Bevezetés: A szerzők ismertetik és elemzik a 2-es típusú, orális antidiabetikumokkal sikertelenül kezelt betegekkel lefolytatott DIABOBHU hazai obszervációs vizsgálat eredményeit. Célkitűzés: A vizsgálat során a diabetológiai gyakorlatban elindított glargin bázisinzulinnal kombinált orális kezelés eredményességét és biztonságosságát értékelték. Módszer: 2008–2011 között összesen 3955 beteg került bevonásra. Oktatást követően a betegek vércukor-önellenőrzés mellett titrálták fel inzulindózisukat a kezelőorvosuk segítségével. A 26 hetes vizsgálati periódusban 3 vizitre került sor. Elsődleges végpontként a HbA1c-szint változása szerepelt négy korcsoportban. Másodlagos végpontként az éhgyomri vércukorértékek, az inzulin dózisa, a testsúly, testtömegindex változása, a kezeléssel kapcsolatos megelégedettség, a hypoglykaemiák incidenciája szerepelt. Eredmények: A kiindulási átlagos 8,94%-os HbA1c 7,31%-ra csökkent. A betegek többsége elérte a glykaemiás célokat igen alacsony hypoglykaemiaráta mellett. A vizsgálat eredményei közül kiemelendő, hogy a betegek testsúlya nem nőtt és kezelésükkel elégedettek voltak. Következtetések: A szerzők hangsúlyozzák, hogy az analóg bázisinzulinnal kombinált orális kezelés ma is hatékony és biztonságos terápiának számít. Orv. Hetil., 2014, 155(23), 903–910.

Summary A class of numerical measures of informativity of observation channels or statistical experiments is defined by the aid off-divergences introduced by the author as measures of difference of two probability distributions. For observation channels with given prior probabilities, thef-informativity measures are generalizations of Shannon's mutual information and include Gallager's functionE 0(ϱQ) appearing in the derivation of error exponent for noisy channels, as well. For observation channels without prior probabilities, the suggested informativity measures have the geometric interpretation of a radius.

Abstract  

Hydrogen abstraction from methylene chloride by the.OH radical in aqueous solution is monitored by direct observation of the.CHCl2 radical absorption build-up at 220 nm, yielding a bimolecular rate constant of /5.8±0.2/xlo7 M–1s–1 at room temperature. A spectral band extending from 220 nm to 330 nm is assigned to the dichloromethyl radical.

Abstract  

This work presents the performances of a new apparatus developed for thein-situ observation of a freeze drying (lyophilization) phenomenon. The results obtained on the lyophilization kinetics performed on a standard mixture (aqueous saturated NaCl solution) are presented.

It is widely reported that the productivity-richness relation (PRR) is highly variable, and several field studies suggest that the PRR varies with observational scale. Here we provide the first experimental study to test whether the PRR is scale-dependent when all replicate ecosystems have similar initial conditions. We also test the relation between productivity and compositional dissimilarity, and whether the PRR varies with ecosystem size. Moderately complex replicated microcosms were assembled consisting of a range of protozoa, algae, and a diverse bacterial flora. We found that the PRR of protozoan and algal communities varied with observational scale, but was unrelated to ecosystem size. Specifically, protozoan and algal richness increased monotonically with productivity at the local scale, but became flattened at the regional scale. This varying PRR at different scales occurred because dissimilarity among replicates decreased with productivity. Thus, in this model system, our experimental approach found a different form of scale dependence than previous field research. We speculate that this difference results from different processes governing extinctions at low levels of productivity.

Abstract  

An activation analysis procedure has been suggested which includes correction of the measurement time in accordance with the normalized error by processing the date during observation with subsequent optimization of the activation and cooling times. Such a procedure enables one to intensify the analysis providing the analytical error is normalized. A mathematical description of the procedure is given, and the optimization of the components of the measurement and their treatment in accordance with the normalized error is performed. This procedure is most efficient for analysis of a great number of samples similar in elemental composition, i.e. in systems used in industry. The measurement may also be applied in scientific studies. The features concerning application of the optimized measurements in activation analysis with various sources of activating particles, as well as in other radioanalytical methods, are considered.

Abstract  

High pressure experiments have been performed by thermobarometric analysis on two homologous (n=10 and 11) of the [3-fluoro-4((R) or (S)-methylheptyloxy) 4′-(4″-alkoxy-3″-fluorobenzoyloxy) tolans series, which both exhibit the TΓBA phase. The character (first or/and second order) of the transitions involving the TGBA phase are determined from thermobarograms. The pressure-temperature phase diagrams show that the TGBA phase is stabilized under high pressure for the two compounds. Forn=11 an inducedS A phase is observed under high pressures leading to the first experimental observation, on pressure-temperature phase diagram of pure compounds, of aS C * -S A-TGBA multicritical point, previously predicted by the Renn-Lubensky theory.

. Sample size was negatively associated with the prevalence of IAD. Although there was no known external factor that could lead to a systemic distortion in smaller studies, the results of these studies may be relatively unstable. However, this observation

Systematic earthquake data collection in the Pannonian region started early in the nineteenth century. Officially organised collection and evaluation of earthquake data started in 1881 when the Permanent Earthquake Committee was founded within the Hungarian Geological Society. We can regard this Committee as the ancestor of the Seismology Department of the Geodetic and  Geophysical Research Institute (GGRI). Today the Observatory Division of the Seismology Department of GGRI (in short: Seismological Observatory) gathers instrumental and macroseismic earthquake data and also deals with determination of earthquake focal parameters, among other tasks. The Seismological Observatory operates 7 stations in the country. Six of these stations are very broadband ones with near real-time accessibility of data. Based on the national seismograph station network and also integrating data from agencies of neighbouring countries our Division localises 80-100 local earthquakes annually. The relatively numerous localised earthquakes serve a base for, among others, crustal structure studies and also for more precise earthquake hazard evaluation.
