Cold feet comprise problems for lots of people. Various methods can be used for determination of the thermal properties of footwear. A method using a thermal foot model allows the study of the insulation under different conditions. The paper describes the combined effect of walking and sweating on thermal insulation. Walking and sweating simulation on the foot model reduced the total insulation up
A special gait-training programme, combining a psychological therapeutic approach with methods in physiotherapy and body awareness, was used to re-educate nine unilateral trans-femoral amputees. All were rehabilitated trauma or tumour amputees with an age of 16-60 years. They had worn prostheses for more than 18 months. The re-education aimed at integrating the prosthesis in normal movements and i
Popular Abstract in Swedish Anhöriga – aspekter på börda, livstillfredsställelse och effekter av stöd. Med en ökande befolkning av äldre och en samtidig minskning av möjligheter till hjälpinsatser inom såväl kommunalt som landstingsstyrd vård och omsorg, kommer många av oss ta hand om äldre familjemedlemmar, släktingar och vänner. Hur kommer detta att påverka oss? Ungefär 20 % av den vuxna befolWith an aging population and a reduction in social services provided by the municipality, a huge majority of us will take care of elderly family members, relatives and friends in need of assistance. How will this affect our lives? Approximately 20% of the adult population in Sweden, mainly middle-aged persons, identify themselves as family caregivers. Many of these caregivers are working and, at
This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. The motivation for this is that with technological development and exploitation of more sensors in tracking systems, OOSMs gain more significance in various applications. The thesis derives
X-ray and neutron reflection studies, the latter in conjunction with contrast variation, have been combined to study the interaction of calf thymus DNA (ctDNA) with monolayers of distearoylphosphatidylcholine (DSPC) in the presence of 20 mM Ca2+ ions, at the air–liquid interface as a function of surface pressure (10, 20, 30 and 40 mN m−1). Analysis of the X-ray and neutron reflection data showed t
Popular Abstract in Swedish De två vanligaste typerna av neurodegenerativ demenssjukdom är Alzheimer’s sjukdom och Lewy body demens. Båda sjukdomarna drabbar framförallt äldre människor och risken att insjukna ökar med stigande ålder. Detta innebär att demenssjukdom kommer att bli vanligare i samhället, eftersom vi blir allt äldre och andelen invånare >65 år blir allt större. Att drabbas av demensBackground: A prognostic marker should provide information about course and outcome of disease, e.g. predict time to a given endpoint or rate of progression due to disease in patients or subgroups of patients. Prognostic markers could be targeted to apply during the entire clinical course or just during distinct stages of the disease. Aim: The aim of this thesis is to identify, review and qualif
Respiratory minute volumes and instantaneous breath flow rates were measured in 8 subjects during treadmill work using (a) a particle filter respirator(Sundstroem SR200) and (b) a control breathing mask (Metamax I, Cortex). Work comprised five consecutive bouts of walking at 5 km/h with an increase in elevation of the treadmill by 5 % every 5 minutes. Minute ventilationincreased in a curvilinear m
This is the first attempt to budget average current annual carbon (C) and associated greenhouse gas (GHG) exchanges and transfers in a subarctic landscape, the Lake Torneträsk catchment in northern Sweden. This is a heterogeneous area consisting of almost 4000 km2 of mixed heath, birch and pine forest, and mires, lakes and alpine ecosystems. The magnitudes of atmospheric exchange of carbon in the
Background: The survival for patients with atrioventricular septal defect has improved markedly over the last decades and, during the same period, the survival of children with Down's syndrome has also increased. The aim of our study was to investigate long-term survival in patients having atrioventricular septal defect with common valvar orifice, but without associated significant congenital hear
Many breeding attempts in birds do not result in any fledged young due to predation on eggs or young. Consequently, the influence of time constraints on reproductive decisions are integrated parts of the reproductive behaviour of birds breeding within short, seasonal climate zones. In this study. I mimicked nest predation by removing blue tit (Parus caeruleus) clutches shortly after completion. Ar
Galanin is probably involved in nociceptive sensory processing in spinal cord. We investigated whether a common injury, peripheral nerve compression, induced up-regulation of galanin (immunocytochemistry) in sensory neurons in rats 6 or 14 days post-injury and compared the response with other nerve injuries. Sciatic nerve compression increased the number of galanin positive sensory neurons as comp
Background New treatment strategies for early rheumatoid arthritis are evolving rapidly. We aimed to compare addition of conventional disease-modifying antirheumatic drugs (sulfasalazine and hydroxychloroquine) with addition of a tumour necrosis factor antagonist (infliximab) to methotrexate in patients with early rheumatoid arthritis. Methods We undertook a randomised trial in 15 rheumatology uni
The climate impact of new cars in Sweden 2009 has been evaluated by the Swedish Transport Administration. Their report takes into account reduction factors to attribute the positive impact of renewable fuels on CO2 emissions. The Swedish Transport Administration recommends the public to buy cars that can run on biofuels. Besides acknowledging prevailing uncertainties for many of the input paramete
INTRODUCTION Stroke is a serious neurological disease which may lead to death and severe disability [1, 2]. There are two major types of stroke: ischemic and hemorrhagic stroke. Both are associated with disruption of blood flow to a part of the brain with rapid depletion of cellular energy and oxygen, resulting in ionic disturbances and eventually neuronal cell death [3]. The pathologic process t
The responses of the benthic marine dinoflagellate Prorocentrum lima to nutrient stress induced by unbalanced N:P ratios were the subject of this study. Batch cultures of P. lima cells were grown under NP sufficient (N as nitrate and ammonium) and deficient conditions, and the cell growth and toxicity were followed for eight weeks. P. lima grew slowly in all nutrient conditions and net growth rate
A series of fully aromatic polymers having only sulfone bridges linking the aromatic rings has been synthesized via polycondensations and studied as proton-exchange membranes. Mixtures of tetrasulfonated 4,4’-bis[(4-chlorophenyl)sulfonyl]-1,1’-biphenyl (BCPSBP), non-sulfonated BCPSBP and 4,4’-thiobisbenzenethiol were copolymerized by nucleophilic aromatic substitution reactions to obtain sulfonate
The single Trp of human cystatin C, Trp-106, is located in the second hairpin loop of the proteinase binding surface. Substitution of this residue by Gly markedly altered the spectroscopic changes accompanying papain binding and reduced the affinity for papain, actinidin, and cathepsins B and H by 300-900-fold. The decrease in affinity indicated that the side chain of Trp-106 contributes a similar
Popular Abstract in Swedish Grönsaker andas och efter skörd innebär det att de börjar brytas ner. Broccoli är en grönsak som bryts ner snabbt på grund av sin höga andningshastighet, även kallad respirationshastighet. För att förlänga hållbarheten förpackas den ofta i plastförpackningar med syfte att förhindra nedbrytningen och sänka andingshastigheten. Plastfilmer har olika genomsläpplighet för gaThe modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package. This thesis has focused on the MAP of broccoli and the effect of the packa
