Abstract: The late antique destruction of two bronze statues of Pausanias - the Spartan general responsible for the Greek victory at the Battle of Plataea (479 BC) - housed in the temple of Athena Chalkioikos in Sparta (Lib. Ep. 1518), has been interpreted as one of the few cases of a violent conflict between pagan and Christian population in Greece. Nevertheless the sources suggest that late antique Sparta was a bastion of Hellenic paganism and give a picture of a small and quiet town ruled by a pagan educated élite, where pagans like Libanius wanted to live. Since there is no evidence of a violent conflict between pagans and Christians in Sparta, and Libanius confirms that in 365 AD all the temples and cult statues were still in place, this paper addresses the issue from a different point of view and offers a new contribution to the history of Sparta in Late Antiquity. By using literary, archaeological and epigraphic evidence the paper explores: 1) the relationship between Roman administration and Spartan élite in the IVth century AD; 2) the historical memory of Pausanias in Late Antiquity. It will be emphasized that the obscure burning of the two statues helped to remove from Sparta the memory of Pausanias - a controversial figure, misrepresented in Late Antiquity and connected to the ancient staseis in Laconia - in order to promote a positive image of Sparta as a city without conflicts and ruled by the political system of Lycurgus (eunomia). As documented by local inscriptions in praise of late Roman governors, the mythical lawgiver Lycurgus was the paradigm of the imperial governors who rebuilded the town in the IVth cent. AD. It can be assumed that while Rome, Constantinople, Antioch and Athens were troubled by political and religious violence or by seditions between different factions, Sparta aimed to revive its traditional model of civic order in the new historical context of Late Antiquity.

Resumen: En muchos países del mundo se suceden actualmente reclamos de reconocimiento público de las uniones homosexuales. Diversos países europeos han introducido normas tendientes a reconocer nuevas modalidades de ser pareja y familia sobre la base de una nueva concepción “de género” de la sexualidad humana. Pero la impresión que surge es que tales reconocimientos no son siempre precedidos de una profundización propiamente jurídica. En tal sentido, a la luz de las recientes solicitaciones político-sociales en materia de sexualidad y de familia, la presente contribución pretende proponer, en una perspectiva filosófico-jurídica, una reflexión sobre la función y el sentido del derecho frente a los cambios sociales.

¿Es viable la coexistencia de acciones de participación y deliberación con el ejercicio de la representación parlamentaria? ¿De qué manera la tecnologia de la información y comunicación ha auxiliado el proceso de interacción entre la sociedad y el parlamento en el cotidiano dei legislativo? ¿Estamos cercanos a un sistema híbrido de democracia representativa y participativa con la incorporación en la agenda legislativa de maneras efectivas de coproducción de leyes? Esta obra intenta responder a estas preguntas, además de evaluar otras experiencias intemacionales con este mismo objetivo. El libro tiene como base el estudio de dos casos en especial de prácticas participativas digitales desarrolladas por parlamentos: el programa e-Democracia de la Cámara de Diputados brasileños y el proyecto Senador Virtual dei Senado chileno. El texto se desarrolla mediante el análisis sistemático de los aspectos institucionales que abarcan elementos organizacionales y políticos, así como de los aspectos sociales comprometidos en la aplicación de la democracia digital en parlamentos. La investigación indica que estos proyectos, en el punto en que se encontraban en el año 2010 presentaron resultados aunque incipientes en lo que concieme a la mejoría de la representatividad en la toma de decisiones, de agregación de inteligencia colectiva, en el proceso legislativo y de la transparencia por parte de la actuación parlamentaria, elementos apreciados por la democracia participativa y deliberativa. No obstante, dichas experiencias poseen el mérito de contribuir con la construcción gradual de mecanismos participativos más efectivos y complementarios ai sistema político.

The microstructures and the characteristics of water-atomized, nitrogen gas-atomized Al powders and ultrasonic argon gas-atomized Al-Li alloy powder were investigated by means of metallography, SEM, Auger electron spectroscopy and X-ray diffraction techniques. Rapidly solidified powders were explosively consolidated into different sized cylinders under various explosive parameters. The explosively consolidated compacts have been tested and analysed for density microhardness, retention of rapidly solidified microstructures, interparticle bonding, fractography and lattice distortion. It is shown that the explosive consolidation technique is an effective method for compacting rapidly solidified powders. The characteristics of surface layers play a very important role in determining the effectiveness of the joints sintered, and the Al-Li alloy explosive compacts present an abnormal softening appearance compared to the original powder.

Species selectivity of the aquatic herbicide dipotassium salt of endothall (Aquathol® K) was evaluated on plant species typically found in northern latitude aquatic plant communities. Submersed species included Eurasian watermilfoil (Myriophyllum spicatum L.), curlyleaf pondweed (Potamogeton crispus L.), Illinois pondweed (Potamogeton illinoensis Morong.), sago pondweed (Potamogeton pectinatus L.), coontail (Ceratophyllum demersum L.), elodea (Elodea canadensis Michx.) and wildcelery (Vallisneria americana L.). Emergent and floating-leaf plant species evaluated were cattail (Typha latifolia L.), smartweed (Polygonum hydropiperoides Michx.), pickerelweed (Pontederia cordata L.) and spatterdock (Nuphar advena Aiton). The submersed species evaluations were conducted in 7000 L mesocosm tanks, and treatment rates included 0, 0.5 1.0, 2.0, and 4.0 mg/L active ingredient (ai) endothall (dipotassium salt of endothall). The exposure period consisted of a 24-h flow through half-life for 7 d. The cattail and smartweed evaluation was conducted in 860 L mesocosm tanks, and the spatterdock and pickerelweed evaluations were conducted in 1600 L mesocosm tanks. Treatment rates for the emergent and floating-leafed plant evaluations included 0, 0.5, 2.0 and 4.0 mg/L ai endothall, and the exposure period consisted of removing and replacing half the water from each tank, after each 24 h period for a duration of 120 h. Biomass samples were collected at 3 and 8 weeks after treatment (WAT). Endothall effectively controlled Eurasian watermilfoil and curlyleaf pondweed at all of the application rates, and no significant regrowth was observed at 8 WAT. Sago pondweed, wildcelery, and Illinois pondweed biomass were also significantly reduced following the endothall application, but regrowth was observed at 8 WAT. Coontail and elodea showed no effects from endothall application at the 0.5, 1.0, and 2.0 mg/L application rates, but coontail was controlled at 4.0 mg/L rate. Spatterdock, pickerelweed, cattail, and smartweed were not injured at any of the endothall application rates.

In clear water, diquat [6,7-dihydrodipyrido (1,2-1a:2',1'-c) pyrazinediium dibromide] provides excellent submersed Plant control at low concentrations, such as <0.5 mg active ingredient (ai) L-1: however. turbid water conditions can interfere with the activity and effectiveness of this herbicide. Little work has been done to examine what ranges of turbidity caused by different Suspended sediment types affect diquat efficacy against a target species. A growth chamber study was conducted rising diquat against the submersed macrophyte -egeria (Egeria densa Planch.) under a range Of turbid conditions. Two materials were used to create turbid beater conditions: 100% bentonite clay for a "worst-case" scenario and a natural partial-clav (20% clay). Results indicated that a high rate of diquat (2 mg ai L-1) controlled egeria under relatively low levels of turbidity (5-10 NTU) using bentonite clay: however. higher levels (25 to 50 NTU) of turbidity essentially blocked effectiveness of diquat when applied at all rates tested (0.5. 1, 2 mg ai L-1). When using a natural partial-clay sediment, rates of 1 to 2 mg ai L-1 diquat provided good control of egeria in moderately turbid water (15 NTU). Additional evaluations rising different clay types would be useful to determine the effect of inorganic turbidity oil diquat efficacy.

The potential of mefluidide (N-(2,4-dimethyl-5[[trifluromethyl) sulfonyl] amino] phenol) acetamide) to act as a submersed aquatic plant growth regulator was evaluated using a laboratory bioassay system. Main stem elongation of hydrilla (Hydrilla verticillata (L.f.) Royle) and Eurasian watermilfoil (Myriophyllum spicatum L.) was effectively reduced by mefluidide at low concentrations. The lowest effective concentration of mefluidide that reduced stem length in Eurasian watermilfoil (100 yg a.i./L) was 5 times lower than that for hydrilla (500 yg a.i./L). Short-term net photosynthetic rates of these plants were not affected by mefluidide at concentrations as high as 1000 yg a.i./L. The minimum exposure time required to maintain an inhibitory effect for at least 28 days at a concentration of 500 yg ai.i./L was 3 to 7 days for Eurasian watermilfoil and 7 to 14 days for hydrilla. The results suggest that mefluidide is a more effective growth regulator for Eurasian watermilfoil than hydrilla. Exogenously applied gibberellic acid (GA) did not completely overcome the inhibitory effect of mefluidide even when GA was added at a high concentration (10-5 M). In addition, the internodal lengths of stems treated with mefluidide were not reduced as they were when treated with gibberellin synthesis inhibitors. The reduction of main stem elongation by mefluidide appeared to be due to the inhibition of new cell and tissue development at the stem tip rather than from inhibition of GA biosynthesis.

Two previously reported DNA polymorphisms of sterol regulatory element binding transcription factor 1 (SREBP1) and liver X receptor alpha (LXRα) and two DNA polymorphisms of fatty acid desaturase 1 (FADS1) were evaluated for associations with fatty acids in brisket adipose tissue of Canadian cross-bred beef steers. The polymorphism of 84 bp insert/deletion in intron 5 of SREBP1 was significantly associated with the concentration of 9c C17:1 (P=0.013). The G>A single nucleotide polymorphism (SNP) in the exon 4 of LXRα gene was associated with the concentration of 9c, 11t C18:2 (P=0.04), sum of conjugated linoleic acids (CLA) (P=0.025) and 11c C20:1(P=0.042). Two DNA polymorphisms in the promoter region of FADS1, deletion/insertion of ->GTG in rs133053720 and SNP A>G in rs42187276, were significantly associated with concentrations of C17:0 iso, C17:0 ai, total branched chain fatty acids (BFA), 12t C18:1, 13t/14t C18:1, 15t C18:1, and 13c C18:1 (P<0.05). Further studies are needed to validate the associations and to delineate the roles of the gene polymorphisms in determining the fatty acid composition in beef tissues.

Guillaume Raynal, historiador e filósofo francês, nasceu em Saint-Geniez-en Rouergue em 11 de abril de 1713 e morreu em Choillot, em 6 de março de 1796. Estudou no Colégio dos Jesuítas de Pézenas, distinguindo-se como pregador e professor. Abandonou o hábito jesuita para se dedicar à filosofia e à história, publicando numerosos artigos no Mercure de France. Tendo sido alvo de um mandado de prisão, refugiou-se na Prússia e mais tarde na Rússia; retornou à França em 1787. ‘Histoire philosofique et politique’ foi publicada simultaneamente pelo mesmo editor em duas impressões, contendo cinco volumes a primeira e dez volumes a segunda. Foi uma das obras que mais ínfluenciou o movimento da Revolução Francesa, tendo o autor utilizado opiniões e, eventualmente, a colaboração de Diderot e Holbach, entre outros contemporâneos. Proibido na França e ai queimado em 1781, este importante trabalho de Raynal teve mais de trinta edições num periodo de vinte anos e foi traduzido para quase todos os idiomas europeus. Segundo Borba de Moraes, ‘esta edição de Genebra é a melhor e mais bela’. Na impressão de dez volumes existentes na Biblioteca da Câmara, a seção referente ao Brasil encontra-se no volume 5.

Este é o tomo III da Coleção Voyages, relations et mémoires originaux pour servir a l'histoire de la découverte de l'Amerique, da editora Ternaux-Compans. Embora o prefácio do editor francês afirme ser esta a primeira versão francesa do famoso livro de Staden so o Brasil, J.C. Rodrigues fala de uma edição francesa em Amsterdã, de 1714, se, contudo, fornecer detalhes. Mesmo sendo esta a segunda tradução francesa, é também rara. Narra a odisséia vivida pelo autor durante nove meses como prisioneiro dos Tupinambás, fonte de consulta importante sobre o período inicial de nossa história. Staden descreve, além das experiências de seu cativeiro, suas viagens ao Brasil, desde os portos de origem. Preocupa-se em citar os nomes das pessoas, com quem lidou em diversas circunstâncias. é a primeira publicação sobre os índios brasileiros e, ainda hoje, na opinião de Borba de Moraes "constitui uma das mais valiosas fontes da etnologia em geral e da tupinologia especialmente".
