Twelve men who had been exposed to a minor asbestos hazard have been examined clinically, radiologically, and physiologically, and an assessment of the airborne asbestos concentration has also been made. Ten men had worked in a transformer department lagging transformer windings with asbestos paste for between IS and 37 years. Two of these men showed minor radiological and minor physiological c...

For spruce (Picea abies (L.) Karst.), as with most other species, the value of a log is to great extent determined by its defects. That is the reason why sawyers, aiming at the optimal utilization of a log, were naturally interested in defects, their number, position and shape. X-ray computer tomography (CT) scanning is able to detect internal density variations related to defects. In order to ...

The quality of grey alder logs (Alnus incana) was studied by sawing sample logs from two different forests in November 1995–February 1996. For grading of grey alder logs and sawn timber the proposed system of Keinänen and Tahvanainen (1995) plus the reject -grade was used. In general, grey alder logs have knots from the base to the top. All types of knots appear, and the length of the knot-free...

This paper explores live coding environments in the context of notational systems. The improvisational practice of live coding as combining both composition and performance is introduced and selected systems are discussed. The author’s Threnoscope system is described, but this is a system that enables the performer to work with both descriptive and prescriptive scores that can be run and altere...

In this paper, we present some preliminary studies on reducing the emittance of the Hefei light source II (HLS-II) storage ring by redistributing the synchrotron damping partition factor using a Robinson wiggler. The studies demonstrate that it is possible to reduce the emittance by 50% using a 2-meter long wiggler on a rematched lattice. This encouraging result suggests a feasible option to si...

Growth stresses are usually present in the fast-growing trees of forest plantations and can be evaluated along stem diameter. relaxed after tree felling during sawing drying, manifested lumber quality. Different methods have been employed to reduce effect growth stresses, such as steaming heating treatments. Excellent yield Hyeronima alchorneoides were observed, but they showed difficulties pri...
