Production, characterization, and properties of beta-glucosidase and beta-xylosidase from a strain of Aureobasidium sp.

beta-Glucosidase and beta-xylosidase production by a yeastlike Aureobasidium sp. was carried out during solid-state and submerged fermentation using different carbon sources and crude enzymes were characterized. beta-Glucosidase and beta-xylosidase exhibited optimum activities at pH 2.0-2.5 and 3.0, respectively. These enzymes had the maximum activities at 65degreesC and were stable in a wide pH range and at high temperatures.

Artisanal fisheries in urban reservoirs: a case study from Brazil (Billings Reservoir, São Paulo Metropolitan Region)

Billings Reservoir is an urban reservoir located in the São Paulo Metropolitan Region. Tt supports 101 active artisanal fishermen. To describe this fishery, landings were recorded daily between February 1996 and January 1997 at Colonia (23 degrees 50' 57 S; 46 degrees 40' 02 W). In every landing, a data collector recorded catch, effort, fishing gears and fishing grounds. A total of 147 593 kg of fish were recorded in 3515 fishing trips. The exotic Nile tilapia, Oreochromis niloticus (L.), was the main species exploited (81.4% of the annual catches). Five other species were also targeted: the characid Astyanax eigenmaniorum (Cope) (13.0% of the annual catches); the erythrinid Hoplias aff malabaricus (Block) (2.1%); the exotic cyprinid Cyprinus carpio L. (Campos & Fernandez-Yepez) (2.4%); the curimatid Cyphocharax modestus L. (1.1%); and the pimelodid Rhamdia sp. (0.1%). Two main groups of fishermen were discriminated using Principal Components Analysis; these were associated with the type of fishing gear and fishing strategies, i.e. those who exploited Nile tilapia with cast nets and beating gill nets, and those who exploited other species with set gill nets. Management and maintenance of this fishery should consider the positive top-down effects that Nile tilapia could have in controlling eutrophication and also the social benefits.

As parcerias entre prefeituras paulistas e o setor privado na política educacional: expressão de simbiose?

L'article présente les résultats finaux de l'enquête inter-institutionnelle qui a eu pour objet d'analyser la nature et les conséquences de partenariats conclus entre des secteurs privés et des gouvernements municipaux de la métropole de São Paulo pour le service de l'éducation à la maternelle et à l'enseignement élémentaire. La période a correspondu aux années 1996 à 2006, sachant que la perception d'une augmentation des responsabilités des municipalités pour l'offre éducationnelle, suite à la municipalisation de l'enseignement élémentaire, pourrait stimuler la sous-traitance de l'offre et la privatisation de l'éducation municipale. L'étude présente des tendances en relation avec trois modalités de partenariat: subvention publique pour l'offre de places en institutions privées de l'éducation élémentaire; acquisition de systèmes privés de l'enseignement et recours à des cabinets de conseil privés pour la gestion de l'éducation municipale. Les tendances perçues dans l'analyse indiquent que les actuelles relations entre les sphères publiques et privées dans le champ de l'éducation, suite à la décentralisation survenue dans le secteur, représentent un mouvement dans le sens de sa privatisation.

O Grêmio da Paulista e o lazer do ferroviário rio-clarense

This article turns to the memory of a not too distant past, to investigate the cultural leisure evidence and its development in the city of Rio Claro which has been shown by the Recreation Club Employee of the Companhia Paulista de Estradas de Ferro (GRECPEF), identifying the leisure activities and the relation of these railway employee with the club. For the claims of the research an exploratory investigative model had been used focusing the relationship of GRECPEF with the social history of the city of Rio Claro. Data had been collected through literature review and semi-structured interviews with railway retire employee, who are part of the partner board of the Recreation Club. Within this context one can see that this club is a reference to the leisure activities of the railway employee, and has significant importance and influence on the setting up of a leisure culture in the city.

Insights into metal ion binding in phospholipases A(2): ultra high-resolution crystal structures of an acidic phospholipase A(2) in the Ca2+ free and bound states

The electrophile Ca2+ is an essential multifunctional co-factor in the phospholipase A(2) mediated hydrolysis of phospholipids. Crystal structures of an acidic phospholipase A(2) from the venom of Bothrops jararacussu have been determined both in the Ca2+ free and bound states at 0.97 and 1.60 angstrom resolutions, respectively. In the Ca2+ bound state, the Ca2+ ion is penta-coordinated by a distorted pyramidal cage of oxygen and nitrogen atoms that is significantly different to that observed in structures of other Group I/II phospholipases A(2). In the absence of Ca2+, a water molecule occupies the position of the Ca2+ ion and the side chain of Asp49 and the calcium-binding loop adopts a different conformation. (c) 2005 Elsevier SAS.

Caracterização da região 3'-terminal do genoma de um isolado brasileiro do Southern bean mosaic virus

O presente trabalho caracteriza a região 3'-terminal do genoma de um isolado do Southern bean mosaic virus encontrado no Estado de São Paulo (SBMV-SP). O RNA foi extraído de partículas virais purificadas e submetido a RT-PCR usando oligonucleotídeos desenhados para amplificar 972 nt da região 3'-terminal do RNA viral. Foi obtido fragmento de tamanho esperado que inclui o gene da proteína capsidial e a região 3'-terminal não codificadora. O gene da proteína capsidial (ORF4) contém 801 nucleotídeos, incluindo-se o códon de terminação UGA, com seqüência deduzida de 266 aminoácidos e massa molecular estimada de 28.800 Da. Sessenta e um aminoácidos terminais da ORF2 estão sobrepostos na ORF4. O sinal de localização nuclear, encontrado dentro do Domínio R na região 5'-terminal da ORF4 de alguns sobemovírus, não foi identificado no SBMV-SP. Esse dado pode explicar a ausência de partículas virais do SBMV-SP no núcleo celular. A seqüência do SBMV-SP apresentou identidade de nucleotídeos e aminoácidos de, respectivamente, 91% e 93% com o isolado Arkansas (SBMV-ARK) descrito nos EUA. Os resultados obtidos indicam que o SBMV-SP e o SBMV-ARK são isolados muito proximamente relacionados.

Triple photon production at the Tevatron in technicolor models

We study the process p (p) over bar --> gammagammagamma as a signal for associated photon-technipion production at the Tevatron. This is a clean signature with relatively low background. Resonant and non-resonant contributions are included and we show that technicolor models can be effectively probed in this mode. (C) 2002 Elsevier B.V. B.V. All rights reserved.

Nonlinear Gravitational Waves: Their Form and Effects

High-order upwinding and the hydraulic jump

This work is concerned with the computation of incompressible axisymmetric and fall three-dimensional free-surface flows. In particular, the circular-hydraulic jump is simulated and compared with approximate analytic solutions. However, the principal thrust of this paper is to provide a real problem as a test bed for comparing the many existing convective approximations. Their performance is compared; SMART, HLPA and VONOS emerge as acceptable upwinding methods for this problem. Copyright (C) 2002 John Wiley Sons, Ltd.
