Abstract
The present research investigates the conceptualization of the metaphors of “fear” in the Quran. Conceptual metaphors are an important discourse in cognitive linguistics. In this approach, metaphors are believed to be a cognitive phenomenon which manifests in language. This research aims to identify the initial spheres based on which fear has been conceptualized in the Quran and endeavors to attain the stance of the Quran on this emotion. To this end, a body of 607 verses containing the concept of fear was collected. In the next stage, 18 concepts were identified using cognitive analysis. The two schemas of force and movement as the initial spheres play a major role in the conceptualization of “fear” in the Quran. In conceptualization based on movement, behavioral and physiological actions of people facing external forces indicate their lack of control and defeat by external forces, with a virtual basis in most cases. In return, in conceptualizing fear based on the schema of force, the presence of a range of forces such as pressure, blocking, and redirection in facing external forces express the voluntary reaction of people in overcoming the external forces. Hence, in line with its guiding purposes, the Quran has missioned the prophets, in many cases as a divine command, to ask His audience to confront the non-divine external forces with the force arising from – the fear – of divine majesty.

Abstract
I aim to explore whether there are similarities and differences between the ethical virtues and vices in Nahj al-Balāghah in terms of cognitive-linguistics and based on the image schemas of Evans and Green's Model piety, perseverance, expenditure are the ethical teachings, described in Nahj al-Balāghah, chosen and analyzed based on image schemas. And the vices described in Nahj al-Balāghah are Secularism, greed, and jealousy. Studying the descriptive-analytical approach, I investigate and compare the virtues and vices discussed in sermons and short sayings of Nahj al-Balāghah in terms of cognitive semantics. Finally, the findings reveal that the general types of image schemas of Evans and Green’s model (schemas of Force, Balance, Unity/ Multiplcity, Existence, Identity, Locomotion, Containment, Space) have almost similar frequencies for both the virtues and vices. Among all, the schemas of force are the most repetitive in virtues and vices. And the balance is on the second level. The research finding is significant because it shows the similarity of the virtues and vices in using the different types of schemas in Nahj al-Balāghah. Their main difference lies in the way of using the subsets of the general concepts.

Abstract
The human experience is shaped through effective collaboration with forces. Johnson (1987) initially highlighted the significance of force schemas in conceptualizing events. Thus, this research seeks to explore this topic using a library-based approach, focusing on the force schemas presented in Johnson's cognitive semantics model and their application in Quranic verses related to infaq (almsgiving). In this inquiry, I seek to identify which force schemas are most commonly used in these verses and how they contribute to the understanding of the concept of infaq. In the analysis of the research data on the ethical concept of infaq in the Holy Quran, the concept of force image-schemas based on Johnson's model was used. The importance of the topic of infaq and the presence of force image-schemas in it were the reasons for choosing this ethical concept. In this regard, I examined the seven types of power in the context of infaq in the Holy Quran. The results showed that the force image-schema of obligation has the most frequency. In figurative language, the divine revelation's imperative and prohibitive commands, exert a pressure that functions as a force of compultion. After the force schema of compultion, the force schema of blockage has the highest frequency. In the Holy Quran, factors such as greed, hypocrisy, disbelief, and denial are introduced as obstacles to infaq. The force schema of "deviation from the path" does not exist in the interpretation of the verses of infaq.

Abstract
This study investigated the construct validity and measurement invariance of the Teacher Emotion Questionnaire to introduce a valid and reliable instrument for assessing English-as-a-foreign-language (EFL) teachers’ emotions inside the classroom. Second language (L2) teacher emotions have been largely neglected, despite the fact that Educational Psychology has long recognized and researched the role of teacher emotions in different aspects of teaching and learning. To bridge this gap, the current study had 208 Iranian EFL teachers in private language institutes fill out the Teacher Emotion Questionnaire (TEQ), which assessed six emotions teachers experience in their classroom, i.e., Joy, Pride, Love, Anger, Fatigue/Exhaustion, and Hopelessness. The preliminary analysis of the data showed that six items from the TEQ had a factor loading below the minimum recommended level of 0.3, meaning that they contributed to the total variance in the participants’ score less than expected. The collected data were then submitted to confirmatory factor analysis (CFA) for the purpose of construct validation and establishment of the factorial structure of the TEQ. The CFA results indicated that the hypothesized six-factor analysis had more favorable goodness-of-fit indices than both a one-factor structure and a two-factor structure (e.g., positive versus negative emotions). Multilevel CFA revealed that the tested six-factor structure of the TEQ was invariant across male and female EFL teachers. The implications for the use of TES in EFL teaching contexts are discussed, and some suggestions are proposed for further validation of the TEQ in language teaching contexts.

Abstract
The sugar beet moth, Scrobipalpa ocellatella (Boyd) (Lepidoptera: Gelechiidae) is one of the most serious threats to sugar beet cultivation worldwide causing economically significant yield loss. The life table parameters of S. ocellatella were determined on eight sugar beet cultivars (Dorothea, Ekbatan, Merak, Palma, Rozier, SBSI 007, Sharif and Shokoofa) under laboratory conditions at 25±1oC, 60±5% RH and 16:8 h (L:D) photoperiod. The longest (15.29 days) and shortest (7.61 days) female longevity was recorded on Shokoofa, and Merak cultivars, respectively. At the same time, Shokoofa and Merak cultivars had the highest and lowest total fecundity (85.26 eggs/female) and (32.39 eggs/female), respectively. The net reproductive rate (R0) varied from 9.31 eggs/individual to 39.44 eggs/individual on eight sugar beet cultivars; the lowest value was on Merak and the highest value was on Shokoofa. The highest intrinsic rate of increase (r) (0.102 d-1) and finite rate of increase (λ) (1.107 d-1) were on the Shokoofa cultivar. The results showed that all life table parameters of S. ocellatella were significantly different on the sugar beet cultivars tested. According to the conducted laboratory experiments, Merak was the most resistant cultivar to S. ocellatella compared with the other cultivars tested.

Abstract
Dracocephalum kotschyi Boiss. is a medicinal plant used in various industries due to its high health benefits, antioxidant activity, attractive flavor and aroma. Commercial yield and phytochemicals can be enhanced by cultivation management like suitable plant density. This study investigates the impact of planting density (50×40, 25×40, 12.5×40 cm caused to 5, 10, and 20 plants m-2) on the morpho-physiological traits, yield, trichomes, and phytochemicals profiles of D. kotschyi, based on a Randomized Complete Block Design (RCBD) in the Saravarsu region, Guilan province, Iran (2021-2022). The findings reveal a notable fourfold increase in various traits in 20 plants m-2 (12.5×40 cm). The highest values for parameters such as plant height (34.66 cm), branch number (14), branch length (9.34 cm), leaf number (138.33), leaf area index (105 mm2), fresh weights of leaves, and stems, as well as total fresh weight (105.1, 98.5, and 203.6 g m-2 respectively), dry weights of leaves, stems, total dry yield (26.1, 24.675, and 50.775 g m-2 respectively), chlorophyll a, b, total chlorophyll, and carotenoid content (1.038, 0.653, 1.691, and 0.898 mg g-1 FW, respectively), secretory trichomes density (14 mm-2), essential oil content and yield (0.633% and 0.322 g m-2, respectively), PAL activity (10.221 nmol g-1 FW min-1), antioxidant activity (82.85%), total phenol (1.253 mg g-1 DW), and total flavonoid (2.781 mg g-1 DW) were observed in 20 plants m-2. In conclusion, a planting density of 20 plants m-2 (with spacing 12.5×40 cm) is recommended for achieving optimal commercial yield, and phytochemical production of D. kotschyi in the Saravarsu region.

Abstract
The challenge of water scarcity poses a significant environmental challenge for the agricultural sector, jeopardizing the sustainable production of vital crops like wheat. Iranian provinces that produce wheat have varying water resources and climatic conditions. These differences have resulted in distinct economic benefits and environmental risks in wheat production among the provinces. In this study, the water footprint of wheat in each province was calculated from 2000 to 2020, and its environmental costs were deducted from the gross margin. Consequently, the social benefit was considered as the return of the wheat production portfolio in each province to manage the risk of sustainable production. Subsequently, the portfolio theory was employed through quadratic mathematical programming to minimize the social benefit-risk and determine the proportion of wheat cultivation in each province for optimal portfolio and sustainable production. The results showed that the provinces of Khuzestan (21.6%), Fars (17.1%), Hamedan (16.1%), Kurdestan (13.2%), Khorasan Razavi (11.4%), Golestan (11.3%), Qazvin (5%), and Kermanshah (4.3%) are in the optimal portfolio. In the optimal portfolio, a significant share of wheat production was related to the provinces with low risk in production (Khuzestan and Fars). The findings suggest that it is necessary to consider economic risks along with environmental risks to achieve sustainable production in the long run. As a result, the eastern and central provinces (Sistan and Baluchestan, South Khorasan, Semnan, Isfahan, Yazd) with the highest water footprint were removed from the optimal portfolio, and the western provinces with higher gross margin and lower water footprint were replaced with a larger share (Kermanshah, Hamedan, and Kurdistan).

Abstract
Urmia Lake and its surroundng wetlands have been severely affected by recent droughts (1998–2003) and a considerable decrease in inflow has affected lake ecosystem components. Integrated ecosystem-based management is a useful managing tool for the wise use and biodiversity conservation of wetlands. In the process of developing an integrated ecosystem-based management model for Urmia Lake, the identification of key stakeholders is of primary importance. In this research, stakeholder analysis is used as an effective tool for establishing collaborative management in the Urmia Lake catchment in terms of the following parameters and objectives: almost all stakeholders receive multiple benefits from Urmia Lake, either directly or indirectly; almost all stakeholders also cause impacts on the lake ecosystem, many of which result from activities that take place in areas located within in the Urmia catchment but far from the lake. In general, the stakeholders who receive the most benefits seem to cause the lowest impact (for example, Environmental groups), while those who receive fewer benefits may have larger impacts (for example, water resource managers). Recognizing that all stakeholders affect the lake in one way or another is an important concept that promotes the ethic that future management of the Lake should regarded as a shared responsibility between all stakeholders.

Abstract
Reproductive performance and life expectancy of the two-spotted spider mite (TSSM), Tetranychus urticae Koch were determined on seven eggplant cultivars (Isfahan, Dezful, Shend-Abad, Neishabour, Bandar-Abbas, Jahrom and Borazjan) at 25 ± 1°C, 60 ± 5% R.H. and a photoperiod of 16:8 (L:D) hours. The results revealed that the TSSM gross hatch rate varied from 59% on Bandar-Abbas to 83% on Dezful. The gross fecundity rate was 59.726, 31.430, 31.443, 14.461, 19.328, 16.035 and 20.560 eggs/female and the net fecundity rate was 25.804, 17.496, 15.139, 7.620, 5.931, 7.526 and 11.947 eggs/female on the above-mentioned cultivars, respectively. The highest and lowest value of the net fertility rate was 20.735 eggs/female on Isfahan and 3.495 eggs/female on Bandar-Abbas, respectively. Also, the gross fertility rate was the highest on Isfahan (47.994 eggs/female) and the lowest on Bandar-Abbas (11.390 eggs/female). The values of the mean eggs per day varied from 2.040 to 6.560 eggs/female, which was minimum on Neishabour and maximum on Isfahan. The life expectancy of one-day-old adults of the TSSM was estimated to be 7.550, 8.380, 5.820, 4.850, 5.440, 5.330 and 3.950 days on the above-mentioned cultivars, respectively. Comparison of the reproductive parameters of the TSSM on the examined cultivars revealed that Isfahan was the most susceptible cultivar and Neishabour was the most resistant cultivar to this pest. Using resistant host plants is one of the most important components of an integrated pest management program.

Abstract
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 (Th) 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.

Abstract
The historical and literary a common ground in Persian and Arabic Created Valuable Literary poems on various subjects. We can mention elegy that versified in the sadness of destruction of Baghdad by Saadi Shirazi and Shamsuddin Kofi. Reflecting the Mongol invasion of Islamic countries, including Baghdad caused profound grief and sorrow over the lives of Muslims. In this article we have tried to analyze the reflection of the tragedy in the poem of the two poets and we have mentioned by Comparative analysis to the Themes and content is written by the poet's and We have also explore the similarities and differences of the two poet elegy. The results of this study indicate that both the poet in several main themes have in common such as crying and grief, complained of oppression days tend to pre-Islamic Arabic language and literary style and Mention honors predecessors. Lastly Both poet said monody by Pure and simple Diction, yet full of sorrow and regret, in elegy of Baghdad and ”mostaasem”.

Abstract
Introduction: In the modern society, the floating population has daily travels between the place of residence and the place of work or education and travels through towns and villages every day at a given time. With the expansion of Tehran metropolis, floating population was introduced as one of the city's problems. The population of Tehran, during the day, is one or several million more than the population of the city at night. For the first time, a question was asked in the Population and Housing Census in 2007, and the place of work and education of individuals were asked. In the 2012 census, two separate questions, for the place of work and education, were designed to evaluate the floating population. Using the library resources and documentary research, the present descriptive-analytical study was conducted with the aim of investigating the effect of population flotation on the population gap at day and night in Tehran metropolis in the census performed in 2012.
Conclusion: In 2012, Tehran metropolis accounted for about 72% of the urban population of the province and one-fifth of the floating population of the country. A total of 78% come from other provinces to Tehran metropolis due to work and 22% come for eduacation and most of the floating population is a young population. The reason for going to Tehran is education for most of the young women and work for most of the men, which is affected by socio-cultural characteristics of the society. The most important reason for the daily flow of the population toward Tehran is the lower cost of living and the lack of employment and education facilities in dormitory cities, which shows the exacerbation of the inequality in the imbalanced development of Tehran metropolis with other parts of the country, including the surrounding satellite cities.

Abstract
Following years of contamination, rivers may experience significant levels of heavy metal pollution. Our research aims to pinpoint hazardous areas in these rivers. In our specific case, we focus on the floodplains of the Meuse River contaminated with zinc (Zn). Elevated zinc concentrations can lead to various health issues, including anemia, rashes, vomiting, and stomach cramping. However, due to limited sample data on zinc concentrations in the Meuse River, it becomes imperative to generate missing data in unidentified regions. This study employs universal Kriging in spatial data mining to investigate and predict unknown zinc pollutants. The semivariogram serves as a valuable tool for illustrating the variability pattern of zinc. To predict concentrations in unknown regions, the model captured is interpolated using the Kriging method. Employing regression with geographic weighting allows us to observe how stimulus-response relationships change spatially. Various semivariogram models, such as Matern, exponential, and linear, are utilized in our work. Additionally, we introduce Universal Kriging and geographically weighted regression. Experimental findings indicate that: (i) the Matern model, determined by calculating the minimum error sum of squares, is the most suitable theoretical semivariogram model; and (ii) the accuracy of predictions is visually demonstrated by projecting results onto a real map.

Abstract
The diamondback moth, Plutella xylostella (L.) is a serious and economically important pest of cruciferous crops worldwide. The nutritional indices of this pest on four host plants including two canola (SLM046 and RGS003) and two cabbage cultivars (Green-Cornet and Glob-Master) were determined under laboratory conditions (25 ± 0.5 °C, 65 ± 5% RH and 16: 8 L: D h). The highest relative consumption rate (RCR) and relative growth rate (RGR) were recorded on RGS003 (95.68 ± 14.52 mg/mg/day) and SLM046(0.382 ± 0.041 mg/mg/day), respectively. The efficiency of the conversion of ingested food (ECI) and efficiency of conversion of digested food (ECD) were significantly higher on SLM046 (2.298 ± 0.646 and 2.471 ± 0.719%, respectively). However, there was no significant difference among cultivars regarding approximate digestibility (AD) index. The highest feeding performance of the larvae of P. xylostella was found on SLM046. The nutritional indices are appropriate tools in host plant resistance evaluation and they also could provide profound understanding of the behavioral and physiological bases of insect-host plant interactions.

Abstract
The cotton bollworm, Helicoverpa armigera (Hübner), is a serious pest on a wide range of economic crops in many parts of the world. In this study, digestive proteolytic and amylolytic activities of H. armigera larvae (3rd to 5th instars) were evaluated on five main host plants including chickpea (cv Hashem), cowpea (cv Mashhad), soybean (cv 033), navybean (cv Dehghan), and corn (cv SC 704) at 25 ± 1 °C, relative humidity of 65 ± 5% and a photoperiod of 16: 8 (L: D) hours. The results indicated that the highest enzyme activity was in 5th instar. The highest general protease activity of 3rd, 4th and 5thinstar larvae was found on corn. The larvae fed on corn had the lowest trypsin activity. This leads to hyperproduction of chymotrypsin and elastase-like enzymes to compensate the inhibition of trypsin. The larvae of H. armigera reared on cowpea had the highest level of amylase activity, and the lowest activity was in the larvae fed on corn. The results revealed that among host plants tested, corn was more resistant (unsuitable) to H. armigera. Study on digestive proteolytic and amylolytic activities of H. armigera can be used in identifying the antidigestive or antifeedent compounds, which will help us to design appropriate management programs.

Abstract
Rosy apple aphid, Dysaphis plantaginea (Passerini), with worldwide distribution is an important pest of apple orchards. Host plant resistance is an essential component of integrated management of this insect pest. We investigated the resistance of seven apple cultivars, Malus domestica (Borkhausen), namely Granny Smith, Starkrimson, Golden Smoothee, Red Delicious, Golden Delicious, Boshghabi, and Shaki to rosy apple aphid under field and greenhouse conditions. The damage level by rosy apple aphid was significantly different among the tested cultivars precisely three weeks after infestation in both field and greenhouse conditions. The least leaf curling was observed on Shaki, while the most deformation was detected on Golden Delicious. There was positive correlation between damage in greenhouse and field studies. In addition, the lowest and highest numbers of aphids were observed on Shaki and Golden Delicious, respectively. Consequently, our results demonstrated that among the cultivars tested the Shaki cultivar is moderately resistant to rosy apple aphid and has the potential to be used in the integrated management of this aphid.

Abstract
Background: Recently, the use of probiotics in preventing and treating the immune system diseases through changes in blood factors has attracted the attention of researchers. Therefore, the aim of this study was to evaluate the effect of Lactobacillus plantarum and Bifidobacterium B94 on changes of blood factors, influencing the autoimmune system diseases.
Materials and Methods: The rats used in this study were divided into four groups (n=10 each), including control (saline), damage with Ethidium bromide (EB), L. plantarum and Bifidobacterium B94 treatment groups. In damage and treatment groups, a single dose of 3μL EB was directly injected into hippocampus of rats for inducing demyelization. Also, in control group, the same amount of saline was used. Then 2×108 probiotic bacteria were administered by gavage for 28 days. Then serum calcium and cholesterol levels were measured. Data were analyzed by one-way ANOVA and Tukey post-hoc tests (p≤ .05).
Results: The results showed that level of blood serum calcium increased insignificantly in the L. plantarum and Bifidobacterium B94 treatment groups compared to control group. Also, the level of blood serum cholesterol decreased insignificantly in both treatment groups compared to control group.
Conclusion: Probiotics are used for preventing and treating some of the common autoimmune diseases such as MS. Previous studies showed that probiotics affects some of the blood parameters such as calcium and cholesterol while decrease or increase in these parameters is effective in the improvement of MS. Although no significant finding has been obtained in some of these studies, they have almost confirmed the recommendation of probiotic consumption.
