    Oförändrad insulinkänslighet och lipidperoxidation efter ökat intag av fullkornsprodukter hos friska män och kvinnor.2006Inngår i: Livsmedelsforskardagarna, 2006Konferansepaper (Annet (populærvitenskap, debatt, mm))
    Abstract [en]

    Flertalet epidemilogiska studier har visat positiva hälsoeffekter av ett högt intag av fullkornsprodukter. Framförallt är en minska risk för hjärtinfarkt/sjukdom visad, och data

    talar även för en minskad risk för typ 2 diabetes. Mekanismerna bakom fullkornets positiva effekter är dock fortfarande oklara. Såväl en förbättrad insulinkänslighet som en minskad förekomst av lipidperoxidation och inflammation har föreslagits, vilket vi därför önskade undersöka i denna studie.

    I en randomiserad cross-over design deltog 30 lätt överviktiga (BMI 282) kvinnor (n=22) och män (n=8). Under två på varandra följande 6 veckors perioder fick deltagarna antingen cerealieprodukter med fullkorn eller utan fullkorn. En standardiserad mängd (3 skivor mjukt bröd, 2 skivor hårt bröd, 1 portion musli/gryn och 1 portion pasta/ris) inkluderades dagligen i deras vanliga kost. Perifer insulinkänslighet mättes med euglykemisk hyperinsulinemisk clampteknik. Lipidperoxidationsmarkören 8-iso-PGF2 mättes i urin och inflammationsmarkörerna CRP och IL-6 mättes i plasma. Kostinterventionen monitorerades med hjälp av vägda kostregisteringar och dagboksnoteringar.

    Kostregistreringarna bekräftade ett högre intag av fiber och flertalet mineralämnen under fullkornsperioden jämfört med icke-fullkornsperioden. Vi fann dock ingen förbättring av insulinkänsligheten och inte heller någon förändring av lipidperoxidation eller inflammationsmarkörer.

    Att ersätta icke-fullkorns produkter med fullkorn under en 6 veckors period hos vuxna lätt överviktiga friska män och kvinnor gav således ingen mätbar effekt på vare sig insulinkänslighet, lipidperoxidation eller inflammationsmarkörer. Frågan om vilka mekanismerna som ligger bakom de positiva hälsoeffekterna av fullkornsprodukter kvarstår och längre koststudier på deltagare med varierande metaboltstatus behövs.

    Lack of trophic polymorphism despite substantial genetic differentiation in sympatric brown trout (Salmo trutta) populations2017Inngår i: Ecology of Freshwater Fish, ISSN 0906-6691, E-ISSN 1600-0633, Vol. 26, nr 4, s. 643-652Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Sympatric populations occur in many freshwater fish species; such populations are typically detected through morphological distinctions that are often coupled to food niche and genetic separations. In salmonids, trophic and genetically separate sympatric populations have been reported in landlocked Arctic char, whitefish and brown trout. In Arctic char and brown trout rare cases of sympatric, genetically distinct populations have been detected based on genetic data alone, with no apparent morphological differences, that is cryptic structuring. It remains unknown whether such cryptic, sympatric structuring can be coupled to food niche separation. Here, we perform an extensive screening for trophic divergence of two genetically divergent, seemingly cryptic, sympatric brown trout populations documented to remain in stable sympatry over several decades in two interconnected, tiny mountain lakes in a nature reserve in central Sweden. We investigate body shape, body length, gill raker metrics, breeding status and diet (stomach content analysis and stable isotopes) in these populations. We find small significant differences for body shape, body size and breeding status, and no evidence of food niche separation between these two populations. In contrast, fish in the two lakes differed in body shape, diet, and nitrogen and carbon isotope signatures despite no genetic difference between lakes. These genetically divergent populations apparently coexist using the same food resources and showing the same adaptive plasticity to the local food niches of the two separate lakes. Such observations have not been reported previously but may be more common than recognised as genetic screenings are necessary to detect the structures.

    Adjuvant and Down-Staging Treatment with Imatinib in Gastrointestinal Stromal Tumours2008Independent thesis Advanced level (professional degree), 10 poäng / 15 hpOppgave
    Abstract [en]

    Background: GISTs are gastrointestinal mesenchymal tumours that express the type III receptor tyrosine kinase KIT. The KIT proto-oncogene encodes the receptor KIT. Most GISTs have gain-of-function mutations in the KIT or PDGFRA gene. The tyrosine kinase is therefore continuously activated leading to ligand-independent dimerization. Imatinib mesylate (Glivec®) is considered to be the first-line palliative treatment. The activated form of the KIT receptor tyrosine kinase is inhibited by imatinib. The aim of the study was to compare the survival of patients treated with either adjuvant or down-staging imatinib with historic controls treated with radical surgery (R0) only.

    Methods: A historic control group was chosen from a population-based series from western Sweden (population 1.6 million) that matched the adjuvant (n=23) and down-staging (n=7) groups respectively. Mutation analysis was performed in all cases with bidirectional direct sequencing. The recurrence-free survival was calculated.

    Results: There was only one recurrence (4 %) in the adjuvant group, and no recurrences in the down-staging study group, compared to 32/48 patients (67 %) in the control group. Tumour size decreased in diameter from 20 cm to 11 cm with down-staging treatment.

    Conclusion: Adjuvant imatinib improves recurrence-free survival in R0 resected patients. Down-staging treatment with imatinib is recommended for patients with large tumours or metastases. The importance of mutation analysis was established.

    The adhesion of Bacillus cereus spores to epithelial cells might be an additional virulence mechanism1998Inngår i: International Journal of Food Microbiology, ISSN 0168-1605, E-ISSN 1879-3460, Vol. 39, nr 42006, s. 93-99Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Four out of ten Bacillus cereus strains produced spores able to adhere to monolayers of Caco-2 cells (human epithelial cells). One of these strains has been involved in an outbreak of food poisoning where the symptoms were more severe and persisted for longer than a normal B. cereus food poisoning. The hydrophobicity of the spores is a contributing factor for the adhesion to occur. The spores are able to germinate in an environment similar to that of the small intestine and then the vegetative cells can produce the enterotoxin directly at the target place. A concentrated and active form of the enterotoxin will be taken up by the epithelial cells in the small intestine. Spore adhesion could be an important virulence factor for some B. cereus strains.

    Adhesion and removal of dormant, heat-activated, and germinated spores of three strains of Bacillus cereus1998Inngår i: Biofouling (Print), ISSN 0892-7014, E-ISSN 1029-2454, Vol. 13, nr 1, s. 51-67Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As the spores of Bacillus cereus are known to be very adhesive, the cleaning processes used to eliminate them are often inefficient. This study investigated how adhesion and removal of spores varied among strains of the species B. cereus. The adhesion and removal of spores during their life cycle were also examined. Spores of three different strains of B. cereus, viz. NVH 61, 1AM 1110 and NCTC 2599, were used. IAM 1110 spores adhered in greater numbers than spores of the other two strains and were the most hydrophobic; four times as many spores of this strain adhered than of the least adhesive spores, NCTC 2599. Spores of both these strains have an exosporium and appendages, but as the relative hydrophobicity varies, there are probably differences in their chemical composition. It was also found that dormant spores were 33-48% more adhesive than germinated spores. There were no obvious differences in adhesion between dormant and heat-activated spores. Up to 80% of the germinated spores could be removed from the surfaces tested. Dormant and heat-activated spores on the other hand were difficult to remove from the surfaces. When siliconized glass surfaces were coated with milk, germinated spores were still the easiest to remove but the difference was not as marked as before. Therefore, this work suggests that cleaning processes should take into consideration factors that boost spore germination in order to improve the cleaning.

    Abstract [en]

    Spore-forming Bacillus cereus and Clostridium perfringens bacteria are special problems for the dairy and meat industry, respectively. Proper cleaning and disinfection with hypochlorite is essential to avoid high numbers of these bacteria in food products. It is impossible for B. cereus and C. perfringens to cause food poisoning with cooking and rapid cooling, and proper reheating. It is also important to note that the generation time for C. perfringens can be as short as 8 min under optimal conditions, so temperatures between 10 and 47 °C in any meat product must be restricted. B. cereus food poisoning through milk and milk products can be avoided with a low number of spores in the products and proper cooling.

    Comparison between automatic ribotyping and random amplified polymorphic DNA analysis of Bacillus cereus isolates from the dairy industry1999Inngår i: International Journal of Food Microbiology, ISSN 0168-1605, E-ISSN 1879-3460, Vol. 47, nr 42006, s. 147-151Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Discrimination by automatic ribotyping and random amplified polymorphic DNA PCR, RAPD, was compared for 40 different B. cereus dairy isolates, 4 different B. mycoides isolates and 6 culture collection strains. RAPD-PCR has previously shown to be useful for tracing contamination routes of B. cereus to milk. Automatic ribotyping using EcoRI and PvuII separated the B. cereus and B. mycoides isolates/strains into 36 different ribotypes. RAPD-typing with primers generated 40 different RAPD-profiles. However, 17 isolates clustered into eight groups, irrespective of the primer and restriction enzyme used, and in all but one case, the isolates with the same pattern were isolated from the same dairy. Automatic ribotyping proved to be a useful, standardized and quick method to discriminate between B. cereus strains, only slightly less discriminatory than RAPD-typing.

RAPD-PCR has previously shown to be useful for tracing contamination routes of B. cereus to milk. Automatic ribotyping using EcoRI and PvuII separated the B. cereus and B. mycoides isolates/strains into 36 different ribotypes. RAPD-typing with primer 1 (5?-CCGAGTCCA-3?) and primer 2 (5?-CCGGCGGCG-3?) generated 40 different RAPD-profiles. However, 17 isolates clustered into 8 groups, irrespective of the primer and restriction enzyme used and in all but one case, the isolates with the same pattern were isolated from the same dairy. To conclude RAPD-typing was only slightly more discriminatory than automatic ribotyping and therefore automatic ribotyping proved to be a useful, standardized and quick method to discriminate between B. cereus strains. As the two methods are based on completely different genetic properties, one of the methods can be used to confirm the results from the other method, when identity among isolates needs to be verified.

    Utvärdering och utveckling av Fiskarhedens Trävaru AB:s traktdirektiv för slutavverkning2018Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Bruttoavverkningen har accelererat de senaste decennierna och i takt med detta har kraven inom skogsbruket ökat. Idag behöver en omfattande miljöhänsyn tas. Detta ställer även högre krav på entreprenörerna. För att entreprenörerna ska klara av att leva upp till kraven är det viktigt att beställaren av tjänsten överlämnar en arbetsinstruktion i samband med avropande av traktuppdrag. Denna arbetsinstruktion och arbetsorder skapas i form av ett traktdirektiv. Ett kvalitativt traktdirektiv betraktas vara viktigt för Fiskarhedens Trävaru AB och för deras entreprenörer. En fallstudie har genomförts för att utvärdera och beskriva företagets nuvarande traktdirektiv. Resultatet visar att dagens traktdirektiv stundtals är bristfälliga genom att de är dåligt ifyllda. Viktigt innehåll kommuniceras därmed ej som det behövs. Ett förslag på nytt, förbättrat traktdirektiv, där innehållet är tänkt att fyllas i bättre, har därför tagits fram. Med hjälp av detta traktdirektiv kan Fiskarheden upprätthålla ett hållbart skogsbruk.

    Bilateral deficit vid excentrisk och koncentrisk muskelaktion: En jämförande studie mellan den summerade unilaterala och bilaterala kraftutvecklingen hos roddare visavi sprinters2006Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Aim

    The main aim of the study was to investigate the difference in bilateral deficit between rowers and sprinters during maximal eccentric/concentric muscle actions.

    • Are there any significant differences in bilateral deficit between rowers and sprinters?

    • Do the amount of years in practice effect the bilateral deficit?

    Method

    Fourteen male subject participants divided in 2 equal sized groups (7 individuals in each group; rowers and sprinters) performed maximal unilateral/bilateral eccentric and concentric muscle actions in a leg press machine at a velocity of 0.2m/s. The range of motion in the knee joint was 70° – 140°. Dependent t-tests have been performed within each group pre and post test. P was set to 0,05 to prevent type I faults (false positive) a Bonferroni test was made for two comparisons and set to 0,0253.

    Results

    Average bilateral deficit for rowers were: 11% concentric and 33% eccentric. Number of years in practice and bilateral deficit: practiced >8years concentric 7% and eccentric 24%. Practiced <8 years concentric 21% and eccentric 55%.

    Average bilateral deficit for sprinters were: 5% concentric and 24% eccentric. Number of years in practice and bilateral deficit: practiced >8years concentric 4% and eccentric 26%. Practiced <8years concentric 16% and eccentric 11%.

    Conclusions

    The main explanation for the larger differences in bilateral deficit for rowers in eccentric muscle action compared to sprinters may be related for the fact that the rowers have an almost non - eccentric phase during rowing. When comparing the amount of years in practice and bilateral deficit we saw that it decreased with the number of practiced years for booth rowers and sprinters. The reason to this pattern is probably on a neural base.

    Adaptation to climate change?: Why business-as-usual remains the logical choice in Swedish forestry2018Inngår i: Global Environmental Change, ISSN 0959-3780, E-ISSN 1872-9495, Vol. 48, s. 76-85Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The two latest IPCC assessment reports have concluded that knowledge is not sufficient for inducing action on climate change. This study problematizes the issue of going beyond business-as-usual through a study of the forestry sector in Sweden, which is a large economic sector and could be expected to be an early adapter, given that newly planted forest may stand some 70-90 years into the future. Therefore resources, economic motivation in the longer term and environmental foundations for early adaptation action could be expected to exist. This study draws upon the Foucauldian conceptualization of governmentality to explain the particular institutional logics that nevertheless lead to business-as-usual arguments dominating discussion on adaptation in the case of Swedish forestry. The study emphasizes that adaptation must be seen as steered and limited by existing institutional, social system logics, rather than by externally defined "rational" motivations. Efforts on adaptation to climate change must thus be considered in relation to, and seek to change, existing institutionally based motivational and incentive structures, and must thus be conceived through social rather than environmental logics. In fact, social logics may even define the types of actions that may be regarded as adaptations.

    In the eye of the storm: adaptation logics of forest owners in management and planning in Swedish areas2018Inngår i: Scandinavian Journal of Forest Research, ISSN 0282-7581, E-ISSN 1651-1891, Vol. 33, nr 8, s. 800-808Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    With a changing climate, storm and wind throw is becoming an increasing risk to forest. However, Swedish forest management practices have so far involved relatively little consideration of adaptation to climate change. This study examined resistance and alternatives to business as usual forest management, drawing upon material obtained in interviews with individual forest owners who spontaneously identified and discussed storm and wind throw as a risk to their forest. They thereby expressed a logic differing from that of the forest industry in Sweden, which has largely normalised storm risk rather than considering it in climate change adaptation work. The present analysis illustrates the broad and largely concerned position of individual forest owners, in contrast with a more established industry position on storm as an accepted and existing risk. Overall, the study highlights the diversity, agency and power relations within Swedish forestry and the forested landscape - aspects that are vital to better understanding processes relevant to forest and climate change adaptation.

    Adaptation to climate change in forestry: a perspective on forest ownership and adaptation responses2017Inngår i: Forests, ISSN 1999-4907, E-ISSN 1999-4907, Vol. 8, nr 12, artikkel-id 493Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Adaptation to climate change has often been discussed from the perspectives of social vulnerability and community vulnerability, recognising that characteristics at local level will influence the particular adaptations undertaken. However, the extent to which national-level systemic factors influence and shape measures defined as adaptations has seldom been recognised. Focusing on adaptation to climate change in forestry, this study uses the example of two countries in the northern hemisphere with different forest ownership structures, forestry industry and traditions: Sweden, with strong private, non-industrial ownership, dominant forest industry and long forestry traditions; and Scotland, with forest ownership dominated by large estates and investment forestry based on plantations of exotic conifer species. The study shows how adaptation to climate change is structurally embedded and conditioned, which has resulted in specific challenges and constraints for different groups of forest owners within these two different contexts. This produces a specific set of political spaces and policy tools by rendering climate change in relation to forestry manageable, negotiable and practical/logical in specific ways. It is recommended that the focus of future work on climate-related issues and development of adaptation measures and policy should not be primarily on climate-related factors, but on institutional analysis of structural factors and logics in target sectors, in order to critically explore concepts of agency and power within these processes.

    Memory carriers and stewardship of metropolitan landscapes2016Inngår i: Ecological Indicators, ISSN 1470-160X, E-ISSN 1872-7034, Vol. 70, s. 606-614Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    History matters, and can be an active and dynamic component in the present. We explore social-ecological memory as way to diagnose and engage with urban green space performance and resilience. Rapidly changing cities pose a threat and a challenge to the continuity that has helped to support biodiversity and ecological functions by upholding similar or only slowly changing adaptive cycles over time. Continuity is perpetuated through memory carriers, slowly changing variables and features that retain or make available information on how different situations have been dealt with before. Ecological memory carriers comprise memory banks, spatial connections and mobile link species. These can be supported by social memory carriers, represented by collectively created social features like habits, oral tradition, rules-in-use and artifacts, as well as media and external sources. Loss or lack of memory can be diagnoses by the absence or disconnect between memory carriers, as will be illustrated by several typical situations. Drawing on a set of example situations, we present an outline for a look-up table approach that connects ecological memory carriers to the social memory carriers that support them and use these connections to set diagnoses and indicate potential remedies. The inclusion of memory carriers in planning and management considerations may facilitate preservation of feedbacks and disturbance regimes as well as species and habitats, and the cultural values and meanings that go with them.

    Measuring social – ecological dynamics behind the generation of ecosystem services2007Inngår i: Ecological Applications, ISSN 1051-0761, E-ISSN 1939-5582, Vol. 17, nr 5, s. 1267-1278Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The generation of ecosystem services depends on both social and ecological features. Here we focus on management, its ecological consequences, and social drivers. Our approach combined (1) quantitative surveys of local species diversity and abundance of three functional groups of ecosystem service providers (pollinators, seed dispersers, and insectivores) with (2) qualitative studies of local management practices connected to these services and their underlying social mechanisms, i.e., institutions, local ecological knowledge, and a sense of place. It focused on the ecology of three types of green areas (allotment gardens, cemeteries, and city parks) in the city of Stockholm, Sweden. These are superficially similar but differ considerably in their management. Effects of the different practices could be seen in the three functional groups, primarily as a higher abundance of pollinators in the informally managed allotment gardens and as differences in the composition of seed dispersers and insectivores. Thus, informal management, which is normally disregarded by planning authorities, is important for ecosystem services in the urban landscape. Furthermore, we suggest that informal management has an important secondary function: It may be crucial during periods of instability and change as it is argued to promote qualities with potential for adaptation. Allotment gardeners seem to be the most motivated managers, something that is reflected in their deeper knowledge and can be explained by a sense of place and management institutions. We propose that co-management would be one possible way to infuse the same positive qualities into all management and that improved information exchange between managers would be one further step toward ecologically functional urban landscapes.

    Urinary incontinence: prevalence, treatment seeking behaviour, experiences, and perceptions among persons with and without urinary leakage2009Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The overall aim of this thesis is to describe urinary incontinence (UI) from a population perspective and to describe experiences and perceptions of UI from an individual perspective. This includes assessing the prevalence of urinary incontinence as well as describing treatment seeking and experiences of living with UI. A secondary aim was to describe the perception of UI among cultures other than the Swedish mainstream, exemplified in this case by Syrian women living in Sweden. Both quantitative and qualitative methods were used, including questionnaires and interviews.

    Studies I and II were quantitative studies based on a population-based study. Together with a postal survey on general health and living conditions “Life & Health”, a questionnaire on urinary incontinence was sent out to 15 360 randomly-selected residents aged 18-79 in Orebro County, Sweden. In Study I, UI was found to affect 19%. The majority of the respondents experienced minor problems, and only 18% of those reporting UI wanted treatment. However, there was also a group who reported severe problems, but despite this 42% of them did not want treatment. Study II investigated why people with UI refrain from seeking care and treatment. It was found that the desire for treatment was regulated by the frequency of UI, being restricted from participating in various activities, the degree of inconvenience, and the type of UI.

    Studies III and IV were both qualitative interview studies, describing older women’s experiences of living with UI (Study III) and Syrian women’s perceptions of UI (Study IV). There were similarities between the results of these two studies; the women described UI as a normal and expected problem, and they knew that the district nurse could prescribe incontinence protections and that treatments existed. In both studies, the women expressed difficulties in making contact with the health care service, while the women who did not speak Swedish (Study IV) also had difficulties due to different communication problems.

    In conclusion, it is important that health care resources are optimized to identify and meet the needs of those who experience major problems with UI, and that there is awareness of the communication difficulties that can be present in meeting with people who speak other languages. However it is also important not to medicalize those who experience minor problems and who have the desire to manage on their own.

    Effects of molecular weight on permeability and microstructure of mixed ethyl-hydroxypropyl-cellulose films2013Inngår i: European Journal of Pharmaceutical Sciences, ISSN 0928-0987, E-ISSN 1879-0720, Vol. 48, nr 42006, s. 240-248Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Films of ethyl cellulose (EC) and water-soluble hydroxypropyl cellulose (HPC) can be used for extended release coatings in oral formulations. The permeability and microstructure of free EC/HPC films with 30% w/w HPC were studied to investigate effects of EC molecular weight. Phase separation during film spraying and subsequent HPC leaching after immersion in aqueous media cause pore formation in such films. It was found that sprayed films were porous throughout the bulk of the films after water immersion. The molecular weight affected HPC leaching, pore morphology and film permeability; increasing the molecular weight resulted in decreasing permeability. A model to distinguish the major factors contributing to diffusion retardation in porous films showed that the trend in permeability was determined predominantly by factors associated with the geometry and arrangement of pores, independent of the diffusing species. The film with the highest molecular weight did, however, show an additional contribution from pore wall/permeant interactions. In addition, rapid drying and increasing molecular weight resulted in smaller pores, which suggest that phase separation kinetics affects the final microstructure of EC/HPC films. Thus, the molecular weight influences the microstructural features of pores, which are crucial for mass transport in EC/HPC films. © 2012 Elsevier B.V. All rights reserved.

    Extensional flow, viscoelasticity and baking performance of gluten-free zein-starch doughs supplemented with hydrocolloids2011Inngår i: Food Hydrocolloids, ISSN 0268-005X, E-ISSN 1873-7137, Vol. 25, nr 6, s. 1587-1595Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Viscoelastic doughs of zein and starch were prepared at 40 °C, above the glass transition temperature of zein. The effects of hydrocolloid supplementation with hydroxypropyl methylcellulose (HPMC) or oat bran with a high content of ?-glucan (28%) were investigated by dynamic measurements in shear, confocal laser scanning microscopy (CLSM) and Hyperbolic Contraction Flow. Zein-starch dough without hydrocolloids exhibited rapid age-related stiffening, believed to be caused by cross-links between peptide chains. A prolonged softness was attributed to doughs containing hydrocolloids, with the oat bran exhibiting the most pronounced reduction in age-related stiffening. Moreover, CLSM-images of dough microstructure revealed that a finer fibre network may be formed by increased shearing through an addition of viscosity-increasing hydrocolloids, a reduction in water content in the dough or the use of appropriate mixing equipment. The Hyperbolic Contraction Flow measurements showed that doughs containing hydrocolloids had high extensional viscosities and strain hardening, suggesting appropriate rheological properties for bread making. Zein-starch dough without hydrocolloids showed poor bread making performance while hydrocolloid additions significantly improved bread volume and height. Although the hydrocolloid supplemented doughs had similar extensional rheological properties and microstructures, a fine crumb structure was attributed only to bread containing HPMC, marking the importance of surface active components in the liquid-gas interface of dough bubble walls. Zein could not mimic the properties of gluten on its own, but hydrocolloids did positively affect the structural and rheological properties of zein, which yielded dough similar to wheat dough and bread with increased volume. © 2011 Elsevier Ltd.

    Forward operators are subjected to both physical and mental workload in their work and a way to reduce mental workload and increase productivity is to automating the crane movement. To enable study the impact of automation you need methods to estimate the forwarder operators mental workload in conventional crane work and with semi automation. This study evaluated the psychophysiological parameters; trapezius muscle activity, heart rate, heart rate variability, respiratory rate, skin conductance and finger temperature. To ensure the validity and methodology reliability one need to perform more extensive studies. As for future studies this work propose additional studies of forward operator mental workload in the simulator environment regarding heart rate, heart rate variability and respiration.

    Distansskogsägares nöjdhet med Södras tjänsteutbud och kvalité på tjänster2015Independent thesis Basic level (degree of Bachelor), 180 hpOppgave
    Abstract [en]

    The development of technology and the mechanization in the Swedish forestry has during the last 60 years resulted in depopulation of the country side and due to that the amount of distance forest owners has increased. Therefore the forest companies need to make some adjustments in order to keep the distance forest owners as customers and to attract new ones. The purpose of this essay was to examine and analyze the distance forest owners satisfaction with Södras service offering and quality of service and further develop some proposals for action. A web-based survey was sent out to 634 distance forests owners in Stockholm, Sweden, all members of Södra. 269 respondents participated in the survey and of them, 27 did also participate in a follow-up telephone interview.
