   Författare :Md Annaduzzaman; Prosun Bhattacharya; Mustafa Ersoz; Joydeep Dutta; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chitosan Biopolymer; Characterization; Biodegradable; Arsenic V ; Uranium VI ; Adsorption; Isotherm; Kinetic model; Chitosan; Biopolymer; Karakterisering; Bionedbrytbar; arsenik V ; uran VI ; Adsorption; Isoterm; Kinetisk modell; Land and Water Resources Engineering; Mark- och vattenteknik;

   Sammanfattning : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. LÄS MER

3. 2. Measurement of Self-Heating of Biomass Pellets using Isothermal Calorimetry

   Författare :Ida Larsson; Karin Granström; Anders Lönnermark; Per Blomqvist; Patrick van Hees; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal calorimetry; biomass pellets; wood pellets; self-heating; reactivity; screening test; isoterm kalorimetri; pellets; biomassa; självuppvärmning; reaktivitet; screeningtest; Miljö- och energisystem; Environmental and Energy Systems;

   Sammanfattning : Self-heating in storage facilities of biomass pellet can lead to spontaneous combustion. This has resulted in many fires over the years, causing both financial and environmental losses.In order to assess the risk for spontaneous combustion of biomass pellets during storage, it is important to know how prone the fuel is to self-heating, i.e. LÄS MER

4. 3. Carrot Juice Processing - Effects on Various Quality Aspects

   Författare :Charlotte Alklint; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modified atmosphere; shelf-life; accelerated storage; isothermal calorimetry; pressing; expression method; colour; dietary fibre; carotene; composition; carrot pomace; carrot juice; carrot pulp; acidification; Food and drink technology; Livsmedelsteknik;

   Sammanfattning : Carrots are a cold-weather crop well suited for cultivation in the south of Sweden. Carrots are generally rather inexpensive, with a market price below € 1 /kg (Sweden, 2003), whereas fresh carrot juice has a price of around € 5 /kg. LÄS MER

5. 4. Crack growth in single crystal gas turbine blade alloys under service-like conditions

   Författare :Frans Palmert; Johan Moverare; David Gustafsson; Mikael Segersäll; Philippa A.S. Reed; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Single crystal superalloy; TMF; Crack growth; Crystallographic crack growth; Aging; Hold time; Creep crack growth;

   Sammanfattning : This work concerns the fatigue crack growth behaviour of nickel base single crystal superalloys. The main industrial application of this class of materials is in gas turbine blades, where the ability to withstand severe mechanical loading in combination with high temperatures is required.
