From a histo MoreObjective of the research: Family, as the most basic and important member of the social institutions, provides the indispensible needs of human beings and plays an undeniable role in the upbringing of the generations and the transfer of cultures and values. From a historical standpoint, family-orientation in Iran is one of the indexes of the values of cultural systems. The unavoidable changes in the new period can affect the family's structure and functions. The aim of this research is to combine and merge the results of accomplished researches in the realm of family so as to identify of strengthening and erosive factors in Iranian families. Method: This research is practical in objective and is of meta-analysis nature in terms of the documentary method of studying. The statistical sample is 64 research-based works concerning the factors affecting the family institution which have been gathered up to the point the data is complete. Findings and Results: The results of the research showed that most works are scientifically endorsed in terms of having common theories. Due to the reliance on particular variables, there is a kind of reductionism in the study. There is a need for a more solid and comprehensive theory-making in the analysis of the family institution in the ecosystem of the Iranian-Islamic culture. In the final analysis, a specific pattern of the factors affecting the family was derived, which is the result of the factors being analyzed by the researchers, in 11 subject topics which are as follows in order of priority: "cultural factors( includes Faith, beliefs and moral Values), family cooperation, mental and physical well-being, individual growth, the manner of managing the family life, the economic affairs and financial well-being, the cultural, social and political climate of the country, the age difference between the couples, the duration of matrimonial relationship, public services and transport and the consideration of society's sanitations".

The present study is mixed due to the use of qualitative and quantitative methods. The theoretical population of research is senior banking managers and experts in the field of resilience and economic resilience. The research sampling method was judgmental and non-probabilistic and samples were selected based on expertise in the field of research. Two tools of interview and questionnaire (expertise and SMART) were used to collect data. Binominal statistical test and SMART were used to analyze the research data. In the first stage, the effective factors on banking strengthening were extracted through literature systematic review and interviews with experts. Due to the large number of factors, low importance factors were eliminated by using Binominal test. The remaining 28 factors were classified into 6 main categories: risk acceptance, organizational structure, learning, high reliability, degree of system softness, and support mechanisms. Then, using the SMART, sub-factors were ranked in each category. According to the score of factors, the sub-criterion of the existence of stress analysis mechanisms in the risk acceptance factor has the highest priority. Sub-factors of system interchangeability, rational selection, creative destruction, holism, and the existence of support systems were given the highest priority in the remaining categories.

This identity played a significant role in the spread of Shiism and Shia religious rituals. The Safavid kings maintained the appearance of religion and performed religious ceremonies and rituals in order to legitimize their rule. Likewise, the people followed these rituals. During this period, the Shiites had the opportunity to hold Shia religious rituals freely and away from the opposition. These beliefs and rituals are well reflected in the poems of Saeb, the greatest poet of the Safavid era. Influenced by the Shia rituals and beliefs of his time, Saeb has devoted many verses to the subject of Shia religious rituals in the form of transition and reinforcement. In this research, which is written in a descriptive-analytical method, the reflection of several types of Shia religious rituals in the Safavid era in Saeb's poetry will be studied. Also, the reflection of Shia religious rituals divides into two groups of transitional rituals and reinforcement rituals according to the classification of religious rituals in cultural anthropology. The research findings show that the reflection of these religious rituals in Saeb's poetry is based on Shia teachings and beliefs influenced by Safavid religious policies and the social conditions of the people.

Family is an institution that is formed based on the marriage of a man and a woman and develops with reproduction. This institution is the basis of building human personality and the most important factor in the evolution of society. The present article is descriptive and analytical and the findings indicate that Islam as well as mystical teachings have provided very important guidelines for establishing and consolidating this fateful institution and preventing its collapse. Reflecting on these guidelines clearly shows that these two rich sources are rooted in divine revelation and are in accordance with human nature, and there is no other way to protect the family and prevent its collapse than following the guidelines of this divine religion.

The desired family system in Islam is formed with the focus on men and women and welcomes any correct method that leads to the strengthening of marital relations and practical mysticism and spiritual conduct are among these methods. In practical mysticism, the seeker tries to interpret all his affairs in relation to God and see him present and present in his life. Using practical mysticism, the seeker realizes what he has to do and moves on to reach intuition and the truth of existence. Having these states for the seeker does not mean being away from society. In Islamic mysticism, mystics live in spiritual conduct, at the height of disregard for the world, like other peoples, and use the advantages of social life to strengthen the Seleucid aspect, and their mystical perceptions for their social life. Therefore, the formation of a family and the correct relationship between couples has always been considered in the life of the Prophet (peace and blessings of Allah be upon him) and the Imams (peace and blessings of Allah be upon him), and the author intends to answer the question and what role does practical mysticism play in strengthening couples' relationships?

Therefore, in order to maintain the performance of these structures, it is necessary to retrofitting them. FRP materials are one of the suitable materials for strengthening structures against vibration loads such as earthquakes. However, due to the high cost of FRP and the difficulty of execution in the strengthening of existing structures, it is very important to provide new efficient methods for the use of these materials. For this reason, in the present study, the use of FRP strips for stregthening of beam to column joints was investigated and its effect on joint behavior was studied. For this purpose, ten models were introduced, modeled and analyzed with ABAQUS software. The results showed that the use of horizontal and diagonal strips on the beams increased the joint strength up to 37%. The final displacement of the beam also increased up to 102%. The present study showed that the use of FRP stripes is an effective technique for improving RC joints Manuscript profile -

After numerical analysis of prestressed concrete beams with and without reinforcing fibers, their bearing capacity was investigated. After numerical analysis of prestressed concrete beams with and without reinforcing fibers, their bearing capacity was investigated. It was concluded that in the simple reinforced concrete and prestressed beams, cracks resulting from tensile damage in the middle cross section of the beams with maximum stress are continuously reduced with a gentle slope towards the supports. In simple reinforced concrete and prestressed beams, the highest stresses were created in the tensile reinforcements at the bottom of the beam and in shear reinforcements, the stress get started in the middle section of the beams and exhibited its maximum in the lower part of the beam section. In addition, in simple prestressed concrete beams, the capacity was increased by raising the number of prestressed tendons from 1 to 2 and 3. The capacity of beams with 3 tendons has increased by 79% and 22% compared to the beams with 1 and 2 tendons, respectively. The bearing capacity of prestressed concrete beams with C50 consumption category were increased by 6% and 5% contrasted to the prestressed concrete beams made of C30 and C40 concrete categories, respectively. By comparing the reinforced models using carbon reinforcement sheets in comparison with the glass type, the bearing capacity of beams containing carbon fibers are enhanced by about 12% (on average) compared to different types of glass fibers.

Ext MoreStrengthening reinforced concrete beams using fiber reinforced polymer (FRP) materials compared to other strengthening methods due to its low weight and easy transportation, high resistance with less manpower has been accepted as a common practice in most countries. Externally bonded reinforcement (EBR) and near surface mounting (NSM) reinforcement are common methods for FRP installation. In this research the strengths, weaknesses, opportunities and threats of these two methods are identified as the strengths, weaknesses, opportunities, and threats (SWOT) method from the perspective of construction management and then the structural equations modeling (SEM) method is used to investigate the relationship between each of these variables. Two separate models were used in the EBR and NSM methods that identify the relationship between strengths, weaknesses, opportunities and threats as hidden variables and then questionnaire questions related to each of these variables as explicit variables. Also, confirmatory factor analysis and Cronbach's alpha coefficient were used to assess the validity and reliability of the questionnaire, respectively. The results of this study showed that each of the EBR and NSM methods has different advantages and disadvantages and then management solutions were evaluated using SWOT technique and structural equation modeling.

The corrosion or lack of steel bars in reinforced concrete members and the resulting deterioration of structures prompted research on fiber reinforced polymers (FRP) bars as potential reinforcement for concrete members, for use in new construction. These FRP bars can be used to increase flexural and shear capacity of existing concrete members at NSM (Near Surface Mounted) method. The paper presents the details and results of the experimental and numerical programs. Two large-scale reinforced concrete beams were designed, constructed, and tested under one point concentrated loading system. The specimens had two fixed-end support. They were in same size and reinforcement characteristic. A new type of CFRP bar was proposed in this study, the CFRP bars were manually made in laboratory and were hooked at end for anchoring in concrete. The test results has been used to calibrate the analytical models. Moreover extra analytical work has done. The results indicate that FRP bars can be used effectively in existing structures to increase their flexural capacity and change their crack pattern. Photographs taken at selected stages of loading illustrated the performance of each specimen. The force-displacement was presented and compared to find efficiency of FRP bars at NSM method.

Strengthening the reinforced concrete beams with respect to their type and how they are made is assessed in this study. Although both of the near-surface mounted (NSM) and externally bonded reinforcement (EBR) methods have advantages and disadvantages and it depends on the reinforced member and the project conditions, but in general, the NSM method outperforms the EBR while somehow (EBR) is adopted more. A researcher-designed questionnaire consists of ten restrictive factors regarding NSM implementation. The responding persons consist of skilled experts with at least five years of experience in this field. The execution of risk management in NSM, obstacles on the way of implementation, and the effect of risk management on the functionality of these factors are of concern here. The obtained data is assessed through statistical tests. The factors of more execution time, lack of experts, high volume, low knowledge on the client, uninformed employers, consultants and contractors about the existence of this method, complexities in the calculation, big calculating mass, concrete cover 5-7 cm, FRP rebar needed in NSM, high implementation cost and high FRP implementation cost are considered as the restrictive factors affecting NSM implementation. The initial assumption that the ten factors were restrictive as to NSM implementation led to proving that the factor of lack of information about this method within the client, contractor, and consultant was the most effective as a restriction. This proof was obtained through the statistical tests conducted on the assumptions. Manuscript profile -

In this regard, the yield strength of samples was modelled based on the microstructural parameters extracted from x-ray diffraction (XRD) patterns and micrographs using corresponding mathematical equations. The microstructural features and mechanical properties of samples were analyzed by transmission electron microscopy (TEM) and uniaxial tensile test, respectively. The density of stored dislocations was calculated from XRD patterns by famous Williamson-Hall equation. Microstructural characterizations revealed that ultrafine grains as well as non-shearable precipitates were formed gradually by increasing the number of ARB cycles. The yield strength of ARBed samples was increased by increasing the number of cycles and reached to 278 MPa after third cycle. The grain refinement mechanism was the dominant strengthening mechanism in one cycle ARBed sample, contributing a strength increment estimated to about 95 MPa and its positive role was increased continuously by increasing the number of cycles. Also, the experimentally determined yield strength was in reasonable agreement with theoretically determined yield strength from strengthening mechanisms. Manuscript profile -

Data analysis was done with Claizi's (1978) model. After collecting the data, the key concepts and sentences of the interviews were extracted and the main themes were discovered. According to Razavi's biography, these themes include the 4 main themes of preliminaries and conditions, technical and procedural, dimensions of dialogue and consequences. Manuscript profile -

In this research, the tensile properties of carbon nanofibers have been used to create carbon-epoxy nanocomposite and improve the mechanical properties of epoxy nanocomposite, and the effect of the weight percentage of carbon nanofibers on the mechanical properties of epoxy nanocomposite has been investigated. Epoxy with weight percentages of 1.0, 5.0 and 1.5 carbon nanofibers were produced and their mechanical properties were investigated. The results showed that the use of even a small percentage of carbon nanofibers can lead to the improvement of mechanical properties. Manuscript profile
