DIGITAL ANALYSIS OF CARDIAC ACOUSTIC SIGNALS IN CHILDREN Milad El-Segaier, MD Division of Paediatric Cardiology, Department of Paediatrics, Lund University Hospital, Lund, Sweden SUMMARY Despite tremendous development in cardiac imaging, use of the stethoscope and cardiac auscultation remains the primary diagnostic tool in evaluation of cardiac pathology. With the advent of miniaturized and po

Popular Abstract in Swedish Stroke (även kallat slaganfall) är den tredje vanligaste dödsorsaken efter hjärtsjukdom och cancer i stora delar av världen. Strokesjukdomen består av blodpropp (hjärninfarkt), blödning i hjärnan (intracerebral blödning) eller blödning i dess hinnor (subaraknoidal blödning). Stroke definieras enligt WHO som snabbt påkomna neurologiska symptom (t.ex. förlamning, talsvåriBackground: Stroke is a major cause of death and disability. Investigations of the epidemiological trends for stroke might result in better understanding of stroke pathogenesis and prevention. Methods: The trends of first-ever stroke incidence and survival over 3 time periods (1983-85, 1993-95 and 2001/2002) in Lund-Orup health care district were studied. The first 2 study periods were retrospect

The association behaviour of a number of glucitol amine gemini surfactants has been investigated by means of molecular dynamics and self-consistent-field calculations. We have shown that the titratable head group of the surfactant is responsible for a micelle-to-membrane transition when changing the pH. Furthermore, the association structure of this group of surfactants is shown to be very sensiti

In a prospective long-term outcome study of a representative sample of teenage-onset anorexia nervosa (AN), 51 individuals with AN, recruited after community screening, were contrasted with 51 matched comparison cases at a mean age of 24 years (10 years after AN onset). All 102 cases had been examined at age 16 and 21 years. At 24 years all probands were interviewed regarding mental and physical h

The distinction between fixed and variable factors of production and their corresponding costs has: long played a fundamental role in economic theory. However, in analyses of life history evolution a distinction between fixed and variable costs of reproduction has not been made. In this paper. I discuss these concepts and analyze some effects of fixed costs of reproduction on reproductive decision

The transcriptional machinery in individual cells is controlled by a relatively small number of molecules, which may result in stochastic behavior in gene activity. Because of technical limitations in current collection and recording methods, most gene expression measurements are carried out on populations of cells and therefore reflect average mRNA levels. The variability of the transcript levels

This thesis comprises general parametric models for surface roughness. The models can be used in several technical and natural applications but are here only applied to the micro-structure of paper. In that application, earlier models are generalized and new models introduced. The different models are related to the scale of the roughness and by using different approaches, different roughness prop

I uppsatsen gör en kombinerad idéhistorisk och narratologisk analys av Viktor Rydbergs ungdomsroman Vampyren. Berättelsen ligger nära den skräckromantiska genren och publicerades i Jönköpingsbladet 1848.

Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. This thesis presents an interactive prototyping tool called

We present new results on a study of the weak s-process elemental abundances in the M supergiant alpha Ori (M2Iab). We have conducted the abundance analysis through comparison of synthetic with observed spectra in the two infrared spectral regions 0.7 - 1.1 mu m and 2.1 - 2.3 mu m, where the molecular and atomic line densities are less than in the optical region and where many of the relevant elem
