Pulsed electron paramagnetic resonance (EPR) is an electron paramagnetic resonance technique that involves the alignment of the net magnetization vector of the electron spins in a constant magnetic field. This alignment is perturbed by applying a short oscillating field, usually a microwave pulse. One can then measure the emitted microwave ...
Meltwater pulse 1B. Postglacial Sea level Rise Curve and Meltwater Pulses (MWP) Meltwater pulse 1B ( MWP1b) is the name used by Quaternary geologists, paleoclimatologists, and oceanographers for a period of either rapid or just accelerated post-glacial sea level rise that some hypothesize to have occurred between 11,500 and 11,200 calendar ...
A high-carb meal may trigger palpitations if you have low blood sugar. Likewise, an extra cup of coffee or a caffeine-packed energy drink may get your heart racing and your head buzzing a little ...

A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics .
On 6 and 9 August 1945, the United States detonated two atomic bombs over the Japanese cities of Hiroshima and Nagasaki. The bombings killed between 129,000 and 226,000 people, most of whom were civilians, and remain the only use of nuclear weapons in an armed conflict. Japan surrendered to the Allies on 15 August, six days after the bombing of ...
In the 2009–2010 school year, Medway High School's chess team became the first to win all five local tournaments held in Thames Valley District School Board. In the nearly 20-year history of these tournaments, this feat has never before been accomplished. The same chess team was the first to win every game played (20-0-0) in a single tournament.
Pulsed laser. Pulsed operation of lasers refers to any laser not classified as continuous wave, so that the optical power appears in pulses of some duration at some repetition rate. [1] This encompasses a wide range of technologies addressing a number of different motivations. Some lasers are pulsed simply because they cannot be run in ...
