1. Encoding of Luminescent Ink Markers Using Low-Level Data Fusion and Chemometrics
The identification and analysis of documentary fraud is always a challenge for forensic science. Document analysis has proven to be an important branch of forensics in elucidating the authenticity of documents. The development and incorporation of luminescent inks in authentic documents have proved to be an excellent security feature. This paper purposes the

2. Allometric models for estimating the leaf area of lisianthus (Eustoma grandiflorum) using a non-destructive method
ABSTRACT Lisianthus (Eustoma grandiflorum) is a cut flower grown due to the wide diversity of colors and longevity in the post-harvest. The leaf area measurement is fundamental in plants because the leaves are directly related to several processes such as transpiration, radiation interception and CO2 fixation that enable the plant to grow. The objective of t

3. Identification of Synthetic Drugs on Seized Blotter Papers Using ATR-FTIR and PLS-DA: Routine Application in a Forensic Laboratory
Blotter papers seizures containing synthetic drugs have intensified over the last decades. These drugs were originally conceived as “legal” alternatives to traditional illicit drugs, designed to mimic their effects and circumvent control agencies. Reference methods for determining these substances on blotter papers are based on chromatographic techniques

4. Double or triple-expressor lymphomas: prognostic impact of immunohistochemistry in patients with diffuse large B-cell lymphoma
Mid-Infrared absorption spectroscopy associate with the Partial Least Squares regression is the official method to monitor Brazilian commercial diesel quality. This method, however, uses solvents and a large number of samples for the construction of the calibration curves, which generates waste and increases the time needed for the analysis. In order to deve

6. Effect of Plasma Arc Welding on Residual Stress and Distortion of Thin Titanium Sheet
In this research work, a finite element model is developed to predict the temperature field and residual stress during plasma arc welding of thin Ti-6Al-4V sheets. Dhinakaran’s heat source model which is based on Parabolic Gaussian distribution is used to predict the temperature field and Anand’s model is used to predict the residual stress. Numerical si

7. Estimação da profundidade de fissuras em concreto através da velocidade de ondas ultrassônicas
RESUMO As fissuras são as manifestações patológicas mais recorrentes no concreto, devido as diferentes formas de exposição que o material está sujeito. Neste cenário, é importante que as edificações passem por inspeções através de diferentes métodos, dentre os quais os ensaios não destrutivos (END) aparecem como ferramenta alternativa. Dentre

8. Estimating Above-Ground Biomass of Araucaria angustifolia (Bertol.) Kuntze Using LiDAR Data
ABSTRACT The objective of this study was to test the performance of canopy data obtained from Airborne Laser Scanner (ALS) in generating estimates of above-ground biomass (AGB) of Araucaria angustifolia (Bertol.) Kuntze individuals. A cloud of ALS points located in a fragment of native urban forest in Curitiba, Paraná was used. The procedures consisted of:

9. Can leaf area in rice be defined by a mathematical model?
ABSTRACT The goal of this study was to define an empirical model to calculate the leaf area in rice from linear leaf measure in genotypes used by farmers in Brazil. Through the leaf dimensions it is possible to identify the final crop yield from the LAI. Therefore, the leaves shape is closely related to the production of photoassimilates that will be convert

10. Aerial biomass allometric models for Prosopis affinis Spreng. in native Espinal forests of Argentina
RESUMO A estimativa do carbono armazenado nos ecossistemas florestais requer ferramentas precisas para prever a biomassa. Objetivou-se nesse estudo determinar a biomassa aérea individual de Prosopis affinis e sua distribuição por componente; desenvolver modelos alométricos para prever a biomassa, e estimar os fatores de expansão da biomassa (FEB) em flo

11. Leaf area estimate of Pennisetum glaucum by linear dimensions
ABSTRACT. Leaf area measurements are of the main parameters used in agronomic studies to evaluate plant growth. The current study used a non-destructive method based on linear leaf dimensions (length and width) to select the regression model to estimate millet (Pennisetum glaucum) leaf area. For two millet genotype (IPA BULK 1 BF and ADR 300) 128 randomly-ch

12. A numerical analysis of a concrete slab breaching using high explosives
Resumo Invasão de perímetros com explosivos, demolições de estruturas robustas e incidentes envolvendo explosões não-programadas podem ser extremamente perigosos. A gravidade destes eventos demanda estudos que possam levar a um conhecimento mais profundo do fenômeno explosão e de sua interação com elementos estruturais. Este trabalho apresenta uma
