Metabolizable energy levels affect the productive performance and carcass quality of meat quails, as well as impacting diet costs. The aim was to determine the metabolizable energy (ME) requirement for European quails (Coturnix coturnix coturnix) from 1 to 14 days of age and from 15 to 35 days of age, aiming to evaluate performance and influence on carcass composition. Five treatments with 6 replicates, 12 animals per replicate, totaling 360 animals in the experiment, were used, with energy levels in the diet of 2700, 2800, 2900, 3000, and 3100 kcal from 1 to 14 days of age, and levels of 2850, 2950, 3050, 3150, and 3300 kcal from 15 to 35 days of age. Total carcass weight, breast, wing, back, fat, liver, heart, and gizzard weights were determined, both absolute and relative to the carcass (%). It was concluded that the best metabolizable energy level in the diet from 1 to 14 days of age is 3000 kcal/kg of ME and that the best metabolizable energy level in the diet from 15 to 35 days is 3150 kcal/kg of ME on diet. Keywords: performance; carcass; levels.

Despite its great speculative relevance and despite the fact that it is the very foundation of the Hegelian system, The Science of Logic by G. W. F. Hegel is practically an illegible book nowadays. Even for Germans it is a difficult reading. Other books by Hegel (except for the Encyclopedia) are reasonably readable. This is not the case of The Science of Logic. Almost all technical terms used by Hegel are defined by a conceptual network, in which the components are themselves related to one another. That is the reason for the difficulty of finding a reading guide to direct the reader from one chapter to the next. Initially, the authors of the present paper try to translate Hegel’s typical language into usual English, even if some of the richness of the original text is lost. In a second step, they attempt to formalize what has been translated. There is no intention of keeping fidelity to Hegelian orthodoxy; on the contrary, the authors attempt to correct everything they think is an error in the Hegelian system. Key words: dialectics, Hegel, formalization.

As interrogações podem ser definidas como a disjunção de todas as suas possíveis respostas. Assim definidas, elas nada dizem e são equivalentes às leis lógicas. Basicamente, as interrogações, conforme a variável questionada, podem ser enunciativas, individuais ou predicativas. Fundamentalmente as interrogações têm duas possíveis respostas ; mas as individuais e as predicativas, por uma dessas respostas ser uma particularização, podem ser consideradas interrogações de múltiplas possíveis respostas.
