In the present paper we give a general two-dimensional formalism for scattering in a multilayered medium with a finite inhomogeneity present. The formalism is based on the T matrix method, introduced by Waterman [J. Acoust. Soc. Am. 45, 1417 (1969)]. The formalism is developed in detail for the geometries consisting of one layer with an obstacle situated either inside or below the layer. More gene
This licentiate thesis concerns advanced digital product catalogues, with the main focus on product presentation. A computer based digital product catalogue opens new possibilities for advanced product presentation and integration into the existing compute environment. Several new possibilities for product presentation become available. By use of photorealistic rendering techniques, images showing
In the last decade or so an increasing number of researchers in Scandinavia have become interested in the research field of contentious politics studies (CPS). The result has been a growing number of publications focusing on political contention. We have now reached the point where international research networks are being set up. Several interesting workshops and book projects are underway unders
This paper develops the foundations and the implications of the mechanisms proposed as possible triggers for the demographic transition and the process of socio-economic development. In particular it examines the role played by gender equality and its significance for the understanding of the development process which allowed economies to move out of a long period of stagnation into a state of sus
Objectives: Skeletal muscle performance is determined by muscle temperature. This paperpresents a review of the research literature to contribute to a better understanding of thephysiological mechanisms of muscle fatigue and performance in cold exposure and in repetitiveor sustained physical exertion in terms of isometric maximal force production,electromyographic activities, and gait ground react
The cysteinyl-leukotrienes (cysLTs: LTC4, LTD4 and LTE4) have an important pathophysiological role in asthma. They are not only extremely potent bronchoconstrictors, but are also involved in the central mechanisms of the asthmatic inflammation and the subsequent remodelling of the airways. Allergen-induced bronchoconstriction as well as spontaneous exacerbations of asthma are associated with incre
This work concerns experimental and numerical studies of pressure drop and heat transfer for turbulent flow inside a U-duct and in particular the bend part. Such duct geometries can be found in many engineering applications where cooling air extracts heat from hot internal walls of the duct, e.g., passage cooling inside gas turbine blades. The details of the duct geometry were as follows: the cros
BACKGROUND: Hormone-sensitive lipase (HSL) is expressed predominantly in adipose tissue, where it plays an important role in catecholamine-stimulated hydrolysis of stored tri- and diglycerides, thus mobilizing fatty acids. HSL exhibits broad substrate specificity and besides acylglycerides it hydrolyzes cholesteryl esters, retinyl esters and lipoidal esters. Despite its role in fatty acid mobiliza
Popular Abstract in Swedish En burk målarfärg som har lämnats bortglömd, en senapsflaska som länge har stått upprätt i ett kylskåp eller ett nyinköpt filmjölkspaket som precis ska öppnas. Det finns många vardagliga situationer där vi stöter på separation av fasta partiklar från vätskan i så kallade suspensioner. Separationsprocessen kallas sedimentering och är den tillämpning som genomgående motivA consistent theme throughout this thesis is quasilinear partial differential equations (PDEs) appearing in one-dimensional models of sedimentation for solid-liquid separation of suspensions. We mainly focus on continuous sedimentation in so-called clarifier-thickeners (CTs), which are found in mineral processing and wastewater treatment. In addition to complications with shocks and non-unique sol
An interpretation is given of the threshold photoelectron spectrum of Ar between the P-3 and D-1 double-ionization thresholds. In this region the observed spectrum is less cluttered than below the P-3 thresholds and the interpretation is more straightforward. One of the characteristic features of the spectrum is the excitation to Rydberg orbitals with high angular momentum l in agreement with the
The present study reports the reliability of the Swedish versions of Brief COPE (Carver, 1997) and LOT-R (Scheir, Carver & Bridges, 1994). Brief COPE consists of 28 items measuring 14 different coping strategies. LOT-R consists of sex items assessing generalized optimism. Altogether 332 undergraduate students (236 women and 93 men) participated in the study. The reliability coefficients indica
This study analyses the development of natural philosophy in Scandinavia in the 16th and 17th century. Rather than dealing with individual natural philosophers and ideas, it evolves around groups of natural philsophers - the Bartholin family and the former assistants of Tycho Brahe in Denmark, the Rudbeck family in Sweden. The study of nature is put into a cultural, religious, social, and politica
Poor communication between surgical and anesthesia unit personnel may jeopardize patient safety. Review reports from a national survey on patient safety performed at 17 units 2011-2013 were analyzed in order to identify strategies to reduce risks related to the interaction between surgery and anesthesia. The reports were reviewed in this study by an independent group in order to extract findings r
