Robotic Sensing and Stimuli Provision for Guided Plant Growth Mostafa Wahby1, Mary Katherine Heinrich1,5, Daniel Nicolas Hofstadler2, Julian Petzold1, Igor Kuksin3, Payam Zahadat2,4, Thomas Schmickl2, Phil Ayres5, Heiko Hamann1 1Institute of Computer Engineering, University of Lübeck, 2Institute of Biology, Artificial Life Lab, University of Graz, 3Cybertronica UG, 4Department of Computer Science, IT University of Copenhagen, 5Centre for IT and Architecture, Royal Danish Academy Distributed robot nodes provide sequences of blue light stimuli to steer the growth trajectories of climbing plants. By activating natural phototropism, the robots guide the plants through binary left-right decisions, growing them into predefined patterns that by contrast are not possible when the robots are dormant.
Oral Biofilm Analysis of Palatal Expanders by Fluorescence In-Situ Hybridization and Confocal Laser Scanning Microscopy Barbara Klug1,2, Claudia Rodler1, Martin Koller3, Gernot Wimmer3, Harald H. Kessler2, Martin Grube4, Elisabeth Santigli1 1Department of Orthodontics and Maxillofacial Orthopedics, Medical University of Graz, 2Institute of Hygiene, Microbiology and Environmental Medicine, Medical University of Graz, 3Department of Prosthodontics, Restorative Dentistry, Periodontology and Implantology, Medical University of Graz, 4Institute of Plant Sciences, Karl-Franzens-University Graz We present a protocol for structural and compositional analysis of natural oral biofilm from orthodontic appliances with in situ hybridization (FISH) and confocal laser scanning microscopy (CLSM). Oral biofilm samples were collected from palatal expanders, scraping acrylic-resin flakes off their surface and referring them for molecular processing.
Microwave Assisted Rapid Diagnosis of Plant Virus Diseases by Transmission Electron Microscopy Bernd Zechmann1,2, Gerhard Graggaber1, Günther Zellnig1 1Institute of Plant Sciences, University of Graz, 2Institute for Electron Microscopy and Fine Structure Research, Graz University of Technology This study describes a method that allows the rapid and clear diagnosis of plant virus diseases in about half a day by using a combination of microwave assisted plant sample preparation for transmission electron microscopy and negative staining methods.
