ABSTRACT

The continuing high profile food poisoning incidents are beginning to attract food processors using electron and gamma-ray sterilization technologies. The present method of choice uses radioactive isotopes but high-power electron particle accelerators are proving an increasingly attractive alternative. We are developing a family of compact industrial continuous wave linear accelerators which produce electrons with energies from 600 keV in increments of approximately 600 keV and with beam power of 30 kW increasing in increments of 30 kW. Here, we describe the performance of our 1st section that accelerates 15 keV gun electrons to relativistic energies and then we sketch the design of the less demanding subsequent sections that we are now constructing.

ABSTRACT

35 patients with aftereffects of cerebral stroke and 25 patients with hypertension were examined. A high rate of parodontal disease was revealed. An orthopedic stomatologic method of making metalloceramic dentures was devised.

ABSTRACT

Significant differences in the structure of the surface of prosthetic bed mucosa were revealed in healthy normal subjects and patients with after effects of cerebral stroke. The differences were observed both on the paralyzed and nonparalyzed side of prosthetic bed.
