This thesis analyzed the relationship between breastfeeding, nasopharyngeal colonization and acute otitis media (AOM) in children. Nasopharyngeal cultures were collected from 400 children and milk samples from their mothers in connection with the scheduled visits to well baby clinics at 1-3, 4-7 and 8-12 months of age, and episodes of AOM and URI were documented. The nasopharyngeal flora was acqui

In these notes we are going to present a technique which is a multi-dimensional analogue of some methods which are nowadays standard inscattering theory on the real line for the Schrödinger operator. These methods are based on the construction of operators intertwining the Schrödinger operator with the free operator, obtained when the potential term is removed. The multi-dimensional technique us

This paper argues that the Reformation and the adoption of Lutheranism as a state religion had a great and lasting impact on the history of the Aesopic fable in Sweden. During the 16th and early 17th century, it is shown, the genre was explicitly Lutheranized and ascribed vital functions in the process of Lutheran confessionalization within the Swedish national state. In particular, it is demonstr

Fine particle emissions were measured at two commercial grate fired boilers operating on moist fuel residues. The aim of this study was to characterize fine particle emissions with a view to pinpoint parameters influencing the emissions. Additionally effectiveness of used flue gas cleaning techniques was assessed. The results show that large quantities of fine particles are emitted to the atmosphe

There is a growing need for selective recognition of microorganisms in complex samples due to the rapidly emerging importance of detecting them in various matrices. Most of the conventional methods used to identify microorganisms are time-consuming, laborious and expensive. In recent years, many efforts have been put forth to develop alternative methods for the detection of microorganisms. These m

Background: Prognostic factors in patients with localized primary cutaneous malignant melanoma (CMM) are well described. However, prognostic factors for recurrence are less documented. Objectives: The aim of this study was to identify prognostic risk factors for first recurrence in patients with localized stages I-II CMM using population-based data. Methods: This study included 1437 CMM patients r

Overcoming type I migration and preventing low-mass planets from spiralling into the central star is a long-studied topic. It is well known that outward migration is possible in viscously heated disks relatively close to the central star because the entropy gradient can be sufficiently steep for the positive corotation torque to overcome the negative Lindblad torque. Yet efficiently trapping plane
