Nationell luftövervakning : Sakrapport med data från övervakning inom Programområde Luft t. o. m. 2021
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Naturvårdsverket ansvarar för den nationella luftövervakningen i bakgrundsmiljö. I rapporten redovisas resultat från verksamheten inom Programområde Luft avseende mätningar (genomförda av IVL Svenska Miljöinstitutet (IVL),Institutionen för Miljövetenskap vid Stockholms universitet (SU), Institutionen för Mark och Miljö vid Sveriges lantbruksuniversitet (SLU), Chalmers tekniska högskola och Sveriges meteorologiska och hydrologiska institut (SMHI) till och med 2021 samt regionala modellberäkningar (utförda av SMHI) till och med 2020. För flertalet av de luftföroreningskomponenter som övervakas inom den nationella miljöövervakningen har det, sedan mätningarna startade för mellan 20 och 45 år sedan, generellt skett en avsevärd förbättring avseende såväl halter i luft som deposition i bakgrundsmiljö.Utvecklingen har dock varierat i något olika utsträckning beroende på komponenter och lokalisering i landet. Föroreningsbelastningen är oftast lägre ju längre norrut i landet man kommer.För de flesta ämnen som det finns miljökvalitetsnormer (MKN) respektive miljömål för ligger halterna avsevärt lägre än angivna gräns- och målvärden. Halterna av marknära ozon överskrider i dagsläget MKN för hälsa vid ett flertal mätstationer i södra Sverige.För såväl partiklar (i form av PM2,5) och bensen (i urban bakgrund) är risken låg att haltnivåer överstiger miljömålens preciseringar.

- For centuries, domestic horses have represented an important means of transport and served as working and companion animals. Although their role in transportation is less important today, many horse breeds are still subject to intense selection based on their pattern of locomotion. A striking example of such a selected trait is the ability of a horse to perform additional gaits other than the common walk, trot and gallop. Those could be four-beat ambling gaits, which are particularly smooth and comfortable for the rider, or pace, used mainly in racing. Gaited horse breeds occur around the globe, suggesting that gaitedness is an old trait, selected for in many breeds. A recent study discovered that a nonsense mutation in DMRT3 has a major impact on gaitedness in horses and is present at a high frequency in gaited breeds and in horses bred for harness racing. Here, we report a study of the worldwide distribution of this mutation. We genotyped 4396 horses representing 141 horse breeds for the DMRT3 stop mutation. More than half (2749) of these horses also were genotyped for a SNP situated 32kb upstream of the DMRT3 nonsense mutation because these two SNPs are in very strong linkage disequilibrium. We show that the DMRT3 mutation is present in 68 of the 141 genotyped horse breeds at a frequency ranging from 1% to 100%. We also show that the mutation is not limited to a geographical area, but is found worldwide. The breeds with a high frequency of the stop mutation (>50%) are either classified as gaited or bred for harness racing.

Determinants of morbidity and mortality following emergency abdominal surgery in children in low-income and middle-income countries
- 2016
-
Ingår i: BMJ Global Health. - : BMJ Publishing Group Ltd. - 2059-7908. ; 1:4

Tidskriftsartikel (refereegranskat)abstract
- Background: Child health is a key priority on the global health agenda, yet the provision of essential and emergency surgery in children is patchy in resource-poor regions. This study was aimed to determine the mortality risk for emergency abdominal paediatric surgery in low-income countries globally.Methods: Multicentre, international, prospective, cohort study. Self-selected surgical units performing emergency abdominal surgery submitted prespecified data for consecutive children aged <16 years during a 2-week period between July and December 2014. The United Nation's Human Development Index (HDI) was used to stratify countries. The main outcome measure was 30-day postoperative mortality, analysed by multilevel logistic regression.Results: This study included 1409 patients from 253 centres in 43 countries; 282 children were under 2 years of age. Among them, 265 (18.8%) were from low-HDI, 450 (31.9%) from middle-HDI and 694 (49.3%) from high-HDI countries. The most common operations performed were appendectomy, small bowel resection, pyloromyotomy and correction of intussusception. After adjustment for patient and hospital risk factors, child mortality at 30 days was significantly higher in low-HDI (adjusted OR 7.14 (95% CI 2.52 to 20.23), p<0.001) and middle-HDI (4.42 (1.44 to 13.56), p=0.009) countries compared with high-HDI countries, translating to 40 excess deaths per 1000 procedures performed.Conclusions: Adjusted mortality in children following emergency abdominal surgery may be as high as 7 times greater in low-HDI and middle-HDI countries compared with high-HDI countries. Effective provision of emergency essential surgery should be a key priority for global child health agendas.

Maximum levels of cross-contamination for 24 antimicrobial active substances in non-target feed. Part 2: Aminoglycosides/aminocyclitols: apramycin, paromomycin, neomycin and spectinomycin
- 2021
-
Ingår i: EFSA Journal. - : Wiley. - 1831-4732. ; 19:10

Tidskriftsartikel (refereegranskat)abstract
- The specific concentrations of apramycin, paromomycin, neomycin and spectinomycin in non-target feed for food-producing animals, below which there would not be an effect on the emergence of, and/or selection for, resistance in bacteria relevant for human and animal health, as well as the specific antimicrobial concentrations in feed which have an effect in terms of growth promotion/increased yield, were assessed by EFSA in collaboration with EMA. Details of the methodology used for this assessment, associated data gaps and uncertainties, are presented in a separate document. To address antimicrobial resistance, the Feed Antimicrobial Resistance Selection Concentration (FARSC) model developed specifically for the assessment was applied. However, due to the lack of data on the parameters required to calculate the FARSC for these antimicrobials, it was not possible to conclude the assessment until further experimental data become available. To address growth promotion, data from scientific publications obtained from an extensive literature review were used. Levels in feed that showed to have an effect on growth promotion/increased yield were reported for apramycin and neomycin, whilst for paromomycin and spectinomycin, no suitable data for the assessment were available. It was recommended to carry out studies to generate the data that are required to fill the gaps which prevented the calculation of the FARSC for these four antimicrobials.

PARTIspace. WP2 – National Contexts Comparative Report UNIBO, Italy UGOT, Sweden
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The PARTISPACE study aims at undertaking a comparative analysis of youth participation or their involvement and engagement in decisions 'which concern them and, in general, the life of their communities' (European Commission, 2001a: 8). The central research question of the project is how and where 15- and 30 year-old young people do participate differently across social milieus and youth cultural scenes and across eight European cities (framed by different national welfare, education and youth policies). What styles of participation do they prefer, develop and apply and in what spaces does participation take place? Answers to these questions could improve the understanding of the complexities and contradictions of youth participation – on the side of policy makers as well as on the side of young people – and thereby help empowering young people in participating in society, renovating also concepts, definitions and discourses on what (youth) participation is, could and should be. The eight European cities in which we conduct the study are Bologna (IT), Eskisehir (TK), Frankfurt (DE), Gothenburg (SE), Manchester (UK), Plovdiv (BG), Rennes (FR) and Zurich (CH). They do not represent but secure contrasting contexts of young people’s growing up as well as differing orientations towards Europe. Although embedded in different national and local contexts, these eight cities are comparable in terms of dimension and relevance in the respective country. This ensures a sufficient provision and diversity of participatory settings without being too close to representative national government institutions and umbrella structures.

It's a question of endurance : patients with head and neck cancer experiences of 18F-FDG PET/CT in a fixation mask
- 2017

Tidskriftsartikel (refereegranskat)abstract
- PURPOSE: This study aimed to explore how patients with head and neck cancer experienced undergoing an (18)F-fluoro-deoxy-glucose positrons emissions tomography/computed tomography ((18)F-FDG PET/CT) examination in a fixation mask.METHOD: Interviews were conducted with nine patients with known or suspected head and neck cancer who were scheduled for the examination for the first time. The phenomenological method according to van Manen and his four lifeworld existentials; lived space, lived body, lived time, and lived relation was used to analyse the interviews.RESULTS: The thoughts and feelings of the patients during the PET/CT examination varied, some found it very difficult, while others did not. However, for all the patients, it was an experience that required some form of coping to maintain composure for example distraction.CONCLUSIONS: PET/CT examnation in a fixation mask may be strenuous for some patients. Patients need more detailed information, including suggestions for coping behaviours, prior to the examination, as well as higher level of support during and after the examination. The results of this study may be used to improve patient care and optimize the procedure of PET/CT examination in a fixation mask.

A sentiment-annotated dataset of English causal connectives
- 2020
-
Ingår i: Proceedings of the 14th Linguistic Annotation Workshop. - 9781952148330 ; , s. 24-33
-
Konferensbidrag (refereegranskat)abstract
- This paper investigates the semantic prosody of three causal connectives: due to, owing to and because of in seven varieties of the English language. While research in the domain of English causality exists, we are not aware of studies that would cover the domain of causal connectives in English. Our claim is that connectives such as because of link two arguments, (at least) one of which will include a phrase that contributes to the interpretation of the relation as positive or negative, and hence define the prosody of the connective used. As our results demonstrate, the majority of the prosodies identified are negative for all three connectives; the proportions are stable across the varieties of English studied, and contrary to our expectations, we find no significant differences between the functions of the connectives and discourse preferences. Further, we investigate whether automatizing the sentiment annotation procedure via a simple language-model based classifier is possible. The initial results highlights the complexity of the task and the need for complicated systems, probably aided with other related datasets to achieve reasonable performance.

Annotating Topic Development in Information Seeking Queries
- 2016
-
Ingår i: The LREC 2016 Proceedings. - 9782951740891 ; , s. 1755-1761
-
Konferensbidrag (refereegranskat)abstract
- This paper contributes to the limited body of empirical research in the domain of discourse structure of information seeking queries.We describe the development of an annotation schema for coding topic development in information seeking queries and the initialobservations from a pilot sample of query sessions. The main idea that we explore is the relationship between constant and variablediscourse entities and their role in tracking changes in the topic progression. We argue that the topicalized entities remain stable acrossdevelopment of the discourse and can be identified by a simple mechanism where anaphora resolution is a precursor. We also claim thata corpus annotated in this framework can be used as training data for dialogue management and computational semantics systems.

- The precipitation process during ageing in the Mo-poor alloy Carpenter 455 has been investigated by three-dimensional atom probe (3DAP) and energy-filtered transmission electron microscopy. The ageing treatment was performed at 475 degrees C for 5 min, 25 min, 1 h and 2 h. The precipitation of a mixed Ni-, Ti- and Cu-rich phase was observed after 25 min of ageing. A complete separation between Ni/Ti-rich and Cu-rich regions occurred within 1-2 h of ageing. After 2 h of ageing at 475 degrees C, coarsening of the eta-Ni3Ti precipitates was observed. Moreover, large Ni/Ti-rich and Cu-rich particles were observed in the lath boundaries after 2 h of ageing. The results were compared with the precipitation process in the Mo-rich alloy 1RK91.
