In 1909, several years before the famous `Organizer' experiments of Spemann and Mangold, Ethel Browne demonstrated induction of a secondary axis in hydra by grafting a hypostome. Based on this and subsequent work, in the late sixties, Lewis Wolpert proposed the theory of morphogen gradients and positional information. We have studied secondary axis induction by hypostome and foot tissue using t...

closed, appeared almost air-tight; the floor at one end, for a distance of about 4 feet, was covered with 3 inches of earth, evidently to allow the men to cook without endangering the wooden floor: on this were four choolas built against the side of the waggon, and several cooking pots carefully arranged; on the boards were lying the bodies of seven men in various comfortable positions, more or...

The scales used to describe the attributes of different choice options are usually open to alternative expressions, such as inches versus feet or minutes versus hours. More generally, a ratio scale can be multiplied by an arbitrary factor (e.g., 12) while preserving all of the information it conveys about different choice alternatives. We propose that expanded scales (e.g., price per year) lead...

Twenty healthy ostriches (ten cocks and ten hens), and twenty birds with tibiotarsal rotation (nine cocks and 11 hens) (14 months old) were isolated, hooded and weighed. A run (50 m x 2.5 m) was divided into sections marked 5 m, 10 m, 15 m and 20 m. Time taken for each bird to pass these points was recorded and speed computed. The degree of tibiotarsal rotation in the right foot was mean +/- SE...

background motor skills disorder in children with motor dys-function is a common disorder in childhood. the aim of this study was to investigate the prevalence and severity of musculoskeletal disorders in children with developmental coordination disorder in comparison with healthy children. material and methods using developmental disorder coordina-tion questionnaire (dcdq'07), 59 male children...

[Purpose] The purpose of this study was to determine the relationship between an accelerometer system and a foot pressure sensor system for measuring gait characteristics during walking in healthy adults. [Subjects and Methods] Thirty-five healthy participants with no neurological, musculoskeletal, or cardiopulmonary disorders volunteered for this study. Gait characteristics were measured while...
