Replacing fossil jet fuel with biojet fuel is an important step towards reducing greenhouse gas (GHG) emissions from aviation. To this end, Sweden has adopted a GHG mandate on jet fuel, complementing those on petrol and diesel. The GHG mandate on jet fuel requires a gradual reduction in the fuel’s GHG emissions to up to 27% by 2030. This paper estimates the potential production of biojet fuel in S
En större mängd kvartsavslag och brända ben, upptäckta vid rekognosering (Norrbottens Museum) av hyggesberedda ytor norr om byn Sammakko, c. 40 km SO Gällivare, har tolkats att indikera ett kortvarigt använt boplatsområde. Platsen, liggande c. 100 meter norr Linaälven och i kanten av en nästan igenväxt göl, genomgick arkeologisk förundersökning sommaren 2019. Insamlat material av brända ben ochA large number of quartz fragments from knapping andburnt bone, discovered during reconnaissance (NorrbottensMuseum) of forest-cleared areas north of the villageSammakko, c. 40 km SE of Gällivare, have been interpretedto indicate a short-term used dwelling site. Th esite, located c. 100 meters north of the Linaälven Riverand at the edge of an almost overgrown pond, underwentarchaeological prelimin
Objective: The purpose of this study was to explore the feasibility to determine regional diagnostic reference levels (RDRLs) for paediatric conventional and CT examinations using the European guidelines and to compare RDRLs derived from weight and age groups, respectively. Methods: Data were collected from 31 hospitals in 4 countries, for 7 examination types for a total of 2978 patients. RDRLs we
Wastewater sludge represents an important resource for reuse in agriculture. However, potentially harmful pathogens are a main threat in this context. Thus, the aim of this study was to examine the presence of helminth ova and protozoan cysts in dried sewage sludge samples collected from ten wastewater treatment plants (WWTPs) located in eight governorates in Tunisia. Based on morphological criter
Small- and medium-sized enterprises (SMEs) have inherent characteristics, which require specific solutions for improving the sustainability performance of their operations. The purpose of this paper is to increase the knowledge on barriers and enablers for the adoption of sustainable manufacturing by manufacturing SMEs and to provide insights into what enablers can be used to overcome existing bar
Searches for the lepton number violating decay and the lepton flavor violating and decays are reported using data collected by the NA62 experiment at CERN in 2017-2018. No evidence for these decays is found and upper limits of the branching ratios are obtained at 90% confidence level: , and . These results improve by 1 order of magnitude over previous results for these decay modes.
The alliance between the seemingly disparate Lebanese Christian party Free Patriotic Movement and the Shi’a organization Hezbollah has survived many local and regional upheavals since the signing of the memorandum of understanding (MoU) in February 2006. The pact was strengthened after the 2006 summer war and has stood for 15 years - despite political assassinations and low-intensity conflict in L
Metal-based shielding plays an important role in the attenuation of harmful and unwanted radiation at an accelerator-driven spallation neutron source. At the European Spallation Source, currently under construction in Lund, Sweden, metal-based materials are planned to be used extensively as neutron guide substrates in addition to other shielding structures around neutron guides. The usage of metal
Community radio can support the process of having a voicein one’s community as a part of civic action, and promotecommunity dialogue. However, older adults are underrepresentedas producers of community radio shows in the UK,and face different challenges to their younger colleagues. Byworking within the radio production group of an existingorganisation of older adults, we identify the motivations a
Dark matter particles, if sufficiently light, may be produced in decays of the Higgs boson. This Letter presents a statistical combination of searches for H→invisible decays where H is produced according to the standard model via vector boson fusion, Z(-)H, and W/Z(had)H, all performed with the ATLAS detector using 36.1 fb-1 of pp collisions at a center-of-mass energy of s=13 TeV at the LHC. In co
Severe obesity in adolescence profoundly impacts health and social well-being. Lifestyle modifications are seldom successful in maintaining sufficient weight loss to mitigate the risk of complications. Metabolic and bariatric surgery (MBS) is a standard treatment for adult patients and has emerged as an option for adolescent patients. Several high-quality studies of adolescent MBS show substantial
Objectives To estimate the relationship between EQ5D (three levels, UK version) and the Ankylosing Spondylitis Disease Activity Score (ASDAS) for use in the economic evaluation of health technologies for people with axial spondyloarthritis (axSpA). To compare against the relationship with the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Methods An electronic, prospective, Portugues
In this study an algorithm was developed for calculating maximum detectable distance (MDD) for mobile gamma-ray detection of lost sources in-situ for some common mobile spectrometer systems and gamma sources (137Cs and 60Co). The MDD is a function of detector efficiency, vehicle speed, acquisition time interval, radiation background level and accepted frequency of false alarms. To test its accurac
BACKGROUND: Plasma biomarkers for Alzheimer's disease (AD) have broad potential as screening tools in primary care and disease-modifying trials. Detecting elevated amyloid-β (Aβ) pathology to support trial recruitment or initiating Aβ-targeting treatments would be of critical value. In this study, we aimed to examine the robustness of plasma biomarkers to detect elevated Aβ pathology at different
We prove Nehari s theorem for integral Hankel and Toeplitz operators on simple convex polytopes in several variables. A special case of the theorem, generalizing the boundedness criterion of the Hankel and Toeplitz operators on the Paley Wiener space, reads as follows. Let = (0, 1)d be a d-dimensional cube, and for a distribution f on 2, consider the Hankel operator f (g)(x) = λ f (x + y)g(y) dy,
Background: Mohs micrographic surgery (MMS) is a precise, tissue-sparing surgical technique that offers superior cure rates compared to traditional surgical excision. However, the degree of difficulty of MMS depends on many variables, and consequently, the number of surgical stages required for each case is quite unpredictable.Objectives: To identify risk factors for complicated MMS, defined as MM
We focus on the task of estimating a physically plausi-ble articulated human motion from monocular video. Ex-isting approaches that do not consider physics often pro-duce temporally inconsistent output with motion artifacts, while state-of-the-art physics-based approaches have either been shown to work only in controlled laboratory conditions or consider simplified body-ground contact limited to f
Background: A feared cause of bacteraemia with Gram-positives is infective endocarditis. Risk stratification scores can aid clinicians in determining the risk of endocarditis. Six proposed scores for the use in bacteraemia; Staphylococcus aureus (PREDICT, VIRSTA, POSITIVE), non-β-haemolytic streptococci (HANDOC) and Enterococcus faecalis (NOVA, DENOVA) were validated for predictive ability and the
