Power Bus Management Techniques for Space Missions in Low Earth Orbit
2021
In space vehicles, the typical configurations for the Solar Array Power Regulators in charge of managing power transfer from the solar array to the power bus are quite different from the corresponding devices in use for terrestrial applications. A thorough analysis is reported for the most popular approaches, namely Sequential Switching Shunt Regulation and parallel-input Pulse Width Modulated converters with Maximum Power Point Tracking. Their performance is compared with reference to a typical mission in low Earth orbit, highlighting the respective strengths and weaknesses. A novel solar array managing technique, the Sequential Maximum Power Tracking, is also introduced in the trade-off a…

(Re-)examining horizons in feminist translation studies: towards a third wave
2009
This article is an English version of "(Re)examinando horizontes en los estudios feministas de traducción: ¿hacia una tercera ola?" by Olga Castro, which was first published in MonTI 1 (2009), pp. 59-86. It was not included on the print version of MonTI for reasons of space. The online version of MonTI does not suffer from these limitations, and this is our way of promoting plurilingualism and internationalism. Feminisms are one of those framework theories that have contributed powerfully to all areas of society, including Translation Studies. The most evident outcome of this interplay is the emergence, in the 1980s, of a Feminist Translation school in Canada, which placed gender in the spo…
2nd and 3rd graders' attitudes towards the English language : attitudes before and after studying English at school
2014
Oppilaat aloittavat Suomessa englannin opiskelun useimmiten 3. luokalla. Englannin kieli on kuitenkin vahvasti läsnä Suomessa esimerkiksi mediassa ja ulkomaalaisten kautta. Monet perheet myös matkustavat ulkomaille. Siksi onkin syytä olettaa, että lapsilla on asenteita englannin kieltä kohtaan jo ennen kuin he aloittavat sen opiskelun koulussa. Asenteilla on suuri merkitys englannin kielen oppimistuloksien kannalta. Tämän tutkimuksen tavoitteena oli tutkia millaisia asenteita lapsilla on englannin kieltä kohtaan 2. luokan keväällä ja kuinka asenteet ovat muuttuneet 3. luokan kevääseen mennessä, kun he ovat opiskelleet englantia suurin piirtein yhden lukuvuoden verran. Tutkimus käsittelee my…
Toward evidence-based severity assessment in rat models with repeated seizures: II. Chemical post-status epilepticus model.
2019
Objective: Considering the complexity of neuronal circuits and their epilepsy-associated alterations, epilepsy models cannot be completely replaced by in vitro experimental approaches. Decisions about ethical approval of in vivo studies require a thorough weighing of the animal's burden and the benefit regarding the expected gain in knowledge. Methods: Based on combined behavioral, biochemical, and physiological analyses, we assessed the impact on animal well-being and condition in different phases of the pilocarpine post–status epilepticus (SE) model in rats. Results: As a consequence of SE, increased levels of impairment were evident in the early postinsult phase and late chronic phase, w…
Third-harmonic generation in optical microfibers: From silica experiments to highly nonlinear glass prospects
2012
International audience; Using optical microfibers, phase matching between different propagation modes allows for third-harmonic generation (THG). After detailing the relevant phase matching conditions and overlap integrals, we provide a comparison between THG effective efficiencies in silica and tellurite glasses. We also explain the relatively easy, wideband, conversion that we observe experimentally in silica glass microfibers, from 155 mu m to the green, by the geometry of the tapering region.
Władze Rzeczypospolitej Polskiej na uchodźstwie wobec sytuacji w Polsce w latach 1947–1949
2018
The authorities of the Republic of Poland in exile tried to follow and analyse the situation in Poland after World War 2. The developments in the years 1947–1949 which aroused particular interest among emigrants were the elections to the Legislative Sejm, the issue of the Oder-Neisse borderline and the sovietisation of Poland. These topics were raised by the president in his speeches, by the government during its meetings and by the National Council of Poland during its sessions. The authorities in exile did not manage, however, to exert influence upon the situation in Poland. Because of the political isolation of the government of the Republic of Poland in exile, emigrants could merely sta…
The balancing act of teaching : a comparison between EFL teachers' views and a textbook analysis of the role of perceptual learning styles in Finnish…
2012
Suomessa vieraan kielen opiskelu aloitetaan tavallisimmin kolmannella luokalla, ja suurimmalle osalle oppilaista tämä kieli on englanti. Tällöin oppilas alkaa rakentaa kuvaa sekä englannin kielestä että itsestään englannin kielen opiskelijana. Onnistumisen kokemukset ovat tässä vaiheessa tärkeitä, ja yksi tapa niiden mahdollistamiseen on oppilaan oppimistyyliä vastaava opetus. Kolmannen luokan englannin oppitunneille osallistuu kuitenkin heterogeeninen ryhmä erilaisia oppijoita, minkä vuoksi on käytettävä vaihtelevia opetusmenetelmiä. Tässä tutkimuksessa keskityttiin seuraaviin oppimistyyleihin: visuaalinen, auditiivinen, kinesteettinen, taktiilinen sekä ryhmässä ja yksin oppiminen. Näistä …
