Politische Bildung in den Lernzentren für Migrantinnen

Das Lernzentrum des Vereins LEFÖ – Beratung, Bildung und Begleitung für Migrantinnen bietet Migrantinnen seit 1989 verschiedene Bildungsangebote und -maßnahmen und unterstützt sie damit in ihren individuellen und unterschiedlichen Lebenssituationen. In den letzten 13 Jahren hat es 12 LEFÖ-Bildungsseminare mit unterschiedlichen Themenschwerpunkten gegeben. Diese Bildungsseminare sind in Österreich die einzige Möglichkeit für eine kontinuierliche und selbstbestimmte Auseinandersetzung mit Migrantinnen und anderen interessierten Frauen aus Österreich, Deutschland und der Schweiz zu Inhalten, die für sie politisch relevant sind. Im Rahmen des Projekts „Lernzentren für Migrantinnen“ wird LEFÖ in Zusammenarbeit mit den Partnerinnenorganisationen peregrina und Orient Express eine Erhebung zu „Politische Bildung in der Migrationsgesellschaft“ durchführen. Es soll dabei ein Umgang mit den den Migrantinnen zugewiesenen sozialen und politischen Positionen gefunden werden. Zentraler Hintergrund bzw. Bestandteil des Arbeitsbereichs sind gesellschaftlich-politische Phänomene und Problematiken wie Rassismus, Interkulturalität, Globalisierung, Gender Mainstreaming, Diversity und Kultur. Der Projektgestaltung wird ein feministisch- und migrationskritischer Ansatz zugrunde liegen. Die Migrantinnen sollen dabei zu Themen zu Wort kommen, zu denen sie sonst kaum gehört oder befragt werden, u.a. zu Geschlecht, zu Demokratisierungsprozessen und zu Bildung. (DIPF/Orig.

Hernia of Morgagni – Case Report

Morgagni’s hernia is result of penetration of the abdominal contents into the chest through an anterior retrocostoxiphoid defect in the anterior midline of the diaphragm. It can be manifested with symptoms since birth as a bloated feeling, nausea and belching after meals. We present a patient with symptomatic herniation of the torqued antral part of stomach and loops of the transverse colon. In our case, chest and abdominal radiography after oral intake of contrast are used to diagnose this condition. Herniation was reduced surgically by a transabdominal approach. At the control examination one year after surgery in our patient all symptoms have disappeared, and was given 15 kg of body weight

A LC-MS-MS method for determination of low doxazosin concentrations in plasma after oral administration to dogs

A rapid and sensitive reversed phase liquid chromatography-tandem mass spectrometry (LC-MS-MS) method is developed for the determination of doxazosin in canine plasma. The samples are prepared by precipitation of proteins using a mixture of methanol and acetonitrile, followed by freezing and evaporation of the organic solvent. The remaining dry residue is redissolved in mobile phase and analyzed by LC-MS-MS with positive electrospray ionization using the selected reactions monitoring mode. An XTerra MS C18 column, a mobile phase composed of acetonitrile and 2mM ammonium acetate with gradient elution, and a flow rate of 400 μL/min are employed. The elution times for prazosin (internal standard) and doxazosin are ~ 8 and 10 min, respectively. Calibration curves are linear in the 1-20 ng/mL concentration range. Limits of detection and quantification are 0.4 ng/mL and 1.2 ng/mL, respectively. Recovery is higher than 94%. Intra- and inter-day relative standard deviations are below 7% and 8%, respectively. The method is applied for the determination of doxazosin plasma levels following a single administration of doxazosin base and doxazosin mesylate tablets (2 mg dose) to dogs in the fed state. The results indicate possible superiority of the mesylate salt on the plasma input rates of doxazosin

Multi-scale undulations in human aortic endothelial cell fibers

Blood vessels often have an undulatory morphology, with excessive bending, kinking, and coiling occuring in diseased vasculature. The underlying physical causes of these morphologies are generally attributed, in combination, to changes in blood pressure, blood flow rate, and cell proliferation or apoptosis. However, pathological vascular morphologies often start during developmental vasculogenesis. At early stages of vasculogenesis, angioblasts (vascular endothelial cells that have not formed a lumen) assemble into primitive vessel-like fibers before blood flow occurs. If loose, fibrous aggregates of endothelial cells can generate multi-cellular undulations through mechanical instabilities, driven by the cytoskeleton, new insight into vasculature morphology may be achieved with simple in vitro models of endothelial cell fibers. Here we study mechanical instabilities in vessel-like structures made from endothelial cells embedded in a collagen matrix. We find that endothelial cell fibers contract radially over time, and undulate at two dominant wavelengths: approximately 1cm and 1mm. Simple mechanical models suggest that the long-wavelength undulation is Euler buckling in rigid confinement, while the short-wavelength buckle may arise from a mismatch between fiber bending energy and matrix deformation. These results suggest a combination of fiber-like geometry, cystoskeletal contractions, and extracellular matrix elasticity may contribute to undulatory blood vessel morphology in the absence of a lumen or blood pressure

Measurement of impact force for triboluminescent-enhanced composites by modified impulse method

Barely visible impact damage in composites can result in hidden damage such as delamination and cracking. Triboluminescence is currently being looked at as a way of inundating composites with a sensory level mechanism for impact events. ZnS:Mn doped resin sensing plates are embedded within glass fiber-reinforced composites and are impacted at low velocities (3.45-3.51 m/s). The damage created by the impact can be seen under black light analysis and allows for quick visual inspection of the composite. The striker during impact registers a bounce which can be used to determine final impact velocity, which in turn defines the force at impact. By measuring the amount of time between consecutive impacts, an indirect estimation of impact force was made using the temporal occurrence of triboluminescence. Triboluminescent emissions occurred for impacts greater than 300 N. The measured impact energy averaged 36.79 J (±0.48). The calculated impact force and impact energy corresponded to the amount of damage area found on the composite, showing that triboluminescent crystal inclusion into composites can provide damage sensing capability to woven fiber composites

Design for additive manufacturing of mechanical connections toward hybrid products

Improving additive manufacturing (AM) products is important since these technologies still have some limitations that restrict production. These limitations are associated with the size of the build envelope, the materials available and the possibility of multi-material fabrication. For this particular case, there are two different strategies: (i) one, is to build fittings that can act as mechanical connections for different parts, or (ii), to embed the parts as external components in the AM build process of the fittings. This paper presents exploratory research to quickly improve AM ceramic products by AM polymeric fittings in the two strategies presented. The overall aim is to describe a methodology that can optimize products using AM material extrusion technology and that can be used for the production of hybrid products.This work has the financial support of the Exploratory Research Project, with the reference MIT-EXPL/ISF/0006/2017, MIT Portugal-2017 Program, financed by National Funds, through FCT/MCTES and by the European Structural and Investment Funds in the FEDER component, through the Operational Competitiveness and Internationalization Programme (COMPETE 2020) [Project nº 002814; Funding Reference: POCI-01-0247-FEDER-002814 and Project nº 002797; Funding Reference: POCI-01-0247-FEDER-002797]
