Anatomy of the floral scape of Bromeliaceae

This paper describes the anatomy of the floral scape for 12 species of Bromeliaceae, belonging to the subfamilies Bromelioideae, Tillandsioideae and Pitcairnioideae. Although all the scapes have a similar organization, there are variations in the structure of the epidermis, cortex and vascular cylinder. Such variations are described for the studied scapes and, when considered together they can help to identify the species. These aspects are described for each scape and discussed under a taxonomic point of view.

[E]scape : anonymat et politique à l'ère de la mobilisation globale: passages chinois pour la communauté qui vient

Le thème de la mobilisation totale est au cœur de la réflexion actuelle sur le renouvellement des modes de subjectivation et des manières d’être-ensemble. En arrière-plan, on trouve la question de la compatibilité entre les processus vitaux humains et la modernité, bref, la question de la viabilité du processus de civilisation occidental. Au cœur du diagnostic: l’insuffisance radicale de la fiction de l’homo oeconomicus, modèle de l’individu privé sans liens sociaux et souffrant d’un déficit de sphère. La « communauté qui vient » (Agamben), la « politisation de l’existence » (Lopez Petit) et la création de « sphères régénérées » (Sloterdijk) nomment autant de tentatives pour penser le dépassement de la forme désormais impropre et insensée de l’individualité. Mais comment réaliser ce dépassement? Ou de manière plus précise : quelle traversée pour amener l’individu privé à opérer ce dépassement? Ce doctorat s’organise autour d’une urgence focale : [E]scape. Ce concept suggère un horizon de fuite immanent : il signe une sortie hors de l’individu privé et trace un plan d’idéalité permettant d’effectuer cette sortie. Concrètement, ce concept commande la production d’une série d’analyses théoriques et artistiques portant sur des penseurs contemporains tels que Foucault, Deleuze ou Sloterdijk, l’album Kid A de Radiohead ainsi que sur le cinéma et l’art contemporain chinois (Jia Zhangke, Wong Kar-Wai, Wong Xiaoshuai, Lou Ye, Shu Yong, Huang Rui, Zhang Huan, Zhu Yu, etc.). Ces analyses sont conçues comme autant de passages ou itinéraires de désubjectivation. Elles posent toutes, d’une manière ou d’une autre, le problème du commun et de l’être-ensemble, sur le seuil des non-lieux du capitalisme global. Ces itinéraires se veulent liminaux, c’est-à-dire qu’ils se constituent comme passages sur la ligne d’un dehors et impliquent une mise en jeu éthopoïétique. Sur le plan conceptuel, ils marquent résolument une distance avec le paradigme de la politique identitaire et la critique des représentations interculturelles.

Parcel theory in three dimensions and the calculation of SCAPE

Slantwise convective available potential energy (SCAPE) is a measure of the degree to which the atmosphere is unstable to conditional symmetric instability (CSI). It has, until now, been defined by parcel theory in which the atmosphere is assumed to be nonevolving and balanced, that is, two-dimensional. When applying this two-dimensional theory to three-dimensional evolving flows, these assumptions can be interpreted as an implicit assumption that a timescale separation exists between a relatively rapid timescale for slantwise ascent and a slower timescale for the development of the system. An approximate extension of parcel theory to three dimensions is derived and it is shown that calculations of SCAPE based on the assumption of relatively rapid slantwise ascent can be qualitatively in error. For a case study example of a developing extratropical cyclone, SCAPE calculated along trajectories determined without assuming the existence of the timescale separation show large SCAPE values for parcels ascending from the warm sector and along the warm front. These parcels ascend into the cloud head within which there is some evidence consistent with the release of CSI from observational and model cross sections. This region of high SCAPE was not found for calculations along the relatively rapidly ascending trajectories determined by assuming the existence of the timescale separation.

Just a failed shopping-scape? Urban and public values of Le Mirail’s dalle

The famous plan for Toulouse-Le Mirail, by Candilis/Josic/Woods (1961), proposed a radical and hitherto new public space, the dalle, an elevated linear ?stem? that wove the whole urban intervention and concentrated all the commercial, social and cultural activity of the neighbourhood. However, the project is today stigmatized as a total social failure. The dalle has been demolished and a traditional commercial street has been implemented. Was demolition the sole alternative for Le Mirail?s future? This paper aims at identifying certain themes around the conception of the dalle, capable of informing today?s theory and practice in the design of new shopping/public-scapes. It reflects on both the most positive values of the project and on its naiveties and mistakes, conscious of the social unrest that aggrandized them. Ultimately, it calls for a deeper reflection on the urban proposals of the Modern Movement, beyond demolition as the only possible solution.

Cartografando movimentos curriculares produzidos nas redes de conversações nos encontrosformações do PROEJA/IFES/ES

Problematiza a constituição do currículo (e da “formação docente” no campo curricular), no cotidiano escolar, na dimensão das conversações. Objetiva acompanhar os movimentos curriculares concernentes ao Proeja entre formas e forças complexas no cotidiano do Ifes – campus Venda Nova do Imigrante (VNI). Compõe com as linhas de pensamentos principalmente de Alves (2008, 2010, 2012); Carvalho (2004, 2008a, 2008b, 2009, 2012); Deleuze (1988, 2002, 2010); Deleuze e Guattari (1995); Ferraço (2007, 2008a, 2008b); Garcia (2011); Guattari (1987, 2004, 2012); Kastrup (2009, 2013); Lopes e Macedo (2011); Lopes (2010, 2011); Oliveira (2005, 2009, 2012); Paiva (2004, 2009); Rolnik (1989); e Spinoza (2013), entremeando os conceitos de movimentos e afetos no campo do currículo em redes na relação híbrida com os encontros-formações docente do/no Proeja. Adota a (não) metodologia cartográfica ao acompanhar movimentos curriculares (des)(re)territorializantes nas redes de conversações, especialmente nos encontrosformações: “Rodas de conversas com professores e demais servidores do Proeja”. Utiliza como principais instrumentos metodológicos a observação participante, a gravação das vozes e o registro em diário de campo. Contribui para outros movimentos de pesquisa ao capturar produzir e analisar dados em que se percebe que: ainda que tenha ocorrido um planejamento coletivo, outras temáticas surgiram nos encontros formações (que não se pretendiam engessados e não objetivavam a paralisação dos fluxos que pedem passagem), e tais assuntos puderam ser usados como disparadores para criação de outros movimentos curriculares; as concepções dos professores sobre a “dificuldade/facilidade” em ministrar aulas para o Proeja e os lugares estabelecidos entre estudantes e docentes no processo ensino-aprendizagem não estão relacionados diretamente, em relação de causa e efeito, à disciplina/área de conhecimento específica que ministram, mas aos agenciamentos, aos ligamentos e às rupturas produzidas nas relações com essas redes de saberes fazeres poderes que envolvem múltiplos agentes: docentes, outros servidores, alunos, experiências e encontros múltiplos dentro fora no espaço tempo do Ifes; uma tríade-refrão coopera para a criação de uma fôrma triangular que enfatiza a noção de um padrão em um processo molar enraizado nas árvores do conhecimento: perfil, seleção e nivelamento, contudo, algumas linhas de fuga dissonantes são criadas por entre as fissuras dos pretensos tons harmônicos; as frases “os professores do IF não estão preparados para ministrar aulas para o Proeja” ou “não há formação/qualificação para os docentes se relacionarem com o Proeja” são utilizadas, em alguns discursos, como escudos-argumentos para a opção-política de não oferta de vagas para a modalidade EJA em composição com fios que afirmam tal especificidade da educação básica, dentro da rede federal, como um “favor social”; processos que envolvem a (des)organização da matriz curricular são considerados por alguns participantes como início, “produto” e objetivo das conversas curriculares e provocam tensões que (i)mobilizam, (não) movimentam entre os afetos dos corpos, podendo levar à (não) ação coletiva; a noção de “mercado de trabalho” ainda impera nos discursos, ciclicamente, enquanto início fim das problematizações do currículo do Ensino Médio e da EJA; a expressão “integração curricular” é constantemente usada nos discursos que circulam o campus, no entanto, os sentidos produzidos, as concepções e as teorias curriculares que embasam a noção de “integração” no currículo são bem diversos; não há totalidades nos discursos, não há homogeneização, não foi efetivada nenhuma coesão/única voz representante (e esse também não era o objetivo desta pesquisa); ainda que o tema da roda se propusesse às conversas curriculares do/no Proeja, nesses encontros, os participantes manifestaram a necessidade de intensificar os movimentos produzidos nas rodas visando à discussão dos currículos textos de todos os cursos e modalidades ofertados pelos campus VNI e na intensificação de espaços para trocas de experiências curriculares cotidianas; na potencialização das diferenças como possibilidades de inventividade nos encontros-formações docente e nas danças curriculares que envolvem diversas relações de aprendizagem no Ifes, algumas experimentações foram produzidas, entre afetos, criando composições(des)(re)territorializantes e ressonando com movimentos que não se restringiram às rodas de conversas, contudo, enredaram-se em fios de outros espaços tempos do campus em tentativas de propagações de currículos multidão.

Comportamento dos cromossômios na meiose de Euryophthalmus rufipennis Laporte (Hemiptera Pyrrhocoridae)

In this paper an account is given of the principal facts observer in the meiosis of Euryophthalmus rufipennis Laporte which afford some evidence in favour of the view held by the present writer in earlier publications regarding the existence of two terminal kinetochores in Hem ip ter an chromosomes as well as the transverse division of the chromosomes. Spermatogonial mitosis - From the beginning of prophase until metaphase nothing worthy of special reference was observed. At anaphase, on the contrary, the behavior of the chromosomes deserves our best attention. Indeed, the chromoso- mes, as soon as they begin to move, they show both ends pronouncedly turned toward the poles to which they are connected by chromosomal fibres. So a premature and remarkable bending of the chromosomes not yet found in any other species of Hemiptera and even of Homoptera points strongly to terminally localized kinetochores. The explanation proposed by HUGHES-SCHRADER and RIS for Nautococcus and by RIS for Tamalia, whose chromosomes first become bent late in anaphase do not apply to chromosomes which initiate anaphase movement already turned toward the corresponding pole. In the other hand, the variety of positions assumed by the anaphase chromosomes of Euryophthalmus with regard to one another speaks conclusively against the idea of diffuse spindle attachments. First meiotic division - Corresponding to the beginning of the story of the primary spermatocytes cells are found with the nucleus entirelly filled with leptonema threads. Nuclei with thin and thick threads have been considered as being in the zygotente phase. At the pachytene stage the bivalents are formed by two parallel strands clearly separated by a narrow space. The preceding phases differ in nothing from the corresponding orthodox ones, pairing being undoubtedly of the parasynaptic type. Formation of tetrads - When the nuclei coming from the diffuse stage can be again understood the chromosomes reappear as thick threads formed by two filaments intimately united except for a short median segment. Becoming progressively shorter and thicker the bivalents sometimes unite their extremities forming ring-shaped figures. Generally, however, this does not happen and the bivalents give origin to more or less condensed characteristic Hemipteran tetrads, bent at the weak median region. The lateral duplicity of the tetrads is evident. At metaphase the tetrads are still bent and are connected with both poles by their ends. The ring-shaped diakinesis tetrads open themselves out before metaphase, showing in this way that were not chiasmata that held their ends together. Anaphase proceeds as expected. If we consider the median region of the tetrads as being terminalized chiasmata, then the chromosomes are provided with a single terminal kinetochore. But this it not the case. A critical analysis of the story of the bivalents before and after the diffuse stage points to the conclusion that they are continuous throughout their whole length. Thence the chromosomes are considered as having a kinetochore at each end. Orientation - There are some evidences that Hemipteran chromosomes are connected by chiasmata. If this is true, the orientation of the tetrads may be understood in the following manner: Chiasmata being hindered to scape by the terminal kinetochores accumulate at the ends of the tetrads, where condensation begins. Repulsion at the centric ends being prevented by chiasmata the tetrads orient themselves as if they were provided with a single kinetochore at each extremity, taking a position parallelly to the spindle axis. Anaphase separation - Anaphase separation is consequently due to a transverse division of the chromosomes. Telophase and secund meiotic division - At telophase the kinetochore repeli one another following the moving apart of the centosomes, the chiasmata slip toward the acentric extremities and the chromosomes rotate in order to arrange themselves parallelly to the axis of the new spindle. Separation is therefore throughout the pairing plane. Origin of the dicentricity of the chromosomes - Dicentricity of the chromosomes is ascribed to the division of the kinetochore of the chromosomes reaching the poles followed by separation and distension of the chromatids which remain fused at the acentric ends giving thus origin to terminally dicentric iso-chromosomes. Thence, the transverse division of the chromosomes, that is, a division through a plane perpendicular to the plane of pairing, actually corresponds to a longitudinal division realized in the preceding generation. Inactive and active kinetochores - Chromosomes carrying inactive kinetochore is not capable of orientation and active anaphasic movements. The heterochromosome of Diactor bilineatus in the division of the secondary spermatocytes is justly in this case, standing without fibrilar connection with the poles anywhere in the cell, while the autosomes are moving regularly. The heterochromosome of Euryophthalmus, on the contrary, having its kinetochores perfectly active ,is correctly oriented in the plane of the equator together with the autosomes and shows terminal chromosomal connection with both poles. Being attracted with equal strength by two opposite poles it cannot decide to the one way or the other remaining motionless in the equator until some secondary causes (as for instances a slight functional difference between the kinetochores) intervene to break the state of equilibrium. When Yiothing interferes to aide the heterochromosome in choosing its way it distends itself between the autosomal plates forming a fusiform bridge which sometimes finishes by being broken. Ordinarily, however, the bulky part of the heterochromosome passes to one pole. Spindle fibers and kinetic activity of chromosomal fragments - The kinetochore is considered as the unique part of the chromosome capable of being influenced by other kinetochore or by the poles. Under such influence the kinetochore would be stimulated or activited and would elaborate a sort of impulse which would run toward the ends. In this respect the chromosome may be compared to a neüròn, the cell being represented by the kinetochore and the axon by the body of the chromosome. Due to the action of the kinetochore the entire chromosome becomes also activated for performing its kinetic function. Nothing is known at present about the nature of this activation. We can however assume that some active chemical substance like those produced by the neuron and transferred to the effector passes from the kinetochore to the body of the chromosome runing down to the ends. And, like an axon which continues to transmit an impulse after the stimulating agent has suspended its action, so may the chromosome show some residual kinetic activity even after having lost its kinetochore. This is another explanation for the kinetic behavior of acentric chromosomal fragmehs. In the orthodox monocentric chromosomes the kinetic activity is greater at the kinetochore, that is, at the place of origin of the active substance than at any other place. In chromosomes provided with a kinetochore at each end the entire body may become active enough to produce chromosomal fibers. This is probably due to a more or less uniform distribution and concentration of the active substance coming simultaneously from both extremities of the chromosome.

Comportamento dos cromossômios no gênero Hypselonotus (Hemiptera -Coreidae)

The three species studied have 19 chromosomes, being one heterochromosome, one pair of microchromosomes and 8 pairs of autosomes. The microchromosomes of Hypselonotus fulvus are amongst the largest we know. During the synizesis, in Hypselonotus fulvus, we can see in several strands that scape from the chromatic knot a place in which they are widley open. As, in that phase the chromosomes have both ends converging to the same place, the openings suggest a side-to-side pairing of the chromosomal threads. The tetrads are like that studied by Piza (1945-1946). The bivalents are united side by side at their entire length. The unpaired part at the midle of the bivalents gives origin to the arms of the cross-shapede tetrads. The chromosomes have a kinetochore at each end. The bivalents sometimes unite their extremities to form ring-shaped figures, which open themselves out before metaphase. The tetrads are oriented parallelly to the spindle axis. At telophase the kinetochores repeli one another, the chiasmata, if present, slip toward the acentric extremities and the chromosomes rotate in order to arrange themselves parallelly to the axis of the new spindle. Separation is therefore through the pairing plane. In the spermatogonial anaphase of Hypselonotus subterpunctatus the chromosomes are curved to the poles, like those described by PIZA (1946) and PIZA and ZAMITH (1946). The sex chromosomes in Hypselonotus interruptus and Hypselonotus fulvus appears longitudinally divided. It is oriented with the ends in the plane of the equator and its chomatids separate by the plane of division. In the second division the sex chromosome, provided as it is with an actve klnetochore at each end, orients itself with its length parallelly to the spindle axis and passes undivided to one pole. Sometimes it is distended between the poles. This corresponds to case (a) established by PIZA (1946) for the sex chromosomes of Hemiptera In Hypselonotus subterpunctatus the sex chromosome, in the first division of the spermatocytes, orients like the tetrads and divides transversaly. In the second division, as its kinetochore becomes inactive, it remans monocentric, does not orient in the spindle, and is finally enclosed in the nearer nucleus. In the secondary telophase it recuperates its dicentricity like the autosomal chromatids. This behavior corresponds to case (c) of PIZA (1946).

A new species of Alpaida (Araneae, Araneidae) from Southeastern Brazil

ABSTRACT Alpaida venger sp. nov. is described based on males and females from Pedra Branca State Park, Rio de Janeiro, Brazil. This species seems to be related to Alpaida scriba (Mello-Leitão, 1940) and Alpaida alticeps (Keyserling, 1879) due to similar body shape and color, but is easily distinguished by the very elongated median apophysis, the massive lobe of tegulum and the hooked paracymbium of male palp. Females have elongated epigyne as A. scriba, but can be distinguished by the wider lips and shorter scape.
