Lobster claw leg.
His right leg was shorter than the left and ended in a conical stump. The foot had a well developed big toe and rudimentary second toe, and was located halfway up the lateral aspect ofthe leg (Fig. 1). The lateral three toes were absent. He could grasp the examiner’s two fingers firmly with this clawlike malformation and pick up a rubber ball 4 cm in diameter. His hips, femora, knees, left leg ...
متن کاملLeg Design and Control for Fast Locomotion
Motivation: A linear spring-like leg behavior is found in human and animal running [4, 2]. Although some technical systems were able to mimic running with such elastic legs within a range of different speeds and gaits [7, 8] it is still not known why biological legs employ this behavior. Until now there is no running robot with segmented legs. With regard to the reduced contact times at high sp...

this study intends to investigate samuel beckett’s waiting for godot and endgame under the lacanian psychoanalysis. it begins by explaining the most important concepts of lacanian psychoanalysis. the beckettian characters are studied regarding their state of unconscious, and not the state of consciousness as is common in most beckett studies. according to lacan, language plays the sole role in ...
Influence of Soft or Hard Floors before and after First Calving on Dairy Heifer Locomotion, Claw and Leg Health
Claw health, an important dairy cow welfare parameter, may be affected by early-life foot/leg stresses. To investigate this, groups of pregnant heifers were allocated to deep straw bedding (Soft) or cubicles (Hard), both with scraped concrete feeding alleys. After the grazing season, they were re-housed in cubicle systems, half on slatted concrete (Hard) and half on slatted rubber (Soft) alleys...
متن کاملDetection of quantitative trait loci affecting lameness and leg conformation traits in Danish Holstein cattle.
Lameness is an important factor for culling animals. Strong legs and feet improve herd life of dairy cows. Therefore, many countries include leg and feet conformation traits in their breeding programs, often as early predictors of longevity. However, few countries directly measure lameness related traits to include these in a breeding program. Lameness indices in 3 different lactations and 5 le...
