Sexualidade das mulheres durante a gestação: uma revisão da literatura
TCC(especialização) - Universidade Federal de Santa Catarina. Centro de Ciências da Saúde. Programa de Pós-graduação em Enfermagem. Linhas de Cuidado em Saúde Materna, Neonatal e do LactanteObjetivo: identificar as evidências disponíveis na literatura científica sobre a sexualidade da mulher durante a gestação. Metodologia: foi realizada uma revisão da literatura mediante os seguintes passos: seleção da questão de pesquisa; amostragem; avaliação dos estudos primários incluídos; interpretação dos resultados; e apresentação da revisão/síntese do conhecimento. Foi explorada a biblioteca electronica da SciELO. Resultados: dos 03 estudos incluídos na revisão todos afirmaram que o tema sexualidade na gestação é um tema tabu durante as consultas, sejam elas de enfermagem ou em consultórios médicos. Ademais, grande parte das gestantes não busca ajuda médica e poucos são os ginecologistas que questionam sobre a sexualidade de suas pacientes. Conclusão: diante das evidências encontradas, torna-se necessária a maior visibilidade do tema pelos profissionais de saúde, pesquisadores e gestores. Esta sensibilização contribuirá para uma melhor qualidade de vida das gestantes durante este momento importante de suas vidas
Late-time interacting cosmologies and the Hubble constant tension
In this manuscript we reassess the potential of interacting dark matter–dark energy models in solving the Hubble constant tension. These models have been proposed but also questioned as possible solutions to the H0 problem. Here we examine several interacting scenarios against cosmological observations, focusing on the important role played by the calibration of supernovae data. In order to reassess the ability of interacting dark matter–dark energy scenarios in easing the Hubble constant tension, we systematically confront their theoretical predictions using a prior on the supernovae Ia absolute magnitude MB, which has been argued to be more robust and certainly less controversial than using a prior on the Hubble constant H0. While some data combinations do not show any preference for interacting dark sectors and in some of these scenarios the clustering σ8 tension worsens, interacting cosmologies with a dark energy equation of state w < −1 are preferred over the canonical ΛCDM picture even with cosmic microwave background data alone and also provide values of σ8 in perfect agreement with those from weak lensing surveys. Future cosmological surveys will test these exotic dark energy cosmologies by accurately measuring the dark energy equation of state and its putative redshift evolution

New tests of dark sector interactions from the full-shape galaxy power spectrum
We explore the role of redshift-space galaxy clustering data in constraining nongravitational interactions between dark energy (DE) and dark matter (DM), for which state-of-the-art limits have so far been obtained from late-time background measurements. We use the joint likelihood for prereconstruction full-shape (FS) galaxy power spectrum and postreconstruction Baryon Acoustic Oscillation (BAO) measurements from the BOSS DR12 sample, alongside Cosmic Microwave Back ground (CMB) data from Planck: from this dataset combination we infer H0 ¼ 68.02þ0.49 −0.60 km=s=Mpc and the 2σ lower limit ξ > −0.12, among the strongest limits ever reported on the DM-DE coupling strength ξ for the particular model considered. Contrary to what has been observed for the ΛCDM model and simple extensions thereof, we find that the CMB þ FS combination returns tighter constraints compared to the CMB þ BAO one, suggesting that there is valuable additional information contained in the broadband of the power spectrum. We test this finding by running additional CMB-free analyses and removing sound horizon information, and discuss the important role of the equality scale in setting constraints on DM-DE interactions. Our results reinforce the critical role played by redshift-space galaxy clustering measurements in the epoch of precision cosmology, particularly in relation to tests of nonminimal dark sector extensions of the ΛCDM model
Complementary Degradation of Fuel Oil in Superficial Waters and in Axenic Cultures of Aerobic Gram-negative Bacteria Isolated from Venice Lagoon
The percentages of bacteria degrading fuel oil (n-paraffins from C*2 to C28) were determined in three stations in the northern part of Venice Lagoon. Concentrations of paraffin-degrading bacteria ranged from 8 to 70 bacteria per 100 mL in the least polluted station close to the sea, and from 33 to 345 bacteria per 100 mL in the most polluted station near Porto Marghera. Biological oxygen demand with fuel oil additions was higher in this station, where oxygen was totally depleted in 7 and 5 days in November and June respectively. Twenty-five bacterial strains were isolated from agar plates amended with fuel oil as the sole carbon and energy source; only two were Acinetobacter spp. strains. Strain VE-C3 grew in the presence of n-paraffins. Growth was inducible with a generation time of 2.77 h and an oxygen consumption rate of 53 pL h-1 mg-1 of cells (d.w.).
Five other strains thrived on intermediate oxidation products of n-paraffin
Arquitetura e banda desenhada: utopias do habitat ao habitante
Dissertação de mestrado integrado em Arquitetura (área de especialização em Cultura Arquitectónica)Esta prova compromete-se a fazer uma demonstração do potencial, talvez ainda pouco explorado, da banda desenhada como meio para explorar o futuro, da perspectiva da arquitectura. As propostas utópicas ganham um lugar de destaque, sendo experimentações que desafiam os limites, que fazem propostas críticas para novos conceitos do habitar, alcançando novos interesses, sobretudo pelo uso da imagem e do seu impacto. Numa associação plausível, a banda desenhada surge como um exemplo útil do uso da imagem, e na construção de espaços habitados, e é entre teoria da arquitectura e o alcance imagético da banda desenhada que este ensaio se organiza em três volumes. Concentrando-se numa tríade de referências no campo da arquitectura (Le Corbusier, Movimento Metabolista Japonês e o colectivo Archigram) e numa outra no campo da banda desenhada (Moebius, Katsuhiro Otomo e Warren Ellis), os estudos útopicos tornam evidentes as similaridades e linhas que se vão tocando nos dois planos, criando uma comparação paralela na leitura do relatório entre o estrato do real e o estrato da ficção, percebendo a ideia “limpa e funcional” da utopia arquitectónia, e a vivência “suja, desregrada e mais humana” da distopia da banda desenhada. Este trabalho propõe-se a desafiar, não só o arquitecto mas também o cidadão não arquitecto, a tentar perceber um espaço no futuro a partir das suas formas e do modo como este será habitado e, como através da narrativa visual e de diálogo, a ficção pode detalhar de forma interessante espaços que se encontram entre a realidade e a fantasia.This work is committed to demonstrate the potential, perhaps still little explored, of comics as a way to explore the future from the perspective of architecture. The utopian proposals gain a prominent place, being experiments that challenge the limits that make critical proposals for new concepts of inhabiting, reaching new interests, mainly by the use of the image and its impact. In a plausible association, comics appear as useful example of the use of the image, and in the construction of inhabited spaces, and it is between the theory of architecture and the imaginary reach of the comics that this essay is organized in three volumes. Focusing on a triad of references in the field of architecture (Le Corbusier, Japanese Metabolist Movement and the Archigram collective) and another in the field of comics (Moebius, Katsuhiro Otomo and Warren Ellis), utopian studies make clear the similarities and lines that are touching both planes, creating a parallel comparison in the reading of the report between the stratum of the real and the stratum of fiction, perceiving the "clean and functional" idea of the architectural utopia, and the experience "dirty, unruly and more human" of dystopia of the comic strip. This work aims to challenge not only the architect but also the non-architect citizen, to try to perceive a future space from its forms, but also the way it will be inhabited and, as through visual narrative and dialogue, fiction can detail in an interesting way spaces that lie between reality and fantasy
The effects of lichen sclerosus and its treatments on sexuality : case report
Lichen sclerosus is a chronic and autoimmune dermatitis that develops in the anogenital region. It is related to genital alterations with repercussions in sexuality. We present a case of a 60-year-old woman who had several chronic diseases and had been diagnosed with vulvar lichen sclerosusfor 20 years, with no response to multiple treatments (topical corticosteroids, immuno-modulators). She was submitted to vulvectomy; however, it leads to worsen-ing of her condition, presenting obliterated and fibrosed clitoris, atrophic va-ginal lips, and anal and vulvar fissures. She remained with dyspareunia, de-creased sexual desire and difficulty in orgasm. She underwent sexual therapy, adjustment of antidepressant medication and made intercalated use of topical corticosteroids, topical testosterone andvaginal moisturizers, with partial improvement. From this case we can conclude that, although vulvectomy can be related to some degree of improvement in patients with lichen sclerosus, serious complications can occur
Physical properties and evolution of (Sub-)millimeter selected galaxies in the galaxy formation simulation Shark
We thoroughly explore the properties of (sub)-millimeter (mm) selected
galaxies (SMGs) in the Shark semi-analytic model of galaxy formation. Compared
to observations, the predicted number counts at wavelengths (lambda) 0.6-2mm
and redshift distributions at 0.1-2mm, agree well. At the bright end (>1mJy),
Shark galaxies are a mix of mergers and disk instabilities. These galaxies
display a stacked FUV-to-FIR spectrum that agrees well with observations. We
predict that current optical/NIR surveys are deep enough to detect bright
(>1mJy) lambda=0.85-2mm-selected galaxies at z<5, but too shallow to detect
counterparts at higher redshift. A James Webb Space Telescope 10,000s survey
should detect all counterparts for galaxies with mJy. We
predict SMG's disks contribute significantly (negligibly) to the rest-frame UV
(IR). We investigate the 01mJy
lambda=0.85-2mm-selected galaxies finding their: (i) stellar masses are
, with the 2mm ones tracing the most massive galaxies
(); (ii) specific star formation rates (SFR) are mildly
(~3-10x) above the main sequence (MS); (iii) host halo masses are , with 2mm galaxies tracing the most massive halos
(proto-clusters); (iv) SMGs have lower dust masses (),
higher dust temperatures (K) and higher rest-frame V-band
attenuation (>1.5) than MS galaxies; (v) sizes decrease with redshift, from
4kpc at z=1 to <1kpc at z=4; (vi) the Carbon Monoxide line spectra of mJy sources peak at 4->3. Finally, we study the contribution of SMGs
to the molecular gas and cosmic SFR density at 01mJy
sources make a negligible contribution at z>3 and z>5, respectively, suggesting
current observations have unveiled the majority of the star formation at
0<z<10.Comment: Accepted for publication in MNRAS. 28 pages, 22 of main text and
