Abstract Introduction Mentoring schemes have been established to mitigate these concerns and improve interest in surgery among medical students; however, there is a paucity of research on whether conventional term-time (CTT) mentoring or more intensive out-of-term (IOT) meaningful promoting surgical careers. Method Most societies the UK offer CTT (ca. one-to-three during academic year) their me...

introduction: treatment in chronic constipation is highly dependent on colon transit time (ctt), which not only determines the cause but also determines the correct treatment policy. the aim of this study was evaluation of ctt in constipated patients. methods: 43 patients with chronic constipation who did not respond to high fiber diet were enrolled in the study. patients with history of drug i...

Two widely used problems are the Satisfiability problem (SAT) and the Curriculum-Based Course Timetabling (CB-CTT) problem. The SAT problem searches for an assignment that make true a certain boolean formula. On the other side, the CB-CTT involves the task of scheduling lectures of courses to rooms, considering teacher availability, a specified curricula, and a set of constraints. Given the adv...

Outgoing longwave radiation (OLR) data are one of the key factors in studying balance earth–atmosphere system East Asia. It is great significance to explore influence on OLR. This paper processes nearly 19 years, from September 2002 February 2022, and conducts in-depth research using exponential smoothing method, empirical orthogonal decomposition (EOF), correlation analysis, other methods. We ...

abstract  background: at present, differentiation between exudative and transudative pleural  effusion is based solely on laboratory measures and is time-consuming. asimple  bedside method would be of great help to differentiate between these two types of effusions.  we present a new method for this purpose assessed in 46 patients.  methods: standard laboratory tests and our method were tested ...

BACKGROUND Although health-related quality of life (HRQOL) instruments may offer satisfactory results, their length often limits the extent to which they are actually applied in clinical practice. Efforts to develop short questionnaires have largely focused on reducing existing instruments. The approaches most frequently employed for this purpose rely on statistical procedures that are consider...
