1. 36. Spectroscopic and Microscopic X-ray Fluorescence Analysis for Environmental and Industrial Applications

   Författare :Siwen An; Börje Norlin; Göran Thungström; David Krapohl; Yuying Huang; Mittuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Heavy metals are well-known environmental pollutants due to its potential impact on associated ecosystems and human health. Thus, it is important to monitor the levels of heavy metals in the environment. X-ray fluorescence (XRF) analysis is a powerful and effective screening tool in measuring the concentration of multi-elements simultaneously. LÄS MER

3. 37. Characterization and engineering of carbohydrate-active enzymes for biotechnological applications

   Författare :Noor Hassan; Christina Divne; Eva Nordberg Karlsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; se conversion; galacto-oligosaccharides; thermostability; propeptide; Bioteknologi; Biotechnology;

   Sammanfattning : Extremozymes are enzymes produced by microorganisms that live in extreme habitats. Due to their higher stability, extremozymes is attracting interest as biocatalysts in various industrial processes. In this context, carbohydrate-active extremozymes can be used in various processes relevant to the paper, food and feed industry. LÄS MER

4. 38. Modelling of IC-Engine Intake Noise

   Författare :Magnus Knutsson; Mats Åbom; Yves Auregán; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IC-engine; intake noise; gas dynamics; linear source data; frequency domain; 2-port; losses; air cleaner unit; filter paper; flow; FEM; BEM; charge air cooler; narrow tube; Acoustics; Akustik;

   Sammanfattning : Shorter product development cycles, densely packed engine compartments and intensified noiselegislation increase the need for accurate predictions of IC-engine air intake noise at earlystages. The urgent focus on the increasing CO2 emissions and the efficiency of IC-engines, aswell as new techniques such as homogeneous charge compression ignition (HCCI) mightworsen the noise situation.

5. 39. Safety Reviews of Technical System Modifications in the Nuclear Industry

   Författare :Thomas Falk; Sven-Ove Hansson; Teemu Reiman; KTH; []
   Nyckelord :safety; safety review; nuclear; nuclear power plant; process; process improvement; action research; experience feedback;

   Sammanfattning : The function of safety reviews (here understood as expert judgements on proposals for design modifications and redesign of technical systems in commercial Nuclear Power Plants, supported by formalised safety review processes) plays a fundamental role for safety in nuclear installations. The primary aims of the presented case studies includes: critically examining and identifying the main areas for improvement of the existing technical safety review process as it is conducted at a Swedish nuclear power plant, developing a new process, and evaluating whether any improvements were accomplished.

7. 40. Structural Design of Laser-Welded Sandwich Panels for Marine Applications

   Författare :Hans Kolsters; KTH; []
   Nyckelord :Sandwich; Laser welding; Web; Core; Stiffness; Elastic Buckling; Ultimate strength; Finite element analysis; Mechanical testing; Optimisation.;

   Sammanfattning : In shipbuilding the replacement of stiffened platestructures by laser-welded sandwich panels offers considerableadvantages for production as well as vessel operation. In viewof reduced weight and space requirements an area of particularinterest is the incorporation of an adhesively bonded core bywhich the stiffness and strength can be substantiallyincreased, and thermal-acoustic insulation can be integrated.
