Tidskriftsartikel (refereegranskat)abstract
- Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference –1·69 [–9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5–8] vs 6 [5–8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52–23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75–0·86]; p<0·0001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status. Funding: No funding.

Effect of peak power in reactive high power impulse magnetron sputtering of titanium dioxide

Tidskriftsartikel (refereegranskat)abstract
- The effect of peak power in a high power impulse magnetron sputtering (HiPIMS) reactive deposition of TiO(2) films has been studied with respect to the deposition rate and coating properties. With increasing peak power not only the ionization of the sputtered material increases but also their energy. In order to correlate the variation in the ion energy distributions with the film properties, the phase composition, density and optical properties of the films grown with different HiPIMS-parameters have been investigated and compared to a film grown using direct current magnetron sputtering (DCMS). All experiments were performed for constant average power and pulse on time (100W and 35 mu s, respectively), different peak powers were achieved by varying the frequency of pulsing. Ion energy distributions for Ti and O and its dependence on the process conditions have been studied. It was found that films with the highest density and highest refractive index were grown under moderate HiPIMS conditions (moderate peak powers) resulting in only a small loss in mass-deposition rate compared to DCMS. It was further found that TiO2 films with anatase and rutile phases can be grown at room temperature without substrate heating and without post-deposition annealing.

REACTIVE CONTROL OF BYPASS TRANSITION IN A WING BOUNDARY LAYER
- 2022

Ingår i: 33rd Congress of the International Council of the Aeronautical Sciences, ICAS 2022. - : International Council of the Aeronautical Sciences. ; , s. 3037-3047

Konferensbidrag (refereegranskat)abstract
- This investigation deals with the numerical implementation of a data-driven method for reactive control of the boundary-layer over a NACA0008 airfoil. The aim of this work is to evaluate the performance of controller in damping the flow disturbances and its efficiency in delaying laminar-turbulent transition. We focus our attention on the bypass transition scenario caused by free-stream turbulence. In this scenario, the perturbations in the wing boundary-layer develop into streaky structures. We show that this data-driven method is effective in decreasing the wall shear stress and disturbance energy at the objective location, and this damping is sustained downstream of the objective location. However, further downstream, the fluctuations grow again reaching amplitudes similar to those in the uncontrolled case.

The 30 Year Search for the Compact Object in SN 1987A
- 2018
-
Ingår i: Astrophysical Journal. - : Institute of Physics Publishing (IOPP). - 0004-637X .- 1538-4357. ; 864:2

Tidskriftsartikel (refereegranskat)abstract
- Despite more than 30 years of searching, the compact object in Supernova (SN) 1987A has not yet been detected. We present new limits on the compact object in SN 1987A using millimeter, near-infrared, optical, ultraviolet, and X-ray observations from ALMA, VLT, HST, and Chandra. The limits are approximately 0.1 mJy (0.1 x 10(-26) erg s(-1) cm(-2) Hz(-1)) at 213 GHz, 1 L-circle dot (6 x 10(-29) erg s(-1) cm(-2) Hz(-1)) in the optical if our line of sight is free of ejecta dust, and 10(36) erg s(-1) (2 x 10(-30) erg s(-1) cm(-2) Hz(-1) ) in 2-10 keV X-rays. Our X-ray limits are an order of magnitude less constraining than previous limits because we use a more realistic ejecta absorption model based on three-dimensional neutrino-driven SN explosion models. The allowed bolometric luminosity of the compact object is 22 L-circle dot if our line of sight is free of ejecta dust, or 138L(circle dot) if dust-obscured. Depending on assumptions, these values limit the effective temperature of a neutron star (NS) to <4-8 MK and do not exclude models, which typically are in the range 3-4 MK. For the simplest accretion model, the accretion rate for an efficiency 77 is limited to <10(-11) eta(-1) M-circle dot yr(-1), which excludes most predictions. For pulsar activity modeled by a rotating magnetic dipole in vacuum, the limit on the magnetic field strength (B) for a given spin period (P) is B less than or similar to 10(14) P-2 G s(-2), which firmly excludes pulsars comparable to the Crab. By combining information about radiation reprocessing and geometry, we infer that the compact object is a dust-obscured thermally emitting NS, which may appear as a region of higher-temperature ejecta dust emission.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Den årliga trålundersökningen längs den västsvenska skärgården sträcker sig från utsjöbanken Fladen i norra Kattegatt till Singlefjorden vid norska gränsen. Undersökningen har utförts årligen sedan 2001 med syfte är att inventera artsammansättningen och rekryteringen hos fisk i allmänhet, samt förekomst av stor torsk i synnerhet. Kusttrålundersökningen tillför också grundläggande data avseende indikatorer för kustfiskarter inom ramen för arbetet med Havsmiljödirektivet. År 2021 utfördes undersökningen under 9 dagar mellan den 30 augusti och 9 september. Totalt trålades 34 stationer varav 8 låg i utsjön och 26 vid kusten. Torskfångsten är fortsatt låg, med en storleksfördelning i favör till liten och ung torsk <18 cm. Endast fem torskar om minst 40 cm fångades. Vitling är fortsatt den vanligaste arten, men har minskat kraftigt i utsjön.

The Impact of Nonequilibrium Conditions in Lung Surfactant : Structure and Composition Gradients in Multilamellar Films

Tidskriftsartikel (refereegranskat)abstract
- The lipid-protein mixture that covers the lung alveoli, lung surfactant, ensures mechanical robustness and controls gas transport during breathing. Lung surfactant is located at an interface between water-rich tissue and humid, but not fully saturated, air. The resulting humidity difference places the lung surfactant film out of thermodynamic equilibrium, which triggers the buildup of a water gradient. Here, we present a millifluidic method to assemble multilamellar interfacial films from vesicular dispersions of a clinical lung surfactant extract used in replacement therapy. Using small-angle X-ray scattering, infrared, Raman, and optical microscopies, we show that the interfacial film consists of several coexisting lamellar phases displaying a substantial variation in water swelling. This complex phase behavior contrasts to observations made under equilibrium conditions. We demonstrate that this disparity stems from additional lipid and protein gradients originating from differences in their transport properties. Supplementing the extract with cholesterol, to levels similar to the endogenous lung surfactant, dispels this complexity. We observed a homogeneous multilayer structure consisting of a single lamellar phase exhibiting negligible variations in swelling in the water gradient. Our results demonstrate the necessity of considering nonequilibrium thermodynamic conditions to study the structure of lung surfactant multilayer films, which is not accessible in bulk or monolayer studies. Our reconstitution methodology also opens avenues for lung surfactant pharmaceuticals and the understanding of composition, structure, and property relationships at biological air-liquid interfaces.

Rapport (refereegranskat)abstract
- Klimatförändringar utgör en bred palett av risker för kulturmiljö och landskap,inklusive de kulturhistoriska lämningar som har en nära eller direkt kopplingtill transportinfrastruktur. I detta projekt tittade vi på ett antal av dessa riskeri syfte att hjälpa Trafikverket att utveckla tjänster för bättre förutsägelse ochhantering av riskerna i anslutning till vägar och banor. Forskningen inleddesgenom en översikt av befintliga offentliga publikationer om klimatförändringenshot, risker, metoder, anpassningsåtgärder och kulturmiljö. Detta följdesav en undersökning av upplevelsen av dessa frågor bland offentligt anställdaexperter som medverkar i planeringen. Geografiska informationssystem (GIS)användes för att identifiera kulturhistoriska lämningar som är klimatologisktriskutsatta sig i riskzonen för tre undersökningsområden, följt av fältbesökför att bedöma tillförlitligheten i GIS-resultaten. Analysen visade att en enkelGIS-analys kan vara till hjälp för att identifiera riskutsatta platser, men ocksåatt fältarbete kan medverka till att identifiera ytterligare risker men också problemmed noggrannheten i underliggande datamaterial. Projektet tillhandahållerockså grundläggande statistik om i vilken utsträckning olika typer avkulturhistoriska lämningar på nationell nivå riskerar att hotas enligt nuvarandeklimatförändringsmodeller. Projektet genomförde också fallstudier av 1) vägsaltetsrisker för milstolpar och andra arkeologiska företeelser i anslutning tillvägar, och 2) de historiska kartornas potential att användas för att identifierariskutsatta områden vid framtida klimatförändringar. Slutligen diskuteras konsekvensernaav dessa resultat för prioriteringar av klimatanpassningsaktivitetersamt presenterar förslag på metoder och modeller för att identifiera transportinfrastrukturenskulturmiljöer som är hotas av klimatförändringar.

- BACKGROUND & AIMS: Early-onset colorectal cancer (CRC, in persons younger than 50 years old) is increasing in incidence; yet, in the absence of a family history of CRC, this population lacks harmonized recommendations for prevention. We aimed to determine whether a polygenic risk score (PRS) developed from 95 CRC-associated common genetic risk variants was associated with risk for early-onset CRC.METHODS: We studied risk for CRC associated with a weighted PRS in 12,197 participants younger than 50 years old vs 95,865 participants 50 years or older. PRS was calculated based on single nucleotide polymorphisms associated with CRC in a large-scale genome-wide association study as of January 2019. Participants were pooled from 3 large consortia that provided clinical and genotyping data: the Colon Cancer Family Registry, the Colorectal Transdisciplinary Study, and the Genetics and Epidemiology of Colorectal Cancer Consortium and were all of genetically defined European descent. Findings were replicated in an independent cohort of 72,573 participants.RESULTS: Overall associations with CRC per standard deviation of PRS were significant for early-onset cancer, and were stronger compared with late-onset cancer (P for interaction = .01); when we compared the highest PRS quartile with the lowest, risk increased 3.7-fold for early-onset CRC (95% CI 3.28-4.24) vs 2.9-fold for late-onset CRC (95% CI 2.80-3.04). This association was strongest for participants without a first-degree family history of CRC (P for interaction = 5.61 x 10(-5)). When we compared the highest with the lowest quartiles in this group, risk increased 4.3-fold for early-onset CRC (95% CI 3.61-5.01) vs 2.9-fold for late-onset CRC (95% CI 2.70-3.00). Sensitivity analyses were consistent with these findings.CONCLUSIONS: In an analysis of associations with CRC per standard deviation of PRS, we found the cumulative burden of CRC-associated common genetic variants to associate with early-onset cancer, and to be more strongly associated with early-onset than late-onset cancer, particularly in the absence of CRC family history. Analyses of PRS, along with environmental and lifestyle risk factors, might identify younger individuals who would benefit from preventive measures.

JWST NIRCam Observations of SN 1987A : Spitzer Comparison and Spectral Decomposition
- 2023
-
Ingår i: Astrophysical Journal. - : American Astronomical Society. - 0004-637X .- 1538-4357. ; 959:2

Tidskriftsartikel (refereegranskat)abstract
- JWST Near Infrared Camera (NIRCam) observations at 1.5–4.5 μm have provided broadband and narrowband imaging of the evolving remnant of SN 1987A with unparalleled sensitivity and spatial resolution. Comparing with previous marginally spatially resolved Spitzer Infrared Array Camera (IRAC) observations from 2004 to 2019 confirms that the emission arises from the circumstellar equatorial ring (ER), and the current brightness at 3.6 and 4.5 μm was accurately predicted by extrapolation of the declining brightness tracked by IRAC. Despite the regular light curve, the NIRCam observations clearly reveal that much of this emission is from a newly developing outer portion of the ER. Spots in the outer ER tend to lie at position angles in between the well-known ER hotspots. We show that the bulk of the emission in the field can be represented by five standard spectral energy distributions, each with a distinct origin and spatial distribution. This spectral decomposition provides a powerful technique for distinguishing overlapping emission from the circumstellar medium and the supernova ejecta, excited by the forward and reverse shocks, respectively.

Burnout among school teachers : quantitative and qualitative results from a follow-up study in southern Sweden
- 2019
-
Ingår i: BMC Public Health. - : BioMed Central. - 1471-2458. ; 19
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Teachers are at high risk of stress-related disorders. This longitudinal study aimed to (a) identify which occupational, sociodemographic and life-style factors and self-efficacy at baseline that were of importance for burnout, (b) explore associations between changes in the studied factors versus changes in burnout, and (c) by interviews increase the understanding of perceived job demands among teachers.Methods: A cohort of 310 Swedish teachers in school-years 4–9 responded to a questionnaire of occupational, sociodemographic and life-style factors, self-efficacy and burnout, at baseline and at follow-up (mean 30 months later). A combined measure with four levels of burnout was crafted, based on exhaustion, cynicism and professional efficacy (Maslach Burnout Inventory-General Survey). Quantitative data were analysed with multiple ordinal regression, and qualitative data were analysed with content analysis of interview responses from a subgroup of the teachers (n = 81).Results: The occurrence of high burnout (level 2 and 3 combined) were similar at baseline and follow-up (14% vs. 15%). However, many teachers fluctuated between the levels of burnout (28% increased and 24% decreased). Burnout at baseline was of importance for change of work or being off duty at follow up. In the multi-exposure model, low self-efficacy [OR 0.42; CI 0.26–0.68] and high job demands [OR 1.97; CI 1.02–3.8] were the strongest explanatory variables. Low self-efficacy remained as the strongest explanatory factor after adjustment for burnout at baseline. Increased job demands during follow-up was associated with an increased level of burnout [OR 3.41; CI 1.73–6.69], whereas increased decision latitude was associated with a decreased level of burnout [OR 0.51; CI 0.30–0.87]. Two major categories of demands emerged in the qualitative analysis; i.e. too high workload and a sense of inadequacy.Conclusions: A substantial proportion of teachers showed signs of burnout at both occasions. Low self-efficacy and high job demands was of importance for burnout, and changes in burnout was further associated with changes in decision latitude. The results points to the need of actions on individual, organizational and a societal levels.

Miljökvalitetsmålen 2016 : Årlig uppföljning av miljökvalitetsmålen
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- I Blekinge bedöms inte något miljökvalitetsmål vara möjligt att nå till år 2020. För att kunna lämna över ett hållbart samhälle till nästa generation krävs förebyggande arbete, ef?????????????????r. Ambitionerna måste öka och miljöfrågorna prioriteras högre på den politiska agendan.De mål som rör biologisk mångfald och bevarande av kulturmiljö följer enneutral eller negativ trend. I odlingslandskapet leder färre lantbrukare ochbrist på betesdjur till igenväxning av hagmarker. Livsmiljöer försvinner och????????????????????????????????????????,främst möte insekter.För att god ekologisk status ska uppnås i vattendragen behövs ny vattenlagstiftning och mer resurser för tillsyn. I Blekinges kustvatten är övergödning ett stort miljöproblem och det krävs kraftfulla åtgärder för att minska näringsläckaget. Arbetet med vattenförsörjningsplaner behöver fortsätta för att trygga framtida dricksvattenförsörjning. De senaste årens fynd av PFAS i dricksvatten visar på vikten av att skydda vattentäkter, genomföra riskbedömningar och undersöka förekomst av föroreningar.Obalans mellan den tätbefolkade kusten och den glesbyggda landsbygden är en utmaning i länet. Byggandet vid kusten ställer krav på en hänsynsfull bebyggelseutveckling som tydligt beaktar miljökvalitetsmålen.Internationella överenskommelser om kemikalier och minskade utsläpp till luft och vatten är nödvändigt för att uppnå uppsatta mål. Dessutom behövs en omställning till ett samhälle som baseras på förnybar energi. För att skapa en hållbar framtid måste vi förändra vår livsstil och vår attityd till konsumtion. Lokala och regionala åtgärder såsom arbete för en giftfri förskola och minskade utsläpp av mikroplaster är steg i rätt riktning.Minskad biologisk mångfald påverkar tillsammans med klimatförändringar, övergödning och miljögifter många av de ekosystemtjänster som vi är beroende av för mänsklig välfärd och en hållbar samhällsutveckling. Det pågår insatser som förbättrar tillståndet i miljön, men det går för långsamt. Det krävs mer resurser och modiga politiska beslut för att möjliggöra en hållbar framtid, den framtid som vi är skyldiga våra barn!
