15. Potential of Texture Analysis for Charcoal Classification
Abstract Charcoal produced from reforested wood can be distinguished from the charcoal derived from the wood of native species. This identification is very important for the trade, control and monitoring of charcoal production in Brazil. This study investigated the potential of texture analysis for classifying the charcoal based on origin (eucalyptus or nati

17. Diferenciação de miofibroblastos em feridas após uso tópico do metronidazol: estudo experimental.
RESUMO Objetivo: avaliar os efeitos da administração tópica do metronidazol na diferenciação de fibroblastos e na contração da ferida durante cicatrização experimental por segunda intenção em ratos. Métodos: cento e oito animais foram submetidos a uma ferida circular no dorso, com 2cm de diâmetro e divididos em seis grupos: grupo controle, com

18. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

20. Digital Approach for Measuring Tree Diameters in the Amazon Forest
ABSTRACT Buttresses and other natural structures modify the shape of stems in Amazonia and change the diameter at breast height (DBH) measured at 1.3 m at ground level. The lack of adequate measurement techniques affects negatively forest dynamics analyses and biomass estimating. The study evaluated an indirect method of measuring diameters in trees with DB

21. Digital Soil Mapping of Soil Properties in the “Mar de Morros” Environment Using Spectral Data
ABSTRACT Quantification of soil properties is essential for better understanding of the environment and better soil management. The conventional techniques of laboratory analysis are sometimes costly and detrimental to the environment. Thus, development of new techniques for soil analysis that do not generate residues, such as spectroscopy, is increasingly n

22. Digital Soil Mapping Using Machine Learning Algorithms in a Tropical Mountainous Area
ABSTRACT: Increasingly, applications of machine learning techniques for digital soil mapping (DSM) are being used for different soil mapping purposes. Considering the variety of models available, it is important to know their performance in relation to soil data and environmental variables involved in soil mapping. This paper investigated the performance of

23. Metodología ad hoc para la observación de superficies de desgaste y fractura
ABSTRACT In the present work, a methodology of microscopic analysis and measurement of wear surfaces is presented, based on images made using digital processing techniques such as stitching and stac-king. The images are obtained from an ad-hoc and low-cost microscopic observation system, consisting of sample positioning and focus-elevation modules with micro

24. Métodos temporales para determinar deformaciones límite en chapas metálicas
ABSTRACT The forming limit diagram (FLD) –broadly used to characterize sheet-metal formability– is made by means of strain measurement over the surface of stretched samples and the subsequent determination of limit-strain values associated with the onset of necking. Currently, researchers can make strain measurements with digital image-correlation analys
