A triangular system of conservation laws with discontinuous flux that models the one-dimensional flow of two disperse phases through a continuous one is formulated. The triangularity arises from the distinction between a primary and a secondary disperse phase, where the movement of the primary disperse phase does not depend on the local volume fraction of the secondary one. A particular applicatio

The Soil and Water Assessment Tool (SWAT) model has been widely applied for simulating the water cycle and quantifying the influence of climate change and anthropogenic activities on hydrological processes. A major uncertainty of SWAT stems from the poor representation of vegetation dynamics due to the use of a simplistic vegetation growth and development module. Using long-term remote sensing-bas

Ruddlesden-Popper perovskites (RPPs) have been demonstrated as a very promising approach for tuning the emission color of perovskite light-emitting diodes (PeLEDs). However, achieving high-performance red PeLEDs with recommendation 2020 color coordinates is still challenging due to the lack of reasonable control over the properties of RPP films. Here, we demonstrate that the judicious selection of

ObjectiveGestational diabetes mellitus (GDM) is an established risk factor for developing type 2 diabetes mellitus (T2DM) that is possible to prevent by systematic follow-up and preventive measures. The aim of this study was to examine whether women with previous GDM were offered follow-up in primary care, according to Swedish national guidelines.DesignRetrospective review of electronic medical re

In this paper, we present an adaptive spectral projection based finite element method to numerically approximate the solution of the wave equation with memory. The adaptivity is not restricted to the mesh (hp-adaptivity), but it is also applied to the size of the computed spectrum (k-adaptivity). The meshes are refined using a residual based error estimator, while the size of the computed spectrum

A low leakage rate sealant of 10 wt% ZrO2-added CaO–K2O–Na2O–BaO silicate glass for SOFC has been studied. The structure of the sealant is stable at high temperatures with leakage rates less than 10−4 sccm∙cm−1, and no crystal except for ZrO2 is found in XRD analysis after heating at 800 °C for 100 h. ZrO2 is distributed in the glass matrix and plays a supporting role in avoiding over-softening at

Polybenzimidazole (PBI) is currently considered as a membrane material for alkaline water electrolyzers (AWEs), and has to be fed with highly concentrated aqueous KOH electrolytes in order to ensure sufficient electrolyte uptake and conductivity. However, the harsh operating conditions significantly limit the lifetime of PBI membranes. In response, we here report on the synthesis and performance o

The CO2 Human Emissions project has generated realistic high-resolution 9 km global simulations for atmospheric carbon tracers referred to as nature runs to foster carbon-cycle research applications with current and planned satellite missions, as well as the surge of in situ observations. Realistic atmospheric CO2, CH4 and CO fields can provide a reference for assessing the impact of proposed desi

A search for the dimuon decay of the Standard Model (SM) Higgs boson is performed using data corresponding to an integrated luminosity of 139 fb−1 collected with the ATLAS detector in Run 2 pp collisions at s=13 TeV at the Large Hadron Collider. The observed (expected) significance over the background-only hypothesis for a Higgs boson with a mass of 125.09 GeV is 2.0σ (1.7σ). The observed upper li

The International Accounting Standards Board (IASB) in January 2016 published International Financial Reporting Standards (IFRS 16), new guidelines on leasing standards with an effective date of January 1st, 2019. IFRS 16 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract, i.e. the customer (‘lessee’) and the supplier (‘le

During the 20th century storm damage in Sweden has increased as a consequence of how the forest has been managed, an increased proportion of forest and older tree stands. The increase of storm damage has consequences for the regional economy, infrastructure, foresters, and the society. At the same time the climate is gradually changing, which means increased temperatures and higher precipitation r

Antibodies have become immensely important reagents within biomolecular research and analysis as well as in medicine. Monoclonal antibodies are the largest class of biological drugs and with an increasing number of therapeutic antibodies approved for clinical use the need for efficient purification strategies is vast. Today, most antibodies are purified using affinity chromatography based on Prote

Instrumental analysis in metabolomics has proven to be a challenging topic due to metabolites having a wide spectrum of physiochemical properties and concentrations. The more conventional techniques in metabolomics include gas chromatography and liquid chromatography coupled with mass spectrometric (MS) detection. In most cases these techniques provide methods that are adequate for metabolomic res

Subsistence farmers in the developing world are one of the most vulnerable groups to the impacts of climate change. Strengthening their adaptive capacity requires information to inform their climate and agricultural-related decisions. Climate information services offer great potential to inform farmers’ decision-making, enabling households to strengthen their ability to manage climate-related risk

One of the major challenges in analytical chemistry is to find techniques and methods for determinations of low abundance compounds in complex sample matrices. This thesis describes the development of new miniaturised analytical techniques comprising capillary electroseparation combined with mass spectrometric detection. The techniques are rapid, sensitive, efficient, and suitable even for analyte

We study two-sided ("marriage") and general pairing ("roommate") problems. We introduce "sequences," lists of matchings that are repeated in order. Stable sequences are natural extensions of stable matchings; case in point, we show that a sequence of stable matchings is stable. In addition, stable sequences can provide solutions to problems for which stable matchings do not exist. In a sense, they

Popular Abstract in Swedish Klimakteriet är normalt en fysiologisk period som alla kvinnor upplever mitt i livet. Klimakteriet är inte en sjukdom eller sjukdomstillstånd utan en övergång ifrån en fertil period till en icke reproduktiv period och utgör för många kvinnor en milstolpe i livet. Övergångsåldern och de processer som föregår en ny balans kan ibland vara turbulent. Syftet med dessa studieMenopause is not a disease, but may bring about a wide range of health complaints and increase some risks of illnesses. The aim of this study was to evaluate the general health status and influences of background factors on symptomatology among a cohort of Swedish women aged 50-64 years, with specific emphasis on the effects of hormone replacement therapy (HRT) by investigating a profile of HRT us
