     The growing global consumption of non-alcoholic drinks has brought attention to the characterization and quality control of popular beverages such as malt beverages. Organic acids remarkably impact on the microbial control, stability and organoleptic characteristics (flavor, color and aroma) of beverages. This study focuses on the determination of organic acids, including oxalic, citric, tartaric, malic, succinic, lactic, fumaric, acetic, propionic, and gallic acid, in 100 commercial malt beverages from different brands (five Iranian and five various imported brands) and flavored variants (classic, pomegranate, peach, tropical and lemon). In addition, the contents of total phenols, total flavonoids, ascorbic acid, and free amino acids were measured to assess the overall composition. Liquid chromatography (LC) was employed to develop a method for analyzing the organic acids, while spectrophotometric techniques were used for quantifying other bioactive compounds.  The results revealed significant variations in the organic acid profiles, with succinic acid being the most abundant, while tartaric acid was absent in all samples. For better data analysis, chemometrics technique (PCA method) was applied to classify achieved results. The results show that PCA can classify the malt drinks based on the additive values with a very high precision. In order to improve the quality control of malt beverages, it is recommended that some extra assessments like organic acids and free amino nitrogen determination tests would better to be considered at Iranian national standard.

The purpose of this study was to evaluate the performance of the Chess Federation of the Islamic Republic of Iran based on a 360-degree approach. The population consisted of three groups of managers, athletes and stakeholders (n = 1090). A researcher-made questionnaire was used for data collection that included three sections: demographic information and performance comparison of the previous period and a new period of chess federation management (including six dimensions of management and finance, evaluation, control and supervision, human resource management, championship and achievement of goal). Education, research and cultural and information technology) and factors influencing the development of this federation. Twelve experts confirmed the validity of the questionnaires, and their reliability was confirmed by Cronbach's alpha test (α = 0.88, α = 0.90). Data analysis was done using descriptive and inferential statistics Kolmogorov-Smirnov, paired t-test, independent t-test and Friedman test using SPSS 22 software. Finally, the impact of four factors on the progress of this federation was calculated and ranked. Based on the research findings, it can be concluded that the federation has improved in every six dimensions in the new management period compared to the previous one. Regarding factors influencing progress, management and finance had the highest and information technology and athletes had the least impact on federation progress. In general conclusion, it can be said that the correct management of variables affecting chess exercise can improve the performance of this sport.

Tyrosinase also known as polyphenol oxidase (PPO) is a copper-containing mono-oxygenase, which is responsible for melanization in animals and the enzymatic browning of fruits. It displays two distinct enzymatic activities: hydroxylation of monophenols to o-diphenols (monophenolase activity) and oxidation of the latter to o-quinones (diphenolase activity). The inhibition of tyrosinase is very important and encourages us to takes special attempts to search for new inhibitors. For the first time in the present study, the effects of 2-nitroaniline (a), 3-nitroaniline (b) and 4-nitroaniline (c) as well as their newly synthesized vanillin derivatives (2-nitrobenzenaminium 4-formil-2-metoxyphenolate (d), 3-nitrobenzenaminium 4-formil-2- metoxyphenolate (e) and 4-nitrobenzen aminium 4-formil-2-metoxyphenolate (f)) were studied on the oxidation of dopamine hydrochloride by mushroom tyrosinase. Among them, 4-nitroaniline (c) exhibited the strongest inhibitory effect, while acted as an activator. For these compounds, the IC50 follows the order of b> f= a> e> c. Compounds a, b and f were competitive while c and e were un-competitive inhibitors. The results indicated that the relative positioning of amino and nitro groups is important in the inhibition of the enzyme.

Livestock grazing and rangelands fire are important ecological disturbances influencing the vegetation and soil properties in rangelands ecosystem. This study was conducted to determine the effects of different burned treatments and distances from the water sources on some soil and vegetation properties of rangelands ecosystem. The experiment was conducted in Lashgar Dar Rangelands. Vegetation samplings were done based on the randomized systematic method across transects. Fifty randomized quadrats were sampled at each transect. One hundred soil samples per each transect were systematically taken by auger along each transect. The ANOVA and Duncan tests were employed for statistical analyses. The results indicated that the highest and the lowest above-ground biomass production (630 and 117 kg ha-1), Shannon-Wiener diversity index (2.37 and 1.07), soil TOC (18.34 and 6.66 g kg-1), soil gravimetric water content (16.4 and 6 %) and soil porosity (69.43 and 57.74%) values were found in the unburned rangelands with 2000 m distance from the water source and the one year post burned rangelands with 10 m distance from the water source, respectively. Whereas, the maximum and the minimum values of soil bulk density and soil EC were seen in the one year post burn with 10 m distance from the water source and the unburned rangelands with 2000 m distance from the water source, respectively. There were no relations between the soil pH change trends and the different burned treatments or distances from the water source.

Dictionaries are regarded as the basic criteria in language teaching and research; therefore, they are expected to be free from analytic fallacies. However, it seems that there are some inconsistencies in the definition of the morphological units in Persian dictionaries. In this article, echo reduplications (or Etbâ’) are studied in the text of LoghatNâme by Dehkhodâ. To this end, after defining the process of echo reduplications, all the entries which have been labeled to belong to this category, were extracted and analyzed according to the linguistic definitions available for echo reduplication. The analysis revealed that many of the entries with an echo reduplication label have not been treated correctly, and this error takes its roots from either referring to the echo contractions in other languages, or sticking to the traditional definitions of this issue.

This study attempts to evaluate one of the language use differences among women and men according to the Dominance Theory. The main purpose of the study is thus to investigate speech interruption as the participatory dominance factor based on the Dominance Theory in the Persian community and three affecting factors on interruption (direct statements, subject deviation and verbs and adverbs of uncertainty). Speech interruption and three affecting factors on interruption have been evaluated in the single and cross-sex societies. The data required were obtained from 40 two-stage interviews (10 men and 10 women students in the age range of 18-24 years). The men and women of this study in single and cross-sex societies, based on speech interruption factor, showed different linguistic behaviors and the linguistic representation of gender-based attitude in the Persian community was tangible. The relationship of each affecting factor on interruption with interruption was determined. The findings suggest that the framework provided by Dominance Theory in Persian community is inefficient.

One of the important issues in the study of grammar is the study of the structure and the functions of different sentences of a language, as well as describing the similarities and differences between them. This article aims to study the exclamative sentences of Persian according to a corpus and within a typological framework based on the study done by Zanuttini and Portner (2003). The article seeks answers to these questions: “What is the structure of exclamative sentences in Persian”?, “What are the semantic and pragmatic functions of such sentences”? “How these sentences can be differentiated from declarative and interrogative sentences”? and “What is the position of the negative markers in such sentences”? The results of this descriptive-analytic study showed that Persian Language has two types of exclamative sentences; declarative exclamatives and wh-exclamatives, which are different in terms of their semantic, pragmatic, syntactic and acoustic features.

Abstract:
Research subject: Leaching and recovery parameters controlling the releasing of selenium from Sar-Cheshmeh copper anode slimes are studied and determined.
Research approach: Copper anode slimes is produced during the production of cathodic copper at the bottom of electrolyte cells, which is composed of insoluble anode components in the electrolyte. The copper anode slimes are made up of those components of the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium, and other precious metals in the anodic copper. They are being extracted as a by-product in the copper production process. Due to the fact that the main source of selenium is sulfur deposits such as copper and nickel. Copper anodic slimes is currently the only source of selenium in the world. In this study, the extraction of selenium from anodic copper slimes has been feasible. To do this, acid leaching has been used. Copper anodic sludge is the raw material for the production of more than 90% of the world's selenium and is the main source of selenium production.[1-3]
Main result: In this paper, the effect of operational parameters such as acid concentration, temperature, process time and liquid to solid ratio on selenium recovery through copper slimes leaching was investigated. The optimum conditions of batch leaching For maximum selenium extraction from anodic copper slimes are attained at 3 mol L^-1 of HNO₃ concentration, 0.01 (W/V) solid to liquid ratio for 60 min contact time at 70 º­C. Under the optimized conditions, the selenium leaching efficiency was 99%. The thermodynamic data showed positive values of both ΔH and ΔS which indicates that the leaching process is indeed endothermic and random while the obtained negative values of ΔG show that selenium dissolution process is spontaneous in nature.

A total of ten isolates of fungi with Rhizoctonia-like mycelia were obtained from infected roots and stems of Pistachio Pistacia vera grown in a commercial nursery in Rafsanjan, Iran, during the autumn of 2011. The infected seedlings showed symptoms of chlorosis that later turned to necrosis. All of the isolates were identified as binucleate Rhizoctonia on the basis of hyphal characteristics and nuclear number. They were tested for detection of the anastomosis group, optimum growth temperature, rDNA-ITS region traits and pathogenicity on pistachio seedlings in vitro and in vivo. The analysis of hyphal anastomosis reaction was carried out with the tester isolates of binucleate Rhizoctonia AG-A, AG-Ba, AG-G and AG-F as well as multinucleate Rhizoctonia AG4 as already detected on pistachio seedlings. The optimum temperature for growth of binucleate Rhizoctonia sp.was 35 °C. In in vivo test, the symptoms of root rot were observed 30 days after inoculation and mortality happened two weeks thereafter. According to molecular characteristics and anastomosis test groups, all isolates showed greatest similarity to anastomosis group AG-F. This finding is the first report of anastomosis group F (AG-F) of binucleate Rhizoctonia, as causal agent of root and stem rot disease of pistachio in the world and Iran.

ntroduction
Since about a century ago, Iranians have been careful in facing the social developments of other nations and the implementation of the "development" paradigm in Iran and third world countries. And gradually their thinking has reached a degree of maturity to start an official effort to replace this paradigm.
A review of Iran's social history from 100 years ago until now, clearly indicates that Iranians have continuously observed the social developments of other nations and with the coming of the Pahlavi period, they witnessed profound spatial changes in Iran.
These developments took an organized form especially during the second Pahlavi period, and many programs were prepared in the field of administrative organizations, buying satellites, establishing a nuclear power plant, building big dams, creating a modern army, etc. The implementation of these programs in several decades was followed by a national review of what had happened. The general understanding of the society based on the emotional wisdom of what had happened can be summarized in a few basic points.
What has happened is pushing Iran towards a country with mass consumption and leading to dependence on foreigners.
The class gap and the population of the poor have increased drastically every day.
Nomadism and muralism are in danger of extinction
Environmental vulnerability has become a serious problem
Iran's cultural and historical identity has been exposed to destruction and its major change has manifested as a fundamental attack )Crossing identity, history and security(.
Theoretical foundations and objectives:
This article followed a comparative logic and mostly analyzed the differences between the development and progress paradigms. Also to run the progress paradigm it is tried to benefit from the executive structures of the development paradigm
Methodology
In order to achieve the goals of this research, at first, the bases and foundations of the development paradigm (Rusto in America), the land use paradigm (the French and the Germans) and the regional foresight paradigm (the European Union) in terms of epistemology are investigated, and according to the definition of paradigm according to Cohen, the semantic variables of each paradigm are indexed. The semantic variables defined for each paradigm were:

• The Hometown  of paradigm

• The Doctrine of paradigm
• The goals of paradigm
• The final destination of paradigm
• The executive subsystems of paradigm
• The ideological contexts of paradigm

After recognizing each of the semantic indicators of the paradigms, the recognition of these semantic indicators was discussed in the paradigm of progress. This work was done based on the latest version of the Paradigm of Progress document at the Iranian Islamic Pattern Center. In the next step, to compare these paradigms with each other, “Nich method” was used to calculate their spatial distance. The degree of difference of each in the field of Hometown, Doctrine, and Goals was determined. This comparison has followed “Jeanette's method” of analysis.
Findings:
Investigations showed that the four paradigms in spatial planning have sometimes fundamental differences in terms of Hometown, Doctrine, and Goals. These differences in their Hometowns, Doctrines, and Goals are different from what is discussed in the progress paradigm of Iranian society, and therefore, a review of the theoretical foundations of social and spatial evolution in Iran requires a serious revision.
Conclusions:
For the implementation of any paradigm, three systems (scientific-philosophical, governance and cultural) are necessary Which can generally be summarized in the following cases:
Borrowing the executive organization of the "development" paradigm is one of the valuable experiences, the use of which can reduce the fifty-year period of the progress paradigm to one or two decades.
Certainly, the implementation of the progress paradigm cannot be implemented without having three systems of "governance", "scientific" and "cultural", and this is the most important achievement of the development review and international experiences of several decades in the development paradigm.
In the field of philosophical and scientific system, although the combination of the field knowledge and the university is a suitable combination, but the change in the content is necessary both in the field of knowledge and in the university. Iranian scientists and researchers in both areas should define indicators that can continuously and intelligently evaluate the paradigm elements and the extent to which they have been achieved.
In the realm of culture, the tricks and techniques of the evangelists are very rich and only updating them and their form of presentation should be adapted and updated according to the taste of today's societies. In this matter, the main axes of the norms of the progress paradigm should be placed in the agenda of the cultural trustees and help in all processes that can transform these norms into social behavior at various scales.

In this article, the formal structure of the Persian relative clauses (restrictive and nonrestrictive) is examined. This study focuses on the possibility of extraposition of the relative clause to the right of its canonical position and it’s adjunction to TP or FocP. In general there are three approaches to extraposition in languages: rightward movement account, late merge analysis by which the relative clause should be late mereged with the constituents which they modify, leftward movement of the non-clausal part of an argument and stranding the clause. Based on some syntactic considerations in Persian such as having multiple clauses at the end of the sentence, movement of result clauses to the final position of the sentence, movement of relative clause with coordinate antecedent; relative clauses can moved to the right of the sentence and the extra posed element would be adjoined to TP or FocP and hence out the c-command domain of its trace.

Although syllable is not a meaningful unit of language, it has major functional roles in language. One of the most important functional roles of syllable is the formation and organization of language’s phonetic system. Any language has its specific syllable construct (patterns), and specific restrictions for the combination and use of sounds in the syllable level. In addition, various languages usually tend to keep their syllable rules; so, syllable patterns usually are not loaned by languages. Therefore, it can be said that part of differences in phonetic systems in various languages are caused by differences in their syllable structure. On the other hand, due to its main function (formation and organization of language’ phonetic system), syllable is directly associated with the learning of language’s phonetic system. The present article deals with comparison of the common syllable patterns in Russian and Persian languages. The results show that the patterns of the Russian syllable are more diverse than that of Persian. Most important differences that are often problematic for Iranian learners are the heavy consonant cluster in the onset of Russian words and syllables, as well as the frequency of multi-syllabic words in Russian language.

Politeness phenomenon is one of the subjects which have been observed by researchers of different domains , e.g. psychology, sociology and anthropology. Politeness has also been investigated in the area of pragmatics. One of the concepts following politeness is linguistic impoliteness. Different people such as Goffman (1967), Brown and Levinson (1987), Bousfield (2008), Culpeper (1996;2003;2011) and  Rudanko (1996) have worked on (im)politeness phenomenon. . In spite of the large amount of investigation on western culture, less research has been worked out on this notion in Persian. So, the aim of this study is investigating the function of this notion through describing it in  Sayyadan drama of  Ruye Sahneye Abi series written by Akbar Radi. The data was investigated through the five strategies proposed  by Jonathan Culpeper (1996; 2003) on linguistic impoliteness and the notions, e.g context, social norms and emotions, he added later in 2011. The most frequently  used strategy was positive impoliteness and the least used one was mock impoliteness. The synthetic ones were at the second level and negative impoliteness was at the fourth level. There was no withhold politeness among the‌ data. Finally, new cases were introduced.

The present paper is considered with the issue of verbal violence in the language of drama. In evaluation of verbal violence, Jeanette Malkin (2004) proposes six maxims, through which language is known as an arrogant element. The characters in dramatic texts (as in other literary texts) are created, developed, evolved and in some cases destroyed by language. In considerable number of modern plays, language acts as an antagonist who is to destruct and demolish the personality of the other(s) in the play with violence and aggression; so, the theoretical study of dramatic verbal violence as a component of dramatic discourse is considered indispensable to critical discourse analysis of dramatic texts and the study of power relations as reflected in the dialogues.; Focusing on the patterns of dramatic verbal violence introduced by Malkin, this study aims to discuss the dominant patterns of verbal violence in Hamlet With Season Salad, a play by Akbar Radi, and investigates the role of language in shaping, and destroying of human identities

Today, in historical and cultural studies, objects and images are also called sources of information as text- document. They are important not only to supply the information of written sources, but also to provide information enabling writers of historical texts who have not been able to express them. Examining these works and reading commonly used cultural themes can help better understand public opinion and lifestyle. The themes of magic and amulet are derived from the main doctrines and ways of thinking. The common cultural and religious ties that unite them are closely tied to the popular culture of the people. In the context of this study and in order to understand the influence of ideology and religion on the material culture of the Qajar period, the authors have tried to apply different themes to these works by studying the case of armbands to answer the following question: how do Islamic Shi'a notions fit into the apparent structure and patterns of Qajar armbands? Research methodology is descriptive – analytical. In this research, this issue has been addressed in two parts of the position of Iranian -Islamic culture and the formal and cultural annexes of amulets (narratives, codes and decipherments). The result of this study, while demonstrating the direct effect of Shia and Islamic beliefs on Qajar periodical armbands, showed the direct effect of popular beliefs on how these works are used and designed.

According to Sheridan and Gillett (2005), one fundamental form of inequality, being on the rise since 9/11, is religious discrimination. The main source of experiencing and being exposed to such inequalities and discriminations can be television which ‘is such an important source of information and entertainment that viewers cannot escape its gradual encroachment into their everyday lives’ (Laughey, 2007, p. 20). American TV series are so major and worldly-known entertaining media that many of them have millions of viewers around the world. So, it will be of great importance to make sure if they want to keep and even worsen this picture of Islam and Islamophobia. Therefore, this paper investigates the role of American TV series in promoting Islamophobia in public view. To do so, one has to analyze two main aspects of the TV shows which are the conversations and the picture frames. For analyzing the former, we have chosen Norman Fairclough’s (1992a, 1995, 2001) approach to Critical Discourse Analysis, and for the latter, Kress and van Leeuwen’s (2006) Grammar of Visual Design. American TV series, named Homeland (2011- still on air in 2017), broadcasted by Showtime® in the U.S has been the corpus of the present study. Its story that is mainly connected to the Middle East with lots of Muslim characters explains our choice. Consequently, the present study seeks to answer the following research questions: 1. Do the analyzed sequences of Homeland have Islamophobic elements based on Fairclough’s (1992a, 1995, 2001) CDA framework? 2. Do the analyzed sequences of Homeland have Islamophobic elements based on Kress and van Leeuwen’s (2006) Grammar of Visual Design? 3. Are there any combinations of visual and discursive elements to promote Islamophobia in the analyzed sequences of Homeland which can be analyzed by an integration of Fairclough’s (1992a, 1995, 2001) CDA framework and Kress and van Leeuwen’s (2006) Grammar of Visual Design?
Our work has led us to the conclusion that many cases in Homeland TV series, either discursive (based on Fairclough’s CDA framework (1992a, 1995, 2001)) or visual (based on Kress and van Leeuwen’s Grammar of Visual Design (2006)), were Islamophobic. Furthermore, there were cases in which both visual and discursive (audio) elements were used to promote Islamophobia. As a result, all of the research questions receive a positive answer. Moreover, it can be concluded that a combination of Fairclough’s (1992a, 1995, 2001) CDA framework and Kress and van Leeuwen’s Grammar of Visual Design (2006) can create a powerful approach in critical media analysis to expose the real policies of the media and power owners and decode the encrypted messages behind what is shown to the public. It is worth noting that analyzing a greater number of TV series could result in a higher generalization of our results.

Sonority determines the legal syllable structure of a language and triggers applying some phonological processes in order to retain the appropriate syllable pattern. All Turkic languages exhibit five different strategies/consonant cluster processes (metathesis, weakening, degemination, deletion and epenthesis) which are sonority-driven and arise through the interaction of markedness and faithfulness constraints. By considering a full range of data from Azeri and Turkish languages within the framework of optimality theoretic phonology we found that high ranking sonority constraints such as syllable contact law, sonority sequence principle, and sonority angle affect the clusters of loanwords and native words through different phonological processes. In fact these various phonological processes are used to improve syllable structure and save a segment from deletion. While in these languages words can end in two consonants, glide/liquid-nasal and glide-liquid sequences in spite of having rising sonority are not possible. Although coda sonorants may not be broken by a vowel epenthesis due to an OCP effect because /r/-obstruent and /n/-obstruent (ʣ) sequences are also not preferred in casual speech. In this paper, in the light of evidence from Turkic languages, issues like inserting and omitting of vowel within the rising sonority medial clusters, Prothesis and Anaptyxis in onset clusters, vowel epenthesis in rising and falling sonority final clusters, and consonant deletion in pre-consonantal coda position are considered within the framework of optimality theoretic phonology to show that the motivation for vowel insertion in word initial consonant clusters is to observe *Complex^ons, the epenthesis site (within the cluster or at the word-edge) is determined by the high ranking sonority constraints And also to show that the sonority advantage of a glide or a liquid over a nasal is insufficient to override Dep-Io. So what triggers the variable behavior of Turkish, Lebanese Arabic, Irish, Chaha, Catalan clusters is the Sonority Angel formed by the contours /CC/ and [CV]. Finally we observe that homorganic clusters are perceptually marked. That is a consonant which has few feature distinguishing it in place or manner from a preceding consonant is perceptually indistinct and is less suitable than a more contrastive consonant for maintaining lexical contrasts. Moreover we have to note that In Azeri the occurrence of coda-onset sequences across a syllable boundary subjects to the Syllable Contact Law (the optimal intervocalic consonant cluster is the one that terminates the first syllable with high sonority and starts the next syllable with low sonority). Thus Azeri applies some strategies to optimize the syllable contact. All clusters violating syllable contact are reordered, and broken up by epenthesis. Metathesis which can be explained in terms of phonological system rather than phonetical system is regular and productive in the language in question and links synchronic studies to diachronic ones.

In an experimental study, we compared the prosodic contours of two sets of complex sentences containing a relative clause. In one set, a relative clause was in unmark position (head-RL order), in the other, the relative clause was extraposed to the end of the sentence after the main verb. Two intonational parameters (pitch range and peak alignment) were examined on all components of main and subordinate clauses. The finding revealed that in-situ relative clause lacked an F₀ rise. while the extraposition  made the head noun a focal element showing a) a higher pitch than the same word in the unmarked condition; b) an earlier peak alignment with respect to segmental string as compared to the unmarked condition; c) the accentuation of post focal constituents. In addition, the post focal constituents are not necessarily deaccentuated by all speakers, some speakers tend to continue the rise and the preceding pitch accent up to the end of the main clause, and only de-accent the following extraposed relative clause.
