Neste trabalho apresenta-se uma listagem das espécies de artrópodes auxiliares encontradas nos pomares de macieiras (Malus sp.) durante o decorrer dos projectos INTERFRUTA e INTERFRUTA II (durante o período de 2003 a 2007), com comentários relativos à biologia e distribuição das espécies mais abundantes

Os artrópodes auxiliares generalistas associados às bananeiras na ilha Terceira (Açores)

"A biodiversidade dos artrópodes associados às fruteiras dos Açores era, até há poucos anos, quase completamente desconhecida, resumindo-se apenas a listagens de pragas e indicação de uma ou outra espécie de auxiliar (e.g., Garcia & Furtado, 1980; Schanderl & Almeida, 1992; Cruz De Boelpaepe & Teixeira, 1990; Soares et al., 1992, 1994, 1996; Costa-Comelles et al., 1994). Com o projecto INTERFRUTA (Lopes et al., 2005) foi possível realizar um inventário mais ou menos exaustivo da diversidade de artrópodes predadores generalistas que podem actuar como auxiliares no combate a muitas pragas. Este projecto teve início em 2003 e resultou já num maior conhecimento dos artrópodes associados a quatro culturas frutícolas (bananeiras, citrinos, macieiras e pessegueiros) da Ilha Terceira (ver Santos et al. 2005a, b, 2009). Em 2006 este projecto foi continuado através do INTERFRUTA II.

SUBJECT-SPECIFIC MUSCULOSKELETAL MODEL TO IDENTIFY MUSCLE CONTRIBUTION TO THE ACCELERATION PHASE IN ELITE SPRINTING

The purpose of this study was to identify which lower limb joint moments of force and lower limb muscles had the highest contribution to the forward and upward acceleration of the Body Centre of Gravity (BCG) in an elite sprinter during the first step after starting from blocks in 100 meters dash. An induced acceleration analysis approach was used to mechanically ascertain this contribution. Two models were used, one based in a simple multilink rigid body’s model and a second using a musculoskeletal model developed using Opensim. Our results showed a possible synergist action between hip and ankle extensors that allow an optimal combination that resulted in a forward propulsion of the BCG, this results seem to be corroborated using an Opensim musculoskeletal model

Antiphospholipid Syndrome Risk Evaluation

The antiphospholipid syndrome is an acquired autoimmune disorder produced by high titers of antiphospholipid antibodies that cause both arterial and veins thrombosis as well as pregnancy-related complications and morbidity, as clinical manifestations. This autoimmune hypercoagulable state, often associated with coronary artery disease and recurrent Acute Myocardium Infraction, has severe consequences for the patients, being one of the main causes of thrombotic disorders and death. Therefore, it is extremely important to be preventive; being aware of how probable is to have that kind of syndrome. Despite the updated of the APS classification published as Sydney criteria, diagnosis of this syndrome remains challenging. Further research on clinically relevant antibodies and standardization of their quantification are required to improve clinical risk assessment in APS. This work will focus on the development of a diagnosis support system to antiphospholipid syndrome, built under a formal framework based on Logic Programming, in terms of its knowledge representation and reasoning procedures, complemented with an approach to computing grounded on Artificial Neural Networks. The proposed model allowed to improve the diagnosis, classifying properly the patients that really presented this pathology (sensitivity about 92%) as well as classifying the absence of APS (specificity ranging from 89% to 94%)

Issues on Generating Primordial Anisotropies at the End of Inflation

We revisit the idea of generating primordial anisotropies at the end of inflation in models of inflation with gauge fields. To be specific we consider the charged hybrid inflation model where the waterfall field is charged under a U(1) gauge field so the surface of end of inflation is controlled both by inflaton and the gauge fields. Using delta N formalism properly we find that the anisotropies generated at the end of inflation from the gauge field fluctuations are exponentially suppressed on cosmological scales. This is because the gauge field evolves exponentially during inflation while in order to generate appreciable anisotropies at the end of inflation the spectator gauge field has to be frozen and scale invariant. We argue that this is a generic feature, that is, one can not generate observable anisotropies at the end of inflation within an FRW background.Comment: V3: new references added, JCAP published versio

Evaporation residues produced in spallation of 208Pb by protons at 500A MeV

The production cross sections of fragmentation-evaporation residues in the reaction Pb+p at 500A MeV have been measured using the inverse-kinematics method and the FRS spectrometer (GSI). Fragments were identified in nuclear charge using ionisation chambers. The mass identification was performed event-by-event using the B-rho - TOF - Delta-E technique. Although partially-unresolved ionic charge states induced an ambiguity on the mass of some heavy fragments, production rates could be obtained with a high accuracy by systematically accounting for the polluting ionic charge states. The contribution of multiple reactions in the target was subtracted using a new, partly self-consistent code. The isobaric distributions are found to have a shape very close to the one observed in experiments at higher energy. Kinematic properties of the fragments were also measured. The total and the isotopic cross sections, including charge-pickup cross sections, are in good agreement with previous measurements. The data are discussed in the light of previous spallation measurements, especially on lead at 1 GeV
