—Surface roughness is a crucial input for radar backscatter models. Roughness measurements of root mean-squared height (h rms) of the same surface can vary depending on the measuring instrument and how the data are processed. This letter addresses the error in h rms associated with instrument bias and instrument deployment issues such as number and length(More)
Remote sensing techniques for monitoring soil moisture were tested by comparing hyperspectral reflectance and spectral indexes; surface temperature (T s) and thermal indexes; and normalized radar backscatter to soil moisture. A laboratory study indicated that hyperspectral reflectance and T s were sensitive to surface soil moisture (r 2 range from 0.72 to(More)
Transmission of the fox tapeworm Echinococcus multilocularis, the causative agent of human alveolar echinococcosis, is known to depend on various environmental factors which are subject to human influence. Epidemiological data suggest that in most endemic regions anthropogenic landscape changes (e.g. deforestation and agricultural practices) have led to(More)
The Integral Equation Method (IEM) model and a newly defined delta index were used to estimate near surface soil moisture from C-band radar satellite imagery in a semi-arid rangeland in southern Arizona, USA. Model results were validated against soil moisture measurements made in the field at the time of satellite overpass. The IEM model performed poorly in(More)
An ectopic pregnancy after a hysterectomy is a rare event, with about 40 reported cases since it was first identified by Wendeler in 1895. There are even fewer cases reported of an ectopic pregnancy occurring years after a hysterectomy has been performed. This case illustrates the sonographic and computed tomographic (CT) findings in the setting of(More)
This study aims to show that sensitive detection of ethyl glucuronide in dried blood spotted onto various surfaces after a period of 24h is feasible. At present, there is insufficient information how tightly ethyl glucuronide (EtG) binds to various materials and how easily it can be eluted. 4ml aliquots of blood samples obtained from seven volunteers after(More)
PURPOSE To report three patients with an unilateral morning glory disc anomaly in association with an ipsilateral mild thickening of the optic nerve. METHODS Three children with a morning glory disc anomaly underwent a magnetic resonance imaging (MRI) of the brain. Ophthalmological, genetic and MRI findings at follow-up are reported. A literature search(More)
