First record of epicadus trituberculatus (Taczanowski, 1872) (araneae, thomisidae, stephanopinae) in the Brazilian Northeast

We present the first record of Epicadus trituberculatus (Taczanowski, 1872) from the Northeast Region of Brazil. The new record is based on six specimens observed in two areas of montane semi-deciduous tropical forest located in two municipalities: Guaramiranga and Pacatuba, Ceará state, Brazil. Of the six specimens observed we collected manually only three to preserve as voucher material. In Brazil, E. trituberculatus has a wide distribution range, which extends from the Atlantic Forest, Amazon, and Cerrado biomes and the Pampa ecoregion. With the new record there are currently six known species of Epicadus in northeastern Brazil155937940CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPnão temnão temnão temThis study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brasil(CAPES), Finance Code 001 (G.A.

Number of repetition after different rest intervals between static stretching and resistance training

AbstractObjectiveThe purpose of this study was to investigate the effects of different intervals between static stretching for hip adductor, quadriceps and hamstring muscles and resistance training in repetition performance.MethodTwenty-two trained men were submitted to the 10 repetition maximum test and retest for leg extension, leg curl and hip adduction exercises. Three protocols were conducted in a randomized design – PWI: resistance training immediately after static stretching; P15: fifteen-minute rest interval between static stretching and resistance training; P30: thirty-minute rest interval between static stretching and resistance training.ResultsThe total number of repetition [(sets*repetitions)+exercises] performed under P30 (84.55±1.68) was significantly higher than P15 (79.73±1.89) and PWI (68.09±2.03), respectively. Significant differences were also found between P15 and P30.ConclusionsTherefore, 30-minute interval between static stretching and resistance exercises was needed to achieve greater repetition performance. Thus, static stretching for lower limbs may be avoided before a resistance training session

Autonomous multi-dimensional slicing for large-scale distributed systems

Slicing is a distributed systems primitive that allows to autonomously partition a large set of nodes based on node-local attributes. Slicing is decisive for automatically provisioning system resources for different services, based on their requirements or importance. One of the main limitations of existing slicing protocols is that only single dimension attributes are considered for partitioning. In practical settings, it is often necessary to consider best compromises for an ensemble of metrics. In this paper we propose an extension of the slicing primitive that allows multi-attribute distributed systems slicing. Our protocol employs a gossip-based approach that does not require centralized knowledge and allows self-organization. It leverages the notion of domination between nodes, forming a partial order between multi-dimensional points, in a similar way to SkyLine queries for databases. We evaluate and demonstrate the interest of our approach using large-scale simulations.This work received support from the Portuguese Foundation for Science and Technology under grant SFRH/BD/71476/2010

Radio Observations of the January 20, 2005 X-Class Event

We present a multi-frequency and multi-instrument study of the 20 January 2005 event. We focus mainly on the complex radio signatures and their association with the active phenomena taking place: flares, CMEs, particle acceleration and magnetic restructuring. As a variety of energetic particle accelerators and sources of radio bursts are present, in the flare-ejecta combination, we investigate their relative importance in the progress of this event. The dynamic spectra of {Artemis-IV-Wind/Waves-Hiras with 2000 MHz-20 kHz frequency coverage, were used to track the evolution of the event from the low corona to the interplanetary space; these were supplemented with SXR, HXR and gamma-ray recordings. The observations were compared with the expected radio signatures and energetic-particle populations envisaged by the {Standard Flare--CME model and the reconnection outflow termination shock model. A proper combination of these mechanisms seems to provide an adequate model for the interpretation of the observational data.Comment: Accepted for publication in Solar Physic
