3D-Echtzeitrendering mit Ventuz

Ziel der vorliegenden Bachelorarbeit ist es zu erläutern, wie 3D-Echtzeitrendering funktioniert und wie dies mit der Software Ventuz Designer Version 4 von der Firma Ventuz Technology AG durchgeführt wird. Sie ermöglicht dem Anwender, ohne Programmierkenntnis, auf die Funktionen der Grafikkarte über DirectX zuzugreifen. Es wird Grundwissen zum Thema computer-gestützte Bildgenerierung vermittelt, um ein besseres Verständnis für die dahinterliegenden Prozesse und Verfahren zu entwickeln.

Nutrição mineral de leguminosas tropicais VII: recrutamento de micronutrientes pela cunhã (Clitoria ternatea L.)

Com a finalidade de obter dados acerca do recrutamento de micronutrientes, a leguminosa foi cultivada em um Latossolo Vermelho Escuro Orto, série "Luiz de Queiroz" em Piracicaba, SP. A coleta de amostras constituidas por plantas rasteiras, foi efetuada de 15 em 15 dias a partir dos 41 dias após a semeadura. Após cada amostragem, as plantas foram separadas em folhas, caules, flores e vagens. Em cada época nas diferentes partes da planta foram determinadas as concentrações de boro, cobre, ferro, manganês e zinco. Os autores consideram que: - O período de 86 dias após a semeadura, sob o ponto de vista dos minerais, é aquele para o aproveitamento da planta como forrageira; - Aos 86 dias após a germinação, a concentração dos micronutrientes na folha é de 41 ppm B; 8 ppm Xu; 402 ppm Fe; 94 ppm Mn e 45 ppm Zn; - Aos 86 dias após a germinação, o acumulo de micronutrientes por planta é de 390 mg B; 81 mg Cu; 3404 mg Fe; 751 mg Mn; 402 mg Zn; - Para uma população teórica de 825.000 plantas por hectare, a extração dos micronutrientes é na ordem de 322 g B; 67 g Cu; 2808 g Fe; 620 g Mn e 332 g de Zn.

Padrão reprodutivo de Elachistocleis bicolor (Anura, Microhylidae) na Serra da Bodoquena, Mato Grosso do Sul, Brasil

The reproductive pattern of Elachistocleis bicolor (Guérin Méneville, 1838) was studied at Serra da Bodoquena, from October 2000 to September 2001. Reproduction occurred in the wet season (October to April) and was correlated to high continuous pluviometric precipitation. The species presents sexual size dimorphism, with females larger than males. The number of mature eggs per ovary was 620 ± 251 (n=39) and mature eggs measured 1.15 ± 0.30 mm (n=40). Elachistocleis bicolor presented significant relations between snout-vent length and number of mature eggs (n=39; r²=0.25; p=0.001), individual weight and number of mature eggs (n=41, r²=0.30; p=0.002), snout-vent length and ovarian weight (n=35; r²=0.47; p<0.01), and individual weight and ovarian weight (n=36; r²=0.55; p<0.01). Weight and volume are better to study size-fecundity relationships than snout-vent length. The females invested 22.7 ± 6.3 % (n=35) of their weights in reproduction and the variance associated to this variable was high, related to the reproductive mode of the species.

Abundance of Conepatus chinga (Carnivora, Mephitidae) and other medium-sized mammals in grasslands of southern Brazil

Between January 2007 and December 2010, the abundance of medium-sized mammals was studied, with special focus on the Molina's hog-nosed skunk, Conepatus chinga (Molina, 1782), at four locations in southern Brazil. In this study, transect line methodology was used to obtain data for Distance Analyses. Transects were traveled by car at night, searching with spotlights along the edges of secondary roads in agricultural landscapes. Along 1,811 km, we obtained 620 observations of 20 mammal species. The most common species was the exotic European hare, Lepus europaeus (Pallas, 1778); the highest abundance estimated for South America was observed in one of the study areas, where its density was estimated as 32 individuals/km². Carnivores were the most commonly recorded mammals, represented by 10 species and comprising 51% of all observations. Molina's hog-nosed skunk occurred in all study areas, but occurred in sufficient numbers to obtain density estimates in only two of the areas. We estimated 1.4 to 3.8 individuals/km², in the first density estimate made by the transect method for a member of Conepatus in the Neotropics. These values are similar to those estimated for North American species of Mephitidae. In Brazil, C. chinga is apparently more abundant in the Pampa biome than in the grasslands of the Atlantic Forest. For two other carnivores, Lycalopex gymnocercus (Fisher, 1814) and Cerdocyon thous (Linnaeus, 1766), we estimated preliminary densities that were similar to those previously cited for different regions.

Contractions in the 2-wasserstein lenght space and thermalization of granular media

An algebraic decay rate is derived which bounds the time required for velocities to equilibrate in a spatially homogeneous flow-through model representing the continuum limit of a gas of particles interacting through slightly inelastic collisions. This rate is obtained by reformulating the dynamical problem as the gradient flow of a convex energy on an infinite-dimensional manifold. An abstract theory is developed for gradient flows in length spaces, which shows how degenerate convexity (or even non-convexity) | if uniformly controlled | will quantify contractivity (limit expansivity) of the flow.

On dictatorship, economic development and stability

This paper aims to account for varying economic performances and political stability under dictatorship. We argue that economic welfare and social order are the contemporary relevant factors of political regimes' stability. Societies with low natural level of social order tend to tolerate predatory behavior from dictators in exchange of a provision of civil peace. The fear of anarchy may explain why populations are locked in the worst dictatorships. In contrast, in societies enjoying a relative natural civil peace, dictatorship is less likely to be predatory because low economic welfare may destabilize it.

Síntesi i caracterització de nanopartícules d'òxid de cobalt

L’objectiu d’aquest projecte és sintetitzar i caracteritzar nanopartícules d’òxid de cobalt. Ens interessa estudiar diferents isomorfes de monòxid de cobalt (CoO) ja que són materials nous i se’n desconeixen les propietats; en algunes investigacions s’intueix un comportament antiferromagnètic la qual cosa les fa especialment interessants per aplicacions magnètiques.
