1. 1. Capacity utilisation in short sea shipping

   Författare :Linda Styhre; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sailing schedule; unutilised capacity; improvement measures; Liner short sea shipping; vessel capacity utilisation; route characteristics; strategies;

   Sammanfattning : Shipping is a capital-intensive industry and is characterised by high fixed costs and economies of scale. Trade imbalances and demand variations, market fluctuations and customer demands for high frequency create a situation where shipping companies tend to operate with a high level of unutilised vessel capacity.

3. 2. Wear characteristics of materials for artificial hip joints

   Författare :Mohammed Seyed Hoseini Nazari; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HDPE; UHMWPE; Coating; Tribology; Pin-on-disc; Y-irradiation; Vitamin E; Wear; Implant; Artificial hip joint;

   Sammanfattning : Total hip prostheses have succeeded in significantly improving the quality of life of millions of patients worldwide. Ultra high molecular weight polyethylene (UHMWPE) has been widely and successfully used as a bearing material in orthopaedic prostheses since the 1960s. LÄS MER

4. 3. Photoluminescence Characteristics of III-Nitride Quantum Dots and Films

   Författare :Martin Eriksson; Per-Olof Holtz; Peder Bergman; Fredrik Karlsson; Volodymyr Khranovskyy; Yasuhiko Arakawa; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : III-Nitride semiconductors are very promising in both electronics and optical devices. The ability of the III-Nitride semiconductors as light emitters to span the electromagnetic spectrum from deep ultraviolet light, through the entire visible region, and into the infrared part of the spectrum, is a very important feature, making this material very important in the field of light emitting devices.

5. 4. The Effect of Ladle Treatment on Steel Cleanness in Tool Steels

   Författare :Karin Steneholm; Pär Jönsson; Guozhu Ye; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxygen activity; inclusion characteristics; vacuum degassing; desulphurization; slag; ladle; hydrogen; nitrogen; deslagging; Teknisk materialvetenskap; Materials Science and Engineering;

   Sammanfattning : The aim of the present work was to get an overview of the steel cleanness in tool steel. Plant trial studies of three steel grades were done with different focuses.Firstly the change of the inclusion characteristics during the vacuum degassing in the ladle was looked upon. LÄS MER
