Several valuable substances are released from wood during the production of thermomechanical pulp. These substances can be isolated and purified for use as value-added chemicals. The hemicellulose galactoglucomannan (GGM) has attracted a great deal of interest because of its possible applications as an oxygen barrier film in packaging materials, as a hydrogel in biomedical products and as an emuls
The limited thermal stability of polyhydroxyalkanoates (PHAs) hinders their wide applicability, and methods to improve the processability of these biopolyesters are needed for efficient processing, e.g. by melt extrusion. In the present study we have shown by isothermal gravimetry, dynamic rheology and molecular weight analysis that the thermal stability of the PHAs at the processing temperature c
As the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent. A research-proven approach to achieve ULP consumption is to aggressively lower the supply voltage (VDD) below or in the vicinity of the transistor threshold voltage (Vth) and operate the transistors in the subthreshold (sub-Vth) region. Operating below or near the threshold voltage, i.eAs the Internet of Things (IoT) era emerges the need for ultra-low power (ULP) devices is becoming more eminent.

The reaction between the SO5– radical and MnII has been proposed to be the most important process for regeneration of MnIII in the MnIII/II-catalysed autoxidation of SIV in acidic aqueous solution. In the present study, the second-order rate constant for this reaction has been determined at pH 3. 0 and 10 mmol dm–3 ionic strength by use of pulse radiolysis. The study was performed in the presence
Objectives: To describe the process and outcomes of using a new evidence base to develop scientific guidelines that specify the type and minimum dose of exercise necessary to improve fitness and cardiometabolic health in adults with spinal cord injury (SCI). Setting: International. Methods: Using Appraisal of Guidelines, Research and Evaluation (AGREE) II reporting criteria, steps included (a) det
UHT direct steam injection and steam infusion are widely used; however there is no comparison of their impact on milk components. This study evaluates the structural changes at different steps during the UHT processing of whole milk in a full-scale UHT plant by transmission electron microscopy (TEM) and particle size measurements, and follows the enzymatic activity. The results of structural anal
Due to its real advantages in terms of spatial resolution, the MRI technique has been chosen in order to study the internal moisture in 2.5 mm thick industrial pulp samples. A spin-echo sequence with very short echo-time (TE= 2 ms) has been designed to measure moisture content inside highly hygroscopic materials and was able to detect moisture even at very low moisture content (6%). In order to en
Microcrystalline cellulose (10 g/L Avicel) was hydrolysed by two major cellulases, cellobiohydrolase I (CBH I) and endoglucanase II (EG II), of Trichoderma reesei. Two types of experiments were performed, and in both cases the enzymes were added alone and together, in equimolar mixtures. In time course studies the reaction time was varied between 3 min and 48 h at constant temperature (40degreesC)
Popular Abstract in Swedish I den första avhandlingen på svenska om den finlandssvenske estetikern, filosofen och författaren Hans Ruin (1891–1980) förenas ett intresse för det litterära uttrycket med ett intresse för människan bakom orden. Litteraturen som mänskligt dokument, som spåret efter en människa, och dess funktion som överbringare av erfarenheter och insikter står i centrum för framställThe first dissertation in Swedish of the Finno-Swedish aesthetician, philosopher and writer Hans Ruin (1891–1980) combines an interest in the literary expression with an interest in the man behind the words. Literature as a human document, as the footprint of a human being, and its function as a bearer of experiences and insights is at the heart of the characterisation. The title of this dissertat
In a finite world, developing a sustainable society requires both a more sustainable management of resources and a more sustainable management of human beings.Therefore deep understanding of processes underlying systems of production and consumption is needed. The question that is being asked in this chapter is whether neoclassical economics can provide solid ground to further advance the economic
This study is analyzing the foreign relations of three major Iraqi communities, namely the Shia Arabs, the Kurds and Sunni Arabs. In order to properly characterize these communities’ external relations with neighboring countries, some of their foreign policy choices are examined at national and regional contexts. The issue of unresolved territorial disputes among the groups and ongoing security pr

Rapport_Lönepremier för utbildning2.indd Lönepremier för utbildning – Utveckling under 2000-talet 2 Sammanfattning Denna rapport granskar lönepremien för högskoleutbildning perioden 2001–2020. Högskolepremien har minskat och är lägre nu än den var i början av 2000-talet. Framför allt är utvecklingen negativ inom privat och statlig sektor. Högskole- premien ökar något de senaste åren, men det är

This essay has been written by two students attending the Bachelor of Political Science program at the department of Political Science at Lund University. The study aims to examine how theories of policy change explains the decision to extend voting rights to women in Sweden (universal and equal voting rights, 1918) and in the US (the 19th amendment to the constitution, 1920). By applying two theo
