1. HOLMIUM-166M: MULTI-GAMA STANDARD TO DETERMINE THE ACTIVITY OF RADIONUCLIDES IN SEMICONDUCTOR DETECTORS. / HÓLMIO-166M: PADRÃO MULTI-GAMA PARA A DETERMINAÇÃO DE ATIVIDADE DE RADIONUCLÍDEOS POR MEIO DE DETECTORES SEMICONDUTORES / HOLMIO-166M: PADRÓN MULTI-GAMMA PARA LA DETERMINACIÓN DE ACTIVIDAD DE RADIONUCLÍDEOS
The efficiency and calibration curves as function of gamma- ray energy for a germanium detector are usually established by using many standard gamma-ray sources of radionuclides decaying with few gamma rays or radionuclides having complex decay scheme, as 152 Eu or 133 Ba. But these radionuclides cannot be used alone, because they have a few gamma lines with

2. State-dependent radial elasticity of attached cross-bridges in single skinned fibres of rabbit psoas muscle.
1. In a single skinned fibre of rabbit psoas muscle, upon attachment of cross bridges to actin in the presence of ADP or pyrophosphate (PPi), the separation between the contractile filaments, as determined by equatorial X-ray diffraction, is found to decrease, suggesting that force is generated in the radial direction. 2. The single muscle fibres were subjec
