This paper provides a general statistical methodology for modeling environmental pathogen concentrations in natural waters. A hierarchical model of pathogen concentrations captures site and regional random effects as well as random laboratory recovery rates. Recovery rates were modeled by a Generalized Linear Mixed Model. Two classes of pathogen(More)
Transmission losses (TL) are complicated phenomena that characterize the processes of evapotranspiration and infiltration as water moves down a stream. This analysis focuses on transmission losses that occur within the stream and can be computed with data from tandem stream gauges. Data from Walnut Gulch Experimental Watershed (WGEW), in southeast Arizona,(More)
A clinical and cadaveric example show the EndoButton (Acufex Microsurgical Inc, Mansfield, MA), used for anterior cruciate ligament endoscopic fixation, flipping outside the extensor mechanism or vastus lateralis rather than flipping directly outside the lateral femoral cortex. This pitfall was caused by overdrilling the femoral socket beyond the(More)
