4. 13. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

   Författare :Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

   Sammanfattning : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). LÄS MER

5. 14. Theoretical Modeling and Near-Infrared Spectroscopy Monitoring of Vial Lyophilization

   Författare :Mikael Brülls; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-situ; simulation; monitoring; spectral peak area analysis; near-infrared spectroscopy; lyophilization; moisture; sublimation; vial; mathematical model;

   Sammanfattning : The research documented in this thesis was directed towards lyophilization of pharmaceuticals in vials (vial lyophilization) and it was focused on the design and control of this process. Theoretical modeling has considerable potential to guide experimental studies, thereby decreasing development time and improving the possibilities to achieve an optimal and robust process design.

7. 15. Element cycling in forest soils -modelling the effects of a changing environment

   Författare :Charlotta Walse; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; soil moisture; decomposition; base cations; weathering; acidification; scenario analysis; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Element cycling and nutrient supply in forest ecosystems are of vital importance for short-term productivity and for longer-term land management in terms of nutrient leaching and CO2 fixation. This thesis includes a series of studies with the objective of modelling some aspects of the effect of acidification and climate change on element cycling and nutrient supply in forest soil. LÄS MER
