Results from new fungus-tolerant grapevine varieties for Organic Viticulture

Two red and three white new fungus-tolerant grape varieties were tested within a period of five years. REGENT, RONDO, JOHANNITER and Gf 48-12 show a better wine quality than PINOT NOIR or SILVANER and can be recommended for Organic Viticulture as well as for the conventional viticulture to reduce copper and fungicide applications

Brain Potentials During Silent and Oral Reading

Brain potentials have been recorded during silence, during silent reading, and oral reading. While it has been assumed that potentials cannot be picked up during strong, complex stimulation, the results indicate that they can be. Analysis of the data indicates a hypothesis to the effect that complexity of cortical functioning is associated with complexity of the electrical activity of the cortex

An Analysis of the Berger Rhythm, with Special Reference to the Duration and Amplitude of the Individual Wave

The rhythmical electrical potential waves recorded from the human brain have been classified by their discoverer, Berger2 into two types: alpha-waves, and beta-waves. This classification is made on the basis of the duration and amplitude of the waves. Waves having a duration of about .10 sec. and an amplitude of about 20 microvolts fall into the category of alpha-waves. Waves having a duration of about .04 sec. and an amplitude of about 10 microvolts make up the beta-waves. In general, the beta-wave is formed on the sides of the larger and more predominant alpha-wave
