1. 16. MEMS Interfaces for Bioanalysis Systems

   Författare :Thomas Frisk; Göran Stemme; Andreas Hierlemann; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microfluidic interfacing; microfluidics; µTAS; sample transfer; biosensor; electronic nose; surface tension; quartz crystal microbalance; QCM; narcotics detection; Electronic measurement and instrumentation; Elektronisk mät- och apparatteknik;

   Sammanfattning : This thesis deals with various aspects of using open microfluidic interfaces. Three specific areas of application are studied. The first is air-to-liquid interfacing in biosensors with possibilities for component inte­gration. A micromachined interface for airborne sample-to-liquid and droplet-to-liquid adsorption is discussed. LÄS MER

3. 17. Wood hydrolysate Barriers

   Författare :Anas Ibn Yaich; Ulrica Edlund; Ann-Christine Albertsson; Margaretha. Söderqvist-Lindblad; Inger Odnevall-Wallinder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood hydrolysate; xylan; hemicellulose; layered silicates; oxygen barrier; packaging; film; coaing; birch.;

   Sammanfattning : Wood hemicellulose is an abundant but fairly unexploited renewable feedstock. Recent studies have shown that hemicelluloses have a large potential for use in the food packaging industry as a sustainable alternative to the conventional oxygen-barrier materials used today.

4. 18. Prediction and experimental validation of dynamic soil-structure interaction of an end-bearing pile foundation in soft clay

   Författare :Freddie Theland; Jean-Marc Battini; Amir Kaynia; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic soil-structure interaction; Pile group; End-bearing piles; Dynamic impedance; Environmental vibration; Experimental validation; Dynamisk jord-struktur-interaktion; Pålgrupp; Spetsbärande pålar; Dynamisk impedans; Omgivningsvibrationer; Experimentell validering; Structural Engineering and Bridges; Bro- och stålbyggnad;

   Sammanfattning : In the built environment, human activities such as railway and road traffic, constructionworks or industrial manufacturing can give rise to ground borne vibrations. Such vibrations become a concern in urban areas as they can cause human discomfort or disruption of vibration sensitive equipment in buildings. LÄS MER

5. 19. Shards of Iron Age Communications. A ceramological study of internal structures and external contacts in the Gudme-Lundeborg Area, Funen during the Late Roman Iron Age

   Författare :Ole Stilborg; Arkeologi; []
   Nyckelord :HUMANIORA; HUMANITIES; local; Funen; Gudme-Lundeborg Area; trading site; cemetery; settlement; Late Roman Iron Age; material systems; Things; communication; Pottery; ceramology; import; center; Archaeology; Arkeologi;

   Sammanfattning : The objective of ceramology is to describe pottery craft traditions; the potters, their production, social organisation and the use of the products. Through this the human actions surrounding the pottery are studied. LÄS MER

7. 20. Modelling of thin and imperfect interfaces : Tools and preliminary study

   Författare :Mathieu Gaborit; Peter Göransson; Olivier Dazel; Émeline Sadoulet-Reboul; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin layers; numerical methods; FEM; poroelastic materials; couches fines; méthodes numériques; MEF; matériaux po- roélastiques; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : For quite some time, the strive for more efficient acoustic absorbers keepsincreasing, driven by a number of psycho-physiological studies on health re-lated dangers of noise exposure. As the global wealth increases and with itthe global expectation of quieter living and working environments, manifestedin both politics and research, an important market for sound absorbing andnoise control systems develops in all industrialised countries.
