Antiarrhythmic effects of melatonin have been demonstrated ex vivo and in rodent models, but its action in a clinically relevant large mammalian model remains largely unknown. Objectives of the present study were to evaluate electrophysiological and antiarrhythmic effects of melatonin in a porcine model of acute myocardial infarction. Myocardial ischemia was induced by 40-min coronary occlusion in

Aging buildings will sooner or later be in need of renovation, which opens opportunities to reduce energy use. Even if economically feasible energy measures or technologies exist, they are not always implemented, leading to an energy efficiency gap. This dissertation deals with how energy measures are handled and why they are enabled or disabled during the planning and design of renovations. Durin

A producer-independent, problem-oriented, group-education programme with 2-day meetings on drug treatment in primary health care (PHC) was developed and evaluated. Initially, it was tested on a selected group of general practitioners (district physicians), using a non-exposed group as control. A comprehensive questionnaire was used to test changes in attitudes. There was a significant change in at

Music criticism has grown to become an important part of the modern cultural landscape, functioning as a mediating link between artistic expression and the audience. By evaluating music, journalists are in a position of symbolic power. Reviews are based on a subjective perspective but gain legitimacy through social and cultural frameworks. This raises a critical question: what happens when the soc

This thesis examines Swedish national role conceptions and the extent of role contestation in the Swedish Parliament’s Committee on Foreign Affairs (Utrikesutskottet) in the context of Sweden’s recent changes in security and foreign policy. Drawing on role theory, particularly the concepts of national role conception and domestic role contestation, the study investigates (1) which national self-im

The difference between the English North and South has long been a defining feature within the political and economical debate of the United Kingdom. Research has traditionally been done either explaining the regional inequalities of the region or the examination of the difference in material indicators such as income and employment. This thesis explores the role of the media and how the media dis

Iran’s extraterritorial violence constitutes a structural element of state policy, implemented through a coordinated system of intelligence services, diplomatic platforms, proxy militias, and criminal intermediaries. Rooted in revolutionary doctrine and operationalized by institutions such as the Islamic Revolutionary Guard Corps (IRGC) and its external arm, the Quds Force, this apparatus has enab

The ALICE Collaboration presents a new suite of jet substructure measurements in Pb–Pb and pp collisions at a center-of-mass energy per nucleon pair sNN=5.02 [Figure presented]. These measurements provide access to the internal structure of jets via the momentum and angle of their constituents, probing how the quark–gluon plasma modifies jets, an effect known as jet quenching. Jet grooming additio

Nutrient availability is of major importance for plant productivity. When estimating long-term sustainability from a nutrient perspective it is therefore interesting to focus on long-term changes in the soil nutrient pools when comparing different forest types. Here, we have highlighted some factors of importance for long term nutrient sustainability (e.g., several forest rotations) and pointed ou

The effects of the polyamines putrescine, spermidine and spermine on the mechanical activity in smooth muscle from guinea-pig taenia coli were investigated. Tissue concentrations of spermidine and spermine were about 240 and 160 nmol g-1, respectively, while the putrescine concentration was much lower (4 nmol g-1). Intracellular [Ca2+] was determined using the Fura-2 method and the effects of extr

This thesis investigates how human rights responsibility is constructed and negotiated between the Zambian state and foreign mining companies in Zambia’s mining sector under conditions of economic dependence on foreign investment. The study is motivated by observations from an internship in Zambia, where mining was consistently framed as central to development while questions of responsibility rem

The geopolitical competition between the United States and China over artificial intelligence has emerged as one of the defining dynamics of the 21st century. Yet despite a growing body of work on AI innovation, a structured and recent sectoral comparison of the conditions organizing AI development in each country remains underexplored. This thesis addresses that gap by applying Malerba's (200
