This article investigates the syntactic parameters of the agreement/case system in three northwest Iranian languages, including Tati, Talshi, and Vafsi. Baker (2008) shows that the close relationship between agreement and case that Chomsky (2000) formalized it as the Operation Agree is a parametric matter and in all languages, the agreement does not depend on the structural case of the noun phrase. In this regard, he considers the existence of two parameters:  parameter (1) Direction of agreement parameter (DAP) which is based on the c-commanding condition and The Case Dependency of Agreement Parameter (CDAP) or Operation Agree and he believes that the Operation Agree or parameter (2) is only one the agreement parameters in universal grammar, not a principle ones. Also, in a language, all functional heads, if they agree with a noun phrase, are homogeneously subject to the fixed agreement parameter in that language. In this regard, we evaluate how the two parameters of Direction of agreement parameter (DAP) and The Case Dependency of Agreement Parameter (CDAP) are fixed in the functional head (T) and moreover we deal with other functional heads including determiners (D), prepositions (P) and auxiliary verbs (AUX). The results show that in these three Iranian languages, the functional head (T) is subject to the CDAP parameter, not the DAP one and the c-commanding condition is not necessary for agreement. Moreover, in par with the functional head (T), other functional heads are homogenously subject to CDAP. The method of data collection was the library method and interview.

Background: Osteoarthritis (OA) has been recognized, as the most common inflammatory disease in the world. Adipose Stem Cells (ASCs), as a new feasible source with high numbers of stem cells and proliferative capacity have been used for regenerative medicine. Based immunomodulatory and chondrogenic properties of ASCs, this study aimed to assess intra articular injection of ASC effect on improvement of osteoarthritis signs. Methods and Materials: Adipose tissue samples were obtained from subcutaneous of abdomen. ASCs were isolated and cultured for at least three passages in culture media containing autologous serum and expanded them to 15-20 × 10⁶ cell. The morphology and proliferative potency of ASCs were determined. Immuno phenotype characteristics of ASCs were analyzed by flow-cytometry. Then cell suspensions were injected into knee articular spaces. After 6 months the function of knee was assessed by WOMAC, KOOS, Lysholm and Lequesne indexes. Results: The results of this study showed that homogenous spindle-shape ASCs expanded rapidly with low doubling time. The low expression of CD14 and CD45 indicated that ASCs are non hematopoietic cells and expressed high percentages of CD44, CD105 and CD90. Our results showed that injected ASCs were effective in improvement of OA by scoring systems for evaluation of pain, joint movements and daily physical activities were significantly changed due to injection of stem cells. Osteoarthritis severity indexes means of WOMAC and Lequesne were decreased from 53 to 12.3 and 15.1 to 2.1 respectively. Also osteoarthritis improvement indexes Lysholm & KOOS means were significantly increased from 35 to 15.1 and 70 to 126.7 respectively. In six months follow up of intra articular injection of ASCs, we observed no local or systemic side effect. After ASCs injection, walking distance considerably increased. The flexion angle of knee improved by 20-30 degrees compares to before of treatment. Conclusion: Autologous ASCs injection could be resulted in increasing of knee function, alleviated of pain and quality of life improvement.

Water erosion causes a series of on-site as well as off-site damages and problems on natural ecosystem. These damages include soil and nutrient loss and finally loss of productivity which causes costs to the society. So, this study attempts to quantify the economic value of soil productivity conservation as one of the important functions of rangelands vegetation and its economic cost by productivity losses. The soil loss amounts were obtained from integrated Geographic Information System (GIS) and map of erosion vulnerable areas using RUSLE model. Supplementary data such as soil nutrients (NPK) valuated from the measurement plots of a portable rainfall simulator (E65). Field plots were constructed to measure soil nutrients and soil loss from different soil types with different resistance to erosion. Rainfall simulation was carried out in three sites on the basis of geology map and different resistance to erosion. Nine experimental unit plots (1*1 m) were used to correlate nutrient loss to sediment losses. Assuming that nutrient loss by erosion could be replaced by fertilizers, economic cost of major nutrients estimated by market prices of fertilizers. Results showed that mean annual soil loss using RUSLE was 27.44 t ha^-1 y^-1 ranging from 0.0 to 996.06 t ha^-1 y^-1. Also, 114.17 kg ha^-1 y^-1 of N, P, K elements were lost in 2010 due to soil erosion in the degraded rangelands which costs (738944 Rial) 71.5 US$ ha^-1y^-1. Total economic cost of soil nutrient loss in 94978.6 ha of the rangelands of Nour-rud watershed basin, was estimated 70×10^{^}9 Rial (6.8×10⁶ US$). The maximum annual cost of soil nutrient loss was estimated in the "TRujs" geological formation (1.23×10⁶ US$) consisting of "gray shale, silt, sandstone, conglomerate" and the least cost belonged to the "Jl1" geological formation (0.916*10⁶ US$) which consists of "thin gray dolomite limestone". In economic terms there was a direct relationship between soil nutrient loss and its economic cost.

The speech act of promise can be accompanied by two other speech acts: encouragement and pledge. Since, in this speech act, we have the concept of volunteer promise, and the speaker willingly makes a commitment to his/her addressee, according to George Austin's typology of speech acts, this speech act is considered to be an instance of commissive speech acts. Moreover, since the main features of performative verbs, i.e. “I, you, here and now”, are present in promises, promise is also regarded as a performative act. In political promises, given the objectives of the discourse as well as the personal traits of the speaker, Grice's maxims – quality, quantity, relevance and manner – may be violated. In a political promise, there may be as much brevity as there is repetition. Most of political promises serve merely as advertising goals and are not intended to be fulfilled. The maxim of relevance is generally heeded in political promises and the violation of this maxim before elections is fairly rare. Political activists usually make use of efficient and influential manner of speech in their election campaigns.

By emphasizing on the correspondences of linguistics and psychoanalysis, Julia Kristeva has presented new theories about the analysis of literary texts. “The Theory of Abjection”, which is derived of her post-structuralism researches, considers the author as a speaking subject who, through a poetic and semantic language, moves away from the ravages of his around. Kristeva has examined the applicative possibility of this theory in European literature. In this paper we focus on a contemporary Persian poem ("I am concerned for the garden" by Forough Farokhzad) for demonstrateing an application of the analytic approach of  the “Theory of Abjection”. Hence, we aim two principal purposes: firstly, we try to represent an exhaustive panorama of the analytic approach of the Theory of Abjection, and secondly,  we examine the possibility of creative interpretations of this poem According. Finally we try to examine the possibility of application of analytic approaches of this theory for the contemporary Persian poetry.

The verbal style of repentance is classified under the speech act of apology. To apologize to the highest authority in the religious hierarchy is called repentance. The purpose of this study is to identify the linguistic tools used to express repentance in both Persian and Russian. In this respect, we have attempted to understand the linguistic similarities and differences in repentance that lead to the diversity of this verbal style in the two languages. The research methodology is based on contrastive linguistics. The result shows that in both verbal environments, speakers use the single pronoun ‘you’ to address God. Moreover, the implication of imperative structure in the formulas of repentance is ‘request’ rather than ‘order’ and it includes begging and pleading with the addressee. In both languages, the singular imperative form is used to express repentance. Examples are Прости! (Forgive me) in Russian language, and dargozar (Forgive me) in Persian language. The characteristic of this verbal style in Persian is that some of these forms have been borrowed from Arabic: astaghfirullah and al’afv. In addition to the singular imperative form in Persian language, such borrowed forms – that are the morphological forms of the verb – as well as the phrasal form xodaya tobe tobe [=God, repentance, repentance] are used to express repentance. None of these grammatical structures are used in Russian language.

Due to the wide applications of gold nanoparticles, there have been great demands for their synthesis recently. Chemical methods produce pure and Non-dispersive nanoparticles, but these are quite expensive and potentially toxic to the environment. It has been suggested that the use of biological organisms and their components could be a suitable alternative for the production of nanoparticle in an eco-friendly manner (green synthesis). Using plant extracts for nanoparticle synthesis can be advantageous over other biological processes because it eliminates the elaborate process of maintaining cell cultures and can also be suitably scaled up for large-scale synthesis. In this study leaf extracts of Water cress, were used for green synthesis of gold nanoparticles. Gold nanoparticles were formed by treating an aqueous HAuCl4 solution by different amount of plant leaf extract as reducing agent at different temperatures. UV–visible spectroscopy was used for monitoring of the reaction progress. The synthesized gold nanoparticles were characterized with Dynamic light scattering (DLS) size analyzer, Transmission electron microscopy (TEM) and Fourier-transform infrared spectroscopy (FTIR). The results show that only a few minutes were required for the synthesis of gold nanoparticles at 60 °C and 80 °C by 1000 μl of plant extract, suggesting appropriate reaction rates in comparable to those of nanoparticle synthesis by chemical methods. TEM images showed that spherical nanoparticles (size, 10–50 nm) were obtained at higher temperatures and leaf broth concentrations. The analysis of FTIR bands show that the Polysaccharides and proteins are probably involved in the bio reduction and synthesis of nanoparticles.

Objectives: Tissue homeostasis is the result of strict regulatory mechanisms, which control self-renewal, differentiation, prevention of premature senescence and apoptosis of stem cells. Bmi-1, a Polycomb group repressor protein, represses genes that induce cellular senescence and cell death, and can contribute to cancer when improperly expressed. Material and methods: Bladder tumoral and nontumoral samples were collected from Labbafi-Nejad hospital. RNA was extracted from each sample, reverse transcribed and amplified by RT-PCR technique, using specific primers for Bmi-1 and β2-microglobolin, as an internal control. The production and distribution of Bmi-1 protein was also examined by western blotting and immunohistochemistry technique. Results: To clarify the role of Bmi-1 in bladder tumors, we examined the expression of Bmi-1 in tumoral and nontumoral samples. RT-PCR generated a 683 bp product, corresponding to the expected size of the Bmi-1 amplified region. The identity of the amplified fragment was then confirmed by direct DNA sequencing. The mean of expression of the Bmi-1 detected in tumoral tissues was significantly higher than the non-tumoral tissues and there is also a significant correlation between the mean of gene expression with stage of malignancy (p < 0.05). The expression of Bmi-1 at protein level was further confirmed by western blotting and immunohistochemistry. Conclusion: The tumor suppressor locus Cdkn2a (Ink4a/Arf locus) codes for two proteins, p16ink4a and p14arf. Ink4a and Arf are playing important roles in the retinoblastoma (pRB) and p53 pathways, respectively. Bmi-1 is a potent repressor of both pathways and hence elucidating its role in tumorigenisis is very important. Here, for the first time we are reporting the expression of Bmi-1 and its correlation with malignancy in bladder tumors.

Two chalcidoid parasitic wasps (Hym.: Chalcidoidea) of two lepidopterous pests on willow trees, Salix spp., were collected in Tehran and Alborz provinces, Iran. Ooencyrtus populicola Myartseva, 1995 (Hym.: Encyrtidae) and Colpoclypeus florus (Walker, 1938) (Hym.: Eulophidae) were reared on Ceruravinula (L., 1758) (Lep.: Notodontidae) and Nycteola asiatica (Krulikovsky, 1904) (Lep.: Nolidae), respectively. Ooencyrtus populicola is a parasitoid of egg and C. florus is an ectoparasitoid of larval stage. Ooencyrtus populicola is a new record for Iran, but C. florus was previously reported as a parasitoid of an unknown leaf-roller larva.

The authors in the present study attempt to investigate the speech act of compliments and its semantic boundary engagement with other speech acts of positive assessment of the speaker from the listener such as "approval", "praise", and "flattery ". The hypothesis of the present study is that the semantic boundary of speech acts containing positive assessment of the speaker depending on the verbal culture of the speakers of Russian and Iranian verbal environment is different,  and it is open to change in such a way that if a face expression in the Iranian cultural verbal environment is complimented, that expression may find the color and smell of flattery in the Russian verbal environment; in other words, an action with a positive assessment to an action with a negative assessment of the listener towards the speaker is interpreted as flattery. Furthermore, the compliment structures in each verbal culture have gender differences and characteristics (male and female). That is, the group of formulas used for men is inapplicable for women and vice versa.

Iranian literature and compliments are interpreted as politeness in international research. Goffman (1955, 1976), Brown and Levinson (1978, 1987), and Leech (1983) were the founders of these studies (Faika, 2016, p. 109). In other linguistic works written about Taarof, it has been interpreted as ‘compliment’ (Alavi & Zeinali, 2014, p. 139). Evidently, the lack of linguistic equality in other linguistic cultures indicates the absence of linguistic phenomena or their difference in the target linguistic culture. In such cases, ‘Taarof’ is an unequal Iranian cultural phenomenon in other cultures. It can be interpreted neither as compliment nor ceremony nor politeness. Taarof in other cultures should be considered as an untranslatable national cultural phenomenon and presented as the term ‘Taarof’ (Izadi, 2018).
In the verbal environment of Iranians, inappropriate compliments are considered a reprehensible practice. Hence, the Iranian proverb ‘reduce the compliments and increase the money’ referring to a situation where one is expected to pay a wage or do something, but instead, the audience witnesses ‘compliment’ and eloquence of the speaker in the concept of ‘Taarof’ and ‘praise’ of his action and performance.
Compliment in Russian verbal culture does not have an emotional and expressive tone and rhythm. Such an action is interpreted more as flattery by the Russian listener. However, the predominant feature of Iranian verbal culture as an Eastern culture is an exaggeration in the act of ‘compliment’ and the boundary of the compliment formation from flattery is clear, and the listener has no difficulty in distinguishing the two. However, in most cases, ‘praise’ is used as a tool to form ‘compliment’ in this linguistic culture, and therefore in Iranian verbal culture, the actions of ‘compliment’ are combined with ‘praise’. However, this does not mean an overlap between the two boundaries.
The following semantic and situational classifications can be considered in a compliment: 1) Gender: male and female; 2) personal and administrative; 3) Description of the external and internal qualities of the audience; 4) appropriate and inappropriate compliment; 5) compliment with an emotional tone.
In the Iranian verbal culture, using expressive speech acts represents politeness and even Taarof with the help of complimenting the audience. Using these speech acts, the speaker shows his attention to the audience, expresses his sincerity in ‘compliment’ and ‘praise’, while in ‘flattery’ there is no element of intimacy, and it is the result of hypocrisy. Depending on how ‘approval’ is used, it can indicate the role of a communication channel, i.e., using approval as a sign of listening carefully to the speaker; or answering his question from the point of view of correct logic. ‘Compliment’ and ‘approval’ can be on the horizontal or vertical axis of socialization, while ‘praise’ and ‘flattery’ can be seen only in the vertical axis of the age hierarchy or social administration. For ‘compliment’ speech act, we can somehow determine expressive and verbal tools in some verbal situations, namely, complementing the appearance, referring to the freshness and youth stability of the audience, meeting after a long time etc., while such a classification is impossible for flattery and praise.

A two-dimensional (2D) eXtended Finite Element Method (XFEM) simulation is presented for propagation of hydraulic fractures from wellbore that the minimum principal in-situ stress is in horizontal plane. One primary role of hydraulic fracturing is to provide a high conductivity pathway along which reservoir fluids can flow to the well. In this study, enriched element has been applied with a maximum principal stress damage criterion, for initiation and propagation of crack in Abaqus 6.12. The properties and input data for rock models were extracted experimentally from Ahwaz reservior- Bangestan wellbore specimens. The specifications of crack were studied by analyzing the rock model without any crack or flaw and under different condition, such as in-situ stresses, pore pressure and elastic modulus. The results show that the critical position of crack initiation is perpendicular to minimum principal in-situ stress and stress condition of borehole and by increasing the pore pressure to the rock models, the pressure of injection fluid decreases. The results show that the pressure of injection fluid decreases at initiation step to constant amplitude after crack propagation. These results are in close agreement with the theoretical data, so that our simple procedure is efficiency and flexible.

Abstract This paper focuses on layout modeling and optimization for a space control system. Majority of recent research works consider design components as constant elements over time. A new approach based on variable mass components is proposed in this paper for which the objective function is to minimize mass center variation (MCV) range over time. The proposed approach consists of Human-computer interaction (HCI) and Optimization methods to perform the layout. In the modeling phase, using defined inputs, all system components are determined. In the next step, mathematical model of achieved layout is defined. Mathematical model includes objective function, constraints, variables and parameters, play an important role in choosing appropriate optimization method. Based on mathematical model and design space, a gradient optimization method is selected. By applying this algorithm, optimum layout is proposed. Results of optimization and HCI design are compared. Comparison of the results shows that the optimization technique can significantly improve the results of the layout problem. At last, the results have analyzed and validated with similar research works. The results comparison show more efficiency and accuracy for the proposed method.

Industrial kilns and power plants with high consumption of fossil fuels play a significant role in the production of air pollutants. Nitrogen oxide is one of these pollutants. In the present work, effect of different geometries on NO reduction in stack of industrial kilns and power plants is investigated numerically based on a selective non catalytic reduction (SNCR) method. In SNCR method, the NO reacts with ammonia which is injected into the kiln stack at temperature range of about 1150-1350 K and nitrogen is formed. In this study, a cylindrical stack with 500 cm length and 5 cm diameter is chosen similar to Ostberg experimental work. Four geometries for ammonia injection with one, two, four nozzles and by a ring around the stack have been studied. Numerical simulation of NO reduction by SNCR method shows that injection with one nozzle has lower efficiency than other injection geometries. Also effect of gas stack length on NO reduction has been investigated. The results show that increasing of stack length, has significant effect on ammonia slip reduction phenomenon. To investigate effect of ammonia injection nozzle angle on SNCR efficiency, nozzle angles between -75 to 75 degree were analyzed. Results show that the efficiency of this phenomenon decreases by increasing absolute value of injection nozzle angle. Finally, effect of baffle presence in mainstream has been studied. It is observed that and the required time and length for reaction decrease due to better mixing.

Free hydroelastic coupled vibration analysis of frictionless liquids with a free surface in spherical tanks with a flexible bottom has been performed. The side wall has been considered to treate as a rigid body. The flexible bottom treats as a membrane at a certain distance bellow the center point, and the free surface is considered as a cross cutting at the top of the center point. The spherical coordinate system is adopted to derive the governing coupled equations, and finally a vibration analysis is carried out, using the traditional Galerkin's method, leading to closed-form solutions. Effects of various system parameters, i.e., membrane tension, liquid density, geometric parameters of the system such as the container radius, free surface distance discriminate parameter, and bottom distance discriminate parameter on the vibration behavior are investigated. The novelty of the present work is to obtain direct formulas for hydroelastic coupled vibration analysis of the mentioned system, which can be easily used in engineering design applications. Coupling between two mode numbers can be clearly seen in results, in other words, there is a coupling between vibration modes as interaction in spherical geometry.

This study was conducted to investigate the content of phenolic compound and radical scavenging capacity (IC₅₀) of chevil as a replacement for synthetic antioxidants. The extract of chevil leaves powder  was obtained by maceration (12 h)  and microwave (60 s) with ethanol or water  (100: 0, 75: 25 , 50:50) and the amount of  total phenolics and flavonoids was measured by spectrophotometry and antioxidant activity was measured by scavenging free radical 2,2-diphenyl -1- picryl hydrazine (DPPH). Data were analyzed by SPSS versiov 24 as well as variance analysis. The results showed that there was a significant difference between the extracts obtained by two used solvents ethanol and water (p<0.01). The extracts obtained by microwave showed the highest flavonoids content (0/75±0.008 mg Eq. Rutin/g dry sample) and the highest radical scavenging activity (1/04 ± 0/1) at ethanol to water ratio of 0:100 % as comared to maceration method. In contrast, the highest total phenol content (TPC) (3/665±0.09 mg Eq. gallic acid / g dry sample) was obtained by maceration at ethanol to water ratio of 0: 100%. For both methods, the rate of extraction was affected by solvents  ratio and water was more effective than ethanol.

Demand for the production and consumption of fresh meat has led to the use of various methods to improve the quality characteristics and increase its shelf life. In this study, stinging nettle extract (SNE) in combination with epsilon (ɛ-PL) were used for the production of fresh, functional, and extended shelf life of beef fillets. After drying of stinging nettle leaves under favorable conditions, aqueous extraction was performed at concentrations of 3, 6 and 9% (w/v) of leaves. A solution of ɛ-PL at 0.5% (w/v) concentration was prepared and mixed with 3, 6 and 9% of SNE. Beef fillets (4 treatments) were prepared in 2×2×2 sizes and treated for 1 h at 4 ° C with a ratio of 1 to 1 (meat fillets to SNE). Distillation water was used to treat the control. Finally, beef fillets were packed in polyethylene bags and quality properties were performed at days 1, 3, 6, 9 and 12. During storage, pH, phenolic compounds, redness value (a) and sensory scores decreased significantly (P < 0.05), and in contrast to lipid oxidation, total volatile nitrogen, lightness (L) and yellowness (b) increased significantly (P < 0.05). It was found that the treatment of beef fillets using SNE (6%) in combination with ɛ-PL (0.5%) resulted in a significant reduction (P < 0.05) in the amount of lipid oxidation and total volatile nitrogen compounds of about 50% compared to the control sample. The color and sensory characteristics of processed beef fillets showed that SNE in combination with ɛ-PL could increase the sensory scores of the samples. Based on the results, SNE had synergistic effects with ɛ-PL in reducing lipid oxidation and total volatile nitrogen compounds, therefore it could be used to produce fresh and functional beef.

Demands for high speed vessels are increasing due to various usages. Reducing the resistance to achieve high speeds is an important objective in design of high speed crafts. Creating longitudinal side tunnels in the hull causes resistance reduction. Designing the boat is not right only for reducing drag force; stability and maneuverability are also important factors. In this paper, high speed tunneled hull performance is evaluated considering numerical simulation of turning circle maneuver as a standard maneuver. The numerical approach is implemented due to high and acceptable accuracy compared with mathematical models and lower cost compared to experimental tests. Among the various techniques, modeling of maneuver of the boat was performed by considering mesh movement with boat and combination of sliding mesh and movement of domain as an effective method. Reducing computation time and increasing the accuracy of solution is of its advantages. Finite volume method and k-ω model is used respectively for discretization equations and simulation of turbulence. In free surface modeling, mixture model was preferred instead of free surface model. Solution methodology was validated using experimental results of a single-hull boat. Path of the boat in various tests was presented in the result section, considering the effect of angle of rudder, thrust and movement mode of the boat on the maneuver parameters. The results show enhancing maneuverability of the boat by approaching the planing mode so that by increasing the speed and closing to planing mode, tactical diameter is reduced up to 7.5% compared to the displacement mode.
