  1. 16. Seasonal change in defensive coloration in a shieldbug

    Författare :Aleksandra I. Johansen; Gabriella Gamberale-Stille; Birgitta S. Tullberg; Graeme Ruxton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Shield bug; colour change; protective coloration; cryptic; aposematic; behavioural change; etologi; Ethology;

    Sammanfattning : Protective coloration such as aposematism and crypsis occurs in many insects but only a few species alter their defensive strategy during the same instar. We hypothesize the adult shield bug Graphosoma lineatum with an alternating black and non-melanised longitudinal striation exhibit such a change in defensive coloration. LÄS MER

  3. 17. Heat and Mass Transfer to a Single Particle in Fluidized Bed

    Författare :Gennadij I. Palconok; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transfer; turbulence; circulating fluidized beds; active particle; bubbling; heat; combustion; devolatilization;

    Sammanfattning : Heat and mass transfer to/from a single active particle in bubbling and circulating fluidized beds have been studied with application to fluidized bed combustion. A method of calculation of the heat and mass transfer coefficients in a bubbling fluidized bed (BFB) has been developed. LÄS MER

  4. 18. Airway protection and coordination of breathing and swallowing : in health and anesthesia

    Författare :Anna I. Hårdemark Cedborg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :pharynx;

    Sammanfattning : Swallowing and breathing is coordinated to ensure that the airway is protected from aspiration. During the pharyngeal phase of swallowing, breathing is interrupted to allow safe passage of bolus. However, details on the complex coordination of breathing and swallowing and their precise temporal relationship are not fully understood. LÄS MER

  5. 19. Företagande kvinnor i bruksort : arbetsliv och vardagsliv i samspel

    Författare :Mona Hedfeldt; Mats Lundmark; Gunnel Forsberg; Nina Gunnerud Berg; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bergslagen; women; regional gender contracts; small industrial towns; self-employment; entrepreneurship; work experience; role models; family; networks; Human geography; Kulturgeografi; Social and Economic Geography; Kulturgeografi;

    Sammanfattning : The Bergslagen region in Sweden has a history of iron and steel production, and in the small industrial towns in the region, one large employer has often held a strong position. Although the region has gone through structural change since the 1970’s, in previous research, becoming self-employed is perceived of as difficult, since it implies going against a strong working culture.

  7. 20. Genetics and Growth Regulation in Salmonella enterica

    Författare :Jessica M. Bergman; Diarmaid Hughes; Dan I. Andersson; Måns Ehrenberg; Stanley Maloy; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tufA; tufB; EF-Tu; ppGpp; Stringent response; RNase E; RNA turnover; Post-transcriptional regulation; rpoB; rpoS; Growth in stationary phase; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Mikrobiologi; Microbiology; Molekylär genetik; Molecular Genetics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. LÄS MER
