37. Estudo do processo de cristalização de soluções impuras de sacarose por resfriamento
The objective of this work was to study the crystallization kinetics of impure sugarcane sucrose solutions by cooling, prepared as of VVHP and VHP raw sugars, sugarcane syrup and for PP-45 high purity granulated sugar (reference sample), as a part of technology development work for high purity sugar production. The applied methodology was that one proposes b

38. (Re)constitutição do ideario de futuros professores de matematica num contexto de investigação sobre a pratica pedagogica
The purpose of this research is to answer the question: how do the pedagogical ideary and the teaching practice of pre-service teachers of Mathematics (re)constitute themselves in a process of education mediated by action, reflection and investigation about the pedagogical practice? Thus, the objectives conducting this study are: first, to identify the const

39. Inexistencia de blow-up hiperbolico simples para a equação quasi-geostrofica
Nonexistence of simple hyperbolic blow-up for the quasigeostrophic equation. This master dissertation deals with the quasigeostrophic equations, a system of integro-differential equations that has been proposed as a model for the process of large-scale front formation in the atmosphere. These equations have a structure that resembles the system of two dimens

40. A congregação do Colégio Pedro II e os debates sobre o ensino de matemática
Colégio Pedro II was criated to be a model to others country colleges, in the XIX centurys first half). College teachers had a meet to discuss, vote and aprove changes: the Congregation of Colégio Pedro II. So hapenned with changes and reforms would be practice in all country classes of math. These discussions relationated with contends and metodology are

41. Ajuste de modelos lineares aplicado a maquinas rotativas
Generally, when talking about the design procedure and simulation of rotors, the approaches and inherent hypotheses to the applicable mathematical models to such types of machines bring numerical responses different from that obtained in experimental mensurements. The models updating theory has for objective to minimize such kind of errors through techniques

42. P/NP, and the quantum field computer
The central problem in computer science is the conjecture that two complexity classes, P (polynomial time) and NP (nondeterministic polynomial time—roughly those decision problems for which a proposed solution can be checked in polynomial time), are distinct in the standard Turing model of computation: P ≠ NP. As a generality, we propose that each physic

43. L and ε functions for GSp(4) × GL(2)
The construction of L functions for automorphic cuspidal representations of GSp(4, A) × GL(2, A) with a Whittaker model has been given by Novodvorsky [Novodvorsky, M. (1979) Proc. Symp. Pure Math. 33 (2), 87-95]. In this paper, we prove that this L function has nontrivial poles if and only if the representation of GSp(4, A) is a lifting from split O4. We al

44. F-Deformations and F-Tractions
Let Mn be a compact, connected topological manifold and F a continuous mapping of Mn into R that is “topologically nondegenerate” in the sense of (Morse, M. (1959) J. d'Analyse Math., 7, 189-208). Let c be a value of F and set Fc = {p∈Mn|F(p) ≤ c}. The topological critical points of F on Fc are finite in number and can be related to the invariants of
