Snoring and the role of the GDP: British Society of Dental Sleep Medicine (BSDSM) pre-treatment screening protocol.

Snoring is not necessarily a benign condition; it can be linked to the serious condition obstructive sleep apnoea (OSA). In some cases mandibular repositioning devices can be an effective treatment for simple snoring and mild to moderate sleep apnoea, and these devices can be provided by dentists (with appropriate training and in line with Dental Protection Ltd guidelines). Until now, the dental profession has not been given any guidance on how to differentiate between patients who may be treated without further reference to medical colleagues (ie simple snorers), and those who should be referred for specialist assessment. The aim of this paper is to facilitate safe treatment of snoring and OSA and to protect dentists by explaining an accepted method for screening patients for obstructive sleep apnoea

Transient behaviour of deposition of liquid metal droplets on a solid substrate

International audienceThis paper investigates the mechanisms that contribute to the spreading of liquid metal macro-drop deposited during Stationary Pulsed Gas Metal Arc Welding on an initially cold solid workpiece. Surface tension and inertial effects take an important part in the behaviour of the liquid metal macro-drop, but in this configuration the influence of energetic effects can also be significant. The experimental results are discussed in the light of dimensional analysis in order to appreciate the influence of the process parameters and the physical mechanisms involved on the spreading of a macro-drop. A law is established to model forced non-isothermal spreading
