Published: November 2021

In this study, sequences analysis of some Citrus species distributed in Turkey's Aegean region was based on the cpDNA psbA-trnH  region. The sequences for psbA-trnH regions of the outgroups were retrieved from NCBI GenBank. Genomic DNA was isolated from healthy and green leaves. Total genomic DNA was extracted using GeneMark DNA isolation Plant Kit. The psbA-trnH region was amplified using primers psbA and trnH. DNA sequences were edited using the Sequencher 5.4.6. Sequencing data were analyzed using MEGA 6.0 software. Maximum likelihood (ML) tree was created to determine the relationships between Citrus taxa.  cpDNA psbA-trnH  sequences ranged between 426 and 470 nucleotides. Maximum likelihood phylogenetic tree is composed of two clades. The divergence values differed between 0.000 and 0.012. According to the results of the study, the separation of Citrus species in phylogenetic tree obtained with psbA-trnH sequence data was realized. However, it has been found that cpDNA psbA-trnH sequence populations of species belong together. In addition, the phylogenetic relationship between the sequence data of some species belonging to the Rutaceae family taken from NCBI and Citrus species was revealed.
Driver's License Suspension for Unpaid Fines and Fees: The Movement for Reform
Authors: Hirsch Joni , Sarathy Jones Priya
Published: November 2021

Nearly eleven million people in the United States have a suspended driver’s license for unpaid fines and fees. Laws that suspend, revoke, or prevent renewal of driver’s licenses and/or restrict driving privileges (i.e., registration holds and non-renewals) for nonpayment of traffic- and court-related debt criminalize poverty and disproportionately impact those with a lower economic status. These unproductive and harmful debt-based restrictions not only fail to increase collections of fines and fees, but also divert important public resources for law enforcement and courts away from public safety. The primary way in which these restrictions manifest themselves is through driver’s license suspensions, which are the focus of this article. However, several states also hold or suspend registrations or other required compliance documents, creating the same types of complications that result from a suspended license. The racial disparities of debt-based driver’s license suspensions are even more troubling, as individuals of color are more likely to experience poverty and to be stopped by law enforcement, as well as ticketed, arrested, charged, and convicted for traffic violations. To date, twenty-two states and Washington, D.C. have passed reforms that curb or eliminate the use of driver’s license suspensions and driving privilege restrictions for unpaid fines and fees. While most states continue to suspend, revoke, or prohibit license and/or vehicle compliance renewals for those with unpaid court debt, a growing movement for reform has taken hold. This Article will discuss the imperative for stopping debt-based restrictions and examine the rationales and impacts of two pathways to reform: litigation and legislation. This Article will lay out specific factors that jurisdictions should consider in their reform approach. Careful evaluation of these factors will ensure the greatest benefit while posing the least harm to those most impacted by these policies.
Features for friction stir welding of butt joints of casting VAL8 alloy with wrought 1565chN2 and AMg6M alloys
Authors: Berezina V.A. , Ovchinnikov V.V. , Luk'yanenko E.V.
Published: November 2021

The results of technological features for friction stir welding of butt joints of sheet blanks with thickness of 3 mm made of casting aluminum V AL8 alloy with wrought magnalium group 1565chN2 and AMg6M alloys are presented. It is established that the time resistance of the joints depends on the location of the welded alloys relative to the direction of tool rotation during friction stir welding. The ultimate strength of welded joints of VAL8 alloy with 1565chN2 and AMg6 alloys in automatic argon-arc welding is 0.82...0.84 of the ultimate tensile strength of VAL8 alloy. The grain size in the stir zone practically does not depend on the initial grain size in the alloys to be joined. The destruction of the joints made of VAL8 + 1565chH2 alloys under cyclic loading has multi-focal character and is initiated from irregularities on the surface of the weld. The discrete nature of the change in the chemical composition of the weld metal along the axis of the weld is revealed. The weld is formed by alternating strips of connected alloys with width of 30...90 microns.
Dekontruksi Pendekatan Kritik Sastra Terhadap Al-Quran Perspektif Amin Al-Khuli
Authors: Mofid Moh. , Hamdy Mohammad Zainal
Published: November 2021

The Qur'an is a collection of texts that require a very deep understanding and interpretation. Without interpretation, the text of the Qur'an remains a text that cannot speak. Literature is the result of human creation using the medium of written and spoken language, is imaginative, delivered in a unique way, and contains messages that are relatively. The purpose of this study is to explain the literary criticism approach to the Qur'an according to Amin Al-Khuli's view, so that we as Muslims understand more deeply about the contents of the Qur'an. Literary Approach as a Knife of Analysis in Understanding the Text of the Qur'an, Literary approach in interpretation actually emerged due to the large number of non-Arabs who converted to Islam and due to the weakness of the Arabs themselves in the field of literature, so it was felt necessary to explain to them about privileges and circumstances of the meaning of the content of the Qur'an. Then in the modern era the literary approach in the Qur'an was driven by Amin al-Khuli (died. 1968 AD) at the end of the twentieth century (20). He is a professor of Qur'anic studies at Cairo University. According to Amin al-Khuli, the Qur'an is the greatest book in Arabic. One of his theses states that the Qur'an is the greatest work of Arabic literature. The Qur'an has made the Arabic language never die, and along with its status as the language that God has chosen to convey His divine messages, makes the Qur'an itself as something that does not know dry.

PROSPECTS FOR THE USE OF VIBRATION DURING CUTTING MATERIAL
Authors: Omelyanov Oleg , Polievoda Yurii , Zamriі Mykhailo
Published: November 2021

Vibration is considered one of the effective ways to sharpen billets from difficult materials. The rational purpose of cutting modes with such a process allows you to increase the resistance of the metal-cutting tool, contributes to the creation of conditions to ensure constant crushing of chips. When cutting materials on the lathes of a turning group with the imposition of oscillations to the cutting tool, processes occur in the cutting zone, which differ from the processes arising from sharpening without oscillations.

The article discusses the possibilities of using vibration oscillations when cutting materials. Currently, new materials that have high strength characteristics, viscosity and plasticity are widely used in mechanical engineering, with an increase in the processability: cutting force increases and efficient power spent on cutting; The quality of surface roughness is worsen; the resistance of the cutting tool is reduced; The amount of heat formed in the cutting zone increases and the character of its distribution on the surfaces of the workpiece and the tool changes; the process of forming chips, its shrinkage and type; The intensity of the process of formation of outflow and its form. In this regard, the question arises about the search for rational processing methods, in particular, mechanical processing with cutting on lathes.

In this scientific work, the use of low-frequency oscillations is substantiated, which is the complex vibrational effect on the cutting process with the enforcement of solid chips, removal from the top of the cutter and preventing its formation, while ensuring the presence of a given roughness of the treated surface and an increase in the cutter resistance period. Research work in this direction is relevant and requires further research.
DEVELOPMENT OF DEVICE FOR RESTORATION OF PLACES FOR BEARINGS
Authors: Shvets Ludmila
Published: November 2021

Defects of case details include operation of openings under bearings within 0,2 - 0,4 mm on the party, operation of landing belts under sleeves. When restoring them, traditional methods are used: installation of repair bushings, application of polymer and electrolytic coatings, micron smelting, electrospark treatment, etc. Restored parts must have hardness and wear resistance with the parameters of the material of the reducing part (deviation 10 - 15%), have sufficient adhesion to the base metal, corrosion resistance in a humid environment, provide maximum contact area with the conjugate part, no pores, slag, foreign inclusions .

The method of restoration must eliminate the thermal impact on the part and be cost-effective.

Polymer compositions are usually brittle, subject to breakage and leaching. Surfacing causes warping of the part, bleaching of cast iron, the formation of slag and pores in the deposited layer. The electrospark coating method does not provide sufficient contact area with the conjugate part.

The use of electrolytes for iron seats in some enterprises is aggressive, unstable, requires heating or the use of expensive thyristor power supplies, followed by machining, as the microhardness of precipitation reaches a large value depending on the composition of the electrolyte and process modes, have high internal voltage.

The proposed device for restoring the bearings simplifies the existing method and meets the technical requirements of manufacturers in terms of machining accuracy (ovality, taper, coaxiality and surface roughness), provides high productivity (2 times higher than the productivity of specialized machines horizontally). and low cost (60 times lower than the cost of specialized machines).
AN APPROXIMATE METHOD FOR CALCULATING GRAIN FLOW IN A VERTICAL CYLINDRICAL VIBROSIEVE
Authors: Olshanskiy Stanislav , Slipchenko Maksym , Kharchenko Sergiy , Polievoda Yurii
Published: November 2021

A modified hydrodynamic model of a stable grain flow of an inhomogeneous mixture over the surface of a vertical cylindrical vibrating sieve is proposed under the assumption that the porosity of the mixture in the moving annular layer depends on the velocity of movement. A linear dependence of the porosity of the mixture on the velocity of movement are accepted, where higher speed corresponds to higher porosity.. The calculation of the velocity is reduced to solving an inhomogeneous differential equation of the Bessel type. Further, by "freezing" the variable coefficient of this equation, the problem has been simplified. This simplification is permissible due to the fact that the thickness of the moving layer of the mixture is much less than the radius of the vibrating sieve. As a result, the dependence of the velocity on the radial coordinate is expressed through the elementary functions. A compact formula for determining the maximum grain flow velocity is obtained. By integrating, in elementary functions, the formula for the average velocity in the layer is obtained. An approximate formula for the performance of the vibrating sieve by the mass of the exit fraction is derived. For this, it is proposed to calculate the corresponding integral approximately by the Simpson formula, so as not to calculate the values of special functions of large argument using the asymptotic formulas. It is shown that the named productivity significantly depends on the porosity of the grain mixture. In order to obtain information about the actual errors of the approximate formulas, we additionally carried out the numerical integration of the original non-simplified Bessel-type equation on a computer. A comparative analysis of the calculation results confirmed the small errors of the simplifications introduced into the equation of motion, as well as the adequacy of the theoretical results obtained.

By passing to a simplified differential equation, approximate formulas were derived and tested for calculating the main characteristics of the grain flow along a vertical cylindrical vibrating sieve, taking into account the change in porosity in the grain mixture layer from the velocity of movement. The work summarizes the known theoretical results obtained using hydrodynamic models of the motion of grain mixtures fluidized by vibrations. The generalization carried out slightly complicated the theory, because the final calculation formulas are quite compact and convenient in practical implementation.

Published: November 2021

Among the problems of mechanized harvesting of sugar beet, the most important is the cutting of the bud from the heads of root crops that are in the soil. Based on the analysis of numerous design developments and research, a two-phase method of performing this technological operation is promising at this time. Thus as a result of performance of the first phase the continuous copyless cut of all green massif of a top, its collecting and transportation is carried out and the following phase - clearing of heads of root crops of the remains of a top or additional pruning of heads. The effectiveness of this method of harvesting hyphae is obvious, because the cut green mass of sugar beet hyphae can be used as animal feed or to produce biogas. A rotary cutting device with a horizontal drive shaft can be used as a cutting device. The collection of the hitch from the entire width of the coverage of the hitch-harvesting machine can be effectively carried out by means of an auger conveyor, and the loading of the cut hitch into the vehicle - by means of a loading device of the throwing type. In the course of the research a new three-row hook-harvesting machine was developed, which implements the above principles of work. The hitch harvester is aggregated by frontal attachment to a wheeled tractor of traction class 1.4, equipped with a front PTO shaft. We conducted field experimental studies to determine the performance of this hitchhiking machine. For this purpose, a program and methodology for conducting such experimental studies were developed, the results of which were processed by statistical methods on a PC using the basic methods of regression and correlation analysis. As a result of the analysis of the obtained values it was found that the rational values of the speed of the hitch harvester are 1.5… 2.0 m ∙ s – 1 at the height of the cut of the hitch, which is equal to 0.02 m and the rotor speed of 1000 rpm-1. The operational indicators are obtained: productivity when aggregating with a wheeled tractor of class 1.4 - 2.15 ha • year – 1; specific fuel consumption - 3.02 kg • ha – 1; specific investments - UAH 291.33 • ha – 1; reduced operating costs - UAH 441.18 • ha – 1. The obtained results of researches of operational indicators of the developed three-row hook-harvesting machine turned out to be 1.5… 1.8 times better in comparison with serial hook-harvesting machines.
APPLICATION OF CURRENT LINES IN DETERMINING KINEMATIC CHARACTERISTICS IN STATIONARY PROCESSES OF PLASTIC FLOW OF METAL
Authors: Sivak Roman , Нunko Iryna , Zalizniak Roman
Published: November 2021

Methods of theoretical solution of problems in the processing of metals by pressure are insufficiently developed for practical use in the development and implementation of new technologies and improvement of existing ones. To meet the stringent requirements for the accuracy of determining the stress-strain state, it is necessary to have reliable information about the evolution of the development of the plastic deformation process at each point of the metal from the very beginning of the deformation. This will allow to obtain with high accuracy the important characteristics of the technological heredity of the products that they acquire as a result of their plastic processing. The first and important step in the calculations of the stress-strain state is to obtain the kinematic characteristics of the plastic flow of metal in the form of analytical dependences, which will formulate the patterns of deformation in the technological processes of metal forming.

The article considers the possibility of applying the method of current functions to determine the components of the strain rate tensor in established stationary processes of plastic deformation. It is assumed that in the case of axisymmetric plastic deformation of a metal in a channel with curvilinear boundaries, the kinematics of the process is similar to a plane flow. In obtaining the equations, the differential equation of current lines taking into account the incompressibility condition was used to determine the components of the strain rate tensor. To explain the physical meaning of the current functions, two infinitely close current lines were considered in the flow plane, and an expression was obtained for the flow through a finite transverse current tube. In the absence of radial velocity components at the boundaries, constraints are obtained that are imposed on derivatives of current functions at these boundaries. The developed method of calculating the kinematic characteristics of plastic deformation for established axisymmetric stationary processes will simplify the mathematical processing of the obtained results and increase the reliability of the determination of the stress-strain state.
INVESTIGATION OF TRANSITIONAL PROCESSES IN THE ADAPTIVE SYSTEM OF HYDRAULIC DRIVES OF THE MECHANISM FOR CUTTING AND UNLOADING STALK FODDER
Authors: Rutkevych Volodymyr
Published: November 2021

The problem of creating an energy-efficient and competitive mechanism for cutting and unloading stalk fodder from trench storage, by developing and justifying the parameters and modes of operation of the adaptive system of hydraulic drives of the mechanism is researched. The principal implementation of the adaptive system of hydraulic drive of the mechanism for cutting and unloading is proposed, in which a spool flow divider is placed between two executive hydraulic motors, which allows to regulate the supply of a U–shaped frame according to the load change which affects the cutting mechanism. The adaptive system of

the hydraulic drive of the mechanism allows to stabilize energy consumption for separation of a portion of a stalk fodder under the condition of change and fluctuation of parameters which essentially influence the process of separation and unloading of a stalk fodder from the monolith.

The transients in the adaptive systems of hydraulic drives of the mechanism for cutting and unloading of stalk fodder are received and analyzed.

As a result of the study, it was found that by changing the operating widths of the slide valve of the separator in the direction of reduction, a significant increase in the responsiveness of the hydraulic drive system of the mechanism for cutting and unloading to the changes in the loading on the cutting apparatus. As a result, the range of the adjustment of the feeding of the hydraulic cylinder of the U–shaped frame, which increases the efficiency of stabilizing the separation process from the monolith of block-portion of stalk fodder with a minimum power of the hydraulic drive system, is substantially expanded.

It is noted that the dynamic characteristics of the hydraulic drive of the mechanism for cutting and unloading stalk fodder adaptive to the load are influenced by the design parameters of the spool flow divider which implements feedback. On the basis of the conducted experimental research recommendations on the choice of constructive parameters of the spool flow divider are given.
IMPROVEMENT OF QUALITY INDICATORS OF THE PROCESS OF SOWING OF ROW CROPS
Authors: Olena Trukhanska
Published: November 2021

The level of technology in agricultural production, the quality and cost of the products are largely determined by the degree of perfection of the machines and units used. In resolving this issue in our country and abroad, work is underway to identify rational ways of tillage, namely the minimum energy and labor costs per unit of crop production.

Improvement of tillage technology is carried out in two main directions: minimization of tillage and combination of several operations in one pass of the agricultural unit.

Along with the application of fertilizers, one of the important operations in the cultivation of crops is sowing, which is performed by seeders and combined tillage and sowing units.

Seeders for sowing row crops are a special group of sowing machines. The modern market of agricultural machinery offers a number of field units suitable for sowing with different tillage technologies.

The main working body of the drill, which determines the quality of sowing, is the sowing machine, and the opener group is the most important unit of the drill. It must remove lumps of soil from the row area, prepare the seedbed, lay the seeds on its dense bottom, maintain a given depth of its laying, ensure good contact of seeds with the soil, create a loose mulching layer. Despite their diversity, a universal combined device is needed that meets all agronomic and operational requirements for sowing seeds with different physical and mechanical properties.

The most promising in this aspect are vibrating sowing machines, in which uniform sowing of seeds and fertilizers is achieved by transmitting their mass of oscillating motions.

At vibration of loose material with a certain frequency and amplitude of oscillations friction forces between separate particles decrease, it becomes more fluffy, mobile.

The method of sowing crops is determined by the required sowing density and the order of placement of plants per unit area. There are spreading, row, nesting, dotted and stubble methods of sowing and planting crops.

The choice of sowing method largely depends on the sowing qualities of the seeds of the crop and soil and climatic conditions. Depending on this, the size of the row spacing and the distance between the plants is taken.
APPLICATION OF VIBRATION EFFECTS IN BIOFUEL PRODUCTION
Authors: Polievoda Yurii
Published: November 2021

The considered effective way of processing by-products of biofuel production. The increase in the productivity of the technological line is achieved through the introduction of new vibration equipment for the primary purification of raw glycerin.

This study proposes a new approach to determine the efficient operation of a new machine, which is useful for the purification of glycerol based on the combinatorial process of centrifugation and vibration separation. The mathematical mechanical-rheological evaluations are developed based on the experimental results.

Has been proposed to evaluate the rheological characteristics of raw glycerin purification based on the experimental testing. A compression device has been used to determine the value of the unilateral deformation of this material, which allows simulating a condition of a material at various technological modes of processing. In this study, the changes of material properties under centrifugation and vibration separation processes in a vibrocentric machine have been investigated.

At a choice of optimum technological parameters of processing of food masses by means of vibration methods of rheology are widely applied. In particular, the interaction of the working body of the machine with the treated environment.

In order to find the optimal parameters of the technological regime, the process was considered comprehensively from the standpoint of mechanics and rheology. The methods of mechanics describe the interaction of the working body with the treated environment as a mechanical object; rheology, in turn, allows you to reveal the internal processes in the environment.

The system under study can be attributed to the elastic-viscous medium, which is described by a phenomenological model consisting of interconnected elastic and viscous elements.

The issue of accelerated creation of efficient and energy-saving hydraulic drive of stem forage separator from trench storages by simulation modeling of technical systems. It is noted that the use of simulation allows to avoid significant investments required for the manufacture of a prototype of an agricultural machine, provided a detailed study physical model of the hydraulic drive of the stem feed separator. And also allows you to check the adequacy of the results obtained in process of mathematical modeling, and determine the necessary improvement of the proposed hydraulic drive. A fundamentally new constructive-technological scheme is presented stem feed separator from trench storage that allows to carry out process of unloading of a stalk forage from trench storages according to zootechnical requirements. The stand for simulation modeling of transients in the hydraulic drive of the stem forage separator from trench storages is offered. The design of the experimental stand also allows to investigate the hydraulic drive of the stem feed separator in the dynamic mode, when changing the technological load on the working bodies and changing the parameters of the adaptive fluid flow separator and the system in general. As a result of research and analysis of transients in the hydraulic drive, a fairly close coincidence of the results of mathematical and simulation modeling of the hydraulic drive of the stem feed separator, which allows us to recommend obtaining the calculated dependencies for use in the development hydraulic drives of stem feed separators.

High requirements for the energy efficiency of residential construction projects being built, a high level of competition between building organizations, as well as a wide variety of applied materials and technologies determine the high importance for solving of the problems connected to determination of the characteristics of external multilayer wall structures. On the basis of the results received during the analysis of the relevant scientific developments, it has been concluded that the existing tools are limited in terms of taking into account thermal performance indicators as criteria for determination of the optimal values for the characteristics of the structure – particularly, the thickness and thermal conductivity of the structural layers. The expediency of conducting of the research aimed to the development of a tool for the determination of the characteristics for a multilayer wall structure on the basis of quadratic programming has been substantiated.

This study aims to investigate how the different leadership levels can apply change management successfully in larger organisations, in order to facilitate business excellence. First, change models and leadership theories are analysed under EFQM principles, as it is selected as the framework for excellence. Then, a theoretical change management process is synthesised in alignment with leadership organisational levels. The main challenge of this research is to adequately connect theory about leading organisational change with practice. The research process is enriched by 6 semi-structured interviews in two different case studies, while the previous findings are validated through 3 structured interviews in a third case study. The analysis shows that although leaders believe that they identify the need for change, sometimes they do not, or they make sense of it too late. As such, a five-step change process model is created as the conclusion of the theoretical and case studies analyses. The value of this research is the connection between theory and practice as it tries to identify the responsible gaps for wrong or not fully successful organisational change projects. The suggested model simplifies the theory into practical steps while the success factors ensure that the enablers can support change efficiently. Further research based on the adoption of Senge’s systems theory for network leadership level is recommended to organisations.

Teknologi berkembang begitu pesat, di abad 21 ini teknologi bukan lagi menjadi sesuatu yang sulit ditemui. Para milenial mendominasi penggunaan TIK dalam kesehariannya. Tak jarang anak usia dini lebih pandai menerapkan TIK dari pada orang tua atau gurunya. Anak usia dini tergolong generasi digital natif. Generasi digital natif ditandai dengan kemudahan anak mengakses dan berinteraksi dengan peralatan digital sejak dini. Guru PAUD dituntut memiliki kreativitas di dalam mengajar, jika guru masih mengguakan cara lama atau pembelajaran tradisonal di abad 21, maka kemungkinan anak kurang antusiasme di dalam kegiatan pembelajaran. Kondisi tersebut, menjadi dasar dilakukan pengamatan. teknologi, akan tetapi diperlukan juga subtitusi untuk anak. Pengamatan ini menggunakan metode kualitatif studi kasus. Dari pengamatan ini diperoleh hasil bahwa guru TK yang tidak terampil TIK cenderung pasif dan memiliki minat rendah dalam mengasah kemampuan TIK. Hal ini nampak dari wawancara dan obeservasi yang telah dilakukan pada beberapa narasumber. Teknik analisa data yang digunakan yaitu penjodohan pola dan pembuatan penjelasan untuk memaknai kondisi pada TK.
