Thin-section analysis of votive terracottas from the Etruscan sites Tessennano, Vulci, Tuscania and Tarquinia were made in order to help explaining the manufacturing process of votiv terracottas, with a focus on coice of raw material (clay and temper). The investigation of the material from these four sites has offered an opportunity to study Etruscan handicraft. The study has shown that e.g. that

In a preliminary study aimed at outlining the organization of affective categories in Romanian, several cases were identified where Romanians made use of two or more competing linguistic terms applied to what appeared to be the same conceptual configuration . One such case is taken into consideration in this 5-study follow-up investigation, whose purpose was to obtain empirical data for establishi
A paradigm shift is emerging in universities especially regarding how personalized and collaborative mobile learning should be addressed. Recently three international benchmarking projects on quality of e-learning in higher education have been carried out by Lund University in Sweden. These showed that quality has to be valued from a holistic perspective and to a higher extent from learning dimens
In this work benzoyl dextrans with a degree of substitution (DS) ranging from 0.02 to 0.29 and valeryl dextrans with a DS ranging from 0.025 to 0.2 were synthesized. The modified dextrans were characterized by viscosity, UV, HPLC and NMR measurements. The effect of reaction conditions on the DS of modified dextrans was studied. The modified dextrans were used to study the effect of aromatic and al
Planning and scheduling are considered as one of the most difficult but most important processes from perspectives of project management. These processes involve implementation of a widerange of planning methods used by different organizations with various levels of planning knowledge. The planning methods for scheduling can be classified as traditional methods (e.g. line of balance, Gantt chart a
The thesis is based on five investigations. In the first study the nature and the degree of cognitive impairment of patients with frontotemporal dementia (FTD) is explored. The results from neuropsychological assessment are described as three levels of cognitive impairment. These levels of functional disturbance corresponded to increased severity of abnormality of the regional cerebral blood flow
The effects of different parameters of interest for the localization of malignant tumours in situ by means of laser-induced fluorescence and haematoporphyrin derivatives were investigated. Such parameters are drug composition, drug concentration, laser pulse energy and excitation wavelength. In order to assess the relative merits of the two tumour-seeking agents Photofrin (haematoporphyrin derivat
This paper studies how to design the spectrum of a UWB signal in accordance with the FCC regulations and IEEE 802.15.3a recommendations. We show that the "conventional" UWB system with pulse-position modulation and time-hopping multiple access gives rise to spectral lines that violate the regulations. The impact of different modulation and multiple access schemes on the spectrum shaping is derived
‘This study examines the collection and recycling systems in selected countries in Europe – Finland, Germany, Sweden, Switzerland and United Kingdom – where such systems are already in place based on legislation. Based on the review of various written sources as well as interviews with stakeholders (manufacturers, producer responsibility organisations, national government officials, distributors/n
The paper examines the impact of Rician fading on the orthogonality of dual-polarized MIMO channels in a measured urban macrocellular scenario. The measurements confirm the previous finding that the Rician

Popular Abstract in Swedish Prostatacancer är Sveriges vanligaste cancersjukdom bland män. Många av de som diagnosticeras med prostatacancer får inga besvär men cirka 2400 män dör årligen av sjukdomen. Det finns flera behandlingsmetoder mot prostatacancer, men för kastrationsresistent prostatacancer, en avancerad form av prostatacancer, finns idag ingen botande behandling. Det utvecklas dock allt Prostate cancer is one of the major causes of cancer related deaths in men in Europe and the United States. In this doctoral thesis, radioimmunoimaging and -therapy of prostate cancer was investigated pre-clinically by targeting the human kallikrein-related peptidase 2 (hK2) with radiolabelled monoclonal antibodies. hK2 is an antigen that is over-expressed in prostatic neoplasms and is closely rel
PCR is widely employed as a rapid, sensitive and specific molecular diagnostic technique in clinical diagnosis, environmental investigations and for monitoring biotechnical processes. However, the full potential of diagnostic PCR is limited, in part, by the presence of PCR-inhibitory substances in biological samples. Among the mechanisms by which these inhibitors may act are through interfering wi
