Ever since the wars of the Yugoslav secession in the nineties, linguistic nationalism has proven to have been among the more relevant instances in the discursive construction of national identity and new languages, dubbed by Ranko Bugarski as ‘administrative successors’ of Serbo-Croatian. Even though contemporary linguistics still classifies Serbo-Croatian as one language with regional varieties (
Background: Heterotopic pregnancy with a combination of a caesarean scar pregnancy and an intrauterine pregnancy is rare and has potentially life-threatening complications. Case presentation: We describe the case of a 27-year-old white woman who had experienced an emergency caesarean delivery at 39 weeks for fetal distress with no postpartum complications. This is a report of the successful expect
Measured InGaAsSb/InAs nanowire TFETs showing both, sub-60mV/dec slope and high ON-current, are simulated using calibrated TCAD. The focus is laid on the impact of non-idealities, such as hetero-interface traps, oxide-interface traps, and bulk traps on device characteristics. Simulated temperature-dependent transfer curves are in good agreement with the measured data which validates the simulation
In Chile, 90% of the fish farms and major natural shellfish beds are located in the region surrounding the Inland Sea, where over the last few decades harmful phytoplankton blooms have often been observed. The onset and recurrence of bloom events are often related to the resuspension and germination of resting cysts that have accumulated in the sediments. The degree of cyst settling, accumulation
In this article, model predictive control is used to dynamically optimize an investment portfolio and control drawdowns. The control is based on multi-period forecasts of the mean and covariance of financial returns from a multivariate hidden Markov model with time-varying parameters. There are computational advantages to using model predictive control when estimates of future returns are updated
Background: Cystic fibros.000000 bacterial pulmonary infections and neutrophil-dominated inflammation in the airways. The aim of this study was to evaluate the neutrophil-derived protein Heparin-binding protein (HBP) as a potential sputum marker of airway inflammation and bacterial load. Methods: Nineteen CF patients, aged 6-18 years, were prospectively followed for 6 months with sputum sampling a
Objectives: One mechanism by which cartilage responds to mechanical load is by releasing heparin-bound growth factors from the pericellular matrix (PCM). By proteomic analysis of the PCM, we identified connective tissue growth factor (CTGF) and here investigate its function and mechanism of action. Methods: Recombinant CTGF (rCTGF) was used to stimulate human chondrocytes for microarray analysis.
The PI3K/mTOR pathway is the second most frequently deregulated pathway in a majority of cancers such as breast cancer, lung cancer, and melanomas as well as leukemia. Mutations in the genes coding for receptor tyrosine kinases (RTKs) and G-protein-coupled receptors (GPCRs) are quite common in all forms of acute leukemia. This can be a major cause of deregulation of the PI3K-mTOR pathway. To under
Background/Aims: We assessed how the novel PrisMax continuous renal replacement therapy (CRRT) system performed in a prospective international multicentre setting. We compared this device to its predecessor, the Prismaflex, with regards to multiple treatment parameters. Additionally, we performed a survey, aiming to measure user satisfaction. Methods: Data was prospectively collected from 7 intens
Isoprene is a highly reactive volatile organic compound emitted by vegetation, known to be a precursor of secondary organic aerosols and to enhance tropospheric ozone formation under polluted conditions. Isoprene emissions respond strongly to changes in meteorological parameters such as temperature and solar radiation. In addition, the increasing CO2 concentration has a dual effect, as it causes b
It is a textbook knowledge that charges of the same polarity repel each other. For two monovalent ions in the gas phase at a close contact this repulsive interaction amounts to hundreds of kilojoules per mole. In aqueous solutions, however, this Coulomb repulsion is strongly attenuated by a factor equal to the dielectric constant of the medium. The residual repulsion, which now amounts only to uni
Conventional agricultural practices can lead to soil erosion and a reduction in soil organic carbon (SOC) content. It has been suggested that less intensive agricultural practices, such as conservation tillage (including no-till and reduced till without soil inversion) may reduce both erosion and loss of SOC. The aim of this study was to determine whether, and why, conservation tillage is used in
Ignorance has only received scant attention in organization and management studies. This paper focuses on ignorance in an organizational context by presenting and analysing the lived experience of three managers who attempted to manage creativity. The analysis of the empirical material with the help of a detailed agency framework illustrates how the managers’ clearly articulated visions contradict

The optical properties of colored dissolved organic matter (CDOM) in surface waters are visible from space and observable throughout the water column in real time using in situ sensors. Due to their ease of measurement, CDOM optical properties are used as proxies for the quantity, quality and processing of dissolved organic matter (DOM) in natural waters. This talk will focus upon the use of these
The role of terrestrial organic carbon for recipient aquatic ecosystems is intensively researched. A multitude of studies now show that terrestrially-derived carbon supports a significant share (allochthony) of consumer biomass in many freshwaters. However, little is known about the mechanisms by which terrestrially-derived carbon is transferred to the level of metazoan zooplankton, and whether th
Many studies assume a respiratory quotient (RQ = CO2 produced per O2 consumed, by moles) of ~1 to calculate bacterial respiration from measured O2 consumption rates. However, the theoretical value of RQ varies with the elemental composition of the compound being decomposed. Photo-oxidation of DOC results in compounds of oxygen-rich organic acids which, theoretically, should result in elevated RQ.
Permafrost thaw can substantially increase the total export of dissolved organic carbon (DOC) to aquatic systems. The effects for bio- and photo-degradable DOC, however, are poorly known, because previous studies have mainly targeted lakes and streams which are indirectly affected by permafrost, while direct experimental work on permafrost thaw is lacking. We thus incubated permafrost cores from a
