Abstract
This study aimed to evaluate the capability of the halophyte A. littoralis in symbiosis with Rhizophagus intraradices and Nocardia Halotolerans an indigenous bacterium of saline soils- on phytoextraction of Na under saline conditions. Salinity treatments included 0 (S0), 100 mM NaCl (S1), 200 mM NaCl (S2), 100 mM NaCl+50mM K2SO4 (S3), 200 mM NaCl+50mM K2SO4 (S4) levels. Plant fresh and dry weight, chlorophyll content decreased as salinity increased up to S2 level and increased thereafter. Plant root colonization in the inoculation and co-inoculation of AMF+SR-PGPB were similar. Compared to the S0 treatment, root colonization in the AMF group decreased by 23.5%, 32.6%, 13.5%, and 26.7% under S1, S2, S3, and S4 treatments, respectively. In the Bacteria+AMF group, the reduction was smaller, with decreases of 2.8%, 3.4%, and an increase of 6.8% and 1.4% under S1, S2, S3, and S4 treatments, respectively. These results indicate that co-inoculation with PGPB mitigated the negative effects of salinity on root colonization. The root and soil glomalin contents increased as salinity increased. Root glomalin in plants inoculated by AMF+SR-PGPB was more than in a single inoculation of AMF under salt stress. This study highlights the potential application of salt-tolerant bacteria and AMF as effective strategies for enhancing plant growth and productivity in saline environments, contributing to sustainable agricultural practices in affected regions.

Abstract
As climate change intensifies the frequency and severity of droughts, adaptive behavior becomes increasingly crucial. Farmers' capacity to modify their practices in response to evolving climate conditions is vital for ensuring long-term agricultural sustainability and food security. Therefore, this study aims to investigate the psychological factors affecting farmers' adaptation behaviors in response to drought, using the health belief model. The sample comprised 380 farmers from Kohdashat County in Lorestan Province, western Iran, selected via a three-stage cluster sampling method. Data were collected using a researcher-designed questionnaire, whose validity and reliability were confirmed. Structural equation modeling (SEM) results indicated that self-efficacy; perceived benefits, perceived vulnerability, and perceived barriers explained about 49% of the variance in farmers’ adaptation behavior. Perceived benefits emerged as the strongest predictor of adaptation, while cues to action and perceived severity were insignificant. These findings support the health belief model's practicality and effectiveness in examining water conservation behavior among Iranian farmers.

Abstract
Aims: Most of the world population who is at work and production age does not have appropriate and regular physical activity for various reasons. Accordingly, the researchers tried to evaluate the effect of physical activity predictors of employees through the path analysis based on the Pender's Health Promotion Model (HPM). Methods and Materials: We conducted this study on 359 employees of the milk and milk powder production factories in Mashhad. A questionnaire consisted of items related to the structure of the Pender's Health Promotion Model (Perceived Benefits, Perceived Barriers, Prior Related Behavior, Perceived Self-Efficacy, Activity Related Affect, Personal Factors, Interpersonal Influences and Situational Influences) and the IPAQ standard questionnaire related to the physical activity were designed and applied in interviews as data collection instruments. Findings: One fourth of the employees had proper physical activity. Generally, structures of the Pender's Health Promotion Model predicted 34.8 % of the physical activity behavior variance. Regression analysis has shown that the predictability of Prior Related Behavior, Perceived Self-Efficacy, Personal Factors, Activity Related Affect and Interpersonal Influences are significant and Situational Influences are nearly significant. Prior Related Behavior (β = 0.45, P < 0.000) and Self-Efficacy (β = 0.17, PConclusions: The findings of the study revealed that HPM is efficient in identifying and predicting the physical activity behavior. This pattern can be used as a framework for planning and implementing educational interventions in order to improve the physical activity of the adult employees.

Abstract
Aim: Breast cancer is the most common cancer among women worldwide. This comparative study was designed to investigate the knowledge, attitude, and practice of medical and non-medical female students concerning breast self-examination (BSE) in two different universities in Shiraz, Iran. It also examined the relationship between the students' knowledge, attitude, practice and type of academic education. Methods: A cross-sectional survey was conducted in Shiraz, Iran. 394 female students were selected using proportionate stratified random sampling (292 non-medical and 102 medical). A self-administered questionnaire was used for data collection, and the obtained data were analyzed descriptively. Findings: Medical students were more aware of BSE timing, stages of BSE performance and initiation age of BSE. Medical female students were also more likely to consider BSE as efficient, not difficult and time consuming, and to acknowledge that as a method for decreasing the probability of cancer. Regular BSE performance rate for both groups was very low and unsatisfactory (non-medical 2.1% and medical 2.9%). The results of t-test and Chi-square revealed significant differences across BSE knowledge, attitude and practice with type of academic education (medical or non-medical) (P=001). Conclusion: Based on the findings, the medical students were more knowledgeable and showed a better attitude and responded more positively than the non-medical student, but both groups showed low level of BSE practicing that is of a concern. The supportive role of universities in providing students with necessary information about breast cancer is suggested, and its prevention methods should be highlighted. Additionally, there is a need to a supportive environment which facilitates students’ access to qualified health care services.

Abstract
This study aimed to provide a model for improving the quality of women's and girls' leisure time in the family with an approach based on physical activity in Isfahan province. This research was carried out using a qualitative method with a systematic approach of grounded theory. The theoretical population consisted of knowledgeable and experienced women's sports and leisure professors who also used the snowball method for sampling. The data collection tool and method were semi-structured individual interviews, and the interviews continued until the theoretical saturation of 15 interviews. For data analysis, a systematic approach includes three main steps: open coding, axial coding and selective coding. In the axial coding stage, the connection between the following categories of causal conditions (support of important others, organizing, applicability of activities, institutionalization of activities); context factors (environmental attractions, environmental conditions, sports attractions(; interfering factors (evolutionary changes, cultural and social barriers, gender hegemony, macro trends, structural barriers); strategies (education and culture building, measures to support women's recreational sports, promotion and development of physical activities, respect for the dignity of women and girls, justice in the implementation of activities, media support) and consequences of qualifying women's leisure time (reducing behavioral disorders, individual empowerment, collective empowerment, increasing participation) in terms of coding paradigm in Sports manufacturing corporations was determined; also in selective coding phases, each component of coding paradigm described. The province's sports managers can use the signs, concepts and categories identified in their plans to improve the leisure time of women and girls in the family with an approach based on physical activity and use the proposed appropriate strategies to compensate for the backwardness and development of women's sports.

Abstract
Water erosion causes a series of on-site as well as off-site damages and problems on natural ecosystem. These damages include soil and nutrient loss and finally loss of productivity which causes costs to the society. So, this study attempts to quantify the economic value of soil productivity conservation as one of the important functions of rangelands vegetation and its economic cost by productivity losses. The soil loss amounts were obtained from integrated Geographic Information System (GIS) and map of erosion vulnerable areas using RUSLE model. Supplementary data such as soil nutrients (NPK) valuated from the measurement plots of a portable rainfall simulator (E65). Field plots were constructed to measure soil nutrients and soil loss from different soil types with different resistance to erosion. Rainfall simulation was carried out in three sites on the basis of geology map and different resistance to erosion. Nine experimental unit plots (1*1 m) were used to correlate nutrient loss to sediment losses. Assuming that nutrient loss by erosion could be replaced by fertilizers, economic cost of major nutrients estimated by market prices of fertilizers. Results showed that mean annual soil loss using RUSLE was 27.44 t ha-1 y-1 ranging from 0.0 to 996.06 t ha-1 y-1. Also, 114.17 kg ha-1 y-1 of N, P, K elements were lost in 2010 due to soil erosion in the degraded rangelands which costs (738944 Rial) 71.5 US$ ha-1y-1. Total economic cost of soil nutrient loss in 94978.6 ha of the rangelands of Nour-rud watershed basin, was estimated 70×10^9 Rial (6.8×106 US$). The maximum annual cost of soil nutrient loss was estimated in the "TRujs" geological formation (1.23×106 US$) consisting of "gray shale, silt, sandstone, conglomerate" and the least cost belonged to the "Jl1" geological formation (0.916*106 US$) which consists of "thin gray dolomite limestone". In economic terms there was a direct relationship between soil nutrient loss and its economic cost.

Abstract
Aims: How to design spaces in cities can have different effects on citizens. The objectives of this study can be to examine the impact of biophilic urban space on the stress of people.
Methods: The research method is quasi-experimental. The statistical population of the study consists of 20 bachelor and master students in the field of architecture and urban planning at Tabriz University of Islamic Arts in the academic year 1400. First, students' health was identified using a call announcement and a demographic questionnaire, and these individuals were quantified for stress with the help of a smart wristband while viewing images of biophilic and non-biophilic urban spaces with the help of virtual reality glasses.
Findings: Analysis of the results shows that the average change in stress of individuals while viewing non-biophilic images was approximately 5/2 units higher than biophilic ones in the second minute. p-Value is significant between individuals with education in biophilic state and rest in 1 minute and non-biophilic in 2 minutes. The difference between stress number in non-biophilic state and biophilic in 2 minutes is significant (p-value = 023/0) and shows the positive effect of biophilic approach on reducing stress that this efficiency can be considered in the design of future urban spaces.
Conclusion: Special attention of urban designers on the structure of spaces and the use of extraction measures from the biophilic model in different scales cause the design or organization of spaces that significantly reduce the stress of people living in cities

Abstract
The runoff generation and soil erosion in the Kechik Watershed, Golestan Province, was assessed, using a designed and constructed portable rainfall simulator. Treatments were applied on different land-uses, slopes and aspects as the most influential factors. Results showed that land-use significantly affected runoff generation (13.35 l, 6.9 l, and 4.12 l, respectively for agriculture, forest and rangeland uses), however slope (7.7 l for Class I; 9.23 l for Class II) and aspect (8.52 l for the northern aspects; 8.32 l for the southern aspects) did not have significant influence. All factors, significantly altered sediment concentration (Agriculture 9.6 g l-1, forest 8.24 g l-1, and rangeland 5.26 g l-1; slope class I 6.6 g l-1 and slope class II 8.7 g l-1; northern aspect 8.7 g l-1, and southern aspect 6.9 g l-1). Agricultural fields generated the highest runoff and sediment under simulated rainfalls. Rangeland and forest did not have significant runoff generation and sediment concentration. Results showed that land-use management, especially in terms of agriculture, could not only hamper current erosion, but reduced further advancement of this encroaching phenomenon.

Abstract
This study tries to make a distinction between factors affecting adopters and non-adopters of domestic rainwater harvesting (DRWH) in Golestan Province, Iran. In order to better comprehend the differences, nine dimensions were considered in this study, including (1) social background (including respondents’ demographics, water sources, issues in accessing water sources, primary awareness of the DRWH systems, information communication channels, and their dwellings characteristics), (2) economic and financial scale (including construction, maintenance, investment rate of return), (3) scale (including law and regulation) (4) social scale (effect of social determiners on person’s decision making), (5) compliance with every day’s needs,(6) past experience, (7) image (importance of adopting DRWH systems on person’s social image and position), (8) providence (person’s outlook of the future), and (9) risk adoption. Results show that the surveyed groups vary remarkably in terms of considered dimensions. It seems that lack of experience and observation are the underlying reason of low adoption rate in this area.

Abstract
MeHg and total mercury concentrations were determined in the muscle tissues of four fish species (Cyprinus carpio, Rutilus frisii, Carassius auratus and Esox lucius) from Anzali wetland (Guilan, Iran). Fish with the highest amount of MeHg was selected to determine the thermodynamic parameters of MeHg extraction. The extractions process was performed in the range of temperatures 331.15 to 367.15 K and at atmospheric pressure. Results show the extraction of MeHg from SH groups of sulfhydryl proteins was an endothermic process with a positive value for entropy and Gibbs free energy changes at the room temperature. Significant difference was found between MeHg content at T=367.15 K and other temperatures. Correlation coefficients results showed that the mercury concentration in muscle tissue was significantly related to the length and weight of fish (p≤0.01). Also, thermodynamic parameters of methylmercury extractions had significant correlation (p≤0.05) with length and weight of the six fish specimen.

Abstract
The optimal cropping pattern for Sistan water resources management was determined through a goal programming technique within the GAMS programming environment. Results showed that the optimum cultivation area and net profit of the agricultural sector in the Sistan region could increase up to 18.1 and 39.8%, respectively, compared to the current status. An increase in the farm irrigation efficiency from the current 35 to 55% would increase the net profit of the agricultural sector by 49.7% despite 6.4% reduction in water consumption. At the same time, 20% increase in the efficiency of water delivery system to farmlands would lead to 8.2 and 17.2% increases in the cultivation area and net profit, respectively. The results of combining these two management scenarios indicated that farming net profit would increase by 64.3%, while total water consumption in agricultural sector would decrease by 2.3%. Under wet condition, cultivated area and net profit would respectively increase about 32 and 44%. However, upon drought years, the cultivated area and net profit would experience 86.9 and 87.3% loss, respectively.

Abstract
The optimal allocation of the Chahnimeh water resources among different sectors, viz. domestic, agricultural and environmental consumptions, was determined using the goal programming method in GAMS, based on the present condition in the area. Results showed an increase of 15.4, 44.5 and 230% in allocation of water to domestic, agriculture and environment sectors, respectively, in this method as compared to the present allocation. Besides, implementation of the second water transferring line to Zahedan city would resultin a 66% increase in the water transferring rate to this city without any change in water supply for domestic sector in Zabol city and the surrounding villages. The scenario of 20% reduction in water per capita consumption led to about 5.9 million cubic meters saving in water supply from Chahnimeh reservoirs to the domestic sector. According to the projected population growth for 2025 in the study area, water consumption in domestic sector will increase by 15.9%. Results showed that the goal programming can be applied as a useful tool to analyze the effect of different scenarios on water demand and supply management and, hence, to allocate water for different sectors in a most appropriate way.

Introduction
Media literacy leads to public rights discourse. The discourse of public law is effective in monitoring the government through the qualitative and quantitative expansion of the demanding element. People are more persistent in insisting on the rights they are sure they have the right to have. In all societies, the interested people with the power of influence in the field of media turn society into an unequal campaign. The way to deal with this is to expand the right to media literacy. In addition, in advertisements that aim to show reality and distort it deliberately and biasedly, if the audience does not have enough knowledge and is deprived of many sources to benefit from information, it will not result in a distortion of reality or an inorganic change of public opinion. The action of the government in promoting media literacy, in addition to fulfilling one of the human rights, is a smart action that is effective in the field of public participation. If citizens benefit from the right to media literacy, we are faced with a controlling power that relies on collective wisdom. The present article is trying to find a universal solution through theory in order to have a micro-oriented government by relying on the processing citizens.
Methodology
The method of carrying out library research is analytical-descriptive. In this regard, in order to answer the questions and test the assumptions, the method of content analysis has been used.
The information has been collected by the library method and by extracting vouchers from reliable sources. After collecting information and laws in the fields of freedom of expression, freedom of information, media rights, public opinion and the right to education, the issue has been analyzed. In order to benefit from the role of interactive media, attention has been paid to the recent laws of the parliament and the amount of use of keywords related to those laws in the virtual space before they were approved in the public forum of the parliament. The findings indicate the approval of some recent laws based on public opinion, especially regarding the country's annual budget. The statistical population considered for the research is the Islamic Republic of Iran. Although, the ideas of researchers from other countries and other legal systems have also been used,
Results and discussion

Media literacy guarantees the exchange of correct information and rational media filtering by using public wisdom. Media literacy significantly reduces the level of political indifference, a crisis facing modern society. The level of sudden arousal of motions by the media is less observed in societies that have a favorable level of media literacy. In addition to monitoring the government's power, increasing media literacy will increase the psychological security of society. The prerequisites for mastering the skill of selection are awareness and freedom. Strengthening and understanding the world
of life by guaranteeing fundamental rights lead to the evolutionary evaluation of justice by citizens. The supervisory function of interactive media plays a critical role in increasing responsibility and accountability in various social fields.
The regulatory role of the media is directly related to the recognition and guarantee of the public domain. The government is obliged to protect the public domain. The exchange of information in the public sphere is considered a part of the new freedoms and the continuation of the right to freedom of expression. People are trying to achieve mutual understanding in their interactions, and the active and interpretive presence of elites in the public domain plays a key role in promoting media literacy. In interactive media, where it is possible to benefit from collective wisdom through public opinion, and in social media, where content is produced by the public, it finds symmetry with Habermas' concept of the world of life. The active presence of citizens in the public domain requires guaranteeing freedom of expression and the right to access information. In this regard, changes in the laws related to the right to teach media literacy are inevitable.
Conclusions
In the modern government, with the development and growth of the media, the need for media literacy has become an inseparable part of the lives of the citizens of the modern government. The government is obliged to continuously review the laws and regulations in line with media innovations and create the evolutionary course of society through deregulation and policymaking based on needs. The power of cognition, the power of judgment, and data analysis are the fundamental foundations of media literacy education. Media literacy provides the power of understanding, the power of judgment, and the possibility of participating in collective discussions. In modern government, media literacy is the most important platform for the formation of the public sphere. By improving media literacy, the level of conscious participation improves. The public pays more attention to public domain issues.
Operational solution: knowing the laws related to the theoretical field and making demands is based on the principle of the rule of law.

Abstract
The issue of job absenteeism as a critical factor for organizations brings significant financial losses. The absence is one of the all-consuming challenging and time consuming problems organizations could face and in economic point of view, one of the factors increasing the cost of production. These issues are more common in estate owned organizations. Given the need to identify causes of absenteeism and staff desertion, this study, with scientific and realistic analysis on the causes of absenteeism, try to find solutions and ways to overcome these issues. Reviewing experiences of some management scientists and sociologists, Q-methodology used to identify important factors causing employees absenteeism which those factors were finalizing using factor analysis. Statistical population was staff of the case study where three of the specialists interviewed, 40 Q identified and prioritized by the participants. 5 factors were identified, which collectively illustrate the importance of performance-based pay, developing systematic indicators to evaluate performance, enriching jobs by redefining the identity, awareness and transparency in the formulation and implementation of organizational structure.

Abstract
The toxicity of garlic is confirmed on some agricultural pests. The aim of this study was to comparatively evaluate the sensitivity of
Podisus maculiventris (Say) to garlic extract and two insect pests:
Mediterranean flour moth Ephestia kuehniella (Zeller) and Colorado potato beetle
Leptinotarsa decemlineata (Say). LC
50 was calculated at 8.02% for
E. kuehniella. The results showed toxic compounds in garlic extract delayed all developmental stages and reproduction parameters of
L. decemlineata. In contrast, there were no considerable negative effects on many of the biological parameters of the predatory insect,
P. maculiventris. The results suggest that garlic, as a green pesticide, could be considered an environmentally suitable alternative in pest management programs.

Abstract
Since the beginning of emergence of Pakistan as an independent country, the conflict about Islamic state had begun between the secular and religious groups. “What is the role of Islam in the government?” was the question that Pakistan was facing in the last decades of 20th century. In response to the question, Muslim scholars proposed two answers: the first group suppose that Islam is equal to government and second group believe that the government in Islam has only one dimension and other dimensions of Islam are much more important than political dimension. .Ghamidi with passing from the first approach, that was evident in the opinions of Maududi and he was the chief spokesperson, placed his interpretation of Islam, Qur'an and Sunnah based on the second approach. From view of Ghamidi, politically Islamic society establishment is precedence over the Islamic government. This society is possible through an Islamic Revolution and Revolution will pave the way for an Islamic state. The Islamic state is combination of three groups: Muslims, Mu`ahids and Zimmis. Such a state based on pluralism in religion and politics.

Abstract
Aims: In this study, the replacement effect of dietary fish meal with AquPro (Processed soybean meal) was assessed on growth performance, body composition and total protease activity of rainbow trout (Oncorhynchus mykiss) over a period of 6 weeks.
Materials and Methods: In this experimental study, at the beginning of the trial, 5 experimental diets were formulated with fish meal as control (A) and diets with 25% (B), 50% (C), 75% (D) and 100% (E) AquPro, respectively. At the end of the feeding trial, growth performance, body composition and total protease activity from pyloric caeca and intestine were measured.
Findings: The results indicated that the WG, SGR and ADG in experimental diet C were the highest and showed a significant difference with other treatments (p<0.05). However, the status index in experimental diet C was lower than other treatments, but did not show significant differences (p>0.05). The moisture content, fat, and body ash were respectively, significantly higher in experimental diets A, B and E than those of other treatments (p<0.05), But the highest amount of protein was observed in the experimental diet of C, which did not show any significant difference with other treatments (p>0.05). The highest total protease activity from pyloric caeca and the intestine was observed in the fish fed with diet C which showed a significant difference with other diets (p<0.05).
Conclusion: Based on the results of growth performance, body composition, and total protease activity was revealed that the diet containing 50% AquPro could be appropriate for rainbow trout growth.

Abstract
Previous investigations related to tree-fungus beetle, Xylographus bostrichoides (Dufour) (Coleoptera: Tenebrionoidea: Ciidae) have not studied beetle's morphology in detail. This beetle is associated with tree fungi and collected from Fomes sp (Polyporales: Fomitopsidaceae). Pregenital ring, and the almond-shaped plates of abdominal terminalia, are useful characters for the species identification. Also, frontoclypeal area, first abdominal sternite, and abdominal terminalia are the important characters for the female and male separation. The larvae and adult specimens of X. bostrichoides (Dufour, 1843) studied here were found feeding on the dried fruit body (basidiome) of Fomes sp., which had been stored for a long time as a mushroom stored product. The signs and symptoms of the beetle damage (feeding) on the mushroom are also described.
