Analysis and Optimization of the Scheffler Solar Concentrator
<p>The Scheffler reflector is a new solar concentrator design which maintains a fixed focus while only having a single axis tracking mechanism. This design makes the construction and operation of high temperature solar concentrators accessible to developing nations. In this project, I wrote …

Dewey and Scheffler on the Relationship of Learning and *Inquiry
… compares the views of John Dewey and Israel Scheffler on the relationship of learning and inquiry. After examining key aspects of Dewey's educational theory and Logic, it examines some of Scheffler's major criticisms of how Dewey relates theory to practice, problem-solving to scientific …

Density-functional theory and beyond for organic electronic materials
… ist es mit der vdW-Korrektur nach Tkatchenko und Scheffler verträglich, die den langreichweitigen $1/R^6$-Beitrag mit dichteabhängigen $C_6$-Koeffizienten zu einem gegebenen DFT-Funktional hinzufügt. Alternativ können vdW-Wechselwirkungen mit Methoden erfasst werden, die auf der Random-phase …

Persons and partiality: limitations on consequentialist justifications
… assaulting and killing innocent persons. Samuel Scheffler argues that restrictions are so strong they are paradoxical. I counter this charge by arguing that restrictions need not categorically bar types of actions like killing innocent people, but rather should limit consequentialist …

Bead-basierte Fluoreszenz-Immunoassays zum Nachweis tumorinduzierter Proteine
In 2002 lung cancer was diagnosed in over 45 000 persons, 39 000 fatalities were registered. According to these statistics, lung cancer prognosis is one of the poorest. Main reason for is the late detection due to diagnosis via optical methods by which a tumor cannot be found till 300 to 400 days …

Zur Beurteilung von AR-Glasfasern in alkalischer Umgebung
AR-Glas wird in Form von Multifilamentgarn zur Verstärkung in textilbewehrtem Beton eingesetzt. Während des Herstellungsprozesses wird auf die AR-Glasfilamente die Schlichte aufgebracht, deren chemische Zusammensetzung maßgeblich die Qualität der Filament-Matrix-Grenzschicht bestimmt, sowie die …

Untersuchungen zur Replikationsstrategie des humanpathogenen Norovirus
Der Replikation des NV-Genoms geht die kotranslationale Spaltung des vom ORF1 kodierten Polyproteins durch die viruseigene Protease, voraus. Erst in cis und in trans Prozessierungen an definierten Spaltmotiven innerhalb des Polyproteins ermöglichten die Freisetzung der strukturellen und …

Validation of hygrothermal material modelling under consideration of the hysteresis of moisture storage
The achievable accuracy of hygrothermal building component simulation is significantly dependent on the applied material functions. These functions are determined by the material modelling marking the connection between the basic storage and transport parameters which are obtained from basic …

Development of a Hybrid Carrier System based on DNA Origami Nanostructures and Layer-by-Layer Microcarriers
Die vorliegende Dissertation untersuchte die Kombination von DNA-Nanostrukturen, so- genannte DNA-Origami-Strukturen, mit Layer-by-Layer (LbL) Mikrotransportern zum Auf- bau eines verbesserten Medikamententrägersystems. Dies sollte die jeweiligen Vorteile der eigenständigen Systeme kombinieren um …

Privacy enforcement with data owner-defined policies
This thesis proposes a privacy protection framework for the controlled distribution and use of personal private data. The framework is based on the idea that privacy policies can be set directly by the data owner and can be automatically enforced against the data user. Data privacy continues to be …

The influence of steel microstructure on abrasive wear in soils
A hypoeutectoid steel has been heat treated to produce a range of different hardnesses and microstructures. A simulative field test rig has been employed to determine the relationship between microstructural parameters, material properties and soil constitution. Attempts have been made to correlate …

Study of Acoustic-Gravity Wave Spectra in the Atmosphere Using Mesosphere-Stratosphere- Troposphere Radar (Propagation, Universal Spectrum)
Current research indicates that acoustic-gravity waves can greatly influence the large-scale dynamics of the middle atmosphere. The morphology and structure of the atmospheric processes which cause this phenomenon can be better understood by the study of acoustic-gravity wave spectra. In order to …

AMP-activated protein kinase and muscle metabolism
AMP-activated protein kinase (AMPK) is a major regulator of skeletal muscle metabolism with relevance to agriculture and human health. During the conversion of muscle to meat, the rate and extent of postmortem metabolism and pH decline largely determine pork quality development. Pigs with the …

Density Functional Theory Study of Aromatic Adsorption on Iron Surfaces
… has also been studied by way of the Tkatchenko-Scheffler (TS) correction. It shows a strong influence on the adsorption energies, some effect on the relative energetic ordering of sites and little to no effect on adsorption geometries. Second, the adsorption of naphthalene and quinolinium is …
