In this article we consider the most popular methods for evaluating the degree of olfactory disorders. The purpose of our paper is an analytical review of olfactometry of methods and tools to determine their potential and the diagnostic value of the detection of respiratory-olfactory disorders (blocking of odorants getting into areas of the nasal mucosa, containing olfactory receptors). Purpusful study of olfactory function allows to determine the criteria for the diagnosis of local destruction of various parts of the analyze. Various methods and devices (olfactometers) are used to diagnose olfactory analyzer, but they all have a number of drawbacks: the long duration of the study, the use of objective evidence of the subjects, the use of olfactory substances that affect the end of the threefold nerve, determination of olfactory dysfunction or only quantitatively or only qualitatively. Most of the methods for evaluating of olfactory disorders have a wide range of uses for the diagnosis of various diseases as well, including mental disorders, brain damage, and nervous system. However, within our problem, olfactory dysfunction is necessary to consider in connection with the problem of the air passage in the human olfactory system. Therefore, it is necessary to develop a highly specialized method of assessing olfactory respiratory disorders, which would have a high degree of objectivity for use in clinical practice of otolaryngologists. Thus, in the perspective of further research it seems necessary to develop a method of assessment of olfactory function on the basis of respiratory parameters derived from rinomanometry research that will improve the objectivity of conducted researches.

Measuring the characteristics of process fluids allows us to evaluate their quality, biological tissues – to differentiate healthy tissues and tissues with pathologies. Measuring the characteristics of process fluids allows us to evaluate their quality, biological tissues – to differentiate healthy tissues and tissues with pathologies. One of the complex acoustic parameters is the impedance, which allows one to fully evaluate the characteristics of viscoelastic media. Most of impedance methods of measurements require using two or more reference media and the availability of calibrated acoustic transducers. The aim of this work ware introduced a methods and construction for the experimental evaluation of the longitudinal and shear impedance of viscoelastic media based on measuring the parameters of the amplitude-frequency characteristics and calculating the elements of the electric circuit for replacing the piezoelectric element which vibrating in the test medium.The paper introduces a methods and construction of the experimental evaluation of the impedances of viscoelastic media. The suggested methods is allowed measuring longitudinal and shear impedances and determining velocities of longitudinal and transverse ultrasonic waves and the values of the elastic moduli of viscoelastic media, including in various aggregate states. The technique is fairly simple to implement and can be reproduced using simple laboratory equipment.The obtained values of the acoustic impedances of the investigated media are in satisfactory agreement with their reference data. In contrast to the known methods for determining the acoustic impedance, the developed technique allows us to estimate with sufficient accuracy the parameter of the shear impedance of viscoelastic media that is difficult to measure at the frequencies of the megahertz range, which determines the shear modulus of the material and characterizes its resistance to shear deformations. The results of the implementation of the developed technique for the estimation of acoustic parameters for a number of media with zero shear elasticity (alcohol, acetone) and viscoelastic media (glycerin, architectural clay, silicone sealant and glue МР-55 before and after polymerization) are presented.

A model of deformation of an inhomogeneity in terms of static ultrasound elastography is described. The influence of the parameters of the inhomogeneity and the static pressure on the deformation process was investigated, and the possibility to quantify shear modulus values of the elastic inhomogeneity is justified.

The purpose of our article is to investigate the process of approximation of Ukrainian environmental legislation to EU law. The range of issues that Ukraine has reformed in the field of environment has been investigated. The state of compliance of Ukrainian environmental legislation with the commitments under the EU-Ukraine Association Agreement was revealed. The problems of further effective application in practice of the adopted regulatory legal acts, strategies and action plans were disclosed. Particular attention was paid to water legislation and legislation in the field of waste management. The current state of the sphere of solid waste management in Ukraine was revealed. The state of adaptation of Ukrainian water legislation to the requirements of the European Union law has been investigated. Ways to improve Ukraine's environmental policy on waste and water policy based on European experience were substantiated. The methods of comparative law, statistical, analytical and logical analysis were used.  Keywords: EU Environmental policy, environmental law, EU water policy, EU waste policy, Ukrainian environmental legislation
