U.S. spent nuclear fuel, economic asymmetries, and the data center electricity demand challenge
No full textThe renewed interest in commercial nuclear energy to potentially satisfy increasing electricity demand requires solving the policy and regulatory impasse in backend fuel cycle management. This paper fills a gap in the literature by providing a technical and quantitative analysis of material flows under various fuel cycle options and linking the latter to associated financial costs. Under current U.S. law the government is responsible for spent nuclear fuel management, which exacerbates industry specific environmental, informational, intergenerational, and economic asymmetries, this led to policy failure, and enormous costs borne by U.S. taxpayers. The paper is structured as follows. Section 1 provides an introduction. Section 2 reviews current literature. Section 3 provides some technical background. Section 4 presents a brief historical account of regulatory challenges, and an overview of legacy spent nuclear fuel. Section 5 presents the methodology, data used, and scenario selection. Section 6 develops scenarios 1-4. Section 7 discusses the results and section 8 concludes the paper and provides policy recommendations. We find that spent nuclear fuel management could cost taxpayers as much as 11.3 billion. Policy recommendations to mitigate industry specific asymmetries, and lower costs to taxpayers are provided
Oncogenic transformation of tubular epithelial ducts: How mechanics affects morphology
No full textWe derive a continuum mechanical model to capture the morphological changes occurring at the pre-tumoral stage of epithelial tissues. The mathematical model, derived from first principles, accounts for the competition between the bulk elasticity of the epithelium and the surface tension of the apical and basal boundaries. The variation of the energy functional yields the Euler–Lagrange equations to be numerically integrated. The numerical results reproduce a variety of morphological shapes, from invagination to evagination, depending on the ratio between bulk and surface energy at variance of the length of the section. In particular, using parameters independently measured, we are able to reproduce experimental data reported for a ring partially made of transformed cells
Extremism as a symptom: for an alternative to therapeutic neoliberalism from Italian Theory
No full textThe rise of right-wingers, especially in the West, must be interpreted within the neoliberal art of government. It is the precariousness caused by the competitive market regime and the constant exposure of individuals to evaluation in every sphere of life that produces in the population an ever more widespread demand for security and control. The right-wingers take it upon themselves to provide a conservative response to this very demand, a response that serves above all to balance and compensate for the out-of-control drifts of neoliberalism, being functional to its preservation rather than representing an alternative to its crisis. On the crisis as an art of government, Italian thought has provided fundamental interpretations, starting with that of Antonio Gramsci, which is useful for understanding the current conjuncture, in which “extremisms” are a symptom of the crisis of neoliberal hegemony. On the level of a counter-hegemony stands Roberto Esposito’s immuno-politics as a possible alternative to the immunization inherent in the current therapeutic neoliberalism
«Parapis'ma» v «Zoo» V.B. Šklovskogo. Paratekstual'nye «porogi» kak narušenija ėpistoljarnogo kodeksa
No full textThis article explores the experimental structure of Viktor Shklovsky’s epistolary novel «Zoo, or Letters Not About Love», focusing on the interplay between letters and «paraletters» (inserted «prologues»). The author investigates Shklovsky’s mechanisms for deconstructing and renewing the canonical epistolary genre, highlighting his disruption of traditional literary codes.
The study begins with an analysis of Grigory Vinokur’s commentary, which notes the lack of adherence to established literary traditions in Shklovsky’s works. Drawing comparisons with Laurence Sterne’s texts, the article argues that Shklovsky deliberately manipulates the epistolary form by introducing paraletters that serve as metalinguistic devices, enhancing irony and parody. These inserted texts not only comment on and confirm the primary letters but also subvert their semantic and formal conventions.
A key focus of the research is the polyphonic nature of the novel, which emerges from the dynamic interaction between letters and paraletters. The author demonstrates how Shklovsky reassigns traditional roles in romantic correspondence, presenting the female character as a rational commentator and the male protagonist as a passionate lover. Particular attention is paid to the inversion of semantic clichés and the caricature-like subversion of epistolary elements, including hyperboles, puns, and distortions.
The analysis is limited to the first Berlin edition of the novel and concentrates on three primary aspects of the interplay between letters and paraletters: (1) manipulation of letter dates and locations, (2) inclusion of letters addressed to third parties, and (3) the polyphony and interweaving of voices
Current knowledge of the genus Chelidura Latreille, 1825 in the Alps, with descriptions of two new species (Dermaptera, Forficulidae)
No full textChelidura Latreille, 1825 is a genus of robust apterous earwigs with a Palaearctic distribution. Thanks to research carried out in Italy, Spain and France, the recent general reassessment of the European alpine species of Chelidura has clarified its distribution across Europe. Only one species, Chelidura aptera (von Charpentier, 1825), has been distinguished in the Alps so far, and we have subjected its populations to detailed morphometric and molecular analyses. The results revealed cryptic diversity and allowed us to define the presence of at least five species in the Alps: C. aptera (von Charpentier, 1825), C. montana (Gené, 1832), stat. nov., C. alpina (Gené, 1832), comb. nov., C. rhaetica sp. nov. and C. osellarum sp. nov. The diagnostic morphological characters of recognized species are described and illustrated, and an identification key for males of Western European Chelidura is provided.
The distribution of Chelidura species is patchy, with most occurring in subalpine and alpine zones at altitudes between 1,600 and 2,300 metres in the Alps. The occupied habitat is characterized by rocky landscapes with sparse vegetation. According to current knowledge, all recognized species exhibit allopatric distribution patterns, and their ranges do not overlap. The recent decline in the numbers of Chelidura specimens sighted at many historical localities may suggest possible local extinctions or a shift to higher elevations in response to environmental changes
Costruire per un grande evento: sostenibilità e futuro delle città
No full textOrganizzare un grande evento internazionale significa confrontarsi con un delicato
equilibrio tra infrastrutturazione, impatti ambientali, sostenibilità economica e
ricadute sociali. Le Olimpiadi invernali ne sono un esempio emblematico: accelerano
trasformazioni territoriali e generano opportunità, ma anche criticità legate al
consumo di risorse, alla temporaneità delle opere e alla loro capacità di essere
riutilizzate nel dopo-evento
