“Creadores de la profundidad”. Orígenes del movimiento obrero en las minas de los Andes peruanos (1928-1930)

La presente tesis estudia los orígenes del movimiento obrero en las minas de la Sierra Central del Perú a inicios del siglo XX. Ello mediante el análisis de una breve coyuntura de movilización sindical ocurrida entre diciembre de 1928 y noviembre de 1930. El eje analítico de la investigación es doble. De un lado, se examina el rol decisivo que en dicha coyuntura de agitación sindical tuvo un grupo de obreros intelectuales, quienes asumieron el liderazgo del naciente movimiento obrero. De otro lado, se estudian los vínculos entre estos trabajadores y el “Grupo de Lima” dirigido por José Carlos Mariátegui. La tesis consta de cuatro capítulos, dedicados a analizar los sucesivos momentos de la coyuntura de movilización sindical. El primer capítulo contextualiza el análisis en el escenario regional de la Sierra Central peruana, así como en los cambios vinculados a la presencia de la empresa monopólica Cerro de Pasco Copper Corporation a partir de 1902. El segundo capítulo reconstruye los inicios de la agitación obrera, así como los vínculos entre los trabajadores y el “Grupo de Lima”, que se hallaba abocado a la formación del Partido Socialista y la CGTP, la primera organización sindical de alcance nacional en Perú. El tercer capítulo aborda la lucha en pos de la sindicalización, tomando en cuenta las dificultades planteadas por la condición obrera prevaleciente en las minas, el estallido de protestas y la influencia de los militantes comunistas. Finalmente, el cuarto capítulo estudia el momento culminante del período: la realización del Congreso Minero del Centro, la creación de la primera Federación de Trabajadores Mineros y la dura represión gubernamental en contra de los trabajadores, cuyo desenlace fue la desarticulación del movimiento obrero en ciernes.

Condições orais em Minas Gerais: estudo da Carga Global de Doença e o papel dos serviços de saúde

Introdução: Os agravos orais são um problema de saúde pública devido à suaprevalência na população e as complicações físicas e psicológicas advindas de suas ocorrências. Objetivou-se estimar a carga de doença para as condições orais em Minas Gerais, no período 2004 - 2006, e identificar fatores contextuais e de serviços de saúdeassociados. Métodos: Estudo da Carga de Doença para cárie, edentulismo e doençaperiodontal, por sexo e faixa etária. O indicador usado foi o DALY, que medesimultaneamente o impacto da mortalidade e dos problemas de saúde que afetam a qualidade de vida. A Carga de Doença para condições orais foi analisada em números absolutos e taxas / 1.000 habitantes. Os procedimentos ambulatoriais odontológicos foram organizados em série histórica e examinados por meio de análise descritiva. A associação de fatores contextuais com agravos orais foi analisada com modelagem hierárquica. Resultados: Estimou-se 45.514 YLD para agravos orais, com taxa de 2,4/1.000 habitantes. Estimou-se 18.142 YLD para homens e 27.372 YLD para mulheres (1,9/1.000 e 2,8/1.000, respectivamente). O número de YLD para cárie foi de 8.332, com taxas de 0,4/1.000 para ambos os sexos. Estimou-se 33.888 YLD para edentulismo, com taxa de 2,2/1.000 nas mulheres. Na doença periodontal estimou-se 3.217 YLD, resultando em uma taxa de 0,2/1.000 para ambos os sexos. Observou-se aumento da oferta de alguns procedimentos odontológicos ambulatoriais nas Macrorregionais de Saúde menos favorecidas economicamente. As característicassocioeconômicas associaram-se à incidência de cárie dentária e à prevalência de edentulismo.

The intracratonic Caraibas-Itacarambi earthquake of December 09, 2007 (4.9 m(b)), Minas Gerais State, Brazil

On December 9, 2007, a 4.9 m(b) earthquake occurred in the middle of the Sao Francisco Craton, in a region with no known previous activity larger than 4 m(b). This event reached intensity VII MM (Modified Mercalli) causing the first fatal victim in Brazil. The activity had started in May 25, 2007 with a 3.5 magnitude event and continued for several months, motivating the deployment of a local 6-station network. A three week seismic quiescence was observed before the mainshock. Initial absolute hypocenters were calculated with best fitting velocity models and then relative locations were determined with hypoDD. The aftershock distribution indicates a 3 km long rupture for the mainshock. The fault plane solution, based on P-wave polarities and hypocentral trend, indicates a reverse faulting mechanism on a N30 degrees E striking plane dipping about 40 degrees to the SE. The rupture depth extends from about 0.3 to 1.2 km only. Despite the shallow depth of the mainshock, no surface feature could be correlated with the fault plane. Aeromagnetic data in the epicentral area show short-wavelength lineaments trending NNE-SSW to NE-SW which we interpret as faults and fractures in the craton basement beneath the surface limestone layer. We propose that the Caraibas-Itacarambi seismicity is probably associated with reactivation of these basement fractures and faults under the present E-W compressional stress field in this region of the South American Plate.

Paepalanthus hirtellus, a new species of Paepalanthus subsection Actinocephaloides (Eriocaulaceae) from Minas Gerais, Brazil

In this article we describe and illustrate the new species Paepalanthus hirtellus (Eriocaulaceae, Paepalanthoideae). The species is, as far as known, restricted to Pico do Itambe State Park, in the state of Minas Gerais, Brazil. Paepalanthus hirtellus occurs on the campos rupestres of the Espinhaco Range. We compare it with P. lombensis and P. chrysophorus, the two morphologically most similar species. We provide additional comments on the morphological variability, habitat, geographic distribution and we provide its conservation status.

Two new species of Actinocephalus (Eriocaulaceae) from Minas Gerais, Brazil

We describe and illustrate two new species, Actinocephalus delicatus and A. giuliettiae (Eriocaulaceae, Paepalanthoideae), from the Espinhaco Range in Minas Gerais, Brazil, and compare them with the morphologically most similar species. Diagnostic characters, morphological variation, geographic distribution, habitat and conservation status, as well as line drawings, photos and a distribution map are provided for both species.

Minasia ramosa (Asteraceae: Vernonieae), a new species from the Serra do Cabral, Minas Gerais, Brazil

Minasia ramosa, a new species from Brazil, is here described and illustrated. The species is endemic to the campos rupestres of the Serra do Cabral, a western extension of the Espinhaco Range in Minas Gerais. Minasia ramosa is characterized by its narrow ensiform leaves, paniculate inflorescence and totally setuliferous cypselae. The affinities of this species are discussed.

A new species of Vriesea Lindl. (Bromeliaceae, Tillandsioideae) from Serra da Canastra, Minas Gerais State, Brazil

A new species of Vriesea Lindl. belonging to section Xiphion (E. Morren) E. Morren ex Mez. - V. sanfranciscana Versieux & Wand.- is described and illustrated. The species is only known to occur in the Serra da Canastra National Park, located in the southwestern Minas Gerais, Brazil, and is morphologically related to V. atropurpurea Silveira from serra do Cipo, Espinhaco range.

An illustrated checklist of Bromeliaceae from Parque Estadual do Rio Preto, Minas Gerais, Brazil, with notes on phytogeography and one new species of Cryptanthus

A checklist of the 14 genera and 34 species of Bromeliaceae from the Parque Estadual do Rio Preto in Sao Goncalo do Rio Preto municipality, Minas Gerais state, southeastern Brazil, is presented. The Tillandsioideae was the most diverse subfamily and was found to be concentrated in rocky field areas. Bromelioideae is also a species rich subfamily, but its taxa have shown a preference to forested areas and savannas at lower altitudes. Pitcairnioideae is highlighted by its level of endemism, but has only four species. Cryptanthus micrus, a new species found in this area is described and illustrated. Our cluster analysis indicated that the Rio Preto State Park has a Bromeliaceae flora more similar to that from Pico do Itambe and Grao Mogol State Parks. Taxa like Dyckia glandulosa, Orthophytum itambense and Vriesea medusa, which were previously considered to be endemic to Pico do Itambe, now have their area of occurrence extended to Rio Preto. These new occurrences highlight the importance to create a corridor joining these neighboring reserves to connect populations of narrowly ranged or rare species. In this work we present pictures of 19 species in their habitats within the park, and we hope that these illustrations will help in the identification and conservation of these taxa.

Rankamaite from the Urubu pegmatite, Itinga, Minas Gerais, Brazil: Crystal chemistry and Rietveld refinement

A new occurrence of rankamaite is here described at the Urubu pegmatite, Itinga municipality, Minas Gerais, Brazil. The mineral forms cream-white botryoidal aggregates of acicular to fibrous crystals, intimately associated with simpsonite, thoreaulite, cassiterite, quartz, elbaite, albite, and muscovite. The average of six chemical analyses obtained by electron microprobe is (range in parentheses, wt%): Na(2)O 2.08 (1.95-2.13), K(2)O 2.61 (2.52-2.74), Al(2)O(3) 1.96 (1.89-2.00), Fe(2)O(3) 0.01 (0.00-0.03), TiO(2) 0.02 (0.00-0.06), Ta(2)O(5) 81.04 (79.12-85.18), Nb(2)O(5) 9.49 (8.58-9.86), total 97.21 (95.95-101.50). The chemical formula derived from this analysis is (Na(1.55)K(1.28))(Sigma 2.83)(Ta(8.45)Nb(1.64)Al(0.89)Fe(0.01)(3+)Ti(0.01))(Sigma 11.00)[O(25.02)(OH)(5.98)](Sigma 31.00). Rankamaite is an orthorhombic ""tungsten bronze"" (OTB), crystallizing in the space group Cmmm. Its unit-cell parameters refined from X-ray diffraction powder data are: a = 17.224(3), b = 17.687(3), c = 3.9361(7) angstrom, V = 1199.1(3) angstrom(3), Z = 2. Rietveld refinement of the powder data was undertaken using the structure of LaTa(5)O(14) as a starting model for the rankamaite structure. The structural formula obtained with the Rietveld analyses is: (Na(2.21)K(1.26))Sigma(3.37)(Ta(9.12)NB(1.30) Al(0.59))(Sigma 11.00)[O(26.29)(OH)(4.71)](Sigma 31.00). The tantalum atoms are coordinated by six and seven oxygen atoms in the form of distorted TaO(6) octahedra and TaO(2) pentagonal bipyramids, respectively. Every pentagonal bipyramid shares edges with four octahedra, thus forming Ta(5)O(14) units. The potassium atom is in an 11-fold coordination, whereas one sodium atom is in a 10-fold and the other is in a 12-fold coordination. Raman and infrared spectroscopy were used to investigate the room-temperature spectra of rankamaite.
