Terrestrial Magnetism and Atmospheric Electricity, 1942
A magnetic storm of medium intensity for this Observatory started at about 07h 26m GMT, March 1, 1942. The ranges of the storm were: D, 38′.2; H, 224 gammas; Z, 205 gammas. Giant pulsations appeared on all three traces (D, H, and Z), at about 14h 30m GMT and continued for 3‐1/2 hours. These pulsations are unique in our experience at this Observatory.

Giant micropulsations at Abisko
Terrestrial Magnetism and Atmospheric Electricity, 1931At the Geophysical Observatory of Abisko, Swedish Lapland, a set of Toepfer variometers has been in operation since midsummer 1921, with a break of one month only in October to November 1927, when more rigid mountings were made. The time‐scale has been 20 mm per hour and sensitivities of 5γ in eastward, 10γ in northward, and 8γ in vertical component ...

Subthreshold Diode Micropulse Laser: A Review
Seminars in Ophthalmology, 2016The subthreshold diode micropulse laser is a form of non-damaging thermal laser therapy which has shown efficacy in multiple retinal conditions. The purpose of this article is to review the use of subthreshold diode micropulse laser as an emerging treatment modality for the treatment of retinal disease.

Journal of Geophysical Research, 1968
Spectrograms of pearl (Pc 1) micropulsations show dotted rising tones. It is suggested here that the dot structure is due to interference between the two components of a double tone or ‘hook.’ The observed dot structure could be produced by a nonconvective cyclotron instability of protons of about 100-kev energy and 60° pitch angle.

Micropulsation activity at Lerwick
Journal of Atmospheric and Terrestrial Physics, 1968Abstract A handscaled analysis of micropulsation activity at Lerwick Observatory has been carried out which shows some agreement with previous handscaled work using different equipment. Day and nighttime activity are confirmed to occupy essentially different period ranges, and a correlation of Pi activity with acceptable auroral zone current models ...

Piezoelectric stapedotomy: the importance of a micropulse program
Acta Oto-Laryngologica, 2010We can consider the micropulse program as the best level of safety that should be used in all cases of piezoelectric stapedotomy.The aim of this study was to describe the importance of a micropulse program in determining the success of piezoelectric stapedotomy.A total of 112 patients (group A) affected by primary otosclerosis underwent piezoelectric ...

Micropulsations and the Diagnostics of the Magnetosphere
1970Experimental and theoretical research indicates that short-period geomagnetic micropulsations are a sensitive indirect means of determining changes in the state of the upper atmosphere. L.R. O. Storey (1953) found that the space between the outer boundary of the magnetic field and the ionosphere is filled with plasma so that any disturbance reaching ...
