O objetivo geral foi o de desenvolver um equipamento que é utilizado como carregador de aparelho celular solar, ar um custo x benefício viável, em comparação ao carregador elétrico. Como metodologia foi adotada a pesquisa de revisão bibliográfica e aplicada. Os resultados indicam que o equipamento é prático, funciona, e seu custo é bem inferior ao custo de equipamentos similares disponíveis no mercado. Por isso, concluiu-se que é viável.

Dessa forma, o problema deste estudo é verificar se os bancos que compõe o sistema financeiro brasileiro praticaram income smoothing entre o período de 2011 até o segundo semestre de 2017, período esse, de desaceleração da economia brasileira e que culminou em uma recessão econômica.Método: Adotou-se a regressão logit em painel com efeitos aleatórios. A suavização de resultado foi medida pelo índice de Eckel (1981) e sua relação foi testada com os cenários econômicos do Brasil e de diferentes economias globais.Resultados: Este estudo identifico...

This cross-sectional analytical study included 127 nurses of critical units of an university hospital. We used structured interview with 12 questions to evaluate their knowledge about the scale. Association of Knowledge with professionals' sociodemographic variables were verified by the Fisher-test, χ2 and likelihood ratio. Most of participants were women mean aged 31.1 years, they had graduated more than 5 years previously, and had 1 to 3 years of work experience. In the assessment of best score possible for Glasgow scale (question 3) nurses who had graduate more than 5 years ago presented a lower percentage success rate (p=0.0476). However, in the question 7, which evaluated what interval of the scale indicated moderate severity of brain trauma injury, those with more years of experience had higher percentage of correct answers (p=0.0251). In addition, nurses from emergency s...

In Brazil the North, Northeast, Midwest and Southeast are endemic, infecting various mammals, including domestic cats through the bite of female mosquitoes of the genus Lutzomyia, which presents great adaptation to the urban environment. Elucidate the epidemiology of the disease has been the aim of several studies because it has varied behaviors as characteristics of area and population. Although, cats are abble to be infected and direct contact with humans, their role in the epidemiology of leishmaniasis is still unclear, since these animals may be asymptomatic or have a disease associated with others diseases which cause immunosuppression, in addition they may have a natural resistance. The cutaneous form is the most reported in cats and they can presente uveitis, lymphadenopathy local or general, emesis, diarrhea, dehydration, stomatitis and anorexia. The diagnosis can be clinical, parasitological, immunological and molecular. The treatment is described in a few cases, with clinical reports ranging from complete success until euthanasia. Despite the existence of some studies investigating the prevalence of infection in populations of cats living in endemic areas, it is not clear if the low prevalence of infection and disease in cats from endemic areas, are due to failures in detecting antibodies or the fact of cats present natural resistance to leishmaniasis.

Their structures were elucidated on the basis of spectroscopic analysis (IR, 1D and 2D NMR, ESI-MS) and by comparison with authentic samples. New compounds 6 and 10, together with some of the known compounds, had their antitumor (cytotoxic), antifungal and allelopathic activities evaluated. Phenanthrene 10 was active against three cancer cell lines, with IC50 between 5 and 8 μg/mL and against four Candida species, presenting higher activity than fluconazol against Candida tropicalis; compound 10 also showed good allelopathic activity on germination of Lactucca sativa, and on shoot and radicle growth of Allium cepa. Phenanthrene 6 presented good allelopathic activity in most evaluations made.
