1. 1. Orsaker till fel i byggandet: en studie om felorsaker, felkonsekvenser, samt hinder för inlärning i byggprojekt

   Författare :Per-Erik Josephson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; consequences of defects; causes of defects; organisational behaviour; organisational learning; building project; quality; temporary organisations; defects; costs of defects;

   Sammanfattning : One means of increasing the effectiveness of building is minimisation of the numbers of de-fects and their consequences. In order to accomplish this, it is necessary to have knowledge of why defects occur, of their consequences, and of how to learn from errors. LÄS MER

3. 2. Evolution of artificial defects during shape rolling

   Författare :Mirjana Filipovic; Stefan Jonsson; Per-Olov Perä; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire rod rolling; artificial defects; defect evolution; surface cracks; porosity; FEM; high speed steel; stainless steel; Other materials science; Övrig teknisk materialvetenskap; Initiering och utveckling av defekter under spårvalsning;

   Sammanfattning : Very often defects are present in rolled products. For wire rods, defects are very deleterious since the wire rods are generally used directly in various applications. For this reason, the market nowadays requires wire rods to be completely defect-free. Any wire with defects must be rejected as scrap which is very costly for the production mill. LÄS MER

4. 3. Reducing water damage by using a holistic approach to costs, occurrence and solutions in buildings

   Författare :Christian Mattsson; Avdelningen för Installations- och klimatiseringslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water damage; building defects; Tap water; Costs; Sewage; Heating; Leakage; Vattenskador: byggnader; byggnadsdefekt; kostnader; avlopp; värmesystem; läckage; tappvatten;

   Sammanfattning : A large amount of water damage cases and resources are annually reported and spent on water damage in Sweden from cases occurring in buildings from building services such as tap water-, sewage, heating systems, household appliances such as refrigerators, freezers and dishwashers and inadequate waterproof membranes in wet rooms. These water damage cases in buildings cause several problems in the built environment regarding economic, environmental, and social aspects of sustainability such as unhealthy indoor environments due to higher levels of moisture, mold growth, and redundant usage of building materials and resources in reparations and renovations of water damaged constructions, immense amounts of monetary resources spent annually by both residents, building owners and insurance companies to restore the buildings to their designed purpose.

5. 4. Removal and Replacement of Ribosomal Proteins : Effects on Bacterial Fitness and Ribosome Function

   Författare :Christina Tobin; Dan I. Andersson; Richard Buckingham; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ribosome; protein synthesis; ribosomal proteins; translation initiation; ribosome biogenesis; fitness costs; compensatory evolution; horizontal gene transfer; Microbiology; Mikrobiologi; Biochemistry; Biokemi; Mikrobiologi; Microbiology;

   Sammanfattning : Protein synthesis is a complex process performed by sophisticated cellular particles known as ribosomes. Although RNA constitutes the major structural and functional component, ribosomes from all kingdoms contain an extensive array of proteins with largely undefined functional roles. LÄS MER

7. 5. Macro-Geometric Defects, A numerical and experimental study of springback and surface defects

   Författare :Alf Andersson; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation; Sheet-metal forming; Finite element analysis; Information exchange; Springback; Surface defects; Drawbead; Process analyse; Optimisation; materialteknik; Materiallära; Material technology;

   Sammanfattning : Today, shortened lead-times in the automotive industry have dramatically increased the need for more efficient development methods at every stage of the process development chain. In order to decrease the long lead-time for producing a forming tool, sheet-metal-forming simulation was introduced. LÄS MER
