High Pressure X-Ray Preionized TEMA-CO2 Laser

The construction of a high-pressure (up to 20 atm) transversely excited CO2 laser using transverse X-ray preionization is described. High pressure operation was found to be greatly improved in comparison to UV-preionized systems. Homogeneous discharges have been achieved in the pressure range 5-20 atm, yielding a specific laser output in the order of 35 J/1. PACS: 42.55E, 42.60B Generation and ...

Aprimoramento Humano: Um Novo Tema Da Agenda Filosófica Perfeccionamiento Humano: Un Nuevo Tema De La Agenda Filosófica Human Enhancement: a New Issue in Philosophical Agenda

Since before we can remember, humanity aims to overcome its biological limitations; such a goal has certainly played a key role in the advent of technique. However, despite the benefits that technique may bring, the people who make use of it will inevitably be under risk of harm. Even though human technical wisdom consists in attaining the best result without compromising anybody’s safety, misu...

Uma introdução ao tema Recuperação de Informações Textuais

The Information Retrieval (IR) subject has always been a subject much explored in academia and in the market. The way in which academic events (i.e., congress, seminars) are conducted shows a huge maturity of area, including a very strong connection between academia and market. A lot of books on this subject have been published. However, there are few books published in Portuguese. This text at...

TEMA and Dot Enumeration Profiles Predict Mental Addition Problem Solving Speed Longitudinally

Different math indices can be used to assess math potential at school entry. We evaluated whether standardized math achievement (TEMA-2 performance), core number abilities (dot enumeration, symbolic magnitude comparison), non-verbal intelligence (NVIQ) and visuo-spatial working memory (VSWM), in combination or separately, predicted mental addition problem solving speed over time. We assessed 26...
