Popular Abstract in English From the pure technological perspective (leaving the business aside), the design of electronic devices, such as mobile phones, is an extremely complex process often involving a large number of disciplines, from mastering complicated mathematical models to proficiency of physical and electrical properties of specific materials involved in the manufacturing. In order to oThe methodology behind this work has been to use the concept of algorithm-hardware co-design to achieve efficient solutions related to the digital front-end in mobile receivers. It has been shown that, by looking at algorithms and hardware architectures together, more efficient solutions can be found; i.e., efficient with respect to some design measure. In this thesis the main focus have been plac

Manganese (Mn) is an essential nutrient in humans, but excessive exposure to Mn may cause neurotoxicity. Despite homeostatic regulation, Mn concentrations in blood vary considerably among individuals. We evaluated if common single-nucleotide polymorphisms (SNPs) in SLC30A10, which likely encodes a Mn transporter, influence blood Mn concentrations and neurological function. We measured blood Mn con

Hypoxia is a hallmark of solid tumors, which may offer opportunities for targeted therapies of cancer; however, the mechanisms that link hypoxia to malignant transformation and tumor progression are not fully understood. Here, we show that up-regulation of the polyamine system promotes cancer cell survival during hypoxic stress. Hypoxia was found to induce polyamine transport and the key enzyme of

It is well established that adaptive immune responses induced by hypercholesterolemia play an important role in the development of atherosclerosis, but the pathways involved remain to be fully characterized. In the present study we assessed immune responses to hypercholesterolemia induced by feeding Apoe-/- mice a high-fat diet for 4 or 8 weeks.

Modelling is a wide concept. This paper describes various meanings of modelling in relation to mechanical properties of wood and wood-based materials. Three examples of modelling by means of the finite element method, presented in recent years in PhD theses, are used as reference points. They relate to modelling of the micro-structure of wood and its mechanical properties, modelling of drying-indu

Efficient and suitable daily landfill cover is considered the most important aspect for minimising the negative impact of landfills on the local environment and population, especially in arid and semiarid countries. In this study, numerical model, HYDRUS-2D/3D, was used to investigate the impact of landfill cover type, cover thickness and antecedent water content on the quantity and the rate of co

Objectives. BMD in the hand, as evaluated by digital X-ray radiogrammetry (DXR), has been suggested to be a predictor for joint damage in RA. A predictor for long-term prognosis might also predict increased mortality in RA. The aim of the present study was to evaluate BMD in the hand as a predictor for all-cause mortality. Methods. In 1978, 152 consecutive patients (78% women, mean disease duratio
