Abstract Potato cultivars are classified into maturity groups according to the length of the vegetation period required to produce a harvestable product. Although accurate classification of potato cultivars to a specific maturity group is of great practical importance, there is no standard method to characterize the maturity type of potato cultivars. In this work, the method of evaluation of vegetation period routinely used at IHAR-PIB, Młochów Research Center is described.

A new method has been elaborated to estimate the length of the vegetation period of new maize hybrids. According to this method, the length of the vegetation period is expressed by the FAO number, calculated from the following traits: 1. 50% silking 2. Grain moisture when the average grain moisture of maturity group standards is 25% 3. Grain moisture when the average grain moisture of maturity group standards is 20% 4. Grain moisture at harvest. The standards of the neighbouring maturity groups are also included in each experiment.The results obtained with this method were compared to the heat unit (GDD) method and to other methods of calculating FAO numbers. The new method has several advantages over previous techniques based on moisture content alone: the fluctuation of the estimated FAO number over locations and years decreased, as did the significant differences between the calculated FAO numbers; the reliability and precision of the new FAO number is less dependent on the date of harvest (moisture content); and the FAO numbers calculated with the new method are in the closest correlation with the heat unit estimates.

This work is devoted to the speech impact of advertising texts, in other words, the language of advertising, the purpose of which is to attract the attention of a potential consumer by making the message as memorable and unusual as possible, lively and catchy, colorful and attractive to a potential listener / buyer. The significance of the work lies in the fact that the author, in the process of analyzing the basic structural elements of the advertising message (slogan and main body), determines the main speech techniques for the influence of advertising texts: expressive means, including metaphors, epithets metonymy, speech turns, paths, various grammatical forms and other forms of influence: nominative, one-part, verb sentences, comparative and superlative adjectives, rhymes, imperative verbs, adverbs, lexical repetition. On specific examples of advertising slogans, evidence is given that the above speech means contribute to increased demand for the advertised product or service. During the study, the author confirms the hypothesis put forward at the beginning of the study: if you skillfully use speech exposure, i.e. to choose words whose harmonious combination lays in the subconscious of a person the information transmitted to him by the manufacturer through high-quality advertising, then such an advertising text can become the key to the success of trade. The work is of great practical importance: the material presented in it can be used by students to improve the culture of speech, improve stylistically differentiated speech, as well as school teachers as methodological material in the Russian language when studying the section «Vocabulary», «Stylistics».

One of the urgent problems of modern dermatology, which are of deep scientific interest and are of extremely great practical importance, is the complex and controversial issue of the etiology of eczema. However, despite the colossal literature, despite a number of detailed experimental studies, the main and deep contradictions of representatives of the main dermatological schools on the nature of eczema remain unresolved.

If in any other branch of medicine the precise nomenclature and classification of different forms of the same kind of disease are undoubtedly of great theoretical and practical importance, the more interesting is a scientifically sound nomenclature and a reasonable classification for the various forms of tbc in general and tbc of the lungs in particular.

Skin temperature depends mainly on the amount of incoming blood and is of great practical importance. In limb artery embolism the skin temperature reveals a large difference on the healthy and diseased limb. In doubtful cases this symptom allows a diagnosis to be made after 1-2 hours and a timely operation to be undertaken.

The experimental use of “geologic radar” to explore through coal from mined passages underground has already been reported elsewhere (Cook, 1973, 1974). Low‐resolution borehole radar work in salt, a much more favorable medium, has also been reported (Holzer et al., 1972). The purpose of this paper is to report the first known results of borehole radar tests in coal. The exploration of coal seams via boreholes from the surface is potentially a technique of great practical importance. The borehole experiment was performed in conjunction with a month‐long program of radar tests in Australian collieries and quarries performed under the sponsorship of the third ICOGEO and supported by several Australian mining and research organizations. A report on that program is expected to appear in the Bulletin of the Australian Society of Exploration Geophysicists some time during 1977.

The topic of human attitudes about computers has been dealt with extensively in both the academic and popular literature, but it remains an issue of importance. The continued relevance was well illustrated by the Soviet chess grandmaster, Karpov, who recently remarked that he was not afraid to lose a chess game to a computer, but that people who worked with such computers could lose their soul to the machines (Hooper, 1990). The beliefs which people hold toward computers will affect their computer interaction and their willingness to adapt to automated systems: therefore the issue is of great practical importance. This paper reports on a replication of an early IBM study with the intent of assessing contemporary attitudes towards computers and the changes in attitudes over the last 25 years.

Irrigated lands of Bukhara, Samarkand and Navoi regions are located in the Zarafshan river oasis and are called geosystems. Assessment of the reclamation state of geosystems of the region has been carried out in the area of classification and mapping for the effective use of land. When classifying a research object, it is much easier to identify, evaluate and apply reclamation measures. In the classification of landscapes, they are grouped in a certain order and there is an opportunity to apply such reclamation measures. So far, the basin-level classification of the Zarafshan river oasis and geosystems has not been carried out. In the scientific paper, landscapes were analysed as a form of geosystem. The geosystems of the region were grouped and summarized for the performance of the reclamation geographical assessment based on water and salt parameters. The classification of the object of study using GIS is of great scientific and practical importance. An analysis of the origin, structure, development and other features of an object when it is classified will determine the scientific significance of the case. Geosystems were isolated using the forms depicted on the relief plastic card in the scientific paper. Measures have been developed to improve the reclamation state of existing geosystems. They reached scientifically sound conclusions.

This review focuses on the enzymatic breakdown of chitin, taking into account the latest scientific reports on the activity of lytic polysaccharide monooxygenase (LPMO). Chitin is a natural, abundant polysaccharide of great practical importance in the environment. However, the insolubility in water and the tightly packed crystalline structure of chitin pose a serious obstacle to enzymatic degradation. This substrate can be converted into soluble sugars by the action of glycosidic hydrolases (GH), also known as chitinases. LPMO could prove to be helpful in enzymatic processes that increase the rate of chitin depolymerisation by improving the availability of substrates for chitinases. The unique action of LPMO is based on the ability to catalyse the oxidative cleavage of glycosidic chains present in complex, resistant crystal networks of chitin, and this cleavage facilitates the subsequent action of glycolytic hydrolases.
