1. 6. Relationship between chemical structure and airway sensitizing potential for organic acid anhydrides : an animal model

   Författare :Xing-Dong Zhang; Avdelningen för arbets- och miljömedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensitization; immunization; predictive testing; low-molecular-weight chemicals; chemical respiratory allergy; hypersensitivity; rats; guinea pigs; structure-activity-relationship; occupational asthma; organic acid anhydrides; IgG1; IgE; Occupational health; industrial medicine; Yrkesmedicin; arbetsmiljömedicin;

   Sammanfattning : Oranic acid anhydrides (OAAs) are important reactive, low-molecular-weight industrial chemicals which induce allergic rhinitis and asthma in exposed subjects. Specific IgE has been demonstrated in a large proportion of OAA-exposed workers. LÄS MER

3. 7. Mechanistic-Empirical Modelling of Flexible Pavement Performance : Verifications Using APT Measurements

   Författare :Abubeker W. Ahmed; Sigurdur Erlingsson; Hervè Di Benedetto; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance; Deformation; Model not math ; Rutting wheel ; Viscoelasticity; Elasticity; Axle load; Flexible pavement; Laboratory not an organization ; Test; Thesis; Heavy vehicle simulator; Wheel tracking test; 32 Road: Pavement design; 32 Road: Pavement design; Transportvetenskap; Civil and Architectural Engineering;

   Sammanfattning : Mechanistic-Empirical  (M-E)  pavement  design  procedures  are  composed  of  a  reliable  response model to estimate the state of stress in the pavement and distress models in order to predict the different types of pavement distresses due to the prevailing traffic and environmental conditions. One of the main objectives of this study was to develop a response model based on multilayer elastic  theory   (MLET)  with  improved  computational  performance  by   optimizing  the   time consuming parts of the MLET processes.

4. 8. Hydro-mechanical properties of a water unsaturated sodium bentonite. Laboratory study and theoretical interpretation

   Författare :Ann Dueck; Institutioner vid LTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Anläggningsteknik; Material technology; Construction technology; materialteknik;

   Sammanfattning : Highly compacted bentonite has been proposed as the buffer material in the Swedish concept for the disposal of nuclear waste. To increase the knowledge of the hydro-mechanical behaviour of unsaturated swelling bentonite a series of laboratory experiments was carried out. LÄS MER

5. 9. Scattering of elastic waves by an anisotropic sphere

   Författare :Ata Jafarzadeh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sphere; T matrix; Effective wave number; Distribution of inclusions; Phase velocity.; Anisotropy; Attenuation; Scattering;

   Sammanfattning : Scattering of a plane wave by a single spherical obstacle is the archetype of many scattering problems in physics and geophysics. Spherical objects can provide a good approximation for many real objects, and the analytic formulation for a single sphere can be used to investigate wave propagation in more complicated structures like particle composites or grainy materials, which may have application in non-destructive testing, material characterization, medical ultrasound, etc. LÄS MER

7. 10. Battery Health Estimation in Electric Vehicles

   Författare :Verena Klass; Göran Lindbergh; Mårten Behm; Anna Stefanopoulou; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; state-of-health; electric vehicle; support vector machine; resistance; capacity; Chemical Engineering; Kemiteknik;

   Sammanfattning : For the broad commercial success of electric vehicles (EVs), it is essential to deeply understand how batteries behave in this challenging application. This thesis has therefore been focused on studying automotive lithium-ion batteries in respect of their performance under EV operation. LÄS MER
