1. Are the dinosauromorph femora from the Upper Triassic of Hayden Quarry (New Mexico) three stages in a growth series of a single taxon?
ABSTRACT The lagerpetid Dromomeron romeri and the theropod Tawa hallae are two dinosauromorphs from the Norian (Upper Triassic) of the Chinle Formation, situated in New Mexico, USA. However, a recent study suggests the inclusion of the holotype of D. romeri (GR 218) and paratype (GR 155) and referred (GR 235) specimens of T. hallae in an ontogenetic series o

2. Ontogenia craniana comparada de Arctocephalus australis, Callorhinus ursinus e Otaria byronia (Otariidae: Pinnipedia)
The search for mechanisms that can generate major morphological changes has led to the study of ontogeny, in part because some kinds of modifications of ontogenies seem an excelent way to generate major phenotypic change. We focus here on Arctocephlaus australis, Callorhinus ursinus and Otaria byronia with the aim of contributing to the understanding of the

3. Human capital and economic growth: the case of the Parana state economics in the beginning of the century XXI / Capital humano e crescimento econÃmico: o caso da economia paranaense no inÃcio do sÃculo XXI
O objetivo desta pesquisa à analisar a influÃncia do capital humano na concentraÃÃo regional do crescimento econÃmico paranaense, no inÃcio do sÃculo XXI. Para tanto, optou-se pela metodologia de dados de painel, a partir da utilizaÃÃo do mÃtodo Least Squares Dummy Variables (LSDV), tendo como amostra os 399 municÃpios paranaenses, entre 1999 e 20

4. Formação, movimento e descompasso da rede urbana de Sergipe.
This thesis aims to study the urban network of Sergipe in order to know the movement of the network geographical space centrality due to the troubles caused by wealth production flows and social reproduction patterns that shaped the form, function and the network order. With a regional spatial approach using the triadic materialist dialectic method, the urba

5. PHYLOGENETICS AND MORPHOLOGICAL EVOLUTION OF SCLERACTINIAN CORALS
Scleractinian corals are modular organisms of great ecological and economic importance that may have solitary or colonial growth forms. In spite of the rich fossil record, the evolutionary history of the group is poorly understood and its taxonomy is highly artificial because many of the features commonly employed in systematic studies of the group exhibit l

6. PROFITABILITY IN PREPAID MOBILE PHONE SERVICES IN BRAZIL: OPPORTUNITIES WITH LOW INCOME CONSUMERS / RENTABILIDADE NA TELEFONIA MÓVEL PRÉ-PAGA NO BRASIL: OPORTUNIDADES COM CONSUMIDORES DE BAIXA RENDA
The strategy adopted by mobile phone operators in Brazil in recent years brought about great growth to these companies. However, it harmed their operation yield levels, and hence it is important that they seek new alternatives to rethink their trajectory of growth, fitting to an already established market. Historically, the relationship with prepaid customer

7. Depois do Estruturalismo, os Desafios Enfrentados pelo Desenvolvimento Brasileiro / Democracy and Self-sustained Growth
This work is divided in two major parts: firstly, there is a theorical study that emphasizes structuralism in Latin America, its crisis in the 80 s and a list of overlapping consensuses that deals with self-sustained economic development. The author draws, then, a development alternative. Secondly, the focus of this study is centered in Brazil. The main obst

8. The development and structure of the chimpanzee mandible.
The sites of growth and remodeling, and the associated changes in cortical bone structure, have been studied in the chimpanzee mandible and compared with those previously reported in the human and macaque mandibles. The location of the principal sites of growth, and the distribution of the areas of deposition and resorption in the ramus, were found to be sim

9. Responses of fibroblasts to anchorage of dorsal extracellular matrix receptors
Fibroblasts in 2D cultures differ dramatically in behavior from those in the 3D environment of a multicellular organism. However, the basis of this disparity is unknown. A key difference is the spatial arrangement of anchored extracellular matrix (ECM) receptors to the ventral surface in 2D cultures and throughout the entire surface in 3D cultures. Therefore

10. Very short-lived and stable mRNAs from resting human lymphocytes.
The kinetics of degradation of newly synthesized cytoplasmic poly(A)-bearing RNA have been examined in resting human lymphocytes. Two classes were identified, a very labile component with a half-life of less than 17 min and a stable component which remains apparently undiminished during 24 hr of observation. Both classes have molecular weights between 2.5 an

11. High frequency mitotic gene conversion in genetic hybrids of the oomycete Phytophthora sojae
Microbial populations depend on genetic variation to respond to novel environmental challenges. Plant pathogens are notorious for their ability to overcome pesticides and host resistance genes as a result of genetic changes. We report here that in particular hybrid strains of Phytophthora sojae, an oomycete pathogen of soybean, high frequency mitotic ge

12. Comparative bactericidal activity of ceftazidime against isolates of Pseudomonas aeruginosa as assessed in an in vitro pharmacodynamic model versus the traditional time-kill method.
Bactericidal activity, historically assessed by in vitro tests which employ fixed drug concentrations, may also be evaluated in in vitro pharmacodynamic models in which in vivo pharmacokinetics and bacterial growth conditions can be simulated. However, systematic comparisons between the two methods are lacking. We evaluated the bactericidal activities of cef
