in specific locations on the plate surface were considered. Because optimization procedure requires several evaluation of cost function in the design variable space, model reduction can save a great amount of computation efforts. Therefore, the truncated modal matrix was employed and its effectiveness and precision on the obtained results was studied. Finally, Genetic Algorithm (GA) was used for minimizing the appropriate goal function in three case studies: concentrated mass on cross-points, dynamic absorbers on cross-points and combination of two former cases.All the studied cases resulted on significant reduction in the goal function index.

— In this paper, we consider 5G as an evolution of 4G, thus we propose logical connections between LTE-A entities such as SGW, PDN firstly. Then, we present a new configuration and accordingly data/control realization of 5G EPS (Evolved Packet System) based on a carrier-grade hypervisor and an intelligent core server (IC server) to provide virtualization and flexibility to the network. In addition, we define two new entities hAN (heterogeneous access network) and TNT-Gateway (TENANT Gateway) for access and core, respectively and define their functions and data/signaling connections. Some important advantages of these configurations are: 1) cost reduction, 2) network efficiency improvement, and 3) increase of network flexibility and service availability which approaches LTE to 5G.

In this research, flax seed mucilage was extracted. Composite film of sodium alginate and flax seed mucilage was prepared. Norbixin pigment and tungsten oxide (WO3) nanoparticles were used to modify the film structure. The color, crystallite, thermal and mechanical properties of the films were investigated. Also, the antibacterial properties of the prepared films against Escherichia coli and Staphylococcus aureus bacteria were investigated. The obtained results showed that the pure alginate/mucilage film does not have very high transparency, which is reduced by adding tungsten oxide nanoparticles and norbixin pigment. The effect of tungsten oxide nanoparticles in reducing film transparency has been greater than that of Norbixin. Examining the factor a (green-red) shows that this factor has increased with the increase of Norbixin and tungsten oxide nanoparticles. Examining factor b (blue-yellow) shows that with the increase of Norbixin and tungsten oxide nanoparticles, this factor has increased. By examining the XRD spectrum of the pure alginate/mucilage film, it was found that this film showed two broad peaks at 2θ of 10° and 20°, which indicates the relatively amorphous structure of this film. In the alginate/mucilage film modified with tungsten oxide nanoparticles, the peaks related to the crystalline nanoparticles in 2θ of approximately 25, 30, 35, 40, 50, 55 and 65 degrees are quite clear, which shows that these nanoparticles improve the crystalline structure of the film. By examining the TGA curves of the films, it was found that the addition of tungsten oxide nanoparticles and norbixin pigment increased the thermal stability of the film. Examining the antibacterial property of the films showed that the addition of tungsten oxide nanoparticles and norbixin pigment increased the antibacterial property of the film significantly (p<0.05).
