Multifractal analysis of biodiesel droplet imprints and estimation of the fractal surface energy of the spray

The multifractal (MF) analysis of the surface areas and the volumes of fuel spray droplet imprints, which formed on the surface of a glass plate covered with a soot layer, is presented. The input information for the MF analysis was obtained from photographic images of imprints of droplets of biodiesel, diesel and their mixtures. The parameters for the MF spectra of the surface areas and the volume

Multifractal spectrums for volumes of spatial forms on surface of ZnxCd1−xTe–Si (111) heterostructures and estimation of the fractal surface energy

Multifractal (MF) analysis is used to describe volumes of spatial forms that are formed on the surface of thin layers of ZnxCd1−xTe solid solution grown on the Si (111) substrate. MF analysis is performed on the basis of AFM images of the solid solution surface. The parameters of the MF spectrums for the distribution of volumes of the spatial forms, which formed the surface relief, were found. On

"Now the German comes": The Ethnic Effect of Gentrification in Berlin

Compared to the United States, the relationship between ethnicity and gentrification is still understudied in the Western European context. However, while Western Europe does not have the same racial history as the United States, ethnic and racial divisions are still expressed through urban inequality. This paper, a study of small-business owners in an ethnically stigmatized Berlin neighborhood, s

Innovation waves and technological transitions: Sweden, 1909-2016

There are important unresolved questions about long-term trends of in- novation activity and the nature of the interplay between innovation and economic development and transformation. This study explores the promise of a literature-based innovation output indicator, constructed for the Swedish engineering industry, 1909-2016. The findings suggest a long-run increasing trend in innovations per cap

Relative pollen productivity estimates in the forest steppe landscape of southeastern Romania

Estimates of relative pollen productivity (RPP) represent key input parameters for model-based quantitative reconstructions of past vegetation cover. In this study, we provide the first RPP estimates for 13 taxa from the forest steppe ecoregion in southeastern Romania (southeastern Europe). We used modern pollen assemblages from 26 points together with vegetation surveys and mapping, covering a 1.

Baltic Integration and the Euro

Which have been the consequences of the euro for integration and economic performance in the Baltic Sea region? After the collapse of the Soviet Union, the three Baltic states and Poland have been rapidly catching-up with Western Europe. The Great Recession became a great setback for the former, while less so for Poland. A difference is the monetary policy: the Polish zloty depreciated in the crit

α decay of high-spin isomers in N = 84 isotones

The superfluid tunneling model is applied to the calculation of half-lives of the observed α decays in N=84 isotones. Results of our calculations are compared to experimental data on the ground-state α decays along the isotonic chain from 144Nd to 159Re. Good agreement is found. The α decays of the known high-spin isomers in 155Lu, 156Hf, 157Ta, and 158W are also well reproduced, once a reduction

The impact of the glucagon-like peptide 1 receptor agonist liraglutide on the streptozotocin-induced diabetic mouse kidney proteome

In diabetes mellitus (DM), the kidneys are exposed to increased levels of hyperglycemia-induced oxidative stress. Elevated amounts of reactive oxygen species (ROS) are believed to provoke ultrastructural changes in kidney tissue and can eventually result in DM late complications such as diabetic nephropathy. While it is reported that glucagon-like peptide 1 receptors (GLP-1R) are present in the ki

A Seemingly Polynomial-Time Algorithm for Optimal Curve Fitting by Segmented Straight Lines

We consider least-squares approximation of a function of one variable by a continuous, piecewise-linear approximand that has a small number of breakpoints. This problem was notably considered by Bellman who proposed an approximate algorithm based on dynamic programming. Many suboptimal approaches have been suggested, but so far, the only exact methods resort to mixed integer programming with super

A global Bayesian sensitivity analysis of the 1d SimSphere soil-vegetation-atmospheric transfer (SVAT) model using Gaussian model emulation

Sensitivity analysis consists of an integral and important validatory check of a computer simulation model before the code is used in performing any kind of analysis operation. The present paper demonstrates the use of a relatively new method and tool for conducting global sensitivity analysis (GSA) for environmental models, providing simultaneously the first GSA study of the widely used 1d soil-v

Remote sensing input for regional to global CO2 flux modelling

The current and future strength of the terrestrial carbon sink has a crucial influence on the expected climate warming on Earth. Usually, Earth Observation (EO) by its very nature focusses on diagnosing the current state of the planet. However, it is possible to use EO products in data assimilation systems to improve not only the diagnosis of the current state, but also the accuracy of future pred

Testing the use of adjoints for parameter estimation in a simple GCM on climate time-scales

The paper presents a feasibility study for a Climate Prediction Data Assimilation System following the methodological approach of the Carbon Cycle Data Assimilation System (CCDAS). The usefulness of accurate gradient information for estimating process parameters of the spectral atmospheric circulation model PUMA on climate time-scales is investigated. Pseudo observations of the long-term mean surf

Impact of terrestrial biosphere carbon exchanges on the anomalous CO2 increase in 2002-2003

Understanding the carbon dynamics of the terrestrial biosphere during climate fluctuations is a prerequisite for any reliable modeling of the climate-carbon cycle feedback. We drive a terrestrial vegetation model with observed climate data to show that most of the fluctuations in atmospheric CO2 are consistent with the modeled shift in the balance between carbon uptake by terrestrial plants and ca

Anxiety and depression in breast cancer patients at start of adjuvant radiotherapy : Relations to age and type of surgery

Using a self-report questionnaire, the Hospital Anxiety and Depression (HAD) scale, feelings of anxiety and depression were assessed in 133 breast cancer patients referred for adjuvant radiotherapy following surgical treatment. Eighteen patients (14% had scores indicating morbid anxiety. Significant depression was recorded for only 2 patients (1.5% Severe anxiety was recorded for 10 out of 54 mast

Southern travelling habits with special reference to tumour site in Swedish melanoma patients

Southern travelling habits were recorded for 127 melanoma patients from southern parts of Sweden (the 56th latitude), 55 thyroid cancer patients, 100 non-Hodgkin's patients and 794 healthy controls from the same region. Melanoma patients were found to travel significantly more often south of the 45th latitude, as compared with patients with non-Hodgkin's lymphoma or thyroid carcinoma (RR = 2.2 for

Mina eller våra karaktärer?

De litterära karaktärerna är väsentliga för om läsarna ska engagera sig i en text och uppleva den som intressant och meningsfull, antingen man skapar egna karaktärer eller skriver fanfiction och diktar vidare på karaktärer som andra författare byggt upp. Gestaltningen är central och många unga ägnar sig åt att dikta vidare på kända verk, något som väcker frågan om vem som ”äger” de fiktiva karaktä
