Critical-state effects on microwave losses in type-II superconductors
2006
We discuss the microwave energy losses in superconductors in the critical state. The field-induced variations of the surface resistance are determined, in the framework of the Coffey and Clem model, by taking into account the distribution of the vortex magnetic field inside the sample. It is shown that the effects of the critical state cannot generally be disregarded to account for the experimental data. Results obtained in bulk niobium at low temperatures are quantitatively justified.
A Different Role of Taxation. From a One-Sided Taxation To a Circular Taxation
2020
The essay explores a possible different use of tax revenue, that is a perspective in which taxation is linked to a public choice in a circular way, thus determining a shift from the traditional “one-side taxation” process to a “circular taxation” process. Starting from the widely studied juridical phenomenon, known in Italy as regeneration of common spaces and goods or simply “regeneration”, and addressing the case of the regeneration of a brownfield, the Author argues that this phenomenon shows some common points with the so-called “circular economy”, since they are both inspired by the same principle of making resources usable in a circular context, exploiting already existing goods and r…
Revising the history of Nitchevo with text archives
2022
This article focuses on the way nitchevo, a nineteenth-century Russian borrowing, was adopted into the English language. In order to investigate the history of the word, six digital text archives were considered. The results of the research are promising: not only do they allow one to trace antedatings for both senses, which updates the treatment of nitchevo in the Oxford English Dictionary (OED), but they also shed light on its semantic development, spelling variation, and route of transmission. Tellingly, albeit unsurprisingly, the evidence suggests that the press is responsible for boosting the recognition of the word on both sides of the Atlantic. All this indicates that the potential o…
Zator tętnicy środkowej siatkówki jako pierwsza manifestacja kliniczna w postaci powikłania zatorowo-zakrzepowego jednopłatkowej zastawki aortalnej—o…
2018
Jednopłatkowa zastawka aortalna (UAV) jest rzadką wrodzoną wadą zastawki aortalnej. Przegląd literatury sugeruje, że szacowana częstość jej występowania wynosi 0,02%. W artykule przedstawiono przypadek 40-letniego pacjenta z UAV z ciężką stenozą. Etiologia jednopłatkowej zastawki aortalnej jest najczęściej wrodzona, jednak w opisanym przypadku rozpatruje się ją na dwóch możliwych podłożach — jako wadę wrodzoną o podtypie slit-shaped unicomissural lub jako wadę nabytą o degeneracyjnej postaci zwężenia zastawki. Pierwszą manifestacją choroby u pacjenta było powikłanie zakrzepowo-zatorowe w postaci zatoru tętnicy środkowej siatkówki objawiające się nagłym zaniewidzeniem. Chorego skierowano na …
Renewable Energy Technologies for Economic Development

Indonesian villages are facing dangerous condition. Every year, young people are deserting the villages. To overcome this problem, Tangsi Jaya hamlet, West Java, has been provided with 18 kW micro-hydro to supply electricity both to the community and to Small Processing Center for ground coffee production. Results of cash flow analysis for ground coffee in Tangsi Jaya hamlet, with total investment of IDR 110 750 000 and discount rate of 18 % for 5 yr. Banyumeneng I hamlet, Yogyakarta with an investment cost IDR 95 000 000 and production cost of IDR 34 195 000 yr–1 and the interest rate of 14 % yr–1, the payback period was estimated to be 3 yr with ROI of 40 %. PEST analysics indicate that t…
On the trail of local welfare innovations in rural Finland
2019
Final Draft In Finland, the rural areas have been most affected by the developments threatening the survival of the welfare state as well as by conflicting efforts to save it. However, there are rural communities that have—as a response to the mainstream policy emphasizing economic efficiency and individual responsibility—developed innovative solutions to secure their welfare. Based on a case study focusing on two of such communities, these local welfare innovations are a result from a combination of external causes and local resources including the sense of community and a diverse enough community structure. The authors argue that in the context of welfare policy, the promotion of local we…
Neuronal Growth and Behavioral Alterations in Mice Deficient for the Psychiatric Disease-Associated Negr1 Gene
2018
Neuronal growth regulator 1 (NEGR1), a member of the immunoglobulin superfamily cell adhesion molecule subgroup IgLON, has been implicated in neuronal growth and connectivity. In addition, genetic variants in or near the NEGR1 locus have been associated with obesity and more recently with learning difficulties, intellectual disability and psychiatric disorders. However, experimental evidence is lacking to support a possible link between NEGR1, neuronal growth and behavioral abnormalities. Initial expression analysis of NEGR1 mRNA in C57Bl/6 wildtype (WT) mice by in situ hybridization demonstrated marked expression in the entorhinal cortex (EC) and dentate granule cells. In co-cultures of co…
Association between osteocalcin and cognitive performance in healthy older adults.
2016
INTRODUCTION: cognitive deterioration and reductions of bone health coincide with increasing age. We examine the relationship between bone composition and plasma markers of bone remodelling with measures of cognitive performance in healthy adults.METHODS: this cross-sectional study included 225 old (52% women, mean age: 74.4 ± 3.3 years) and 134 young (52% women, mean age: 23.4 ± 2.7 years) adult participants from the MyoAge project. Whole body bone mineral density was measured by dual-energy X-ray absorptiometry. Blood analyses included a panel of bone-related peptides (dickkopf-1, osteoprotegerin, osteocalcin (OC), osteopontin, sclerostin, parathyroid hormone and fibroblast growth factor …
Associations of IGF-1 and Adrenal Androgens with Cognition in Childhood
2019
Background: Little is known about the association between adrenarche and cognition in general populations of children. We therefore studied the associations of dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4), testosterone, insulin-like growth factor-1 (IGF-1), and adrenarche with cognition among prepubertal children. Methods: These cross-sectional analyses are based on baseline data of the Physical Activity and Nutrition in Children Study. A total of 387 children (183 girls, 204 boys) were included in the analyses. Raven’s Coloured Progressive Matrices (CPM) score was used to assess nonverbal reasoning. Serum adrenal androgens and IGF-1 concentrations were measured and clinical…
