Popular Abstract in Swedish En av dagens största utmaningar är de stadigt ökande utsläppen av förorenande avgaser och drivhusgaser. Den största delen av dessa föroreningar kommer från förbränningsanläggningar och fordon. För att kunna minska utsläppen måste man förstå förbränningsprocesserna, och hur man kan kontrollera förbränningen. Utmaningen är att förbränningprocesser är mycket komplexa. Det To deal with complex physical and chemical processes in reactive systems, such as combustion processes, it is necessary to find methods that simplify modelling in such a way that it becomes both more comprehensible and practically useful. In the work reported here a method for automatically reducing chemical reaction mechanisms has been developed for use in computer simulations of various combusti

Summary Anti-neutrophil cytoplasmic antibodies against proteinase 3 (PR3-ANCA) are used as diagnostic tools for patients with small vessel vasculitis (AASV). We have produced chimeric mouse/human PR3 molecules and investigate changes in reactivity over time and the possible relationship between epitope specificity and clinical course. Thirty-eight PR3-ANCA-positive patients diagnosed between 1990

Background-Fetal exposure to preeclampsia is associated with higher blood pressure and later risk of stroke. We aimed to investigate the associations of maternal preeclampsia, gestational hypertension, and maternal blood pressure change in pregnancy with offspring cardiac structure and function in adolescence. Methods and Results-Using data from a prospective birth cohort study, we included offspr

We demonstrate range-resolved detection of atomic hydrogen in methane/oxygen flames based on 2-photon excited backward lasing using 205-nm femtosecond laser pulses. Range resolution is achieved by temporally resolving the backward emission with a streak camera.

Extracellular vesicles (EVs) are a heterogeneous group of actively released vesicles originating from a wide range of cell types. Characterization of these EVs and their proteomes in the human plasma provides a novel approach in clinical diagnostics, as they reflect physiological and pathological states. However, EV isolation is technically challenging with the current methods having several disad

Purpose. The purpose was to evaluate the health-related quality of life (HRQL) of patients with pharyngeal carcinoma at diagnosis and after 1 and 5 years in relation to tumor location and treatment modality in a prospective multi-center study. Methods. Eighty-nine patients with pharyngeal carcinoma (mean age, 60.0 years; 76% men) were evaluated using the European Organization for Research and Trea

Amplification at the long arm of chromosome 8 occurs in a large fraction of breast and prostate cancers. To clone the target genes for this amplification, we used suppression subtraction hybridization to identify overexpressed genes in the breast cancer cell line SK-Br-3, which harbors amplification at 8q (8q21 and 8q23-q24). A differentially expressed gene identified by SSH, the p40 subunit of eu

We analysed the relative importance of individual versus institutional factors in explaining variations in the utilisation of physician services among the 50+ in ten European countries. The importance of the latter was investigated, distinguishing between organisational (explicit) and cultural (implicit) institutional factors, by analysing the influence of supply side factors, such as physician de

Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

Diagnostic reference levels are the main and the most effective tools of optimization of the radiation protection of patients from medical exposure. Diagnostic reference levels should be established based on theresults of dedicated dose surveys, allowing evaluating typical patient dose distributions in a selected dose quantity for the selected X-ray examinations. The aim of the current study was t

Pericles is usually viewed as a great statesman and clever leader of the Athenians. In the mid-fifth century BC, however, he seems to have been in serious political trouble and may well have been in danger of losing a political struggle against his opponent Kimon. The fact that his incentives changed considerably at this point in time seems to have escaped attention in the literature. In contrast,

Inom kärnkraftsindustrin är säkerhet den aspekt som prioriteras högst. Alla kärnkraftverk är designade för att i högsta möjliga mån förhindra läckage av radioaktivetet till omgivningen, både under drift och i händelse av en allvarlig olycka. Med anledning av detta är reaktorinneslutningens vägg en av de viktigaste säkerhetsrelaterade konstruktionerna vid en anläggning, detta då denna konstruktionSafety is the top priority at a nuclear facility. The nuclear power plants are designed to prevent radioactive leakage to the surroundings, both during normal operation as well as in case of a severe accident. One of the most important structures in a nuclear power plant, with regard to safety, is thus the reactor containment wall. The containment wall is the last main barrier to prevent radioacti

Objectives: This study was performed to investigate the protective effects of taurine (2-aminoethanesulfonic acid, TAU) on oxidative stress in the isolated mouse testicular mitochondria, mitochondrial membrane potential (MMP), viability and motility of the exposed sperms to the BPA. Methods: We treated epididymal spermatozoa obtained from mice and isolated mouse testicular mitochondria with BPA (0

Först halvledarteknik, sedan nanoteknik. Tillsammans utgör de huvuddelen av det vi definierar som modern teknik. Användandet av halvledare revolutionerade teknologin under mitten av 1900-talet genom möjligheten att kunna kontrollera halvledarmaterial till att vara antingen elektriskt isolerande eller ledande. Inom elektroniken utgör halvledarna den viktigaste beståndsdelen i till exempel datorer, The topic of III-V nanowires is still, after more than two decades, a growing and lively research area. The areas of application are wide and contain such important topics as energy harvesting, cheap and efficient lighting, high efficiency detectors and new types of electronics. III-V materials offer properties superior to the widely used Si. They can have considerably higher carrier mobility whic

Criminal recidivism is a major global concern. There is a well-known association between substance use disorders and offending. Yet, little is known about crime-specific recidivism. The aim of this study was to investigate the relationship between specific substance use and crime-specific recidivism. The study is based on 4207 Swedish prison clients with substance use assessed with Addiction Sever

Patients with mental illness have an increased risk of cardiovascular morbidity. The Swedish-developed Health Dialogue is a pedagogical tool to individualize lifestyle counselling, used in specific age-groups to improve lifestyle habits and decrease mortality, but not tested specifically for patients with mental illness. Patients > 18 years old seeking primary care due to symptoms related to menta

The assignment of products to storage locations significantly impacts the efficiency of warehouse operations. We propose a multi-phase optimizer for a Storage Location Assignment Problem (SLAP) where solution quality is based on a distance estimate of future-forecasted order picking. Candidate assignments are first sampled using a Markov Chain accept/reject method. Future-forecasted pick-rounds ar

Carrying capacity, a concept entrenched in the natural resources and environmental field for nearly two centuries, has continually evolved to address the conflicts and sustainability of the human- nature relationship. This paper introduces an analytical framework for understanding carrying capacity within the context of the human- nature relationship. It systematically reviews the progression of i
