Influência dos fatores abióticos sobre a variação espaço-temporal de paralonchurus brasiliensis (Steindachner, 1875) (pisces, sciaenidae) componente da fauna acompanhante da pesca de camarões no litoral Norte de São Paulo

Knowledge of the environmental factors influence on the spatial-temporal variation of fishes is important to fisheries management and conservation. Thus, the aim of this work was to analyze the influence of the abiotical factors on the spatial-temporal distribution of Paralonchurus brasiliensis (Pisces, Sciaenidae) caught by-catch with the shrimp fishing of Ubatuba and Caraguatatuba regions, north coast of São Paulo State. The fishes were captured every month from January to December 2002. Samples were collected by otter trawl at 5, 10, 15, 20, 25, 30 and 35m depths. The temperatures (surface and bottom), salinities (surface and bottom), sediment features and organic matters were verified for each depth. During all period of the study 12.642 specimens of P. brasiliensis were captured at Ubatuba and 17.166 at Caraguatatuba, which totalized the biomass of 267 for the first and 339kg for the other region. The females outnumbered males in fish population. The greatest values of biomass and number of individuals were registered at the summer and autumn seasons, while the lowest values were observed at the winter and spring seasons. The greatest abundances were found from 15 to 25m depth. In this study, it was verified that P. brasiliensis is a coastal waters associate species. The spatialtemporal distribution of P. brasiliensis is affected by intrusion of SACW and depth for the coastal region and by depth and sediment in sheltered areas such as Caraguatatuba

Não-preferência para oviposição e alimentação de Spodoptera frugiperda (J. E. Smith, 1797) (Lepidoptera: Noctuidae) por cultivares de amendoim.

This study aimed to select peanut cultivars resistant to Spodoptera frugiperda, selecting non-oviposition and non-feeding preference in choice and no-choice tests. Peanut cultivars with upright growth habit (IAC 5, IAC 8112, IAC 22 and IAC Tatu ST) and runner growth habit (IAC 503, IAC 505, IAC 147, IAC 125, IAC Caiapo and IAC Runner 886) were evaluated. Tests of non-oviposition preference were conducted with newly emerged adults. Adults were fed a 10% honey solution, remaining in cages for 4 days until the start of the evaluations. The evaluations consisted of quantifying the number of eggs and egg masses, followed by calculating the number of eggs per egg mass. To perform non-feeding preference tests, leaf discs from different peanut cultivars were placed in disposable Petri dishes followed by releasing of a third-instar caterpillar for each cultivar. The attractiveness at 1, 5; 10, 15, 30, 60, 120, 360, 720 and 1,440 minutes was evaluated by counting the caterpillars that were feeding on cultivars. The leaf area consumed was evaluated at the end of the experiment for each cultivar. In the tests of non-oviposition and non-feeding preference, with choice or no-choice, none of the cultivars of the upright growth and runner growth habit influenced the oviposition or food of S. frugiperda. Thus, the peanut cultivars showed no resistance of the non-feeding and non-oviposition types.

A invenção da Terra da Luz: história, literatura e paisagem (1875-1914)

Ce travail est un étude de cas qui analyse la construction litéraire du paysage du « Sertão» du Ceará entre la fin du siècle XIX et le début du siècle XX. Pour cela, quelques oeuvre simbole de la production litéraire du Ceará ont été sélectionnés, comme les textes qui suivent: O sertanejo (1875), de José Martiniano de Alencar; Os retirantes (1879), de José Carlos do Patrocínio; A fome (1890), de Rodolfo Marcos Teófilo; Luzia-Homem (1903), de Domingos Olímpio Braga Cavalcanti; Terra de sol: natureza e costumes do Norte (1912), de Gustavo Dodt Barroso et finalement, Aves de arribação (1914), de Antônio Sales. Ces oeuvres non seulement prend la nature comme personage, elles représentent aussi trois moments de la production litéraire du Ceará : romantique, réaliste et naturaliste. A invenção da Terra da Luz se rapporte à l idée d une littérature qui fait remarquer le paysage diurne du Sertão du Ceará, élaborée par ces hommes des lettres dans ses discours formidables, beaux et des matériaux qui viennent de ses rapports avec le monde naturel. Pour réaliser une tel entreprise, les idées de Edmund Burke et Gaston Bachelard se sont constitués en référence de cet étude. Et cette réflexion sur la description, la rêverie et l imagination marchent côte-à-côte au discours de ces littéreurs qui ont construits un espace simbolique spécifique : le sertão du Ceará. Comme ça, quelques thèmes deviennent canonique à la forme de penser, représenter et imaginer l espace du sertão du Ceará. De cette manière, le paysage est beaucoup plus que la contemplation, une fois qu elle est liée aussi à la rêverie poétique, à la mémoire et l imagination. C est de là l invention du paysage, car ces littéreurs n ont pas l accès au paysage purement naturel parce que ses perceptions et sensibilitées sur le monde du sertão ont été historiquement, c est-à-dire, dans un certain temps et espace

Pulsed Nd:YAG laser welding of Ni-alloy Hastelloy C-276 foils

In this study a pulsed Nd:YAG laser was used to join Hastelloy C-276 thin foil with 100 microns thickness. Pulse energy was varied from 1.0 to 2.25 J at small increments of 0.25 J with a 4 ms pulse duration. The macro and microstructures of the welds were analyzed by optical and electronic microscopy, tensile shear test and microhardness. Sound laser welds without discontinuities were obtained with 1.5 J pulse energy. Results indicate that using a precise control of the pulse energy, and so a control of the dilution rate, it is possible to weld Hastelloy C-276 thin foil by pulsed Nd: YAG laser.

Whitham method for the Benjamin-Ono-Burgers equation and dispersive shocks

The Whitham modulation equations for the parameters of a periodic solution are derived using the generalized Lagrangian approach for the case of the damped Benjamin-Ono equation. The structure of the dispersive shock is considered in this method.

Short-wave instabilities in the Benjamin-Bona-Mahoney-Peregrine equation: theory and numerics

In this paper we discuss the nonlinear propagation of waves of short wavelength in dispersive systems. We propose a family of equations that is likely to describe the asymptotic behaviour of a large class of systems. We then restrict our attention to the analysis of the simplest nonlinear short-wave dynamics given by U-0 xi tau, = U-0 - 3(U-0)(2). We integrate numerically this equation for periodic and non-periodic boundary conditions, and we find that short waves may exist only if the amplitude of the initial profile is not too large.

Notas sobre Siegfried Kracauer, Walter Benjamin e a Paris do Segundo Império: pontos de contato

Trata-se de mostrar a originalidade crítica de Siegfried Kracauer diante da experiência da modernidade estética e de discutir as afinidades estético-teóricas de Kracauer e Benjamim ao analisar a Paris da segunda metade do século XIX, o Segundo Império, em particular, como fenômeno originário da sociedade de massas, da indústria cultural e do entretenimento e, sobretudo, do nazi-fascismo. Kracauer durante seu exílio parisiense (1933-41) escreveu uma biografia da sociedade: Jacques Offenbach e a Paris de sua época (Jacques Offenbach und das Paris seiner Zeit). Obra inovadora pelo seu enfoque da história do presente e com pontos de contatos com a Obra das Passagens (Passagen-Werk) ou Paris capital do século XIX de Walter Benjamin.

Psicologia social e processo grupal: a coerência entre fazer, pensar sentir em Sívia Lane

O presente artigo trata da concepção histórica e dialética de processo grupal proposta por Sílvia Lane, que utiliza como base para suas reflexões os pressupostos de materialismo dialético quando considera os aspectos pessoais, as características grupais, a vivência subjetiva e a realidade objetiva e o caráter histórico do grupo. O que pretendemos enfatizar neste artigo é a produção sobre grupo presente em sua obra que foi se construindo no decorrer das décadas de 1980 e 1990, sintetizada no texto O processo grupal. Neste sentido, busca-se trazer as contribuições presentes no conjunto de sua obra, sistematizadas em artigos, coletâneas e livros, em que Sílvia Lane discute a articulação de algumas categorias fundamentais para a análise do processo grupal e suas implicações teóricas, metodológicas e prático-políticas.

Espécies do gênero Eimeria Schneider, 1875 (Apicomplexa: Eimeriidae) em caprinos leitros mantidos em sistema intensivo na região de São Jose do Rio Preto, estado de São Paulo, Brasil.

Were examined 58 dairy goats, 41 kids and 17 adults, Saanen and Alpine breeds, males and females, in intensive system, in the São José do Rio Preto region, São Paulo state, for detection and identification of Eimeria spp. oocysts. The 58 feces samples analyzed by the Centrifugal-flotation technique, were positive for, at least, one Eimeria species. The Eimeria species found in this research were: E. ninakohlyakimovae (77,6%), E. jolchijevi (72,4%), E. alijevi (63,8%), E. christenseni (63,8%), E. arloingi (62,1%), E. caprovina (56,9%), E. hirci (50,0%) and E. caprina (48,3%). It follows that the high rate of the positive animals and the high frequency of the Eimeria species among the animals demonstrated that the disease is common in dairy goats, kids and adults, in intensive system.
