Abstract
Although few in number, the various Shiite Muslim communities in Germany are highly diversified in terms of their linguistic, national and ethnic backgrounds and ritual practice. In order to come to terms with these multi-local actors and their specific articulations of Shiism, the article aimes at an analytical framework that integrates an open understanding of belonging: employing Leave and Wenger's concept of "communities of practice", it argues that a focus on common practice in which heterogeneous actors engage, enables us to grasp, on the one hand, the varying specific characteristics of different groups and, on the other, their mutual belonging to the wider Shiite field.

Wie kommt es, dass man noch heute Raubgut der Nationalsozialisten in öffentlichen Einrichtungen wie Bibliotheken findet? Wie konnte es so lange unentdeckt bleiben? Wie wurde es getarnt und wie kann man die verwischten Spuren lesen? Diesen Fragen geht der Autor anhand der Büchersammlung des jüdischen Unternehmerehepaars Edith und Georg Tietz nach. Georg Tietz, Inhaber der Hermann Tietz Warenhäuser (HERTIE), rettete sich und seine Familie nach der ?Arisierung? über Liechtenstein in die USA ins Exil. Dort leben noch heute die Nachfahren. Das Buch erzählt die Geschichte einer einst legendären Privatbibliothek. Es berichtet davon, wie die Sammlung enteignet, verwertet und verborgen wurde. Der Leser erfährt weiterhin, wie die Buchbesitzer 2016 in der Stadtbibliothek Bautzen identifiziert werden konnten und wie die Stadt heute mit der HERTIE-Sammlung umgeht

Accidental battery ingestion in children is a recognized source of significant morbidity and mortality. To mitigate the risks of accidental battery ingestion, legislation has been introduced to regulate the locking of battery compartments. Regulation of battery housings has translated into modest reductions in the number of battery ingestion cases reported. We report here the fabrication of waterproof, pressure-sensitive battery coatings that are nonconductive in the low-pressure gastrointestinal tract, yet conduct in higher-pressure standard battery housings. These safer batteries are expected to reduce complications from accidental battery ingestion.

Hyaluronic acid (HA) has a number of potential biomedical applications in drug delivery and tissue engineering. For these applications, a prerequisite is to understand the characteristic of HA films directly immobilized to solid substrates. Here, we demonstrate that high molecular weight HA can be directly immobilized onto hydrophilic substrates without any chemical manipulation, allowing for the formation of an ultrathin chemisorbed layer. Hyaluronic acid is stabilized on these surfaces through hydrogen bonding between the hydrophilic moieties in HA [such as carboxylic acid (-COOH) or hydroxyl (-OH) groups] with silanol (-SiOH), carboxylic acid or hydroxyl groups on the hydrophilic substrates. Despite the water solubility, the chemisorbed HA layer remained stable on glass or silicon oxide substrates for at least 7 days in phosphate-buffered saline. Furthermore, HA immobilized on silicon and other dioxide surfaces in much higher quantities than other polysaccharides including dextran sulfate, heparin, heparin sulfate, chondroitin sulfate, dermatan sulfate, and alginic acid. This behavior is related to the molecular entanglement and intrinsic stiffness of HA as a result of strong internal and external hydrogen bonding as well as high molecular weight. These results demonstrate that HA can be used to coat surfaces through direct immobilization. ; Dr. Suh thanks the support by the Brain Korea 21 Project in 2004 and Dr. Yang thanks the support from the National Science Council of Republic of China and the partial support from Chang Gung Hospital.

Reliable, real-time heart and respiratory rates are key vital signs used in evaluating the physiological status in many clinical and non-clinical settings. Measuring these vital signs generally requires superficial attachment of physically or logistically obtrusive sensors to subjects that may result in skin irritation or adversely influence subject performance. Given the broad acceptance of ingestible electronics, we developed an approach that enables vital sign monitoring internally from the gastrointestinal tract. Here we report initial proof-of-concept large animal (porcine) experiments and a robust processing algorithm that demonstrates the feasibility of this approach. Implementing vital sign monitoring as a stand-alone technology or in conjunction with other ingestible devices has the capacity to significantly aid telemedicine, optimize performance monitoring of athletes, military service members, and first-responders, as well as provide a facile method for rapid clinical evaluation and triage. ; United States.
