The forest industry is one of Sweden’s most important business areas. As the use of paper is declining the need for this sector to find other alternatives is increasing. An attractive option to meet this demand is the establishment of forest biorefineries. However, economically suitable pretreatment methods for woody biomass, which minimize degradation of the structural carbohydrates and allow the
Hydrogels are a hydrophilic network of polymers (usually cross-linked polysaccharides) that are natural or synthetic. Applications of hydrogels are many in the biomedical field. Because of the high water absorption (10 to 200 grams of water per gram of hydrogel), hydrogels have a high degree of flexibility similar to natural human tissue. Human cells can be incorporated into the hydrogel, which in
Galactoglucomannans (GGM) can be used as a precursor for the production of surfactants, plastics, hydrogels etc. However, separation of galactoglucomannan (GGM) from lignin and lignin-carbohydrate-complexes using membrane filtration is difficult. Precipitation of GGM with anti-solvents is an approach that has been previously studied. A membrane filtration step prior to precipitation is economicall
Morphology represents a hitherto unexploited source of specificity in microfluidic particle separation and may serve as the basis for label-free particle fractionation. There is a wealth of morphological changes in blood cells due to a wide range of clinical conditions, diseases, medication and other factors. Also, blood-borne parasites differ in morphology from blood cells. We present the use of
We have all experienced how a telephone conversation can be more challenging than speaking face to face. Understanding the intended meaning of a speaker‘s words requires forming an impression of the current mental state of the speaker, including her beliefs, intentions, and emotional state (Sperber & Wilson, 1995). Facial expressions are an important source of this information. In this study,
In this work we present theoretical modeling and additional experiments to characterize noncontact acoustic trapping in a small glass capillary. We provide numerical 3D-simulations that captures several key features of the experiment.
This paper reports simultaneous detection of ultra violet (UV) absorbance and native UV-excited fluorescence in an electrophoresis microchip using UV transparent integrated waveguides. Absorbance detection enables detection of a wide range of analytes. When exposed to UV light, some compounds also exhibit native fluorescence, which is here detected simultaneously. Calibration curves were measured
Membrane-bound water channels known as aquaporins (AQPs) facilitate water transport across biological membranes along osmotic gradients. Since all living cells depend on their ability to maintain water homeostasis, this must be tightly regulated. In eukaryotes, this is achieved by gating, which involves a conformational change of the protein, thereby physically blocking water transport, or by traf
This study explores the possibility that the delayed hypoperfusion observed after an ischemic insult might be due to vasoconstriction induced by the release of noradrenaline from nerves originating in the locus ceruleus. Bilateral 6-hydroxydopamine lesions of the ascending bundles from the locus ceruleus were carried out in the caudal mesencephalon of rats. Local CBF was measured with an autoradio
Normal sexual differentiation requires complex molecular events to take place in a precise order, and even though much knowledge has been gained in recent decades, further research is still needed to understand the pathogenesis of different disorders of sexual differentiation. For the clinician who is confronted with a child with sexual ambiguity, it is most important not to guess the sex but to i
This panel is devoted to an exploration of multimodal, visual staging of meaning in the Middle East and its transnational interconnectedness. Presentations will discuss examples of visual inventiveness in different and multimodal medial contexts, varying both in terms of motivations, positions of power and visual strategies employed. The panel invites reflection on how the study of current visual
This paper presents an adaptive video encoder that can be used to compare the behavior of different adaptation strategies using multiple actuators to steer the encoder towards a global goal, composed of multiple conflicting objectives. A video camera produces frames that the encoder manipulates with the objective of matching some space requirement to fit a given communication channel. A second obj
Self-adaptive software systems monitor their operation and adapt when their requirements fail due to unexpected phenomena in their environment. This paper examines the case where the environment changes dynamically over time and the chosen adaptation has to take into account such changes. In control theory, this type of adaptation is known as Model Predictive Control and comes with a well-develope
