1. Analysis of the chloride diffusion coefficients by different test methods in concrete mixtures containing metakaolin and high-slag blast-furnace cement
ABSTRACT This study aims to evaluate the chloride diffusion coefficient and the service life (SL) of concretes containing metakaolin and high-slag blast-furnace cement (HSBFC). Accelerated methods of chloride ion diffusion and migration (RCPT, RMT, BDT and multiregime test method) were used. To produce the specimens, HSBFC resistant to sulphates (CPIII 40 RS

3. Development of an organic quinoa bar with amaranth and chia
Abstract Quinoa is an Andean crop with extraordinary nutritional properties. Its high protein content and well-balanced amino acid composition make it a unique food product for health-conscious consumers. The aim of this study was to develop a cereal bar using organic quinoa with amaranth, chia seeds, nuts and dried fruits. Seven bar prototypes were designe

4. Comportamiento bi-modal de una fundición gris y un acero estructural al carbono en corrosión atmosférica marina acelerada
ABSTRACT According to data gathered in the last Metal Foundry Industrial Production Survey [1], approximately 46% of the industrial production of ferrous alloys is gray-iron. In this context the study of the atmospheric corrosion resistance of gray-iron becomes interesting to asset its useful life when subject to weathering conditions. The studies of gray-ir

7. Alterations of morphology, mechanical and osteogenic capacity of mdx mice bones / Alterações da morfologia, resistência mecânica e capacidade osteogênica dos ossos de camundongos mdx
Duchenne muscular dystrophy (DMD) is a neuromuscular disease caused by lack of dystrophin. DMD patients have brittle bones because of muscle weakness and use of glucocorticoids. The mdx mouse is widely used as experimental model for the study of DMD and it presents lack of dystrophin, intense inflammatory process and muscle fiber degeneration. Moreover, it p

8. Contribution to the development of performance specifications for concretes containing blast furnace slag / Contribuição ao desenvolvimento de especificações por desempenho para concretos com escoria de alto-forno
In 2008 alone, the annual steel production in Brazil was around 31 million tons. The steel production process generates an average of 500 kg of residues and co-products per ton of steel. From this total, 70% corresponds to the slags. Although investigating the increase of blast furnace slag use is of extreme importance for the concrete and steel industries s

9. Anthropometry determinants to asthma and atopy in Children: cohort scaala, Salvador-Ba. / Determinantes antropométricos da asma e atopia em crianças: coorte scaala, Salvador-Ba.
This study is about weight gain in children until two years of age and their nutritional conditions as to early exposures related to asthma and atopy. Children under three years of age, living in Salvador-BA, were studied, prospectively, from 1997 to 2007. Initially, in the present thesis, the association between weight gain in the first two years of life an

12. Method to reduce soiling deposition on building envelope. / Método para redução de mancha nas vedações externas de edifícios.
Building roofs and façades usually show blackening surfaces after few years in large cities. On porous and silicious materials those soiling is caused by particles pollution depositions and mould growth, and the available methods available to prevent this phenomenum do not have a good performance along its service life. This thesis, based on an intensive la
