Effects of model calibration on hydrological and water resources management simulations under climate change in a semi-arid watershed
Semi-arid regions are known for erratic precipitation patterns with significant effects on the hydrological cycle and water resources availability. High temporal and spatial variation in precipitation causes large variability in runoff over short durations. Due to low soil water storage capacity, base flow is often missing and rivers fall dry for long periods. Because of its climatic characteristics, the semi-arid north-eastern region of Brazil is prone to droughts. To counter these, reservoirs were built to ensure water supply during dry months. This paper describes problems and solutions when calibrating and validating the eco-hydrological model SWIM for semi-arid regions on the example of the Pajeú watershed in north-eastern Brazil. The model was calibrated to river discharge data before the year 1983, with no or little effects of water management, applying a simple and an enhanced approach. Uncertainties result mainly from the meteorological data and observed river discharges. After model calibration water management was included in the simulations. Observed and simulated reservoir volumes and river discharges are compared. The calibrated and validated models were used to simulate the impacts of climate change on hydrological processes and water resources management using data of two representative concentration pathways (RCP) and five earth system models (ESM). The differences in changes in natural and managed mean discharges are negligible ( 5%) under RCP2.6 for the ESM ensemble mean. In semi-arid catchments, the enhanced approach should be preferred, because in addition to discharge, a second variable, here evapotranspiration, is considered for model validation. © 2020, The Author(s)
Relato de caso: adenocarcinoma retossigmoide com metástase para ovário esquerdo – tumor de krukenberg / Case report: retosigmoid adenocarcinoma with metastasis for left ovary - krukenberg tumor
RESUMOO tumor de krukenberg é um carcinoma metastático ovariano gastrointestinal. A apresentação é inespecífica com dor abdominal e alterações intestinais. Em média 30% das neoplasias ovarianas são metastáticas, sendo o estômago sua origem mais comum (76%), seguido do colorretal (11%). O objetivo do estudo foi relatar e revisar na literatura um caso de um paciente de 24 anos diagnosticada com Tumor de Krukenberg após investigação com exames de imagens devido à sintomatologia de dor abdominal e enterorragia, onde se identificou adenocarcinoma de reto e massa anexial esquerda. Foi realizado retossigmoidectomia com anastomose colo-anal, ileostomia em alça de proteção e salpingooforectomia esquerda. O tumor de Krukenberg tem o estômago como principal órgão de origem, seguido de retossigmóide, em baixa proporção. O prognóstico não é favorável; sendo um diagnóstico raro com possibilidade de recorrência após cirurgia citorredutora e muitas vezes seguida de terapia paliativa. Portanto, sendo o relato descrito apenas para um único ovário e sua origem retal, com dificuldade para traçar um prognóstico, torna-se relevante, o que demonstra um caso raro e de menor incidência na literatura. ABSTRACTKrukenberg's tumor is a gastrointestinal ovarian metastatic carcinoma. The presentation is nonspecific with abdominal pain and intestinal changes. On average 30% of ovarian neoplasms are metastatic, with the stomach being its most common origin (76%), followed by colorectal (11%). The aim of the study was to report and review in the literature a case of a 24-year-old patient diagnosed with Krukenberg's Tumor diagnosed after imaging studies due to symptoms of abdominal pain and enterorrhagia, which identified adenocarcinoma of the rectum and left adnexal mass. Rectosigmoidectomy was performed with a coloanal anastomosis protective loop ileostomy and left salpingoophorectomy. The Krukenberg tumor has the stomach as its main organ of origin, followed by a rectosigmoid, in a low proportion. The prognosis is not favorable; being a rare diagnosis with the possibility of recurrence after cytoreductive surgery and often followed by palliative therapy. Therefore, since the report is described only for a single ovary and its rectal origin, with difficulty in drawing a prognosis, it becomes relevant, which shows it is a rare case and of lesser incidence in the literature
MarinEye - A tool for marine monitoring
This work presents an autonomous system for marine integrated physical-chemical and biological monitoring – the MarinEye system. It comprises a set of sensors providing diverse and relevant information for oceanic environment characterization and marine biology studies. It is constituted by a physicalchemical water properties sensor suite, a water filtration and sampling system for DNA collection, a plankton imaging
system and biomass assessment acoustic system. The MarinEye system has onboard computational and
logging capabilities allowing it either for autonomous operation or for integration in other marine observing systems (such as Observatories or robotic vehicles. It was designed in order to collect integrated multi-trophic monitoring data. The validation in operational environment on 3 marine observatories: RAIA, BerlengasWatch and Cascais on the coast of Portugal is also discussed.info:eu-repo/semantics/publishedVersio

PCH: a preservação do patrimônio cultural e natural como política regional e urbana
TThis paper analyzes the roots of the Historical Cities Program (PCH), its creation in 1973, and deactivation in early 1980s. The program was rooted in the insertion of IPHAN in international cooperation network, the ideas of its articulator, Arch. Renato Soeiro, and military government objectives, which included the Northeast development through cultural tourism. The presence of northeastern and northerners people in ministries and higher ranks of the military government has contributed to its creation. After 36 years, Recife replace the leadership of Rio de Janeiro on heritage policy, strengthening local groups and setting off a struggle for control within IPHAN. Without support from the Secretariat of Planning and General Coordination of the Presidency of the Republic, the PCH started to be dismounted by the government of General João Figueiredo in 1979, after a new cultural policy to create a popular base for the "gradual and controlled opening policy." Alongside this ideological shift, the regionalist dispute between groups of Recife and Rio de Janeiro was intensified and the PCH progressively dismounted.Este texto analisa as raízes do Programa das Cidades Históricas, sua criação em 1973 e sua desativação no início da década de 1980. Suas raízes estariam na inserção do Iphan na rede de cooperação internacional, no ideário de seu principal articulador, o arquiteto Renato Soeiro, e no objetivo do governo militar de promover o desenvolvimento da região Nordeste. Para sua criação, teria contribuído a presença de nordestinos e nortistas em ministérios e altos postos do governo militar. Após 36 anos da criação do Sphan, o protagonismo das ações sobre o patrimônio seria transferido do Rio de Janeiro para o Recife, fortalecendo grupos locais e dando início a uma disputa pelo controle do Iphan. Sem contar mais com o apoio da Secretaria de Planejamento e Coordenação Geral da Presidência da República, o PCH começa a ser desativado em 1979, no governo do Gal. João Figueiredo, com uma nova política cultural destinada a criar uma base popular para a "abertura política gradual e controlada". Paralelamente a essa mudança ideológica, se acirra a disputa entre os grupos do Recife e do Rio de Janeiro e se dá a progressiva desativação do PCH
Immunogenicity and Reactogenicity of 2009 Influenza A (H1N1) Inactivated Monovalent Non-Adjuvanted Vaccine in Elderly and Immunocompromised Patients
Background\ud
\ud
Immunosuppressed individuals present serious morbidity and mortality from influenza, therefore it is important to understand the safety and immunogenicity of influenza vaccination among them.\ud
Methods\ud
\ud
This multicenter cohort study evaluated the immunogenicity and reactogenicity of an inactivated, monovalent, non-adjuvanted pandemic (H1N1) 2009 vaccine among the elderly, HIV-infected, rheumatoid arthritis (RA), cancer, kidney transplant, and juvenile idiopathic arthritis (JIA) patients. Participants were included during routine clinical visits, and vaccinated according to conventional influenza vaccination schedules. Antibody response was measured by the hemagglutination-inhibition assay, before and 21 days after vaccination.\ud
Results\ud
\ud
319 patients with cancer, 260 with RA, 256 HIV-infected, 149 elderly individuals, 85 kidney transplant recipients, and 83 with JIA were included.\ud
\ud
The proportions of seroprotection, seroconversion, and the geometric mean titer ratios postvaccination were, respectively: 37.6%, 31.8%, and 3.2 among kidney transplant recipients, 61.5%, 53.1%, and 7.5 among RA patients, 63.1%, 55.7%, and 5.7 among the elderly, 59.0%, 54.7%, and 5.9 among HIV-infected patients, 52.4%, 49.2%, and 5.3 among cancer patients, 85.5%, 78.3%, and 16.5 among JIA patients. The vaccine was well tolerated, with no reported severe adverse events.\ud
Conclusions\ud
\ud
The vaccine was safe among all groups, with an acceptable immunogenicity among the elderly and JIA patients, however new vaccination strategies should be explored to improve the immune response of immunocompromised adult patients.

A pós-graduação no Brasil, a pesquisa em educação e os estudos sobre a política educacional: os contornos da constituição de um campo acadêmico
O Programa de Cidades Históricas (PCH) no âmbito das políticas culturais dos anos 1970: cultura, planejamento e nacional desenvolvimentismo
Este artigo analisa o Programa de Cidades Históricas (PCH) como parte da rede de relações e de poder que implementou as políticas culturais nos anos 1970 no Brasil, de modo integrado ao setor econômico do governo, com base nas linhas do projeto desenvolvimentista orientadas para o regionalismo associado à descentralização. Apresenta, inicialmente, documentos oficiais que orientaram a formulação da Política Nacional de Cultura na década de 1970 e a rede de intelectuais envolvidos na sua elaboração, contemplando diferentes agências do Estado, historicamente atuantes no campo da cultura. Destaca em tais documentos a naturalização da associação entre turismo, cultura e patrimônio, via pela qual se deu a incorporação do campo da cultura nas discussões sobre o desenvolvimento socioeconômico brasileiro. Analisa as parcerias estabelecidas entre o MEC e a Secretaria de Planejamento da Presidência da República para a criação e implantação do PCH, compreendido como um projeto de ações interministeriais integradas. Busca evidenciar os modos de incorporação das políticas culturais nos planos de desenvolvimento do Brasil Grande e apontamos a complexificação das redes e das representações acerca dos valores da brasilidade associados ao tradicional popular nordestino. Foram trazidas para a análise memórias de protagonistas do alto escalão do regime militar e de técnicos que compartilharam vivências, relacionadas àquela conjuntura e ao próprio PCH, cotejadas com uma diversificada documentação.The article analyzes the Program of Historical Cities - PCH (Programa de Cidades Históricas) as part of the network of relations and power that implemented cultural policies in the 1970s in Brazil, in an integrated manner to the government's economic sector, based on the lines of development project, oriented to a regionalism associated with decentralization. It presents first official documents that guided the formulation of the National Cultural Policy in the 1970s and the intellectual network involved in its preparation, comprising officers from different state agencies, historically active in the cultural field. The article highlights the naturalization of the association between tourism, culture and heritage and the inclusion of the cultural field in the discussions about the Brazilian socioeconomic development. It analyzes partnerships between the Ministry of Education and Culture and the Secretariat of Planning of the Presidence of the Republic (Secretaria de Planejamento da Presidência da República) for the creation and implementation of the PCH, understood as a project of integrated ministerial actions. We identify the ways of incorporation of cultural policies in development plans of the ideological program called "Great Brasil" (Brasil Grande), and pointed out the complexity of networks and representations about the Brazilianness values associated with the traditional folk Northeastern. We brought for analysis the memories of high-ranking military regime protagonists and technicians who shared experiences related to the PCH, and collated them with a diverse documentation
