Different flow patterns of downward gas-liquid two-phaseflow using simple mixer are studied in an experimental manner. An experimental setup is designed and fabricated to allow the visual observation of downward two-phase flow patterns and their transitions. The flow patterns are recorded by a 1200 frames per second high speed video camera. The quality of downward two-phase flow patterns photos...

BACKGROUND Randomised controlled trials (RCTs) are the gold standard for evaluating treatment efficacy. However, the outcomes of RCTs often lack clinical utility and usually do not address real-world effectiveness. AIMS To review how traditional RCTs may be triangulated with other methodologies such as observational studies and pragmatic trials by highlighting recently reported studies, outco...

The present research uses a behavioral observation methodology to examine emotional and behavioral reactions to threatening interpersonal situations in married couples. The research shows that although anxious attachment can hinder people's tendencies to react constructively to threatening events, greater relationship commitment may serve as a buffer against the negative effects associated with...

The basic idea of this research – to learn from those who have escaped poverty – is very interesting and potentially very valuable. The question is how to ensure that this potential is fully realized. There are of course many aspects to this. In these comments, I focus on two broad points. The first has to do with the balance between retaining the richness and insight of qualitative research an...

A longitudinal, repeated-measures design with intervention and comparison groups was used to evaluate the effect of a training curriculum based on TeamSTEPPS with video vignettes focusing on fall prevention. Questionnaires, behavioral observations, and fall data were collected over 9 months from both groups located at separate hospitals. The intervention group questionnaire scores improved on a...

[Purpose] Several action observation/imagery training studies have been conducted in patients with limited physical activity showing improvements in motor function. However, most studies compared effects of action observation and imagery, so little is known about the changes caused by subsequent observation of target objects. Moreover, few studies analyzed brain wave changes in the EEG mu rhyth...
