The Influence of Land-use Activities on Nutrient Inputs into Upland Catchment Streams, Ghana
(2009-10-08)
In Ghana, increasing agricultural productivity is seen as an essential component of most development programs. The main objective of this study was to assess the implications of increased land-use activities on in-stream ...
Studying Galaxy-Galaxy Lensing and Higher-Order Galaxy-Mass Correlations Using the Halo Model
(2009-06-22)
In recent years, the distribution of galaxies in the Universe could be measured up to large distances and over a significant part of the sky. The analysis of this large-scale structure contains a wealth of cosmological ...
Identifikation und Charakterisierung von Interaktionspartnern des Proteins Polyduktin
(2009-04-21)
Die Autosomal-recessive polyzystische Nierenerkrankung ist eine der bedeutensten Nephropathien im Kindesalter. Die meisten Patienten präsentieren bereits in utero bilateral vergrößerte zystische Nieren und eine ...
Extracellular Phosphorylation of the Amyloid β-Peptide Promotes Aggregation
(2009-07-21)
Alzheimer’s disease (AD) is the most prevalent, progressive neurodegenerative disorder and its incidence is increasing with the aging population worldwide. The presence of extracelluar neuritic plaques containing amyloid ......
Influence of the surface roughness of hard substrates on the attachment of selected running water macrozoobenthos
(2009-07-21)
Flowing water can develop an immense force pushing on animals inhabiting the surface of stones in running waters. These animals have developed attachment devices supporting them to maintain their position against current. ...
Multi-scale chiral dynamics
(2009-07-21)
In this work, we examine two possible extensions of the low-energy effective field theory of quantum chromodynamics (QCD), called chiral perturbation theory (ChPT). Both those extensions are related to the presence of ...
Phenomenological Aspects of Mirage Mediation
(2009-03-03)
We consider the possibility that string theory vacua with spontaneously broken supersymmetry and a small positive cosmological constant arise due to hidden sector matter interactions, known as F-uplifting/F-downlifting. ...
Thianthrene and Related Heterocycles: Metal Complexes, Radical Cation Salts and Semiconductors
(2009-07-22)
Liquid SO2 was used as a solvent for complexation as well as redox reactions based on thianthrene and related heterocyclic molecules. With silver salt, AgX (X = BF4-, SbF6-), ...
Bivariant K-theory of groupoids and the noncommutative geometry of limit sets
(2009-07-21)
We present a categorical setting for noncommutative geometry in the sense of Connes. This is done by introducing a notion of morphism for spectral triples. Spectral triples are the unbounded cycles for $K$-homology ...
Bispidin-Derivate als neue nicotinische Acetylcholinrezeptor-Liganden: Synthese, In-vitro-Pharmakologie und Struktur-Wirkungsbeziehungen
(2009-10-29)
Nicotinische Acetylcholinrezeptoren (nAChR) sind ligandgesteuerte Ionenkänale, die sich aus fünf Untereinheiten zusammensetzen. Durch die Kombination verschiedener Untereinheiten (α1-α10, β1-β4, γ, δ ε) entstehen zahlreiche ......
Bispidine Derivatives as Novel Ligands for the Nicotinic Acetylcholine Receptors : Synthesis, In vitro Pharmacology and Structure-Activity Relationships
Nicotinic acetylcholine receptors (nAChRs) are ......
