Circulação recente de sedimentos costeiros nas praias de santos durante eventos de tempestades: Dados para a gestão de impactos físicos costeiros

The beachs of Santos are situated in Santos Bay, central portion of paulista coast, in São Paulo state. This beachs are frequently affected by cold fronts with winds and currents from the South. These fronts are responsible for the removal and transport of sediments (sand) in Santos beaches. In order to quantify this sedimentation the channels of Santos were analysed, due to their function as box colectors of sediments during storm events. The channels are filled by sands, which volume in channels 1 to 6 was estimated, by using the length, width and height of sand sedimented in the channels, in the event of 22-27 april 2005. The chanels 2, 3 and 1 presented the larger volumes of sands, confirming that the central and SW portion of the beaches of Santos present higher levels of sedimentation or re-sedimentation. That is due to the transport by ocean waves and currents and currents from the Channel of the Port of Santos. This central portion suffer invasion of marine water over street and buildings, caracterizated of geological rise area.

Climatologia de tempestades na área central do Estado de São Paulo usando radar meteorológico

A climatological characterization of storm properties during two summer seasons, viz. 1998-1999 and 1999-2000, based on observations from the Bauru S-band Doppler radar, was obtained from the TITAN Software of the National Center for Atmospheric Research (Boulder, Co), implemented at IPMet. Parameters, such as mean volume, mean area, mean and maximum echo tops, mean and maximum reflectivity, as well as speed and direction of precipitating systems were determined using the reflectivity >25, 30 and 40 dBZ and a volume >30 km3 as thresholds for storm identification. For the first time, the spatial distributions of these parameters were determined in the central State of São Paulo, based on radar observations. It was found that some preferential areas, where most of the convective activity was concentrated during the study period, were located along the Tietê River. The mean maximum reflectivity field has highlighted preferential regions for convection to develop over the metropolitan area of Campinas, which in turn was reinforced by the distribution of the echo tops and reflectivity >40 dBZ.

Estado emocional de familiares de pacientes hospitalizados con alteraciones severas de la conciencia

Los pacientes hospitalizados con alteraciones severas de la conciencia (pacientes en estado vegetativo permanente o pacientes en estado de mínima conciencia) debido a su enfermedad neurológica, no tienen conciencia de si mismos ni pueden interactuar con su entorno; no tienen comprensión ni emiten lenguaje y no tienen conductas voluntarias. Esta presencia ausente del enfermo y el carácter irreversible e indefinido de la enfermedad, da lugar a que los familiares cuidadores afronten con dificultad el acompañamiento del paciente y la situación que se ven obligados a vivir, presentando un elevado riesgo de padecer malestar emocional. Es necesario investigar en nuestro país, el impacto emocional que causa en los familiares, acompañar a un paciente que padece una alteración severa de la conciencia y estudiar las variables predictoras e implicadas en el malestar emocional que sus familiares padecen...

Cuerpo y palabra en el abordaje psicoterapéutico de niños con dificultades severas de simbolización: terapia psicomotriz con intervenciones psicoanalíticas

Esta tesis tiene como objetivo fundamentar teóricamente desde el psicoanálisis y desde la experiencia clínica, el beneficio de un abordaje psicoterapéutico cuyo setting provea condiciones físicas y técnicas para el trabajo a partir del cuerpo y de los aspectos sensoriomotrices. Se dirige a niños con dificultades severas de simbolización: recursos muy precarios a nivel del lenguaje oral y el juego simbólico, que afecta sus posibilidades de comunicación social. El abordaje psicoterapéutico propuesto se basa en la idea de que para favorecer los procesos de simbolización el tratamiento debe seguir un trayecto del cuerpo al lenguaje. Consiste en el trabajo conjunto de un psicomotricista con un psicoanalista, creando un campo terapéutico común, aunando los recursos de ambas formas de tratamiento. La denominación de «Terapia Psicomotriz con Intervenciones Psicoanalíticas» da cuenta de que la técnica y el setting de la psicomotricidad (espacio, materiales, diálogo corporal) son esenciales, pero al mismo tiempo, con un posicionamiento clínico y una modalidad de intervención psicoanalíticos, donde el vínculo transferencial es fundamental. Otros objetivos son: (2) promover la reflexión sobre la necesidad de una inclusión mayor del trabajo con cuerpo en los abordajes psicoterapéuticos del niño, en proporción al grado en que sus procesos de simbolización están comprometidos, (3) investigar modalidades de interacción en el vínculo temprano en todos sus niveles y los procesos de simbolización que se generan en ellas (4) mostrar los beneficios de la interdisciplina, tanto teórica como clínica...

Estudos de distúrbios ionosféricos propagantes de larga escala (LSTID’S) na região equatorial durante grandes tempestades magnéticas: estudo de casos

The Ionospheric Disturbances – TIDs – are irregularities on the ionospheric plasma propagating in speeds in the order of tens to a few hundreds of meters per second. This present study detected and characterized the TIDs of LSTIDs (Large Scale Travelling Ionospheric Disturbance) type at low latitudes during intense geomagnetic storms and its propagation over the Brazilian sector. This work also shows as being the first to report systematically propagation of gravity waves over Natal. For this purpose, we used ionospheric records obtained from type of digisonde CADI (Canadiam Advanced Digital Ionosonde) located in Natal and the type DSP (Digisonde Portable Souder) located in Cachoeira Paulista, Fortaleza and São Luis, whereupon we used a dataset of 12 years collected by INPE (National Institute of Space Research). In this study, both calm days, that preceded the storms, and the geomagnetically disturbed days were related during the years 2000 and 1012, which cover a period of maximum and minimum solar activity. And it is presented the variations that happened in the electron density from region F of the ionosphere over the Brazilian sector, especially near the Equator (Natal, Fortaleza and São Luis), caused by ionospheric disturbances in the equatorial region during intense geomagnetic storms, because, as we know of the literature in this area, this phenomenon contributes positively to the emergence of LSTIDs in the auroral region, which may move to the equatorial region where a few cases have been documented and studied systematically. From the observation of signatures if TIDs in ionogram records, a study of the morphology of these events was performed and compared with the main characteristics of the wave of this phenomenon during great magnetic storms, i.e., DST <(-200 nT) and KP > 6. Thus, we obtained the main characteristics of TIDs over our region, i.e., period, vertical wavelength, phase and propagation speed, as well as the delay of these disturbances compared to the beginning of the magnetic storms to the Brazilian Sector.

Estudo da variabilidade da deriva vertical do plasma ionosférico sobre a região de Natal/RN, Fortaleza/CE e Cachoeira Paulista/SP para alguns casos de tempestades magnéticas de abril a setembro de 2000

In this work are presented the results of research on the variation of vertical plasma drift from the F layer that commonly occurs during the period close to the going down of the sun (between 21UT - 22UT), and consisting of an increase in the F layer in time of day and a drop at night on the cities of Natal / RN (The 33.7º, 5.6º S), Fortaleza / CE (38.45º O, 3.9º S) and Cachoeira Paulista / SP (45.0ºO, 22.7º S ). Thus, data was used (ionograms) virtual height t ( h' ) as a function of the frequency F for the layer of the ionosphere. These data were collected through ionossonda type CADI (Canadian Advanced Digital Ionosonde) to the cities of Natal and Fortaleza, and the Digisonde DPS to the town of Cachoeira Paulista. They considered only the data available 2000 maximum solar year. With the virtual height ( h' ) data reduced in the frequencies of 6MHz and 5MHz, the next step was to calculate. The results showed that the variability of the vertical drift rate F ionospheric layer periods of magnetic storms is related both to the penetration of the electric fields as the disturbance dynamo electric fields.
