Hermite-Hadamard type inequalities for operator geometrically convex functions

In this paper, we introduce the concept of operator geometrically convex functions for positive linear operators and prove some Hermite-Hadamard type inequalities for these functions. As applications, we obtain trace inequalities for operators which give some refinements of previous results.Comment: Accepted for publishing in Monatshefte fur Mathemati

Some Hermite-Hadamard type integral inequalities for operator AG-preinvex functions

In this paper, we introduce the concept of operator AG-preinvex functions and prove some Hermite-Hadamard type inequalities for these functions. As application, we obtain some unitarily invariant norm inequalities for operators

Developing an intervention program based on attachment to God and investigating its effectiveness on ineffective spiritual schemas and spiritual well-being

Background and Aim: Inefficient spiritual patterns of our adaptation to God's laws cause problems in the society in living environments, the present study aims to formulate an intervention program based on attachment to God and examine its effectiveness on ineffective spiritual patterns and spiritual well-being. Methods: From a methodological point of view, the current research was a quasi-experimental research design with a pre-test-post-test with a control group. The statistical population of this research was made up of all employees of Continental Plateau Oil Company in 2019. The sample of this study was 60 people who were randomly selected in two experimental and control groups (20 people in each subgroup) based on the criteria of entering and exiting the study. The research tool was the questionnaire of ineffective spiritual schemas, attachment to God and spiritual well-being, which was completed by all participants in the pre-test and post-test phases. God attachment sessions were held for experimental group participants in nine 120-minute sessions, while control group participants did not receive any intervention. Research data were analyzed using multivariate analysis of covariance and using SPSS-22 software. Results: The results showed that the intervention based on the quality of attachment to God has an effect on all the components of ineffective spiritual schemas and spiritual well-being (P<0.01). Conclusion: According to the results of this study, the intervention based on the quality of attachment to God led to the improvement of all the components of ineffective spiritual schemas and spiritual well-bein

Molecular characterization and antimicrobial resistance of nasal Staphylococcus aureus in the community of Kabul

ABSTRACT: Objectives: This study aimed to investigate the prevalence and molecular characteristics of community methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage among students at Kabul University. Methods: Nasal swabs were collected from anterior nares of 150 healthy non-medical students at Kabul University. Antimicrobial susceptibility testing was performed on all S. aureus isolates, and all detected MRSA isolates were then confirmed by mecA/mecC polymerase chain reaction and characterized using DNA microarray. Results: A total of 50 S. aureus strains were isolated from the anterior nares of the 150 participants. The prevalence of S. aureus and MRSA nasal carriage among Kabul students was 33.3% and 12.7%, respectively. Seven (36.8%) MRSA isolates and 8 (25.8%) methicillin-susceptible S. aureus (MSSA) isolates were multidrug-resistant (i.e. resistant to at least three different antimicrobials tested). All MRSA isolates (n = 19) were susceptible to linezolid, rifampicin, and fusidic acid. Seven MRSA clones, belonging to four clonal complexes (CCs), were identified. The most commonly identified clone was CC22-MRSA-IV TSST-1-positive, which accounted for 63.2% (12/19) of MRSA isolates. SCCmec typing showed that most MRSA strains harboured SCCmec type IV (94.7%). Thirteen (68.4%) MRSA isolates carried the TSST-1 and 5 (26.3%) PVL genes. Conclusion: Our findings revealed the relatively high prevalence of MRSA nasal carriers in the community in Kabul, with the predominance of the CC22-MRSA-IV TSST-1-positive clone and frequent multidrug resistance among these isolates
