13. Validation of a physical anthropology methodology using mandibles for gender estimation in a Brazilian population
Validation studies of physical anthropology methods in the different population groups are extremely important, especially in cases in which the population variations may cause problems in the identification of a native individual by the application of norms developed for different communities. OBJECTIVE: This study aimed to estimate the gender of skeletons

14. Diterpenes from marine brown alga Dictyota guineensis (Dictyotaceae, Phaeophyceae)
The crude extract of the marine brown alga Dictyota guineensis was analyzed by high-resolution gas chromatography-mass spectrometry (HRGC-MS). Five diterpenes were identified: dictyol E (the most abundant diterpene), dictyotadiol, dictyoxide, isopachydictyol A and pachydictyol A, all diterpenes from the chemical group I, i.e., mainly prenylated derivatives o

15. Corais como organismos biomonitores: aplicação, pré-tratamento e determinação de elementos majoritários e minoritários
Corals incorporate major and trace elements in their tissues and skeletons, acting as good proxies for contaminant inputs over time. This incorporation occurs by a variety of mechanisms and depends on the bioavailability of elements. Corals are very susceptible to metal contamination during sample collection. As such, pre-treatment procedures need to include

16. What are and where are the bioactive terpenoids metabolites from Dictyotaceae (Phaeophyceae)
Dictyotaceae are a rich source of secondary metabolites, especially terpenes. These natural products have been studied for their bioactivity for human and for their ecological role in nature. The present work highlights de diversity of the Dictyotaceae terpenes, emphasizing their bioactivities and the biogeography of their sources. The sesquiterpenes are fou

17. ANATOMIA COMPARADA DO ESQUELETO ENDOFRAGMAL NA FAMÍLIA DE CARANGUEJOS DE ÁGUA DOCE TRICHODACTYLIDAE (CRUSTACEA: BRACHYURA)
In brachyuran crustaceans the endophragmal skeleton is the main support structure of the locomotory complex. Its origin is cuticular and it is formed by the sternite and pleurite plates of the eight thoracic somites and their internal invaginations. The ventral characters of the endophragmal skeleton, reflected externally in the suture lines of the thoracic

18. Inferência filogenética em gaviões buteoninos (Aves: Accipitridae), com base em caracteres osteológicos cranianos / Phylogenetic inference in buteonine hawks (Aves: Accipitridade), based on cranial osteological characteres
The buteonine hawks are members of the family Accipitridae with a worldwide distribution but mainly restricted to the Neotropics. Traditionally, the buteonine group has included the genera Buteo, Busarellus, Buteogallus, Geranoaetus, Geranospiza, Harpyhaliaetus, Leucopternis and Parabuteo. Recently, molecular data has indicated that two other genera, Ictinia

20. Antitumoral activity, isolation and identification of compounds actives of kielmeyera coriacea Mart &Zucc / Atividade antitumoral, isolamento e identificação dos principios ativos da Kielmeyera coriacea Mart &Zucc
Kielmeyera coriacea Mart. (Clusiacea), popularly known as Pau-Santo (Alves et aI., 2000), was one of the Cerrado species that showed significant antiproliferative activity in previous tests and therefore was selected for this study. Activity guided fractionation of the crude dichloromethane extract was undertaken to isolate and identify the active compounds

21. Ocorrência e atividade biológica de quassinóides da última década
Quassinoids, the bitter principles of the Simaroubaceae family, are a group of structurally complex and highly oxygenated degraded triterpenes. They are divided into five groups according to their basic skeleton, C-18, C-19, C-20, C-22 and C-25. In recent years, attention has been focused on quassinoids because several of them have shown promising biological

22. Uso de saliências do contorno via esqueletização para recuperação de imagens
A recuperação de imagens é um ramo oriundo da recuperação de informação que vem recebendo grande enfoque atualmente. E dentro deste novo ramo a recuperação baseada em formas é uma das tarefas mais difíceis. Assim, esse trabalho explora os principais aspectos de recuperação baseada em forma: a representação e a descrição de formas, que visam

23. Studies toward the synthesis of jungianol and construction of benzofurans by TTN-mediated ring contraction / Estudos visando à síntese do jungianol e a construção de anéis benzofurânicos utilizando TTN
This thesis describes the studies aiming at the synthesis of jungianol and the construction of benzofuranic rings. In both cases, the key-step is the reaction of thallium(III)-mediated ring contraction. Jungianol is a phenolic sesquiterpene isolated by Bohlmann et al., in 1977, from the species Jungia malvaefolia. The key-step of the synthesis could be the r

24. Height estimation trough limb s long and dry bones and pelvis bones measurements / Determinação da estatura por meio da medida de ossos longos e secos dos membros inferiores e dos ossos da pelve
There are no Brazilian patterns for height estimation through limbs. long and dry bones measurements. The only national paper studied the length of fresh bones, correlating them with body height. Since the Brazilian racial miscegenation is completely "sui generis", a study was proposed on human height in order to establish a pattern for long and dry bones of
