NEW URBAN SPACES: URBAN THEORY AND THE SCALE QUESTION BY NEIL BRENNER

It can be a common thought, but there´s no doubt that urban spaces and cities are undergoing very significant transformations today. The challenge of urban restructuring today affects practically the entire global space, especially large metropolises, but also cities on an intra-urban scale. It is a process indisputably associated with the capitalist production of space carried out at multiple scales and dimens...

Bílis como matriz alternativa ou complementar na análise de drogas de abuso e b...

A bílis é um fluído corporal que contribui para a purificação do fígado, sendo uma das vias de eliminação de xenobióticos e metabolitos que, uma vez presentes na bílis, são excretados nas fezes. Na ausência ou insuficiência da amostra de sangue, em situação post-mortem, a bílis pode ser colhida através da punção direta na vesícula biliar e consequente aspiração. Esta matriz é considerada uma amostra alternativa...

NOVA GERAÇÃO DE POLÍTICAS DE HABITAÇÃO EM PORTUGAL:

O lançamento da iniciativa Nova Geração de Políticas de Habitação (NGPH) representa um momento discursivo governamental inovador na tentativa de resolução dos problemas estruturais que se têm colocado ao avanço do Direito à Habitação no nosso país. Todavia, persistem, em termos operacionais e práticos, inúmeras contradições. A construção do ensaio partirá de postulados ou conceitos já estabelecidos na literatur...

Autonomous RPCs for a Cosmic Ray ground array

We report on the behaviour of Resistive Plate Chambers (RPC) developed for muon detection in ultra-high energy cosmic ray (UHECR) experiments. The RPCs were developed for the MARTA project and were tested on field conditions. These RPCs cover an area of $1.5 \times 1.2\,{m^2}$ and are instrumented with 64 pickup electrodes providing a segmentation better than $20\,$cm. By shielding the detector units with enoug...

A method for sub-sample computation of time displacements between discrete sign...

In this paper, we propose a new method for sub-sample computation of time displacements between two sampled signals. The new algorithm is based on sampled auto- and cross-correlation sequences and takes into account only the sampled signals without the need for the customary interpolation and fitting procedures. The proposed method was evaluated and compared with other methods, in simulated and real signals. Fo...

First aid drone for outdoor sports activities

Practicing sports in the outdoors as a way to reduce stress levels, improve health; and even as an incentive to improve social relations, has encouraged more and more people to leave the sedentary lifestyle to perform activities like walking, jogging, hiking, biking, among others. This trend to practice outdoor sport activities was also driven by new technological gadgets (e.g., smartphone whit special apps, fi...

Muon Array with RPCs for Tagging Air showers (MARTA)

We discuss the concept of an array with Resistive Plate Chambers (RPC) for muon detection in ultra-high energy cosmic ray (UHECR) experiments. RPC have been used in particle physics experiments due to their fast timing properties and spatial resolution. The operation of a ground array detector poses challenging demands, as the RPC must operate remotely under extreme en- vironments, with limited power and minima...

Gentrification, residential ethnicization and the social production of fragment...

Simultaneous trends for ethnicization and gentrification are contributing to the fragmentation of contemporary urban spaces. This is characterised by the emergence of new social and urban units that break the homogeneity of the modern city and lead to the development of new networks, territorially discontinuous, less neighbourhood centred and with a limited intersection. With Mouraria (Lisbon, Portugal) and San...
