Tidskriftsartikel (refereegranskat)abstract
- Cardiopulmonary diseases are major causes of death worldwide, but currently recommended strategies for diagnosis and prevention may be outdated because of recent changes in risk factor patterns. The Swedish CArdioPulmonarybioImage Study (SCAPIS) combines the use of new imaging technologies, advances in large-scale 'omics' and epidemiological analyses to extensively characterize a Swedish cohort of 30 000 men and women aged between 50 and 64 years. The information obtained will be used to improve risk prediction of cardiopulmonary diseases and optimize the ability to study disease mechanisms. A comprehensive pilot study in 1111 individuals, which was completed in 2012, demonstrated the feasibility and financial and ethical consequences of SCAPIS. Recruitment to the national, multicentre study has recently started.

Plug-in Hybrid Electric Vehicles as Regulating Power Providers - Case Studies of Sweden and Germany
- 2010
-
Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215. ; 38:6, s. 2751-2762
-
Tidskriftsartikel (refereegranskat)abstract
- This study investigates plug-in hybrid electric vehicles (PHEVs) as providers of regulating power in the form of primary, secondary and tertiary frequency control. Previous studies have shown that PHEVs could generate substantial profits while providing ancillary services. This study investigates under what conditions PHEVs can generate revenues using actual market data, i.e. prices and activations of regulating power, from Sweden and Germany from four months in 2008. PHEV market participation is modelled for individual vehicles in a fleet subject to a simulated movement pattern. Costs for infrastructure and vehicle-to-grid equipment are not included in the analysis. The simulation results indicate that maximum average profits generated on the German markets are in the range 30–80 h per vehicle and month whereas the Swedish regulating power markets give no profit.In addition, an analysis is performed to identify strengths, weaknesses, opportunities, and threats (SWOT) of PHEVs as regulating power providers. Based on the simulation results and the SWOT analysis, characteristics for an ideal regulating power market for PHEVs are presented.

Konferensbidrag (refereegranskat)abstract
- This paper assesses the effects of the future European power generation system with strict CO2 emission reduction targets on the planning of cross-border interconnection lines. Results from a techno-economic energy systems model have been used as input to this work, regarding the development of the European power generation system until the year 2050, meeting the EU 2020 CO2 target and a 85% emissions reduction until the year 2050. A simplified UCTE power system model was developed in order to analyze how the cross-border interconnections in continental Europe are affected by the generation plans using an iterative method. The paper also attempts to identify the congestion points and proposes solutions based on nodal price modeling. A cost-benefit analysis (CBA) is used to evaluate the appropriate transmission planning strategy, with the costs being the long-term investment costs and the benefits being both the avoided environmental costs and the total congestion costs. The effects of new investments on the nodal prices are also studied. The results show that the profitability of the investments is influenced by the available production mix and the forecasted CO2 prices. The avoided congestion costs participate rather insignificantly in the CBA, which means that congestions are not relieved, showing that many interconnections are insufficient for nodal pricing market structure.

Tidskriftsartikel (refereegranskat)abstract
- Digital tomosynthesis (DTS) has been used in chest imaging as a low radiation dose alternative to computed tomography (CT). Traditional DTS shows limitations in the spatial resolution in the out-of-plane dimension. As a first indication of whether a dual-plane dual-view (DPDV) DTS data acquisition can yield a fair resolution in all three spatial dimensions, a manual registration between a frontal and a lateral image volume was performed. An anthropomorphic chest phantom was scanned frontally and laterally using a linear DTS acquisition, at 120 kVp. The reconstructed image volumes were resampled and manually co-registered. Expert radiologist delineations of the mediastinal soft tissues enabled calculation of similarity metrics in regard to delineations in a reference CT volume. The fused volume produced the highest total overlap, implying that the fused volume was a more isotropic 3D representation of the examined object than the traditional chest DTS volumes.

Tidskriftsartikel (refereegranskat)abstract
- The present biofuel policies in the European Union primarily stimulate 1st generation biofuels that are produced based on conventional food crops. They may be a distraction fromlignocellulose based 2nd generation biofuels – and also from biomass use for heat and electricity – by keeping farmers’ attention and significant investments focusing on firstgeneration biofuels and the cultivation of conventional food crops as feedstocks. This article presents two strategies that can contribute to the development of 2nd generation biofuels based on lignocellulosic feedstocks. The integration of gasification-based biofuel plants in district heating systems is one option for increasing the energy efficiency and improving the economic competitiveness of such biofuels. Another option, biomass co-firing with coal,generates high-efficiency biomass electricity and reduces CO2 emissions by replacing coal. It also offers a near-term market for lignocellulosic biomass, which can stimulate development of supply systems for biomass also suitable as feedstock for 2nd generation biofuels. Regardless of the long-term priorities of biomass use for energy, the stimulation of lignocellulosic biomass production by development of near term and cost-effective markets isjudged to be a no-regrets strategy for Europe. Strategies that induce a relevant development and exploit existing energy infrastructures in order to reduce risk and reach lower costs, are proposed an attractive complement the present and prospective biofuel policies.

Co-recycling of natural and synthetic carbon materials for a sustainable circular economy
- 2022
-
Ingår i: Journal of Cleaner Production. - : Elsevier BV. - 0959-6526. ; 365
-
Tidskriftsartikel (refereegranskat)abstract
- Circular economy approaches are commonly depicted by two cycles, where the biological cycle is associated with regeneration in the biosphere and the technical cycle with reuse, refurbishment, and recycling to maintain value and maximize material recovery. This work, instead, presents an alternative vision to the management of carbonbased materials that integrates the two cycles and enables the phasing-out of fossil carbon from the material system. The aim is to investigate the benefits and global potential of a co-recycling system, as an alternative to conventional recycling systems that separate biomass-based materials (e.g., wood, paper) from fossil-based materials (e.g., plastics). Thermochemical recycling technologies enable the conversion of carbon-based waste materials into high-quality synthetic products, promoting circularity and avoiding carbon losses such as carbon emissions and waste accumulation in landfills and nature. Here, the construction and analysis of co-recycling scenarios show how the deployment of thermochemical recycling technologies can decouple the material system from fossil resource extraction. Furthermore, energy use is reduced if pyrolysis and/or gasification are included in the portfolio of recycling technologies. In a decarbonized energy system, deployment of co-recycling can lead to near-zero carbon emissions, while in more carbon-intensive energy systems the choice of thermochemical recycling route is key to limiting carbon emissions.

Geospatial supply-demand modeling of biomass residues for co-firing in European coal power plants
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Biomass co‐firing with coal is a near‐term option to displace fossil fuels and can facilitate development of biomass conversion and the build‐out of biomass supply infrastructure. A GIS‐based modeling framework (EU‐28, Norway, and Switzerland) is used to quantify and localize biomass demand for co‐firing in coal power plants and agricultural and forest residue supply potentials; supply and demand are then matched based on minimizing the total biomass transport costs (field‐to‐gate). Key datasets (e.g., land cover, land use, wood production) are available at 1,000 m or higher resolution, while some data (e.g., simulated yields) and assumptions (e.g., crop harvest index) have lower resolution and were re‐sampled to allow modeling at 1,000 m resolution. Biomass demand for co‐firing is estimated at 184 PJ in 2020, corresponding to an emissions reduction of 18 Mt CO2. In all countries except Italy and Spain, the sum of the forest and agricultural residues available at less than 300 km from a co‐firing plant exceeds the assessed biomass demand. The total cost of transporting residues to these plants is reduced if agricultural residues can be used, since transport distances are shorter. The total volume of forest residues less than 300 km from a co‐firing plant corresponds to about half of the assessed biomass demand. Almost 70% of the total biomass demand for co‐firing is found in Germany and Poland. The volumes of domestic forest residues in Germany (Poland) available within the cost range 2‐5 (1.5‐3.5) €/GJ biomass correspond to about 30% (70%) of the biomass demand. The volumes of domestic forest and agricultural residues in Germany (Poland) within the cost range 2‐4 (below 2) €/GJ biomass exceed the biomass demand for co‐firing. Half of the biomass demand is located within 50 km from ports, indicating that long‐distance biomass transport by sea is in many instances an option.

Geospatial supply-demand modeling of lignocellulosic biomass for electricity and biofuels in the European Union
- 2021
-
Ingår i: Biomass and Bioenergy. - : Elsevier BV. - 1873-2909 .- 0961-9534. ; 144

Tidskriftsartikel (refereegranskat)abstract
- Bioenergy can contribute to achieving European Union (EU) climate targets while mitigating impacts from current agricultural land use. A GIS-based modeling framework (1000 m resolution) is employed to match biomass supply (forest and agricultural residues, complemented by lignocellulosic energy crops where needed) with biomass demand for either electricity or bio-oil production on sites currently used for coal power in the EU-28, Norway, and Switzerland. The framework matches supply and demand based on minimizing the field-to-gate costs and is used to provide geographically explicit information on (i) plant-gate supply cost; (ii) CO2 savings; and (iii) potential mitigation opportunities for soil erosion, flooding, and eutrophication resulting from the introduction of energy crops on cropland. Converting all suitable coal power plants to biomass and assuming that biomass is sourced within a transport distance of 300 km, would produce an estimated 150 TW h biomass-derived electricity, using 1365 PJ biomass, including biomass from energy crops grown on 6 Mha. Using all existing coal power sites for bio-oil production in 100-MW pyrolysis units could produce 820 PJ of bio-oil, using 1260 PJ biomass, including biomass from energy crops grown on 1.8 Mha. Using biomass to generate electricity would correspond to an emissions reduction of 135 MtCO2, while using biomass to produce bio-oil to substitute for crude oil would correspond to a reduction of 59 MtCO2. In addition, energy crops can have a positive effect on soil organic carbon in most of the analyzed countries. The mitigation opportunities investigated range from marginal to high depending on location.

Applying a science-based systems perspective to dispel misconceptions about climate effects of forest bioenergy
- 2021
-
Ingår i: Global Change Biology Bioenergy. - : John Wiley and Sons Inc. - 1757-1693 .- 1757-1707. ; 13:8, s. 1210-1231

Tidskriftsartikel (refereegranskat)abstract
- The scientific literature contains contrasting findings about the climate effects of forest bioenergy, partly due to the wide diversity of bioenergy systems and associated contexts, but also due to differences in assessment methods. The climate effects of bioenergy must be accurately assessed to inform policy-making, but the complexity of bioenergy systems and associated land, industry and energy systems raises challenges for assessment. We examine misconceptions about climate effects of forest bioenergy and discuss important considerations in assessing these effects and devising measures to incentivize sustainable bioenergy as a component of climate policy. The temporal and spatial system boundary and the reference (counterfactual) scenarios are key methodology choices that strongly influence results. Focussing on carbon balances of individual forest stands and comparing emissions at the point of combustion neglect system-level interactions that influence the climate effects of forest bioenergy. We highlight the need for a systems approach, in assessing options and developing policy for forest bioenergy that: (1) considers the whole life cycle of bioenergy systems, including effects of the associated forest management and harvesting on landscape carbon balances; (2) identifies how forest bioenergy can best be deployed to support energy system transformation required to achieve climate goals; and (3) incentivizes those forest bioenergy systems that augment the mitigation value of the forest sector as a whole. Emphasis on short-term emissions reduction targets can lead to decisions that make medium- to long-term climate goals more difficult to achieve. The most important climate change mitigation measure is the transformation of energy, industry and transport systems so that fossil carbon remains underground. Narrow perspectives obscure the significant role that bioenergy can play by displacing fossil fuels now, and supporting energy system transition. Greater transparency and consistency is needed in greenhouse gas reporting and accounting related to bioenergy.

Tidskriftsartikel (refereegranskat)abstract
- Biomass co-firing with coal can help to reduce greenhouse gas emissions and can act as a low-cost stepping-stone for developing biomass supply infrastructures. This paper presents a techno-economic assessment of the biomass co-firing potential in coal-fired boilers in Czech Republic, France, Germany and Poland. The current coal power plant infrastructure is characterized by means of geographic location of the coal power plants, installed boiler capacity, type of boiler technology and year of commissioning, as extracted from the Chalmers Power Plant Database. The assessment considers type of boiler technology, type of biomass, co-firing fraction, implementation costs, breakeven prices for co-firing and an alkali index to determine the risk of high-temperature corrosion. The main factors affecting the co-firing potential are the biomass price, carbon price and alkali index. Results indicate that the total co-firing potential in the four countries is around 16 TWh year−1, with the largest potential from a conversion perspective in Germany, followed by Poland. Biomass co-firing with coal is estimated to be competitive at biomass prices below 13 € MWhinput−1 when the carbon price is 20 € t−1 CO2. On average, 1 TWh of electricity from biomass co-firing substitutes 0.9 Mt of fossil CO2 emissions. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

Co-firing biomass with coal for electricity generation—An assessment of the potential in EU27
- 2009
-
Ingår i: Energy Policy. - : Elsevier BV. - 0301-4215. ; 37:4, s. 1444-1455
-
Tidskriftsartikel (refereegranskat)abstract
- The European Union aims to increase bioenergy use. Co-firing biomass with coal represents an attractive near-term option for electricity generation from renewable energy sources (RES-E). This study assesses the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plant infrastructure in the EU27 Member States. The total technical potential for RES-E frombiomass co-firing amounts to approximately 50–90 TWh/yr, which requires a biomass supply of approximately 500–900 PJ/yr. The estimated co-firing potential in EU27 amounts to 20–35% of the estimated gap between current RES-E production and the RES-E target for 2010. However, for some member states the national co-firing potential is large enough to fill the national gap. The national biomass supply potential is considerably larger than the estimated biomass demand for co-firing for all member states. About 45% of the estimated biomass demand for co-firing comes from plants located close to the sea or near main navigable rivers and indicates the possibility for biomass import by sea transport. Thus, biomass co-firing has the potential to contribute substantially to the RES-E development in EU27.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The European Union aims at an enhanced use of bioenergy. Co-firing biomass with coal represents an attractive near-term option for electricity generation from renewable energy sources (RES-E). The purpose with this study is to assess the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plantinfrastructure in the EU27 Member States (MS). The technical potential for RES-E from biomass co-firing amounts toapproximately 50-90 TWh/year, which requires a biomass supply of approximately 500-900 PJ/year. The national biomass supply potential is considerably larger than the estimated biomass demand for each MS. However, actuallymeeting the possible co-firing biomass demand will require a substantial increase compared to the present primaryproduction of biomass in many MS. The implementation of biomass co-firing will be influenced by e.g., the availability and cost of different biomass resources as well as related transport and handling issues, the development of policies and competing options. Longer term, the biomass co-firing potential will be influenced by the development of carbon capture and storage. In the future work the RES-E generation from co-firing will be compared to the RES-E targets for 2010. The possibility for biomass import by sea will also be indicated.

- The European Union (EU) aims to increase the use of bioenergy. An increased production of electricity from renewable energy sources (RES-E) is also being promoted within the EU. Biomass co-firing with coal represents an attractive near-term option for increasing the production of RES-E. This study assesses the near-term technical potential for biomass co-firing with coal in the existing coal-fired power plant infrastructure in the EU27 Member States (MS) and relates the potential to the national EU targets for RES-E by 2010. The possible contribution of RES-E from biomass co-firing to the RES-E target for 2010 for EU27 as a whole (expressed in absolute numbers) is about 10%. However, the contribution from the estimated co-firing potential to the gap between current RES-E levels and the RES-E target for 2010 is about 20-33% for EU27 (depending on assumptions made). For some MS the potential contribution is large enough to fill the gap. Biomass co-firing with coal has the potential to play an important role when increasing the amount of RES-E in EU27. However, considering how little time remains, it is unlikely that co-firing can actually make a considerable contribution to the 2010 RES-E targets.

Metacognition and Learning Journals in Higher Education
- 2013

Ingår i: International Journal of Economics and Management Engineering. - 2226-7344. ; 3:4, s. 152-159
-
Tidskriftsartikel (refereegranskat)abstract
- The studies in higher education have its natural focus on the subject matters of study. This also holds for the master program Technology Management (TM). In addition it is important to complement the students’ academic knowledge with insights about metacognition, i.e. knowledge and understanding of themselves and their own behaviour. The introduction of so-called Learning Journals has proved to be a successful step in this direction. TM is a unique program at Lund University, where a selected number (40) of students from the Faculty of Economics (20) and from the Faculty of Engineering (20) are taught together during their last 2 years of study. Their different views on problems and challenges in today’s industry often complement each other. By the introduction of learning journals, they also learn about themselves, what influence their motivation, behaviour and attitude have on a group, and an understanding of their own preferred learning method. The learning journals are introduced in the course Project Leadership. In this course, the students are divided in groups of 4-5 students, each one managing one project. Throughout the whole course (2 semesters) the students are writing learning journals and supervisors are commenting monthly. The learning journals have four purposes; 1) providing an opportunity to reflect on the development of the project itself 2) enabling personal reflection on the own process, 2) enabling reflection on the own position and part in the group, and 4) through the longitudinal effect of the course; it provides an opportunity to compare journals over time to become aware of and able to analyse the own learning process. In a newly performed Placement report, students that have graduated from the Technology Management programme the last 10 years, rate their education 4.37 out of 5. Some students even consider the Learning Journals among the most valuable parts of the whole programme in retrospect.

Strindberg och skräcken : Skräckmotiv och identitetstematik i August Strindbergs författarskap
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The subject of this dissertation is the theme of identity in the works of August Strindberg and how this theme is explored through the use of motifs drawn from the literature of horror and fantasy as well as Swedish folklore. The theme deals with how the individual’s identity is shaped and what it consists of, and how it can be manipulated, stolen or lost through interaction with other people.The motifs studied are those of the homunculus, ghost, vampire and doppelgänger. These motifs are associated with their own specific set of functions, most of which in some way relate to the theme of identity. The motifs interact with each other and with the theme itself, creating an interplay which remains a constant throughout Strindberg’s works.Strindberg makes use of the motifs in both a metaphorical and literal sense, with for instance ghosts in some texts appearing as real to the characters who see them and in other texts being used metaphorically to represent the individual’s guilty conscience. This metaphorical use of the motifs shows how Strindberg appropriates the motifs from the genres in which they originally appear and reinvents them by giving them new functions in his own works. The texts studied show how Strindberg by using these motifs and transforming them makes them an integral part of his exploration of the theme of identity, which in turn is shown to be of central importance to an understanding of Strindberg’s works.

Staten och läromedlen : En studie av den svenska statliga förhandsgranskningen av läromedel 1938-1991
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Studien handlar om statlig påverkan på skolans läromedel. Här studeras såväl de politiska besluten om, som det konkreta genomförandet av, den svenska statliga förhandsgranskningen av läromedel, från starten 1938 till avskaffandet 1991. De politiska besluten och genomförandet sker på skilda arenor. Med hjälp av teoretiska begrepp från såväl läroplansteori som statsvetenskaplig implemen-teringsteori synliggörs och analyseras de olika arenorna samt relationerna mellan dem. Den politiska debatten studeras genom det offentliga trycket. Studien visar att granskningen infördes i politisk enighet och avskaffades helt utan politisk debatt. De politiska argumenten för granskning har varit att hålla priserna på läroböcker nere samt säkra läromedlens kvalitet. Vad som avsågs med kvalitet har dock varierat mellan olika aktörer och över tid. När det gäller genomförandet av granskningen studeras både Läroboks-/Läromedelsnämndens instruktioner till granskarna, och granskarnas utlåtanden om läromedel i samhällskunskap för gymnasieskolan. Den reella granskningen hade ofta fokus på att söka sakfel i läromedlen. Under 1970-talet fick objektivitetsfrågor genomslag i granskningen. Läroplanen, som betonades på den politiska arenan, användes dock i mindre utsträckning i det reella genomförandet av granskningen. Styrningsresultatet var beroende av aktörerna på realiseringsarenan och deras förståelse, vilja och kunnande. Styrningen kunde dock, i vissa fall, nå ända fram och påverka lärobokstexten. I dessa fall fanns en fungerande styrning från politisk debatt, via lagtext och granskning till en förändrad läromedelstext.

Effect of PEO-PPO-PEO Triblock Copolymers on Structure and Stability of Phosphatidylcholine Liposomes
- 1999

Tidskriftsartikel (refereegranskat)abstract
- The interactions of five poly(oxyethylene)-poly(oxypropylene)-poly(oxyethylene) (PEO-PPO-PEO), Pluronic, copolymers and phosphatidylcholine liposomes of varying composition have been studied. Structural studies were performed by means of cryo-transmission electron microscopy (c-TEM) and reveal that inclusion of low amounts (similar to 2 mol %) of Pluronics gives rise to significant morphological changes of the liposome preparations. Pluronics with large poly(oxyethylene) (PEO) blocks, such as F127, F108, and F87, induce the formation of bilayer disks, whereas those with comparably short PEO blocks, P105 and P85, tend to to promote a reduction in the liposome size. Inclusion of cholesterol in the liposomal preparations reduces the incorporation of copolymers in the lipid bilayer and thus reduces, and in some cases even abolishes, the morphological changes observed in the absence of cholesterol. The effect of the copolymers on liposome permeability was also investigated. All investigated copolymers were found to increase the leakage of carboxyfluorescein from preformed liposomes. This was true also in the case of cholesterol-containing Liposomes despite the fact that no change in the liposome structure could be observed by means of c-TEM. The magnitude of the induced leakage was found to correlate well with the hydrophobicity, as measured by the cmc, of the respective Pluronic. By raising the temperature or decreasing the solvency of the copolymer in the solution, the effect of the copolymer on liposome leakage was found to increase significantly.

Network composition
- 2005
-
Konferensbidrag (refereegranskat)abstract
- Network Composition is a concept that is being currently studied and under development in the Ambient Networks (AN) Project, a project that is sorted under the Wireless World Initiative (WWI), being part of EU's 6th framework program. Network Composition is a key concept in future interworking scenarios, which will be likely characterized by a prominent heterogeneity, in terms of subjacent technologies, available accesses, operators, etc. Hence, there is a need to provide means to allow these networks being dynamically interconnected through a uniform framework, so as to provide seamless and ubiquitous connectivity. The main aim of this paper is to highlight the need and potential benefits of this novel networking procedure, as well as setting its main aspects, in terms of required mechanisms.

Bokkapitel (refereegranskat)abstract
- The Swedish CArdioPulmonary bioImage Study (SCAPIS) combines the use of new imaging technologies, large-scale proteomics/metabolomics/genomics, and epidemiological analyses to extensively characterize a Swedish cohort of 30,000 men and women aged between 50 and 64 years. Its main aims are to improve risk prediction and to optimize our ability to study mechanisms of cardiopulmonary diseases. SCAPIS is currently recruiting at six sites in Sweden, and a pilot study was conducted in 2012 to test the feasibility of the comprehensive study protocol. In the planning phase, it was recognized that the detailed phenotyping used in SCAPIS would identify a large number of clinical findings in need of medical attention. This was confirmed by evaluation of results from the pilot study. Here we focus on pulmonary nodules and asymptomatic coronary artery stenosis. These clinical features were observed in a large number of participants, and the clinical handing and prognosis related to these observations are unclear. They thus posed great challenges for the study in their practical and ethical handling. This chapter describes how we developed procedures to handle these findings based on existing evidence and expert consensus as well as deliberations on ethical issues.

The retinoblastoma gene undergoes rearrangements in BRCA1-deficient basal-like breast cancer.
- 2012

Ingår i: Cancer Research. - 1538-7445. ; 72:16, s. 4028-4036

Tidskriftsartikel (refereegranskat)abstract
- Breast tumors from BRCA1 germ line mutation carriers typically exhibit features of the basal-like molecular subtype. However, the specific genes recurrently mutated as a consequence of BRCA1 dysfunction have not been fully elucidated. In this study, we utilized gene expression profiling to molecularly subtype 577 breast tumors, including 72 breast tumors from BRCA1/2 mutation carriers. Focusing on the RB1 locus, we analyzed 33 BRCA1-mutated, 36 BRCA2-mutated and 48 non-BRCA1/2-mutated breast tumors using a custom-designed high-density oligomicroarray covering the RB1 gene. We found a strong association between the basal-like subtype and BRCA1-mutated breast tumors and the luminal B subtype and BRCA2-mutated breast tumors. RB1 was identified as a major target for genomic disruption in tumors arising in BRCA1 mutation carriers and in sporadic tumors with BRCA1 promoter-methylation, but rarely in other breast cancers. Homozygous deletions, intragenic breaks, or microdeletions were found in 33% of BRCA1-mutant tumors, 36% of BRCA1 promoter-methylated basal-like tumors, 13% of non-BRCA1 deficient basal-like tumors, and 3% of BRCA2-mutated tumors. In conclusion, RB1 was frequently inactivated by gross gene disruption in BRCA1-related hereditary breast cancer and BRCA1-methylated sporadic basal-like breast cancer, but rarely in BRCA2-hereditary breast cancer and non-BRCA1-deficient sporadic breast cancers. Together, our findings demonstrate the existence of genetic heterogeneity within the basal-like breast cancer subtype that is based upon BRCA1-status.

Is there memory deficit in Parkinson’s disease? Explicit and implicit memory for verbal and action events
- 2001

Tidskriftsartikel (refereegranskat)abstract
- Three experiments examined both encoding and test variable whether there is any memory deficit in patients with Parkinson's disease in comparison with normal controls. In Experiment 1, the effect of encoding enactment was tested in free recall and cued recall. In Experiment 2, the combinations of enactment/non enactment and well/poorly integration variables were used at encoding. Again, the subjects were tested by free and cued recall. In Experiment 3, recognition memory and sentence-fragment completion tests were used with the same encoding manipulations as in Experiment 2. In general, the results of all three experiments showed no difference between PD patients and normal controls indicating that there is no memory deficit for PD patients. However, it was observed that there was some recognition deficit (especially for well integrated and verbal items) in Parkins on patients. It was suggested that the similarity between encoding and retrieval and the stage of disease should be considered as important factors for any possible memory deficit in Parkinsonian patients. It was also concluded that Parkinson patients are less well able to utilize cognitive support.

Reliable phase-contrast flow volume magnetic resonance measurements are feasible without adjustment of the velocity encoding parameter
- 2020
-
Ingår i: Journal of Medical Imaging. - 2329-4310 .- 2329-4302. ; 7:6

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To show that adjustment of velocity encoding (VENC) for phase-contrast (PC) flow volume measurements is not necessary in modern MR scanners with effective background velocity offset corrections. Approach: The independence on VENC was demonstrated theoretically, but also experimentally on dedicated phantoms and on patients with chronic aortic regurgitation (n = 17) and one healthy volunteer. All PC measurements were performed using a modern MR scanner, where the pre-emphasis circuit but also a subsequent post-processing filter were used for effective correction of background velocity offset errors. Results: The VENC level strongly affected the velocity noise level in the PC images and, hence, the estimated peak flow velocity. However, neither the regurgitant blood flow volume nor the mean flow velocity displayed any clinically relevant dependency on the VENC level. Also, the background velocity offset was shown to be close to zero (

Ingår i: GHGT 2018 - 14th International Conference on Greenhouse Gas Control Technologies. - : International Energy Agency Greenhouse Gas, IEAGHG.
-
Konferensbidrag (refereegranskat)abstract
- Negative CO2 emissions technologies include a number of technologies and biospheric storage options, the objective of which is the removal of atmospheric CO2 and thus the limitation of future global warming. An international conference on negative emissions technologies was conceived to meet the need for a broader understanding of the possibilities and challenges facing these technologies. The International Conference on Negative CO2 Emissions was held in May 22-24, 2018, at Chalmers University of Technology, Gothenburg, Sweden. The conference was organized by Chalmers with support from the Global Carbon Project, the City of Gothenburg, Nordic Energy Research, ECOERA, the Center for Carbon Removal, Göteborg Energi, Stockholm Exergi, and the International Energy Agency, i.e. IEAGHG, IEAIETS and IEA Bioenergy. The purpose of the conference was to bring together a wide range of scientific and technological disciplines and stakeholders, in order to engage in various aspects of research relating to negative CO2 emissions. This included various negative emission technologies, socio-economic and climate modelling, and climate policies and incentives. The conference was a major scientific event and the first in a conference series. The next conference will be held in the spring of 2020. This paper reports highlights and important messages from the conference.

Amplitude and phase control of attosecond light pulses
- 2005
-
Ingår i: Physical Review Letters. - 1079-7114. ; 94:3
-
Tidskriftsartikel (refereegranskat)abstract
- We report the generation, compression, and delivery on target of ultrashort extreme-ultraviolet light pulses using external amplitude and phase control. Broadband harmonic radiation is first generated by focusing an infrared laser with a carefully chosen intensity into a gas cell containing argon atoms. The emitted light then goes through a hard aperture and a thin aluminum filter that selects a 30-eV bandwidth around a 30-eV photon energy and synchronizes all of the components, thereby enabling the formation of a train of almost Fourier-transform-limited single-cycle 170 attosecond pulses. Our experiment demonstrates a practical method for synthesizing and controlling attosecond waveforms.

Artificial intelligence based automatic quantification of epicardial adipose tissue suitable for large scale population studies
- 2021
-
Ingår i: Scientific Reports. - : Springer Science and Business Media LLC. - 2045-2322 .- 2045-2322. ; 11:1

Tidskriftsartikel (refereegranskat)abstract
- To develop a fully automatic model capable of reliably quantifying epicardial adipose tissue (EAT) volumes and attenuation in large scale population studies to investigate their relation to markers of cardiometabolic risk. Non-contrast cardiac CT images from the SCAPIS study were used to train and test a convolutional neural network based model to quantify EAT by: segmenting the pericardium, suppressing noise-induced artifacts in the heart chambers, and, if image sets were incomplete, imputing missing EAT volumes. The model achieved a mean Dice coefficient of 0.90 when tested against expert manual segmentations on 25 image sets. Tested on 1400 image sets, the model successfully segmented 99.4% of the cases. Automatic imputation of missing EAT volumes had an error of less than 3.1% with up to 20% of the slices in image sets missing. The most important predictors of EAT volumes were weight and waist, while EAT attenuation was predicted mainly by EAT volume. A model with excellent performance, capable of fully automatic handling of the most common challenges in large scale EAT quantification has been developed. In studies of the importance of EAT in disease development, the strong co-variation with anthropometric measures needs to be carefully considered.

Tidskriftsartikel (refereegranskat)abstract
- The mechanism of atomic and molecular ionization in intense, ultra-short laser fields is a subject which continues to receive considerable attention. An inherent difficulty with techniques involving the tight focus of a laser beam is the continuous distribution of intensities contained within the focus, which can vary over several orders of magnitude. The present study adopts time of flight mass spectrometry coupled with a high intensity (8 X 10(15) Wcm(-2)), ultra-short (20 fs) pulse laser in order to investigate the ionization and dissociation of the aromatic molecule benzene-d1 (C6H5D) as a function of intensity within a focused laser beam, by scanning the laser focus in the direction of propagation, while detecting ions produced only in a "thin" slice (400 and 800 mum) of the focus. The resultant TOF mass spectra varies significantly, highlighting the dependence on the range of specific intensities accessed and their volumetric weightings on the ionization/dissociation pathways accessed.

Sexsäljares och sexköpares kollektiva handlande på internet : En svensk "fuckförening"?
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis aims to understand and explain the importance that prostitution forums have for the exercise of power and influence in the area of prostitution. It also seeks to clarify how these forums developed and were able to occur within a Swedish context. Sweden was the first country to legislate to criminalise only the buying, but not the sale, of sexual services. Social work provisions aims to get people out of prostitution. The thesis is based on an ethnographic study of the three largest Swedish prostitution forums during a two-year period. The empirical material consists of both quantitative participant and content analysis and field notes from observation of the interactions on the forums. The theoretical framework is based mainly on A Theory of Fields by Neil Fligstein and Doug McAdam. It focuses on the collective action on - and between - fields and how institutions are reproduced and changed. The results show that most of the content was published by a smaller group of actors. The interaction can be divided into the following subjects: social shims; information; negotiations and rules; advice and support; viewpoints on the forum as well as discussion on prostitution and its regulation. Moreover, the study shows that the forums enabled both sex service providers and sex clients to meet collectively, pursue common interests and discuss which rules should prevail in the prostitution market. Providers also pursued self-organised harm reduction social measures. This form of self-help was also sanctioned by a municipal prostitution unit, which can be interpreted as if it acted in a contrary direction to the government’s prostitution policy. The actors in the forums perceived themselves to be stigmatised by society, where sex service providers to a greater extent than sex clients, described a form of stigma. In the forums they could, however, feel a sense of belonging. The actors perceived themselves to be monitored by the Swedish state and they collectively self-regulated the interaction. Sex service providers and sex clients also co-operated, on occasions, with the Swedish state in order to jointly combat child prostitution, human trafficking and organised crime.

- Xylose is one of the few monosaccharidic building blocks that are used by mammalian cells. In comparison with other monosaccharides, xylose is rather unusual and, so far, only found in two different mammalian structures, i.e. in the Notch receptor and as the linker between protein and glycosaminoglycan (GAG) chains in proteoglycans. Interestingly, simple soluble xylopyranosides can not only initiate the biosynthesis of soluble GAG chains but also function as inhibitors of important enzymes in the biosynthesis of proteoglycans. Furthermore, xylose is a major constituent of hemicellulosic xylans and thus one of the most abundant carbohydrates on Earth. Altogether, this has spurred a strong interest in xylose chemistry. The scope of this review is to describe synthesis of xylopyranosyl donors, as well as protective group chemistry, modifications, and conformational analysis of xylose.

Estimating the environmental footprint of barley with improved nitrogen uptake efficiency—a Swedish scenario study
- 2016
-
Ingår i: European Journal of Agronomy. - : Elsevier BV. - 1161-0301 .- 1873-7331. ; 80, s. 45-54
-
Tidskriftsartikel (refereegranskat)abstract
- Plant breeding is a powerful tool for improving nitrogen (N) uptake efficiency and thus reducing the environmental impact relating to crop production. This study evaluated the environmental impact of current barley production systems in two Swedish agricultural areas (South and East) compared with scenarios with improved N uptake efficiency at two levels, in which the fraction of mineral N available for daily crop uptake was increased by 50 and 100%. Life cycle assessment (LCA) methodology was used to quantify energy use, global warming potential (GWP) and acidification and eutrophication potentials along the production chain for spring barley with differing N uptake efficiency, but similar N application rate. The functional unit, to which all energy use and emissions were related, was 1 Mg barley grain. Energy use, GWP and acidification proved to be higher for the East production system, mainly due to lower yield, while eutrophication was higher for South. The two impacts most affected by improved N uptake efficiency were eutrophication and GWP, with GWP decreasing due to a combination of higher yield, soil carbon sequestration and lower indirect emissions of N2O due to lower N leaching. Accounting for land savings due to increased yield, reducing the pressure to transform land elsewhere, would further lower the carbon footprint. Potential eutrophication per Mg grain was reduced by 15% in the production system with the highest N uptake efficiency in southern Sweden. Crops with improved N uptake efficiency can thus be an important complementary measure for reducing N losses to water, provided that the N application rate does not increase. However, incentives for farmers to maintain or even lower the N application rate might be required. Using simulation modelling is a promising approach for assessment of expected effects of improved crop varieties when no long-term experimental data are available. However, advanced crop models are required to better reflect the effect of plant breeding on e.g. expected yield. Future model development should involve expertise in plant breeding, plant physiology and dynamic crop and soil modelling.

Vital capacity and COPD: the Swedish CArdioPulmonary bioImage Study (SCAPIS)
- 2016
-
Ingår i: International Journal of Chronic Obstructive Pulmonary Disease. - : Informa UK Limited. - 1178-2005. ; 11:1, s. 927-933
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Spirometric diagnosis of chronic obstructive pulmonary disease (COPD) is based on the ratio of forced expiratory volume in 1 second (FEV1)/vital capacity (VC), either as a fixed value <0.7 or below the lower limit of normal (LLN). Forced vital capacity (FVC) is a proxy for VC. The first aim was to compare the use of FVC and VC, assessed as the highest value of FVC or slow vital capacity (SVC), when assessing the FEV1/VC ratio in a general population setting. The second aim was to evaluate the characteristics of subjects with COPD who obtained a higher SVC than FVC. Methods: Subjects (n=1,050) aged 50-64 years were investigated with FEV1, FVC, and SVC after bronchodilation. Global Initiative for Chronic Obstructive Lung Disease (GOLD) COPDFVC was defined as FEV1/FVC <0.7, GOLDCOPD(VC) as FEV1/VC <0.7 using the maximum value of FVC or SVC, LLNCOPDFVC as FEV1/FVC below the LLN, and LLNCOPDVC as FEV1/VC below the LLN using the maximum value of FVC or SVC. Results: Prevalence of GOLDCOPD(FVC) was 10.0% (95% confidence interval [CI] 8.2-12.0) and the prevalence of LLNCOPDFVC was 9.5% (95% CI 7.8-11.4). When estimates were based on VC, the prevalence became higher; 16.4% (95% CI 14.3-18.9) and 15.6% (95% CI 13.5-17.9) for GOLDCOPD(VC) and LLNCOPDVC, respectively. The group of additional subjects classified as having COPD based on VC, had lower FEV1, more wheeze and higher residual volume compared to subjects without any COPD. Conclusion: The prevalence of COPD was significantly higher when the ratio FEV1/VC was calculated using the highest value of SVC or FVC compared with using FVC only. Subjects classified as having COPD when using the VC concept were more obstructive and with indications of air trapping. Hence, the use of only FVC when assessing airflow limitation may result in a considerable under diagnosis of subjects with mild COPD.
