Using stone column as a suitable liquefaction remediation in Persian Gulf coast.
This research investigates behavior of gravel drain piles under high-level earthquake loading beneath
the structures foundation. To achieve this purpose one of the waste water septic tank project in north
of Persian Gulf in Hormoz Island was selected as a
case study to find suitability of gravel drain pile
system to reduce excess pore water pressure. According to high susceptibility of local soil layers
liquefaction and its short distance of waste water tank to the sea, the mentioned project becomes one
of the most important issues regarding geo-enviro
nmentally hazards impact after tank structural
collapsing. The drain piles were used to control excess pore water pressures beneath the foundation of
mentioned project. Furthermore, different static and cyclic triaxial tests, Standard Penetration Test
(SPT), the hydraulic conductivity and density
tests were conducted to enhance the proper
understanding of the dynamic behavior of soil layer under the foundation. According to the numerical
modeling results, using these drain piles has focal effects on the excess pore water pressure rate and
creates a liquefaction zone during
the time of earthquake loading
Predictors of Life Skills Level of Students in Zahedan University of Medical Sciences in Southeast of Iran
Background and aims: Life skills involve a big class of socio-psychological and interpersonal skills which help a person to take conscious decisions, communicate effectively and improve self-management skills. Preparing a plan for all the above mentioned programs, need awareness about life skills level of different groups such as students in universities. Present study was aimed to reveal the predictors of life skills level of Students in Zahedan University of Medical Sciences in southeast of Iran. Methods: This cross-sectional study carried out on 380 medical students of Zahedan in 2015. The subjects were selected using stratified random sampling method. The data were collected using reliable Life Skill Dimensions Score questionnaire. The data were analyzed in Stata.12 software using ANOVA, Independent t-test and multiple linear regression with Hosmer-Lemshow method. Results: The mean of total score regarding life skills score was 280.8±45.8. The linear regression analysis indicated that gender (β=11.15, 95 CI: 5.03-17.27), socioeconomic status (β=6.78, 95 CI: 1.76-11.8) and average grades (β=15.3, 95 CI: 9.11-21.49) were associated with life skills score. However, the life skills score was not associated with the age, semester, residential area, smoking, marital status and school of education (P>0.05). Conclusion: The level of life skills scores of medical students in southeast of Iran is low in all dimensions especially in communication skills. Thus, promoting life skills in university students is too important. However, the life skills training programs should be implemented with respect to socioeconomic status, gender and average grade and male students with low socioeconomic status and average have priority

A Comparative Study of the "Tasrif" Verses in the Holy Quran in Al-Mizan and Majma Al-Bayan Commentaries
The Holy Qur'an, the last divine book, has conveyed meaning in various ways. One of the Qur'anic modes of conveying meaning is the "Tasrif" method. In fact, "Tasrif" is the expression and transmission of a meaning in different ways. It is meant that Allah Almighty expresses a meaning in different ways. Understanding the method of these expressions has a great impact on a better and clearer understanding of the Holy Quran. The present study is a comparative-descriptive-analytical study that examines the verses of "Tasrif" in the Holy Quran from the perspective of two great commentary ie: Al-Mizan and Majma Al-Bayan. Ten verses of the Holy Qur'an refer to the "Tasrif" method. Including: (Al-An'am/ 46; Al-An'am/ 65; Al-An'am/ 105; Al-A'raf/ 58; Al-Isra/ 41; Al-Isra/ 89; Al-Kahf/ 54; Taha/ 113; Al-Furqan/ 50; Al-Ahqaf/ 27). By relying on these verses you can see that "tasrif" is of two kinds; in the nature (divine creature) and in the divine book. "Tasrif" in divine book is of two kindes: the etymological "tasrif" and the semantic "tasrif". These two scholars have suggested benefits for the "tasrif" style. Including: Learn from the meaning of the verses of the Qur'an, No excuse for people, To avoid false thoughts, To think, To understand the truth, To avoid sin, Thanks to divine blessings, And most importantly they worship God And finally return from disbelief
Viewpoints of Experts of Agricultural Jihad Centers toward the Agricultural Extension: New Approach in Fars Province
Despite the numerous efforts have been done to develop and modernize the agricultural sector of Iran, this important sector has faced many serious challenges. The main role of agricultural extension in developing countries is to transfer new technologies created by research organizations of the public sector through proper methods such as exhibition, farm visits, meeting with farmers, using media, etc. Agricultural extension system is one of the most important means of diffusing agricultural advanced findings and also providing educational and advisory services which play a vital role in the development process, especially rural development. Agricultural extension in Iran doesn’t have a favorable situation and hasn’t been able to grow itself in terms of the approaches and extension methods, the formulation of aims and tasks, and organizing structure and organization. Therefore, it is essential that Iran’s agricultural extension system, while addressing the challenges and failures, prepares itself for more effective management of future changes. This study was carried out in Fars province using survey research method. The stratified random sampling was used in the research. The statistical population of the research was 130 experts of the agricultural Jihad center of Fars. The findings showed that there is a difference between the performance of different activities in the pilot and non-pilot centers from the experts’ point of view. The findings showed that attitude variables were the most effective in predicting the regression model. At last, some recommendations were presented due to the research results in order to improve the performance of service centers’ activities

A comparative study on dust exposure, respiratory symptoms and lung function among farmers and non-farmers
Considering the importance and essence of farmers’ health, this study has been conducted with the aim of evaluating the amount of the dust confronting farmers and the farmers’ respiratory symptoms and function during the course of wheat collection in 2014 in Zabul villages (Sistan & Balouchestan province, Iran).
For this cross sectional study, the dust of the respiratory scope of two groups (farmers and non-farmers) was sampled by PVC filter for 90 minutes with the flow rate of 1.5 lit/min on the basis of NIOSH 0500 method during daily 8 work hours of 5 successive days of manual wheat reaping. Data regarding respiratory symptoms (n=50 rural men over the age of 40) was gathered through interviews and questionnaires, and pulmonary function was measured by Spiro lobe (made in MIR of the US); besides, data analysis was done by SPSS 18, T-Test, Chi-Square, and Logistic regression.
The mean dust intensity confronting the farmers was 36.7 mg/m3, and the rate of some breathing complaints namely coughing (P≤0.001), sputum (P≤0.009) and shortness of breath (P≤0.026) became meaningful in the two groups. The average amounts of spirometer parameters of the farmers were less than that of the non-farmers, and the statistical difference of all the parameters except for FEV1/FVC (P=0.06) was meaningful (P≤0.05). The results of the present study indicated that confronting with dust could cause respiratory complaints and decrease spirometer parameters in the farmers

The role of adverse childhood experiences and attachment style in predicting pain perception in women with breast cancer; the mediating role of perceived social support
Introduction: Breast cancer is the most common malignancy among diseases which is the leading cause of death in women with more than two million deaths per year. Pain in cancer patients has a complex relationship with adverse childhood experiences, attachment and social support, the multiple relationships of which has not been studied to date. The present study was conducted aimed to investigate the multiple dimensions of this relationship.
Methods: In a cross-sectional study in the form of a structural equation modeling, during the period from July to September 2021, 360 participants diagnosed with breast cancer who referred to three chemotherapy centers in Tehran were selected using purposeful sampling method and entered into the study process after obtaining informed consent and fulfilling the assumed criteria. Four indicators of adverse childhood experiences, attachment style, pain, and perceived social support were completed by participants over a period of time. Data were analyzed using SPSS and Amos software version 25.
Results: Data analysis showed that adverse childhood experiences mediated by perceived social support was associated with the perception of pain in women with breast cancer (P<0.05). But the relationship between avoidant (β = 0.015), safe (β = -0.023) and ambivalent (β = 0.026) attachment styles with pain perception was not significant and attachment styles through perceived social support could not have a significant effect on pain perception (P >0.05).
Conclusion: some parts of the findings of this study, in line with the research background, indicate the relationship between adverse childhood experiences and pain perception and highlight the role of perceived social support. However, the relationship between attachment styles and pain perception is a complex one that requires further study
