1. 1. Vintage models of spatial structural change

   Författare :Lars Westin; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; adiabatic approximation; dynamics; input-output; interregional computable general equilibrium; slaving principle; spatial models; spatial linear expenditure system; spatial price equilibrium; transportation networks; vintage function;

   Sammanfattning : In the study a class of multisector network models, suitable for simulation of the interaction between production, demand, trade, and infrastructure, is presented. A characteristic feature of the class is a vintage model of the production system. LÄS MER

3. 2. Effects of Flow Structure on Particle Separation in Dissolved Air Flotation

   Författare :Måns Lundh; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasma; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp; Gases; fluid dynamics; plasmas; Gaser; fluiddynamik; Teknik; Technological sciences; modelling; retention time distribution; acoustic doppler velocimeter; flow structure; separation; water treatment; wastewater treatment;

   Sammanfattning : Dissolved Air Flotation (DAF) is a separation process in water and wastewater treatment. The removal function is based on reducing the density of the particle by producing aggregates of the particles and added micro-bubbles of air, thus lifting the aggregates to the water surface, where they can be removed as sludge.

4. 3. Den sociala differentieringens retorik och gestaltning : Kritiska perspektiv på funktionalistisk förorts- och bostadsplanering i Stockholm från 1900-talets mitt

   Författare :Christian Björk; Hans Hayden; Helena Kåberg; Martin Rörby; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Swedish welfare state; Stockholm; Functionalism; Suburban planning; City planning; Urban Policy; Differentiation; Segregation; Spatial separation; Housing planning; Interior decoration; Upper middle-class; Private sphere; Public sphere; Gender coded rooms; Consumption; konstvetenskap; Art History;

   Sammanfattning : In this thesis, I analys suburb- and housing planning and interior decoration carried out primarily in Stockholm between the 1930s and the 1950s. Functionalism, the overall concept of the period, has perhaps been interpreted in terms of ideological concepts, interpreted as "democratic" and as a progressive dividing line between the past and the future.

5. 4. Acoustic Forces in Cytometry and Biomedical Applications: Multidimensional Acoustophoresis

   Författare :Carl Grenvall; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustophoresis; Microfluidics; Ultrasound; Multinode; Cell Sorting; Particle Positioning; Cytometry; Lab-on-a-Chip; µTAS; Binary Separation; Acoustic Barriers; Acoustic Particle Manipulation; Acoustic Standing Waves; Blood Separation; Milk Analysis;

   Sammanfattning : Over the last decades the ongoing work in the fields of Lab-on-a-Chip and Micro-Total-Analysis-Systems has led to the discovery of new or improved ways to handle and analyse small volumes of biofluids and complex biosuspensions. The benefits of working on the microscale include: miniaturization of the analysis systems with less need for large sample volumes; temporal and spatial control of suspended particle/cell positions; low volume sheath flow lamination or mixing; novel separation techniques by using forces inherent to the microscale domain; precise regulation of sample temperatures and rapid analysis with less volumes needed to be processed.

7. 5. Rummet och rätten Tingshus som föreställning, byggnad och rum i användning 1734-1970

   Sammanfattning : SPACE AND COURT Swedish rural district court-houses 1734-1970; conceived, materialized and used Abstract Although the court of justice is a fundamental institution of our society, the socio-spatial conditions and past of the Swedish district court have rarely been objects of academic research. The aim of this thesis is to examine the design of rural district court-houses from the period of 1734-1970, starting out from the often-assumed causal relation between function and form. LÄS MER
