Abstract:

A dissertação propõe-se a compreender qual o panorama arquitectónico em que se enquadram as duas obras de Oscar Niemeyer e Paulo Mendes da Rocha em Portugal, respectivamente o Casino Park Hotel (1966-1976/79) e o novo Museu Nacional dos Coches (2008 - em construção). A distância cronológica de cerca de quatro décadas entre a realização dos projectos, as únicas obras construídas de dois grandes arquitectos brasileiros no país, conduz a algumas questões às quais se pretende obter resposta com o desenvolvimento do trabalho. Porquê que entre a sua execução decorre esse largo espaço de tempo? Quais os motivos que conduzem ao hiato? Como se definia o panorama arquitectónico português durante a realização dos dois projectos? Qual o contributo dessas obras? Em que pontos se aproximam? O estudo foca assim sobre a relação da arquitectura moderna brasileira e o seu contributo para a arquitectura portuguesa e as causas que conduzem ao desaparecimento dessa aproximação, assim como a conjuntura da arquitectura moderna brasileira; ABSTRACT: The paper proposes to understand what is the architectonic panorama in which the two works of Oscar Niemeyer and Paulo Mendes da Rocha in Portugal fit, respectively Casino Park Hotel (1966-1976/79) and the new National Coach Museum (2008 - under construction). The chronological distance of about four decades between the projects’ completion, the only constructed works of two great Brazilian architects in the country, leads to some questions to which the paper intends to respond. Why between its executions, elapses that large time? What are the reasons that lead to the gap? How was the Portuguese architectonic panorama defined during the two projects’ accomplishment? What is the contribution of these works? On what points they draw near each other? The study focuses on the relation of modern Brazilian architecture, its contribution to Portuguese architecture and the causes that lead to the disappearance of this approach, as well as the conjuncture of modern Brazilian architecture.

Abstract:

One of the salient features of the human cochlea is the incredible dynamic range it possesses—the loudest bearable sound is 10,000,000 times greater than the softest detectable sound; this is in part due to an active process. More than twelve thousand hairlike cells known as outer hair cells are believed to expand and contract in time to amplify cochlear motions. However, the cochlea’s response is more than just the sum of its parts: the local properties of outer hair cells can have unexpected consequences for the global behaviour of the system. One such consequence is the existence of otoacoustic emissions (OAEs), sounds that (sometimes spontaneously!) propagate out of the cochlea to be detected in the ear canal. In this doctoral thesis, a classical, lumped-element model is used to study the cochlea and to simulate click-evoked and spontaneous OAEs. The original parameter values describing the microscopic structures of the cochlea are re-tuned to match several key features of the cochlear response in humans. The frequency domain model is also recast in a formulation known as state space; this permits the calculation of linear instabilities given random perturbations in the cochlea which are predicted to produce spontaneous OAEs. The averaged stability results of an ensemble of randomly perturbed models have been published in [(2008) ‘Statistics of instabilities in a state space model of the human cochlea,’ J. Acoust. Soc. Am. 124(2), 1068-1079]. These findings support one of the prevailing theories of SOAE generation. Nonlinear simulations of OAEs and the model’s response to various stimuli are performed in the time domain. Features observed in the model include the saturation of the forces generated by the OHCs, compression of amplitude growth with increasing stimulus level, harmonic and intermodulation distortion, limit cycle oscillations that travel along the cochlear membranes, and the mutual suppression of nearby linear instabilities.

Abstract:

[Truncated abstract] The cochlea presumably possesses a number of regulatory mechanisms to maintain cochlear sensitivity in the face of disturbances to its function. Evidence for such mechanisms can be found in the time-course of the recovery of CAP thresholds during experimental manipulations, and in observations of slow oscillations in cochlear micromechanics following exposure to low-frequency tones (the “bounce phenomenon”) and other perturbations. To increase our understanding of these oscillatory processes within the cochlea, and OHCs in particular, investigations into cochlear regulation were carried out using a combination of mathematical modelling of the ionic and mechanical interactions likely to exist within the OHCs, and electrophysiological experiments conducted in guinea pigs. The electrophysiological experiments consisted of electrocochleographic recordings and, in some cases, measurement of otoacoustic emissions, during a variety of experimental perturbations, including the application of force to the cochlear wall, exposure to very-low-frequency tones, injection of direct current into scala tympani, and intracochlear perfusions of artificial perilymph containing altered concentrations of potassium, sodium, and sucrose. To obtain a panoramic view of cochlear regulation under these conditions, software was written to enable the interleaved and near-simultaneous measurement of multiple indicators of cochlear function, including the compound action potential (CAP) threshold, amplitude and waveshape at multiple frequencies, the OHC transfer curves derived from low-frequency cochlear microphonic (CM) waveforms, distortion-product otoacoustic emissions (DPOAEs), the spectrum of the round-window neural noise (SNN), and the endocochlear potential (EP). ... The mathematical model we have developed provided a physiologically-plausible and internally-consistent explanation for the time-courses of the cochlear changes observed during a number of different perturbations. We show that much of the oscillatory behaviour within the cochlea is consistent with underlying oscillations in cytosolic calcium concentration. We conclude that a number of the discrepancies between the simulation results and the experimental data can be resolved if the cytosolic calcium functions as two distinct pools: one which controls basolateral permeability and one which controls slow motility. This two-calcium-pool model is discussed.

Abstract:

The morphological study of the Odontocete organ of Corti including possible pathological features resulting from sound over-exposure, represent a key conservation issue to assess the effects of acoustic pollution on marine ecosystems. Through the collaboration with stranding networks belonging to 26 countries, 150 ears from 13 species of Odontocetes were processed. In this dissertation, we present a standard protocol to 1) compare the ultrastructure of the cochlea in several Odontocete species and 2) investigate possible damage as a consequence of sound exposure, using scanning (SEM) and transmission (TEM) electron microscopy, and immunohistochemistry. In a preliminary study, computerized tomography scans were performed before decalcification with ears of 15 odontocete species, proposing a set of standard measurements which classified very well the species. In addition, the constant ratio between measurements of inner and middle ear structures contributed to confirm the active role of the odontocete middle ear in sound reception mechanism. We established a decalcification protocol using the fast commercial decalcifier RDO® and EDTA (Ethylendiaminetetraacetic acid). Although further experiments should be conducted to assess the suitability of using one or the other method (because the number of samples treated with EDTA was comparatively small), RDO® at specific dilutions decreased the decalcification time of cetacean ear bones with control of the decalcification endpoint, helping a faster access to inner structures. The complementary use of electron microscopy and immunofluorescence allowed the description in odontocetes of new morphological features of tectorial membrane, spiral limbus, spiral ligament, stria vascularis, hair cells and their innervation. Furthermore, this study revealed qualitative and quantitative morphological characteristics of the organ of Corti in high-frequency hearing species, including 1) an outer hair cell (OHC) small length, 2) a thick cuticular plate in OHC, and a thick reticular lamina, 3) robust cup formation of the Deiters cell body, 4) the high development of cytoskeleton in Deiters and pillar cells and 5) the basilar membrane high stiffness. Interestingly, all these features, including a common molecular design of prestin, are also shared by echolocating bats, suggesting a convergent evolution in echolocating species. The presence of scars among hair cell rows, the pattern of stereocilia imprints in the tectorial membrane and the condition of fibrocytes II and IV were criteria suitable to determine or discard possible acoustic trauma, despite the numerous artefacts that rapidly develop as a consequence of tissue autolysis. Consequently, matching the preliminary approximation of the cochlear frequency map with the damaged region would bring information on the sound source that would have triggered a possible lesion.

Abstract:

The cochlea is an organ which extracts frequency information from the input sound wave. It also produces nerve signals, which are further analysed by the brain and ultimately lead to perception of the sound. An existing model of the cochlea by Fragni`ere is first analysed by simulation. This passive model is found to have the properties that the living cochlea does in terms of the frequency response. An analog VLSI circuit implementation of this cochlear model in CMOS weak inversion is proposed, using log-domain filters in current domain. It is fabricated on a chip and a measurement of a basilar membrane section is performed. The measurement shows a reasonable agreement to the model. However, the circuit is found to have a problem related to transistor mismatch, causing different behaviour in identical circuit blocks. An active cochlear model is proposed to overcome this problem. The model incorporates the effect of the outer hair cells in the living cochlea, which controls the quality factor of the basilar membrane filters. The outer hair cells are incorporated as an extra voltage source in series with the basilar membrane resonator. Its value saturates as the input signal becomes larger, making the behaviour rather closer to that of a passive model. The simulation results show this nonlinear phenomenon, which is also seen in the living cochlea. The contribution of this thesis is summarised as follows: a) the first CMOS weak inversion current domain basilar membrane resonator is designed and fabricated, and b) the first active two-dimensional cochlear model for analog VLSI implementation is developed.

Abstract:

The auditory system has a wide dynamic range and remarkable selectivity, due partly to the nonlinear processing within the cochlea. Modelling the performance of the cochlea is a way to gain insight into how it operates and to better understand its mechanical structure, whose arrangement generates nonlinear phenomena. A box model with nonlinear micromechanics was simulated using the state space method and the quasi-linear method to understand nonlinear dynamic interactions within the cochlea. The results from the quasi-linear model were essential for obtaining cochlear compression curves, which were used to tune the saturation parameters of the nonlinear function incorporated into the state space model. The nonlinear state space model allows time domain simulations to be performed that can replicate spontaneous otoacoustic emissions (SOAEs); sounds that can be measured in the ear canal, which are generated inside the cochlea and are by-products of the nonlinear process of the cochlear amplifier. The time domain model was mathematically formulated to reduce the computational load, which has previously limited the number of results that could be obtained. A novel method of incorporating initial conditions into the state space model has also been developed. Time domain simulations illustrate how SOAEs are due to limit cycle oscillations, whose amplitude is controlled by the saturation of the cochlea's amplification process. The results support the standing wave theory, whereby the emissions are produced by the reflection from random perturbations along the length of the cochlear partition at one end and the stapes at the other. Simulations of the interaction between a SOAE and low frequency bias tones give results that are comparable with those produced experimentally, but allow a greater physical interpretation. Simulations are also performed of the interaction between a SOAE and other stimuli, such as a swept tone that sweeps through the frequency of the emission and a high-level, low-frequency tone.

Abstract:

Ten varieties of oats were grown in a trial to test grain yield. Five of the varieties produced more than 4,000 pounds per acre; the top - yielding variety, Ogle, from Minnesota, produced 4,578 pounds per acre. Difficulties in establishing a perfect stand with the small plot grain drill would probably mean that a farmer could expect yields higher than these when using full -sized equipment. Considering the premium for oats, oats for grain could be a viable alternative crop.

Seven New Mexico acala varieties and one non-acala short staple variety were evaluated for yield and other agronomic variables. 1517-88 produced the most seed cotton but HS 46, the non-acala produced slightly more lint. Both varieties yielded slightly less than three bales of lint per acre. Yields of most of the varieties in the trial were 100 to 200 pounds less than in the previous year. It is felt that the yield reductions were probably more due to lack of heat units during the growing season than the heat spell in June.

Abstract:

The cochlea plays an important role in human hearing. Its basic function is to map sounds of different frequencies onto corresponding characteristic positions on the basilar membrane, BM. When sounds enter the fluid-filled cochlea, deflections of the BM occur due to pressure differences between the cochlear fluid chambers. These deflections propagate along the cochlea to a frequency-dependent characteristic position and then decay away rapidly. The mechanics of the cochlea are modelled using both analytic and numerical models. In this thesis, the passive response of the cochlea is analysed, corresponding to its behaviour at high sound levels, to study the fluid coupling and waves in the cochlea. The fluid coupling is studied in 1D and 3D, uniform and non-uniform, uncoiled and coiled geometries, all with a passive basilar membrane. A ‘uniaxial model’, which is dependent on only a single dimension, is developed to represent the three-dimensional cochlea. The finite element method is also used to provide an independent check of the results from the analytic model. Analytic methods are used to predict waves due to different mechanisms in the passive cochlea, such as 1D and 3D fluid coupling and longitudinal BM dynamics. The wave finite element, WFE, method is then used to decompose the results of a full finite element model of the coupled cochlea into wave components. Results show that apart from the conventional slow wave, other additional types of wave in the passive cochlea do not appear to play a dominant role in normal passive cochlear function.

Abstract:

Cette thèse s'attache à présenter le rôle d'un des artistes les plus influents dans la France du XVIIIe siècle, Charles-Nicolas Cochin, dit Cochin Fils (1715-1790). La première partie est consacrée à la place de Cochin dans la société de son temps. Issu d'une famille aux confins de l'artisanat, il devient, grâce à ses succès de dessinateur et de graveur et ses qualités sociales, le secrétaire de l'Académie de peinture et l'intermédiaire entre l'administration et les artistes. Son influence décroît à partir de 1770, mais il reste une personnalité importante jusqu'à sa mort. La seconde partie est consacrée aux théories artistiques de Cochin. Il s'efforce de transformer le discours traditionnel pour rendre compte de la création contemporaine. Sa réflexion, souvent critique, l'amène à proposer des projets pour rénover la peinture. La troisième partie étudie l'influence de Cochin sur la production artistique de son temps. Il ne peut mettre pleinement en application ses idées dans ses dessins. Il rencontre les mêmes difficultés dans ses tentatives d'aider ou de diriger les autres artistes en leur fournissant des modèles ou en leur faisant distribuer des encouragements par l'administration royale. Malgré de nombreux échecs, il a pourtant suscité des mutations importantes dans l'art de son temps
The aim of this dissertation is to illustrate the role of one of the most influencial artists in the Eighteenth Century France, Cochin. The first part is devoted to Cochin and the social life of his time. Coming from the middle-class, he became, thanks to his achievement as a draughman and an engraver, as well as to his social abilities, the secretary of the Royal Academy of Painting, and the go-between the royal administration and the artists. If his influence decrease after 1770, he remains nevertheless a major figure until he died. The second part is devoted to Cochin's theories in art. He tried to change the traditional shapes of the academic rhetoric in order to give an account of the contemporary art. Often critical, his thoughts lead him to propose some plans of change and improvement in the contemporary way of painting. The third part is a study of Cochin's influence over the artistic creation. His own kind of art forbids him to realize his ideas through his draughtmanship. Even when he tried to advise and help the other artist in giving them designs, as well providing them with financial or administrative supports, he did not fully succeed. Nevertheless Cochin's position and action remain crucial

Abstract:

The cochlea is a specialised structure that contains the cells responsible for transducing mechanical sound stimuli into neural code within the auditory nerve. Mutations in the mitochondrial genome have been associated with hearing loss, suggesting that they play a key role in cochlear physiology. Alongside ATP production, mitochondria are also intimately involved in processes such as calcium homeostasis and the regulation of cell death. The precise role for mitochondria in inner ear physiology is at present poorly defined. I used neonatal cochlear explants and confocal microscopy to study aspects of mitochondrial physiology. The dye TMRM was used to investigate differences in A j/mt between basal and apical inner (IHC) and outer (OHC) hair cells and supporting cells. Data reveal a base-to-apex difference in mitochondrial function specific to inner hair cells. Mitochondrial function was investigated further using the endogenous autofluorescence of NADH and flavoproteins and revealed a base-to-apex difference in cell redox state, again in the IHCs but not OHCs. Differences in intracellular metabolism were also investigated using fluorescence lifetime imaging of NAD(P)H and revealed metabolic differences between OHCs and supporting cells consistent with a metabolism that is more glycolytic in supporting cells and more oxidative in OHCs. 9+ The role of mitochondria in cochlear Ca homeostasis was also investigated. The amplitude and spatiotemporal properties of intercellular Ca waves initiated by ATP 9+ 9+ were studied. Blocking mitochondrial Ca ( Ca mt) uptake using Ru360 increased the wave amplitude, propagation velocity and extent of spread in cochlear supporting cells, 94- showing that mitochondrial Ca buffering plays a role in shaping calcium signals in the cochlea. 9+ 9+ Finally, neomycin was used to investigate Ca c and Ca mt during neomycin toxicity. 94- Neomycin induced a rapid bi-phasic response in OHC Ca c leading to cell loss of A /mt and cell permeabilsation, which correlated with ATP-dependent intercellular Ca waves in the surrounding supporting cells.

Abstract:

[Truncated abstract] One of the problems in researching tinnitus is that it has often been assumed that the physiological mechanisms underlying the tinnitus percept cannot be objectively measured. Nonetheless, it is generally accepted that the percept results from altered spontaneous neural activity at some site along the auditory pathway, although it is still debated whether it is produced by: synchronisation of activity of adjacent neurones; a change in the temporal pattern of activity of individual neurones; or an increase in the spontaneous firing rate per se. Similarly, it is possible that the recently coined “auditory neuropathy” is produced by under-firing of the primary afferent synapse, although several other mechanisms can also produce the symptoms described by this disorder (normal cochlear mechanical function but absent, or abnormal, synchronous neural firing arising from the cochlea and auditory brainstem, known as the auditory brainstem response, or ABR). Despite an absent ABR, some subjects can detect pure tones at near-normal levels, although their ability to integrate complex sounds, such as speech, is severely degraded in comparison with the pure-tone audiogram. The aim of the following study was to investigate the normal mechanisms underlying neural firing at the primary afferent synapse, and its regulation, to determine the possible mechanisms underlying over-firing (tinnitus) or under-firing (auditory neuropathy) of primary afferent neurones.

Abstract:

Variety trials were grown at two locations and with two different sets of short staple varieties. One trial on the Robbs farm, north of Kansas Settlement, tested two acala varieties and the most promising advanced strain from New Mexico, two short seasoned varieties from SureGrow and one Australia variety. The other trial on the Glenn Schmidt farm, in Kansas Settlement, tested seventeen upland varieties as part of the statewide testing program. The highest yielding variety in the Robbs trial was SG 404 with SG 125 coming in second. In the Schmidt trial, FM 989, an Australian variety that has performed well in Safford, had the highest yield, just over 2 bales per acre.

Abstract:

The Acala and Upland Variety trials typically grown in Cochise County were combined into one study in 1999 and were planted on the Glenn Schmidt farm, in Kansas Settlement. Twelve varieties were tested including three New Mexico Acalas and one Interspecific Hybrid from Israel. The highest yielding variety in the trial was FM 989 with a yield near 1200 pounds of lint. It was also the highest yielding variety in the Cochise County trial in 1998. PM 1560 BG came in a close second with the Israeli varity (Hazera 151-208) and the two New Mexico varieties (1517-95 and 1517-99) yielding over 1100 pounds of lint.

Abstract:

The 1987 trials included 14 commercial corn hybrids, which were tested on a heavy - textured soil in northern Cochise county; they were the better yielding hybrids from the previous trial. Five new entries, not previously tested in Cochise county, were included. Garst 8345, one of the new entries, was both the top - yielder, at 12,499 pounds per acre, and the hybrid producing the highest adjusted gross income per acre. Hybrids produced by Pioneer, Cargill, DeKalb and NC+ seed companies all yielded more than 12,000 pounds per acre.
