The two sides relationship between man and place has had a significant impact on the formation of various types of human culture.the relationship of place as a sign system with other cultural codes is discussed and investigated in cultural semiotics to determine the "umwelt" and " osemiosferes" of texts. A collection of poems Do Chenar by Hasan Roshan is one of the contemporary literary works in Persian language describing the history, culture and geography of North Khorasan, especially the city of Bojnord. In this collection of poems, the place element as a dynamic and fluid code is linked with other historical, social and cultural aspects of North Khorasan people which defines the osemiosferes of the text from the point of view of cultural semiotics.This article tries to analyze the semantic implications of the mentioned places in the Do Chanar based on the cultural semiotics approach of the place.The result of this study shows that the memory of ancient places (Spakho Temple, Etrak River), natural places (Faiz Abad Aqueduct, Palmis Spring), old streets and neighborhoods of the city (Sabze Maidan, Qaranga Dalan, Alang Och Agach, Shatrakhana) and modern places (cinema and cafe), religious places (Revolutionary Mosque, Imam Mosque) in Do Chanar are out of their function.

Extension field staff is the group of people who are responsible for managing activities related to agricultural information dissemination and farming community is the recipient or audience of that knowledge by implementing this knowledge on farm, farming community may enhance their farm productivity and uplift socio-economic situation. The Present study was based on primary data, collected from agricultural extension field staff (EFS) using interview schedule in cotton belt of Punjab province.  Three hundred and fifty-nine (359) extension field staff workers were selected from population of five hundred and forty (540) by using Cochran sampling technique. Moreover, Borich needs assessment model was implied to prioritize the training needs of EFS about climate adaptation. Study found that majority of the EFS seek trainings in specific areas regarding climate variability including; skills to use meteorological instrument, ability to comprehend early warning system, serving and mapping of climatic variability areas, management of ICT tools for weather forecasting, disaster management skills, and integrated soil management skills by acquiring these competencies they can effectively and efficiently work for minimizing the consequences of climate variability on cotton crop. There was significant positive correlation of 0.608 between specialization and possessed competencies regarding climate adaptation which shows that specialized extension staff possessed competencies regarding climate adaptation. On the basis of findings study suggests that the training needs of the extension field workers should be assessed regularly regarding various latest techniques and technologies. Training sessions regarding climate variability adaptation should be arranged for extension workers of cotton belt.

Background: Tuberculosis is one of the infectious diseases worldwide that has resurgence by the AIDS epidemic and led to the rise of drug-resistant tuberculosis patients. Thus, it seems essential to monitor the drug susceptibility in tuberculosis patients. The new High Resolution Melting (HRM) method is simple, rapid and inexpensive for detection of the mutations responsible for drug resistance in Mycobacterium tuberculosis isolates. In this study, we used HRM method to detect mutations in samples collected from tuberculosis patients. Materials and Methods: Three thousand sputum samples were collected from patients with suspected tuberculosis referred to Iran Remedial Center over a period of 2 years, out of which 2000 samples were found positive for M. Tuberculosis on direct smear. After extraction of genomic DNA from sputums, HRM method was used to detection of mutations in katG and inhA genes. Results: Our findings showed that 120 out of 2000 positive smear samples were resistant to isoniazid due to mutations in katG and inhA genes, out of which, 25 mutation was found in inhA gene  and 95 mutation in katG gene. Conclusion: The HRM method is quick, easy and affordable without need of culture and any post PCR process for diagnosing of drug resistance in tuberculosis clinical samples.

In recent years the growth rate of industry, science and technology has increased exceptionally and same relative changes in standards, practices and architecture operation has been more explicit. This suggests that nowadays architecture needs change and more dynamic than in the past and new buildings seem to be more varied, more flexible and adaptable to future possible changes, which needs architectural and structural solutions. In addition to being stable, one of the other mysteries of a creature is the ability of being responsible to many patterns which are expected in present and future. Although people are similar in humanity, they are unique in their aims, will and requirements. Therefore, in one place we encounter variety of requirements. In retrospect we can find out how man could solve their difficulties by the most basic movable structures and how he had designed mobile homes and flexible urban contexts to utilize in the future. This portable structure is also used in bridges, shelters, temporary and multipurpose spaces thus it has the ability to adapt to future needs. Although throughout history, man has lived in buildings which their function is fixed and unchangeable, but todays buildings function and users change rapidly and buildings should be constructed flexible and adaptable to the functional changes( for example climate changes), time change, social and cultural changes. What will be discussed in this article is examining, analysis and classification of structural systems of mobile and contemporary shelters. The purpose of these classifications is defining models that can be divided into various forms and production methods proposed for development and construction of systems available.

In this paper we propose and simulate a new Heterostructure MESFET, Called δ-doped LDD HMESFET. To improve carrier velocity in vicinity of the source in channel of GaAs MESFET, one can replace source with AlxGa 1-x As. By increasing Al content, discontinuity of hetero-interface could be increased. Therefore, the velocity increases in the low field. However, increasing Al mole fraction in excess of some value forces the current to reduce, due to DX centers. To avoid this reduction, we suggest taking the advantage of ?-doped the source-channel hetero-interface. This increase discontinuity of hetero-interface, which is equivalent to increasing Al content. In this paper, we simulate the proposed transistor structure and compare it with the one proposed in [1], ignoring DX centers. In this comparison, we show that the average electron velocity in both transistors is identical.

Entomopathogenic nematodes (EPNs) are commonly used as biological agents for control of insect pests. This study was carried out to identify EPNs, determine dominant and frequent species in Kurdistan province, Iran and characterize their symbiotic bacteria. Identification of EPNs was performed based on morphological and morphometrical characters and also rRNA-ITS gene sequences. Two EPNs, Heterorhabditis bacteriophora (Rhabditida: Heterorhabditidae) and Steinernema feltiae (Rhabditida: Steinernematidae) were identified. Out of totally 150 soil samples collected mainly from mid-southern parts of the province, 60% were positive for EPNs. Heterorhabditis bacteriphora showed the highest frequency in this region, remarkably 59.3% of soil samples contained this species. Incidences of H. bacteriphora in grasslands, woodlands and alfalfa fields were 57.3, 14.6 and 28.0 percent, respectively. Steinernema feltiae was found only in alfalfa fields with 0.66% frequency. Bacterial symbionts of H. bacteriophora and S. feltiae were also identified based on biochemical characters and recA gene sequencing. In this research, two species of Photorhabdus were isolated from H. bacteriophora namely P. luminescens subsp. kayaii and P. temperata subsp. thracensis. Xenorhabdus bovienii was identified from infective juveniles of S. feltiae.

Wisdom is a complex concept for which an accepted definition has not been presented yet. However, experts generally agree that wisdom consists of knowledge, insight, reflection, and the combination of an individual’s interests and others’ welfare. Due to the mysterious nature of wisdom, it has been the focus of research in different times, places and cultures. Since wisdom has a close relation with culture, and no clear definition of wisdom is available in Iranian culture, the present study analyzed and discussed wisdom and wisdom features in Shahnameh through the comparative study of characteristics of wisdom behavior in Zal based on Ardedt’s three-dimensional model. The population of this qualitative study included Ferdowsi’s Shahnameh. Through purposive sampling, Zal was selected for further analysis. Shahnameh’s content was analyzed through open coding, axial coding, and selective coding. Findings showed that wisdom features include religiosity and ethics, thinking/ awareness, perception of facts and lack of subjectivism and projection, empathy / affection and support/ service, communication and acquisition of cultural experiences and values. Furthermore, results showed that it is possible to express wisdom in five different dimensions, including spiritual, cognitive, reflective, emotional, social and cultural dimensions.

Pieris brassicae L. is one of the most important pests of Brassicaceae. The insecticidal effect of two entomopathogenic nematodes (EPNs), Heterorhabditis bacteriophora and Steinernema feltiae, was determined through their interaction with Beauveria bassiana and Bacillus thuringiensis subsp. kurstaki (Btk) against P. brassicae. In the interaction tests, the EPNs were applied at LC₅₀ level 0, 12 or 24h after treating the larvae with LC₁₀ or LC₂₅ of the B. bassiana or Btk. The interaction between the EPNs and B. bassiana was entirely different from the interaction of the EPNs and Btk. The interaction with B. bassiana was dependant on time intervals, while the interaction of the EPNs with Btk was almost additive or synergistic. An antagonistic effect was seen when the EPNs were applied immediately after the B. bassiana. However, the application of the EPNs 24h after their treatment with B. bassiana caused additive or synergistic effects. The results also showed the best mortality effect when the EPNs were used with Btk at 12 h and 24 h time intervals. Based on the results, a simultaneous use of the EPNs and B. bassiana is not recommended against P. brassica. However, the EPNs could be used simultaneously after Btk but it is better to allow a time interval to increase mortality.

Agrotis segetum (Denis & Schiffermüller) is an important polypahgous pest of sugar beet fields in many regions of world including Iran. Biorational pesticides are good and safe alternatives to the chemical insecticides which are compatible with goals of IPM programs. In this study, efficacy of three biorational pesticides, Azadirachtin (NeemAzal^®), Bt (Bactospeine^®) and Bt (Biolep^®), and a conventional chemical insecticide, deltamethrin (Decis^® EC), was studied on pest population and damages as well as carabid beetle population as its important predators in sugar beet field during two agricultural seasons (2015 and 2016). Sampling of the pest egg batches, larvae and the carabid beetles was carried out at 1 day before treatment (DBT) and 1, 3, 7 and 10 days after treatment (DAT). Finally, total yield and sugar content of sugar beet in the different treatments were evaluated for the two agricultural seasons. Results showed that NeemAzal was a significant oviposition deterrent for female moths of A. segetum. During both agricultural seasons, the highest and lowest larvicidal effects were observed in Decis and Bt (EC) treatments, respectively. Ten DAT, 40, 60, 13 and 73% reductions of pest population larvae were observed were observed in NeemAzal, Bt (WP), Bt (EC) and Decis treatments, respectively. Sugar beet yield in all treatments was significantly higher than control. Total yields in NeemAzal, Bt (WP), BT (EC) and Decis treatments were 17.5, 25.6, 12.9 and 43.7% more than control in 2015 and 8.7, 19.7, 4.8 and 37.1% respectively in 2016. But sugar content in the different treatments was not significantly different. Totally, the most adverse effects on carabid beetles were recorded in Decis^® treatment.

In this research, the effects of different levels ofWhite cheese (0-30%) and tri-sodium citrate (0-2%) on chemical and physical properties of Pizza processed cheese was investigated. Adding White cheese resulted in significant decrease (p ≤ 0.05) in pH, protein and significant increase in fat and salt content. Adding tri-sodium citrate induced the increase in pH and fat and decrease in moisture. The effect of mixture components on melting degree was significant (p ≤ 0.05). Free oil was affected by tri-sodium citrate ratio in the mixture. The oiling off was decreased by increasing melting salt, Length of stretch was decreased by increasing White cheese ratio in blend. Comparison of stretch length indicated a meaningful (p ≤ 0.001) correlation between "Fork test" and "Ring & Ball" method with Pearson coefficient of 0.906. The necessity of using tri-sodium citrate as melting salt for producing a homogenous cheese mass with the ability of exhibiting smooth slices without any fracture was approved in this study. Statistical analysis using mixture design showed that the optimum formula of Pizza Processed cheese was acheived by blending 90% base, 8.6% White cheese and 1.4% tri-sodium citrate. In addition to above,

Psychoanalysts and psychologists of different schools have analyzed fairy tales for psychoanalytic purposes. Bruno Bettelheim, a Freudian thinker, seeks to show how fairy tales, using imaginary faces, shape the process of healthy human development and make the process of development interesting and acceptable for the child. The Limped Deer tale helps children figuratively to learn how to manage the two conflicting feelings of love and hatred toward their parents and to preserve the image of the loving parents. In the story, when children leave home, it means that self-care and individualism require leaving home. Running away from the demon is a symbol of the child's conceptualization of the dangers of adolescence as imaginatively disturbing creatures. Siblings are symbols of the need to assimilate conflicting human and animal tendencies within themselves to achieve real development. The whale swallowing the sister represents an unreal death to reach a higher existence. "Replacement", "adjustment and modernization of deep psychological conflicts", "individuality and identity independence", "psychological extraversion", "personality integration", "mental, psychological and social order", "the cultivation of the imagination" are all the most important functions which are extracted from the Limped Deer. Therefore, it is concluded that fairy tales can address the fundamental problems of the child's maturity process figuratively and resolve them in an imaginative and indirect way.

One of the most important issues in the realm of education is assurance regarding the quality and effectiveness of teaching and teachers. In this regard, it is essential that models and instruments be developed in order to describe and assess them. It is one of the subjects creating a lot of interest in learners is English. Therefore, it is crucial to develop a model as well as a measuring instrument for describing quality of teachers and teaching in English. The present study was an attempt to develop such a model and instrument in a qualitative and a quantitative phase. In the qualitative phase, seven factors were identified as the underlying structure of teacher quality on which basis a 48-item questionnaire was developed. Then, in the quantitative phase, using Exploratory and Confirmatory factor Analyses, the reliability, and the validity of the model and the questionnaire were obtained. Based on the findings, both the model and the questionnaire are acceptable and valid and can be utilized.

  In this study, the effect of using palm and corn oils as a partial or whole Substitution of milk fat (0, 33, 50, 66, and 100%) on the physical and chemical properties of pizza processed cheese was investigated. No significant effect was found on the meltability and strechability of pizza cheese made by different oil sources, whereas, oiling off, iodine number as well as saponification number were significantly affected by the type of oil used in the formulation of pizza cheese (p<0.05). The high correlation (-0.717) between the oiling off and saponification number enable us to use the later as a diagnostic element to distinguish pizza cheeses made by vegetable oil sources as a replacement of milk fat which is illegal in some countries as well as Iran.

The problem of discovering the identity of anonymous authors has engaged humans' attention during the ages. In present times, with the revolution brought about by digital computing and electronic corpora, and also with the applications made available by stylometry research in forensic linguistics, systematic analysis of texts in different languages has expanded the understanding of researchers on the different aspects of linguistic styles.
In the present study, the possibility of authorship attribution based on idiolect has been investigated in Farsi. One of the linguistic elements that is claimed to be the seat for idiolect is function words. Function words have been the focus of attention in the authorship attribution research since it has been shown that they are processed unconsciously, have high frequency in texts, and remain independent of text topic. In this paper, the possibility of differentiating texts written by different authors has been studied using Farsi function words. The research questions were: 1) Are Farsi functions words capable of differentiating authors in Farsi prose? 2) Of monograms, bigrams, and trigrams, which one is the most efficient in differentiating author styles? 3) What is the minimum cut-off point for successful differentiation of author styles in Farsi?
First, a corpus of five Iranian scholars’ writings was compiled, normalized and divided into different sample texts. Then 20 most frequent words were extracted from different author samples and n-gram sequences (up to tri-grams) were analyzed using principal component analysis and cluster analysis in the Stylo package of R.
Findings showed that function words in Farsi were capable of differentiating authors’ writings with monogram words performing better than bi-gram and tri-grams in small size samples. Findings also indicated that under the experimental conditions used in this study, the minimum number of words for a text to be successfully attributed to an author is about 4000 words. This cut-off point is reached using 20 most frequent function words. It is concluded that different authors don't use function words in the same manner. In fact, while some high-frequency function words appear in the writings of all authors, they are given different priorities by different authors.

The aim of the present study was to investigate the students' learning styles and their influence on performance in various question types of IELTS examination and also in gaining higher band scores. In order to find answers to research questions, the researcher first used Kolb's questionnaire to recognize individual learning styles of candidates which were accordingly categorized into four classes as activists, theorists, pragmatists and reflectors. According to the results of the ANOVA, in listening comprehension section only some of the mean differences between groups were statistically significant in different question types. In note completion, multiple choice, and matching question types researchers faced a statistically significant difference. The results of the comparison between performances of the four groups in the IELTS reading test revealed that the mean score of the theorist group was higher in matching tasks and multiple choice questions and reflectors out-performed the others in task completion questions while activists had better performance in yes, no, not given tasks and pragmatics were better performers of short answer questions. So, researchers were on the safe side to say that variation due to belonging to different learning style groups causes variation of performance in different question types.

Aims: The patient decision-making process can become lengthy and overwhelming. Procrastination in visiting a hospital can have adverse effects on a patient's health. This study aimed to investigate how attitudinal ambivalence affects psychological discomfort and choice deferral in hospital selection. Additionally, the study explores the role of information novelty in reducing choice deferral and accelerating patient decision-making.
Instruments & Methods: This research employed a quantitative approach using a causal study to examine the relationships among variables. The purposive sampling method was used to obtain data based on certain criteria. Data were collected through a questionnaire distributed to patients. The research sample consisted of 385 respondents from private hospitals in Indonesia. Hayes PROCESS Macro software was used to investigate the relationships between variables.
Findings: The attitudinal ambivalence affected psychological discomfort (t=2.737; p=0.0001) and choice deferral (t=4.295; p=0.0001). The psychological discomfort influenced choice deferral (t=3.109; p=0.0001). The psychological discomfort had a mediation role in the effect of attitudinal ambivalence on choice deferral (t=10.678; p=0.0001). Information novelty reduced the effect of attitudinal ambivalence on psychological discomfort (t=2.653; p=0.003) and choice deferral (t=2.243; p=0.013). Finally, Information novelty weakened the effect of psychological discomfort on choice deferral (t=2.876; p=0.011).
Conclusion: Limited information can lead to information asymmetry, which can encourage attitudinal ambivalence and psychological discomfort. Providing comprehensive information to patients through digital media can help reduce anxiety and enhance their treatment experience in the hospital.
