Abstract

Background: The 2002 Medical Licensure Act gave German universities certain freedoms for reforming their medical degree courses. The Medical Faculty of the University of Cologne took advantage of this opportunity and introduced a model study course in the winter semester 2003/04 through §41 of the Medical Licensure Act. One of the main reasons for this was that back then there was an increasing shortage of doctors in clinical curative medicine and GP primary care. This study investigates whether the introduction of the Cologne Model Study Course (MSG) can show stronger interest in curative medical work (especially General Practice) compared to students of the standard degree course (RSG).Methodology: The proof of added value was examined through graduate surveys conducted at the University of Cologne and through the proportion of students who completed the PY elective rotation “General Practice”. The students of the standard degree course (start of studies prior to winter semester 2003/2004) were compared with students of the model study course (start of studies from winter semester 2003/04 onwards). Measurements were carried out using descriptive frequency tables and correlation analyzes according to Spearman.Results: The students’ interest in curative medicine was already high (91%) even before the model study course was introduced and increased only slightly (to 91.9%). There is also only a slight increase in specialization in General Practice (RSG=5.9% vs. MSG=9.2%). However, selection of rotations in General Practice was significantly increased (RSG=1.9% vs. MSG=3.4%, r=0.046 **, p

Abstract

The presence of security vulnerabilities in automotive networks has already been shown by various publications in recent years. Due to the specification of the Controller Area Network (CAN) as a broadcast medium without security mechanisms, attackers are able to read transmitted messages without being noticed and to inject malicious messages. In order to detect potential attackers within a network or software system as early as possible, Intrusion Detection Systems (IDSs) are prevalent. Many approaches for vehicles are based on techniques which are able to detect deviations from specified CAN network behaviour regarding protocol or payload properties. However, it is challenging to detect attackers who secretly connect to CAN networks and do not actively participate in bus traffic. In this paper, we present an approach that is capable of successfully detecting unknown CAN devices and determining the distance (cable length) between the attacker device and our sensing unit based on Time Domain Reflectometry (TDR) technique. We evaluated our approach on a real vehicle network., Comment: Submitted to conference

Abstract

Besides size and polymorphic form, crystal shape takes a central role in engineering advanced solid materials for pharmaceutical and chemical industry. This work demonstrates how multiple cycles of growth and dissolution can manipulate the habit of an acetylsalicylic acid crystal population. Considerable changes of the crystal habit could be achieved within minutes due to rapid cycling, i.e., up to 25 cycles within

23. Continuous Crystallization of Proteins in a Tubular Plug-Flow Crystallizer

Abstract

Protein crystals have many important applications in many fields, including pharmaceutics. Being more stable than other formulations, and having a high degree of purity and bioavailability, they are especially promising in the area of drug delivery. In this contribution, the development of a continuously operated tubular crystallizer for the production of protein crystals has been described. Using the model enzyme lysozyme, we successfully generated product particles ranging between 15 and 40 μm in size. At the reactor inlet, a protein solution was mixed with a crystallization agent solution to create high supersaturations required for nucleation. Along the tube, supersaturation was controlled using water baths that divided the crystallizer into a nucleation zone and a growth zone. Low flow rates minimized the effect of shear forces that may impede crystal growth. Simultaneously, a slug flow was implemented to ensure crystal transport through the reactor and to reduce the residence time distribution., A tubular crystallizer for the continuous production of lysozyme crystals was developed. Control of supersaturation along the tube was achieved by using water baths of various temperatures. By using the suggested settings, protein crystals in the size range of 15−40 μm were produced with residence times of less than 2 h.

Abstract

Surface or shape reconstruction from 3D digitizations, range pictures play an important role as the sizes and accessibility of the sampled object become intractable -- Range pictures, however, present challenges regarding: (i) recovery of topological structure from geometrical information of a partial view: (ii) inclusion of several or self obstructing objects on the same picture, and (iii) conciliation of partial topological and geometrical information from the individual views into a main model -- Issue (i) and (ii) require introduction of data structures and algorithms able to consistently represent incompleteness and discontinuities in the surface -- Aspect (iii) demands the application of statistical methods to sort redundant e inconsistent information in the overlaps between the individual views -- In this investigation, tasks (i) and (ii) have been undertaken by designing and populating an extended Boundary Representation (B-rep), using equivalence relations that induce partitions on the data sets -- Task (iii) has been carried out by using data processing tools (DigitLAB) that filter, resample, and recover shape from planar digitizations, by applying formalisms of differential topology

Abstract

How to motivate and enthuse medical students for science is a longstanding question in medical education. That physicians need not only a solid foundation in critical thinking skills but also need to understand how science is made is self-evident since Abraham Flexner’s famous report in 1910.[for full text, please go to the a.m. URL], Jahrestagung der Gesellschaft für Medizinische Ausbildung (GMA)
