1. Role of apparent diffusion coefficient measurement in differentiating histological subtypes of brain metastasis of lung cancer
SUMMARY OBJECTIVE: The aim of this study was to investigate the role of apparent diffusion coefficient of diffusion-weighted imaging in differentiating histological subtypes of brain metastasis of lung cancer. METHODS: Diffusion-weighted imaging of 158 patients (mean age: 61.2±10.68 years) with brain metastasis of lung cancer (36 small cell lung cancer an

2. Rutting analysis of 100 mm diameter polypropylene modified asphalt specimens using gyratory and Marshall compactors
Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a more realistic way of simulating actual compaction. In this study, mechanical differences of reference and polypropylene modified asphalt

3. Método de dosagem de concreto pelo volume de pasta com emprego de cinza volante / Concrete mix-proportioning method by cement paste volume using fly ash
This study was developed in order to create and a streamlined methodology of concrete mix proportioning using fly ash to reduce the cement content and an intensive use of a pollutant contributing to the increase of sustainability in construction through reducing consumption of clínquer and the release of carbono dioxide to the atmosphere. It was established

4. Thermal analysis evaluation of the reactivity of coal mixtures for injection in the blast furnace
Pulverized Coal Injection (PCI) is an important standard technology replacing coke partially by pulverized coal into the blast furnace that allows a significant reduction of hot metal costs and environmental impact, contributing to a decrease of coke requirements for ironmaking. Coals typically used in this process in Brazil are, at current time, exclusively

5. 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

7. Estudo de dosagem de concreto convencional feito como CP II F-32 e agregados de Rio Branco-Acre e utilização de uma argila calcinada como pozolana na substituição parcial do cimento
In the state of Acre, Brazil, traditional fine and coarse grain aggregates are used. By the way, the concrete materials proportioning (of that region, as well as of all regions) aim to reach the better quality (strength, durability) instead of costs. This paper offers data for a rational concrete dosage using sand of the Rio Acre, granite aggregate from the

9. Management the project in Archaeology / Gestão em projetos de arqueologia
The Archaeology adopted a position of extreme importance nowadays and, especially, the archaeology of projects linked to the impacted enterprises for the environment by reason of exigencies of Brazilian Legislation. That growth has favored the appearance of new projects and different views about the archaeological science and the Brazilian cultural patrimony

12. Estudo do comportamento do concreto no estado fresco contendo areia britada
The crushed sand possesses different characteristics from the natural one, mainly due to the high fine materials contents, particle size distribution, shape, roughness and lithological types. It is formed during the process of comminution of rock, and its able to suffer classification and improvement of the particles shape. Such characteristics affect, in la
