  1. 16. The role of progesterone in the regulation of ciliary activity in the fallopian tube

    Författare :Magdalena Nutu; Göteborgs universitet; []
    Nyckelord :progesterone; progesterone receptor; non-genomic progesterone receptor; ciliated cells; fallopian tube; gamete transport; ciliary activity; ciliary beat frequency; reproduction; fertility;

    Sammanfattning : The overall aim of this thesis was to investigate the distribution and regulation of membrane progesterone receptors (mPRs) that may be involved in regulating ciliary activity in the fallopian tube. The fallopian tube serves to transport the egg and spermatozoa to achieve fertilization. LÄS MER

  3. 17. District heating and cooling systems transition : Evaluation of current challenges and future possibilities

    Författare :Marwan Abugabbara; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-domain modelling; Modelica; Heat pumps; 5GDHC; BLTN; Validation;

    Sammanfattning : District heating and cooling systems offer a cost-effective and secure supply of heating and cooling to connected buildings. They are widely recognised as a key solution to decarbonise the building sector due to their high potential of integrating renewable energy sources. LÄS MER

    Författare :Zaka Ullah Sheikh; Håkan Håkan Johansson; Oscar Gustafsson; Jeffery Coleman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Complexity reduction is one of the major issues in today’s digital system designfor many obvious reasons, e.g., reduction in area, reduced power consumption,and high throughput. LÄS MER

  7. 20. Text Representations and Explainability for Political Science Applications

    Författare :Denitsa Saynova; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political Science; Explainability; NLP; Representation;

    Sammanfattning : This work explores the utility of natural language processing approaches for the study of political behavior by examining two main aspects - representation and explainability. We investigate how current representation approaches capture politically relevant signals in a proportional representation system. LÄS MER
