Umbilical cord entanglement has been reported to occur in monoamniotic twins. However, it can occur in diamnionic twins due to rupture of the intertwin-dividing membrane, and is a cause for concern. A 31-year-old nullipara visited our hospital at 28+3 weeks gestation. A monochorionic diamniotic twin gestation was diagnosed ultrasonographically by visualizing a thin intertwin-dividing membrane a...

Peptidoglycan synthesis and its fine chemical composition were studied in dividing cocci of Escherichia coli carrying the lov-1 mutation and in which the coccal shape was obtained either by mecillinam treatment or by transferring a pbpA mutation (penicillin-binding protein 2- phenotype), as compared to normal rods and non-dividing cocci. Synchronously dividing cocci showed peptidoglycan synthes...

Current computing practice requires great effort to produce an application with a reliable, distributed, heterogeneous, adaptive, dynamic, real-time, parallel, secure or other execution. An exception is a bag-of-tasks application. Examples of such a type of application include the simulation of independent trials, the processing of independent media frames and the evaluation of independent cand...

Pointwise products and quotients, defined in terms of barycentric and trilinear coordinates, are extended to products P ·Γ and quotients Γ/P, where P is a point and Γ is a curve. In trilinears, for example, if Γ0 denotes the circumcircle, then P ·Γ0 is a parabola if and only if P lies on the Steiner inscribed ellipse. Barycentric division by the triangle center X110 carries Γ0 onto the Kiepert ...
