Edward Wing Twining, 1887-1939.
Edward Wing Twining (Fig 1) generally is regarded as the “father” of British neuroradiology. Born on March 18th 1887, he came from a line of doctors, his grandfather and father being in family practice at Salcombe, Devon, in the south of England. He was educated at Epsom College and University College Hospital where he qualified in medicine in 1913. As a student dresser (medical student on a su...
متن کاملEstudio experimental de la efectividad de la entrevista abierta frente a la entrevista independiente de contexto
Resumen. OBJETIVO: Estudiar la efectividad relativa de las técnicas de entrevista abierta y entrevista independiente de contexto en la identificación de requisitos para sistemas software. MÉTODO: Experimento controlado ensayando dos factores: “tipo de entrevista” (abierta e independiente de contexto) y “tipo de problema” (identificación de requisitos para dos sistemas software distintos).

متن کاملLeaf damage induces twining in a climbing plant.
Successful climbing by vines not only prevents shading by neighbouring vegetation, but also may place the vines beyond ground herbivores. Here we tested the hypothesis that herbivory might enhance climbing in a vine species, and that such induced climbing should be greater in the shade. We assessed field herbivory in climbing and prostrate ramets of the twining vine Convolvulus arvensis. We eva...
متن کاملMechanics of climbing and attachment in twining plants.
Twining plants achieve vertical growth by revolving around supports of different sizes on which they exert a pressure. This observation raises many intriguing questions that are addressed within the framework of elastic filamentary structures by modeling the stem close to the apex as a growing elastic rod. The analysis shows that vertical growth is achieved thanks to discrete contact points and...
متن کاملTwining characters and Picard groups in rational conformal field theory
Picard groups of tensor categories play an important role in rational conformal field theory. The Picard group of the representation category C of a rational vertex algebra can be used to construct examples of (symmetric special) Frobenius algebras in C. Such an algebra A encodes all data needed to ensure the existence of correlators of a local conformal field theory. The Picard group of the ca...
