OBJECTIVES to determine (cost)-effectiveness of a stepped-care intervention programme among subjects ≥ 75 years who screened positive for depressive symptoms in general practice. DESIGN the pragmatic cluster-randomised controlled trial with 12-month follow-up. SETTING sixty-seven Dutch general practices. SUBJECTS two hundred and thirty-nine subjects ≥ 75 years screened positive for untrea...

Abstract A hydraulic-stepped spillway was designed using an aeration basin to provide aerated flow the stepped utilizing a hydraulic jump. However, through entrance of might separate from first step top and impact downstream steps at large unit discharge, causing so-called jet flow. new experimental study conducted better understand in hydraulic-jump-stepped with comparisons conventional spillw...

The interpretation of structure in cusp ion dispersions is important for helping to understand the temporal and spatial structure of magnetopause reconnection. “Stepped” and “sawtooth” signatures have been shown to be caused by temporal variations in the reconnection rate under the same physical conditions for different satellite trajectories. The present paper shows that even for a single sate...

During the last three decades, the introduction of new construction materials (e.g. RCC (Roller Compacted Concrete), strengthened gabions) has increased the interest for stepped channels and spillways. However stepped chute hydraulics is not simple, because of different flow regimes and importantly because of very-strong interactions between entrained air and turbulence. In this study, new air-...

CONTEXT Given the public health significance of late-life depression and anxiety, and the limited capacity of treatment, there is an urgent need to develop effective strategies to prevent these disorders. OBJECTIVE To determine the effectiveness of an indicated stepped-care prevention program for depression and anxiety disorders in the elderly. DESIGN Randomized controlled trial with recrui...

BACKGROUND Stepped wedge cluster randomised trials introduce interventions to groups of clusters in a random order and have been used to evaluate interventions for health and wellbeing. Standardised guidance for reporting stepped wedge trials is currently absent, and a range of potential analytic approaches have been described. METHODS We systematically identified and reviewed recently publis...

OBJECTIVE The authors compared the incremental cost-effectiveness of a stepped-care, multicomponent program with usual care for the treatment of depressed women in primary care in Santiago, Chile. METHOD A cost-effectiveness study was conducted of a previous randomized controlled trial involving 240 eligible women with DSM-IV major depression who were selected from a consecutive sample of adu...

Self-sustained instabilities and pseudo-periodic motion may be observed in hydraulic structures and industrial flows. Documented examples include the hydraulic jump, sloshing motion in a reservoir and surging waves in pooled stepped spillways. The instabilities may generate some very large turbulence levels and integral turbulent scales, combining the contributions of both slow fluctuations and...

This study evaluated some mechanical parameters of Z250 composite resin using different light-curing methods. Ten specimens were prepared for each mechanical test group with different dimensions according to the test. Light-curing was performed by: a). continuous light (800mW/cm²-40s); b). exponential light (0-800mW/cm²-40s); c). intermittent light (2s-600mW/cm²; 2s without light-80s); d). step...

Electric field pulse bursts generated by lightning flashes are considered as sources of high radio frequencies. In this study, an analysis of pulse bursts in electric field records of 30 negative cloud to ground lightning flashes recorded in the southern coastal area of Sri Lanka is presented. Sixty-four percent (64%) of pulse bursts are typical chaotic pulse trains (CPT). Twenty-four percent (...
