Management impacts on Carex assiniboinensis and Cardamine concatenata on the Ottawa National Forest

Monitoring of herbaceous plants on the Ottawa National Forest (ONF) is used to understand the impact of forest management on understory composition and site conditions. In their planning, national forests are required to take into account management impacts on diversity and ecosystem health. The effect of management on understory species is dependent on various factors, including the intensity of disturbance and the biology of the plant. In the first study in this report, a population of Carex assiniboinensis, a Michigan state threatened species, was monitored for seven seasons including before logging commenced, in order to determine the sedge’s response to a single-tree selection harvest. Analyses provided insights for management of C. assiniboinensis at the stand level over the short-term. In the second study in this report, the use of the cutleaf toothwort (Cardamine concatenata) as a Management Indicator Species on the ONF was reviewed. Data were analyzed to determine the suitability of using C. concatenata to monitor impacts of forest management on site conditions. The various factors that affect understory species population dynamics illuminated the challenges of using indicator species to monitor site conditions. Insights from the study provide a greater understanding of management impacts on understory species across the Ottawa National Forest.

Nonlinear optics with cold Rb atoms using tapered optical nanofibres

Optical nanofibres (ONFs) are very thin optical waveguides with sub-wavelength diameters. ONFs have very high evanescent fields and the guided light is confined strongly in the transverse direction. These fibres can be used to achieve strong light-matter interactions. Atoms around the waist of an ONF can be probed by collecting the atomic fluorescence coupling or by measuring the transmission (or the polarisation) of the probe beam sent through it. This thesis presents experiments using ONFs for probing and manipulating laser-cooled 87Rb atoms. As an initial experiment, a single mode ONF was integrated into a magneto-optical trap (MOT) and used for measuring the characteristics of the MOT, such as the loading time and the average temperature of the atom cloud. The effect of a near-resonant probe beam on the local temperature of the cold atoms has been studied. Next, the ONF was used for manipulating the atoms in the evanescent fields region in order to generate nonlinear optical effects. Four-wave mixing, ac Stark effect (Autler-Townes splitting) and electromagnetically induced transparency have been observed at unprecedented ultralow power levels. In another experiment, a few-mode ONF, supporting only the fundamental mode and the first higher order mode group, has been used for studying cold atoms. A higher pumping rate of the atomic fluorescence into the higher order fibreguided modes and more interactions with the surrounding atoms for higher order mode evanescent light, when compared to signals for the fundamental mode, have been identified. The results obtained in the thesis are particularly for a fundamental understanding of light-atom interactions when atoms are near a dielectric surface and also for the development of fibre-based quantum information technologies. Atoms coupled to ONFs could be used for preparing intrinsically fibre-coupled quantum nodes for quantum computing and the studies presented here are significant for a detailed understanding of such a system.

Dentro del conjunto de comedias dedicadas a la historia de Hungría, Lope de Vega cuenta con tres comedias con numerosas similitudes: El príncipe melancólico, El cuerdo loco y La sortija del olvido. Este trabajo examina las relaciones de intertextualidad y reescritura en las tres obras, así como algunos aspectos del desarrollo de la comedia palatina lopesca.

Capacitação do doente oncológico com doença avançada/cuidador para a gestão da dor em domicílio

Introdução: A dor oncológica é assustadora, tanto para o doente como para o cuidador, quer pela intensidade como por vezes surge, quer pela associação a outros sintomas e alterações nas atividades de vida, causando sofrimento e isolamento social. Capacitar o doente e o cuidador para a gestão da dor, passa por ensinar a identificar, a monitorizar, a relacionar a dor com outros sintomas e com as atividades de vida. Assim como, ensinar a gerir de forma adequada a terapêutica prescrita. Objetivos: Avaliar a aplicação de um programa educativo na capacitação do doente oncológico/cuidador com doença avançada, na gestão da dor em domicílio; Identificar intervenções de Enfermagem no decurso da aplicação do programa; Identificar dificuldades na capacitação do doente/cuidador; Avaliar a capacidade do doente antes e após a aplicação do programa educativo. Metodologia: Este estudo foi realizado no âmbito do projeto de doutoramento. Trata-se de um estudo longitudinal quase experimental, em que foi avaliado o conhecimento relativo à dor antes e depois da aplicação do programa e foi feita uma análise transversal dos registos elaborados pelos participantes, após os vários momentos de contacto/ensino. Participaram no estudo 52 doentes oncológicos com doença avançada, que frequentavam um hospital de dia, em consulta e tratamento sintomático ou curativo de 2ª ou 3ª linha. Resultados: A aplicação do programa educativo exigiu contactos (momentos de ensino) com os participantes, verificandose que 75% dos participantes iniciaram o programa no 1º contacto e 25% iniciaram no 2º contacto. O número de contactos por participante variou entre os 2 e os 6, tendo-se efetuado 3 contactos a 52% dos participantes, 4 a 25% e 2 a 21%. Um participante teve 5 momentos de contacto e outro, 6 momentos. Quanto à capacidade para realização completa dos registos, verificou-se que no final, 50% dos participantes realizaram registos completos de forma independente, destes, 8% adotaram o comportamento correto na tomada da medicação, 6% não modificaram o comportamento e nos restantes esta mudança não se revelou significativa. Trinta e três por cento dos participantes não conseguem realizar os registos sem ajuda, devido ao agravamento dos sintomas, ou baixo nível de literacia, mas identificam e avaliam a dor e outros sintomas. Quinze por cento realizam os registos de forma incompleta e 1 participante apenas descreve a experiência de dor. Conclusões: O desenvolvimento de um programa educativo para capacitação exige uma avaliação do número de momentos de interação necessários para que o processo ocorra. Existem condicionalismos à efetivação dos momentos de contacto, tais como, o estado clínico do doente, a literacia e o desenvolvimento do processo de saúde doença. A aplicação do programa em 3 momentos de ensino foi o mais frequente nesta população. Após a aplicação do programa, a maioria dos doentes/ cuidadores apresentam capacidade para identificar, avaliar e monitorizar a dor e outros sintomas, assim como as alterações nas atividades de vida. Verificou-se uma melhoria na gestão da terapêutica antiálgica.

A methodological framework to assess the carbon balance of tropical managed forests.

Background: Managed forests are a major component of tropical landscapes. Production forests as designated by national forest services cover up to 400 million ha, i.e. half of the forested area in the humid tropics. Forest management thus plays a major role in the global carbon budget, but with a lack of unified method to estimate carbon fluxes from tropical managed forests. In this study we propose a new time- and spatially-explicit methodology to estimate the above-ground carbon budget of selective logging at regional scale. Results: The yearly balance of a logging unit, i.e. the elementary management unit of a forest estate, is modelled by aggregating three sub-models encompassing (i) emissions from extracted wood, (ii) emissions from logging damage and deforested areas and (iii) carbon storage from post-logging recovery. Models are parametrised and uncertainties are propagated through a MCMC algorithm. As a case study, we used 38 years of National Forest Inventories in French Guiana, northeastern Amazonia, to estimate the above-ground carbon balance (i.e. the net carbon exchange with the atmosphere) of selectively logged forests. Over this period, the net carbon balance of selective logging in the French Guianan Permanent Forest Estate is estimated to be comprised between 0.12 and 1.33 Tg C, with a median value of 0.64 Tg C. Uncertainties over the model could be diminished by improving the accuracy of both logging damage and large woody necromass decay submodels. Conclusions: We propose an innovating carbon accounting framework relying upon basic logging statistics. This flexible tool allows carbon budget of tropical managed forests to be estimated in a wide range of tropical regions
