Rhetorical questions are those that, according to time and local condition, have a function, beyond rhe gaining awareness and information. In addition to having an interrogative structure, these sentences imply another meaning as the secondary meaning. But in some cases, according to a special textual context, the existence of one or more weak implicit meaning or meanings between the semantic superstructure in rhetorical questions and main implicit meaning, can be proved and caught. These weak implicit meanings can neither be ignored nor be considered as the main secondary meaning. Based upon that, the problem which is stated in this research is that, with regarding to the possibility of catching such implicit meaning(s) from rhetorical questions , what is the nature and statuse of these additional implicit questions? And assuming acceptance of their existence, whether the production of meaning in rhetorical questions is still instantly? or according to the proposed theory in this research, the production meaning approach in rhetorical questions includes some processes and levels?
The approach of this research is analytic-applied approach and case study in some poems of prominant persian poets that there is a positinal stop in the structure of these poems. The results of this research reveals that , based on the author's prediction, the production of meaning in rhetorical questions has a process approach with three levels, in which, a second meaning layer is produced between superstructure and main implicit meaning (third semantic layer), that can be named as mediator semantic layer.

The simile formation process is based on the combined function of the two paradigms of selection and combination; Selection of phenomena and their combination, which is done with the purpose of conceptualization and Meaning production. Each of the simile components in both axes of selection and combination act as a network in the meaningful communication; Therefore, the communication of the simile components creates a special semantic system. In this system, each of the components is considered as a sign and plays a certain semantic role. The issue of this research is to investigate the symbolic system of simile and explain the process of signification of its components. The aim is to determine how a discourse system emerges in the form of analogy and the process of producing meaning in it. For this purpose, it is shown in the analytical-explanatory method how the poet, in the role of the subject, interacts with the “simulated” as an object in a special situation, and the result of this interaction is the mental perception that is determined by the “simulated to”. The result of the research shows that simile has a symbolic system and this system is associated with discursive, phenomenological-perceptual aspects and dynamic flow of meaning.

Despite all the efforts of professors and students, learning the four language skills of French in academic institutions has always been accompqnied by challenges. One of these skills is written production, in which students make numerous mistakes. We believe that identifying and analyzing areas of error can be effective in improving their writing skills. In the present study, using an analytical-descriptive method, the written productions of a group of students on a B1 level topic were examined. The data collection tool is the DELF B1 evaluation grid with ten criteria for writing correction. The participants in this study show that 42 percent of students had very good and good averages, and 58 percent had average and weak scores. The target population of this study performed acceptably in only three skills-coherence and logical structure, the ability to present events, and adherence to the topic-out of the ten criteria in the evaluation grid. However, they have not yet achieved the necessary skills in the other seven criteria. The areas of errors revealed in this research could serve as topics for further studies to extract and analyze errors in each domain.

This study investigates the instructional strategies Vietnamese EFL lecturers prefer to employ to teach productive skills of general English in online and face-to-face teaching environments. Thirty-eight lecturers from 6 Vietnamese universities participated and responded to a questionnaire with 29 close-ended questions detailing instructional strategies. Four of the participants were invited to join the semi-interview about the reasons for their preference for instructional strategies. The collected data were analyzed with descriptive statistics for Quantitative data and content analysis for qualitative data. The findings indicate that the most favored strategy in both teaching environments is describing pictures while opinion sharing and group discussion are much more favorable in the face-to-face than in the online teaching environment. Additionally, certain strategies are preferred in the face-to-face setting over instruction in the online setting and vice versa. Some primary reasons for lecturers’ preference for instructional strategies were identified and participants gave some recommendations of choosing appropriate strategies for teaching productive skills via interviews. These findings highlight EFL lecturers' preferences in selecting instructional strategies to teach English productive skills in the two teaching contexts and underscore implications for choosing proper instructional strategies.

Rural handwoven carpet weavers, particularly in the context of handmade silk carpet production, grapple with significant challenges concerning recognizing all stakeholders and establishing timely connections. These challenges have a substantial impact on the adoption of innovation in carpet production and the overall enhancement of productivity. This research was conducted to scrutinize the communication network of carpet weavers within the Knowledge and Innovation System (KIS) of handmade silk carpet production in rural areas. Data were gathered through interviews with 270 rural households in Zanjan province, specifically in the Tarom, Khodabandeh, and Zanjan counties, utilizing a structured questionnaire. Social Network Analysis (SNA) in UCINET was employed to examine the interactions among these actors, and graphical representations were created using Net Draw. The results revealed that the network's density varied across different levels, showing weakness in some cases, moderate strength in others, and strong connections in select instances. The connections of carpet weaving families with other actors within the KIS were predominantly localized. Among these families, those utilizing the home-based wage production method exhibited the most extensive interactions. The individuals designated as "FMs" (likely referring to family members) and "WNVKRs" (possibly local experts) demonstrated the highest degree of connection and influence within the network of weavers' interactions

Trissolcus vassilievi (Mayr) (Hymenoptera: Scelionidae) is one of the most important egg parasitoids of the common sunn pest (CSP), Eurygaster integriceps Puton (Hemiptera: Scutelleridae) in Iran. In this study, the fitness of two populations of T. vassilievi was studied on two populations of hosts in terms of life history parameters. Two populations of T. vassilievi were selected: 1/ Tabriz (as a temperate area), and 2/ Varamin (as a subtropical area), as well as for CSP. Moreover, regarding that outcrossing between populations can produce progeny with superior characteristics, the progeny of reciprocal crosses between original populations also were examined on a single host. The crosses between the two populations caused 13.9-18.5% higher net fecundity than maternal populations which suggests fecundity to be a function of maternal phenotype. The intrinsic rate of increase showed minor differences among treatments which varied between 0.291±0.003 to 0.305±0.003. The partial advantage of the Varamin wasps over the Tabriz ones and the crosses over the original populations was obvious. Such differences may be used to obtain more efficient parasitoids in augmentation programs.

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 The aphid parasitoids, Aphidius colemnai Viereck and A. matricariae (Haliday) (Hymenoptera: Braconidae: Aphidiinae) have high potential as the most effective biological control agents for controlling the cotton aphis Aphis gossypii Glover (Hemiptera: Aphididae). In this investigation, the effect of five constant temperatures (10, 15, 20, 25 and 30 °C) on the reproductive parameters was studied at 65 ±5% relative humidity and a photoperiod of 16L: 8 D hours In this study, the newly laid (one- day old) eggs were reared on third instar nymphs of cotton aphid, and the pupal and adult stages of the parasitoids were recorded daily, until the last individual was found dead. The experiments were carried out with 15 replications at each temperature. The results revealed that the gross fecundity and fertility rates were significantly different at all tested temperatures for both species (P

Mnemiopsis leidyi population activities first were recorded during the coastal observations in 2001 in which its population considerably increased afterward and now sustained the southern Caspian Sea. Maximum summer-autumn M. leidyi abundance was recorded in euphotic layer in 2002 (851±85 ind.m^-3) and maximum biomass was in 2001 with 48.1±14.4 g.m^-3) while minimum were in aphotic layer. In years 2003 to 2011, M. leidyi abundance and biomass sharply declined to 1-843 ind.m^-3 and 0.07-37.7 g.m^-3, respectively. The length-frequency distribution of Mnemiopsis showed larval, juveniles and transitional stages that made up 98.6% of the total population. In the southern Caspian Sea, Acartia tonsa was the highest number of mesozooplankton species (36 species) which decreased tenfold after Mnemiopsis invasion during 2001-2010. Fecundity experiments of Mnemiopsis showed the average of 8 eggs. day^-1, with a maximum of 35 eggs.day^-1which increased with increasing body length. The main food was larger amounts of zooplankton prey such as copepodites and adult of A. tonsa. It seems the sharp decreased of Mnemiopsis abundance could be related the decreasing of ova reproduction; and food ability is the main reasons of M. leidyi sustained in the southern Caspian Sea. The objective of present study was to provide information about parameters influencingthe M. leidyi decreased after initial bloom invasion in the southern Caspian Sea.

Today, financial development is one of the main drivers of economic growth and development. Since developing countries are focused on the rapid expansion of economic growth, they have taken steps toward the development of financial markets. However, the consequences of financial development on environmental quality are not clear. In addition, since the emission of carbon dioxide caused by production is significantly different from the emission of carbon dioxide caused by consumption in some countries (such as China). Therefore, this article examines the impact of financial development on the consumption-based CO₂ emissions for a panel of 17 developing countries during the period of 1990-2019 with a Panel- Quantile approach. Empirical findings show that the effect of financial development on consumption-based CO₂ emissions is positive and significant in all quantiles. In addition, this study considers gross domestic product, rental rates of natural resources, trade openness, and globalization as control variables. The results of this study provide new evidence for policymakers to maintain environmental quality by focusing on the link between financial development and consumption-based CO₂ emissions.

Aggregation and concentration of industries and the production of more complex products due to economies of scale can cause technology spillover. The development of industrial and complex processes requires energy, and the use of energy causes carbon emissions. Now this question arises, what are the effects of technology and industrial agglomeration on the environment? The purpose of this research is to evaluate the effect of economic complexity and industrial agglomeration on carbon emissions in a panel of emerging economies during the period 1990–2022. For this purpose, first, the industrial agglomeration was calculated based on the location entropy index, and then, in the new panel approach, the method of moment quantile regression (MMQREG) was used to investigate the effects of economic complexity and industrial agglomeration on carbon emissions. The results showed that increasing the economic complexity index has different effects on carbon emissions. The results of parameter estimation showed that industrial agglomeration increases carbon emissions in high quantiles. The results show that economic growth and energy consumption increase carbon emissions in all quantiles, and urbanization helps to preserve the environment. The results of Dumitrescu and Hurlin's panel causality test show a two-way relationship between industrial agglomeration and carbon emissions and a one-way relationship between economic complexity and carbon emissions.

Detergents are a part of human life and are consumed for different purposes, particularly hygiene. In recent years, the detergent industry has experienced significant changes as a result of environmental concerns, the availability, and cost of raw resources and energy, consumer preferences, demographic and sociological trends, as well as global economic and political factors. Several review papers have been published on detergents, but no bibliometric research has been conducted in this field. This study aims to assess the trend of detergent research and show the related hotspots by conducting a bibliometric analysis based on 37650 published articles from Scopus from 2000 to 2022. Numerous significant aspects of these articles, such as subject categories, journals, authors, countries, and keywords, were examined systematically. According to the findings, the number of detergent-related papers has increased significantly over the past two decades. The United States was the leading country in terms of both quality and quantity, followed by China and Brazil. In addition, Detmann, E. from Sweden was the most productive author. Keyword analysis suggests that current research has focused on the development of effective cleaning products that are safe for humans and the environment.

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.

The effect of various host plants including chickpea (varieties Arman, Hashem, Azad and Binivich), common bean (variety Khomein), white kidney bean (variety Dehghan), red kidney bean (variety Goli), cowpea (variety Mashhad), and tomato (variety Meshkin) on the reproductive performance and growth indices of the cotton bollworm, Helicoverpa armigera (Hübner) was determined under laboratory conditions (25 ± 1°C, 65 ± 5% RH and a 16:8 h light:dark photoperiod). The highest rate of gross fecundity, gross fertility, net fecundity, net fertility, mean daily eggs and mean daily fertile eggs were observed on chickpea Arman (2947.8 ± 7.8, 2933.0 ± 7.8, 2404.2 ± 7.1, 2392.2 ± 7.1, 170.9 ± 0.4, and 170.1 ± 0.4 eggs female^-1, respectively), whereas the lowest values of these parameters were on tomato Meshkin (847.5 ± 9.2, 673.8 ± 7.3, 225.5 ± 2.6, 179.3 ± 2.1, 67.9 ± 0.7 and 54.3 ± 0.5 eggs female^-1, respectively). The development index of overall immature stages varied from 1.10 to 1.57, with the minimum on tomato Meshkin and the maximum on chickpea Arman. Also, the fitness and standardized insect-growth indices were highest (0.349 ± 0.009 and 0.058 ± 0.001 gr day^-1) and lowest (0.052 ± 0.001 and 0.013 ± 0.000 gr day^-1) on chickpea Arman and tomato Meshkin, respectively. The Weibull model sufficiently described the shape of the survivorship curve of adult H. armigera from life-table data. A significant fit was obtained with the Weibull model for H. armigera in all experimental host plants. The results of reproductive performance, growth indices and the cluster analysis showed that tomato Meshkin was partially resistant to H. armigera.

Different types of soil erosion including gully erosion occur in many parts of Iran. The west of Iran is further threatened by gully erosion due to its specific physical and climatic conditions. However, few studies have been carried out to study the sediment production of gully erosion in Iran. This research was therefore conducted to measure storm-wise sediment production of gully erosion in the west of Iran. To achieve the study objectives, 48 gullies located in three small watersheds viz. Darreh-Shahr, Abbas-Abad and Hollowsh in Ilam and Lorestan Provinces were monitored. The volumes of gullies were measured before and after 5 rainstorms for Darreh-Shahr and Abbas Abad watersheds and 6 rainstorms for Hollowsh watershed from 2005 to 2007. Sediment production was calculated on storm basis for each gully. The results revealed that the minimum and maximum volumes of gully erosion were 0.002 and 1.010 m³, respectively, for one millimeter of rainfall. The results indicated that soil moisture, percentage of silt and clay, amount and intensity of rainfall and drainage area were the most important factors on formation and sediment production of gully erosion.

Life table gives the most comprehensive explanation of the survivorship, development, and reproduction of a population. The life table parameters of an aphidophagous midge, Aphidoletes aphidimyza were studied on different densities (5, 10, 20, 40, 60, 80) of third instar nymphs of Aphis gossypii as prey in a growth chamber (25 ± 1 °C, 70 ± 5% RH and a photoperiod of 16L: 8D h). The pre-ovipositional period of female A. aphidimyza was reduced as prey density increased with no significant difference. The oviposition period was 3.833 ± 0.401 and 5.5 ± 0.463 days in lowest and highest prey density, respectively. Fecundity increased significantly with increasing prey density. The lowest fecundity was obtained at density of 5 preys/day (49.667 ± 6.053 eggs) and the highest was at density of 80 preys/day (104.25 ± 7.78 eggs). Intrinsic rate of increase (r_m) ranged from 0.110 ± 0.016 to 0.166 ± 0.014 d^-1 with increasing prey density. Net reproductive rate (R₀) was positively dependent on prey density. The peak reproductive values showed that female aphidophagous midge at ages of 17, 18, 19, 22 and 25 days made the highest contribution to the population when reared on 5 to 80 preys in a day, respectively. However, mean generation time (T) ranged from 22.42 ± 0.55 to 24.47 ± 1.04 days. It was concluded that the increase in the density of third instar nymphs of A. gossypii significantly affected the demographic parameters of A. aphidimyza and it had a better reproductive performance in higher prey densities.
