Microbially induced sedimentary structures (MISS) in siliciclastic shallow-marine strata occur in the lower and middle Cambrian and the Silurian of southern Sweden. These are typically transparent wrinkle structures with a wide range of morphologies. They are exclusively associated with shoreface to lower shoreface environments, characterized by fine-grained sandstone interbedded with mudstone and

We hypothesized that treating distal radius fractures with cast only or closed reduction and cast is associated with high malunion risk and that the risk is higher in patients with low bone mineral density (BMD).

The combustion timing in internal combustion engines affects the fuel consumption, in-cylinder peak pressure, engine noise and emission levels. The combination of an in-cylinder pressure sensor together with a direct injection fuel system lends itself well for cycle-to-cycle control of the combustion timing. This paper presents a method of controlling the combustion timing by the use of a cycle-t

In this study, nickel pattern electrodes were electrochemically investigated in a three-electrode setup, operating both with H-2/H2O and CO/CO2 atmospheres. Heating introduced structural differences in the nickel layer among the pattern electrodes, which appear to affect the electrode performance. Both dense and porous nickel pattern electrodes were formed by heating. Holes appeared in the nickel

Objective Visual expertise relies on perceptive as well as cognitive processes. At present, knowledge of these processes when diagnosing clinical cases mainly stems from studies with still pictures. Patient video cases constitute a dynamic and authentic, diagnostic challenge that may simulate seeing and diagnosing a patient in person. This study investigates visual attention and the concomitant co

Introduction: Collagen-induced arthritis (CIA) is a mouse model for rheumatoid arthritis (RA) and is induced after immunization with type II collagen (CII). CIA, like RA, is an autoimmune disease leading to destruction of cartilage and joints, and both the priming and inflammatory phases have been suggested to be dependent on proteases. In particular, the cysteine proteases have been proposed to b

Recent data suggest that platelets not only control thrombosis and hemostasis but may also regulate inflammatory processes such as acute pancreatitis. However, the specific role of platelet-derived mediators in the pathophysiology of acute pancreatitis is not known. Herein, we examined the role of CD40 ligand (CD40L, CD154) in different models of acute pancreatitis. Acute pancreatitis was induced

A palliative care approach aims to integrate psychosocial and existential as well as relationship aspects in the care and is an approach that can be used in residential care. Nurse assistants are the ones who are closest to the residents but have limited prerequisites for working in accordance with the palliative care approach. We aimed to investigate the effects on nurse assistants' experiences o

Objectives: Genome-wide association (GWA) studies still rely on the common-disease common-variant hypothesis since the assumption is associated with increased power. In GWA studies, polymorphisms are genotyped and their association with disease is investigated. Most of the identified associations are indirect and reflect a shared inheritance of the genotyped markers and genetically linked causal v

Measuring intima-media thickness (IMT) in the common carotid artery (CCA) is a valuable resource for the evaluation of subclinical atherosclerosis. The main objective of this study was to explore whether a B-mode ultrasound technique, Philips ATL, and an M-mode ultrasound technique, Wall Track System (WTS), show interchangeable results when measured in CCA and the abdominal aorta (AA). A total of

To address immunocapture of proteins in large cohorts of clinical samples high throughput sample processing is required. Here a method using the proteomic sample platform, ISET (integrated selective enrichment target) that integrates highly specific immunoaffinity capture of protein biomarker, digestion and sample cleanup with a direct interface to mass spectrometry is presented. The robustness of

This review provides an update on the importance of the peripheral 'small' airways in asthma. As the small airways account for less than 10% of total airway resistance, thus having little impact on standard lung function measures such as forced expiratory volume and peak flow, they have been referred to as the 'silent zone'.

Introduction Oesophageal stricture is a frequent complication following repair of oesophageal atresia (EA). The aim of this study was to conduct a pre- and postintervention study and analyze the incidence of stricture formation and need for balloon dilatation after introducing prophylactic proton pump inhibitor (PPI) treatment.Children and Design All children operated for EA during 2001 to 2009 (n

Late Svecofennian granite is frequent in the Bothnian Basin, especially in zones of rapidly changing metamorphic grade but also in areas, where the metamorphic grade is elevated. The granite is essentially undeformed, but weakly foliated or lineated rocks are common; more rarely are rocks strongly foliated. X-ray fluorescence was used for major-element and ICP-MS for trace-element analyses. The ch

We measure elastomechanical spectra for a family of thin shells. We show that these spectra can be described by a "semiclassical'' trace formula comprising periodic orbits on geodesics, with the periods of these orbits consistent with those extracted from experiment. The influence of periodic orbits on spectra in the case of two-dimensional curved geometries is thereby demonstrated, where the para

This article engages with the current debate in childhood research on children’s voices and representation in the research process. In this discussion, the frequent use of drawing techniques in childhood research is often highlighted as especially problematic. While agreeing that there is a need to critically examine the concept of ‘children’s voices’ and the production of ‘voices’ in research, th

urinary incontinence (UI) is a common symptom among older people, with a higher prevalence among frail older persons living in nursing homes. Despite consequences such as reduced health and quality of life, many older people do not seek help for their symptoms, resulting in missed opportunity for treatment.

A series of spinel type Fe-V-O phases were prepared with V/Fe atomic ratios ranging from 0 to 1 and were used for methanol oxidation to formaldehyde. X-ray powder diffraction shows that the basic spinel-type structure is retained after use of the samples in methanol oxidation. Compared with the freshly prepared samples, in and ex situ analyses of the samples with XANES show that both V and Fe are

The aim of this study was to compare single-and twin-shaft oxy-fuel gas turbines in a semiclosed oxy-fuel combustion combined cycle (SCOC-CC). This paper discussed the turbomachinery preliminary mean-line design of oxy-fuel compressor and turbine. The conceptual turbine design was performed using the axial through-flow code LUAX-T, developed at Lund University. A tool for conceptual design of axia

In this work the pre- to main chamber ignition process is studied in a Wärtsilä 34SG spark-ignited lean burn four-stroke large bore optical engine (bore 340 mm) operating on natural gas. Unburnt and burnt gas regions in planar cross-sections of the combustion chamber are identified by means of planar laser induced fluorescence (PLIF) from acetone seeded to the fuel. The emerging jets from the pre-
