Robotics can play a key role when dealing with environments that are inaccessible or hazardous for humans including ship hulls, bridge installations, oil rigs, and first reponse scenarios. Due to irregular terrain, wheeled vehicles are ineffective at traversing the necessary terrain. Legged systems are a salient solution. However, legged systems require special considerations regarding workspac...

SU M M A R Y. —Habitat selection and nesting association in four species of Charadriiformes in the Po Delta (Italy). Colony, nest site selection and interspecific associations of four breeding Charadriiformes were studied in the Po Delta, Italy, in 1991. Physical characteristics (such as length, size, distance from mainland and other islands, occurrence of small dunes, etc.) of eighteen islands...

PURPOSE The purpose of the study was to assess maximum voluntary forefoot ground reaction force during multiple one-legged hopping (F m1LH) and to determine the correlation between tibial volumetric bone mineral content (vBMC, a valid surrogate of bone strength) and F m1LH. METHODS One hundred eighty-five females (8-82 yr old) and 138 males (8-71 yr old) performed multiple one-legged hopping ...

INTRODUCTION The purpose of this study was to reproduce an experiment with diluted thyroxine and amphibians. A detailed account of the difficulties of this line of research has been published by the initial team (Endler and Scherer-Pongratz). One experiment which has been reported reproducible by the initial team and independent researchers is the effect of extremely diluted agitated thyroxine ...
