1. WOOD RESOURCE BALANCE FOR PLANTATION FORESTS IN BRAZIL: RESOURCES, CONSUMPTION AND CASCADING USE
ABSTRACT A resource balance comprises a method to monitor sources and uses of a given material. The wood resource balance analyses origins of wood resources used in the production of semi finished forest products. At the same time, the resource balance helps tracking wood processing residues and its further uses. A primary survey with 113 companies was condu

2. MORPHOLOGICAL AND GENETIC ANALYSIS OF Triplaris guayaquilensis Wedd (POLYGONACEAE): ONE NATIVE TREE OF ECUADOR
ABSTRACT In this paper, we assessed six native populations (55 trees) of Triplaris guayaquilensis Wedd (Fernan Sanchez), one of the major forest species from Ecuador, using morphological and AFLP (Amplified Fragment Length Polymorphisms) data. The populations were collected through two macro-sites (Central coastals: Quevedo, Ventanas, la Guayas; Andean surro

4. nfluence of the woodworkability parameters of Eucalyptus sp. wood in specific energy consumption for cutting in circular saw / InfluÃncia dos parÃmetros de usinagem da madeira de Eucalyptus sp. no consumo de energia especÃfica de corte em serra circular
New technologies used in the cutting of Eucalyptus sp. for the carbonization continuous process require care. The choice of tool and cutting speeds and feed influence on reducing the time and cost of energy during processing, optimizing its production. The objective was to verify the influence of the woodworkability parameters on specific energy spent cuttin

6. Morfologia, consequências do ataque de Lampetis nigerrima (Kerremans, 1897) (Coleoptera: Buprestidae) e poda de correção em clone de eucalipto / Morphology and damage of Lampetis nigerrima (Kerremans, 1897) (Coleoptera: Buprestidae), and pruning effect on cloned eucalypts
Two works were developed; the first objective was to find out important characters to be used in the identification of Lampetis nigerrima (Kerremans, 1897). Field activities were carried out in a commercial eucalypt plantation of cloned hybrid (Eucalyptus grandis vs E. urophylla), in the Grão Mogol County, Minas Gerais State, Brazil. Lab works were develope

7. Dermatomicoses em cães e gatos: avaliação do diagnóstico clínico-laboratorial e dos aspectos epidemiológicos em uma população de portadores de lesões alopécicas circulares. / Dermatomycoses in dogs and cats: evaluation of clinical, laboratory and epidemiological aspects in a population of patients with injuries alopecic circular.
As dermatomicoses são infecções fúngicas que afetam a pele e os folículos pilosos de cães e gatos, sendo causadas principalmente por dermatófitos dos gêneros Microsporum e Trichophyton e, menos comumente, por leveduras dos gêneros Malassezia e Candida. A dermatofitose é caracterizada clinicamente pela presença de lesões alopécicas circulares, en

8. Estudo de elementos estruturais roliços de madeira / Study of structural round timber
The aim of this work is the determination of stiffness and strength properties of structural round timber. Static bending and compression parallel to grain tests were carried out to obtain modulus of elasticity (MOE), shear modulus (G) and modulus of rupture (MOR). The results suggest that, in bending test, there is no influence in MOE determination due to s

9. Structural panel project for social housing making use of small diameter round-wood: product development / Painéis estruturais utilizando madeira roliça de pequeno diâmetro para habitação social: desenvolvimento do produto
The purpose of this work is to identify, from the analysis of the production chain of forest based products, the chances of making use of small diameter round-wood of the Eucalyptus and Pinus types, for the production of sealing structural panels destined for social housing. Wood as a renewable building material and, in accordance with the environmental a

10. Induction of Dimorphism in the Basidiomycete Lenzites saepiaria1
Sugars can serve as the germinant for basidiospores of the wood-rotting fungus Lenzites saepiaria. Hexoses sterilized by autoclaving were better germinants than hexoses that were sterilized by filtration. The degradation products in heated hexose which were responsible for the stimulation of germination were levulinic and formic acid. Another product of hexo

11. Jembrana Disease Virus Tat Can Regulate Human Immunodeficiency Virus (HIV) Long Terminal Repeat-Directed Gene Expression and Can Substitute for HIV Tat in Viral Replication
Jembrana disease virus (JDV) is a bovine lentivirus genetically similar to bovine immunodeficiency virus; it causes an acute and sometimes fatal disease in infected animals. This virus carries a very potent Tat that can strongly activate not only its own long terminal repeat (LTR) but also the human immunodeficiency virus (HIV) LTR. In contrast, HIV Tat cann
