Abstract: 

A B S T R A C TThe morphology of each region is related to its landforms, the morphology of flat areas is related to inselbergs. The presence of inselbergs in desert and dry areas gives a special appearance to the morphology of these areas. The study of these landforms and the effective factors in their formation is considered a necessity in terms of regional development. According to the studies, various factors play a role in the formation of inselbergs, and the role of lithology seems to be more prominent. In this research, which was conducted with the method of field and library studies, we identified 18 inselbergs in Safi Abad plain and by studying them, we came to the conclusion that the inselbergs of this plain are mainly formed in sedimentary rocks such as limestone, conglomerate and sandstone. Among the geological formations, the largest and most diverse inselbergs in the Safiabad plain are formed in the mass conglomerate formation with good hardening because this formation is the most widespread in this plain. But the most typical inselbergs of this plain are formed in thick layered limestone. Because this formation is more resistant to erosion. Lar Formations including Limestone and Thick Limestone’s to Mass Dolomite and Delichai Formations have also played an important role in the formation of inselbergs in this plain. Although the extent of these formations is not significant, but due to their significant resistance to erosion and being far from these processes, they have caused the formation of evolved inselbergs in this plainExtended AbstractIntroductionInselbergs are ridges with a height of less than 500 meters formed with a steep slope in the plains. Their resistance to erosion has caused them to be considered capable players in the morphology of arid and semi-arid regions. Due to their uniqueness in desert areas, these areas are of interest to tourists, and the economic situation of these areas can be improved by attracting tourists. The prominence of inselbergs in desert areas has caused researchers to pay attention to their studies, the most important of which are the studies of Pye in Kenya (1984), Nenonen in Finland (2018), Luiza in Brazil (2021), Laetitia in Africa (2019), and Mashaal in Egypt (2020). Although the conditions for inselberg formation are available in some areas of Iran, and these landforms have given a particular face to the morphology of this country, no significant study has been done on them so far. This research attempts to investigate the role of lithology in inselberg formation in Safi Abad Plain by using library and field studies. MethodologySafi Abad plain in the northeast of Iran and North Khorasan province and in terms of geographical coordinates between 36-˚ 48-05 to 36-22-55˚ North and 37-57˚ East to 36-˚ 37-08 It is located at 57-58-11 east. Field and library studies were used to study the inselbergs of this plain. The entire region was surveyed in 2 years in the field studies, and 18 inselbergs were identified. Then, the location and extent of their expansion were determined. In the morphometry that was done as a survey, the minimum height, length-to-width ratio of inselbergs, and their distance from each other were measured with GPS. The study of the concepts, definitions, and effective processes in inselberg formation was done with the library method. The maps of this research were drawn with Adobe Illustrator software. Results and discussionInselbergs are diverse in terms of morphology; in the studied area, 18 inselbergs were identified, most of which are mixed. Most of them are rocky and have less vegetation. Regarding lithology, inselbergs are particular forms of igneous and metamorphic rocks, but some are also formed in other rocks. Although lithology plays an essential role in inselberg morphology, it cannot be claimed that inselbergs formed in the same formation have the same shape. Although the dominant lithology of the Safi Abad plain is formed from sedimentary rocks, due to the different resistance of its formations, the height, shape, and slope of the inselbergs of this plain are different in different parts of the region. The difference in these characteristics has caused the different shapes of the land in this plain. According to the studies of the most resistant formations of Safi Abad plain against erosion, limestone is a thick layer of chert mass formed due to the resistance against the erosion of the complete inselbergs.After this formation, the Lar formation consists of fine-grained uniform dolomitic limestone with thick to massive layering, which is more resistant; that is why many inselbergs in the region have formed in it. The third formation in terms of resistance is the Apsin-Albin unit, which includes orbitolinate limestone and thick limes to a mass of dolomite. Although this unit has a small area, its inselbergs are closer to typical inselbergs. In terms of area, most of the area is composed of mass conglomerates with good hardening. Due to the different effects of this formation from different processes, its inselbergs do not have the same morphology. The inselbergs formed in this formation are in the middle part of the high area, low in the southern part, incomplete in the western part, and incomplete mushrooms in the path of the Gerati River. After this formation, gray shales are the most resistant to erosion. This formation, which belongs to the Jurassic period, has formed a large part of the northeastern inselbergs. The alternation of limestone and marl in the Delichai formations in the middle part of the region provides the basis for the formation of mushroom-shaped inselbergs in the future. ConclusionSafiabad Plain is in the northeast of Iran, and in terms of geomorphological units, it is part of central Iran. Inselbergs form part of the morphology of this plain. In this study, 18 inselbergs were identified in this plain, and their detailed study showed that their primary skeleton was established by tectonic activities in the Devonian to Miocene period with the formation of Posht Bahram mountains. It was formed when the tectonic activities calmed down and in opposition to the lithology and erosion of the inselbergs of this plain. In terms of lithology, the well-hardened conglomerate formation covers nearly 47% of this plain, and due to its large size and different distances from erosion processes, various inselbergs have been formed in it. The southern inselbergs formed in this formation have a regular shape due to wind and blue erosion. In contrast, the middle inselbergs have an incomplete shape due to the distance from higher erosion, and the western inselbergs have an incomplete shape due to the superiority of blue erosion. Another formation that plays a vital role in this field is Lar Mei Formation. Although this is the second formation in terms of size and strength, many inselbergs have formed in it. The Shemshak formation is placed after the Lar formation in terms of resistance. This formation has caused the formation of chain inselbergs in the northeast of the region. The most typical inselbergs of the region are observed in the thick layered limestones of the formation (Maastrichtian). Also, this research found that inselbergs may be formed in all flat areas of the world and even in sedimentary formations. However, the inselbergs formed are far from those formed in tropical regions' igneous and metamorphic formations. FundingThere is no funding support. Authors’ ContributionThe authors contributed equally to the conceptualization and writing of the article.

Abstract: 

Iran, due to its geographical location, has low rainfall and is considered a dry land. As a result, different regions of the country grapple with drought. The presence of water management systems, such as aqueducts and reservoirs, in most parts of the country, along with a variety of methods for conserving water for irrigation, may contribute to this claim. Considering that drought is an inherent phenomenon in Iran's climate, people have invented and used numerous methods to combat it and store water. The aim of this study is to monitor and evaluate drought in Iran. In order to realize this goal, precipitation data from synoptic, rain gauge, and climatology stations were extracted over a 51-year period, from 1970 to 2020. The results obtained from examining drought occurrences in five ten-year periods reveal that, with the exception of the third decade (1991 to 2000), drought has prevailed in the majority of Iran's regions compared to other decades. On the other hand, in the recent decades leading to 2020, the intensity of drought occurrences, especially in the Middle Zagros, has intensified, which has consistently been among the regions with the highest rainfall in Iran after the Caspian region. This situation can cause concern in Iran, a country where its agricultural production hub is established along the Zagros mountain range. Moreover, the fluctuating behavior of Iran's droughts, with return periods of 2 to 5 years, has complicated the management strategies for these types of hazards. These conditions appear to have created numerous issues in many areas of Iran, particularly in the agricultural sector of the western provinces, due to the lack of conformity with these types of occurrences.

Abstract: 

Ants are a major part of the ecosystem as they assist in the decomposition process and improve soil quality. In this study the species richness and biodiversity of these arthropods was assessed in the habitats with varying degrees of human impact in Shiraz, Fars Province, southern Iran. To this end, six habitats including three city parks with the least amount of human destruction (Be’sat, Janat, Babakoohi), two habitats with high amount of manipulation in order to agriculture and urbanization (a field and a destroyed garden) and a natural park without any human manipulation as control, were chosen and sampled bimonthly during 2015 and 2106. A total of 6270 ant workers belonging to 30 species, 12 genera, and three subfamilies were recorded. The most abundant subfamily was Formicinae (16 species) followed by Myrmicinae (12 species), and Dolichoderinae (two species). The biodiversity indices showed a greater diversity in both natural park and urban landscape: Be’sat and Janat parks, with the lowest amount of human effects, respectively as well as Babakoohi and the lowest in the field and destroyed garden. Although a significant difference was observed with the habitats (F= 4.255, P=0.004) and the months (F= 4.327, P=0.002) of sampling, there was not a significant difference between Babakoohi, natural park, Janat and Be’sat parks (P>0.05) nor between field and destroyed garden (P>0.05).

Abstract: 

This research article examines legal discrimination against children born out of wedlock in Iran. Despite laws promoting equality, societal attitudes influenced by beliefs continue to result in discrimination. The study explores the reconciliation of religious beliefs with legal frameworks and the changes made to the Iranian legal system in response to positive human rights developments. The Article seeks to bridge the research gaps by comparing the experiences of Iranian children with those in other countries affected by Islamic law. The study employs library sources and descriptive and historical research methods to examine the legal status of children born outside of marriage, both nationally and internationally, and the discrimination they face. The Article is structured into four distinct sections: an analysis of Islamic Law, a review of the Iranian legal system, an assessment of Iran's compliance with international conventions, and a discourse on the necessity of substantial positive change. The Article ultimately recommends the eradication of discrimination through heightened awareness and the advancement of inclusivity for all children, irrespective of their lineage. In summary, this research Article aims to shed light on legal challenges faced by children born outside of marriage in Iran, with the goal of promoting positive changes in their treatment.

Abstract: 

Improving participation in voluntary activities in Iran is important because increasing productivity among young people, given the country's young population, contributes to community sustainability. Therefore, a better understanding of volunteer motivation in Iranian youth is needed. The Volunteer Functions Inventory (VFI) for assessing volunteer motivations has good psychometric properties and is adapted to several languages, but no validated Iranian translation yet exists. The purpose of this study was to investigate the psychometric Characteristics of voluntary functions inventory in members of Iranian Red Crescent Society. Sample size was 595 members of Youth Organization of Iranian Red Crescent Society from 31 provinces and 175 cities of Iran that were selected by multi-stage cluster sampling method and responded to voluntary functions inventory. Data were collected using a demographic sample and voluntary functions inventory (VFI). Confirmatory factor analysis using principal components method was used for data analysis. The results of the present study showed that the voluntary functions inventory had validity and reliability. Also, the factor structure showed that 29 items and 6 factors well assess people's attitudes to volunteering, and the structure of this inventory was well-fitted and confirmed all goodness of fit models. The present study provides the use of the Iranian translation of the Voluntary Functions Inventory (6 scales and 29 items) to assess volunteer motivation among young Iranian volunteers.

Abstract: This study sought to answer the question of what are the causes of marital infidelity in the Iranian family. To Answer the Research Question, Qualitative Meta-Synthesis (QMS) Method Were Used. Then, 78 Scientific Papers Which Were Considered Marital Infidelity in Iran were identified and were Analyzed. The results showed that the factors of infidelity in Iran can be classified into 9 main categories, including: 1. Social factors, 2. Psychological factors, 3. Cultural factors, 4. Family factors, 5. Personal factors, 6. Relational factors, 7. Economic factors, 8. Media factors, 9. Contextual factors. Each of the main Categories is divided into Different Subcategories. The Social Factors of infidelity were including “Infidelity Opportunities”, “Friend groups” and “Environmental Conditions”. Psychological Factors of Infidelity Were Including “Personality Type”, “Attachment Styles”, and their “Love Schema”. Cultural Factors have Pointed to “Change in Beliefs and values” and “the level of Religious Education” of people. The Family Factors were including “Inappropriate Marriage”, “Family Conflict” and “the Kind of Family Background of people”. The Personal Factors are “Sexual Dissatisfaction”, “Emotional Dissatisfaction”, “the Feeling of Loneliness”, “the Spouse Unavailability”, “Weakness in Controlling Spouse”, “Domestic Violence”, “Revenge of the Spouse” and “the Role of the Third Person in the Relationship”. The Economic factors are including “the Economic Status of the person”, “the Role of Economic Problems”, “the motivation of entering into infidelity under the Pretext of Job promotion”. The media Factors Were Emphasized on “weakening Iranian Values through Social Media Networks and Foreign Satellite Channels” and “Producing of New Needs by Media”. Finally, the Contextual Factors were including the Role of “Age” and “Gender” in the Infidelity. Findings showed that Infidelity Occurred in the group of men and youth in Iran, more than other Social Groups.

Abstract: 

The importance of female heads of households in providing the basic needs of household members on the one hand and the limitations they face in most socio-economic fields have made it necessary to pay attention to the issues of female heads of households in most societies including our country. The purpose of this study is to use the systematic review method to review and evaluate the policy proposals that have been proposed in Iran for women heads of households. A total of 296 articles and 5 reports were identified. In the review and eligibility phase, the total number of selected texts was considered to be 79 texts, of which 62 studies used the quantitative method and 17 studies used the qualitative method. Based on the studies that proposed policy proposals, the characteristics of female heads of the household, the axes of vulnerability, the evaluation of policies and proposals were determined. The findings showed that more policy proposals were made based on the characteristics of low literacy, being unemployed, and being middle-aged. Based on the axes of vulnerability, women heads of households are more vulnerable psychologically and socially than they are materially vulnerable in many cases. The evaluation of policies for women heads of households showed that the most interventions for the empowerment of women heads of households were focused on the economic field and were mainly pursued in the form of financial payments and did not pay enough attention to other aspects of women's empowerment, while the empowerment of women heads of households was successful when It is expected to simultaneously pay attention to their mental health and improve their social and economic status.

Abstract: 

To evaluate the effects of different treatments on seed dormancy breaking of Notobasis, two separate experiments were conducted at Agricultural Sciences and Natural Resources University of Khuzestan, in 2017 with three replications. The first experiment included nine physical, mechanical and chemical treatments (control, surface scarification, intense scarification, one and two weeks of chilling at 4°C, soaking into hot water for two hours without scarification , soaking in 25°C distilled water for two hours with scarification  and acid treatment for six and 12 minutes) based on completely randomized designs (CRD). The Second experiment was hormone priming arranged as a factorial experiment based on completely randomized design with gibberellin concentrations (0, 200, 400, 600, 800 and 1000 ppm) and priming duration (12 and 24 hour) as the treatments. The highest seed germination (40%) obtained from 12 minutes of acid treatment. Results showed that seed germination reached to 100% after priming seeds with GA3 concentrations for 12 hours. However, increase the priming durations to 24 hours, significantly declined seed germination to 47% in 200 and 400 ppm of GA3 concentrations. The Increase of GA3 concentrations in 12 hours led to a linear reduction of T50 from 31 hours in 200 ppm to 19 hours in 1000 ppm). In 24 hours of priming treatment, T50 followed a Gaussian function and the highest T50 (92 hours) was obtained from 600 ppm. It is recommended to immerse the seeds for 12 minutes in sulfuric acid and prime with 400 ppm GA3 acid for 12 hours to break dormancy and increase the vigor index.
