13. Crescimento econÃmico secular no Brasil: uma investigaÃÃo empÃrica a partir da abordagem do crescimento com restriÃÃo externa
The main goal of this work is to study the Brazilian long run economic growth using the Keynesian approach of Balance-of-Payments Constrained Growth. Besides highlighting the importance of the terms of trade to the Brazilian economic growth in the periods 1900-2005 and 1900-1970, this work assess the importance of the capital flows to the Brazilian economic

14. The external restriction and the loss of dynamism of the brazilian economy: investigating the relations between productive structure and economic growth / A restrição externa e a perda de dinamismo da economia brasileira: investigando as relações entre estrutura produtiva e crescimento econômico
O objetivo central desta dissertação é analisar a perda de dinamismo do crescimento econômico brasileiro a partir da década de 80, utilizando a abordagem keynesiana de crescimento com restrição externa. De acordo com os resultados obtidos neste trabalho, pode-se dizer que o crescimento econômico brasileiro de 1930-2004 foi aquele compatível com o eq

15. Fragilidade financeira e restrição no balanço de pagamentos : b uma abordagem pos-keynesiana
Esta dissertação tem como principal objetivo desenvolver uma família de modelos formais em que sejam consideradas restrição no balanço de pagamentos e fragilidade financeira, sendo esta tomada no sentido minskyano. O trabalho está organizado em cinco capítulos, levando em conta a apresentação e as últimas observações. O segundo capítulo tem por

16. Finite element-based model for crack propagation in polycrystalline materials
In this paper, we use an extended form of the finite element method to study failure in polycrystalline microstructures. Quasi-static crack propagation is conducted using the extended finite element method (X-FEM) and microstructures are simulated using a kinetic Monte Carlo Potts algorithm. In the X-FEM, the framework of partition of unity is used to enrich

17. Length-weight relationship and condition factor of Micropogonias furnieri (Desmarest) (Perciformes, Sciaenidae) in the Sepetiba Bay, Rio de Janeiro State, Brazil
The length-weight relationship and spatial, temporal and ontogenetic changes in the condition factor of Micropogonias furnieri (Desmarest, 1823) were analyzed, from samples collected between October 1998 and September 1999, in the Sepetiba Bay, a coastal area with a wide communication with the sea (22º54'-23º04'S, 43º34'-44º10'W) at Southeast Brazil.

18. Limitation of Bacterial Growth by Dissolved Organic Matter and Iron in the Southern Ocean†
The importance of resource limitation in controlling bacterial growth in the high-nutrient, low-chlorophyll (HNLC) region of the Southern Ocean was experimentally determined during February and March 1998. Organic- and inorganic-nutrient enrichment experiments were performed between 42°S and 55°S along 141°E. Bacterial abundance, mean cell volume, and [3H

19. Heterotrophic Bacterial Growth Efficiency and Community Structure at Different Natural Organic Carbon Concentrations
Batch cultures of aquatic bacteria and dissolved organic matter were used to examine the impact of carbon source concentration on bacterial growth, biomass, growth efficiency, and community composition. An aged concentrate of dissolved organic matter from a humic lake was diluted with organic compound-free artificial lake water to obtain concentrations of di

20. Life history consequences of mammal sibling rivalry
Mammal life history traits relating to growth and reproduction are extremely diverse. Sibling rivalry may contribute to selection pressures influencing this diversity, because individuals that are relatively large at birth typically have an advantage in competition for milk. However, selection for increased growth rate is likely to be constrained by kin sele

21. Selective adsorption of l- and d-amino acids on calcite: Implications for biochemical homochirality
The emergence of biochemical homochirality was a key step in the origin of life, yet prebiotic mechanisms for chiral separation are not well constrained. Here we demonstrate a geochemically plausible scenario for chiral separation of amino acids by adsorption on mineral surfaces. Crystals of the common rock-forming mineral calcite (CaCO3), when immersed

22. Sustained Hedgehog signaling is required for basal cell carcinoma proliferation and survival: conditional skin tumorigenesis recapitulates the hair growth cycle
Temporally and spatially constrained Hedgehog (Hh) signaling regulates cyclic growth of hair follicle epithelium while constitutive Hh signaling drives the development of basal cell carcinomas (BCCs), the most common cancers in humans. Using mice engineered to conditionally express the Hh effector Gli2, we show that continued Hh signaling is required for gro

23. The Polynesian head: growth and form.
We consider the cranial base to be the primordial determinant of the head form and mandibular shape so common amongst (but not exclusive to) adult Polynesians. The flatness of the cranial base manifests its full influence only when growth of the upper facial skeleton is complete in early adulthood. We argue that during growth and maturation the upper facial

24. Colimitation of a freshwater herbivore by sterols and polyunsaturated fatty acids
Empirical data providing evidence for a colimitation of an herbivore by two or more essential nutrients are scarce, particularly in regard to biochemical resources. Here, a graphical model is presented, which describes the growth of an herbivore in a system with two potentially limiting resources. To verify this model, life-history experiments were conducted
