Análise econômica da produção do Maracujazeiro amarelo em sistemas orgânico e convencional

This work was carried out in the city of Maringa, located in the Northwest region of Parana, with the aim of analyzing economically the yellow passion fruit crop (Passiflora edulis Sims. f. flavicarpa Deg.), comparing organic and conventional production systems. To estimate technical coefficients, planting and production costs, and profitability indicators of culture, the data were surveyed from technicians of the region and based in experimental work, carried out at the Experimental Farm of lguaterm from the Maringa State University, in the period of june/2002 to july/2004. The total production costs of the culture in two agricultural years reached a value 12.94% higher for the conventional system, and in this same period the medium index of profitability was 21.39% higher for the organic system. The organic production system was economically feasible and provided a larger index of profitability.

Geographic variation in cranial shape in the Pumpkin Toadlet (Brachycephalus ephippium): A geometric analysis

The description of patterns of variation in any character system within well-defined species is fundamental for understanding lineage diversification and the identification of geographic units that represent opportunities for sustained evolutionary divergence. In this paper, we analyze intraspecific variation in cranial shape in the Pumpkin Toadlet, Brachycephalus ephippium-a miniaturized species composed of isolated populations on the slopes of the mountain ranges of southeastern Brazil. Shape variables were derived using geometric-statistical methods that describe shape change as localized deformations in a spatial framework defined by anatomical landmarks in the cranium of B. ephippium. By statistically weighting differences between landmarks that are not close together (changes at larger geometric scale), cranial variation among geographic samples of B. ephippium appears continuous with no obvious gaps. This pattern of variation is caused by a confounding effect between within-sample allometry and among-sample shape differences. In contrast, by statistically weighting differences between landmarks that are at close spacing (changes at smaller geometric scale), differences in shape within- and among-sample variation are not confounded, and a marked geographic differentiation among population samples of B. ephippium emerges. The observed pattern of geographic differentiation in cranial shape apparently cannot be explained as isolation-by-distance. This study provides the first evidence that the detection of morphological variation or lack thereof, that is, morphological conservatism, may be conditional on the scale of measurement of variation in shape within the methodological formalism of geometric morphometrics.

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t.

Gastric cryptosporidiosis as a clue for the diagnosis of the acquired immunodeficiency syndrome

Infecções oportunistas do trato gastrointestinal constituem ameaça à população crescente de portadores de imunossupressão. O comprometimento do estômago por Cryptosporidium é incomum. Quando identificado no exame histopatológico da mucosa gástrica, é mandatória a investigação do estado imunológico do hospedeiro. São apresentados os dados clinicopatológicos e endoscópicos de uma paciente de 64 anos com gastrite erosiva associada à infecção por Cryptosporidium. O encontro deste agente oportunista no exame histopatológico da mucosa gástrica foi fundamental para esclarecer a doença de base da paciente, que era a síndrome da imunodeficiência adquirida.
