dissertationThis work presents the results of various investigations using various techniques of hyperpolarizing the nuclei of atoms. Hyperpolarization implies magnetic order in excess of the thermal order obtained naturally as described by Curie's law. The main portion of this work presents the results of a detailed experimental exploration of predictions arising from a new model of transverse nuclear spin relaxation in quantum systems, based on possible manifestations of microscopic chaos in quantum systems. Experiments have been carried out on a number of hyperpolarized xenon samples, each di ering in its relative percentage of xenon isotopes in order to vary the homonuclear and heteronuclear dipole couplings in the spin system. The experiments were performed under a variety of conditions in an attempt to observe the behaviors predicted by the model. Additionally, much more extensive measurements were made on a number of samples of solid CaF2 in both single crystal and powder forms. These samples, although thermally polarized, were observed with superior signal to noise ratios than even the hyperpolarized xenon solids, allowing for more precise measurements for comparison to the theory. This work thus contains the rst experimental evidence for the majority of the model's predictions. Additionally, this work contains the rst precise measurements of the frequency-shift enhancement parameters for 129Xe and krypton in the presence of spin-polarized Rb. The determination of these important numbers will be useful to many groups who utilize spinexchange optical pumping in their labs. This work built on the prior knowledge of a precise number for the frequency-shift enhancement parameter of 3He in Rb vapor. Finally, I detail work using NMR to detect nuclear-spin polarization enhancement in silicon phosphorus by a novel, photo-induced hyperpolarization technique developed by the Boehme research group at the University of Utah. Signiif cant nuclear polarization enhancements were observed by the Boehme group due to electron-photon interactions in semiconductor soilds; these enhancements were observed by their e ffects on the ambient electrons and measured with electron spin resonance techniques. The work described here details experiments to observe the enhanced nuclear polarization by directly measuring the intensity increase in an NMR measurement
IN-SERVICE ENGLISH TEACHER EDUCATION FOR DIGITAL ENVIRONMENTS: PERCEPTIONS ON THEORETICAL BASES
This paper aims at analyzing the perceptions of English teachers about the theoretical bases discussed in a teacher development course named Digital Environments: theory and practice in the classroom. The course, which focuses on promoting digital literacies, is offered by the Federal University of Sergipe (UFS) in partnership with the Undergraduate Center for Distance Education at UFS and the research group E-Lang from UNICAMP. Among the theoretical bases of this study are the authors who discuss the inclusion of digital technologies at schools and English classes as well as the notion of digital literacies (BAWDEN, 2008; BRAGA, 2013; COLL ET AL, 2010; LANKSHEAR & KNOBEL, 2008; LEMKE, 1998; SANTAELLA, 2013). For data analysis, it is taken into accountthe messages posted on the platform where the course is offered, i.e. discussion forums and reflective electronic diary. The results show how the participating teachers understand conceptions such as technology, hyperlinks and digital literacies. In addition, it is observed the relevance of discussing issues related to the official guidelines for teaching foreign languages in Brazil, which leads to the need for the teacher to be constantly involved in professional develpoment

Uso do conhecimento tradicional para promover a inclusão socioeconômica de comunidades locais
El artÃculo señala el papel desempeñado por institutos públicos de investigación en Brasil en la promoción de la inclusión socioeconómica de comunidades locales por medio del uso del conocimiento tradicional y de la medicina popular. Organizaciones no gubernamentales y cooperativas son importantes para recaudar recursos, defender los intereses de las comunidades locales e influenciar cambios en el ordenamiento jurÃdico. Mientras tanto, exigencias de carácter legal relacionadas con las Buenas Prácticas de Fabricación y con la necesidad de comprobación de la eficiencia de medicamentos, impuestas por la Agencia Brasileña de Vigilancia Sanitaria, tienden a demandar la intervención de un instituto público de investigación capaz de auxiliar dichas comunidades en la aprobación y comercialización de medicamentos producidos a partir de plantas medicinales. Por lo tanto, institutos públicos de investigación son esenciales para realizar estudios cientÃficos que comprueben la eficiencia de las plantas medicinales y para auxiliar a las comunidades locales en la creación de la infraestructura necesaria para atender las exigencias de la Agencia con relación a las Buenas Prácticas de Fabricación.This paper discusses the key role played by public research institutes for promoting socioeconomic inclusion of local communities based on traditional knowledge and traditional medicine. Nongovernmental organizations and cooperatives have had an important role in raising financial resources, being involved with advocacy of local communities and advancing legislation changes. But strict best manufacturing practices regulations imposed by the Brazilian National Health Surveillance Agency on the requirements for approval and commercialization of drugs based on herbal medicine products call for the involvement of strong public research institutes capable of supporting community-based pharmacies. Thus, public research institutes are pivotal as they can conduct scientific research studies to evidence the efficacy of herbal medicine products and help building the capacity of local communities to comply with current regulations.O artigo mostra o papel desempenhado por institutos públicos de pesquisa no Brasil na promoção da inclusão socioeconômica de comunidades locais por meio do uso do conhecimento tradicional e da medicina popular.

Estratégias de apoio para melhorar a qualidade do ar em áreas portuárias
Despite their key contribution to economic development, harbours pose
environmental threat, affecting air quality, local climate, and human health, due to
the release of several pollutants. Poor local air quality episodes are particularly
concerning when harbours are located near densely populated urban areas,
threatening inhabitants’ health.
This Thesis was focused on the assessment of the impact of harbour emissions on
the air quality over harbours and their surrounding urban areas, with a final goal of
producing guidelines to support decision-making in the harbour sector and air
quality management, using Port of Leixões as a case-study. After reviewing the
state-of-the-art in this research field, a high-resolution emission inventory was
developed, based on the two most used methodologies within the scientific
community. Data about ship and cargo handling equipment were compiled, allowing
the quantification of emissions and identification of their main sources. The
comparison of the two methodologies indicates that a new harmonized methodology
is recommended, besides the need of continuous update of emission factors and
activity data.
Having the detailed emission inventory, the community-scale webtool C-PORT was
applied for the first time in European harbours to simulate the impact of the maritime
emissions on local air quality. The comparison of modelled and observed values
validated its application for the case study of Port of Leixões. The highest PM10
concentrations were found near the South Container Terminal of Port of Leixões,
while NOx concentrations above 100 µg/m3 were also found near the highway.
Land-based emission sources exhibited the highest contribution (around 80 %) to
the PM10 concentrations in the study area, while 50 % of NOx concentration was
due to docked ships.
Mitigation measures were investigated and assessed to improve air quality in
harbours and their surroundings. In a case-study, pollutant dispersion was
addressed, aiming to control fugitive petcoke emissions and their impact on Port of
Aveiro’s neighbour communities. Optimal structure, size and position of a physical
barrier were defined based on numerical and physical modelling, achieving a
maximum reduction in petcoke dust reaching the nearby residential area of 74 – 88
% for the most frequent/critical wind directions. The studied barrier has been
implemented in the field and monitoring campaigns are currently being carried out
to assess its effectiveness.Apesar do seu papel-chave no desenvolvimento económico, os portos marÃtimos
constituem uma ameaça ambiental, com impactes na qualidade do ar, clima local,
e saúde humana, devido à emissão de inúmeros poluentes. Episódios de má
qualidade do ar a nÃvel local são particularmente preocupantes no caso de portos
localizados nas imediações de áreas urbanas densamente povoadas, pondo em
risco a saúde dos habitantes locais.
Esta Tese focou-se no impacte das emissões portuárias na qualidade do ar em
portos e suas vizinhanças urbanas. O objetivo final foi a produção de
recomendações de suporte à tomada de decisão no setor portuário e gestão da
qualidade do ar, usando o Porto de Leixões como caso-de-estudo. Após uma
revisão do estado-da-arte neste campo, foi desenvolvido um inventário de
emissões de alta-resolução, aplicando as duas metodologias mais frequentemente
usadas na comunidade cientÃfica. Foram compilados dados sobre navios e
equipamentos portuários, permitindo a quantificação das emissões e identificação
das suas fontes maioritárias. Deste procedimento resultaram recomendações
sobre o desenvolvimento de uma nova metodologia harmonizada. Ficou ainda
evidenciada a relevância da atualização dos fatores de emissão e dos dados
disponÃveis sobre as diferentes atividades portuárias.
Dispondo deste inventário de emissões, o C-PORT, uma ferramenta web de escala
comunitária, foi aplicado pela primeira vez em portos europeus, para simular o
impacte das emissões marÃtimas na qualidade do ar local. A comparação dos
valores modelados com medições de campo validou a aplicação desta ferramenta
ao caso-de-estudo do Porto de Leixões. A concentração mais elevada de PM10 foi
registada no Terminal de Contentores Sul, registando-se também elevada (> 100
µg/m3
) concentração de NOx junto à autoestrada vizinha. A maior contribuição
(cerca de 80 %) para a emissão global de PM10 na área de estudo adveio de fontes
de emissão terrestres, enquanto os navios atracados contribuÃram com cerca de
50 % das emissões de NOx. Esta Tese inclui a análise de medidas de mitigação
capazes de melhorar a qualidade do ar em portos marÃtimos e sua vizinhança. O
caso-de-estudo apresentado foca-se na dispersão de poluentes, com o intuito de
controlar a emissão de partÃculas de petcoke do Porto de Aveiro, e o seu impacte
nas comunidades vizinhas. Com esse objetivo, foi estudada, através de simulação
fÃsica e numérica, a composição, dimensão e posicionamento de uma barreira
fÃsica. A solução otimizada permitiu reduzir em 74 % – 88 % para as direções de
vento mais frequentes/crÃticas nesta região, estando atualmente implementada no
terreno.Programa Doutoral em Ciências e Engenharia do Ambient
The Differential Effects of Visual and Auditory Information in Determining Meanings of Derived Words at Third and Fifth Grade Levels
The primary purpose of this research was to investigate the differential effects of visual (graphic) and auditory (phonetic) information in accessing meanings of derived words which are variant at the surface phonetic level, but retain in their orthography a relationship to the deeper lexical level. These effects were examined developmentally at the third and fifth grade levels using a researcher-designed multiple-choice test. The test instrument consisted of derived words not typically found in basal series at the grade levels under consideration and also met the criteria of pronunciation shift while retaining orthographic similarity to the base word. The test was presented in two forms at each grade level in a suburban western New York school district. The Visual Form was presented to 105 third grade and 127 fifth grade subjects. The Auditory Form was presented to 94 third grade and 96 fifth grade subjects. The secondary purpose was to examine relationships between ability to determine meanings of derived words in each modality and performance on a standardized reading measure, the Metropolitan Achievement Test. A two-way analysis of variance and a product-moment correlation-study were employed to test the hypotheses at the .01 and .001. level of significance. The data confirmed that children at both grade levels can utilize graphic information to determine meanings of derived words. The data also indicated a relationship between reading achievement and performance on the Visual Form of the test at the third and fifth grade levels, and the Auditory Form of the test at the third grade level. A study focusing on the fifth grade level was recommended
Phase relationship between the long-time beats of free induction decays and spin echoes in solids
Journal ArticleRecent theoretical work on the role of microscopic chaos in the dynamics and relaxation of many-body quantum systems has made several experimentally confirmed predictions about the systems of interacting nuclear spins in solids, focusing in particular on the shapes of spin echo responses measured by nuclear magnetic resonance. These predictions were based on the idea that the transverse nuclear spin decays evolve in a manner governed at long times by the slowest decaying eigenmode of the quantum system, analogous to a chaotic resonance in a classical system. The present paper extends the above investigations both theoretically and experimentally. On the theoretical side, the notion of chaotic eigenmodes is used to make predictions about the relationships between the long-time oscillation phase of the nuclear free induction decay and the amplitudes and phases of spin echoes. On the experimental side, the above predictions are tested for the nuclear spin decays of 19F in CaF2 crystals and 129Xe in frozen xenon. Good agreement between the theory and the experiment is found
