13. Estudo das derivas zonais das irregularidades de plasma ionosférico na região brasileira / Study of ionospheric zonal plasma irregularity drifts over brazilian region
A detailed study of the zonal drift velocities of the ionospheric bubbles is carried out using experimental airglow data registered at Cachoeira Paulista (22.50 S, 450 W, dip 300 S)during the period of October to March, between 1980-1994. This study is based upon 172 nights of zonal scanning photometer measurements of OI 630 nm airglow. The zonal velocity ma

14. Electric and magnetic phenomena observed before the volcano-seismic activity in 2000 in the Izu Island Region, Japan
Significant anomalous changes in the ultra low frequency range (≈0.01 Hz) were observed in both geoelectric and geomagnetic fields before the major volcano-seismic activity in the Izu Island region, Japan. The spectral intensity of the geoelectric potential difference between some electrodes on Niijima Island and the third principal component of geomagneti

15. Theodor Hellbrügge: 85 years of age – Ad multos transannos, sanos, fortunatos et beatos
We honor Theo Hellbrügge's acclaimed endeavors in the rehabilitation, or rather the prehabilitation of handicapped children. So far, he has focused on obvious handicaps, and we trust that he will include concern for everybody's silent handicaps in the future by screening for abnormal variability inside the physiological range. Therein, we introduce cis- and
