The purpose of this study was to develop techniques to quantify the propagation pattern of the electrical activation during atrial fibrillation (AF) along a one-dimensional catheter. Taking intra-atrial signal organization aspects into account, the atrial activations are detected and combined into wavefronts. Parameters describing wavefront consistency and activation order along the catheter are d

Nanoclusters containing metallic lead and lead oxide have been produced by self-assembly out of a primary mixture of lead atoms and oxygen in a reactive sputtering-based cluster source. Comparison of the valence and core-level responses in the photoelectron spectra shows that clusters have a core-shell structure with a lead-oxide core coated by an outer shell of metallic lead. This core-shell orde

Contraceptive drugs are nowadays found in aquatic environments around the globe. Particularly, 17 alpha-ethinylestradiol (EE2) may act even at low concentrations, such as those recorded in natural ecosystems. We evaluated the physiological effects of EE2 on cyclopoids and calanoids, common copepods in both marine and freshwater communities. We used three EE2 concentrations and assessed its impact

Popular Abstract in Swedish Varför lade människor ner stenar, ben och redskap i vatten och våtmarker under förhistorisk tid? Och hur kan arkeologin skapa förståelse för denna typ av lämningar? Vanligen tolkas de nedlagda föremålen som offer, men det är ett begrepp som är förknippat med en rad problem. Bland annat riskerar användningen av offerbegreppet att dölja olikheter och nyanser i människornaThis thesis deals with questions concerning theoretical perspectives and archaeological interpretation. It is also a thesis about prehistoric wetland depositions, as they illustrate the discussion. The starting point of the study is the use of the concept of sacrifice (or offering) in Scandinavian archaeology. There are several assumptions, both explicit and implicit, that are considered problemat

3,4-Dihydroxyphenyl-l-alanine (l-DOPA)-induced dyskinesia often develops as a side effect of chronic l-DOPA therapy. This study was undertaken to investigate dopamine (DA) release upon l-DOPA treatment. Chronoamperometric measurements were performed in unilaterally DA-depleted rats, chronically treated with l-DOPA, resulting in dyskinetic and non-dyskinetic animals. Normal and lesioned l-DOPA naiv

Background: Derivatized celluloses, such as methylcellulose (MC) and hydroxypropyl methylcellulose (HPMC), are of pharmaceutical importance and extensively employed in tablet matrices. Each batch of derivatized cellulose is thoroughly characterized before utilized in tablet formulations as batch-to-batch differences can affect drug release. The substitution pattern of the derivatized cellulose pol

The health impact of dietary replacement of carbohydrates with protein for patients with type 2 diabetes is still debated. This study aimed to investigate the association between dietary substitution of carbohydrates with (animal and plant) protein and 5-year weight change, and all-cause and cardiovascular (CVD) mortality risk in patients with type 2 diabetes.

Cholesterol lowering statins have been demonstrated to exert anti-tumoral effects on breast cancer by decreasing proliferation as measured by Ki67. The biological mechanisms behind the anti-proliferative effects remain elusive. The aim of this study was to investigate potential statin-induced effects on the central cell cycle regulators cyclin D1 and p27.

Purpose - This paper aims to empirically explore demand-related information sharing in the extended supply chain. Design/methodology/approach - Through a single, embedded case design, a range of methods are used to collect data from companies representing three different supply chain tiers, including focal company, first-tier suppliers and first-tier customers. The collected data are analysed thro

Popular Abstract in Swedish Cerebral pares (CP) är den vanligaste orsaken till motorisk funktionsnedsättning hos barn och ungdomar med en prevalens på 2-3/1000. CP innebär en livslång funktionsnedsättning och den förväntade överlevnaden är nästan densamma som för befolkningen i stort. CP karaktäriseras av svårigheter med rörelser och postural förmåga och symtomen varierar från knappt märkbara tillCerebral palsy (CP) is the most common cause of motor disability in children and adolescents with a prevalence of 2-3/1000. CP is characterized by disorders of posture and movement with impairments ranging from mild to severe. The ability to control posture is an important prerequisite for all voluntary movements. A sustained asymmetric posture predisposes to progressive deformities in people with

Popular Abstract in Swedish Blodförgiftning är en spridd och svår infektion och har en hög dödlighet. Skador på blodkärlen är en viktig del i sjukdomsutvecklingen. Glykosaminoglykaner (GAG) är negativt laddade kolhydrater som bland annat förekommer på blodkärlens insida och här utgör gränsskiktet mot blodbanan. På denna plats är GAG betydelsefullt för blodkärlens blodproppshämmande effekt, för traThe endothelial glycocalyx is the carbohydrate rich inner layer of the blood vessels. Important components of the glycocalyx are the proteoglycans with their attached glycosaminoglycans. At this location these molecules contribute to the adhesion and transport of leucocytes to inflamed tissue, the anticoagulation as well as the transport of fluid across the vessel wall. All these functions are dis

Submerged breakwaters (SBWs) are becoming a popular option for coastal protection, mainly due to their low aesthetic impact on the natural environment. However, SBWs have rarely been employed for coastal protection in the past and therefore, their efficacy remains largely unknown. The main objective of the present study was to investigate the structural and environmental conditions that govern the

This thesis focuses on cognitive impairment in Out-of-Hospital Cardiac Arrest (OHCA) survivors with the main aim to evaluate possible effects by targeted temperature management. Secondary aims are to describe the prevalence of cognitive impairment in a large group of OHCA-survivors, the related symptoms of psychological distress and the actual effect of cognitive impairment for the patient’s abili

This paper presents a novel control architecture for hybrid stiff and compliant control for minimally invasive surgery which satisfies the constraints of zero lateral velocity at the entry point for serial manipulators. For minimally invasive surgery it is required that there is no sideways motion at the point where the robots enter the abdomen. This is necessary to avoid any damage to the patient

Although many studies have investigated the role of customer orientation and learning orientation on a firm's performance in small, medium, and large enterprises, the literature provides little empirical evidence about the role of customer orientation and learning orientation within the hotel industry. This current work investigates the influence of these variables on new service development and t

Soft tissue sarcomas (STS) are challenging as they represent a morphologically and genetically heterogeneous groups of tumors. A multitude of genetic changes, often in the form of fusion genes, were recognized during the 1980's and now constitute a diagnostic lexicon in several STS subtypes, whereas many of the more common subtypes are genetically complex without distinct alterations. Refined STS
