13. Non-destructive measurement of leaf area and leaf pigments in feijoa trees
RESUMO A área foliar (cm2 por folha) e o conteúdo de pigmentos foliares são importantes características usadas para melhor entender a fisiologia das plantas. Neste estudo, modelos não-destrutivos para área foliar e conteúdo de pigmentos baseados no comprimento (L) e na largura (W) da folha, e na leitura do teor de clorofila, foram desenvolvidos para f

14. Eggshell Qualities as Indicative of Eggshell Strength for Layer Selection
ABSTRACT The study aimed at investigating which of four traits is the most representative of eggshell strength (destructive eggshell thickness measurement, eggshell weight, egg specific gravity, ultrasonic measurement of eggshell thickness) and could be used for selection purposes. To date, investigations focused mostly on pairwise (eggshell strength vs. ano

15. Non-resonant Permittivity Measurement Methods
Abstract The measurement of the dielectric properties of materials has been applied in non-destructive tests, humidity measurement, soil analysis and even cancer detection. The methods have been developed for over 70 years based on the interaction of the electromagnetic waves with the material under test. This work presents a general model of scattering para

16. Campomanesia velutina leaves extracts exert hypouricemic effects through inhibition of xanthine oxidase and ameliorate inflammatory response triggered by MSU crystals
ABSTRACT Gout is a destructive arthritis with a high prevalence worldwide. However, the available therapy is not able to increase life quality in many patients. Campomanesia velutina (Cambess) O. Berg, Myrtaceae, is used in Brazilian folk medicine to treat pain, inflammation and rheumatism. The aim of this study was to evaluate the potential of ethanolic and

17. Rutting analysis of 100 mm diameter polypropylene modified asphalt specimens using gyratory and Marshall compactors
Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a more realistic way of simulating actual compaction. In this study, mechanical differences of reference and polypropylene modified asphalt

18. Rutting prediction of asphalt mixtures modified by polypropylene fibers via repeated creep testing by utilising genetic programming
A novel application of genetic programming (GP) for modelling and presenting closed form solutions to the rutting prediction for polypropylene (PP) modified asphalt mixtures is investigated. Various PP fibers have been utilised for bitumen modification and repeated creep (RC) tests have been carried out. Marshall specimens, fabricated with multifilament 3 mm

19. O gigante dos pés de barro: capitalismo e desenvolvimento sustentável / THE FEET OF CLAY GIANT: Capitalism and Sustainable Development
This study resulted from many years of reflexion about big socio-environmental problems that gain more notoriety from 1960s decade and now, had occupied a central place in the academic debates and the society in general. The investigation has as central problem, to verify the contradictions, inconsistencies, conflicts and weaknesses all around the concept, a

20. Simulação da propagação de ondas ultrassônicas longitudinais em materiais estruturais aeroespaciais / Simulating the propagation of longitudinal ultrasonic waves in aerospace structural materials
The use of composite materials in the aerospace industry is increasing due to its low ratio between density and mechanical strength. To perform non-destructive testing using ultrasound, it is necessary to know the sound velocity in these materials. It is not always possible to manufacture physical prototypes during the development of a project because of tim

21. PROGRAMAÇÃO GENÉTICA, REDES NEURAIS ARTIFICIAIS E TÉCNICAS DE BALANCEAMENTO NA MODELAGEM DE DADOS AGRÍCOLAS: ESTUDO DA DOENÇA MOFO BRANCO
Data regression problems are common in the literature, therein it is desired to infer the relationship between the dependent (output) and independent variable (input) from a dataset. Infer the relationship between variables is not a simple task, many times there is a high non-linearity and noise in the data inside them. Two machine learning techniques that a

22. Modelo destrutivo com variável terminal em experimentos quimiopreventivos de tumores em animais
A indução química de substâncias cancerígenas em experimentos quimiopreventivos em animais é cada vez mais frequente em pesquisas biológicas. O objetivo destes experimentos biológicos é avaliar o efeito de um determinado tratamento na taxa de incidência de tumores em animais. Neste trabalho o número de tumores promovidos por animal será modelado

23. Distribuição COM-Poisson na análise de dados de experimentos de quimioprevenção do câncer em animais
Experimentos que envolvem a indução química de substâncias cancerígenas em animais são comuns na área biológica. O interesse destes experimentos é, em geral, avaliar o efeito de uma substância quimiopreventiva na destruição das células danificadas. Neste tipo de estudo, duas variáveis de interesse são o número de tumores induzidos e seus temp

24. Editorial
Inflammatory bowel diseases are characterized by a chronic clinical course of relapse and remission associated with self-destructive inflammation of the gastrointestinal tract. Active extracts from plants have emerged as natural potential candidates for its treatment. Abarema cochliacarpos (Gomes) Barneby & Grimes, Fabaceae (Barbatimão), is a native medicin
