This paper presents the design and implementation of a system applicable for autonomous repair welding on huge forming tools, often realized as blacksmith’s swages. The automated repair welding process restores the tool with its desired shape independent to the tools actual state of abrasion. The core of the system is provided by a computer connected to sensors and an eight axis welding robot. ...

Filming is an analogue process; it requires a mechanical process to record and view, and the source material itself is prone to decay & abrasion [1]. Film is expensive to store, and prohibitively expensive to restore. It is important to note that these problems do not just affect ‘old’ movies; aside from the minority of films that have made use of digital cinema cameras, all previous & most cur...

CLINICAL QUESTION What is the best treatment for traumatic corneal abrasion? RESULTS Eye patching does not reduce pain in patients with corneal abrasions. Topical diclofenac does reduce pain in patients with corneal abrasions IMPLEMENTATION Pitfalls to avoid when treating abrasions: Treatment of small abrasions Treatment of larger abrasions When to refer for specialist treatment.

Context: Nanocomposites are becoming popular today because of the manufacturers claiming high surface smoothness and good abrasion resistance properties thus improving the longevity of the restoration. Aims: This in vitro study was carried out to investigate the effect of nanofillers on surface roughness and abrasion resistance of nanofilled compositeFiltek Z350 (3M ESPE) and nanohybrid composi...

PURPOSE This study was conducted to evaluate the effects of different phosphate monomer-containing primers on the shear bond strength between yttria-tetragonal zirconia polycrystal (Y-TZP) ceramics and MDP-containing self-adhesive resin cement. MATERIALS AND METHODS Y-TZP ceramic surfaces were ground flat with #600-grit SiC paper and divided into six groups (n = 10). They were treated as foll...

Abrasion dusts from three types of commercially available non-steel brake pads were generated by a brake dynamometer at disk temperatures of 200, 300 and 400 1C. The number concentration of the abrasion dusts and their aerodynamic diameters (Dp) were measured by using an aerodynamic particle sizer (APS) spectrometer with high temporal and size resolution. Simultaneously, the abrasion dusts were...
