Sistema de Informação Geográfica na Internet para apoio à gestão de Infra-estruturas, baseado em ferramentas Open Source

A gestão de infra-estruturas é um processo de coordenação, avaliação sistemática e manutenção efectiva das infra-estruturas relacionadas com os serviços básicos. A gestão eficaz de infra-estruturas exige que a disposição dos equipamentos no meio urbano seja conhecida, bem como sua relação com o uso do solo. Sendo a gestão de infra-estruturas uma questão de natureza espacial, é natural pensar na utilização de um Sistema de Informação Geográfica como ferramenta com potencial de grande utilidade, pois permite a georreferenciação de dados espaciais e sua interligação com atributos alfanuméricos, para além da realização de análises complexas e a possibilidade de simular diversos cenários de modo a propiciar uma tomada de decisão eficaz. O elevado custo das licenças e a especificidade de utilização a nível técnico, tornam-se obstáculos na criação e manutenção de dados geográficos. Contudo os recentes desenvolvimentos em tecnologias da Internet têm contribuído para o acesso, publicação, exploração e distribuição da Informação Geográfica. A utilização de SIG distribuídos na Internet (WebGIS), nomeadamente na vertente livre, pode ser uma solução adequada visto que coloca funcionalidades de SIG ao alcance de utilizadores, através de um simples browser, sem necessidade de investimentos em relação a software ou mesmo em formação técnica especializada. Assim, com este projecto pretende-se a criação de um sistema de Informação geográfico na Internet, utilizando softwares livres, que disponibiliza toda a informação geográfica e alfanumérica das infra-estruturas construídas e sob a responsabilidade do Ministério das Infra-estruturas e Economia Marítima, permitindo a visualização e a realização de pesquisas e operações de análise.

Activities of tabanids (Diptera, Tabanidae) attacking domestic duck-Cairina moschata (Linnaeus) (Aves, Anatidae), introduced in a forest area in the Central Amazon, Manaus, Brazil

Presented here are the feeding habits, attack behavior, daily and annual activity of adult of Phorcotabanus cinereus (Wiedeman, 1821), Chrysops laetus (Fabricius, 1805) and Phaeotabanus cajennensis (Fabricius, 1787), while biting a domestic duck, Cairina moschata (Linnaeus, 1758). The last two species were recorded for the first time attacking birds. This study comprehended monthly observations of two consecutive days from April/97 to March/98 between 5:30 a.m. and 6:30 p.m. at the Army Instructional Base ((BI-2/CIGS) near Manaus. Annual occurrence of P. cinereus was from July to September, with a daily occurrence between 9:00 a.m. and 5:00 p.m. and highest activity at 12:00 a.m. and 2:00 p.m. C. laetus ocurred from June to October; with a daily occurrence between 8:00 a.m. and 3 p.m. and highest activity at 11:00 and 12:00 a.m. Occurrence of P. cajennensis with one specimen only, was in July between 10:00 and 11:00 a.m.

A U-shaped association between intensity of Internet use and adolescent health.

OBJECTIVE: To examine the relationship between different Internet-use intensities and adolescent mental and somatic health. METHODS: Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health, a nationally representative survey of adolescents aged 16 to 20 years in post-mandatory school. From a self-administered anonymous questionnaire, 3906 adolescent boys and 3305 girls were categorized into 4 groups according to their intensity of Internet use: heavy Internet users (HIUs; >2 hours/day), regular Internet users (RIUs; several days per week and <= 2 hours/day), occasional users (<= 1 hour/week), and non-Internet users (NIUs; no use in the previous month). Health factors examined were perceived health, depression, overweight, headaches and back pain, and insufficient sleep. RESULTS: In controlled multivariate analysis, using RIUs as a reference, HIUs of both genders were more likely to report higher depressive scores, whereas only male users were found at increased risk of overweight and female users at increased risk of insufficient sleep. Male NIUs and female NIUs and occasional users also were found at increased risk of higher depressive scores. Back-pain complaints were found predominantly among male NIUs. CONCLUSIONS: Our study provides evidence of a U-shaped relationship between intensity of Internet use and poorer mental health of adolescents. In addition, HIUs were confirmed at increased risk for somatic health problems. Thus, health professionals should be on the alert when caring for adolescents who report either heavy Internet use or very little/none. Also, they should consider regular Internet use as a normative behavior without major health consequence. Pediatrics 2011;127:e330-e335

O Uso da Internet como Ferramenta de Comunicação na Promoção dos Destinos Turistícos: O caso da Ilha do Maio.

O presente trabalho procura conhecer “até que ponto a internet pode ser uma ferramenta de comunicação, estratégica na promoção da ilha do Maio como destino turístico”. Para isso formulou-se inicialmente a seguinte pergunta de partida: de que forma a internet pode contribuir na promoção da ilha do Maio como destino turístico? Para responder a pergunta de partida foram analisados documentos para a fundamentação teórica tais como estudos efectuados por LAVAREDAS (2010), LOPES (2005), MARUJO (2004), MIRANDA (2005). No que diz respeito aos aspectos metodológicos foi utilizado a abordagem quanti-qualitativa que é a melhor que se adapta a este estudo, é um estudo exploratório, descritivo e explicativo. Para o estudo de caso os sujeitos da pesquisa foram os turistas, os profissionais de comunicação e o presidente da câmara municipal do Maio. Com os resultados da pesquisa de campo concluiu-se que a internet constitui uma ferramenta estratégica para a divulgação da ilha do Maio como destino turístico no entanto ainda quase não se verifica a sua utilização.

Twitch and M-wave potentiation induced by intermittent maximal voluntary quadriceps contractions: Differences between direct quadriceps and femoral nerve stimulation.

Introduction: To investigate differences in twitch and M-wave potentiation in the quadriceps femoris when electrical stimulation is applied over the quadriceps muscle belly versus the femoral nerve trunk. Methods: M-waves and mechanical twitches were evoked using direct quadriceps muscle and femoral nerve stimulation between 48 successive isometric maximal voluntary contractions (MVC) from 10 young, healthy subjects. Potentiation was investigated by analyzing the changes in M-wave amplitude recorded from the vastus medialis (VM) and vastus lateralis (VL) muscles and in quadriceps peak twitch force. Results: Potentiation of twitch, VM M-wave, and VL M-wave were greater for femoral nerve than for direct quadriceps stimulation (P<0.05). Despite a 50% decrease in MVC force, the amplitude of the M-waves increased significantly during exercise. Conclusions: In addition to enhanced electrogenic Na(+) -K(+) pumping, other factors (such as synchronization in activation of muscle fibers and muscle architectural properties) might significantly influence the magnitude of M-wave enlargement. © 2013 Wiley Periodicals, Inc.

A new species of the genus Pimelerodius Vanin from the Amazon Region, with notes on the geografic distribution of Pimelerodius motacilla (Boheman) (Coleoptera, Curculionidae, Otidocephalini)

Pimelerodius punctiventris sp. nov. (type locality Brazil, Amazonas, Itacoatiara) is described and illustrated. The new taxon is compared with similar species, being distinguished from the other 12 known species of the genus by the presence of punctures in ventrite I. The available published key for identification of species of Pimelerodius is adapted to include the new species. A modification of the generic description of the aedeagus of Pimelerodius is provided, a necessity due to the differences observed in the aedeagus of the new species. The occurrence of P. motacilla (Boheman, 1843) in the Amazon Region, recorded in sympatry with P. punctiventris in Itacoatiara, AM, is discussed and confirmed, based on the study of 41 available specimens.

A synopsis of the Hydrometra (Hemiptera, Heteroptera, Hydrometridae) from the Amazon River floodplain, Brazil, with redescription of Hydrometra argentina Berg

Hydrometra argentina Berg, 1879, H. caraiba Guérin-Méneville, 1857 and H. guianana Hungerford & Evans, 1934 are newly recorded in the Amazon River floodplain, Brazil. A redescription of H. argentina is also given, as the original description is incomplete. A key to the three known species occurring in this region is provided. Hydrometra argentina can be distinguished from H. caraiba and H. guianana by the body length smaller than 12.50 mm, anteoculus/postoculus ratio between 1.80 and 2.00, clypeus narrow and conical, metacetabulum with no circular pits, and projections on male abdominal sternite VI in the shape of simple spines. The other species can be distinguished mainly by the anteoculus/postoculus ratio and position of projections on male abdominal sternite VI.

Internet use by patients with psychiatric disorders in search for general and medical informations

BACKGROUND: Internet is commonly used by the general population, notably for health information-seeking. There has been little research into its use by patients treated for a psychiatric disorder. AIM: To evaluate the use of internet by patients with psychiatric disorders in searching for general and medical information. METHODS: In 2007, 319 patients followed in a university hospital psychiatric out-patient clinic, completed a 28-items self-administered questionnaire. RESULTS: Two hundred patients surveyed were internet users. Most of them (68.5%) used internet in order to find health-related information. Only a small part of the patients knew and used criteria reflecting the quality of contents of the websites consulted. Knowledge of English and private Internet access were the factors significantly associated with the search of information on health on Internet. CONCLUSIONS: Internet is currently used by patients treated for psychiatric disorders, especially for medical seeking information.
