1. Study on patient dosimetry and image quality in digital mammography
Abstract Introduction Digital mammography present many advantages in comparison to conventional mammography, such as high dynamic range and the post-processing of acquired images. One problem is that protocols may not be optimized, resulting in higher absorbed doses to patients. The objective of this work is to evaluate image quality and to estimate mean gl

2. Behavior of surface integrity in cylindrical plunge grinding using different cooling systems
The superficial texture of the material can exert a decisive influence on the application and performance of the machined component. The conventional fluids used in grinding processes are environmental risk and can also be dangerous to the health. The disposal of these toxic fluids is expensive and the contamination in the proximities of the machines can pre

4. Análise de eficiência energética em sistemas de ar comprimido
The compressed air systems represent plot expressive of energy consumption of an industrial plant. However, the lack of an appropriate project and a regular maintenance causes reduction in the overall performance featuring a constant source of waste. This fact guided the subject of this dissertation research, which is directed towards the development and app

6. Metabolismo de nitrogenio em plantas de soja [Glycine max (L.) Merr. cv IAC-17] submetidas a deficiencia de O2 no sistema radicular
The soybean (Glycine max (L.) Merr.) is among the most frequently used models to study O IND.2 deficiency in the root system of plants. However, few studies have focussed on waterlogging of the root system and its effects on the metabolic content of the roots, especially nitrogenous compounds, and their means of transportation through the xylem and phloem.
