Journal of Building Construction and Planning Research (JBCPR) , 2017, DOI: 10.4236/jbcpr.2017.52004
Abstract: Urban populations today are exposed to high levels of noise, which may cause discomfort and lead to health problems. Most of these noises are traffic-generated; therefore, this study focuses on evaluating the soundscapes of urban open spaces to determine its importance for the health of the citizen, since such spaces can function as noise attenuators. The methodology of this study involved a literature review, computer simulations and interviews with users of the aforementioned open spaces. The case study was conducted in an urban area in the city of Vitória, state of Espírito Santo, Brazil. The results indicate that, in the period of this study, traffic noise dissipated through open spaces but noise levels still exceeded the maximum allowable levels established by regulations. Nevertheless, the population proved to be largely unaware of the noise. It should be pointed out that the areas under study are used predominantly as recreational spaces for health and wellbeing activities. The findings of this study may serve to underpin urban planning policies that encourage the inclusion of open spaces, especially in areas of high urban density where the transport system consists of motor vehicles, in order to help control urban noise.

Revista Ciência em Extens?o , 2010,
Abstract: Introdu o: O laboratório iniciou suas atividades em 2001, oferecendo, diretamente para clientes particulares ou através da Justi a, exames de filia o pela análise do DNA. A partir de 2002, este passou a realizar análises de identifica o humana em vestígios biológicos para finalidade forense e, em 2003, come ou a desenvolver pesquisas na área de identifica o humana. Em 2006, foi estabelecida uma parceria com o IMESC (Instituto de Medicina Social e de Criminologia de S o Paulo) via Secretaria da Saúde de Araraquara, ficando o laboratório responsável por coletar material biológico para exame de DNA em mais de 17 municípios. Objetivos: Oferecer à comunidade testes laboratoriais de qualidade que possam ser utilizados para fornecer evidências objetivas, imparciais e definitivas quanto à identidade humana e, através das pesquisas, obter dados genético-populacionais da popula o brasileira, ainda insuficientes. Métodos: Nos casos de investiga o de paternidade, foram analisados amostras sanguíneas de casos trio (m e, filho e suposto pai), duo (filho e suposto pai) e reconstru es (suposto pai ausente), nos casos forenses, foram estudados vestígios biológicos (tais como, ossos, dentes e diferentes tecidos) e amostras-referência (sangue de supostos familiares da vítima). Para a genotipagem dos DNAs, extraídos por diferentes técnicas, foi utilizada a rea o em cadeia de polimerase e corrida eletroforética em seqüenciador automático. Foram produzidos perfis genéticos que, quando comparados, permitiram afirmar a existência ou n o de vínculo biológico entre as amostras, calculando-se a probabilidade estatística de tal evidência. No campo da pesquisa, têm sido estudados marcadores genéticos autoss micos, dos cromossomos sexuais (X/Y) e DNA mitocondrial na popula o brasileira. Resultados: Até o início do decorrente ano, 500 famílias (IMESC) foram atendidas e 08 perícias forenses e 127 (113 trios, 9 duo e 5 reconstru es) investiga es de paternidade foram realizadas, sendo que todo o trabalho é realizado com a colabora o do grupo discente, sob a coordena o das Professoras R.M.B. Cicarelli e V.L.S. Alvarenga. Todas as análises forenses consistiram de exames particulares, as de paternidade, 66% foram particulares e 34% judiciais. Os resultados obtidos se subdividiram em inclus o (63%), exclus o (35,5%) e inconclusivo (1,5%), sendo este último relacionado às perícias criminais. Foram orientados 4 inicia es científicas (1 em andamento), 2 mestrados (1 em andamento) e 1 doutorado (em andamento). Quatro trabalhos já foram publicados, gerando informa es importantes s
The local Calderon problem and the determination at the boundary of the conductivity
Giovanni Alessandrini,Romina Gaburro
Mathematics , 2008, DOI: 10.1080/03605300903017397
Abstract: We discuss the inverse problem of determining the, possibly anisotropic, conductivity of a body $\Omega\subset\mathbb{R}^{n}$ when the so--called Dirichlet-to-Neumann map is locally given on a non empty portion $\Gamma$ of the boundary $\partial\Omega$. We extend results of uniqueness and stability at the boundary, obtained by the same authors in SIAM J. Math. Anal. 33 (2001), no. 1, 153--171, where the Dirichlet-to-Neumann map was given on all of $\partial\Omega$ instead. We also obtain a pointwise stability result at the boundary among the class of conductivities which are continuous at some point $y\in\Gamma$. Our arguments also apply when the local Neumann-to-Dirichlet map is available.
Lipschitz stability for the inverse conductivity problem for a conformal class of anisotropic conductivities
Romina Gaburro,Eva Sincich
Mathematics , 2014, DOI: 10.1088/0266-5611/31/1/015008
Abstract: We consider the stability issue of the inverse conductivity problem for a conformal class of anisotropic conductivities in terms of the local Dirichlet-to-Neumann map. We extend here the stability result obtained by Alessandrini and Vessella in Advances in Applied Mathematics 35:207-241, where the authors considered the piecewise constant isotropic case.

Physics , 2003, DOI: 10.1063/1.1757025
Abstract: The electrical conductance of porous silicon fabricated with heavily doped p-type silicon is very sensitive to NO$_2$. A concentration of 10 ppb can be detected by monitoring the current injection at fixed voltage. However, we show that the sign of the injection variations depends on the porous layer thickness. If the thickness is sufficiently low -- of the order of few \micro\meter{} -- the injection decreases instead of increasing. We discuss the effect in terms of an already proposed twofold action of NO$_2$, according to which the free carrier density increases, and simultaneously the energy bands are bent at the porous silicon surface.

Mathematics , 2015,
Abstract: We consider the electrostatic inverse boundary value problem also known as electrical impedance tomography (EIT) for the case where the conductivity is a piecewise linear function on a domain $\Omega\subset\mathbb{R}^n$ and we show that a Lipschitz stability estimate for the conductivity in terms of the local Dirichlet-to-Neumann map holds true.

Abstract: The propensity to develop an anxiety disorder is thought to be determined by genetic and environmental factors. Here we investigated the relationship between a genetic predisposition to trait anxiety and experience-based learned fear in a psychopathological mouse model. Male CD-1 mice selectively bred for either high (HAB), or normal (NAB) anxiety-related behaviour on the elevated plus maze were subjected to classical fear conditioning. During conditioning both mouse lines showed increased fear responses as assessed by freezing behaviour. However, 24 h later, HAB mice displayed more pronounced conditioned responses to both a contextual or cued stimulus when compared with NAB mice. Interestingly, 6 h and already 1 h after fear conditioning, freezing levels were high in HAB mice but not in NAB mice. These results suggest that trait anxiety determines stronger fear memory and/or a weaker ability to inhibit fear responses in the HAB line. The enhanced fear response of HAB mice was attenuated by treatment with either the α2,3,5-subunit selective benzodiazepine partial agonist L-838,417, corticosterone or the selective neurokinin-1 receptor antagonist L-822,429. Overall, the HAB mouse line may represent an interesting model (i) for identifying biological factors underlying misguided conditioned fear responses and (ii) for studying novel anxiolytic pharmacotherapies for patients with fear-associated disorders, including post-traumatic stress disorder and phobias.
Multiparametric Porous Silicon Sensors

Sensors , 2002, DOI: 10.3390/s20300121
Abstract: We investigated the possibility of using several sensing parameters from porous silicon in order to improve gas selectivity. By fabricating porous silicon optical microcavities, three independent quantities can be measured, i.e. the electrical conductance, the photoluminescence intensity, and the wavelength of the optical resonance. We monitored the change of these three parameters as a function of NO2 (0.5-5 ppm), ethanol (300-15000 ppm) and relative humidity (0-100%). Preliminary results confirm that the examined species affect the parameters in a different way, both as a relative change and as dynamic.

Abstract: OBJETIVO: Com o crescente uso da artéria radial como enxerto aortocoronário, torna-se necessário reavaliar os critérios utilizados para a sele o desse vaso no pré-operatório da cirurgia de revasculariza o miocárdica. O objetivo deste estudo foi correlacionar a avalia o da viabilidade do vaso pelo cirurgi o cardíaco no per-operatório com o estudo de sele o da artéria radial pelos métodos n o invasivos, como o ecocolor Doppler e a fotopletismografia digital. CASUíSTICA E MéTODOS: Foram estudadas, entre julho de 1998 e maio de 2000, 78 artérias radiais e 78 artérias ulnares de 39 pacientes selecionados para cirurgia de revasculariza o miocárdica. O estudo foi realizado bilateralmente, utilizando aparelhos de ultra-sonografia ATL-HDI 5000 e Acuson-Sequóia 512, e o aparelho de fotopletismografia Parks Vascular Mini-Lab Model 1052-C. A artéria radial foi considerada passível de ser utilizada como enxerto aortocoronário, quando preenchia os seguintes critérios: ausência de ateromatose ou oclus o da artéria radial e ulnar ipsilateral, diametro interno da artéria radial maior ou igual a 2,5mm, avaliados pelo ecocolor Doppler, e presen a de onda de pulso em dois ou mais dígitos durante a compress o radial, avaliada pela fotopletismografia. RESULTADOS: Dentre as 78 artérias radiais estudadas, 64 (82%) foram consideradas apropriadas para utiliza o como enxerto aortocoronário e 12 (18,7%) n o apropriadas. Dos 39 pacientes selecionados, 24 (61,5%) foram submetidos à cirurgia de revasculariza o miocárdica com utiliza o da artéria radial e a correla o entre a viabilidade da artéria radial avaliada pelo cirurgi o durante o per-operatório com a avalia o pré-operatória pelo ecocolor Doppler e pela fotopletismografia para sele o da artéria radial foi de 100%. A contra-indica o da retirada de 12 (18,7%) artérias radiais levou à altera o do planejamento cirúrgico de dois pacientes, devido ao comprometimento bilateral. Em 3 pacientes que, por diferentes motivos, n o foram submetidos ao estudo pelo Ecocolor Doppler e pela fotopletismografia, a avalia o clínica da perviedade da artéria radial utilizando a manobra de Allen n o foi suficiente para afastar a presen a de calcifica o da parede arterial encontrada no ato operatório, impossibilitando o uso dessa artéria como enxerto. CONCLUS O: Os autores concluem que a sele o da artéria radial para utiliza o como ponte aortocoronária, avaliada por testes n o invasivos, como o ECD e a fotopletismografia, é eficaz, pois a associa o desses métodos apresenta excelente correla o com os achados per-operatórios e permite
