Penetrating injuries in dogs and cats: a study of 16 cases

The objective of this retrospective study was to assess radiographical and surgical findings, surgical management and outcome of penetrating injuries in dogs and cats by evaluating patient records. Sixteen patients were identified (15 dogs and one cat), four with gunshot wounds, and 12 with fight wounds (11 with bite wounds, one struck by a claw). The thoracic cavity was affected in six patients, the abdominal cavity in three cases. Both cavities were affected in five dogs and the trachea in two cases. All of the patients with fight wounds were small breed dogs. Multiple injuries to internal organs that required intervention were found surgically after gunshot wounds and a high amount of soft tissue trauma requiring reconstruction was present after fight wounds. Radiography diagnosed body wall disruption in two cases. All of the affected thoracic body walls in the fight group had intercostal muscle disruptions which was diagnosed surgically. Fourteen patients survived until discharge and had a good outcome. In conclusion, penetrating injuries should be explored as they are usually accompanied by severe damage to either the internal organs or to the body wall. A high level of awareness is required to properly determine the degree of trauma of intercostal muscle disruption in thoracic fight wounds

Three-dimensional sound intensity measurements using microflown particle velocity sensors

This paper reports on a novel method to measure three-dimensional sound intensity and the fabrication of a miniature three-dimensional sound intensity probe. Verifying measurements where performed with three separate micromachined particle velocity probes and one pressure microphone. A three-dimensional sound intensity probe has been realised based on a three-dimensional micromachined particle velocity microphone, a 3D Microflown, and a miniature pressure microphon

A source path contribution analysis on tire noise using particle velocity sensors

Road tire noise is an important topic of research where acoustic particle velocity based testing techniques can be expected to bring new insights. Modal analysis can be carried out using non contact particle velocity sensors, and PU sound probes can be used to measure the radiated sound without a need to use anechoic testing conditions. A further breakdown of the overall sound pressure levels measured in to its various sources can be made by applying a source path contribution analysis, using the PU probes to measure velocity, sound intensity and, for determining the reciprocal transfer path, the sound pressure. The concept of using this type of transfer path analysis will be outlined and illustrated by a tire noise case

Spectrally Similar Incommensurable 3-Manifolds

Reid has asked whether hyperbolic manifolds with the same geodesic length spectrum must be commensurable. Building toward a negative answer to this question, we construct examples of hyperbolic 3–manifolds that share an arbitrarily large portion of the length spectrum but are not commensurable. More precisely, for every n ≫ 0, we construct a pair of incommensurable hyperbolic 3–manifolds Nn and Nµn whose volume is approximately n and whose length spectra agree up to length n. Both Nn and Nµn are built by gluing two standard submanifolds along a complicated pseudo-Anosov map, ensuring that these manifolds have a very thick collar about an essential surface. The two gluing maps differ by a hyper-elliptic involution along this surface. Our proof also involves a new commensurability criterion based on pairs of pants

Evaluatieonderzoek systeemtoezicht op kwaliteit en veiligheid in de zorg

__Abstract__ Al jaren wordt nagedacht over de vraag in hoeverre zorginstellingen zelf in staat zijn om te waarborgen dat zij veilige en kwalitatief zorg leveren. Er is wetgeving die voorschrijft dat zorginstellingen alleen kunnen worden toegelaten als zij een aantal organisatorische zaken op orde hebben. In 1996 is in de Kwaliteitswet geregeld dat zorginstellingen zelf de kwaliteit van de zorg systematisch moeten bewaken, beheersen en verbeteren. Bestuurders en Raden van Toezicht zijn in eerste instantie zelf verantwoordelijk voor de kwaliteit van zorg in hun instelling, waarbij zij zorg dragen voor passende procedures en cultuur. De veronderstelling is dat als zorginstellingen deze verantwoordelijkheid opnemen en daadwerkelijk waarmaken, het overheidstoezicht op de naleving beperkt kan worden tot toezicht op (de werking van) het zelf opgezette ‘systeem’ om kwaliteit en veiligheid te borgen en risico’s te beheersen. Deze manier van inspecteren wordt in Nederland Systeem Toezicht (ST) genoemd
