Storage and dispose of CO2 in aquifers is a promising techniques to mitigate global warming and reduce greenhouse gases (GHG). Measurement of CO2 dissolution rate in saline aquifers is dependent on the finding an appropriate model for gas diffusion. Indirect methods, especially pressure decay, are currently being used to measure molecular diffusivity. The most important point in this method is the useage of appropriate model and analyze the experimental results. In this paper, non-Fick modeling method is used to analyze the experimental data of pressure decay method for CO2 emission in saline aquifers and the results are compared with Fick model with two different types of boundary conditions. For this purpose, by the inverse solution and minimizing the error function between the pressure-time values of the modeling and the experimental using optimization are estimated diffusion coefficient, mass transfer coefficient and delay time. The results show that with respect to the non-equilibrium boundary condition the diffusion coefficient was more than doubled compared to the equilibrium boundary condition and the non-equilibrium boundary condition is more consistent with the experimental results. On the other hand, the nonfickian model delays the equilibrium arrival with a delay time regulator term and is more consistent with the experimental results, especially in the early moments.

The statistical sample was 220 people who were selected as available. Employee Empowerment questioner of Matthews, Diaz and Cole (2002) and Organizational Learning by Gomez, Lorente and Cabrera (2005) and Information and Communication Technology by Abdavi and Fathi (2016) were used to collect data. The reliability of the questionnaires was confirmed using Cronbach's alpha coefficient. Regression and correlation were used to test the research hypotheses. Then, to test the research model, structural equation modeling method was used using LISREL structural equation software. The results showed that information and communication technology and learning organization affect employee empowerment. also the learning organization influences the empowerment of employees through the mediating role of information and communication technology in the country's skating boards.

Organ transplant recipients are vulnerable to fungal infections. The aim of this study was to determine the prevalence of fungal colonization and infections among patients who underwent various transplantations and molecularly characterize the etiological agents.

This study was conducted on candidates for transplantation in Imam Khomeini Hospital, Tehran, Iran, from April 2017 to April 2018. All patients were monitored for fungal colonization or infections before and after transplantation. Isolated fungi were identified using molecular methods.

A total of 125 patients, including 86 males and 39 females, with the mean age of 52.2 years participated in the study (age range: 15-75 years). Out of 125 patients, 84 (67.2%) cases had fungal colonization that appeared pre- and post-transplantation in 21 and 63 cases, respectively (alone or concurrent with another infection in 55 and 29 cases, respectively). In addition, a total of 39 episodes of fungal infections were diagnosed in 36 (28.8%) recipients (alone or concurrent with colonization in 7 and 29 cases, respectively). Out of the 39 fungal infections, 9 cases appeared pre-transplantation, while the other 30 cases occurred post-transplantation. However, no fungal colonization or infection was observed in 34 (27.2%) patients. Oral candidiasis (n=20) was the most common type of infection, followed by funguria (n=7), onychomycosis (n=5), candidemia (n=3), rhinocerebral mucormycosis (n=1), cutaneous mucormycosis (n=1), cutaneous aspergillosis (n=1), and peritonitis (n=1). Six yeast species were recovered from colonization cases with the dominance of Candida albicans both before and after transplantation. The observed fungal infections were caused by 11 distinct species, including the members of Candida (i.e., C. albicans, C. glabrata, C. parapsilosis, C. tropicalis, and C. krusei), Aspergillus (i.e., A. oryzae and A. candidus), Rhizopus (i.e., R. oryzae and R. microsporus), Trichosporon asahii, and Trichophyton interdigitale. The results also indicated that the development of a fungal infection post-transplantation was associated with fungal colonization (r=0.0184; P=0.043).

Based on the results, fungal colonization was a common finding in transplant recipients at Imam Khomeini Hospital. However, the incidence of fungal infections was comparable with those of other centers. As the oral cavity was the most common site of colonization and infection, it might be beneficial to take further care about the oral health of patients using effective mouthwash.

Jabal Amel is a region in the Southern Lebanon, near the Mediterranean Sea, extending as far as Palestine. It includes the cities of Sour, Sidon, Bint Jbeil, Nabatieh. The inhabitants of Jabal Amel are Shiites and share many religious beliefs with Iranians. Therefore, there are many similarities in Ashoura poetry of Jabal Amel and Iran. In Iran, the fall of the monarchy and the victory of the Islamic republic opened a new chapter in contemporary Ashura poetry and created a new trend in the composing of religious, Ashoura poetry, the diversity and expansion of which was unprecedented. On the other hand, the presence of colonizers, the frequent invansions of the Zionist regime, and the resistence of Lebanese people against them in Jabal Amel have led poets to work on Ashura poetry more than before. This study tries to study and analyze the main common Ashura themes in contemporary poetry of the two regions.

"Fitrat” (innate nature) is one of the most fundamental theories in Islamic anthropology. Introducing innate nature as a nonacquired, universal and constant issue based on monotheism, Islam regards it as one of the necessary foundations of anthropology that could be the basis for other theories. The present paper investigates the possibility of the stability or variability of nature in the form of three hypotheses: the variability of innate nature, the stability of innate nature and its actuality, and the stability of innate nature and its potentiality. Each of these hypotheses will have different foundations, principles, goals and methods, and will consequently assign a different responsibility to the educational system. Although nature is perceived as an intrinsic quality in human being, its connection and influence from the environment cannot be denied. The manifestation and development of innate nature requires a favorable environment and an unfavorable environment may lead to its extinguishment.

The purpose of this research is to comparecreativity, positive affection and psychological well-being in adolescents and the elderly. It is a casual-comparative conducted on adolescents (n=100) and the elderly (n=100) which constituted the participants. For the purpose of sampling in adolescents, the multistage cluster sampling was used and for sampling in the elderly, the available sampling method was utilized. The participants filled in positive affection scale by Watson, creativity scale and psychological well-being by Ryff. The findings were analyzed by multivariate variance analysis and independent t-test. The results indicated a significant difference between adolescents and the elderly in terms of creativity, positive affection and psychological wellbeing (p<0.005). That is, adolescents had higher mean creativity and lower positive affection and psychological wellbeing compared to the elderly. Also, the result did not show a significant difference between mean creativity and psychological wellbeing of male and female adolescents (p<0.005), though there was a significant difference in terms of positive affection with female participants scoring higher in this regard (p<0.001). Moreover, the results did not reveal any significant difference between positive affection and psychological wellbeing of the male and female elderly. According to the results, it can be concluded that adolescents had higher mean creativity and yet lower positive affection and psychological wellbeing compared to the elderly. Also, it appeared that gender did not affect the variables under study, though positive affection in female adolescents was higher than their male counterparts Thus, the generation gap in research variables is more obvious than gender differences.

The present study was aimed to compare the early maladaptive schemas and lifestyle in the patients with depression and multiple sclerosis (MS) and normal people. This study was causal-comparative in design. The study sample consisted of 20 depressed and 20 MS patients who were selected through convenience sampling from among the patients referring to psychiatrists and psychologists in Khorramabad. In addition, 20 normal people were selected by matching method. Data were collected by Young Schema Questionnaire (YSQSF), Beck Depression Inventory (BDI), Expanded Disability Status Scale (EDSS) and the original Adlerian Scale for Interpersonal Success (Adult version). The obtained data was analyzed by MANOVA and follow-up Scheffé tests. Based on the results of MANOVA, there was a significant difference between early maladaptive schemas and lifestyle in depressed and MS patients and normal people (P ≤ 0.001). The results also showed that the mean scores of MS and depressed patients were significantly higher than that of normal people in the all components of lifestyle except belonging, social interest, coping, responsibility, striving for perfection and amenity. The results of this study showed that the rate of early maladaptive schemas and unhealthy lifestyle was high in the patients with depression and multiple sclerosis, which could endanger their health. Therefore, it is essential to provide these people with appropriate training to cope with or adapt to these symptoms.
