Sistema de avaliação de impactos de inovações tecnológicas: INOVA-tec system v. 2.0.
Este trabalho apresenta uma metodologia para a avaliação dos impactos de inovações tecnológicas, fornecendo informações organizadas de acordo com critérios e indicadores nas diversas dimensões onde os impactos da tecnologia sob avaliação podem ser percebidos. O método consiste de um sistema que permite a análise: i) do cenário no qual a tecnologia será introduzida, a partir da geração do índice de significância, e ii) do desempenho da inovação, pela análise dos indicadores de impacto que irão compor o índice de magnitude. Este sistema conta com uma ferramenta de apoio, o software "INOVA-tec v 2.0", com informações apresentadas como um norteador para permitir uma avaliação instruída e embasada.bitstream/item/42711/1/documentos-86.pd
Low-energy neutrinos at off-axis from a standard beta-beam
We discuss a scenario to extract up to 150 MeV neutrinos at a standard
beta-beam facility using one and two detectors off-axis. In particular we show
that the high-energy component of the neutrino fluxes can be subtracted through
a specific combination of the response of two off-axis detectors. A systematic
analysis of the neutrino fluxes using different detector geometries is
presented, as well as a comparison with the expected fluxes at a low-energy
beta-beam facility. The presented option could offer an alternative way to
perform low-energy neutrino experiments.Comment: 9 pages, 6 figure
Crystal structure and physical properties of EuPtIn intermetallic antiferromagnet
We report the synthesis of EuPtIn single crystalline platelets by the
In-flux technique. This compound crystallizes in the orthorhombic Cmcm
structure with lattice parameters \AA, \AA and
\AA. Measurements of magnetic susceptibility, heat capacity,
electrical resistivity, and electron spin resonance (ESR) reveal that
EuPtIn is a metallic Curie-Weiss paramagnet at high temperatures and
presents antiferromagnetic (AFM) ordering below K. In addition, we
observe a successive anomaly at K and a spin-flop transition at
T applied along the -plane. In the paramagnetic state, a
single Eu Dysonian ESR line with a Korringa relaxation rate of Oe/K is observed. Interestingly, even at high temperatures, both ESR
linewidth and electrical resistivity reveal a similar anisotropy. We discuss a
possible common microscopic origin for the observed anisotropy in these
physical quantities likely associated with an anisotropic magnetic interaction
between Eu 4 electrons mediated by conduction electrons.Comment: 5 pages, 5 figure
Control of fluorescence in quantum emitter and metallic nanoshell hybrids for medical applications
We study the light emission from quantum emitter and double metallic
nanoshell hybrid systems. Quantum emitters act as local sources which transmit
their light efficiently due to a double nanoshell near field. The double
nanoshell consists a dielectric core and two outer nanoshells

Perspectives on quality mental health care from Brazilian and Cape Verdean outpatients: Implications for effective patient-centered policies and models of care
Mental health providers are increasingly coming into contact with large and growing multi-racial/ethnic and immigrant patient populations in the United States. Knowledge of patient perspectives on what constitutes quality mental health care is necessary for these providers. The aim of this study was to identify indicators of quality of mental health care that matter most to two underrepresented immigrant patient groups of Portuguese background: Brazilians and Cape Verdeans. A qualitative design was adopted using focus group discussions. Six focus groups of patients (n=24 Brazilians; n=24 Cape Verdeans) who received outpatient mental health treatment through public safety net clinics in the northeast region of the United States were conducted. The Consensual Qualitative Research analytic method allowed us to identify three quality of care domains: provider performance, aspects of mental health care environment, and effectiveness of mental health care treatment. Provider performance was associated with five categories: relational, communication, linguistic, cultural, and technical competencies. Aspects of mental health care environment were linked to two categories: psychosocial and physical environment. Effectiveness of mental health care treatment was related to two categories: therapeutic relationship and treatment outcomes. Study findings provide useful data for the development of more culturally appropriate and effective patient-centered models and policies in mental health care
Social Media: The Meeting Before the Meeting
Now, more than ever, many students' first contact with your program very well could be from your social media presence. This roundtable will explore helpful communicating tips and tools to bridge the intergenerational gap between staff and students that will help participants engage students and introduce their program to a broader audience

Caracterização da coleção de germoplasmam de xampu (Zingiber spectabile Griff) e (Zingiber zerumbet).
As espécies Zingiber spectabile Griff e Zingiber zerumbet também chamados de xampu, pertencentes a família Zingiberaceae, facilmente multiplicadas, vem sendo utilizadas para corte e nas floriculturas para diversos fins e apresentações sendo principalmente ornamentais. A caracterização e avaliação das mesmas se tornam importante fator dentro do banco germoplasma para se avalizar as variações entre os acessos. Sendo assim o trabalho teve por objetivo caracterizar morfologicamente acessos introduzidos das espécies Zingiber spectabile Griff e Zingiber zerumbet, da coleção da Embrapa Amazônia Oriental conservadas no campo experimental em Belém-Pa. A caracterização foi realizada em acessos provenientes de sementes e rizomas da coleção de germoplasma de xampu, localizada no campo experimental da Embrapa Amazônia Oriental Belém-Pará. A caracterização morfológica discriminou caracteres que diferenciam acessos entre e dentro das duas espécies. Os acessos de xampu mostraram variações determinantes com relação a cor da inflorescência sendo este caráter o mais expressivo para essa espécie. Os acessos de xampu comercial e nativo podem ser utilizados em cultivo por produtores por apresentarem diversidade de cores e boa durabilidade pós corte
