This study aimed to test and validate a dual-time-window (DTW) protocol for 6-(fluoro-18F)-3-(1H-pyrrolo[2,3-c]pyridin-1-yl)isoquinolin-5-amine ([18F]MK6240) dynamic PET imaging in experimental datasets acquired in human subjects. Methods: DTW protocols were tested and validated in datasets previously collected in 25 participants: 13 were cognitively normal, 10 had mild cognitive impairment, and 2
BACKGROUND: The implementation of COVID-19 vaccination among older persons at nursing homes has lowered the infection-associated mortality considerably, but emerging virus variants and decline in vaccine-induced immunity over time necessitate examination of future booster dosing strategies. The overall aim of this study was to assess vaccine protection against COVID-19 mortality in relation to tim
Agarose gels have long been known to produce exceptionally large enhancements of the water H-1 and H-2 magnetic relaxation rates. The molecular basis for this effect has not been clearly established, despite its potential importance for a wide range of applications of agarose gels, including their use as biological tissue models in magnetic resonance imaging. To resolve this issue, we have measure
Stribeck's publications Wugellager fur beliebige Belastungen' and 'Die wesentlichen Eigenschaften der Gleit- und Rollenlager' were remarkable for their time. Many of the findings were revolutionary and are still considered quite modem. The method used by Stribeck to calculate load distribution between the balls within a ball bearing is still used today, otherwise, a full finite element analysis wo
Stimulation around the superior cerebellar peduncle or within the deep cerebellar nuclei is known to inhibit the inferior olive with a very long latency. It has been suggested that this inhibition is mediated by the GABA-ergic nucleo-olivary pathway, but alternative explanations such as activation of an indirect excitatory pathway or a pathway via the red nucleus are possible. A long-latency inhib
The aim of this work was to study the leaching of hazardous substances in additives and admixtures that are commonly contained in concrete. Time-dependent leaching has been analyzed for three types of metal containing concretes: with ordinary Portland cement (OPC), fly ash, and slag. The concretes had uniform leaching patterns, clearly above detection limits. The prolonged diffusion test of 1,700
Popular Abstract in Swedish Avhandlingen undersöker de två behandlingsalternativ, hemodialys och njurtransplantation, som är tillgängliga för personer med njursvikt. I fokus för undersökningen står de former av person- och patientskap som skapas och upprätthålls i hemodialys- och njurtransplantationsvården samt i de njursjukas vardagsliv. Ett av avhandlingens grundläggande antaganden är att dessa This thesis examines the practice of haemodialysis and kidney transplantation, the two medical therapies available for persons with kidney failure, from a phenomenological perspective. A basic assumption made in the thesis is that contemporary biomedicine is deeply embedded in the cultural, historical, economic, and political circumstances provided by the particular local, national, and transnatio
Popular Abstract in Swedish I centrum för min avhandling står den spanske dominkanen Alonso de Montúfar (ca.1489-1572) som mellan 1554 och 1572 var ärkebiskop av Mexiko. I synnerhet har jag studerat hur ärkebiskop Montúfar ville att kyrkan skulle organiseras (hans kyrkovision) och hur han försökte förverkliga sin vision (hans kyrkopolitik). Montúfar kom till Mexiko drygt trettio år efter den spanThis dissertation focuses on Archbishop Alonso de Montúfar OP (ca. 1489-1572). It seeks to explore two decades of sixteenth century Mexican Church History mainly through the study of documents found in Spanish and Mexican archives. Born outside Granada in Southern Spain, just after the conquest from the Muslims, Alonso de Montúfar assumed teaching and leading positions within the Dominican order.
Objectives. Accidents in health care, resulting in injury or death to the patient, are a matter of considerable concern. The aim of this study is to examine whether system weaknesses can contribute to these accidents, and if so, how. Design. Eight consecutive accidents reported to the Health Authority in Sweden were analysed using MTO (Man-Technique-Organization) analysis. Setting. Emergency care
The objective of this paper is to perform an empirical description and analysis of the duration of EU imports from the rest of the world. Toward this aim, we employ a rich data set of detailed imports to individual EU15 countries from 140 non-EU exporters, covering the period 1962-2006. Using these data, we both perform a thorough descriptive analysis of the duration of EU trade, and test the data
Popular Abstract in Swedish Shusaku Endo (1923-1960) är en romersk-katolsk, japansk romanförfattare. Från 1950-1953 studerade han fransk litteratur I Lyon, Frankrike.

Treating nitrogen-rich reject water from anaerobically digested sludge with deammonification has become a very beneficial side stream process. One common technique is the one-stage moving bed bioreactors (MBBRs), which in comparison with the other deammonification techniques can be started up without seeding anammox bacteria. This study investigated the impact of biofilm seeding on the start-up of
We reconstructed forest development and disturbance events (fire and logging) during the last 1000 yr with tree-ring data, pollen and charcoal analysis from a semi-natural Fagus sylvatica-Picea abies forest (ca. I km(2)) in the hemiboreal zone. According to pollen analysis, Quercus robur together with Pinus sylvestris was abundant in the forest until the turn of the 18th/19th centuries when these
Optimal migration theory predicts that birds minimizing the overall time of migration should adjust stopover duration with respect to the rate of fuel accumulation. Recent theoretical developments also take into account the wind situation and predict that there is a time window (a set of days) during which birds should depart when assisted by winds but will not do so if there are head winds. There
Bakgrund: Klientcentrering är centralt både inom arbetsterapi och andra professioner inom hälso- och sjukvård. Inom Barn- och ungdomshabiliteringen samt Vuxenhabiliteringen finns det ärenden med klienter där klientcentreringen kan kompliceras av att klienten är i behov av en sekundär person som hjälper till med kommunikation och delaktighet. Det saknas studier på hur arbetsterapeuter arbetar klienBackground: Client-centered care is significant in both occupational therapy and other professions within healthcare. Client-centered care can become complicated in errands within pediatric and adult habilitation services when the client is in the need of a secondary person to enable communication. Studies are scarce on how occupational therapists work client-centered in these errands. Aim: The st
