Features of the process of methanol partial and deep oxidation on supported copper catalysts as compared with silver samples have been studied. The influence of supports of different acid-base nature and modifying additives of Zr, Ce, La and Cs oxides on electronic states of supported copper was investigated by the methods of diffuse reflectance electron spectroscopy, XRD and electron microscopy. By comparison of catalytic and spectroscopic data a conclusion on the nature of active sites of copper catalysts in this process has been made.

In the paper, the effect of the pulse electron radiation on the stability of the colloidal iron solutions is studied. The work is performed on the standard test solutions which correspond to the real natural and waste water regarding their chemical composition. The irradiation was performed using the pulse accelerator TEA-500 with the electron energy 500 keV and pulse duration 60 ns. The dose was calculated using the potassium nitrate recommended for measuring the dose of the pulse electron radiation. The standard test solution used for radiation contained iron, silicon and humic substances ions in the correlation 5.6:20:2.2 mg/l, respectively. The solutions were subjected to radiation within the range of 0.6-5.0 Mrad. The efficiency of radiation was estimated by the variation in iron chromaticity and concentration in the initial and irradiated solution. The decrease in iron concentration and solution chromaticity after the radiation indicates the violation of the stability of the colloidal solution and the Fe(OH)3 coagulation sludge. To explain the interaction of the radiation with the colloidal particles, the water radiolysis mechanism was considered, since the most of the ionizing radiation energy is consumed for the interaction with the water forming a large spectrum of radiolysis products. In the paper we offer the interaction mechanism of hydrated electron and the colloidal particles on the ground that the hydrated electron has a much longer life compared to H and OH radicals and is formed with a large radiation-chemical output which is equal to 3.3÷3.5 ions per 100 eV. The lifetime of the hydrated electron is 2.3*10-4 s. Besides, the size of the hydrated electron is 0.38 nm that is much less than the size of micelle and because of these factors it interacts with the micelle nucleus. According to the literature data, the mechanism of the electron transfer to the micelle nucleus is accompanied with the violation of the double electrical layer, the destruction of the micelle forming the Fe(OH)3 sludge that was observed during the electron beam irradiation of the standard test colloidal solutions. In the paper we present the results on the effect of the ion nitrate on the kinetics of the variation in iron ion color and concentration in the standard test solution.

The “collector” method of uniaxial dry compacting homogeneously dense powdered bodies of complex shape without macroscopic defects has been developed. It was based on the self-alignment of uniform density regions within a green compact by design of special mold to reduce die-wall friction effects. An equation was proposed that determined the density differential throughout the height of a green compact, which depended on geometrical parameters, and required the controlled movement of die parts. The technique of pressing with the collector method has been developed and patented by TPU. Based on the principles of the collector method a compaction mold of spiral type was modeled for compaction of cylindrical compacts with two alternating, oppositely-moving parts of the passive shaping surface with sliders, twisted at an angle of 36 degrees. The process of powder compaction was simulated by finite element method. The simulation results of the deformation process in the compacts showed that the density of each layer distributed irregularly with the curvature of isosurfaces in the direction of movement of the punch. The results of comparative simulation showed that the statistical dispersion of local values of the deformation of the green compacts made by collector method with the mold of spiral type is reduced to 48% when compared with conventional static compaction and reduced to 5% when compared with collector compaction using the mold of non-spiral type. This method decreases the density gradients. It can be applied to manufacture ceramic articles from nanopowders like impellers and plates with longitudinal holes.

Nanosized La1-xCuxMnO3 (x≤0.1) was synthesized at different temperatures by using heteronuclear complexing method. X-ray diffraction analysis show that sample consists of two phases: La1-xCuxMnO3 (x≤0.1) having R3̅c space group with rhombohedral symmetrical structure and La2Cu2O5 having C2/c space group with monoclinic symmetrical structure. The results show the quantity of La1-xCuxMnO3 increase from 91.22 to 97.62%, while quantity of La2Cu2O5 compound decrease from 8.78 to 2.37% with rising of calcination temperature from 500°C to 900°C. The Photon Cross Correlation Spectroscopy (PCCS) was used to measure size distribution. The results reveal that particle mean diameter increases from (276±4) to (455±5)nm, particle specific surface area (Sv) decreases from 21.84 to 13.29 m2/cm3, particle size distribution equals to 55-761nm and particle surface and volume mean diameter (SMD, VMD) increase from 247 to 459nm.

A mathematical model of tree rings in the form of an interference pattern is presented. The model allows retrospective reconstruction of continuous radial growth of a tree during the entire vegetation season. The radial dependence of the wood density is considered as a certain oscillation whose phase is a strictly increasing function of radius. The radial growth is defined as a monotonic function of time, inverse with respect to the phase. Algorithms for model analysis are based on the condition of dispersion causality. Experimental results are discussed.

Using non-isothermal thermogravimetry (TG), the oxidation kinetics of oxygen-deficient lithium-titanium ferrospinel, Li0.649 Fe1.598 Ti0..5Zn0..2Mn0.051O4-δ, manufactured by ceramic engineering is investigated. The oxidation annealing of powder samples is performed in air. According to the X-ray phase analysis, the processes giving rise to variations in oxygen content occur within single-phase spinel structure. The experimental kinetic results are processed using the Netzsch Thermokinetics software. The oxidation rate constants and the effective coefficients of atmospheric oxygen diffusion into the ferrites are determined. The effective activation energy E of oxygen diffusion is found to be 1.95 eV. It is demonstrated that an increase in the oxygen non-stoichiometry parameter δ as a result of recovery annealing of ferrite powders in vacuum at T=1070 K for 2 hours gives rise to a slight decrease in E down to 1.89 eV. The activation energy of oxygen grain-boundary diffusion is identified by the electroconduction method. The resulting value 1.93 eV is fairly consistent with that obtained by TG.

Bangladeshi Vehicle License Plate Detection (BVLPD) plays an important and inevitable role in Vehicle License Plate Recognition (VLPR) system. The most challenging part of this method is to detect the region of the license plate from the vehicle image. In this paper, we propose an algorithm for analyzing the vehicle image to extract the LP position in the image of the vehicle. Initially, HSI color model is adopted to select a threshold for detecting candidate regions and then different geometrical properties of LP such as area, bounding box, aspect ratio are used to determine whether the candidate regions contain LP or not. Finally the candidate region is verified by intensity histogram. The proposed method is able to deal with candidate regions under different scale of the plate. In the experiment more than 100 images are used which are taken under different conditions such as uneven illumination, complex scenes, varied weather and varied distances from the vehicle to camera. The overall rate of success of the license plate detection algorithm is 85%.
