Abstract  

We study the L p-saturation for the linear combination of Bernstein-Kantorovich operators. As a result we obtain the saturation class by using K-functional as well as some modulus of smoothness.

Abstract  

A system for Automatic NAA is based on a list of specific saturation activities determined for one irradiation position at a given neutron flux and a single detector geometry. Originally compiled from measurements of standard reference materials, the list may be extended also by the calculation of saturation activities from k 0 and Q 0 factors, and f and a values of the irradiation position. A systematic improvement of the SRM approach is currently being performed by pseudo-cyclic activation analysis, to reduce counting errors. From these measurements, the list of saturation activities is recalculated in an automatic procedure.

Abstract  

In this note we make a correction in the paper [1] by two of the authors. Specifically we modify an auxiliary localization result and prove that the applications to the saturation theory of some outstanding conservative operators remain valid. Moreover, we enrich a corollary dealing with the well-known Szsz-Mirakjan operators.

Abstract  

Hydroisomerization of n-hexane simultaneously proceeding with benzene saturation over platinum impregnated nano-crystalline zeolite beta (Si/Al = 25) at 1.0 MPa and 573–673 K was studied. The feed contained 30 wt% benzene. The synthesized catalyst was characterized by various techniques, e.g., powder X-ray diffraction, IR spectroscopy, thermal analysis, scanning electron microscopy and nitrogen adsorption. At the operating conditions used, total saturation of benzene with 95% selectivity to cyclohexane (CH) and methylcyclopentane (MCP) was observed. n-Hexane conversion increased with temperature whether benzene was present or not during the reaction. However, in the presence of benzene, n-hexane conversions as well as isomer selectivities were observed to be lower. This was attributed to reduced availability of acid sites by predominating benzene adsorption. Formation of carbenium ion on an acid site is questioned and plausible mechanism has been suggested.

For the hop varieties: Agnus, Harmonie, Premiant and Osvaldův klon 72, the values for the saturation radiance and photosynthetic capacity were determined. Photosynthetic capacity was determined gasometrically. For the varieties Premiant and Osvaldův klon 72 the saturation irradiance was 447 μmol.m −2 .s −1 and for the varieties Agnus and Harmonie 499 μmol.m −2 .s −1 . The lowest photosynthetic capacity was demonstrated by Osvaldův klon 72 (6.8 μmol CO 2 .m −2 .s −1 ) and the highest by Premiant (14.64 μmol CO 2 .m −2 .s −1 ). The results obtained supplemented the present knowledge from the area of hop physiology and will expand knowledge about the biological properties of the varieties in question.

In order to expand the experimental data set of models describing the movement of organic liquids polluting the soils, a series of experiments was set up in which the fluid retention (pressure- s aturation curves of the soils) were measured using water and NAPL (DUNASOL 180/220, a non aromatic petroleum product). Measurements were carried out on undisturbed soil samples originating from 35 different horizons of 12 characteristic Hungarian soils. The P-S curves with NAPL were determined in series, by a modified pressure cell apparatus - designed and constructed in the laboratory of our department - containing oil-resistant (silicon rubber, Teflon) components.   The applied methodology and the statistical analysis of the measured data are presented. The results show that the commonly used Leverett-type scaling of the water retention data provides inadequate estimation of the NAPL retention in some cases. This deviation may be a direct result of changes in clay volume and soil aggregation when saturation with different fluids was performed.  According to the analysis, however, with the easily measurable soil parameters (bulk density, particle size distribution and humus content) a better estimation of NAPL retention can be given. This estimation method (after extending the database) can be useful for modelling the fate and migration of NAPL or mapping the organic contaminant sensitivity of the soils.
