    Sammanfattning : The objective of this thesis was to advance understanding in the field of biolubrication, finding inspiration from the human synovial joints. This was addressed by investigating the association of key biolubricants and the resulting lubrication performance. LÄS MER

  4. 8. Surface modification of birch and acetylated birch wood by silicone nanofilaments

    Författare :Haiyan Yin; Magnus Wålinder; Agne Swerin; Andra Dédinaité; Jan Van den Bulcke; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acetylated wood; surface modification; superhydrophobicity; plastron; wetting; silicone nanofilaments; UV irradiation; mold resistance; blue stain.; Acetylerat trä; ytmodifiering; superhydrofobicitet; plastron; vätning; silikon-nanofilament; UV-bestrålning; mögelresistens; blånad.; Building Materials; Byggnadsmaterial;

    Sammanfattning : The increasing awareness of sustainability motivates the development of building materials from renewable resources. The requirements of wood-based products with improved durability, for example, enhanced liquid repellence and UV and biological resistance, are still a challenge. LÄS MER

  7. 10. Att hjälpa andra : gåvans, rättvisans och medkänslans aporier i frivilligarbete

    Författare :Hanna Bäckström; Linda Berg; Sara Edenheim; Helen Andersson; Lisa Folkmarson Käll; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; civil society; critical social work; empathy; ethics of care; feminist ethics; gifts; gift-giving; moral perception; poststructuralist ethics; solidarity; street-begging; voluntary social work; civilsamhälle; kritiskt socialt arbete; empati; omsorgsetik; feministisk etik; gåvor; moralisk perception; poststrukturalistisk etik; solidaritet; tiggeri; frivilligt socialt arbete; genusvetenskap; gender studies;

    Sammanfattning : The thesis addresses the issue of social work in Swedish civil society, focusing on the ambition and practice of helping others as an existential as well as a social, political and cultural phenomenon. The aim is to study the ambiguities and aporetic conflicts that imbue helping activities and the desire to help others, using ethnographic as well as philosophical method. LÄS MER
