- 2014
-
In: Animal Movement Across Scales. - : Oxford University Press. - 9780199677184 ; , s. 259-267
-
Book chapter (peer-reviewed)abstract
- This chapter aims at synthesizing the knowledge presented in the chapters of the book’s three sections by addressing evolutionary compromises, dispersal, gene flow, and assisted movements. How climate change and other environmental changes at different scales may affect animal movement, migration, and dispersal in the future are also summarized here. Moreover, how the different senses are utilized for navigation and orientation and how these may lead to different movement and migration patterns are also discussed. Finally, how the recent technical revolution has affected animal movement research is addressed and the view on future perspectives of animal movement research is also provided.

Curettage and electrodessication combined with photodynamic therapy in the treatment of large squamous cell carcinomas in unfit and frail patients
- 2022
-
In: BMJ Case Reports. - : BMJ. - 1757-790X. ; 15:6
-
Journal article (peer-reviewed)abstract
- A Caucasian female patient in her 90s was referred to the department of plastic and reconstructive surgery for surgical removal of a large invasive squamous cell carcinoma on the anterior chest wall. A skin biopsy prior to the referral indicated that the tumour was moderately differentiated. The patient suffered from severe congestive heart failure with a mechanical valve prosthesis and atrial fibrillation, and was therefore treated with anticoagulants. Hence, a surgical procedure would be hazardous. Therefore, other treatment options were considered. The principal aim was to reduce the amount of tumour tissue to an appropriate size suitable for later excision with primary wound closure. After interdisciplinary discussions, curettage and electrodessication combined with photodynamic therapy was judged the best alternative treatment in this case. At the 1.5 years follow-up after the intervention there was no indication for further surgery. The patient was at that stage content with the treatment and its outcome.

Cost and health outcome of primary percutaneous coronary intervention versus thrombolysis in acute ST-segment elevation myocardial infarction-Results of the Swedish Early Decision reperfusion Study (SWEDES) trial.
- 2010

In: American heart journal. - : Elsevier BV. - 1097-6744 .- 0002-8703. ; 160:2, s. 322-8

Journal article (peer-reviewed)abstract
- BACKGROUND: In ST-elevation myocardial infarction, primary percutaneous coronary intervention (PCI) has a superior clinical outcome, but it may increase costs in comparison to thrombolysis. The aim of the study was to compare costs, clinical outcome, and quality-adjusted survival between primary PCI and thrombolysis. METHODS: Patients with ST-elevation myocardial infarction were randomized to primary PCI with adjunctive enoxaparin and abciximab (n = 101), or to enoxaparin followed by reteplase (n = 104). Data on the use of health care resources, work loss, and health-related quality of life were collected during a 1-year period. Cost-effectiveness was determined by comparing costs and quality-adjusted survival. The joint distribution of incremental costs and quality-adjusted survival was analyzed using a nonparametric bootstrap approach. RESULTS: Clinical outcome did not differ significantly between the groups. Compared with the group treated with thrombolysis, the cost of interventions was higher in the PCI-treated group ($4,602 vs $3,807; P = .047), as well as the cost of drugs ($1,309 vs $1,202; P = .001), whereas the cost of hospitalization was lower ($7,344 vs $9,278; P = .025). The cost of investigations, outpatient care, and loss of production did not differ significantly between the 2 treatment arms. Total cost and quality-adjusted survival were $25,315 and 0.759 vs $27,819 and 0.728 (both not significant) for the primary PCI and thrombolysis groups, respectively. Based on the 1-year follow-up, bootstrap analysis revealed that in 80%, 88%, and 89% of the replications, the cost per health outcome gained for PCI will be <$0, $50,000, and $100,000 respectively. CONCLUSION: In a 1-year perspective, there was a tendency toward lower costs and better health outcome after primary PCI, resulting in costs for PCI in comparison to thrombolysis that will be below the conventional threshold for cost-effectiveness in 88% of bootstrap replications.

Centrality and transverse momentum dependence of collective flow in 158 A GeV Pb+Pb collisions measured via inclusive photons
- 2005
-
In: Nuclear Physics, Section A. - : Elsevier BV. - 0375-9474. ; 762:1-2, s. 129-146
-
Journal article (peer-reviewed)abstract
- Directed and elliptic flow of inclusive photons near mid-rapidity in 158 A GeV Pb + Pb collisions has been studied. The data have been obtained with the photon spectrometer LEDA of the WA98 experiment at the CERN SPS. The flow strength has been measured for various centralities as a function of p(T) and rapidity over 0. 18 < p(T) < 1.5 GeV/c and 2.3 < y < 2.9. The angular anisotropy has been studied relative to an event plane obtained in the target fragmentation region that shows the elliptic flow to be in-plane. The elliptic flow has also been studied using two-particle correlations and shown to give similar results. A small directed flow component is observed. Both the directed and elliptic flow strengths increase with p(T). The photon flow results are used to estimate the corresponding neutral pion flow.

Centrality dependence of charged-neutral particle fluctuations in 158A (GeVPb)-Pb-208+Pb-208 collisions
- 2003

In: Physical Review C (Nuclear Physics). - 0556-2813. ; 67:4
-
Journal article (peer-reviewed)abstract
- Results on the study of localized fluctuations in the multiplicity of charged particles and photons produced in 158A GeV/c Pb+Pb collisions are presented for varying centralities. The charged versus neutral particle multiplicity correlations in common phase space regions of varying azimuthal sizes are analyzed by two different methods. Various types of mixed events are constructed to probe fluctuations arising from different sources. The measured results are compared to those from simulations and from mixed events. The comparison indicates the presence of nonstatistical fluctuations in both the charged particle and photon multiplicities in limited azimuthal regions. However, no correlated charged-neutral fluctuations, a possible signature of formation of disoriented chiral condensates, are observed. An upper limit on the production of disoriented chiral condensates is set.

Event-by-event fluctuations in particle multiplicities and transverse energy produced in 158A GeVPb plus Pb collisions
- 2002

In: Physical Review C (Nuclear Physics). - 0556-2813. ; 65:5
-
Journal article (peer-reviewed)abstract
- Event-by-event fluctuations in the multiplicities of charged particles and photons, and the total transverse energy in 158A GeV Pb+Pb collisions are studied for a wide range of centralities. For narrow centrality bins the multiplicity and transverse energy distributions are found to be near perfect Gaussians. The effect of detector acceptance on the multiplicity fluctuations has been studied and demonstrated to follow statistical considerations. The centrality dependence of the charged particle multiplicity fluctuations in the measured data has been found to agree reasonably well with those obtained from a participant model. However, for photons the multiplicity fluctuations have been found to be lower compared to those obtained from a participant model. The multiplicity and transverse energy fluctuations have also been compared to those obtained from the VENUS event generator.

Journal article (peer-reviewed)abstract
- The azimuthal distributions of photons and charged particles with respect to the event plane are investigated as a function of centrality in Pb-208 + Pb-208 collisions at 158 (.) A GeV/c in the WA98 experiment at the CERN SPS. The anisotropy of the azimuthal distributions is characterized using a Fourier analysis. For both the photon and charged particle distributions the first two Fourier coefficients are observed to decrease with increasing centrality. The observed anisotropies of the photon distributions compare well with the expectations from the charged particle measurements for all centralities.

Journal article (peer-reviewed)abstract
- Charged particles and photons have been measured in central Pb + Pb collisions at 158 A GeV in a common (eta-phi)-phase space region in the WA98 experiment at the CERN SPS. The measured distributions have been analyzed to quantify the frequency with which phase space regions of varying sizes have either small or large neutral pion fraction. The measured results are compared with VENUS model simulated events and with mixed events. Events with both large and small charged-neutral fluctuations are observed to occur more frequently than expected statistically, as deduced from mixed events, or as predicted by model simulations, with the difference becoming more prominent with decreasing size of the A Delta eta-Delta phi region.

Pion freeze-out time in Pb plus Pb collisions at 158 AGeV/c studied via pi(-)/pi(+) and K-/K+ ratios
- 2006
-
In: European Physical Journal C. Particles and Fields. - : Springer Science and Business Media LLC. - 1434-6044. ; 48:2, s. 343-352
-
Journal article (peer-reviewed)abstract
- The effect of the final state Coulomb interaction on particles produced in Pb + Pb collisions at 158AGeV/c has been investigated in the WA98 experiment through the study of the pi(-)/pi(+) and K-/K+ ratios measured as a function of T-m- (m)0. While the ratio for kaons shows no significant T-m dependence, the pi(-)/pi(+) ratio is enhanced at small T-m - (m)0 values with an enhancement that increases with centrality. A silicon pad detector located near the target is used to estimate the contribution of hyperon decays to the pi(-)/pi(+) ratio. The comparison of results with predictions of the RQMD model in which the Coulomb interaction has been incorporated allows to place constraints on the time of the pion freeze-out.

Suppression of high-p(T) neutral pion production in central Pb+Pb collisions at root s(NN)=17.3 GeV relative to p+C and p+Pb collisions
- 2008
-
In: Physical Review Letters. - 1079-7114. ; 100:24
-
Journal article (peer-reviewed)abstract
- Neutral pion transverse momentum spectra were measured in p+C and p+Pb collisions at root s(NN) = 17.4 GeV at midrapidity (2.3 less than or similar to eta(lab)less than or similar to 3.0) over the range 0.7 less than or similar to p(T)less than or similar to 3.5 GeV/c. The spectra are compared to pi(0) spectra measured in Pb+Pb collisions at root s(NN) = 17.3 GeV in the same experiment. For a wide range of Pb+Pb centralities (N-part less than or similar to 300), the yield of pi(0)'s with p(T)greater than or similar to 2 GeV/c is larger than or consistent with the p+C or p+Pb yields scaled with the number of nucleon-nucleon collisions (N-coll), while for central Pb+Pb collisions with N-part greater than or similar to 350, the pi(0) yield is suppressed.

Transverse mass distributions of neutral pions from Pb-208-induced reactions at 158 center dot A GeV
- 2002
-
In: European Physical Journal C. Particles and Fields. - : Springer Science and Business Media LLC. - 1434-6044. ; 23:2, s. 225-236
-
Journal article (peer-reviewed)abstract
- Results on transverse mass spectra of neutral pious measured at central rapidity are presented for impact parameter selected 158-A GeV Pb + Pb-1 and Pb + Nb collisions. The distributions cover the range 0.5 GeV/c(2) less than or equal to MT - Mo less than or equal to 4 GeV/c(2). The change of the spectral shape and the multiplicity with centrality is studied in detail. In going from p+p to semi-peripheral Pb+Pb collisions there is a nuclear enhancement increasing with transverse mass similar to the well known Cronin effect, while for very central collisions this enhancement appears to be weaker than expected.

Dagfjärilar i naturbetesmarker, kraftledningsgator, på hyggen och skogsbilvägar : betydelse för miljöövervakning
- 2011
-
Reports (other academic/artistic)abstract
- Ett förändrat och intensifierat jordbruk har bland annat lett till att naturbetesmarker och andra gräsmarksbiotoper minskat i odlingslandskapet. Detta har fått till följd att många arter knutna till öppna gräsmarker minskat, däribland fåglar, växter och dagfjärilar. Dagfjärilar svarar snabbt på förändringar både i miljön och klimatet och kan därför vara viktiga indikatorarter för miljöövervakning. I år startar en nationell övervakning av dagfjärilar med hjälp av volontärer och de senaste fem åren har dagfjärilar inventerats i ängs- och betesmarker inom den nationella inventeringen av landskapet (NILS). För att få en rättvisande bild av hur situationen ser ut för dagfjärilar i Sverige kan det vara viktigt att systematiskt inventera olika typer av miljöer, inte enbart ängs- och betesmarker eller känt artrika platser. I den här studien jämför vi artrikedom, individantal och artsammansättning av dagfjärilar (Rophalocera) och bastardsvärmare (Zyganidaea) i naturbetesmarker och tre typer av öppna biotoper i skogslandskapet; hyggen, kraftledningsgator och skogsbilvägar. Vi delar också in fjärilarna efter val av värdväxt och flygtid på säsongen för att se om det finns några skillnader mellan biotoperna vad gäller art- och individrikedom inom dessa grupper. Vi undersöker hur mängden skog och betesmark inom det omgivande landskapet påverkar dagfjärilsfaunan på de olika platserna och hur många inventeringstillfällen (3, 5 eller 7) som krävs för att få tillförlitliga data på artrikedomen på en plats. Våra resultat visar att artsammansättningen av fjärilar skiljer sig mellan biotoperna och att alla bidrar med unika arter och således kompletterar varandra. Kraftledningsgatorhade både fler fjärilsarter och individer än de övriga biotoperna och hyggen och skogsbilvägar var lika art- och individrika som betesmarkerna. Det är därför viktigt att övervaka flera typer av miljöer och även skogsbiotoper inom framtida dagfjärilsövervakning. Eftersom alla tre skogsbiotoperna hyser en stor mångfald av fjärilar kan det vara värt att anpassa skötseln av dessa miljöer för att gynna fjärilar. I kraftledningsgator och skogsbilvägar som är relativt beständiga miljöer och som redan idag sköts med ett visst intervall är detta fullt möjligt. Betydelsen av antal inventeringstillfällen beror på vilken frågeställning man har. Vill man jämföra artrikedomen i olika miljöer eller studera förändring i artrikedom mellan år kan det kanske räcka med tre besök, men vill man ha en mer heltäckande bild av artrikedomen på en plats kan det sju eller fler besök spridda över säsongen
