Absorption and fluorescence spectral properties of J-aggregates of core-tetrasubstituted perylene bisimide (PBI) dyes have been investigated in the temperature range from 300 to 5 K. A special feature of the present PBI J-aggregates is that, in contrast to classical J-aggregates like that of pseudoisocyanine (PIC), the chromophores are held together not only by van-der-Waals interactions but also

NPM bör inte användas som ett enkelt penseldrag med ambitionen att förklara komplexa problem, vinna gillande och locka folk till barrikaderna. Den här artikeln visar på ett antal risker som finns med dagens användning av begreppet i såväl populärdebatt som forskningsdebatt. Framför allt riskerar det att leda till en onödig polarisering och kraftiga förenklingar av komplexa problem.

We study the complexity of detecting monomials with special properties in the sum-product expansion of a polynomial represented by an arithmetic circuit of size polynomial in the number of input variables and using only multiplication and addition. We focus on monomial properties expressed in terms of the number of distinct variables occurring in a monomial. Our first result is a randomized FPT al

Recombinant human erythropoietins (rHuEPOs) are used to treat cancer-related anemia. Recent preclinical studies and clinical trials, however, have raised concerns about the potential tumor-promoting effects of these drugs. Because the clinical significance of erythropoietin receptor (EPOR) signaling in human non-small cell lung cancer (NSCLC) also remains controversial, our aim was to study whethe

For enhancing anaerobic membrane bioreactor (AnMBR) treating food processing wastewater due to speed-limited methanogenesis step, multiple effects of trace element (TE) supplementation on methanogenesis of a two-phase AnMBR were firstly investigated in batch tests. TE supplementation included individual element, combination and recovery of Fe, Ni, Co, Cu and Zn supplementation. Multiple effects of

I denna artikel analyseras berättelser av 27 överlevande efter kriget i Bosnien och Hercegovina. Artikelns syfte är att dels analysera markeringar för försoning och oförsonlighet, dels beskriva de försoningsvillkoren som aktualiseras i berättelser. Den interaktiva dynamiken under kriget konstruerar försoningen efter kriget som förbunden med krigstiden. Berättelser om försoning blir en arena för olIn this article I analyze verbally portrayed experiences of 27 survivors from the 1990s' war in Bosnia and Herzegovina. One aim of the article is to analyze markers for reconciliation and implacability, the second is to describe the terms for reconciliation which are actualized in those stories. The interactive dynamics, which occurred during the war, make the post-war reconciliation wartime assoc

The article deals with factors that can determine V°-to-I°-movement in Övdalian (älvdalska).

Background: Parkinson's disease (PD) is the second most common neurodegenerative disease, affecting similar to 5.2 million people worldwide. Continuous subcutaneous apomorphine (CSAI) represents an alternative treatment option for advanced PD with motor fluctuation. The purpose of this analysis was to estimate the cost-effectiveness of CSAI compared with Levodopa/carbidopa intestinal gel (LCIG), D

This text discusses different perspectives dealing with the impact of cultural studies on musicology within the context of word and music studies. The question under scrutiny is how the field’s foundation in word and music studies has been reconfigured by existing or changing academic structures. The text contends that the increasing emphasis on cultural studies in literary studies and musicology

In this work, the influence of substrate bias voltage on the microhardness, adhesive strength, friction coefficient, and wear rate of AIP Cr2O3 films deposited on AISI 304 stainless steel substrates was investigated systematically. In the meantime, the wear failure mechanism of AIP Cr2O3 films in dry sliding contact was also analyzed and discussed. The results showed that the mechanical properties
