1. Investigation of modified platelet-rich plasma (mPRP) in promoting the proliferation and differentiation of dental pulp stem cells from deciduous teeth
Stem cells from human exfoliated deciduous teeth (SHEDs) have great potential to treat various dental-related diseases in regenerative medicine. They are usually maintained with 10% fetal bovine serum (FBS) in vitro. Modified platelet-rich plasma (mPRP) would be a safe alternative to 10% FBS during SHEDs culture. Therefore, our study aimed to compare the pro

2. ON AUTOMATIC DIFFERENTIATION AND ALGORITHMIC LINEARIZATION
We review the methods and applications of automatic differentiation, a research and development activity, which has evolved in various computational fields since the mid 1950's. Starting from very simple basic principles that are familiar from school, one arrives at various theoretical and practical challenges. The resulting activity encompasses mathematical

3. Diferenciação automática de matrizes Hessianas / Automatic differentiation of hessian matrices
In the context of nonlinear programming, many algorithms boil down to the application of Newton s method to the system constituted by the first order Lagrangian conditions. The calculation of Hessian matrices is necessary in this class of solvers. Our focus is on the exact calculation, within machine precision, of Hessian matrices through automatic different

4. Otimização de forma de cascas axissimétricas utilizando diferenciação automática / Shape optimization of axisymmetric shells using automatic differentiation
Cascas constituem um tipo de estrutura que possui uma vasta quantidade de aplicações, incluindo, por exemplo, fuselagens de aviões e submarinos, silos metálicos, coberturas de hangares, estruturas de prédios e componentes automotivos e aeroespaciais. Os grandes vãos possíveis de serem cobertos, baixo peso e alta rigidez são algumas das vantagens obti

5. Estudos dos genes Tbx19 e Crhr1 em cães da raça poodle com hipercortisolismo ACTH-dependente / Study of Tbx19 and Crhr1 genes in Poodle dogs with ACTH-dependent hypercortisolism
The ACTH-dependent hypercortisolism (ADH), also called Cushings disease, is one of the most commonly diagnosed endocrine diseases in dogs. The symptoms occur due to glucocorticoids excess leading to gluconeogenic, catabolic, anti-inflammatory and immunosuppressive effects in multiple organs and systems. There is a high incidence of Cushings disease in Poodle

6. Simulador de meios porosos saturados elastoplasticos / Numerical simulator of saturated elastoplastic porous media
The exploration of mineral resources is growing in importance in the Brazilian economy. Since the environments in which these resources are found are becoming increasingly more complex and challenging for the production phase, currently unavailable knowledge and technologies are required to produce these reserves. In the particular well drilling and completi

8. Soils and environments of the Ferriferous Quadrangle (MG) and forestry suitability of the Coastal Plains / Solos e ambientes do QuadrilÃtero FerrÃfero (MG) e aptidÃo silvicultural dos Tabuleiros Costeiros
Two quite different Brazilian environments were approached in this work: the Ferriferous Quadrangle, located in the center-south portion of the State of Minas Gerais, and Coastal Plains, which extend in narrow strip along the coast from the State of Rio de Janeiro to AmapÃ. The first was studied in a more general context, with respect to the distribution of

9. Characterization of gene expresiion of tumoral cells in patients with sporadic colon adenocarcinoma / Caracterização da expressão genica de celulas tumorais de pacientes com adenocarcinoma esporadico do colon
The molecular mechanisms involved in sporadic colon adenocarcinoma (SCA) are still not completely elucidated. Recently, the serial analysis of gene expression (SAGE) method has allowed the global analysis of genes expressed in diverse cellular types but there are no studies in purified epithelial cells of SCA moderately differenciated. We have characterized

10. Desenvolvimento de metodo implicito para simulador numerico tridimensional de escoamentos compressiveis inviscidos
The simulation of compressible flows considered inviscid is largely appliable to aeronautics. The development of such simulations using the Garlekin discontinuous method[7,12,16,20], wich presents the good characteristics of fine element and finite volume methods, benefitting from the polynomial interpolation within subdomains and discontinuous across interf

11. Integração digital de imagens de radar e LANDSAT-TM com dados geológicos e aerogamaespectrométricos no auxílio ao mapeamento geológico da região do Complexo Granítico Estrela - Pará (PA) / Radar, geologic, airborne gamma ray and LANDSAT-TM digital data integration for geological mapping of the Estrela Granite Complex (PA).
This work is focused on the geotectonic context of the Carajás Mineral Province, Amazon Craton, which represents the most important Brazilian Mineral Province and hosts iron, cooper, gold, manganese and nickel deposits. At the end of Archean age, during the tecno-metamorphic evolution, moderated alkaline granitoids were generated, such as, Estrela Granite C
