OBJECTIVE We reviewed published data describing use of beryllium lymphocyte proliferation testing (BeLPT) to determine the appropriateness of BeLPT for screening asymptomatic individuals. METHODS Published studies were identified by computerized literature searches and hand searches of relevant bibliographies and cited references. Critical assessment of evidence focused on five elements essen...

We describe the present status of future high-precision measurements of nuclear g-factors utilizing lasermicrowave double and laser-microwave-rf triple resonance methods for online-trapped, laser-cooled radioactive beryllium isotope ions. These methods have applicability to other suitably chosen isotopes and for beryllium show promise in deducing the hyperfine anomaly of Be with a sufficiently ...

A thin metallic coating is required on the inside of central detector beryllium beampipes at high-current ee colliders in order to suppress detector backgrounds that arise from scattered synchrotron radiation. As part of two CESR/CLEO upgrades, three beryllium beampipes have been coated with gold using a magnetron sputtering technique. The apparatus will be described as well as the factors that...

Enhanced diffusion of aluminum in shock activated beryllium has been observed. Cylindrical samples of aluminum coated beryllium rods were axisymetrically loaded up to 40 Gpa and a total residual strain of up to 6.74. The defect microstructure produced by both the shock wave and strain enabled the transport of aluminum in beryll~um to exceed its equilibrium solid state saturation. This "super sa...

The effect of intravenous injection of beryllium nitrate to adult female Albino rats primed with Liv.52 and to non-primed rats has been studied on various hematological parameters after 2, 10 and 30 days of such injection. There was a significant decrease in RBC count, Hb%, neutrophils, blood sugar, alkaline phosphatase, globulin and total protein values with the administration of beryllium nit...
