A Modelica Library for Paper Machine Dryer Section Modeling - DryLib - and applications

Following increased efforts during the last decade to formulate mathematical models for the paper drying process, this paper presents a Modelica library, DryLib, which enables users to rapidly develop complex models of paper machine dryer sections. In addition, parameter optimization, model reduction and moisture control by means of Non-Linear Model Predictive Control is treated. These application

What determines the current presence or absence of permafrost in the Tornetrask region, a sub-arctic landscape in Northern Sweden?

In a warming climate, permafrost is likely to be significantly reduced and eventually disappear from the sub-Arctic region. This will affect people at a range of scales, from locally by slumping of buildings and roads to globally as melting of permafrost will most likely increase the emissions of the powerful greenhouse gas methane, which will further enhance global warming. In order to predict fu

Allergic disease, immunoglobulins, exposure to mercury and dental amalgam in Swedish adolescents

High-dose exposure to inorganic mercury in man can influence the immune system and in rare cases cause immune-related disease. Some experimental animals also react with autoimmunity after low doses of inorganic mercury. Glomerulonephritis and an increased formation of immunoglobulin type E (IgE) are characteristic of these reactions. A recent study of 15-year-old adolescents demonstrated an associ

Risk factors for hip fractures in a middle-aged population: a study of 33,000 men and women.

Knowledge about subjects who sustain hip fractures in middle age is poor. This study prospectively investigated risk factors for hip fracture in middle age and compared risk factors for cervical and trochanteric hip fractures. The Malmo Preventive Project consists of 22,444 men, mean age 44 years, and 10,902 women, mean age 50 years at inclusion. Baseline assessment included multiple examinations

Vascular effects of anandamide and N-acylvanillylamines in the human forearm and skin microcirculation.

1 The endocannabinoid anandamide is an emerging potential signalling molecule in the cardiovascular system. Anandamide causes vasodilatation, bradycardia and hypotension in animals and has been implicated in the pathophysiology of endotoxic, haemorrhagic and cardiogenic shock, but its vascular effects have not been studied in man. 2 Human forearm blood flow and skin microcirculatory flow were reco

Heritability of blood pressure: monogenes and polygenes

High blood pressure (BP) is associated with cardiovascular morbidity and mortality. Both genetic and environmental factors are implicated in BP homeostatsis and hypertension development. The aims of the present theisis were: (a) to test if ambulatory BP (ABP) is better than office BP (OBP) to capture the heritable part of BP and if BP variability (BPV) measured by ABP monitoring is a heritable tra

Health Promotion Intervention in Mental Health Services

Popular Abstract in Swedish Syftet med denna avhandling var att definiera och utveckla begreppet hälsofrämjande i psykiatrisk vård samt att utveckla ett frågeformulär som syftar till att mäta patientens upplevelser av hälsofrämjande interventioner i psykiatrisk vård. Deltagarna bestod av 12 patienter i studie I och 12 sjuksköterskor i studie II samt 135 patienter i studie III och IV, alla deltagarThe aim of this thesis was to define and develop the concept of health promotion in mental health services as well as to develop a questionnaire to measure patients? subjective experiences of health promotion intervention in mental health services. The samples consisted of 12 patients in study I and 12 nurses in study II as well as 135 patients in mental health services in study III and IV. Data w

Prosodic Phrasing in Spontaneous Swedish

Popular Abstract in Swedish Den här studien behandlar prosodisk frasering. Det talade språket fraseras på ett sådant sätt att ord som hör nära samman innehållsmässigt och/eller syntaktiskt också produceras tillsammans i en grupp. Mellan ordgrupperna – de s k prosodiska fraserna – hör vi gränser. De prosodiska frasgränserna kan således sägas vara det talade språkets punkter och kommatecken. De spelOne of the most important functions of prosody is to divide the flow of speech into chunks. The chunking, or prosodic phrasing, of speech plays an important role in both the production and perception of speech. This study represents a move away from the laboratory speech examined in previous, related studies on prosodic phrasing in Swedish, since a spontaneous, Southern Swedish speech material is

Housing standards, environmental barriers in the home, and subjective general apprehension of housing situation among the rural elderly.

The aim of this study was to describe housing standards, physical environmental barriers in the homes and housing accessibility in relation to elderly people’s subjective general apprehension of their housing situation. By means of a novel instrument for home assessments, the Enabler, a rural population sample of individuals aged 75-84 years was surveyed. The results demonstrated that the responde

Theoretical oscillator strengths and hyperfine structure in HgII

We present a theoretical model ion for Hg II, including oscillator strengths and hyperfine structure constants for a large number of transitions and levels. Different computational models have been used, depending on the observability of the lines and their importance in spectral synthesis of stellar atmospheres. For the resonance lines, we use highly systematic, accurate, and fully relativistic m

Antagonism of thromboxane receptor induced contractions in isolated human groin lymphatics

In vitro studies were performed on lymphatics obtained from the groin in 19 patients undergoing vascular surgery. The lymphatics were mounted in tissue baths, and isometric contractions were induced by increasing concentrations of the thromboxane A2 (TXA2) mimetic U-46619. In comparison to K+ (124mM)-induced contraction, which were used as an internal standard, the response to U-46619 had an Emax

Polychlorinated biphenyls in the air of southern Sweden - spatial and temporal variation

Polychlorinated biphenyls in the lower atmosphere were studied over a regional area covering approximately 11000 km(2) in southern Sweden. Sampling were performed in 1992-1993, continuously during one year, where samples from 11 sampling-sites (in all 260 samples) were analysed. PCB concentrations ranged over two order of magnitudes, 7-983 pg m(-3). Differences in PCB concentrations among the samp
