Urgency of the research. Positive experience with the use of CLT panels in distress has been observed for a long time in Eastern Europe and is considered necessary to study the strength and factors affecting the load-bearing capacity of this type of structures made of transverse glued wood (CLT). Target setting. An integral important issue for CLT panels is torsional strength, which has a scheme of destruction by chipping layers of boards and requires the establishment of the main factors of influence to assess the load-bearing capacity of this type of stress. Actual scientific researches and issues analysis. Shear and torsional strength is one of the main issues in the strength of CLT panels as an orthotropic plate, which has interested many researchers from different countries, including Blaß, Görlacher (2002) [1], Bosl (2002) [4], Jeitler (2004) [11 ], Jöbstl, Bogensperger, Schieckhofer [12], Wallner (2004) [18], Bogensperger, Moosbrugger (2007) [3], Silly (2010) [14, 15], Hirschmann (2011), Blaß, Flaig (2012) [2], Dröscher, Brandner, Kreuzinger, Sieder (2013), Dietsch (2017), Serrano (2018). Uninvestigated parts of general matters defining. The issue of identifying factors influencing the bearing capacity of PKD panels during shear and torsion has not been resolved.. The purpose of the article. Establishment of the main factors of influence for an estimation of bearing capacity of CLT of panels at shift and torsion.. The presentation of the main material. Cross laminated timber, as a sheet building material based on layers of boards with mutually perpendicular arrangement of boards in adjacent layers, has a number of important factors that affect the strength of CLT panels in shear and torsion. Thirty years of world experience in the use of CLT panels in multi-storey construction proves the importance of considering different models of panels as diaphragms and rigid frame elements from panel-frame buildings. Particular attention is paid to the nature of the destruction of the panel for chipping, both in the plane of the panel and from the plane. The importance of this type of stress state is further enhanced by a group of different shear or group of test schemes according to EN16351, including rolling shear strength tests. The latter value of strength is a new phenomenological feature of CLT panels. Conclusions and suggestion. Based on experimental studies of the strength of the glued rods in the cross section of CLT panel, the change in strength depending on the diameter of the metal rod and its location in the cross section, which is characterized by alternation of mutually transverse layers of boards.

Research rationale. The current state of the natural environment in the northwestern part of Ukrainian Polissia is characterized by a huge-scale changes in cultivated lands. The reasons for the disturbance of the structure of natural landscapes are the unauthorized extraction of gemstones, in particular, amber. Problem statement. For Ukraine, this issue has become particularly acute as the environmental consequences of illegal mining are quite disastrous as far as the disturbed biotopes cannot be restored to their original state in a natural way without human intervention, thus they need to be recultivated. Analysis of recent studies and publications. The researches that cover the agenda include the issues of monitoring and determination of locations of lands disturbed due to illegal amber mining as well as the use and classification of lands disturbed as a result of mining industry’s activities. Uninvestigated parts of general matters defining. The introduction of an economic and legal mechanism for compensating by the violator for damage caused by illegal amber mining and the failure to carry out land reclamation after the completion of mining operations will ensure more effective protection of the interests of the state and territorial communities as well as the rights of owners and exploiters of land plots, and will have a positive impact on reducing breaches of law in the area of land utilization. Objective of the research. The purpose of the study is to assess the impact on the environmental condition of the Rivne oblast as well as economic assessment of the extent of damage caused by illegal gemstones mining. Statement of basic materials. Obvious signs of negative anthropogenic impact related to unauthorized use of subsurface resources have been established, namely: the unauthorized removal of the fertile soil layer, excitation of the entire structure of the soil cover, hydrological regime, geological structure of the subsoil area, destroyed vegetation. At the same time, disturbance of land, both for forest and agricultural purposes of various forms of ownership. Following the researches, the extent of damage and compensation to the state resulting from the illegal mining of gemstones was determined. Conclusions under the article. On the territory of the Ukrainian Polissa the technogenic sand massifs and badlands are being intensively formed, which area is constantly increasing. The spread of such formations on the lands of forestry and agricultural purposes creates a threatening ecological and economic situation throughout the region.

OXIDATIVE-ORGANOSOLVENT DELEGIFICATION OF WHEAT STRAW

Urgency of the research. Expansion of the raw material base of the pulp and paper industry of Ukraine takes place through the use of alternative types of vegetable raw materials, namely wheat straw, and the improvement of environmentally friendly oxidative-organosolvent technology for the production of straw pulp. Target setting. Methods for the delignification of vegetable raw materials using the oxidant – hydrogen peroxide – are currently available. The disadvantage of these methods is the high consumption of the oxidant, which constitutes 90 % by weight of absolutely dry raw material that significantly increases the cost of technical cellulose. Therefore, it is necessary to improve the technological parameters of the delignification process of wheat straw with hydrogen peroxide in acetic acid. Actual scientific researches and issues analysis. Recent open-access publications have been reviewed, including literature on oxidative-organosolvent delignification methods of plant material using peroxoacids. Uninvestigated parts of general matters defining. Investigation of technological parameters of oxidative-organosolvent delignification for the reduction of oxidant consumption and determination of optimal values of temperature and duration of the delignification process of wheat straw with the mixture of hydrogen peroxide in acetic acid. The research objective. Investigation of straw pulp production method in order to reduce the consumption of cooking reagents while increasing the physical- mechanical properties and yield of the target product. The statement of basic materials. A method of obtaining straw pulp from wheat straw shreddings in acetic acid media with the hydrogen peroxide consumption 50 % by weight of absolutely dry raw material was investigated. The content of the main components in the raw vegetable material was determined. The effect of the delignification conditions, namely the temperature and cooking duration, on the yield of the fibrous semi-finished product, the content of residual lignin and the content of cellulose was studied. It was shown that the increase of temperature from 70 °C to 90 °C and duration of vegetable raw materials processing from 60 to 180 min lead to the decrease in yield by 28 %, the content of residual lignin by 6.5 %, while the cellulose content in the fibrous semi-finished product increased by 21 %. Calculated regression equations adequately described the experimental data and could be used as a mathematical model of the delignification process of wheat straw by hydrogen peroxide in acetic acid media. Optimal values of technological parameters of the wheat straw cooking process were determined using the method of multicriterion optimization of the delignification conditions. Conclusions. Calculated regression equations adequately described the production process of straw cellulose by hydrogen peroxide delignification in acetic acid. Established optimal technological parameters provided obtaining a final product with high quality indicators (yield 78.2%, residual lignin content 3.6%, cellulose content 65.4%, breaking length – 6200 m, punching resistance 210 kPa, tearing resistance – 425 mN, folding endurance 625 n.d.b.).

Introduction to the LXX ed. by Siegfried Kreuzer

Reviewed by: Introduction to the LXX ed. by Siegfried Kreuzer Bradley C. Gregory siegfried kreuzer (ed.), Introduction to the LXX (trans. David A. Brenner and Peter Altmann; Waco, TX: Baylor University Press, 2019). Pp. xxx + 671. Paper $69.95. Although titled Introduction to the LXX, this volume is actually somewhat of a hybrid of a traditional introduction to the Septuagint and a handbook for use as a reference work. The choice of this title makes sense because this volume represents the first installment in a new series entitled Handbook of the Septuagint, and so that title could not have been used. Future volumes in this series plan to delve into particular aspects of LXX studies such as the textual history, the theology, the language, and the reception history of the LXX (p. xi). The introductory section of the work (pp. 3–62) contains two essays covering the usual topics found in introductory textbooks such as those by Jennifer Dines (The Septuagint [Understanding the Bible and Its World; London: T&T Clark, 2004]) and Karen Jobes and Moisés Silva (Invitation to the Septuagint [2nd ed.; Grand Rapids: Baker Academic, 2015]). In “The Origins and Transmission of the Septuagint,” Siegfried Kreuzer gives a balanced and able discussion of the historical, cultural, and political background, the emergence of the LXX, and important terminological issues. He then discusses the early Hebraizing revisions, the later Jewish translations, Christian revisions, and the transmission and influence of the LXX in late antiquity. His navigation of the debate over whether the LXX originated as a Ptolemaic or Jewish initiative is representative of the nuanced character of this essay. He argues that the primary initiative arose from the Jewish cultural context and educational needs but the indirect role played by the positive reception of the project among the Ptolemies helps to account for literary traditions that presented it as a Ptolemaic initiative (p. 19). In the second introductory essay, “Overview of Textual Witnesses to the Septuagint,” Kreuzer and Marcus Sigismund present in table form a chronological listing of the most important [End Page 529] textual witnesses from the third century b.c.e. to the third century c.e. Importantly, this list also includes other relevant witnesses such as Hebrew manuscripts from Qumran, as well as quotations of the LXX and daughter translations. Sections 1–6 of the book present introductions to the individual books of the LXX: Pentateuch, Historical Books, Later Historical Books and Narratives, Psalms and Odes, Wisdom Books, and Prophetic Books. Most of the individual chapters are between seven and fifteen pages in length and follow the same format. Chapters begin with a substantial bibliography, then discuss “Texts and Editions,” “Translation Technique: Time and Place” (or general matters of provenance for works composed in Greek), “Linguistic, Textual, and Theological Profile,” before concluding with “Prospects for Research.” Section 1, on the Pentateuch, includes the following contributions: “From the Torah to Nomos: Perspectives of Research on the Greek Pentateuch,” by Martin Rösel; “Genesis,” by Martina Kepper; “Exodos/Exodus,” by Peter Schwagmeier; “Levitikon/Leviticus,” by Martin Vahrenhorst; “Arithmoi/Numeri/Numbers,” by Gilles Dorival; and “Deuteronomion/Deuteronomium/Deuteronomy,” by Melvin K. H. Peters. Section 2, on the Historical Books, contains “Jesus/Josue/Joshua,” by Cornelius G. den Hertog; “Kritai/Iudices/Judges,” by Natalio Fernández Marcos; “Ruth,” by Eberhard Bons; “Basileion I and II/1–2 Kingdoms/1–2 Samuel,” by Philippe Hugo; “Basileion III/3 Kingdoms, 1 Kings,” by Martin Meiser; “Basileion IV/4 Kingdoms/2 Kings,” by Julio Trebolle Barrera; “Paraleipomenon I and II/1–2 Chronica/1–2 Chronicles,” by Adrian Schenker; “Esdras I/1 Esdras/3 Ezra,” by Dieter Böhler; and “Esdras II/2 Esdras/Ezra-Nehemiah,” by Dieter Böhler. Section 3, on the Later Historical Books and Narratives, comprises “Esther/The Book of Esther,” by Kristin De Troyer; “Judith/The Book of Judith,” by Helmut Engel; “Tobit/The Book of Tobit/Tobias,” by Katrin Hauspie; “Makkabaion I/1 Maccabees,” by Michael Tilly; “Makkabaion II/2 Maccabees,” by Tobias Nicklas; “Makkabaion III/3 Maccabees,” by Wolfgang Orth; and “Makkabaion IV/4 Maccabees,” by Robert J.

Investigation of technological parameters of straw cellulose production in the system acetic acid-hydrogen peroxide-water-ethyl alcohol in order to increase the physical and mechanical parameters and the yield of the target product.The statement of basic materials.A two-stage method for producing straw pulp from wheat straw at the first stage has been investigated. Delignification was carried out in the “acetic acid-hydrogen peroxide-water” environment at a hydrogen peroxide consumption of 50% of the mass of absolutely dry raw material (a.d.r.m.) and at the second stage of cooking, 40 volume% of ethyl alcohol was added to the cooking solution to replace the same amount of spent cooking solution after the first stage. The content of the main components in the original plant raw materials isdetermined. The influence of delignifica-tion conditions, namely temperature and duration of cooking on the yield of fibrous semi-finished product, the content of re-sidual lignin, cellulose content and strength indicators was studied. It is shown that the temperature increase at the first stage of the process from 50 ºС to 70 ºС, at the second stage from 80 to 100 ºС and the duration of processing of vegetable raw materials from 60 to 120 min. and from 60 to 180 minutes, according to the stages of the delignification process, leads to a decrease in yield by 7.9-18.9%, the residual lignin content by 4.27-9.11%, while the cellulose content in the fibrous semi-finished product increases by 10.1-15.8%. It is investigated that the indicators of mechanical strength of the obtained fibrous semi - finished products increase with increasing temperature and duration of processing of raw materials. Regression equa-tions for each stage of cooking are calculated, which adequately describe the experimentaldata and can be used as a mathe-matical model of the process of delignification of wheat straw with hydrogen peroxide in acetic acid. The method of multicrite-ria optimization of delignification conditions determines the optimal values of technological parameters of the wheat straw cooking process. The lignin-carbohydrate diagram of delignification of vegetable raw materials is offered. The number in which various methods of delignification of wheat straw are located on efficiency is defined.Conclusions. The technology of obtaining straw fibrous semi-finished products in the system "acetic acid-hydrogen per-oxide-water-ethanol" has been developed. Regression equations are calculated that adequately describe the experimental data and can be usedas a mathematical model of the investigated method of obtaining straw fibrous semi-finished product. The optimal technological parameters are established, which ensure the production of the final product with high quality indicators. The lignin-carbohydrate diagram of delignification of wheat straw stalks by different cooking methods is given.

MODELLING OF ROBOT MANIPULATION IN INTEGRATED PRODUCTION

Urgency of the research. Cell production has become one of the most important studies of the arrangement of production systems. This production philosophy is based on the fact that the products are similar in shape and production processes. This allows parts to be grouped into groups that they share during their processing, ensuring an economic effect.Target setting. Automated production systems are built with large investments. The result is small-scale production automation cells, including industrial robots, including handling automation. These automation islands did not meet expectations in terms of costs, commissioning dates, meeting production deadlines, achieving planned performances, so attention must be paid to integrated production. Actual scientific researches and issues analysis. Integrated production reduces material handling and transport time. By making the product more time on the machinery and less time on the road. Because the parts move in the chamber and not in the entire factory, travel time and distance are reduced, leading to a reduction in material handling costs, which represents between 20 and 50 % of the total operating costs. Uninvestigated parts of general matters defining. Most articles and other publications on the problem of modeling integrated manufacturing alleviate the problem of modeling a specific cell. In my article I will solve a production cell in general without specific properties. The research objective This paper focuses on the integrated and logistic of the style of material flow, suitable for realization manufacturing and logistics network. Solution base is defining of mission, objectives and goal integrated of the style of material flow. The core of solution is analysis of strategy on integrated. The result of solution is to define tools integrated and formation evolution profile of the style of material flow. The statement of basic materials.In general, the key to building integrated production is group technology based on the principle of material flow analysis. The problem of modeling integrated production points to possible variants of solutions based on the analysis of material flows. However, considering only this criterion is insufficient for practice, because it does not consider e.g. about the number of pieces. Conclusions. These relationships are representative of some approaching the importance of parameterization, which remains open and accessible to address other tasks to optimize the production system.

ДОСЛІДЖЕННЯ ОБЧИСЛЮВАЧІВ ПРИСКОРЕНОГО ОБЧИСЛЕННЯ ДАНИХ ЗБІЛЬШЕНОЇ РОЗРЯДНОСТІ НА ОСНОВІ ОДНОВИМІРНОГО КАСКАДУ КОНСТРУКТИВНИХ МОДУЛІВ

Urgency of the research. The study of computers to calculate data of increased bit size and take into account the impact of methods of their description on the implementation of FPGA will increase the speed of data processing, and more efficient use of FPGA resources is certainly an urgent task. Target setting. Accelerating the process of calculating data of increased bit size places additional demands on the implementation of elements of computer systems and computer systems in general. Actual scientific researches and issues analysis. The speed of computing high-bit data used in an FPGA depends on the methods used to describe it, but these methods also affect hardware costs. Uninvestigated parts of general matters defining. There are no theoretical and experimental studies of high-bit computers to calculate the operations of modules based on one-dimensional cascades of structural modules based on FPGA. The research objective. The aim of the work is to describe and study computers of complex operations on the module on the data of the increased bit size in the basis of FPGA. The statement of basic materials. Computers of complex operations on the increased bit module are described by the method of functional description using standard VHDL operators and the method of structural description in the form of a one- dimensional cascade of structural modules. The dependences of speed and hardware costs on the bit are determined experi- mentally taking into account the internal structure of a certain family of FPGAs for each of the methods of description. Conclusions. The use of the method of functional description by typical tools based on FPGA does not allow to take into account the peculiarities of large data processing algorithms, which leads to excessive hardware costs. The proposed method of structural description using a one-dimensional cascade of structural modules in the language of hardware description demonstrates better results and allows a more flexible approach to the use of FPGA hardware resources. Reducing the hardware cost of implementing high-bit computing tools within a particular FPGA, by freeing up additional resources, increases the bit size of the data being processed at no additional cost to replace the hardware with an overall increase in the performance of the computing element or system.

ЗАХИЩЕНА СИСТЕМА РОЗУМНОГО БУДИНКУ З ВИКОРИСТАННЯМ INTERNET OF THINGS

Urgency of the research. Today, the Internet of Things (IoT) is firmly entrenched in the lives of billions of people around the world. IoT is used in many areas of human activity - industry, everyday life, medicine, education, urban management and others. However, the increase in the number of connected devices leads to an increase in safety risks - from causing physical harm to humans with these devices to damage to complex technological equipment. That is why the issues of ensuring the protection of IoT systems are relevant. Target setting. Comprehensive protection of IoT systems is possible only with reliable network, software and technical protection of devices, equipment and communications of which these systems consist. Given that the above objects and methods of their protection can be combined into a separate secure system of a smart home, its development is an important theoretical and practical task of cybersecurity. Actual scientific researches and issues analysis. Today, there are many publications that analyze IoT security issues and suggest ways to solve them, but there is no work that would develop a separate model of IoT protection on the example of a smart home. Uninvestigated parts of general matters defining. Analyzing the multilevel architecture of IoT systems and features of cloud platforms of the Internet of Things, highlighting potentially vulnerable components of these complex solutions (access control system to IoT device and cloud platform; clouds, mobile applications and web interfaces of devices; software updates; device memory ; local data warehouses; hardware and software interfaces of devices; network services of devices; ecosystem of communications, including network traffic) it can be argued that building a secure system of a smart home using IoT will increase the level of security of these systems. .

ПРОЦЕС БАЛАНСУВАННЯ ШПИНДЕЛІВ ШЛІФУВАЛЬНИХ ТА ШВИДКІСНИХ ФРЕЗЕРУВАЛЬНИХ ВЕРСТАТІВ У ДВОХ ПЛОЩИНАХ КОРЕКЦІЇ

Urgency of the research. In connection with the creation of new types of Metalworking equipment and other machines that increase labor productivity, there is a problem of centering and balancing unbalanced technological systems during their manufacture and regime change of imbalances during operation. Currently, most grinding machines and high-speed milling machines provide manual balancing of the grinding wheel and the milling tool. The disadvantage of this method is the need to stop the equipment or change the technological and operational modes of operation. A more effective way is to integrate balancing devices into the kinematic structure of a grinding or milling machine and perform balancing automatically during the machine's running time. Target setting. When implementing automatic balancing of the spindles of grinding and high-speed milling machines on the move of the machine in two planes of correction, expensive, complex vibration measuring equipment, electronic control units and comparison of machine vibrations are necessary. In addition, the technology of automatic balancing on the move of the machine to compensate for moment and dynamic imbalance requires solving the problem of reducing residual imbalance while increasing the reliability of the drive and other devices. Analysis of recent research and publications. The work considered the latest publications on this topic, which are presented in the public domain, including the Internet. Uninvestigated parts of general matters defining. A significant proportion of current approaches to balancing the spindles of grinding and milling machines during operation require stopping the machine and balancing in manual mode. In determining the load on the spindle due to an imbalance, we also should note that the dynamic cutting forces (e.g., caused by intermittent operation of the cutter or grinding wheel wear) are often much higher than centrifugal forces caused by admissible residual imbalances. When automatically balancing the spindles of grinding and high-speed milling machines, it is necessary to correctly select the position of the correction planes relative to the grinding and milling tools. Therefore, determining the parameters of the imbalance in the two planes of correction and the condition of automatic balancing is an urgent part of the overall problem that is being solved in this scientific study. The research objective. The purpose of this scientific work is to develop a method for automatic balancing of spindles of grinding and high-speed milling machines in two correction planes with the determination of the main imbalance vector and representation of the geometric (mass) characteristics of the rotor through equivalent components in two correction planes. The statement of basic materials. When processing workpieces on high-precision grinding machines and high-speed milling machines, deviations from the geometric accuracy and quality of a given surface are largely determined by the amount of imbalance that occurs when the spindle rotates. It is known that the technological imbalance is the result of such objective reasons as mismatch of the workpiece axis and the spindle axis, uneven mass distribution in local areas of the workpiece, radial runout of the workpiece and tool, different material density. On modern grinding and milling machines, the spindle speed is several thousand revolutions per minute, so each newly installed workpiece must be subjected to balancing, usually together with a chuck, mandrel or collet. Conclusions. As a result of the research, the directions of vectors of static and dynamic imbalance of spindles of grinding and high-speed milling machines after balancing in two correction planes are determined. By moving the correction plane along the axis of the machine spindle, the reactions in the supports increase or decrease, thereby regulating the compensation forces from the correcting masses, which allows automating the process of compensation for moment and dynamic imbalance.
