Amylopectin: a major component of the residual body inCryptosporidium parvumoocysts
2004
Amylopectin is used for carbohydrate storage in different life-stages of a number of apicomplexan parasites. We have performed an ultrastructural analysis of amylopectin granules from the oocyst residual body and sporozoites ofCryptosporidium parvum. Amylopectin granules were studiedin situand after isolation from ‘French’ press disrupted parasites, by conventional transmission electron microscopy (TEM) of sectioned oocysts and various negative staining and cryoelectron microscopy techniques. Within the membrane-enclosed oocyst residuum large amylopectin granules (0·1–0·3 μm) can be found besides a characteristic large lipid body and a crystalline protein inclusion. Smaller granules were de…
Modeling of the process of moisture loss during the storage of dried apricots
2011
[EN] Moisture content is a reference parameter for dried food because the growth of most microorganisms is inhibited below certain water activity levels. In addition, it has a determining influence on the evolution of important parameters, such as color and flavor, and on other properties and deterioration reactions, such as texture, oxidation processes and nutritional value. During the storage of some dried fruits, moisture is produced due to Maillard reactions and exchanged with the surrounding environment through the packaging. The evolution of dried foods during their shelf life depends on the storage conditions. The aim of this study is to analyze the evolution of the moisture content …
GRID STABILITY IMPROVEMENT BY RES-BASED GENERATORS AND BATTERY ENERGY STORAGE SYSTEMS IN SMALL ISLANDS
2021
The integration of Renewable Energy Sources (RES) with power electronics interface to the grid, without the back-up of rotating inertia, endangers frequency stability. This issue becomes particularly critical in isolated power systems, like those of small islands not supplied by the main grid, in the case of high shares of production from unpredictable renewables such as photovoltaic and wind sources. Consequently, to preserve the security and the reliability of these systems, it is necessary to adopt new frequency adjustments mechanisms. In this context, the thesis investigates the transition toward an economically and technically feasible generating system based on RES, to achieve specifi…
Hornhaut-Schlüsselbefunde im Kindesalter als Hinweis für therapierbare systemische Stoffwechselerkrankungen
2013
Es gibt eine Reihe von systemischen lysosomalen Stoffwechselerkrankungen, bei denen bereits im Kindesalter krankheitsspezifische Hornhauttrubungen zu beobachten sind. Unter Lysosomen verstehen wir winzige Zellorganellen, die vom Golgi-Apparat gebildet werden. Sie enthalten verschiedene hydrolytische Enzyme und Phosphatasen, womit Fremdstoffe oder korpereigene Stoffe verdaut werden konnen. Die richtige Einordnung der Hornhautveranderung durch den Augenarzt an der Spaltlampe kann zur richtigen Diagnose der jeweiligen systemischen Stoffwechselerkrankung fuhren. Eine moglichst fruhe Diagnosestellung ist aktuell besonders bedeutend, da heute einem Grosteil der Patienten mit einer Speicherkrankhe…
Pränatale Diagnostik der Sialidose, eines Defektes des lysosomalen Enzyms Neuraminidase
1988
Die Sialidose, eine lysosomale Speicherkrankheit aus der Gruppe der Oligosaccharidosen, ist ein genetischer Enzymdefekt mit stark eingeschrankter Lebenserwartung des betroffenen Kindes. Nach vorheriger Geburt eines an dieser Erkrankung verstorbenen Kindes gelang mit Hilfe der biochemischen Analyse von Amnionzellen der korrekte pranatale Ausschlus einer Sialidose unter Voraussage eines heterozygoten Ubertragerstatus. Aus nicht geklarter Ursache war das Wachstum sowohl der Amnionzellen als auch der postnatal untersuchten Fibroblasten deutlich vermindert. Diese Beobachtung sollte bei weiteren pranatalen Untersuchungen uberpruft werden. Die Moglichkeit der pranatalen Diagnostik einer Sialidose …
H$^{-}$ extraction systems for CERN’s Linac4 H$^{-}$ ion source
2018
Linac4 is a 160 MeV linear H accelerator at CERN. It is an essential part of the beam luminosity upgrade of the Large Hadron Collider (LHC) and will be the primary injector into the chain of circular accelerators. It aims at increasing the beam brightness by a factor of 2, when compared to the currently used 50 MeV linear proton accelerator, Linac2. Linac4’s ion source is a cesiated RF-plasma H ion source. Several beam extraction systems were designed for H beams of 45 keV energy, 50 mA intensity and an electron to H ratio smaller than 5. The goal was to extract a beam with an rms-emittance of mm mrad. One of the main challenges in designing an H extraction system is dumping of the co-extra…
Physics beyond colliders at CERN: beyond the Standard Model working group report
2019
The Physics Beyond Colliders initiative is an exploratory study aimed at exploiting the full scientific potential of the CERN's accelerator complex and scientific infrastructures through projects complementary to the LHC and other possible future colliders. These projects will target fundamental physics questions in modern particle physics. This document presents the status of the proposals presented in the framework of the Beyond Standard Model physics working group, and explore their physics reach and the impact that CERN could have in the next 10–20 years on the international landscape.

Synthesis of fluorinated oxadiazoles with gelation and oxygen storage ability
2012
A new family of fluorinated low molecular weight (LMW) gelators has been synthesized through SNAr substitution of 5-polyfluoroaryl-3-perfluoroheptyl-1,2,4-oxadiazoles with glycine ester. The obtained compounds give thermal and pH-sensitive hydrogels or thermo-reversible organogels in DMSO. Oxygen solubility studies showed the ability to maintain high oxygen levels in solution and in gel blend with plate counter agar (PCA).
Optimization of Application-Specific L1 Cache Translation Functions of the LEON3 Processor
2020
Reconfigurable caches offer an intriguing opportunity to tailor cache behavior to applications for better run-times and energy consumptions. While one may adapt structural cache parameters such as cache and block sizes, we adapt the memory-address-to-cache-index mapping function to the needs of an application. Using a LEON3 embedded multi-core processor with reconfigurable cache mappings, a metaheuristic search procedure, and Mibench applications, we show in this work how to accurately compare non-deterministic performances of applications and how to use this information to implement an optimization procedure that evolves application-specific cache mappings.
