El sincrotró ALBA, una eina de futur

Els sincrotrons, com l'ALBA, són un tipus d'accelerador de partícules que tenen un gran nombre d'aplicacions en gran diversitat de camps. Són també una de les inversions actualment més importants en el món de la física ja que permeten -i seguiran permetent en un futur proper- mostrar a l'ésser humà tot allò que el seu ull no és capaç de veur

The Design and Evaluation of a Knowledge-intensive System

AbstractTo make an appropriate decision, a manager needs to be supported with qualified information and adequate knowledge in interpreting the information. A challenging situation arises when the manager has only limited time for formulating an appropriate decision. One of the solutions is to support the manager with a Knowledge-intensive System (KIS). The paper presents the findings of an evaluation of a KIS called Leading to Information Access (LIA). There are four principal components in the evaluation of LIA, namely (1) an acceptable satisfaction level in using LIA, (2) good assessment of LIA s performance, (3) an acceptable level of computer literacy, and (4) a high confidence of LIA s usefulness

Surface and electronic structure of MOCVD-grown Ga(0.92)In(0.08)N investigated by UV and X-ray photoelectron spectroscopies

The surface and electronic structure of MOCVD-grown layers of Ga(0.92)In(0.08)N have been investigated by means of photoemission. An additional feature at the valence band edge, which can be ascribed to the presence of In in the layer, has been revealed. A clean (0001)-(1x1) surface was prepared by argon ion sputtering and annealing. Stability of chemical composition of the investigated surface subjected to similar ion etching was proven by means of X-ray photoemission spectroscopy.Comment: 13 pages, 6 figure

Potential for comparative public opinion research in public administration

The public administration and public services have always taken a marginal place in the political scientists’ behavioural research. Public administration students on the other hand tend to focus on political and administrative elites and institutions, and largely ignored citizens in comparative research. In this article we make a plea for international comparative research on citizens’ attitudes towards the public administration from an interdisciplinary perspective. Available international survey material is discussed, and main trends in empirical practice and theoretical approaches are outlined, especially those with a potential impact on public sector reform

Study of the deformation-driving vd5/2 orbital in 6728Ni39 using one-neutron transfer reactions

Abstract The ν g 9 / 2 , d 5 / 2 , s 1 / 2 orbitals are assumed to be responsible for the swift onset of collectivity observed in the region below 68Ni. Especially the single-particle energies and strengths of these orbitals are of importance. We studied such properties in the nearby 67Ni nucleus, by performing a ( d , p ) -experiment in inverse kinematics employing a post-accelerated radioactive ion beam (RIB) at the REX-ISOLDE facility. The experiment was performed at an energy of 2.95 MeV/u using a combination of the T-REX particle detectors, the Miniball γ-detection array and a newly-developed delayed-correlation technique as to investigate μs-isomers. Angular distributions of the ground state and multiple excited states in 67Ni were obtained and compared with DWBA cross-section calculations, leading to the identification of positive-parity states with substantial ν g 9 / 2 (1007 keV) and ν d 5 / 2 (2207 keV and 3277 keV) single-particle strengths up to an excitation energy of 5.8 MeV. 50% of the ν d 5 / 2 single-particle strength relative to the ν g 9 / 2 -orbital is concentrated in and shared between the first two observed 5 / 2 + levels. A comparison with extended Shell Model calculations and equivalent (3He, d) studies in the region around 9040Zr50 highlights similarities for the strength of the negative-parity pf and positive-parity g 9 / 2 state, but differences are observed for the d 5 / 2 single-particle strength
