At the University of Applied Sciences Mainz, Prof. Michael Orthwein initiated in 2008, a consecutive sequence of courses under the common name: "Beyond the Screen" which are being offered within the Time-Based Media degree program. In this series of project-based courses new strategies and new approaches towards visualisation of content are being developed aiming at experimental and applied vis...

BACKGROUND With the introduction of an add-on handcycle, a crank system that can be placed in front of a wheelchair, handcycling was made widely available for daily life. With it, people go into town more easily, e.g. to do groceries; meet up with friends, etc. They have more independency and can be socially active. Our aim is to explore some settings of the handcycle, so that it can be optimal...

PURPOSE Synthesis of star-shaped block copolymer with oxalyl chloride and preparation of micelles to assess the prospect for drug-carrier applications. MATERIALS AND METHODS Three-arm star block copolymers of poly(lactic-co-glycolic acid) (3S-PLGA)-polyethylene glycol (PEG) were synthesized by ring-opening polymerization, then PEG as the hydrophilic block was linked to the terminal hydroxyl o...

The low-RPM Torque Converter (LRTC) is a rotating generator concept for use on the seabed with driving force from sea waves motion surface. This built up of two identical generators connected opposite each other via spring drum built-in ball bearing clutch. to buoy surface wire, wire rolled around drum. With waves, moves either upwards or downwards and pulls downwards. movement causes spin.&#x0...

BACKGROUND/AIMS Microgravity (µg) has adverse effects on the eye of humans in space. The risk of visual impairment is therefore one of the leading health concerns for NASA. The impact of µg on human adult retinal epithelium (ARPE-19) cells is unknown. METHODS In this study we investigated the influence of simulated µg (s-µg; 5 and 10 days (d)), using a Random Positioning Machine (RPM), on ARP...

background: aim of this study is to evaluate the accuracy of the gated volumetric modulated arc therapy (vmat/rapidarc) using 2d planar dosimetry, dynalog files and compass 3d dosimetry system. materials and methods: pre-treatment quality assurance of 10 gated vmat plans was verified using 2d array and compass 3d dosimetry system. advantage of compass over 2d planar is that it provides the clin...

Microprocessor-Based Closed-Loop Motor Control A dedi~ated microprocessor control system was built from chip level using the Motorola M6800 family. The system has a keyboard and the interfaces for four LED displays, a phototransistor and a digital-to-analog converter. The system was designed to execute a closed loop motor control. The system accepts key input in RPM and drives the motor at the ...
