13. Variabilidade química dos óleos essenciais e do teor de fenóis em folhas e frutos da jabuticabeira (Myrciaria cauliflora) / Chemical variability of essential oils and phenol content in leaves and fruits of jabuticabeira (Myrciaria cauliflora)
Foliar contents of total phenols and tannins and the essential oil composition of Myrciaria cauliflora populations cultivated in six sampling sites have shown the presence of four clusters related to soil types and foliar nutrients. Cluster I included samples which originated from sandy soil (S1) with the highest and lowest percentages of γ-eudesmol (11

15. Medindo valores com parcelas de itens: contribuições à teoria funcionalista dos valores / MEASURING VALUES WITH ITEM PARCELS: CONTRIBUTIONS TO FUNCTIONAL THEORY OF VALUES
ABSTRACT - The current thesis aimed to create a new instrument for measurement of human values, based on the functionalist theory of human values, for diagnosis and screening. To this end, it took out three studies. Study 1 aimed to build up a database of items that would meet an essential criterion: to represent the subfunctions recommended by the functiona

16. Brand personality dimensions in the Brazilian context
Brands may be perceived as possessing a set of distinct traits or characteristics, i.e., a personality, similar to a person. Thus, the personality of a brand is relevant as a source of differentiation in an increasingly competitive market environment. In this study, the authors explore the dimensions of brand personality proposed by J. Aaker (1997), seeking

18. Gene trio signatures as molecular markers to predict response to doxorubicin cyclophosphamide neoadjuvant chemotherapy in breast cancerpatients
In breast cancer patients submitted to neoadjuvant chemotherapy (4 cycles of doxorubicin and cyclophosphamide, AC), expression of groups of three genes (gene trio signatures) could distinguish responsive from non-responsive tumors, as demonstrated by cDNA microarray profiling in a previous study by our group. In the current study, we determined if the expres

19. Differential gene expression profiles of hepatocellular carcinomas associated or not with viral infection
Chronic hepatitis B (HBV) and C (HCV) virus infections are the most important factors associated with hepatocellular carcinoma (HCC), but tumor prognosis remains poor due to the lack of diagnostic biomarkers. In order to identify novel diagnostic markers and therapeutic targets, the gene expression profile associated with viral and non-viral HCC was assessed

21. ESTUDO TEÓRICO DA RELAÇÃO ESTRUTURAATIVIDADE DE DERIVADOS ANÁLOGOS DA CAFEÍNA CONTRA O CÂNCER EPITELIAL
Some caffeine analogues present activity against skin cancer. In this work, chemometric methods were applied in the search for building discriminant models between active and inactive analogues, based on the correlations among their biological activities and electronic and geometric molecular descriptors. From 70 descriptors calculated with density functiona

22. Combinação de múltiplos classificadores para reconhecimento de face humana
Lately, the human face object has been exploited by the advent of systems involving biometrics, especially for applications in security. One of the most challenging applications is the problem of human face recognition, which consists of determining the correspondence between an input face and an individual from a database of known persons. The process of fa

23. Classicação de Regiões de Mamografias em Massa e Não Massa usando Estatistica Espacial e Máquina de Vetores de Suporte / Classification of Regions, in the Mamogra Mass and not using statistical Mass Space and Support Vector Machine
Breast cancer is a serious public health problem in several countries of the world. Computer-Aided Detection/Diagnosis systems (CAD/CADx) have been used with relative success in aid to health care professionals. The main contribution of this work is to present a methodology to discriminate and classify mammogram regions in mass and non-mass through spatial s
