This paper presents a mobile Augmented Reality (AR) system called the SitePack supporting architects in visualizing 3D models in real-time on site. We describe how vision based feature tracking techniques can help architects making decisions on site concerning visual impact assessment. The AR system consists only of a tablet PC, a web cam and a custom software component. No preparation of the s...

Injection s.c. of purine 3-oxide into Wistar rats resulted in the appearance of sarcomas and fibromas at the interscapular site of administration, carcinomas in the liver, and a high incidence of s.c. fibromas in the hip at a distance from the site of injection. A small number of liver tumors but no tumors at the injection site appeared in rats to which the parent compound, purine, was administ...

The Bacillus circulans ATCC 31382 β-galactosidase (BgaD) is a retaining-type glycosidase of glycoside hydrolase family 2 (GH2). Its commercial enzyme preparation, Biolacta N5, is used for commercial-scale production of galacto-oligosaccharides (GOS). The BgaD active site and catalytic amino acid residues have not been studied. Using bioinformatic routines we identified two putative catalytic gl...

UNLABELLED The use of (99m)Tc-sulfur colloid lymphoscintigraphy for the determination of lymph flow patterns from a tumor site and localization of the sentinel node has been widely adopted. However, the effects of multiple injections of the radiopharmaceutical can range from mild discomfort to pain. pH-adjusted lidocaine HCl coadministered with (99m)Tc-sulfur colloid presents a risk of introduc...

We describe how to measure site-specific rates of evolution in protein-coding genes and how to correlate these rates with structural features of the expressed protein, such as relative solvent accessibility, secondary structure, or weighted contact number. We present two alternative approaches to rate calculations, one based on relative amino-acid rates and the other based on site-specific codo...

BACKGROUND Postoperative spinal wound infections are relatively common and are often associated with increased morbidity and poor long-term patient outcomes. The purposes of this study were to identify the common bacterial flora on the skin overlying the lumbar spine and evaluate the efficacy of readily available skin-preparation solutions in the elimination of bacterial pathogens from the surg...

OBJECTIVE We aimed to determine the efficacy and safety of early (within the first 24 hour from application) endoscopy and colonoscopy in very elderly patients with GIS bleeding. METHODS In this study, 95 patients were included who underwent early endoscopy with the pre-diagnosis of upper GIS bleeding or endoscopy-colonoscopy with the pre-diagnosis of lower GIS bleeding between 2012 and 2016....

Focusing on layout and process planning in collaborative environments, the development of infrastructure didactic content for hands-on courses has been progress years at SZTAKI, with inclusion two sites Budapest Győr, respectively. Since 2019, a summer school program preparation involving Pilot Factory Vienna, maintained by Fraunhofer Austria TU Wien. While pandemic forced on-site education to ...
