13. Métodos de ajuste da função Weibull e seu desempenho na prognose do crescimento e produção de Eucalyptus dunnii
The main objective of this research was to develop a simulator system of growth and yield for unthinned plantations of Eucalyptus dunnii using different adjustment methods for the Weibull probability density function to describe the forest structure at various ages. The data used in this research came from measurements of 239 plots in E. dunnii stands in the

14. Cefalostato virtual-posicionamento inicial para a padronização na marcação de pontos craniométricos em imagens obtidas por tomografia computadorizada, para uso em cefalometria / The Virtual Cephalostat - the preliminar adjustment for standardization of skull orientation in landmarks localization using CT in cephalometric analyses
Objective: The development of new technology in dental diagnosis by cone beam CT (CBCT) image, made possible and accessible the realization of cephalometric evaluation through volumetric reconstructions of the skull. Scientific parameters with evidence-based are needed to implement its use. Some parameters used in conventional cephalometry (2D) maybe need to

15. Caracterização espectroscópica e por modelagem mecânico-quântica, de compostos com potencial aplicação em dispositivos ópticos não-lineares
In the present work, the compounds 1-(3,4,5-trimethoxiphenil)-2-(2- tienyl) -5-(4-nitrophenylazo) pirrol (compound 1) and 5-dicianovinyl-5- piperidine-5,2:5:2- tertiophene (compound 2), were characterized using a combination of spectroscopic measurements and quantum mechanical calculation, aiming to evaluate if they present the necessary requisites for appli

16. Morphological asymmetry and broiler welfare
Health status, feed conversion ratio, and mortality are long known broiler chicken production indicators. However, further parameters are required by today's demanding meat markets, as these indicators are not sufficiently accurate to determine flock overall welfare. Morphological asymmetry has been pointed as an alternative welfare indicator as it reflects

17. Maturação dos frutos na emergência de plântulas e no potencial frutífero de pitangueira-do-cerrado (Eugenia calycina Cambess)
CAPÍTULO II: Eugenia calycina é uma espécie frutífera de ocorrência em áreas de Cerrado, cujas características morfofisiológicas de frutos e sementes são escassas. Diante disso, os objetivos do trabalho foram quantificar a influência da coloração do fruto nos caracteres morfofisiológicos de frutos e sementes da espécie; determinar o rendimento

18. Courtship behavior and sexual selection determined by size and symmetry in Dysdercus maurus Distant, 1901 (Hemiptera: Pirrhocoridae) / Comportamento de corte e cópula e papel do tamanho e simetria na seleção sexual de Dysdercus maurus Distant, 1901 (Hemiptera: Pirrhococoridae)
This study investigated the hole of size and corporal symmetry in the sexual selection of D. maurus, an insect-plague responsible for serious economic injuries in cotton cultures. Aspects of the courtship and mating behavior of this species were also described. In order to obtain the morphometric measurements, 30 single males and 30 couples were used for sli

19. ParÃmetros morfo-funcionais do olho e da organizaÃÃo retiniana no peixe de quartro-olhos Anableps anableps (Linnaeus, 1758)
The visual system represents an essential link between an animal and its surroundings with profound influence on its habits and life style in diverse types of habitats. In fishes of genus Anableps each eye contains two corneas, two pupillary apertures, an egg-shaped lens and one retina with distinct dorsal and ventral portions, which allow a simultaneous aer

20. Estudo da assimetria facial esqueletica e dimorfismo sexual em norma frontal, de individuos com oclusão dentaria classe I e classe II subdivisão de Angle
The aim of this study was to verify the incidence of skeletal asymmetry and sexual dimorphism of individuals with Angle s Class I occlusion within the normal limits, and individuals with Angle s Class II subdivision malocclusion. The sample consisted of seventy-one Caucasians aging 18 to 35 years (mean age=22.2) who volunteered for this study. Standardized p

21. Preparação de fases estacionarias para CLAE a partir de poli(metiloctilsiloxano) sobre a silica titanizada
This work investigated the process modification of a silica surface by titanium oxide followed by the sorption and immobilization of poly(methyloctylsiloxane) (PMOS) for use as stationary phase in high performance liquid chromatography, with special applications in alkaline mobile phases. The chromatographic support of titanized-silica was obtained by the ch

22. Estudo da relaxação magnetica e fluxo retido em Niobio supercondutor : efeitos da superficie
We present in this work a study of the surface influence in magnetic relaxation of superconducting niobium. We also discuss the relevance of the sample surface condition on magnetic flux trapping associated with the occurrence of a paramagnetic frozen state. Magnetization measurements were made, using a SQUID magnetometer, on a single-crystal Nb bar, for dif

23. Manual asymmetry and handedness.
Volumetric measurements show that right-handed individuals have larger right hands than left hands. In contrast, the hands of left-handers are much more nearly symmetrical. Based on what is known about trophic interactions between neurons and targets, these findings predict a corresponding asymmetry of the relevant parts of the sensorimotor system in right-h

24. What happens in the leucotomised brain? A postmortem morphological study of brains from schizophrenic patients.
Volume measurements were carried out on 19 brains from leucotomised schizophrenic patients and 20 age- and sex-matched controls using a stereological method. The volume of the total fixed brain, hemispheres, cortex, white matter, and central grey matter were all significantly reduced compared with controls. White matter and central grey structures were signi
