Earthquakes of the Nepal Himalaya : towards a physical model of the seismic cycle

Home to hundreds of millions of souls and land of excessiveness, the Himalaya is also the locus of a unique seismicity whose scope and peculiarities still remain to this day somewhat mysterious. Having claimed the lives of kings, or turned ancient timeworn cities into heaps of rubbles and ruins, earthquakes eerily inhabit Nepalese folk tales with the fatalistic message that nothing lasts forever. From a scientific point of view as much as from a human perspective, solving the mysteries of Himalayan seismicity thus represents a challenge of prime importance. Documenting geodetic strain across the Nepal Himalaya with various GPS and leveling data, we show that unlike other subduction zones that exhibit a heterogeneous and patchy coupling pattern along strike, the last hundred kilometers of the Main Himalayan Thrust fault, or MHT, appear to be uniformly locked, devoid of any of the “creeping barriers” that traditionally ward off the propagation of large events. The approximately 20 mm/yr of reckoned convergence across the Himalaya matching previously established estimates of the secular deformation at the front of the arc, the slip accumulated at depth has to somehow elastically propagate all the way to the surface at some point. And yet, neither large events from the past nor currently recorded microseismicity nearly compensate for the massive moment deficit that quietly builds up under the giant mountains. Along with this large unbalanced moment deficit, the uncommonly homogeneous coupling pattern on the MHT raises the question of whether or not the locked portion of the MHT can rupture all at once in a giant earthquake. Univocally answering this question appears contingent on the still elusive estimate of the magnitude of the largest possible earthquake in the Himalaya, and requires tight constraints on local fault properties. What makes the Himalaya enigmatic also makes it the potential source of an incredible wealth of information, and we exploit some of the oddities of Himalayan seismicity in an effort to improve the understanding of earthquake physics and cipher out the properties of the MHT. Thanks to the Himalaya, the Indo-Gangetic plain is deluged each year under a tremendous amount of water during the annual summer monsoon that collects and bears down on the Indian plate enough to pull it away from the Eurasian plate slightly, temporarily relieving a small portion of the stress mounting on the MHT. As the rainwater evaporates in the dry winter season, the plate rebounds and tension is increased back on the fault. Interestingly, the mild waggle of stress induced by the monsoon rains is about the same size as that from solid-Earth tides which gently tug at the planets solid layers, but whereas changes in earthquake frequency correspond with the annually occurring monsoon, there is no such correlation with Earth tides, which oscillate back-and-forth twice a day. We therefore investigate the general response of the creeping and seismogenic parts of MHT to periodic stresses in order to link these observations to physical parameters. First, the response of the creeping part of the MHT is analyzed with a simple spring-and-slider system bearing rate-strengthening rheology, and we show that at the transition with the locked zone, where the friction becomes near velocity neutral, the response of the slip rate may be amplified at some periods, which values are analytically related to the physical parameters of the problem. Such predictions therefore hold the potential of constraining fault properties on the MHT, but still await observational counterparts to be applied, as nothing indicates that the variations of seismicity rate on the locked part of the MHT are the direct expressions of variations of the slip rate on its creeping part, and no variations of the slip rate have been singled out from the GPS measurements to this day. When shifting to the locked seismogenic part of the MHT, spring-and-slider models with rate-weakening rheology are insufficient to explain the contrasted responses of the seismicity to the periodic loads that tides and monsoon both place on the MHT. Instead, we resort to numerical simulations using the Boundary Integral CYCLes of Earthquakes algorithm and examine the response of a 2D finite fault embedded with a rate-weakening patch to harmonic stress perturbations of various periods. We show that such simulations are able to reproduce results consistent with a gradual amplification of sensitivity as the perturbing period get larger, up to a critical period corresponding to the characteristic time of evolution of the seismicity in response to a step-like perturbation of stress. This increase of sensitivity was not reproduced by simple 1D-spring-slider systems, probably because of the complexity of the nucleation process, reproduced only by 2D-fault models. When the nucleation zone is close to its critical unstable size, its growth becomes highly sensitive to any external perturbations and the timings of produced events may therefore find themselves highly affected. A fully analytical framework has yet to be developed and further work is needed to fully describe the behavior of the fault in terms of physical parameters, which will likely provide the keys to deduce constitutive properties of the MHT from seismological observations.

The role of women in fish processing: handling and marketing in Kainji Lake basin

The study assessed the contribution of women in fish handling, processing and marketing in Kainji Lake basin. Structured questionnaires were administered to three fishing villages selected at random. The fishing villages were Monai, Yuna, Fakun, and New Bussa market. The study revealed that women play vital roles in fisheries activities as producers, assistants to men preservers, traders and financiers. The notable fishing activity performed by women is processing right from the moment the boats or canoes land at sites. Women assist in emptying nets, sorting gutting and cleaning the catch. In most cases their activities involved salting smoking and drying using traditional processing techniques. Women are also involved in storage and marketing of both fresh and smoked fish. In spite of these important contribution, most women in the various fishing communities are illiterates, have little or no say in decision making in areas that affects their livelihood and are regarded as inferior fedex. Culture and religion also has significant impact on their contribution in fishing activities

Enhancement of fish production in Borno State with extension services

Borno State possesses great potentials for fish production both from inland fisheries and aquaculture. The socio-economic and environmental production factors are suitable for fish production. If the potential of the State were well harnessed, it would be playing significant roles in achieving self-sufficiency in fish production in Nigeria. But the situation at the moment is that its fisheries potentials are not being optimally utilized. While the inland waters of Lake Chad are currently being recklessly exploited, aquaculture development is given little or no attention. It is evident that there is a missing link between research results and the potential end users. Because information in fish production variables is a pre-requisite for fisheries development, the gap that exists between two poles must be bridged, fisheries Extension provides this important link between research result and the end users of research findings. The paper examines the importance of extension services as the key to unlock fish production information that are usually consigned to the pages of academic journals and research publications

Flight dynamics in Drosophila through a dynamically-scaled robotic approach

Flies are particularly adept at balancing the competing demands of delay tolerance, performance, and robustness during flight, which invites thoughtful examination of their multimodal feedback architecture. This dissertation examines stabilization requirements for inner-loop feedback strategies in the flapping flight of Drosophila, the fruit fly, against the backdrop of sensorimotor transformations present in the animal. Flies have evolved multiple specializations to reduce sensorimotor latency, but sensory delay during flight is still significant on the timescale of body dynamics. I explored the effect of sensor delay on flight stability and performance for yaw turns using a dynamically-scaled robot equipped with a real-time feedback system that performed active turns in response to measured yaw torque. The results show a fundamental tradeoff between sensor delay and permissible feedback gain, and suggest that fast mechanosensory feedback provides a source of active damping that compliments that contributed by passive effects. Presented in the context of these findings, a control architecture whereby a haltere-mediated inner-loop proportional controller provides damping for slower visually-mediated feedback is consistent with tethered-flight measurements, free-flight observations, and engineering design principles. Additionally, I investigated how flies adjust stroke features to regulate and stabilize level forward flight. The results suggest that few changes to hovering kinematics are actually required to meet steady-state lift and thrust requirements at different flight speeds, and the primary driver of equilibrium velocity is the aerodynamic pitch moment. This finding is consistent with prior hypotheses and observations regarding the relationship between body pitch and flight speed in fruit flies. The results also show that the dynamics may be stabilized with additional pitch damping, but the magnitude of required damping increases with flight speed. I posit that differences in stroke deviation between the upstroke and downstroke might play a critical role in this stabilization. Fast mechanosensory feedback of the pitch rate could enable active damping, which would inherently exhibit gain scheduling with flight speed if pitch torque is regulated by adjusting stroke deviation. Such a control scheme would provide an elegant solution for flight stabilization across a wide range of flight speeds.

Influence of composition on the structure and properties of Fe-Pd-P and Ni-Pd-P amorphous alloys

Ternary alloys of nickel-palladium-phosphorus and iron-palladium- phosphorus containing 20 atomic % phosphorus were rapidly quenched from the liquid state. The structure of the quenched alloys was investigated by X-ray diffraction. Broad maxima in the diffraction patterns, indicative of a glass-like structure, were obtained for 13 to 73 atomic % nickel and 13 to 44 atomic % iron, with palladium adding up to 80%.

Radial distribution functions were computed from the diffraction data and yielded average interatomic distances and coordination numbers. The structure of the amorphous alloys could be explained in terms of structural units analogous to those existing in the crystalline Pd₃P, Ni₃P and Fe₃P phases, with iron or nickel substituting for palladium. A linear relationship between interatomic distances and composition, similar to Vegard's law, was shown for these metallic glasses.

Electrical resistivity measurements showed that the quenched alloys were metallic. Measurements were performed from liquid helium temperatures (4.2°K) up to the vicinity of the melting points (900°K- 1000°K). The temperature coefficient in the glassy state was very low, of the order of 10^-4/°K. A resistivity minimum was found at low temperature, varying between 9°K and 14°K for Ni_x-Pd_80-x -P₂₀ and between 17°K and 96°K for Fe_x-Pd_80-x -P₂₀, indicating the presence of a Kondo effect. Resistivity measurements, with a constant heating rate of about 1.5°C/min,showed progressive crystallization above approximately 600°K.

The magnetic moments of the amorphous Fe-Pd-P alloys were measured as a function of magnetic field and temperature. True ferromagnetism was found for the alloys Fe₃₂-Pd₄₈-P₂₀ and Fe₄₄-Pd₃₆-P₂₀ with Curie points at 165° K and 380° K respectively. Extrapolated values of the saturation magnetic moments to 0° K were 1.70 µ_B and 2.10 µ_B respectively. The amorphous alloy Fe₂₃-Pd₅₇-P₂₀ was assumed to be superparamagnetic. The experimental data indicate that phosphorus contributes to the decrease of moments by electron transfer, whereas palladium atoms probably have a small magnetic moment. A preliminary investigation of the Ni-Pd-P amorphous alloys showed that these alloys are weakly paramagnetic.

Studies of ambient organic and inorganic aerosol in Southern California

The negative impacts of ambient aerosol particles, or particulate matter (PM), on human health and climate are well recognized. However, owing to the complexity of aerosol particle formation and chemical evolution, emissions control strategies remain difficult to develop in a cost effective manner. In this work, three studies are presented to address several key issues currently stymieing California's efforts to continue improving its air quality.

Gas-phase organic mass (GPOM) and CO emission factors are used in conjunction with measured enhancements in oxygenated organic aerosol (OOA) relative to CO to quantify the significant lack of closure between expected and observed organic aerosol concentrations attributable to fossil-fuel emissions. Two possible conclusions emerge from the analysis to yield consistency with the ambient organic data: (1) vehicular emissions are not a dominant source of anthropogenic fossil SOA in the Los Angeles Basin, or (2) the ambient SOA mass yields used to determine the SOA formation potential of vehicular emissions are substantially higher than those derived from laboratory chamber studies. Additional laboratory chamber studies confirm that, owing to vapor-phase wall loss, the SOA mass yields currently used in virtually all 3D chemical transport models are biased low by as much as a factor of 4. Furthermore, predictions from the Statistical Oxidation Model suggest that this bias could be as high as a factor of 8 if the influence of the chamber walls could be removed entirely.

Once vapor-phase wall loss has been accounted for in a new suite of laboratory chamber experiments, the SOA parameterizations within atmospheric chemical transport models should also be updated. To address the numerical challenges of implementing the next generation of SOA models in atmospheric chemical transport models, a novel mathematical framework, termed the Moment Method, is designed and presented. Assessment of the Moment Method strengths and weaknesses provide valuable insight that can guide future development of SOA modules for atmospheric CTMs.

Finally, regional inorganic aerosol formation and evolution is investigated via detailed comparison of predictions from the Community Multiscale Air Quality (CMAQ version 4.7.1) model against a suite of airborne and ground-based meteorological measurements, gas- and aerosol-phase inorganic measurements, and black carbon (BC) measurements over Southern California during the CalNex field campaign in May/June 2010. Results suggests that continuing to target sulfur emissions with the hopes of reducing ambient PM concentrations may not the most effective strategy for Southern California. Instead, targeting dairy emissions is likely to be an effective strategy for substantially reducing ammonium nitrate concentrations in the eastern part of the Los Angeles Basin.

Baryon number violation beyond the standard model

This thesis describes simple extensions of the standard model with new sources of baryon number violation but no proton decay. The motivation for constructing such theories comes from the shortcomings of the standard model to explain the generation of baryon asymmetry in the universe, and from the absence of experimental evidence for proton decay. However, lack of any direct evidence for baryon number violation in general puts strong bounds on the naturalness of some of those models and favors theories with suppressed baryon number violation below the TeV scale. The initial part of the thesis concentrates on investigating models containing new scalars responsible for baryon number breaking. A model with new color sextet scalars is analyzed in more detail. Apart from generating cosmological baryon number, it gives nontrivial predictions for the neutron-antineutron oscillations, the electric dipole moment of the neutron, and neutral meson mixing. The second model discussed in the thesis contains a new scalar leptoquark. Although this model predicts mainly lepton flavor violation and a nonzero electric dipole moment of the electron, it includes, in its original form, baryon number violating nonrenormalizable dimension-five operators triggering proton decay. Imposing an appropriate discrete symmetry forbids such operators. Finally, a supersymmetric model with gauged baryon and lepton numbers is proposed. It provides a natural explanation for proton stability and predicts lepton number violating processes below the supersymmetry breaking scale, which can be tested at the Large Hadron Collider. The dark matter candidate in this model carries baryon number and can be searched for in direct detection experiments as well. The thesis is completed by constructing and briefly discussing a minimal extension of the standard model with gauged baryon, lepton, and flavor symmetries.

Enfrentando mudanças e valorizando a vida - uma referência para a enfermeira no cuidado à mulher submetida à cirurgia ginecológica

Diversos estudos que abordam as repercussões das cirurgias ginecológicas na vida da mulher apontam para uma relação existente com aspectos subjetivos, em virtude da construção social da identidade feminina, indicando que a perda de órgãos ginecológicos pode interferir na maneira da mulher se perceber e se relacionar com o mundo. O presente estudo tem como objeto o processo de interação da mulher no contexto das cirurgias ginecológicas. Para isso foram formulados os objetivos: Descrever os significados da cirurgia ginecológica para a mulher submetida a este procedimento e Analisar o processo de interação da mulher com ela mesma e com o seu núcleo social a partir dos significados por ela atribuídos à cirurgia ginecológica, considerando o fenômeno da mutilação. O estudo de natureza qualitativa, do tipo descritivo-exploratório, teve como referencial teórico-metodológico o Interacionismo Simbólico e a Grounded Theory, que subsidiaram uma interpretação da ação e das relações das mulheres no contexto da cirurgia ginecológica e da mutilação, baseados na definição e interpretação de significados por elas atribuídos. Dos resultados emergiram quatro categorias: Investigando a doença e decidindo aceitar a cirurgia, A passagem pela cirurgia: vivendo o processo de resolução do problema, Enfrentando as mudanças impostas pela cirurgia e Valorizando a vida. Evidenciou-se que ao receber o diagnóstico da doença, a mulher interage com dúvidas, medos, a busca por informação e pelos benefícios da cirurgia, e por fim decide aceitá-la. Ao passar pela cirurgia, vivencia incômodos, complicações, compreende que perdeu uma parte do corpo e procura conformar-se, tentando crer que foi o único caminho. As diversas mudanças que ocorrem fazem-na construir novos significados e mudar a percepção de si e do seu meio social, a partir da interação consigo mesma e com este meio, fazendo-a refletir sobre a sexualidade, seus relacionamentos, sua saúde, a diferença no corpo e em si mesma, nas funções que desempenha e sobre a mutilação provocada pela cirurgia. O desenvolvimento de mecanismos de enfrentamento, como comparar sua cirurgia e histórias com outras, identificar aprendizados com a experiência, buscar formas de superação e resignar-se resultaram na valorização da vida e na vontade de viver melhor. Percebe-se a importância da enfermeira estabelecer um cuidado multidimensional, que identifique as necessidades que vão além do corpo biológico, respeitando as particularidades e a individualidade no momento do cuidado e contribuindo para o bem-estar físico, psíquico, social e espiritual das mulheres.

Pulse NMR in solids : chemical shift, lead fluoride and thorium hydride

Part one of this thesis consists of two sections. In the first section the fluorine chemical shift of a single crystal CaF_2 has been measured as a function of external pressure up to 4 kilobar at room temperature using multiple pulse NMR techniques. The pressure dependence of the shift is found to be -1.7 ± 1 ppm/kbar, while a theoretical calculation using an overlap model predicts a shift of -0.46 ppm/kbar. In the second section a separation of the chemical shift tensor into physically meaningful "geometrical" and "chemical" contributions is presented and a comparison of the proposed model calculations with recently reported data on hydroxyl proton chemical shift tensors demonstrates, that for this system, the geometrical portion accounts for the qualitative features of the measured tensors.

Part two of the thesis consists of a study of fluoride ion motion in β-PbF_2 doped with NaF by measurement of the ^(19)F transverse relaxation time (T_2), spin lattice relaxation time (T_1) and the spin lattice relaxation time in the rotating frame (T_(1r)). Measurements over the temperature range of -50°C to 160°C lead to activation energies for T_1, T_(1r) and T_2 of 0.205 ± 0.01, 0.29 + 0.02 and 0.27 ± 0.01 ev/ion, and a T_(1r) minimum at 56°C yields a correlation time of 0.74 μsec. Pressure dependence of T_1 and T_2 yields activation volumes of <0.2 cm^3/g-mole and 1.76 ± 0.05 cm^3/g-mole respectively. These data along with the measured magnetic field independence of T_1 suggest that the measured T_1's are not caused by ^(19)F motion, but by thermally excited carriers.

Part three of the thesis consists of a study of two samples of Th_4H_(15), prepared under different conditions but both having the proper ratio of H/Th (to within 1%). The structure of the Th_4H_(15) as suggested by X-ray measurements is confirmed through a moment analysis of the rigid lattice line shape. T_1 and T_2 measurements above 390 K furnish activation energies of 16.3 ± 1.2 kcal/mole and 18.0 ± 3.0 kcal/mole, respectively. Below 350 K, T_(1r) measurements furnish an activation energy of 10.9 ± 0.7 kcal/mole, indicating most probably more than a single mechanism for proton motion. A time-temperature hysteresis effect of the proton motion was found in one of the two samples and is strongly indicative of a phase change. T_1 at room temperature and below is dominated by relaxation due to conduction electrons with the product T_1T being 180 ± 10 K-sec. Using multiple pulse techniques to greatly reduce homonuclear dipolar broadening, a temperature-dependent line shift was observed, and the chemical shift anisotropy is estimated to be less than 16 ppm.

Superconductivity, spin-glass properties, and ferromagnetism in amorphous La-Gd-Au alloys

The superconducting and magnetic properties of splat cooled amorphous alloys of composition (La_100-xGd_x)₈₀Au₂₀ (0 ≤ x ≤ 100) have been studied. The La₈₀Au₂₀ alloys are ideal type II super-conductors (critical temperature T_c = 3.5° K ). The concentration range (x less than 1) where superconductivity and spin-glass freezing n1ight coexist has been studied in detail. The spin-glass alloys (0 less than x less than 70) exhibit susceptibility maxima and thermomagnetic history effects. In the absence of complications due to crystal field and enhanced matrix effects, a phenomenological model is proposed in which the magnetic clusters are treated as single spin entities interacting via random forces using the molecular field approach. The fundamental parameters (such as the strength of the forces and the size of clusters) can be deduced from magnetization measurements. The remanent magnetization is shown to arise from an interplay of the RKKY and dipolar forces. Magnetoresistivity results are found to be consistent with the aforementioned picture. The nature of magnetic interactions in an amorphous matrix is also discussed. The moment per Gd atom (7µ_B) is found to be constant and close to that of the crystalline value throughout the concentration range investigated. Finally, a detail study is made of the critical phenomena and magnetic properties of the amorphous ferromagnet: Gd₈₀Au₂₀. The results are compared with recent theories on amorphous magnetism.

Densidade, genética e saúde populacional como ferramentas para propor um plano de controle e erradicação de invasão biológica: o caso de Callithrix aurita (Primates) no Parque Nacional da Serra dos Órgãos, RJ, Brasil

A introdução de espécies em locais fora de sua distribuição natural é uma preocupação importante na conservação da biodiversidade. A espécie Callithrix aurita é endêmica das regiões de floresta de altitude da Mata Atlântica do Sudeste do Brasil. Os critérios mais relevantes que a enquadram como espécie ameaçada de extinção são: destruição do habitat, incapacidade de adaptação a florestas secundárias degradadas, declínio populacional, distribuição restrita e introdução de espécies exóticas invasoras. Estes critérios, aliados à evidente raridade, explicam a sua inclusão na Lista Oficial de Espécies da Fauna Brasileira Ameaçadas de Extinção. Os objetivos do trabalho são: estimar o tamanho populacional de C. aurita, C. penicillata e seus híbridos no Parque Nacional da Serra dos Órgãos, avaliar a hibridação entre as espécies por caracteres morfológicos e laboratoriais, verificar o estado de saúde e confirmar a participação de C. aurita na paternidade dos animais capturados, propor um plano de erradicação e de controle de invasão de C. penicillata no Parque. Os tamanhos populacionais das duas espécies de primatas foram estimados através do método Distance Sampling. Um total de sete sagüis foi capturado com armadilhas de captura viva para a contenção física e química e posterior realização dos procedimentos. Para o hemograma, as dosagens bioquímicas e as análises genéticas, o sangue foi recolhido em um tubo de ensaio contendo anticoagulante e mantido em temperatura de refrigeração até o momento da manipulação / processamento das amostras. Callithrix aurita parece estar bem preservada apenas na área do Parque correspondente ao trecho situado no município de Petrópolis. As análises citogenéticas e moleculares dos híbridos são uma ferramenta útil para confirmar se há ou não hibridação, identificando as espécies envolvidas e verificando se há tendência nos retrocruzamentos. Pode-se sugerir que existe uma tendência à diferenciação das espécies e identificação de indivíduos híbridos pelo padrão hematológico e bioquímico, a ser confirmada com uma amostragem maior de animais da espécie C. aurita, preferencialmente da mesma localidade e nas mesmas condições. No caso de C. aurita, as principais recomendações para sua conservação incluem pesquisas para o registro de outras populações em áreas de distribuição livres de invasão, para que se possa avaliar as chances de recuperação populacional e sobrevivência da espécie. A criação de novas Unidades de Conservação deve ser estimulada, assim como estudos mais aprofundados sobre a espécie nos locais já conhecidos de ocorrência, além de um programa seguro de criação em cativeiro.

Em busca do convívio social: o regime semi-aberto no Instituto Penal Oscar Stevenson

O presente trabalho tem como objetivo central analisar o Sistema Penitenciário do Estado do Rio de Janeiro a partir do regime semi-aberto, tendo como campo de análise o Instituto Penal Oscar Stevenson, situado em Benfica, no município do Rio de Janeiro, voltado para um público carcerário feminino. Buscou-se verificar, sob o enfoque das presas, a expectativa e possibilidades de retorno ao convívio social; analisar os aspectos jurídico-institucionais referentes ao regime semi-aberto, no que tange a obtenção dos benefícios, junto a Lei de Execução Penal e identificar quais as parcerias que viabilizam a inserção delas no mercado de trabalho. Para a efetivação desse trabalho utilizou-se, preferencialmente os pressupostos teóricos e metodológicos da pesquisa quali-quantitativa, pois foi trabalhado não só no nível da objetividade, mas também no significado das ações e relações humanas, sabendo que a realidade prisional é perpassada por questões de cunho opressor, punitivo, em função de preconizar a segurança. Foram realizados também levantamentos de dados bibliográficos e censitários, bem como entrevistas semi-estruturadas junto aos agentes penitenciários do setor de educação e classificação e principalmente as presas. A análise do material coletado permitiu confirmar as hipóteses da pesquisa: i) que a ausência de oportunidades que garantam às presas os benefícios do regime semi-aberto não se dá por falta de instrumentos legais, mas sim pela burocracia no cadastramento e poucas parcerias de cursos profissionalizantes, empresas privadas que absorvam mão-de-obra das presas do regime semi-aberto; e ii) e que no momento em que as presas ainda estavam no regime fechado, não tiveram oportunidades de se capacitarem e também os vínculos familiares não foram mantidos, com isso dificultando que estas usufruam dos benefícios do regime semi-aberto. E, conseqüentemente, sendo cada vez mais adiado o seu retorno gradativo ao convívio social, através da progressão de regime.
