We investigated the effects of eight temperatures (22.5, 25.0, 27.5, 30.0, 32.5, 35.0, 37.5, and 40.0 degrees C) and four relative humidities (43, 55, 63, and 75%) on population growth and development of the psocid Liposcelis rufa Broadhead (Psocoptera: Liposcelididae). L. rufa did not survive at 43% RH, at all temperatures tested; at 55% RH, at the highest four temperatures; and at 63% RH and ...

Abstract Development of 3 H, 14 C, 41 Ca, 55 Fe and 63 Ni radiochemical analysis methods were carried out independently by two laboratories using both inactivate activated concrete samples. Two preliminary radioanalytical procedures for the non-volatile radionuclides ( Fe, Ni) one Thermal oxidation method volatile C) developed. The difficulties in development results are discussed.

Three binaries are now established sources of emission at very high energies (>10 eV). They are composed of a massive star and a compact object. The emission can be due to the interaction of the relativistic wind from a young ms pulsar with the stellar wind of the companion (Maraschi & Treves, 1981), by which rotation-power ends up as non-thermal flux. Variations at VHE energies are explained a...
