Primary hyperparathyroidism (PHPT) in pregnant women is an uncommon disease. It could be easily misdiagnosed because of physiologic changes during pregnancy; in some cases, patients could remain asymptomatic maintaining elevated calcium serum levels, and this situation represents a threat to the health of both mother and fetus. We present two cases of PHPT(More)
Neutron capture cross sections of actinides are of great relevance for the Transmutation of Nuclear Waste in Accelerator Driven Systems (ADS) and Generation-IV reactors. The neutron capture cross sections of 237 Np and 240 Pu were measured at the n TOF facility with a Total Absorption Calorimeter. The data have been analyzed with the SAMMY code. The(More)

We have measured the neutron capture and fission cross section of 233 U at the neutron time-of-flight facility n TOF at CERN in the energy range from 1 eV to 1 MeV with high accuracy by using a high performance 4π BaF 2 Total Absorption Calorimeter (TAC) as a detection device. The method, based on the TAC energy response study, allowing to disentangle(More)

The neutron capture cross-section of 234 U has been measured for energies from thermal up to the keV region in the neutron time-of-flight facility n TOF, based on a spallation source located at CERN. A 4π BaF 2 array composed of 40 crystals, placed at a distance of 184.9 m from the neutron source, was employed as a total absorption calorimeter (TAC) for(More)
BACKGROUND AND OBJECTIVE The aim of this study was to assess the utility of arterial calcium stimulation with hepatic venous sampling (ASVS) in the localization of tumors in patients with endogenous hyperinsulinism not detected with other methods. PATIENTS AND METHODS We performed a retrospective study of 26 patients admitted to our hospital for(More)
Neutron resonance spectroscopy plays an important role in the investigation of neutron induced reaction cross sections and nuclear structure in the MeV excitation range. Neutron time-of-flight facilities are the most used installations to explore neutron resonances. In this paper we describe the basic features of neutron resonance spectroscopy together with(More)

Two different detectors and techniques are employed at n TOF facility, at CERN, to improve the accuracy of the neutron capture cross section of 197 Au(n,γ): a total absorption calorimeter and a set of C 6 D 6. The accurate knowledge of this cross section is of great importance for all the (n,γ) reactions study. The neutron capture cross section and nuclear(More)
