NMR methods have been applied to evaluation of prototropic tautomerism, N (1)H ^ N (3) H. in several selected pyrimidines, viz. the neutral forms of isocytosine and 2-alkylthiopyrimidone-4, and the monoanionic forms of uracil, 5-fluorouracil and 4-thiouracil. The predominant tautomeric species of the neutral forms could be estimated only qualitatively from chemical shifts. For the monoanionic f...

In this study we report about two novel azomethine–BODIPY dyads 1 and 2. The two dyads have been, respectively, synthesized by covalent tethering of tautomeric ortho-hydroxy aromatic azomethine moieties including N-salicylideneaniline (SA) and N-naphthlideneaniline (NA) to a BODIPY fluorophore. Both of the two dyads 1 and 2 show enol-imine (OH) structures dominating in the crystalline state. Dy...

conclusions as a result of this study, it was found that critical care nurses with fixed shift schedules display more burnout in emotional exhaustion dimension, compared to those working with rotating shift schedules. results most of the participants were females (62.7%), aged between 22 - 29 years (38.5%), married (59.2%), and had a bachelor degree (86.9%). the mean score of emotional exhausti...

  Abstract   Background: Irregular Working hours, including night work and shift work, have been   found to be associated with alteration in various levels of biochemical factors. And some studies have showed association between shift work and blood biochemical disturbances in blood. In this epidemiological study we investigated, whether regular schedule of working hours can minimize the associ...

a bstract background: some health problems are more prevalent in shift workers than day workers. musculoskeletal disorders are considered as one of the most common health-related problems that can cause disability among health care workers. the aim of this study was to assess the associations between shift working and the prevalence of musculoskeletal symptoms (mss) among nursing personnel. mat...

in this paper, a bayesian approach is proposed for shift point detection in an inverse gaussian distribution. in this study, the mean parameter of inverse gaussian distribution is assumed to be constant and shift points in shape parameter is considered. first the posterior distribution of shape parameter is obtained. then the bayes estimators are derived under a class of priors and using variou...

Background: Today, obesity is considered as a health problem that increases the risk of some diseases. Therefore, identifying the effective factors on obesity is of great importance. Shift work is one of the indicators for increased risk of obesity in society and also shift work may cause various health problems for workers in military organizations. The current study aimed to investigate the r...
