Background: The aim of this study was to investigate graft preservation, major bleeding, and reinfection rate using negative pressure wound therapy (NPWT) for perivascular surgical site infections (SSIs) in the groin after vascular surgery and factors associated with failure of treatment. Methods: Retrospective data were collected during 2004-2015. Failure of wound treatment was defined as a wound
Following experimental and clinical traumatic brain injury (TBI), the local cerebral metabolic rate of glucose (lCMR(Glc)) is commonly estimated using the 2-[(18)F]fluoro-2-deoxy-D-glucose (FDG) method. The adequate estimation of lCMR(Glc) using FDG requires a correction factor, the lumped constant (LC), to convert FDG net uptake into lCMR(Glc). The LC, and thus lCMR(Glc) calculations, require a s
Background: Participation in everyday life and society is generally seen as essential for health-related outcomes and acknowledged to affect older people’s well-being. Aims: To investigate if aspects of performance- and togetherness-related participation influence on mortality among very old single living people in Sweden. Methods: ENABLE-AGE Survey Study data involving single-living participants
The present study numerically investigates the second law analysis of turbulent flow in novel outward helical corrugated tubes by using a Reynolds Stress Model (RSM). A case of a transverse corrugated tube and five cases of helical corrugated tubes with different height-to-diameter ratios and pitch-to-diameter ratios are examined with Reynolds number ranging from 3800 to 43,800 at a constant wall
Livestock production is important for local food security and as a source of income in sub-Saharan Africa. The human population of the region is expected to double by 2050, and at the same time climate change is predicted to negatively affect grazing resources vital to livestock. Therefore, it is essential to model the potential grazing output of sub-Saharan Africa in both present and future clima
This paper examines the linkages between cash-crop income and other dimensions of poverty to interrogate assumptions regarding the relationship between agricultural income and poverty alleviation. The analysis treats poverty as a multi-dimensional and socially disaggregated phenomenon. The paper employs a mixed methods approach to case studies of Ghana and Ethiopia to explore two critical issues.
Different perceptions of the concept of extended producer responsibility and product stewardship (EPR/PS) have tended to lead to prolonged policy disputes and have likely affected the design of EPR/PS policies. We therefore surveyed stakeholders’ perceptions of the concept of EPR/PS, including its aims, application, and rationales, and analyzed 376 responses with regression analysis and cluster an
The high endwall heat transfer in the junction of the hub and vane/blade is very crucial in turbomachinery and is of great concern for increasing the gas turbine inlet temperature but avoiding hot spots. The vortices generated in that region are mainly responsible for the high heat transfer. By controlling these vortices, heat transfer in the junction region can be controlled. In this study, a new
Understanding how environmental variation drives phenotypic diversification within species is a major objective in evolutionary biology. The seaweed fly Coelopa frigida provides an excellent model for the study of genetically driven phenotypes because it carries an α/β inversion polymorphism that affects body size. Coelopa frigida inhabits highly variable beds of decomposing seaweed on the coast i
Standard formulations of smoothed particle hydrodynamics (SPH) are unable to resolve mixing at fluid boundaries. We use an error and stability analysis of the generalized SPH equations of motion to prove that this is due to two distinct problems. The first is a leading order error in the momentum equation. This should decrease with an increasing neighbour number, but does not because numerical ins
The trend in the district heating industry is toward increased privatization and openness to competition, which bring with them other phenomena associated with civil law, such as bankruptcies. Vingåker was one of six Swedish municipalities whose district heating companies went bankrupt in 2004. The bankruptcy caused major disruptions in Vingåker, not least as a result of the unregulated legal fram
Relocating Beijing's manufacturing industry, a key measure in the strategy for decentralizing Beijing's non-capital functions, may inadvertently increase environmental pressures in the receiving cities. This study develops a quantitative method to comprehensively identify the environmental effects caused by regional industrial relocations. First, a set of relocated industries is selected by consid
Popular Abstract in Swedish Biotisk och abiotisk stress hos mikroorganismer och växter.Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. coli, was subjected to directed evolution with NaCl as selective pressure. The resulting clones were teste
The partially premixed combustion (PPC) concept has shown high efficiency with low soot emissions. However, the in-cylinder phenomena are still to be explained and evaluated for further progress in the research. This work studies the start of combustion process during a transition from homogenous charge compression ignition (HCCI) to PPC. The process is visualized using a heavy-duty, non-swirling
Background: One of the most serious complications after pancreaticoduodenectomy (PD) is postoperative pancreatic fistula (POPF). This study investigated the incidence of POPF before and after centralization of pancreatic surgery in Southern Sweden and its impact on outcome and health care costs. Methods: The local registry comprising all pancreatic resections at Skåne University Hospital, Lund, Sw
The voluminous literature on industrial catching-up in Southeast Asian countries has regularly argued that successful catching-up largely depended on a committed state, which orchestrated industry development with a relatively uniform set of policies, including R&D support, subsidies, trade restrictions, and local content requirements. In contrast, recent contributions from the technology life
Objective. To analyze the characteristics of anti-RNA polymerase III antibodies (anti-RNAP3)- positive patients with systemic sclerosis (SSc) in the European League Against Rheumatism Scleroderma Trials and Research group (EUSTAR) registry with a focus on the risk of cancer and the characteristics of malignancies, and the aim to provide guidelines about potential cancer screening in these patients
The large bloom-forming flagellate Gonyostomum semen has been hypothesized to be inedible to naturally occurring zooplankton due to its large cell size and ejection of long slimy threads (trichocysts) induced by physical stimulation. In a grazing experiment using radiolabelled algae and zooplankton collected from lakes with recurring blooms of G. semen and lakes that rarely experience blooms, we f
Many studies have found close relationships between accessibility and various socio-economic indicators. Yet, since accessibility tends to have differentiated effects, both socially and spatially, there is a need for a model which allows for a disaggregated analysis of accessibility. The model should be possible to use in areas where road network data is incomplete. In this paper such an accessibi
Sensing and manipulating living cells using vertical nanowire devices requires a complete understanding of cell behavior on these substrates. Changes in cell function and phenotype are often triggered by events taking place at the plasma membrane, the properties of which are influenced by local curvature. The nanowire topography can therefore be expected to greatly affect the cell membrane, emphas
