Über die Nutzung des Angebots der Behindertenbeauftragten der Universität Wien von Studierenden mit Mobilitätsbeeinträchtigungen

Die Angebote der Behindertenbeauftragten der Universität Wien werden derzeit nur von einem Bruchteil der Studierenden mit Beeinträchtigungen genutzt. In dieser Arbeit wurde den Gründen dafür nachgegangen, wobei der Fokus auf Studentinnen und Studenten mit Mobilitätsbeeinträchtigungen gelegt wurde. Während der erste Teil dieser Diplomarbeit einen kurzen, theoretischen Hintergrund zu dem Thema (Hochschul-) Bildung von Menschen mit Beeinträchtigungen liefert, wird im zweiten Teil auf die empirische Untersuchung eingegangen, bei der, neben den Motiven für die (mangelnde) Nutzung der Beratungsstelle, auch Erkenntnisse über die Zufriedenheit der StudentInnen mit dem Angebot, sowie über mögliche Verbesserungswünsche, gewonnen werden konnten.Actually only a fraction of the students with impairments uses the services of the commissioner for people with disabilities of the University of Vienna. By focusing on students with mobility impairments, this thesis investigates the reasons for this striking fact. The first part of this diploma thesis presents a short, theoretical background to (university-) education of people with impairments. The second part deals with the empirical research, which did not only reveal the reasons of the students for using or not using the counseling office, but also brought about findings on their contentment with the offer as well as suggestions for improvement

A SECOND CHANCE FOR ENTREPRENEURS IN THE REPUBLIC OF MOLDOVA: CHALLENGES AND SOLUTIONS

The relevance of offering a second chance is determined not only by the need to mitigate the consequences of business failure and motivate the entrepreneur to continue his entrepreneurial activity, but also by the impact on the country’s economy, as business closure leads to job losses, a worsening of the financial possibilities of the national and local budgets, reduction of competition and other negative trends in the internal market. The importance of these issues has increased significantly in the context of the COVID-19 pandemic, leading to significant deterioration of the Moldovan business environment. The aim of the paper is to identify the barriers and needs of entrepreneurs, who face financial or other difficulties, are in a state of insolvency, have gone through restructuring/bankruptcy proceedings and would like to benefit from a second chance in Moldova. The research methodology is based on the analysis of legislative acts in the field; statistical data analysis; the results of 16 semi-structured interviews with entrepreneurs on elucidating the factors that favor and hinder the entrepreneurial activity, related to obtaining a second chance in business. The interviews were conducted between April and August 2018. The research results showed that both internal factors (insufficient financial resources, knowledge of crisis management, mismanagement, insufficient staff qualification, including the entrepreneurial skills / experience of the owners, the lack of people with certain professions) and external (related to insolvency legislation, limited information on the possibilities that can be used in case of failure) are determining for taking a second chance

Case series of volar juvenile xanthogranuloma: Clinical observation of a peripheral rim of hyperkeratosis

Juvenile xanthogranuloma is a benign histiocytic tumor predominantly occurring in children as yellowish papules on the head and trunk. Presentations on the volar surfaces are rare and may cause diagnostic confusion with pyogenic granuloma, eccrine poroma and digital fibrokeratoma. We report two patients with unusual presentations of solitary juvenile xanthogranuloma on the palm or sole. Both had lesions lacking the classic yellowish color and demonstrating a well‐defined, peripheral hyperkeratotic rim. Histopathological evaluation revealed prominent orthokeratosis corresponding to the rim. Additional histological features, including dermal histiocytes and Touton giant cells, were consistent with the diagnosis of juvenile xanthogranuloma. Given the unusual locations and colors of the lesions, we conclude that histopathological evaluation is central to diagnosing volar juvenile xanthogranuloma. We additionally suggest that juvenile xanthogranuloma should be included in the differential diagnoses of volar lesions displaying a peripheral hyperkeratotic rim.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/108660/1/jde12617.pd

Magnetic hybrid Pd/Fe-oxide nanoparticles meet the demands for ablative thermo-brachytherapy

Objective: To investigate the potential of hybrid Pd/Fe-oxide magnetic nanoparticles designed for thermo-brachytherapy of breast cancer, considering their specific loss power (SLP) and clinical constraints in the applied magnetic field. Methods: Hybrid nanoparticles consisting of palladium-core and iron oxide shell of increasing thickness, were suspended in water and their SLPs were measured at varying magnetic fields (12–26 mT peak) and frequencies (50–730 kHz) with a commercial alternating magnetic field generator (magneTherm™ Digital, nanoTherics Ltd.). Results: Validation of the heating device used in this study with commercial HyperMag-C nanoparticles showed a small deviation (±4%) over a period of 1 year, confirming the reliability of the method. The integration of dual thermometers, one in the center and one at the bottom of the sample vial, allowed monitoring of homogeneity of the sample suspensions. SLPs measurements on a series of nanoparticles of increasing sizes showed the highest heating for the diameter of 21 nm (SLP = 225 W/g) at the applied frequencies of 346 and 730 kHz. No heating was observed for the nanoparticles with the size &lt;14 nm, confirming the importance of the size-parameter. The heating ability of the best performing Pd/Fe-oxide-21 was calculated to be sufficient to ablate tumors with a radius ±4 and 12 mm using 10 and 1 mg/mL nanoparticle concentration, respectively. Conclusions: Nanoparticles consisting of non-magnetic palladium-core and magnetic iron oxide shell are suitable for magnetic hyperthermia/thermal ablation under clinically safe conditions of 346 kHz and 19.1 mT, with minimal eddy current effects in combination with maximum SLP.</p

Colon Ascendens Stent Peritonitis (CASP) - a Standardized Model for Polymicrobial Abdominal Sepsis

Sepsis remains a persistent problem on intensive care units all over the world. Understanding the complex mechanisms of sepsis is the precondition for establishing new therapeutic approaches in this field. Therefore, animal models are required that are able to closely mimic the human disease and also sufficiently deal with scientific questions. The Colon Ascendens Stent Peritonitis (CASP) is a highly standardized model for polymicrobial abdominal sepsis in rodents. In this model, a small stent is surgically inserted into the ascending colon of mice or rats leading to a continuous leakage of intestinal bacteria into the peritoneal cavity. The procedure results in peritonitis, systemic bacteraemia, organ infection by gut bacteria, and systemic but also local release of several pro- and anti-inflammatory cytokines. The lethality of CASP can be controlled by the diameter of the inserted stent. A variant of this model, the so-called CASP with intervention (CASPI), raises opportunity to remove the septic focus by a second operation according to common procedures in clinical practice. CASP is an easily learnable and highly reproducible model that closely mimics the clinical course of abdominal sepsis. It leads way to study on questions in several scientific fields e.g. immunology, infectiology, or surgery

Transgenic Introduction of a Glycolate Oxidative Cycle into A. thaliana Chloroplasts Leads to Growth Improvement

The photorespiratory pathway helps illuminated C3-plants under conditions of limited CO2 availability by effectively exporting reducing equivalents in form of glycolate out of the chloroplast and regenerating glycerate-3-P as substrate for RubisCO. On the other hand, this pathway is considered as probably futile because previously assimilated CO2 is released in mitochondria. Consequently, a lot of effort has been made to reduce this CO2 loss either by reducing fluxes via engineering RubisCO or circumventing mitochondrial CO2 release by the introduction of new enzyme activities. Here we present an approach following the latter route, introducing a complete glycolate catabolic cycle in chloroplasts of Arabidopsis thaliana comprising glycolate oxidase (GO), malate synthase (MS), and catalase (CAT). Results from plants bearing both GO and MS activities have already been reported (Fahnenstich et al., 2008). This previous work showed that the H2O2 produced by GO had strongly negative effects. These effects can be prevented by introducing a plastidial catalase activity, as reported here. Transgenic lines bearing all three transgenic enzyme activities were identified and some with higher CAT activity showed higher dry weight, higher photosynthetic rates, and changes in glycine/serine ratio compared to the wild type. This indicates that the fine-tuning of transgenic enzyme activities in the chloroplasts seems crucial and strongly suggests that the approach is valid and that it is possible to improve the growth of A. thaliana by introducing a synthetic glycolate oxidative cycle into chloroplasts
