- Description:
- The condition of the protective barrier of the stomach in patients with duodenal ulcer associated and non-associated with H. pylori infection has been studied. The state of gastric mucosal barrier was studied in 72 patients with peptic ulcer disease association with H. pylori and 26 patients without H. pylori by determining the content of insoluble glycoproteins and its fractions in the basal portion of the gastric juice. In a comparative perspective the state of these indicators were studied depending on the association with H. pylori and the severity of the disease. In patients with H. pylori, damages of protective mucus barrier are characterized by the significant shortage of fucose, which is considered to be the main component of the insoluble glycoproteins. In patients without H. pylori, status of mucosal barrier is characterized by uniform and less significant reduction in the content of fractions of insoluble glycoproteins. In this patients the reduction of insoluble glycoproteins is not dependent on the frequency of exacerbation. The content of fucose in the mucous gel of gastric juice is a diagnostic criterion for determining the frequency of recurrence of the disease in patients with H. pylori infection., Abdujalol Vahabovich Yakubov, Nargiza Ihsanovna Pulatova, and Literatura

474203. The content of the body representations that guide everyday action
- Creator:
- Murillo Lara, Luis Alejandro
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- action, body representations, Merleau-Ponty, and non-conceptual mental content
- Language:
- Slovak
- Description:
- In this paper, I argue that activities as crossing the road, riding a bike or going through a door involve body representations with non-conceptual mental content. Firstly, I discuss some key objections to the notion of body representations for action, in order to draw out their main consequences. Then I introduce an approach to the content of body representations involved in the guidance of everyday action, which seems to satisfy crucial demands in exchange for moving away from conceptual views on mental content. I conclude by discussing a potential objection to that proposal and presenting some thoughts on the relationship between conceptual and non-conceptual content in this field.

474204. The continuing saga of β Lyrae
- Creator:
- Linnell, A. P.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- stars: binaries: eclipsing, stars: binaries: spectroscopic, and stars: individual: β Lyrae
- Language:
- Czech
- Description:
- This paper describes current efforts to model β Lyrae as an accretion disk system, using the BINSYN program suite. Initial analysis demonstrates that, on a zero-order approximation, only the mass loser and the accretion disk rim contribute significantly to the system luminosity, apart from the emission line region. This zero-order model fails to reproduce the OAO2 light curves. An elaboration providing a two-temperature rim does reproduce the OAO2 light curves. An elaboration providing a two-temperature rim does reproduce the principal details of the OAO2 light curves. However, the two-temperature rim model fails to simulate IR light curves. A suggested explanation is the presence of bremstrahlung radiation produced in coronal regions contiguous to the accretion disk. Synthetic spectra, on the same zero-order model, fit IUE spectra reasonably well but show discrepancies discussed in the text.

474205. The continuity of superposition operators on some sequence spaces defined by moduli
- Creator:
- Kolk, Enno and Raidjõe, Annemai
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- sequence space, superposition operator, modulus function, and continuity
- Language:
- English
- Description:
- Let $\lambda $ and $\mu $ be solid sequence spaces. For a sequence of modulus functions $\Phi =(\varphi _{k})$ let $ \lambda (\Phi )= \lbrace x=(x_{k}) \: (\varphi _{k}(|x_{k}|))\in \lambda \rbrace $. Given another sequence of modulus functions $\Psi =(\psi _{k})$, we characterize the continuity of the superposition operators ${P_{f}}$ from $\lambda (\Phi )$ into $\mu (\Psi )$ for some Banach sequence spaces $\lambda $ and $\mu $ under the assumptions that the moduli $\varphi _{k}$ $(k \in \mathbb{N})$ are unbounded and the topologies on the sequence spaces $\lambda (\Phi )$ and $\mu (\Psi )$ are given by certain F-norms. As applications we consider superposition operators on some multiplier sequence spaces of Maddox type.

474206. The continuous solutions of a generalized Dhombres functional equation
- Creator:

- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- iterative functional equation, equation of invariant curves, and general continuous solution
- Language:
- English
- Description:
- We consider the functional equation f(xf(x)) = ϕ(f(x)) where ϕ: J → J is a given increasing homeomorphism of an open interval J ⊂ (0, ∞) and f : (0, ∞) → J is an unknown continuous function. In a series of papers by P. Kahlig and J. Smítal it was proved that the range of any non-constant solution is an interval whose end-points are fixed under ϕ and which contains in its interior no fixed point except for 1. They also provide a characterization of the class of monotone solutions and prove a necessary and sufficient condition for any solution to be monotone. In the present paper we give a characterization of the class of continuous solutions of this equation: We describe a method of constructing solutions as pointwise limits of solutions which are piecewise monotone on every compact subinterval. And we show that any solution can be obtained in this way. In particular, we show that if there exists a solution which is not monotone then there is a continuous solution which is monotone on no subinterval of a compact interval I ⊂ (0, ∞).

474207. The contractible subgraph of $5$-connected graphs

- Subject:
- 5-connected graph, contractible subgraph, and minor minimally $k$-connected
- Language:
- English
- Description:
- An edge $e$ of a $k$-connected graph $G$ is said to be $k$-removable if $G-e$ is still $k$-connected. A subgraph $H$ of a $k$-connected graph is said to be $k$-contractible if its contraction results still in a $k$-connected graph. A $k$-connected graph with neither removable edge nor contractible subgraph is said to be minor minimally $k$-connected. In this paper, we show that there is a contractible subgraph in a $5$-connected graph which contains a vertex who is not contained in any triangles. Hence, every vertex of minor minimally $5$-connected graph is contained in some triangle.

- Type:
- model:article and TEXT
- Subject:
- critical argument, critical thinking, David Miller, dogmatic argument, fallibilism, falsification, inference to the best explanation, justification, Karl Popper, persuasion, and problem-solving
- Language:
- Slovak
- Description:
- Karl Popper lamented the prevalence of dogmatic argument in philosophy and commended the kind of critical argument that is found in the sciences. David Miller criticises the uncritical nature of so-called critical thinking because of its attachment to dogmatic arguments. I expound and clarify Popper’s distinction between critical and dogmatic arguments and the background to it. I criticise some errors in Miller’s discussion. I reaffirm the need for philosophers to eschew dogmatic arguments in favour of critical ones., Karl Popper naříkal nad převahou dogmatického argumentu ve filozofii a pochválil druh kritického argumentu, který se nachází ve vědách. David Miller kritizuje nekritickou povahu takzvaného kritického myšlení z důvodu jeho vazby na dogmatické argumenty. Vysvětluji a objasňuji Popperův rozdíl mezi kritickými a dogmatickými argumenty a pozadím. Kritizuji některé chyby v Millerově diskusi. Znovu potvrzuji, že je třeba, aby se filozofové vyhýbali dogmatickým argumentům ve prospěch kritických argumentů., and Danny Frederick

474209. The contribution of periodic comets to the zodiacal cloud
- Creator:
- Krasák, Ľ. and Krasáková, M.
- Format:
- bez média and svazek
- Type:
- model:article and TEXT
- Subject:
- astronomy, periodic comets, and zodiacal clouds
- Language:
- Czech
- Description:
- The dust production rates of all the known periodic comets, calibrated by the measurements from the 1986 apparition of comet Halley, are ušed to compute their dust input into the region inside the earth orbit, and the resulting dust fluxes at R = 1 AU. The spatial distribution of tho fresh ejecta and the teraporal variations of their accumulation are reconstructed. Tho visible release of dust is evidently insufficient to maintain the zodiacal cloud in equilibrium. It is suggested that the progressive decay of the dark matter, including extinct cometary nuclei, their fragments, and products of asteroidal collisions, represents the dominant source of replenishmont of the interplanetary dust complex.

- Language:
- English
- Description:
- The glycosaminoglycan (GAG) molecules are a group of high molecular weight, negatively charged polysaccharides present abundantly in the mammalian organism. By their virtue of ion and water binding capacity, they may affect the redistribution of body fluids and ultimately the blood pressure. Data from the literature suggests that the mitogens Vascular Endothelial Growth Factor (VEGF)-A and VEGF-C are able to regulate the amount and charge density of GAGs and their detachment from the cell surface. Based on these findings we investigated the relationship between the level of dietary sodium intake, the expression levels of VEGF-A and VEGF-C, and the amount of the skin GAGs hyaluronic acid and chondroitin sulfate in an in vivo rat model. Significant correlation between dietary sodium intake, skin sodium levels and GAG content was found. We confirmed the GAG synthesizing role of VEGF-C but failed to prove that GAGs are degraded by VEGF-A. No significant difference in blood pressure was registered between the different dietary groups. A quotient calculated form the ion and water content of the skin tissue samples suggests that - in contrast to previous findings - the osmotically inactive ions and bound water fractions are proportional., D.
