   Författare :Ylva Edwards; Ulf Isacsson; Klaus-Werner Damm; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bitumen; asphalt; additives; wax in bitumen; polyphosphoric acid in bitumen; rheology; IR-spectroscopy; dynamic mechanic analysis DMA ; bending beam rheometer BBR ; literature study; low temperature physical hardening; highway materials; morphology; modified bitumens; temperature susceptibility; low temperature performance; ageing; microscopy; chromatography; Fourier transform infrared spectroscopy; force ductility; conventional binder tests; asphalt performance; tensile strain restrained specimen test TSRST ; Building engineering; Byggnadsteknik;

   Sammanfattning : This doctoral thesis consists of a literature review, presented in two papers, and another six papers describing experimental studies of the influence of different kinds of wax and polyphosporic acid on bitumen and asphalt concrete mixture properties. The literature review should give an extensive description of the field of knowledge concerning wax in bitumen. LÄS MER

4. 23. Longitudinal study of infants with high-grade vesicoureteral reflux

   Författare :Sofia Sjöström; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vesico-ureteral reflux; congenital; infant; kidney function tests; renal insufficiency; urinary tract infections; bladder; urodynamics; spontaneous resolution; multivariate analyses;

   Sammanfattning : Background: Infants with congenital high-grade vesicoureteral reflux (VUR) have been regarded as a special group amongst children with reflux, with their own characteristics concerning renal damage, gender, resolution rate and causative mechanism. A dysfunctional bladder has been suggested to be associated with the condition. LÄS MER

5. 24. Alternatives to pickling : preparation of carbon and low alloyed steel wire rod

   Författare :Peter Gillström; Magnus Jarl; Sven-Erik Lundberg; Tarras Wanheim; Örebro universitet; []
   Nyckelord :Mechanical descaling; shot blasting; pickling; steel wire rod; wear; drawing; Mechanical engineering; Maskinteknik; Maskinteknik; Mechanical Engineering;

   Sammanfattning : A well established method for scale removal on hot rolled wire rod is pickling. To avoid pollution problems, the wire rod can be mechanically descaled. By this method, the removed scale can be recirculated to the blast furnace. In batch pickling considerable energy is necessary; e. LÄS MER

7. 25. The Influence of Composition and Hot Processes on Heat Affected Zone and Weld Metal Behavior and Mechnacal Properties of Ti Grade 5 and Stainless Steel

   Författare :Esa Kivineva; KTH; []
   Nyckelord :Stainless steel; Duplex stainless steel; Titanium Grade 5; Ti-6Al-4V; Microstructure; Mecjhanical properties; Welding; Welding simulation;

   Sammanfattning : This thesis discusses on results of experiments carried outwith austenitic, duplex and super duplex stainless steels andTi-6Al-4V. In these it has been seen that the heat cycle duringwelding or weld simulation has a great effect on the propertiesof thematerials. LÄS MER
