25. Geocronology, isotopic geochemistry and geochemical of the dioritic-granitic plutonism between Lavras and Conselheiro Lafaiete: implicatins to paleoproterozoic evolution of Mineiro Belt central part / Geocronologia, geoquímica isotópica e litoquímica do plutonismo diorítico-granítico entre Lavras e Conselheiro Lafaiete: implicações para a evolução paleoproterozóica da parte central do Cinturão Mineiro
The study area is located in the southern border of the São Francisco Craton, Mineiro Belt. This portion comprises part of the Sul Mineira Province. In this context occurs medium to high metamorfic grade Archean and Paleoproterozoic terrains mosaic and granite-greenstone associations. The plutonic bodies, studied in this work, make part of volumous paleopro

26. INVESTIGAÇÃO DE COMPLEXOS BINUCLEARES DE K+ E CU(II) COM LIGANTES 1,3-DIARILTRIAZENIDOS SIMÉTRICOS / COMPLEXES INVESTIGATION BINUCLEARES OF K+ And Copper(II) WITH 1,3-DIARYLTRIAZENES AS LIGANDS SYMMETRICAL
At work present it synthesized and determined itself the molecular structure of a copper complex (II) and another of potassium in which both involve triazenides ligands monocatenados previously deprotonated. The reaction between hydroxide of solid potassium and it pre-ligand 1,3-bis(4-nitrophenyl)triazene, in methanol, originated the triazenide complex [K(O2

27. A mística no cotidiano do MST: a interface entre religiosidade popular e política / The mistica in everyday life of the MST: The Interphases Between Popular Religious and Politics
This study intends to describe and analize the main characteristics and functions of the mistica in everyday life of the MST. In our study, beginning with the literature that focuses on the mistic in other areas of knowledge and then, specifically, we consulted a bibliography that deals with the mistica in the MST. We bring to our study historical and theore

28. Reflexões, isometrias e arvores
We define a reflection in a graph as an involutive automorphism whose set of fixed points is a complete geodesic. Using this concept, we prove that the product of two such reflections is an eliptic isometry if and only if its sets of fixed points has nonempty intersection. Moreover, for the case of a regular tree of valency 4k, we prove that the topological

29. Analise de simulação de cruzamento semaforizado
Conflicts emerge from the competition between elements participating in the circulation system, when these achieve severe degree traffic accidents occur. These accidents should be analyzed trom various points view so that its comprehension may indicate corrective measures. This work aims to identify the influence of dynamic publicity panels in the perception

30. O contexto lito-estrutural das mineralizações auriferas na região de Pocone-MT
The Poconé region represents an important gold province located in the Mato Grosso State. This province is hosted in a Neoproterozoic metasedimentary sequence, which constitute the Cuiabá Group. This research is dedicated to a detailled study of the tectonic structures of this region, and the main target is to present a descriptive and qualitative structur

31. Regiões organizadoras do nucleolo (NORs) em celulas mesoteliais e carcinomatos as de liquidos caritarios : auxilio no diagnostico diferencial de exames citologicos
The AgNOR reaction was performed on effusions and peritoneal washings, and the silver dots counted on normal or reactive mesothelial cells versus carcinomatous cells, ascertained by previsous HE staining. The mean values were 1.71 for the former (n=49) and 3.98 for the latter (n=25). The intersection between the two group distributions was 2,66, leaving a ch

32. Existence of a nonarithmetic lattice in SU(2,1)
The proof of the well-known conjecture that lattices in groups of R-rank greater than 1 are arithmetic has raised speculation about the existence of nonarithmetic lattices in the R-rank 1 group SU(n,1), n > 1. This paper presents an example of such a lattice Γ1. Γ1 consists of the intersection with SU(2,1) of a group Γ generated by three complex reflectio

33. Portal triad clamping or hepatic vascular exclusion for major liver resection. A controlled study.
OBJECTIVE: The authors compared operative course of patients undergoing major liver resections under portal triad clamping (PTC) or under hepatic vascular exclusion (HVE). SUMMARY BACKGROUND DATA: Reduced blood loss during liver resection is achieved by PTC or HVE. Specific complications and postoperative hepatocellular injury mediated with two procedures ha

34. Crossmaps: Visualization of overlapping relationships in collections of journal papers
A crossmapping technique is introduced for visualizing multiple and overlapping relations among entity types in collections of journal articles. Groups of entities from two entity types are crossplotted to show correspondence of relations. For example, author collaboration groups are plotted on the x axis against groups of papers (research fronts) on the y a

35. Structure of Concanavalin A at 4.25-Ångström Resolution
An electron density map produced by x-ray diffraction analysis of concanavalin A has been calculated to 4.25 Å from data of three isomorphous heavy atom derivatives. The crystals are orthorhombic, with unit-cell dimensions of 63.1, 87.0, and 89.2 Å for a, b, and c, respectively. The space group is I222, with eight asymmetric units per unit cell. The crysta

36. Adjoint modular Galois representations and their Selmer groups
In the last 15 years, many class number formulas and main conjectures have been proven. Here, we discuss such formulas on the Selmer groups of the three-dimensional adjoint representation ad(φ) of a two-dimensional modular Galois representation φ. We start with the p-adic Galois representation φ0 of a modular elliptic curve E and present a formula ex
