Background: To study the effectiveness of Clomiphene citrate (CC) in preventing a premature LH surge during controlled ovarian stimulation in women undergoing assisted reproduction. Materials and Methods: Couples were randomized to receive human menopausal gonadotrophins (hMG) followed by CC or hMG alone till the day of hCG. The primary outcomes were the incidence of a clinical pregnancy and pr...

Gulf surges are transient disturbances that propagate along the Gulf of California (GoC) from south to north, transporting cool moist air toward the deserts of northwest Mexico and the southwest United States during the North Americanmonsoon. They have been shown to modulate precipitation and have been linked to severe weather and flooding in northern Mexico and the southwest United States. The...

Human influenza A viruses (IAVs) cause global pandemics and epidemics, which remain serious threats to public health because of the shortage of effective means of control. To combat the surge of viral outbreaks, new treatments are urgently needed. Developing new virus control modalities requires better understanding of virus-host interactions. Here, we describe how IAV infection triggers cellul...

Political and economic transition is often blamed for Russia's 40% surge in deaths between 1990 and 1994. Highlighting that increases in mortality occurred primarily among alcohol-related causes and among working-age men (the heaviest drinkers), this paper investigates an alternative explanation: the demise of the 1985-1988 Gorbachev Anti-Alcohol Campaign. Using archival sources to build a new ...

A tutorial paper with a review of the technologies available in the mid-eighties for surge protection of lowvoltage end-user equipment. The principles of operation are described for “crowbar devices” (now generally described under the standardized name of “voltage switching devices”) and for “voltage clamping devices: (now generally described under the standardized name of “voltage limiting dev...

Reactive oxygen species (ROS) are required for cellular functioning and are controlled by anti-oxidants. The ROS influence the follicles, oocytes, endometrium, and their environment. The luteinizing hormone surge initiates a massive recruitment of ROS that modulates major reproductive functions namely, oocyte maturation, ovarian steroidogenesis, corpus luteal function, and luteolysis. The anti-...

This paper develops a model of the interaction between the supply of hatecreating stories from politicians and the willingness of voters to listen to hatred. Hatred is fostered with stories of an out-group’s crimes, but the impact of these stories comes from repetition not truth. Hate-creating stories are supplied by politicians when such actions help to discredit opponents whose policies benef...

During the late 1920s and early 1930s, there was a surge of anti-Semitism in Soviet Union, which considered first immediate task since 1926. This wave Judeophobia attributed to socio-economic situation, mistakes made by state authorities, chauvinism. While were some common reasons cited literature, primarily associated with imperialist past, survivals, counter-revolution. To combat anti-Semitis...

In the aftermath of a natural catastrophe there is an increased demand for skilled reconstruction labor, which leads to significant increases of reconstruction labor wages and hence insured losses. Such inflation effects are referred to as "Demand Surge" effects. It is important for insurance companies to properly account for these effects when calculating insurance premiums and determining the...

This paper describes the potential of dynamic process simulation for operators and engineering contractors as a tool to analyse and solve operational and (front-end) engineering issues. The possibilities are illustrated by a typical project involving system dynamics. The objective of this project was to evaluate the effectiveness of several alternatives to prevent surge and overheating in a com...
