The appearances in a bronchogram of the more proximal branches of the bronchial tree are well known and have been fully described (Huizinga and Smelt, 1949; Twining and Kerley, 1951; Fischer, 1953; Brock, 1954; Ritvo, 1956). This is not so in regard to the more distal and final branches, and there is, moreover, some confusion as to which structures are outlined by the contrast medium at the per...

Motivated by observations about twining plants we study the static equilibrium solutions of untwisted, elastic rods in a helical shape. This work is an extension and specialization of [2]. We extend it by considering rods with intrinsic curvature and we specialize it by only considering helical solutions. Biology motivates these considerations.

Bu çalışma anaakım hukuk felsefesi literatüründen ayrılan görüşlere sahip William Twining’in küresel yaklaşımını betimleyici bir şekilde tanıtmayı amaçlamaktadır. Çok mercekli, eleştirel, bağlamsal ve olguya dayalı bakış açısını temel alan Twining, küreselleşmenin ortaya çıkardığı sorunları ele almak üzere biliminin nasıl çerçeve sunması gerektiğini tartışmaktadır. Söz konusu çerçeve, 21. yüzyı...

The curvature of the helical trajectory formed by herbaceous stem-twiners has been hypothesized to be constant on uniformly sized cylindrical supports and remains constant on different supports varying in diameter. However, experimental studies on the constant curvature hypothesis have been very limited. Here, we tested the hypothesis in a series of experiments on five herbaceous stem-twiners (...

Parasitic twining is a rare type of monozygotic monochorionic monoamniotic asymmetrical conjoined twin. We report a case of epigastric heteropagus twin. An ultrasound scan showed a defect of 1.5 cm in the epigastrium. CT showed soft tissue lobulated mass with fat and air components coming out of the epigastric defect. At operation rudimentary alimentary canal with no viscera, was found in the p...
