Deleterious effects of electron beam radiation on allergen extracts.
BACKGROUND The recent threat to the public posed by the dissemination of Bacillus anthracis through the US postal system has resulted in increased security measures, including electron beam irradiation for the sterilization of some mail. The deleterious effects of electron beam radiation on biological products are not fully understood. OBJECTIVE The purpose of this investigation was to assess...
متن کاملBeam Poiarization Effects in High Energy Electron-positron Storage Rings
Calculations are presented of beam polarization-dependent effects in high energy e+estorage rings. The elastic scattering within a circulating bunch (Touschek scattering) leads to a net polarization-dependent effect of 5 to 10% for parameters appropriate to SPEAR, viz, E = 2.5 Gev, LIE/E = 0.05, 0 0 and 6pL = 0.6 Mev, where E. is the storage ring energy, AE is the average energy exchanged in th...
متن کاملMechanism of electron beam radiation damage on carbon nanofiber surface
This study explored the use of a high energy electron beam as the only available technique for selective area surface modification of carbon nanofibers through controlled parameters such as radiation dose, sample temperature, and environment. The application of this variable space led to the production of unique morphological features on the nanofiber surfaces. Transmission Electron Microscopy ...
متن کاملBeam-cavity Interaction in Electron Storage Rings
A formal expression is obtained for the energy loss per . . _ turn, of a rigid bunch of electrons, to a closed cy lindrical cavity with quality factor Q. -The expression is valid provided the diameter of the entrance and exit ports for the beam are small ._.. .'compared to the bunch length. The effect of the ports is studied in an independent computational method. The energy loss is numerically...
متن کاملEffects of storage duration and temperature of hydro-primed wheat seeds on seed and seedling quality
Quality of seed as a propagating organ and the most valuable input to produce crops is highly important in agriculture. Thus, the objective of this study was to compare the effects of storage temperature (15, 20 and 25 °C) and storage duration (0, 2, 4, 6 and 8 days) of hydro-primed wheat seeds of Koohdasht dry land cultivar on germination and seedling characteristics. The seeds were hydro-prim...
