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.

Urban growth boundaries are considered one of the key tools for controlling and managing the physical development of metropolitan areas. Uncontrolled and unplanned expansion in these regions has become a major challenge for urban and regional planners and managers, as this process leads to the destruction of agricultural lands and natural resources. The aim of this research is to simulate and assess future changes in growth boundaries in the Isfahan metropolitan area with the goal of preserving environmental resources and controlling physical expansion. In this regard, by adopting a positivist approach that follows an analytical and measurement-driven process, satellite imagery was utilized to assess changes in the physical expansion of the Isfahan metropolitan area. Artificial neural networks and machine learning algorithms were employed to predict the extent of future physical growth, and the projected growth boundaries were delineated. The research findings indicate that the Isfahan metropolitan area has experienced significant uncontrolled expansion, particularly in terms of physical development, over recent decades, and the reduction of agricultural and natural lands has become one of its major challenges. Based on the conducted simulations, the proposed growth boundaries can serve as an effective tool for managing and planning urban-regional development and preventing further degradation of natural resources and lands.

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

Education and research are fundamental pillars of educational systems, including agricultural higher education institutions. However, an inadequate balance between these components can lead to a deviation from the primary goals of these institutions. This study aimed to conduct a pathological analysis of the equilibrium between education and research in the higher education system of agriculture in Iran. “Three-pronged pathology model” was utilized, comprising components of “context” (including knowledge, moral, individual-psychological, satisfaction, and the thematic nature), “behavior” (including planning, coordination, control, and monitoring), and “structure” (including demonstrative, diversity, consequence, and political). This quantitative study is applied in purpose, non-experimental in design, retrospective in timing, survey-based in data collection, and descriptive-causal comparative in data analysis. The data collection instrument was a researcher-developed questionnaire, with face and content validity confirmed by experts. The reliability of the questionnaire was established using Cronbach's alpha for each variable (0.704 ≤ α ≤ 0.902). The statistical population comprised faculty members from agricultural departments of public universities in Iran (N=3335), with a sample of 307 selected. Results indicated a tendency among faculty members towards research activities. The greatest gap and imbalance between education and research were observed in the areas of context, followed by structure and behavior. This indicates that the existing context and structure push faculty members towards research activities for their sustainability and advancement in the agricultural higher education system. This poses a serious issue that must be addressed by policymakers and decision-makers.

We present a method to predict the flexible and rigid regions based on sequence. We use the free energy of two consequent amino acids to define a factor for distinguishing flexible regions from the rigid ones. Using statistical analysis of this free energy, we assign a normalized number between zero to one hundred which we call it flexibility number. Taking the effects of up to four neighbors of an amino acid, into account, resulted in an efficient prediction of flexible and rigid regions of a protein.

MaqamateHamidi is a good example of a text, which has emerged out of the previous culture and literature. This book has turned into a broad site in which various texts have been mixed in such a way that it represents an extensive array of genres. The main purpose of this study is the discovery and analysis of the intertexual relations in Maqamate Hamidi. To achieve this aim, we investigated twenty three Maqams in this this book in the light of Gerard Jeant’s Transtexuality Theory. The results indicated that MaqamateHamidi is a good example of intertexuality in a sense that different allusions to the Holy Quran are made, and also Arabaic poetry is extravagantly is used. Moreover, Hamidi’s book is greatly modeled on Hamadani and Harriri’s works, which attest to the intertextual nature and diversity of voices within this book. This intertexuality reinforces the coherence of meaning in this text, which is in line with Gerard Jeant’s Intertexuality Theory.

The dust produced by the electric arc method in the ferrochrome factory contains high amounts of hexavalent chromium, which has a high solubility in water and causes high environmental pollution. The present research has proposed a new method for neutralization of hexavalent chromium present in ferrochrome dust in solution environment by using chemical precipitation method. After checking conventional and non-conventional additives for neutralization by co-precipitation method, Iron sulfate is added to the aforementioned wastewater before release into the environment as a reducing agent of hexavalent chromium to trivalent chromium. Next, calcium sulfate was used as a stable complex forming factor in the system to remove chromium. XRD and XRF analyzes were used to characterize the dust and UV-Visible to determine the amount of chromium removed from the wastewater. The results showed that for 100 g/l of dust dissolved in water, adding 30 g of iron sulfate in the first stage and 20 g of calcium sulfate in the second stage reduces the content of hexavalent chromium from high values to below 10 ppm. Easy, high speed, cheapness and availability of additives are the merits of this method.

Environmental differences and similarities are the driving factor of travel and tourism; The Africa will be one of the main destinations for tourists in the future, with a great variety of tourist attractions, especially natural and historical. Available statistics show this fact well. All this can be a good opportunity to develop relations between Iran and African countries; Therefore, it is necessary to identify and introduce them to formulate strategic plans. Tourism is a suitable field for the development of cooperation, and paying attention to tourism and including it in diplomatic programs and relations will help to expand relations and remove obstacles; Therefore, in diplomatic relations, serious planning for a more detailed understanding of Africa, including its tourism market, should be put on the agenda. The main purpose of this article is to introduce Africa's environmental capabilities in the field of tourism with reference to the continent's plans in this regard and to answer the question of how tourism can be an effective element in the development of relations between countries. The research method is documentary and library studies and referring to statistics and figures related to tourism to provide solutions for the development of bilateral and multilateral cooperation. The general result of the present research shows the absence of a written program from the I.R. Iran for the development of tourism with Africa. A special suggestion in this regard is to prioritize tourism as a phenomenon with socio-cultural, economic and even political dimensions in the macro plans.

Lentiviruses are considered one of the most effective recombinant viruses for gene transfer to mammalian cells and tissues. This study comprises of two essential parts: (1) evaluation of efficiency of protein purification columns in concentration of recombinant lentiviruses, and (2) production of recombinant lentiviruses carrying GDNF coding sequences. In part (1) we co-transfected human embryonic kidney cell line HEK-293T with three lentivirus vectors called transfer (carrying either GFP or Jred), packaging and envelope vectors. After a filtration step, we applied the supernatant from transfected cells to Amicon protein columns for concentration purposes. Centrifugation removed 99% of the supernatant and left behind 500-µl-volume of solution full of virions. We thereby produced a of virus stock. Various dilutions of this stock were added to HEK-293T cells that produced up to 100% infected cells positively expressing transgenes. To examine whether the removed supernatant (overflow) has any trace of infective virus by chance, we also used dilutions of the overflow for infection and observed no sign of eGFP or Jred expression. Given the need for a high-titer virus stock for successful target cell transduction, our results indicate that our filtration method of virus concentration is able to produce high virus titer and is cost-effective and less time consuming than previous methods. In part (2), due to the importance of neurotrophic factor GDNF in differentiation and neuroprotection as well as in therapy of neurodegenerative disorders, we ligated GDNF coding sequence into the lentivirus backbone in the second phase of our study. We applied the same method outlined above to produce high-titer recombinant viruses. Following infection of human astrocytoma cells with this virus stock, we detected 3-fold increase in GDNF mRNA expression using RT-PCR. Lentiviruses carrying GDNF can therefore be generated at high titer using the column method and applied for differentiation and neuroprotection studies.

In spite of their apparent diversity and variety, Arabic and Persian maqamas are unified, which is the result of a common narrative structure. The main purpose of this study is to uncover this common structure. To this end, 124 maqamas including those of Hamadani, Hariri and Hamidi were analyzed based on Vladimir Propp’s morphology theory. The results indicated that Arabic and Persian maqamas are similar to each other in terms of character types and functioning. Moreover, in 31 functions and seven areas, they are in line with Propp’s theory. Such an approach allowed us to investigate all of these 124 maqamas within a single model and to conclude that narrative structure of these maqamas is the result of a single and primary plan, which has been effective in creation of this genre.

Application of Trichoderma species is a harmless method in controlling soil borne plant diseases thus reducing hazardous pesticide use and environmental pollution. Some Trichoderma isolates performing proper inhibitory effect against Fusarium oxysporum f. sp. tuberosi under laboratory and green house conditions were screened against wilt disease of potato caused by this pathogen under field condition in Shahrood Agricultural Research Center, Iran, during 2009-2010. Results of two years field studies indicated that T. virens (T7) followed by T. asperellum (T2) were superior to others in reducing the disease in comparison to infested control. In comparison to Fusarium infested plots, yield was higher in all plots treated with Trichoderma, but highest yields were obtained from plots in which T. virens (T7) and T. asperellum (T2) were involved respectively. It might be stated that isolates of T. virens and T. asperellum are among the effective biocontrol agents against Fusarium wilt disease of potato and can be used as formulated biofungicides in reducing this disease.

In this study, phenolic compounds-coated ZnO@HAP nanocomposite (Ph.ZnO@HAP) was synthesized and used to improve the physical and chemical properties of chitosan hydrogel for biological application. At first, the phenolic compounds were extracted from walnut green hulls. The synthesis of Ph.ZnO@HAP nanocomposite was performed with the assistance of extracted phenols using a hydrothermal method. Chitosan hydrogel was also prepared using NaHCO₃ at 37°C. Hybrid hydrogels based on chitosan and Ph.ZnO@HAP nanocomposite were prepared in a similar way and then characterized by fourier-transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). The antioxidant property, cytotoxicity, and osteogenesis of hybrid hydrogels were measured using DPPH radical scavenging method, MTT, and alkaline phosphatase enzyme assay, respectively. The FTIR spectra, FESEM images, EDX spectrum, and Zeta potential data showed that Ph.ZnO@HAP nanocomposites synthesized successfully with rod-like morphology, phenolic compounds coated on the surface and a negative particle surface charge. The results of DPPH experiment showed that the antioxidant property of the nanocomposite material increased in a concentration-dependent manner. The FESEM images of chitosan hybrid hydrogels with different concentrations of embedded Ph.ZnO@HAP nanocomposite showed that hybrid hydrogels have a more uniform porous structure, compared to the chitosan hydrogel. Moreover, by an increase in the nanocomposite concentration in the structure of hybrid hydrogels, the antioxidant property augmented. The results of the biological studies showed that the cytotoxicity of hybrid hydrogels on osteoblast-like cells (Saos-2) is lower than that of chitosan hydrogel. Also, hybrid hydrogels showed the higher potential in induction of osteogenesis than chitosan hydrogels.
