BACKGROUND: Postural instability is considered a late complication of Parkinson’sdisease (PD). However, growing evidence shows that balance and gait problems mayoccur early in the disease.OBJECTIVE: To describe balance, gait, and falls/near falls in persons with newlydiagnosed, untreated PD (“de novo”), and to compare this with persons with mildmoderatePD (Later PD). In addition, we evaluated diffBackgroundPostural instability is considered a late complication of Parkinson’s disease (PD).

Geophysical investigations can provide important information for design and risk assessment provided that the optimal method and interpretation approach is adopted.This work presents results from seismic refraction surveys carried out along a planne

In terms of its total population, Sweden is one of the countries with the highest proportion of immigrants in the EU. Several factors are critical in integrating immigrants, especially their economic security in a new country. This thesis examines the relationship between law enforcement and economic security for over- indebted immigrants. The primary purpose of this research is to explore the rel

Purpose: The optimal ventilatory settings in patients after cardiac arrest and their association with outcome remain unclear. The aim of this study was to describe the ventilatory settings applied in the first 72 h of mechanical ventilation in patients after out-of-hospital cardiac arrest and their association with 6-month outcomes. Methods: Preplanned sub-analysis of the Target Temperature Manage

Experimental data on pulmonary regurgitation has linked right ventricular longitudinal function to left ventricular filling pressure in animals with induced and treated pulmonary regurgitation but this relationship has not been investigated in patients with repaired Tetralogy of Fallot (rToF). The aim of this study was to determine if right ventricular longitudinal function assessed using cardiova

Cobalt (Co) nanoparticles (NPs) may be diffusely dispersed into natural ecosystems from various anthropogenic sources such as traffic settings and eventually end up in aquatic systems. As environmentally dispersed Co NPs may be transferred through an aquatic food web, this study investigated this transfer from algae (Scendesmus sp.) to zooplankton (Daphnia magna) to fish (Crucian carp, Carassius cCobalt (Co) nanoparticles (NPs) may be diffusely dispersed into natural ecosystems from various anthropogenic sources such as traffic settings and eventually end up in aquatic systems.

Vi spenderar en tredjedel av våra liv sovandes och sömn är en avgörande faktor för god hälsa och välbefinnande. Men det är även viktigt att erkänna sömnens komplexitet, eftersom det är flera faktorer som kan påverka sömnen. Både biologiska, kontextuella och psykosociala faktorer har inverkan på ungdomarnas sömn. Otillräcklig sömn, sömnproblem och symptom på insomni är vanligt hos ungdomar. SömnlösInsufficient sleep, sleep problems and insomnia are common in adolescents, and insomnia and insufficient sleep are public health concerns that can impact adolescents’ mental and physical health. There are several different treatments for sleep problems and insomnia, and there is a great focus on the problem when it has already arisen. However, since this is a public health problem, it is important

Vi lever i en tid av snabb vetenskaplig och teknologisk utveckling. För 100 år sedan hade ingen kunnat drömma om de saker som helt har förändrat vår var- dag och hur vi uppfattar omvärlden; datorer, mobiltelefoner, Internet, rymdfart, våra upptäckter om universums barndom och avlägsna galaxer samt vår insyn i kvantfenomenens mikroskopiska värld. Idag står vi på tröskeln till en era formad av nanotWe live in a time of rapid scientific and technological advancement. People liv- ing 100 years ago could never dream of inventions like those having completely changed our way of life, and our perception of the world; computers, mobile phones, the Internet, space travel, unraveling the mysteries of the early universe and distant galaxies, and our insight into the microscopic world of quantum phe-

Ett antal superkontinenter har existerat under jordens 4.6 Ga ( miljarder år gamla ) historia. Utav dessa är superkontinenten Pangea, som betyder ”allt land”, den senaste och mest väldefinierade. Bildning och uppsprickning av superkontinenter drivs av plattektoniska processer som i sin tur beror på strömningar ( konvektion ) i jordens mantel. Förutom dessa processer så anses numera mantelplymer haEarth history is punctuated by a series of events of supercontinent amalgamation and break-up. Fragments of old continents display rifted margins and orogenic sutures that testify their involvement in supercontinent cycles. Periods of break-up are associated with widespread magmatism due to extensional thinning and rifting of the lithosphere and in some instances the arrival of mantle plumes. Mant

Popular Abstract in Swedish Fosterövervakning under förlossningen är standard inom förlossningsvården. Målet är att identifiera avvikande händelser och då speciellt syrebrist hos fostret. Sedan början på sjuttiotalet har vågformsanalys av foster EKG studerats ur fysiologisk, klinisk och signal synpunkt. Vågformen hos ett EKG innehåller mer information än bara R-R intervallet i ett EKG dvs konventiWaveform analysis of the fetal electrocardiogram has been studied since the early seventies from both physiological, signal processing and clinical aspects. It has been found to contain more useful information than the mere detection of RR-intervals (fetal heart rate), e.g., the ST-segment giving evidence of the ability of fetal myocardium to respond to the stress of labor. In the Swedish RCT, STA

Popular Abstract in Swedish Global uppvärmning, säkerhetspolitik och framtida minskad tillgång på fossila bränslen har de senaste åren skyndat på sökandet efter nya, förnyelse-bara drivmedel. Användningen av bioetanol har ökat avsevärt och är idag ett av de vanligaste biobränslena i världen. Idag framställs bioetanol vanligen genom jäsning av socker från socker-rör eller från stärkelse (från tillFuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. However, ethanol production from xylose is slow and often incomplete.

Vetenskapligt skrivande är ett viktigt moment i studentens grundutbildning. Skrivandet kräver att studenten ska ange källor på ett korrekt sätt i enlighet med en viss stil. Av erfarenhet konstateras att processen att hantera olika stilar kräver tid. Kritiskt tänkande är en grundläggande förutsättning inom vetenskapligt arbete och kräver i sig inte detaljkunskap kring olika stilars struktur. Dagens

Popular Abstract in Swedish Trä är ett konstruktionsmaterial med många positiva egenskaper, både avseende mekaniska och tekniska egenskaper och avseende det som ibland kallas mjuka egenskaper. Trä har generellt hög styrka i förhållande till sin vikt, det är ett naturligt förnybart material och det anses av många vara estetiskt tilltalande. Jämfört med andra vanliga konstruktionsmaterial som stål oThis thesis concerns experimental and theoretical work regarding perpendicular to grain fracture in wooden structural elements. The experimental part concerns strength tests of glulam beams with a hole. The theoretical parts concern development of two models for strength and fracture analysis, both based on fracture mechanics approaches, and their application to analysis of beams with a hole and d

The purpose of this work was to study how the pixel size of digital detectors can affect shape determination of microcalcifications in mammography. Screen-film mammograms containing microcalcifications clinically proven to be indicative of malignancy were digitised at 100 lines/mm using a high-resolution Tango drum scanner. Forty microcalcifications were selected to cover an appropriate range of s

De första mikrosekunderna efter Big Bang (den stora smällen) tros det ha bildats något som kallas kvark-gluonplasma. Kvark-gluonplasma består av kvarkar och gluoner, som är så kallade elementärpartiklar. Elementärpartiklar är de minsta kända beståndsdelarna. Kvarkarna bygger upp större partiklar som kallas hadroner, exempel på hadroner är protonen och neutronen som atomkärnan består av. Det som håIn high-energy heavy-ion collisions, a state of matter called quark-gluon plasma (QGP) can be created. The production of particles from the QGP can be described by different models, one of these is the blast-wave model. The blast-wave model describes the production of particles from the QGP, not from jets. The model was fitted to the existing transverse momentum spectra (pT) for pions, kaons and p
