Bi-2212 and Y123 highly curved single-crystal-like objects: whiskers, bows and ring-like structures
2012
High-temperature superconducting objects of Bi2Sr2CaCu2O8 and Y Ba2Cu3O7 highly curved in the ab-plane, such as curved/kinked whiskers, bows and ring-like structures, were obtained within a solid?liquid?solid (SLS) grass-like growth mechanism. As-grown objects are crystals with three-dimensional epitaxy similar to conventional single crystals: they can be viewed as crystal parts ?cut? from a conventional rectangular crystal. Between our curved objects and conventional crystals, whiskers or thin films there are some differences in the superconducting properties induced only by the shape factors and no new physics is observed. Some details of the growth mechanism are discussed, emphasizing cu…
Systemic blockade of ACVR2B ligands attenuates muscle wasting in ischemic heart failure without compromising cardiac function
2020
Signaling through activin receptors regulates skeletal muscle mass and activin receptor 2B (ACVR2B) ligands are also suggested to participate in myocardial infarction (MI) pathology in the heart. In this study, we determined the effect of systemic blockade of ACVR2B ligands on cardiac function in experimental MI, and defined its efficacy to revert muscle wasting in ischemic heart failure (HF). Mice were treated with soluble ACVR2B decoy receptor (ACVR2B-Fc) to study its effect on post-MI cardiac remodeling and on later HF. Cardiac function was determined with echocardiography, and myocardium analyzed with histological and biochemical methods for hypertrophy and fibrosis. Pharmacological blo…
Lwowski debiut Tomasza Augusta Olizarowskiego
2020
Tomasz August Olizarowski, born on March 10, 1811 in Wojsławice, in Galicia, still be- longs to the group of the unknown and unjustly forgotten poets and playwrights. One hundred and thirty five years have passed since his death, and so far there has been neither a critical edition of his rich literary output, nor a monograph devoted to him. Most of his texts remain in manuscripts collected at the Polish Library in Paris and at the Library of Kórnik. The latter holds among its collections the first volume of his Psalms, most probably published by the poet in L’viv in 1832, compared by an unknown 1833 reviewer to the works of Jean Paul (Johann Paul Friedrich Richter) and even to J.W. Goethe’…
Incarcerated women, welfare services and the process of re-entering society in Finland
2020
The pathways in and out of crime differ according to gender, people’s life histories, social situations and networks. Before being sentenced, many women have been living in vulnerable and traumatic life situations and violent relationships. Substance abuse often plays a crucial role in committing crimes. Being released from prison and re-entering society is a process that requires women’s own motivation to desist along with help and support from society. This chapter shows how women narrate and describe their experiences after being released from prison and especially how they report the ways in which the welfare system responds to their needs. They discussed their needs for support and ser…

La gestione dell’inadempimento contrattuale negli smart contract
2022
Il contributo ha l’obiettivo di prospettare soluzioni giuridiche alla gestione delle sopravvenienze contrattuali negli smart contract, ipotesi che sembra in contrasto con la loro rigida struttura, che dà luogo all’automatica esecuzione degli stessi. Strumentale è anche il confronto con il sistema giuridico tedesco, grazie al quale si avvalora la tesi che gli smart contract non sono una nuova tipologia contrattuale, ma una formazione digitale dello stesso, al quale però vanno applicati sia i principi generali del contratto sia soluzioni giuridiche già esistenti, benchè adattati all’ultima evoluzione tecnologica, sempre più incline alla dematerializzazione del contratto.
The Role of Corporate Social Responsibility (CSR) in the New Economy
2004
The idea of corporate social responsibility has come to be accepted as one of the major components of business growth and sustainability. The success in the new economy comes with various challenges. Those challenges require business and their managers to think beyond traditional way of looking for short-term goals. It requires business and the people inside these behemoths to embrace a much broader perspective that is also inclusive of stakeholders. The nature of society we are living in has changed. The nature of governance has equally changed since people are now enjoying more freedom within each societal democratic tenet. This freedom has found its way in the business and into the facto…
Data practices and inequality in South African early childhood development policy: Technocratic management versus social transformation
2019
Background: In 1994, the African National Congress identified early childhood development as a potential strategy to redress the inequalities of apartheid, however, two and a half decades later, poverty still persists, and South Africa is one of the most unequal countries in the world. Aim: This article explores how policy texts based on and with the use of certain data practices establish ‘truths’ about childhoods and society, construct families and communities, and determine forms of provision to address inequality. Setting: In 2015, the South African government published the National Integrated Early Childhood Policy (NIECDP) to continue to address poverty and inequality. Its implementat…
Au revoir Paris! Spanish regions closer to the EU average and further away from the leaders
2021
This paper confirms that Spanish regions in 2015 were closer to the EU average in labour productivity than in 2000, but further away from the richest regions such as Île de France. A dynamic shift-share analysis at a 10-industry level of disaggregation shows that the main driver of convergence with the EU average is catch-up in labour productivity within the same industry, while disparities with the top regions (especially Île de France) mainly involve differences in patterns of specialization (between-industry divergence) followed by technological divergence (within-industry effect). The industry mix of the regions reveals that a new pattern of specialization is taking shape in Europe, dri…
Trapped Ion Oscillation Frequencies as Sensors for Spectroscopy
2010
The oscillation frequencies of charged particles in a Penning trap can serve as sensors for spectroscopy when additional field components are introduced to the magnetic and electric fields used for confinement. The presence of so-called "magnetic bottles" and specific electric anharmonicities creates calculable energy-dependences of the oscillation frequencies in the radiofrequency domain which may be used to detect the absorption or emission of photons both in the microwave and optical frequency domains. The precise electronic measurement of these oscillation frequencies therefore represents an optical sensor for spectroscopy. We discuss possible applications for precision laser and microw…
