Sinais caseiros: análise de pesquisas indexadas no catálogo de teses e dissertações da Capes (Homemade signs: analysis of research indexed in Capes' theses and dissertations catalog)
This work is part of a larger research, which investigates language status in 'homemade signs'. This is a review of previous research, considering the relevance of knowing the works developed in the area, the phenomena focused on and what aspect still need to be studied. We aimed to inventory and to analyze the dissertations and theses, which address 'homemade signs', found primarily in the Capes database, from the period between 2003 and 2019. To do so, we opted for bibliographical research of the 'state of the art' type, which has the purpose of mapping a certain academic production. As a result, we found 11 researches, among which 18,18% present analyses on 'homemade signs', and the rest investigate indigenous signs. We found, from the data, that, despite the great contribution of these studies in the academic scenario, regarding the linguistic nature of the 'homemade sign' systems, this is still discussed in an incipient way, which corroborates the need for further investigation.Este trabajo forma parte de una investigación más amplia que aborda el status de lengua en señas caseras. Se trata de una revisión de investigaciones anteriores, considerándose la relevancia de conocer los trabajos desarrollados en el área, los fenómenos discutidos y qué aspectos todavía carecen de estudios. Pretendemos inventariar y analizar las tesis de doctorado y maestría que tratan de “señas caseras”, constantes prioritariamente en la base de datos de la Capes, del período entre el 2003 y el 2019. Para ello, hemos optado por la búsqueda bibliográfica del tipo “estado del arte”, que tiene como propósito mapear cierta producción académica. Como resultado, hemos encontrado once investigaciones, entre las cuales el 18,18% presentan análisis sobre “señas caseras”; las demás abordan las “señas indígenas”. A partir de los datos, hemos constatado que, a pesar de la gran contribución de esos estudios en el escenario académico, la naturaleza lingüística de los sistemas de “señas caseras” se discute todavía de modo incipiente, lo cual corrobora la necesidad de más investigación.Este trabalho faz parte de uma pesquisa mais ampla, que investiga o status de língua em 'sinais caseiros'.

Sleep and sex sleep in adolescence : sex matters?
© 2019 All rights reservedObjective: Sleep is of upmost importance for everybody and especially for adolescents who face life and leisure challenges that may impair their sleep. This study aimed to verify if girls are at a higher risk to present sleep problems and if associations of a sleep perception are different between sexes even when accounting for biological maturation. Methods: Data is from the HBSC Portuguese survey 2014, all variables were self-reported. Participants were 3869 adolescents (2057 girls), mean age 14.8 years. Participants’ socio-demographic characteristics included sex, age, school grade, father and mother education; besides participants were inquired about sleep duration and characteristics of their sleep quality. Results: Sleep deprivation was reported by 13.1% of the adolescents (girls 14.3%, boys 11.7%, p<0.05). The most prevalent characteristics of poor sleep quality were waking up tired (50.8%) and difficulties falling asleep (19.5%), for both girls presented higher prevalence than boys. Overall, girls presented a poorer sleep health with low quality and quantity of sleep. Furthermore, associations of an enough and good sleep were different between boys and girls, even when controlling for the impact of delayed pubertal maturity. Discussion: Together with screen time, substance use, poorer nutrition, sedentary behaviours and abuse of screen time, sleep is an issue that must be addressed by professionals, families and public policies with impact in family life and family routines. Modelling a health education in schools should include the sleep topic. In addition, yes, sex matters and must be included on board.info:eu-repo/semantics/publishedVersio
Impactos causados no meio ambiente por resíduos antimicrobianos de uso veterinário: Impacts caused on the environment use antimicrobial waste
O uso de antimicrobianos em propriedades de produção tem se tornado muito frequentes, uma vez que são de fácil acesso e baixo custo, no entanto, seu uso indiscriminado acaba gerando grandes perdas e prejuízos econômicos, além de problemas relacionados à conservação da saúde.
O objetivo da revisão de literatura proposta é apresentar quais os impactos causados por esses fármacos no meio ambiente e nos seres que nele vivem, além de expor alternativas para a substituição ao uso de antimicrobianos, no intuito de minimizar problemas de interesse em saúde pública.
Para tanto, a mesma tem como base de pesquisa, estudos científicos evidenciando suas consequências em decorrência da resistência gerada por antimicrobianos, e aponta opções como fitogênicos, vacinação, o uso de prebióticos e probióticos a fim de reduzir a contaminação do meio ambiente por meio de resíduos
Citizen science for public deliberation of local environment policies
Broadening citizen participation in scientific knowledge production has become a priority of national and supra-national institutions and research agencies. Out of their interest for scientific research and public learning, citizen science projects are often presented as offering a unique opportunity to involve more directly the public in policy-making. However, despite twenty years of flourishment of participative scientific research, making citizen science a tool to foster participatory democracy remains a challenge. Political outputs of citizen science are indeed often restricted to its role in the production of data to inform policy making processes. In this paper, we propose an innovative theoretical model of democratization through citizen science, in which participative data collection is associated with public online deliberation. Drawing both on online political deliberation research and citizen science literature, we argue that citizens’ engagement in contributory science could help create the conditions of good-quality public deliberations. We then present a technical device (an online platform) that put this model into practice in the context of the regulation of public lighting in two French municipalities
Interdisciplinaridade Decolonial no Espaço Não Formal: Saberes dos Ferreiros Africanos Usados Durante a História da Humanidade
O presente texto é resultado de uma reflexão levantada após uma aula de campo, que englobou diversas áreas do saber, com o fito de destacar os saberes científicos feitos por outros povos, que não o branco europeu/colonizador. Em outras palavras, uma decolonização do ensino das ciências, à qual é marcada pela valorização das contribuições, saberes, técnicas empregadas por povos tradicionais e africanos. A aula interdisciplinar (História e Química) em questão tratou-se de uma aula de campo ao Museu Náutico da Bahia, entre estudantes da 2ª série do Colégio Estadual Assis Chateaubriand, no município de Salvador, Bahia, Brasil. Nela, os estudantes puderam ter acesso não só a um monumento histórico, como também ao “tocar” no passado e notar que em especial os africanos escravizados, traziam consigo também, conhecimentos e tecnologias. Dentre os saberes resgatados nas Ciências, destacamos para este trabalho o conhecimento da metalurgia do ferro na África Ocidental, que influenciou sobremaneira as relações sociais e econômicas dessa população na diáspora e em sua terra natal – dos ofícios (ferreiros, mineiros) aos rituais e usos desse metal nas mais diversas áreas. O processo de fundição trouxe às civilizações avanços técnicos e práticos, instrumentalizando o homem em suas atividades cotidianas – das domésticas às laborais –, como também no que se refere ao uso bélico, haja vista a confecção de armas brancas e de fogo – canhões – e o comércio que se articulou entre os tempos e os continentes. As aulas e atividades foram realizadas sob o prisma afrocentrado.: This text is the result of a reflection raised after a field class, which encompassed several areas of knowledge. In order to highlight the scientific knowledge made by other peoples, other than the European white / colonizer; in other words, a decolonization of science education marked by disregard for contributions, knowledge, techniques employed by traditional peoples, and Africans. The interdisciplinary class (History and Chemistry) in question was a field class at the Nautical Museum of Bahia, among 2nd year students at Colégio Estadual Assis Chateaubriand, in the city of Salvador, Bahia, Brazil. In it, the students were able to have access not only to a historical monument, but also to “touch” the past and notice that especially the enslaved Africans also brought with them knowledge and technologies. Among the knowledge recovered in Sciences, we highlight for this work the knowledge of iron metallurgy in West Africa, which greatly influenced the social and economic relations of this population in the diaspora and in their homeland - from crafts (blacksmiths, miners) to rituals and uses of this metal in the most diverse areas. The foundry process brought technical and practical advances to civilizations, instrumentalizing man in his daily activities - from domestic to work -, as well as with regard to war use, given the manufacture of white weapons and firearms - cannons - and the trade that was articulated between the times and the continents
Avaliação cefalométrica dos resultados do aparelho de protração mandibular (APM) associado ao aparelho fixo em relação às estruturas dentoalveolares e tegumentares em pacientes portadores de má oclusão de classe II, 1a. divisão
Objective: To perform a cephalometric evaluation of dentoalveolar and soft tissue changes in Brazilian youths with Class II, division 1 malocclusion, treated with a mandibular protraction appliance (MPA) combined with fixed corrective orthodontics. Methods: The sample consisted of 28 patients (16 females and 12 males) with a mean age of 13.06 years, treated for a mean period of 14.43 months. The changes were measured on 56 specific cephalometric analysis obtained from lateral cephalograms taken before and after treatment by two calibrated examiners in order to identify soft tissue and dentoalveolar changes using linear and angular cephalometric measures. The independent variables sex, age, facial pattern, MPA model, archwire, technique and treatment time were registered and analyzed using linear and angular cephalometric measures. Treatment responses were analyzed and compared by the Wilcoxon Signed Ranks and Mann-Whitney tests at a significance level of 5%. Results: The results showed dentoalveolar changes of great
magnitude, which caused positive changes in soft tissue. It was also noted that the variables age, MPA model and technique influenced the treatment. Conclusions: MPA proved to be an effective alternative in the treatment of Class II, division 1 malocclusion, inducing dentoalveolar and soft tissue changes with satisfactory clinical results
Estudo de viabilidade técnica e econômica para aplicação de organic photovoltaics (OPV) em um edifício residencial / Technical and economic viability study for organic photovoltaics (OPV) for application in a residential building
O OPV (Organic Photovoltaics) é recomendado para locais onde não se possa instalar placas solares, como claraboias de shoppings ou fachadas de prédios. Este produto é desenvolvido e comercializado no Brasil e no mundo pela startup mineira (SUNEW), que vem se destacando como uma excelente alternativa de geração de energia elétrica. Quanto à metodologia, este estudo pode ser classificado como qualitativo, quantitativo e descritivo e para tal foi utilizado como referência um edifício residencial de médio porte. Ademais, foram analisados a utilização atual do local e paralelo a coleta de dados, quantificou-se o investimento inicial e o ganho ambiental por redução na emissão de carbono. Conclui-se que, os resultados obtidos foram satisfatórios por ser um produto novo no mercado. Entretanto, sua implantação requer um investimento elevado, o que inviabiliza sua aplicação em pequenos projetos, sendo direcionado a um público que visa produtos sustentáveis, e empresas que se apoiam no marketing verde para atingir esse nicho específico.
Environmental Diagnosis of Permanent Preservation Areas (APP) of the Capibaribe River in the city of Recife – PE
The Permanent Preservation Areas (APP) is critical in the preservation of water resources, highlighting the quality of waterways and maintenance of its volume. However, urban sprawl and the lack of public policies produce undesirable consequences for the population of the deforested region and for the part of the basin that is fed by these waters. In this context, this study aimed to analyze the environmental impacts that enhance the degradation of the river Capibaribe APP, located in Recife. They were predetermined two points (Joana Bezerra and rabbits neighborhood) in which it identified the on-site impact and made a qualitative analysis of areas. It was observed that the chosen points are with APP well below what is determined by the existing laws, in most cases, they are the result of human activities. The release of solid waste and organic matter in these areas leverage the APP degradation, directly affecting the physical and biological characteristics of rivers. Thus, the implementation of awareness programs is critical to population and also an effective surveillance system to combat the impact of permanent preservation areas
Cálculo da evolução temporal de área degradada às margens do rio Tapacurá na Zona da Mata de Pernambuco, Brasil
Atualmente, no município de Vitória de Santo Antão em Pernambuco, ocorre um crescimento econômico por causa dos investimentos na área industrial, com elevação da população urbana e decréscimo da população rural. A combinação de ações impactantes para o meio ambiente quanto a redução dos recursos naturais em função da ação de impactos antrópicos negativos, gerando a degradação ambiental, em muitos casos, ocorre devido a despreocupação humana com a sobrevivência das futuras gerações por conta das necessidades atuais de infraestrutura urbana. O objetivo deste estudou consistiu na identificação da degradação ambiental por ações antrópicas em área urbana as margens do rio Tapacurá no município de Vitória de Santo Antão-PE, utilizando técnicas de geoprocessamento de dados em área delimitada. Com o auxílio do Google Earth Pro foram analisadas as áreas vegetadas nos mapas nos meses de julho de 2006, junho de 2011 e novembro de 2015. A área estudada foi considerada degradada após avaliação visual local, através de construções irregulares, ocorrendo a incidência de aterro com resíduos de construção e disposição incorreta de resíduos sólidos, o que provocou danos a vegetação em especial nas matas ciliares as margens do rio, com resultados de área vegetada em evolução decrescente nos anos 2006, 2011 e 2015, respectivamente de 61,65%, 40,30% e 13,49%, totalizando 86,51% de degradação da área de estudo, o que prejudica o escoamento de água em períodos de altas precipitações, gerando camadas impermeáveis em áreas de vales, o que o causa vulnerabilidade as áreas urbanas a riscos de inundações
POLLUTION MITIGATION FOR HYDROCARBONS OF PETROLEUM THROUGH THE BIOREMEDIATION
Environmental contamination by hydrocarbons resulting from activities related to the oil sector is one of the great problems of our time and with the growth of production, distribution and consumption in recent years accidents involving oil or its derivatives have been increasingly steady. This environmental problems and frequent have become increasingly critical, since as can reach the soil, air and bodies of surface and underground water. Besides that, contain compounds with high level of toxicity, mobility and persistence in the environment, and generate a major ecological impact, these pollutants hinder the treatment of contaminated areas. The objective this work is to analyze from the law involved in the prevention of environmental damage this work also sought to introduce control measures and repair of the impacts caused by the oil industry, with emphasis on bioremediation technology as a mitigation measure, working in the recovery of degraded areas. Several studies developed in Brazil and the world has shown good results in restoring environments that have been polluted by hydrocarbons. It was also demonstrated the importance of the choice of technique bioremediation that followed the most used techniques for the biodegradation of hydrocarbons, both in situ and ex situ, as well as the processes involved for the bioremediation occurs effectively and safely. The development of studies like this can help generate new technologies or improve those that already exist, which is fundamental for the enrichment of new environmental decontamination projects.Environmental contamination by hydrocarbons resulting from activities related to the oil sector is one of the great problems of our time and with the growth of production, distribution and consumption in recent years accidents involving oil or its derivatives have been increasingly steady.
