Epoxy and dicyclopentadien (DCPD) are two common healing agents, which are introduced into epoxy matrix through encapsulation in order to prepare self-healing composites. In a comparative study, the compatibility of healing agents and epoxy matrix is investigated through experimental tests and DFT calculations. The interaction energy is considered to be the determinative parameter in DFT calculation. The values of total interaction energy are-0. 14eV for DCPD and +0. 169eV for epoxy absorbing on epoxy matrix. According to the obtained results from DFT, an attraction between DCPD and epoxy matrix is observed. DOS and charge analysis of these systems are fulfilled and demonstrated the charge transfer of 0. 07 e from epoxy to DCPD. The obtained data reveal the most charge transfer is occurred in DCPD-epoxy, which affects the mechanical properties of healed composites. To examine the mechanical properties, tensile strength parameters are measured experimentally and demonstrated the improved ultimate strength of 783. 49 MPa in DCPD/epoxy system rather than the ultimate strength of 571. 87 MPa in epoxy/epoxy system. Also elongation at break in DCPD-epoxy system is improved to 3. 44% compared to 1. 84% in epoxy/ epoxy blend. These findings highlight the role of interaction energy in mechanical properties of polymeric interface, and prompt further experiments and simulations to confirm this effect.

Water leakage from concrete tunnel structures is one of the phenomena which can affect their serviceability with certain problems. In this paper, the limit states of water leakage from cracked and uncracked concrete elements have been introduced whilst uncertainty of governing parameters is modelled as random variables. Using Monte Carlo simulation, failure probability and corresponding reliability index of tunnel sections with cracked concrete have been calculated in three modes, namely constant crack width, self-healing and expanding. The results of this analysis showed that concrete selfhealing does not have signifcant role in reduction of leakage probability. On the other hand, since crack width spreads during the service life of structure, an appropriate crack width increase model with time is necessary in order to determine the remaining life of tunnels. Moreover, for uncracked sections and sections that must be necessarily sealed, probability of leakage initiation has been computed during the service life of tunnel. For such structures, this reliability analysis can be utilized to determine the remaining life corresponding to the acceptable failure risk or in designing the minimum required thickness of element and determining the properties of mix design and permeability of concrete.

The rapid growth of grid-connected embedded distributed generations (DGs) is changing the operational characteristics of distribution networks (DNs). In order to implement DNs with DGs, some challenges should be faced, especially concerning protection issues, that may make conventional protection schemes ineffective. MAS techniques can enable the power grid to becomes smarter, reliable, selfhealing, and robust. Its decentralized nature and operational robustness make the MAS application a leading technology. Despite the fast, reliable and multi-purpose operation of MAS-based protection schemes, the inherent delay or failure of communication system must not affect the vital role of fault clearing, i. e., the ever-increasing DGs in DNs as well as network size increase has resulted in a heavy communication burden yielding to delay or even failure in communication. In this paper, an Intelligent protection algorithm is presented that protect the grid, when the connection between agents is lost, by using point-to-point communication between relay agents in the first layer of the MAS. Reduction of the agents used and no need to connect to the higher layers of the MAS are the benefits of this method. For simulation, 16 bus Test DN is used, that The results confirm the applicability of the proposed model for grid protection coordination.

Introduction: Type II diabetes is one of the chronic diseases, and diabetes distress is one of the psychological factors affecting its management. Therefore, this study was performed to compare the effectiveness of self-healing with mindfulness-integrated cognitive behavior therapy on diabetes distress and control of glycemic in type II diabetic patients Methods: This semi-experimental research was conducted on 60 people with type II diabetes who were selected purposefully. People were randomly divided into two intervention groups and one control group. The intervention groups received twelve 90-minute sessions (one session per week) of mindfulness-integrated cognitive behavior therapy and selfhealing. The research tools were Polonsky et al. 's Diabetes Distress Scale (2005), which has content validity and reliability with a Cronbach's alpha of 0. 87, and laboratory equipment to measure hemoglobin glycoside. The data were analyzed using variance analysis with repeated measurements and post hoc tests in SPSS-24 software. Results: Between the two methods of intervention, only self-healing could effectively reduce glycosidic hemoglobin (P≤, 0. 01). Moreover, both methods of intervention reduced diabetes distress,however, the effect of self-healing remained stable over time (P≤, 0. 01). Conclusion: The results indicated that self-healing was able to reduce hemoglobin glycoside in addition to diabetes distress and its effect remained constant over time. It is suggested to investigate the effect of self-healing in other areas related to diabetes.

Background: Leishmaniasis is not as severe as other diseases, often lesions are selfhealing. For various reason as long lasting duration of lesions and treatment, disfiguring scar reminding, secondary infection in lesions, have comfortable treatment method and accessible with less cost, it is necessary various method of treatment with less side effect. The results of previous studies showed that Indoleanalogues, Terpens, Iridoids, Quinones and Alkaloid hemisynthetic derivatives have promising antileishmanial potential. These derivatives were found in Thyme, Henna Yarrow and Garlic.Objective: Access to formulation drug without harmful chemical material and without side effect.Methods: After Inoculation of parasite in base tail of mice, during of three weeks caused lesions in inoculation place, then animal divided to 9 groups. In this study we used 4 alchoholic extract solution 2 times a day. we checked lesions weekly for six week and meseaured size of lesion in the base of tail with kulis – vernieh. Data of study analyzed with Anova, Paired t test and schefeh.Results: We observed significant difference between mean of lesion in before and after treatment in control, Yarrow (Bomadaran) and Thyme (Avishan) groups (p<0.05).Paired t test showed that there were not significant difference between mean of lesion in after treatment between groups of treatment and glucantime groups (p>0.05).Conclusion: Alchoholic extract to Avishan and Boomadaran have good effect on lesions treatment, we suggest that the study could be repeated with Thyme (Avishan) and Yarrow (Bomadaran) extract in gel or cream base in first stage of lesions appearance.

Aim and Background: Binge eating disorder as a psychological disorder commonly leads to confusion and problems for people. A problem People with binge eating disorder is low capacity of distress tolerance, and this increases the tendency of an individual to Binge eating. This study aimed to compare the effectiveness of cognitive-behavioral therapy and self-healing therapy on Distress tolerance in women with bulimia nervosa. Methods and Materials: This study was quasi-experimental (pre-test post-test with the control group). The statistical population of the present study included all women with bulimia nervosa who were referred to specialists and medical centers in Isfahan in 1398. 45 women were selected by purposive sampling and randomly placed in experimental and control groups. Data collection tools were Distress tolerance Simon and Gaher's (2005) questionnaires. Each of the experimental groups underwent 12 sessions of Michelle's cognitivebehavioral group therapy, and Marvi and Latifi's self-healing therapy, but the control group did not receive an educational certificate. Research data were analyzed using MANCOVA and chi-square test. Findings: Based on the chi-square test, no significant difference was observed in terms of age, education, and disease duration between the three groups (P <0. 05). The results showed that the cognitive-behavioral and selfhealing experimental groups were significantly different from the control group in the Distress tolerance variable (P <0. 05). Also, self-healing therapy has increased the Tolerance and absorption dimensions and Distress tolerance more than cognitive-behavioral therapy (P < 0. 05). Conclusions: According to this study, cognitive-behavioral therapy and self-healing can be used to increase the Distress tolerance of women with bulimia nervosa. However, self-healing treatment seems to be more than effective cognitive-behavioral therapy in this case.

Introduction: Considering the psychological effects of cancer such as stress, death anxiety and depression, the use of psychological treatment is very important in reducing the psychological problems of breast cancer. The purpose of this study was to determine the effective training of selfhealing on stress, death anxiety, and depression, in breast cancer patients. Methods: The present quasi-experimental study design with pre-test, post-test, and follow-up design with experimental and control groups. The statistical population of the study included all females with breast cancer in the year 1396-98 referring to seyedshohada hospital in Isfahan city, among 28 selected by the available sampling and were randomly assigned to experimental and control groups. (14 people in each group). For the experimental group, the self-healing program was performed in 12 sessions per week for 90 minutes per session. Data was collected through cohen's Perceived Stress questionnaire (1983), the temple Death Anxiety Scale (1970), and the beck depression Inventory-2(1988) before, after, and two months after the intervention and analyzed by variance analysis test with repeated measures and Bonferroni post hoc. Results: After performing the self-healing program, the mean stress death anxiety and depression in the experimental group decreased from (31/71, 12/71, 29/79) to (22/43, 5/0, 17/0), with indicated a significant reduction in stress, death anxiety and depression(p<0/01) while the control group had no significant difference before (30/71, 12/29, 27/86) and after (29/21, 10/71, 31/7) the intervention(p>0/01). There was a significant difference between the control group and the experimental group in all three variables in the post-test and follow-up stages (p<0/01). Conclusions: The finding of this study showed that the stress, death anxiety, and depression decreased, meaning that the self-healing training program was effective for the stress, death anxiety, and depression of breast cancer. Therefore, this method can be used to reduce the psychological programs in breast cancer and other chronic diseases.

Objectives: Aging is one of the important stages of human development. Death anxiety and sleep quality are among the most common mental health issues in the elderly which can be improved by proper intervention. This study aims to assess the effect of self-healing training on sleep quality and death anxiety of older women living in nursing homes. Methods & Materials: This is a quasi-experimental study with a pretest/posttest/follow-up phase. The study population consists of all older women aged 60-70 years living in a nursing home in Isfahan, Iran in 2020. Of these, 40 were selected using a convenience sampling method and based on the inclusion and exclusion criteria, and were randomly assigned into two groups of intervention (n=20) and control (n=20). They were assessed by the Collett-Lester Fear of Death Scale and Pittsburgh Sleep Quality Index before, immediately after, and 45 days after the intervention. The intervention group received a 12-session selfhealing intervention while the control group was placed in a waiting list without receiving any intervention. The results were analyzed by multivariate analysis of covariance in SPSS software, version 24. Results: The self-healing training significantly improved the components of death anxiety (fear of own death, fear of the process of own dying, fear of the death of others, and fear of the process of others dying) and some of sleep quality components (subjective sleep quality, sleep latency, sleep disturbances, and use of sleeping medication) (P<0. 05). These effects significantly remained constant in the follow-up phase in the components of fear of own death, subjective sleep quality, sleep latency, sleep disturbances and use of sleeping medication (P<0. 05). No significant difference was found in other variables between the post-test and follow-up phases (P> 0. 05). Conclusion: The self-healing training can reduce perceived death anxiety and improve sleep quality of older women living in nursing homes. It can be used as an effective educational method for improving the lifestyle and mental health of older women living in nursing homes.

Leishmaniasis is a zoonotic disease caused by Leishmania parasites, ranging from selfhealing cutaneous lesion to severe and non-healing disseminated cutaneous or visceral leishmaniasis (VL). Cutaneous leishmaniasis (CL) is a chronic infectious and granulomatous disease caused by Leishmania parasites. NO is an inorganic free radical and versatile biological messenger that its biological roles especially as a cytotoxic anti-pathogenic agent released during an inflammatory response and involved in the microbicidal activity of macrophages against L.major as intracellular pathogens. CRP has been found in association with acute infections and a variety of inflammatory disorders. Aspirin can inhibit inflammatory reactions and platelet aggregation, but little is known about the effects of the ASA in leishmaniasis treatment. The purpose of this study was to evaluate of antileishmanial effect of ASA drug in susceptible Balb/c mice infected with L. major through its anti oxidant role with induction of immunity mediators such as NO and CRP in host, inhibition of visceralization of parasite and its effect on healing of leishmania lesion and proliferation of parasite in macrophages in compare with control groups. In order to carry out this investigation, mice were assigned into 4 groups as 2 groups of control and 2 groups of infected Balb/c. Experimental leishmaniasis was initiated by (s. c) injection of the 2×106 L. major promastigotes into the basal tail of infected groups. The appropriate of concentration of ASA was prepared in ethanol (60%) and after appearance of lesion it was inoculated to test groups as oral with gavage. The development of lesions was determined weekly by measuring the two diameters. After 13 weeks, all mice were killed humanly and target tissues including lymph node, spleen and liver from each mouse were removed, weighted and their impression smears were also prepared. Griess microassay method applied for measurement of NO in plasma and target organs. CRP was detected by a rapid latex agglutination test kit. In this study, ASA has some anti- leishmanial effect through changing of NO and CRP as immunity and inflammatory factors in Balb/c mice infected withL.major. It seems application of ASA could decrease parasite visceralization in target organs as well as declining its proliferation inside macrophages, however it has no effects on lesion size, survival rate and hepato/splenomegaly. ASA presented its ability to alter NO concentration in plasma during L.eishmania infection in mice, but it has no effects on liver and spleen NO levels. Although these alterations could affect the proliferation of amastigotes inside infected macrophages, however more studies are required to clarify this concept.
