Candida albicans is an opportunistic yeast and a member of the normal human flora that commonly causes infections in patients with any type of deficiency of the immune system. The essential oils have been tested for antimycotic activity and pose much potential as antifungal agents. This work investigated the activity of the essential oil of Cymbopogon winterianus against C. albicans by MIC, MFC and time-kill methods. The essential oil (EO) was obtained by hydrodistillation using a Clevenger-type apparatus. It was tested fifteen strains of C. albicans. The MIC was determined by the microdilution method and the MFC was determined when an aliquot of the broth microdilution was cultivated in SDA medium. The phytochemical analysis of EO showed presence of citronellal (23,59%), geraniol (18,81%) and citronellol (11,74%). The EO showed antifungal activity, and the concentrations 625 µg/mL and 1250 µg/mL inhibited the growth of all strains tested and it was fungicidal, respectively. The antimicrobial activity of various concentrations of EO was analyzed over time, it was found concentration-dependent antifungal activity, whose behavior was similar to amphotericin B and nystatin.
In this paper we consider the generalized uncertainty principle in the tunneling formalism via Hamilton-Jacobi method to determine the quantum-corrected Hawking temperature and entropy for 2+1-dimensional noncommutative acoustic black holes. In our results we obtain an area entropy, a correction logarithmic in leading order, a correction term in subleading order proportional to the radiation temperature associated with the noncommutative acoustic black holes and an extra term that depends on a conserved charge. Thus, as in the gravitational case, there is no need to introduce the ultraviolet cut-off and divergences are eliminated.
In this paper we explore the effect of the generalized uncertainty principle and modified dispersion relation to compute Hawking radiation from a rotating acoustic black hole in the tunneling formalism by using the Wentzel-Kramers-Brillouin (WKB) approximation applied to the Hamilton-Jacobi method. The starting point is to consider the planar acoustic black hole metric found in a Lorentzviolating Abelian Higgs model. In our analyzes we investigate quantum corrections for the Hawking temperature and entropy. A logarithmic correction and an extra term that depends on a conserved charge were obtained. We also have found that the changing in the Hawking temperature TH for a dispersive medium due to a Lorentz-violating background accounts for supersonic velocities in the general form (vg − vp)/vp = ∆TH /TH
<p><strong>Objetivo</strong>: Este trabalho buscou revisar aspectos da relação entre Sustentabilidade e Ciências da Saúde, a partir da abordagem de áreas das instituições hospitalares que são permeadas pelo Desenvolvimento Sustentável. <strong>Material e Método:</strong> Trata-se de uma pesquisa exploratória, de natureza quantitativa, delineada como Bibliográfica. <strong>Resultados e Discussão:</strong> Foram abordados os determinantes sociais do processo saúde-doença, a gestão de resíduos sólidos, práticas de gestão sustentáveis e as nuances ambientais na arquitetura e infraestrutura hospitalar. No estudo da relação entre Saúde e Meio Ambiente, nota-se uma relação intrínseca da degradação ambiental como determinante do padrão epidemiológico de emergência e reemergência das doenças. Quanto à questão dos resíduos sólidos, constatou-se que o arcabouço jurídico, administrativo já é suficiente à solução da problemática, contudo, falta efetivação e fiscalização. As práticas sustentáveis na área da gestão, que se relacionam principalmente com o pilar econômico do desenvolvimento sustentável, também impactam na sustentabilidade ambiental, pois, a melhoria da gestão dos recursos reduz a compra de excedentes e a produção de resíduos. O apelo para adoção de práticas sustentáveis também vem ganhando espaço na arquitetura hospitalar, avançando na preocupação com o impacto ambiental do prédio. <strong>Conclusão</strong>: Mesmo que inicialmente restrita às noções de determinação ambiental do processo saúde-doença, a Sustentabilidade vem ganhando espaço nos campos administrativos, de infraestrutura, de gestão de recursos, que por se moldarem às necessidades particulares do setor Saúde tornam-se estratégicos para a adoção de práticas baseadas no Desenvolvimento Sustentável.</p><p> </p>
