    Värdering av kulturella ekosystemtjänster baserat på bidrag till livskvalitet: slutrapport2017Report (Refereed)
    Abstract [sv]

    Rapporten presenterar resultaten av forskningsprojektet Värdering av kulturella ekosystemtjänster baserat på bidrag till livskvalitet, ett av sju projekt som ingår i forskningssatsningen Värdet av ekosystemtjänster. I projektet undersöks om etablerade teorier, begrepp och metoder från miljöpsykologisk forskning kring interaktionen mellan människa och naturmiljö kan bidra till förståelsen av kulturella ekosystemtjänster och deras värde.

    Projektet visar att värdet av grönområden kan beskrivas utifrån hur områ­ dena bidrar till närboendes livskvalitet genom att de ger möjlighet till miljö­ upplevelser, känsloresponser och aktiviteter som främjar hälsan, inte minst återhämtning. Slutsatsen är att kulturella ekosystemtjänster kan värderas ickemonetärt med utgångspunkt från väletablerade teorier, begrepp och metoder. Men forskarna ser att den kompetens som finns bland tjänstemän som arbetar med kulturella ekosystemtjänster idag behöver kompletteras med kunskap i beteendevetenskap.

    Ekosystemtjänster är grunden för vår välfärd. Ändå tar vi dem ofta för givna. Genom en ökad medvetenhet om och värdering av ekosystemtjänster kan vi påverka vår framtida välfärd och livskvalitet. Politiker, myndigheter, kommuner, företag och organisationer kan därigenom fatta mer välunderbyggda beslut.

Stefan Weisner har deltagit i projektet som expert på anlagda våtmarker. Samarbetspartners var Länsstyrelsen i Skåne, Hässleholms kommun, Staffanstorps kommun och Helsingborgs stad.

    Forskningssatsningen Värdet av ekosystemtjänster är en central insats för att nå ett av etappmålen inom miljömålssystemet genom att öka kunskapen om hur ekosystemtjänster bättre kan användas i olika beslutssituationer. Etappmålet innebär att betydelsen av biologisk mångfald och värdet av ekosystemtjänster senast 2018 ska vara allmänt kända och integreras i ekonomiska ställningstaganden, politiska avväganden och andra beslut i samhället där så är relevant och skäligt. Sju olika forskargrupper ingår i den omfattande satsningen som började 2014.

    Audio-visual reactions to wind turbines2003In: Acta Acoustica united with Acustica, ISSN 1610-1928, E-ISSN 1861-9959, Vol. 89, no Suppl.Article in journal (Refereed)
    Abstract [en]

    A cross sectional study with the aim of evaluating dose response relationships between noise exposure from wind turbines and subjective reactions was performed in a flat landscape in Sweden. The study area comprised 16 turbines. Subjective reactions were obtained by a questionnaire, which purpose was masked. The response rate was 69% (356 respondents). Outdoor noise levels (dBA) were calculated for each dwelling at 2.5 dB intervals. The results showed a significant dose response relationship between noise level and annoyance. The prevalence of noise annoyance was comparatively high. In the categories of greatest noise exposure 37.5-40 dBA and >40 dBA, 20% (95%Cl: ±12.4) and 36% (95%Cl: ±18.4) were very annoyed. The noise only explained part of the annoyance. Noise annoyance was also correlated to visual factors such as the respondents’ opinion of the turbines’ impact on the landscape. To further study interactions between noise annoyance and visual disturbance, the shadows from wind turbines (hours/year) were calculated for each respondent and used as dose for annoyance of shadows, but also as a variable when trying to explain noise annoyance. The results of the analysis and the possible interactions between audio and visual annoyance will be presented at the conference.

    Wetland areas' direct contributions to residents' well-being entitle them to high cultural ecosystem values2019In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 646, p. 1315-1326Article in journal (Refereed)
    Abstract [en]

    Wetlands in urban areas will be crucial to counteract the effects of climate change, for example, by improving flood protection and regulating local climate. To gain acceptance for larger-scale creation of wetlands, total values must be identified and revealed. Provisioning and regulating ecosystem services can be described as the quantitative effect, but cultural ecosystem services require other assessments. This study sought to determine whether peri-urban and urban wetland areas contribute to the well-being and quality of life of nearby residents, and to capture their value relative to two other types of green areas (i.e., parks and urban forests). A postal questionnaire survey, based on validated environmental psychology instruments, was distributed to residents in three municipalities with wetland areas of different structures and locations. In these municipalities, respondents (n = 474; response rate = 40%) reported that the wetland area contributed to several quality-of-life aspects, such as encountering nature and experiencing beauty. The areas also facilitated activities that support well-being, were perceived to have high restorative qualities, and evoked positive affective responses. All wetland areas were rated high on most of the measured concepts, but their value relative to other green areas differed possibly depending on the accessibility of the wetland and the availability of other green areas. The location and extent to which the wetland area was integrated in the residential area determined what quality-of-life aspects were most satisfied. Wetland areas can be ascribed cultural ecosystem service values based on how residents perceive their contribution to their quality of life. These values can be added to those of provisioning and regulating ecosystem services, forming the basis for planning urban environments. © 2018 The Authors

    Accessible urban waste heat: Deliverable 1.42018Report (Other academic)
    Abstract [en]

    This report presents the work performed in Task T1.2 of the ReUseHeat project to assess the accessible EU28 urban excess heat recovery potential from four unconventional excess heat sources: data centres, metro stations, service sector buildings, and waste water treatment plants. The report presents in overview and detail the concepts, data, basic premises, and methods, used to produce the results from this work. In all, excess heat potentials are modelled and spatially mapped for a total of some 26,400 unique activities, but by application of two new concepts: available excess heat and accessible excess heat, by which total potentials are distinguished from practical utilisation potentials, a significantly reduced count of some 6800 unique facilities represent the final cut. Common for these facilities are that they all are located inside or within 2 kilometres of urban district heating areas. For the total count of activities, the full available excess heat potential is assessed at some 1.56 EJ per year. At the restrained conditions, thus representing a conservative estimate, the final available excess heat potential from the four unconventional sources is estimated at 0.82 EJ per year, which here corresponds to a final accessible excess heat potential anticipated at 1.24 EJ annually.

    Methodologies and assumptions used in the mapping: Deliverable 2.3: A final report outlining the methodology and assumptions used in the mapping2017Report (Other academic)
    Abstract [en]

    This report is the main account for the methodologies, assumptions, data, and tools used in the WP2 mapping of the fourth Heat Roadmap Europe (HRE) project during its first reporting period (March 2016 to August 2017). During this period, the work with the major tasks assigned to WP2 in the project, including e.g. highly resolved spatial demand and resource atlases for the 14 MS´s of the EU under study, has resulted in a wide array of intermediate, complementary, and final outputs. Mentionable among these are for example hectare level projections of demand densities (residential and service sector heating and cooling demands) and investment costs for district heating and cooling systems, as well as feature polygon representations of current district heating cities in these countries. However, since the core focus here is to describe the methodological approaches and data sets used in the work, and not explicitly to present the results of the application of these, only a limited representative selection of study results are included in this report. For more exhaustive output presentations of the WP2 productions (apart from deliverables D2.1 and D2.2), all final output datasets generated are made available as operational layers in the online web map application Peta4 (the fourth Pan-European Thermal Atlas).

    Heat Roadmap Europe: Heat distribution costs2019In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 176, p. 604-622Article in journal (Refereed)
    Abstract [en]

    This analysis elaborates further the concept of physical and economic suitability for district heating in EU28 by an aggregation regarding key dimensions such as land areas, populations, heat demands, and investment volumes. This aggregation is based on a resolution on hectare level by slicing the total land area into 437 million pieces. Results show that heat demands in buildings are present in 9% of the land area. Because of high concentrations in towns and cities, 78% of the total heat demand in buildings originate from dense urban areas that constitute 1.4% of the total land area and 70% of the population. Due to these high heat densities above 50 MJ/m2 per year, the paper evaluates a setting where district heating is individually expanded in each member state for reaching a common 50% heat market proportion in EU28 at lowest cost. At this saturation rate, the aggregated EU28 district heat deliveries would increase to 5.4 EJ/a at current heat demands and represents an expansion investment volume, starting from current level of 1.3 EJ, of approximately 270 billion euro for heat distribution pipes. Given the current high heat densities in European urban areas, this study principally confirms earlier expectations by quantitative estimations. © 2019 Elsevier Ltd

    Optimizing Products and Production Using Additive Manufacturing by Introducing Bionics into the Engineering Design Process2017In: ASME 2017 International Mechanical Engineering Congress and Exposition, New York: ASME Press, 2017, article id V011T15A017Conference paper (Refereed)
    Abstract [en]

    In order to perform engineering design activities aiming at the design of new or redesign of existing products, a number of alternative processes, methods and techniques are available in the literature to the engineering designer/product developing enterprise. These processes, methods and techniques, are usually not explicitly expressed in terms of directives as to when and how they are to be used in the actual design of the product-to-be.

    An important goal in product development of today is to fulfill the terms for sustainable development, thus emphasizing the need to develop products which are not overexploiting the available resources provided by nature. By utilizing an approach to development and design based on bionics, i.e. utilizing biological methods and systems found in nature as a means of creating technical solutions, a conceptual framework is provided which is especially fit to accommodate the striving for sustainability.

    Striving for lightweight designs provides a significant potential to reduce the energy consumption of the product-to-be, which at present is a highly prioritized goal within sustainable development. Up until now, the dominating approach to lightweight designs has been to utilize lightweight materials such as different types of composites and metallic materials such as aluminum, magnesium and titanium.

    By introducing biomimicry into the engineering design process, an additional step towards efficient lightweight design solutions might be within reach. Since the objects created by nature are independent of costs and time, these are most often very complex especially regarding shapes and dimensions. In order to match these constraints in the creation of technical solutions (products), it is necessary to utilize optimization in combination with a flexible manufacturing process. The ideal manufacturing method to meet these demands is Additive Manufacturing (AM), though, at least for the time being, it imposes some constraints in size, costs etc. of the product to be manufactured.

    If the product designed is to be suitable for manufacturing for AM, it must be optimized, and so must the way it is to be processed. Therefore three of the most essential problems which need to be addressed in order to efficiently utilize AM are also elaborated upon and reported in the paper.

    The first of these problems is how to optimize the product-to-be. The second is to establish the orientation in which the product is to be manufactured during the AM process. The third is to find the best usage of the support material in the 3D printer, as there is no optimized process available for this activity. This is mainly due to the difficulties to foresee the waste of building material as, in most cases, this material can only be used once.

    In this paper, a process for the design and development of new products is proposed. The application of the process also includes essential elements to assure an efficient use of AM as mentioned above. The process is established on the basis of an integration of the Biomimicry Design Spiral, Bionic Structures and Elements and optimization into the Engineering Design Process. The utilization of the process is demonstrated by an application and reported in the form of a modified engineering design process — the Engineering Design and Biomimicry Design Process or the EDBP process for short.

    Experimental Verification of an Instrument to Test Flooring Materials2018In: IOP Conference Series: Materials Science and Engineering, Bristol: Institute of Physics Publishing (IOPP), 2018, Vol. 310, no 1, article id 012121Conference paper (Refereed)
    Abstract [en]

    The focus of this work is to validate the fluid model with different flooring materials and the measurements of an instrument to test flooring materials and its force attenuating capabilities using mathematical models to describe the signature and coefficients of the floor. The main contribution of the present work focus on the development of a mathematical fluid model for floors. The aim of the thesis was to analyze, compare different floor materials and to study the linear dynamics of falling impacts on floors. The impact of the hammer during a fall is captured by an accelerometer and response is collected using a picoscope. The collected data was analyzed using matlab least square method which is coded as per the fluid model. The finding from this thesis showed that the fluid model works with more elastic model but it doesn't work for rigid materials like wood. The importance of parameters like velocity, mass, energy loss and other coefficients of floor which influences the model during the impact of falling on floors were identified and a standardized testing method was set. © Published under licence by IOP Publishing Ltd.

    Predicting the effects of future climate change on the distribution of an endemic damselfly (Odonata, Coenagrionidae) in subtropical South American grasslands2018In: Journal of Insect Conservation, ISSN 1366-638X, E-ISSN 1572-9753, Vol. 22, no 2, p. 303-319Article in journal (Refereed)
    Abstract [en]

    Climate change is predicted to affect the distribution of freshwater taxa, and stronger impacts are expected on endemic species. However, the effects of future climates on freshwater insects from the Neotropical region have been generally overlooked. In this study, the distribution of a damselfly (Cyanallagma bonariense, Odonata, Coenagrionidae) endemic to the subtropical South American grasslands (Pampa) was modelled in relation to future scenarios of high greenhouse gas emissions (RCP 8.5) for 2050 and 2070. For this purpose, ecological niche models were developed based on assumptions of limited dispersal and niche conservatism, and the projected distribution of C. bonariense was contrasted with the location of current protected areas (PAs) in the Pampa. A broad potential distribution of C. bonariense was indicated throughout the Pampa, and projections predicted a predominance of range contractions rather than range shifts in climatically suitable areas for C. bonariense in 2050 and 2070. Projections of suitable areas overlapped in central Argentina and southernmost Uruguay in these periods. Our results indicated a potential resilience of C. bonariense to future climate change, which is likely related to the low restrictions in habitat use of C. bonariense. In every projection, however, most PAs were expected to lose effectiveness, as by 2070 most PAs fall outside the range of the predicted distribution of C. bonariense. Thus, the creation or enlargement of PAs in these areas is recommended and these results represent an important information for the conservation of endemic freshwater insects under global warming scenarios in an overlooked Neotropical landscape. © Springer International Publishing AG, part of Springer Nature 2018

    Predicting physiological parameters in fatiguing bicycling exercises using muscle activation timing2017In: Biomedical Signal Processing and Control, ISSN 1746-8094, E-ISSN 1746-8108, Vol. 35, p. 19-29Article in journal (Refereed)
    Abstract [en]

    This article is concerned with a novel technique for prediction of blood lactate concentration level and oxygen uptake rate from multi-channel surface electromyography (sEMG) signals. The approach is built on predictive models exploiting a set of novel time-domain variables computed from sEMG signals. Signals from three muscles of each leg, namely, vastus lateralis, rectus femoris, and semitendinosus were used in this study. The feature set includes parameters reflecting asymmetry between legs, phase shifts between activation of different muscles, active time percentages, and sEMG amplitude. Prediction ability of both linear and non-linear (random forests-based) models was explored. The random forests models showed very good prediction accuracy and attained the coefficient of determination R2 = 0.962 for lactate concentration level and R2 = 0.980 for oxygen uptake rate. The linear models showed lower prediction accuracy. Comparable results were obtained also when sEMG amplitude data were removed from the training sets. A feature elimination algorithm allowed to build accurate random forests (R2 > 0.9) using just six (lactate concentration level) or four (oxygen uptake rate) time-domain variables. Models created to predict blood lactate concentration rate relied on variables reflecting interaction between front and back leg muscles, while parameters computed from front muscles and interactions between two legs were the most important variables for models created to predict oxygen uptake rate.© 2017 Elsevier Ltd.

    Detection of paint polishing defects2018In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 6, no 2, article id 024009Article in journal (Refereed)
    Abstract [en]

    Surface finish plays a major role on perceived product quality, and is the first thing a potential buyer sees. Today end-of-line repairs of the body of cars and trucks are inevitably to secure required surface quality. Defects that occur in the paint shop, like dust particles, are eliminated by manual sanding/polishing which lead to other types of defects when the last polishing step is not performed correctly or not fully completed. One of those defects is known as 'polishing roses' or holograms, which are incredibly hard to detect in artificial light but are clearly visible in sunlight.

    This paper will present the first tests with a measurement set-up newly developed to measure and analyse polishing roses. The results showed good correlations to human visual evaluations where repaired panels were estimated based on the defects' intensity, severity and viewing angle.

    Study on surface texture of Fused Deposition Modeling2018In: Proceedings of the 8th Swedish Production Symposium (SPS 2018) / [ed] Mauro Onori, Lihui Wang, Xi Vincent Wang, Wei Ji, Amsterdam: Elsevier, 2018, Vol. 25, p. 8p. 389-396Conference paper (Refereed)
    Abstract [en]

    Fused Deposition Modeling (FDM) is mostly used to develop functional prototypes and in some applications for end-use parts. It is important to study the surfaces produced by FDM to understand the certainty of process. Truncheon design test artefacts are printed at different print settings and surfaces are measured using stylus profilometer. Taguchi’s design of experiments, signal-to-noise ratio and multiple regression statistics are implemented to establish a concise study of the individual and combined effect of process variables on surface texture parameters. Further, a model is developed to predict the roughness parameters and is compared with experimental values. The results suggest significant roughness parameter values decrease with increase in build inclination and increases with increase in layer thickness except the roughness peak count. © 2018 The Authors.

    Lead free Brass: Topography Characterization2016Conference paper (Refereed)
    Abstract [en]

    The negative effects of lead on human health and the recycling problems of copper alloys with lead content has led to the increase in concern for reducing/eliminating the use of lead in brass and other copper alloys. Many materials are considered to replace lead in brass; silicon is one such alternative. The real challenge prevails in sustainable manufacturing of lead free brass, to maintain control of the surface integrity when substituting the lead content in the brass with silicon. The investigation includes defined areal surface parameters measured on the turned samples of lead- and lead free brass using an optical coherence scanning interferometer, CSI.This paper deals with the study of surface topography of turned samples of lead and lead free brass. It is important to study the topographical characteristics of the brass samples which are the intermediate link between the manufacturing process variables and the functional behaviour of the surface. To numerically evaluate the sample’s surface topography and to validate the measurements for a significant study, a general statistical methodology is implemented. The results suggest that the surface roughness is higher in lead brass compared to lead free brass and tool coatings have significant influence on the hybrid (Sdr & Sdq) parameters in the surface topography of brass samples.

    Surface topography characterization of brass alloys: lead brass (CuZn39Pb3) and lead free brass (CuZn21Si3P)2017In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 5, no 2, article id 025001Article in journal (Refereed)
    Abstract [en]

    Manufactured surfaces usually consist of topographical features which include both those put forth by the manufacturing process, and micro-features caused by disturbances during this process. Surface characterization basically involves study of these features which influence the functionality of the surface. This article focuses on characterization of the surface topography of machined lead brass and lead free brass. The adverse effect of lead on human health and the environment has led the manufacturing sector to focus on sustainable manufacturing of lead free brass, as well as how to maintain control of the surface integrity when substituting the lead content in the brass with silicon. The investigation includes defined areal surface parameters measured on the turned samples of lead- and lead free brass using an optical coherence scanning interferometer, CSI. This paper deals with the study of surface topography of turned samples of lead-and lead free brass. It is important to study the topographical characteristics of the brass samples which are the intermediate link between the manufacturing process variables and the functional behaviour of the surface. To numerically evaluate the sample's surface topography and to validate the measurements for a significant study, a general statistical methodology is implemented. The results indicate higher surface roughness in turned samples of lead brass compared to lead free brass. © 2017 IOP Publishing Ltd

    Ecoregions within the Brazilian Pampa biome reflected in Odonata species assemblies2019In: Austral ecology (Print), ISSN 1442-9985, E-ISSN 1442-9993, Vol. 44, no 3, p. 461-472Article in journal (Refereed)
    Abstract [en]

    Based on vegetation composition, previous studies of the Pampa biome in southern Brazil have defined seven ecoregions within the area. Here, we test this ecoregion approach studying the semi-aquatic insect group Odonata in five of these regions, aiming at comparing the ecoregions to the more traditional environmental predictors of water quality and land cover. Based on a data set of occupancy comprising 99 species distributed between 131 localities, a one-way Permutational Multivariate Analysis of Variance was used to compare differences in the species composition between the ecoregions, followed by a Principal Component Analysis to visualize the variation. The composition varied significantly between all groups tested, and the ordination explained 61.8% of the variance. A partial redundancy analysis of ecoregions, land cover and water quality variables explained 71% of the variance in Odonata community structure. Ecoregion was the most important predictor, followed by water quality and land cover. Within these species assemblies, we could select certain species that were representative of a given ecoregion, to which their distribution within the Pampa biome was entirely or mainly confined. Of 24 representative species 41.7% were rare, while the rest were more abundant and, hence, easier to detect. We suspect that the differences found between the Pampa ecoregions might be due to geology, as such factors may be strong determinants of biodiversity. Specific ecological requirements at the family and genus levels also seemed to act selectively on the species compositions within the ecoregions. Today, the Pampa is highly fragmented due to agricultural activities such as rice cultivation, extensive cattle farming and forest plantations. We suggest that an ecoregion-based approach to the implementation of conservation measures may be the best way to help these distinct species assemblies survive. © 2018 Ecological Society of Australia

    Preliminary dragonfly (Odonata) species list from the Pampa biome in Rio Grande do Sul, Brazil, with ecological notes for 19 new records for the state2017In: Biota Neotropica, ISSN 1806-129X, E-ISSN 1676-0611, Vol. 17, no 4, article id e20170374Article in journal (Refereed)
    Abstract [en]

    An inventory of Odonata was carried out in the southern half of the state of Rio Grande do Sul, Brazil, in the Pampa biome. Originally, this biogeographical region was covered mostly by open fields and grassland, with sections of higher vegetation surrounding water bodies and rocky hills. Today the landscape is fragmented due to agricultural activities, mainly cattle farming, rice crops and forest plantations. Our survey was conducted in three municipalities from this region, between March 2015 and April 2016. Aiming at a general overview of the species composition, our sampling sites were selected on a wide basis, including lakes, bogs, temporary water bodies, small streams and river sections. Eighty two species of Odonata were collected comprising 40 genera and seven families. The dominant families were Libellulidae (56,1%), Coenagrionidae (24,5%) and Aeshnidae (7,3%). We found a diverse odonate assemblage, adding 19 new species records for the state of Rio Grande do Sul.

    Effects of exotic tree plantations on the richness of dragonflies (Odonata) in Atlantic Forest, Rio Grande do Sul, Brazil2016In: International Journal of Odonatology, ISSN 1388-7890, Vol. 19, no 4, p. 207-219Article in journal (Refereed)
    Abstract [en]

    One of the forest types occurring in Southern Brazil is the mixed ombrophilous forest (MOF), a subtype of the Atlantic Forest, which is one of the richest biomes on Earth. This biome currently remains as a highly fragmented mosaic, under pressure from human development. The diversity and ecology of most animal groups in this biome are poorly known. We studied Odonata in a large forest fragment, including an ecological reserve: the Floresta Nacional de São Francisco de Paula (FLONA-SFP), in Rio Grande do Sul, administrated by the Brazilian government. The reserve is dominated by MOF with sectors of Pinus elliottii and Araucaria angustifolia. Three surveys of these forest sectors over one year yielded 42 species, with the highest species richness recorded in the P. elliottii sector. The odonate species recorded here are all generalist in terms of habitat preferences, but they appeared only in low numbers and were very particular in their occurrence pattern. We therefore assume that the introduction of an alien element in the Atlantic Forest has given rise to a new species assemblage, where the ecology of the species is adapted to the novel habitat of Pinus plantations. As expected, the species occurring in the MOF sectors were mainly habitat specialists. The Araucaria plantations had an intermediate species composition. Despite the differences observed in habitat preference between generalist and specialist species, such exotic plantation habitats may act as a temporary biodiversity reservoir for further habitat colonization. © 2016 Worldwide Dragonfly Association

    List of Odonates from the Floresta Nacional de São Francisco de Paula (FLONA - SFP), with two new distribution records for Rio Grande do Sul, Brazil2016In: Biota Neotropica, ISSN 1806-129X, E-ISSN 1676-0611, Vol. 3, article id e20150132Article in journal (Refereed)
    Abstract [en]

    A survey of Odonata was carried out in the National Forest FLONA - SFP, Northeastern region of the Rio Grande do Sul state, Brazil. This conservation unit is mainly covered by Mixed Ombrophilous Forest (MOF), a subtype of Atlantic Forest biome, being also areas covered in planted Pinus, planted Araucaria and open fields. Our sampling efforts were conducted in thirty aquatic environments inside this reserve during the period between January 2014 and November 2014. The sampling sites were selected randomly, comprehending lakes, bogs, small streams and river sections, all inserted in the four vegetation types occurring in the reserve. Fortysix species of Odonata were collected and grouped into 23 genera and seven families. The dominant families were Coenagrionidae (32%), Libellulidae (32%), Aeshnidae (12%), and, Calopterygidae and Lestidae (9%). As expected, the findings revealed the presence of a highly diverse Odonate assemblage, mainly represented by generalist species in the most human disturbed sectors (Pinus and Open fields) and some specialist species in the pristine forest. Two species were registered for the first time in the state of Rio Grande do Sul, Brazil: Libellula herculea Karsch, 1889 (Libellulidae) and Heteragrion luizfelipei Machado, 2006 (Heteragrionidae). © 2016, Universidade Estadual de Campinas UNICAMP.

    Man-made lakes form species-rich dragonfly communities in the Brazilian Atlantic Forest (Odonata)2016In: Odonatologica, ISSN 0375-0183, Vol. 45, no 3-4, p. 135-154Article in journal (Refereed)
    Abstract [en]

    One of the forest types occurring in Southern Brazil is the Mixed Ombrophilous Forest (MOF), a subtype of the Atlantic Forest and one of the biodiversity hotspots on Earth. We sampled adult Odonata at 30 locations in the Floresta Nacional de São Francisco de Paula (FLONA-SFP), Rio Grande do Sul, Brazil, a national reserve which is divided into several sectors of MOF, planted Araucaria angustifolia, Pinus elliottii used for sustainable and financial purposes, and open fields. There are three types of aquatic environments in the reserve: lakes, swamps, and rivers/streams. Our aim was to obtain an overview of the species’ distribution patterns in the three types of aquatic environments and to evaluate the species occurring in lakes, an exclusively man-made habitat in this area. We recorded 46 species from seven odonate families; 25 species (x = 5.71 ± 1.77 SD) occurring in rivers/ streams, 24 in lakes (11.57 ± 2.15) and 21 in swamps (5.22 ± 3.60). Using Non-metric Multidimensional Scaling (NmDS), we showed that the species composition differed clearly between the three types of aquatic habitats. While swamps and rivers/streams had a relatively similar and uniform species composition, species in the lakes were more varied but the total species number was almost as high as that of the rivers/streams. The lake communities also differed distinctly from those of the other habitats, and we assume that the lake species originate from other degraded areas in the vicinity, indicating that the remains of the Atlantic Forest has already been strongly altered by humans. Given the poor knowledge of the Odonata in the Atlantic Forest/MOF, we hope that our study may increase the understanding of the communities, and contribute to the development of conservation measures for this fragmented biome.

    Water body type and land cover shape the dragonfly communities (Odonata) in the Pampa biome, Rio Grande do Sul, Brazil2018In: Journal of Insect Conservation, ISSN 1366-638X, E-ISSN 1572-9753, Vol. 22, no 1, p. 113-125Article in journal (Refereed)
    Abstract [en]

    The biogeographical region known as the Pampa biome in southern Brazil, was originally mainly covered with open fields or grassland, with areas of riparian forest surrounding the water bodies. Today this landscape appears highly fragmented due to agricultural activities such as rice cultivation, extensive cattle farming, and forest plantations. Studies have shown that the Pampa biome has high levels of biodiversity and endemism, but with regard to invertebrates, this biome is still one of the least known in Brazil. We therefore designed a study comparing the dragonfly (Odonata) communities to environmental and landscape features in this area, measuring diversity by species richness, relative abundance and Shannon index. Our results showed that the Pampa is a biome very rich in odonates, and that the species communities are highly dependent on the environmental conditions of the area. Habitats such as Rivers/Streams, bordered by native grasslands and riparian forests, were shown to harbour communities that were ecologically more complex and sensitive than other habitat types. Man-made lakes and agricultural areas displayed lower levels of biodiversity and odonate communities dominated by generalist species. By combining data on the communities of Odonata and other taxa, our analyses may be instrumental in determining priority areas for future conservation measures within the area. © 2018, Springer International Publishing AG, part of Springer Nature.

    Kansei, surfaces and perception engineering2016In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 4, no 3, article id 033001Article in journal (Refereed)
    Abstract [en]

    The aesthetic and pleasing properties of a product are important and add significantly to the meaning and relevance of a product. Customer sensation and perception are largely about psychological factors. There has been a strong industrial and academic need and interest for methods and tools to quantify and link product properties to the human response but a lack of studies of the impact of surfaces. In this study, affective surface engineering is used to illustrate and model the link between customer expectations and perception to controllable product surface properties. The results highlight the use of the soft metrology concept for linking physical and human factors contributing to the perception of products. Examples of surface applications of the Kansei methodology are presented from sauna bath, health care, architectural and hygiene tissue application areas to illustrate, discuss and confirm the strength of the methodology. In the conclusions of the study, future research in soft metrology is proposed to allow understanding and modelling of product perception and sensations in combination with a development of the Kansei surface engineering methodology and software tools.

    Old and new therapeutics for Rheumatoid Arthritis: in vivo models and drug development2016In: Immunopharmacology and immunotoxicology, ISSN 0892-3973, E-ISSN 1532-2513, Vol. 38, no 1, p. 2-13Article in journal (Refereed)
    Abstract [en]

    Development of novel drugs for treatment of chronic inflammatory diseases is to a large extent dependent on the availability of good experimental in vivo models in order to perform preclinical tests of new drugs and for the identification of novel drug targets. Here, we review a number of existing rodent models for Rheumatoid Arthritis in the context of how these models have been utilized for developing established therapy in Rheumatoid Arthritis and, furthermore, the present use of animal models for studies of novel drug candidates. We have studied the literature in the field for the use of in vivo models during development of anti-rheumatic drugs; from Methotrexate to various antibody treatments, to novel drugs that are, or have recently been, in clinical trials. For novel drugs, we have explored websites for clinical trials. Although a single Rheumatoid Arthritis in vivo model cannot mirror the complexity of disease development, there exist a number of good animal models for Rheumatoid Arthritis, each defining some parts in disease development, which are useful for studies of drug response. We find that many of the established drugs were not tested in in vivo models before being used in the clinic, but rather animal models have been subsequently used to find mechanisms for efficacy. Finally, we report a number of novel drugs, tested in preclinical in vivo models, presently in clinical trials. © 2016 Taylor and Francis.

    Analysis of polymorphisms in the mediator complex subunit 13-like (Med13L) gene in the context of immune function and development of experimental arthritis2018In: Archivum Immunologiae et Therapiae Experimentalis, ISSN 0004-069X, E-ISSN 1661-4917, Vol. 66, no 5, p. 365-377Article in journal (Refereed)
    Abstract [en]

    The Mediator complex subunit 13-like (MED13L) protein is part of the multi-protein mediator complex and plays an important role in gene transcription. Polymorphisms in the MED13L gene have been linked to congenital heart anomalies and intellectual disabilities. Despite recent evidence of indirect links of MED13L to cytokine release and inflammation, impact of genetic variations in MED13L on immune cells remains unexplored. The B10.RIII and RIIIS/J mouse strains vary in susceptibility to induced experimental autoimmune disease models. From sequencing data of the two mouse strains, we identified six polymorphisms in the coding regions of Med13l. By using congenic mice, we studied the effect of these polymorphisms on immune cell development and function along with susceptibility to collagen-induced arthritis, an animal model for Rheumatoid Arthritis (RA). Combining in vivo disease data, in vitro functional data, and computational analysis of the reported non-synonymous polymorphisms, we report that genetic polymorphisms in Med13l do not affect the immune phenotype in these mice and are predicted to be non-disease associated. © The Author(s) 2018

    The oncoprotein TBX3 is controlling severity in experimental arthritis2019In: Arthritis Research & Therapy, ISSN 1478-6354, E-ISSN 1478-6362, Vol. 21, no 1, article id 16Article in journal (Refereed)
    Abstract [en]

    Background: Development of autoimmune diseases is the result of a complex interplay between hereditary and environmental factors, with multiple genes contributing to the pathogenesis in human disease as well as in experimental models for disease. The T-box protein 3 is a transcriptional repressor essential during early embryonic development, in the formation of bone and additional organ systems, and in tumorigenesis.

    Methods: With the aim to find novel genes important for autoimmune inflammation, we have performed genetic studies of collagen-induced arthritis, a mouse experimental model for Rheumatoid Arthritis.

    Results: We show that a small genetic fragment on mouse chromosome 5, including Tbx3 and three additional protein-coding genes, is linked to severe arthritis and high titers of anti-collagen antibodies. Gene expression studies have revealed differential expression of Tbx3 in B-cells, where low expression was accompanied by a higher B-cell response upon B-cell receptor stimulation in vitro. Furthermore, we show that serum TBX3 levels rise concomitantly with increasing severity of CIA.

    Conclusions: From these results, we suggest that TBX3 is a novel factor important for the regulation of gene transcription in the immune system and that genetic polymorphisms, resulting in lower expression of Tbx3, are contributing to a more severe form of collagen-induced arthritis and high titers of autoantibodies. We also propose TBX3 as a putative diagnostic biomarker for rheumatoid arthritis.

    Effect of tree plantations on the functional composition of Odonata species in the highlands of southern Brazil2018In: Hydrobiologia, ISSN 0018-8158, E-ISSN 1573-5117, Vol. 808, no 1, p. 283-300Article in journal (Refereed)
    Abstract [en]

    Changes in biodiversity have mainly been assessed using taxonomical diversity indices. Although these approaches contribute to the scientific understanding of species richness and composition patterns, trait-based metrics may be more useful for detecting responses to land use change. We used odonates as a model system to compare traits composition in mixed ombrophilous forest (MOF) and tree plantations: exotic species (Pinus sp.) and native species (Araucaria angustifolia). Our goal was to understand and compare how each vegetation type affects the selection of species traits, and which factors are responsible for the presence of the species in the environment. We recorded 36 Odonata species distributed across 14 functional groups. The functional composition varied between MOF and exotic tree plantations and was similar between these two habitats and native tree plantations. Native forest favoured specialist traits. Our results suggest that the conversion of MOF to tree plantations, especially exotic ones, results in a shift to less specialized Odonata communities with altered functional group composition. This result highlights the negative impact associated with the conversion of native forests into exotic plantations. Our results show that odonates with specialist traits are limited to natural forest sites, which makes the conservation of such areas crucial. © 2017 Springer International Publishing AG, part of Springer Nature

    The training-specific adaptations resulting from resistance training, gymnastics and plyometric training, and non-training in adolescent athletes2017In: International journal of sports science & coaching, ISSN 1747-9541, E-ISSN 2048-397X, Vol. 12, no 6, p. 762-773Article in journal (Refereed)
    Abstract [en]

    Although previous research has investigated the training-specific adaptations to training in adults, there is a paucity of research aimed at investigating these adaptations in adolescent athletes. As such, adolescent athletes’ training-specific adaptations from three different training interventions were investigated in this study. Sixteen adolescent athletes participated in this study, whereby eight performed both training interventions and eight the non-training control. Pre- and post-testing was performed for each intervention with the testing battery: ultrasonography of the vastus lateralis and lateral gastrocnemius, countermovement jump, squat jump, and isometric mid-thigh pull. The resistance training group had large significant increases in isometric mid-thigh pull relative peak force (p < 0.01, g = 0.85 (−0.01, 1.71)) and vastus lateralis fascicle length (p = 0.04, g = 0.94 (0.07, 1.80)). The gymnastics and plyometric group demonstrated large significant changes in vastus lateralis pennation angle (p = 0.03, g = −0.94 (−1.81, −0.08)) and fascicle length (p = 0.03, g = 1.07 (0.19, 1.95)), and moderate significant increases in lateral gastrocnemius thickness (p = 0.01, g = 0.63 (−0.21, 1.47)) and eccentric leg stiffness (p = 0.03, g = 0.60 (−0.24, 1.44)). No significant changes were observed for any variables in the non-training group. The resistance training evoked increases in lower-body force producing capabilities, whereas the gymnastics and plyometric training evoked changes in muscle structure and inherent muscle qualities. © 2017, © The Author(s) 2017.

    Assessing and managing multiple risks in a changing world – The Roskilde recommendations2017In: Environmental Toxicology and Chemistry, ISSN 0730-7268, E-ISSN 1552-8618, Vol. 36, no 1, p. 7-16Article in journal (Refereed)
    Abstract [en]

    Roskilde University (Denmark) hosted a November 2015 workshop, Environmental Risk—Assessing and Managing Multiple Risks in a Changing World. This Focus article presents the consensus recommendations of 30 attendees from 9 countries regarding implementation of a common currency (ecosystem services) for holistic environmental risk assessment and management; improvements to risk assessment and management in a complex, human-modified, and changing world; appropriate development of protection goals in a 2-stage process; dealing with societal issues; risk-management information needs; conducting risk assessment of risk management; and development of adaptive and flexible regulatory systems. The authors encourage both cross-disciplinary and interdisciplinary approaches to address their 10 recommendations: 1) adopt ecosystem services as a common currency for risk assessment and management; 2) consider cumulative stressors (chemical and nonchemical) and determine which dominate to best manage and restore ecosystem services; 3) fully integrate risk managers and communities of interest into the risk-assessment process; 4) fully integrate risk assessors and communities of interest into the risk-management process; 5) consider socioeconomics and increased transparency in both risk assessment and risk management; 6) recognize the ethical rights of humans and ecosystems to an adequate level of protection; 7) determine relevant reference conditions and the proper ecological context for assessments in human-modified systems; 8) assess risks and benefits to humans and the ecosystem and consider unintended consequences of management actions; 9) avoid excessive conservatism or possible underprotection resulting from sole reliance on binary, numerical benchmarks; and 10) develop adaptive risk-management and regulatory goals based on ranges of uncertainty. © 2016 SETAC

    Synthesis of recent Swedish district heating research2018In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 151, p. 126-132Article in journal (Refereed)
    Abstract [en]

    In Sweden, district heating meets currently above half of the heat demands in buildings. District heating research in Sweden has a long tradition dating back to 1975. The latest research program period included 34 projects and was executed between 2013 and 2017. In this paper, a synthesis is performed on the Swedish research frontier by assessing these recent research projects. The three study purposes was to provide an overview over the executed projects, to identify new research questions, and to identify future challenges to the Swedish district heating industry. The assessment was based on six defined key areas, such as demand, resources, system frameworks, technology, cold supply, and international perspective. The subsequent content analysis was performed from three perspectives: the perspective of energy system transition, the customer perspective, and the sustainability perspective. Final conclusions include the three future challenges for the Swedish district heating industry. These are future strategies to communicate the value of district heating, vision for district heating beyond the transition to fossil free supply, and technology development for efficient use of low temperature heat sources. © 2018 Elsevier Ltd

    Dynamics of ammonia exchange with cut grassland: Synthesis of results and conclusions of the GRAMINAE Integrated Experiment2009In: Biogeosciences, ISSN 1726-4170, E-ISSN 1726-4189, Vol. 6, no 12, p. 2907-2934Article in journal (Refereed)
    Abstract [en]

    Improved data on biosphere-atmosphere exchange are fundamental to understanding the production and fate of ammonia (NH3) in the atmosphere. The GRAMINAE Integrated Experiment combined novel measurement and modelling approaches to provide the most comprehensive analysis of the interactions to date. Major intercomparisons of micrometeorological parameters and NH3 flux measurements using the aerodynamic gradient method and relaxed eddy accumulation (REA) were conducted. These showed close agreement, though the REA systems proved insufficiently precise to investigate vertical flux divergence. Grassland management had a large effect on fluxes: emissions increased after grass cutting (-50to 700 ngm-2 s-1 NH 3) and after N-fertilization (0 to 3800 ngm-2 s -1) compared with before the cut (-60 to 40 ngm-2 s -1). © Author(s) 2009.

    Symptoms of pain, fatigue and self-efficacy in young patients with spondyloarthritis: – a comparison between women and men2017In: Annals of the Rheumatic Diseases, ISSN 0003-4967, E-ISSN 1468-2060, Vol. 76, no Suppl. 2, p. 1515-1515Article in journal (Refereed)
    Abstract [en]

    Background; The disease spondyloarthritis (SpA) have often an early onset, and can debuts already in teenagers or young adults.  Knowledge of how these patients reporting pain, fatigue and self-efficacy can help to better understand the characteristics of women and men with SpA.

    Objectives: To study the differences between young women and men with SpA with regards to self-reported questionnaires on pain, fatigue and self-efficacy.

    A cross sectional population based cohort were used to create a young patients with SpA.

    Methods: The study is created on a cross-sectional population based cohort of patients with SpA.  They were identified through a health care register by searching for ICD-10 codes for SpA between the years 2003-2007, responding to a questionnaire survey in 2009. 201 patients, 18-36, 29% with the diagnosis of ankylosing spondylitis, 39% with psoriatic arthritis, and 32% with undifferentiated spondyloarhtritis form a subgroup of young patients eligible for analysis.  The surveys including questions concerning self-reported pain (NRS 0-10 and pain mannequin), fatigue (NRS 0-10), self-efficacy (ASES 10-100, low-high). The pain mannequin was used to categorize patients into groups; non chronic pain, chronic regional pain or chronic generalized pain. Self-reported disease activity (BASDAI 0-10) and health related quality of life (EQ5D, 0-1) were used to describe the group. Characteristic symptoms are reported as mean, standard deviation (SD) and frequencies. Mann- Whitney U test and Chi2 test were used to study gender differences.

    Results: The mean age (SD) was, 30 (5) years, 60 % were women. The group reported disease activity (BASDAI) of 3.8 (2.3), quality of life 0.75 (0.16), and that they had their diagnosis for 7 (5) years. One third were smokers or former smokers, and 69 % reached WHO’s recommended level of health enhancing physical activity. Women reported higher pain 3.9 (2.4) compared to men 2.9 (2.1), p=0.001. In the group of both women and men 21 % reported regional chronic pain, 41 % generalized chronic pain and the remaining 38 % reported non chronic pain. More women reported regional and generalized chronic pain than men, p=0.026. Women reported more fatigue 5.0 (2.6) compared to men 3.9 (2.7), p=0.003, less self-efficacy for pain 53 (20), compared to men 59 (21), p=0.041 and for symptoms 59 (19) compared to men 65 (20), p=0.045.

    Conclusion: A significant proportion of both women and men reported symptoms consistent with chronic generalized pain. Women reported generally impaired health compared to men, with a greater percentage with chronic pain, higher rates of pain and fatigue and reduced self-efficacy to manage pain and symptoms. This information could be valuable for clinicians in the care of young patients with SpA.

    Effects of harmful cyanobacteria on the freshwater pathogenic free-living amoeba Acanthamoeba castellanii2013In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 130, p. 9-17Article in journal (Refereed)
    Abstract [en]

    Grazing is a major regulating factor in cyanobacterial population dynamics and, subsequently, considerable effort has been spent on investigating the effects of cyanotoxins on major metazoan grazers. However, protozoan grazers such as free-living amoebae can also feed efficiently on cyanobacteria, while simultaneously posing a major threat for public health as parasites of humans and potential reservoirs of opportunistic pathogens. In this study, we conducted several experiments in which the freshwater amoeba Acanthamoeba castellanii was exposed to pure microcystin-LR (MC-LR) and six cyanobacterial strains, three MC-producing strains (MC-LR, MC-RR, MC-YR, MC-WR, [Dha7] MC-RR) and three strains containing other oligopeptides such as anabaenopeptins and cyanopeptolins. Although the exposure to high concentrations of pure MC-LR yielded no effects on amoeba, all MC-producing strains inflicted high mortality rates on amoeba populations, suggesting that toxic effects must be mediated through the ingestion of toxic cells. Interestingly, an anabaenopeptin-producing strain caused the greatest inhibition of amoeba growth, indicating that toxic bioactive compounds other than MCs are of great importance for amoebae grazers. Confocal scanning microscopy revealed different alterations in amoeba cytoskeleton integrity and as such, the observed declines in amoeba densities could have indeed been caused via a cascade of cellular events primarily triggered by oligopeptides with protein-phosphatase inhibition capabilities such as MCs or anabaenopeptins. Moreover, inducible-defense mechanisms such as the egestion of toxic, MC-producing cyanobacterial cells and the increase of resting stages (encystation) in amoebae co-cultivated with all cyanobacterial strains were observed in our experiments. Consequently, cyanobacterial strains showed different susceptibilities to amoeba grazing which were possibly influenced by the potentiality of their toxic secondary metabolites. Hence, this study shows the importance of cyanobacterial toxicity against amoeba grazing and, that cyanobacteria may contain a wide range of chemical compounds capable of negatively affect free-living, herbivorous amoebae. Moreover, this is of high importance for understanding the interactions and population dynamics of such organisms in aquatic ecosystems. (c) 2012 Elsevier B.V. All rights reserved.

    European Qualitative research project on Patient-preferred outcomes in Early Rheumatoid Arthritis (EQPERA): rationale, design and methods of a multinational, multicentre, multilingual, longitudinal qualitative study2019In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 9, no 3, p. 1-13, article id e023606Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Including the patient perspective is important to achieve optimal outcomes in the treatment of rheumatoid arthritis (RA). Ample qualitative studies exist on patient outcomes in RA. A Belgian study recently unravelled what matters most to patients throughout the overwhelming and rapidly evolving early stage of RA. The present study, European Qualitative research project on Patient-preferred outcomes in Early Rheumatoid Arthritis (EQPERA) was created to contribute to a more universal understanding of patient-preferred health and treatment outcomes by integrating the perspectives of patients with early RA from three European countries.

    METHODS AND ANALYSIS: In EQPERA, a qualitative, explorative, longitudinal study will be implemented in The Netherlands and Sweden, parallel to the methods applied in the previously conducted Belgian study. In each country, a purposive sample of patients with early RA will be individually interviewed 3-6 months after start of the initial RA treatment and subsequently, the same participants will be invited to take part in a focus group 12-18 months after RA treatment initiation. Data collection and analysis will be independently conducted by the local research teams in their native language. A meta-analysis of the local findings will be performed to explore and describe similarities, differences and patterns across countries.

    ETHICS AND DISSEMINATION: Ethics approval was granted by the responsible local ethics committees. EQPERA follows the recommendations of the Declaration of Helsinki. Two main papers are foreseen (apart from the data reporting on the local findings) for peer-reviewed publication.

    Potential approach towards effective topography characterization of 316L stainless steel components produced by selective laser melting process2018In: European Society for Precision Engineering and Nanotechnology, Conference Proceedings - 18th International Conference and Exhibition, EUSPEN 2018, Bedford: euspen , 2018, p. 259-260Conference paper (Refereed)
    Abstract [en]

    In this paper, an attempt is made to explain the surface texture of Selective Laser Melting (SLM) parts more satisfyingly than the existing methods. Investigations were carried out on the 316L stainless steel SLM samples. To account for most of the surface conditions, a truncheon artefact was employed for the analysis. A Stylus Profilometer was employed as a metrology tool for obtaining the 3D surface measurements. A methodology is proposed to extract and characterize the topographic features of Additive Manufactured (AM) surfaces. Here, the overall roughness of the surface is segregated into the roughness of the powder particles and the waviness due to thermal and the “staircase” effects. Analyzing these features individually results in an increased understanding of the AM process and an opportunity to optimize machine settings.

    Surface topography characterization using 3D stereoscopic reconstruction of SEM images2018In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 6, no 2, article id 024006Article in journal (Refereed)
    Abstract [en]

    A major drawback of the optical microscope is its limitation to resolve finer details. Many microscopes have been developed to overcome the limitations set by the diffraction of visible light. The scanning electron microscope (SEM) is one such alternative: it uses electrons for imaging, which have much smaller wavelength than photons. As a result high magnification with superior image resolution can be achieved. However, SEM generates 2D images which provide limited data for surface measurements and analysis. Often many research areas require the knowledge of 3D structures as they contribute to a comprehensive understanding of microstructure by allowing effective measurements and qualitative visualization of the samples under study. For this reason, stereo photogrammetry technique is employed to convert SEM images into 3D measurable data. This paper aims to utilize a stereoscopic reconstruction technique as a reliable method for characterization of surface topography. Reconstructed results from SEM images are compared with coherence scanning interferometer (CSI) results obtained by measuring a roughness reference standard sample. This paper presents a method to select the most robust/consistent surface texture parameters that are insensitive to the uncertainties involved in the reconstruction technique itself. Results from the two-stereoscopic reconstruction algorithms are also documented in this paper. © 2018 IOP Publishing Ltd.

    Exploring relations between EMG and biomechanical data recorded during a golf swing2017In: Expert systems with applications, ISSN 0957-4174, E-ISSN 1873-6793, Vol. 88, p. 109-117Article in journal (Refereed)
    Abstract [en]

    Exploring relations between patterns of peak rotational speed of thorax, pelvis and arm, and patterns of EMG signals recorded from eight muscle regions of forearms and shoulders during the golf swing is the main objective of this article. The linear canonical correlation analysis, allowing studying relations between sets of variables, was the main technique applied. To get deeper insights, linear and nonlinear random forests-based prediction models relating a single output variable, e.g. a thorax peak rotational speed, with a set of input variables, e.g. an average intensity of EMG signals were used. The experimental investigations using data from 16 golfers revealed statistically significant relations between sets of input and output variables. A strong direct linear relation was observed between lin- ear combinations of EMG averages and peak rotational speeds. The coefficient of determination values R2 = 0 . 958 and R2 = 0 . 943 obtained on unseen data by the random forest models designed to predict peak rotational speed of thorax and pelvis , indicate high modelling accuracy. However, predictions of peak rotational speed of arm were less accurate. This was expected, since peak rotational speed of arm played a minor role in the linear combination of peak speeds. The most important muscles to predict peak rotational speed of the body parts were identified. The investigations have shown that the canon- ical correlation analysis is a promising tool for studying relations between sets of biomechanical and EMG data. Better understanding of these relations will lead to guidelines concerning muscle engagement and coordination of thorax, pelvis and arms during a golf swing and will help golf coaches in providing substantiated advices. ©2017 Elsevier Ltd.

    National Large-Scale Wetland Creation in Agricultural Areas—Potential versus Realized Effects on Nutrient Transports2016In: Water, ISSN 2073-4441, E-ISSN 2073-4441, Vol. 8, no 11, article id 544Article in journal (Refereed)
    Abstract [en]

    During 2007–2013, the Swedish Board of Agriculture granted support within a national program to about 1000 wetlands, corresponding to a 5300-hectare wetland area, with the dual goal to remove nutrients from water and to improve biodiversity in agricultural landscapes. The aim of the present study was to compare the effects on nutrient transports that are realized within the national program to what could be obtained with the same area of wetlands if location and design of wetlands were optimized. In single, highly nutrient-loaded wetlands, a removal of around 1000 kg nitrogen and 100 kg phosphorus per hectare wetland area and year was estimated from monitoring data. Statistical models were developed to estimate the overall nutrient removal effects of wetlands created within the national program. Depending on model, the effect of the national program as a whole was estimated to between 27 and 38 kg nitrogen and between 2.7 and 4.5 kg phosphorus per hectare created wetland area and year. Comparison of what is achieved in individual wetlands to what was achieved in the national program indicates that nutrient removal effects could be increased substantially in future wetland programs by emphasising location and design of wetlands.

    District heating and cooling in Sweden2017In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 126, p. 419-429Article in journal (Refereed)
    Abstract [en]

    The purpose with this review is to provide a presentation of the background and current position for district heating and cooling in Sweden. The review structure considers the market, technical, supply, environmental, institutional, and future contexts. The main conclusions are high utilisation of district heating in Swedish buildings, commitment to the third generation of district heating technology, high proportions of heat recycling and renewable supply, high compliance to European definition of efficient district heating, considerable reductions of fossil carbon dioxide emissions, strong national driving forces from high fossil fuel taxes, and soft district heating regulation based on transparency. District cooling systems are small compared to district heating systems. From strong legislative driving forces, the Swedish heat market became a testing ground for a market situation when fossil fuels are expensive in a heat market. The long-term market solutions have then become district heating in dense urban areas and local heat pumps in suburban and rural areas. © 2017 The Author. Published by Elsevier Ltd.

    International review of district heating and cooling2017In: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 137, p. 617-631Article, review/survey (Refereed)
    Abstract [en]

    The purpose with this review is to provide a presentation of the background for the current position for district heating and cooling in the world, with some deeper insights into European conditions. The review structure considers the market, technical, supply, environmental, institutional, and future contexts. The main global conclusions are low utilisation of district heating in buildings, varying implementation rates with respect to countries, moderate commitment to the fundamental idea of district heating, low recognition of possible carbon dioxide emission reductions, and low awareness in general of the district heating and cooling benefits. The cold deliveries from district cooling systems are much smaller than heat deliveries from district heating systems. The European situation can be characterised by higher commitment to the fundamental idea of district heating, lower specific carbon dioxide emissions, and higher awareness of the district heating and cooling benefits. The conclusions obtained from the six contexts analysed show that district heating and cooling systems have strong potentials to be viable heat and cold supply options in a future world. However, more efforts are required for identification, assessment, and implementation of these potentials in order to harvest the global benefits with district heating and cooling. © 2017 The Author
