1. 1. Mechanical Properties of Tailings : Basic Description of a Tailings Material from Sweden

   Författare :Riaz Bhanbhro; Peter Viklander; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

   Sammanfattning : Tailings dams are constructed to store waste material from mining industry and usually these dams are raised with time depending upon production rate. Tailings material is sometimes used in construction of tailings dams. LÄS MER

3. 2. Chitin nanofibers, networks and composites : Preparation, structure and mechanical properties

   Sammanfattning : Chitin is an important reinforcing component in load-bearing structures in many organisms such as insects and crustaceans (i.e. shrimps, lobsters, crabs etc.). LÄS MER

4. 3. Affective Surface Engineering for Product Design

   Författare :Martin Bergman; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; semantics; Design research; total appearance; soft metrology; surface roughness; technical functions; core values; product interaction; kansei engineering; emotional functions; hard metrology; sensation and perception;

   Sammanfattning : Design research, sensation and perception, hard metrology, emotional functions, semantics, surface roughness, product interaction, core values, total appearance… the list of scientific phrases never ends. Yet, what do they mean and how shall we use it when we are communicating with the industry and our end users? Is it possible to link the product experience to process parameters, put a number onto it? When you can measure spoken needs or even better, implied needs, of a product, and relate that data to the production, it is possible do create advanced products with high interaction stimuli.

5. 4. Tactile Perception - Role of Physical Properties

   Författare :Lisa Skedung; Mark Rutland; Katrin Danerlöv; Sören Andersson; Ann Maria Cornell; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Finger Friction; Skin Friction; Paper Friction; Friction Coefficient; Piezoelectric Force Sensor; Skin Tribology; Biotribology; Soft Tribology; Surface Roughness; Profilometry; Coated Paper; Uncoated Paper; Printing Paper; Magazine Paper; Tactile Perception; Psychophysics; Multidimensional Scaling; Magnitude Estimation; Paper Coarseness; Thermal Conductivity; X-ray Photoelectron Spectroscopy.; Chemistry; Kemi;

   Sammanfattning : The aim of this thesis is to interconnect human tactile perception with various physical properties of materials. Tactile perception necessitates contact and relative motion between the skin and the surfaces of interest. LÄS MER

7. 5. Structural design and properties of hydrogel biomaterials

   Författare :Mikael Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Polyacrylic acid; Mechanical properties; Microfibrillated cellulose; Drug release; Chitosan; Biomaterials; Swelling; Hydrogels;

   Sammanfattning : Today a range of materials are used in medical applications; such materials are collectively denoted as biomaterials. A special class of biomaterials currently given much scientific interest is hydrogels. In particular a contemporary research topic is to create multicomponent materials in which synergetic effects are achieved. LÄS MER
