Democracy barometer: a new approach to evaluating the quality of democratic systems

How do we assess the quality of democracy in democratic systems? Like Democratic Audit UK, the Democracy Barometer team are interested in going beyond the headline fact of whether systems are democratic or not, and assessing the subtle differences that affect the quality of democracy from a citizen perspective. Here, Marc Bühlmann, Lea Heyne, Wolfgang Merkel, Lisa Müller, Saskia Ruth and Bernhard Weßels discuss the Democracy Barometer project and how it works

Evaluar la alternativa de disposición del papel higiénico al sistema de drenaje hidrosanitario

Trabajo de Investigación TecnológicaEl proyecto consistió en evaluar una alternativa experimental con el papel higiénico cuando es depositado en la red de drenaje hidrosanitario, para esto se diseñó un prototipo de aparato sanitario que simulara el proceso de descarga de un sanitario, con el fin de evaluar si luego de la descarga con el papel higiénico se afectan las funciones hidráulicas del sistema.RESUMEN INTRODUCCIÓN 1.

Rationale and design of the RIACT–study: a multi-center placebo controlled double blind study to test the efficacy of RItuximab in Acute Cellular tubulointerstitial rejection with B-cell infiltrates in renal Transplant patients: study protocol for a randomized controlled trial

BACKGROUND: Acute kidney allograft rejection is a major cause for declining graft function and has a negative impact on the long-term graft survival. The majority (90%) of acute rejections are T-cell mediated and, therefore, the anti-rejection therapy targets T-cell-mediated mechanisms of the rejection process. However, there is increasing evidence that intragraft B-cells are also important in the T-cell-mediated rejections. First, a significant proportion of patients with acute T-cell-mediated rejection have B-cells present in the infiltrates. Second, the outcome of these patients is inferior, which has been related to an inferior response to the conventional anti-rejection therapy. Third, treatment of these patients with an anti-CD20 antibody (rituximab) improves the allograft outcome as reported in single case observations and in one small study. Despite the promise of these observations, solid evidence is required before incorporating this treatment option into a general treatment recommendation. METHODS/DESIGN: The RIACT study is designed as a randomized, double-blind, placebo-controlled, parallel group multicenter Phase III study. The study examines whether rituximab, in addition to the standard treatment with steroid-boli, leads to an improved one-year kidney allograft function, compared to the standard treatment alone in patients with acute T-cell mediated tubulointerstitial rejection and significant B-cell infiltrates in their biopsies. A total of 180 patients will be recruited. DISCUSSION: It is important to clarify the relevance of anti-B cell targeting in T-cell mediated rejection and answer the question whether this novel concept should be incorporated in the conventional anti-rejection therapy.

Jovanka kommt an! Stadtgestaltung für einen inklusiven Campus Lichtwiese. Städtebaulicher Entwurf im Sommersemester 2017.

Der TU Darmstadt Campus Lichtwiese wird sich in den nächsten Jahrzehnten stark entwickeln. Zur Debatte stehen eines neues Mobilitätskonzept, die Neuordnung der Freiflächen und Nachverdichtung durch studentisches Wohnen. In Rahmen des Entwurfs sollen in Zusammenarbeit mit Studierenden mit eingeschränkter Mobilität, Seh- oder Höreinschränkung, und Newcomern in Darmstadt Konzepte entwickelt werden, die Zugänglichkeit und Aufenthaltsqualität des Campus (für eine der Gruppen) im Sinne des Universal Design und des Access for All erhöhen

Characterisation of Elastomers as Food Contact Materials–Part 1: Quantification of Extractable Compounds, Swelling of Elastomers in Food Simulants and Release of Elements

Elastomers are not a uniform class of materials but comprise a broad spectrum of chemically different polymers. Sealing gaskets, gloves, teats, conveyor belts and tubing are examples of elastomers being used as food contact materials (FCMs). Ten elastomer samples were evaluated with respect to the content of extractable compounds, migration of substances into ethanolic food simulants, swelling in food simulants and release of elements in different food simulants. The number of extractable substances <1000 Da was determined by comprehensive two-dimensional gas chromatography coupled with flame ionisation detection (GC × GC–FID) analysis of tetrahydrofuran (THF) extracts. The number of signals ranged from 61 (a thermoplastic elastomer (TPE)) to 690 (a natural rubber/styrene-butadiene-rubber blend (NR/SBR)). As for risk assessment, the decisive factor is which substances reach the food. The extent of substances that migrate into ethanolic food simulants was investigated. Elastomer FCMs can be the source of food contamination with heavy metals. Notably, contamination with lead was detected in some samples investigated in this study. It was shown that food simulants harbour the potential to morphologically alter or even disintegrate elastomeric materials. The results presented here highlight the importance to carefully choose the elastomer type for the intended use as FCMs as not every application may prove safe for consumers

Neuroethik - Geschichte, Definition und Gegenstandsbereich eines neuen Wissenschaftsgebiets

Definition of the problem: Fifteen years after establishing neuroethics as an international academic field, neuroethics has emerged as a vibrant, dynamic area of scientific research. Arguments: Within a short period of a few years, specific conferences, journals, research funding programs, professional societies, and institutes were founded. Nonetheless, considerable disagreement about its definition and subject matter still remain. We argue for a differentiated conceptualization according to which the deliberate reflection of ethical problems arising from the neurosciences and their predominantly neurotechnological application belongs as much to neuroethics as does the ethical reflection of the neuroscience of morality. This does not comprise neuroscientific or neuropsychological research on morality itself, but includes the contemplation of the significance of such research for ethics and the law. Here, we provide an overview about the most important topics in neuroethics and elucidate the relevance of neuroethics for a vast diversity of societal domains reaching well beyond medicine and health care. Conclusion: The great potential of neuroethics as a novel branch of academic research lies in finding new answers to pressing questions of high societal relevance by linking neurophilosophy and bioethics topics as well as its broad interdisciplinary network
