The main goal of this research is medical waste, scientific classification and their treatment in Ukraine. The results based on analyses of different types of classification. The new classification had been done according of three categories. There are waste from veterinary clinics; human waste of medical institutions and municipal waste. Waste from veterinary clinics is specific category because contains specific microbes, toxins animal and vegetable origin. The municipal waste also consists on all types of medical waste except of nuclear and located on the dumping place. The danger medical waste must be separate and isolated from the general part of municipal waste and subjected to recycling. The principles of treatment: removal, destruction, disposal after disinfection, industrial processing had been proposed depends on ecological situation and component compounds. This classification is key element of the management system of medical waste.
We present firstly a new whole technique of analysis, processing and forecasting any time series of the chemical pollutants in the typical hydroecological systems , which is schematically looked as follows: a). A general qualitative analysis of dynamical problem of the typical hydroecological systems (including a qualitative analysis from the viewpoint of ordinary differential equations, the “Arnold-analysis”); b) checking for the presence of a chaotic (stochastic) features and regimes (the Gottwald-Melbourne’s test; the method of correlation dimension); c) Reducing the phase space (choice of the time delay, the definition of the embedding space by methods of correlation dimension algorithm and false nearest neighbor points); d). Determination of the dynamic invariants of a chaotic system (Computation of the global Lyapunov dimension λα; determination of the Kaplan-York dimension dL and average limits of predictability Prmax on the basis of the advanced algorithms; e) A non-linear prediction (forecasting) of an dynamical evolution of the system. The last block indeed includes new (in a theory of hydroecological systems and environmental protection) methods and algorithms of nonlinear prediction such as methods of predicted trajectories, stochastic propagators and neural networks modelling, renorm-analysis with blocks of the polynomial approximations, wavelet-expansions etc.
The formation of conditions of aquatic ecosystem in the Black Sea shelf including the level of pollutant in the bottom sediments had been examined during the last 30 years. Comparison of current data with the data of the late 20th century and their variability has been performed. In addition to this negative phenomenon a lot of contaminations and pollutant are taking out by river run off into the sea. In the process of sedimentation suspended matter into the bottom sediments is accumulated. It worsens the negative condition of the benthos organisms. It is the reason to see this problem using data base and possible literature to analyze the intensity, accumulation and distribution pollutants: heavy metals, oil in the Black sea shelf. In the Nothwestern Black Sea shelf significant increasing, by two orders, of copper, lead, and nickel concentrations in the bottom sediments compared with 80-ths in a period of 1991 – 2013 had been marked.
Foreign experience of classification and preservation of especially valuable lands has been analysed. It has been offered to distribute agricultural lands by five value categories of these lands: ‘the first principal’ category includes the best agricultural lands according to item 1 a of Article 150 of the Ukrainian Land Code; ‘the second principal’ contains unique agricultural lands and the lands of experimental fields of scientific research and educational institutions; ‘the first additional’ includes valuable agricultural lands within the country; ‘the second additional’ comprises agricultural lands of local significance; and ‘additional’ consists of lands that are not appropriate for agricultural production. Withdrawal (or redemption) of the first three land categories is possible either in accordance with the resolution of the Ukrainian Cabinet of Ministers or by the decision of the corresponding local council on condition that the issue about withdrawal (or redemption ) comes to and agreement with the Supreme Rada of Ukraine. Withdrawal (resolution ) of lands of the last two categories is possible according to the resolution of the Regional Land Resources Management Agency. On the example of the Izmail natural-agricultural region, the soils distribution of lands of agricultural designation is conducted by value categories.
We present an improved generalized approach to the analysis and prediction of the nonlinear dynamics of chaotic systems based on the methods of nonlinear analysis and neural networks. As the object of study are the hydroecological systems (pollution dynamics). Use of the information about the phase space in the simulation of the evolution of the physical process in time can be considered as a major innovation in the modeling of chaotic processes in the hydroecological systems. This concept can be achieved by constructing a parameterized non-linear function F (x, a), which transform y (n) to y(n+1) = F[y(n),a], and then use different criteria for determining the parameters a . Firstly to build the desired functions it is offered using the wavelet expansions. Further, since there is the notion of local neighborhoods, we can create a model of the process occurring in the neighborhood, at the neighborhood and by combining together these local models to construct a global non-linear model to describe most of the structure of the attractor.
An improved theoretical scheme for sensing temporal and spatial structure of the chemical pollution substances in the forested watersheds is theoretically investigated and applied to an analysis and modelling the concentrations of phosphates and nitrates. The effects of stochasticity and chaotic features in the chemical pollution structure of the watersheds are discovered on the basis of the correlation dimension approach to empirical time series data. As the concrete example, there are studied a dynamics of the daily values of the concentrations of phosphates and nitrates, water flows (forested watershed Maleno, Small Carpathians, Slovakia) in 1991/1992 years and the relationship between the correlation dimension and embedding dimension is computed. The finite correlation dimensions obtained for the two series indicate that they all exhibit chaotic behaviour. The presence of the deterministic chaos elements at each of the two studied scales suggests that the dynamics of transformation of the chemical pollution component between these scales may also exhibit chaotic behaviour. This, in turn, may imply the applicability (or suitability) of a chaotic approach for transformation of the the pollution component data from one scale to another. Thus, for hydroecological systems it can be principally possible a scenario of so-called automodelity.
Introduction. In the conditions of modern climate change, interest to study of tendencies shaping of future wind regime and its extremal manifestations, and also use of wind energetic possibilities instead of the traditional, already limited stocks of oil, gas and coal, makes priority forecast of the future state of atmosphere.
The purpose of this publication is a study of the dynamics change of circulation processes over the territory of Ukraine using typification of synoptic situations over the specified region during the period 1992-2012.
Methods. As the starting materials used catalog types of synoptic processes over the territory of Ukraine for the period from 1992 to 2012 for the central months of the season, and the calendar of elementary circulation mechanisms (ECM) Dzerdzeevskogo B.L. For specification synoptic situations were also used weather maps of all levels.
Results. The structure of the macrocirculation conditions typical for Ukraine, including the regional characteristics of synoptic processes that lead, in conjunction with local physiographic conditions, to the establishment of the wind regime, reduced to six basic types and 17 subtypes. This includes: peripheral atmospheric processes, cyclonic and anticyclonic circulation, weakly gradient fields of pressure, peripheral atmospheric processes connected with passage of atmospheric fronts and cyclonic circulation with great pressure gradient. The authors analyze the changes of the circulation conditions for various seasons , as well as their connection with the types of ECM.
Conclusion. Conducted analysis of dynamics synoptic processes over the territory of Ukraine and the ECM for a twenty-year period allows you to: identify the most possible atmospheric processes, that form the weather conditions in Ukraine in recent decades; determined processes and types responsible for the observed intensification of wind speed and increasing the intensity of extreme weather events associated with the wind.
Directions for further research should include the following. Supposed to illustrate the relationship of synoptic processes and types of ECM over Ukraine with different indexes of circulation, such as A.L. Katz, the Arctic oscillation (AO), the North Atlantic oscillation (NAO), and others, during the study period.
We present the elements of a new advanced non-stationary theory of global mechanisms in atmospheric low-frequency processes, the balance of the angular momentum of the Earth, teleconnection effects and atmospheric radio waveguides. The theory is realized and implemented into Microsystem Technology “Geo-Math” and focused on the discovery and testing of new predictors for long-term and very long-forecasts of low-frequency atmospheric processes. The PC experiments have demonstrated an effectiveness of a new advanced theory in application to modeling balance of angular momentum, the atmospheric moisture turnover in relation to the genesis of tropospheric radio waveguides and succession processes of atmospheric circulation forms (teleconnection, front-genesis) in order to develop new practical sensors in long-term forecasting and modeling of low-frequency atmospheric processes. It is determined a link of tropospheric waveguide with atmospheric moisture circulation and, accordingly, with the shape of the atmospheric circulation over the position of the front sections of (atmospheric fronts as the main drives moisture). Atmospheric moisture cycle is linked with such typical low-frequency process as the angular momentum balance; the latter accounts violation of the atmosphere rotating balance with the Earth, which may be under developing meridional processes with the implementation of the mass transfer of air and steam between the tropical latitudes (with a large linear velocity) and slowly rotating air masses of the polar latitudes (a process of slow teleconnection).
Introduction. Studies in the field of climate changes of the Earth and its regions are one of the main priorities for Earth science in recent years. Among numerous works on the “global warming” subject, the direction, in which close attention is paid to the study of mechanisms and causes of dynamics of quasistationary atmosphere action centers and atmospheric circulation indices, is recently formed.
Results. In the paper the features of the statistical structure of surface atmospheric pressure fields in the Northern Pacific are described for the period of 1957-2014. The seasonal dynamics of atmospheric activity centers such as Aleutian Depression and Honolulu High are studied. For systems of baric centers in the Pacific Ocean development of its characteristics in natural orthogonal functions are carried out. The principal components of the fields of atmospheric surface pressure are obtained and their statistical analysis is conducted. Using the Fourier transform method, statistically significant hidden periodicities are revealed in the time series of the principal components. By means of smoothing of time series of the principal components, long-term fluctuations and trends are determined.
A research aim are an exposure and analysis of terms that influence on adjusting of quantity of prattle moth on east of Ukraine, where the quantity of him grows the last years. For the achievement of this aim it was necessary to decide such tasks:: to study de-scription of climatic features of territory of расселения of prattle moth; to give environmentalist biological description of terms of development of wrecker; determination factors that influence on a quantity and distribution of wrecker. Meadow butterfly is one of the most dangerous pests of vegetables, tilled crops, perennial grasses and pastures. His strength is changing dramatically as in some years and for some generations. Depending on the area of climate and weather conditions this year meadow moth has from 1 to 4 different generations and uneven pace of development in various fields.This paper describes the study of the influence of agro meteorological conditions on the development of meadow butterfly populations in Eastern regions of Ukraine.
Blocking as a large-scale steady atmospheric process is a main reason of weather anomalies existing at weekly and seasonal time scales. It is very interesting to study these processes in view of medium and long-term weather forecasts, atmospheric processes modelling and climate monitoring. There are presently a large number of papers considering climatic features of atmospheric blocking. However the methodological differences in methods of blocking processes detection, the lack of common methods, and differences in the length of studied periods make difficulties for a climatic generalization of blockings. This article aims, on the one part, to review the existing methods suitable for the recognition of blocking processes and, on the other part, to offer an approach which uses the dynamic nature of blocking as basis. According to Tyrlis and Hoskins (2007), the basic characteristic of blocking is considered to be potentially warmer air being found at higher latitudes, i.e. the usual situation is reversal. Also, the spatial scales and duration of real blocking are larger than those for usual synoptic processes; these characteristics can be considered as additional. As a result, an inter-pretation of the basic blocking requirement is that large-scale wave breaking at the tropopause level is occurring. If consider the evolution of Rossby waves as a usual situation for the formation of blocking anticyclone in the troposphere, the 500-hpa geopotential height map can show that a horizontal axis of the baric ridge is oriented from southern west to northern east in the case of anticyclonic wind shear and from southern east to northern west in the case of cyclonic one. Both these configurations allow the atmospheric blocking by using different approaches to the calculation of blocking indices. The proposed approach was used to study and classify atmospheric blockings in Europe during the period from 1998 to 2008.

The chemical composition of natural water determines in front him the story, that way, taken with water during their cycle. Dissolved substances in such water will depend, on the one hand, the composition of the substances with which it faced the other – on the conditions in which these interactions occur. To influence the chemical composition of water can the following factors: rocks, soil, living organisms, Liu activity Rights, climate, topography, water regime, vegetation and hydrodynamic conditions that natural and anthropogenic factors

Introduction. At present critical environmental situation on Kuyal’nik Liman can be stated. The main danger for the estuary is its gradual drying. That is the result of global warming, reduction rivers inflow, sand extraction on its shores. Actuality of the work caused by the need of determining the future state of water resources of Kuyal’nik Liman watershed under global climate changes on the base of climate scenarios.
The aim of investigation is choice of global warming scenario (A1B or A2), the data of which have the great agreement with actual data.
Research methods. Method of calculation is based on a mathematical model “climate-runoff “, developed at the Odessa State Environmental University.
The main results. For determination of possible climate change scenarios A1B and A2 were selected. For modeling the air temperature and precipitation on meteorological stations Odessa, Razdel’naya, Zatish’e, Lyubashevka were used. Temperature regime is described with the same accuracy according to the both model REMO (scenario A1B) and the model RCA3 (scenario A2).

The characteristics of the contemporary hydrochemical regime of Tyligulskiy Liman are presented on the basis of field observations (2002-2015) data analysis. Compared with the early 1980s, the concentration of ammonia nitrogen in the liman has significantly decreased, while that of mineral phosphorus has increased. The natural balance between mineral compounds of nitrogen and phosphorus in the liman’s waters has been significantly disturbed in favour of phosphorus. This is a typical feature of the contemporary hydrochemical regime of the liman. Currently, the primary production of organic matter in the liman is constrained by relatively low concentrations of mineral nitrogen. The low delivery capacity of the “liman-sea” artificial connecting canal and its mode of operation have resulted in the accumulation of mineral and organic phosphorus compounds in the liman over the years. Significant supply of nutrient compounds and organic matter has accumulated in the sediments of the liman. It is concluded that an increase in the influx of either marine or river water into the estuary could favour an increase of organic matter concentrations in ecosystem. However, with an increase of the connecting canal delivery capacity, nutrients will not only enter the liman and accumulate in it but also propagate from the liman into the sea as a result of differently directed water exchange under the influence of fluctuating water levels in the liman and the sea, caused by wind.
Introduction. The overview is composed on the base of materials that was received as result of regular stationary hydrometeorological and expedition oceanographic observations at sea coastal zone executed in 2013 and 2014.
Purpose. Hydrometeorological situation in the sea coastal zone has tendency for significant changes due to the climate processes. The aim of this work is to estimate the changes at the last two years. Methods. In the article used results of observations of hydrometeorological characteristics received by standard methods during observations at the sea coastal zone.
Results. At 2013 span of sea level variability was 80 cm. Year average sea level was 487 cm, that isn’t differ from average value for 2003 – 2012 (486 cm). Year average sea level at 2014 was 484 cm. Range of daily average value variation was 67 cm. Water warming-up at May-June also water cooling at September-October was occurred more intensive at 2013 than 2014. Average values of water temperature at 2013 and the average value for 2003-2012 was almost equally – accordingly 12,4ºC and 12,5ºC.At summer season of 2014 water warming-up in the sea coastal zone was so intensive, that average water temperature exceeded similar value at 2013 for 4,5ºC and average long-term value for 2,5ºC.Frequency of storm waving at 2014 was the most for the last 15 years. If year average storm waving frequency at 2003 – 2012 was10 %, at 2013 it was 9,6 %, at 2014 it was 15,8 %.
Conclusion. Climatic conditions and characteristics of the main elements of hydrometeorological regime in the sea coastal zone at 2013 for some exeptions was close to the medium level for the last ten years. At 2014 was the deep warming-up of water, increasing of wind activity, large amount of rainfall loss for the short term that caused significant floods.
We propose a new serial, single quantum-mechanical approach to the problem of quasi-stationary states, including both the Stark effect and the scattering problem at all. The approach allows the calculation of complex energy resonances and is particularly useful in the study of the spectral region near the boundary of the new continuum. We have developed a method of describing quasi-stationary states, in principle, devoid of all the shortcomings of the existing quantum-mechanical methods for solving the problem based on the Stark and operator formalism of perturbation theory. Its essence – the inclusion of a well-known in the theory of scattering “distorted waves” approach within the formal precision of perturbation theory. The proposed new method can be used to explore the resonances of any nature. Currently it is used by us to the study of resonances of the compound – nucleus formed by the collision of heavy ions. Unlike other approaches, it allows to calculate not only the function of the scattering states, but also to determine the function of the state with complex energy plus a full complement of functions orthogonal scattering.
We present the elements for a new, precise theoretical approach to the description of hyperfine and weak interactions in heavy Fermi systems, which is based on the new combined-formalism of relativistic nuclear and QED perturbation theory with precise taking into account the radiation and correlation effects. There шы e presented the estimates of the nuclear spin dependent contributions into the parity non-conservation amplitude of the transitions, in particular, due to an anapole moment of the nucleus. The obtained results are compared with the data of nuclear shell and other models. The new nuclear QED TV made payment of contributions at PNC amplitude EPNC, independent of the nuclear spin, particularly related to the interaction through the exchange of Z bosons, due to nuclear axial vector (AnVe) shock, the combined effect of the hyperfine interaction and spin –independent Z sd exchange interaction caused by the vector (VnAe) currents of nucleons, and finally, the main source – anapole moment of the nucleus (~ ka). A comparison with alternative data obtained on the basis of MBPT-DF theory (Johnson – Safronova), in the framework of the nuclear shell model Flambaum-Murray and Haxton et al, as well as evaluating DF Bouchiat-Piketty.
General issues of electronic conductivity and the causes for the current flow, role of electrochemical potentials, Fermi functions, and Fermi window for conduction are discussed, as well as there given detailed description of the Landauer elastic resistor model, different transport regimes from ballistic to diffusion and in between, conductivity modes, and transmission coefficient in the frame of the «bottom – up» approach of modern nanoelectronics. Generalized model of electron transport in the linear response regime developed by R. Landauer, S. Datta, and M. Lundstrom with application to the resistors of any dimension, any size and arbitrary dispersion working in ballistic, quasi-ballistic or diffusion regime is summerized.
In summary, the Landauer equation for the conductivity describes the electron transport in the conductor from the very general positions. The conductivity is proportional to the fundamental constants q and h, which determine the quantum of conductance, associated with contacts. The conductivity depends on the number of modes of conductance and transmission coefficient, representing the probability that an electron with energy E injected by one contact to reach another contact. Conductivity we finally find by integrating the contributions from all modes of conduction. The equations valid for 1D, 2D and 3D conductors for ballistic nanoreactors as well as for massive conductors.
The theoretical description of the local structure of granular materials has been performed by means of Voronoi method. The detailed investigation of structure transformations has been carried on with help of Voronoi tessellation supplemented by direct modeling of the relevant distribution function in terms of classical moments theory. Analytical expression for distribution function of Voronoi figures has been constructed with the help of Nevanlinna’s formula from theory of orthogonal polynomials .Proposed approach permit to avoid the problem of week argumentation of applicability the statistical mechanics methods for description of the structure and physical properties of granular materials. We show that generated ordering in local structure are escorted by appearing of particular symmetries in Voronoi diagrams. We perform a numerical simulations of structural configurations in 2D system of hard discs. Proposed algorithm allow us to prove theoretical predictions about existence of correlations between configurational ordering and symmetry breaking in Voronoy tessellations. We study these effects in the vicinity of jammed states. Obtained results shows that criticality in structurisation (formation of jammed states)connected with particular behavior of the first two moments of Voronoi figures distribution function. We show nonhomogeneous character of jammed states in which kinematic freedom degrees become frozen. Namely, coexisting ordered domains which has a different symmetries in grain configurations are observed. Therefore given analysis fulfill the basis of research in the area of granular physics which are mostly based on the concepts of probabilistic stereology and do not use methods from statistical mechanics which in the case of granular materials are not enough argumeneted.
On the basis of experimental studies and theoretical curves selected, we developed a method that allows to determine the basic hydrodynamic characteristics of gas-liquid systems produced by forcing air through a porous glass filter elements with an air flow of 1.0·10-3 – 1.0·10-1 sm3/(sm2 s) and a different height of the water layer above the bubble generator. Analysis of variance system prepared with distilled water from the purified surfactant (surfactant), found that close to normal size distribution of the bubbles have a fairly wide range of equivalent diameter of 608 microns. Designed collective speed and flow regimes of air bubbles, pop in the transition region changes Reynolds numbers (1 <Re <100). The proposed method of estimating the hydrodynamic characteristics of gas-liquid systems will be useful in the study of physical and chemical laws of flotation extraction of particles using a surfactant, and the results are used to determine the hydrodynamic field bubble, the parameters of which often depends on the efficiency of the flotation nonchemical water purification from suspended particles.
The theory of electrical conduction is developed in the framework of the “bottom – up” approach without invoking the concept of an external electric field generated by a potential difference applied to the conductor. Within the concept of «bottom – up» approach of modern nanoelectronics the diffusion-drift model of a current on the basis of the Boltzmann transport equation is described. There are also discussed the role of the external electric field beyond the linear response regime, field-effect transistor and saturation current, the role of conductor charging, the point and extended models of a conductor, the role of contacts, the model of p-n junctions, the generation of a current in a conductor with asymmetric contacts.
In summary, we conclude, that when a band structure is given, number of modes can be evaluated and, if a model for the mean-free-pass for backscattering can be chosen, then the near-equilibrium transport coefficients can be evaluated. Next, the new generalized Ohm’s law was formulated and used which provides a quite different view of resistivity in terms of the number of modes per unit area and the mean-free-path. Finally, the transport model given is equally well applied either to nanoresistors or as well to micro- and macroconductors made of any kind of materials.
It is presented an effective relativistic approach to the description of the energy and spectral characteristics of the pion atoms, based on the Klein-Gordon-Fock equation, model of optimized optical strong pion-nucleon interaction potential and method of the relativistic many-particle perturbation theory with the “0” Hamiltonian of the Dirac- Breit -Kohn-Sham approximation ( approximation to the formal precision QED perturbation theory) and correct accounting for the relativistic, radiation QED effects, the finite size nuclear effects plus the nuclear quadrupole deformation correction and electron shielding effect (electromagnetic unit). The bare interaction potential in the system is represented as the sum of the optical strong π–– N interaction potential, relativistic Coulomb potential describing the interaction of the pion with the nucleus as amended by the Breit-Rosenthal-Crawford-Schawlow correction on the final size of a nucleus, generalized radiation potential, taking into account the main QED effect of vacuum polarization, etc., and the self-consistent potential of the surviving electron shells. For a number of heavy π–– А, including, 181 Ta, 197Au,203Tl, 208Pb, 209Bi, etc there are presented the values of the shifts and widths for the 4f, 3d levels due to the strong π–– N interaction, including the corrections, ‘directly related to the effect of the nuclear quadrupole deformation. For a number of π–– А the data on the shifts and widths of the energy levels in a spectrum are presented for the first time.
Non-equilibrium Green’s functions method is applied to model transport problems for 1D and 2D uniform conductors using the nearest neighbor orthogonal tight-binding approximation in the frame of the «bottom – up» approach of modern nanoelectronics.
First of all we discuss the construction of the contact matrices of self-energies. The basic idea is that infinitely long conductor described by the Hamiltonian [H] is replaced by a conductor of the finite length described by the matrix [H + Σ1 + Σ2] with the open boundary conditions at the ends meaning “good” contacts, which do not create the reflected streams at its ends. Further we discuss 1D ballistic conductor, a 1D conductor with a single scattering center, then 2D conductor is modeling and explanation is given to the steplike dependence of the transmission coefficients over the energy, and finally there is given the representation of 2D/3D conductor in the form of parallel 1D conductors, which is not only physically correct but also extremely useful in interpreting experimental data.
In summary the physical adequacy of the Huckel approach is stated in the framework of the method of nonequilibrium Green’s functions.
Sets out the elements of a gauge-invariant method of relativistic calculations within the relativistic-relativistic perturbation theory characteristics three-quasiparticle atomic states, in particular, states that correspond to the so-called dielectrons satellites of spectral lines of multiply charged ions complex. Proposed to develop an effective solution to the problem of the computational scheme for calculating matrix elementsments corresponding perturbation operator for the N-quasiparticle states in the relativistic orbitals gaugeinvariant QED TV Single- quasiparticle approach and its use in calculations of the spectra dielectronic satellites complex atomic systems, and multiply charged ions. In order to construct the optimized nonempirical single- quasiparticle approximation of QED PT for mulkti-electron three-quasiparticle atomic system it is used an relativistic energy approach. The problem is reduced to the formulation of a gauge-invariant principle of determining the electron density of the core in the atomic system (or zero-order Hamiltonian, or in the particular case, the specific parameters of the model-building with several particles of the core without the use of empirical data). Seeking the principle of optimization is reduced to minimization of the energy functional, representing the contribution of the QED PT fourth-order polarization diagrams (second-order atomic PT).
The aim is to develop effective from the computational point of view of methods to describe the energy and spectral properties of Rydberg atoms in the framework of a quantum defect, the device implemented in the corresponding relativistic multiparticle perturbation theory. In the modern theory there is an urgent need to develop new, high-precision, of course, and ab initio relativistic gaugeinvariant theories of radiative transitions in the spectra of Rydberg atoms, multiply charged ions, but with mandatory use of the unique physical characteristics of these systems. In developing our version of the method of the relativistic model potential at the potential of the core is to realize the potential of the relativistic quantum defect approach Dplyus effective exchange-correlation interaction potential “foreign particle-frame.” Contained in the potential of the model parameter is defined in the framework of QED minimization procedure is gauge-violating contribution to the width of the radiation level in the generation of optimized bases relativistic wave functions (ab initio detection circuit parameter).
In the paper we give a review of a new generalized energy approach (Gell-Mann and Low S-matrix formalism) combined with the relativistic multi-quasiparticle (QP) perturbation theory (PT) with the Dirac-Kohn-Sham zeroth approximation and accounting for the exchange-correlation, relativistic corrections to studying autoionization resonances in the complex atomic spectra. As application, we list the energies and widths of the number of the Rydberg resonances in helium. There are presented the results of comparison of our theory data for some helium autoionization resonances with the available experimental data and those results of other theories, including, method of complex rotation by Ho, algebraic approach by Wakid-Callaway, diagonalization method by Senashenko-Wague etc. Besides, we present new data on the energies of the configurations 1s5s, 1s5p, 1s5d, 1s5f, 1s5g terms in the spectrum of the ion Kr XXXV, as well as the corresponding values of the lifetimes of these states, calculated on the basis of the relativistic energy approach.
Increasing agricultural production contributes to the rise in amount of wastes being both the result of residue formation under crop harvesting and the co-product of keeping farm animals. In order to use the mentioned wastes for obtaining alternative fuel through anaerobic digestion in biogas plants, it is necessary to estimate the volume of generated organic waste and to plan a biogas production in farms within various districts of the Odessa oblast. The main factor for elaboration of a logical system meeting the formulated requirements is the necessity to systematize the initial and calculated data and to obtain the calculation results. The paper aims at development of a cross-platform geographic information system, which makes it possible to perform systematization of the statistical data, calculation of the agricultural waste amount formed in various districts of the Odessa oblast; regulation of the received data and their visualization as a graphic content. A geographic information system, which contains the following structural elements, has been developed:
1) an interactive contoured map for the districts of the Odessa oblast; 2) a database containing both cartographic and attributive information on the biogas resources in the districts of the Odessa oblast; 3) a GIS application to process and visualize the geodatabase on the computer display.
GIS as a technology, which combines a database function, a spatial analysis and a high-grade visualization, can be used for numerous problems ranging from the initial data analysis to forecasting the outcomes of the specific environmental impact methods. Visualization of the results of data analysis as a graphical content provides an opportunity for the end user to evaluate the obtained information in a visual way, to plan the current activities or make a decision on the generation of further development strategy with regard to resource management.
The article deals with noise-proof, highly sensitive and accurate signal processing algorithms in the up-per-air radiosonde ranging stages, telemetry signal isolation, calculation of meteorological parameters. The effectiveness of the proposed algorithms performed by computational experiment for coherent and incoherent detector. The experiment was conducted using a computer. Both used the detector output MAV-PLL demodulator in order to obtain a reliable algorithm for both detectors used identical input. Science Experiment results show that the coherent detector signal probe identifies clearly better at low signal to noise ratio. At -8 dB gives a false signal value of the probe. A similar pattern was repeated at lower values of signal-to-noise -11 dB. During the experiments, there has been a steady gap detection threshold of the coherent detector 3-4 dB.
