    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.

    Creating a Force of Development in Swedish Healthcare: A Contribution from the First-Line Managers’ Perspective When Driving Improvement Work Based on Lean2019Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis is about the healthcare managers, working at operational levels, defined as the first-line managers. These managers often are given the role and responsibility to integrate improvements into daily work. A stronger development ability of Swedish healthcare requires first-line managers with a developed ability to lead change. Thereby efforts must be made to provide these managers with supportive work conditions when leading and developing organizations. One approach to organizational development is Lean, which refers to a strong improvement culture based upon a supportive and highly engaged leadership as well as a strong customer focus. The purpose of this thesis is to contribute to knowledge about and an understanding of the conditions that influence first-line healthcare managers’ abilities to drive improvement work based on Lean. Some of the conditions investigated are; time, receiving support from the own manager, feeling joy in improvement work and being assured about the effects of Lean.

    The thesis is based on three separate analyses of a web-based survey, which relate to the two research questions. The study was conducted in a Swedish healthcare organization two years after the initiation of Lean. The analyses are presented in three separate papers. The first research question considers; How can an instrument be developed that investigates first-line managers’ views on their role, conditions and ability to drive improvement work based on Lean? The second question is; What can be learned from using the instrument that investigates first-line managers’ views on their role, conditions and ability to drive improvement work based on Lean? A qualitative study based on a hermeneutic, inductive, qualitative research approach was conducted in order to meet the research purpose and answer the research questions.

    The thesis is mainly based on three papers. In paper 1 it is stated that the assuredness about the effects of Lean was quite high among the managers when the survey was conducted, such as that Lean contributes to a greater patient focus and to the development of an improvement culture. In paper 2 it is noted that the first-line managers view their role as crucial in improvement work based on Lean. Time, support from coworkers, and a clear vision and clear goals were the three conditions they considered to be most important for their ability. The results presented in paper 3 show that to initiate improvement work based on Lean, they ask for own managers who are assured about Lean and include them in discussions. They view their role and responsibility in relation to their coworkers as extensive, for instance increating a culture where problems and mistakes are viewed as possibilities to improve and for encouraging that new work procedures are tested. The findings indicate a need for a deeper understanding of Lean. It is concluded that a thorough understanding of Lean is a main condition for the first-line managers´ ability to drive improvement work based on the approach. Developing a common view of Lean takes time, which is important to emphasize in the practical setting to motivate for a long-term perspective. This development takes highly motivated, assured and persistent leaders with a continuous improvement attitude and a mission to improve healthcare together.

    There is also an applied research question; How can the use of the instrument contribute to developing first-line managers’ role, conditions, and ability to drive improvement work based on Lean? In its essence, Lean is concerned with improving a system and since the instrument raises questions about relationships between organizational members, it sets focus on the system and calls on a system view. The responsibility for one management level must continuously be set I relation to another, when putting the pieces together in the “improvement puzzle”. Change depends on adjustments in human behavior and the instrument establishes a focus on the people in the processes necessary for development and results. The instrument also provides opportunity and structure to investigate and talk about the soft conditions important for the ability, such as receiving support from the own manager, and feeling inspiration and being assured. The practice of Lean requires changes in attitudes, new habits, new skills in the whole system, meaning in each individual from the executive management to the front-line workers. Thereby self-reflection becomes important, which requires forums for dialogue. It is concluded that such forums can influence first-line healthcare managers’ abilities to drive improvement work based on Lean. In dialogue forums improvement work can be reflected upon and learned from together.

    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.

    Värdeskapande intern kommunikation med Lean kommunikation och kommunikativt ledarskap: Modell för Lean kommunikation för att stärka och medvetet arbeta med värdeskapande intern kommunikation i Leanbaserade verksamheter,2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The    purpose of this study was to explore how Lean based/Lean inspired    enterprises in Swedish public sector acts to attain value-adding internal    communication. The starting point was that the contemporary demographic    development combined with demands for cost-effectiveness entail challenges    for municipalities to safeguard welfare and customer satisfaction, and that    this task needs to start internally towards the employees in order to bring    effects externally towards the customers. Lean communication and    communicative leadership has arisen as two relatively new concepts which    have not yet been extensively explored, but which aim precisely at    value-adding communication. This study focussed on these two concepts at a    theoretical level and explored how they can be utilised practically and    strategically in order to improve value-adding internal communication. The    empirical data consisted of semistructured interviews with 15    managers/leaders from six municipalities, which have been analysed with qualitative    content analysis. The conclusion was that there existed a relatively    substantial congruity between the respondents concerning what was considered    success factors, what distinguishes a good communicative leader and how they    handled internal communication in the daily work. Clarity and visualisation    were the most frequently aspects mentioned. Additionally, the linkage to    Lean communication and communicative leadership was palpable – even though    not all of the respondents were familiar with or used the concepts, they    were utilising them subconsciously. However, only a minority of them had    functioning strategies to facilitate leaders to be more communicative and    several of them acknowledged shortcomings concerning follow-up, evaluation    and feedback. Based on the study’s results, a model for Lean communication    was created – with a checklist attached – which can be deployed by Lean    enterprises in order to strengthen and consciously work with value-adding    internal communication.

    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.

    Skolans om lärande organisation: En studie   av PRIO och dess effekter i ett hållbart utvecklingsarbete2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Purpose: The purpose of this study was to develop   more knowledge about the school as a learning organization.

    Design: A qualitative case study was conducted, where   the improvement program PRIO and its effects on the schools in Landskrona were   studied. The aspects implementation, long term improvement, the effects of   PRIO in the schools today, increase of quality for the students and the   connection between the schools' development spheres and the research field of   learning organizations in general were examined.

    Findings: The conclusion was that the implementation   was successful in the initial phase, but that the improvement then faded in   more than half of the schools. This can partly be linked to large staff turnover   among the principals, but also to the fact that in many cases the PRIO work   has not been part of the schools' systematic quality management. The schools   experiences an increase of quality for the students, but the connection to   PRIO is not entirely evident. More than half of the development spheres that   the schools have worked with correlate with the spheres highlighted as   essential in the research field around learning organizations. The schools   developed a learning organization through the PRIO work, but not all schools   have been able to maintain it over time.

    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 1878-1861, Vol. 22, no S1, p. S78-S84Article 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.

    Production of net-shape Mn-Al permanent magnets by electron beam melting2019In: Additive Manufacturing, ISSN 2214-8604, Vol. 30, article id 100787Article in journal (Refereed)
    Abstract [en]

    The main goal of this work is the adoption of additive manufacturing for the production of inexpensive rare-earth free MnAl-based permanent magnets. The use of more advanced binder-free additive manufacturing technique such as Electron Beam Melting (EBM) allows obtaining fully-dense magnetic materials with advanced topology and complex shapes. We focus on the feasibility of controlling the phase formation in additively manufactured Mn-Al alloys by employing post-manufacturing heat treatment. The as-manufactured EBM samples contain 8% of the desired ferromagnetic τ-MnAl phase. After the optimized annealing treatment, the content of the τ-phase was increased to 90%. This sample has a coercivity value of 0.15 T, which is also the maximum achieved in conventionally produced binary MnAl magnets. Moreover, the EBM samples are fully dense and have the same density as the samples produced by conventional melting density.

    ”Vispelar alltid på varandras bästa fot”: En studieom Appreciative Leadership och de fem kärnstrategiernas praktik2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In a society   which demands rapid change, exploring and defining which factors build up a   long-term sustainable organisation with prosperous and flexible employees is   important. Appreciative leadership is a leadership philosophy which can be   split into five core strategies. (5 I) These strategies strongly correlate   with what is described in the literature as ”health factors” in the work   environment. The purpose of this study was to discover how the five core   strategies can be put in to practice and to explore what effect this has on   the psychosocial work environment. The study used mixed methods and the   result is based on a quantitative questionnaire that was followed up by   qualitative in-depth interviews and focus group. The basis for the result was   also general observation and a brief literature review. The result showed   that all five core strategies were present in the organization and that all   em-ployees described their psychosocial environment as excellent. It was also   noticed that the practice of the five core strategies in the organization   takes place through a number of well-chosen methods, including a strong   supportive culture, internal leadership and clear communi-cation. The result   also revealed that there were challenges with the actual way of working and   that there were some basic conditions that were described as important for   the method as a whole. These included high staffing and strong common values.   The practice of the core stra-tegies were described as contributing to the   health factors of working. It was concluded that it is highly likely that a   conscious practice of 5 I can contribute to a healthy work place, increase   work satisfaction and in the long term decrease the risk for work-related   illness.

    Utvärdering på distans: En Action Research-ansats för förbättring av e-learningverktyg i ettinternationellt handelsföretag2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The   purpose of this paper was to design and test a model for evaluation of an   e-learning program in large, international retail company. The size of the   organization and the distance between many of it’s divisions and units, meant   that it for practical reasons was difficult to perform qualitative   evaluations. Many co-workers had low confidence in the organization’s ability   to receive and absorb their feedback. As an attempt to adjust the evaluation   to these premises without losing the dimension of qualitative assessment one   can have in a live meeting, a model for evaluation, based on communication   via video link, was designed. The model contained prepared, structured   workshops leading to a video link meeting with the developer of the   trainings. In this meeting, feedback was given, follow-up questions were   asked and discussions held. The model was based on working methods and   philosophy within the Total Quality Management framework. The research   method was an adaption of “Action Research”, a method based on the active   participation of the researcher and in which obtained results and reflections   made during the process, will influence the upcoming course of actions. The   results were positive and showed that aspects of Total Quality Management such   as inclusion and engaged leadership had great impact on how the   co- workers perceived the process of change. The conclusion was that the   model was an improvement of the existing feedback-process and that it also   created a higher level of perceived engagement amongst participating   co-workers and managers.

    Tillämpningav SIQ Managementmodell i SME: Tillämpningav SIQ Managementmodell i SME2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This research is based on the future challenge of   increasing knowledge about quality development and highlights this both as a   management question and a strategic ownership issue. This from a SME   perspective that has limited resources and knowledge to take on quality   development.

    The study aims to increase understanding of how   quality development, with the help of SIQ Management model, can contribute to   a sustainable performance development within an SME, with experience of   quality management systems through ISO 9001.

    This study is based on a qualitative case study of   an SME. Initially, literature research and design of a workshop took place   focusing on SIQ Management model in the form of a presentation and discussion   for a focus group. Subsequently, data collection was carried out the workshop   through both individual and group interviews and observations.

    The results of the study show an increased   understanding of quality development through a proven awareness of the   employees. With the help of SIQ Management model, a previous deterministic   approach to quality could be made consciously to allow for a more dynamic   approach. The participants became aware of a possible sustainable performance   development and a focus on process development, which requires participation   for successful work. The participants decided that this would be the next   step in the development work.

    For the firm that constituted the case study, the   workshop generated a foundation on which to start a quality development work.   It also created an awareness of areas for improvement that both management   and employees can work further with.

    Är kinesisk produktkvalitet bättre än svensk år 2025?2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    China has through various government initiatives started a quality   race with the ambition to take Chinese product quality to higher levels until   2025. If they succeed, Swedish companies that trade/ compete with Chinese   companies, or conduct business within China, are likely to be affected. The   question is how? The purpose of this study has been to check the pulse of   Swedish companies; how do they perceive the Chinese quality development and   how do they think their company will be affected? An underlying purpose has   been to investigate how cultural aspects affect the Chinese quality   development. To answer this, a quantitative survey was conducted aimed at   Swedish quality managers and a qualitative case study aimed at Swedish   companies with a presence in China. The result shows that the level of   Chinese product quality is expected to rise in many industries, and that   competition and trade exchange will be affected by increasing Chinese market   shares in the global market. In some areas, Chinese product quality is   already equivalent to Western, but it is not stable but requires controls   from the recipient, namely the customer. A likely contributing factor to the   uneven quality is found in the Chinese macro culture where traditionally one   prides itself on performing tasks according to orders and not questioning   superiors. This has a negative effect on the quality culture, which in turn   risks making quality development more difficult and is a challenge for China   to handle. Despite this challenge, this study shows that it is possible that the   Chinese state's initiative may succeed, at least in large part, and both   Swedish companies and the global market should keep a watchful eye on   developments.

    Faktorer som hindrar respektive möjliggör etablering av en förbättringskultur: En jämförelse mellan två olika svenska branscher2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Continuous   improvements are something most companies, regardless of industry, say they   work with. However, the industries have different conditions when it comes to   work on continuous improvement. Some industries have businesses that are   easier to control as, for example, when production takes place in one and the   same place, while other businesses find it more difficult to control the   business since they have production in several different places. The purpose   of this study has been to study how companies in two different industries   with different conditions can work in order to create an improvement culture   that engages the employees in the work with continuous improvement and which   factors in an organizational culture that enable or hinder the work with   this. To do this, two case studies were carried out at two selected companies   in the construction and production industry. The data collection consisted of   qualitative semi-structured interviews with professional workers. The data   processing was performed with the help of Släktskapsdiagram that were created   individually for the two companies. Similarities and differences between the   two companies were analyzed to answer the study's purpose.

     

    The   result of the study shows that factors that prevent or enable an improvement   culture, for both companies in the study, have clear links to previous   knowledge in the field. The identified factors consisted of; Company,   Communication, Motivation, Employee, Leadership, Participation, Attitude.   These factors can act both as a hindrance and as a means of enhancing the   improvement work and thus have great importance for how well an improvement   work works in a workplace. The factors of communication participation are two   specific areas that both the two companies in the study need to work more   with to create a strong culture of improvement.

    Framgångsfaktorer vidförvaltningsöverskridande kvalitetsarbete inom kommunal verksamhet: Styrkebaserade intervjuer med tjänstemän2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the public sector, large resources are invested annually on   quality-enhancing work. Nevertheless, the outcome is rarely what was   intended. The reasons for this are partly

    known. Bureaucracy, regulatory control and a hierarchical   function-oriented organization building, where responsibility and   decision-making are distributed

    among several individuals, lead to a lack of holistic view. The   customers are many and as a group heterogeneous, in addition, the perception   of their needs may differ

    within the organization. Furthermore, differences in norms, working   methods and methods complicates the interaction between different   administrations. Based on the challenges and lack of research, there is a   need for increased knowledge of how success can be achieved in quality work   involving several administrations. The purpose of the study was to create   insight into what constitutes success factors in

    municipal quality work involving multiple administrations.   Semi-structured, strengthbased interviews with seven officials from four   municipalities were conducted. All of

    them had experience of successful quality work which involved more   than one administration. The interviews were transcribed verbatim and   analyzed with content

    analysis. In the analysis, five overarching themes were identified:   Common image, Structure, Encouraging leadership, Exit the framework and Power   balance. The study may be of interest to Sweden's municipalities as it shows   what can be success factors in municipal, quality work involving more than   one administration.

    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

    Leda kvalitetsarbetet för en hållbar framtid: Kvalitetschefens roll, kompetens och utveckling isvenska företag och organisationer2019Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In successful quality management, the role and competence of the quality manager is of importance. Previous studies show that the role is ambiguous and relatively few are educated on a university level. This study seeks to contribute to the knowledge and understanding of the success factors and the development of role and competence of the quality manager the last decade. Quality managers in public-, private- and non-profit sector was selected that as of today works as a quality manager. The working procedure remained of six phases: literature review, pilot study, questionnaire design, survey management and data collection and analysis. To analyze the result, a method of a multiple stepwise regression analysis and affinity diagram was used. The result shows that the competence of the quality manager lays within 12 identified areas and the role operates within five areas of a quality manager and quality management. The role appears as clear in smaller organizations where there is a committed leadership, possibilities for competence development and a collaboration with customers and suppliers. To succeed, the management's commitment and personal capacity are important. Leading for sustainable development, is a field of work that has been identified as part of the role. Most of the quality managers sit in the management group, where factors that contribute to whether the quality manager influences strategic decisions and goals in organizations are whether they are in the management group where they can influence decisions.

    The education level of the quality manager has not increased significantly the past few years which leads to the conclusion that quality managers holds the required skills for the work. The competence consists of knowledge and experience and of formal and non-formal education. Education, competence and commitment within the management are factors that stick together and affect each other.
