It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution an

This paper deals with the exterior Calderón operator for Lipschitz surfaces. We present a new approach of nding the norm of the exterior Calderón operator for this class of surfaces. The basic tool in the treatment is the set of eigenfunctions and eigenvalues of the Laplace-Beltrami operator for the surface. The norm is obtained as an eigenvalue problem of a quadratic form containing the exterior

Carbon fiber reinforced plastics, CFRP, are attractive materials not only because of their strength and stiffness but also because of their electrical conductivity and high thermal conductivity and diffusivity. One application where induction heating of CFRP is particularly interesting is tools for fast thermal cycling, beneficial in many industrial processes, for example in composite manufacturin

Over the last couple of decades an increasing use of temporary organizations has been observed in public administration, a development sometimes referred to as projectification. This article explores the political-administrative rationality of pro- jectification by studying the initiation and implementation of a project funding system regarding social investments in a Swedish municipality.

This thesis mainly explores how the molecular mobility of lipid and protein components in the outermost layer of the skin, the stratum corneum (SC), varies with different conditions and upon adding foreign compounds. These studies require methods that makes it possible to detect and characterize the minor amount of fluid components in the highly ordered solid SC sample with resolved molecular info

Autoxidation of SO2(aq) in the presence of manganese(II) is one of the important pathways for sulfuric acid formation in atmospheric clouds and fogs. Recent experimental results indicating that the catalyzed reaction takes place via a complex free-radical mechanism are discussed. Previous literature is reviewed in the light of this mechanism. Under atmospheric conditions of low total concentration

Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments. Development of the sources has been accompanied with equa

Popular Abstract in English All living things somehow communicate with each other. Cell-to-cell communication, or signalling, occurs on the molecular level, regulating the body’s activities and coordinating various cell actions and is thereby valuable for realizing cell as well as system functions. Errors in the cellular transferred information may induce diseases such as cancer and autoimmune disGlypicans are multifunctional cell surface heparan sulphate proteoglycans co-regulating numerous signalling pathways, and are thereby involved in the control of cellular division, differentiation, and morphogenesis. The heparan sulphate (HS) chains are responsible for many of those biological functions; nevertheless recent studies suggest functional roles for the glypican core proteins in mediatin
