The interplay between innovation and measurement has fascinated scholars from several disciplines over the last decade. All these diverse contributions, however, have resulted in a current state of knowledge that is signified by large numbers of articles without clear integration and synthesis. Therefore the aim of this explorative thesis is to examine the theoretical and empirical notions of inno
Objective: Higher gluten intake, frequent gastrointestinal infections and adenovirus, enterovirus, rotavirus and reovirus have been proposed as environmental triggers for coeliac disease. However, it is not known whether an interaction exists between the ingested gluten amount and viral exposures in the development of coeliac disease. This study investigated whether distinct viral exposures alone
Fungi play many essential roles in ecosystems. They facilitate plant access to nutrients and water, serve as decay agents that cycle carbon and nutrients through the soil, water and atmosphere, and are major regulators of macro-organismal populations. Although technological advances are improving the detection and identification of fungi, there still exist key gaps in our ecological knowledge of t
As a result of the huge economic and industrial development that human has been experiencing for decades or centuries, there are millions of potentially contaminated sites around the globe. Potentially contaminated sites are those which industrial, agricultural, mining and waste containment activities with potential to contaminate soil and groundwater has taken place in. A small number of these co
Background and purpose — Obesity defined as increased BMI is commonly associated with higher revision rates following total knee arthroplasty (TKA). We examined the effect of BMI on the rate of revision after TKA, for both infection and other reasons, and analyzed weight and height separately to provide better understanding of the risk profile. Patients and methods — The Swedish national knee arth
Objectives. The aim of this study was to investigate endothelium dependent relaxation (EDR) in coronary artery and the myocardial contractility after 24 h of non-ischemic heart preservation (NIHP). Design. Explanted cardioplegic hearts from six pigs were preserved by NIHP for 24 h. The perfusion medium consisted of an albumin containing hyperoncotic cardioplegic nutrition-hormone solution with ery
Failures in Alzheimer's disease (AD) drug trials highlight the need to further explore disease mechanisms and alterations of biomarkers during the development of AD. Using cross-sectional data from 377 participants in the BioFINDER study, we examined seven cerebrospinal fluid (CSF) and six plasma biomarkers in relation to β-amyloid (Aβ) PET uptake to understand their evolution during AD. In CSF, A
Background: Transoral robotic surgery (TORS) assisted base of the tongue (BOT) resection has been suggested as part of the work-up for head and neck squamous cell cancer with unknown primary (HNSCC-CUP). Success rates vary with regard to identification of primary BOT lesions, and cases with likely such lesions appear to be included in previous reports. Objectives: To analyse the possible benefits
The invariance of the power sum under a change of frame of reference is investigated and a theorem relating this invariance to the balance laws for mass, momentum and moment of momentum is proved. This gives a new perspective on previous similar results obtained by Noll, Beatty and Green and Rivlin.
The oxygen reduction reaction (ORR) activity can strongly affect the performance of solid oxide fuel cells (SOFCs). To improve the electron transfer and enhance active sites for reactions in cathode, La0.8Sr0.2MnO3 mixed with Y2O3-stabilized ZrO2 (LSM/YSZ) nanofibers were co-fabricated by the electrospinning method. The fibers were well characterized and the electrochemical properties were evaluat
