Periodical press and port cities: Creation of knowledge, representations and networks

Port cities constituted dynamic axes of national territories and stood out for their opening to the outside world for the transaction of goods, the reception of the new and the exchange of ideas. They were also free spaces for new technological experiences and the foundation of modern economic, scientific, social and political projects. They stood out as privileged territories for the establishment of networks of knowledge and through these networks maintained the contact with distant lands. Intellectual production in them is remarkable and the periodical press, providing general or specialized information, as an information industry at the service of new political, scientific and economic projects, finds space for its development within the port cities. This Special Section brings together researchers working on these subjects, allowing a multidisciplinary approach involving scholars from such scientific areas as communication, information, history, literature and international relations. The objective is to analyse the relationship between the periodic press and port cities and how these urban spaces fostered public opinion and debate projects, as well as new specialized information.info:eu-repo/semantics/acceptedVersio

Performance Evaluation of Vision-Based Algorithms for MAVs

An important focus of current research in the field of Micro Aerial Vehicles (MAVs) is to increase the safety of their operation in general unstructured environments. Especially indoors, where GPS cannot be used for localization, reliable algorithms for localization and mapping of the environment are necessary in order to keep an MAV airborne safely. In this paper, we compare vision-based real-time capable methods for localization and mapping and point out their strengths and weaknesses. Additionally, we describe algorithms for state estimation, control and navigation, which use the localization and mapping results of our vision-based algorithms as input.Comment: Presented at OAGM Workshop, 2015 (arXiv:1505.01065

Strong Anisotropy in Liquid Water upon Librational Excitation using Terahertz Laser Fields

Tracking the excitation of water molecules in the homogeneous liquid is challenging due to the ultrafast dissipation of rotational excitation energy through the hydrogen-bonded network. Here we demonstrate strong transient anisotropy of liquid water through librational excitation using single-color pump-probe experiments at 12.3 THz. We deduce a third order response of chi^3 exceeding previously reported values in the optical range by three orders of magnitude. Using a theory that replaces the nonlinear response with a material response property amenable to molecular dynamics simulation, we show that the rotationally damped motion of water molecules in the librational band is resonantly driven at this frequency, which could explain the enhancement of the anisotropy in the liquid by the external Terahertz field. By addition of salt (MgSO4), the hydration water is instead dominated by the local electric field of the ions, resulting in reduction of water molecules that can be dynamically perturbed by THz pulses

Reserva cognitiva e a severidade da doença de Alzheimer

Alzheimer's disease (AD) is a clinical syndrome caused by neurodegeneration and characterized by a progressive deterioration in cognitive ability and capacity for independent living. Cognitive reserve (CR) describes the capacity of the adult brain to cope with the effects of the neurodegenerative process and to minimize the clinical manifestation of pathology of dementia. The aim of this study was to evaluate the association of CR and the severity of AD. Method: This study was cross-sectional. Functional and neuropsychological abilities of 75 outpatients with probable AD diagnosis were evaluated. Patients completed two questionnaires, "Participation in leisure activities throughout life" and CR Questionnaire. Result: The relationship between Clinical Dementia Rating (CDR) and the level of CR was statistically significant (likelihood ratio (LR), p = 0.015). Conclusion: The level of CR influenced the severity of dementia. This study suggests that AD patients with higher CR may benefit against cognitive decline after diagnosis of AD.info:eu-repo/semantics/publishedVersio

Medidas de reserva cognitiva na doença de Alzheimer

SCIELO:S2237-60892014000300160 (Nº de Acesso Web of Science)Introduction: Cognitive reserve (CR), a hypothetical construct used to obtain information about cognitive aging, describes the capacity of the adult brain to cope with the effects of neurodegenerative processes. This study evaluated CR using a CR questionnaire (CRQ) and a set of variables (education, leisure activities, lifelong occupation) that inform CR. It also developed a CR index, validated the CRQ, and examined the correlation between the different CR measures. Methods: Functional and neuropsychological capacities of 75 outpatients (mean age: 80.2 years) with a probable AD diagnosis were evaluated. Socio-demographic data and clinical variables were collected. Patients completed two questionnaires: the Participation in Leisure Activities throughout Life questionnaire, and the CRQ. Results: Participants with a greater CR had higher scores in cognitive tests than the elderly with a lower CR. A CR index was developed. CRQ reliability was 0.795 (Cronbach’s alpha). There was a close association between the CR Index and the CRQ. Conclusions: This study found an association between CR measures and education, occupation and participation in leisure activities. The CRQ seems to be a suitable instrument to measure CR in Portuguese populations. INTRODUÇÃO: A reserva cognitiva (RC), um construto usado para informar sobre o envelhecimento cognitivo, descreve a capacidade do cérebro adulto em lidar com os efeitos de processos neurodegenerativos. Este estudo teve como objetivos avaliar a RC com o Questionário de RC (QRC) e através de variáveis (escolaridade, actividades de lazer, ocupação ao longo da vida) que informam sobre a RC; desenvolver um índice de RC; validar o QRC; e correlacionar as diferentes medidas de RC. MÉTODOS: Foram avaliadas as capacidades funcionais e neuropsicológicas de 75 doentes (idade média: 80,2 anos) com diagnóstico de provável doença de Alzheimer, seguidos em ambulatório. Os dados recolhidos incluíram variáveis sócio-demográficas e clínicas. Os pacientes completaram dois questionários: Participação em Atividades de Lazer ao Longo da Vida; e QCR. RESULTADOS: Os doentes com os níveis mais elevados de RC obtiveram os valores mais elevados nos testes cognitivos. Neste estudo foi desenvolvido um IRC. O QRC (versão portuguesa) teve uma fidelidade de 0,795 (alpha de Cronbach) e foi demonstrada uma associação alta entre o IRC e o QRC. CONCLUSÕES: Verificou-se a existência de uma associação entre as medidas de RC e a escolaridade, ocupação e participação em atividades de lazer. O CRQ pode ser considerado um instrumento adequado para medir o CR da população portuguesa

Medico-legal age estimation in a sub-adult portuguese population: validation of Atlas Schour and Massler and London

This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited."Introduction: Age estimation in children and adolescents often depends on morphological methods, such as examination of dental development. Objectives: The aim of this project was to validate, in a Portuguese population, two forensic methods of dental age estimation – Schour and Massler charts and the London atlas. Materials and Methods: The test sample was composed by 108 dental radiographs of living and known-age individuals. Dental age was estimated according to each method. Chronological age was then compared to the estimated dental age using individual t-test and paired t-test. Results: Results showed that the Schour and Massler charts underestimated age and the London atlas overestimated age. Nevertheless, the London atlas performed better in all measures. Mean differences for both the London atlas and Schour and Massler were 0,1389 and -5,4167 months respectively. Schour and Massler charts showed significant statistical difference between dental age and chronological age (p <0.05). Discussion and Conclusions: We conclude that, in the evaluated sample, age estimation using the London atlas represents an improvement in forensic age estimation from developing teeth. Further studies should be done with a larger Portuguese population sample.
