1. A COMBINATION OF DISCRETE EVENT SIMULATION AND MULTI-CRITERIA ANALYSIS TO CONFIGURE SUGARCANE DROP AND HOOK DELIVERY SYSTEMS
ABSTRACT This article explores decision analysis regarding Drop and Hook (D&H) transportation operations at sugarcane mills. By means of a case study, a combination of a discrete event simulation model and multi-attribute utility theory was used to evaluate different configurations for sugarcane delivery systems using internal, external, or no D&H systems. A

2. Fighting Collinearity in QSPR Equations for Solution Kinetics with the Monte Carlo Method and Total Weighting
A Monte Carlo method is used in addition to functional and individual weighting to overcome multicollinearity problems in multiple linear regression equations applied as quantitative-structure-property-relationships, allowing the estimation of correct coefficient confidence intervals. The method was applied to rate constants for the Menschutkin reaction betw

3. Jenynsia luxata, a new species from Northwestern Argentina, with additional observations of J. maculataRegan and phylogeny of the genus (Cyprinodontiformes: Anablepidae)
Jenynsia luxata, a new species from northwestern Argentina, is described. This species is diagnosable from all other Jenynsia by the medial processes of left and right pelvic bones relatively reduced and separated from each other. The new species resembles J. multidentata, but it is further distinguished from this species by the absence of a swelling between

5. Inferência filogenética em gaviões buteoninos (Aves: Accipitridae), com base em caracteres osteológicos cranianos / Phylogenetic inference in buteonine hawks (Aves: Accipitridade), based on cranial osteological characteres
The buteonine hawks are members of the family Accipitridae with a worldwide distribution but mainly restricted to the Neotropics. Traditionally, the buteonine group has included the genera Buteo, Busarellus, Buteogallus, Geranoaetus, Geranospiza, Harpyhaliaetus, Leucopternis and Parabuteo. Recently, molecular data has indicated that two other genera, Ictinia

6. Vibration H-infinity control with constrained force signal / Controle H-infinito de vibrações com restrições no esforço de controle
In this work, the H8 control of vibrations problem taking into account the effects of saturation of actuators is studied. Two situations of interest were explored. The first one considers that saturation should be avoided and does not cause damage to the system, even if this situation leads to loss of performance. The second alternative seeks to modify the c

7. Sistema colinérgico central modula os ajustes dos sistemas cardiovascular e termorregulatório induzidos pelo exercício físico até a fadiga
ABSTRACT The purpose of this study was to verify if the cardiovascular and thermoregulatory adjustments mediated by central cholinergic receptors and peripheral cathecolamines during the physical exercise until fatigue. Wistar rats weighting 278 ± 5 g, were submitted to bilateral adrenodemedullation (ADM) or sham (SHAM) surgery. After recovery, the animals

9. A contribution to the study about multicriterion optimization methods / Uma contribuição ao estudo dos métodos de otimização multi-objetivo
In optimization problems, there are many situations in which the users goal is to minimize and or maximize several functions simultaneously, instead of dealing with a single objective function. These functions form a mathematical description of performance criteria, which are usually in conflict with each other. This situation is formulated as a multicriteri

10. Pressão arterial e manipulação tubular renal de sodio em um modelo de septicemia em ratos
Acute renal failure is a frequent complication in septic patients associated with a high mortality rate. An important characteristic is a decrease in glomerular filtration rate, which is even present in situations where renal blood flow has been maintained. Prevailing hypothesis on the pathogenesis of renal failure suggest an inappropriate and uncontrolled r

11. Dynamic weighting in Monte Carlo and optimization
Dynamic importance weighting is proposed as a Monte Carlo method that has the capability to sample relevant parts of the configuration space even in the presence of many steep energy minima. The method relies on an additional dynamic variable (the importance weight) to help the system overcome steep barriers. A non-Metropolis theory is developed for the cons

12. Three-dimensional functional magnetic resonance imaging of human brain on a clinical 1.5-T scanner.
Functional magnetic resonance imaging (fMRI) is a tool for mapping brain function that utilizes neuronal activity-induced changes in blood oxygenation. An efficient three-dimensional fMRI method is presented for imaging brain activity on conventional, widely available, 1.5-T scanners, without additional hardware. This approach uses large magnetic susceptibil
