Ten virtues of structured graphs
No full textThis paper extends the invited talk by the first author about the virtues
of structured graphs. The motivation behind the talk and this paper relies on our
experience on the development of ADR, a formal approach for the design of styleconformant,
reconfigurable software systems. ADR is based on hierarchical graphs
with interfaces and it has been conceived in the attempt of reconciling software architectures
and process calculi by means of graphical methods. We have tried to
write an ADR agnostic paper where we raise some drawbacks of flat, unstructured
graphs for the design and analysis of software systems and we argue that hierarchical,
structured graphs can alleviate such drawbacks

No full textThe Fano variety of lines of a cuspidal cyclic cubic fourfold
No full textWe prove that the Fano variety of lines of a cuspidal cyclic cubic fourfold
is a symplectic variety with transversal A2-singularities and we study the
properties of the nonsymplectic order three automorphism induced by the
covering automorphism on the irreducible holomorphic symplectic manifold
obtained by blowing up the singular locus.Comment: Tobias Heckel added as an author: the results of the paper are

Volatile oil and antioxidants from michelii heckel (myristicaceae) ferrule leaves
No full textThis work describes the phytochemical study of Virola michelii Heckel that occur in the Amazon Region popularly known as ucuúba-preta and its leaves are used in the popular medicine as hot poultice on the skin, to treat infections caused by fungus. The fresh smashed leaves of Virola michelii submitted to the hydrodistilation afforded a volatile oil, which analyzed through coupled system gas chromatograph to mass spectrometer evidenced the occurrence of one monoterpene and of seventeen sesquiterpenes. The ethyl alcohol extract of V. michelii leaves was fractionated by ethyl acetate and aqueous methanol partition, followed by solvent evaporation of the fractions, yielded the respective residues. The ethyl acetate residue submitted to chromatographic techniques, allowed the isolation of three compounds, two furofuran lignan, “eudesmin” (rel- (1S,2R,5R,6S)-2,6-di-(3,4-dimethoxyphenyl]-3,7-dioxabicyclo[3.3.0]octane) and “phillygenol” rel-(1S,2S,5R,6R)-6-(4-hydroxy-3-methoxyphenyl)-2-(3,4-dimethoxyphenyl)-3,7- dioxabicyclo[3.3.0]octane and one phytosterol, the β-sitosterol. The structural determination was based on the interpretation of the 1 H and 13C nuclear magnetic resonance spectra and mass spectra. The isolated furofuran lignans were submitted to test for antioxidant activity with DPPH radical followed by photometric detection. It was observed that the phillygenol was more active than eudesmin, in the assay which quercetin was used as standard.O presente trabalho descreve o estudo fitoquímico de Virola michelii Heckel conhecida como ucuúba-preta, que ocorre na Amazônia, cujas folhas têm sido usadas na medicina popular como emplastos à quente sobre a pele, para reduzir infecções causadas por fungos. As folhas frescas fragmentadas de Virola michelii, submetidas a uma hidrodestilação, forneceram um óleo volátil, que analisado pelo sistema cromatógrafo gasoso acoplado ao espectrômetro de massas permitiu a identificação de um monoterpeno e dezessete sesquiterpenos. O extrato etanólico das folhas de V. michelii submetido ao fracionamento por partição de solventes em acetato de etila e metanol/água rendeu frações, que por evaporação do solvente, deram origem aos respectivos resíduos. Estes, submetidos a técnicas cromatográficas, permitiram o isolamento de três substâncias, sendo duas lignanas furofurânicas, “eudesmina” {rel-(1S,2R,5R,6S)-2,6-di-(3,4–dimetoxifenil)-3,7- dioxabiciclo[3.3.0]octano} e “filigenol” {rel-(1S,2S,5R,6R)-6-(4-hidróxi-3-metoxifenil)-2-(3,4- dimetoxifenil)-3,7-dioxabiciclo[3.3.0]octano} e um fitosterol, o β-sitosterol. A elucidação estrutural foi baseada na interpretação dos espectros de ressonância magnética nuclear de 1 H e de 13C e espectro de massas. As lignanas furofurânicas isoladas foram submetidas a testes para atividades antioxidantes com o radical DPPH em ensaio fotométrico. A substância filigenol se mostrou mais ativa que a substância eudesmina, em ensaio que empregou como padrão a quercetina

The timing of pupping and molting of the Pacific harbor seal, Phoca vitulina richardii, at Punta Banda Estuary, Baja California, Mexico
No full text"Los nacimientos y la muda de Phoca vitulina son procesos anuales que se repiten con alta precisión en el tiempo, aunque éste varía dependiendo del lugar. El conocimiento de la temporalidad de estos eventos permite determinar en qué momento se encuentra el mayor número de individuos en tierra, lo cual es importante para obtener una estimación más precisa de la abundancia de esta especie. En este trabajo se determinó la temporalidad de los nacimientos y la muda de P. v. richardii en el estero de Punta Banda, Baja California, que se desconocía hasta ahora, ahí y en toda su distribución en México. Se realizaron observaciones durante la temporada de cría de 2011 y 2012, y durante la temporada de muda de 2012. Se determinó que la temporada de cría comenzó a mediados de febrero y finalizó a mediados de abril, y que el máximo número de crías ocurrió a mediados de marzo. La etapa tardía de premuda se presentó desde finales de marzo hasta principios de julio, y la máxima proporción de individuos en esta etapa se observó a principios de mayo. El periodo de muda ocurrió desde finales de abril hasta mediados de julio, y la máxima proporción de individuos en muda se observó a principios de junio. El patrón de muda inverso (empieza por el tronco y termina en la cabeza y las aletas) fue el más común. El mayor número de individuos adultos e inmaduros en tierra se encontró durante la temporada de muda, de manera que el periodo más recomendable para realizar conteos, con el fin de estimar la abundancia de focas en la zona, es de principios de mayo a principios de junio.""Pupping and molting of Phoca vitulina are processes that occur each year with high precision, although their timing varies according to location. Knowledge about the timing of these events allows us to determine when the highest numbers of individuals are hauled out, which is important to achieve a good abundance estimation. In this study we determined the timing of pupping and molting of P. v. richardii at Punta Banda Estuary, Baja California (Mexico), previously unknown at this site or along its entire distribution in Mexico. Observations were carried out during the 2011 and 2012 pupping seasons, as well as the 2012 molting season. We determined that the pupping season starts in mid- February and ends in mid-April, and that the maximum number of pups occurs in mid-March. The late premolt stage was observed from the end of March to the beginning of July, with the peak proportion of individuals in this stage at the beginning of May. The molting period extends from the end of April to mid-July, with the peak proportion of individuals molting at the beginning of June. The reverse molt pattern (starting on the torso and ending on the head and flippers) was the most common. The highest number of adult and subadult individuals on land was observed during the molting season; therefore, the best time to carry out counts to estimate seal abundance in this area is from the beginning of May to the beginning of June.
