Comparison of methods for broadband electromagnetic characterization of Molded Interconnect Device materials
Combining the Molded Interconnect Device technology with the Laser Direct Structuring technology exhibits the potential of designing electrical and mechanical components on three-dimensional surfaces to increase functionality, level of integration and to reduce costs. When taking advantage of this technology especially in the design of RF devices, a precise knowledge of the electromagnetic parameters of the MID material is required, as the complex permeability and permittivity strongly influence the device performance. At present time, these materials are not electromagnetically characterized in the RF frequency range. In this paper different methods are therefore presented and compared with respect to their potentials for broadband electromagnetic characterization of Molded Interconnect Device materials
Specific bottom–up effects of arbuscular mycorrhizal fungi across a plant–herbivore–parasitoid system
The majority of plants are involved in symbioses with arbuscular mycorrhizal fungi (AMF), and these associations are known to have a strong influence on the performance of both plants and insect herbivores. Little is known about the impact of AMF on complex trophic chains, although such effects are conceivable. In a greenhouse study we examined the effects of two AMF species, Glomus intraradices and G. mosseae on trophic interactions between the grass Phleum pratense, the aphid Rhopalosiphum padi, and the parasitic wasp Aphidius rhopalosiphi. Inoculation with AMF in our study system generally enhanced plant biomass (+5.2%) and decreased aphid population growth (−47%), but there were no fungal species-specific effects. When plants were infested with G. intraradices, the rate of parasitism in aphids increased by 140% relative to the G. mosseae and control treatment. When plants were associated with AMF, the developmental time of the parasitoids decreased by 4.3% and weight at eclosion increased by 23.8%. There were no clear effects of AMF on the concentration of nitrogen and phosphorus in plant foliage. Our study demonstrates that the effects of AMF go beyond a simple amelioration of the plants’ nutritional status and involve rather more complex species-specific cascading effects of AMF in the food chain that have a strong impact not only on the performance of plants but also on higher trophic levels, such as herbivores and parasitoids

ThielViewer - an interactive visualization tool for: Do emergency ventilators deliver preset tidal volumes? - Mechanical ventilation in a human cadaver model of asynchronous cardiopulmonary resuscitation.
This repository contains a compiled software tool to process and review respiratory data from CSV files on Windows operating systems. It was written for a raw dataset [1] obtained in a study of simulated CPR in Thiel-embalmed cadavers [research paper - coming soon].
The tool visualizes measured flow, airway pressure and esophageal pressure. Additionally, it derives and plots volumes, as well as transpulmonary pressure, as described in the accompanying data publication [data publication - coming soon]. To improve orientation, the program can highlight segments of the study protocol within the tracings.
The plots are fully interactive, can be rescaled, zoomed in, and panned back and forth

Data for: Do emergency ventilators deliver preset tidal volumes? - Mechanical ventilation in a human cadaver model of asynchronous cardiopulmonary resuscitation.
We conducted a crossover study of different ventilators in a human cadaver model of asynchronous cardiopulmonary resuscitation, to investigate wether transport respirators are able to provide ventilation during ongoing chest compressions [research paper - coming soon]. We found ventilations to be highly fragmented by chest compressions with meaningful reduction of deliverd tidal volumes. We also found significant differences of tidal volume reduction between the evaluated ventilators.The repository contains raw data recordings of flow, airway pressure, esophageal pressure, depth of the automated chest compression piston, and force of the automated chest compression piston. The dataset of derived values and especially volumes analysed is included in this repository.Data of this repository is described in detail in a co-submitted data publication [data publication - coming soon].This data enables readers to review tracings of all respiratory measurements on raw data level. In another repository we provide a plotting tool to do so [3]. The data may be used to examine interactions of chest compressions and ventilations during cardiopulmonary resuscitation in depth.THIS DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Heute die Möglichkeiten schaffen, um morgen die richtigen Antworten zu bekommen: Anmerkungen zum MIND3
With the implementation of the updated minimum emergency data set MIND3 in 2011, the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) created a simplified and therefore more powerful tool for supraregional acquisition of prehospital emergency medical data and quality management. While discussing the adaptation, the working group of the Austrian Society for Anesthesiology, Resuscitation and Intensive Care Medicine (ÖGARI) raised the question for further usability of the data set, e.g. linkage to other health records or use for scientific purposes. Most important to achieve this goal is the possibility of data association and matching data sets. Data privacy protection laws prohibit use of individual patient data for register purposes. Although being a good tool for overall quality management, MIND3 especially fails in questions where it is crucial to handle an individual as a consistent entity without disclosing personally identifiable information. Future application spectrum seems to be limited. To facilitate higher performance, it is urgently necessary to define the further purposes of patient data recording and to develop safe technological solutions. Possible implementations on privacy protection politics have to be identified and discussed
