3. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

4. Photo-induced dipole relaxation current in natural Amethyst
Thermally stimulated depolarization current (TSDC) measurements were carried out for SiO2 in the amethyst form, aiming to investigate the relationship of observed current with relaxation phenomena related to quartz impurities. In addition to TSDC conventional dark procedure, photo-induced TSDC was also carried out, where the exciting light came from an Ar+ l

5. Pequenos polarons ligados e centros de cor em topázio
In the present work we studied the color beneficiation processes of colorless topaz, an abundant gemstone in Brazil. Blue topaz is the most internationally traded gemstone in the gem and market, reaching about 100 million carats per year. Almost 100% of blue topaz received some treatment to improve the color that, generally, involves some type of irradiation

6. Infrared and chemical characterization of natural amethysts and prasiolites colored by irradiation
The infrared bands of amethyst and prasiolite samples from different origins were correlated to the trace elements contents. Amethysts have an iron content greater than 20 ppm and a low content of sodium and potassium. Prasiolites have an aluminum content greater than 120 ppm and a higher overall trace elements content, which accounts for a strong absorption

7. A luz alem da visão : iluminação e sua relação com a saude e bem-estar de funcionarias de lojas de rua e de shopping centers em Porto Alegre / The light beyond vision : lighting and its relationship with health and well-being of employees at street and shopping mall retail stores in Porto Alegre
This work addresses the issue of non-visual impacts of human exposure to light, in an attempt to relate the quality of lighting to health, comfort, and well-being of female retail store employees. The sample for the cross-sectional study was randomly established with female volunteers. Three groups were selected: street retail stores with outside contact and

8. Caracterização de Ametistas Naturais
This research intends to investigate the formation of color in samples of natural amethyst from different origins after submitting them to gamma irradiation, as well to develop an identification method of uncolored crystals with potential for development of color. The techniques of infrared spectroscopy, ultraviolet-visible spectroscopy and atomic emission s

9. Segmentação de pele humana em imagens coloridas baseada em valores das médias da vizinhança em subimagens / Segmentation of human skin in colored images based on the average of neighborhoods in sub-images
The segmentation of human skin, in colored images, has been studied broadly for the last years serving as foundation for many other studies as, for instance, the detection of faces. Among the countless applications of works related to the segmentation of human skin it is the one of localizing a certain person in places of great human concentration such as: a

10. Thermoluminescence, electron paramagnetic resonance and color centers properties of diopside / Propriedades de termoluminescência, de ressonância paramagnética eletrônica e de centros de cor de diopsídio
Diopside of chemical formula, CaMgSi2O6, a natural silicate mineral has been investigated concerning its Thermoluminescence (TL), Electron Paramagnetic Resonance (EPR) and Reflectance properties. Synthetic, pure or doped diopside, produced in the laboratory, has been investigated. Samples annealed at 600 `GRAUS´ C for one hour, to eliminate previously induc

12. Filtração lenta em areia, manta não tecida e carvão ativado como pós-tratamento de efluentes domesticos e reuso / Slow sand filtration with non woven syxthetic fabric and activated carbon as after treatment of domestic sewer effluent and reuse
The slow sand filtration is a viable economic alternative for small communities moved away from the great urban centers. This work evaluated the efficiency of a slow filter with sand layer, activated carbon and non-woven synthetic fabric, compared with a slow filter of sand and non-woven synthetic fabric to treat constructed wetland effluent. The results had
