The influence of the HBT effect on the multiplicity distribution and charge ratios of independently produced pions is studied. It is shown that, for a wide class of models, there is a critical point, where the average number of pions becomes very large and the multiplicity distibution becomes very broad. In this regime unusual charge ratios (”centauros”, ”anticentauros”) are strongly enhanced. ...

A two-dimensional hydrodynamic model for a bounded plasma cylinder is developed. This model establishes a bridge between the two limiting cases presented by Godyak and Sternberg (2008 Plasma Sources Sci. Technol. 17 0250042): the diffusion-controlled regime and the free-fall regime. An analysis of the bounded plasma cylinder with arbitrary aspect ratios and arbitrary collisionality is presented...

We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid ...

The question of human resources is central to the success of VISION 2020 and of any health programme. The VISION 2020 global initiative document clearly spelt out what personnel was required and, more recently, the World Health Organization document on human resources for health care made recommendations on the type and number of people needed in order to meet all our objectives in global healt...

The purpose of this article is to introduce non-verbal tools as a way to initiate the psychosocial support response after a major disaster. The psychosocial interventions that follow the application of the Non Verbal Tool in its different configurations are based on the principle of fostering and strengthening the social and psychological attributes among the community members. The various psyc...

Family caregivers of persons following neurotrauma function as de facto extensions of our health care system. Their challenges may result in negative consequences for their physical and mental health, which directly impacts the well-being of their care-recipient. In this paper, we survey current practices in providing caregiver support, outline considerations for developing collaborative interv...

Objective The individually delivered Supervising for Home Safety (SHS) program improves caregivers' injury-related beliefs and supervision practices. The current randomized controlled trial used a group delivery in a community setting and assessed program impact, feasibility, and acceptance. Methods Caregivers of 2-5-year-olds were randomized to receive either the SHS or an attention-matched ...

The new class of wrought γ-γ/ Co-base superalloys, which are based on Co-Al-W system,  was developed by conventional hot working routes with a high volume fraction of γ/ precipitates and good mechanical properties. The aim of the present study was to predict the flow stress and hot deformation modeling of a novel γ-γ/ Co-base superalloy. The hot compression test...
