Aims: Colistin resistant Acinetobacter baumannii strains have become an important treat in nosocomial infection control. The reliable detection of these strains plays a critical role in treatment procures. The aim of this study was to evaluate the three different methods in detection of colistin resistant A. baumannii strains.
Materials & Methods: Eighty-three A. baumannii strains were isolated from hospitalized patients of a teaching hospital in Tehran during 1 year (2016-2017). All isolates were genetically confirmed by Polymerase Chain Reaction (PCR). The resistance to colistin was determined with disc diffusion, E-test, and micro broth dilution method.
Findings: According to the results of micro broth dilution as a gold standard, 43% of the isolates were resistant to colistin, while this percentage was 23% and 44% through E-test and disc diffusion methods, respectively. The positive and negative predictive value (PPV and NPV) of this method was 43% and 57%, respectively. The sensitivity and NPV index of E-test for the detection of colistin resistant strains was 76% and 68%.
Conclusion: Detection of colistin MIC by E-test strips has been commonly used in clinical laboratories to recognize the colistin susceptible strains. The NPV and sensitivity of E-test method demonstrated that this method has inefficacy to accurate determination of colistin susceptible strains. Thus, using standard protocol micro broth dilution with qualified materials should be stabilized and replaced instead of disc diffusion or even using E-test in clinical laboratories.

Abstract

One methods to critique translation is its assessment in order to determine the quality of the translation including the patterns presented in this type of evaluation and critique based on the Garces's evaluation model. This study intends to critique and evaluate the lexical selections of Hadad Adel, Moezzi, and Ansariyan's translation in verses 29 and 30 of the holy Qur'a according to the proposed Graces model at semantic-lexical level and seeks to determine extent to which Haddad Adel, Moezzi, and Ansarian's translations conform with the Garces's modelboth lexically and semantically. The study is rather a descripive-analytic one in terms of design. The findings indicate that the translations of the translators can be critiqued and evaluated in terms components of Garce 's model in a way that the translations of each translator can be regarded as an explanation (explanatory and lexical explanation), or as plenty of parallels, parallelism, syntactic expansions, and the transmission of ambiguity. Verification of the correspondence of translations with the semantic-lexical level of the Graces model shows that the Ansarian's translation in all of this level, except for the syntactic note, enjoys the highest level of correspondence with the semantic-lexical level, and secondly, the Hadad Adel's translation is used moderately at this level. In such a way that all of these levels are observed in their translations. Finally, the Moezzi's translation due to its literal translation enjoys the highest match except for the syntactic note among other cases and the lowest level of applicability and utilization of the Garces's model.

Abstract

This article studies the question of “meaning” in literary texts. First, I havepresented a definition for linguistic proposition. There is no proposition in language that does not have a linguistic definition; however,literature is replete with propositions without any acceptable referents. Under three circumstances the linguistic definition of a text is rendered null: (1) unconsciousness that is whenthe text indicates that the propositions were produced under an unconscious state; (2) anti-referentiality when the linguistic definition of a text is denied because itrefers to a referent that is inconsistent with our everyday experience; and (3) incongruity between the proposition and its producer, which happens when there is discrepancy between the linguistic definition of the propositions and our already-established assumptions about its producer. In conclusion, this article categorizes the propositions of a text in three categories: Propositions with acceptable linguistic definition that refers to a known referent; Propositions in which the secondary meaning is the speaker’s primary intended meaning and under this meaning they have external referents as well; Propositions that—no matter what generated their semantic ambiguity—are without any acceptable linguistic definition and that are not congruent with our known world and resist comprehension.

Abstract

Metalepsis, in its narratological sense, is a trope in which an unnatural relationship is built between different levels of narrative. The natural relationship between narrative levels is formed by the act of narrating; a character from one level becomes the narrator of another. The term “Metalepsis of topic and illustration” can be coined to name a similar trope. This trope has been used for centuries in Persian poetry. Every Image comprises a topic and an illustration. The topic is what is being talked about and the illustration is what the topic is compared to. When several images are present along together, two different levels are distinguishable: the level of the topic and the level of illustration. The natural relationship between these two levels is similarity and any other relationship will result in metalepsis. As in the narratological metalepsis, there is always a paradox in the metalepsis of topic and illustration. The effect of these two kinds of metalepsis is also similar and can be humorous, fantastic, or a mixture of the two.

Abstract

The purpose of this paper is to investigate those products which are produced by powder compaction procedure under the low rate impact loading by a drop hammer, both theretically and numerically. Experimental section includes checking the efficiency of density, bending strength and elasticity modulus of the product from grain size and different levels of energy. Two kinds of pure aluminum powder in three different size and also their combination with ceramic are used to obtain this. In the numerical section, dimension analysis method is applied in which non-dimensional models for density, bending strength, and elasticity modulus are presented in form of mathematical functions by means of experimental characteristics and data which are categorized to input and output. The purpose of determination of this model is to reach a reliable and satisfactory prediction for final properties of products subjected to impact loading condition. It is worth to note that singular value decomposition approach is used for calculation of linear coefficients vector which has been obtained by non-dimensional parameters.A comparison between these results and experimental data is done by mathematical functions in order to validate the results. The investigation of training and prediction data errors which has been based on root of mean of squares of error and coefficient of determination shows that the obtained results through mathematical functions have acceptable accuracy; hence utilization of the presented mathematical models for predicting the final properties of product subjected to impact loading is desirable.

Abstract

“Dash Akol” is one of the most important fictions in Persian literature. This short story is different from other fictions of Sadegh Hedayat. Sacrifice and “gheyrat” are important concepts in this fiction and this is questionable. The hypothesis of this article was that, unlike popular belief, “Dash Akol” is not entirely realistic but it`s a semi-Modernist short story because of central subjectivity of Akol. In other words, characterization in the second part of this story is Modernist. A Modern subject has three features and all of them are observable in the main character of “Dash Akol”: 1) Consciousness 2) Agency 3) Personhood. Akol have some secondary features too: 1) Overthinking 2) Attention to the unconsciousness 3) Solitude 4) Thinking about death. This short story is written in a period of contemporary Persian fiction that Modernist literature arose and this story has shown the evolution of contemporary Persian fiction.

Abstract

The purpose of this article is to investigate the relationship between quantity and quality of children in Iran. The quantity-quality models of fertility primarily assume that there is a substitution relationship between quantity and quality of children. The ambiguity in sign and final effect of newborns on the quality of existing children and the linearity or nonlinearity of such effect led us to investigate the relationship between quantity and quality of children in Iran. In this context, by using cross-section expenditure and income data of urban households in 2015, first we draw out a sample of 5624 children over 25 years of age in urban areas. Then, we investigate the relationship between quantity and quality by applying OLS method with Huber-White robust standard errors. The results show that there is significant, negative, and nonlinear relationship between family size and quality of children, but the size and sign of this relationship are not the same for all children, that is for first, second, and third births there is a complementary relationship between quantity and quality of children, and for births of more than three children there is a substitution link between quality and quantity of children. According to the results, we recommend that the population growth policies consider the size of families. If the policy of population growth focuses only on small families having no children or those having less than three children, population growth will not be detrimental to its quality and will improve the human capital of society.
