The topic of wind-clumping has been the subject of much activity in recent years, due to the impact that it can have on derived mass-loss rates. Here we present an alternative method of investigating wind-clumping, that of polarimetry. We present simulations of the polarization produced by a clumpy wind, and argue that the observations may be reproduced just by statistical deviations from spher...

This paper describes an experimental investigation conducted on WRS-BTU seismic isolators that are constituted by a wire rope spring coupled with a ball transfer unit. The device can be considered rigid along the vertical direction while the horizontal stiffness can be independently chosen to shift the natural period away from the period range having the most of earthquake energy. Two kinds of ...

The SMC harbours a class of hot nitrogen-sequence Wolf-Rayet stars (WNE) that display only relatively weak broad emission lines. This indicates low mass-loss rates and makes them also hard to detect. However, such stars are possible emitters of strong He Lyman continua that in turn could ionize observable He iii regions, i.e. highly excited H ii regions emitting nebular He iiλ4686 emission. We ...

UNLABELLED Recent studies have shown that stimulation of cannabinoid 1 (CB1) receptor reduces the area of ischemic myocardial necrosis and affects activity of the digestive tract. The aim of the present study was to check whether the administration of CB1 receptor agonist or antagonist affects the stress-induced gastric ulceration and development of edematous pancreatitis. METHODS Experiments...

Abstract A transition to renewable energy is needed mitigate climate change. In Europe, this has been led by wind energy, which one of the fastest growing sources. However, demand and production are sensitive meteorological conditions atmospheric variability at multiple time scales. To accomplish required balance between these two variables, critical high low supply must be considered in design...

BACKGROUND AND OBJECTIVES Empirical evidence is needed to assess clinical appropriateness of any new surgical device or material. Differences in surgical outcomes between Vicryl figure-of-8 and V-Loc barbed sutures for vaginal cuff closure during robotic hysterectomy were assessed. METHODS We examined the electronic medical records of 202 patients who underwent scheduled robotic-assisted tota...

BACKGROUND There is a poorly understood relationship between Leadership WalkRounds (WR) and domains such as safety culture, employee engagement, burnout and work-life balance. METHODS This cross-sectional survey study evaluated associations between receiving feedback about actions taken as a result of WR and healthcare worker assessments of patient safety culture, employee engagement, burnout...
