RRS Charles Darwin Cruise 167, 23 Nov - 21 Dec 2004. Sub-seafloor physical properties at Saldanha Seamount, Mid-Atlantic Ridge, and controls on the spatial distribution of hydrothermal venting
No full textCharles Darwin 167 (CD167) was a joint research project carried out by UK and Portuguese scientists from the National Oceanography Centre, Southampton, the University of Durham and the University of Lisbon. The task of CD167 was to carry out geophysical and geological studies at the Mid-Atlantic Ridge. The work area was a ridge offset centred on 36º 34’ N, 33º 26’ W - about 200 n.m. south of the island of Flores in the Azores. At this location, the median valley of the ridge is offset by about 20 km right-laterally, forming a non-transform discontinuity. Of particular interest is a site known as the Saldanha Massif, where previous studies have revealed an area of exposed, tectonically-unroofed mantle rocks and unexpectedly significant hydrothermal circulation with venting near the summit of the massif. A three-dimensional controlled source electromagnetic (CSEM) survey of sub-sea-floor electrical resistivity was carried out over a 10 km2 area centred on the Saldanha Massif. Following CSEM data analysis, the resulting images of electrical structure will be translated into constraints on porosity distribution, interconnectedness and pore fluid properties by means of geophysical effective medium modelling methods. This in turn will address the questions of whether the Saldanha vent site owes its existence to the presence of a deep fracture network, whether this network completely penetrates the thin crustal carapace within the ridge offset, and how far it extends downwards into the underlying mantle rocks. A secondary objective was to collect a series of ridge-perpendicular (approximately east-west) profiles of bathymetry and of gravity and magnetic anomalies, to contribute to regional tectonic studies through improving an international European compilation of such data. This was successfully achieved, and the data have been passed on to our international collaborators. A third objective was to collect sea bottom geological samples, by gravity coring and dredging, for analysis at CREMINER in Lisbon. This objective was also achieved
Olhos, mãos e rostos: a produção pictórica de Eduardo Dias na Florianópolis de 1890 a 1940
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências HumanasEste escrito é um estudo pelas evidências deixadas através das imagens em telas pelo pintor Eduardo Dias em uma Florianópolis correspondente ao período entre os anos de 1890 a 1940. Essas pinturas tornaram-se indícios de uma arte permanecida pelos olhos e mãos de um pintor preocupado em registrar a sua cidade e os rostos de seus habitantes. A iniciativa do artista abriu mais uma fresta de observação do passado através da sensibilidade peculiar de seus traços, cores e formas
On D = 6, N = (2,0) and N = (4,0) Theories
No full textUsing a convolutive field-theoretic product, it is shown here that the “square” of an Abelian D = 6, N = (2, 0) theory yields the free D = 6, N = (4, 0) theory constructed by Hull, together with its generalised (super)gauge transformations. This offers a new perspective on the (4, 0) theory and chiral theories of conformal gravity more generally, while at the same time extending the domain of the “gravity = gauge × gauge” paradigm
Leptoceridae Dias, Quinteiro & Calor, 2015, n. sp.
No full textLeptoceridae from Serra Bonita: New records to Bahia State In this work, seven known species and one new species were collected in Serra Bonita. These species are distributed among seven of the nine genera of Leptoceridae recorded in Brazil: Atanatolica, Grumichella, Neoathripsodes, Nectopsyche, Notalina, Oecetis, and Triplectides. Neoathripsodes and Notalina are new generic records for Bahia state. During the first year, 2008, six species were collected in Serra Bonita: Atanatolica bonita, Grumichella rostrata Thienemann 1905, Notalina cipo Holzenthal 1986, Oecetis martinae, Triplectides gracilis, and Neoathripsodes holzenthali n. sp. The next year, 2009, the six previous and two additional species were collected: Nectopsyche fuscomaculata Flint 1983 and Oecetis furcata. In the four subsequent years, no different additional species of Leptoceridae were collected. Thus, Nectopsyche fuscomaculata, Neoathripsodes holzenthali n. sp., Notalina cipo are new records for Bahia State. Material of all new records is listed below except those for Neoathripsodes holzenthali n. sp., which are detailed in the species description section.Published as part of Dias, Everton S., Quinteiro, Fabio B. & Calor, Adolfo R., 2015, A new species of Neoathripsodes Holzenthal, 1989 (Trichoptera: Leptoceridae) with new generic and species records in Bahia State, Brazil, pp. 370-380 in Zootaxa 4032 (4) on pages 375-376, DOI: 10.11646/zootaxa.4032.4.2, http://zenodo.org/record/23732

Sishiniheia n. gen. was compared to Guabamima de Mello, 1992, Mellopsis Mews & Sperber, 2010, and Pizacris Souza-Dias & Desutter-Grandcolas, 2015. All these genera share similar morphological characters, mainly regarding male genitalia, as the great development of the PsP 2, and the elongated rami. In Guabamima and Sishiniheia n. gen. the pseudepiphallic arms are lateral, pointed, not tubular; in Pizacris and Mellopsis, the pseudepiphallic arms are ventrally-oriented. The phylogenetic relationships among these genera, however, are unknown; a cladistic analysis of Neotropical Luzarinae, with the inclusion of Sishiniheia n. gen., are being performed. For more information about the male genitalia of these genera see Souza-Dias et al. (2015).Published as part of Souza Dias, Pedro G.

Counting BPS Operators in the Chiral Ring of N=2 Supersymmetric Gauge Theories or N=2 Braine Surgery
No full textThis note is presenting the generating functions which count the BPS operators in the chiral ring of a N = 2 quiver gauge theory that lives on N D3 branes probing an ALE singularity. The difficulty in this computation arises from the fact that this quiver gauge theory has a moduli space of vacua that splits into many branches – the Higgs, the Coulomb and mixed branches. As a result there can be operators which explore those different branches and the counting gets complicated by having to deal with such operators while avoiding over or under counting. The solution to this problem turns out to be very elegant and is presented in this note. Some surprises with “surgery” of generating functions arises
