Analytical solutions of the QCD⊗\otimesQED DGLAP evolution equations based on the Mellin transform technique in NLO approximation

In this paper we present a new and efficient analytical solutions for evolving the QED$\otimes$QCD DGLAP evolution equations in mellin space and obtain the parton distribution functions (PDFs) in perturbative QCD including the QED corrections. The validity of our analytical solutions, which have done in the next to leading order QCD and the leading order QED approximations, are checked with the initial parton distributions from newly released CT14QED global analysis code (Phys. Rev.D93,114015(2016)). The evolved parton distributions are in good agreement with CT14QED code and also with those from APFEL (Computer Physics Communications 185, 1647 (2014)) program

A Campbellian Analysis of Departure in Shaffer’s The Gift of the Gorgon

Among the mythologist of the 20th century whose concern was to relate any mythical story to the human psyche and studies of human psychology, Joseph John Campbell (1904-1987) — An American mythologist, professor, writer, speaker, and anthropologist- was greatly influential. Campbell brought to life the myths and legends of cultures throughout the world when he introduces his theory of Monomyth or hero’s journey—the term he borrowed from James Joyce’s Finnegans Wake. Departure, initiation, and return are his monomyth three stages; each of them is divided into some subsections. Among Campbell’s contemporaries, Peter Shaffer (1926) — an English playwright and screenwriter of many award winning plays- is the one moving readily from farce to the portrayal of human suffering in his myth-like plays .This study attempts to highlight the quotations carrying either concepts of monomyth and demonstrate that Peter Shaffer’s play The Gift of the Gorgon is a mythical one, where several elements of departure glamorously glitters

Evaluation of nitrogenous compounds, microbial changes and electrophoresis pattern during fermentation of Mahyaveh, the Iranian traditional fish sauce

Mahyaveh, the Iranian traditional fish sauce is a product with distinct flavor that is produced by fermentation of small and underutilized fish species in the presence of high salt concentration. Fish sauce is mainly used as food flavoring and seasoning in the southern provinces of Iran such as Hormozgan and Fars. In this research, the process of Mahyaveh preparation from the Persian Gulf anchovies was performed in the lab. Fish sauce was prepared by incubating mixtures of anchovies and saturate brine in the pottery containers at 37 C during 54 days of fermentation. The total changes in bacterial count and nitrogenous compounds were investigated in all of six stages of fermentation. The results showed that the total nitrogenous compounds including formaldehyde nitrogen, amino acid and volatile nitrogen increased sharply during the periods of fermentation but trimethylamine contents dramatically reduced in the final stage after increasing moderately in the early stages of fermentation. High Pearson correlation (r=0.8) between total bacterial count and trimethylamine confirmed the existence of relationship between these variables in the process of fish sauce fermentation. The results of SDS-PAGE pattern showed that the number and intensity of protein bands were reduced during fermentation time

Impacts of Antenatal Educational Interventions base on BASNEF Model on Mothers' Breastfeeding Self-Efficacy: A Quasi-Experimental Study

Breast-feeding self-efficacy is defined as a mother's confidence in her ability to breastfeed her child. It is one of the variables affecting breastfeeding duration and consequently developmental indicators in child, which have been rarely studied. This study aimed to Impacts of antenatal educational interventions base on BASNEF Model on mothers' breastfeeding self-efficacy: a Quasi-experimental study. This was a quasi-experimental study done on 100 nulliparous mothers referred to the selected clinics in Shiraz. Sampling was done by random method. The intervention was held based on BASNEF components in four educational sessions besides a session on cognitive norms, while the control group received the routine education. The mean score of breast-feeding self-efficacy was measured both before and after the intervention by Fax and Dennis questionnaire besides its correlation with child physical developmental indicators. SPSS18 was applied to analyze the data through paired t-test, independent t-test, and Chi-square test. The mean age of participants was 23.86 ± 4.30 and 24.4 ± 4.18 in BASNEF and control groups, respectively. After the intervention, there was a significant difference in the mean score of self-efficacy in the intervention group compared to the control group (p <0/001). In addition, there was a significant positive correlation between breast-feeding self-efficacy and infants' weight at the age of 3 months besides height at the age of 1 and 3 months (p<0.05). BASNEF based breastfeeding training was related to the rise in breastfeeding self-efficacy in nulliparous pregnant women and subsequently improvement of children's physical growth indicators

Preemptive Ibuprofen and Orally Administered Dexamethasone for Prevention of Pain and Swelling following Implant Surgery

Introduction: The post-operative pain and swelling are frequently observed after different surgical procedures. Orofacial pain management is a challenging topic for the dental-medical profession. The main objective of this study was to compare the effects of two designed medical regimens in the context of post-operative management of pain and swelling following simple dental implant surgery. Materials and Methods: In this randomized and double-blinded controlled clinical trial, a total of 39 implants were placed in 31 patients by one clinician. Patients were divided into the test and control groups. Before surgery, each patient in the control group received 1gr of amoxicillin and 400 mgr of ibuprofen, and each one in test group received 1gr of amoxicillin, 400 mgr of ibuprofen and 0.5 mgr of dexamethasone. Antibiotic regimen, together with analgesics and anti-inflammatory treatment was provided after surgery for both groups. Pain was measured using visual analogue scale in days 1, 3 and 6 after surgery. Swelling was evaluated by a verbal scale in day 6. Also, the impact of following factors gender, age, duration of surgery, type and number of implant on pain and swelling was measured by the general linear model analysis. Results: The majority of patients in both study groups reported the pain to be mild, with peak intensity occurring at 24 hours after operation. No significant difference was observed across the groups for any given time. Also, there was no significant difference between two groups regarding their swelling profile. Conclusion: The experiments provide evidence that both of these methods are effective in pain and swelling reduction

Correlation between workplace culture, learning and medication errors

The occurrence of medication errors in intensivecare units can bring about irreparable damageand even lead to death in hospitalized patients.In this respect, numerous investigations have suggestedthat many factors including workplace culture and learningfrom error can affect the incidence rates of such errorsin these units. Accordingly, the present study was to shedlight on the correlation between workplace culture, learningfrom error, and reporting rate of medication errorsamong nurses in intensive care units affiliated to teachinghospitals of Shahid Beheshti University of Medical Sciencesin Iran.Methods: A descriptive-analytical study was conductedamong 120 nurses working in intensive care units in fourteaching hospitals in the city of Tehran. Then, the questionnairesdeveloped by Gulley et al., Rybowiak et al., andWakefield et al. were used to collect the data related toworkplace culture, learning climate, and medication errors.Results: The findings of this study indicated that increasedlearning from error in nurses working in intensivecare units could lower reporting rate of medication errors(r=-0.312, p-value=0.001); there was also a significantrelationship between workplace culture and reportingrate of medication errors, so that enhancing workplaceculture could reduce reporting rate of medication errors(r=-0.239, p-value=0.012).Conclusion: Improving workplace culture via supportingemployee creativity and innovation as well as promotinglearning environment through an employee reward systemalong with avoidance of punishments and reprimands fornurses during the occurrence of errors could be effective inmitigating the incidence rates of medication errors

The effectiveness of oral health education by peers on knowledge and performance of students in Zabol, Iran

Oral diseases are the extensive human diseases, especially among children and more than 99% of people suffer from this disease. Oral and dental education by peers provides a good condition to form the health behaviors before adulthood. The aim of this study was to investigate the effect of oral and dental education by peers on knowledge and behavior of first grade female students in Zabol, Iran.

The validity of the results was determined through expert panel and the reliability was determined by Cronbach`s alpha (N=30, a=0. 77). One person from each class in the intervention group was selected as a peer educator and was educated via an education plate. The post-test was performed after one month of education. For data analysis, descriptive and analytical tests (paired and independent t-test) in SPSS 18 software were used. There was a significant difference between the mean scores of two groups in knowledge and behavior after education, so that the mean score of knowledge and behavior of students who were educated by peers were higher than that of them before education (P<0.001). Oral and dental education of students by peers is a simple, inexpensive, and effective method which can be used by health system, truly

The association of the betatrophin level with metabolic and inflammatory parameters in infertile women with polycystic ovary syndrome: A case-control study

Background: Betatrophin may be associated with metabolic diseases. Objective: To investigate the betatrophin level and its association with metabolic and inflammatory parameters in infertile women with polycystic ovary syndrome (PCOS) and other infertile women during the intrauterine insemination cycle. Materials and Methods: This case-control study was conducted with 90 infertile women (45 with PCOS and 45 without) chosen by convenience sampling, in the infertility clinic of Imam Khomeini Hospital in Tehran, Iran. Participants were interviewed to obtain their age, body mass index, and reproductive history. Fasting brachial venous blood samples were obtained on the 3rd day of the menstrual cycle to measure the levels of betatrophin, fasting blood sugar, insulin, luteinizing hormone, folliclestimulating hormone, low-density lipoprotein cholesterol, estradiol, and high-sensitivity C-reactive protein. Results: The results showed that the level of betatrophin in women with PCOS was significantly higher than in the control group (p = 0.05). Based on multiple linear regression analyses, the effects of metabolic and inflammatory parameters on betatrophin were not significant (p = 0.19). The results showed no significant difference between groups in folliculogenesis (p = 0.57). Conclusion: According to the results, betatrophin levels were higher in infertile women with PCOS than in those without. The findings suggest that there may be an association between increased betatrophin and increased incidence of PCOS. Further studies with a larger sample size are needed to investigate the role of betatrophin in insulin resistance and lipid metabolism, and its effects on infertility treatment outcomes.
