The specific conditions of the protected ground, the almost constant tomato culture without substitution of the substrate, the elevated temperature and humidity lead to the accumulation of a large number of pathogens of bacterial diseases, which limit the increase in yield of this crop. The aim of the work was to characterize the symptoms, determine the etiology of wet rot of tomatoes for growing in protected ground and propose measures to control the pathogen. The study was conducted by standard microbiological and phytopathological methods. The pathogenic properties of the isolates were studied on vegetative tomato plants using a suspension of bacterial cells with a titer of 107 CFU/ml. It was established that the defeat of tomato plants with soft bacterial rot in closed ground conditions prevails in the second half of the growing season. The development of the disease was 30‒34% for a prevalence of 45%. Diseases of tomato plants in greenhouses in the Kiev region of Ukraine are of bacterial origin, caused by the soft rot pathogen P. carotovorum subsp. carotovorum. Characteristic symptoms of wet tomato rot are discoloration, chlorosis and leaf necrosis, void stems, the appearance of depressed water-saturated areas in the stalk, accompanied by decay of the fetus. Effective control measures can be preventive and agricultural measures

A log-and-earth fortress on Zayachy island in the Neva River mouth was erected in 1703 by direction of Peter the Great. The building works took a short period from early May to late August. The construction of the stone fortress started in 1706. In 2017 and 2019, in the course of archaeological excavations carried out by IHMC RAS, a unique cultural layer with remains of the first log-and-earth fortress was discovered on the territory of the Menshikov bastion. Among the most important finds there are 18 coins issued by Peter I, including 14 wire kopecks, three copper quarter-kopeck pieces, and one copper half-kopeck coin. Two more coins with denomination of 1/6 öre were issued by Charles Х of Sweden (fig. 1; table). This numismatic collection is a reliable dating material, allowing to identify the constructions found in the cultural layer as the first log- and-earth fortress of Peter the Great, that became the historical core of Saint Petersburg. Worthy of note is the presence in the collection of a number of coins minted with dies made with the same punches, and the absence of coins minted in 1703. The presence of Swedish coins may be indica- tive of the participation in the construction works of captive Swedish soldiers, who could have lost the coins. At the same time it cannot be excluded that these coins were brought to Zayachy island with earth from Nyenschanz, which was used as a source of building materials.
OLDEST SEALS OF CENTRAL ASIA (TYPOLOGY, MATERIAL, MANUFACTURING TECHNOLOGY)
Authors:   Institute for the History of Material Culture RAS, KIRCHO L.
Published: December 2020

The paper deals with systematization of the oldest Central Asian seals that were found at the late Middle Eneolithic — Early Bronze Age settlements of South Turkmenistan. Stone and terracotta flat «seals-amulets» (with a hole in the upper part — fig. 1, 4–13) are characteristic of the Late Eneolithic (Namazga III period, ca. 3150–2800/2700 BC). Images on the front sides of these objects are made by incised lines and/or pyramidal depressions forming cruciform «stepped» patterns. Such «seals-amulets» are known exclusively from Central Asian sites. Flat «seals-buttons» (with two holes in the center) made of clay and bone appear at the very end of the Late Eneolithic (ca. 2800s BC). As is evidenced by the stratigraphy of Altyn-depe, the stone seals of this type are mainly characteristic of the Early Bronze Age (Namazga IV period, ca. 2800/2700–2400/2300 BC). Images on the front sides of «seals-buttons» are made by both incising/engraving (fig. 1, 1–3; 3, 3, 5, 10, 12, 14, 15, 23) and shallow spot drilling (fig. 2, 4, 6–9, 21, 22). «Seals-stamps» (with a suspension eye on the rear side) of terracotta and copper date from the beginning of Early Bronze Age. They bear patterns of drawn lines (fig. 2, 10) or lines combining with circles made by a hollow drill (fig. 2, 11, 13). However, judging by the imprints (fig. 3, 2, 4, 7, 9), the earliest «seals-stamps» were manufactured as early as the end of the Late Eneolithic. Metal «seals- stamps» with high embossed images made in the lost-mould casting technique appear at the very end of the Early Bronze Age (fig. 2, 1) and are characteristic of the Midle Bronze Age (Namazga V period, ca. 2350–2000/1900s BC).

The paper is devoted to the analysis of a series of Middle Bronze Age burials from the barrow cemeteries of Veselyi I, Chaltyrskiy XI, Glubokaya II and Molokanovskiy III in the Lower Don region. All of them present a hitherto unknown type of demembration which involves a complete of partial displacement of bones “in blocks”, i. e. in anatomical articulation. Judging by both their inventory and ritual details, the burials in question belong to the late stage of the Catacomb culture (late stage of the Donets culture, Bakhmur variant, and the Manych culture). The displacement of bones “in blocks” (and penetration into the grave) took place during the first year after the funeral. There is a number of hypotheses that attempt to explain the appearance of demembration in ritual practices of ancient people. The burial contexts described in this paper support the hypothesis ac- cording to which demembration served as a method of rendering the dear harmless.

The issues of energy efficiency assessment for inland navigation vessels and focus on the need to implement different approaches in this context in relation to single vessels against pushers with heavy convoys are considered. This is due to transportation technologies, which have a number of significant differences when pushing a heavy caravan. The analyses were made for the data of systematic testing of ships and the values of energy efficiency indicators obtained for them according to the methodology applied by IMO for ships in international maritime shipping. Fluctuations in water levels on inland waterways and on river sections, in particular, especially when moving pushers with caravans of barges, have a significant impact on the performance of the hydrodynamic propulsive complex. Using the example of the data from the Danube river gauging stations, the assuring enough depth both when performing one voyage at different sections of movement, and during a calendar year were considered. The ratios of the fairway depth and the draft of the vessel are determined, which are boundary for a decrease in the speed of movement in connection with a change in resistance with a tangible negative effect of shallow water. In this regard, issues of increasing fuel consumption in shallow water areas and related factors affecting energy efficiency are also considered. At the same time, the interrelation of energy efficiency and eco-friendliness dictates the use of integrated approaches not only from the standpoint of quantitative indicators of fuel consumption, but also from the standpoint of the use of modern technologies for cleaning exhaust gases. The factors contributing to the development of energy efficiency management are considered as separate categories. These include the work of the River Information Services (RIS), the training of river boatmasters and the instability factors in the shipping and bunker markets. The conclusions about the inseparability of the considered factors, as well as the need for their further comprehensive consideration in order to create a common algorithm for managing energy efficiency in the inland navigation were made.

he article deals with steering gears, used on marine and river ships, namely with ram-type steering gears. Article topicality due to the fact that ship controllability and sailing safety depends of steering gears reliability. Reliability could be increased through the refinement of processes, which took place during the perception and transfer of load. Process of lateral force perception by plungers and guide beams is studied theoretically. It is shown that perception depends of gap size between plunger and sleeve and could pass in one, two or three stages. Those stages are characterized changing in the loading process plungers fixing conditions, and respectively plunger lateral load proposed to determinate by three design schemes. Received expressions for calculation ultimate gaps of «plunger-sleeve» pare landing, that gives the limits of application each of three design schemes. Ratios for determination load of plunger and guide beam are received trough consideration their joint deformation for each design schemes. On the example of YOOWON-MITSUBISHI YDFT-335-2 ram-type steering gear is shown that in new gear, where landing gap is minimal and conditioned by tolerances of plunger and sleeve diameters, guide beam can take only 2.0…6.5% of lateral force, which applied to it and plunger from tiller. In steering gear with partially worn out plunger and sleeve in time of rudder feather shifting from diametric plane to board (when α = 5…35º), guide beam could take 4.7…6.8% of lateral force. The source of origin significant loads on plungers in ram-type steering gears is application of sinus-type mechanism for transformation progressive plunger motion to rotating tiller motion. Decreasing lateral loads on plunger through using unloading guide beams, with considering low unloading percent is ineffective. Guide beams availability complicates steering gear construction, increasing number of friction surfaces and trough this complicates steering gear maintenance.

The paper analyzes hydrometeorological phenomena in the port of Chornomorsk. Changes in climatic conditions over the past 5 years have been identified. The most dangerous directions and speeds of winds, waves, which affect the operation of the port, have been determined. Analyzed the precipitation and the frequency of occurrence of various meteorological phenomena (thunderstorms, fogs, blizzards) in recent years. Conclusions were made on the unfavorable conditions of the port. Ensuring the safety of navigation during entry and exit from the port is one of the most pressing problems. Analysis of hydrometeorological conditions helps to reduce the number of accidents that occur due to ships grounding and bulkheads on the berth. Knowing the weather conditions in the port water area, you can ensure the safety of navigation. To compile a statistical analysis of the hydrometeorological characteristics in the port, a study of the logs of meteorological observations for every day over the past 10 years, as well as the cadastres of the seaports of Ukraine was carried out. The result of this analysis is the receipt of unfavorable factors that hinder the operation of the port in normal mode. It was also possible to establish the most unfavorable phenomena that limited the possibility of entering and leaving the port, as well as the months in which these phenomena are possible. Analysis of the parameters of the hydrometeorological situation allows us to conclude that the industrial activity of the port largely depends on the state of the weather and the sea. unfavorable meteorological phenomena reduce the efficiency of work and can pose a threat to the safety of their conduct. Various weather and sea phenomena affect port operations in different ways. The production activity of the port is largely dependent on the state of the weather and the sea, since unfavorable meteorological phenomena reduce the efficiency of work and can threaten the safety of their work. Various weather and sea phenomena affect port operations in different ways.

Published: December 2020

The safety of marine navigation in coastal areas and narrow waters, which account for 80% of total navigational accidents, remains a pressing concern. These circumstances indicate the need to improve traditional and automated methods of passage planning and control of navigation and traffic management processes, based on the assessment of the actual navigation accuracy and navigation safety parameters. According to current industry recommendations, the main parameters of safe navigation are safety depth, safety contour, permissible cross-track limit, and accuracy of position fixing. This study deals with the development of a general practical approach to the calculation of the safety depth, as one of the main safety parameters in the ECDIS system, with an increased focus on those aspects of calculation where navigators tend to make mistakes. Analysis of data obtained during the training on the ECDIS simulator for navigators directly involved in the passage planning process (master, navigation officer) showed systematic mistakes in assessing the route safety, which can lead to ship grounding in real world. At the same time, navigators often do not recognize the danger, misinterpret it or make mistakes when checking the passage plan for safety. The results of the competence assessment showed that 40% of masters and 30% of navigation officers make mistakes in calculating the safety depth. The most common mistakes are the incorrect application of category zones of confidence (CATZOC), miscalculation of the minimum depth on the route, miscalculation of the tide height, tidal window period, the neglect of corrections for increased draught due to roll and pitch. The paper suggests that the UKC (under keel clearance) company policy shall take into account the accuracy of chart information. Furthermore, the research further develops the method of calculating the safety depth, implemented in the software, which makes it possible to systematically assess the safety of a route with multiple legs with heterogeneous parameters.

Principle of action of semiconductor two-collector magnetic transistors and possibility of creation on their basis of electronic compass is covered in the article. Level of automation of marine ships navigation, appearance of the autonomous fully automated ships without a crew, requires presences aboard the ship of device giving out a not visual, but electronic signal about direction of motion. An electronic compass on the basis of magnetic sensor semiconductor elements can decide this task. There is of most interest an electronic compass, a consisting of semiconductor magnetic sensor element, electric signal on the output of which is proportional to the level of the external magnetic field, and electronic chip processing a signal. In this article the example of laboratory construction of such electronic compass is described and his descriptions over are brought. Important, that this electronic device does not have mobile mechanical parts and mechanisms. For the increase of sensitiveness of electronic sensor of the magnetic field application of reflector-absorbers of the magnetic field is offered. Ferrite bars are used in this case. Bars are disposed both-side sensor, parallell to optimum direction of the magnetic field. In the experiments it was succeeded to get the increase of sensitiveness of sensors in 400 times. The reflector-absorbers of the magnetic field also allow to improve correlation signal to noise in 100 times. An electronic compass on the basis of magnetic transistors can be also used and as an element to control the course of marine ship. If a magnetic transistors is set to direction of motion, the change of loading resistances sets the zero of tension between the collectors of magnetic transistor. At deviation of axis from the set direction, tension of one polarity appears between collectors, and in other - opposite. This tension through the system of autopilot can directly control a steering gear and automatically to maintain the set direction of motion of marine ship. Experimental descriptions over of pre-productions models of magnetic transistors and flows diagrams of compasses are brought. An experiments show that on the basis of two-collector magnetic transistors can be created electronic compass not containing mechanically moving details, that sharply promotes his reliability and durability. An electronic compass will become the obligatory attribute of future autonomous ships without a crew. He will be able not only to replace a classic magnetic compass but also to allow to realize the span-new functions of ships control.
IMPACT OF THE CROSS-TRACK ERROR DISTRIBUTION LAW ON SAFE NAVIGATION IN NARROW WATERS
Authors:   National university ", Vorokhobin I.I. ,   Odessa maritime academy",   / Национальный университет ",   Одесская морская академия"
Published: December 2020

The paper indicates that navigation in narrow waters requires navigators to use means of passage safety assessment prior to choosing a route. It is pointed out that a relevant factor when assessing the safe passage probability is the cross-track error distribution law, whose impact is the subject of the research. The article analyses recent developments and publications that have begun investigating this subject, and highlights previously unsolved parts of the general problem. The results revealed two equivalent approaches, as well as a navigational safety parameter, which are used to determine the probability of safe navigation in narrow waters on the chosen route. The need to develop advanced predictive vessel motion models is noted, while many researchers study the design of an information system for vessel motion simulation with complex dynamic models and an intelligence system for vessel motion prediction that imitates the learning process of an autonomous control unit created with the use of the artificial neural network. Methods for identification of vessel manoeuvring models are shown. Based on the analysis of vessel hydrodynamics, a nonlinear model frame of vessel manoeuvring is established. The available publications suggest using compound laws of the first and second types for describing random errors in navigation measurements as an alternative to the normal distribution law. The article examines the dependence of the safe narrow waters passage probability on the cross-track error distribution law. The normal law and compound laws of the first and second types are considered as the cross-track error distribution laws. A formula for estimating the safe passage probability in the manoeuvring area is given, and expressions for the distribution function of the normal law and compound laws of both types are obtained. To assess the impact of the cross-track error distribution law for the same route, the safe passage probability for the normal distribution law, as well as compound laws of the first and second types, was calculated. For the same route, the probability of safe passage was calculated with the use of onedimensional and two-dimensional density models. It is shown that the average relative difference between the estimated safe passage probability for both models is 0.3%, which confirms the validity of using a one-dimensional cross-track error distribution density.

Science and technology achievements in the 21st century have qualitatively changed the traditional methods and techniques of Earth's surface research. Nowadays, remote methods have been used widely, when an observer or a measuring device is located at a certain distance from the study object in order to increase the observation area by several times. These materials can expand horizons of researchers, lead to increasing the flow of valuable information about already known objects and phenomena of the Earth.In presented research, there are some explanations about mechanisms of using natural processes to make forecast of changes in bottom topography in shallow water under navigation conditions. The key factor is the development of programs that can track changes in natural processes with displaying and fixation on electronic devices. Any research should preferably be carried out considering changes of the object over time and under the influence of various factors simultaneously and dynamically. In the article dynamic processes are divided into "significant" and "insignificant". This dependence is determined by the scale of space and time, where and when they occur. The concept of "scale factor" is introduced in order to determine significance of dynamic processes influence during research. Presented in the research dynamic map modelling method enables to make a forecast of siltation of the sea / river bottom for a given period of time. After comparing the forecast with the actual result, you can make corrections of the selected function, i.e. constantly improving the model. As a result of the research, we came to the following conclusions: 1. The “scale factor” should be entered in dynamic navigation map research and compilation with using different-scale data of the water surface and bottom topography; 2. It is recommended to enter a dynamic component into the information block of the navigation cartographic systems ECDIS and Inland ECDIS, allowing the skipper to see the position of the vessel, considering the wave height relative to the bottom in real time; 3. Above methods of parallel bottom topography transferring are based only on the data of statistical observations with using iterations. These methods usually give proper results on sandy and silty soils, where the relief has distinct wave-like forms, as well as relatively often repeated external influences with following the general main direction.

Published: December 2020

Language and culture are closely interlinked and learning a foreign language is impossible without contact with the culture of the language being studied. Idioms play an important role in recognizing and deeply understanding the cultural peculiarities of different peoples. The article analyzes the ways phraseological units can be expressed in Persian, based on 175 collected idioms with the somatic component “head”. The novelty of the work is that until now this topic has not been studied in the comparative Russian-Persian aspect. The research shows that in most cases Russian phraseological units with the «head» component have a full equivalent in the Persian language, i.e. they are transmitted by means of phraseologisms with somatism “سر” [sar].

Published: December 2020

The aim of this study was to explore the application of culturally responsive school leadership (CRSL) in an out of school time organization (OST). This was accomplished by analyzing how the actions of leaders both enabled and constrained CRSL. Research was conducted with Inspire Mentoring an OST organization that provides mentoring services to approximately 90-120 high school students of color from freshman through senior year. Approximately 60% of the mentors identify as people of color. The data collected for this qualitative case study occurred over 6 months and included: 6 semi-structured interviews with executive leaders and adult mentors, 5 observations of organizational meetings and community workshops, and reviewed documents from Inspire Mentoring. The leadership practices observed were analyzed using the behaviors of CRSL. This study suggest that positional OST leaders should become more connected to their community understanding longstanding inequities, interrogate their own worldviews, and work in tandem with minoritized youth and community members to address cultural youth development needs.

Authors: Plotnikov S. M.
Published: December 2020

The division of the total core losses in the electrical steel of the magnetic circuit into two components – losses dueto hysteresis and eddy currents – is a serious technical problem, the solution of which will effectively design and construct electrical machines with magnetic circuits having low magnetic losses. In this regard, an important parameter is the exponent α, with which the frequency of magnetization reversal is included in the total losses in steel. Theoretically, this indicator can take values from 1 to 2. Most authors take α equal to 1.3, which corresponds to the special case when the eddy current losses are three times higher than the hysteresis losses. In fact, for modern electrical steels, the opposite is true. To refine the index α, an attempt was made to separate the total core losses on the basis that the hysteresis component is proportional to the first degree of the magnetization reversal frequency, and the eddy current component is proportional to the second degree. In the article, the calculation formulas of these components are obtained, containing the values of the total losses measured in idling experiments at two different frequencies, and the ratio of these frequencies. It is shown that the rational frequency ratio is within 1.2. Presented the graphs and expressions to determine the exponent α depending on the measured no-load losses and the frequency of magnetization reversal.

Az abszolút tekintély : Karády Viktor Pierre Bourdieu-ről
Authors: Hadas Miklós
Published: December 2020

Karády Viktor, aki 1965-től csaknem negyven éven keresztül volt a párizsi Centre de Sociologie Européenne munkatársa, egy személyes hangú interjúban foglalja össze Pierre Bourdieu-vel kapcsolatos emlékeit. Beszámolója árnyalt képet ad a „fiatal zseni” szakmai kvalitásairól, a Bourdieu által 1975-ben alapított Actes de la rechereche en sciences sociales szerkesztésének műhelymunkájáról – mely tudományos folyóiratban a második legtöbbet publikáló szerző Karády lett a nyolcvanas éveket követően. Érzékletes leírásokat olvashatunk a Centre közösségének belső dinamikájáról és Bourdieu összetett, olykor paranoid vonásoktól sem mentes személyiségéről. S miután Karády egy bő évtizeden át szerkesztője volt a Revue francaise de sociologie-nak, s emellett igen közel állt Raymond Aronhoz, visszaemlékezése nem csupán Bourdieu és Aron konfliktusokkal terhelt kapcsolatáról számol be, hanem képet ad arról is, hogy a francia szociológia más műhelyeinek képviselői hogyan viszonyultak a Bourdieu-iskola tevékenységéhez.
Időrablók : A space rock mint a hetvenes évek magyar pop/rock zenéjének egyik meghatározó paradigmája
Authors: Havasréti József
Published: December 2020

A tanulmány a hetvenes évek magyar populáris zenéjének kontextusán belül a space rock történetével foglalkozik. Három meghatározó korabeli magyar zenekar: a Fonográf, az Omega, illetve a Mini együttes felvételei alapján rekonstruálja a space rock fontosabb megjelenési formáit, részben a progresszív rock, részben a jazz rock színtér működésén belül. Mindegyik zenekar valamelyik mainstream nemzetközi irányzat magyarországi verziójának tekinthető: a Fonográf esetében a folk rock, az Omega esetében a progresszív rock, a Mini esetében a jazz rock, illetve a jazz funk képezte a legfontosabb hatást. A magyar space rock számok szövegeiben olyan jellegzetes témák és motívumok jelentek meg, mint a (kozmikus) száműzöttség, a diaszpóratapasztalat, illetve különféle, a technológiai fejlődéshez kapcsolódó félelmek és utópiák.
Transitive L-verbs (grade 2) and transitive H-verbs (grades 1, 4, 5, and 6) in Hausa verbal compounds
Authors: McINTYRE Joseph
Published: December 2020

This paper examines Hausa verbal compounds in terms of the division of regular verbs
(verbs in the “grade system”) into verbs which have a High or Low tone first syllable. The
focus of the paper is the surprisingly small number of transitive L-verbs (verbs beginning
with a Low tone – “grade 2”) and their limited use of compound markers which contrasts
strongly with the frequency of transitive H-verbs (verbs beginning with a with High tone)
and their markers. I also describe several devices (e.g. grade-switching and covert subjects) which “allow” the formation of verbal compounds with transitive L-verbs.

The article identifies the competitiveness of machine-building enterprises on the example of SPE “Microterm”. According to the authors, research should be conducted by the method of SWOT-analysis, which reveals the specifics of a particular enterprise and improves the level of competitiveness of enterprises in modern business conditions. The authors conducted a SWOT-analysis by stages of filling in the SWOT matrix, processing (summarizing) the results and analysis of the results. At the first stage, the authors identified the strengths and weaknesses of the company. In the second stage, the main strategies of the enterprise were identified. In the third stage, the authors considered combinations of the SWOT analysis matrix. In the narrow branch aspect, this type of analysis helps to develop a multi-criteria model and perform its computer implementation (experiment), to obtain qualitative and quantitative interpretation, to determine directions for further development of the model, as well as ways of its practical use in product distribution (market) The authors determined that the main purpose of SWOT-analysis, as a matrix method, is to obtain reliable data on the company’s capabilities and threats to its promotion in the market of goods and services. Therefore, to achieve this goal before the SWOT-analysis are the following tasks: identifying marketing opportunities that correspond to the resources of the firm; identification of marketing threats and development of measures to neutralize their impact; identifying the strengths of the firm and comparing them with market opportunities; identification of the firm’s weaknesses and development of strategic directions for overcoming them; identifying the competitive advantages of the firm and the formation of its strategic priorities. Thus, during the practical application of the matrix method of SWOT-analysis, competitiveness was determined by the following features: qualitatively certain state (level) of the economy, stability of economic processes regardless of external and internal factors, resistance to various threats, development, resistance to the impact of external and internal threats, readiness and ability to create mechanisms to protect national interests, the ability to self-development and progress.

The article considers the role and methods of business modeling in the context of the implementation of innovative projects. The value of the business model as an instrument for innovation project planning for the enterprise, as well as for startups is argued. Considering the peculiarities of the company's adaptation to the external environment, as well as the degree of influence of management on the formation of the operating environment of the organization, it was determined that there are no identical business models. The plane of correlation of the business model, strategy, and business plan of the enterprise is considered: the enterprise chooses an effective business model that corresponds to its strategy and promotes its implementation, and the chosen business model lays the foundation for the business plan of the project. It is determined that depending on the method of income business models are trade, brokerage, service, subscription, community, information and media, affiliate, advertising, brokerage, licensing; depending on pricing – those that aim to maximize the value of the proposed idea and those that focus on minimizing the cost of implementing the idea. After analyzing the recommendations of an international consulting company, we came to the conclusion that the development of an effective business model takes place in three stages: offering value to the consumer; formation of a chain of creation of this value; determining the value that the company receives in this process, as well as ways to protect against competitors. Based on the generalization, it was found that different scientists in developing the structure of the business model of an innovative project identified their own hierarchy of values of its components. The necessity of using the canvas to ensure the speed and clarity of the formation of the business model is substantiated. The structure of the canvas most widespread in foreign practice is considered, as well as its modifications proposed for different purposes. After conducting research on existing practical approaches, the most significant aspects of business modeling of innovative projects were systematized.
