O assistente social como mediador cultural em escolas públicas dos bairros de Guamá e Terra firme
I Congresso Internacional América Latina e Interculturalidade: América Latina e Caribe: cenários linguístico-culturais contemporâneos, 07, 08 e 09 de novembro de 2013 - UNILAA intervenção do Assistente Social nas atividades de arte e cultura nas instituições de ensino
fundamental e médio nos bairros do Guamá e da Terra Firme. Estudos anteriores constatam que estes
não são apenas espaços de violência, como registra a mídia. São espaços multiculturais e agregadores de
cultura antiviolência, onde os sujeitos artistas utilizam a arte como meio de transformação social,
através do método fenomenológico busco contribuir para a sistematização da intervenção do assistente
social na área da educação e cultura, identificando as atividades de arte e cultura nas instituições de
ensino fundamental e médio, importância nas instituições em que são desenvolvidas e habilidades
requeridas ao profissional de Serviço Social. A metodologia conduziu a investigação nos respectivos
bairros com os alunos que estudam nas instituições de ensino fundamental e médio nos bairros, por
meio de aplicação de questionários sócioeconômicocultural que ao definir cultura identificaram as
manifestações culturais que estavam ocorrendo no mês (junho/2013) em que o questionário foi aplicado,
quanto ao fazer profissional do Serviço Social, a maioria dos alunos da escola pública estadual
relacionam o trabalho do assistente social com a prestação de ajuda e auxílio. Os alunos da escola
pública federal demonstraram maior efetividade e segurança na resposta, em consonância com o Código
de Ética do Assistente Social, também foi realizada entrevista semiestruturada com a Assistente Social
das instituições de ensino. Segundo a pesquisa identificase a sobrecarga do profissional do serviço social
com as demandas postas pelos alunos no processo de ensino e aprendizagem, de tal modo que não
possa acompanhar atividades de arte e cultura desenvolvidas nas instituições de ensino, e por meio de
levantamentos bibliográficos e visitas de observação ao local de pesquisa foi possível identificar as
atividades, projetos de extensão de arte e cultura nas instituições de ensino
On Determining Dead Layer and Detector Thicknesses for a Position-Sensitive Silicon Detector
In this work, two particular properties of the position-sensitive, thick
silicon detectors (known as the "E" detectors) in the High Resolution Array
(HiRA) are investigated: the thickness of the dead layer on the front of the
detector, and the overall thickness of the detector itself. The dead layer
thickness for each E detector in HiRA is extracted using a measurement of alpha
particles emitted from a Pb pin source placed close to the detector
surface. This procedure also allows for energy calibrations of the E detectors,
which are otherwise inaccessible for alpha source calibration as each one is
sandwiched between two other detectors. The E detector thickness is obtained
from a combination of elastically scattered protons and an energy-loss
calculation method. Results from these analyses agree with values provided by
the manufacturer.Comment: Accepted for publication in Nuclear Instruments and Methods in

Measurement of Cosmic-ray Muons and Muon-induced Neutrons in the Aberdeen Tunnel Underground Laboratory
We have measured the muon flux and production rate of muon-induced neutrons
at a depth of 611 m water equivalent. Our apparatus comprises three layers of
crossed plastic scintillator hodoscopes for tracking the incident cosmic-ray
muons and 760 L of gadolinium-doped liquid scintillator for producing and
detecting neutrons. The vertical muon intensity was measured to be cmssr. The yield of
muon-induced neutrons in the liquid scintillator was determined to be
neutrons/(gcm). A fit to the recently measured neutron
yields at different depths gave a mean muon energy dependence of for liquid-scintillator targets.Comment: 14 pages, 17 figures, 3 table
Application of Information Theory in Nuclear Liquid Gas Phase Transition
Information entropy and Zipf's law in the field of information theory have
been used for studying the disassembly of nuclei in the framework of the
isospin dependent lattice gas model and molecular dynamical model. We found
that the information entropy in the event space is maximum at the phase
transition point and the mass of the cluster show exactly inversely to its
rank, i.e. Zipf's law appears. Both novel criteria are useful in searching the
nuclear liquid gas phase transition experimentally and theoretically.Comment: 5 pages, 5 figure

KATANA - a charge-sensitive triggering system for the SRIT experiment
KATANA - the Krakow Array for Triggering with Amplitude discrimiNAtion - has
been built and used as a trigger and veto detector for the SRIT TPC at
RIKEN. Its construction allows operating in magnetic field and providing fast
response for ionizing particles, giving the approximate forward multiplicity
and charge information. Depending on this information, trigger and veto signals
are generated. The article presents performance of the detector and details of
its construction. A simple phenomenological parametrization of the number of
emitted scintillation photons in plastic scintillator is proposed. The effect
of the light output deterioration in the plastic scintillator due to the
in-beam irradiation is discussed.Comment: 14 pages, 11 figure
The Impact of dose heterogeneity on late normal tissue complication risk after hypofractionated whole breast radiotherapy
Background and purpose: linear quadratic models predict that hypofractionation increases the biological effect of physical dose inhomogeneity. The clinical significance of this effect was tested retrospectively in a trial of adjuvant breast hypofractionation.Methods: the UK FAST trial randomised 915 women after breast conservation surgery between standard fractionation and two dose levels of a 5-fraction regimen delivering 5.7 or 6.0 Gy fractions in 5 weeks, using 3D dosimetry. Logistic regression tested for association between the absolute volumes receiving different isodose level >100% of prescribed dose (hotspots) and the risk of change in 2-year photographic breast appearance. The strength of this association was compared between control and hypofractionated groups.Results: three hundred and ninety datasets from 11 participating centres were available for analysis. At 2 years post-randomisation, 81 (20.8%) had mild change and 24 (6.2%) had marked change in photographic breast appearance. After adjusting for breast size and surgical deficit, there was no statistically significant association between the risk of 2-year change in breast appearance and dose inhomogeneity in either the control or hypofractionated schedules, according to the various definitions of hotspots analysed. The magnitude of the effect of dosimetry on 2-year change in breast appearance did not vary significantly between control and hypofractionated schedules for any of the dosimetry parameters (p > 0.05 for all heterogeneity tests).Conclusion: dose inhomogeneity had no greater impact on the risk of 2-year change in photographic breast appearance after hypofractionated breast radiotherapy than after standard fractionatio
Determination of energy-dependent neutron backgrounds using shadow bars
Understanding the neutron background is essential for determining the neutron
yield from nuclear reactions. In the analysis presented here, the shadow bars
are placed in front of neutron detectors to determine the energy dependent
neutron background fractions. The measurement of neutron spectra with and
without shadow bars is important to determine the neutron background more
accurately. The neutron background, along with its sources and systematic
uncertainties, are explored with a focus on the impact of background models and
their dependence on neutron energy.Comment: 7 pages, 10 figure
