Narrative discourse and the arrangement of its components that reflect the narrative world provide the accessibility terms to the ideology and hidden values in the text; hence, it is important in the multilateral understanding of literary texts. Because the experiences and comprehension of the authors in interaction with the surrounding world do not have a similar effect on their perception, the narrative discourse changes from one narrative type to another.In “Biroon Az Gozashteh” by “Mehri Bahrami”various worlds coexist, there is no border between reality and fantasy, and the multiverse idea helps to understand the narrative discourse of the story. The main objective of this article is to show the selection of elements of the discourse through which the author constructs the story and the dominant ideology of the text, by investigating the narrative discourse of the novel. This research is text-oriented and has been done using text analyzing method. The main focus of this article is to investigate criteria such as the narration type’ various kinds of narratorsand their relation with the characters’ embodied experiences the narrator and characters and in line with it the formation of aesthetic and symbolic objects and hidden location in the narration. In this novel, the narrator’s subjective functions and her connection to other constructive elements of the text have an identity function and reflect the ideology of a text that tries to depict a woman who wants to pass behind her cultural-historical past and create a new self of herself.

Explaining the nature of metaphor and its role in language has always been a controversial topic in the fields of linguistics, philosophy of language, rhetoric, and so forth. In metaphor analysis, these fields often converge in an inseparable manner. Donald Davidson, a 20th-century philosopher, is one of the influential theorists in the Philosophy of Language and the Theory of Meaning. His views on the essence and role of metaphor in language bear significant similarities to the ideas of  al-Jurjani, a prominent 5th-century Hijri literary scholar. This research aims, through a descriptive-analytical method and a comparative approach, to examine the intersection points of Davidson’s and al-Jurjani’s theories, with one addressing metaphor from a philosophical and linguistic perspective and the other from a rhetorical standpoint. For this purpose, Davidson’s essay "What Metaphors Mean?" is used as the basis for reviewing his theories on metaphor. Al-Jurjani’s views are analyzed with a focus on "Dala'il al-I'jaz." This study yields results in three areas. The first, identifies similar aspects in the two theories, indicating that both theorists reject the idea of metaphor being merely a shortened simile. They also critique the notion of "metaphorical meaning," emphasizing that the meaning of a metaphor cannot be reproduced in any form other than the metaphorical one itself. The second area involves finding complementary aspects in the two theories, considering Davidson's philosophical stance and al-Jurjani's rhetorical position. The third area elaborates on the connection between al-Jurjani's direct views on metaphor and the ideas indirectly inferred from theory of Construction.

In corpus stylistics, computational tools are used to conduct qualitative and quantitative analyses of the electronic corpora of literary works, through which the stylistic components of the texts are identified. This study aimed to determine the stylistic features of the works of Simin Daneshvar and Ebrahim Golestan using a corpus-based approach. For this purpose, the works of these two writers were examined using corpus analysis tools, including keyword and concordance analysis in the AntConc software. After extracting the positive keywords in these works, each keyword was examined in its real context in the concordance menu, and a semantic classification was performed based on their semantic domains. The examination and comparison of the positive keywords showed that the semantic domains of "social behavior, work and profession, state and grammar" are common in the works of both writers. This commonality from a stylistic perspective can be related to similar social norms and behaviors, as well as the similar time and place of life and growth of the two writers. Golestan's works are writer-centered, while Daneshvar's works are reader-oriented. Daneshvar's story characters are much more numerous (14 names with a frequency of 504) compared to Golestan, who used only 3 names with a frequency of 107. In Golestan's stories, there is no reference to religion semantic domain, while in Daneshvar's stories, this domain is addressed. Daneshvar establishes a greater connection with the characters in her stories by mentioning specific individuals.

The effect of climate factors on the population changes and damage of peach twig borer (PTB), Anarsia lineatella Zeller., was studied during 2007-2017 in Saman orchards, Iran. Time series data of climate and pest population were subjected to the Mann-Kendall trend analysis. Seasonal flight of the pest was studied using pheromone traps from May to October. The percentage of infested twigs was calculated during May and September, while the percentage of infested fruits was determined twice a month from July to September. Results showed increasing trends in the mean temperature of annual, winter and autumn seasons (Kendall's statistics were 0.63, 0.49 and 0.42, respectively). Moreover, there were significant increasing trends in annual mean minimum, mean maximum and absolute minimum temperatures (0.53, 0.63 and 0.46, respectively). The number of annual and January frost days (-0.55 and -0.51, respectively) and mean relative humidity of Jun, July, August, September and October showed decreasing trend. PTB population and damage showed significant and increasing trends during the studied years. According to stepwise regression analysis the percentage of relative humidity, mean annual minimum temperature and mean annual temperature were the most statistically significant variables influencing the percentage of infested branches (r= 0.94, r²=0.88 , F (3,6)= 14.40, P= 0.004) and pest population (r= 0.98, r²=0.96, F (4, 5) = 3.18, P= 0.001). The pest population and damage will increase under studied climate change scenarios (A1F, A1T, A1B, A2, B1 and B2) in the future, which is more significant in A1F than others.

Aim and Introduction
Today, the environment is considered as one of the most important pillars of sustainable development, and the development of other economic and social sectors depends on its sustainability and proper functioning. Environmental pollution has become one of the main challenges of countries. Environmental health is currently one of the most critical concerns of people and officials round the world. Almost all managers and decision makers believe that this national wealth should be protected not only for the current generation but also for future generations, since the pollutants caused by industries are highly costly and detrimental to health.
Active industries are one of the main sources of environmental pollution. One of the necessary conditions for economic progress and the introduction of extensive structural changes in economic and technological fields is industrialization and industrial development. In the production process, using production inputs whose main source is the environment, in addition to desirable outputs such as consumer goods, undesirable outputs such as environmental pollutants are also produced. If the number of outputs is not controlled and disproportionate, the losses from undesirable outputs will be greater than the benefits of desirable products in such a way that damages to the environment would be irreparable and sustainable development less likely to be achieved.
One of the most important concerns related to industrialization is the effects and environmental consequences of industrial activities. Therefore, achieving the necessary solutions to control such consequences is vitally important. Minerals are essential for human survival, but their extraction and processing are not environmentally friendly practices which contribute to problems such as soil erosion, air and water pollution. On the other hand, mineral sector is one of the largest energy consumers which has active contribution to air pollution and global warming. The main purpose of this study is to investigate the economic effects of Gol Gohar mine in Sirjan. For this purpose, it is intended to determine the type and amount of pollutants released from this complex, and also to determine the amount of the green tax of the complex as a solution to reduce pollution and examine the social welfare resulting from reducing pollution.
Methodology
In this study, the economic effects of environmental pollutants of Gol Gohar Iron Mine in Sirjan (Southeastern Iran), is investigated using the input distance function model from 2001 to 2022. Through calculating the shadow price of pollutants, a criterion for determining the green tax is determined, and then the amount of social cost resulting from the emission of pollutants is calculated.
The shadow price of the undesirable output is the cost that the producer must bear if they plan to reduce the production of the undesirable output. In fact, it can be interpreted as the marginal cost of reducing pollution for each producer. Therefore, the shadow price of the desirable output is considered positive and equal to the market price of that output, but the shadow price of the undesirable output must be estimated to be less than zero.
Findings
The products of Gol Gohar Iron Ore Complex in Sirjan, include granulated iron ore, iron ore concentrate and pelletized in the production process. The most greenhouse gases and air pollutants are related to carbon dioxide (CO2), sulfur oxides (Sox), nitrogen oxides (Nox) and particulate matter (SPM). According to the obtained results, the average shadow price for air pollutants in Gol Gohar complex for CO2, Sox Nox, and SPM was calculated as 11.15, 3,074.5, 5,529.62, and 1,875.62 rials per kilogram respectively. Moreover, the average total social costs resulting from the production of Gol Gohar Sirjan Complex was calculated as 92,710 billion Rials according to the amount of pollution produced over the period.
Discussion and Conclusion
The estimation of environmental costs is actually an introduction to providing solutions for internalizing and reducing environmental costs, using the input distance function model and the shadow price of environmental pollutants in the industrial and mineral complex of Gol Gohar, Sirjan. The title of the largest producer of iron ore in the country was calculated, and the social cost resulting from the emission of pollutants was also evaluated. Finally, in this study, solutions and mechanisms for reducing environmental costs have been proposed.
Considering that the ability to absorb pollutants by the environment is limited, the shadow price of pollutants, which represents their real social cost, should be taken into consideration. The damages should also be determined based on the shadow price of the pollutants. In other words, the amounts of pollutant emission should be calculated and while taking into account the allowed limit of pollutant emission and shadow prices, based on a legal plan, the environmental costs should be reimbursed. Taking such measures would surely require more studies and capable executive management system

This study was conducted to evaluate the age-specific functional response of Psyllaephagus zdeneki Noyes & Fallahzadeh (Hymenoptera: Encyrtidae) at different nymph densities of olive psyllid, Euphyllura pakistanica Loginova (Hemiptera: Psyllidae). Due to parasitoid behaviour of feeding and parasitizing the host, both traits were separately explored on a daily functional response. Results of logistic regression revealed a type II functional response of the wasp independent of their ages. The handling time (T_h) and searching efficiency (a) were estimated using the Rogers equation. The highest searching efficiency for both parasitism and feeding was observed in the first five days of the adult age. The handling time for parasitism and host feeding increased with the age of female wasp. The highest searching efficiency and shortest handling time for host attacked (Parasitism and feeding) were gained in day 5 and day 2 and maximum parasitism and host feeding in days 2 and 3 of adult female age, respectively. We conclude that P. zdeneki demonstrated a reasonable performance as a potential biocontrol agent by feeding and parasitism of E. pakistanica which gained its maximum efficiency within 2 to 5 days of its life.

Aims: Adolescence is one the most precarious periods of life, concerning the drug abuse. The social cost of the drug abuse and injury among adolescents is extraordinary and requires intervention. The theory of planned behavior (TPB) is perhaps the most influential theory for prediction of social and health behaviors including drug abuse. This study aimed at designing and implementing a curriculum based on the TPB for preventing adolescents from drug abuse. Methods and Materials: This quasi-experimental study was conducted in Hamadan, west Iran. We recruited 140 male high school students from randomly selected schools: they were divided into experimental group, n = 70 and control group, n = 70. The experimental group received 20 hours educational program based on the TPB. The control group receives no intervention. Findings: Compared to the control group, experimental group have significantly elevated post test scores for attitude (19.07 vs. 15.28, p < .001), subjective norm (18.08 vs. 16.45, p < .001), perceived behavioral control (51.67 vs. 54.82, p < .001); and their intention to use drug significantly decreased(p = 0.082) Conclusions: The TPB-based educational program may be effective in prevention of substance abuse among adolescents.

Background: we aimed to evaluate the effect of body weight and Body Mass Index (BMI) on Bone Mineral Density (BMD) in healthy postmenopausal Iranian women. Material and Methods: Two hundred postmenopausal women (age between 51 and 69 years) who had presented to the nuclear medicine center at Shariati Hospital in Tehran, Iran between April 2012 and August 2013 were included in this cross sectional study. Of these 46 healthy women who met the study criteria constituted for evaluation. After recording weight and height of individuals, Body Mass Index (BMI) (kg/m2) was calculated as weight (kg) divided by height square (m²). Bone Mineral Density (BMD) in Femoral Neck (FN) and lumbar spine sites (L1-L4) were measured by dual-energy X-ray absorptiometry (DEXA). Results: We observed statistically significant negative correlation between BMD measurements at femoral neck and lumbar_1-4 spine with age and significant positive correlation with weight and BMI. Stepwise multiple linear regression analysis showed that only weight and age, after adjustments to BMI determined lumbar_1-4 spine BMD (R² = 23%) and femoral neck BMD (R² = 28.6%). Conclusions: These results suggest that the relationship between body weights and BMD is Stronger than the relationship between BMI and BMD. Therefore, in comparison with body mass index, body weight alone is a better predictor of bone mineral density.

In this research, closed-cell natural rubber foams were produced using a single-step compression molding. The effect of carbon black content on morphology, physical and mechanical properties of the foams were examined. Results showed that in this methodology, the foam density was independent of reinforcement percentage, which is a unique characteristic of single-step foams that contrasts with other previous observations. The study of curing behavior of foam compounds showed that the carbon black increasing from 0 to 30 phr increased the crosslink density (CLD) from 6.5 to 8.3*10^-5 mol/cm³, the cure rate from 16.1 to 23.2 (%/min) and the ultimate torque from 5.8 to 10.4 Nm, while, reduced curing time from 9.2 to 5.8 min. The scanning electron microscope (SEM) results showed that the reinforcement acted as a nucleation agent increasing the cell density from 8 N/cm³ to 140 N/cm³ and reducing the cell size from 579µm to 255µm. The increase of reinforcing content in the produced foams reduced the cells size and enhanced the properties of the rubber matrix. Accordingly, the modulus and hardness of the foams were increased by  0.8MPa and 40 shore A, respectively. Results of sound absorption and reflection showed that the rubber foam reflects the sound waves more than 90% and absorbs waves about 10%.

In the Magnetically Assisted Chemical Separation (MACS) process, tiny ferromagnetic particles coated with solvent extractant are used to selectively separate radionuclides and hazardous metals from aqueous waste streams. The contaminant-loaded particles are then recovered from the waste solutions using a magnetic field. In the present study, Cyanex272 or C272 (bis (2,4,4-trimethylpentyl) phosphinic acid) coated magnetic particles are being evaluated for the possible application in the extraction of Uranium (VI) from nuclear waste streams. The uptake behaviour of U(VI) from nitric acid solutions was investigated by batch studies.
Adsorption of uranium (VI) from aqueous solution onto adsorbent was investigated in a batch system. Adsorption isotherm and adsorption kinetic studies of uranium (VI) onto nanoparticles coated Cyanex272 were carried out in a batch system. The factors influencing uranium (VI) adsorption were investigated and described in detail, as a function of the parameters such as initial pH value, contact time, adsorbent mass, and initial uranium (VI) concentration. Magnetically Assisted Chemical Separation (MACS) process adsorbent showed best results for the fast adsorption of U (VI) from aqueous solution at aqueous phase acidity value of 0.5 molar. In addition, more than 80% of U (VI) was removed within the first 2 hours, and the time required to achieve the adsorption equilibrium was only 140 minutes. Langmuir and Frendlich adsorption models were used for the mathematical description of the adsorption equilibrium. Equilibrium data agreed very well with the Langmuir model, with a maximum adsorption capacity of 48 mg.g^-1. Adsorption kinetics data were tested using pseudo-first-order, pseudo-second-order and intra-particle diffusion models. Kinetic studies showed that the adsorption followed a pseudo-second-order kinetic model, indicating that the chemical adsorption was the rate-limiting step.

The essential oils of aerial parts of three medicinal plants Artemisia khorassanica Podl., Rosmarinus officinalis L. and Mentha longifolia L. were isolated by hydrodistillation and investigated for their toxicity and repellency against Tribolium confusum Jacquelin du Val. at 27 ± 1 ºC and 60 ± 5% RH in darkness. The mortality of the adults increased with concentration from 185 to 1111 μl/l air and with exposure time from 9 to 24 h. A concentration of 185 μl/l air and exposure time of 24 h was sufficient to obtain nearly 100% kill of the adults in all of the three essential oils tested. At the highest concentration (1111 μl/l air) R. officinalis oil caused 15% mortality for an exposure time of 6-h. whilst, the oil of A. khorassanica resulted in 1% mortality at the same exposure time. The oil of A. khorassanica at 1111 μl/l air caused 81% mortality for 12-h exposure time. No significant differences were observed between the lethal time (LT₅₀) values at essential oil concentrations of 741 and 1111 μl/l air. For 24-h exposure time, the LC₅₀ values of A. khorassanica, R. officinalis and M. longifolia essential oils were estimated to be 22.45, 22.14 and 39.96 μl/l air respectively. Based on LC₅₀ values, adults of T. confusum showed similar susceptibility to the A. khorassanica and R. officinalis oils, but M. longifolia oil proved to be less toxic. In contrast to their low fumigant properties, the essential oil of M. longifolia had significantly higher repellency to T. confusum adults than did the other two.

Medicinal plant powders have traditionally been used as grain protectants against stored-product insect pests. In this study, insecticidal activity of Carum copticum L. and Cuminum cyminum L. powders was assessed on adults of Sitophilus granarius L. and Tribolium confusum Jacquelin du Val. Experiments were carried out on wheat at 27 ± 1 ºCand 55 ± 5% r. h. The mortality increased with increasing concentration level and time exposed to each concentration. For S. granarius, 7 days and in case of T. confusum 14 days exposure time was sufficient to obtain considerable mortality. For example, 3500 mg/kg of C. copticum 7 days after treatment caused 80% mortality in S. granarius; while for T. confusum 29% mortality was achieved and increased to 100% after 14 days. Therefore, it can be concluded that adults of S. granarius were more susceptible than T. confusum to plant powders. Also, according to the findings, C. cyminum powder had more insecticidal efficacy than C. copticum on both insects’ species. For S. granarius, 950 and 2700 mg/kg powders of C. cyminum and C. copticum was enough to cause ca. 50% mortality after 5 days, respectively. In case for T. confusum, 3200 and 4400 mg/kg of the plant powders caused the same mortality after 7 days. Findings of the present study show that the plant powders could be applied for grain protection in small-scale storage facilities.

In this study, several data-driven techniques including system identification, adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and wavelet-artificial neural network (Wavelet-ANN) models were applied to model rainfall-runoff (RR) relationship. For this purpose, the daily stream flow time series of hydrometric station of Hajighoshan on Gorgan River and the daily rainfall time series belonging to five meteorological stations (Houtan, Maravehtapeh, Tamar, Cheshmehkhan and Tangrah climatologic stations) were used for period of 1983-2007. Root mean square error (RMSE) and correlation coefficient (r) statistics were employed to evaluate the performance of the ANN, ANFIS, ARX and ARMAX models for rainfall-runoff modeling. The results showed that ANFIS models outperformed the system identification, ANN and Wavelet-ANN models. ANFIS model in which preprocessed data using fuzzy interface system was used as input for ANN which could cope with non-linear nature of time series and performed better than others.

Aims: Drug abuse among college students continues as a major public-health concern. Theory-driven research is necessary to address and find causes. The current research investigates the utility of Theory of Planned Behavior (TPB) in designing and implementing a drug abuse educational prevention program among medical college students. Methods: This quasi-experimental study was conducted among 120 college students in two groups: experimental and control, who were randomly enrolled at the baseline survey. We used a questionnaire, which included three sections of background data (11 questions), knowledge about the side effects of drug abuse questionnaire (16 questions), and TPB-based questionnaire (20 questions). Educational planning was based on active learning with using group discussion, printed leaflet, and audio-visual CD. The participants were followed up after 2-month intervention. Data were analyzed by the SPSS software version 16 using appropriate statistical tests such as stepwise multiple logistic regressions and t-test. Findings: Almost 6.7% of the participants had a history of drug abuse. The three predictors of 1) attitude, 2) subjective norms, and 3) perceived behavioral control accounted for 48 % of the variation in the outcome measure of the intention to drug abuse. There was a significant improvement in average response for knowledge about the side effects of drug abuse and TPB variables among the students who were under intervention (P < 0.05). Conclusions: Designing intervention to reduce positive attitude and subjective norms toward drug abuse among college students could be useful to substance abuse prevention.

Hippodamia variegata is an efficient and most abundant predatory coccinellids in many countries. Understanding the ability of long-term low temperature survival in beneficial insects can be used to make better predictions about subsequent abundance and hence the biological control potential in the next spring and summer. So in this study, effects of long-term temperatures were investigated on mortality and supercooling point (SCP) of field collected (pre-diapausing) and overwintering aggregations of H. variegata adults. Unlike the pre-diapausing insects, aggregated coccinellids could easily survive at -3 and 0 °C for one month. One month acclimation at 10 °C caused more than 80% mortality in overwintering adults, indicating the higher temperatures were not appropriate for overwintering aggregated coccinellid. In December and January, when diapause was in its highest level, changing the habitat temperature did not affect SCP. Acclimation at 5 and 0 °C for one month decreased SCP of pre-diapausing adults, collected from aphid infested plants in October. Our study revealed that exposure to temperatures below 0 °C happened usually in natural condition for a long term period, may be necessary for overwintering of the coccinellid.

Plant extracts, like phytoecdysteroids, are currently studied because of the possibility of their use in plant protection. Phytoecdysteroids are insect steroid hormone analogues, and they are believed to deter invertebrates from plants, either by acting as antifeedants or by being toxic through hormonal disruption on ingestion. We describe here the effects of extract from Spinacia oleracea L. (Chenopodiaceae), a plant producing phytoecdysteroids, on the demographic parameters of Plutella xylostella L. (Lepidoptera: Plutellidae). Spinach is one of the very few crop plants which produce large amounts of phytoecdysteroids. Ecdysteroidal extracts of leaves from this plant were incorporated into food given to third instar larvae for two days. Then the larvae were reared on untreated leaves. The eggs from the emerging adults were picked up for demographic experiments. The rearing of the newly hatched larvae was continued individually on untreated leaves. All experiments were performed on 25 ± 1 ºC, 65 ± 5% RH and a photoperiod of 16:8 (L: D) hours in a growth chamber. Data analysis demonstrated that the fecundity of the females was strongly affected by ecdysteroidal extract. Values of intrinsic rate of increase and net reproduction rate decreased significantly as concentration of the extract increased. However, doubling time increased significantly as concentration of the extract increased. The present study demonstrated that the ecdysteroidal components of the spinach are effective on the demographic parameters of P. xylostella. Therefore, this extract may be potential protectants as botanical alternative agent.
