Abstract Bare sandy flats at and below low tide level of the Wadden Sea (eastern North Sea, European Atlantic) were observed in 2020 to have been invaded by an introduced grass-like alga, Vaucheria cf. velutina (Xanthophyceae). A dense algal turf accumulated stabilized mud, where resident seniors lugworm Arenicola marina had reworked rippled sand . Algae worms incompatible. Initially, rising pa...

In semi-arid regions, infiltration of rain water into the soil is significantly higher in vegetated areas than for bare ground. However, quantitative data on the dependence of infiltration capacity on plant biomass is very limited. In this paper, we use a simple reaction-diffusion-advection model to investigate the effects of varying the strength of this dependence. We begin by studying the for...

This study presented a model-based image-matching (MBIM) motion analysis technique for ankle joint kinematic measurement. Five cadaveric below-hip specimens were manipulated through a full range of ankle joint motions in bare-foot and shoed conditions. The ankle motions were analyzed by bone-pin marker-based motion analysis and MBIM motion analysis techniques respectively. The root mean square ...

[1] The sea ice cover of the Chukchi and Beaufort Seas is currently undergoing a fundamental shift from multiyear ice to first‐year ice. Field observations of sea ice physical and optical properties were collected in this region during June–July 2010, revealing unexpectedly complex spatial distributions of solar radiation under the melt‐season ice cover. Based on our optical measurements of fir...

During three consecutive years (1991-93), a field experiment was conducted in 3n intensively irrigated agricultural sail in SW Spain. The maio objective of tbis study was to determine the water flow and nitrate leaching below tbe root zone~ under an irrigated maize crop and after the growing season (bare soil and rainy periad). The experiment was carried out on a furrow irrigated maize crop usi...

Some considerations showing that renormalizable theories with consistent per-turbative series can not be nonperturbatively finite (in terms of bare parameters) are provided. Accordingly any fundamental unified theory has to be either non-renormalizable or order by order finite. Renormalization procedure serves well for extracting physical information from renor-malizable theories. Wilson's reno...

Osteomyelitis variolosa is an infection of bone and joints by smallpox virus variola major, most commonly in the elbows, wrists, ankles, hands, and feet. We report one such case in a 70-year-old woman who presented with deformities of the right knee, both elbows and ankles, and the left hand, and a history of childhood fever with rashes. Her lateral femoral condyle of the right knee was hypopla...
