Piezoelectric ceramics -- as one widely commercialised group of smart materials -- exhibit a great potential for various engineering applications. Their high-frequency capabilities are in particular attractive for actuator and sensor devices, which nowadays are present in daily-life-technologies such as cellular phones, fuel injection systems, and so forth. At high loading levels however, severely

The three superdeformed (SD) bands in Ce-132 and the two SD bands in Ce-131 have been extended to higher spin, following experiments with the EUROBALL IV spectrometer. The two SD bands in Ce-131 have been linked together. However, despite the relatively high population intensity of the bands (up to 5% of the respective channel), it has not been possible to unambiguously link any of the five SD ban

Popular Abstract in Swedish Kroppens svar på vävnadsskada är avgörande för initierandet av läknings-processen och försvaret mot invaderande mikroorganismer. Det lokala samspelet mellan de olika cellerna i immunförsvaret sker genom cellsignalering via små proteiner kallade cytokiner. Ett kraftigt eller obalanserat svar kan medföra att inflammationsdrivande cytokiner (IL-6, IL-1, TNF) läcker ut i blCell-signalling via cytokines modulates the local response to surgical trauma, directs the immunologic response and initiates the healing process. Surgical trauma induces a systemic cytokine response and a down-regulation of the antigen presentation capacity of monocytes (HLA-DR expression), which is associated with a poor prognosis if pronounced. The aims with the studies in this thesis were to i

The molariform mandibular tooth development in wild boar has been described in order to increase the reliability and precision in age estimation. The age at eight different stages of tooth development has been determined based on radiographs of 114 mandibles. The method is applied to estimate age of death in 53 mandibles of juvenile wild boar and seasonality at the Late Mesolithic site of Ringklos

To estimate the long memory series in the framework of state space model is rarely documented although the theoretical foundation was well built in late 90s, and the literatures concentrate mainly on the estimation in stationary case. This paper aims to estimate the parameters in a wide range of long memory series by applying approximate Maximum Likelihood Estimation (MLE) and Bayesian Monte Carlo

Investigating the vadose zone, the physics behind the temporal and spatial instabilities of flow (in unsaturated media) is still of question. Although chaotic approaches have been widely employed for identifying different surface hydrology processes, such as rainfall, runoff, lake volume, etc., they were not applied for subsurface systems as much. On this ground, the present study attempts to inve
