Particle transport in a karst aquifer: natural and artificial tracer experiments with bacteria, bacteriophages and microspheres (Publications)
Fast changes in spring water quality in karst areas are a major concern for production of drinking water and require detailed knowledge of the complex interaction between karst aquifer, transport beha
Evaluation of a pre-existing, 3-year household water treatment and handwashing intervention in rural Guatemala (Publications)
BACKGROUND: The promotion of household water treatment and handwashing with soap has led to large reductions in child diarrhoea in randomized efficacy trials. Currently, we know little about the healt
Public health challenges and prospects for malaria control and elimination (Publications)
The past decade witnessed unprecedented efforts to control malaria, including renewed political and financial commitment and increased availability of both old and new strategies and tools. However, m
Characterization of di-, tri-, and tetranucleotide microsatellite markers with perfect repeats for<em> Trypanosoma brucei</em> and related species (Publications)
Trypanosoma brucei, unicellular parasites causing human sleeping sickness and animal nagana, have a great impact on the socio-economic environment of sub-Saharan Africa. The dynamics of the parasite a
Effect of short-wave (6-22 MHz) magnetic fields on sleep quality and melatonin cycle in humans: the Schwarzenburg shut-down study (Publications)
This paper describes the results of a unique "natural experiment" of the operation and cessation of a broadcast transmitter with its short-wave electromagnetic fields (6-22 MHz) on sleep quality and m
Hierarchical modeling of gene-environment interactions: estimating NAT2 genotype-specific dietary effects on adenomatous polyps (Publications)
Data sparseness currently limits gene-environment interaction estimation. To improve effect estimates of gene-environment interactions, we give an overview of one approach, hierarchical modeling, and
Synthesis, DNA affinity, and antiprotozoal activity of fused ring dicationic compounds and their prodrugs (Publications)
Dicationic guanidine, N-alkylguanidine, and reversed amidine derivatives of fused ring systems have been synthesized from their corresponding bis-amines. DNA binding studies suggest that the diguanidi
