Another string.... but no bow.

چکیده
Based on a positive personal experience, the authors advocate the use of a wound protector/retractor such as the Alexis system in total hip arthroplasty, to avoid intra-operative bacterial contamination from the skin, while avoiding damage to the skin and other soft tissues.

Observations on the violin bow and the interaction with the string
The bow influences a string performance in two principal ways: ( I ) by adding to the sound quality, primarily set by the violin body, and (2) by serving as the tool through which tones andphrases are formed. The influence on tone quality has been attributed to a modulation of either the relative velocity between bow and string, or the bow pressure, due to the resonances of the bow. New results...
متن کاملMechanics and acoustics of violin bowing Freedom, constraints and control in performance
This thesis addresses sound production in bowed-string instruments from two perspectives: the physics of the bowed string, and bow control in performance. Violin performance is characterized by an intimate connection between the player and the instrument, allowing for a continuous control of the sound via the main bowing parameters (bow velocity, bow force and bowbridge distance), but imposing ...
متن کاملEffect of the Width of the Bow Hair on the Violin String Spectrum
Violinists often claim that tilting the bow provides greater brilliance. By tilting, the effective width of the bow hair is reduced and the bow force distribution across the bow hair ribbon is changed. Considering that the width of the bow hair of a violin bow is roughly 1/32 of the string length (about 10 mm), and that the relative bow-bridge distance in playing typically varies between 1/8 an...
متن کاملCoordination in Fast Repetitive Violin-Bowing Patterns
We present a study of coordination behavior in complex violin-bowing patterns involving simultaneous bow changes (reversal of bowing direction) and string crossings (changing from one string to another). Twenty-two violinists (8 advanced amateurs, 8 students with violin as major subject, and 6 elite professionals) participated in the experiment. We investigated the influence of a variety of per...
متن کاملSome aspects of bow resonances - conditions for spectral influence on the bowed string
The dynamics of the frictional force between the bow hair and the string causes the bow to oscillate in its longitudinal direction during the bow stroke. Under certain conditions, such oscillations in the bow enhanced by the bow resonances can be observed in the spectrum of the frictional force between bow and string, and also in the velocity spectrum at the bridge. The present study discusses ...
