Busemann's concept of optimum altitude for rectilinear coasting flight has been extended to flight in a horizontal plane. The reachable domain of a vehicle in coasting flight in a horizontal plane, starting from an initial velocity, is obtained. It is shown that the area covered first increases with the altitude and then decreases to zero when the ceiling is reached. In particular, there exists...

Guided by the analogy with Rayleigh–Plesset dynamics of multielectron bubbles in superfluid He-4, we consider cosmological FLRW evolution equation additional cubic and sixth powers inverse scale factor universe. For barotropic parameter w=2∕3 (coasting universe), along zero constant absence viscous terms, using Sundman time as parameter, present parametric solutions for universe terms rational ...

background: coasting is the most common method used in the prevention of ovarian hyperstimulation syndrome (ohss) acting through vascular endothelial growth factor (vegf) reduction. however, the pregnancy rate is reported to fall with coasting when it takes more than three days. recently lowdose cabergoline, a selective d2 dopamine receptor agonist has been proven to selectively reduce vascular...

A dynamometric hubset that measures the two ground contact force components acting on a bicycle wheel in the plane of the bicycle during off-road riding while either coasting or braking was designed, constructed, and evaluated. To maintain compatibility with standard mountain bike construction, the hubs use commercially available shells with modified, strain gage-equipped axles. The axle strain...

Serum oestradiol and progesterone concentrations were examined for up to 7 days after withholding gonadotrophins whilst continuing pituitary down-regulation in 15 women at serious risk of severe ovarian hyperstimulation syndrome (OHSS) (serum oestradiol >6000 pg/ml and >15 follicles per ovary). Serum oestradiol concentrations rose on day 1 of coasting in all but two of the 15 women before falli...

In a multicentre trial, 65 in-vitro fertilization (IVF)-embryo transfer cycles were severely hyperstimulated. Instead of cancelling the cycle, gonadotrophins were withheld for a 'coasting period' until serum oestradiol concentrations had dropped below 10,000 pmol/l (mean 4.3 days), and then human chorionic gonadotrophin was administered. Four cycles were cancelled and there were 61 oocyte aspir...
