Trans-tibial amputees with different indications for amputation often have stump problems. Many active amputees have limits in daily life and sports activities because of pressure ulcers, friction, allergic dermatitis or volume changes. Many methods and materials have been tried to make a well-fitted socket. A new polyurethane concept had been designed with a shock absorbing effect. The purpose of

A simple model is presented which interpolates between the DGLAP and BFKL regimes in deep inelastic cp scattering. This model is based on the CCFM and LDC models, and it is simple enough to provide an intuitive picture of the transition region between the two domains. Results are presented for both fixed and running coupling; for fixed coupling the transition between the domains occurs at a consta

The aim of the Swedish educational policy is educational participation and academic achieivement for all children, irrespective of ethnic background. Majority language instruction is an important tool used to achieve this goal. We argue that taking lessons in Swedish-as-a-second-language (S2) sets children apart in their class and limits their possibilities to interact with Swedish children and th

Popular Abstract in Swedish Denna avhandling handlar om hur man kan mäta små mängder av ett antal intressanta molekyler i en vattenlösning med hjälp av infrarödspektroskopi. Det är viktigt att kunna bestämma mängden av olika spårämnen i en vattenlösning i en rad olika tillämpningar. Några viktiga exempel på sådana tillämpningar är inom sjukvården för diagnostiska ändamål, bland annat för blodprovsThis thesis treats various aspects of the measurement of trace components in aqueous solutions with Fourier transform infrared spectroscopy. This technique has several applications from such diverse fields as dairy industry and biomedical optics. The use of infrared spectroscopy for trace component quantification is made difficult by the large absorption of water which dominates the spectrum. The

Background: Laser photocoagulation is a well-established treatment for diabetic retinopathy but the mechanism behind its effectiveness has not been elucidated. The protein kinase C (PKC) family is a group of enzymes which has been the subject of extensive interest in clinically related research since the advent of its role in the pathogenesis of diabetic retinopathy. With this study we wanted to e

Författaren Per Olov Enquists förslag att ”stryka” Gamla testamentet och delar av Nya testamentet kritiseras, särskilt utifrån en jämförelse med Deutsche Christens motsvarande förslag 1933. Jag ifrågasätter också Enquists uppfattning att det inte skulle finnas någon ”kollision” mellan de fyra evangelierna och ”upplysningstanken”.

Vitamin D deficiency is associated with susceptibility to tuberculosis, and its biologically active metabolite, 1 alpha,25 dihydroxyvitamin D-3 (1 alpha,25(OH)(2)D-3), has pleiotropic immune effects. The mechanisms by which 1 alpha,25(OH)(2)D-3 protects against tuberculosis are incompletely understood. 1 alpha,25(OH)(2)D-3 reduced the growth of mycobacteria in infected human PBMC cultures in a dos

Decision making for incompetent patients is a much-discussed topic in bioethics. According to one influential decision making standard, the substituted judgment standard, the decision that ought to be made for the incompetent patient is the decision the patient would have made, had he or she been competent. Although the merits of this standard have been extensively debated, some important issues h

Aqueous Co(II) sorption onto alpha-Al2O3 at pH 8.1 and surface concentrations (Gamma) of 0.16 to 11.3 mu mol m(-2) has been studied by XAFS spectroscopy. At low Gamma, Co adsorbs in a monodentate fashion or in a bridging bidentate fashion and is present as small oligomers. A Co(OH)(2)-like phase forms at high Gamma.

The preparative cell separation is an intrinsic requirement of various diagnostic, biotechnological and biomedical applications. Affinity chromatography is a promising technique for cell separation and is based on the interaction between a cell surface receptor and an immobilised ligand. Most of the currently available matrices have pore size smaller than the size of the cells and are not suitable

The effects of 'natural' disasters in cities can be worse than in other environments, with poor and marginalised urban communities in the developing world being most at risk. To avoid post-disaster destruction and the forced eviction of these communities, proactive and preventive urban planning, including housing, is required. This paper examines current perceptions and practices within internatio
