We investigated motor-equivalent stabilization of task-related variables (TRV) at times of heel strike in eight healthy young men (23-30 years) who walked on a motorized treadmill at self-selected and prescribed speeds within the normal walking speed range. The TRV consisted of step parameters (step length and width) and the center of mass (CoM) position relative to the support (back and front fee

The FRR (Friendly Rest Room) project creates and evaluates prototypes of a more user friendly intelligent toilet for old persons and for persons with disabilities. Additionally, applicable knowledge regarding needs and wishes of old and/or disabled persons and their care persons are documented. In this paper the user driven research approach, ethical aspects and the iterative user centred design p

The chromosome number of the polyploid species Glechoma hederacea was found to be 2n = 36 in a sample of 93 ramets derived from 27 sites in N and C Europe. Variation in 10 enzymes was surveyed in material from S Sweden and S Czech Republic. The genetic control of variation was investigated using segregating progeny from crosses and self-fertilized heterozygous plants. The generic analysis comprise

The 35 by 50 km large, Mesoarchaean Finnefjeld domain near Maniitsoq in the North Atlantic craton of southern West Greenland constitutes the central part of the previously proposed, deeply eroded Maniitsoq impact structure with an age of 3.0 Ga. The Finnefjeld domain is an exceedingly homogeneous, quartzo-feldspathic rock mass which superficially appears to be a late-orogenic, deep-crustal, intrus

The objective of this study was to create a superhydrophobic surface using polymers that are non-fluorinated and applying them to a surface via rapid expansion of a supercritical solution (RESS). Solubility studies of poly(epsilon-caprolactone) (PCL) and a statistical copolymer of vinyl acetate and vinyl pivalate (P(VAc-VPi))in supercritical carbon dioxide (scCO(2)) were carried out using an extra

Popular Abstract in Swedish Dieselmotorn, uppkallad efter sin uppfinnare Rudolf Diesel, patenterades 1892 och har sedan dess bidragit väsentligt till utvecklingen av samhället. Den viktigaste användningen är som kraftkälla i fordon och detta användningsområde ökar fortfarande. Andelen dieselmotorer i nyregistrerade personbilar i Västeuropa har nyligen passerat 50 %. För kommersiella fordon som lasThis project deals with questions related to generic diesel combustion research and optically accessible engines are used to study the combustion process. Images of the combustion are analyzed together with in-cylinder pressure and exhaust gas emission measurements. The results can be divided into two main categories: one about evaluations of optically accessible engines and one about studies of e

Vardagliga ting, så som detta papper, är sammanställt av vanlig materia. Det vi ser med våra ögon och genom teleskop när vi tittar upp mot stjärnorna är också sammanställt utav vanlig materia. Det visar sig att denna materia endast fyller vårt kända universum till 5 %. Resten kallas för Mörk Materia och Mörk Energi, där den föregående fyller universum med 27 % och den snarare till 68 %. Mörk MaterIn this thesis, I present a case where Dark Matter subhalos would annihilate at some stage in their lifetime. The implication of this scenario could potentially aid the Missing Satellites and the Cusp-Core density profile problem. The Dark Matter particles’ annihilation process and effective “friction” lead to an energy and momentum loss into radiation and hence to the destabilization of the Dark

Gone are the days when women were exclusively confined to care work in the private sphere and men dominated in the public sphere. Still, the increase in the number of women in gainful employment has not engendered a more equitable division of family responsibilities inside the family unit. In fact, the birth of a child often entails in itself a ‘re-traditionalisation’ of working and family pattern

Background: Scotland possesses the worst mortality outcomes and slowest improvement in life expectancy of Western Europe. Within Scotland, stark inequalities exist in both morbidity and mortality. There remains paucity in assessment of subnational variation in disease burden. Aim: This thesis explored geographical inequalities in burden of disease (BoD) across 32 Scottish authorities. Secondary an

The aim of this Master's thesis is to construct an algorithm that nds the optimal credit limit for an individual credit card holder. It should be optimal in the sense that the algorithm suggests the lowest credit limit required for reaching the business goal of generating "X SEK within d days after limit raise" for the issuer of the credit card. This is achieved in three stages. Firs

Objective: The aim of this study was to analyse the occurrence of neonatal early onset group B streptococcal (EOGBS) disease relative to maternal body mass index (BMI). Method: A cohort of Swedish parturients with an early pregnancy BMI registered was investigated. Data were retrieved from population-based registers during 1997-2001, (n = 344 127, elective caesarean section excluded). Medical reco

We present a high-resolution and independently dated multiproxy lake sediment record from the paleolake at Les Echets in southeastern France that displays synchronous changes in independent limnic and terrestrial ecosystem proxies, in concert with millennial-scale climate oscillations during the last glacial period. Distinct lake-level fluctuations, low lake organic productivity, and open, treeles

The possibility to study variations in the oxygen isotopic ratio with photon tagged nuclear reaction analysis (pNRA) is evaluated in the current work. The experiment described in the article was performed at Lund Ion Beam Analysis Facility (LIBAF) with a 2 MeV deuteron beam. Isotopic fractionation of light elements such as carbon, oxygen and nitrogen is the basis of many analytical tools in hydrol

A new setup for photon tagged nuclear reaction analysis pNRA is being developed at Lund's ion beam analysis facility LIBAF. Particle induced gamma ray emission PIGE and nuclear reaction analysis NRA are two methods that have been extensively used for light isotope measurement in ion beam analysis IBA. There is an abundance of nuclear reactions between light elements and MeV protons, deuterons and

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

Människor strävar ofta efter att uppvisa en positiv fasad, både på sociala medier och i verkliga livet. Att undertrycka sina känslor och tvinga sig själv att vara positiv är något som i populärkulturen benämns som “toxic positivity”. Syftet med studien var att undersöka sambandet mellan ett undertryckande av känslor (suppression), enligt Gross (2002) emotionsregleringsmodell, och välmående. Vi strPeople often strive to exhibit a positive facade, both on social media as well as in real life. To suppress one's feelings and force oneself to be positive is something which in popular culture is referred to as “toxic positivity”. The aim of this study was to examine the relationship between suppression of feelings, or simply “suppression” according to the emotional regulation model formulate

According to efficient market theory, all publicly available information is reflected in asset prices. In its semi-strong form, fundamental analysis cannot be used as a method to generate an abnormal return. Implying that abnormal return can only be achieved by incurring a higher level of risk. Joel Greenblatt (2006) shows that by applying simple fundamental analysis and ranking companies based on

Valencia has faced persistent flooding challenges, intensified by climate change and extreme weather events. The artificial Turia River channel, constructed after the catastrophic 1957 flood, has become increasingly inadequate. In 2024, intense rainfall overwhelmed the system again, especially in the La Torre district, exposing critical gaps in the city’s flood resilience. This project focuses on
