Objectives: The aim of this study was to compare the microtensile bond strengths (µ TBS) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. Methods: Three core materials (Nulite F® (Biodental Technologies), Filtek Z250® (3M-ESPE), Prettau-Anterior® (Zirkonzhan, Germany)) were prepared as blocks (10×10×4 mm3) according...

......As guest editors of this IEEE Micro special issue and co-chairs of the selection committee, it’s our pleasure to introduce the ninth annual edition of IEEE Micro’s Top Picks from the Computer Architecture Conferences. In recent years, Top Picks has rapidly become a tradition in the computer architecture community, an important recognition of research excellence, and a great opportunity to...

This paper describes a working prototype device, PopCAD, for straightforward, tangible 3-dimensional input and design. PopCAD is a paper-based pop-up computational artifact that can be carried about easily and unfolded into its "working" instrumental form. When unfolded, PopCAD allows the user to switch on LED lights in a 3D spatial array; the positions of these lights are sent to a desktop com...

The effects of prior chronic exposure to atrazine on responses to subsequent acute exposures were investigated using a common benthic diatom. Clonal, axenic cultures of Craticula cuspidata were established from the Platte River (Nebraska) and obtained from a culture collection (unlikely prior exposure to atrazine). All cultures received a chronic 67-d treatment of 1 mg/L atrazine, and growth wa...

A typical learning method using the Internet is exploratory learning, where learners construct knowledge through exploring the web autonomously. A problem with web-based exploratory learning is a learning impasse caused by inadequate hyperlinks. MITS, an adaptive web-based learning system, has been developed in order to avoid this learning impasse. This system contains a freehyperlink environme...

With the aid of actuators energy fluxes and mass or volume flows can be controlled electrically. Microactuators distinguish themselves by dimensions in the range of millimetres and submillimetres. This paper describes the technologies prevailing today for the manufacturing of microactuators. A wealth of examples from the most different application fields clarify their application potential as s...

In den letzten Jahren haben sich die Situation und die Anforderungen in modernen IT Organisationen grundlegend geändert. Zu den drei wichtigsten Aspekten, denen IT Manager heutzutage begegnen müssen, gehören: "Höhere Anforderungen an die Datenverfügbarkeit und Wiederherstellungszeiten nach einem Datenverlust bzw. Systemausfall", "Jährlich stetig steigende Datenvolumina" und "Zunehmender Einsatz...

In many microfluidic MEMS (Micro Electromechanical Systems) especially in μTAS (micro Total Analysis Systems) suspensions of small particles are transported from relatively large chambers into small channels. The sudden contractions at the entrance to these channels are critical flow regions where high shear occurs in the fluid. Even very small particles at low concentrations have been observed...
