1. FITTING AND CALIBRATING A MIXED-EFFECTS SEGMENTED TAPER MODEL FOR BRUTIAN PINE
ABSTRACT Taper models are one of several necessary tools in modern forest inventory, giving information on diameter at any point along the tree stem and this information can also be used to estimate stem volume. In this study, we used nonlinear mixed-effects (NLME) modeling approach to minimize existing statistical problems in constructing taper equations. A

2. Modeling of stem form and volume through machine learning
Abstract Taper functions and volume equations are essential for estimation of the individual volume, which have consolidated theory. On the other hand, mathematical innovation is dynamic, and may improve the forestry modeling. The objective was analyzing the accuracy of machine learning (ML) techniques in relation to a volumetric model and a taper function f

3. Buckling and Vibration of Functionally Graded Non-uniform Circular Plates Resting on Winkler Foundation
Abstract An investigation on the effect of uniform tensile in-plane force on the radially symmetric vibratory characteristics of functionally graded circular plates of linearly varying thickness along radial direction and resting on a Winkler foundation has been carried out on the basis of classical plate theory. The non-homogeneous mechanical properties of

4. Effects of intensified training and taper on immune function
Quando se compara a função imune, em repouso, de atletas e não atletas, não se verificam grandes diferenças. Porém, períodos de treinamento intensificado ("overreaching") em atletas bem treinados podem induzir supressão da imunidade no estado de repouso. Os atletas com maior propensão para contrair doenças parecem apresentar uma resposta alterada d

5. A problemática da fixação do valor da reparação por dano moral: um estudo sobre os requisitos adotados pela doutrina e jurisprudência tendo em vista a natureza e função pedagógico-punitiva do instituto
This piece of work has the intent of making a critical rereading of the requisites adopted by the major part of the doctrine and jurisprudence on fixation of the value for reparation when it comes to punitive damages. An analysis of those requisites was made with the purpose of showing that some of them are obsolete due to the arrival ofthe Federal Constitut

6. Avaliação de uma metodologia para otimização de volume de toras comerciais de Eucalyptus sp. em função da qualidade do fuste / Evaluation of a methodology for volume optimization of Eucalyptus sp. merchantable logs as a function of stem quality
This work had as general objective the evaluation of a methodology for estimate of the wood volume in the forest inventory, considering the profile of quality of the stem of the trees. A stand was used with area of 4,31 ha planted with Eucalyptus sp. with 16 year-old, originated from seminific propagation. The initial spacing used in the planting was 3 x 3 m

7. Growth, Production and Economic Analysis of Clonal Stands of Eucalyptus sp. in Agroforest Systems. / Crescimento,produÃÃo e anÃlise econÃmico de povoamentos Clonais de Eucalyptus sp, em sistemas agroflorestal.
The aims of the present study were to adjust models of productivity for a sawmill to test taper functions using segmented and non segmented polynomial models to estimate the profile of the treesâ trunk to prognosticate the present and future production of stands of eucalypt and to analyse the economic viability of a âagrossilvopastorilâ system with eucaly

8. A STUDY OF THE RADIO LINK ATTENUATION USING DOUBLE-PASSIVE REPEATERS / ESTUDO DA ATENUAÇÃO NOS ENLACES RADIOÉLETRICOS QUE EMPREGAM SISTEMAS REPETIDORES DUPLO PASSIVOS
This theoretical study gives the propagation loss through a microwave radio relay system using doublé-passive configuration in the Fresnel zone of the exciting parabolic antenna. Two cases are treated separately: a) Plane passive repeaters with equal rectangular apertures. b) Plane passive repeaters with nonequal square apertures. Based on the results obtai

9. Pentameric assembly of a neuronal glutamate transporter
Freeze-fracture electron microscopy was used to study the structure of a human neuronal glutamate transporter (EAAT3). EAAT3 was expressed in Xenopus laevis oocytes, and its function was correlated with the total number of transporters in the plasma membrane of the same cells. Function was assayed as the maximum charge moved in response to a series of transm
