BACKGROUND In postgraduate training, there is a need to continuously assess the learning and working conditions to optimize learning. Students or trainees respond to the learning climate as they perceive it. The Dutch Residency Educational Climate Test (D-RECT) is a learning climate measurement tool with well-substantiated validity. However, it was originally designed for Dutch postgraduate tra...

AIM Boor et al developed and validated the questionnaire D-RECT (Dutch Residency Educational Climate Test ) to measure the clinical learning environment within the medical specialist training. In this study, a German version of this questionnaire (D-RECT German) is analyzed regarding testtheoretical properties. PROBLEM Are the results of Boor et al replicable as a proof for validity of the qu...

The aim of this study was to carry out geometric and dosimetric evaluation of the usefulness of a deformable image registration algorithm utilized for adaptive head-and-neck intensity-modulated radiotherapy. Data consisted of seven patients, each with a planning CT (pCT), a rescanning CT (ReCT) and a cone beam CT (CBCT). The CBCT was acquired on the same day (± 1 d) as the ReCT (i.e. at Fractio...

BACKGROUND A department's learning climate is known to contribute to the quality of postgraduate medical education and, as such, to the quality of patient care provided by residents. However, it is unclear how the learning climate is perceived over time. OBJECTIVES This study investigated whether the learning climate perceptions of residents changed over time. METHODS The context for this s...

BACKGROUND Few pre-hospital services have the possibility to accurately measure core temperature (T core). Non-invasive estimation of T core will improve pre-hospital decision-making regarding the triage and management of hypothermic patients. Thermistor-based tympanic temperature (T tymp) correlates well with T core in controlled studies; however, little is known about the feasibility of using...

Single-stranded DNA (ssDNA) recombineering is a technology which is used to make subtle changes in the chromosome of several bacterial genera. Cells which express a single-stranded DNA binding protein (RecT or Bet) are transformed with an oligonucleotide which is incorporated via an annealing and replication-dependent mechanism. By in silico analysis we identified ssDNA binding protein homologs...

OBJECTIVES To assess the learning environment of the Saudi psychiatry board program using the Dutch Residency Educational Climate Test (D-RECT) and to explore residents' perception of different domains of the learning environment. Methods: This was a descriptive cross-sectional study. The D-RECT instrument was distributed to all residents at all training sites of the Saudi psychiatry training p...

We report the identification and functional analysis of nine genes from Gram-positive and Gram-negative bacteria and their phages that are similar to lambda (lambda) bet or Escherichia coli recT. Beta and RecT are single-strand DNA annealing proteins, referred to here as recombinases. Each of the nine other genes when expressed in E. coli carries out oligonucleotide-mediated recombination. To o...

We relate two complexity notions of bipartite graphs: the minimal weight biclique covering number Cov(G) and the minimal rectifier network size Rect(G) of a bipartite graph G. We show that there exist graphs with Cov(G) ≥ Rect(G). As a corollary, we establish that there exist nondeterministic finite automata (NFAs) with εtransitions, having n transitions total such that the smallest equivalent ...

The use of wire-coils is especially relevant at low Reynolds numbers (below the critical number to turbulent flow in smooth tubes) according its inherent positive features such as advance transition onset and, if they present suitable geometric characteristics, establishment an extended transitional a interval [ReCL-ReCT], with predictable friction coefficient and Nusselt number. This paper pre...
