Cladomorphus trimariensis sp. nov. é descrita de Três Marias, Minas Gerais. A nova espécie difere de C. phyllinus Gray, 1835 principalmente pelo opérculo e placa micropilar do ovo, ausência de espinhos nas pernas médias e posteriores e pelas projeções distais nos tergos IV e V, que são menos desenvolvidas.

A espécie Heilipus odoratus Vanin & Gaiger, 2005 (Coleoptera, Curculionidae, Molytinae) é considerada o principal inseto-praga de frutos de Pau-rosa (Aniba rosaeodora, Ducke, Lauraceae). Recentemente descrita, pouco se conhece sobre seus aspectos biológicos, tendo este trabalho como objetivo contribuir para o estudo comportamental da espécie, como também fornecer técnicas de sexagem de indivíduos adultos, a partir da estridulação. Para tanto, dividiu-se os indivíduos em dois grupos, os que estridulavam e os que não estridulavam, e estes foram dissecados e a ocorrência de estridulação associada ao sexo de cada indivíduo. Do total de indivíduos observados, a maioria dos machos (92,2%, N = 115) emitiu som por estridulação, sendo dotados de órgãos estridulatórios na face interna posterior de seus élitros e no penúltimo tergito, enquanto que a totalidade das fêmeas (N = 92) não expressou tal comportamento e são desprovidas de tais aparatos. Este resultado é o primeiro registro da ocorrência de atividade estridulatória em H. odoratus.

In this chapter we portray the effects of female education and professional achievementon fertility decline in Spain over the period 1920-1980 (birth cohorts of 1900-1950).A longitudinal econometric approach is used to test the hypothesis that the effectsof women s education in the revaluing of their time had a very significant influence onfertility decline. Although in the historical context presented here improvements inschooling were on a modest scale, they were continuous (with the interruption of theCivil War) and had a significant impact in shaping a model of low fertility in Spain. Wealso stress the relevance of this result in a context such as the Spanish for which liberalvalues were absent, fertility control practices were forbidden, and labour forceparticipation of women was politically and socially constrained.

Treball de recerca realitzat per alumnes d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2010. Els objectius estudiats han estat diversos. D’una banda, analitzar de la presa de decisions des d'una perspectiva ètica. D’altra banda, obtenir informació sobre uns processos i una realitat del món productiu que afecta la manera com s'acaba plantejant la lluita contra la malaltia i la promoció de la salut en els àmbits públic i privat. I finalment, esbrinar quin és el paper de l'ànim de lucre en la presa de decisions de la indústria farmacèutica.

The Guilleries are a small and mountainous area located in the north-westem part of the Catalonian Coastal Ranges where metamorphic and igneous Paleozoic rocks are exposed. After the main hercynian folding this area was affected by a brittle deformation that is mainly manifested by the intrusion of a very large number of dykes of granodiorite and the development of a complex joint system. Trends of dykes indicate that their intrusion was related to a SE-NW extension, whose estimated value is 40% on an average. This extension seems to stand, although without any associated igneous event, with the development of NE-SW directed joints which make the main set. Five families more were developed later, onegently-dipping and fou upright; the latter trending roughly SE-NW, ENE-WSW, ESE-WNW and N-S. AU the joint sets appear in the metasedimentary Paleozoic rocks and in the hercynian intrusive bodies. Concerning the ages, joints that belong to the NE-SW and SE-NW directed sets and also those slightly dipping have been attributed to the late-hercynian times and all the other are considered to be later

Es descriu un aflorament volcànic inèdit localitzat al massís del Montgrí. Es troba a l'Aixart de la Conca, just al límit meridional de l'antigabase Loran de l'Estartit, dins el terme municipal de Torroella de Montgrí. Es tracta d'una xemeneia volcànica enclavada en les calcàries del cretaci inferior. Les bretxes i basalts que la constitueixen tenen un grau d'alteració molt elevat. Aquests materials han estat fortament erosionats i han donat lloc a una depressió tancada, d'aspecte semblant a una dolina, que fa uns 220 m de diàmetre màxim i té una profunditat d'uns 7 m
