BACKGROUND Artificial calcanei, fresh-frozen cadaver specimens, and embalmed cadaver specimens were compared in experimental testing under biocompatible loading to clarify the biocompatibility of artificial calcaneal specimens for implant testing. METHODS Two different artificial calcaneal bone models (Sawbone, Pacific Research Laboratories, Vashon, WA, and Synbone, Synbone Inc., Davos, Switz...

This paper reports on a user-centred evaluation of search process characteristics within a thesaurus-enhanced search environment and the ways in which these characteristics affect users’ judgment of search terms and results. The study has addressed the questions relating to the types of search moves and the relationship between search moves and search terms and results. Résumé : Cet article pré...

Psoriasis is a complex inflammatory disease, and in women the incidence is high in child-bearing years. Treatment during pregnancy presents genuine challenges since management requires adequate assessment of the extent of disease, comorbidity, and potential risk to the fetus. Scientific evidence is scarce on the effects that certain drugs have on fetal development given the ethical concerns abo...

Ce document compare l’état de santé des immigrants et leur utilisation des services de santé à ceux de la population d’origine canadienne à l’aide de données provenant de deux cycles (1985 et 1991) de l’Enquête sociale générale (ESG). Les résultats obtenus démontrent que l’état de santé des immigrants de même que leur utilisation des services de santé ne sont pas significativement différents de...

RESUMEN. Presencia de Listeria monocytogenes en vegetales frescos. Introducción. En los últimos años, se ha dado un incremento en el hecho de consumir vegetales frescos como parte de una dieta sana, pero no se puede descartar el que estos pueden actuar como vehículos de microorganismos patógenos, como Listeria monocytogenes. Material y métodos. Se evaluó la presencia de Listeria monocytogenes e...

Background. The class on complexity goes through how to design a fixed block size motion estimator. It is useful to have reviewed that class before proceeding with this document. Basically, often in video the only difference between much of the content in subsequent frames is motion (imagine panning a camera slowly over a fixed scene). If this is true the difference between subsequent frames ca...

Theories of organizational culture and climate (OCC) applied to child welfare systems hypothesize that strategic dimensions of organizational culture influence organizational climate and that OCC explains system variance in youth outcomes. This study provides the first structural test of the direct and indirect effects of culture and climate on youth outcomes in a national sample of child welfa...

The effect of grain angle (GA) on shear strength of Douglasfi r has been evaluated. Shear block specimens with a GA varying from 0 to 90 ° was loaded in the shear plane, resulting in failure mode transitioning from parallel to grain shear to rolling shear. As expected, shear strength decreased as the GA increased from 0 ° to 90 ° . A root-mean-square equation was found to be suitable to predict...

The use of fixed-block error recovery, which combines frequent validation and partial recomputation, to address the problem of transient faults in elliptic curve scalar multiplication was proposed earlier and its advantages in terms of efficiency and reliability were illustrated. However, in order to maximize its advantages, the selection of the block size has to be optimized, which requires kn...

AMULET1, developed in the OMI-MAP project, showed that complex asynchronous design is feasible. AMULET2e, developed in the OMI-DE project, is the next step in establishing self-timed processing as a commercially viable technology. It incorporates a new core, AMULET2, which is significantly faster than AMULET1, together with on-chip RAM which can be configured as a fixed block of RAM or as a cac...
