1. Fragmentation Reactions of Rhodamine B and 6G as Revealed by High Accuracy Orbitrap Tandem Mass Spectrometry
Correct interpretation of mass spectra is essential to our understanding of the ion chemistry occurring in the gas phase inside mass spectrometers and for constructing a solid knowledge from which mass spectrometry (MS) data of novel molecules will be interpreted. Assignments of product ions leading to incorrect dissociation mechanisms can also be dangerous

2. Aproveitamento dos resíduos lignocelulósicos gerados no Polo Moveleiro de Ubá para fins energéticos
The furniture industry in Brazil represents an important segment for the national economy, especially for the expressive number of jobs opportunities generated. In the last two decades, the sector went through great changes, focused in the increase of production capacity and productivity, as well as in the higher product quality. However, the furniture indus

3. Coexistir na fronteira: notas de um antropólogo sobre a trajetória de um grupo de jovens em meio a uma guerra entre a comunidade e o tráfico de drogas
On behalf of an anthropology that looks for to analyze the can-resistance relationships starting from the coexistence among the several components inside of different urban territories and that he seeks to do to emerge the several present violence forms in the daily relationships is that I intended to accomplish this research. In my entitled research of Mast

4. Investigação das características tribológicas e ambientais de termoplásticos de engenharia especiais para uso em materiais de atrito. / Investigation of tribological and environmental characteristics of high performance thermoplastics to friction materials.
Organic clutch friction facings are basicly composed of an organic matrix, fillers, solid lubricants and reinforcing fibers. An organic matrix has a structural function and has a large influence over the tribological properties of the system (coefficient of friction and wear rate in both, friction material as for the metal counterpart). Based on the automoti

5. Função de reação da política fiscal e intolerância da dívida: o caso brasileiro no período pós-real / Reaction Function of the Fiscal Policy and Debt Intolerance: The Brazilian Case in the Post-Real Period
Analyses of the sustainability of public debt across time in emerging countries are increasingly gaining in importance in the international economic debate, due to their importance for the evaluation of the macroeconomic policies of these countries. Following the June 1994 monetary reform that did away with hyperinflation, a major fiscal imbalance came to li

6. O inacreditável emprego de produtos químicos perigosos no passado
This work describes an overview of the use of chemicals in several commercial applications along the XXth century. The use of chemicals by men was largely empirical for many centuries, since there was no organized chemical and toxicological knowledge. During the XIXth century the chemical industry gained a crucial role in the development of technology, as ev

8. Acidentes com transporte rodoviario de produtos perigosos : analise e aplicação de modelo conceitual georreferenciado para avaliação de risco ambiental no minicipio de Campinas- SP / Highway transportation of hazardous materials accidents : characteristics and use of a conceptual model for analyzing environmental risk at Campinas, São Paulo State, Brazil
Highway accidents involving a vehicle transporting hazardous goods may cause extensive material, human and mainly environmental damage. Most of the areas crossed by highways are environmentally vulnerable due to the presence of creeks and rivers, different land use and possibility of the ground water being reached by the transported products. The county of C

9. Uma metodologia para avaliação de risco no transporte de produtos perigosos por rodovias
As of the statistical data from Fundação SEADE (Sistema Estadual de Análise de Dados Estatísticos), SEADE (2002) the goods transportation in Brazil and especially in the Estado of São Paulo constitutes a strategical segment of the economy. Thus, it is intensifying demanding more studies and research come back toward the efficiency questions, security an

10. Estudo da secagem de lodo de esgoto atraves da fritura de imersão
The increase in the population and in industrialization resulted in an increase in the volume of wastes. Part of these wastes is the wastewater and its treatment is a basic necessity of any society. Wastewater treatment generates large amounts of residues sewage sludge - that must be treated as well due to its dangerous nature and its large quantities. The o

11. Avaliação do risco de contaminação do lencol freatico, pelo herbicida tebuthiuron em cultura de cana-de-acucar, utilizando geoestatistica e simulador CMLS
Nowadays, sugar cane production demands application of several herbicides of which, tebuthiuron, has been largely used. In an area intensivelycropped with sugar cane and susceptible to leaching due to edaphic conditions, CMLS (ChemicalMovement in Layered Soils) model was used to evaluate ground water contamination risk with this herbicide. The main parameter

12. Estudo da contaminação por mercurio e metais pesados em garimpo de ouro primario : o estudo de caso da região de Pilar de Goias e Guarinos, Goias
The main concepts of mercury water chemistry and the environmental contamination by this metal as a by product of mining of primary gold at "Pilar de Goiás" and "Guarinos" regions, state of Goias. Brazil, are here discussed. The heavy metals of lithogenie origin (Cd, Zn, Cu, As, Pb) liberated into the water by the extraction and processing of gold are also
