Human breast tissue cancer diagnosis by Raman spectroscopy

Abstract. Differences between Raman spectra of normal, malignant and benign tissues have been recorded and analyzed as a method for the early detection of cancer. To the best of our knowledge, this is one of the most statistically reliable research (67 patients) on Raman spectroscopy-based diagnosis of breast cancers among the world women population. The paper demonstrates that Raman spectroscopy is a promising new tool for real-time diagnosis of tissue abnormalities

Measurement and comparison of individual external doses of high-school students living in Japan, France, Poland and Belarus -- the "D-shuttle" project --

Twelve high schools in Japan (of which six are in Fukushima Prefecture), four in France, eight in Poland and two in Belarus cooperated in the measurement and comparison of individual external doses in 2014. In total 216 high-school students and teachers participated in the study. Each participant wore an electronic personal dosimeter "D-shuttle" for two weeks, and kept a journal of his/her whereabouts and activities. The distributions of annual external doses estimated for each region overlap with each other, demonstrating that the personal external individual doses in locations where residence is currently allowed in Fukushima Prefecture and in Belarus are well within the range of estimated annual doses due to the background radiation level of other regions/countries

Volta ao mundo por ouvir-dizer: redes de informação e a cultura geográfica do Renascimento

This paper shows what an important role Renaissance culture played in shaping the mindset of modern travelers thanks to its focus on observation, curiosity and the pursuit of intellectual refinement. Another peculiarity of this historical period is the use of geographic knowledge for strategic purposes. However, the official secrets, homologated by the Casas de Contratación (entities set up by Spain to control colonial trade), went through a continuous process of corrosion. The need of the Portuguese and Spanish Crowns to ratify their possession of new colonial territories made the disclosure of such information as important as silence. Furthermore, the experience of the Discoveries was assimilated by second¿hand informers and shared through diplomatic and commercial channels that branched out across Europe. This collective and non¿official organism - or "network" as we might call it today - made data relative to Asia, Africa and America available to cosmographers, thus constituting a firm basis for 16th¿century cartography. The paper is an effort to show that the flow of geographic knowledge during the Age of Discoveries was characterized by a virtually unrestricted practice of copying and by a circuit of consumption that was both informal and international
