  1. 16. Brash Ice and Level Ice Growth, Effects of Snow

    Författare :Vasiola Zhaka; Andrzej Cwirzen; Kaj Riska; Robert Ettema; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brash ice growth; level ice growth; snow effects; slush; snow ice; macroporosity; piece size distribution; Byggmaterial; Building Materials;

    Sammanfattning : Brash ice occurs due to frequent navigation in ice-infested waters, typically along established navigation tracks regularly maintained by icebreakers and harbors. The accumulation and consolidation of brash ice between two ship passages are influenced by meteorological factors including the cumulative freezing air temperatures, and the mechanical processes such as ice-breaking due to ship passages.

  3. 17. Partial Discharges Studied with Variable Frequency of the Applied Voltage

    Författare :Hans Edin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diagnostic methods; partial discharges; phase resolved; variable frequency; dielectric spectroscopy; dielectric response; harmonics; insulation; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Sammanfattning : This thesis concerns partial discharge (PD) diagnostics withvariable frequency of applied voltage in the frequency range 1mHz - 400 Hz. The exploration of a new type of spectroscopythat combines partial discharge analysis and dielectricresponse is demonstrated. LÄS MER

  4. 18. Cellular effects of ionizing radiation : Relevant for understanding cancer risk after medical and environmental radiation exposures

    Författare :Pamela Chiaka Akuwudike; Andrzej Wojcik; Lovisa Lundholm; Kerstin Borgmann; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiation; DNA damage; radiation-induced carcinogenesis; second primary cancer; cisplatin chemoradiotherapy; dose fractionation; low dose; low dose rate; dose and dose rate effectiveness factor DDREF ; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Radiation-induced cancers are stochastic and delayed effects of exposure to ionizing radiation. The dose-response relationship for radiation-induced cancers at both low dose/low dose rates and high doses (doses encountered during radiotherapy) remains unclear. LÄS MER

  5. 19. L’accordo nell’italiano parlato da apprendenti universitari svedesi : Uno studio sull’acquisizione del numero e del genere in una prospettiva funzionalista

    Författare :Anna Gudmundson; Camilla Bardel; Ineke Vedder; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; second language acquisiton; L2; gender; number; agreement; Italian; frequency effects; competition; form function mapping; validity; corpus; italienska; Italian;

    Sammanfattning : This study investigates the acquisition of grammatical gender and number agreement in Italian as a second language (L2). The theoretical framework is based on a functional approach that stresses the importance of form function mappings, cues, frequency effects and the statistical properties of the language input.

  7. 20. Le langage préfabriqué en français parlé L2 : Étude acquisitionnelle et comparative

    Författare :Fanny Forsberg; Inge Barting; Florence Myles; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Formulaic Language; Formulaic Sequences; L2 acquisition; spoken French; Prefabs; InterFra corpus; Frequency Effects; Lexical prefabs; Discourse prefabs; idiomaticity; holistic learning; overuse underuse; verb morphology; French language; Franska språket;

    Sammanfattning : This study investigates the use of formulaic language in spoken French produced by native and non-native speakers. It aims at describing the development of formulaic sequences in learners ranging from beginners to very advanced users. It draws on data from the InterFra corpus, which includes both formal and semi-formal learners. LÄS MER
