Background To assess the usefulness of premature luteinization hormone (LH) surge prevention in an intrauterine insemination (IUI) cycle by GnRH antagonist administration MaterialsAndMethods Sixty patients with unexplained or mild male infertility or minimal to mild endometriosis were enrolled in this prospective randomized controlled trial. There were twenty patients in group A (with GnRH anta...

I study a market in which a profit-maximizing intermediary facilitates trade between buyers and sellers. The intermediary sets prices for buyers and sellers, and keeps the difference as her fee. Optimal prices increase when demand increases, i.e., shifts right. If a demand increase is due to an increase in the number of ex ante similar buyers, then the intermediary’s optimal percent fee decreas...

Hurricane Sandy in late October 2012 drove before it a storm surge that rose to 4.28 meters above mean lower low water at The Battery in lower Manhattan, and flooded the Hugh L. Carey automobile tunnel between Brooklyn and The Battery. This study examines the surge event in New York Harbor using the Weather Research and Forecasting (WRF) atmospheric model and the Coupled-Ocean-Atmosphere-Wave- ...

We investigate tropical cyclone wind and storm surge damage reduction for five areas along the Miami-Dade County coastline either by hardening buildings or by the hypothetical application of wind-wave pumps to modify storms. We calculate surge height and wind speed as functions of return period and sea surface temperature reduction by wind-wave pumps. We then estimate costs and economic losses ...

Throttle surge tanks are a part of high head powerplants. The main consequence of a throttle placement is to introduce head losses by accelerating the flow. They make it possible to manage extreme water levels during mass oscillations while increasing water surge, e.g. water hammer, in the headrace tunnel. This phenomenon happens every time the flow discharge is changed in the waterway. Either ...

The development and upgrade of test installations, instrumentation and the data acquisition system of an existing turbofan engine test rig are described for an experimental program which was planned and initiated to investigate the transient unsteady operation of gas turbine engines with an emphasis on compressor operation. The objective of the program was to examine aerodynamic instabilities s...

In his article "Literary Geography and Comparative Literature" César Domínguez analyzes the relevance of political and linguistic frameworks for comparative literary historiography in the context of the European Union. Domínguez's discussion is based on the notion of geoculture whose theorization from Immanuel Wallerstein's perspective presents paradigms of interest to comparative literature. T...
