PURPOSE This study assessed the association between eye symptoms (enophthalmos or diplopia) and site of damage, volume, deviated inferior rectus muscle (IRM) and type of fracture with computed tomography (CT). The intent is to anticipate the prognosis of orbital trauma at initial diagnosis. METHODS Forty-five patients were diagnosed with fractures of the inferior wall of one orbit. Fracture a...

[1] The ‘‘hard’’ isothermal remanent magnetization (HIRM) and the S-ratio are widely used in environmental magnetism to quantify the absolute and relative concentrations, respectively, of antiferromagnetic minerals (hematite and goethite) in mineral mixtures. We demonstrate that synthetic Al-substituted hematite and goethite exhibit a wide range of coercivities, which significantly influences t...

OBJECTIVES To evaluate in vitro the effect of cavity preparation with microburs and diamond-coated ultrasonic tips on the microleakage and marginal fit of six end-root filling materials. STUDY DESIGN. The following materials were assessed: amalgam (Amalcap), zinc oxide eugenol (IRM), glass ionomer (Vitrebond), compomer (Cavalite), mineral particle aggregate (MTA) and composite (Clearfil). Cavit...

u cours des dix dernières années l’IRM mammaire a trouvé sa place en tant que technique complémentaire à la mammographie et à l’échographie dans le diagnostic, le bilan d’extension locale et le suivi thérapeutique des lésions intra mammaires (1-3). Dans une publication récente à propos de 995 lésions, la sensibilité et la valeur prédictive négative de l’IRM ont été respectivement de 97 % et 94 ...

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...
