Near-infrared reflectance spectroscopy as a tool for breeding Andropogon gayanusKunth for forage quality.

Abstract: The objective was to investigate the usefulness of Near Infrared Spectroscopy (NIRS) to predict bromatological traits concentrations of gamba grass (Andropogon gayanus Kunth). Random samples from different plant genetic backgrounds, climatic conditions over years, experimental sites, and harvests were used for spectral reading and reference analysis. Partial Least Square (PLS) regressions were used for developing the models with 239 samples for calibration and 119 for external validation. Crude Protein, Ash, and Dry Matter models had R2= 0.91, 0.91, and 0.90 and low standard errors of calibration (SEC) of 8.7, 3.8, and 5.5 g.kg-1 , respectively. Neutral and Acid Detergent Fibers, and Organic Matter had R2 = 0.85, 0.88, and 0.89 and SEC valuesof10.2, 9.4, and 7.9 g.kg-1 , respectively. In vitro digestibility of dry matter had R2= 0.79 and SEC 28.0 g.kg-1 . Acid Detergent Lignin had a poor fit with R2= 0.36.A high correlation between NIRS predictions and wet lab data was observed. Models were adequate and accurate for predicting all bromatological traits but ADL. Significative differences among 51 half-sib families were detected for quality traits predicted throughPLS models. NIRS can be effectively used in gamba grass breeding programs for selecting superior forage quality genotypes. -------------------------------------------------------------------------------------------------------------------------

Bem-morar em São Paulo, 1880-1910: Ramos de Azevedo e os modelos europeus

Domestic architecture achieves a great impulse in the second half of XIXth-century. From Europe to the whole world, models are conformed to the new social order and spread as industrialization takes command. Dwelling becomes the main concern among architects. New concepts are developed for the ideal house for 011 social strata: working class, middle-class, bourgeoisie. This essay traces the introduction in São Paulo of European formal patterns and principies Ihygiene, salubrity, comfort, social and domestic rites, social visibility) through the activity of F. P. Ramos de Azevedo! 1851-19281. The main projects he conceived for the local bourgeoisie are analysed.A arquitetura doméstica tem um grande impulso no século XIX. Da Europa são difundidos, para todo mundo, os modelos conformados à nova ordem social e à industrialização. A residência se transforma numa preocupação central dos arquitetos. Desenvolvem-se novos conceitos para casa ideal para todas as camadas sociais: operários, classe média, burguesia. Este artigo retrata, em São Paulo, a introdução de padrões formais e princípios (de higiene, salubridade, conforto, ritos sociais e domésticos, as aparências). a partir da atividade de F. P. Ramos de Azevedo (1851-19201. Analisam-se os principais projetos que ele desenvolveu para a burguesia local

Sources of alpha-, beta-, gamma-, delta- and epsilon-carotenes: a twentieth century review

Since humans cannot synthesize carotenoids, they depend upon the diet exclusively for the source of these micronutrients. It has claimed that they may alleviate chronic diseases such as cancers. The present communication constitutes a global review of the scientific literature on plants and others organisms that biosynthesize carotenoids, which include the series alpha-, beta-, gamma-, delta- and epsilon-carotenes. The results of the literature survey lists more than five hundred sources
