The synthesis of sorption materials for retention and/or preconcentration of species of clinical and environmental interest, such as metal ions, is an important area of contemporary research. We report herein the synthesis of different solid supports of anthracene-phosphine sulfide for Cu(II) and Pb(II) preconcentration. Sensing properties of these materials were also evaluated using a flow-through optosensing ...
RESUMO Os autores apresentam o caso clínico de uma criança de sete anos de idade com neutropenia autoimune severa e crónica, refractária à terapêutica, que deu entrada em choque séptico associado a lesões inflamatórias flictenulares perianais. Foi instituída terapêutica antibiótica de largo espectro com cobertura para anaeróbios associada a Imunoglobulina endovenosa em doses elevadas e Filgastrim. A criança man...
This paper discusses hadron energy reconstruction for the ATLAS barrel prototype combined calorimeter (consisting of a lead-liquid argon electromagnetic part and an iron-scintillator hadronic part) in the framework of the non-parametrical method. The non-parametrical method utilizes only the known e/h ratios and the electron calibration constants and does not require the determination of any parameters by a min...
A new combined test of an electromagnetic liquid argon accordion calorimeter and a hadronic scintillating-tile calorimeter was carried out at the CERN SPS. These devices are prototypes of the barrel calorimeter of the future ATLAS experiment at the LHC. The energy resolution of pions in the energy range from 10 to 300 GeV at an incident angle [theta] of about 12° is well described by the expression , where E is...
The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter presents a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behaviour is obtained. The underlying radial energy densities for the four depth...
