BACKGROUND Buruli ulcer (BU) is a chronic, indolent necrotizing disease of the skin and underlying tissues caused by Mycobacterium ulcerans, which may result in functional incapacity. In 2002, Médecins Sans Frontières (MSF) opened a BU programme in Akonolinga Hospital, Cameroon, offering antibiotic treatment, surgery and general medical care. Six hundred patients have been treated in the projec...

1. We do not know which aspects of community structure and ecosystem processes are restorable for most ecosystems, yet this information is crucial for achieving successful restoration. 2. We quantified three success criteria for 8–10-year-old grassland plantings in largescale tallgrass prairie restoration (reconstruction) sites relative to three nearby prairie remnant sites. The restoration sit...

The purpose of this investigation was to find patterns (if any) that exist when comparing the dominant plant organisms atop nurse logs in two 12’x13’ quadrats along the Marsh Loop and Suspension Bridge trails at IslandWood. The intent of this investigation was to elucidate why certain plants grow on decaying wood. Two locations were chosen in the temperate second-growth forest at IslandWood. Tw...

∏ = i i e e (2.1.1) Das bedeutet, dass in einem Multiband-Modell der Gesamtfehler immer kleiner ist als der kleinste Teilbandfehler. Die Teilbandfehler werden durch das SNR in den Teilbändern bestimmt i SNR i e e min = (siehe Anhang B). Formuliert man (2.1.1) mit der Phonemerkennrate e s − = 1 und logarithmiert diesen Ausdruck, erhält man die gewünschte Additivität: ∑ − = − i i s s) 1 (log) 1 (...

The binary power law (BPL) has been successfully used to characterize heterogeneity (overdispersion or small-scale aggregation) of disease incidence for many plant pathosystems. With the BPL, the log of the observed variance is a linear function of the log of the theoretical variance for a binomial distribution over the range of incidence values, and the estimated scale (?) and slope (b) parame...
