A plateau detected in lead accumulation in subsurface deciduous enamel from individuals exposed to lead may be useful to identify children and regions exposed to higher levels of lead

In a previous study, we showed 4 times more lead in surface deciduous enamel (1.9-5.9 mu m) of a notoriously contaminated area (Bauru, Sao Paulo State, Brazil) in comparison to samples from a region with no lead contamination described (Ribeirao Preto, Sao Paulo State, Brazil). The samples from the more superficial enamel (1.9-3.18 mu m) showed higher amounts of lead and the highest variability, while in the subsurface enamel (3.18-5.9 mu m) a plateau in lead content was detected in children living in the contaminated environment (around 600 mu g/g). Here we expand our previous study, and use only samples obtained from subsurface enamel (Ribeirao Preto, n = 186; Bauru, n = 20). We tried to distinguish regions with more children with lead above the threshold of 600 mu g/g of lead in enamel. We tested whether differences in the percentage of children with ""high"" lead (>= 600 mu g/g) could be observed among the different Kindergartens studied in Ribeirao Preto. We also tested whether these results were different from the ones provided by conventional comparison of the data. Ribeirao Preto showed almost 4 times less lead than Bauru (p < 0.0001), and a statistically significant difference was found only in Ribeirao Preto between Kindergarten 2 and 5 (p<0.01). Twelve percent of the children from Ribeirao Preto had ""high"" lead, while 55% of the children from Bauru did so. However, when we looked at the percentages of children with ""high"" lead in each Kindergarten, and compared them, a whole new picture emerged, in which we could see children with ""high"" lead concentrated mainly in 3 Kindergartens from Ribeirao Preto, with Kindergarten 5 with 33% of the children with ""high"" lead, being statistically different from all Kindergartens, except 4 and 6. The threshold of 600 mu g/g of lead in subsurface enamel was tentatively settled here after the plateau seen in exposed children, and enabled us to identify locations with more children exposed to a higher amount of lead.

Aplicação para intervenção em terapia ocupacional com o Leap Motion

O projeto “À Descoberta das Ilhas” surge das lacunas de atenção e motivação por parte das crianças na realização de exercícios na terapia ocupacional, aliadas a uma subjetividade na análise do seu progresso. Direcionado para crianças com dificuldades de integração bilateral motora, com idades compreendidas entre os cinco e nove anos, este projeto tem como base um jogo 3D para as plataformas Windows, Mac OS X e Linux, controlado com os movimentos dos membros superiores através do dispositivo Leap Motion. Através do controlo de um avião, a criança descobre várias ilhas e desbloqueia componentes do mesmo, alcançando os diversos bónus e checkpoints ao longo de cada percurso. Ao terapeuta são apresentados gráficos com dados obtidos pelo dispositivo aquando do momento lúdico da criança que permitem acompanhar a sua evolução a cada nível. O sucesso no cumprimento dos objetivos do projeto permitiu confirmar a utilidade da aplicação na intervenção e avaliação do público-alvo.

The Total fiscal cost of indirect taxation: an approximation using Catalonia's recent input-output table

In this note we quantify to what extent indirect taxation influences and distorts prices. To do so we use the networked accounting structure of the most recent input-output table of Catalonia, an autonomous region of Spain, to model price formation. The role of indirect taxation is considered both from a classical value perspective and a more neoclassical flavoured one. We show that they would yield equivalent results under some basic premises. The neoclassical perspective, however, offers a bit more flexibility to distinguish among different tax figures and hence provide a clearer disaggregate picture of how an indirect tax ends up affecting, and by how much, the cost structure.

Redescription and resurrection from synonymy, of Aedes (Ochlerotatus) Rhyacophilus Costa Lima, 1933

Aedes (Ochlerotatu) rhyacophilus Costa Lima i resurrected from the synonymy with Aedes (Ochlerotatus) scapularis (Rondani). Lectotype and paralectotypes are designated Larval, pupal and both sexes of adult stages are redescribed and illustrated. Bionomics include a picture of a brreding place. Diagnostic characters for distinguishing rhyacophilus from other species of the Scapularis Group are provided. Some data about known distribution are presented.

General Interaction Picture from Action Principle for Mechanics

In this paper we consider a general action principle for mechanics written by means of the elements of a Lie algebra. We study the physical reasons why we have to choose precisely a Lie algebra to write the action principle. By means of such an action principle we work out the equations of motion and a technique to evaluate perturbations in a general mechanics that is equivalent to a general interaction picture. Classical or quantum mechanics come out as particular cases when we make realizations of the Lie algebra by derivations into the algebra of products of functions or operators, respectively. Later on we develop in particular the applications of the action principle to classical and quantum mechanics, seeing that in this last case it agrees with Schwinger's action principle. The main contribution of this paper is to introduce a perturbation theory and an interaction picture of classical mechanics on the same footing as in quantum mechanics.

Catálogo de las algas bentónicas (con exclusión de las diatomeas) de la costa catalana

Aquest treball és un intent d´actualitzar i sistematitzar les dades algològiques que es posseeixen referents al nostre país. Aquestes dades han estat obtingudes de la bibliografia existent, incloent-hi també nombroses observacions personals inèdites. La sistemàtica utilitzada ha estat, bàsicament, la proposada per PARKE i DIXON (1976). La distribució geogràfica de les espècies s'especifica en funció del reticle UTM. En aquest moment són 403 (28 Cyanophyta, 220 Rhodophyta, 69 Phaeophyta, 85 Chlorophyta i 1 Chrysophyta) les espècies que es coneixen a les costes del Principat.

Esquema morfológico de la costa catalana

Presentamos en esta nota un esquema descriptivo de las formas litorales de la costa catalana, elaborado mediante la consulta de las fotografas areas y de trabajos de diversos autores. Los criterios establecidos para la clasificacin de las formas han sido lo ms elementales posible, a fin de obtener un esquema bsico de trabajo para investigaciones posteriores de cualquier tipo.
