Sacode a poeira e dá a volta por cima: resiliência em mulheres que vivenciaram violência sexual

O objeto deste estudo foi o processo de construção da resiliência em mulheres que vivenciaram violência sexual. A violência sexual contra a mulher é um problema antigo no mundo, onde o Brasil dispõe de elevadas estatísticas. As justificativas para a violência contra a mulher constroem-se sob normas e preceitos sociais de gênero, os quais definem as diferenças nos papéis e responsabilidades dos homens e das mulheres na sociedade e na família. As consequências físicas e psicológicas para a mulher em situação de violência sexual são alarmantes, podendo ocasionar traumas por longo prazo ou até mesmo para a vida inteira, impedindo-a de retomar seus direitos humanos e de se reinserirem em suas famílias e na sociedade. Entretanto, após a vivência de uma violência algumas mulheres têm seus comportamentos transformados a fim de retomarem o curso de suas vidas. Tais comportamentos dizem respeito à postura resiliente diante à violência sexual vivida e à sua superação. Reconhecendo este comportamento como uma nova possibilidade de promoção da saúde dessas mulheres, traçou-se como objetivo geral do estudo compreender o processo de construção da resiliência em mulheres que vivenciaram violência sexual. Desenvolveu-se uma pesquisa exploratória com abordagem qualitativa, realizada através da coleta da história de vida com seis mulheres que vivenciaram violência sexual atendidas em um hospital municipal do Rio de Janeiro (Brasil), referência no atendimento dessas mulheres. Os dados produzidos foram interpretados à luz da modalidade temática da análise de conteúdo de Bardin. Deste processo emergiram duas categorias: A violência sexual vivida expressa nas atitudes do cotidiano: sentimentos e emoções e A resiliência de mulheres em situação de violência sexual. Na primeira categoria identificaram-se as atitudes, sentimentos e emoções decorrentes da adversidade. Destacaram-se os sentimentos de medo, tristeza, culpa e perda como sendo as principais mudanças ocorridas com a violência. Na segunda categoria emergiram elementos existentes na vida das mulheres que vivenciaram violência sexual e que favoreceram no processo de construção da resiliência, sendo os aspectos individuais, familiares e sociais. A pesquisa considerou que a resiliência é elemento fundamental na promoção da saúde das mulheres que vivenciaram violência sexual assim como uma oportunidade de melhoria de sua qualidade de vida, uma vez que reduz os agravos decorrentes dessa violência e incorpora sentido de vida, serenidade, autoconfiança, autossuficiência e perseverança na vida da mulher. Contudo, a resiliência para ser desenvolvida precisa além dos aspectos individuais da mulher, uma rede de apoio familiar e social significativa e eficaz. A consulta de Enfermagem estabelecida nos princípios da humanização, integralidade e dialogicidade entre profissional e a mulher, seja nas Estratégias de Saúde da Família ou nos ambientes ambulatoriais e hospitalares, caracteriza-se como campo fértil na promoção e apoio a essa rede familiar e social. A enfermeira torna-se facilitadora na construção da resiliência em mulheres em situação de violência sexual, onde é preciso oferecer escuta sensível e sem preconceitos, incentivar a construção de sentido de vida, a recuperação da autoestima e autoconfiança e de sua reinserção social.

Neutron-neutron scattering parameters from the ^3He(d,t)2p and ^3H(d,^3He)2n reactions

The energy spectra of tritons and Helium-3 nuclei from the reactions ³He(d,t)2p, ³H(d,³He)2n, ³He(d,³He)pn, and ³H(d,t)pn were measured between 6° and 20° at a bombarding energy of 10.9 MeV. An upper limit of 5 μb/sr. was obtained for producing a bound di-neutron at 6° and 7.5°. The ³He(d,t)2p and ³H(d,³He)2n data, together with previous measurements at higher energies, have been used to investigate whether one can unambiguously extract information on the two-nucleon system from these three-body final state reactions. As an aid to these theoretical investigations, Born approximation calculations were made employing realistic nucleon-nucleon potentials and an antisymmetrized final state wave function for the five-particle system. These calculations reproduce many of the features observed in the experimental data and indicate that the role of exchange processes cannot be ignored. The results show that previous attempts to obtain information on the neutron-neutron scattering length from the ³H(d,³He)2n reaction may have seriously overestimated the precision that could be attained.

Ratio of natural isotopes of nitrogen. I. Primary results: soils of Dombes [Translation from: Revue d'Ecologie et de Biologie du Sol 14, 279-287, 1977]

Utilization of the heavy isotope of nitrogen as a tracer has found numerous applications in soil biology. It allows better definition of different stages of the nitrogen cycle, in particular the immobilization-mineralization cycle. In this work, the authors report the results of calculations of natural isotope ratios of nitrogen in samples of water, soil and vegetation prevailing in Dombes and discuss the possibilities of errors and coefficients of fractionation.

Modulation of the effectiveness of 17-alpha-hydroxy-20-beta-dihydroprogesterone or of a gonadotrophic extract on the in vitro intrafollicular maturation of oocytes of the rainbow trout Salmo gairdnerii by various non-maturing steroids [Translation from: Compte Rendu Hebdomadaire des Seances de l'Academie des Sciences, Paris, Series D 281, 811-814, 1975]

The effectiveness of 17 α-hydroxy-20 β-dihydroprogesterone (17 α-20 β Pg) or of a trout hypophyseal gonadotrophic extract on the in vitro intrafollicular maturation of trout oocytes can be modulated by steroids which do not have a direct maturing effect; the effectiveness of the gonadotrophic extract is lowered by oestradiol and oestrone and increased by testosterone. As these steroids have no significant effect on maturation induced by 17 α-20 β Pg, the site of their activity is probably in the follicular envelopes. Corticosteroids, and Cortisol and cortisone in particular increase the effectiveness of the gonadotrophic extract, but increase the effectiveness of 17 α-20 β Pg even more strongly, suggesting that this 'progestagen' has a direct effect on oocyte sensitivity.

I. Electronic processes in α-sulfur. II. Polaron motion in a D.C. electric field

Part I: The mobilities of photo-generated electrons and holes in orthorhombic sulfur are determined by drift mobility techniques. At room temperature electron mobilities between 0.4 cm²/V-sec and 4.8 cm²/V-sec and hole mobilities of about 5.0 cm²/V-sec are reported. The temperature dependence of the electron mobility is attributed to a level of traps whose effective depth is about 0.12 eV. This value is further supported by both the voltage dependence of the space-charge-limited, D.C. photocurrents and the photocurrent versus photon energy measurements.

As the field is increased from 10 kV/cm to 30 kV/cm a second mechanism for electron transport becomes appreciable and eventually dominates. Evidence that this is due to impurity band conduction at an appreciably lower mobility (4.10^-4 cm²/V-sec) is presented. No low mobility hole current could be detected. When fields exceeding 30 kV/cm for electron transport and 35 kV/cm for hole transport are applied, avalanche phenomena are observed. The results obtained are consistent with recent energy gap studies in sulfur.

The theory of the transport of photo-generated carriers is modified to include the case of appreciable thermos-regeneration from the traps in one transit time.

Part II: An explicit formula for the electric field E necessary to accelerate an electron to a steady-state velocity v in a polarizable crystal at arbitrary temperature is determined via two methods utilizing Feynman Path Integrals. No approximation is made regarding the magnitude of the velocity or the strength of the field. However, the actual electron-lattice Coulombic interaction is approximated by a distribution of harmonic oscillator potentials. One may be able to find the “best possible” distribution of oscillators using a variational principle, but we have not been able to find the expected criterion. However, our result is relatively insensitive to the actual distribution of oscillators used, and our E-v relationship exhibits the physical behavior expected for the polaron. Threshold fields for ejecting the electron for the polaron state are calculated for several substances using numerical results for a simple oscillator distribution.

O divisor de águas da política imperial: D. Pedro II, a conciliação e o Marquês de Paraná (1853-1856)

A Conciliação política foi um tema muito altercado no meado do Oitocentos no Segundo Reinado brasileiro. Este debate fora intensamente travado entre os principais partidos imperiais, Liberal e Conservador, que se alternavam no poder ao longo de quase 50 anos de comando do imperador D. Pedro II. Sobre seu governo, considerado por Joaquim Nabuco como a Grande Era Brasileira, é que este autor legou à historiografia posterior a sua obra máxima: Um Estadista do Império. Nossa dissertação parte da seguinte premissa: D. Pedro II no desejo de reinar, governar e administrar, acima dos partidos, encetou o seu Pensamento Augusto, isto é, a Conciliação. Os liberais acusavam a Conciliação de esvaziar suas propostas ao serem implementadas pelos conservadores. Estes que se encontravam no poder desde 1848, liderados pelos saquaremas, rechaçaram completamente tal ideia, pois entendiam que esta política patrocinada pela Coroa poderia enfraquecer seu partido. O Receio virou realidade, mediante algumas das medidas tomadas pelo Gabinete, pois para tal empreendimento, de compor um ministério com políticos liberais e conservadores, a Coroa contou com Honório Hermeto Carneiro Leão, Marquês de Paraná, para chefiar o primeiro gabinete conciliatório da história do Segundo Reinado enfrentando várias resistências, principalmente entre os referidos saquaremas. O sucesso do gabinete creditou-se à força, tato e prudência do Marquês e, principalmente, ao pensamento do Imperador. A partir daí a história política do Segundo Reinado tomou novas feições.

Multi-channel 2-D pattern transfer model based on imaging optics for submarine laser uplink communication

An optical communication scheme of 2-D pattern transfer based on imaging optics for submarine laser uplink communication (SLUC) is suggested. Unlike the methods aiming at avoiding neighboring crosstalk used in traditional multi-channel optical beam transferring, we make full use of the overlapping of each spreading beam other than controlling divergence effect of each beam to avoid interference noise. The apparent parameters have been introduced to simplify theoretical analysis of optical pattern transfer problem involving underwater condition, with the help of which the complex beam propagation inside two kinds of mediums can be easily reduced to brief beam transfer only inside air medium. In this paper, optical transmission path and receiver terminal optics geometry have been described in detail. The link range equation and system uplink performance analysis have also been given. At last, results of a proof-of-concept experiment indicate good feasibility of the proposed SLUC model. © 2007 Elsevier GmbH. All rights reserved.

Production of positive controls for calcivirus-specific PCR using recombinant baculiovirus technology

Recent advances in our knowledge of the genetic structure of human caliciviruses (HuCVs) and small round-structured viruses (SRSVs) have led to the development of polymerase chain reaction (PCR)-based molecular tests specific for these viruses. These methods have been developed to detect a number of human pathogenic viruses in environmental samples including water, sewage and shellfish. HuCVs and SRSVs are not culturable, and no animal model is currently available. Therefore there is no convenient method of preparing viruses for study or for reagent production. One problem facing those attempting to use PCR-based methods for the detection of HuCVs and SRSVs is the lack of a suitable positive control substrate. This is particularly important when screening complex samples in which the levels of inhibitors present may significantly interfere with amplificiation. Regions within the RNA polymerase regions of two genetically distinct human caliciviruses have been amplified and used to produce recombinant baculoviruses which express RNA corresponding to the calicivirus polymerase. This RNA is being investigated as a positive control substrate for PCR testing, using current diagnostic primer sets. Recombinant baculovirus technology will enable efficient and cost-effective production of large quantities of positive control RNA with a specific known genotype. We consider the development of these systems as essential for successful screening and monitoring applications.

TRANSFER OF ANALYTICAL METHODS FOR THE CHARACTERISATION OF NATURAL PRODUCTS TO R&D PROCESSES OF IDOKI

IDOKI SCF Technologies S.L. is a technology-based company, set up on September 2006 in Derio (Biscay) with the main scope of developing extraction and purification processes based on the use of supercritical fluid extraction technology (SFE) in food processing, extraction of natural products and the production of personal care products. IDOKI¿s researchers have been working on many different R&D projects so far, most of them using this technology. However, the optimization of a SFE method for the different matrices cannot be performed unless we have an analytical method for the characterisation of the extracts obtained in each experiment. The analytical methods are also essential for the quality control of the raw materials that are going to be used and also for the final product. This PhD thesis was born to tackle this problem and therefore, it is based on the development of different analytical methods for the characterisation of the extracts and products. The projects that we could include in this thesis were the following: the extraction propolis, the recovery of agroindustrial residues (soy and wine) and the dealcoholisation of wine.On the one hand, for the extraction of propolis, several UV-Vis spectroscopic methods were used in order to measure the antioxidant capacity and the total polyphenol and flavonoid content of the extracts. A SFC method was also developed in order to measure more specific phenolic compounds. On the other hand, for the recovery of agroindustrial residues UV-Vis spectroscopy was used to determine the total polyphenol content and two SFC methods were developed to analyse different phenolic compounds. Extraction methods such as MAE, FUSE and rotary agitation were also evaluated for the characterisation of the raw materials.Finally, for the dealcoholisation of wine, the development of a SBSE-TD-GC-MS and DHS-TD-GC-MS methods for the analysis of aromas and a NIR spectroscopic method for the determination of ethanol content with the help of chemometrics was necessary. Most of these methods are typically used in IDOKI¿s lab as routine analyses apart from others not included in this PhD thesis.
