BACKGROUND The morning surge of blood pressure (BP) is associated with alpha-adrenergic activity. We studied the association between the alpha-adrenergic morning surge in BP and silent cerebrovascular disease in elderly patients with hypertension. METHODS We conducted ambulatory BP monitoring three times (twice at baseline and after nighttime dosing of the alpha1-blocker doxazosin) in 98 elde...

Morning blood pressure (BP) surge is considered to be an independent risk factor for cardiovascular diseases. We tested the hypothesis that increased large-artery stiffness and impaired sympathetic baroreflex sensitivity (BRS) contribute to augmented morning surge in elderly hypertensive subjects. Morning surge was assessed as morning systolic BP averaged for 2 h just after waking up minus mini...

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...

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...

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...

The recent discovery of magnetic skyrmion lattices initiated a surge of interest in the scientific community. Several novel phenomena have been shown to emerge from the interaction of conducting electrons with the skyrmion lattice, such as a topological Hall-effect and a spin-transfer torque at ultra-low current densities. In the insulating compound Cu2OSeO3, magneto-electric coupling enables c...

The sudden surge toward nuclear power throughout the world has given rise to some serious questions about its potential effect on many facets of our complex civilization. The social, economic, military, and geopolitical implications are staggering and far beyond the comprehension of most of us. Of immediate and practical concern to all, however, is the impact of nuclear power on our local envir...
