Toward ELF Magnetic Fields for the Treatment of Cancer
No full textThe possibility of a link between childhood leukemia and other cancers and extremely low-frequency magnetic fields has given rise to several epidemiological studies. The existence of amplitude and frequency windows prompts the need of screening through the different parameters of exposure for two reasons: optimization and avoidance of undesired effects. In principle, the most purist, safest way of going from experiments with cellular cultures to experiments with small animals and then finally to clinical trials with humans would be to use homogeneous fields in these several stages. In this way, dosimetry would be much easier, but the drawback would be substantial: for the treatment of humans, much bigger facilities should be used, in order to house devices big enough to generate homogeneous fields in a volume equal to or greater than a human being.Fil: Makinistian, Leonardo.

Data and platform co-ops in smart city citizenship: interview with Igor Calzada
No full textIgor Calzada is a senior researcher at universities like Oxford and Cardiff with a focus on urban, regional and technopolitical transformations, considering data issues and social innovation. In November 2020, he launched the book Smart City Citizenship, which proposes another framework at smart cities based on democratic governance and citizenship. Thus, he presents how it is possible to understand and intervene in technopolitical disputes involving algorithms, data, and artificial intelligence based on notions such as digital sovereignty. Among the possibilities, there is the creation of data and platform co-ops based on data and digital commons. For the author, data cooperatives are a subtype of platform cooperatives, in which they focus on business models, while data co-ops share and store data. The book analyzes, among other cases, the Barcelona ecosystem and proposes perspectives for public policies. Currently, Calzada is interested in exploring new models of data governance and artificial intelligence to propose alternative ways to data ecosystems in the European scenario. He defends experimental cities as a reaction to the mainstream idea of the city as a platform, as a reproduction of extractive and panoptic practices through hyperconnectivity. But it will be very difficult in a dangerous context. And he provokes: “how, in the current context, in which we are closed in our homes, can we propose cities with open systems? Other recommendations from the author are an article on platform and data co-ops published in Sustainability journal and a conversation in Spanish about social innovation in smart cities.

Introduzione a Igor Spanò (a cura di) Il Teatro e la festa. Il tempio, la piazza, la scena
No full textPer tre giorni gli studiosi che sono intervenuti al Convegno hanno riflettuto sul senso e sulle funzioni, sulle pratiche cultuali e rituali, sui luoghi che hanno definito nel corso del tempo i momenti della festa e sulle forme di rappresentazione agonistica (danze, corse, gare, giochi di abilità) o drammatica - di cui erano parte essenziale la musica e il canto - che, spesso intrinsecamente, li accompagnano. L'autore nella sua introduzione esamina le sfumature di significato che racchiude il termine utsava, “festa”, “gioia” in sanscrito.For three days the scholars who spoke at the conference reflected on the meaning and functions, on the cult and ritual practices, on the places that have defined the moments of the celebration over time and on the forms of competitive representation (dances, races, competitions, skill games) or dramatic - of which music and singing were an essential part - which, often intrinsically, accompany them. In his introduction, the author examines the nuances of meaning contained in the term utsava, "feast", "joy" in Sanskrit

DigiTranScope: the governance of digitally-transformed society
No full textThis volume presents the key outcomes and research findings of the Digitranscope research project of the European Commission Joint Research Centre. The project set out to explore during the period 2017-2020 the challenges and opportunities that the digital transformation is posing to the governance of society. We focused our attention on the governance of data as a key aspect to understand and shape the governance of society. Data is a key resource in the digital economy, and control over the way it is generated, collected, aggregated, and value is extracted and distributed in society is crucial. We have explored the increasing awareness about the strategic importance of data and emerging governance models to distribute the value generated more equitably in society. These findings have contributed to the new policy orientation in Europe on technological and data sovereignty and the sharing of data for the public interest. The digital transformation, the rise of artificial intelligence and the Internet of Things offer also new opportunities for new forms of policy design, implementation, and assessment providing more personalised support to those who need it and being more participative throughout the policy cycle. The use of digital twins, gaming, simulation, and synthetic data are just at their beginning but promise to change radically the relationships among all the stakeholders in governance of our society
Tõrked Eesti venekeelse kirjanduse omaks tunnistamisel 1918–1940. Igor Severjanini juhtum
No full textThe article looks at the history of Estonian Russian-language literature in the young Republic of Estonia (1918–1940) and the life and work of the Russian-speaking poet Igor Severyanin (1887–1941) from the perspective of Estonian literature. In 1918, Severyanin, as a mature author, moved permanently from Russia to Estonia. Gradually, he developed a hybrid identity: he became fond of Estonia and wrote in Russian. However, his works have been omitted from the Estonian literary history.
The article sets out the following hypotheses:
1) Estonian Russian-language literature from 1918 to 1940 has not become part of Estonian literature of that period, as its acceptance is hindered by various cultural-historical barriers for literary researchers. The main barriers have been highlighted by means of source criticism.
2) Igor Severyanin’s life and work serve to situate him as a representative of Estonian literature. Terms such as integration and identity were not used in his day, but Severyanin’s personal and creative choices help to understand, retrospectively, that it was important for him to live in Estonia, write poetry inspired by local material, interact with Estonian-speaking colleagues, remain connected with Estonian public and cultural institutions. I have approached Severyanin’s case through the identity theory (the work of John Charles Turner and Homi Bhabha), as well as Pierre Bourdieu’s concept of the literary field.
Both hypotheses were confirmed in the article. However, the values of modern multicultural society dictate that the discussion of Estonian literary history should include the Russian-speaking authors of the interwar period. Currently, there are gaps in Estonian literary history regarding these authors. Filling these gaps would mean overcoming the cultural-historical barriers
Compositions of Igor Stravinsky for Violin
No full textThe topic of my thesis is life and work of Igor Stravinsky with norrow focus on compositions for violin. I give greater emphasis to compositions Concerto in D for Violin and Orchestra and the Italian suite with which I have personal experience. Igor Stravinsky composed most of the compositions in the 1930th in cooperation with the violinist Samuel Duskin. Only a few of them are completely original works. The author often used musical themes from his own previously composed ballets, such as the The Firebird, Petrushka, The Soldier's Tale, Pulcinella, or Fairy's Kiss.
Composer Igor Stravinsky is certainly a controversial figure. Though essentially a pragmatist, he was always directed more by instinct while creating music. I would like to present to not only violinists interesting circumstances of compositions, even though is still little available informations
Effect of Intermittent ELF MF on Umbilical Cord Blood Lymphocytes
No full textHaving recently shown that intermittent extremely low frequency (ELF) magnetic fields (MF) inhibited proliferation of a cancer cell line, we wondered whether such fields could have some effect on normal blood cells. In order to test this, we exposed umbilical cord blood lymphocytes (UCBL) to MF with the same waveform (triangular, 7.8 Hz) and intermittence (250 s ON / 250 s OFF) during 48 h and 72 h, testing six amplitudes (between 6 µT and 24 µT) simultaneously in each experiment. We assessed percentages of viable, early apoptotic (EA) and late apoptotic/necrotic (LAN) cells, reactive oxygen species (ROS) production, and DNA double strand breaks (DSB) indicated by formation of 53BP1 and gamma-H2AX foci and their co-localization. No effect on DSB or ROS production was found for either exposure duration. However, a statistically significant decrease in viability occurred for field amplitudes below 17 µT after the 72-h exposure. It is remarkable that the effect appeared for field intensities below a certain threshold, strongly suggesting an amplitude window and thus the need of screening for different amplitudes of the same MF waveform.Fil: Zastko, Lucián.

POLITICAL GEOGRAPHY from Igor Okunev
No full textWho has the exact sovereignty to every particular piece of territory, water or air space on our planet? What is the status and the relationship between the states, political entities, dependent territories, international organizations and supranational unions? What is the true meaning of the term’s territorial identity, spatial identity and the political geography? It is with these questions that Igor Okunev opens his passionate plea of why we should care about the geo-politics or Political Geography as he names it. Contrary to popular belief, the author argues, "the spatiality of politics is determined by factors beyond objective ones.
