Non-aqueous amine systems have been suggested as energy-efficient alternatives to conventional aqueous amine systems in post-combustion carbon capture, as low regeneration temperatures can be achieved. The solubility of CO2 and heat of absorption in non-aqueous systems were studied using the sterically hindered amine 2-amino-2-methyl-1-propnaol (AMP) in the organic solvent dimethyl sulfoxide (DMSO

This paper aims to provide a novel enhanced heat transfer method for the internal tip surface of a U bend channel of relevance for a gas turbine rotor blade. The DWVGs (delta-winglet vortex generators) pair is arranged at multiple locations on the tip surface. Two types of vortex generators are studied, including common-flow-up and common-flow-down configurations. The inlet channel Reynolds number

CVD and cancer are the two leading causes of death worldwide. Improvement in cancer early detection and treatment has resulted in an increased number of cancer survivors. However, many of the survivors tend to develop CVD often leading to their demise. Conversely, people with pre-existing CVD conditions, especially the elderly, have increased chances of developing cancer and dying from the same. T

We report the formation of silicide by annealing of a SiOx surface, with low coverage of Eu doped Gd2O3 nanoparticles. The annealing temperature required for removal of native oxide from the Si substrate decreases with close to 200 °C in presence of the nanoparticles. X-ray photoemission electron microscopy, low-energy electron microscopy and mirror electron microscopy are used to monitor the sili

In this paper, we propose a blind channel deconvolution method based on a sparse reconstruction framework exploiting a wideband dictionary under the (relatively weak) assumption that the transmitted signal may be assumed to be well modelled as a sum of sinusoids. Using a Toeplitz structured formulation of the received signal, we form an iterative blind deconvolution scheme, alternatively estimatin

In this work, we demonstrate the application of terahertz-optical Hall effect (THz-OHE) to determine directionally dependent free charge carrier properties of ambient-doped monolayer and quasi-free-standing-bilayer epitaxial graphene on 4H–SiC(0001). Directionally independent free hole mobility parameters are found for the monolayer graphene. In contrast, anisotropic hole mobility parameters with

Cost- and resource-efficient growth is necessary for many applications of semiconductor nanowires. We here present the design, operational details and theory behind Aerotaxy, a scalable alternative technology for producing quality crystalline nanowires at a remarkably high growth rate and throughput. Using size-controlled Au seed particles and organometallic precursors, Aerotaxy can produce nanowi

The nitric oxide (NO) formation in methane (CH4) flames has been widely investigated, with quite a few kinetic mechanisms available in the literature. However, studies have shown that there are often discrepancies between the simulations using various mechanisms and the experimental results. To elucidate reactions leading to these discrepancies, experiments were designed to measure the NO formatio

Children's plasma metabolome, especially lipidome reflects gene regulation and dietary exposures, heralding the development of islet autoantibodies (IA) and type 1 diabetes (T1D). The TEDDY study enrolled 8676 newborns by screening HLA-DR-DQ genotypes at six clinical centers in four countries; profiled metabolome and measured concentrations of ascorbic acid, 25-hydroxyvitamin D (25(OH)D), erythroc

Deploying solar reflective materials on urban surfaces is known as an effective heat mitigation strategy. Several studies have shown their cooling impacts; however, most of them have focused on rooftops rather than facades. The novelty of this paper is related to exploring the impact of each façade orientation on the corresponding microclimate and energy balance. High albedo materials were impleme

The sharing economy is having a transformative impact on our cities, and many municipalities are facing a challenge – how to systematically engage with the sharing economy to both mitigate its negative and enhance its positive impacts. Academic understanding of municipal governance mechanisms of the sharing economy remains poor. To address this gap, we develop a comprehensive analytical framework

Vi vill med den här artikeln peka på att Sveriges städer har flera utmaningar kring styrning och hantering av vatten, samt föreslår sju principer för lösningar. Klimatförändringarna och den urbana tillväxten gör att åtgärder behövs nu för att hantera både vattenbrist och översvämning på ett integrerat sätt. Här fokuserar vi på kommunnivå och urbana områden, där vi argumenterar för att det behövs eWe argue in this paper that Swedish urban areas have several urgent challenges when it comes to water governance and we propose seven principles for addressing them. Climate change and urban growth call for swift action to manage both water scarcity and flooding in an integrated way. This paper focuses on the municipal level for which we argue that there is a need for a more systematic approach. T

This article studies the implementation of the global norm of women’s inclusion in the Malian peace negotiations. It constructs a theoretical framework for analyzing practices of resistance, which object to the validity of the norm, and practices of refinement, which engage with the application of the norm. Based on interviews with women who attended the Malian peace negotiations it finds that wom

OBJECTIVE: To describe a novel strategy, Multilevel Analysis of Individual Heterogeneity and Discriminatory Accuracy (MAIHDA) to evaluate hospital performance, by analysing differences in 30-day mortality after a first-ever acute myocardial infarction (AMI) in Sweden.DESIGN: Cross-classified study.SETTING: 68 Swedish hospitals.PARTICIPANTS: 43 247 patients admitted between 2007 and 2009, with a fi

Background Mammography screening reduces breast cancer mortality, but a proportion of breast cancers are missed and are detected at later stages or develop during between-screening intervals. Purpose To develop a risk model based on negative mammograms that identifies women likely to be diagnosed with breast cancer before or at the next screening examination. Materials and Methods This study was b

Linguistic relativity is a notion that has been met with both praise and scorn. We argue that there is correlation between theorists’ general conceptions of the nature of language, and their stance toward linguistic relativity. Starting with the proponents of the thesis, we distinguish between the relativists of the early days (Boas, Whorf) and modern neo-Whofians (Levinson, Slobin), showing that

Abstract: Thermoregulating microcapsules (MC) with flame-retardant properties were used to produce polyurethane (PU) foams. Thermogravimetric analyses of the microcapsules performed under atmospheric air and nitrogen confirmed that the hexa(methacryloylethylenedioxy) cyclotriphosphazene (PNC-HEMA) monomer raised the amount of residue after exposure to high temperature, proving the formation of a t

Hip fractures are a major health problem with high socio-economic costs. Subject-specific finite element (FE) models have been suggested to improve the fracture risk assessment, as compared to clinical tools based on areal bone mineral density, by adding an estimate of bone strength. Typically, such FE models are limited to estimate bone strength and possibly the fracture onset, but do not model t

This study follows groups in Sweden that are involved in a political struggle to change norms regarding sexuality and disability. The groups are mostly connected to the disability movement or the movement of sexual politics. The following questions have guided the research process: How do the groups describe their activities? What strategies do they use? What relations can be identified between th

In this paper we analyze how the location of firms influences their innovation outcomes, particularly the complexity of the outcomes. Using three waves of the Community Innovation Survey in Sweden for a balanced panel of firms from 2006 to 2012, we identified a range of innovation outcome categories, i.e. simple and complex (low-, medium-, highly-complex). The backbone of such categorization is ba
