The classification of municipal solid waste (waste from the residential sector, municipal infrastructure and municipal agencies). General waste stream consists of easily-decomposed organic waste, bulky waste, potentially recyclable material resources (waste collection container) and hazardous waste, which can be used as secondary material resources.
The article deals with the issues of used power sources. The recycling of e-waste as one of the ways to solve the environmental pollution problem of used household power sources is considered. The methodical approach of the evaluation value of profit loss because of the absence utilization of primary batteries, which based on the definition of abstract damage caused by getting into the environment used batteries, is suggested.
European Union (EU) normative – legal framework in the field of waste management, methods and tools as well as the general principles and waste management schemes in the EU and Ukraine environmental policy problems in the field of waste management to policy are considered.
The modern state and economic consequences of climate change are assessed. The economic aspects of the stabilization of greenhouse gas concentrations in the atmosphere at a relatively safe level are investigated. Particular attention is given to the effects of climate change in Ukraine and analyzing the degree of exposure to these changes in different sectors of the economy.
Assessment model of agroclimatic resources made by A.M. Polevoy for the formation of crop productivity was adapted and modified to the spring barley. The parameters of the model and influence of agro-climatic conditions to the crop productivity are defined. Assessment of agroclimatic resources in the physiographic zones of the Odesa province for the period from 1980 to 2010 and the agroecological productivity categories (PY, MPY, IPY, YP) in relation to the spring barley is presented.
An analysis calculating the potential yield of winter wheat in the south of Ukraine in terms of mean growing season based agrochemical characteristics of the main types of soil zone. According to our calculations, the potential yield of winter wheat on soils of the south of Ukraine may take up to 46 kg/ha.
The changes of agroclimatic conditions of sunflowers growth and development in different climate change scenarios were discussed. The photosynthetic productivity, sunflower seeds yield fluctuations due to possible climate change in the eastern forest-steppe zone of Ukraine were evaluated using the model of sunflower crops productivity.
On example of Tarutino territory in Odessa has been implemented method of detailed assessment of agro-climatic resources in a limited area with heterogeneous underlying surface considering microclimate. Allocated microclimatic regions that differ in the resources of light, heat and moisture and freeze and frost conditions, due to the different elements of relief. Keywords: agro-climatic resources, types of underlying surface, the elements of relief, microclimate.
It is considered the agro-climatic conditions changing of grape growing in the Northern Black Sea. The estimation of wine grapes vegetative phase’s dates offset in the implementation of climate scenarios was done. Based on a model developed by the authors the yield estimated due to potential climate change.
In the article considers the scientific and methodological approaches to the improvement of parameters formulas of maximum runoff of rain and floods of spring floods.
It was conducted a synthesis and analysis in waters Kakhovka reservoir to investigate the impact on them of climate change over the past decade, on the basis of the actual meteorological data.
Characteristics of aridity (index SPEI) and characteristics of flow during the summer-autumn low water period on the example Savranka River are estimated. Using multiple linear regression model with stepwise selection of predictors links between established of low flow and drought are established.
To regulation design characteristics of the maximum spring flood runoff in the basin of the Southern Buh River was used structure, which is based on isochronous channel theory.
The basic characteristic of the module taken over land in flow, which in turn depends on the time of uneven slope coefficients tide, its duration, the form factors of trans formation hydrograph sand channel-floodplain regulation.
It was considered the features of physical properties of silty soils, which are forming the area of different facies: silty, rakusha, detritus of rakusha, dresva on-the-spot shallow sea-bottom and allowing to trace hydrodynamic situations, which are recreating 40-50-years-old stable circulations in the Kerch bay.
Results of adaptation, calibration and validation of the hydrodynamic model based on the open-source software Delft3D-FLOW to the conditions of the Tyligulskyi estuary are given. It is shown that the model correctly describes the variability of the thermohaline structure of waters in the estuary during spring-summer warming period with the use of field data for the 2010 and 2012. Between May and August 2010, a firmly established seasonal thermocline lasted throughout the computational period; in 2012, there was a significant weakening of the thermocline in May and June and to the beginning of August a quasi-homogeneous vertical thermal structure of waters was formed. A conclusion is made about the possibility of using the model for applications related to the development of the hydro-ecological management plan of the estuary.
Non-equilibrium Green’s functions method in matrix presentation is given with application to transport of electrons in quantum regime.
Within the refined 3-modal model of kinetic processes there is examined a photokinetics of the energy exchange in a mixture of CO2-N2-H2O atmospheric gases while passing powerful laser CO2 radiation through an atmosphere.
Within the chaos-geometric approach there are obtained improved data on the analysis and forecasting chaotic fluctuations in the time series of concentrations of nitrogen dioxide and sulfur dioxide in the atmosphere of the Gdansk region.
We use Bateman algorithm [1] to set exact solution of the linearized equations of motion for perturbation in vertical granular chain under the confinement. It is shown the wave dynamics is strongly influenced by boundary conditions and constitutive relations.
Found, that at interaction of acid chlorides of ortho-, peri-, cis- dicarboxylic acids with primary amines are formed appropriate isoimides. A series isoimides of 2,3-dichlorobut-2-enedioic acid was synthesized.
In article abilities of nonlinear processing signals of hydrometeorology data on functional rows and polynoms of Volterra base are researched.
Development of the special program interface is presented for operative work with water objects on administrative-territorial and pool principles and receipts of quantitative descriptions of object.
