[Daily observations (1970-1992) of fluctuations in frequency of occurrence of a sector structure in bacterial colonies selected from open air and from S. aureus cultures].
The frequencies of sector structure occurrence in different bacteria colonies (SSC) denuded from open air every day in period from 1970 to 1982 years and also in laboratory cultures Staphylococcus Aureus from 1984 to 1992 were investigated. The value SSC was expressed in percents to general number of colonies. Variations of average SSC is found out distinctly expressed opposition to 11-years cycle of Solar activity for the same period of time. The year cycle SSC was registered also with local maxima in June, August and November and global minimum in March. SSC also were observed on level of sea, on height about 1000 m over the level of sea and in gallery under the rock of thickness 1400 m (Gran Cacco, National laboratory, Assergi). The value of SSC has its maximum on height 1000 M and its minimum in gallery under the rock; it is possible, SSC depends on the intensity of space galactic rays. The results of experience, executed in April-July 1992 on cultures S.aureus have compared with average (on ten-day time periods) values for the same months of 1984-1991. Good correlation of these two curves of SSC was received. Array of measurements received from 1970 to 1992 and made conclusions can be used for long-term forecasts of cosmophysical fluctuating phenomena at least on latitude between Rome and Milano.
