Dos atos confessos aos afetos não-ditos: Um olhar sob as múltiplas experiências femininas a partir da análise dos discursos jurídicos, jornalísticos e orais

Women, subjectiveness, experimentations. This paper walks through gender, sexuality, body and subjectivity, bounding as the focus denaturalize the representations of womanlinessstaff and manliness and the modeled subjectivity by normative discusses that shows the transcendency based on multiplicities of experiences, wishes and life way wattled by men and women from the Caicó City s society in the decades from 1900 to 1945. For this, it was adopted a dialogic methodology inlcluding bibliographic and theorist references as well as sources like articles from Jornal das Moças (Lady s Journal); defloration s crime processes, abortion, infanticide and body lesions; iconographic sources and Caicó citizen memories in the period commented. Based on that sources, this work analyze the discursive construction of feminine through Justice and Jornal das Moças that paved by sanitarian, normalizing and moralizing discourses has spread clichés and stereotypes of womanlinessstaff and manliness, which has resulted by to universalize the experiences feminines in polarities and binary oppositions regarding to manliness, it has delineated them as asexual, irrational, anesthesiaed for pleasure and biologically meant to home activities modeling subjectivities that did not create ways for the singularization processes. This polarities, effects of sexual regulatory practices and gender legitimate the representations of courtship, maternity and honor, that although it has been incorporated not passivant on the building of the poor men and women subjectivity, it did not support itself in view of socio-cultural and economic reality of the poorest society side. Therefore, on this work emerge a plurality of women who has transited past the public sphere, who interlaced amorous informal relationships, who has kept relationships before the marriage, who hás established multiples familiar arrangements and helpful networks, who was single mothers without being considered dishonored women by social groups, who made matrimonial agreements without the rules of a formal civil marriage, who made use of beverageey to provoke the menstruation constituting multiples ways to experiment the life. This subjective feminine experimentations turned it possible to notice that representations concerning about the body, sexuality, date, maternity and honor of this women has constituted itself while molecularies and particulares . It was the affection not commented of the feminine sexuality that turned it possible to analyze the construction of singular subjectivities as a opened process, continuous, active, begetting new lands, life ways and wishes cartographies

Sociedade, mulher e educação nos romances de Graciliano Ramos

This paper, Society, woman and education in Graciliano Ramos' novels, is a study object from the history of woman's education in the 1930 s, it is shown as a reading of woman's representation and the configuration of the Brazilian society in that period. São Bernardo, Angustia and Vidas Secas written by Graciliano Ramos (1892-1953) from Alagoas, are used here as sources associated with the reading of the Constitutions, of the Civil Code and of some presidential messages of that decade, also with the texts produced by other scholars that present some relationship within the thematic of this approach. The representation concepts and the configuration are essential for the production of this text. I run over to the configuration concept given by Chartier (1988, p.21) a definition to representation that can be understood as a relationship between a present image and an absent object that having the value of this because it is hamonized with it. I fall back upon the configuration concept given by Elias (1969) that understands it as been a social group performed by an interdependent network that occurs within individuals as a whole joined by any reason. The totality of each individual actions with each other, permeated by tension points and balance, is what characterizes each configuration; it can be a teachers and students meeting in a classroom or a friends' encounter in the bar table, for instance. The attempt of understanding woman's representation, being educated or not, the hole attributed to her in society according to her instruction degree and the way that same society saw this woman guided me through categories that were defined throughout the successive readings: gender, civil status, education, language domain, sexuality, marriage, family, ideal woman. I accomplish this reading that was possible to do - with the pretension of not having lost the relationship between history and literature nor forgotten each one peculiarities

A educação da mulher em Lima Barreto

Lima Barreto has built an educational conception of women in his fictional productions despite nuances inciting scholars to debate his writings and label him as misogynist and philogynist. Thus, the objective of this study is to comprehend, through signs present in his literary works, how women used to be educated in early twentieth century to accomplish the historical differences in gender relations. The main reason for this extract is the periodicity of his publications that started in 1900 by means of chronicles in newspapers and ended in 1922 after his death. For this, we identified codes and rules forged in the social processes to be assimilated by children through diverse institutions, aiming to incite the production of behaviors and social practices represented by the existence men and women in an ever changing society. Gender relations are analyzed within a society for their configuration concept by Nobert Elias (1970) as interdependence bonds among individuals. An investigative method proposed by Ginzburg (1989) was the most adequate to conduct the research on the work of Lima Barreto because it enables us to reconstruct the education concept for women. The dramas and novels analyzed point out the construction of categories such as women education, family, love and seduction revealing the engagement of Lima Barreto with the social problems of the period investigated. It was concluded that gender differentiation has come from family education which kept men and women in opposing sides giving them a marriage perspective that, after consummated, would bring frustration to women causing them to adopt confronting practices against domination strategies through celibacy or adultery. This research constitutes a reflection based on determined representations like justice, respect and duties that were the ideas defended by Lima Barreto in his writings, concerning both broader situations in social life and particular gender relations

História das mulheres idosas do Grupo Aurora da Vida Campina Grande-PB (1940-1950)

La recherche intitulée l Histoire des femmes agées du group Aurore de La Vie: Campina Grande-PB (1940-1950) a surgit comme consequence de mon observation sur les interêts de femmes en retrouner à l école aprés qu elles étaient arrivées aux soixante ans, um moment de la vie que malgré son importance est encore considerée par trop de gens comme des moments d être seul jusqu à la fin de la vie. Alors, nous avons formulé la question la plus importante de ce travail: Quel est l histoire de l éducation des femmes agées du group Aurore de La Vie, dans le période de son education d enfant? Un group de 25 femmes qui ont étudié le projet Digna, on a fait une seletion de treize agées, entre 65 et 80 ans, qui s appellent: Perpétua, Florinda, Benta, Ambrósia, Celestine, Cordélia, Circe, Filomena, Desdêmona, Dorotéia, Ofelia, Martítius e Nausica. Beaucoup d intelectuels nous ont aidé avec la base theórico-methodologique et nous ont presenté l histoire des excludées comment une histoire en construction. Parmis ces intelectuelles on rencontre Chartier, Halbwachs, Elias, Perrot, Bosi, Bezerra, Morais et Machado. Pendant notre recherche nous avons employés des narrations, des entrevues, des questions ouvertes ou les femmes puissent parler sur l histoire de leur vie. Nous avons regardé aussi le fiche des agées, le arquive de La Secretarie Municipale de Assistence Social (SEMAS) du Hôtel de Ville de Campina Grande-PB. Nous avons aussi étudié sur la legislation relié à la tematique de la Constituition Brésilienne dans l estatute et dans la Politique Nacional de l age. Notre étude nous a donné des analises sur les themas: pauvresse, travail, sourvenirs, jeux e aussi punitions scolaires. Nous sommes arrivés à la conclusion qu à l époque de son enfance, l éducation formale était déjá determinée pour le mariage, la pró-création la famille. Enfim toujours dédans de la maison excludées du reste du monde. Nous avons compris que pesquiser cet object d étude est un contribut avec l histoire des excludées en cassant le silence des femmes lesqueles on été ignorées par presque toute la prodution historiographique

Caracterização de estruturas planares com substratos Iso/Anisotrópicos truncados através da técnica da ressonância transversa modificada

This work presents a theoretical and numerical analysis using the transverse resonance technique (TRT) and a proposed MTRT applied in the analysis of the dispersive characteristics of microstrip lines built on truncated isotropic and anisotropic dielectric substrates. The TRT uses the transmission lines model in the transversal section of the structure, allowing to analyze its dispersive behavior. The difference between TRT and MTRT consists basically of the resonance direction. While in the TRT the resonance is calculated in the same direction of the metallic strip normal axis, the MTRT considers the resonance in the metallic strip parallel plane. Although the application of the MTRT results in a more complex equivalent circuit, its use allows some added characterization, like longitudinal section electric mode (LSE) and longitudinal section magnetic mode (LSM), microstrips with truncated substrate, or structures with different dielectric regions. A computer program using TRT and MTRT proposed in this work is implemented for the characterization of microstrips on truncated isotropic and anisotropic substrates. In this analysis, propagating and evanescent modes are considered. Thus, it is possible to characterize both the dominant and higher order modes of the structure. Numerical results are presented for the effective permittivity, characteristic impedance and relative phase velocity for microstrip lines with different parameters and dimensions of the dielectric substrate. Agreement with the results obtained in the literature are shown, as well as experimental results. In some cases, the convergence analysis is also performed by considering the limiting conditions, like particular cases of isotropic materials or structures with dielectric of infinite size found in the literature. The numerical convergence of the formulation is also analyzed. Finally, conclusions and suggestions for the continuity of this work are presented

Análise de antenas de microfita em rampa com múltiplas camadas dielétricas

The present work deals with the ana1ysis of microstrip patch antennas printed on tapered dielectric substrates. We investigate the influence ofthe substrate height variations on the properties of configurations such as microstrip patch antennas, microstrip patch antennas with overlay and suspendeô microstrip patch antennas. The dielectric substrates can be isotropic or anisotropic ones. This accurate analysis is based on the full-wave formulation. It is carried out initially for the determination of the impedance matrix, through the use of the spectral¬domain immitance approach. We use a model based on a segmentation of the considered line into uniform microstrip line subsections. Normalized phase constants and characteristic impedances are obtained by means of the Galerkin numerical technique. Then, the cascaded combination of the uniform microstrip subsections are analyzed through an interactive procedure. Numerical results are presented for the input reflection coefficient, voltage standing wave ratio, resonant frequency, and radiation pattems ofthe E_plane and H-plane diagrams. It is found that the variations in the substrate height profile produce a great influence on the bandwidth of microstrip antennas. This procedure gives bandwidth improvements without altering considerably the resonant frequency. Furthermore, the tapered microstrip antenna can be used as a lightweight altemative for bandwidth control and to eXtend the use of microstiip antenna technology to a wider variety of applications. Finally, suggestions for the continuity of this work are presented

Aplicações de arranjos de antenas de microfita com patch supercondutor

This work has as main objective the study of arrays of microstrip antennas with superconductor rectangular patch. The phases and the radiation patterns are analyzed. A study of the main theories is presented that explain the microscopic and macroscopic phenomena of superconductivity. The BCS, London equations and the Two Fluid Model, are theories used in the applications of superconductors, at the microstrip antennas and antennas arrays. Phase Arrangements will be analyzed in linear and planar configurations. The arrangement factors of these configurations are obtained, and the phase criteria and the spacing between the elements, are examined in order to minimize losses in the superconductor, compared with normal conductors. The new rectangular patch antenna, consist of a superconducting material, with the critical temperature of 233 K, whose formula is Tl5Ba4Ca2Cu9Oy, is analyzed by the method of the Transverse nTransmission Line (TTL), developed by H. C. C. Fernandes, applied in the Fourier Transform Domain (FTD). The TTL is a full-wave method, which has committed to obtaining the electromagnetic fields in terms of the transverse components of the structure. The inclusion of superconducting patch is made using the complex resistive boundary condition, using the impedance of the superconductor in the Dyadic Green function, in the structure. Results are obtained from the resonance frequency depending on the parameters of the antenna using superconducting material, radiation patterns in E-Plane and H -Plane, the phased antennas array in linear and planar configurations, for different values of phase angles and different spacing between the elements

Localização de faltas em linhas de transmissão de múltiplos terminais a partir de registros oscilográficos sincronizados via transformada wavelet

The electric energy is essential to the development of modern society and its increasing demand in recent years, effect from population and economic growth, becomes the companies more interested in the quality and continuity of supply, factors regulated by ANEEL (Agência Nacional de Energia Elétrica). These factors must be attended when a permanent fault occurs in the system, where the defect location that caused the power interruption should be identified quickly, which is not a simple assignment because the current systems complexity. An example of this occurs in multiple terminals transmission lines, which interconnect existing circuits to feed the demand. These transmission lines have been adopted as a feasible solution to suply loads of magnitudes that do not justify economically the construction of new substations. This paper presents a fault location algorithm for multiple terminals transmission lines - two and three terminals. The location method is based on the use of voltage and current fundamental phasors, as well as the representation of the line through its series impedance. The wavelet transform is an effective mathematical tool in signals analysis with discontinuities and, therefore, is used to synchronize voltage and current data. The Fourier transform is another tool used in this work for extract voltage and current fundamental phasors. Tests to validate the location algorithm applicability used data from faulty signals simulated in ATP (Alternative Transients Program) as well as real data obtained from oscillographic recorders installed on CHESF s lines.

Acoplador e linha de lâmina unilateral e bilateral com substrato fotônico

The aim of this work is to characterize and use the characteristic parameters of the planar structures constructed with fin lines looking for their applications in devices, using PBG Photonic Band Gap photonic materials as substrate, operating in the millimeter and optic wave bands.The PBG theory will be applied for the relative permittivity attainment for the PBG photonic substrate s and p polarizations. The parameters considered in the structures characterization are the complex propagation constant and the characteristic impedance of unilateral and bilateral fin lines that were obtained by the use of the TTL Transverse Transmission Line Method, together with the Method of the Moments. The final part of this work comprises studies related to the behavior of the asymmetric unilateral fin line coupler with photonic substrate. This research opens perspectives for new works in this modern area. Numerical results are shown by means of bi-dimensional and three-dimensional graphics. Conclusions and suggestions for future works are also presented

Efeito da inclinação do plano de terra para antenas de microfita multicamadas com elementos parasitas fractais

This work presents the analysis of an antenna of fractal microstrip of Koch with dielectric multilayers and inclinations in the ground plane, whose values of the angles are zero degree (without inclinations), three, seven and twelve degrees. This antenna consists of three dielectric layers arranged vertically on each other, using feeding microstrip line in patch 1, of the first layer, which will feed the remaining patches of the upper layers by electromagnetic coupling. The objective of this work is to analyze the effects caused by increase of the angle of inclination of the ground plane in some antenna parameters such as return loss, resonant frequency, bandwidth and radiation pattern. The presented results demonstrate that with the increase of the inclination angle it is possible to get antennas with characteristics multiband, with bigger bandwidth, and improving the impedance matching for each case analyzed, especially the larger angle

Análise de onda completa de superfície seletiva em freqüência do tipo anteparo duplo

This work presents a theoretical analysis and numerical and experimental results of the scattering characteristics of frequency selective surfaces, using elements of type patch perfectly conductor. The structures are composed of two frequency selective surfaces on isotropic dielectric substrates cascaded, separated by a layer of air. The analysis is performed using the method of equivalent transmission line in combination with the Galerkin method, to determine the transmission and reflection characteristics of the structures analyzed. Specifically, the analysis uses the impedance method, which models the structure by an equivalent circuit, and applies the theory of transmission lines to determine the dyadic Green's function for the cascade structure. This function relates the incident field and surface current densities. These fields are determined algebraically by means of potential incidents and the imposition of the continuity of the fields in the dielectric interfaces. The Galerkin method is applied to the numerical determination of the unknown weight coefficients and hence the unknown densities of surface currents, which are expanded in terms of known basis functions multiplied by these weight coefficients. From the determination of these functions, it becomes possible to obtain numerical scattered fields at the top and bottom of the structures and characteristics of transmission and reflection of these structures. At work, we present numerical and experimental results for the characteristics of transmission and reflection. Comparisons were made with other results presented in literature, and it was observed a good agreement in the cases presented suggestions continuity of the work are presented

Desenvolvimento de antenas de microfita com aberturas nos patches condutores através do método da segmentação

Microstrip antennas are widely used in modern telecommunication systems. This is particularly due to the great variety of geometries and because they are easily built and integrated to other high frequency devices and circuits. This work presents a study of the properties of the microstrip antenna with an aperture impressed in the conducting patch. Besides, the analysis is performed for isotropic and anisotropic dielectric substrates. The Multiport Network Model MNM is used in combination with the Segmentation Method and the Greens function technique in the analysis of the considered microstrip antenna geometries. The numerical analysis is performed by using the boundary value problem solution, by considering separately the impedance matrix of the structure segments. The analysis for the complete structure is implemented by choosing properly the number and location of the neighboor element ports. The numerial analysis is performed for the following antenna geometries: resonant cavity, microstrip rectangular patch antenna, and microstrip rectangular patch antenna with aperture. The analysis is firstly developed for microstrip antennas on isotropic substrates, and then extended to the case of microstrip antennas on anisotropic substrates by using a Mapping Method. The experimental work is described and related to the development of several prototypes of rectangular microstrip patch antennas wtih and without rectangular apertures. A good agreement was observed between the simulated and measured results. Thereafter, a good agreement was also observed between the results of this work and those shown in literature for microstrip antennas on isotropic substrates. Furthermore, results are proposed for rectangular microstrip patch antennas wtih rectangular apertures in the conducting patch

Sistema radicular e nutrição da soja em função da compactação do solo

A compactação do solo diminui o crescimento radicular, podendo afetar tanto o desenvolvimento quanto a produtividade da soja. No presente trabalho, estudaram-se os efeitos da compactação subsuperficial na morfologia radicular da soja (Glycine max L. Merrill), procurando relacioná-los ao crescimento e à nutrição da planta. O 'Primavera' foi cultivado até os 37 dias da emergência, em vasos onde a camada de 15-18,5 cm de profundidade foi campactada a 1,03, 1,25, 1,48 e 1,72 g/cm³, em um latossolo vermelho-escuro com 80% de areia e 16% de argila e cuja compactação em subsuperfície levou a um acúmulo de raízes na camada superficial do vaso, sem grandes conseqüências na nutrição da planta. Na densidade aparente de 1,72 g/cm3, as raízes não conseguiram penetrar, embora já houvesse alguma restrição ao crescimento na densidade de 1,25 g/cm³. Quando a camada compactada apresentava resistência à penetração de 0,69 MPa, houve uma redução de 50% no crescimento radicular da soja.
