VAGVERKET (Swedish National Road Admlnlstratlon. SNRA) Is a decentralized organJzation with a number of regional units sharing many slmilarlties. EDP support shall enable an efY!clent information supply throughout the entire organJzation through widespread usage of common data. Data Includes both data structurable In tables as well as different documents. Data Is considered to be an Integrated ...

The ability of two mineral trioxide aggregate (MTA) compounds and Intermediate Restorative Material (IRM) to seal large furcation perforations were evaluated using a dye-extraction leakage method. The furcation perforations were repaired with and without the use of internal matrix before placement of repair material. Eighty extracted human mandibular first molars were divided into positive (n =...

In multimedia networks, performance management is required to ensure that the agreed quality of service (QoS) is sustained. To detect possible QoS degradation and locate the cause of the degradation, end-to-end QoS monitoring is not sufficient. Instead, QoS distribution, the distribution of QoS experienced by a real-time flow in different network segments, should be monitored. However, few of c...

A low-energy (50 kV) X-ray tube used for the stereotactic irradiation of intracranial lesions has been in use since 1999. The unit is calibrated prior to every procedure and during periodic quality assurance (QA) tests. The unit uses an internal and an external scintillation detector to monitor dose as well as a conventional timer. The records of these calibrations were reviewed to see whether ...

Many animals that locomote by legs possess adhesive pads. Such organs are rapidly releasable and adhesive forces can be controlled during walking and running. This capacity results from the interaction of adhesive with complex mechanical systems. Here we present an integrative study of the mechanics and adhesion of smooth attachment pads (arolia) in Asian Weaver ants (Oecophylla smaragdina). Ar...

The aim of this study was the comparative evaluation of inflammatory reactions and tissue responses to four growth factors, or mineral trioxide aggregate (MTA), or a zinc-oxide-eugenol-based cement (IRM) as controls, when used for the repair of furcal perforations in dogs' teeth. Results showed significantly higher inflammatory cell response in the transforming growth factorβ1 (TGFβ1) and zinc-...

SYNOPSIS. Many animals that locomote by legs possess adhesive pads. Such organs are rapidly releasable and adhesive forces can be controlled during walking and running. This capacity results from the interaction of adhesive with complex mechanical systems. Here we present an integrative study of the mechanics and adhesion of smooth attachment pads (arolia) in Asian Weaver ants (Oecophylla smara...

PURPOSE This study was performed to retrospectively evaluate treatment of deep caries in primary molars with formocresol pulpotomy (FP) and indirect pulp therapy (IPT). METHODS 133 primary molars with deep caries approaching the pulp were treated with FP (N = 78) or IPT (N = 55) and followed 2-7 years. All IPTs received immediate stainless steel crowns (SSCs); 61 FPs got an immediate SSC, 13 ...

La tumeur de buschk loewenstein (TBL) ou condylome acuminé géant est une MST à papilloma virus humain, elle est rare est toujours précédée du condylome acuminé. Cette tumeur épithéliale se caractérise essentiellement par son taux important de récidive, par son potentielle de transformation maligne et par son extension en profondeur. Nous présentons un cas d'un patient âgé de 52 ans, sans antécé...

The influence of Na+, Ca2+, La3+, and Fe3+ on the adhesion of Pseudomonas fluorescens H2 and H2S was investigated with interference reflection microscopy (IRM). IRM is a light microscopy technique which allows (i) visualization of the adhesive sites of living bacteria as they attach to a glass cover slip surface and (ii) evaluation of the bacterium-glass surface separation distance within a ran...
