Opis:: A pulsed capillary discharge has been the subject of various experimental and theoretical studies. A jet of copperhydrogen plasma with a cylindrical symmetry has been developed as a light source for spectroscopic measurements. The electron density of the plasma was obtained by using the Hβ spectral line of the hydrogen component plasma. The electron temperature was determined by means of the Boltzmann method applied to the copper profiles emitted by the plasma jet. The copper and hydrogen lines were broadened principally by the Stark effect. The electron density of the plasma was found to be about 2×1017 cm–3 and the electron temperature about 20000K.

Opis:: Among all known inorganic pollutants of wastewater and natural water that adversely affect water bodies, different living organisms and human beings, iron compounds are the most common. Before discharging the wastewater into water bodies, it is important to remove iron ions from wastewater. The application of capillary materials in water and wastewater treatment is a promising direction of ecology and technology. The capillary properties of materials allow the development of quite simple, autonomous, highly efficient and energy-saving systems for water purification. The aim of the present paper was the investigation of the influence of the basic conditions of the filtration process with the application of capillary materia on the efficiency of iron ions removal. The initial concentration of the model solution, pH and temperature of the filtration process, as well as the contact area of the liquid phase with oxygen of the air were studied. The proposed method is appropriate for the treatment of water in the concentration range from 5 to 10 mg/dm3 with an optimum pH in the range of 4–7. The experimental data showed high efficiency of capillary materials application, providing sufficient removal of iron ions from low concentrated solutions, compared to the traditional method of precipitation. The main advantage of the capillary materials is the simplicity of their application, quite high degree of purification and there no need to consume electricity or additional reagents, which allows creating autonomous water treatment facilities and plants.

Opis:: In this paper, a porous medium is modelled by a network of converging-diverging capillaries which may be considered as fissures or tubes. This model makes it necessary to consider flows through capillary fissures or tubes. Therefore an analytical method for deriving the relationships between pressure drops, volumetric flow rates and velocities for the following fluids: Newtonian, polar, power-law, pseudoplastic (DeHaven and Sisko types) and Shulmanian, was developed. Next, considerations on the models of pore network for Newtonian and non-Newtonian fluids were presented. The models, similar to the schemes of central finite differences may provide a good basis for transforming the governing equations of a flow through the porous medium into a set of linear or quasi-linear algebraic equations. It was shown that the some coefficients in these algebraic equations depend on the kind of the capillary convergence.

Opis:: An analytical method for determination of pesticide Glyphosate in water as a combination of cation-exchange chromatography and capillary electrophoresis is presented. Pure water was spiked with Glyphosate at concentrations 0.1, 0.25, 0.5 and 1 mM and percolated through a strong cation-exchange column packed with Dowex 50WX4-400 resin in its H+ form. The extract was further analyzed by capillary electrophoresis in indirect detection mode. The calibration curve for the pesticide in the range 0.1–2.5 mM was linear and with high degree of reproducibility. The obtained recoveries for all the studied concentrations amount 85%. Afterwards, the possibility to determine Glyphosate at the concentration 0.001mM (0.17 µg/ml) was checked by percolation of 100 ml of water sample through a column. The calculated recovery was 97.7%

Opis:: Micro-bearings have many applications in computer devices, such as CPU fans or hard disc drives. So far, rolling bearings and slide bearings have been used,for example micro-bearing with smooth Journal and sleeve surface, which is known as FDB - Fluid Dynamic Bearing. Actually, latter versions of micro-bearings are being launched to the market: Ex-FDB - Extra Fluid Dynamic Bearing. This type of bearings was fabricated by putting some micro-grooves filled with oil on its interna! surfaces. Ex-FDB's are characterized by reduced level of generated noise and guarantee long failure-free fan life, reaching 120 000 hours. In this paper we present our numerical calculations of the friction force and the friction coefficient in the parabolic micro-bearing. Micro-bearing gap height is very low, often less then l micrometer, therefore capillarity and adhesion forces cause an increase of oil viscosity near the Journal and sleeve surfaces. Due to this fact a value of hydrodynamic pressure in micro-bearing gap also increases, what results in observed changes of capacity, friction forces and friction coefficient values. The influence of adhesion and capillarity on friction force and friction coefficient of oil in micro-bearing hasn't been considered from analytical point of view so far. This paper presents numerical results of computed values of friction forces and friction coefficient for parabolic micro-bearing in comparison to values for classical parabolic bearing.

Opis:: In all measurement systems of radiation, the detector is the most important part. We can say that it is the heart of these systems. Gas detectors are still the most popular type of detector. Modern technologies allow manufacturing gas detectors having a very good energy and position (2D) resolution, high efficiency, large effective area, small count rate effect, radiation hardness, good signal-to-noise ratio and not complicated structure. These detectors are very fast and can stably work for a long period of time. One advantage of gas detectors is the possibility to read not only charge, but also UV light generated in the detector. In this paper we want to make a review of construction, mechanical properties, performance and possible applications of the following so-called micropattern gas detectors (MPGD): microstrip gas chamber (MSGC), gas electron multiplier (GEM), MICRO-MEsh GAseous Structure (MICROMEGAS) and capillary plate detector (CP).

Opis:: Present paper shows the some main phenomena which have important influence on the micro-bearing operating parameters. To above mentioned phenomena belong: adhesion forces, adsorption forces, capillary forces, elastic and hyperelastic deformations of cooperating micro-bearing surfaces, Van-der Waals electrostatic forces on the micro-bearing surfaces. Because the height of super thin micro-bearing gap is very small often smaller than l micrometer, hence the adhesion forces and capillary forces arising in micro-bearing gap, provoke the oil dynamic viscosity changes. This fact leads to the hydrodynamic pressure and bearing carrying capacity changes. The performed research play off the main role of mechanical micro-deformations of cooperating micro-bearing surfaces on non-Newtonian oil dynamic viscosity and here are indicated the influence of capillary force on adhesion forces in micro-scale. The micro-deformations of the micro-bearing gap height are effecting the changes of oil flow velocity in the gap, this fact leads to the share rate changes and therefore we obtain changes of apparent viscosity of the non-Newtonian oil.

Opis:: In this paper, an analytical method for deriving the relationships between the pressure drop and the volumetric flow rate in laminar flow regimes of Newtonian and power-law fluids through symmetrically corrugated capillary fissures and tubes is presented. This method, which is general with regard to fluid and capillary shape, can also be used as a foundation for different fluids, fissures and tubes. It can also be a good base for numerical integration when analytical expressions are hard to obtain due to mathematical complexities. Five converging-diverging or diverging-converging geometrics, viz. wedge and cone, parabolic, hyperbolic, hyperbolic cosine and cosine curve, are used as examples to illustrate the application of this method. For the wedge and cone geometry the present results for the power-law fluid were compared with the results obtained by another method; this comparison indicates a good compatibility between both the results.

Opis:: The studies of the ultimate thermal flows have been carried out in metallic and poorly heat-conducting porous structures, which operate when gravitational and capillary forces act jointly and cool various devices of thermal power plants in order to create a scientific methodology. The mechanism of destruction of metal vaporizing surfaces and poorly heat-conducting coatings of low porosity made of natural mineral media (granite) has been described on the basis of the problem of thermoelasticity and experimental data. Thermal flow dependences on time of their action and depth of penetration of temperature perturbations were identified based on analogy. Capillary-porous systems have high intensity, heat transport ability, reliability, compactness. The results of calculations and experiment showed that the maximum thickness of the particles that detach under the influence of compression forces for granite coatings is (0.25÷0.3).10^-2 m. Sections of compression curves that determine the detachment of particles with dimensions of more than 0.3×10^-2 m for large thermal flows and short feed times, are screened by the melting curve, and in the case of small thermal flows and time intervals – the expansion curve.
