Software systems are becoming increasingly ubiquitous and can be found in devices we use every day from mobile phones to cars. As our reliance on software-based systems increases, our tolerance with software that is ill-fitted to our needs decreases. We expect these devices to function whenever and however we need them to. However, developing these (often) large and complex software systems to mee
Multiple myeloma is a malignancy of plasma cells predominantly located in the bone marrow. A number of bone morphogenetic proteins (BMPs) induce apoptosis in myeloma cells in vitro, and with this study we add BMP-9 to the list. BMP-9 has been found in human serum at concentrations that inhibit cancer cell growth in vitro. We here show that the level of BMP-9 in serum was elevated in myeloma patien
Diabetic peripheral polyneuropathy (PN) is a common and serious complication of diabetes. The prevalence of PN is rising with the global burden of type 2 diabetes. The causal mechanisms of PN are not fully understood, but both vascular and metabolic factors play a role. New methods of investigating PN need to be correlated with standard methods in well-defined, population-based cohorts. Objective
The aim of this study was to compare the vacuum assisted wound closure (VAC) system (negative pressure wound therapy; NPWT) and alginate wound dressings in terms of quality of life (QoL), pain resource use and cost in patients with deep peri-vascular groin infection after vascular surgery.
This article sets out to study the ways in which reactions and adaptations to modernity and societal change among non-elite communities in late nineteenth-century Sweden are visible in contemporary attitudes to social deviants and nonconformists. In Swedish provincial cultures, narratives about local characters in the oral tradition played a significant part in regional identity formation in the n
A new method for detecting jerks in safety critical events, based on the characteristics of the braking caused by the driver in time critical situations, has been developed and evaluated in a small pilot test and also applied on a naturalistic driving study. A portable event data recorder, capable of measuring and recording acceleration profiles for a predetermined time period before and after the
The optimal mating system is rarely the same for males and females-whereas males usually benefit from attracting additional females to the territory, this could incur costs for the resident female. Females should therefore prevent prospecting females from settling on the territory. We studied the male and female behavioral and hormonal responses to simulated female territorial intrusions in free-l
This paper deals with steady-state analysis and design of bioreactors consisting of a number of completely stirred tank reactors (CSTRs) in series. The study is confined to one consumed (substrate) and one consuming constituent (biomass). The specific microbial growth rate is assumed to be described by Monod kinetics. The death of biomass is assumed to be negligible. Two optimal design problems fo
The Baltic Sea has experienced three major intervals of bottom water hypoxia following the intrusion of seawater circa 8 kyr ago. These intervals occurred during the Holocene Thermal Maximum (HTM), Medieval Climate Anomaly (MCA), and during recent decades. Here we show that sequestration of both Fe and Mn in Baltic Sea sediments generally increases with water depth, and we attribute this to shelf-
Background: Treatment at stroke units is superior to treatment at other types of wards. The objective of the present study is to determine the effect size of stroke unit care in subgroups of patients with stroke. This information might be useful in a formal priority setting. Methods: All acute strokes reported to the Swedish Stroke Register from 2001 through 2005 were followed until January 2007.
We used a thin-film thermocouple to detect the thermal effect of surface plasmons excited in Au nanohole array structures. We found that the thermal electromotive force of Au film with periodic nanohole structures is three times greater than that of a bare Au film for 785-nm laser excitation at a given power. This effect is caused by the resonant excitation of localized surface plasmons in the nan
Popular Abstract in Swedish Svår alfa-1antitrypsinbrist (AAT-brist), s.k. PiZZ, är ett ärftligt tillstånd som har en hög förekomst i Sverige, cirka 1/1600. Bristen innebär ökad risk för utveckling av kroniskt obstruktiv lungsjukdom (KOL), speciellt hos rökare. Leversjukdom är också relativt vanlig och kan förekomma såväl i barndomen som i hög ålder. Levercirros (skrumplever) och levercancer är öveSevere alpha-1 antitrypsin deficiency (AATD) is a genetic disorder associated with increases risk of developing of chronic obstructive lung disease and liver disease. The Swedish National Registry for individuals with severe AATD was started 1991.Up to October 2008, a total of 1349 individuals were included in the registry. The aims of the studies in this thesis which bases on AATD registry are to
A search for a fermiophobic Higgs boson using diphoton events produced in proton-proton collisions at a centre-of-mass energy of root s = 7 TeV is performed using data corresponding to an integrated luminosity of 4.9 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. A specific benchmark model is considered where all the fermion couplings to the Higgs boson are set to zero and
Background: A delay in surgical nerve repair results in impaired nerve function in humans, but mechanisms behind the weakened nerve regeneration are not known. Activating transcription factor 3 (ATF3) increases the intrinsic growth state of injured neurons early after injury, but the role of long-term changes and their relation to axonal outgrowth after a delayed nerve repair are not well understo
Reklamen blinkar, ljuder, ändrar färg och form. Söta djur och maskotar svischar förbi, tonas ned, dyker plötsligt upp igen. Köp, beställ, registrera dig, klicka här! Ibland skriker den högljutt. Ibland är den helt tyst, knappt synlig, svår att fånga, svår att skilja ut, men uppmuntrar till interaktion och pockar på barns uppmärksamhet. Marknadsförare är allt mer angelägna om att kommunicera med ba
The most typical enhancement for electrokinetic remediation (EKR) involves the neutralization of the alkaline front generated at the cathode by the addition of an acid to the catholyte. Although the use of strong and weak acids can be found in the literature, there is still a clear lack of reliable comparisons between them. This paper presents a comparison of the results obtained for a real lead c
The objective of this exploratory study was to develop signal processing methods for assisting in the diagnosis of arteriovenous fistula stenosis on patients suffering from end-stage renal disease and undergoing haemodialysis treatments. The proposed method is based on the classification of vessels sounds utilizing parameter extraction from wavelets transform coefficients. The coefficients energy
Popular Abstract in Swedish Joniserande strålning används ofta som behandling vid olika tumörsjukdomar i bukhåla och bäckenregion men är ibland förenad med biverkningar. Dessa kan uppkomma tidigt/akut, dvs i direkt anslutning till genomförd behandling eller sent, efter månaderår. Besvären kan vara av mycket varierande och ofta lindrig övergående karaktär såsom buksmärtor, diarré och blödningar fråGastrointestinal tract damage is an insidious feature in patients undergoing radiotherapy. Microvascular inflammation, including leukocyte and platelet recruitment as well as epithelial barrier dysfunction, are considered to constitute key components in the pathophysiology of radiation-induced enteropathy. The aim of this thesis was to investigate the basic mechanisms behind leukocyte-platelet-end
