2. 11. Grouting of Fractured Rock with Silica Sol; Grouting design based on penetration length

   Author : Johan Funehag; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grouting; hydraulic test; sand column; propagation; penetration length; pipe flow; aperture; transmissivity; colloidal silica; silica sol; rheology; gelling liquids; field study;

   Abstract : ABSTRACTRecent grouting projects in Sweden have concentrated on the grout itself. The only grout normally used in Sweden is cement-based. During the past 10 years, the acceptable flow of water into tunnels has been reduced significantly. The current requirements mean that an average fracture aperture of around 0. READ MORE

4. 12. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

   Author : Tord Isaksson; Avdelningen för Konstruktionsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

   Abstract : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.

5. 13. Exposure, telomere length, and cancer risk

   Author : Huiqi Li; Avdelningen för arbets- och miljömedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; exposure; telomere; methylation; chromosomal aberration; cancer risk; rubber fumes; arsenic; welding fumes; diesel exhaust; particulate matter;

   Abstract : Telomeres are tandem repeats of TTAGGG at the end of eukaryotic chromosomes. Telomeres play a key role in chromosome stability and regulation of the cellular lifespan. Telomeres are shortened during cell division, and probably, by not yet well characterised factors in the environment. READ MORE

6. 14. Particle Measurements Using Fluctuations in the Regular Transmittance of Light Through a Particle Dispersion : Concentration and Particles size - Theory, Measurement Principles and Applications for Pulp and Paper Production

   Author : Staffan Rydefalk; Lars Mattsson; John Gregory; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Particle concentration; Particle size; Cylindrical particles; Large particles; Cellulose fibres; Wood pulp fibres; Suspensions; Particle length; Particle length distribution; Particle width; Manufacturing engineering; Produktionsteknik;

   Abstract : The regular transmittance of light or similar radiation through a flowing suspension of particles fluctuates because of the random occurrence of particles in the beam.In the work presented here, a theory for this fluctuating behaviour with the emphasison dispersions of mm-length slender cylindrical particles having circular crosssections is given.

7. 15. Time and general practice consultations : aspects of length, attendance and quality

   Author : Sven-Olof Andersson; Bengt Mattsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; General practice; primary health care; consultation; time; doctor-patient relation; satisfaction; primary care nurse; frequent attender;

   Abstract : The consultation is the GP’s form of work. How long a consultation should be, and what short/long consultations imply with regard to the satisfaction of patient and doctor has been much debated. The aim of this thesis was to study consultations with regard to content and time consumption in a short term and long term perspective. READ MORE
