Instrumentação e monitoramento de uma bacia hidrográfica experimental da Rede AgroHidro.

RESUMO - Estudos de longa duração em bacias hidrográ cas experimentais e representativas de uma determinada condição são importantes para um melhor entendimento da dinâmica dos processos e da resposta hidrológica de bacias a eventos diversos, gerando conhecimentos e/ou tecnologias para subsidiar o planejamento e gerenciamento dos recursos hídricos. A instrumentação e o monitoramento dependem das respostas que se deseja obter. Neste processo é importante que se tenha uma visão clara dos objetivos que se pretende alcançar em longo prazo, sendo fundamental planejar e, também, aprender com outras experiências. O presente artigo objetivou apresentar para a RedeAgroHidro a experiência em instrumentação e monitoramento adquirida em 10 anos de trabalho na bacia hidrográfica do Buriti Vermelho. ABSTRACT - Long-term studies in experimental watersheds are important to better understand the dynamics of hydrologic processes and basin response to different types of events. Knowledge and/or technologies obtained from these studies can be used to subsidize the water resources plan and management. Instrumentation and monitoring depend on the objectives and of what it is intended for the future. Therefore, it is important to plan and to learn with other experiences. The aim of this paper is to present to the AgroHidro network the experience in instrumentation and monitoring obtained in 10 years of work in the Buriti Vermelho watershed

'Preparing for the next war': the Portuguese army staff corps and the military reforms on the eve of the colonial wars

This text is part of an ongoing research project on the Portuguese Army Staff Corps, created in the first half of the 19th Century. The project focuses mainly on the period between its modern reorganization, in 1937, and its extinction in 1974. One of the main topics of the project is to evaluate and to understand the way officers from the Portuguese Army Staff Corps (ASF) played a relevant role in preparing the Portuguese Army for the colonial wars that started in Angola in 1961. Since the late 1950s many members of the ASF realized that the next armed conflicts Portugal would have to face would be the wars for national liberation in Africa, therefore, wars of counterinsurgency, very different from the conventional wars they were prepared to fight.info:eu-repo/semantics/publishedVersio

Establishing a ‘cultural base’? The creation of the Fulbright program in Portugal

This paper deals with the cultural and educational relations between the United States and Portugal during the Cold War. It is built upon the premise that cultural policies and cultural relations between states are a fundamental part of international relations. History of International Relations, therefore, should overcome an analysis based only upon political and diplomatic dimensions to address what can also be referred to as ‘cultural diplomacy’. The Cold War period, because of its historical features, is particularly relevant to the study of processes of cultural diplomacy and some authors even consider it as the ‘golden age’ of cultural diplomacy.info:eu-repo/semantics/acceptedVersio

RELOAD/CoAP architecture with resource aggregation/disaggregation service

M2M communication is expected to occur at a global level and for this reason federations of device networks are also expected. In such large scale environments, a critical issue is how to discover the available resources in a scalable manner. For this purpose CoAP Usage for RELOAD, a generic self-organizing P2P overlay network service, has been proposed to be used as a lookup service, to store available resources and as a cache for sensor data. However, such approach alone does not allow building an aggregate resource hierarchy, a very relevant issue for an efficient organization of data in future IoT applications. Here we address this issue and propose an architecture incorporating a resource aggregation/disaggregation service

HPC Cloud for Scientific and Business Applications: Taxonomy, Vision, and Research Challenges

High Performance Computing (HPC) clouds are becoming an alternative to on-premise clusters for executing scientific applications and business analytics services. Most research efforts in HPC cloud aim to understand the cost-benefit of moving resource-intensive applications from on-premise environments to public cloud platforms. Industry trends show hybrid environments are the natural path to get the best of the on-premise and cloud resources---steady (and sensitive) workloads can run on on-premise resources and peak demand can leverage remote resources in a pay-as-you-go manner. Nevertheless, there are plenty of questions to be answered in HPC cloud, which range from how to extract the best performance of an unknown underlying platform to what services are essential to make its usage easier. Moreover, the discussion on the right pricing and contractual models to fit small and large users is relevant for the sustainability of HPC clouds. This paper brings a survey and taxonomy of efforts in HPC cloud and a vision on what we believe is ahead of us, including a set of research challenges that, once tackled, can help advance businesses and scientific discoveries. This becomes particularly relevant due to the fast increasing wave of new HPC applications coming from big data and artificial intelligence.Comment: 29 pages, 5 figures, Published in ACM Computing Surveys (CSUR

Relationship and sexual quality in the wake of COVID-19: Effects of individual regulatory focus and shared concerns over the pandemic

Research has shown mixed findings regarding the effect of the COVID-19 pandemic on relation-ship and sexual quality and activity. We argue that some of these findings might be understood considering people’s predisposition to maintain safety (i.e., prevention focus) or take risks (i.e., promotion focus), and sharing concerns with one’s partner about the pandemic. A longitudinal study (N = 153) tested if regulatory focus before the pandemic (November 2019) was associated with relationship quality, sexual quality, and joint sexual activity later on (June 2020) and whether these effects were moderated by shared concerns over the pandemic. Results showed that participants more focused on prevention experienced higher relationship quality later on, but also less sexual quality and less frequent joint sexual activity, when they shared fewer (vs. more) con-cerns with their partner. In contrast, participants more focused on promotion experienced higher relationship quality later on when they shared more (vs. less) concerns with their partner. These results indicate how individuals’ regulatory focus and shared concerns in times of crisis, such as the COVID-19 pandemic, can have downstream consequences on people’s relational and sexual dynamics. We offer insights for mental health professionals to improve psychosocial health and well-being when people are faced with critical events.info:eu-repo/semantics/publishedVersio

Funções de pedotransferência para estimar capacidade de campo, ponto de murcha permanente e densidade global em solos de uma bacia hidrográfica do Bioma Cerrado.

Resumo: A grande variabilidade espacial e o elevado custo associado à obtenção de alguns parâmetros do solo dificulta a adequada representação dos sistemas agrícolas. As funções de pedotransferência (FPTs) têm sido utilizadas para estimar parâmetros do solo a partir de suas propriedades básicas. O objetivo do presente trabalho foi desenvolver FPTs para estimar a capacidade de campo (CC), o ponto de murcha permanente (PMP) e a densidade gobal (DG) em solos de uma bacia hidrográfica do Bioma Cerrado. Foram analisados dados de noventa e nove perfis de solos, com três repetições em cada uma das seguintes profundidades: 0-5 cm, 15-20 cm e 55-60 cm. Foi realizada análise de regressão múltipla para obtenção de FPTs para PMP, CC e DG, utilizado como preditores argila (ARG), silte (SLT), areia fina (AF), areia grossa (AG), matéria orgânica (MO) e DG (exceto para a FPT da DG). A seleção de preditores em cada modelo foi feita via método stepwise. As PTFs ajustadas, considerando todas as profundidades conjuntamente, foram: PMP = 0,3459 - 0,137*DG ? 0,011*MO ? 0,00066*ARG -0,00074*SLT; CC = 0,8000 - 0,371*DG ? 0,001*AG ? 0,00055*AF, com coeficiente de determinação (R2) em torno de 60%. Para DG nao foi observado bom ajuste (R2 = 10%). Abstract: Soil spatial variability and the high cost to obtain its parameters make difficult to adequately represent agricultural systems. Pedotransfer functions (FPTs) are commonly used to estimate soil parameters based on its basic properties. The objective of this work was to develop FPTs to estimate field capacity (CC), permanent wilting point (PMP) and bulk density (DG) of soils of a Brazilian Savannah catchment. Ninety nine soil profiles with three replications for each depth (0-5 cm, 15-20 cm and 55-60 cm) were analyzed. Multiple regression analyses was performed to obtain FTPs to PMP, CC and DG, using clay (ARG), silt (SLT), fine sand (AF), coarse sand (AG), organic matter (MO) and bulk density (except to FTP of DG) as predictors. Stepwise method was used to select predictors in each model. Fitted FTPs considering all depth were: PMP = 0.3459 - 0.137*DG ? 0.011*MO ? 0.00066*ARG -0.00074*SLT; CC = 0.8000 - 0.371*DG ? 0.001*AG ? 0.00055*AF, with coefficient of determination (R2) arround 60%. It was not obtained a good model fitting for DG (R2 = 10%).CONBE
