Sound substitution is a process whereby a phoneme in a loanword is replaced by its closest phone in the borrowing language. Many English loanwords with consonants /T/, /w/, /k/ and /g/ have been adapted by Persian. None of these consonants exist as a phoneme in Persian. The pronunciation or substitution of these consonants by their closest phone in Persian depends on the phonological environment; the dental /T/ is replaced by [t] and [s] respectively in the onset and coda. The bilabial /w/ is replaced by [v] in the onset. However, since [w] is only used as an intervocalic consonant in Persian, it acts like an intervocalic consonant upon the declusterization of word initial /sw/. Therefore, it is not usually replaced by any consonant in this environment. Finally, the velar consonants /k/ and /g/ either change to palatal [c] and [Š] respectively or do not change at all, due to the phonological environment. This research aimed at explaining each of these sound substitution processes within the framework of optimality theory (Prince and Smolensky, 1993/2004). It presents arguments in favor of constraint rankings which cause the occurances of these processes.

Recitation of the Holy Qur’an has its own phonological rules. This paper addresses total nasal place and manner assimilation, known as “idgham”, that lead to “gemination with nasalization” and “gemination without nasalization”. The former which is accompanied by lengthening occurs in the environment where the /n/ in the coda position precedes one of the four sonorants /j/, /m/, /w/, and /n/ in the onset position of the following syllable. However, the latter which is not accompanied by lengthening occurs in the environment where /n/ in the coda position precedes either of the sonorant liquids /r/ or /l/ in the onset position of the following syllable. The present research aimed at identifying the constraints whose interactions cause either of these processes in the recitation of the Holy Qur’an within the framework of optimality theory (Prince and Smolensky, 1993/2004). The results of this paper are as follows: The [+long] geminated [n:.n] is the result of gemination of /n/ in the coda position with /n/ in the onset position. The [+long] geminated [m:.m] is the result of total nasal place assimilation of /n/ in the coda position with /m/ in the onset position. The [-long] geminated [r.r] and [l.l] are the result of total manner assimilation of /n/ in the coda position, respectively with /r/ and /l/ in the onset position. The [+long] geminated [j:.j] and [w:.w] are the result of both total nasal place and manner assimilations of /n/ in the coda position, respectively with /j/ and /w/ in the onset position.

This study employs graph theory to analyze the semantic network of Persian verbs among bilingual speakers. Situated within the frameworks of cognitive linguistics, lexical semantics (cognitive semantics), and computational linguistics, the research involves administering a questionnaire comprising 50 basic Persian verbs to participants, asking them to map the conceptual and intra-linguistic relationships between these verbs.The primary objective is to identify the most robust and frequent conceptual and intra-linguistic links among these verbs and to provide a detailed description of the graph structure constructed by bilingual speakers. The study seeks to address the question: What typology of conceptual and intra-linguistic relations is reflected in the graph patterns of non-Persian-speaking Iranians? The working hypothesis posits that semantic relations such as synonymy, antonymy, hyponymy, and collocation will manifest in this network.The methodology is field-based, and the instrument used is a localized questionnaire. Participants were instructed to diagrammatically represent any semantic relationships among the verbs provided.The findings demonstrate that the semantic graph constructed by Iranian bilinguals exhibits semantic relations such as synonymy (6.45%), reverse antonymy (34.94%), polysemy (7.79%), entailment (11.01%) (comprising "type-of" relations at 8.60% and "part-of" relations at 2.41%), as well as intra-linguistic collocation (28.22%). Among these, collocation, entailment, and antonymy were the most frequent relations, respectively.

Various factors, such as temperature stress, dietary changes, and the entry of contaminants and infections into the hemolymph, are known to affect insect immune responses by altering hemocyte profiles. The research focused on the hemocyte profile, hemogram across all biological stages, and the morphological and frequency changes of hemocytes in third instar larvae exposed to temperature stress. Cucumber fruits infected with insect larvae were collected and brought to the laboratory, where third instar larvae were extracted from the fruit tissue. The hemolymph was then collected, and after staining with Giemsa solution, hemocytes were identified under a light microscope. The hemogram analysis included measurements of DHC, THC, blood volume, and AHC across all biological stages. In third instar larvae, plasmatocytes and granulocytes were the most abundant, comprising about 56% of the hemocyte population. In contrast, prohemocytes were most frequent in the first instar larvae, accounting for approximately 37%. THC was highest in third instar larvae, indicating a direct correlation between hemolymph volume and total hemocyte count. Temperature stress had a significant impact on hemocyte numbers. Heat stress, with temperatures up to 30 and 35 °C, led to a notable increase in total cell count, granulocytes, and plasmatocytes. Conversely, cold temperatures resulted in a decrease in prohemocytes, plasmatocytes, granulocytes, and the total cell count compared to the control group. Additionally, temperature stress induced hemocyte deformation, with plasmatocytes and granulocytes showing the most pronounced changes under heat stress, including torn cell walls and loss of cell contents at 35 ^○C.

Climate change (CC) is one of the major challenges of our time that impacts rangelands regionally and globally. The rising vulnerability among pastoralists highlights the need to prioritize resilience thinking. Pastoralists' resilience refers to the ability of rangeland businesses to endure, adapt to, and remain flexible in the face of threats or challenges. This research was conducted with the primary goal of analyzing the factors that influence resilience from the perspective of pastoralists in Tehran province under CC conditions. This research was both goal-oriented and exploratory in methodology. The study sample consisted of 317 pastoralists selected through stratified random sampling. The data collection tool was a researcher-made questionnaire. Software SmartPLS was used for data analysis. The validity of the questionnaire was assessed using the average variance extracted, while its reliability was established by calculating composite reliability and Cronbach's alpha. Data were analyzed using the structural equation modeling technique with Smart PLS software. The structural equation modeling indicated that economic, institutional, ecological, physical, social, educational and extensional and individual factors had the greatest impact on Pastoralists' Resilience under Climate Change (PRCC) conditions. These factors explained 75.5% of the PRCC conditions.

Damage of both building and non-building structures (including the space structures) against earthquake is of great importance for civil engineers, because collapse of such large structures may have significant casualties and economic losses. Space structures are classified as large-scale structures and can cover a large space without columns. Seismic behavior of these structures is different from building structures. There are different types of space structures considering the geometrical aspects, which are effective in the damages causing economic and life losses. A space structure has three-dimensional behavior, and their higher-mode effects are remarkable. On the other hand, the weight of these structures is relatively low that may cause an unrealistic reduction in the calculation of seismic force in a static analysis. Therefore, the static analysis cannot capture their structural response effectively. Traditionally, the dynamic analysis is utilized for seismic design of space structures due to their complex structural behavior. Thus, in this paper, seismic design of two single-layer domes is performed using two dynamic analyses: time history analysis and response spectrum analysis. Although there are some studies on seismic design of domes, further investigations are required due to the structural diversity of different domes and the difference in their seismic behavior. Here, the ribbed and Schwedler domes under gravity and seismic loads are analyzed dynamically. The parameters of the design response spectral acceleration are based on ASCE7-16, and the site class (based on the soil type) is selected as “D”. Both horizontal and vertical components of seismic excitations are utilized in the dynamic analyses, because all these components are effective in design of a dome structure. The damping ratio is assumed to be 2% in the dynamic analyses based on the relevant literature.  In the response spectrum analysis, the vertical seismic load is expressed in terms of dead loads in the response spectrum analysis. In the time history analysis, seven ground motion records are selected based on the seismic zone. These ground motion records are scaled using both amplitude scaling and spectral matching approaches. The vertical components are scaled to the specific vertical design spectrum obtained from ASCE7-16. In this study, seismic design of the ribbed and Schwedler domes with a span of 36 meters and a height of 6 meters are carried out with some limitations on the member stress ratios and top nodal displacements. The structural designs based on the time history analysis and the response spectrum analysis are compared. The same cross-sectional areas are used in designs of the dome structures to compare the effects of these dynamic analysis methods better. In general, the top node displacement and stress ratios of the dome obtained using time history analysis is larger than that obtained using spectral dynamic analysis. Accordingly, the results indicate that the structure designed with the time history analysis is heavier than the structure designed with the response spectrum analysis. Obviously, although the time history analysis provides a better understanding of the dynamic behavior of the structure, it requires much higher computational cost than the response spectrum analysis.

The adsorption of polymeric systems onto reservoir rock through altering the wettability of rock surface improves oil recovery and reduces the unwanted water production. . In this study, the adsorption behavior of dilute polymeric systems based on sulfonated polyacrylamide  on the glass particles surfaces (representative of sandstone reservoirs) was investigated and the effect of this phenomenon on changing their surface properties was examined. Results show that crosslinked polymeric samples have lower adsorption on glassy surface comparing with uncrosslinked sulfonated polyacrylamide solution. Furthermore, the contact angle tests results showed that crosslinked samples change the surface property of glass particle less than sulfonated polyacrylamide solution. In addition the Langmuir isotherm model fitted the isotherm data better than the Freundlich model for these dilute polymeric systems. Furthermore, study of the thermodynamic of adsorption showed that their adsorption behavior on glassy surfaces is a spontaneous and exothermic process.

Background: Knee osteoarthritis (OA) is a major public health problem leading to chronic pain and increased years lived with disability This study aimed to assess lifestyle behavioral management in patients with Knee osteoarthritis among Iranian patients up to 6 months.
Methods and Materials: This study conducted at the Rheumatology Research Center of Tehran University of Medical Sciences (TUMS) in Tehran, Iran. In this educational controlled trial study, 130 eligible participants took part in control group (n = 66) and received just prescribed medications, or intervention group (n = 64) who received the lifestyle behavioral management plus medication. The program involved three two-hour and two one-hour group sessions over a one-week period. Data based on demographic characteristics and risky behaviors questionnaire as well as Functional Knee Assessment Test (FKAT) were collected at initial, 3-, and 6-month follow ups and analyzed by using SPSS₁₈.
Results: Of 130 participants, five individuals from intervention and eight individuals from control group were excluded over 6 months. Totally, 117 eligible participants in two groups of intervention (n = 59), and control (n = 58) completed the study. The mean age of participants in intervention and control group at base line was 59. 03 ± 6. 13 and 57. 85 ± 9. 31 years respectively. Despite being the same at initial time (P > 0. 05), Repeated Measure ANOVA test showed Significantly better improved disability in intervention group over time (P < 0. 001). Compared with control group, preventive behaviors were improved significantly in intervention group (P < 0. 05)
Conclusions: This study revealed that the multidisciplinary program could significantly reduce risky behaviors and disability up to six months in intervention group.

Dispersion type of layered clay plated in aqueous media creates different structures and affects the final properties of its suspension. On the other hand, the presence of different electrolytes in some industrial applications affects the stability of clay suspensions. Considering the application of clay nanoparticles in various industries and the importance of this subject, in this research, the effect of preparation method, nanoparticle concentration, type and ionic strength of electrolytic medium and time elapsed on the stability behavior of laponite nanoparticles suspensions were studied. The results showed that preparing of the suspensions indirectly, results in more stable samples. It was observed that with increasing of sodium chloride concentration, the repulsion between the clay plates decreased and the phase separation and instability of the suspensions increased at higher NaCl concentrations. Furthermore, it was seen that in all electrolyte media, gel-like structure develop with increasing of nanoparticle concentration. In presence of bi-valance CaCl2 salt, most of suspensions were unstable and have two phases and increasing of this salt concentration had not significant effect on their stability. In electrolyte media containing mono- and bi- valance salts (studied in this research), concentration of calcium cation determines the type of stability behavior of laponite nanoparticles suspensions.

The Economic Cooperation Organization (ECO) is the result of the political will of its three founding countries for economic convergence, which had previously symbolized in its predecessor, the Regional Cooperation for Development (RCD). The desire of Iran and two other neighbouring countries to fill the void of past regional cooperation led to the revival of RCD in ECO in 1984. The collapse of the Soviet :union: and the independence of the Muslim Republics led to expansion of the organization. During 1992-96, ECO realized the main areas and priorities of cooperation and established several regional institutions and since 2006 entered the implementation phase of its agreements and strategies. This research seeks to analyse the activities of ECO to achieve the set objectives and evaluate the degree of their realization.. The main question of the essay is whether ECO has been able to realize the goals of regional integration? What has been the role and influence of Iran in the successes and failures of ECO? And can we still hope for the success of this organization? The research hypothesis is that ECO has not achieved much success in the implementation of a large number of agreements and regional plans, and its activities have not had a tangible impact on regional development and prosperity. In the meantime, Iran has played a large role in the failure of ECO. The research method is descriptive-analytical, and the data has been collected and analysed by referring to ECO documents, library sources and field experiences.

Background: This study is an extended follow up of the original trial study (NCT00600197) that has been published in the clinical journal of pain. This trial aimed to explore if the proposed multidisciplinary program could improve quality of life and disability of the patients suffering from chronic low back up to 36 months. Methods and Material: In this Clinical Randomized trial seventy percent (139 of 197) of the participants who had taken part in the original study including 66 patients in intervention group and 73 patients in control group were followed up to 36 months after intervention. The intervention group continued receiving monthly motivational consultation and booster classes plus oral medication but the other group received just medication. Data on measures of Short Form 36 (SF-36) Quebec Disability Scale (QDS) and Ronald Morris Disability (RDQ) were collected at 3-6-12-18-24-30- and 36-month follow ups and analyzed through RMANOVA. Results: The 2 groups were comparable regarding all baseline characteristics (P > 0.05) except for education level that was better in intervention group (P = 0.01). Two groups were improved regarding all studied variables over time up to 36 month (P < 0.001) Moreover the intervention group in comparison with the control group had consistently better outcomes regarding all variables. There were no significant differences within each group by time in terms of all variables (P < 0.05). Conclusions: The proposed multidisciplinary program could reduce low back pain and improve quality of life and disability up to 36 months in chronic low back pain patients.

A specimen of an ascomycetous fungus collected during a field trip was identified as Gymnoascus Baran. Soil samples collected from 0-20 cm depth were studied for isolation of fungi using a soil dilution plate method. Based on the morphological and molecular characters the specimens were identified as Gymnoascus reesii. Genomic DNA was extracted and a nuclear rDNA region, containing the internal transcribed spacers 1, 2 and 5.8S gene of rDNA (ITS) were amplified and PCR products were sequenced. Amplicon was purified, sequenced and submitted to the GenBank (Acc. No. JQ387570-71). The resulting sequence (600 bp) was submitted to a BLAST search to find most similar sequences in GenBank. The search results showed highest similarity of Iranian isolates to other isolates of G. reesii from GenBank. In the light of literature on ascomycetous fungi, Gymnoascus Baran is a new record for Iran mycoflora. The specimens are kept in fungal collection of the Department of Plant Protection, Razi University, Kermanshah, Iran.

A time-domain approach is presented to calculate electromagnetic fields inside a large Electromagnetic Pulse (EMP) simulator. This type of EMP simulator is used for studying the effect of electromagnetic pulses on electrical apparatus in various structures such as vehicles, a reoplanes, etc. The simulator consists of three planar transmission lines. To solve the problem, we first model the metallic structure of the simulator as a grid of conducting wires. The numerical solution of the governing electric field integral equation is then obtained using the method of moments in time domain. To demonstrate the accuracy of the model, we consider a typical EMP simulator. The comparison of our results with those obtained experimentally in the literature validates the model introduced in this paper.
