A bench scale aerobic sequencing batch reactor (SBR) was evaluated in terms of its potential to treat synthetic dairy wastewater. The 2-l plexiglass bioreactor was supplied with oxygen via a fine bubble air diffuser, fed with synthetic dairy wastewater under various operational conditions. To analyze the process, three significant independent variables — influent chemical oxygen demand (COD), mixed liquor volatile suspended solids (MLVSS), and aeration time — were assessed. Three dependent process and quality parameters (as process responses) were also evaluated: total COD removal efficiency, sludge volume index (SVI) and final pH. The experiments were based on a central composite design (CCD) and analyzed using response surface methodology (RSM). The treatment was limited to the following concentration regimes: COD (1000, 3000 and 5000 mg/l), MLVSS (3000, 5000 and 7000 mg/l) and aeration time (2, 10 and 18 h). Maximum COD removal efficiency (of 96.5%) was obtained for an influent with the following characteristics: CODin: 3000 mg/l, MLVSS 5000 mg/l, and aeration time of 18 h. The study demonstrated the capability of aerobic SBRs for high COD removal from dairy industrial wastewater. Easy operation, low cost, and minimal sludge bulking condition were some of advantages of the SBR system as an option for biological treatment of medium-strength industrial wastewater. The present study provides valuable information about relationships between quality and process parameters for different values of operating variables.

In this study, we investigated the effectiveness of both single and hybrid systems, incorporating UV photolysis and a Moving Bed Biofilm Reactor (MBBR), for treating synthetic wastewater contaminated with petroleum hydrocarbons. Petroleum hydrocarbons pose significant environmental threats due to their high toxicity, stability, accumulation potential, and resistance to biodegradation. In the hybrid system, the wastewater underwent chemical treatment first and then was introduced into the biological reactor. For the photolysis system, we explored the impacts of different concentrations and various radiation powers of UV-C lamps. Optimal conditions were determined to be a Chemical Oxygen Demand (COD) of 350 mg/L and a radiation power of 80 W. In the MBBR system, various concentrations were introduced into the reactor, achieving a maximum removal efficiency of 85% for an initial COD of 1000 mg/L over 72 hours with a 50% filling capacity. In the hybrid system, we achieved a remarkable hydrocarbon removal efficiency of 99% after 123 hours. Although the operational time of the hybrid system was relatively long, it demonstrated itself as a suitable treatment process compared to other conventional methods for removing these challenging, hard-to-biodegrade compounds.

An important subject in the field of linguistics is the impact of one thought system on the community of lingual symbols. The relationship between mind and language conventions has long been of interest to linguists. The importance of this relationship becomes more prominent in comparative approaches where, through comparative study and analysis of the main schemas of the ideas of several thinkers or artists, the researcher traces the consistent and common use of linguistic symbols. In the hermeneutic analysis of the works of Mowlana Jalal ad-Din Mohammad Rumi, the interpretation of symbols, analogy and codes governing his mind and language is a major research interest. One of the most important branches among these researches concerns the kinship of Mowlana’s language codes with other thinkers and artists. On the other hand, Nietzsche, as a transcendental thinker, tries to use a symbolic language in explaining his thinking system. Due to his familiarity with the culture and literature of the East and the essential sameness of some of his principles with Mowlana’s transcendental approaches about the existence, morality, art , etc., Nietzsche achieves a set of symbols common with Rumi, which forms a shared language between the two thinkers.

Is Meinongian dicopulation justified? This is the main problem in this paper and our hypothesis is that Meinongian dicopulaism is counterintuitive. This is despite the rich list of syntactic and semantic features that Meinongian advocates of the double copula strategy attribute to the Meinongian (internal/encoding) mode of predication in contrast with the ordinary mode of predication. That is what we demonstrate in this paper. We argue that neither of the requirement that Meinongian formulas (i.e. those containing the Meinongian mode of predication) must be monadic; nor that they resist lambda abstraction; nor that logical closure governs them; nor that they can be incomplete (or inconsistent) and nor that they are no way contingent, may succeed in discriminating Meinongian from ordinary predications. Nonetheless, dicopulaistic semantics support our intuitive understanding of abstract objects as sets of properties only whence they embrace the counterintuitive conception of multiple denotations; of either copulas or (abstract) objects. Meinongian dicopulaism does not work.

The information structure of a sentence is concerned with the formal expression of the referents and propositions in a given discourse. The formal expression of a referent is affected, among others, by such factors as the degree of mental identifiability of the referents, the pragmatic relation of referents in a proposition, etc. Based on the identifiability parameter proposed by Lambrecht (1994), the present study is intended to analyze the different lexico-grammatical codings of the mental referents and propositions in English and Persian. To do so, the first chapter of George Orwell's “Animal Farm” and its translation by Amir Amirshahi were analyzed based on the concepts of information structure theory. The findings revealed that the morphological coding in both English and Persian is affected by the degree of identifiability of the mental referents; in particular, identifiable referents were found to be represented by weak forms and unidentifiable referents by strong forms. In addition, English and Persian preferred morphological forms were found to be different. It was also found that identifiability parameter affects both the syntactic and prosodic patterns of the languages involved. The utterances with identifiable referents were mainly matched with subject position or were mainly coded as unaccented. In addition, it was found that, unlike morphological coding of both source language (English) and target language (Persian), identifiability parameter affected the prosodic and syntactic forms of both languages almost in the same way. Chi-square and Z test were used to show the significance of the statistics.

The aphid species, Cinara pini (Linnaeus, 1758) reported in our previous work as a new aphid on pinus trees for Iran, was described using the classic method and through analysis of COI gene sequence. In the next step, we addressed the efficiency of the entomopathogenic fungus, Lecanicillium longisporum (Zimm.) Zare and Gams strain LRC 190, on the aphid. The fungus was administered to the second instar nymphs and adults using topical application procedure. The results indicated that the entomopathogen caused 90% mortality in adults over seven days at a concentration of 10⁸ spores/ml, while the same control level was achieved for nymphs by 8 × 10⁷ spores/ml. The LC₅₀ values were obtained as 1.2 × 10⁶ and 6.9 × 10⁵ spores/ml for adults and nymphs, respectively. The present study suggests that the entomopathogenic fungus, L. longisporum could be considered as a potential candidate in biocontrol programs of C. pini. This is the first report on the pathogenicity of L. longisporum on C. pini.

With the advent of linguistic researches in the early seventies on the conditions of the women in language, an overwhelming turn came into the sociolinguistics. The most important rationale behind this attitude was the surge in Feminist movements in the modern times. Women authors strongly believe that masculine/male literature reinforces traditional sexual clichés and that in their works, portrays women as dependent and victim. They contend that the image depicted by men in their works of women is more frequently than not unrealistic. In other words, women/females in most of the literary works are considered as “others” to men/males and, henceforth, in male-dominated literature, the women question and the women experience are not dealt with. Quite on the contrary, the role assumed for women is what men ascribe to them and deem more suitable. This led to women arguing that, since they are endowed with special biological features and feminine experiences like sympathizing, cooperation, sensitivity and special power to observe, they are more likely to convey a special aspect of femininity to the reader, which is absent from male/masculine writing/écritude. Female writers in Iran could establish their place in writing fictional works and, hence, be widely received by the audience. This paper, via applying the Theory of Language and Social Semiotics, tries to delve into two novels: ‘Sovashon-by Simin Daneshvar-and ‘Adat mikonim'-by Zoya Pirzad. The methodology is descriptive-analytic. This paper substantiates the claim that women in different strata (syntactic, semantic and cognitive) of these two novels struggle to represent their identity in various ways.

The aim of this study, in the first step, was to recover the protein content in wastewater of fish meal factories using chitosan, chitosan nanoparticles and chitosan-aluminum sulphate composition. In the second step, the extracted protein was assessed for its  essential amino acids profile.  Also, the  reduced amount of proteins in the waste water was evaluated by measuring different parameters such as turbidity, pH, COD. Finally, chitosan nanoparticles characteristics were investigated using atomic force microscopy. Results showed that turbidity, COD and soluble protein significantly decreased upon  adding different concentrations of chitosan, nanoparticle of chitosan and chitosan-alum (p<0.05). The maximum protein recovery was related to chitosan-alum composition and chitosan nanoparticles with no significant difference between these two treatments. Evaluation of recovered protein in term of amino acids profiles showed that there were essential amino acids such as histidine, lysine, methionine and phenylalanine in protein of fish meal wastewater.

According to the usual definitions of ambiguity and amphiboly in rhetorics, the origin of amphiboly and ambiguity lies in polysemic words and position and intention of the speaker are the distinctive factors in the respect. Questioning this distinction, co-text is introduced as the criterion of differentiating amphiboly from ambiguity and as a result of such discussion a definition is formed which is the base of the arguments of this paper. The concept of multiple signification is considered equal to the application of polysemic words and the stability of semantic ambiguity resulting from multiple signification, is considered as the required condition of considering a case as amphiboly. In search of the possibility of amphiboly in theater de-contextualization of situational contexts, possibility of negation of various signifieds in any of semiotic systems in theater and impossibility of formation of various signifieds in the mind are considered to be the limiting factors.

The chloroplast gene matK, formerly known as ORF509, has been identified as one of the most rapidly evolving genes at the nucleotide and corresponding amino acid levels. This gene is located in the large single-copy region of the chloroplast genome, and placed between the 5’ and the 3’ exons of trnK (tRNA-lysine) within a group II intron. The matK RNA and protein levels are affected by light and developmental stages, suggesting functional roles for this putative maturase that affect in photosynthesis indirectly. The matK has been considered as one of the most useful genes for resolving phylogenetic and evolutionary relationships at a range of taxonomic levels, from closely related species to the generic, familial, and even supra-familial levels among land plants, especially Angiosperms. The matK as a DNA barcode for land plants showed high levels of discrimination among angiosperm species that can be used single or in combination with other genes.

The main purpose of this research is to develope a model for identification of organizational skepticism and its concepts. Grounded theory method applied for this research. Available non probable sampling method has been used and structural interviews have been performed with employees of private companies. Sampling continued until saturation point in answers has been reached (24 interviews). After using this method, including open and axial and selecting coding, causes and consequences of organizational skepticism have been identified. causes have been investigated in two fields. First, organizational management (management style and personal characteristics of manager and human resource management process and activities and Performance evaluation system) and Second, Organization related fields (organizational cynicism, organizational justice and organizational climate). Consequences of organizational skepticism also have been investigated in two fields of individual and organizational. Short-term effects of individual variables such as organizational indifference, motivational, lack of willingness to participate, job stress and burnout and long-term effects of individual variables such as low productivity of individual, corporate sabotage, poor quality of external engagement, life satisfaction and organizational frustration were classified. These consequences have also led to a long-term impact on organizational outcomes such as low productivity of the organization.

The present paper was an attempt to inquire into the morpho-syntactic features of light verb construction in Azeri-Turkish/Persian intra-sentential code-switching, employing the matrix language frame model. The analysis of data obtained from the interactions between bilingual teachers (n = 4) and students (n = 100) and from the conversation of 8 other bilingual teachers in a primary school revealed that Persian finite verbs do not participate in Azeri-Turkish morpho-syntactic frame simply because such verbs are [+ thematic role assigner] and carry more syntactic baggage. Persian preverbal elements, however, appeared to combine with Turkish light verbs showing more resistance to the syntactic frame of Azeri-Turkish in causative structures. Activation of embedded language preverbal element at predicate-argument level not only indicates the matrix language being far from the sole source for the grammatical shaping but also falsifies the independence of syntax from lexicon.

In the framework of stylistic discourse analysis, literature is a container to express ideas and concepts which are not only relevant to their creator, but also they are in connection with the context in which the text is produced. Yet, literature is the product of discourse where it is developed and all factors like environment, context, cultural issues and dominant ideology of the period in which the specific text is generated affect the growth and visibility of it. In Persian literature, Khorasani style is the product of discourse that its dominant face is full of philosophical thoughts and particularly rationality. This period is influenced by rational thoughts and intellectuality and NaserKhosro's poems, as one of well- known and effective poets and one of the most noticeable representatives of 5^th century literature, is regarded as a dominant sample of this conceptual indicators. Notable point in his poems is the influence of philosophical and religious thoughts, so that a large part of his odes court was devoted to this subject matter. In stylistic layered analysis of this poet's odes, dominant and cultural discourse of Khorasani period in which frequency of philosophical and logical subjects are notable shows specific style of the poet. In this study, based on stylistic layer analysis, in order to specify appearance of dominant- intellectual and cultural discourse of the period in the light of lexical and syntactic style, two layers of vocabulary and syntax of a number of his odes' court are analyzed.

According to a perspective, male and female copulatory organs have not more extreme morphologies. However, a skewed bias in males, -as well as the scanty taxonomic data on female genitalia, may explain why most evolutionary biologists failed to find acceptable evidence for the reproductive co-evolution in insects. A recent finding shows that the mechanical footing has a cooperative essence in the weevil genus Sitona. In this viewpoint, successful mating is achieved by the dynamic correspondence between the male endophallus and female genital lumen. The present work addresses some missing evidence in the genital traits of this taxon that may keep the hampered comprehensions under lock and key. The female bursal lumen in the studied species is provisioned with a pair of forklift-shaped structures (named the “codelocks”) that may provide for stabilizing the characteristic position of the male bio-syringe during copulation. This structure varies between the species based on the shape and direction of its paired levers, so that an elaborate algorithm possibly serves as the fuel of this device. However, in one of these, Sitona fairmairei (Allard, 1869), the levers perform a dual function in accordance to the lockback mechanism of the male copulatory organ. This species is also featured for having several campaniform mechano-receptors on the flanges of the male bio-syringe which are involved in the in-vivo navigation of this armature towards female spermathecal duct.

Colorectal cancer (CRC) is one of the most common cancers worldwide. Understanding of the tumor behavior, in a much closer look, at the molecular level, results in a more effective treatment and accurate prognosis of the disease. From among various genes altered in colorectal cancer K-ras is assumed to be of diagnostic and prognostic significance. K-ras mutations are believed to be a critical event in colorectal oncogenesis. Previous studies have demonstrated that 40% (20-50%) of CRCs harbor a mutant allele of K-ras oncogene. The mutations are limited to codons 12, 13, and 61 of the gene, with a great incidence at codon 12. The localization of mutations has given mutated K-ras an advantage of sensitive and simple detection over APC or p53 in which mutations are spread in their whole DNA sequence. To determine the incidence of K-ras mutations in CRC in Iran, compared with other countries, DNA was isolated from a random collection of 55 colorectal carcinoma samples, and codon 12 K-ras mutations were detected by RFLP. K-ras mutations in sporadic colorectal cancer in Iran are relatively frequent, with an incidence of 65%. This may be attributed to variation in methodology and to characteristics of the population studied such as differences in genetic background and variability in environmental factors and epidemiologic parameters such as diet, social lifestyle status, and other parameters that could be specific to the Iranian population. Correlation between the presence of codon 12 mutation and various clincopathological parameters was also investigated. A significant correlation was found with poor tumor differentiation of tumor samples. This places much emphasis on the role of promotion of differentiation as the most prominent effect of Ras.

In this paper, in order to detect the number of transmitting antenna in MIMO communication systems, it is proposed that the techniques such as AIC & MDL, which have been primarily designed so as to detect the number of Gaussian sources, are applied. Then a hypothesis testing based method for recognizing the type of modulation in MIMO communication systems with block orthogonal codes is suggested; in which in order to reduce the complexity of the traditional methods, simpler likelihood functions for testing hypotheses are applied. Furthermore, because in all modulation scheme detection methods, a proper estimation of channel gain (channel matrix) is required; in this paper, a new and efficient method based on SAGE iterative algorithm for estimation of channel matrix in MIMO communication system with space-time block codes is proposed. At the end of this paper, the performance and effectiveness of all proposed modules are separately and jointly analyzed by numerical simulations.

The egg-larval parasitoid, Ascogaster quadridentata Wesmael (Hym.: Braconidae) was stored for six months in the mature larvae of codling moth (CM), Cydia pomonella (L.) (Lep.: Tortricidae), under diapause conditions. Percentage of parasitoid adults (wasps) emerged from CM larvae reared under diapause conditions was about 86.6%. The biological characteristics (weight and longevity) were similar for both wasps that were treated under standard and diapause conditions. The data showed that percentage of parasitism for females emerged from standard conditions was 86.4%, while increased significantly to 97.8% for females emerged from diapause conditions. These findings may contribute to the mass rearing of A. quadridentata.
