1. 1. Airborne sound insulation of single and double plate constructions

   Författare :Ulrica Kernen; Gudni Jóhannesson; Waldemar Maysenhölder; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction engineering; : Airborne sound insulation; single plate; double plate; floating-floor; sound reduction index; sound transmission.; Byggnadsteknik; Building engineering; Byggnadsteknik;

   Sammanfattning : The sound insulation demands for dwellings and public building has increased over the years as the number of sound sources has grown. From the outside our homes are exposed to noise from cars, trains, airplanes, etc. Noise intrudes from our neighbours and their television and stereo equipments. LÄS MER

3. 2. From single-cell transcriptomics to single-molecule counting

   Författare :Saiful Islam; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : RNA-sequencing (RNA-seq) technology has been progressing so fast in the last few years and made it possible to perform transcriptome analysis at single-cell level that was even unimaginable a few years before. Nowadays, the importance of gene expression analysis at the single-cell level is increasingly appreciated for the study of complex heterogeneous tissue. LÄS MER

4. 3. Toxicometabolomics and biotransformation product screening in single zebrafish embryos

   Författare :Anton Ribbenstedt; Jonathan P. Benskin; Magnus Breitholtz; Elena Gorokhova; Emma Schymanski; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Non-target; REACH; Orbitrap; single embryo; zebrafish embryo; metabolism; high throughput; hydroxylation; glucuronidation; metabolite screening; phase I; phase II; pharmaceutical; structure elucidation; conjugation; propranolol; beta blocker; Non-targeted; toxicometabolomics; Orbitrap; single embryo; 3R; metabolomics; MoA; mode of action; zebrafish embryo; carbamazepine; biotransformation; Applied Environmental Science; tillämpad miljövetenskap;

   Sammanfattning : Over the last decade environmental agencies worldwide have escalated their work to phase out animal testing for the purposes of chemical regulation. Meanwhile the number of commercially available chemicals and the requirements for hazard assessments have both increased, creating a large need for substitution of traditional in vivo assays with in vitro tests.

5. 4. The shear plate dowel joint : Research on a novel connection for heavy timber structures

   Författare :Gustaf Larsson; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber connection; rubber foil; resilient bond line; single dowel; heavy timber structures;

   Sammanfattning : An increased use of wood can reduce the environmental footprint of the building sector. In order to improve the competitiveness of heavy timber structures, the thesis presents a novel type of timber connection with a high degree of prefabrication. LÄS MER

7. 5. Estimation of Thermal and Hydraulic Characteristics of Compact Brazed Plate Heat Exchangers

   Författare :Vijaya Sekhar Gullapalli; Institutionen för energivetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brazed plate heat exchangers; CFD; heat transfer; pressure drop; heat exchanger selection software; transcritical-CO2 calculations; heat exchanger rating; evaporation; condensation; refrigerant properties; discretized calculations;

   Sammanfattning : This thesis work presents various performance estimation methods of compact brazed plate heat exchangers (BPHE) operating in single phase, condenser, evaporator, cascaded and transcritical applications. Such methods play a vital role in development of heat exchanger selection software and during geometry parameter estimation in the new product development process. LÄS MER
