Abstract

This study investigates the fundamental impact of naming on shaping the ideology of texts, particularly the Quran. It explores how naming, as a foundational linguistic process within the frameworks of Hodge and Kress (1996), Van Leeuwen (2008), and Leslie Jeffries (2010), plays a pivotal role in constructing meaning, establishing identity, and exerting power. The research also examines the naming component within the Quran and its contributions to explaining the underlying worldview of this text. To evaluate hypotheses, this research employs critical discourse analysis. It explores the approaches of Hodge, Kress, Van Leeuwen, and Jeffries regarding the naming component and applies these theories to the Quranic text. The goal is to elucidate the embedded worldview and the Quran's approach to naming. The findings reveal that in Hodge and Kress's view, the naming process is an ideological tool for promoting and solidifying specific beliefs. Conversely, Van Leeuwen perceives naming as an identity process and a means of interaction and meaning construction within social contexts. Jeffries, combining explicit (ideology) and implicit (literary language) elements, considers naming a tool for producing and reproducing ideological discourses. An examination of naming within the Quran indicates that beyond ideological, identity, and linguistic factors, other elements such as the relationship between theme and naming, the priority of content over naming, and the connection between action, process, and structure to naming also influence this process.

Abstract

Research subject:
Methane hydrate reservoirs as an unconventional resource of natural gas can secure demand of energy in the world for many years. Efficient production prom this resources is the subject of concern. CO2-Methane replacement is a novel method for production from naturally occurring methane hydrate deposits such that methane production and CO2 storage take occur simultaneously.
Research approach: In this study a new kinetic model is proposed for CO2-Methane replacement in hydrate structure. This kinetic model is developed based on the mechanism proposed for replacement in the hydrate structure in the presence of excess water in a slurry phase of methane hydrate. According to this mechanism partial breakage of methane hydrate cages, methane-CO2 substitution and formation of CO2 hydrate proceed simultaneously. Methane hydrate dissociation and CO2 hydrate formation kinetic parameters are evaluated experimentally and fitted on polynomials as function of pressure and temperature.
Main results: Evaluation of the effects of pressure and temperature on the replacement efficiency show that higher replacement efficiency is obtained at higher temperatures and lower pressures. It means that replacement kinetic is controlled by methane hydrate dissociation step. Since, higher temperature and lower pressure favor dissociation of methane hydrate. At 278.15 K the replacement efficiency decreased from 15.78 to 8.80 as total pressure increased from 55 bar to 65 bar, at 280.15 K it decreased from 26.98 to 15.91 by decreasing total pressure from 60 bar to 70 bar. At same pressure 60 bar for 280.15 K and 278.15 K the replacement efficiency is 20.96 and 11.59 respectively.

Abstract

This paper studies the concept of metafiction in Charmshir’s play Dastan-e door vaderaz-e safar-e sultan … be diyar-e farang (1998). Metafiction, as a result of an analytical perspective emerged first in modern novels, attempts to challenge the conventional frame of fictional reference to the reality of the external world as it is suggested in literary Realism. In this type of stories, narrative elements such as plot, character, time, and place are no longer representatives of imagined reality, but they in fact reflect a perpetual conflict between art and reality. However, it can be suggested that reality here is subordinated by the referents of the external world. Linguistically, metalanguage and poetic functions of drama would dominate its object language. The story then will be directed toward its narrative elements as well as its own process of creation. Adaptation and meta-historiographyare some of the other features of this style of writing stories which is associated with parody and irony. Charmshir’s play is not really a narrative of the king’s long journey to Europe;rather it is a challenge for the playwright to realize a metafictional probability in form of a postmodern drama. This play is an artwork about the process of building an alternative story and is a new exploration on narrative facts.The elements such as characters, structure, plot, the authority of the narrator, and the style of narrative are no longer the hidden parts of drama in the representation of the story and meaning;in fact, they are the story in itself. The foregrounding of language here is an ironic reference to literary and dramatic texts while it is a fictional device for fabricating history and manipulating data by which the reader expects to receive narrative information. This studyunravels new aspects of narrative structure in Iraniandrama using an analytic-descriptive approach.

Abstract

Research subject:Well-designed plastic foams, with respect to their cell density and cell size, open-or-close cells, and the cell uniformity, compared to their counterpart unfoamed plastic parts, beside of having the advantages of less material consumption, dimensional stability, better processability, and a higher surface quality, they can have superior mechanical and physical properties, including strength to weight, impact strength, thermal and dielectric properties. The temperature distribution in the different zones of the extruder, the qualities and quantities of the nanoparticle additives and their dispersion in the polymer matrix can have significant effect on the mechanical properties of the produced foams by the extruder.
Research approach: In this study, using an extruder, MA-g-polypropylene microcellular foams, containing 3, 7 and 9 wt% of nano-clay particles, were produced under three temperature arrangements on the extruder and the material and the processing effects on the mechanical properties were investigated.  
Main results: The result of this investigation shows that adding of nanoclay improves the mechanical properties of MA-g-PP.s foams. As an example, the results show that the sample with 7 wt% of surface modified nanoclay, owns about 10% higher impact toughness compared to the samples produced without nanoclay. Also for the same samples a rise of about 5% was recorded in Young's modulus. The microstructural studies of the produced foams by scanning electron microscope (SEM) show that adding of nanoclay can result on more foam uniformity and smaller cell size. In this study, the smallest average cell size (87.5 μm) and the lowest density (0.3 g/cm3) were recorded for a sample with 7wt% nanoclay.

Abstract

Induction heating is widely used in metal industry for melting or heating thin slabs in a continuous casting plant. The wide application is based on good efficiency, high production rate and non-polluting conditions. For designing a parallel resonant induction heating system, calculating the capacitance for the resonant circuit is important, because its value affects resonance frequency, output power, power quality factor, heating efficiency and power factor. In this paper, phase controlled rectifier and H-bridge inverter are modeled. Then a method of finding an optimal value for the capacitance under voltage constraint is presented. This value is selected for maximizing output power of an induction heater, while minimizing the power loss of capacitor at the same time. For this purpose, the role of equivalent series resistance in the choice of capacitance value is significantly recognized. In this regard, the heating coil and the load of induction heating are modeled at first, and then the optimal value of capacitance is selected. Finally a complete model of heater and its power is simulated and effectiveness of the proposed method is verified.

Abstract

Accumulation of polyethylene (PE) wastes has become a major environmental problem. The objective of this research was to assess the potential for microbial degradation of sun-treated low-density PE as a natural way to eliminate PE wastes in semi-industrial condition. Low-density polyethylene (LDPE) films were exposed to one month of sun radiation treatment and then cultured with two PE-degrading bacteria (Sphigobacterium moltivorum IRN11 and Delftia tsuruhatensis IRN27) in aerobic bioreactors over 100 days. Weight loss percentage of the PE and the culture pH were measured. Also, Changes in the chemical structure of the LDPE were assessed by FT-IR and surface erosion and microbial layer formation by bacterial activity was observed by Scanning Electron Microscopy. Partial increases in the culture pH were recorded during the incubation period. The weight loss percentage for T-LDPE samples cultured with Sphigobacterium moltivorum IRN11 and Delftia tsuruhatensis IRN27 was 3.31%±0.013 and 3.98%±0.025 in TLDPE samples, respectively, and functional carbonyl-groups in the TLDPE samples decreased significantly due to bacterial hydrolysis. SEM images showed the different microbial layer formation on sun-treated low-density polyethylene (T-LDPE) for both bacteria. Our results suggest that exposure of LDPE to sun radiation had a significant effect on biodegradation of Ld-PE films and that the two bacteria tested were able to enhance the biodegradation the T-LDPE.

Abstract

To improve the behavior of building structures subjected to lateral loads, such as wind and earthquake excitations, tuned mass damper (TMD) has been used extensively theoretically and experimentally in previous researches. To increase the effectiveness of TMD mechanism, different methods have been proposed to determine the optimal values of TMD parameters including its mass, stiffness and damping. In using single TMD on the structures subjected to external vibrations, the mistuning of TMD, variation of TMD damping and changes in structural dynamic characteristics cause significant reduction in the effectiveness of TMD. Multiple tuned mass dampers (MTMDs) have been proposed to overcome the shortcomings of single TMD where each TMD has different dynamic characteristics. Based on the results of different researches, it has been concluded that the performance of MTMDs is less sensitive to uncertainty of structural dynamic parameters than that of a single TMD. In the previous researches, for designing MTMDs on the linear structures subjected to various external excitations, several methods have been proposed based on different kinds of design criteria. In most of the proposed methods, to simplify the design procedure of MTMDs, some limitations such as identical masses and damping ratios for TMDs or uniform distribution for the frequency or damping of TMDs have been considered. Also these methods require extensive numerical analysis. To generalize the design problem of MTMDs, in this paper, an effective method has been proposed for optimal design of MTMDs on the multi-degree-offreedom linear structures subjected to any desired excitation. In this method, an optimization problem is defined for designing the optimal MTMDs. The minimization of the maximum displacement of structure is considered as objective function and the parameters of TMDs are considered as variables. Since the design problem includes a large number of variables, hence, in this paper, it has been decided to use Genetic Algorithm (GA) for solving the optimization problem. To illustrate the procedure of the proposed method and also to assess the effectiveness of MTMDs in improving the seismic behavior of structures, a ten–storey linear shear building frame was subjected to white noise excitation and for different values of TMDs mass ratio and TMDs number, optimal MTMDs were designed for minimizing the maximum displacement of structure. To focus on the main objective of this paper and avoid the complexity of the problem, TMDs were located on the top floor in parallel configuration. The results of numerical simulations showed the capability of GA in solving complex MTMDsdesign problem with a large number of variables as well as the simplicity of the method under any desired external excitation. Also it was concluded that increasing of the mass ratio of TMDs could improve the effectiveness of MTMDs. To assess the performance of optimal MTMDs under other earthquakes, which are different in characteristics with design record, optimal structure-MTMDs was tested under near-fault and far-fault earthquakes and the results have been reported.

Abstract

Criticism of new historicism has been formed in opposition to traditional historicism. Contrary to traditional historicism, which speaks of the one-sided influence of history on literature, new historicism believes in the mutual influence of literature and history on each other. The story of Bahram and Golandam is one of the remarkable poems in Kurdish literature, which are called "Beit". Beits are syllable-weighted folktales recited by beit readers. It can be said that there are some similarities between the stories of Bahram and Golandam and Zal and Rudabeh. Therefore, it is possible to measure these two stories with each other. In this research, relying on library and documentary studies and with an analytical-comparative approach, we have tried to give a reading of the two stories in question based on the concepts of new historicism. The findings show that although both stories are apparently romantic and the conflicts are about love and marriage; But inside the story, power and discourse interests are fundamental issues. Every discourse tries to maintain its political and social interests.

Abstract

In recent decades, as the result of the expansion of industrial life, fast foods  and fried foods consumption has increased significantly. Consumption of fried foods including saturated fat and trans fatty acids is one of the important factors which endangers human health and the risk of heart disease, weight gain, cancer. With increasing consumer awareness of the health effects of dietary fat, tend to produce low-fat food consumption is increasing. Nowadays, the main challenge is to enhance the frying process by controlling and lowering the final fat frying of the fried foods. In this study the effect of microwave pretreatment levels 360, 600 and 900 W), on moisture and oil content, color and hardness of fried zucchini at three temperatures, 130, 160 and 180 ° C were studied. The results showed that the moisture content decreased with increasing frying time and oil hardening rate increases. The moisture content with increasing frying temperature is reduced and the amount of oil absorption is reduced. The highest oil uptake in control samples, and the lowest in samples treated with microwave 900W was observed respectively.

Abstract

Fried foods are favored by consumers because of the crispy crust, desired flavor and color, but these properties are accompanied by some undesirable effects to the consumers due to the considerable amount of oil absorption during frying process. Nowadays, the main challenge is to enhance the frying process by controlling and lowering the final fat frying of the fried foods. In this study, the effect of hydrocolloids (methyl cellulose, pectin and methyl cellulose- pectin) on the quality of deep- fat fried Falafels at 150, 170 and 190 ˚C for 1, 2, 3, 4, and 5 min were evaluated. Moisture content decreased whereas oil content, hardness, volume and color of potatoes increased with increasing fried time, fried temperature. The lowest oil content values are given for samples coated with methyl cellulose- pectin. The control samples had the highest percentage of fat content in all the frying time range.

Abstract

Raisin is a principal traditional export product of Iran and has occupied a special position in the foreign trade of the country. During storage period, the product turns sticky and hard due to exudates syrup and moisture loss. To overcome this problem the application of edible coating suggests being of proper assistance. Edible coating may enhance the boundary layer resistance resulting enhanced shelf life of product. In this research the method of Accelerated Shelf Life Testing (ASLT) used for evaluation of storage and sensory properties (texture, colorو taste and overall acceptability) of raisin .Raisin was treated with coating materials based on lipid (glyceryl monoestearate and carnauba wax) with 150 ppm essential oil of thyme (thymus vulgaris) and stored at 20, 35 and 50oC for 12 weeks. During this period of storage sensory properties were evaluated and estimate the modeling shelf life of raisin. Results showed that coating, affect on texture and color significantly and caused increasing shelf life of raisin. Temperature and storage time also showed significant effects on total sensory attributes. Maximum shelf life (394 days) determined at 20 oC for carnauba wax coating with essential oil of thyme based on overall acceptability   and linear regression and second order function had best fit with R2≥0.94 for all of treatments.

Abstract

Ventricular Fibrillation (VF) is the major cause of triggering sudden cardiac death (SCD). Efficient prediction of ventricular fibrillation is very important for clinical purpose, as this is the most serious cardiac rhythm disturbance and can be life threatening. A reliable predictor of an imminent episode of VF, could be incorporated in an implantable cardioverter defibrillator (ICD) would be capable of delivering preventive therapy. The aim of this study is to investigate the possibility of predicting VF from surface electrocardiogram (ECG) signal by beat to beat tracing of the signal and using a dynamic thresholding method. As VF arises from the lower pumping chambers of the heart (ventricles), it is expected to find some changes in the ventricular activity part of the ECG signal before its occurrence. In this paper, we focused on the T-wave of ECG signal which shows the repolarization of ventricles and tried to present an online predictor by finding an entropy-based pattern in T-waves of ECG signal that can effectively maps the irregularity of this wave before VF. We have also used an Empirical Mode Decomposition (EMD) method to reduce the high frequency noises of T-waves before predictive index extraction in each beat. We found that proposed predictive pattern can be considered as a useful index for probability occurrence of VF. It reached the sensitivity of 89% and specificity of 95% in online VF prediction method. Presented method is simple, computationally fast and has high prediction quality and hence is well suited for real time implementation.

Abstract


In this study, a comprehensive assessment of the occurrence and spatial distribution of heavy metals including Nickel, Lead, Zinc, Copper, Cadmium and Chromium, as well as, TPHs in the surface sediments of the coastal areas and far from the coast of the Persian Gulf in Bushehr and Khuzestan provinces were performed to identify the possible sources of sediment contamination and determining the degree of pollution. Eight pollution indices were used to evaluate the quality of sediments in terms of heavy metal and TPH pollution. The investigated areas could be distinguished by a significant degree of heavy metal pollution of Nickel, Cadmium and Zinc. High concentrations of Nickel and Zinc were observed in stations around Nakhiloo, Bushehr. The comparison of average pollution indices between regions showed that both Bushehr and Khuzestan provinces, respectively, with the average of contamination degree (CD) (20.25 and 22.11), modified contamination degree (MCD) (3.38 and 3.69), pollution load index (PLI) (31.17 and 57.57), potential ecological risk index (PERI) (353.54 and 349.39) have a significant degree and risk of Nickel and Cadmium pollution, especially in Nakhiloo area, Bushehr. Investigating the spatial fluctuations of the concentration of TPHs in two provinces showed an increasing trend from Bushehr to Khuzestan. However, areas were located in no pollution or low pollution zonation and were safe from the adverse biological effects of TPHs. Comprehensive and impressive strategies to control and reduce these pollutions, especially in polluted areas, should be considered, so that the sources of these pollutions be managed.

Abstract

These days biosensors have worthy applications in different fields such as biomedicine, disease diagnosis, treatment monitoring, various aspects of the environment, food control, drug production, and assorted sides of medical science. Recently, different types of biosensors such as enzyme biosensors, immune, tissue, DNA, and thermal biosensors have been studied precisely by some research groups. These biosensors have many advantages such as simplicity in implementation, very high sensitivity, automatic performance, intrinsic and natural small size. Another valuable benefit of biosensors is that their high-affinity paring with biomolecules allows sensitive (high-sensitivity) and selective detection from a wide range of analytes. Artificial intelligence (AI) due to its high potency, if combined with biotechnology, like biosensors, can be effective in accurate prediction, diagnosis and treatment of some diseases, including cancer. Today, Machine learning (ML) as one of the branches of AI has become a beneficial tool in analyzing and categorizing obtained data from biosensors for bioanalysis. Using ML algorithms automates the complicated processes of extraction, processing, and assaying data achieved from biosensors. This article is a review for introducing and survey of various biosensors, their applications, and ways to apply them, focusing on cancer and Covid19 which are important diseases in the world obtained from previous studies, as a summary and providing information for researchers which working in this field.
