With the attempts to increase power, efficiency and thrust, modern gas turbines operate with combustor outlet temperatures of 1800-2000 K, which are far beyond the allowable metal temperatures. Turbine blades are exposed to these high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is importan
Experiments were performed on the central pilot body (RPLrich- pilot-lean) of Siemens prototype 4th generation DLE burner to investigate the flame behavior at atmospheric pressure condition when varying equivalence ratio, residence time and co-flow temperature. The flame at the RPL burner exit was investigated applying OH planar laser-induced fluorescence (PLIF) and high-speed chemiluminescence im
The first part of the chapter provides an introduction on the implementation of quality-assurance programmes in nuclear medicine (NM) services. It is argued that participation in interlaboratory comparisons has two main benefits. First, on top of existing local quality-assurance programmes, participation can add a level of reassurance on quality. Second, interlaboratory comparisons are prerequisit
Aims: Testing insulin resistance could help improve physician assessment of patients’ risk of prediabetes or type 2 diabetes (T2D), even among normoglycemic individuals. Methods: The longitudinal study followed 16,333 normoglycemic participants in a nation-wide employer-sponsored health assessment program starting in August 2020 with a median follow-up time of 2.9 years for incident prediabetes or
Decarbonization in several countries is now linked to the prospect of implementing a national hydrogen economy. In countries with extensive natural gas infrastructure, hydrogen may provide a real opportunity to decarbonize space heating. While this approach may prove technically and economically feasible in the long-term, it is unclear whether consumers will be willing to adopt hydrogen-fueled app
BACKGROUND: Individuals adhering to a gluten-free diet (GFD) have been scarcely researched within a Chinese population. This present study was conducted to assess the characteristics, food choices, shopping preferences, and emotions and attitudes of individuals following a GFD.METHODS: Individuals following a GFD were invited to complete an online questionnaire about their demography and geography
Researchers in the field of molecular ecology and evolution require versatile and low-cost genetic typing methods. The AFLP (amplified fragment length polymorphism) method was introduced 10 years ago and shows many features that fulfil these requirements. With good quality genomic DNA at hand, it is relatively easy to generate anonymous multilocus DNA profiles in most species and the start-up time
We use cosmological zoom-in simulations of galaxy formation in a Milky-Way-sized halo started from identical initial conditions to investigate the evolution of galaxy sizes, baryon fractions, morphologies, and angular momenta in runs with different parameters of the star formation-feedback cycle. Our fiducial model with a high local star formation efficiency, which results in efficient feedback, p
Sixty-five patients who were primary or secondary refractory to melphalan/prednisone or other type of chemotherapy, or relapsed within 6 months after high dose chemotherapy with stem cell support, were given thalidomide at a dose of 200 mg/d escalating to 800 mg. The patients were followed for a median of 2 years and 22 weeks. Response was evaluated according to M-protein reduction combined with i
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
Ytelektromyografi (sEMG) mäter skelettmuskelfunktionen genom att registrera muskelaktivitet från hudens yta. Tekniken kan användas för att diagnostisera neuromuskulära sjukdomar och som ett hjälpmedel vid rehabilitering, biomedicinsk forskning och för interaktion mellan människa och dator. En simuleringsmodell för sEMG-data kan bedöma avkodningsalgoritmer och hjälpa till att utveckla nya diagnostiSurface electromyography (sEMG) measures skeletal muscle function by recording muscle activity from the surface of the skin. The technique can be used to diagnose neuromuscular diseases, and as an aid in rehabilitation, biomedical research, and human-computer interaction. A simulation model for sEMG data can assess decomposition algorithms and help develop new diagnostic tools. Such simulation mod
Many consider organic farming to be a solution to agriculture’s potential agricultural crises. Accordingly, the European Union’s Organic Action Plan aims to increase the share of organically farmed acreage drastically over the next decade. Research concerning the drivers of organic farming expansion could prove vital, and a wide range of empirical literature explores the topic. However, previous s
Biological tissues are strongly light-scattering and absorbing media that limit the depth of optical-based imaging. Even though, optical imaging provides good optical contrast information of biological content that is beneficial for clinical diagnostics application. Ultrasound was used to assist the optical-based imaging technique in overcoming the poor spatial resolution and shallow imaging depth
In the study, three unannounced evacuation experiments have been carried out in a cinema theatre. The evacuation experiments have been used to create a specific scenario and nine Swedish fire safety consultants have then been given an assignment to accomplish an evacuation simulation of the specific scenario. The study has shown that there are variations in the choice of input data for the evacuat
The Xga blood group is differentially expressed on erythrocytes from men and women. The underlying gene, PBDX, was identified in 1994, but the molecular background for Xga expression remains undefined. This gene, now designated XG, partly resides in pseudoautosomal region 1 and encodes a protein of unknown function from the X chromosome. By comparing calculated Xga allele frequencies in different
Small clusters of spherical colloids that mimic real molecules, so-called colloidal molecules, hold great promise as building blocks in bottom-up routes to new materials. However, their typical hard sphere nature has hampered their assembly into ordered structures, largely due to a lack of control in the interparticle interactions. To provide easy external control of the interactions, the present
”Bortom förnybart” är rapportens underrubrik men också en sammanfattning av en av de viktigaste slutsatserna från syntesarbetet. Fjärrvärmesverige har nästan uppnått sin vision om en fossilfri värmetillförsel. Detta är en fantastisk prestation som behöver ersättas av nya framtida miljö-, klimat- och samhällsmål att sträva efter. Framtida forskning kring fjärrvärme bör utgå från en tydligare vision
