Abstract
By bringing up the category of paratextuality, Gerard Genet was able to push the boundaries of the analysis and study the image on the book cover to semiotic opinions in order to recognize the semantic layers of the design on the book cover. Mohammad Taimur wrote the first collection of short stories of the Arab society under the title "Ma Ttrah Al-Ayoun". Now the problem is that the semantic connection and coherence of the design on the cover of the book "Ma Trah Al-Ayoun" with evaluation of semiotics to what extent makes the paratextual capability of the design smooth with the content of the book. The current research aims to analyze the layers and symbolic components of the cover design of the book "M Trah Al-Ayoun" as the paratext of the book, in order to understand the semantic and communication layers of the cover design of the book with the internal text and secondary goals of the author and in this regard, used the descriptive-analytical method with the approach of visual semiotics. The results indicate that the paratext of the design on the cover the book with the use of colors, which are the most prominent functional component of the design, the use of the shape of the eye and the broken lines behind the eye and the use of letter "M" and "A" connected to "M" was able to reflect the title of the book and experiences of the author should be parallel to the internal text.

Abstract
Cucumber root and stem rot disease caused by Fusarium oxysporum f. sp. radicis-cucumerinum (Forc) is one of the most important diseases of cucumber in Iran. In this regard, this study aimed to investigate the antifungal activity of some chemical salts against Forc in in vitro and greenhouse conditions. The experiment layout in the in vitro condition was based on a factorial experiment using a completely randomized design including three replications. Treatments included potassium sorbate (PS), mono-potassium phosphite, ammonium bicarbonate, salicylic acid (SA), di-potassium hydrogen phosphate (DPHP), and fungicide carbendazim (CAR) (Bavistin WP 60%) at 0, 0.5, 2, 4, and 5 g/l. In a greenhouse condition, the experiment was conducted using a randomized complete block design with three replications. The laboratory and greenhouse experiments showed that the treatments had a significant effect on fungal growth inhibition and disease severity. In in vitro condition, the highest control of the fungus was attributed to PS and fungicide CAR. Conversely, DPHP had the least control (8.74%) on the growth of Forc at 0.5 g/l. In a greenhouse condition, CAR prevented disease symptoms for one month. However, PS and SA controlled mycelial growth with an efficiency of 61.19 and 39.2%, respectively. Accordingly, it seems that PS and SA are fungitoxic against Forc and can control root and stem rot disease in the greenhouse by root and foliar application.

Aims: The identification of factors that affect health literacy in the elderly will aid in designing interventions aimed at promoting health literacy by focusing on these factors. Therefore, the present aimed to determine the relationship between health literacy and financial literacy among the elderly.
Instrument & Methods: This cross-sectional study was conducted on 295 elderly in Urmia, Iran, who were selected using a multi-stage cluster sampling method in 2022. The data collection tools included a demographic information form, the Health Literacy for Iranian Adults Questionnaire, and the Financial Literacy Questionnaire. Data were analyzed using SPSS version 16, employing the Kolmogorov-Smirnov test, independent t-test, one-way ANOVA, and Pearson correlation coefficient.
Findings: The mean health literacy score of the elderly participants was 64.38 out of 100, indicating a not very sufficient level. Additionally, the mean financial literacy score was 47.84 out of 100, reflecting a low level of financial literacy. A positive and significant correlation was found between financial literacy and health literacy (p<0.001, r=0.60).
Conclusion: There are low levels of both financial literacy and health literacy among the elderly in Urmia, and financial literacy and health literacy are positively correlated.

Abstract
Objectives: Long non-coding RNAs (lncRNAs), a vast class of recently discovered non-coding genes in the human genome, have been implicated in the regulation of several biological processes, including the maintenance of stem cell pluripotency and neurogenesis. New evidences have emerged that some long IncRNAs act as enhancers for their neighboring genes. Oct4, also known as POU5F1 and Oct3/4, functions as a master regulator in maintaining the properties of pluripotency and self-renewal of embryonic stem (ES) cells and embryonal carcinoma (EC) cells. Oct-4 expression must be tightly regulated; too much or too little expression can lead to cell differentiation. Methods: PSORS1C3, an IncRNA, is located upstream of the Oct4 gene. This IncRNA could potentially impact the level of Oct4 expression. Here, we have investigated potential expression of PSORS1C3 on 23 different human pluripotent and cancer cell lines by means of RT-PCR. Results: Our results revealed a noticeable expression of PSORS1C3 both in a well-known pluripotent cell line (NTera2/NT2) and five different cancer cell lines (AGS, 5637, Ht-29, HepG2 and PC3). Conclusion: We detected the expression of PSORS1C3 for the first time in both cancer cell lines and stem cells.

Abstract
In recent years, electrospinning that has the capability to form polymeric nano-/microfibers has gained substantial attention for fabrication of tissue engineering scaffolds. The morphological resemblance to native extracellular matrix (ECM), high surface to volume ratio, high porosity, and pore interconnectivity are amongst the brilliant features of electrospun structures. The high surface area to volume ratio and interconnected pores of these fibrous meshes confer desirable cell attachment and growth. However, due to small pore sizes and high packing density of electrospun nanofibers, cell penetration into a conventional electrospun mat is completely restrained. Scarce cell infiltration in turn prohibit cell migration into internal parts of the scaffold, cause inhomogeneous cell distribution throughout the structure, limit vascularization, and impede tissue ingrowth. In fact, traditional electrospun nanofibrous scaffolds in practice act as two-dimensional (2D) surfaces rather than three-dimensional (3D) microenvironments. Thus far, a number of approaches have been employed to solve this problem, which range from simple variations in electrospinning parameters to intricate post-processing modifications. Some efforts directly manipulate the electrospun mat characteristics to enhance cell penetration, while others combine cells with scaffolds or encourage cells to migrate into internal parts with different stimuli. In the present study, we have attempted to provide an overview of different approaches offered for improving cell infiltration in electrospun scaffolds.

Abstract
Due to the importance of tumbling mills in processing industries and factories and the lack of an acceptable model for identifying and predicting their performance, it is necessary to optimize these complexes, non-linear, and large systems. This paper aimed to study multi-objective optimization of operating parameters in a tumbling mill. To evaluate the effects of the mill working parameters such as mill speed, ball filling, slurry concentration, and slurry filling on grinding process, power draw, wear of lifters and size distribution of the mill product, it was tried to manufacture a pilot model with a smaller size than the actual mill. For this aim, a mill with 1×0.5m was implemented. The feed of the mill is copper ore with a size smaller than 1 inch. The experiments were done at 65 to 85% of the critical speed. In addition, the combination of the balls was used as grinding media with 10 to 30% of the total volume of the mill. Slurry concentration is 40 to 80% (the weight fraction of solid in slurry) and the slurry filling is between 0.5 and 2.5. In this paper, Adaptive Neuro-Fuzzy Inference System (ANFIS) based multi-objective optimization (NSGA-II) of tumbling mill is done. Level diagrams are used to select the best solution from the Pareto front. The results showed that the best grinding occurs at 70-80% of the critical speed and ball filling of 15-20%. Optimized grinding was observed when the slurry volume is 1-1.5 times of the ball bed voidage volume and the slurry concentration is between 60 and 70%.

Abstract
Population growth and loss of environmental capacities for food production have rendered the realization of food security a more complicated task as compared to the previous decades. To cope with this crisis, sustainable agricultural development can play a remarkable role in improving food security. The present study aimed to explore the spatial effects of agricultural sustainability on food security of rural households in 30 provinces of Iran over the period of 2006-2016. For this purpose, first, the overall level of agricultural sustainability using a Composite Sustainable Agriculture Index (ICSA) and weighting indicators were calculated based on Analytic Hierarchy Process (AHP) method. The Aggregate Household Food Security Index (AHFSI) was used to determine the food security of households in rural areas. Also, the effectiveness of agricultural sustainability on food security of rural families, as well as other effective factors, was examined using the mixed Spatial Autoregressive (SAR) model with panel data. Results show that the spatial spillovers of the agricultural sustainability influence food security positively and significantly. In fact, 1% increase in the agricultural sustainability index of a certain province directly improves food security of the same province by 0.043%, while its food security is indirectly enhanced by 0.0131% with 1% increase in the agricultural sustainability index of other provinces. It is imperative for policymakers of the agricultural sector to invest in production infrastructure of different provinces in Iran and focus on enhancing sustainable production as a prerequisite for the establishment of sustainable food security.
