Abstract: mini blast furnaces are reactors that traditionally produce pig iron from charcoal using granular ore with some agglomerate substitution. this work proposes metallic burden replacement by self-reducing agglomerates and reutilization of cleaned top gas injected into the shaft of the mini blast furnace where charcoal or small coke from a large blast furnace are used as the reducing agent. this technology was evaluated using a previously validated, blast furnace computational code based on the transport phenomena. several scenarios combining the charging of the furnace with self-reducing agglomerates and reutilization of cleaned top gas were simulated. based on the simulation results, it can be concluded that up to 45% of the metallic burden could be replaced by self-reducing agglomerate combined with the reutilization of the top gas. the best conditions indicated an increase in productivity of around 8% with charcoal as the reducing agent. results showed that decreases of 30% and 40% of the reducing agent could be achieved for operations with charcoal and small coke, respectively.

Abstract: RESUMO - O experimento foi conduzido com objetivo de avaliar as perdas de forragem e a acumula o de liteira em uma pastagem de capim-Tanzania (Panicum maximum Jacq cv. Tanzania-1 ) manejada sob diferentes alturas. Os níveis de altura (tratamentos) estudados foram: 29,8; 32,0; 47,1; 51,5; 57,9; 62,7; 72,6 e 80,0 cm, em um delineamento completamente casualizado e com duas repeti es. As taxas de acúmulo e acumula o de liteira e as perdas de forragem foram iguais em todas as alturas. A porcentagem de forragem senescente foi influenciada de forma quadrática pelos níveis de altura. Os resultados indicam que foram altos os níveis de acumula o de liteira e as perdas de forragem, em média, 38,9 kg/ha/dia de MS e 2179 kg/ha de MS, respectivamente. Devido à possibilidade de se reduzirem a persistência da pastagem e a modifica o da estrutura das plantas, recomenda-se n o utilizar pastagens de capim-Tanzania em alturas próximas ou iguais a 20 e 80 cm, sob lota es contínuas.
Contingência e análise infinita em Leibniz
Pinheiro, Ulysses;
Kriterion: Revista de Filosofia , 2001, DOI: 10.1590/S0100-512X2001000200004
Abstract: leibniz says in various occasions that infinite analysis is the key concept to explain the compatibillity of determinism and contingence. it is not evident, however, why the analogical use of a mathematical concept, such as infinitesimal calculus, could solve this ontological problem, nor in what sense one should understand such analogy. the aim of this paper is to elucidate these two points.
Omiss?es

Abstract: at first sight, actions and omissions do not share the same properties. some authors hold that an illustration of this assimetry is causality: actions must be explained as the instantiation of a causal relation between an agent and certain facts, while omissions seem to have to be explained as the absence of causal relations between a person and the relevant facts. in this paper, i will show that actions and omissions are, contrary to appearances, simetrical regarding the attribution of genuine causality.
A "doen?a dos eruditos" e a triangularidade da ideia de triangulo: uma análise do conceito de espa?o no tratado de Hume
Pinheiro, Ulysses;
Kriterion: Revista de Filosofia , 2010, DOI: 10.1590/S0100-512X2010000100004
Abstract: hume's analysis of the concept of space in the treatise of human nature commits him to a series of positive assertions on its nature and on the content represented by its idea: space is finitely divisible, and its idea is composed of colored or tactile non-extended points, which leads him to conclude that the idea of space is itself spatial. these assertions seem to commit hume to an idealistic theory of space. in this paper, i propose to elucidate hume's arguments for his positive theses and to examine his commitment to idealism through a characterization of the nature of treatise's propositions.

Abstract: introduction: surgical treatment of rectal cancer has undergone great technical refinement after total mesorectal excision. the possibility of laparoscopic approach still remains controversial. thus, an updated review of the matter is relevant to help to guide physicians in surgical treatment. method: it was done an extensive review of papers on databases available through medline / pubmed, lilacs and scielo crossing the following keywords: colorectal cancer, laparoscopic surgery, surgery. conclusion: to date, there still remains a matter of controversy whether the treatment of rectal cancer should be routinely performed by laparoscopy. there are no published data that support the achievement of minimally invasive total mesorectal excision for rectal cancer treatment outside the research protocol, notably a lack of survival rates and local recurrence with at least five years of follow-up.
