The significance of perceptions and cultural engagement in the evolution of a European commercial and soft power diplomacy with the emerging Asian giants
Published 2017“…The focus of my submission is on external perceptions of Europe from the perspectives of the two new great powers in Asia: China and India. It spans over nine years of research. When the work started in 2006, the EU was in deep crisis just a year after the uncertainty that was unleashed by the rejection in France and the Netherlands of the then Constitutional Treaty. …”

A pilot study on peptidylarginine deiminases and protein deimination in animal cancers across vertebrate species
Published 2022“…Immunohistochemical analysis revealed that CitH3 was strongly detected in all of the cancers assessed, while pan-deimination detection was overall low. Both PAD2 and PAD3 were the most predominantly expressed PADs across all of the cancers assessed, while PAD1, PAD4, and PAD6 were overall expressed at lower, albeit varying, levels. …”

Design of microstrip ultra wide band antenna with two notch filters for wireless communication
Published 2015“…In order to add reconfigurable characteristics to the patch antenna, two copper strips are putted on the slots to represent the ON and OFF switching status of an ideal Pin diode. By using this simple switching technique, the current distribution of the patch changes and enables the antenna to have four modes of operation. …”

Cancer control and prevention in Argentina
Published 2019“…From the 1920s to the early 1980s, three distinct periods can be identified: first, an institutional approach, where the first cancer institute attempted to concentrate all the activities related to the control of cancer, that is, lay education, scientific research, diagnosis and treatment, patients’ support, and cancer statistics; second, a state approach, inaugurated by the arrival of Juan Domingo Perón to government, where the centralization of cancer initiatives became a state affair; and third, a long period characterized by the retirement of the state—marked by political unrest and a succession of military governments until the return of democracy in 1983—informed by decentralizing policies, the prominent role of civil society actors, such as voluntary organizations and medical societies, and the relative sway of the Pan American Health Organization. Throughout these three periods, all these actors played a role, and their ambivalent relationship and, often poor, interaction shaped the country’s efforts to control and prevent a disease that, since the 1940s, has steadily occupied the second cause of death. …”

Novel opto-electronic and plastic fibre sensors
Published 1998“…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”
