La recherche de sources d’énergie fiables ayant un faible coût environnemental est en plein essor. L’hydrogène, étant un transporteur d’énergie propre et simple, pourrait servir comme moyen de transport de l’énergie de l’avenir. Une solution idéale pour les besoins énergétiques…

The RBE values for neutrons vary to a wide range and the influencing factors have been discussed. The relevance of cytogenetic end points as signature of the past neutron exposure, and the importance of cosmic component of neutron have been…

A utilização da modelagem matemática pode contribuir para aumentar o conhecimento em sistemas de produção animal, possibilitando a identificação, compreensão e quantificação das interações e problemas nestes sistemas. Por este motivo, o objetivo deste trabalho foi desenvolver um modelo para…

The shift towards global networking brings with it many opportunities and challenges. In this paper, we discuss key technologies in achieving global semantic interoperability among heterogeneous information systems, including both traditional and web data sources. In particular, we focus on…

This paper presents the results of an ongoing effort to develop a direct solder bumping process for electronics packaging. The proposed process entails delivering molten droplets onto specific locations on electronic devices to form solder bumps. This study is focused…

Cycle-to-cycle control is a method for using feedback to improve product quality for processes that are inaccessible within a single processing cycle. This limitation stems from the impossibility or the prohibitively high cost of placing sensors and actuators that could…

Nous étudions le ribozyme VS de Neurospora, en tant que système modèle, pour
augmenter nos connaissances sur la relation entre la structure et la fonction chez les ARNs,
ainsi que pour mieux comprendre le mécanisme de clivage de ce ribozyme.…
