Sofrimento e Adaptação: Aspectos Sociais e Psico-afetivos de Pacientes com Doença Periodontal Crônica

OS OBJETIVOS DESTE ESTUDO FORAM: CARACTERIZAR A POPULAÇÃO DE PACIENTES DE UMA CLÍNICA-ESCOLA; INVESTIGAR OS ASPECTOS PSICO-AFETIVOS ASSOCIADOS ÀS DOENÇAS PERIODONTAIS DESSES PACIENTES, ALÉM DOS RECURSOS DEFENSIVOS UTILIZADOS POR ELES. MÉTODO: LEVANTOU-SE DADOS SÓCIO-DEMOGRÁFICOS, DE SAÚDE GERAL E PERIODONTAL DE 789 PACIENTES ATENDIDOS NUM DEPARTAMENTO DE PERIODONTIA DE UMA CLÍNICA-ESCOLA DE ODONTOLOGIA, DADOS ESTES QUE CONSTITUÍRAM A ETAPA QUANTITATIVA DO ESTUDO. ESSA CARACTERIZAÇÃO FOI FEITA ATRAVÉS DE PLANILHAS ESPECIALMENTE ELABORADAS PARA A PESQUISA. A PARTIR DESSAS PLANILHAS, FOI SELECIONADA UMA SUB-AMOSTRA DE 273 PACIENTES QUE APRESENTARAM QUEIXAS EM TRÊS OU MAIS SISTEMAS ORGÂNICOS, ALÉM DA QUEIXA PERIODONTAL, OS QUAIS FORAM DENOMINADOS DE PACIENTES POLI-QUEIXOSOS. UMA TERCEIRA SUB-AMOSTRA INTEGROU 59 PACIENTES POLI-QUEIXOSOS, DIAGNOSTICADOS COM DOENÇA LEVE A MODERADA OU LEVE A SEVERA. DESSES PACIENTES, TRÊS FORAM ENTREVISTADOS E INTEGRARAM A AMOSTRA DA ETAPA QUALITATIVA DA PESQUISA. OS RESULTADOS INDICARAM QUE ENTRE PACIENTES POLI-QUEIXOSOS NÃO FOI ENCONTRADA CORRELAÇÃO SIGNIFICATIVA ENTRE DOENÇA PERIODONTAL LEVE A MODERADA OU LEVE A SEVERA COM GÊNERO, IDADE, ESTADO CIVIL, GRAU DE INSTRUÇÃO OU ATIVIDADE LABORAL. TAMBÉM NÃO HOUVE RELAÇÃO SIGNIFICATIVA QUANTO À PRESENÇA DE TABAGISMO, BRUXISMO, ONICOFAGIA E XEROSTOMIA. VERIFICAMOS QUE A DOENÇA PERIODONTAL CRÔNICA TEM SUAS ORIGENS NAS RELAÇÕES OBJETAIS DA MAIS TENRA INFÂNCIA E QUE AS ANSIEDADES ESQUIZO-PARANÓIDES QUE CARACTERIZAM ESSAS PRIMEIRAS RELAÇÕES, CONTINUAM PERMEANDO AS RELAÇÕES DURANTE TODA A VIDA DAS PACIENTES. COMO OS RECURSOS DEFENSIVOS UTILIZADOS SÃO PSIQUICAMENTE POUCO EVOLUÍDOS, O EQUILÍBRIO, A HOMEOSTASE É ENCONTRADA NA DOENÇA. CONCLUÍMOS QUE A DINÂMICA INTRA-PSÍQUICA PODE ESTAR ASSOCIADA NÃO SÓ À DOENÇA PERIODONTAL, MAS TAMBÉM AO ESTADO DE SAÚDE GERAL DESSES PACIENTES.

An inter-laboratory validation of methods of lipid peroxidation measurement in UVA-treated human plasma samples

Lipid peroxidation products like malondialdehyde, 4-hydroxynonenal and F(2)-isoprostanes are widely used as markers of oxidative stress in vitro and in vivo. This study reports the results of a multi-laboratory validation study by COST Action B35 to assess inter-laboratory and intra-laboratory variation in the measurement of lipid peroxidation. Human plasma samples were exposed to UVA irradiation at different doses (0, 15 J, 20 J), encoded and shipped to 15 laboratories, where analyses of malondialdehyde, 4-hydroxynonenal and isoprostanes were conducted. The results demonstrate a low within-day-variation and a good correlation of results observed on two different days. However, high coefficients of variation were observed between the laboratories. Malondialdehyde determined by HPLC was found to be the most sensitive and reproducible lipid peroxidation product in plasma upon UVA treatment. It is concluded that measurement of malondialdehyde by HPLC has good analytical validity for inter-laboratory studies on lipid peroxidation in human EDTA-plasma samples, although it is acknowledged that this may not translate to biological validity.

Dispersion engineering of highly nonlinear chalcogenide suspended-core fibers

Chalcogenide optical fibers are currently undergoing intensive investigation with the aim of exploiting the excellent glass transmission and nonlinear characteristics in the near- and mid-infrared for several applications. Further enhancement of these properties can be obtained, for a particular application, with optical fibers specifically designed that are capable of providing low effective area together with a properly tailored dispersion, matching the characteristics of the laser sources used to excite nonlinear effects. Suspended-core photonic crystal fibers are ideal candidates for nonlinear applications, providing small-core waveguides with large index contrast and tunable dispersion. In this paper, the dispersion properties of As2S3 suspended-core fibers are numerically analyzed, taking into account, for the first time, all the structural parameters, including the size and the number of the glass bridges. The results show that a proper design of the cladding struts can be exploited to significantly change the fiber properties, altering the maximum value of the dispersion parameter and shifting the zero-dispersion wavelengths over a range of 400 nm.

Chalcogenide suspended-core fibers for supercontinuum generation in the mid-infrared

Chalcogenide suspended core fibers are a valuable solution to obtain supercontinuum generation of light in the mid-infrared, thanks to glass high transparency, high index contrast, small core diameter and widely-tunable dispersion. In this work the dispersion and nonlinear properties of several chalcogenide suspended core mi-crostructured fibers are numerically evaluated, and the effects of all the structural parameters are investigated. Optimization of the design is carried out to provide a fiber suitable for wide-band supercontinuum generation in the mid-infrared.

Highly nonlinear chalcogenide suspended-core fibers for applications in the mid-infrared

Due to their unique dispersion and nonlinear properties, chalcogenide suspended-core fibers, characterized by a few micrometer-sized core suspended between large air-holes by few small glaß struts, are excellent candidates for mid-infrared applications. In the present study the influence of the main croß-section characteristics of the chalcogenide suspended-core fibers on the dispersion curve and on the position of the zero-dispersion wavelength has been thoroughly analyzed with a full-vector modal solver based on the finite element. In particular, the design of suspended-core fibers made of both As2S3 and As2Se3 has been optimized to obtain dispersion properties suitable for the supercontinuum generation in the mid-infrared.

Análise estratigráfica de subsuperfície do Devoniano Inferior da Bacia do Rio do Peixe, Nordeste do Brasil

Subsurface stratigraphic analysis of Devonian strata from the Rio do Peixe Basin, newly recognized by palynological studies, has resulted in the identification of two new lithostratigraphic units assembled in the Santa Helena Group. The Pilões Formation, the lower unit, is composed mainly of dark mudstones and medium-tovery fine-grained sandstones, with minor conglomerates and breccias. The Triunfo Formation, the upper unit, comprises whitish grey, kaolinitic, coarse-grained to conglomeratic, cross stratified sandstones and conglomerates, with interbedded mudstones and fine-grained sandstones. These units were characterized using cores, sidewall and cuttings samples, conventional logs and image log, from three wells drilled by PETROBRAS, and 3D seismic data. The Pilões Formation is interpreted as prodeltaic facies, with lesser associated subaqueous talus, debrite and sandy turbidite lobe facies, distal part of fandelta and braided fluviodeltaic facies of Triunfo Formation. The Santa Helena Group corresponds to the Lower Devonian tectono-sequence deposited in a NW-SE-trending graben during a transgressiveregressive cycle. With 343 meters of thickness (isochore) in well 1-PIL-1-PB (Pilões 1), this sequence has a non-conformity at the lower boundary and its upper boundary is an unconformity with the Lower Cretaceous tectono-sequence (Rio do Peixe Group), that represents a hiatus of about 265 million years. Ignimbrites and coignimbrite breccias (Poço da Jurema volcanic breccia), related to an unknown pyroclastic volcanic event, were recognized at the northern margin of the Sousa halfgraben. Evidence from well data suggests that this event is coeval with the Devonian graben filling. The present study indicates a polyhistorical tectono-volcanosedimentary evolution of the basin. This lithostratigraphic update brings new perspectives for geological research in the Rio do Peixe Basin, as well as in other inland basins of the Northeastern of Brazil. The results of the research also contribute to the kwnoledge of the Borborema Province and western Gondwana paleogeography during the Early Devonian.

Da maniva ao grolado: práticas produtivas e patrimoniais no processo identitário dos Tremembé de Almofala (CE)

The indigenous political scene in Brazil is undergoing transformations that need to be better analyzed by scholars in the field of the Social Sciences. The deficit in the policy of indigenous land demarcation emerges as the largest obstacle in the conquest of collective rights. Therefore, a study to analyze renewed strategies in the struggle for social rights, and their implications in local everyday life relations, is urgent. In this context, the aim of this research is to understand the current social dynamics of identity among the Tremembé people of Almofala, in the state of Ceará, Brazil, with a fieldwork conducted in the flour mill of the Casa de Farinha Comunitária project, in the Lameirão community. Specific aims are: a) to analyze the processes involved in the project in order to comprehend their meanings and appropriations as well as their everyday life and political uses; b) understand the strategies to fight for social benefits; c) analyze the local ethnic classifications grounding the construction of the Tremembé identity in Almofala. Methods deployed are ethnography of communities, used to apprehend the social production of networks of relationships, and a social cartography of practices. The realization of rights demanded by the indigenous populations in Brazil is intertwined with a process of social and legal legitimation their identity and cultural heritage. Such legitimation works as a safeguard mechanism of rights secured by the Constitution. Therefore, to own a “cultural heritage” is perceived as a “passport” to benefit from emerging rights. Amid this context, changes in the traditional processing of the cassava root, a productive practice shared locally by diverse social groups, is reified as cultural heritage by the Tremembé people of Almofala and their network of collaborators in the pursuit of accessing distinctive public policies. Furthermore, the research came across specific social arrangements of local subjects which unfolded internal struggles, enabling to understand the dynamics of the Tremembé of Almofala identity process.

Risorse idriche sotterranee del continente africano: disponibilità e prospettive di gestione

L’acqua è uno dei principali fattori per la crescita socio-economica e lo sviluppo del continente africano. Il continente africano dispone di ingenti risorse idriche, ma le complessità naturali caratteristiche di alcune regioni del continente e la frequente assenza di una corretta pianificazione della loro gestione ne riduce ad oggi il potenziale in maniera significativa. L’utilizzo delle risorse idriche in Africa è destinato ad incrementare sensibilmente nel corso dei prossimi decenni, come risultato della crescita demografica e dei fabbisogni nell’agricoltura. Le risorse idriche sotterranee giocano un importante ruolo in tale scenario in quanto molti paesi africani caratterizzati da scarsità d’acqua dispongono di sostanziali riserve idriche sotterranee e l’accesso a tali risorse, ancorché limitate, è largamente diffuso nel continente. Si stima che il totale delle risorse idriche sotterranee sia di 0,66 milioni di km cubi. Le risorse sotterranee sono largamente distribuite: i maggiori volumi sono localizzati nei larghi acquiferi sedimentari nelle regioni del nord Africa. Per molti paesi africani pozzi appropriatamente ubicati sono in grado di sostenere le comunità con l’estrazione manuale mediante pompe con una portata di 0,1-0,3 l/s. Grandi impianti di produzione da acquifero (>5 l/s), che siano adatti per lo sviluppo urbano o produzioni agricole intensive, non sono ancora diffusi e sono limitati ad aree particolari. La disponibilità ed accessibilità delle acque sotterranee in gran parte dell’Africa è favorevole ad uno sviluppo rurale piuttosto che urbano. Il maggiore fattore limitante per una gestione sostenibile delle risorse sotterranee è dato dalla necessità di identificare se le acque sotterranee sono rinnovabili (ed in quale misura) o meno, al fine di programmare le corrette politiche gestionali nel tempo.

Sistemi di protezione per i guasti verso terra

Con questa tesi di laurea si vogliono analizzare le possibili cause e motivazioni e le molteplici soluzioni di fenomeni presenti sia in ambito domestico sia in ambito industriale e riguardanti i sistemi di protezione per i guasti verso terra. Le problematiche analizzate, come si vedrà, sono sempre più tematiche di attualità e questo a causa del sempre maggiore utilizzo di elettronica di potenza, convertitori, inverter, computer e controlli elettronici in generale. Se da un lato questi carichi sono sempre più sensibili ad interruzioni o anomalie nella tensione ai loro capi, d’altro canto spesso essi stessi sono tra i colpevoli delle anomalie stesse. In un primo momento si vedrà un fenomeno molto comune e conosciuto che è lo scatto intempestivo del differenziale che può causare danni di una certa entità. In una seconda parte saranno poi analizzate altre problematicità legate all’interruttore differenziale ed ai sistemi di terra, in particolare per quanto riguarda il loro funzionamento nel caso di correnti di guasto non perfettamente sinusoidali o totalmente non sinusoidali. La non sinusoidalità, originata prevalentemente dai carichi non lineari, oltre a dare le problematiche ben conosciute sia a livello di rete sia a livello dei carichi collegati (aumenti delle perdite, malfunzionamenti, sovraccarico del conduttore di neutro) dà distorsione della corrente (in questo caso di quella di guasto a terra) modificando sia il comportamento del differenziale in caso di guasto (ad esempio mancato intervento dell’interruttore con i conseguenti pericoli per l’essere umano) sia le curve di sicurezza. Per procedere ad un’analisi più dettagliata delle non idealità nel funzionamento nell’interruttore automatico differenziale (sia per quanto riguarda lo scatto intempestivo sia per quanto riguarda altre problematiche) è necessario conoscerne in maniera adeguata sia la struttura sia il principio di funzionamento ed anche le diverse tipologie esistenti sul mercato.

El dinero en la historia del pensamiento económico: la teoría monetaria postkeynesiana y su confrontación con la ortodoxia

Las disputas en torno a determinados aspectos del dinero, como su neutralidad y el carácter endógeno o exógeno de la oferta monetaria, han sido permanentes entre las distintas escuelas de pensamiento y autores, estando su origen, probablemente, en la época de desarrollo del pensamiento escolástico. En este artículo pretendemos, en primer lugar, realizar un recorrido cronológico e histórico sobre el tratamiento científico económico del dinero, para, en segundo lugar, poner sobre la mesa la macroeconomía ortodoxa a la que han dado lugar las interpretaciones al respecto, así como los enfoques alternativos frente a este pensamiento dominante. Finalmente, intentamos poner en valor los desarrollos monetarios post-keynesianos, integrados en lo que denominan “Economía Monetaria de Producción”, confrontándolos con la llamada Nueva Síntesis Neoclásica.

Analysis of testosterone pulsatility in women with ovulatory menstrual cycles

Objetivo: Avaliar o padrão pulsátil da secreção da testosterona em mulheres normais. Métodos: Oito mulheres saudáveis com ciclos ovulatórios foram selecionadas. Amostras sanguíneas foram coletadas a cada dez minutos durante seis horas, começando entre 7 e 8 h da manhã, após dez horas de jejum, nas três fases do ciclo menstrual: folicular média (Dia 7), folicular tardia (Dia 12) e lútea (Dia 21). Foram mensurados: testosterona, LH e, no basal, também SHBG. Resultados: A frequência dos pulsos de testosterona, média da amplitude do pulso, porcentagem do incremento da amplitude, duração e intervalos dos pulsos foram similares nas três fases (p > 0,05). A pulsatilidade do LH foi estatisticamente diferente entre as três fases (p < 0,001), caracterizando padrão característico do ciclo ovulatório normal. Conclusões: Esses dados aumentam o conhecimento sobre o padrão de secreção da testosterona no ciclo menstrual humano e representam uma contribuição para a investigação clínica, tanto no hiperandrogenismo como na síndrome de insuficiência androgênica __________________________________________________ ABSTRACT Objective: To evaluate the pattern of the pulsatile secretion of testosterone in normal menstrual cycle. Methods: Eight healthy women with ovulatory menstrual cycles were enrolled. Blood samples were collected at ten-minute intervals for six hours, starting between 7 and 8 am, after a ten-hour fasting, in three phases: mid-follicular (Day 7), late follicular (Day 12) and mid-luteal phase (Day 21). Samples were assayed for testosterone, LH and the baseline also for SHBG. Results: Testosterone pulse frequency, mean amplitude pulse, percentage of increment in pulse amplitude, mean duration of pulses and pulse interval were similar in the three phases. LH pulsatility was statistically different among the three phases (p < 0.001) representing normal ovulatory cycles. Conclusions: These data increase the knowledge about the testosterone secretion profile in the human menstrual cycle and can be used as a contribution to clinical investigation in both hyperandrogenism and androgen insufficiency syndrome
