An electron transfer mediator, 8-dimethylamino-2,3-benzophenoxazine (Meldola Blue), dissolved in the carrier solution in a flow-injection system, was found to reduce the oxidation potential for hydrogen peroxide from 600-1200 mV without mediator to - 100 mV vs. Ag/AgCl with the mediator present. The very low background current of reticulated vitreous carbon (RVC) at this potential makes it possibl

Historically, comprehensive studies of dilute ferromagnetic semiconductors, e.g., p-type (Cd,Mn)Te and (Ga,Mn)As, paved the way for a quantitative theoretical description of effects associated with spin-orbit interactions in solids, such as crystalline magnetic anisotropy. In particular, the theory was successful in explaining uniaxial magnetic anisotropies associated with biaxial strain and nonra

Carpal tunnel syndrome (CTS) is the most common nerve entrapment disorder worldwide. The epidemiology and risk factors, including family burden, for developing CTS are multi-factorial. Despite much research, its intricate pathophysiological mechanism(s) are not fully understood. An underlying subclinical neuropathy may indicate an increased susceptibility to developing CTS. Although surgery is oft

A major difficulty in assessing road traffic safety is the scarcity of historical accident data. xxThis is a common problem in contexts where a certain level of safety has been reached or where exposure is low, such as mixed traffic conditions with different levels of transport automation. Recent studies have demonstrated how severe interactions between road users and/or road users and infrastruct

Skolämnet Idrott och hälsa (IDH) har ett brett innehåll eftersom det inkluderar både idrottsaspekter och hälsoaspekter. Tidigare studier har visat att idrott-delen dominerar på flera sätt, delvis på grund av ett vagt och icke-specifikt ämnesspråk i ämnesplaner, kursplaner och läromedel (Lundin & Schenker 2021, 2022; Lundin m.fl. 2021, 2023). Detta resulterar i att hälsoaspekterna av ämnet inteThe school subject Physical Education and Health (PEH) has a wide scope with respect to its content, combining the aspects ‘sports’ and ‘health’. Previous studies have shown that for the Swedish school subject PEH, sports dominate the content of the subject in several aspects, as a result of, for instance, a vague and unspecific subject specific literacy used in the curricula and course books (Lun

Background: Smoking is probably the most important among preventable health risks. Health economic evaluation of smoking-cessation interventions, applying a lifetime perspective, is made possible by available epidemiological knowledge. The well established method of performing cost-effectiveness analyses of smoking-cessation interventions involves mathematical modelling (both deterministic and sto

Popular Abstract in Swedish Även om vi kanske inte tänker på det så ofta så är vår förmåga att bedöma likhet av stor vikt, inte minst då det gäller begreppsbildning och generalisering. Denna avhandling handlar om likhet, speciellt geometriska modeller av likhet. I sådana modeller representeras objekt som punkter i abstrakta rum, och likhet svarar (omvänt) mot avstånd i rummen. Avhandlingen tar uThis dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. The problems discussed concern the modelling of information integration behavior when concepts like asym

Popular Abstract in Swedish Svenska myndigheter behöver ibland samarbeta med utländska myndigheter, till exempel i ärenden som rör personer, föremål eller information som finns utomlands. Detta kan leda till komplexa juridiska problem som kräver pragmatiska lösningar. I avhandlingen undersöks rättsliga ramar för sådana lösningar. Undersökningen är särskilt inriktad på rättsligt bindande avtal som When Swedish administrative authorities co-operate with foreign administrative authorities, this may give rise to legally complex situations. This thesis investigates legal frameworks to solve the ensuing problems. The investigation in particular deals with binding agreements concluded by Swedish state authorities and municipalities with corresponding types of foreign public bodies. By the conclus

Background - Mitral annuloplasty is the most common surgical procedure performed for ischemic mitral regurgitation (MR). Surgical mitral annuloplasty is limited by morbidity, mortality, and MR recurrence. We evaluated the safety and feasibility of a transvenous catheter-delivered implantable device to provide a percutaneous alternative to surgical mitral annuloplasty. Methods and Results - Five pa

Background: In this study we investigated (a) to what extent physicians have experience with performing a range of end-of-life decisions (ELDs), (b) if they have no experience with performing an ELD, would they be willing to do so under certain conditions and (c) which background characteristics are associated with having experience with/or being willing to make such ELDs. Methods: An anonymous qu

Popular Abstract in Swedish I innemiljöer är ofta innertaken nedsänkta för att ge plats åt elinstallationer, ventilationsdon och dylikt. Om innertaken från början består av plattor som reflekterar ljud, så kan dessa perforeras och förses med porösa skikt, och därmed även användas som ljudabsorbenter. Mekanismerna för denna ljudabsorption är i princip välkänd, men det tillkommer bland annat en del The sound absorption characteristics of resonant absorbers, implemented as perforated suspended inner ceilings attached with thin porous layers, are investigated. Several existing theories model the principal absorption mechanisms, but the interaction with the outer sound field influences the absorption in ways that can be modelled with new approaches. The effect of arranging the absorbing surfac

PURPOSE. Cystatin C is a mammalian cysteine protease inhibitor, synthesized in various amounts by many kinds of cells and appearing in most body fluids. There are reports that it may be synthesized in the mammalian retina and that a cysteine protease inhibitor may influence the degradation of photoreceptor outer segment proteins. In the current study cystatin C was identified, quantitated, and loc

Popular Abstract in Swedish Popularized summary in Swedish (Sammanfattning på svenska) Blödarsjuka - hemofili - är en ärftlig sjukdom som endast uppträder hos män och som överföres av kvinnliga bärare vilka ej är blödare. Sjukdomen tar sig uttryck i en abnorm blödningsbenägenhet med framför allt ledblödningar och då redan från tidig ålder. Det finns två typer av blödarsjuka, hemofili A respektiveIn patients with severe hemophilia it is today possible to prevent the development of arthropathy by giving effective continuous prophylaxis from an early age, thus preventing the VIII:C or IX:C concentration from falling below 1% of normal. All the signs show that if a high-dose prophylactic regimen - that is, 3,000-5,000 U/kg body weight annually - is started as early as 1-2 years of age, the pa

While traditionally treated separately, the research disciplines dealing with electromagnetic fields respectively continuum mechanics are naturally connected. Not only are the basic equations formulated in a similar way, but the presence of electromagnetic fields affect the balance equations of continuum mechanics and likewise, the presence of material continua affect the electromagnetic fields

Despite the recent theoretical and empirical advancements in the geography of innovation literature regarding the role that global sources of knowledge may have for regional growth and development, research in this field remains focused on successful regions and clusters in developed countries. Hitherto there has been limited research on the role of regions located in developing countries and the

A laser diagnostic concept for measurement of potassium chloride (KCl) and potentially other alkali compounds in large-scale boilers and furnaces of limited optical access is presented. Single-ended, range-resolved, quantitative detection of KCl is achieved by differential absorption light detection and ranging (DIAL) based on picosecond laser pulses. Picosecond DIAL results have been compared exp

The Swedish Family-Cancer Database comprises a total of 11.8 million individuals covering the Swedish population of the past 100 years. Version VIII of the Database is described in the present article. Cancer cases were retrieved from the Swedish Cancer Registry for the period 1958-2006, including more than 1 million first primary cancers. The number of familial cancers in offspring is 14,000 when

Background. Concerns have been expressed about possible adverse effects of the use of antidepressant medication during pregnancy, including risk for neonatal pathology and the presence of congenital malformations. Method. Data from the Swedish Medical Birth Register (MBR) from 1 July 1995 up to 2007 were used to identify women who reported the use of antidepressants in early pregnancy or were pres

It is contended in this thesis that the introduction of a legal regime with a rateless structure, subject only to market forces and a rebuttable statutory presumption as to where the rate line of conscience should be drawn, can provide a solution if the rate charged by pawnbrokers is to be regulated. The thesis also shows that a uniform pawn ticket issued as a negotiable document of title, and tra
