To fulfill increasing requirements within the manufacturing sector, highly flexible and adaptable automation systems are needed. It is desirable to have one integrated approach that stretches from the process planning phase, through the implementation phase and all the way to the phase for execution of the process control logics. One promising approach is to use the concepts of service-oriented ar
The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. The deregulated market together with distributed generation have then pushed the system to operate during circumstances for which it was not desig
In this thesis aspects of peripheral B lymphocyte differentiation were studied. Through in vitro experiments, B lymphocyte activation was assessed. B lymphocytes express immunoglobulin (Ig) specific for a certain antigen on the cell surface, and when surface Ig is crosslinked by an antigen, the cell is activated. Antigens giving rise to a T cell dependent immune response are internalized by the B
This dissertation deals with discrimination of part-time and fixed-term workers. The EU directives on part-time and fixed-term work, as well as Swedish law in the same area, are the starting point of the analysis. The aim is to offer a reading of discrimination law as an instrument for freedom from subordination. Inspiration is found in critical legal positivism’s idea of the autonomous individual
This thesis consists of four self-contained, yet related articles which all contribute mainly to the corporate governance literature. Very broadly, the first two papers are on family firms and large shareholders in Sweden while the second two are on Enterprise Risk Management (ERM) practices in Nordic countries. The contribution of Paper 1 is that I for the first time take into account the two dim
För drygt tio år sedan startades det s.k. mellanstadieprojektet – numera ”femteklassprojektet". Det hela går ut på att teknologer besöker mellanstadieklasser, i första hand femteklasser. Besöket inleds med ett antal spännande demonstrationsförsök ("teknik-, kemi- och fysikshow"). Teknologerna berättar om sig själva, om vad man gör på den tekniska högskolan och vad LTH är för någonting. Ett viktigt
The intestinal flora and the bacteria found in the extraintestinal sites were studied in liver injury rats, with or without Lactobacillus plantarum 299v pre-treatment. The dominating intestinal flora and translocating bacteria were typed by RAPD and identified by 16S rDNA sequencing. It was proved that bacterial strains from the intestine could pass through the intestinal barrier to the extraintes
Protecting biodiversity and enhancing the provision of ecosystem services are key challenges for managing European agricultural landscapes. However, current approaches as implemented in the Common Agricultural Policy (CAP) of the European Union (EU) have been limited in their effectiveness to deliver positive biodiversity outcomes. To improve this situation, it is important to consider not only in
In the β-d-galactopyranoside-binding protein galectin-3, synthetic inhibitors substituted at the 3-position of a thiodigalactoside core cause the formation of an aglycone binding pocket through the displacement of an arginine residue (Arg144) from its position in the apoprotein. To examine in detail the role of different molecular interactions in this pocket, we have synthesized a series of nine 3
One of the major causes of premature failure in asphalt pavements is moisture damage. Asphalt mixtures designed without considering climate impacts may suffer from durability problems caused by movement of water inside the asphalt mixture. Rolling traffic over wet pavement builds up pore pressure in the mixture, which will consequently accelerate deterioration. The objective of the study was to as
Avian haemosporidians are vector-transmitted blood parasites that are distributed worldwide, abundant in many bird families and well studied across Europe and North America. Since avian haemosporidians have been poorly examined in the Palearctic migratory flyways of the Western Balkans, the goal of this study was to investigate which species of three haemosporidian genera, Plasmodium, Haemoproteus
Background: Most validations of paediatric glomerular filtration rate (GFR) estimating equations using standardized creatinine (CR) and cystatin C (CYS) assays have comprised relatively small cohorts, which makes accuracy across subgroups of GFR, age, body mass index (BMI) and gender uncertain. To overcome this, a large cohort of children referred for GFR determination has been established from se
Background: Acquired loss of the largest von Willebrand factor multimers is a common hemostatic disturbance in patients with aortic valve stenosis (AS), resulting in impaired platelet adhesion and increased bleeding risk. AS is also associated with atherosclerosis and myocardial infarction (MI). Our aim was to study the clinical outcomes associated with AS in MI patients treated with dual antiplat
Introduction: The thrombin generation assay-calibrated automated thrombogram (TGA-CAT) method is used to measure the overall coagulation capacity in plasma. However, the method is still considered to be a research tool, mainly because of its’ lack of standardization. Aim: Our study aimed to further raise the standardization level for the TGA-CAT method by evaluating a detailed standardization prot
Background: Mothers of preterm infants are at greater risk of symptoms of stress and anxiety compared to mothers of term infants. Aims: This study aimed to explore mothers’ experiences after coming home from the hospital with a moderately to late preterm infant. Methods: A qualitative and explorative method was used. Ten mothers who had given birth to a preterm baby with a gestational age between
Non-muscle invasive bladder cancer is marked by frequent recurrences and a risk for progression to life threatening disease. Intravesical Bacillus Calmette-Gúerin (BCG), one of the earliest effective immunotherapies for cancer, remains the current standard for treating high-risk non-muscle invasive bladder cancer. Optimal treatment with BCG includes periodic 3 weekly maintenance instillations, oft
A simple portfolio choice model shows that, when a bank's capital is constrained by regulation, regulatory cost (risk weightings) alters the risk and value calculations for the bank's assets. In particular, we find that banks may respond to stricter regulation by increasing the share of high-risk assets. Our empirical results show that US banks responded to the implementation of the stricter Basel
