Prangos ferulacea (L.) Lindl. (Umbelliferae family) is a dominant species in the some partial of habitats in Zagros Mountains. According to ethno-botanical studies, this plant is one of the best range plants of Iran. Local ranchers collect green Prangos while it is toxic. They then dry the plant and use it to feed their livestock, especially in winter season. This research done to analyse the changes in the chemical composition of Pr. ferulacea with the effects of time, location and type of secondary metabolisms. Therefore, the ingredients and amounts of the essential oils of Prangos were studied during the growing and flowering stages (in both green/fresh and dried forms) to track such changes. The results showed that the amounts of terpinolene, β-phellandrene and bornyl acetate were decreased in the dried form, and some of the harmful components, such as α-pinene, β-pinene, myrcen and delta-3-carene, were absent, rendering the plant non-toxic. These results confirm the opinion of the ranchers. In the growing stage, the amount of coumarin was significantly less than in the flowering stage, which also supports the conduct of the local ranchers who gather the plants at the most appropriate time.

In recent decades, literary works have been considered as one of the important parts of documents, which is an analyzable part by sociologists for studying about the society, culture and politics. “Sayyed Ashraf Guilani”, with the nickname of ’’Nasim-e Shomal’’ - who has a newspaper with this name- has had a great role in the brightness of Mashroteh period. Sayyed Ashraf has many poems about the events of Mashrooteh. In this study, it has been tried to show the way of reflecting the sociological and political works of Mashrooteh period in the poems’ of Sayyed Ashraf with a literal sociology way and also using the general asterisks of Exchange Theory of Peter Blau. For using this theory, which is a compact of the sociological behaviorism and sociological realities, first of all, different aspects of the Mashrooteh period’s poems, Sayyed Ashraf’s poems from the beginning of Mashrooteh to the beginning of Reza Khan period autarchy kingdom are been investigated. Then thesy poems has been divided into three groups: 1- criticism, interchangeable poems, 2- organizing, veneration poems, and 3- cognizance poems. The last aim of this study is to analyze the effect of Sayyed Ashraf on Mashrooteh movement based on the sociological theories to show the completed stretchers of unity between the revolutionaries and the people in Mashrooteh period.

Research subject: Global warming is the most important worldwide problem. CO₂ is one of the greenhouse gasses and its emission to the atmosphere causes global warming to increase. Porous adsorbents are great candidates for CO₂ adsorption and graphene aerogels are porous nanostructures with very low density and hierarchical porosity which is suitable for CO₂ adsorption. The source of pristine graphite for graphene oxide synthesis as a precursor plays a vital role in graphene aerogel nanostructure.  
Research approach: In the current study, graphene oxide by modified Hummers method was synthesized with three different graphite sources. Graphene aerogels were prepared with synthesized graphene oxides via hydrothermal and freeze-drying methods to investigate their effect on graphene aerogel nanostructure. Finally, the CO₂ adsorption of graphene aerogels was evaluated. The samples were characterized by FTIR, XRD, SEM, and BET analysis.
Main results: The results indicated that the source of graphite has a significant role in the process of oxidation of graphene oxide by the modified Hummers method. XRD results of graphene oxides showed successful oxidation of graphite. The normalizing FTIR peaks of graphene oxides showed different intensities of oxygenated functional group peaks. FE-SEM results of graphene aerogels showed that less oxidation of graphite powder caused agglomeration of graphite plates and thick walls were formed. The macropore size in the structure of obtained aerogels (GAB and GAE) was 2.28 and 3.84 µm respectively which affected the CO₂ adsorption. Larger pores led to easier mass transfer of CO₂ molecules and higher CO₂ adsorption was achieved. Moreover, the high meso and micro surface area (111 and 115 m²/g respectively) in GAE increased CO₂ adsorption up to 1.04 mmol/g compared to GAB (0.724 mmol/g).

         In systemic functional typology, which studies the systems of languages rather than the whole languages, linguists strive towards empirical generalizations that in principle apply to all languages around the world. In line with the above-mentioned goal of systemic functional typology and having examined the ideational (logical and experiential), interpersonal, and textual systems of the ‘clause grammar’ of different and various languages, Matthiessen (2004) has achieved a series of typological generalizations/universals. In connection with his proposed typological generalizations, Matthiessen (2004) has argued that they can be applied in the description of any language and in the attempt to expand the typological explanations in the framework of systemic functional grammar as well. However, he has immediately stated that “It is not yet possible to propose a generalized map; but we have to move in that direction.”
         In line with Matthiessen’s claim mentioned above, the present paper has attempted to describe the THEME system of Azeri Turkish on the one hand and compare it with the THEME system of Persian language on the other hand. This research has been conducted in terms of the following three typological parameters concerning the THEME system: (1) The treatment of unmarked and marked THEME (related to the subsystem of THEME MARKEDNESS), (2) The relationship between THEME and MOOD (related to the subsystem of THEME SELECTION), and (3) The relationship between experiential (topical) THEME and interpersonal and textual THEME (related to the subsystems of THEME TYPE, INTERPERSONAL THEME, and TEXTUAL THEME).
         Studying typological behaviors of the Azeri Turkish THEME system in the framework of Matthiessen (2004)’s typological generalizations and comparing those behaviors with the typological behaviors of the Persian THEME system show that the two languages of Persian and Azeri Turkish (1) have an almost identical thematic structure, (2) treat both unmarked and marked Themes similarly, (3) have multiple types of Themes beside simple ones, (4) treat the elements of a multiple Theme similarly, and (5) have a MOOD-free THEME system. These findings show that both languages, which are genealogically different, have a similar THEME system and specifically the three subsystems of THEME MRKEDNESS, THEME SELECTION, and THEME TYPE. This result is consistent with ‘axial principle of congruence’. According to this principle, languages tend to be more congruent with one another in terms of paradigmatic axis/system than in terms of syntagmatic axis/structure.
         In the end, it is suggested that the typological behaviors of the THEME system of other languages spoken in Iran be identified and introduced in the aforementioned framework.

In line with Matthiessen’s claim mentioned above, the present paper has attempted to describe ʿmaterial clauses҆ in Persian within the system of PROCESS TYPE. This research has been conducted in terms of the following typological parameters concerning material clauses: (1) the number of participants involved in a material process clause (2) strategies for bringing in extra participants (3) the nature of Actor, (4) case marking, and (5) strategies for construing the transfer of possession and dispossession.
         Studying typological behaviors of Persian ʿmaterial clauses҆ in the framework of Matthiessen (2004)’s typological generalizations shows that in Persian (1) as in English, beside the two inherent participants of Actor and Goal, other participants, i.e. Recipient/Client, Initiator, Scope, and Attribute, are involved in the realization of the material process, (2) as in English but unlike languages such as German and Japanese, the inherent participant of Actor is widespread, (3) each of the above-mentioned extra participants is somehow added to a material clause. For instance, the Initiator is added to a material clause via causativization, (4) as in German, the case marking of material participants is fairly straightforward, and (5) as in English, the transfer of possession is construed differently from the dispossession. These results indicate that all Matthiessen (2004)’s generalizations concerning material clauses can be utilized in the description of Persian material clauses.
 In the end, it is suggested that the typological behaviors of the material clauses of other languages spoken in Iran be identified and introduced in the aforementioned framework.

Aim: Ethno-botanical knowledge is widespread and important among tribesmen. However, this knowledge is based on experimental findings rather than on a scientific basis. Apart from this, there is a risk that this ethnobotanical knowledge may disappear and be neglected. One of the endemic plants in Iran is Morina persica L., known in ethnoveterinary and ethnobotany. In this study, the chemical compounds of Morina persica L., an endemic ethnoveterinary plant, were investigated for the first time in Iran using GC/MS.
Materials & Methods: The collection of all M.persica aerial parts was conducted during the flowering stage. The extraction of essential oils was performed by a hydro-distillation method using a Clevenger device. Then, the gas chromatography-mass spectrometer device was employed to determine and analyze the essential oils composition. Kovats retention indices (KI=RI) were used to confirm the identification by the mass spectra

Integrated application of compatible methods is the most reliable strategy for sustainable management of phytophagous pests in different agroecosystems. In the current study, parasitism parameters of Trichogramma brassicae Bezdenko were determined on eggs of Tuta absoluta (Meyrick) reared on a susceptible "Infinity" and a resistant "Goldy" tomato cultivar. All experiments were carried out under laboratory conditions at 25 ± 1 ^°C, 65 ± 5% RH, and a photoperiod of 16:8 (L:D) h. Our results showed that the maximum number of parasitized hosts per parasitoid was 25.94 and 23 eggs in "Goldy" and "Infinity" cultivars, respectively. The cultivars tested had no significant effects on the net parasitism rate (C₀), and the values of this parameter were 7.87 and 6.67 hosts on the mentioned cultivars, respectively. Similarly, the cultivar impact on the finite (ω ) and stable parasitism rates (ψ ) of T. brassicae was not significant. The parasitoid needed approximately one egg host to produce an egg on both cultivars for the simple reason that this parasitoid nearly always lays one egg in each host. In other words, the transformation rate (Q_p) of the parasitoid on the "Goldy" did not differ from that estimated on the "Infinity". Our findings revealed that the resistant tomato cultivar, "Goldy", did not compromise T. brassicae-based biocontrol of T. absoluta. Therefore, these two control procedures could be combined for the integrated management of this pest.

Design of a suitable Control Strategy for operating a hybrid propulsion system in different types of roads and driving cycles is one of the most challenging subjects in hybrid vehicle research areas. Intelligent Control Strategies have been designed to meet the above requirement. The control signals in an intelligent control strategy of the hybrid vehicles are generated according to the driving cycle type. This is done by using a driving cycle identification unit. In this paper, design of a fuzzy based driving cycle identifier has been presented. The main idea in this unit is that any arbitrary driving cycle is similar to a group of standard driving cycles according to some degrees of similarity. As a result, the control strategy of the hybrid powertrain in the arbitrary driving cycle is affected by the optimized control strategy of the standard diving cycle based on the degree of similarity. Here, the subset of sufficient features is determined by using the floating search method as a useful feature selection algorithm. Also, the fuzzy clustering method is used to generate the values of similarity degrees to each standard driving cycle. Finally, the performance of the fuzzy driving cycle identification unit is assessed.

in the era of information, data which are worthwhile asset of human, organizations and enterprises have become such sophisticated that the conventional approaches and methods are not usable anymore, or not efficient at least. Such complexity which is known as the Big Data problem is the affordable extraction of value from big data sets that we are encountered in many recent applications e.g., e-business, scientific research, monitoring, search engines, social networking, etc.. Big Data complexities are instantiated by three major dimensions, high Volume, high Variety, and high Velocity (a.k.a. 3Vs). The first and most essential step in data management (also for Big Data management) is designing and employing a proper data model, as the footstone of the other data management activities such as R&D of DB languages, DBMSs, tools, methods, algorithms, etc.. In this paper, a proper data model for Big Data is designed and proposed in which the properties required for Big Data problem (i.e., to be integrated, complete, scalable, flexible, compatible, and efficient) are considered. As a data model, data representation is designed and implicit integrity constraints are presented for the proposed HNG (Hyper Nested Graph) data model. Experimental evaluation results show that the proposed data model outperforms other currently used data models such as the document-based, graph document-based, and graph-based data models in terms of response time.

Dry bubble disease is one of the most important serious diseases of the cultivated white button mushroom (Agaricus bisporus (Lange) Imbach). It is a cosmopolitan disease having a worldwide distribution. Ten isolates of Lecanicillium fungicola var. fungicola (Preuss) Zare and Gams were collected from mushroom farms. Sensitivity of the isolates to benomyl, carbendazim, carbendazim+iprodione and prochloraz manganese were studied. All the isolates were resistant to benomyl(ED50= 415.45-748.12 mg L^-1), carbendazim (ED₅₀= 1123.87-1879.59 mg L^-1) and iprodione+carbendazim (ED₅₀= 415.45-748.12 mg L^-1). However, most of the isolates were sensitive to prochloraz manganese (ED₅₀=1.62–12.58 mg L^-1). As the primary source of the pathogen inoculum is casing soil and insects, stringent environmental hygiene of the mushroom houses will play a very important role in preventing and controlling the disease.

Applications of hollow spherical particles in industry and in thermal spraying process have been developed in recent years. Despite dense droplets, in hollow droplets, the volume changes of the gas play an important role in the dynamics of impact and the shape of the formed splats. In plasma thermal spraying, impact velocities of particles to the surface is in the range of 50 m/s-300 m/s, therefore, changes in pressure and volume of the trapped gas, is important. In this research, impact of hollow droplet on a flat surface and its solidification has been simulated. Volume of fluid model for compressible flows at real thermal spraying condition is used while the impact velocities in the range of 50 m/s-300 is considered. In a few moments after the impact of droplet on the surface, a pressure wave is formed in the air. This wave, increase the vorticity in vicinity of interface of two fluid, which has a great effect on shaping the formed splats. Simulations showed that shape of formed splats vary with velocities in the range of 50 m/s-300 m/s. In higher velocities, the surface of the formed splat is more porous.

In this research, the impact of a completely molten hollow droplet and a semi-molten hollow droplet on a surface is simulated numerically. At first, the production process of hollow particles from the agglomerated particles is addressed analytically. By this model, one can predict the particle diameter, solid core diameter and shell thicknesses of produced particle. The results of this section show that hollow particle may hardly develop at small initial porosity values (p=0.2). Then, the collected data from analytical model is used as input data for numerical simulation. In the numerical model, the central solid core was assumed to be a fluid with high viscosity. Due to high impact velocity, volume and density changes of the trapped gas inside droplet are important. Therefore the compressible form of governing equations is used. The results show that the hydrodynamic and solidification behavior of a completely molten droplet and a semi-molten droplet during impact process are different. In the semi-molten state, the central solid core prevents the formation of a counter jet. For this reason, a hollow semi-molten droplet is solidified faster than a completely molten hollow droplet. The overall time of solidification in the completely molten state is 35 μs and the corresponding time for semi-molten state, is 12 μs. Moreover the splat of a semi-molten hollow droplet is more continues compared with a completely molten droplet

Modified continuum models have been the essence of much attention in nanomechanics through their computational efficiency and the capability to produce accurate results which are comparable to the atomistic models ones. As the dimensions of a structure approach to the nanoscale, the classical continuum theory has not the capability to predict the behavior of nanostructures due to the size-dependent of their properties which is known as size-effects. In this work, the bending behavior of nanobeams with common sets of boundary conditions is investigated using state-space modeling on the basis of nonlocal beam theories. Both uniform load and point load are considered in this study. To this end, Eringen’s equations of nonlocal elasticity are incorporated into the classical beam theories namely as Euler-Bernoulli beam theory (EBT) and Timoshenko beam theory (TBT). The maximum deflection of nanobeams corresponding to each set of boundary conditions is obtained using state variables and matrix algebra. The results are presented for different geometric parameters, boundary conditions, and the values of nonlocal parameter to show the effects of each distinctly. It is found that the non-dimensional maximum deflection corresponding to all boundary conditions and both loading cases will be increased for higher values of nonlocal parameter which show this fact that with increasing the nonlocal parameter, the stiffness of nanobeam decreases.
