OBJECTIVE: We review the existing research on environmentally sustainable surgical practices to enable SAO to advocate for improved environmental sustainability in operating rooms across the country. SUMMARY OF BACKGROUND DATA: Climate change refers to the impact of greenhouse gases emitted as a byproduct of human activities, trapped within our atmosphere and resulting in hotter and more variable
I discuss the dilution of responsibility of action and the idea of a symmetrical relationship between artefacts and humans. In doing so, I argue that meaning making is an activity unilaterally performed by agents, leading to an asymmetrical relationship between agents and artefacts. Therefore, the study of the one who is responsible for the action, the meaning-maker (with the capability to act) is
In the summer of 1922, fieldwork was conducted in the Tornedalen district of northern Sweden, in the immediate vicinity of the border with Finland. Three young men travelled together through the district on a motorcycle, documenting archaic buildings and villages in words and images. This documentation effort was part of a larger endeavour to survey and collect all the different aspects of what wa
During recent years, many sites with sediments pre-dating the Last Glacial Maximum have been identified in formerly glaciated areas. As more and better dates are presented from these sites, the dynamic behaviour of the Scandinavian Ice Sheet is becoming increasingly clear. In this study, we revisited the site Skorgenes in western Norway. Here, sediments from two ice-free periods are found below an
This paper reports on a retrospective analysis of hospital-based healthcare costs associated with the management of chronic obstructive pulmonary disease (COPD). During the second half of 2001, Simrishamn Hospital, Sweden, implemented a structured Disease Management Programme (DMP) for COPD and a total of 784 patients with COPD, enrolled in the DMP, were included in the analysis. The goal was to r
Växtätare kan påverka ekosystemprocesser, dels genom långsiktiga förändringar av växtsamhällets sammansättning, men också på kortare sikt genom derasmatspjälkning av organiskt material som cyklas genom markens nedbryderorganismer och tillbaka till de primära producenterna. Särskilt störreväxtätare har studerats i stor utsträckning, men i vissa ekosystem som skogar kan de mindre ryggradslösa växtätHerbivory can influence ecosystem processes, partly through long-term changes of the plant community compositions, but also more rapidly through the herbivores’ digestive alteration of the organic matter that is cycled through the soil and back to the primary producers. In the Subarctic mountain birch (Betula pubescens ssp. czerepanovii) forest (SMBF) in Northern Fennoscandia, outbreaks by the geo
Background: Computed tomography (CT) of the brain is performed with high local doses due to high demands on low contrast resolution. Advanced algorithms for noise reduction might be able to preserve critical image information when reducing radiation dose.PurposeTo evaluate the effect of advanced noise filtering on image quality in brain CT acquired with reduced radiation dose. Material and Method
We present the results of 3D high-resolution calculations of the last inspiral stages and the final coalescence of neutron star binary systems. The equations of hydrodynamics are solved using the smoothed particle hydrodynamics method with up to 106 particles. Using Newtonian gravity, but adding the forces emerging from the emission of gravitational waves, we focus on the impact of microphysics on
This doctoral dissertation presents the development and digital hardware realization of cardiac event detectors. Implantable medical appliances, as the cardiac pacemaker, have progressed from a life sustaining device to a device that considerably improves life quality for all ages. The number of electronic devices and household appliances in everyday live has an ongoing exponential growth. The
The aerobic biodegradation of toxic organic volatile contaminants is always limited by the low aqueous solubility of O2. Therefore, intensive bubbling or surface aeration is required to supply the bacterial community with sufficient O2 to carry out pollutant mineralization. This can cause the hazardous volatilization of toxic volatile contaminants. Photosynthetic oxygenation overcomes these limita
Cryptic pigmentation of prey is often thought to evolve in response to predator-mediated selection, but pigmentation traits can also be plastic, and change with respect to both abiotic and biotic environmental conditions. In such cases, identifying the presence of, and drivers of trait plasticity is useful for understanding the evolution of crypsis. Previous work suggests that cryptic pigmentation
ELI Beamlines is a rapidly progressing pillar of the pan-European Extreme Light Infrastructure (ELI) project focusing on the development and deployment of science driven by high-power lasers for user operations. This work reports the results of a commissioning run of a water-jet plasma X-ray source driven by the L1 Allegra laser, outlining the current capabilities and future potential of the syste
One of the points on which researchers agree is the centrality of autonomy to professionalism. Moreover, a common conclusion in the studies of professions is that the profound changes in society over the last fifty years have threatened the autonomy and changed the archetype of professionalism. This paper contributes to the research on changes and continuities, challenges and opportunities for pro
In this work, selective area growth has been used for the realization of InP based photonic integrated circuits (PICs). To predict the strain, thickness and bandgap energy variations over large and high-density multifunctional arrays, it is necessary to precisely design the shapes and positions of the dielectric masks by computational modeling. To address the mask layout density and complexity in
Objectives Investigating men's perceived lifetime risk of prostate cancer. Design Survey-based study to men invited for prostate-specific antigen (PSA) screening in the GÖTEBORG-2 trial between September 2015 and June 2020. Setting 38 775 men in the Gothenburg area, Sweden, were invited for PSA-Testing and participated in a survey. Participants 17 980 men participated in PSA-Testing, of whom 13 18
Lösningen av de pågående klimat- och energikriserna kräver en radikal omvandling av energisystemet, där hållbarhet, inga koldioxidutsläpp och energieffektivitet bör spela en avgörande roll.Denna revolution bör sträcka sig till alla delar av energisystemet, inklusive sektorn för uppvärmning och kylning av byggnader, som står för en tredjedel av Europas slutliga energibehov och på den europeiska konThe solution of the undergoing climate and energy crises requires a radical transformation of the energy system, in which sustainability, no carbon emissions and energy efficiency ought to play a paramount role. This revolution should extend to all areas of the energy system, including the space heating and cooling sector, which accounts for a third of the European final energy demand and, in the
The European Green Deal recognises the importance of addressing the environmental challenges posed by agriculture to meet the global biodiversity and climate agendas. Environmental policymaking is needed to drive and speed up sustainability transitions in agriculture because the environmental consequences of agricultural activities are not generally reflected in production costs and lead to market
