1. ROTAXANOS - INTERAÇÕES INTERCOMPONENTES E MOVIMENTOS MOLECULARES
Rotaxanes are currently one of the most promising objects of study in the field of artificial molecular machines. A rotaxane molecule is composed by two or more molecular components that are connected by a mechanical bond. 51 years ago, the first synthesis of this type of molecules was performed, since then, there has been a great effort in obtaining new mod

3. EL DUALISMO CARTESIANO Y SU RELACIÓN CON LA NUEVA MEDICINA A LA LUZ DE SU CORRESPONDENCIA
ABSTRACT Despite of the fact that R. Descartes’s reduction of animals to mere machines can be explained as a logical consequence of his metaphysical and gnoseological starting point, one can argue that this reduction seems to be very difficult to defend, since it appears to be contradictory to our everyday experience. On the other hand, one of the explicit

4. Soil Compaction Due to Wood Harvesting Traffic at Different Extraction Distances
ABSTRACT This study evaluated the effect on Oxisol soil compaction of traffic by wood harvesting machines from different extraction distances carried out by a logging company located in Paraná State. The harvesting system was composed of a feller buncher, skidder and harvester, in which soil compaction was evaluated at four extraction distances and four dep

5. Fuzzy control applied to an electrical power generation system mounted on tractors for driving of agricultural implements
ABSTRACT The demand of the agricultural sector for more operationally efficient machines and implements motivated the development of alternatives for driving of this equipment. Aiming an electrical supply to apply in agricultural implements, this study proposes a system that uses the tractor power take off to activate a synchronous generator, using a fuzzy l

6. Broadcast distribution uniformity of fertilizer with centrifugal spreaders used in variable rate application
ABSTRACT The quality of fertilizer distribution process is important to the success of agriculture. This research aimed to study the distribution uniformity of fertilizers with spreaders capable of performing variable rate. Evaluations were carried out in different farms, in the Southwest region of the State of Goiás, Brazil. 13 longitudinal and transversal

7. Impact of Electronic Voting Machines on Blank Votes and Null Votes in Brazilian Elections in 1998
Electronic voting machines were used for the first time in general elections in Brazil in 1998; in that year, some cities used this new voting method, while others continued to vote using paper ballots. Few studies have demonstrated that the rate of invalid votes for federal deputy was significantly lower in cities that used electronic voting machines. This

8. Natural rubber latex: determination and interpretation of flow curves
AbstractAs consumers become more demanding, the importance grows of guaranteeing the quality of products. The employment of reliable testing techniques that assure the origin and characteristics of the inputs used by industry is a key factor in this respect. In the rubber processing industry, the most commonly used characterization tests include determinatio

9. Multiple Dynamics of Hydrazone Based Compounds
Hydrazone derivatives of 2-quinolinecarboxaldehyde and 6-bromo-2-pyridinecarboxaldehyde were synthesized by sequence reactions with hydrazine derivatives. These compounds exhibited E/Z isomerization upon irradiation using a mercury lamp (250 W). The configurational changes were monitored by 1H nuclear magnetic resonance (NMR), UV-Vis and fluorescence spectro
