A new Test of Filterability has been developed. Measurements carried out with different types of wines indicate that the new filterability index is a useful tool for understanding and predicting the propensity to fouling of treated or untreated wines, e.g. with or without enzyme addition. The measurement method used in the Test of Filterability, requires only one type of membrane for all types of wine, and uses the same equipment as the traditional Fouling Index. Numerous trials have demonstrated that the filtration of wines is governed by standard blocking law. The definition of the new Test of Filterability, based on this filtration law, is proposed. The choice of membrane and the selection of the optimal pore size were based on the results of the experiments. Current methods used for the determination of fouling properties in wine filtration have been developed for the membrane filtration of small quantities of suspended matter. Enzyme treatment is a process often used in wine clarification. The new Test of Filterability indicates the best conditions for the filtration of all types of wines. The test is easy to implement and has been validated with various wines. This new Test of Filterability is an important tool for winemakers as it constitutes a simplified test of a wine's filterability. The new test may also be used to determine the filtration process that is best adapted to each wine while reducing the number of operations. The same approach may be adopted for the filtration of other liquids.

Definition Of

An important quantitative characteristic of symbolic sequence (texts, strings) is complexity, which reflects at the intuitive level the degree of their "non-randomness". A.N. Kolmogorov formulated the most general definition of complexity. He proposed measuring the complexity of an object (symbolic sequence) by the length of the shortest descriptions by which this object can be uniquely reconstructed. Since there is no program guaranteed to search for the shortest description, in practice, various algorithmic approximations considered in this paper are used for this purpose. Along with definitions of complexity, suggesting the possibility of reconstruction a sequence from its "description", a number of measures are considered that do not imply such restoration. They are based on the calculation of some quantitative characteristics. Of interest is not only a quantitative assessment of complexity, but also the identification and classification of structural regularities that determine its specific value. In one form or another, they are expressed in the demonstration of repetition in the broadest sense. The considered measures of complexity are conventionally divided into statistical ones that take into account the frequency of occurrence of symbols or short “words” in the text, “dictionary” ones that estimate the number of different “subwords” and “structural” ones based on the identification of long repeating fragments of text and the determination of relationships between them. Most of the methods are designed for sequences of an arbitrary linguistic nature. The special attention paid to DNA sequences, reflected in the title of the article, is due to the importance of the object, manifestations of repetition of different types, and numerous examples of using the concept of complexity in solving problems of classification and evolution of various biological objects. Local structural features found in the sliding window mode in DNA sequences are of considerable interest, since zones of low complexity in the genomes of various organisms are often associated with the regulation of basic genetic processes.

Abstract. The phase after the determination of the landslide area in landslide susceptibility studies is the selection of methods and parameters to be used. Approximately 1500 randomly selected publications show that it is necessary to select a parameter based on the area. Research has shown that the parameter of slope is greatly preferred. There is nearly consensus of opinion among researchers regarding the use of the parameter. The research included the definition of slope made by different researchers, the advantages and disadvantages of the use of the parameter, different classifications that are used, the formation intervals of landslides, their use together with other parameters, and its effect on the formation of landslides. Classifications were studied based on the slope values at which landslides. Generally, automatic slope classifications are used in the preparation of landslide maps. There isn’t standard in parameter maps. Therefore, there isn’t class range that is referenced when preparing slope maps. In this study, preferred class ranges and slope values where landslides occur were determined in the literature. 40 landslides area has been selected in Turkey. These were evaluated in the slope classes determined according to the literature. The results compared with the literature were found to be compatible.

Knowledge of the laws of manipulation, analysis of the mechanism of this phenomenon in conjunction with a proper understanding of the state and demands of society can help any political leader in the struggle for power and the promotion of their own political interests. The key to successful manipulation in political discourse is the realization of the paramount importance of the ultimate goal. Depending on it, the strategy, tactics and methods of manipulation will be chosen. Careful selection of linguistictools will help to keep manipulative processes out of the realm of awareness and ensure their effective effectiveness. Manipulation is understood as hidden coercion, programming of thoughts, intentions, feelings, and so on. The main purpose of manipulation is to create a profitable policy of the world in the minds of potential voters and reduce the ability of recipients to think critically, creating the illusion of free choice and more. Language manipulation should be understood as the purposeful use of thepeculiarities of language use, which contributes to the emergence in the minds of recipients of illusions and delusions that motivate him to act in a way that is beneficial to the manipulator. It should be noted that any successfully completed communication in which the speaker does not express his intentions openly, is a successful act of language manipulation. The very phenomenon of manipulation in political discourse is given a special place, as it can cause long-term consequences and have a strongeffect on society. Obviously, further study of the phenomenon of manipulation in the linguopragmatic aspect is needed, describing not only the different types of manipulative influence, but also how they contribute to the success / failure of policies and for what reason one or another effect is achieved. The main approaches to the definition of "speech manipulation" and highlights and systematizes the dominant approaches inthe Ukrainian scientific linguistic tradition to it, namely: narrow and broad approaches, and at the same time considers scientific linguistic approaches that consider speech manipulation from different angles. . The main focus is on different classification approaches to this issue, as well as the main criteria for classifying types of speech manipulation (by the nature of the interaction of the addressee and the addressee; by the criterion of awareness of speech actions of the addressee and the addressee; by theorientation of the addressee; by the nature of information transformations) . Modern approaches to their delimitation are highlighted. At the same time, the levels at which speech manipulation is performed (phonetic, lexical and grammatical) are considered.

This article is dedicated to the theoretical understanding of the problem of ambiguity of the concept of “legal policy” as a complicated phenomenon that has a substantial number of attributes, which connect it with multiple occurrences within the legal sphere of social life and outside it; as well as overcoming such ambiguity through analyzing the diversity of characteristics of legal policy presented in the definitions of modern authors , and formation of the unified definition on their basis that would serve as methodological framework for the research of legal policy in all branches of juridical science. Research methodology includes the general scientific methods, such as analysis, synthesis, comparison, generalization, classification, and systemic approach. The author analyzes different points of view of the Russian scholars on formation of the concept of legal policy; describes their specific features; makes an attempt of their systematization. The conclusion is made on the presence of two different types of approaches towards determination of the content of legal policy. The author highlights most substantial characteristic suitable for both approaches, and offers an original version of a unified definition of legal policy of the state.

Communication among scientists must be clear and concise to avoid ambiguity and misinterpretations. The selection of words must be based on accepted definitions. The fields of biomechanics, muscle physiology, and exercise science have had a particularly difficult time with terminology, arising from the complexity of muscle contractions and by the use of inappropriate terminology by scientists. The dictionary definition of the verb “contract,” specifically for the case of muscle, is “to undergo an increase in tension, or force, and become shorter.” Under all circumstances, an activated muscle generates force, but an activated muscle generating force does not invariably shorten! During the 1920s and 1930s, investigators recognized that the interaction between the force generated by the muscle and the load on the muscle results in either shortening, no length change (isometric), or lengthening of the muscle. The recognition that muscles perform three different types of “contractions” required that contraction be redefined as “to undergo activation and generate force.” Modifiers of contraction are then needed to clarify the lack of movement or the directionality of movement. Despite the contradiction, for 75 years the lack of movement has been termed an “isometric contraction.” The directionality of the movement is then best described by the adjectives “shortening” and “lengthening.” The definitions of “concentric” as “having the same center” and of “eccentric” as “not having the same center” are consistent with hypertrophy, or remodeling of the heart muscle, but are inappropriate to describe the contractions of skeletal muscles.

The authors have been researching the effect of polyharmonic currents (complex waveform current) on the characteristics of different types of radiators for a few years. These researches have shown an increase in the energy efficiency of installations with dark and light radiators and the ability to control the harmonic composition of radiation. It is important considering the need to harmonize the frequency characteristics of a radiator with the frequency response of an energy absorbing surface. The object of experimental research are flexible heating tape and installations with dark radiators and their joint operation modes when powered by complex waveform current from a common power source. The purpose of the work is the definition of characteristics of the flexible heating tape and dark infrared radiators when changing the amplitude and frequency of the supply voltage to develop recommendations for the selection of effective modes.

This technical report is a general introduction to organic photochromism. The definition of photochromism (PC) is given together with that of words with the ending "chromism", such as thermo-, electro-, piezo-, and tribochromism. Important concepts such as two-photon, gated, dual-mode PC and chirochromism are illustrated. The concept of fatigue (chemical degradation) and the determination of the main photochromic parameters (number of cycles, cyclability, half-life), and the spectrokinetic and mechanistic aspects are discussed. The main families of PC (organic compounds and biological receptors) are illustrated with chemical formulae, and the different types of reactions involved in the photochromic processes (pericyclic reactions, E/Z isomerization, group transfer, etc.) are listed. Some examples of applications to "optical power limiting" substances, photoresponsive materials, and photoswitchable biomaterials are considered.
