Amongst the wear debris particles implicated in the particle hypothesis for prosthetic loosening are polymethylmethacrylate (PMMA), and particularly PMMA with barium sulphate contrast agent. Another suggested cause for loosening is hydrostatic pressure. PMMA particles were combined with hydrostatic pressure in a study to investigate whether there could be a synergistic or additive effect between t
Testicular development is an androgen-dependent process, and fetal exposure to antiandrogens disrupts male sexual differentiation. A variety of testicular disorders may result from impaired development of fetal Leydig and Sertoli cells. We hypothesized that antiandrogenic exposure during fetal development interferes with desert hedgehog (Dhh) signaling in the testis and results in impaired Leydig
A polymorphic microsatellite in intron 6 of the human proteasome core particle PSMA6 gene (HSMS006), and four other microsatellites localized upstream on human chromosome 14q13.2 (HSMS801, HSMS702, HSMS701, HSMS602), were genotyped in 104 type 2 diabetic patients and 129 age-matched control subjects from Latvia and replicated in 91 type 2 diabetic patients and 88 age-matched healthy control subjec
Biological production of hydrogen sulfide (H2S) using sulfate-reducing bacteria (SRB) has important potential within environmental biotechnology. The aim of this work was to study the possibility of using SRB for the treatment of an acid mine drainage (AMD) at bench-scale. This process involved three stages: the optimization of H2S production through the utilization of total volatile fatty acids (
β-Alanine synthase is the final enzyme of the reductive pyrimidine catabolic pathway, which is responsible for the breakdown of uracil and thymine in higher organisms. The fold of the homodimeric enzyme from the yeast Saccharomyces kluyveri identifies it as a member of the AcyI/M20 family of metallopeptidases. Its subunit consists of a catalytic domain harboring a di-zinc center and a smaller dime
The goal of the thesis is to present the thorough documentation and analysis of a private dwelling in Pompeii, the Casa del Torello di Bronzo (V 1,7), the largest and most dominating dwelling in insula V, and in particular its complex system of water use and distribution. The work is embedded in the on-going study of the entire insula, carried out by the Swedish Pompeii Project, so that it will ul
This paper looks at the how a new kind of South Scandinavian radical left emerged around 1990. It argues that its repertoire of contention neither can be understood as simply a product of struggles in local contexts or as diffusion of an already existing repertoire through trans-local mobilisations. The contingent history of the counter-claims to the far right Charles XII march in Lund throughout
Resolving complexes of closely related and cryptic insect species can be challenging, especially when dealing with rare and protected taxa that are difficult to collect for genetic and morphological analyses. Until recently, populations of the genus Osmoderma (Scarabaeidae), widespread in Europe, were treated as a single species O. eremita (Scopoli, 1763) in spite of observed geographic variation
Critique of religion and its consequences is a topical theme. The attack on the satirical magazine Charlie Hebdo in Paris in January 2015 made the Western media establishment to rally in defence of freedom of expression, but it also raised the question of the limits of this freedom. There are always defined limits to freedom of expression, which change over time and are adapted to the political sy
The origin of fine structure in the core-level photoemission spectra of the C2H4, C2D4, C2H3 and C2D3 molecules chemisorbed on Rh(111) is probed in a careful high-resolution study showing that this structure arises from internal molecular vibrations rather than from other chemically-shifted carbon atoms. It is shown by comparison of the adsorbate and gas-phase spectra that the underlying features
Organic farming not only increases plant diversity, but also simultaneously promotes biological weed control through provisioning of ample resources to seed predators. Harpalus affinis (Schrank, 1781) was collected from organically or conventionally managed winter-wheat fields with high or low surrounding shares of organic fields, aiming to test the impact of agricultural management on its activit
Since Solow (Q J Econ 70:65-94, 1956) the economic literature has widely accepted innovation and technological progress as the central drivers of long-term economic growth. From the microeconomic perspective, this has led to the idea that the growth effects on the macroeconomic level should be reflected in greater competitiveness of the firms. Although innovation effort does not always translate i
Silicon is a promising candidate to substitute or complement graphite as anode material in Li-ion batteries due, mainly, to its high energy density. However, the lithiation/delithiation processes of silicon particles are inherently related to drastic volume changes which, within a battery's physically constrained case, can induce significant deformation of the fundamental components of the battery
