Different Measurement Setup Configurations for Space Charge test in Mini Cable Specimens with the PEA Method
2019
Under DC stress, the space charge accumulation is believed one of the most responsible of dielectrics ageing. For this reason, due to the increase of the HVDC transmission, a recommendation has been proposed. The latter want to introduce the space charge measure, with the PEA method, in cable specimens during the prequalification or type tests. Considering the several issues related to this kind of measures the aim of the proposed work is find a measurement setup for mini cable specimens which is able to provide a clear and clean space charge profile. Therefore, different tests have been made in this work. In particular, the length of the cable specimen, the width of the pulse electrodes, a…
A new approach to calibrate the thermal conditions in space charge measurements on HVDC mini-cables
2019
The PEA method is currently widespread used for space charge measurements in mini-cables in order to qualify the behavior of semicon-dielectric-semicon compound under electric and thermal stress. The main goal of this research is to quantitatively evaluate the relationship between the thermal boundary conditions applied to cables or mini-cables and the maximum local electric field due to the accumulated space charge. Hitherto, several research groups have obtained thermal gradients over the dielectric's radius heating the conductor by Joule effect due to an induced current. In this paper, a numerical approach is offered to calibrate the heat exchange boundary conditions to apply to a sample…
The division of domestic work among dual-career and other dual-earner couples in Finland
2015
This study compares the division of domestic work among dual-career and other dual-earner couples. We examine whether gender attitudes, relative resources and working time explain the differences between dual-career and other dual-earner couples. We define dual-career couples as those in which both spouses are professionals and/or managers. The division of housework is important for these couples because of the intense pressures of work. We hypothesise that domestic work is more equally shared among dual-career couples than among other dual-earner couples. The quantitative analyses are based on the Finnish data from the 2010 European Social Survey (N = 493). The qualitative data consist of …
Vertical Line Array (VLA) Beam - Forming Algorithm with constant beam width.
2005
The algorithm proposed is a beam-forming algorithm. Many beam-steering and beam-forming algorithms exist and they are all based on the control of delay times between the signals driving the loudspeakers of the line array; this kind of control produces a variable beam-width depending on steering angle and frequency. In our case beam width doesn't depend on frequency and steering angle because a specific beam forming technique was applied by shading the amplitudes of signals for each element of the array according to the frequency applied. Furthermore a weighting function was utilized for spatial windowing. Spatial windowing allows reduction of secondary lobes without varying the directivity …
Les bizutages dans le monde ouvrier en France à l’époque contemporaine
2013
Dans le monde ouvrier, des pratiques informelles de bizutage se reperent, accomplies par des hommes comme par des femmes sur les jeunes jusque vers les annees 1970 environ, pour accompagner leur entree dans les usines. Elles fonctionnent a la fois comme rites de passage, manifestations brutales de domination voire de violence, et blague dont il convient de rire. Mais, parce qu’elles revetent une dimension sexuelle manifeste, elles participent de l’identification des masculinites ouvrieres a la virilite.
Monilukutaidon opetus on ennen kaikkea uusien kirjoitustaitojen opetusta
2014
Täysipainoinen osallistuminen tulevaisuuden yhteiskuntaan vaatii paljon laajempia kirjoitustaitoja kuin koulun kirjoittamisen opetus tällä hetkellä tarjoaa. Uusiin opetussuunnitelmiin tuleva monilukutaito voi tarjota väylän näiden uusien kirjoitustaitojen opiskeluun, mikäli aktiiviseen osallistumiseen ja luovaan sisällöntuotantoon ohjaavat uudet kirjoitustaidot nostetaan tasaveroisesti uusien lukutaitojen rinnalle. Uudistuksella on kuitenkin jo kiire, sillä oppilaat elävät vapaa-ajalla pitkälti jo uusien kirjoitustaitovaatimusten keskellä. nonPeerReviewed

In pursuit of beginning teachers'competence in promoting reading motivation: a mixed-methods study into the impact of a contunuing professional devel…
2020
As teachers’ reading motivation and self-efficacy for promoting reading motivation can be considered vital for their reading-oriented promotive teaching practices and students’ reading motivation, this study evaluated the impact of a year-long CPD program for beginning primary school teachers. A convergent parallel mixed-methods design with repeated measures was established, including a comparison and two CPD conditions (group vs. individually-oriented). Based on the quantitative results only no clear impact of and differences between the conditions could be observed. The qualitative analysis, however, showed growth in teachers’ reading motivation and self-efficacy at a different pace and l…
La garantía del derecho al olvido: protección de datos, retos futuros y propuestas de regulación de situaciones de vulnerabilidad en la Unión Europea
2020
El actual desarrollo tecnológico y la transformación digital han posibilitado la recogida, almacenamiento, análisis, utilización e intercambio masivo e ilimitado de información de carácter personal. Esto plantea nuevos desafíos asociados a la tutela y efectividad de los derechos fundamentales, en particular del derecho a la protección de datos de carácter personal. Uno de estos retos, en clave cibernética y jurídica, es la perpetuidad y accesibilidad universal, en la Red Internet, de información personal, potencialmente lesiva para el libre desarrollo y la dignidad. Considerando la compleja realidad tecnodigital, así como la pluralidad ordinamental de las NTIC, se hace necesaria una revisió…
Ecclesial Goals of the ”First Oration of Peace” by Gregory of Nazianzus
2020
Spośród trzech mów na temat pokoju pierwszą z nich Grzegorz z Nazjaznu wygłosił najprawdopodobniej w lutym 364 r. Jej wątkiem wiodącym było przywrócenie pokoju i zgody u zwaśnionych stron we wspólnocie kościelnej Nazjanzu. Powodem sporu okazało się opaczne złożenie podpisu przez Grzegorza Starszego pod wyznaniem wiary, które było w tej miejscowości rozpowszechniane przez ariańskiego przedstawiciela. Dla mówcy podłożem do przywrócenia pokoju były wspólne idee łączące zwaśnione strony, czyli wiara w jednego Boga, zgodne interpretacje zagadnień trynitarnych i pragnienie jedności. Pokój, o który zabiegał Grzegorz, okazał się wartością jednoczącą wszystkich tworzących społeczność kościelną w Naz…
