Paranaguá, Antonina e Curitiba, início do século XIX: reconstituindo espaços e a lógica de sua organização social

This paper is to develop a methodology to characterize the spatial distribution in the early nineteenth century, the urban residents enrolled in the Décima of Paranaguá, Antonina and Curitiba, three villages in southern province of São Paulo. Here are the problems faced and decisions made, almost always temporary and arbitrary. The result reached hypothetical plants of subdivisions and urban streets of those towns. From a database - developed mainly with the information Lista Nominativa de Habitantes - it was possible to characterize residents enrolled in the books of property tax Décima. Spatialising thematic data in plants, where they lived was possible to perceive the social group, your choices (or lack thereof), or realize their preferred sites, but not exclusive housing.O objetivo desse artigo é desenvolver uma metodologia para caracterizar a espacialização, no início do século XIX, dos moradores arrolados nas décimas urbanas de Paranaguá, Antonina e Curitiba, três vilas do sul da capitania de São Paulo. Apresentamos aqui os problemas enfrentados e decisões tomadas, quase sempre provisórias e arbitrárias. O resultado chegou a plantas hipotéticas dos loteamentos e arruamentos urbanos daquelas vilas. A partir de um banco de dados - elaborado principalmente com informações das Listas Nominativas de Habitantes -, foi possível caracterizar os moradores arrolados nos livros de imposto predial de Décima. Espacializando esses dados em plantas temáticas, foi possível perceber onde moravam os grupo sociais, suas escolhas (ou a falta delas), ou seja, perceber seus locais preferenciais, mas não exclusivos, de habitação

Fermentation parameters, quality and losses in sugarcane silages treated with chemical additives and a bacterial inoculant

The objective of this trial was to evaluate chemical additives and a bacterial inoculant on the inhibition of alcoholic fermentation and reduction of losses in sugarcane silages. Treatments were (doses on a fresh forage basis): without additive (control); urea (10 g/kg); urea (5 g/kg) + sodium benzoate (0.5 g/kg); sodium benzoate (1 g/kg); urea + ammonium sulfate in a 9:1 relation (10 g/kg); Lactobacillus buchneri (5 × 10(4) cfu/g). Silages were produced in 10.16- × 30-cm PVC tubes, provided with tight lids adapted with Bunsen valves for gas losses quantification. Minisilos were opened 139 days after ensiling. Ethanol content (227 g/kg dry matter - DM) and total DM loss (30%) were high in the control silage. All additives, except benzoate, decreased ethanol concentration in silages. Inoculation with L. buchneri increased acetic acid content in the silage, resulting in a 41% reduction in ethanol content and the lowest gas loss among treatments (15.2%). There was synergistic effect between additives for the combined use of urea and benzoate. Silage treated with urea + ammonium sulfate has higher content of total digestible nutrients than the silage treated with urea exclusively
