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.

Plasma serotonin levels are associated with antidepressant response to SSRIs

Background: Less than half of patients with major depressive disorder (MDD) respond to their first antidepressant trial. Our understanding of the underlying mechanisms of selective serotonin reuptake inhibitors (SSRIs) remains poor, and there is no reliable method of predicting treatment response. Methods: Thirty-seven MDD subjects and 41 healthy controls, somatically healthy and medication-free f

Legacies of Loss : The intergenerational outcomes of slaveholder compensation in the British Cape Colony

Can wealth shocks have intergenerational health consequences? We use the partial compensation slaveholders received after the 1834 slave emancipation in the British Cape Colony to measure the intergenerational effects of a wealth loss on longevity. Because the share of partial compensation received was uncorrelated to wealth, we can interpret the results as having a causal influence. We find that

Challenging the proposed causes of the PCR plateau phase

Despite the wide-spread use of the polymerase chain reaction (PCR) in various life-science applications, the causes of arrested amplicon generation in late cycles have not been confidently identified. This so-called plateau phase has been attributed to depletion or thermal break-down of primers or nucleotides, thermal inactivation of the DNA polymerase, and product accumulation resulting in compet

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

Comparison of exhaustion symptoms in patients with stress-related and other psychiatric and somatic diagnoses

BACKGROUND: Several rating scales assessing stress-related symptoms of exhaustion have emerged in recent years. However, more knowledge is needed about the performance of these rating scales in patients with stress-related disorders as well as in other patient groups. With the recently developed Karolinska Exhaustion Disorder Scale (KEDS), we compared symptoms of exhaustion in different patient gr

Cognitive Load Drivers in Large Scale Software Development

Software engineers handle a lot of information intheir daily work. We explore how software engineers interact withinformation management systems/tools, and to what extent thesesystems expose users to increased cognitive load. We reviewed theliterature of cognitive aspects, relevant for software engineering,and performed an exploratory case study on how software engi-neers perceive information syst
