The aim of the present study was to examine whether Metacognitive Intervention (MI) in their first language (L1) had any significant effect on English as a Foreign Language (EFL) learners’ Working Memory (WM) in listening comprehension when they received it. In addition, it measured whether gender had any effect on EFL learners’ listening comprehension when they receive MI through L1. To this end, 60 Iranian EFL learners were selected through a Quick Placement Test and were assigned into two male and female experimental groups. These experimental groups received an eight-week intervention program, designed by the pedagogical cycle proposed by Goh and Vandergrift (2022). After the metacognitive intervention in L1, two posttests including a working memory capacity test and a listening comprehension test were administered. The findings indicated that there was a significant effect on EFL learners’ working memory in listening comprehension after they received MI in L1. It was also found that gender had a significant effect on the EFL learners’ working memory and listening comprehension when they receive MI in L1. The findings might contribute to assisting language instructors to adopt strategy-based approaches to teaching listening. Furthermore, curriculum designers and ELT policymakers might consider metacognitive intervention as an effective teaching approach and add it to EFL learners’ curriculum.

The beet cyst nematode (BCN) (Heterodera schachtii), and beet curly top virus-severe (BCTV-Svr) (Curtovirus betae) are two important pathogens of sugar beet fields worldwide. Therefore, the reaction of 14 genotypes was separately assessed, using Jolgeh and Sanetta cultivars as susceptible and resistant controls, respectively, in completely randomized design experiments for BCN and BCTV-Svr. Reactions were based on the cyst and egg counts and symptoms severity index. Experiments were performed in the greenhouse of Tarbiat Modares University, Tehran, Iran, and were repeated twice independently. Based on the results of initial experiments, the S1-960090, S1-940324, S1-960294, and S1-960284 genotypes resistant to the BCN were selected for further investigation. Furthermore, the reaction of the four selected genotypes to BCN, BCTV-Svr, and the combination (mixture) of the two pathogens was evaluated by analyzing their growth, physiological, and biochemical characteristics, and virus accumulation. Resistant genotypes showed higher levels of defense-related enzymes such as catalase, guaiacol peroxidase, and polyphenol oxidase, whereas susceptible genotypes exhibited significant reductions in photosynthesis, greenness, and chlorophyll a, b, and carotenoid content compared to non-inoculated and resistant plants. This is the first study conducted to search for dual-resistance sources against two devastating pathogens that frequently occur in the sugar beet-growing regions of Iran. Based on the results of this experiment, genotypes S1-960090 and S1-940324 were identified as resistant to both pathogens and are recommended for breeding purposes.

Horizontally curved bridges have been observed to suffer severe structural damage during past earthquakes so determining the seismic performance of curved bridges is crucial due to the complex dynamic behavior of these structures because of their irregular geometry and non uniform mass and stiffness distributions. Analyzing and plotting the capacity curve of these structures can be costly and time-consuming. As a result, many efforts have been made to simplify the structural models of these bridges and reduce the computational workload required for their analysis. This article presents a straightforward method to convert the multi-degree-of-freedom system of these structures into an equivalent single-degree-of-freedom system, ensuring that the capacity curve of the equivalent structure closely matches that of the original structure with minimal error. In this study, the OpenSees program was used to extract the stiffness and mass matrices of a curved bridge structure. These matrices were then condensed into one-by-one matrices for mass and stiffness using dynamic condensation equations. The characteristics of these matrices were applied to a single-degree-of-freedom stick model. In this model, the obtained mass is placed at the top of a stiff rod (stick), which is connected to the ground by a spring (zero-length element) with the equivalent stiffness obtained. A nonlinear static pushover analysis of the bridge structure was performed to obtain the capacity curve. An equivalent bilinear curve was then drawn, and the yield shear force and yield displacement were determined. The nonlinear behavior of the single-degree-of-freedom structure was modeled using the Steel02 material available in the OpenSees library by zero length element utilizing the yield shear force and yield displacement magnitudes of the curved bridge. The capacity curve of the stick model, which has a single degree of freedom, showed an error percentage of 7% compared to the bridge's capacity curve. This indicates acceptable compliance with the capacity curve of the main structure, making the stick model a viable alternative for repeated analysis of the curved bridge structure. This study also included a sensitivity analysis to investigate the effects of increasing the curvature radius and decreasing the curvature angle of the bridge on its capacity and effective mass. Due to the dynamic condensation of the curved bridge structure, the influence of all degrees of freedom was considered in the stiffness and mass matrices, unlike methods that rely solely on the first vibration mode for dynamic condensation. Comparing the capacity curve of each structure with that of an equivalent single-degree-of-freedom system revealed that the structure's capacity increases with a larger curvature radius. In contrast, the lowest capacity was observed in the straight bridge scenario. Additionally, modal analysis of the studied models showed that increasing the bridge's curvature radius leads to a longer structural period, while a decreasing curvature angle has a similar effect. However, the period of the straight bridge was longer than all the other models. Furthermore, as the curvature radius increased, the mass contribution percentage of the first mode in the translational x-direction decreased, whereas the translational mass contribution percentage in the y-direction and the rotational mass contribution around the z-axis increased.

Despite the particular importance of the subject of soil-structure interaction, unfortunately, this issue has received little attention from engineers, and seismic codes have not given much recommendation to consider its effects. Seismic wave frequencies vary continuously, and the stiffness of springs and damping of dampers connected to structural supports also vary with the loading frequency. To simplify time-domain numerical analysis, a constant target frequency can be used to keep stiffness and damping values constant. In the substructure method proposed in this study, the optimal target frequency is the one that yields results that most closely match those of a more accurate nonlinear 3D model analyzed using a direct method. A common simplification is to ignore the foundation’s non-linear response, justified by design requirements to prevent permanent deformation and the complexity of frequency-dependent soil behavior. Though not fully precise, this approach (considering soil heterogeneity and optimal target frequency) offers a forward-looking analysis and a basis for future nonlinear studies. This study presents a three-dimensional (3D) numerical model for analyzing the seismic response of soil-foundation-structure systems embedded in granular soil (with different relative densities) considering the effects of soil heterogeneity (With varying shear modulus with depth and compatible with the practical HSsmall model). The model is capable of accounting for the effects of loading frequency along with the radiation damping of the soil system and can integrate with the widely-used substructuring method considering an optimal target frequency. After verifying the proposed model, the dynamic equilibrium equations of the substructuring system were solved in the time domain using Matlab software. The target frequency was determined using i) Case 1: the fundamental frequency of the soil (or the dominant frequency of the excitations), ii) Case 2: the fundamental frequency of the structural system, iii) Case 3: the fundamental frequency of the soil-foundation-structure system; iv) Case 4: the fundamental frequency of structure with static stiffness and damping support (Case 4); and v) the fundamental frequency of fixed base structure and modified stiffness, and the results were compared together. A comparison of the impedance (dynamic stiffness and damping) of foundations situated on homogeneous and heterogeneous soil, as well as an investigation of the structural response in both cases, is another objective of this research. The analysis results demonstrated the accuracy of the proposed model and the acceptable calculation speed for estimating the dynamic response of structures located on heterogeneous soils under frequent operational earthquakes. The results also showed that with an increase in soil relative density, the seismic behavior of structures on homogeneous and heterogeneous granular soils converges. For instance, the response of the foundation on homogeneous soil bed with relative densities of 55%, 75%, and 95% is on average 23%, 19%, and 15% lower than that of heterogeneous soil, respectively. Additionally, for determining the target frequency, the use of frequency‐independent Kelvin–Voigt models (i.e., Cases 1-5) provides acceptable responses. According to the data presented in Table 4 and Figs. 9 and 10, the following conclusions can be drawn: 1) The soil's fundamental frequency (Case 1) yielded the least precise results. 2) While Case 3 offered the most favorable response, closely matching the direct method, determining the soil-structure system's fundamental frequency through complex integration in numerical software is often impractical. 3) Employing the target frequency in Case 2 produced more satisfactory results than Case 1. 4) Cases 4 and 5 generated nearly identical frequencies. Compared to Case 2, these cases enhanced response accuracy, bringing them closer to the best response (i.e., Case 3). Therefore, for practical applications, it is recommended to utilize the fundamental frequency from either Case 4 or Case 5 instead of the soil-structure system's fundamental frequency (Case 3) to establish the optimal target frequency.

Beet western yellows virus (BWYV), a species of the genus Polerovirus in the family Luteoviridae, is an agriculturally important virus infecting over 150 plant species in 23 dicotyledonous families worldwide. A survey of BWYV in canola fields in Golestan and Tehran provinces of Iran using indirect triple antibody sandwich enzyme-linked immunosorbent assay (TAS-ELISA) indicated 8.3 % infection. The presence of BWYV was confirmed by amplification of the coat protein (CP) gene of the virus via running a reverse transcription-polymerase chain reaction (RT-PCR) on total RNA extracted from ELISA positive leaf tissues. DNA sequences of the BWYV coat protein (CP) gene of seven Iranian isolates were determined and compared at the nucleotide (nt) and amino acid (aa) levels with those of twelve BWYV isolates from different countries deposited in GenBank. Sequence analysis data showed that the identity of BWYV-CP at nt and aa levels among the Iranian isolates were 93.4 % to 100 % and 93.2 % to 100 %, respectively. The maximum similarity of isolates at nt and aa levels were 97.2 and 96.6 %, which occurred among two Iranian isolates (Ir 8 and Ir 100) and four isolates from France (L39967 and X13063) and England (L39973 and L39970). The recombination analysis among the nineteen isolates including seven Iranian isolates revealed that there was no distinct intra-specific recombination event among BWYV isolates. This is the first report of sequencing and analyzing of the BWYV CP gene of Iranian BWYV isolates.

Asiatic citrus canker is a devastating disease resulting in drastic economic losses in citriculture worldwide. Amongst three different types of the disease, i.e. A, A* and A^w, the A* type is genetically less known. In order to comprehend the behavior of the Asiatic citrus canker A*-type strain (Xanthomonas citri subsp. citri) in the vicinity of the host cells, a targeted semi-quantitative transcript analysis approach via RT-PCR was carried out. A subset of sixteen genes, as representative of different steps involved in phytopathogencity, was analyzed on the culture medium (as uninduced) and compared with the subset isolated from the infected Mexican lime (Citrus auarntifolia L.) plants (as induced). The results showed that certain genes were up-regulated in induced condition, suggesting a putative role in bacteria-host interaction. Furthermore, the transcripts in induced condition could be classified into constitutive, early- and late-responsive genes, demonstrating their functional relevance during the host-pathogen interaction.

Heidegger believes that among the Greeks, Aletheia means "Unhiddeness," which is an essential attribute for beings. However, by referring to the world of ideals, Plato considers Truth as conformity and transfers it to human reason. In this approach, the truth lost its intrinsic character and became the correspondence of cognition with its objective reference. This epistemological transformation led to the emergence of prevalent dualities in philosophy. Although Mulla Sadra has fundamental similarities with Heidegger, he considers truth to have multiple meanings by gradation. In the third phase of his philosophical thought, by reaching divine manifestation -with his special interpretation of Platonic philosophy- he abandons his earlier conventional dichotomies in philosophy. At this stage, Mulla Sadra reaches Real Unity and accepts Plato's truth as something with existential gradation. In this paper, we are trying to examine the views of Heidegger and Mulla Sadra while briefly analyzing the truth of Plato. Finally, we will extract Sadra's criticisms of Heidegger's thoughts about truth.

The attitude or behavior, which is not based on logical actions- and cause and effect relations, has irrational origins;  it happens due to a person's fear, threat, habits, and the unknown factors which he she believes to prevent the unbecoming events, called “superstition”. An increase in the literacy level and the popular culture in the society leads to a decrease in superstitious beliefs. It must be acknowledged that even modern people cannot reject superstitions, or get rid of them actually. This study has examined the causes of these prevalent beliefs and the way people apply them, via content analysis. Although the prevalence of superstition origins is established on irrational bases, people have applied them to gain benefit by impelling and propagating the folklore, preventing harm by inhibition, alleviation, turning the evil (scapegoat), and empathy.

Citrus tristeza virus (CTV) is among the most destructive pathogens of citrus and causes substantial economic losses in citrus-growing industry worldwide. Considering recent distribution of this pathogen and its capability of transmission by existing aphid vectors in Iran, detection of this virus is enforceable for controlling the damage caused by this pathogen in Iran, as one of the major citrus producing countries. Toward this aim, developing a reliable and sensitive detection method such as enzyme- linked immunosorbant assay (ELISA) would be the first step to detect CTV in large scale screenings of field samples. As the serological method requires great amounts of specific antibody, the consequent preparation of a large scale antigen source for immunization process is necessary. In this study the coat protein gene of CTV (CP25) was amplified by polymerase chain reaction from a cloned CP25 gene in pTZ57R/T and subcloned in pET26b expression vector and named pET-CP25. Two Escherichia coli strains of BL21 and Rosetta Gami (DE3) were transformed by pET-CP25. Expression of recombinant protein was induced by IPTG. The authenticity of recombinant protein was confirmed by western immunoblot analysis using a polyclonal antiserum against CTV particles. The results indicated that CTV coat protein gene was expressed in E.coli. This recombinant protein could be used as a source of antigen for immunization process.

This study is a stylistic narratological analysis of Ravāyat-e Moharram (The Narrative of Moharram) by Seyyed Morteza Aviny based on a framework adopted from Randall’s (1999) Narrative Intelligence Theory. Although many claims have been made about the unique qualities of Aviny’s narratives, none of his works have been academically analyzed to confirm the narratological features of his works. The researchers believe that scientific analysis of Aviny’s works based on reliable theories of narratology can substantially contribute to a better understanding of special qualities of his style, and using them in new forms and contexts. In the present study, mechanisms contributing to the promotion of narrative intelligence and their realization in Ravāyate Moharram are quantitatively and qualitatively analyzed using Labov’s (2001) narratological model as a structural instrument. The linguistic manifestation of some narratological features of Aviny’s prose are discussed from a stylistic perspective.
