Influence of wave effect on fiber stress limit under tensile tests of composite material
Authors: Antypas I. R. , Karnoub Amer , Dyachenkо A. G.
Published: January 2020

Introduction. The response of composite materials to the impact of a certain kind of load is difficult to predict, therefore, research in this area has often been neglected. The work objective was to study the influence of the wave effect on the tensile strength of polymer composites of a fibrous structure.

Materials and Methods. In the tests, samples of multilayer materials of various thicknesses with continuous, long and short fibers that form a fabric, as well as a layered structure, were used. The number of layers corresponds to the resistance to the applied loads. Fibers of glass, carbon, kevlar, or their combinations were used. Isotropic materials – epoxide, polyester and vinyl ether – were used as binders.

Research Results. The tensile test results of homogeneous samples and samples of fibrous structure are obtained. In this case, the values of fiber angle varied. The stability of their intercomparison test results is established. The dependence of the maximum tensile stresses σmax, MPa, (on the vertical axis) on the fiber angle θmax is obtained. These stresses for a fibreless material amounted to 250 MPa. Normal and tangential stresses acting perpendicular to the fibers, as well as shear stresses of the layered material, are calculated. As follows from the analysis of the dependences for the significant tensile stresses and from the study on refraction in the section of the sample damage, it was established that the shear stress τ???????????????? was the cause of the fracture. Using an equation providing the compensation for the angle of inclination θ = 45, it was determined that the shear stress of the polyester is τху = 35 MPa. This was the stress that caused subsequently the destruction of the samples.

Discussion and Conclusions. The tensile stresses of the composite material decrease with increasing the fiber angle in certain areas. The destruction of all fiber samples occurred when the shear stress reached a value approximately equal to the shear stress at which the destruction of samples made only from a binder material happened. When the specimen broke, the fracture mode had the form similar to the shear failure; besides, at the moment of fracture, the object having a rectangular shape, being deformed at an angle, took the form of a parallelogram.

Published: January 2020

Introduction. The article is devoted to the search for a method of reducing the effect of friction links mobility industrial robot PR (production mechanism PM) with frequency-controlled electric drive (FCED) on the static error (accuracy) positioning of the working body (WB) when moving in a low speed zone. The random character of friction forces changes in the implementation process start-braking modes of induction motor (IM) operation create difficulties in performance specified technological process parameters. The formation of pulsating moments on the IM shaft, due to the stator IM current harmonics, combined with the friction torque of the moving parts in the IR (IM) guide, accompanied by a deterioration of the WB (IM output link) movement dynamics.

Materials and Methods. To correction the motion of the WB (PM output link) in the IM start-brake modes, the authors proposed to use dual-mode control of the Autonomous voltage inverter (AVI), providing software control of the IM stator current harmonics amplitudes and the corresponding regulation of the pulsating moments on the IM shaft by introducing a multiple "m — submodulation" of the AVI carrier frequency (CF). 

Results. The simplified representation of the FCED block diagram with local and global negative feedbacks (GNF) allowed to reveal the features of specific parameters influence on the static error δ and the FCED dynamic stability with the limiting gain of the corrective amplifier K1.

Discussion and Conclusions. The introduction of rotor "microvibration", allows the IM "conditionally reduce" the moving link friction force in the guides, reduce the drive power to overcome the friction forces. The use of dual-mode control AVI expands the scope of use of scalar control in process equipment, multi-link mechanisms of automated production, operating in the zone of "low and creeping speeds".
Problems of weld overlay of seating surfaces of pipe fitting and solutions
Authors: Poloskov S. S.
Published: January 2020

Introduction. A problem of providing the necessary functions of pipe fitting for blockage, control, distribution of the working medium flows under the most adverse operating conditions of oil and gas pipelines associated with abrasive particles, mechanical impurities, hydrogen sulfide, carbon dioxide and organic acids with sulfate-reducing bacteria, is considered.

Materials and Methods. High performance properties of seating surfaces of pipe fittings are provided through anticorrosive plating of alloyed and high-alloyed metals based on iron with the addition of chromium, nickel, cobalt and niobium. The basic weld overlay methods are analyzed: metalarc welding, nonconsumable and consumable-electrode weld facing in shielding gases, submerged arc surfacing. Advantages and disadvantages of surfacing methods implemented in recent years are noted: laser, plasma-powder and plasma-arc methods.

Research Results. Taking into account the automation capabilities, a high-tech process of robotic anticorrosive surfacing using a consumable electrode with an additional filler metal feed to the front welding puddle for shielding the thermal effect of the arc, is proposed. Industrial application of the proposed technology requires a set of studies related to assessing the effect of technological parameters on the quality of the deposited layers to provide the required operational characteristics of the fitting.

Discussion and Conclusion. It is proposed to carry out the above studies using physical and mathematical modeling of the anticorrosive surfacing, which reduces the time and number of experiments. Therefore, the primary task is to develop a mathematical model of the surfacing process with a consumable electrode with an additional filler wire and transverse vibrations of the welding burner. Such a model should virtually reproduce the surfacing process, as well as its thermal cycle followed by calculating the ratio of the structural components of the deposited metal and the substrate metal. The system of equations of the model should be solved by a special computer program. The algorithm presented for solving this class of problems will allow us to make a sound connection of the technological parameters of the surfacing process and the quality parameters of the formation of the deposited layers, to determine the program for their optimization to provide the required operational properties of pipeline fitting.
Increasing stable operation of the working body in crank presses
Authors: Kobzev K. O.
Published: January 2020

Introduction. Static and dynamic loading systems of the safety friction clutch (SFC) are investigated. A schematic diagram of the frictional contact of solids in the forging and stamping machines is synthesized. From the point of view of increasing the operational stability of the working body in crank presses, the following factors are considered: response time, current friction factor and a change in torque under static and dynamic loading of the safety clutch.

Materials and Methods. The response time of the SFC with differentiated friction pairs is determined. The sought indicator corresponds to the period of the uptime in which the load is amplified (between values of the rated torque and the response time). The parameters of a dual-mass system correspond to the parameters of an equivalent system that includes a clutch and key parts of the drive. The system elements include mass of inertia; mass of inertia including the engine rotor and the main (driving) part of the SFC; elastic connection with the specified value of the reduced angular stiffness. 

Research Results. Values of the load arising in elastic bonds not conditioned by the working body operation are specified. Formulas that should be used to determine the values of the driving moment and generalized coordinates are presented. Start conditions with an increase in the load value from the initial indicators are described.

Discussion and Conclusions. The dependence is found for calculating the minimum number of friction pairs of the basic friction group. It is shown that at this minimum, the gain used to implement an “ideal” SFC load characteristic, does not exceed the maximum permissible value, even if the value of the friction coefficient is maximum. A fundamental SFC model is presented, in which, with a minimum value of the friction coefficient, negative feedback does not work. In the functional diagram of the basic SFC version modernization, there is no negative feedback with a minimum value of the friction coefficient in order to increase the accuracy of operation and the rated load capacity.

A Comparative Study of Kalidasa’s Abhijnana Shakuntalam and Namita Gokhale’s Shakuntala: The Play of Memory
Authors: Solanki Pankaj
Published: January 2020

Shakuntala is one of the most acclaimed women characters of Indian Literature. For the first time Shakuntala’s character originated in The Mahabharata. Since then she has been represented in various texts in various languages of India. The present paper is an attempt to analyze the representation of Shakuntala by the authors from ancient times to the present. For this purpose ancient work Abhijnana Shakuntalam by Kalidasa and the modern work Shakuntala: The Play of Memory by Namita Gokhale are studied.

In Kalidasa’s Abhijnana Shakuntalam Shakuntala is the real daughter of Sage Vishvamitra and nymph Menka. However, she is adopted and brought up by Sage Kanva and his wife Gautmi. She is a rustic girl, brought up in a hermitage. With the progress of the play, she is married to King Dushyanta who forgets her because of a curse. Later, she was adopted by sage Kashyapa and his wife Aditi. She gives birth to a brave child Bharat and finally reunites with her husband.

Shakuntala: The Play of Memory by Namita Gokhale was Published in 2005 and it is a challenging work of Indian English fiction. Like the remakes of films there may be re-invention and re-interpretation of old myths embodied in literary works. In her masterpiece Shakuntala, Namita Gokhale has portrayed the story of a woman named after the heroine of Kalidasa’s classic drama Abhijnana Shakuntalam. In contrast to her legendary namesake, she is bold, spirited and imaginative. Right from her childhood she is conscious of the discrimination towards female. In her marriage with a mahasamant, Srijan, she feels suffocated by social customs. Hungry for experience she deserts home to travel with a Greek horse merchant, Nearchus. Together they travel far and wide and surrender to unbridled pleasures. Shakuntala assumes the identity of Yaduri: the ‘fallen woman.’ But she forsakes this life as well to meet her salvation in her death at Kashi.

Authors: ÖZDEN Altuğ , PROSPERİ Maurizio , DİOS-PALOMARES Rafaela , URSİTTL Armando
Published: January 2020

In this study, Turkish and Italian mills were compared in terms of efficiency scores and quality and environmental sensitivity. In the study, metafrontier method was used to determine efficiency scores, and indexes formed from responses obtained through questionnaires were used to determine quality and environmental sensitivities. In addition, the factors that affect the efficiency scores were determined by 1000 repeated trunceted regression analysis. The estimated efficiency scores for CCR, BCC and SCA models are respectively 74%, 80% and 93% for Turkish mills and 81%, 87% and 84% for Italian mills. It is also determined that Turkish mills and Italian mills can increase their olive oil production about 45% and 49% respectively without changing their existing inputs. When we check the factors which thought to affect the efficiency scores, we estimated that the number or partners and number of the permanent unskilled labour have negative effect and production managers experience, special training and quality index have positive effect on efficiency scores in Turkish mills. In the Italian mills, production managers experience, special training, quality index and environmental indeks, were found to have a positive effect on efficiency scores. As a result, Turkish mills have to increase their quality and environmental sensivities and decrease the number of partners, number of permanent unskilled labour for the competition of Turkish olive oil.

Yakut Emigration: Features of Adaptation and Communication
Authors: Antonov E. P. , Antonova V. N.
Published: January 2020

The issues of adaptation of Yakut emigrants forced to escape the revolution, the Civil War and the Gulag to different countries are considered. The role of Yakut emigrants in the preservation of national-cultural identity is described. Their participation in the civilizational dialogue between East and West is emphasized. A classification of the stages of the formation of local groups and microgroups of Yakut emigrants in the countries of the world is suggested. The approximate number, composition and territorial distribution of Yakut emigrants in China (the central group), Japan (southern Sakhalin), Finland, and the presence of microgroups in the USA and Australia are established. Attention is paid to the specifics of interaction of Yakut emigrants in the absence of a registered organization through communication, in which organizational, ideological, material activities were carried out. It is proved that correspondence was carried out in Russian, English, and various transcriptions of the Yakut script were used: Bötlingkowski, Novgorodovski, Cyrillic. Particular attention is paid to the high mobility of the Yakut emigrants, their desire to master new languages, qualifications and education for successful adaptation abroad. It is concluded that the Yakut emigrants failed to form a mechanism for the reproduction of ethnic identity (language, culture) in a foreign land. It was established that there was no organized opposition to repatriation by Yakut emigrants, but all returnees were unreasonably repressed by the NKVD.
V. G. Groman and the Transition to a Planned Economy in the USSR in the 1917-1930s
Authors: Kuznetsova O. N.
Published: January 2020

The question of the initial stage of the creation and functioning of a planned economy in the USSR is considered. The novelty of the study is seen in the analysis of the professional activities of the famous economist V. G. Groman, who first proposed the idea of centralized planning of the economy of Soviet Russia. The results of a study of the views of V. G. Groman are presented, with a refinement and addition of a number of facts of his biography: activities in 1917, expert work in the State Planning Commission and the board of the Central Statistical Office of the USSR. The question is raised about the fate of V. G. Groman in connection with criticism of his theory and subsequent arrest. The contribution of V. G. Groman to the scientific formulation of statistical work, as well as his socialist views, is evaluated. The question about the development of control figures as the first attempt to create an annual plan and the analysis of the “Gromanov concept” of the Soviet national economy as a whole has been raised. Attention is paid to the activities of a number of Soviet economists and to the identification of the interconnections between them and their colleagues in emigration, manifested in works and correspondence. A review of various approaches to planning and the creation of new methods and theories of planning in the works of V. G. Groman, S. G. Strumilin and S. N. Prokopovich is carried out.
Book “Masters of Deceit” by J. Edgar Hoover as an Ideological Basis of the Concept of “Red Scare” and Anti-Communism in the USA
Authors: Levin Y. A. , Buranok S. O.
Published: January 2020

The article is devoted to the formation of the image of such a phenomenon as the “Red Threat” in the literary work of FBI Director John Edgar Hoover. It is affirmed that a special position in the US executive power system, along with a certain popularity in the 30-50s of the 20th century, made Edgar Hoover and his ideas significant both for the internal political life of the United States and, to some extent, for the foreign policy of this country. It is emphasized that the publication “Masters of Deceit: the history of communism in America and how to deal with it” has become for its time an important ideological and political-philosophical basis in the formation of a powerful anti-communist movement in the United States against the backdrop of the Cold War. It is noted that this book is of interest from the point of view of analyzing how America’s major anti-communists understood the term communism , the history and essence of classical Marxism, Marxism-Leninism, the revolution in Russia and the changes that occurred in Soviet Russia after it, Stalinism and its consequences. It is indicated that the author of the book not only analyzes the most important moments in the history of world and Russian communism, but also tries to understand how the communist ideology has developed in the USA, who the American communists are, what their goals are, etc.
Management of the Turkestan Region Reform Preparation at the Beginning of the 20th Century: Economic Aspects
Authors: Mamaev A. V.
Published: January 2020

The economic aspects of preparing a new Regulation on the management of Turkestan at the beginning of the XX century are studied. The relevance of the study is justified both by the unexplored topic and the need to identify the prerequisites for the crisis situation of the Russian authorities in Turkestan on the eve of the 1917 revolution. The results of the analysis of the draft commissions of K. A. Nestorovsky, the meeting of P. A. Kharitonov, the proposals of Senator K. K. Palen and the Turkestan Governor-General A. V. Samsonov, criticism and comments from various departments, the initiatives of the Main Directorate for Land Management and Agriculture are presented. Particular attention is paid to the legal regulation of the issue of land, resettlement. The novelty of the study is in the fact that for the first time it traces the course of discussions and the process of constructing the legal foundations of the economic policy of the empire on the outskirts in the context of developing a new Turkestan position. It is proved that the Russian Empire intended to create conditions for the accelerated development of Turkestan in the interests of the mother country, but could not agree on conflicting needs and settle economic institutions new to the outskirts. It is emphasized that this was manifested in the failure of the many years preparation of the Regulation on the management of the region.
Sverdlovsk Region Industry and Its Consumer Market in “Dashing” 1990s: Mysteries and Paradoxes of Reform Era (according to Regional Statistics of 1992-2000)
Authors: Mamyachenkov V. N. , Plokhotnikov V. S.
Published: January 2020

The aim of the study is to analyze the state of industrial production in the Sverdlovsk region in the 1990s and its impact on the provision of population with consumer goods. The topic is relevant in the context of studying the impact of the crisis on the financial situation of population. The study was conducted on the materials provided by the Territorial body of the Federal State Statistics Service, with the involvement of scientific and journalistic literature on this issue. It is argued that the fall in production in the 1990s was caused by the collapse of the decades-old system of economic relations within the USSR and the Council of economic mutual assistance, as well as the reduction of purchases of materials and components from Western countries. It is declared that the decline in production in all industries of the Sverdlovsk region without exception continued until 1999. It is noted that after 1998 the industry of the region began to rise in all its branches, except for fuel. It is proved that the state of the consumer market in the segment of industrial goods for population did not correlate with the dynamics of their production in the region. It is concluded that the deep crisis of industrial production, which lasted until the end of the 1990s, in the market of consumer goods was largely compensated by imports of foreign consumer goods.

Authors: Oh Ahra , Park Kyungkyu , Yong Hyunju
Published: January 2020

In this study, the effect of perceived organizational support on affective commitment, in order to investigate the effects of perceived organizational support on employees' deviant behavior in the workplace, is firstly verified. Then the effect of affective commitment on employees' deviant behavior in the workplace(organizational deviant behavior and interpersonal deviant behavior) is verified. In addition, the mediating role of affective commitment on the relationship between perceived organizational support and deviant behavior is revealed. Organization-based self-esteem as the moderating variable that can strengthen the relationship between affective commitment and deviant behavior is verified. 252 employees were participated in the study and structural equation analysis was employed to examine the hypotheses. The following is a summary of the results. First, affective commitment increases as perceived organizational support increases. In other words, the higher employees' perception for organizational support are, the higher affective commitment are. Second, deviant behavior in the workplace decreases as affective commitment increases, that is affective commitment have contributed to the decrease in employees' organizational deviant behavior and interpersonal deviant behavior. Third, affective commitment was empirically verified to have a mediating effect between perceived organizational support and deviant behavior in the workplace. Also, the moderating effect of Organization-based self-esteem was verified in the relationship between affective commitment and interpersonal deviant behavior in the workplace. Based on these findings, it was determined that perceived organizational support is a significant antecedent of affective commitment and perceived organizational support can be recognized as the motive of affective commitment. The exchange between the employee and employer is positively related to employees' feelings of perceived organizational support and affective commitment to the organization and reciprocation in the form of lower levels of deviant behavior. Therefore, results also revealed that employees' perceptions of organizational support have an influence on their attitudes and behavior. Our findings emphasize the importance of valuing employees and investing in their well-being in the workplace.

Published: January 2020

Apesar de ser um dos principais produtores de amêndoa de cacau no mundo durante o século XX, a incidência de crises na lavoura e maior concorrência mundial no final desse mesmo século tornaram a atividade cacaueira no Sul da Bahia pouco rentável. Nesse sentido, em meados dos anos 2000, produtores procuraram agregar valor à amêndoa e tornar a atividade menos sensível a crises internacionais, por meio da produção de chocolate com alto teor de cacau. Diante disso, este trabalho analisa a estrutura do mercado de chocolate no Sul da Bahia, identificando a quantidade de marcas, estratégias produtivas, comerciais e de marketing. O levantamento de dados foi feito em plataformas online e visitas técnicas, entre agosto de 2017 e julho de 2018, e submetidos à análise qualitativa e análise de correlação. Nesse período foram identificadas 50 marcas, concentradas nos municípios de Ilhéus, Itacaré e Salvador. A produção é majoritariamente Bean to Bar ou Tree to Bar com alto teor de cacau, explorando nichos de mercado orgânico, vegano e biodinâmico. A produção é, principalmente, de chocolate 56,6%, 70% e 80%, cujos maiores mercados destino são: Bahia, São Paulo e Rio de Janeiro. Há dificuldade na comercialização, pois esta costuma ser feita por meio de terceiros. O mercado caracteriza-se por uma estrutura de concorrência monopolista e muito dinâmica, em que surgem novas marcas com muita rapidez no mercado, pois em setembro de 2019 já se contabilizavam 74 marcas, um aumento de 48% no período de 14 meses.

Este artigo procura delinear o paradigma do estado de exceção no pensamento de Giorgio Agamben, estabelecendo as devidas diferenciações em relação a forma como esse conceito é utilizado no debate público atual a fim que de que o paradigma agambeniano seja reconhecido em sua radicalidade. Para Agamben, o estado de exceção não diz respeito a uma categoria histórica identificável e nem se confunde com modelos estáticos ou legalmente prescritos, tais como a ditadura, o estado de defesa ou estado de sítio. Trata-se de uma criatura da tradição democrático-constitucional que se diferencia tanto da estrita facticidade, quanto da juridicidade ou da lacuna. O que afinal é o estado de exceção agambeniano? É força de lei sem lei como vigência sem significado da lei, anulando a diferenciação entre Estado de Direito e estado de exceção.

Developing immigrant integration policy in the Irish public sector: An international human rights and public sector duty approach
Authors: Murphy Clíodhna , Caulfield Leanne , Gilmartin Mary
Published: January 2020

This paper outlines a new approach to the development of immigrant integration policy in Ireland that is informed by an international human rights and public sector duty perspective. Based on a comprehensive review, the paper outlines the current state of immigrant integration policies in the Irish public sector, highlighting the limited awareness of this issue among public bodies. It also provides practical guidance for public bodies wishing to develop more effective immigrant integration policies, drawing from international human rights treaties and from examples of policy development in Ireland. Given the reality that Ireland is now a well-established immigrant-receiving country, the paper concludes that Ireland urgently needs a coherent and comprehensive approach to the development of immigrant integration policy. A human-rights-based approach offers such a method and would allow Ireland, through its public sector, to become a leader in immigrant integration policy development. This approach requires the elaboration of specific integration policies in order to ensure that migrant populations can practically access fundamental human rights such as housing, education, healthcare and employment.

Published: January 2020

A spectral method of the analysis of linear control systems is considered. Within the framework of this approach the σ-entropy of input signals and the σ-entropy norm of systems are introduced. The invariance of the introduced norm makes it possible to get invariant results of σ-entropy analysis.
A Trajectory Planning Based Controller to Regulate an Uncertain 3D Overhead Crane System
Authors: Aguilar-Ibanez Carlos , Suarez-Castanon Miguel S.
Published: January 2020

We introduce a control strategy to solve the regulation control problem, from the perspective of trajectory planning, for an uncertain 3D overhead crane. The proposed solution was developed based on an adaptive control approach that takes advantage of the passivity properties found in this kind of systems. We use a trajectory planning approach to preserve the accelerations and velocities inside of realistic ranges, to maintaining the payload movements as close as possible to the origin. To this end, we carefully chose a suitable S-curve based on the Bezier spline, which allows us to efficiently handle the load translation problem, considerably reducing the load oscillations. To perform the convergence analysis, we applied the traditional Lyapunov theory, together with Barbalat’s lemma. We assess the effectiveness of our control strategy with convincing numerical simulations.
Revisiting the Optimal Probability Estimator from Small Samples for Data Mining
Authors: Cestnik Bojan
Published: January 2020

Estimation of probabilities from empirical data samples has drawn close attention in the scientific community and has been identified as a crucial phase in many machine learning and knowledge discovery research projects and applications. In addition to trivial and straightforward estimation with relative frequency, more elaborated probability estimation methods from small samples were proposed and applied in practice (e.g., Laplace’s rule, the m-estimate). Piegat and Landowski (2012) proposed a novel probability estimation method from small samples Ep
h√2 that is optimal according to the mean absolute error of the estimation result. In this paper we show that, even though the articulation of Piegat’s formula seems different, it is in fact a special case of the m-estimate, where p
a =1/2 and m = √2
. In the context of an experimental framework, we present an in-depth analysis of several probability estimation methods with respect to their mean absolute errors and demonstrate their potential advantages and disadvantages. We extend the analysis from single instance samples to samples with a moderate number of instances. We define small samples for the purpose of estimating probabilities as samples containing either less than four successes or less than four failures and justify the definition by analysing probability estimation errors on various sample sizes.

Published: January 2020

In this paper, the implementation and tuning steps of the PID controllers were proposed for the position control of a mobile robot with differential steering. The purpose of this robot was the participation in a European amateur robotics contest, the mobile robot being developed in the Engineering Faculty of Sibiu, Department of Industrial Machines and Equipment. After a brief introduction of the mobile entertainment robot, followed by description of the robot’s different components and traction principles, several principles of tuning the PID controller for the mobile robot are presented. The paper ends with some general conclusions based upon the results obtained from studying the research and considering all the ideas that were introduced.
Abrasive Water Jet Cutting of Stainless-Steel Optimization by Orthogonal Array Approach
Authors: Perec Andrzej , Radomska-Zalas Aleksandra
Published: January 2020

The paper presents the use of Taguchi method to optimize the cutting of stainless steel by Abrasive Water Jet. Shown are the influence of the most important machining parameters, such a traverse speed, abrasive grains size and concentration of abrasive in the jet on the maximum depth of cut. Analysis of variance - ANOVA was used to determine the effect of machining parameters on the cutting depth. Based on the calculated signal/noise ratios for individual parameters of the cutting process, their impact on cutting depth was determined and optimal process conditions were determined in order to reach the maximum depth of cut. The empirical verification of this process was also performed by comparing the depth of cut predicted and achieved in the tests.

Authors: Petruse Radu Emanuil , Bondrea Ioan , Nicolae Ioan Cristian
Published: January 2020

The paper is focused on identifying the main requirements for developing a CPPS demonstrator prototype. This research aims to categorize the main components and interactions within a new manufacturing system which are required to accommodate a CPPS. The proposed CPPS demonstrator also includes the preliminary requirements identified from the discussions with the regional industry, so that the prototype of the production system could be easily understood and also be the basis for further collaborations. The identified requirements were structured according to the top-down principle focusing on accomplishing the major objectives to be achieved through the prototype of the production system but also on the detailed concepts of the product and the production stations, thus preparing the choice for a concrete technical solution.

There are extended agricultural areas in the world that can be utilized only with irrigation for crop production. Improper irrigation may induce unfavourable processes in the soil (e.g. secondary salinization). To investigate this problem existing in Hungary as well, 12 simple drainage lysimeters – which are useful equipment for the investigation of the water and salt balance of the soil – were used in an irrigation experiment in the Research Institute of Karcag. The basic goal was to investigate the possibility of the production of a salt-sensitive crop (green bean) in areas with unfavourable agro-ecological conditions. 6 lysimeters were irrigated with deionized water, while the other 6 with saline water of 1,600 mg/l salt content. We also used a soil conditioner (Neosol) during the experiment. Analysing the effect of the irrigation quality on the plant height of green beans, it can be established that the plants irrigated with deionized water were averagely 5.3 cm taller than the plants irrigated with saline water. Similar tendencies were characteristic of the average biomass (deionized: 93.5, saline: 62.5 g), the average root mass (deionized: 9.5 g, saline: 8.2 g), the number of pods (deionized: 17.1, saline: 11.9), and the pod yield (deionized: 137.9 g, saline: 85.9 g) values. However, all these values can be improved by soil conditioning combined with the optimization of irrigation.

During the study, the seeds of seven sweet basil cultivars were treated with 100 ppm solutions of gibberellic acid or ascorbic acid prior to a 14-day germination experiment. Values of the first day of germination, germination energy, germinability, mean time and rate of germination, and uncertainty and synchrony of germination were calculated. The results show that both of the substances altered the measured parameters, priming with gibberellic acid proving to be a more effective way to enhance the germination of basil seeds. Also, they revealed major differences among the germination parameters of the examined cultivars.

This paper presents the behaviour of five hyacinth varieties: ‘City of Haarlem’, ‘Blue Jacket’, ‘Miss Saigon’, ‘Jan Boss’, and ‘Double Prince of Love’ in forced culture under the influence of different culture substrates. For this purpose, the following parameters were monitored concerning the main characteristics: number of flowers from inflorescence, length of stem flower, earliness of flowering period, and the flowers’ blooming period. The results of this work show that in culture substrate garden soil and sand (1:1) the best results were obtained regarding the length of the floral stem, number of flowers from inflorescence, and flowering period, and less favourable results were obtained for bloom precocity.
