Bacterial and fungal response to nitrogen fertilization in three coniferous forest soils

Forest soil carbon (C) pools may act as sinks for, or sources of, atmospheric carbon dioxide, while nitrogen (N) fertilization may affect the net exchange of C in forest ecosystems. Since all major C and N processes in soil are driven by soil microorganisms, we evaluated the effects of N fertilization on biomass and bacterial and fungal activity in soils from three Norway spruce forests with diffe

Plant Size as Determinant of Species Richness of Herbivores, Natural Enemies and Pollinators across 21 Brassicaceae Species.

Large plants are often more conspicuous and more attractive for associated animals than small plants, e.g. due to their wider range of resources. Therefore, plant size can positively affect species richness of associated animals, as shown for single groups of herbivores, but studies usually consider intraspecific size differences of plants in unstandardised environments. As comprehensive tests of

Genetic variation in the GCKR gene is associated with non-alcoholic fatty liver disease in Chinese people

Recent genome-wide association studies reported that GCKR rs780094 polymorphism is associated with elevated fasting serum triglyceride levels and elevated levels of C-reactive protein (CRP). There are a ample of data on the association between circulating triglyceride, CRP concentrations and risk of non-alcoholic fatty liver (NAFLD). To determine whether the GCKR rs780094 polymorphism contributes

Neuronal Differentiation and Extensive Migration of Human Neural Precursor Cells following Co-Culture with Rat Auditory Brainstem Slices

Congenital or acquired hearing loss is often associated with a progressive degeneration of the auditory nerve (AN) in the inner ear. The AN is composed of processes and axons of the bipolar spiral ganglion neurons (SGN), forming the connection between the hair cells in the inner ear cochlea and the cochlear nuclei (CN) in the brainstem (BS). Therefore, replacement of SGNs for restoring the AN to i

Temperature-Dependent Exciton Dynamics in J-Aggregates-When Disorder Plays a Role.

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

New Public Management – ett enkelt penseldrag som förklarar det mesta?

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.

Detecting monomials with k distinct variables

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

Erythropoietin Receptor Expression Is a Potential Prognostic Factor in Human Lung Adenocarcinoma

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

Multiple effects of trace elements on methanogenesis in a two-phase anaerobic membrane bioreactor treating starch wastewater.

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

Förlåtelse, försoning och oförsonlighet i överlevandes berättelser efter kriget i Bosnien

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
