    Design and development of a climatic wind tunnel for physiological sports experimentation2019In: Proceedings of the Institution of Mechanical Engineers, Part P: Journal of Sports Engineering and Technology, ISSN 1754-3371, Vol. 233, no 1, p. 86-100Article in journal (Refereed)
    Abstract [en]

    The aim of this project was to develop a wind tunnel that enables the study of human performance during various types ofsports and physical activities by examining the influence of aerodynamic drag, precipitation, frictional forces and gravitationalforces on uphill and downhill travel on a moving substrate. An overall design for a wind tunnel and working section containinga large treadmill was drafted, followed by computational fluid dynamics simulations of flow conditions to assess thedesign’s feasibility and select from different geometries prior to its construction. The flow conditions in the completed windtunnel were validated using different flows, speeds and treadmill inclinations. Pilot experiments were carried out using across-country skier to investigate the effect of aerodynamic drag on oxygen uptake during double poling and the maximalachieved speed when rolling on a declined treadmill. The purpose was to validate the usefulness of the tunnel. The resultsshowed that flow conditions are acceptable for experiments even in worst-case scenarios with maximal inclined and declinedtreadmill. Results also showed that aerodynamic drag has a significant impact on the skier’s energy expenditure.

    The effect of speed and gradient on running economy and oxygen uptake during downhill running2019Conference paper (Refereed)
    Abstract [en]

    Downhill running poses challenges were the gradient is of importance for energy cost and oxygen uptake. While demonstrated that downhill running at a slight gradient is most efficient, the energy cost increases with a steeper gradient (1). However, the additional effect of running speed has not been studied for downhill running. Therefore, the aim of the study was to analyse the combined effect of gradient and speed in downhill running on oxygen cost and running economy. METHODS:Runners (n=6) were recruited for the study and performed 1) VO2max and running economy (J·kg-1·m-1) tests and 2) an experimental running protocol at two speeds,12 km·h-1 and 80% of the speed at VO2max (V80) and three gradients (0, -5° and -10°). V80 was higher than 12 km·h-1 for all participants. All testing was performed on a large treadmill 3x5 m (Rodby, Sweden) that were controlled for speed and gradient. The experimental protocol was performed continuously with 5 min at each workload in a randomized order, 30 min in total. VO2 was measured throughout the experimental protocol using a mixing chamber (Moxus Metabolic Cart, USA). RESULTS:VO2 expressed as ml·kg-1·min-1 increased because of speed (F1,5=27.8, p=0.003) and decreased with gradient (F1,5=87.6, p<0.001). Between -5° and -10°, VO2 decreased less during V80 compared to 12 km·h-1 shown by an interaction (F2,10=7.9, p=0.009). However, speed did not influence running economy (F1,5=0.9, p=0.38) while gradient increased running economy (F1,5=90.1, p<0.001). A non-significant interaction effect suggests a shift in running economy between -5° and -10° depending on speed (F2,10=3.5, p=0.07). The running economy at V80 was higher compared to 12 km·h-1 at -5° but reversed at -10°. While a relation between running economy at V80 -10°, V80 -5° and 12 km·h-1 -10° (rs>0.88, p<0.019) was found, no relations between running economy on level terrain and steep downhill running (-10°) were recognised. CONCLUSION:While we found no effect on running economy from speed alone, we did see a shift in the running economy for different speeds at an increased downhill gradient. This indicates that a high speed (V80) is more efficient at moderate downhill gradients, while a lower speed (12 km·h-1) is more efficient in steeper downhill gradients. While previous research demonstrate that gradient is of great influence to running economy, the findings of this study suggest that speed also affects the running economy in downhill running.

    Text Mining The Quality Paradigm(s)2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The purpose of this thesis orbits around an examination of the formation of a quality paradigm. In this inquiry, the exploration and application of text mining have been used to provide new insights into quality as a paradigm.

    The findings reveal the existence of unifying topics, around which research on quality has clustered, constituting the foundational pillars of an academic quality paradigm. These foundational pillars are operational paradigms that embody both epistemological perspectives and operational concerns regarding quality. The three operative paradigms upon which the quality paradigm rests are the operative paradigm of back-end quality (orbiting around: QM, TQM and service quality), the operative paradigm of middle-way quality (orbiting around: ISO, BEMs and Quality Awards) and the operative paradigm of front-end quality (orbiting around: Reliability, Costs and Processes). The three operative paradigms differ in their levels of abstraction, accountability and system-learning emphasis. However, the mutual purpose and aim of the three operative paradigms, and hence the paradigm as a whole, is to continuously control, assure and develop systems affecting quality initiatives in service of the customer(s).

    The findings also indicate that the operative paradigms of back-end and front-end quality seem to be specializing and drifting apart, which might lead to a division of the quality paradigm into two separate paradigms.

    The studies in this thesis also confirm the existence of changes in the focus and popularity of specific topics. However, the key epistemological findings are the central and perpetual research topics that are identified – supporting the supposition that research on quality truly constitutes a delimited and recognized research paradigm.

    Furthermore, the studies show that research on quality expanded during the end of the 1980s and beginning of the 1990s, after which a contraction took place, followed by stability at the start of the 21st century. Consequently, it is found that research on quality entered a stable and mature phase in the 21st century, settling down as a distinctive and established research paradigm.

    Finally, it is found that the exploration and application of text mining is a potent approach when probing the epistemological foundations of an academic discipline.

    Four decades of research on quality: summarising, Trendspotting and looking ahead2019In: Total quality management and business excellence (Online), ISSN 1478-3363, E-ISSN 1478-3371Article in journal (Refereed)
    Abstract [en]

    The purpose of this paper is to identify and depict the key areas around which research on quality has orbited during the past 37 years. Additionally, this paper aims to explore longitudinal patterns and trends in the identified key areas. Thereby, this study aims to present new perspectives on the foundational elements and evolutionary patterns of research on quality as well as future directions. The paper applies data- and text modelling methodology to a chronological dataset covering 37 years and consisting of scientific journals specialising in research on quality; it also includes scientific journals with a broader spectrum of operations management (OM) research. The study identifies seven central topics around which research on quality has centred during this time period: Service Quality & Customer Satisfaction; Process design & Control; ISO Certification & Standards; TQM - Implementation, Performance & Culture; QM - Practices & Performance; Reliability, Costs, Failure & Problems and Excellence - BEMs, Quality Awards & Excellence in Higher Education. The results also show that the total number of entries has risen constantly since 1980; however, there was a period of decline between 2000 and 2012, indicating that after almost four decades, research on quality is still vibrant and relevant.

    Processorienterad kultur: Mätmetod över beteenden som driver resultat i en processorienterad kultur2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The authors of this thesis got the idea to this projekt from a lecture and from Drucker´s quote “Culture eats strategy for breakfast”. The purpose was to investigate what behaviours that drives results in a process oriented culture, and to develop a model for measuring these behaviours.

     

    The goal was to measure the behaviours in the organisation and to help them obtain a culture that exceed the culture of their competitors, and reaching process orientation using a quantitative survey in a pilot study. Even though we got answers from all participants in the survey, the population was too small to generate statistically significant results. The study is based on the theory of four clusters; “fumblers”, “talkers”, “organisers”, and “mappers” by Eriksson and Hellström (2013) and the results are displayed in diagrams and an IPA-matrix.

     

    The conclusion is that the organisation leans towards function orientation, but they are striving towards becoming process orientated. The total picture the authors got is they belong to the cluster “talkers” with a slight margin. They are heading in the direction of becoming process orientated by focusing on their communication though. The model was designed using research about what behaviours have a positive or a negative effect on the processorientated culture of the organisation. The weakness of the model is that it only takes the cornerstone “working with processes” into account and does not measure the other perspectives of quality culture.

    Surface modification of Ti6Al4V alloy scaffolds manufactured by electron beam melting2019In: / [ed] Godymchuk A.,Rieznichenko L.,Semenov M., Institute of Physics Publishing (IOPP), 2019, no 1Conference paper (Refereed)
    Abstract [en]

    In this paper, the results of the surface functionalization of the Ti6Al4V alloy scaffolds with different structures for use as a material for medical implants are presented. Radio frequency magnetron sputtering was used to modify the surface of the porous structures by deposition of the biocompatible hydroxyapatite (HA) coating with the thickness of 86050 nm. The surface morphology, elemental and phase composition of the HA-coated scaffolds were studied. According to energy-dispersive X-ray spectroscopy, the stoichiometric ratio of Ca/P for flat, orthorhombic and cubic scaffolds is 1.65, 1.60, 1.53, respectively, which is close to that of stoichiometric ratio for HA (Ca/P = 1.67). It was revealed that this method of deposition makes it possible to obtain the homogeneous crystalline coating both on the dense sample and in the case of scaffolds of complex geometry with different lattice cell structure.

    Adhesion, proliferation, and osteogenic differentiation of human mesenchymal stem cells on additively manufactured Ti6Al4V alloy scaffolds modified with calcium phosphate nanoparticles2019In: Colloids and Surfaces B: Biointerfaces, ISSN 0927-7765, E-ISSN 1873-4367, Vol. 176, p. 130-139Article in journal (Refereed)
    Abstract [en]

    In the present study, biocomposites based on 3D porous additively manufactured Ti6Al4V (Ti64) scaffolds modified with biocompatible calcium phosphate nanoparticles (CaPNPs) were investigated. Ti64 scaffolds were manufactured via electron beam melting technology using an Arcam machine. Electrophoretic deposition was used to modify the scaffolds with CaPNPs, which were synthesized by precipitation in the presence of polyethyleneimine (PEI). Dynamic light scattering revealed that the CaP/PEI nanoparticles had an average size of 46 ± 18 nm and a zeta potential of +22 ± 9 mV. Scanning electron microscopy (SEM) revealed that the obtained spherical CaPNPs had an average diameter of approximately 90 nm. The titanium-based scaffolds coated with CaPNPs exhibited improved hydrophilic surface properties, with a water contact angle below 5°. Cultivation of human mesenchymal stem cells (hMSCs) on the CaPNPs-coated Ti64 scaffolds indicated that the improved hydrophilicity was beneficial for the attachment and growth of cells in vitro. The Ti6Al4V/CaPNPs scaffold supported an increase in the alkaline phosphatase (ALP) activity of cells. In addition to the favourable cell proliferation and differentiation, Ti6Al4V/CaPNPs scaffolds displayed increased mineralization compared to non-coated Ti6Al4V scaffolds. Thus, the developed composite 3D scaffolds of Ti6Al4V functionalized with CaPNPs are promising materials for different applications related to bone repair.

    Powder-bed additive manufacturing for aerospace application: Techniques, metallic and metal/ceramic composite materials and trends2019In: MANUFACTURING REVIEW, ISSN 2265-4224, Vol. 6, article id 5Article, review/survey (Refereed)
    Abstract [en]

    The current paper is devoted to classification of powder-bed additive manufacturing (PB-AM) techniques and description of specific features, advantages and limitation of different PB-AM techniques in aerospace applications. The common principle of "powder-bed" means that the used feedstock material is a powder, which forms "bed-like" platform of homogeneous layer that is fused according to cross-section of the manufactured object. After that, a new powder layer is distributed with the same thickness and the "printing" process continues. This approach is used in selective laser sintering/melting process, electron beam melting, and binder jetting printing. Additionally, relevant issues related to powder raw materials (metals, ceramics, multi-material composites, etc.) and their impact on the properties of as-manufactured components are discussed. Special attention is paid to discussion on additive manufacturing (AM) of aerospace critical parts made of Titanium alloys, Nickel-based superalloys, metal matrix composites (MMCs), ceramic matrix composites (CMCs) and high entropy alloys. Additional discussion is related to the quality control of the PB-AM materials, and to the prospects of new approaches in material development for PB-AM aiming at aerospace applications.

    X-ray computed tomography of multiple-layered scaffolds with controlled gradient cell lattice structures fabricated via additive manufacturing2019Conference paper (Refereed)
    Abstract [en]

    In this paper we report on the characterization by X-ray computed tomography of calcium phosphate (CaP) and polycaprolactone (PCL) coatings on Ti-6Al-4V alloy scaffolds used as a material for medical implants. The cylindrical scaffold has greater porosity of the inner part than the external part, thus, mimicking trabecular and cortical bone, respectively. The prismatic scaffolds have uniform porosity. Surface of the scaffolds was modified with calcium phosphate (CaP) and polycaprolactone (PCL) by dip-coating to improve biocompatibility and mechanical properties. Computed tomography performed with X-ray and synchrotron radiation revealed the defects of structure and morphology of CaP and PCL coatings showing small platelet-like and spider-web-like structures, respectively.

    Accelerating sustainable society and a flourishing Scandinavia through a living and communicating network of AI-summits2019Conference paper (Refereed)
    Abstract [en]

    The need for a radical transformation of society, business and way of life towards sustainability is by now widely accepted and acknowledged in the Mid Scandinavian region. This transformation also occurs as a major objective in the UN Sustainable Development Goals, both nationally and locally. However, after creating awareness, moving from knowing to doing is now the real challenge. Pushing for sustainability in strategies and visions, or even providing extensive funding for projects related to sustainable development is not doing the job fast enough. One obvious reason being that the more sustainable ideas and solutions of the future do require new levels of systems thinking and solutions on the level of the “whole system”. That in turn is dependent on connections and relations across traditional silos and organizational borders that currently does not exist. Therefore, stakeholders from Sweden and Norway are currently experimenting together on using a living and communicating network of Appreciative Inquiry Summits to accelerate sustainable, circular, and flourishing development in Scandinavia. The initiative is designed as an innovation project with hands-on exploring, prototyping, as well as researching how to accelerate the desired transformation. The project, called SMICE, is inspired by the “whole system in the room” approach of the amazing initiative “Sustainable Cleveland 2019”. However, as the context of this initiative is a large sparsely populated region, including also several countries, the set up now evolving is moving beyond just one annual big AI-summit towards more of a distributed system, “ecosystem”, or network of AI-summits and other resources that live, communicate and relate to each other continuously. During this presentation we will share our progress made, results, learnings, challenges, insights, and practices from our exciting and important journey so far.

    Laboratory Investigation of Different Insulating Materials Used for Snow Storage2019In: Journal of cold regions engineering, ISSN 0887-381X, E-ISSN 1943-5495, Vol. 33, no 4, article id 04019012Article in journal (Refereed)
    Abstract [en]

    Storage of snow has become of increasing interest for the winter business industry. Covering a pile of snow with an insulating material protects the snow from heat transfer from the surroundings and reduces the melting. Storing snow enables ski resorts to set an opening date, and it can also be used to secure winter sports events that are dependent on snow. Cover materials that are commonly used as insulation are wood-based materials, such as sawdust, and textile materials and sheets. How efficiently a cover material functions as thermal insulation depends on the material characteristics and thickness of the insulating layer. In this study, results from a laboratory experiment are presented, which aimed at comparing different commonly used cover materials, as well as some other materials that have not previously been used as thermal insulation on snow. Different layer thicknesses were also investigated. The results show that the insulating capacity of sawdust is reduced with time. Despite degrading insulating properties with time, sawdust is still considered one of the best materials to use as insulation on snow, and it is also more efficient than the textile materials investigated in this study. Doubling the textile layers or adding a three-dimensional (3D) spacer textile, which implies adding a layer of air between the textile and the snow, reduces the snow melting. Water absorption, water transport, and evaporation of water affect the melting. In this work, evaporative cooling did not prove to reduce melting; therefore, it was not evident whether a textile material should be permeable. An interesting material used in the study was Quartzene, which absorbed all the melt water and protected the snow most efficiently of the materials tested.

    Interlinking Lean and Sustainability: How ready are leaders?2019In: The TQM Journal, ISSN 1754-2731, E-ISSN 1754-274X, Vol. 31, no 2, p. 136-149Article in journal (Refereed)
    Abstract [en]

    Purpose: The purpose of this paper is to explore evidence of interlinkages between Lean and sustainability among organisational leaders in the early stages of Lean implementation.

    Design/methodology: A multiple-site case study was conducted to study the connections between Lean and sustainable development during the implementation stages of a Lean practice. In-depth interviews were conducted with managers about their knowledge and understanding of the interlinkages between Lean and sustainable development. The findings were then used as an analytic frame to determine whether these interlinkages were present in the organisation.

    Findings: Evidence of interlinkages between Lean and sustainable development was found; however, their presence was incomplete and inconsistent across clinics.

    Research implications: Insights from the research can help organisations plan for the implementation of Lean practice, particularly when a sub-goal is to achieve sustainable development.

    Originality/value: The study shows the importance of focusing on managers’ knowledge and understanding of the interlinkages between Lean and sustainable development when implementing Lean in order to utilise Leans full potential to achieve sustainability.

    Marine Polysaccharide-Collagen Coatings on Ti6Al4V Alloy Formed by Self-Assembly2019In: Micromachines, ISSN 2072-666X, E-ISSN 2072-666X, Vol. 10, no 1, article id 68Article in journal (Refereed)
    Abstract [en]

    Polysaccharides of marine origin are gaining interest as biomaterial components. Bacteria derived from deep-sea hydrothermal vents can produce sulfated exopolysaccharides (EPS), which can influence cell behavior. The use of such polysaccharides as components of organic, collagen fibril-based coatings on biomaterial surfaces remains unexplored. In this study, collagen fibril coatings enriched with HE800 and GY785 EPS derivatives were deposited on titanium alloy (Ti6Al4V) scaffolds produced by rapid prototyping and subjected to physicochemical and cell biological characterization. Coatings were formed by a self-assembly process whereby polysaccharides were added to acidic collagen molecule solution, followed by neutralization to induced self-assembly of collagen fibrils. Fibril formation resulted in collagen hydrogel formation. Hydrogels formed directly on Ti6Al4V surfaces, and fibrils adsorbed onto the surface. Scanning electron microscopy (SEM) analysis of collagen fibril coatings revealed association of polysaccharides with fibrils. Cell biological characterization revealed good cell adhesion and growth on bare Ti6Al4V surfaces, as well as coatings of collagen fibrils only and collagen fibrils enhanced with HE800 and GY785 EPS derivatives. Hence, the use of both EPS derivatives as coating components is feasible. Further work should focus on cell differentiation.

    Airborne contamination and surgical site infection: Could a thirty-year-old idea help solve the problem?2019In: Medical Hypotheses, ISSN 0306-9877, E-ISSN 1532-2777, Vol. 132, article id 109351Article in journal (Refereed)
    Abstract [en]

    Surgical site infection (SSI) is a most serious postoperative complication, associated with increased morbidity and mortality, as well as extended therapy and elevated healthcare costs. In open clean surgery, e.g. orthopedic and cardiothoracic operations, the risk of SSI is strongly correlated with the amount of airborne bacteria being present in the operating room and the surgical field. The source of these bacteria is the surgical team itself, as we all emit thousands of bacteria-carrying skin particles every minute into the air. Although the risk of airborne contamination has decreased over the years, thanks to modern surgical clothing and advanced operating room ventilation, airborne bacteria are still detected and cause SSI. However, during the past thirty years there has been a simple and potentially effective preventive method waiting to be noticed. In 1986 Hall, Mackintosh and Hoffman found in a controlled experimental study that the application of regular unperfumed skin lotion to a person's body reduced the emission of airborne bacteria-carrying particles by approximately 90%. Moreover, the effect lasted at least 4 hours, which corresponds to a major surgical procedure. Thus, in the light of those results the present paper puts forth the hypothesis that this method can decrease the incidence of airborne bacterial contamination and SSI in open clean surgery. The paper also discusses the rationale and advantages of the method, and questions why it has escaped scientific attention for so long. In healthcare, difficult problems rarely have a simple and cheap solution. However, the use of ordinary skin lotion in open surgery may just be one, as it could potentially help prevent surgical site infection, and thereby increase patient safety and reduce healthcare costs.

    Feasibility of using a novel instrumented human head surrogate to measure helmet, head and brain kinematics and intracranial pressure during multidirectional impact tests2019In: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861Article in journal (Refereed)
    Abstract [en]

    Objectives: Aim of the work is to present the feasibility of using an Instrumented Human Head Surrogate (IHHS-1) during multidirectional impacts while wearing a modern ski helmet. The IHHS-1 is intended to provide reliable and repeatable data for the experimental validation of FE models and for the experimental evaluation of modern helmets designed to enhance the degree of protection against multidirectional impacts. Design: The new IHHS-1 includes 9 triaxial MEMS accelerometers embedded in a silicone rubber brain, independently molded and presenting lobes separation and cerebellum, placed into an ABS skull filled with surrogate cerebrospinal fluid. A triaxial MEMS gyroscope is placed at the brain center of mass. Intracranial pressure can be detected by eight pressure sensors applied to the skull internal surface along a transversal plane located at the brain center of mass and two at the apex. Additional MEMS sensors positioned over the skull and the helmet allow comparison between outer and inner structure kinematics and surrogate CSF pressure behavior. Methods: The IHHS-1 was mounted through a Hybrid III neck on a force platform and impacted with a striker connected to a pendulum tower, with the impact energies reaching 24J. Impact locations were aligned with the brain center of mass and located in the back (sagittal axis), right (90° from sagittal axis), back/right (45°), and front right (135°) locations. Following dynamic data were collected: values of the linear accelerations and angular velocities of the brain, skull and helmet; intracranial pressures inside the skull. Results: Despite the relatively low intensity of impacts (HIC at skull max value 46), the skull rotational actions reached BrIC values of 0.33 and angular accelerations of 5216 rad/s2, whereas brain angular acceleration resulted between 1,44 and 2,1 times lower with similar values of BrIC. Conclusions: The IHHS-1 is a physical head surrogate that can produce repeatable data for the interpretation of inner structures behavior during multidirectional impacts with or without helmets of different characteristics.

    Additive manufacturing to veterinary practice: recovery of bony defects after the osteosarcoma resection in canines2019In: BIOMEDICAL ENGINEERING LETTERS, ISSN 2093-9868, Vol. 9, no 1, p. 97-108Article, review/survey (Refereed)
    Abstract [en]

    The paper outlines the achievements and challenges in the additive manufacturing (AM) application to veterinary practice. The state-of-the-art in AM application to the veterinary surgery is presented, with the focus of AM for patient-specific implants manufacturing. It also provides critical discussion on some of the potential issues design and technology should overcome for wider and more effective implementation of additively manufactured parts in veterinary practices. Most of the discussions in present paper are related to the metallic implants, manufactured in this case using so-called powder bed additive manufacturing (PB-AM) in titanium alloy Ti-6AL-4V, and to the corresponding process of their design, manufacturing and implementation in veterinary surgery. Procedures of the implant design and individualization for veterinary surgery are illustrated basing on the four performed surgery cases with dog patients. Results of the replacement surgery in dogs indicate that individualized additively manufactured metallic implants significantly increase chances for successful recovery process, and AM techniques present a viable alternative to amputation in a large number of veterinary cases. The same time overcoming challenges of implant individualization in veterinary practice significantly contributes to the knowledge directly relevant to the modern medical practice. An experience from veterinary cases where organ-preserving surgery with 3D-printed patient-specific implants is performed provides a unique opportunity for future development of better human implants.

    Selective electron beam melting of Al0.5CrMoNbTa0.5 high entropy alloys using elemental powder blend2019In: Heliyon, ISSN 2405-8440, Vol. 5, no 2, article id e01188Article in journal (Refereed)
    Abstract [en]

    High Entropy Alloys (HEAs) is a novel promising class of multi-component materials which may demonstrate superior mechanical properties useful for high-temperature applications. Despite the high potential of HEAs, their production is complicated, using pre-alloyed powders in powder metallurgy route. This significantly complicates development and implementation of refractory BCC solid solution based HEAs. The present paper reports on experiments aiming at production of Al0.5CrMoNbTa0.5 multi-principle alloy using powder bed beam based additive manufacturing. Samples were manufactured using Selective Electron Beam Melting (SEBM) additive manufacturing technique from a blend of elemental powders aiming at achieving microstructure with high configurational entropy. Though it was not possible to achieve completely homogeneous microstructure, the as-printed material was composed of the zones with two multi-component solid solutions, which differed only by Al content confirming in situ alloying. The process parameters optimization was not carried out and the as-print material contained a notable amount of residual porosity. It was possible to reach lower porosity level using heat treatment at 1300 °C for 24 hours, however undesirable alloy composition changes took place. The main conclusion is that the production of the Al0.5CrMoNbTa0.5 multi-principle alloy from elemental powder blends using SEBM technique is achievable, but the process parameter optimization rather than post-process heat treatment should be performed to reduce the porosity of samples.

    Decreased bacterial colonization of additively manufactured Ti6Al4V metallic scaffolds with immobilized silver and calcium phosphate nanoparticles2019In: Applied Surface Science, ISSN 0169-4332, E-ISSN 1873-5584, Vol. 480, p. 822-829Article in journal (Refereed)
    Abstract [en]

    The design of an ideal bone graft substitute has been a long-standing effort, and a number of strategies have been developed to improve bone regeneration. Electron beam melting (EBM) is an additive manufacturing method allowing for the production of porous implants with highly defined external dimensions and internal architectures. The increasing surface area of the implant may also increase the abilities of pathogenic microorganisms to adhere to the surfaces and form a biofilm, which may result in serious complications. The aim of this study was to explore the modifications of Ti6Al4V alloy scaffolds to reduce the abilities of bacteria to attach to the EBM-manufactured implant surface. The layers composed of silver (Ag), calcium phosphate (CaP) nanoparticles (NPs) and combinations of both were formed on the EBM-fabricated metallic scaffolds by electrophoretic deposition in order to provide them with antimicrobial properties. The assay of bacterial colonization on the surface was performed with the exposure of scaffold surfaces to Staphylococcus aureus cells for up to 17 h. Principal component analysis (PCA) was used to assess the relationships between different surface features of the studied samples and bacterial adhesion. The results indicate that by modifying the implant surface with appropriate nanostructures that change the hydrophobicity and the surface roughness at the nano scale, physical cues are provided that disrupt bacterial adhesion. Our results clearly show that AgNPs at a concentration of approximately 0.02 mg/сm 2 that were deposited together with CaPNPs covered by positively charge polyethylenimine (PEI) on the surface of EBM-sintered Ti6Al4V scaffolds hindered bacterial growth, as the total number of attached cells (NAC) of S. aureus remained at the same level during the 17 h of exposure, which indicates bacteriostatic activity.

    Lifestyle Entrepreneurs within Nature-Based Businesses in Sweden2019Conference paper (Refereed)
    Abstract [en]

    A growing number of research studies focuses on lifestyle entrepreneurs in the tourism industry. Lifestyle entrepreneurs often start their business due to the fact that they want to make business of their hobby or they want to create a certain quality of life by living in a specific place. Previous studies argue that lifestyle entrepreneurs are often motivated by non-economic goals. Nature based businesses includes traditional businesses like agriculture and forestry but also new emerging businesses that are based on nature‟s resources like tourism. In rural areas, these type of tourism business are the most important incomes and therefore also of high importance concerning business development. The aim is to explore the tourism entrepreneurs‟ point of view of their lifestyle and business within nature based businesses in rural areas. The study was conducted with a qualitative approach. 17 different cases was studied from autumn 2015 until autumn 2016. The cases consisted of micro tourism companies within nature based businesses situated in the rural county of Jämtland in Sweden. The data was collected through semistructured interviews, observations and written materials. The result from this study show that there is several difference between tourism lifestyle entrepreneurs in rural areas with nature based businesses. We have identified four types of tourism lifestyle entrepreneurs that have different motives for running their businesses. The results also show that depending on what kind of tourism entrepreneur they focus differently on their nature based businesses. Many of the lifestyle entrepreneurs are focusing on finding several different types of income to spread the risk and also obtain growth. We could also see that traditional entrepreneurs within nature based businesses prefer to focus on the main income which often was more traditional products and services rather than tourism. The tourism lifestyle entrepreneurs therefore seem to try more different types of businesses and appear more open minded to create and innovate new products and services.

    Sustainability Information in Large-sized Companies in Europe: Does National Culture Matter?2019In: The International Journal of Sustainability in Economic, Social and Cultural Context, ISSN 2325-1115, E-ISSN 2325-114X, Vol. 15, no 1, p. 45-62Article in journal (Refereed)
    Abstract [en]

    This article focuses on sustainability information in large-sized companies in Europe. The aim of this article is to examine sustainability information in large-sized companies in European countries and the effect that the different national cultures might have on how sustainability is informed. The theoretical frameworks used are stakeholder theory, legitimacy, accountability, and national culture. The study has a qualitative approach, and data were collected during the spring of 2017 from 100 companies in five European countries (Finland, France, Germany, the Netherlands, and Sweden). Data were collected from websites, written documents, and other secondary sources. The results show that there are both differences between companies within each country and between countries. Companies in different countries focus on different aspects of sustainability in their information. The theoretical contribution this study makes is a model that can be used as a tool when discussing sustainability among large-sized companies in Europe. Practical implications include new knowledge of national differences between large-sized companies in how they work with sustainability, which could be of use to companies trying to enter other European markets.

    Tourism Entrepreneurs with Nature-Based Businesses in Sweden: The Role of the Lifestyle and the Place2019In: Athens Journal of Tourism, E-ISSN 2241-8148Article in journal (Refereed)
    Abstract [en]

    A growing amount of research focuses on lifestyle entrepreneurs in the tourism industry. Lifestyle entrepreneurs often go into business with the aim of making a hobby their income source or to create a certain quality of life in a specific place. Previous studies argue that lifestyle entrepreneurs are often motivated by noneconomic goals. Nature-based businesses include traditional businesses such as those in the agriculture and forestry industries as well as new emerging businesses that are based on nature’s resources such as tourism. In rural areas, these types of tourism businesses generate important income and are therefore of great importance from a business development perspective. The aim of this study is to explore how tourism entrepreneurs see their lifestyles and nature-based businesses in rural areas. The study was conducted using a qualitative approach. Seventeen different cases were studied between autumn 2015 and autumn 2016, all of which were nature-based businesses in the area of micro-tourism located in rural Sweden. Data were collected from semi-structured interviews, observations, and written material. The study’s results show that there are several differences between tourism-lifestyle entrepreneurs in rural areas with nature-based businesses. We have identified four types of tourismlifestyle entrepreneurs, each with different motives for running their businesses. The results also show that they focus differently on their nature-based businesses, depending on what kind of tourism entrepreneur they are. Many of the lifestyle entrepreneurs focus on developing several different types of income to reduce risk and obtain growth. Tourism-lifestyle entrepreneurs therefore seem to try different types of businesses and appear to be more open-minded and innovative where creating new products and services is concerned
