A portion of the dietary nutrients is excreted due to the presence of antinutritional factors in some ingredients. This study aimed to determine the total and ileal digestibility coefficients of crude protein, as well as the passage rate of diets with different chemical compositions, supplemented or not with an enzymatic complex, in broiler chickens. No effect of the enzymatic complex was observed on the crude protein digestibility coefficient (P>0.05). However, the ileal digestibility coefficients of crude protein showed significant differences (P<0.05) within each group (with or without enzyme supplementation). The control treatment with the enzymatic complex presented a lower ileal digestibility coefficient of crude protein (P<0.05) compared to the control treatment without supplementation. The passage rate did not differ between treatments (P>0.05). It was concluded that the inclusion of the enzymatic complex, composed of calcium carbonate, Yucca extract, protease, phytase, and cellulase, in vegetable-based diets for broiler chickens did not affect digestibility coefficients or passage rate. Keywords: poultry farming, enzyme additives, nutrition, crude protein

Este artigo discutirá as ideias de verdadeiro e falso self de Winnicott. O objetivo é apresentar como se compõe a estruturação desses tipos de selves e uma poesia chamada Velho Órfão, é usada como meio de ilustrar e discutir o sentimento de alguém constituído em uma estrutura de falso self. As implicações clínicas dessa questão são discutidas. Conclui-se que o processo de resgate do verdadeiro self é trabalhoso, mas possível, se o terapeuta estiver engajado nesse projeto com seu paciente, disponível a se comunicar com ele em uma dimensão existencial.

This article aims to demonstrate the philosophical roots of Arthur Schopenhauer in the sensualist movement. To this end, I propose distancing him from claims of an unrestricted Romantic influence, without dismissing the influx from this movement, which reflects the spirit of his time. The focus is to associate the German philosopher with one of the movements that, though smaller, helped propel the Romantic period: Sensualism. This movement, which attributes all functions of the soul and, consequently, all knowledge to sensations, as presented in Étienne Bonnot de Condillac's Treatise on Sensations – often regarded as the precursor of sensualism – exerted significant influence over French philosophers, among whom were some of his students and disciples who later sought to expand and refine the doctrine. The hypothesis of a sensualist influence on Schopenhauer will be supported through two theses: 1) the transition between intellect and will, presented in his magnum opus, The World as Will and Representation, which will be related to French physiology; and 2) his brief treatise on education, found in Parerga and Paralipomena, which will be associated with Johann Pestalozzi's pedagogy.

O presente artigo tem como objetivo analisar como o conceito de antinatalismo – isto é, uma visão filosófica que defende a ideia de que é melhor que os humanos parem de trazer novas vidas ao mundo, ou que teria sido melhor não termos sido trazidos à existência – e, mais especificamente, o antinatalismo de David Benatar, se alinham à vertente metafísica do pessimismo schopenhaueriano, presente no Tomo I de O Mundo como Vontade e Representação e também nos Suplementos. Ao fazer isto, não será intenção deste trabalho a pressuposição de que as vertentes do pessimismo de Schopenhauer sejam, necessariamente, antinatalistas. Antes, tem-se como motivação demonstrar o que há do pessimismo metafísico schopenhaueriano no antinatalismo de Benatar que, por ser diferente de outras visões antinatalistas, é aqui adjetivado como “benatariano”, e, por conseguinte, o que há na posição do filósofo sul-africano que pode ser justificado pela metafísica de Schopenhauer.

This work aims to analyze the action of the poetic or inventive imaginative faculty (Dichtungsvermögen) in the Transcendental Deduction of the Categories, in the first edition of Kant's Critique of Pure Reason (1781), and to examine the emphasis that this author attributes to it in his Anthropology. This work defends the thesis that this capacity of the imaginative faculty would have a fundamental role in the development of the subjective deduction presented by Kant in the first edition of his Critique of pure reason, indicating, as it would make it possible to consider from its functioning a theory of psychological judgments, however, we will emphasize that such a possibility would be limited in the Critique, a fact that we consider to add its field of action and investigation to Anthropology, which would characterize this last work as a fertile field for psychological action and investigation.

This paper is part of a series in which we had worked in the last 6 months, and, specifically, intend to investigate the notion of timbre through the ecological perspective proposed by James Gibson in his Theory of Direct Perception. First of all, we discussed the traditional approach to timbre, mainly as developed in acoustics and psychoacoustics. Later, we proposed a new conception of timbre that was born in concepts of ecological approach. The ecological approach to perception proposed by Gibson (1966, 1979) presupposes a level of analysis of perceptual stimulated that includes, but is quite broader than the usual physical aspect. Gibson suggests as focus the relationship between the perceiver and his environment. At the core of this approach, is the notion of affordances, invariant combinations of properties at the ecological level, taken with reference to the anatomy and action systems of species or individual, and also with reference to its biological and social needs. Objects and events are understood as relates to a perceiving organism by the meaning of structured information, thus affording possibilities of action by the organism. Event perception aims at identifying properties of events to specify changes of the environment that are relevant to the organism. The perception of form is understood as a special instance of event perception, which is the identity of an object depends on the nature of the events in which is involved and what remains invariant over time. From this perspective, perception is not in any sense created by the brain, but is a part of the world where information can be found. Consequently, an ecological approach represents a form of direct realism that opposes the indirect realist based on predominant approaches to perception borrowed from psychoacoustics and computational approach.

The purpose of this paper is to question the legitimacy of the intervention that determines Kant's philosophy over Maine's philosophy of Biran. We will maintain, in this research, that Biranism is not a kind of Kantism and that the French philosopher's oppositions to the German philosopher are more striking than the apparent compatibility between them. To prove this proposition, we will demonstrate that the Biranian theses are essentially Biranian, contesting the words of our Lachelier that “Maine de Biran is Kant”, and also that Maine de Biran was never a Kantian in strict sense, following a path opposite to that of the German philosopher, distancing himself from his philosophy and from any determinant influence of Kant.

This study explores and presents some of correspondences of Kant, how to use to touch up or follow the schedule of the ideas that have established the structure, problems and receipt of Pure Reason critique of Kant. Our focus in this exhibition is to demonstrate that the development issues involving Critique of Pure Reason. For this, we will make a chronological return starting this exhibition from the 1760s; advancing to the inaugural dissertation of 1770, this until the first edition of criticism, and finally to the last correspondence on the same matter in the years 1797.

Este trabalho tem por objetivo demonstrar elementos argumentativos apresentados por Kant em seu trabalho final: Opus Postumum, que comprovaria a tentativa de Kant em desenvolver ali uma dedução, contudo, demonstraremos que esta dedução em desenvolvimento no Opus articula elementos que a aproximaria significativamente da dedução transcendental de 1781. Com isto, temos a comprovação que no Opus há uma reavaliação da parte subjetiva da dedução transcendental exposta na primeira edição da Crítica, o que incide numa retomada desta investigação subjetiva por Kant, buscando nesta a tentativa de preenchimento da lacuna que ele considera impedir o fechamento de seu sistema.

The notion of normal proof theory, and yet it has been somewhat neglected by the systems of equational logic. The intention here is then to show the normalization procedure for the equational logic of the Labelled Natural Deduction system . With this we believe we are making a step towards filling a gap in the literature on equational logic. Besides presenting a normalization procedure for the LND equational fragment, we employ a new method to prove the normalization theorems for equational logic: proof transformation by rewriting, based on a algebraic calculus on the 'rewrite reasons'

The geometric system of deduction called N-Graphs was introduced by de Oliveira in 2001. The proofs in this system are represented by means of digraphs and, while its derivations are mostly based on Gentzen's sequent calculus, the system gets its inspiration from geometrically based systems, such as the Kneales' tables of development, Statman's proofs-as-graphs, Buss' logical flow graphs, and Girard's proof-nets. Given that all these geometric systems appeal to the classical symmetry between premises and conclusions, providing an intuitionistic version of any of these is an interesting exercise in extending the range of applicability of the geometric system in question. In this article we produce an intuitionistic version of N-Graphs, based on Maehara's LJ' system, as described by Takeuti. Recall that LJ' has multiple conclusions in all but the essential intuitionistic rules, e.g., implication right and negation right. We show soundness and completeness of our intuitionistic N-Graphs with respect to LJ'. We also discuss how we expect to extend this work to a version of N-Graphs corresponding to the intuitionistic logic system FIL (Full Intuitionistic Logic) of de Paiva and Pereira and sketch future developments.

Neste artigo, será deliberada a forma como a moral da existencialização começa por se formar nos escritos kierkegaardianos, principalmente aqueles que se restringem ao livro A alternativa e como a conceituação de tais princípios éticos relaciona-se formando um corpus sapiencial, aludindo-se, primariamente, à ética prudencial kantiana, em voga no século XIX.In this article, shall be decided how the moral´s fact existential begins to form in a Kierkegaardian writings, especially those confined to the book The alternative, such as the concept of ethical principles related to form a corpus of wisdom, alluding to, primarily, prudential kantian ethic, in vogue in the XIX century
