1. Modeling residual biomass from mechanized wood harvesting with data measured by forest harvester
Abstract: The lack of accurate models for estimating residual biomass in wood harvesting operations results in underutilization of this co-product by forestry companies. Due to the lack of this information, forestry operations planning, such as chipping and transport logistics, are influenced, with a consequent increase in costs. Thereby, the aim of this stu

2. Modeling the individual height and volume of two integrated crop-livestock-forest systems of Eucalyptus spp. in the Brazilian Savannah
ABSTRACT. The aim of this study was to model the individual height and volume of eucalyptus wood in two integrated crop-livestock-forest systems (ICLF1 and ICLF2) in Campo Grande, a city in the state of Mato Grosso do Sul, Brazil. Classic nonlinear growth models were adjusted for height (Logistic, Gompertz, Richards, Weibull, Van Bertalanffy, Brody, Mitscher

3. Wood Volume Estimation in a Semidecidual Seasonal Forest Using MSI and SRTM Data
ABSTRACT The objective of this study was to evaluate the use of the MSI Sentinel-2 and SRTM data to estimate the volume of wood in a Semidecidual Seasonal Forest. Regression equations were fitted based on the remote sensing data, taking into consideration the individual bands and vegetation index of the MSI, elevation values and their derivatives obtained f

4. Remote Sensing and Geostatistics Applied to Post-stratification of Eucalyptus Stands
ABSTRACT Brazil has many rural properties with unmanaged eucalyptus stands. These plantations are heterogeneous, presenting different tree sizes, advanced ages, and large wood volumes that can be quantified using forest inventories. The prediction error of dendrometric variables, mainly in highly heterogeneous areas, can be associated with inadequate forest

5. Estudio hidrofóbico de soluciones acuosas diluidas de isómeros de pentanodiol a varias temperaturas a partir de datos volumétricos
Density of dilute aqueous solutions of 1,2 pentanediol, 2,4 pentanediol, 1,4 pentanediol and 1,5 pentanediol at 283.15, 288.15, 293.15, 298.15, 303.15 and 308.15 K in the concentration range 0.0000 to 0.0060 in mole fraction were determined by using Wood-Brusie type capillary neck pycnometers. The solute partial molar volume as a function of solute concentra

6. Nível de dano econômico para formigas-cortadeiras em função do índice de produtividade florestal de eucaliptais em uma região de Mata Atlântica
The production and quality of eucalyptus plantations have been studied in areas with different densities of ant nests, being important to estimate losses caused by leaf-cutting ants. The effects of leaf-cutting ant on wood production in differents productivity sites were studied in eucalyptus plantations in the region of Atlantic Forest, Minas Gerais State,

7. Tamanho de parcelas para quantificação de biomassa e carbono em uma floresta ombrófila densa na Mata Atlântica / Size of fragments for the quantification of biomass and carbon in a thick ombrophilous rainforest in Mata Atlântica
Rainforest is defined as a vegetable formation which takes up a large part of the Brazilian territory, from the Amazon Rainforest to the forests of the highlands of the southern states of Brazil, going through the Atlantic Forest. Due to the type of colonization Brazil had , which was a colonization of exploitation, a large part of this forest was destroyed,

8. Modelagem da dinâmica de crescimento de uma Floresta Ombrófila aerta do estado de Rondônia / Modelling of growth dynamics of tropical rain forest of State of Rondonia, Brazil.
A model of the growth dynamics of forests was developed applying Bertalanffy growth model (BGM) y=a[(1ebt)c] for individual trees. Based on linearized relationship with diameter and height equation LnH=b0+LnD and volume equation V=b0Db1Hb2 mutually compatible equations for diameter, basal area, height and volume were generated, adjusting parameters a and c o

9. USE OF REMOTE SENSING IMAGES TO ESTIMATE DENDROMETRIC CHARACTERISTICS OF EUCALYPTUS FORESTS / USO DE IMAGENS DE SENSORES REMOTOS NA ESTIMATIVA DE CARACTERÍSTICAS DENDROMÉTRICAS DE POVOAMENTOS DE EUCALIPTO
The Forest Management Information System is an integrated system which can be used to support the planning, implementation and monitoring of forest management activities. Beyond collected field information, geoprocessing and remote sensing systems are essential for that management type. One of the goals of this dissertation is to develop an analysis methodol

10. Estimativa do volume de madeira a partir do diâmetro da cepa em uma área explorada de floresta amazônica de terra firme
This research was carried within an area of tropical forest of terra-firme, in Breu Branco, Pará, in order to estimate the volume of trees, considering only the diameter of the trunks leftovers, which is necessary for the overseers to precisely estimate the volume of trees that were either illegally took away or were inappropriately cut off, even if respect

11. MODELOS DE CRESCIMENTO DE QUATRO ESPÉCIES MADEIREIRAS DE FLORESTA DE VÁRZEA DA AMAZÔNIA CENTRAL POR MEIO DE MÉTODOS DENDROCRONOLÓGICOS
Timber harvesting is an important economic activity in nutrient-rich floodplain forests (várzea) of Central Amazonia. In the Western Amazon basin of Brazil and Peru, access to terra firme forests is restricted due to the absence of a road network. Still, 6090% of the local and regional markets are provided with timber obtained from the floodplain forests. C

12. 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
