The aim was to examine tissue expression of Ku protein in lower lip salivary gland (LSG) biopsies from cases of primary Sjogren's syndrome (SS) and from normal subjects. Methods: immunohistochemistry was used with antibodies to Ku70/86 and also Ki67, PCNA and p53. In addition, the Klenow method was applied in order to detect evidence of apoptosis. Sections of hyperplastic tonsil served as addition
In acetonitrile, polyisoprene-b-poly(methyl methacrylate) (PI−PMMA) diblock copolymers form starlike micelles with a dense core of the insoluble PI blocks and a soft solvent-swollen corona of the soluble PMMA blocks. Static and dynamic light scattering experiments in combination with viscosity measurements show that these micelles behave hydrodynamically as hard spheres. The block copolymers are l
In this article, we explore energy transfer processes within a series of Zn-porphyrin-appended dendrimers by means of excitation intensity dependent transient absorption measurements. We report singlet-singlet annihilation on two distinct time scales of 18 +/- 5 ps and 130 +/- 10 ps in the dimer and the dendrimers. The two distinct processes reflect the presence of two structural conformer distrib
In this chapter, I argue that moving as a way to counter the negative aspects of ageing (actual as well as symbolic), is both dependent on mobility and contradictory to it. The overall purpose is to investigate the relation between moving and mobility in the accounts told by people who have chosen to migrate as seniors in order to enable a certain lifestyle. In what way does the discursive ideal o
beta-Haemolytic streptococci of groups C (GCS) and G (GGS) from human infections typically belong to Streptococcus dysgalactiae and are important human pathogens. Among GGS (183 isolates), several emm-types were identified without significant differences between different sites of isolation. For GCS (79 isolates), the type-distribution was markedly different and more restricted.

Background: Patients with alcohol and other drug use disorders (AOD) frequently have multiple social, physical, and mental health treatment needs, yet have difficulty accessing community services, including drug abuse treatment. One strategy for linking patients with AOD with relevant services is case management, where a single case manager is responsible for linking patients with multiple relevan
This paper deals with bandwidth allocation in a Bluetooth scatternet. The proposed assignment of transmission rights provides a controlled traffic transfer between Bluetooth piconets and represents a key component in an ad-hoc wireless Bluetooth network in order to provide with efficient data packet passing within and across piconets. This assignment is obtained by executing a distributed algorith
Thermographic phosphors can be robust temperature remote sensors. The accuracy of the temperature measured by the phosphor is highly dependent on the quality of the phosphor calibration used. Conventionally, thermographic phosphors are calibrated by measuring a series of decay curves at known stable oven temperatures. The process is then repeated covering the thermal sensitivity range of the phosp
Popular Abstract in Swedish En central fråga av både teoretisk och praktisk betydelse är varför vissa företag är mer framgångsrika - vilket ofta uttrycks som att de har större konkurrensfördelar - än andra. Speciellt uppkommer frågan då vissa fabriker inom samma företag år efter år uppvisar ett bättre ekonomiskt resultat än andra. Fokus i denna avhandling är att förstå varför så sker inom ett utvaThe most central question in the strategic management literature is why some firms are more successful than others, often expressed as an aim to understand sources of competitive advantage. In this thesis, an empirical observation is made that a number of manufacturing plants belonging to the same firm show sustainable differences in financial success, and the question is why. The main theoretical
Purpose – In the recent redefinition of the European Commission's corporate social responsibility (CSR) strategy, attention is brought to CSR as a motor for innovation. However, literature in the area remains scarce. This chapter describes and discusses innovation as a consequence of a firm's CSR activities. Methodology/approach – The empirical part of the chapter is based on the content analysis
This chapter starts with a description of the optics of camera-type eyes, in which an image is projected upon a retina with cornea and lens as refracting elements. Ray tracing is explained with the human eye as an example of a terrestrial vertebrate's eye. Then the comparison is made to camera eyes of aquatic and amphibious animals, with an explanation of different kinds of aberrations, difficulti
This chapter focuses mainly on quality and a frame of reference to understand M-learning dimension concerns as course design, learning design, and media design and content. Consistent layout and design, clear organization, and presentation of information, consistency, easy-to-use navigation, and aesthetically pleasing design and graphics are dimensions that also have to be taken into consideration
