Background To improve patient safety, training of psychomotor laparoscopic skills is often done on virtual reality (VR) simulators outside the operating room. Haptic sensations have been found to influence psychomotor performance in laparoscopy. The emulation of haptic feedback is thus an...

The die shear strength has been studied as a function of bond frame geometry for wafer-level Au-Au thermo-compression bonds. The shear strength of samples with a 100 and 200 μm wide bond frame (bond area 1 – 2 mm2) was higher and more uniform than that of samples with a 400 μm wide bond frame (bond...

Single-crystalline sodium tungsten bronze (Na-WO3) nanorods with typical diameters of 10–200 nm and lengths of several micrometers were prepared via hydrothermal synthesis. The as-prepared Na-WO3 nanorods crystallized in a hexagonal structure (space group P6/mmm) with unit cell parameters a...

This paper studies dynamic behaviour and control design of a hydrogen membrane reforming (HMR) power cycle based on economic measures. The HMR power cycle is a novel pre-combustion capture power cycle for electrical power production which incurs less of an energy penalty than current post combustion...

Lightweight aggregates (LWAs) were successfully produced both in a pilot-scale rotary kiln and in a laboratory chamber furnace. The mechanical properties of LWA were investigated in detail applying the European standard crushing resistance test (CR-test) as well as the single pellet compression test...

Aims: To investigate the associations between work environment indicators and health- related work disability. Methods: A health survey of 5,749 working 40–42-year-old Norwegians from Nordland County were linked to a national register for disability pension during a follow-up of over 18 years. The...
