D2.2. LITES luminaires produced

The Deliverable D2.2. “LITES luminaires produced” deals with Task 2.3. “Toolkits fabrication for luminaires’ production” and Task 2.4. “Production of the final LITES luminaires”. The objective of this Deliverable is to allow preparing the embedding of all LITES subsystems (power supply, sensors, antenna, etc...), Integrate of all the subcomponents into the luminaires and check (test) the mechanical, electrical ...

Scenedesmus obliquus as feedstock for biohydrogen production by Enterobacter ae...

Hydrogen (H2) gas is seen as an ideal future energy carrier because it is easily converted into electricity in fuel cells, liberates a large amount of energy per unit mass, and generates no air pollutants. In this work, biological hydrogen (bioH2) was produced from the microalgal biomass of Scenedesmus obliquus which was used as a substrate for the fermentation by Enterobacter aerogenes ATCC 13048 and Clostridi...

Fructophilic behaviour of Gordonia alkanivorans strain 1B during dibenzothiophe...

Biodesulfurization (BDS) aims at the removal of recalcitrant sulfur from fossil fuels at mild operating conditions with the aid of microorganisms. These microorganisms can remove sulfur from dibenzothiphene (DBT), a model compound, or other polycyclic aromatic used as sulfur source, making BDS an easy and environmental friendly process. Gordonia alkanivorans strain 1B has been described as a desulfurizing bacte...

Folded-cascode transimpedance amplifiers employing a CMOS inverter as input stage

This paper presents the design and comparison of two shunt feedback transimpedance amplifiers (TIAs) implemented in standard 350nm CMOS technology from Austria Microsystems. These transimpedance amplifiers are based on a folded cascode topology. The first one is a conventional folded-cascode (CFC-TIA) and the second is a modified version folded-cascod (MFC-TIA) employing a CMOS inverter at the input stage. The ...

A história local como estratégia para o ensino da História

A função social da História

O estado da História : o ensino

In spite of recurrent criticisms, the role of History, as a subject included in the basic and secondary leveis of teaching, is internationally, socially and individually recognized. The studies made emphasize its potential role in building a history and national identity capable of resisting to an overwhelming and amorphous globalisation. Society expects that its didactic function guaranties the preservation of...

O brasileiro : ausência e presença no Portugal oitocentista

Ensino técnico : da formação de produtores ao capital humano

O ensino na segunda metade do século XIX

The politicai stability achieved in the second half of the nineteenth century, although the vicissitudes resulting from rotativism, created the fundamental conditions for the implementation of some signi-ficant reforms of the educational system. Based on the spirit and ideas produced in the 1820's, 1850's and 1870's, the legislators sought to push Portugal closer to the leveis of culture and education of other ...
