A Hadron Radiation Installation and Verification Method
No full textA hadron radiation installation adapted to subject a target to irradiation by a hadron radiation beam, said installation comprising: - a target support configured to support, preferably immobilize, a target: - a hadron radiation apparatus adapted to emit a hadron radiation beam along a beam axis to irradiate the target supported by the target support, said radiation beam penetrating into the target. The radiation apparatus has a control system at least comprising a beam penetration depth control allowing at least to control and vary the penetration depth of the radiation beam into the target. The installation has a radiation beam range sensor device adapted to determine the penetration depth of said radiation beam into the target, wherein said range sensor device comprises a gamma camera responsive to prompt gamma rays that are emitted while said hadron radiation beam penetrates into the target.RST/Radiation, Science and TechnologyApplied Science

A simple method for the analysis of neutron resonance capture spectra
No full textNeutron resonance capture analysis (NRCA) is a method used to determine the bulk composition of various kinds of objects and materials. It is based on analyzing direct capture resonance peaks. However, the analysis is complicated by scattering followed by capture effects in the object itself. These effects depend on the object’s shape and size. In this paper the new Delft elemental analysis program (DEAP) is presented which can automatically and quickly analyze multiple NRCA spectra in a practical and simple way, yielding the elemental bulk composition of an object, largely independent of its shape and size. The DEAP method is demonstrated with data obtained with a Roman bronze water tap excavated in Nijmegen (The Netherlands). DEAP will also be used in the framework of the Ancient Charm project as data analysis program for neutron resonance capture imaging (NRCI) experiments. NRCI provides three-dimensional visualization and quantification of the internal structure of archaeological objects by performing scanning measurements with narrowly collimated neutron beams on archaeological objects in computed tomography based experimental setups. The large amounts (hundreds to thousands) of spectra produced during a NRCI experiment can automatically and quickly be analyzed by DEAP.Radiation, Radionuclides and ReactorsApplied Science
ESTUDO DA GESTÃO ADMINISTRATIVA SOB ENFOQUE DA GESTÃO PARTICIPATIVA NO CURSO DE CIÊNCIAS CONTÁBEIS DA FUNDAÇÃO UNIVERSIDADE FEDERAL DE RONDÔNIA
No full textEsse estudo analisa a presença da Gestão Participativa no curso de Ciências Contábeis da Fundação Universidade Federal de Rondônia por meio da utilização da Teoria da Contingência. O principal objetivo é analisar a Gestão Administrativa do Departamento de Ciências Contábeis da Universidade Federal de Rondônia no campus de Porto Velho, identificando os modelos de gestão administrativa atualmente vigente, mapeando fatores restritivos e propulsores encontrados e propor melhorias que venham eliminar ou minimiza-los. Nessa pesquisa foi aplicado o método de natureza qualitativa por meio de um estudo de caso, adotou-se a técnica de analise de conteúdo complementada por estatísticas descritivas. Como resultado do estudo, observou-se a presença de mais de um modelo de gestão dentro do departamento, mais em sua predominância há gestão burocrática, mediante a isso, foram apresentadas propostas de melhorias em cima dos pontos que foram mais evidenciados. Conclui-se que as dificuldades relatadas pelos respondentes estão distribuídas em dificuldades da gestão política e administrativa. Nesse sentido, a investigação levantada poderá servir como suporte para a construção de modelos estruturantes, assim como referencial para mudanças na unidade investigada ou em outras instituições acadêmicas
