Organo-metal-halide (OMH) perovskites form a new class of materials withperovskite crystal structure ABX3 where A is an organic molecule, B is lead (Pb)and X is a halide atom (I or Br). OMH perovskite semiconductors have been widely used in photovoltaics due to their very strong absorption of sun light, very suitable electrical properties, and the ease of preparation. Today the power conversion ef

Purpose: While big data creates business value, knowledge on how value is created remains limited and research is needed to discover big data’s value mechanism. The purpose of this paper is to explore value creation capabilities of big data through an alignment perspective. Design/methodology/approach: The paper is based on a single case study of a service division of a large Danish wind turbine g

Natural resources, especially energy resources, are often considered vital to the process of economic development, with the availability of coal considered central for the nineteenth century. Clearly, however, although coal might have spurred economic development, development might also have spurred the discovery and use of coal. To shed light on this, we suggest that the case of resource-poor Den

This paper investigates the effect of educational mismatch of R&D workers on firm's returns to innovation. R&D labour mismatch emerges when R&D workers have competencies different from those required by their occupation providing a contribution to innovation lower than in the case of perfect educational matching. By estimating a knowledge production function on data for 13 manufacturin

The bacterium Wolbachia infects many insect species and spreads by diverse vertical and horizontal means. As co-inherited organisms, these bacteria often cause problems in mitochondrial phylogeny inference. The phylogenetic relationships of many closely related Palaearctic blue butterflies (Lepidoptera: Lycaenidae: Polyommatinae) are ambiguous. We considered the patterns of Wolbachia infection and

Based on international industry data between 1975 and 2007, this paper studies the production effects of upstream (service) regulation considering two different mechanisms of transmission: the productivity channel and the factor demand channel. The analysis shows that the effects of anti-competition barriers in service markets transmit to the rest of the economy varying with the technology conditi

Various proxy records have been used for the understanding of environmental and climate variations during the Holocene. Here, for the first time, we use meteoric 10Be isotope measurements performed on sediments from a drill core collected at the Kunlun Pass (KP) on the northeastern Qinghai-Tibet Plateau (NETP) to investigate hydroclimate changes during the Holocene. The 10Be flux suggests relative

The real antibiotic industrial wastewater with the characteristics of complex compositions, biological toxic, and degradation-resistant, is still biologically toxic to the ecosystem and human health even if the discharge standards have been met after treatment by traditional methods. Therefore, the biological harmless treatment of real antibiotic industrial wastewater is a valuable and meaningful

We consider Banach spaces of analytic functions in the unit disc which satisfy a weighted conformal invariance property, that is, for a fixed α>0 and every conformal automorphism φ of the disc, f→f∘φ(φ′)α defines a bounded linear operator on the space in question, and the family of all such operators is uniformly bounded in operator norm. Many common examples of Banach spaces of analytic functions

Background: Previous studies have proposed growth differentiation factor-15 (GDF-15) as a predictor of adverse cardiovascular outcomes and mortality. The present study aimed to determine if such associations remain after accounting for death as a competing risk, and if GDF-15 provides superior prediction performance than other biomarkers. Methods: Plasma GDF-15 levels and cardiovascular risk facto

Background: We have previously shown an association with substantially improved survival in breast cancer and melanoma for desloratadine and loratadine users, and set out to find whether an improved survival can be seen in tumors with and without a known response to immune checkpoint therapy, such as anti-CTLA-4 or anti-PD-1. Methods: We investigated survival and use of six common H1-antihistamine

The study evaluates the biogeochemical model ForSAFE-2D, designed to simulate water and chemical transport from the forest to the stream, by simulating the hydrology and the transport of the chemical tracer chloride (Cl−) along a forest hillslope in Northern Sweden. The simulated Cl− exports were in balance with the simulated inputs but measurements suggested a net release of Cl− from the catchmen

The field of studying EU external relations/actions has embraced and endorsed mainstream International Relations and European Integration theoretical orthodoxy over the past three decades. This ideological orthodoxy is proving catastrophic as the accumulation of economic, social, environmental, conflictual, and political crises are increasingly demonstrating. As Joseph Stiglitz succinctly puts it,

With well-structured chapters by leading scholars who explain key developments and concepts clearly, Islam and Popular Culture is the first comprehensive overview of this important subject

Background: Results on growth and nutrient intake in infants in the second half of infancy fed human milk or formulas with varying protein concentrations in combination with supplementary foods have not previously been reported. Methods: Seventy-one healthy infants were studied from 3 to 12 months of age. They were exclusively breast-fed until 3 months and were then randomly assigned to one of th

This chapter investigates how the challenging questions and tensions caused by migrants and their universalist claims for inclusion, have been approached and resolved in liberal democracies. By regarding the development of populism as a real and dangerous political phenomenon that has a significant traction, the chapter asks whether populism adds something new to this approach and resolution.

Det uppskattas att år 2050 kommer tio miljoner människor att dö av infektionersom inte kan behandlas på grund av att bakterier blivit resistenta ochdärmed gjort antibiotika ineffektiv. Denna typ av dystopier är en form avresor både bakåt och framåt i tiden, och där samhället beskrivs som någotannat än vad vi är vana vid. Tanken om en framtid utan antibiotika – enså kallad postantibiotisk era – går

Using a simple model based on the knowledge of spherical and deformed Woods-Saxon potentials, it is shown that the recent observation of halo phenomena in 29F can be interpreted as evidence for the prolate deformation of the ground state of 29F. The prolate deformation is the result of the shell structure, which is unique in one-neutron resonant levels, in particular near degeneracy of the neutron
