A few years ago results on cryoprotection of L-valine were reported, where the values of the critical fluence De i.e, the electron exposure which decreases the intensity of the diffraction reflections by a factor e, amounted to the order of 2000 + 1000 e/nm2. In the meantime a discrepancy arose, since several groups published De values between 100 e/nm2 and 1200 e/nm2 /1 - 4/. This disagreement and particularly the wide spread of the results induced us to investigate more thoroughly the behaviour of organic crystals at very low temperatures during electron irradiation.For this purpose large L-valine crystals with homogenuous thickness were deposited on holey carbon films, thin carbon films or Au-coated holey carbon films. These specimens were cooled down to nearly liquid helium temperature in an electron microscope with a superconducting lens system and irradiated with 200 keU-electrons. The progress of radiation damage under different preparation conditions has been observed with series of electron diffraction patterns and direct images of extinction contours.

Recently the use of a biprism in a STEM instrument has been suggested for recording of a hologram. A biprism is inserted in the illumination system and creates two coherent focussed beams at the specimen level with a probe size d= 5-10Å. If one beam passes through an object and another one passes in vacuum, an interference pattern, i.e. a hologram can be observed in diffraction plane (Fig.1).

Routine transmission of electrocardiograms and their computer interpretation via long-distance telephone lines has been proven feasible in the Automated Electrocardiogram Project of the Missouri Regional Medical Program. Though this Pilot Project — the first on a state-wide basis — is still viewed as an applied research effort rather than a service, such biotelemetry is rapidly gaining acceptance as a medium to bring modern medicine, through modern technology, to urban and remote rural areas as well, where it is most needed.The computer executes all the wave measuraments and calculations with incredible speed. It takes over a most boring, repetitive part of the physician’s work. However, it can only follow the instructions of the diagnostic program, compiled by expert cardiologists. Thus, it is an ever-ready, never-tiring servant for the physician and his patients.
