Malfunctioning areas generate electric cross currents inside bipolar plates. To exploit this we suggest bipolar plates consisting not of two but of three layers. The third one is a highly conducting layer and segmented such that the cross currents move along the segments to the surface of the stack where they can be measured by an inductive sensor. With this information a realistic model can be used to detect the malfunctioning area. Furthermore the third layer will prevent any current inhomogeneity of a malfunctioning cell to spread to neighbouring cells in the stack. In this work the results of measurements in a realistic cell setup will be compared with the results obtained in simulation studies with the same configuration. The basis for the comparison is the reliable characterisation of the electrical properties of the cell components and the implication of these results into the simulation model. The experimental studies will also show the limits in the maximum number of segments, which can be used for a reliable detection of cross currents.

JF - Geophysical Journal International N2 - Following earlier studies, we present forward and inverse simulations of heat and fluid transport of the upper crust using a local 3-D model of the Kola area. We provide best estimates for palaeotemperatures and permeabilities, their errors and their dependencies. Our results allow discriminating between the two mentioned processes to a certain extent, partly resolving the non-uniqueness of the problem. We find clear indications for a significant contribution of advective heat transport, which, in turn, imply only slightly lower ground surface temperatures during the last glacial maximum relative to the present value. These findings are consistent with the general background knowledge of (i) the fracture zones and the corresponding fluid movements in the bedrock and (ii) the glacial history of the Kola area.

Dabei ist vor allem die ganzheitliche Verwertung der Stoffströme von Bedeutung, da diese einen integrativen Ansatz ermöglichen. Im Rahmen dieser Arbeit wird die Produktion von Einzellerproteinen (Single-Cell Proteins, SCPs) mithilfe von unterschiedlichen Rohsubstraten dargelegt. Somit können Reststoffströme, die in keiner Konkurrenz zur Produktion von Lebensmitteln stehen, für die Herstellung von Futter- und auch Nahrungsmitteln Verwendung finden. Die zunächst thermisch vorbehandelten Ausgangsmaterialien stammen aus forstwirtschaftlichen und grünen Abfällen und ermöglichen durch eine anschließende enzymatische Hydrolyse die Freisetzung von Monosacchariden. Aus diesen erfolgt die SCP-Produktion fermentativ mithilfe der drei Modellorganismen Bakterium, Hefe und Pilz. Hierfür wird sowohl das flüssige Hydrolysat als auch der feste Reststoff auf der Basis einer Feststofffermentation genutzt. Auf diese Weise ist eine vollständige Verwertung der Ausgangsmaterialien möglich. Mit den gewonnen Daten erfolgt abschließend eine Bewertung der SCPs aus nachwachsenden Rohstoffen als alternative Proteinquelle.

The current study aims to assess quantitatively vestibular performance before and after exposure to different MRI scenarios at 7 T, 1.5 T and 0 T. Sway path and body axis rotation (Unterberger's stepping test) were quantitatively recorded in a total of 46 volunteers before, 2 minutes after, and 15 minutes after different exposure scenarios: 7 T head MRI (n = 27), 7 T no RF (n = 22), 7 T only B₀ (n = 20), 7 T in & out B₀ (n = 20), 1.5 T no RF (n = 20), 0 T (n = 15). All exposure scenarios lasted 30 minutes except for brief one minute exposure in 7 T in & out B₀. Both measures were documented utilizing a 3D ultrasound system. During sway path evaluation, the experiment was repeated with eyes both open and closed. Sway paths for all long-lasting 7 T scenarios (normal, no RF, only B₀) with eyes closed were significantly prolonged 2 minutes after exiting the scanner, normalizing after 15 minutes. Brief exposure to 7 T B₀ or 30 minutes exposure to 1.5 T or 0 T did not show significant changes. End positions after Unterberger's stepping test were significantly changed counter-clockwise after all 7 T scenarios, including the brief in & out B₀ exposure. Shorter exposure resulted in a smaller alteration angle. In contrast to sway path, reversal of changes in body axis rotation was incomplete after 15 minutes. 1.5 T caused no rotational changes. The results show that exposure to the 7 Tesla static magnetic field causes only a temporary dysfunction or “over-compensation” of the vestibular system not measurable at 1.5 or 0 Tesla. Radiofrequency fields, gradient switching, and orthostatic dysregulation do not seem to play a role.
