Let Ω \subset \mathbb{R}^{n} be a domain and let α < n − 1. We prove the Concentration-Compactness Principle for the embedding of the space W_{0}^{1}L^{n} log^{\alpha } L(Ω) into an Orlicz space corresponding to a Young function which behaves like (t^{n/n-1-\alpha }) for large t. We also give the result for the embedding into multiple exponential spaces. Our main result is Theorem 1.6 where we show that if one passes to unbounded domains, then, after the usual modification of the integrand in the Moser functional, the statement of the Concentration-Compactnes Principle is very similar to the statement in the case of a bounded domain. In particular, in the case of a nontrivial weak limit the borderline exponent is still given by the formula P: = \left( {1 - \left\| {\Phi (|\nabla u|)} \right\|_{L^1 (\mathbb{R}^n )} } \right)^{ - 1/(n - 1)} ., Robert Černý., and Obsahuje seznam literatury
31P MR spectroscopy was used to measure the signal intensity ratios of high-energy metabolites for the calculation of free cytosolic magnesium concentration [fMg2+] and pH in the calf muscles of patients with primary juvenile hypertension and of healthy controls. Surface coil and spectroscopic imaging techniques were used. In patients with hypertension, the concentrations of [fMg2+] was 788±33 mmol/l and intracellular pH was 7.05±0.02; these values were not significantly different from the results obtained in healthy controls ([fMg2+], 776±21 mmol/l and pH, 7.06±0.01). Biochemical assays of magnesium in the serum (S-Mg) and in urine (DU-Mg) confirmed this finding. Significant differences in the relative signal intensities of high-energy phosphates between patients with primary juvenile hypertension and healthy controls were observed: a) signal intensity ratios of PCr/Pi, PCr/PbATP, PDE/PbATP were increased, and b) Pi/PDe, Pi/PATP were decreased. The results were the same irrespective of whether the surface coil method or 31P spectroscopic imaging were employed., M. Hájek, D. Palyzová, M. Kořínek, D. Kurková., and Obsahuje bibliografii
In his book (2021) Trueman attempts to provide a solution to the problem of the concept horse, which according to Frege’s published writings is an object, not a concept. In the course of doing so Trueman rejects Wright’s response (1998) according to which some objects are also concepts, for example, the concept horse, so the categories are not exclusive. Trueman’s argument for exclusivity (Chapter 4) is the heart of the book, and as he says, it is his response to holders of differing views, like Wright. I think that there is a gap in Trueman’s argument which needs to be filled if Wright is to be considered refuted.
Since the beginning of hydrological research hydrologists have developed models that reflect their perception about how the catchments work and make use of the available information in the most efficient way. In this paper we develop hydrologic models based on field-mapped runoff generation mechanisms as identified by a geologist. For four different catchments in Austria, we identify four different lumped model structures and constrain their parameters based on the field-mapped information. In order to understand the usefulness of geologic information, we test their capability to predict river discharge in different cases: (i) without calibration and (ii) using the standard split-sample calibration/ validation procedure. All models are compared against each other. Results show that, when no calibration is involved, using the right model structure for the catchment of interest is valuable. A-priori information on model parameters does not always improve the results but allows for more realistic model parameters. When all parameters are calibrated to the discharge data, the different model structures do not matter, i.e., the differences can largely be compensated by the choice of parameters. When parameters are constrained based on field-mapped runoff generation mechanisms, the results are not better but more consistent between different calibration periods. Models selected by runoff generation mechanisms are expected to be more robust and more suitable for extrapolation to conditions outside the calibration range than models that are purely based on parameter calibration to runoff data.
The paper is based on a long-lasting research carried out among the members of Serbian ethnic/national minority in Hungary. The research focused on the topic of ethnic identity. This paper is an attempt to derive the actual concept of ethnic identity out of its results, together with the manner in which it is symbolized in the case of the observed group. The approach assumes that (eth-nic) identity is a socio-cultural construction, whereas the results are based on statements and behavior of the group members themselves - those who declare themselves as Serbs.
Conclusions of theoretical reasoning are assertions—or at least speech acts belonging to the class of assertives, such as hypotheses, predictions or estimates. What, however, are the conclusions of practical reasoning? Employing the concepts of speech act theory, in this paper I investigate which speech acts we perform when we’re done with an instance of a practical argument and present its result in a linguistic form. To this end, I first offer a detailed scheme of practical argument suitable for an external pragmatic account (rather than an internal cognitive account). Resorting to actual examples, I then identify a class of action-inducing speech acts as characteristic conclusions of practical argument. I argue that these speech acts—promises, orders, pieces of advice, proposals, and others—differ chiefly depending on the agent of the action induced (me, us, you, them) and their illocutionary strength.
