Published: February 2020

Nowadays, in order to ensure the efficiency of manufacturing of internal carving in hard-working materials, advanced German companies use high-speed steel HSS, HSS-E, PM HSS-E with a new chemical composition. Sometimes wear-resistant coatings are used to reduce the frictional forces and improve the cutting properties of the tool.
The article analyzes the influence of chemical-thermal treatment for domestic instrumental steels: P18; P12; P9; P6M5; R6M3.
The various methods of chemical-thermal treatment of the tool provide, although in varying degrees, the increasе of stability of the cutting tool, and the information with regard to non-sticking taps is contradictory.
Therefore, in order to achieve a positive result, it is necessary to conduct further scientific research on the influence of technological indicators on the process of making internal carving by brushless taps after the chemical-thermal processing of the tool.

Published: February 2020

In assessing marginal change in the process of metal forming, plasticity is significantly affected by the rate of damage accumulation and their healing as derivatives of the stress state indicators. It is shown that under complex loading conditions, when the damage accumulation rate (the first derivative of the stress state indicators) is more than 5 and the curvature of the material deformation trajectories (the second derivative of the stress state indicators) is greater than 1, the scalar integral criteria give the most reliable results destruction, taking into account the influence of the history of deformation on plasticity.
SOLUTION OF THE EQUATION OF IMPACT THE ELASTIC BODY, ONE OF WHICH CONE
Authors: Olshanskiy Vasyl , Olshanskiy Stanislav
Published: February 2020

The impact interaction of elastic bodies with a small initial velocity is considered, when one of them is limited in the contact zone with another conical surface of revolution. Using the well-known solution of the static contact problem of the theory of elasticity, which found I. Shtaermann, and the assumptions of G. Hertz, which he made when creating his own theory of quasistatic impact of solids, compiled a nonlinear differential equation of impact force as a function of time. His closed analytical solution, which describes the process of dynamic interaction of bodies in time, is expressed through the periodic Ateb-sine. To simplify the use of the obtained analytical solution in the calculations, a separate table of the specified special function has been compiled and its approximation with elementary functions has been proposed, the relative error of which is less than one percent. In order to confirm the reliability of the constructed solutions, the integration of the equation of impact force on the computer was carried out in parallel. A good agreement is established between the results obtained by the constructed analytical solution and the numerical integration of the nonlinear Cauchy problem on a computer for a second-order differential equation. Compact formulas for the maxima of the impact force and the magnitude of the compression of bodies, as well as the formula for the duration of the impact process are derived. It is noted that the obtained results can be used in determining the dynamic loads acting on the rubber-lined rolls of the vibration classifier when pieces of solid raw materials fall on them. Examples of calculations are given and a comparative analysis of the results is carried out.
THE PRODUCTIVITY AND COMPETITIVENESS PROBLEMS OF LATVIA IN THE CONTEXT OF THE GLOBAL ECONOM
Authors: JEKABSONE Sandra
Published: February 2020

In the article the dynamics of labour productivity in Latvia was analyzed and the factors which have influenced the labour productivity in last 5 years were detected, to compare the productivity in Latvia with EU average. Analysing changes in productivity and labour costs in Latvia from 2013 till 2017, we can see that growth of labour costs exceeds the growth of productivity by more than 2 times in both, tradable sector and total economy. Slow growth in productivity compared with the labour and other production expenses lead to an increase in the price of final goods and services, which negatively corresponds with producers’ competitiveness in both internal and external market. Also, the attention is focused on how to increase productivity growth potential and improve the competitiveness of Latvia. One of the main challenges for Latvia is the creation of new competitive advantages that are associated with investments in the latest technologies, innovation, research, human capital, efficient allocation of resources and redistribution that comes with the behavioural changes of economic subjects. The main conclusion of the research shows, that two mutually interconnected processes determine increase of productivity level. First, they are the entrepreneurs’ choices about competitive advantages on which their business strategies are based, which define the business management and technological decisions (to modernize production or to move resources across sectors, to other region or even other country). Second, it is the ability of the country to ensure the reallocation of its resources to the most productive firms and sectors, i.e. to promote structural reforms or “technological upgrading”.

Authors: Fedirko P. P. , Krol V. O. , Bonchyk V. S.
Published: February 2020

The article presents the study results of the anaerobic materials effect on the strength of threaded connections in the repair of machinery and equipment. Their use is the simplest, most economical and reliable method of fixing and restoring threaded connections. The basis of the anaerobic compositions is polymerization compounds of the acrylic series, most often dimethacrylic and polyalkylene glycol ethers, which are characterized by a high conversion rate into spatially cross-linked polymers. Unlike mechanical methods of fixation and recovery, anaerobic materials completely fill the space between the threads of the spiral. This significantly increases the friction between the parts of the connection, improves the protection of the metal of the interface against corrosion, increases the torque when unscrewing in relation to the tightening torque, increases the resistance of the connection to the action of vibration, shock, shock loads. For the research, anaerobic thread locks were purchased, which were tested according to the same procedure and, after 24 hours at room temperature, each connection was clamped in a vice in turn so that the head of the torque wrench captures only the top nut, which had to be unscrewed. The rate of hardening of anaerobic adhesives is influenced by the size of the gaps between the combined surfaces, temperature, cleaning quality, the nature of the coating, etc. It has been established that the presence of polymerized anaerobic materials in the contact zone of parts significantly increases the strength of the joints. The conducted studies allowed to verify in practice the conformity of the tested anaerobic clamps of threaded connections to the stated parameters, to delineate the scope of their application. So, anaerobic adhesives for fixing threaded connections allow you to fix screws, nuts, bolts and pins to protect against loosening and loosening due to vibration

Published: February 2020

The article deals with the essence of the accounting process at dairy processing enterprises. It is determined that the development of Ukrainian agriculture should be carried out on an innovative basis. Innovation in agriculture comprises the improvement of technologies, changes in technology, ecology, economics, etc. It is proved that the accounting and the calculation process at the milk processing enterprises are complex and multifaceted. It was mentioned that in a market-oriented economy, the existing system of inventories accounting cannot meet the information needs of managers, since it has a number of shortcomings, namely: there is no integration of all types of accounting to provide managers with the necessary information; data on deviations of actual indicators from normative ones are not daily displayed, therefore, they are not used in production management; the control of the use of inventories is limited by the retrospective control of the actual cost price, when losses and overexpenditure cannot be changed; the system of accounting and assessment of return waste does not contribute to their rational use and distorts data on the cost of production. It has been found out that the initial internal documentation at the enterprises of the industry needs to be improved in order to ensure the accuracy of expenses accounting and calculation of the cost price of dairy products of own production. Changes to the forms of the Journal of the Milk Yield Accounting have been introduced, which will facilitate the establishment of document circulation and speeding up the movement of dairy products between producers and purveying enterprises The main directions of improvement of the competitiveness of products are defined: creation of environmentally friendly products, improvement of taste qualities of dairy products, production of dietary goods and goods for patients with diabetes, increase of the share of non-fat and skimmed products, reduction of food preservative content, introduction of non-traditional types of dairy products with new consumer properties. It is concluded that the issue of accounting development and ways of its improvement at dairy processing enterprises is multifaceted and remains unsolved

Published: February 2020

In spite of the proposal of the International Integrated Reporting Council (IIRC) in 2013 on the structure of the integrated report, the question of the principles of its formation and the concept of integrated reporting in Ukraine remains open. The issue of trust in society and among stakeholders, based on Sztompka’s theory, is extremely relevant in the post-industrial economy. Consequently, our study is devoted to the analysis of the definitions of the concept "integrated reporting", its formation principles and conceptual bases of development in Ukraine. The research was conducted using a comparative analysis of scientific literature, questionnaires and surveys of 42 accountants of 10 enterprises of Khmelnitsky region, conceptual analysis, categorical and systemic approaches. The definitions of the concept of "integrated reporting" are systematized, the principles of its preparation are generalized. According to the results of the research, the authors consider the integrated reporting as a new paradigm of corporate reporting which provides information about the key factors for creating value at the moment and in the future through the presentation of financial and non-financial indicators in order to create a stable, functioning business. The main advantages and disadvantages of its formation in the Ukrainian institutional environment are highlighted. The conducted research reveals the absence of the regulating and methodological tools for the formation of integrated reporting in Ukraine, due to the availability of different types of reports and lack of understanding of their purpose. Through conceptual analysis, the conceptual bases of integrated reporting are generalized and systematized in accordance with international standards

Published: February 2020

To reduce energy costs and improve the quality of granular materials mixing, a number of original constructions of spiral mixers with screw working body has been developed. Screw mechanisms are frequently used in all sectors of the economy due to the concentration of the various operations in connection with transportation on the inclined surfaces of machines and mechanisms. However, the application of these constructions needs to consider issues related to the calculation of the loads on the screw working body and motion state, as well as appropriateness of their use. Research study deals with the calculation of the motion state of the selected volume on inclined high speed screw conveyor. The authors examined the work of inclined screw conveyor, which includes screw working body with constant parameters. According to the contact of selected volume of cargo with the screw surface and the cylindrical surface of the shroud, its placement is determined by the radial parameter R and angular parameter θ. On the basis of the method of graphical analysis we propose the method for determination of the average angular velocity of the selected volume by extreme value, that is identified by the mathematical rigor and simplicity of implementation. The limit deviations of particles velocities in transportation and withdraw of the analytical dependence are determined. It is proved that it leads to the intensive mixing of cargo and efficient mixing at the boundary conditions. The analytical dependences for determination of the angular and axial velocity of particles on sloping surfaces are given in the study. The process of transportation and mixing of bulk cargo is explored and it is proved that fluctuations in the speed of transportation of cargo, which improves the mixing conditions of bulk cargoes, take place when we use crews with axial motion

Published: February 2020

The study is devoted to the analysis of the influence of four primary processing and fertilizer systems on the change in the number of lumbricides in the arable layer of typical black soil and the productivity of field grain-sowing crop rotation.
The study material was the amount of lumbricides in the arable layer of black soil and their distribution depending on the main processing and fertilizer systems. The research methodology is based on experimental data obtained during 2016-2018 with a two-factor stationary field experiment, established in 2006 on the experimental field of the Belotserkovsky NAU.
The highest amount of lumbricides in soil layers of 0-10, 20-30 and 0-30 cm is established under differential tillage, that is correspondently 39,3, 5,3 and 61,9 examples per square meter. It is 27,2, 20,5 and 24,0 percent more than on the watch list. Under poweredless and disc tillage there were correspondently 61,1 and 60,0 examples of lumbricides per square meter in a plow layer, so the results were close to powered-powerdless tillage.
The decrease of the lumbricides population is observed during a crop vegetation. The biggest decrease in their number in a plow layer is established under powered tillage, that is 58,0%, and the smallest decrease is observed under poweredless tillage – 54,4 %. Under a disc and differential tillage such decrease was correspondently 55,0 and 56,0 %.
The exact principles of lumbricides distribution in different parts of a plow layer under different main tillage systems are not established. Only a small increase in their number could be seen in a soil layer of 0-10 cm under poweredless and differential tillage and a decrease was observed under a disc tillage in comparison with the powered one. Thus, from the general number in a plow layer the amount of lumbricides in soil layers of 0-10, 10-20 and 20-30 cm was correspondently: under a powered tillage – 61,9; 29,3 and 8,8%, a poweredless tillage – 63,0; 29,6 and 7,4 %, a powered-poweredless tillage - 63,5; 28,1 and 8,4 %, a disc tillage – 60,0; 31,8 and 8,2 %.
After the first, the second and the third levels of fertilization the number of lumbricides population was increasing correspondently 1,56, 2,07 and 2,32 times in comparison with the unfertilized areas.

Published: February 2020

El presente trabajo da a conocer nuevos hallazgos arqueológicos en la provincia de Entre Ríos vinculados al poblamiento inicial americano. Se presentan tres artefactos líticos, dos puntas de proyectil y una piedra discoidal. Los hallazgos fueron realizados en distintos contextos; las puntas mediante tareas de prospección en el departamento Villaguay y el lito discoidal a partir de un trabajo sobre colecciones en el departamento Gualeguaychú. Estos hallazgos manifiestan la importancia potencial de la región en relación a la ocupación humana temprana, como ocurre en áreas circundantes donde las evidencias arqueológicas son abundantes.
“Estudios arqueobotánicos en Argentina. Situación actual y nuevas perspectivas”
Authors: López M. Laura , Andreoni2 Diego
Published: February 2020

El estudio de los restos botánicos recuperados en los sitios arqueológicos emplazados en toda Argentina posee una larga historia, cuyo máximo exponencial se inició hacia la década de 1990. A partir de este momento comenzaron a realizarse estudios sistemáticos. Reseñas ya elaboradas sobre el desarrollo de la Arqueobotánica y Paleoetnobotánica en nuestro país (Capparelli y Lema 2010; Capparelli et al. 2001) y en su contexto sudamericano (Archila et al. 2008; Planella y Capparelli 2015; Rossen 2015) han demostrado el camino recorrido tanto metodológico como teórico. Aquellos primeros investigadores provenientes de la botánica como de la agronomía y quienes ayudaron a los arqueólogos de principios del siglo XX a identificar los vegetales en diferentes contextos espacio-temporales, dieron lugar al surgimiento de equipos de trabajo dedicados a desentrañar problemáticas acordes a la relación hombre-planta en el pasado o a interpretar el papel jugado por las plantas en las prácticas sociales y políticas pretéritas. Numerosas técnicas específicas se han desarrollado para la recuperación y el análisis del material macroscópico y microscópico de diferentes órganos vegetales, en distintas condiciones de preservación (carbonizados/ desecados) y con variadas cronologías a lo largo del Holoceno. A su vez, diversas temáticas fueron incluidas en los proyectos de investigación, que involucraron no solo el análisis sobre el material vegetal propiamente dicho, sino también estudios etnobotánicos de campo y bibliográficos que permitieron ampliar la perspectivas de interpretación de las prácticas pretéritas de las cuales los vegetales formaron parte.
La Paleoetnobotánica del Centro-Este de Argentina: desarrollo y enfoques.
Authors: Colobig María , Zucol Alejandro , Brea Mariana
Published: February 2020

En este trabajo se sintetizan los avances en Paleoetnobotánica en el Centro-Este de Argentina. Se presentan diversos tipos de muestras, tanto microrrestos (biosilíceos y almidonosos) y macrorrestos (antracológicos y carpológicos), extraídas de diversos soportes como material sedimentario y artefactos arqueológicos. Los estudios realizados en el área de distribución contribuyeron a identificar los diferentes usos de los recursos vegetales en los niveles de ocupación sucesivos, a partir de la transición Pleistoceno-Holoceno hasta finales del Holoceno, y a sectorizar microambientes dentro de las cuevas estudiadas en las sierras de Tandilia oriental. En la región costera, los sitios están fechados durante el Holoceno tardío y se sitúan principalmente en elevaciones incrementadas en muchos casos por la acción humana. Los estudios de múltiples indicadores botánicos en estos espacios permitieron obtener nueva información sobre los recursos silvestres y domésticos y también caracterizar aspectos ambientales de las ocupaciones e identificar los recursos en determinados sectores de los sitios. En suma, estos estudios han proporcionado evidencia directa de la vegetación en los sitios arqueológicos.
El árbol que da frutos, se corta y se echa al fuego. Discusiones sobre el uso de la leña en la Mendoza colonial.
Authors: Mafferra Luis , Chiavazza Horacio , Roig Juñent Fide
Published: February 2020

En la presente contribución se presentan los resultados obtenidos del análisis de carbones arqueológicos asociados al período colonial (siglos XVI al XVIII) y recuperados en el sitio Ciudad de Mendoza, específicamente en los contextos Ruinas de San Francisco, Alberdi e Ituzaingó y Edificio Plaza Huarpe. En este trabajo, nos interesa discutir la identificación de restos de carbón de especies leñosas exóticas, tanto de frutales como duraznero (Prunus aff. persica), membrillero, manzano o peral (Aff. Cydonia/Malus/Pyrus) o vid (Vitis vinifera); como de otros árboles como el guayacán (Caesalpinia paraguariensis) o el tamarindo (Tamarix gallica). Analizaremos la importancia del uso, desde momentos tempranos, de algunas de estas maderas como combustible en el contexto de la no aprehensión del paisaje nativo y de la integración de la colecta de leña dentro de las actividades cotidianas de la sociedad colonial. Propondremos ante lo mismo, una vinculación más amplia de la esperada con los frutales exóticos, ya que con anterioridad su introducción se asociaba, en general, sólo a la importancia de sus frutos como alimento. A la vez, analizaremos la recolección de leña por fuera de lo extractivo y dentro de prácticas que probablemente implicaron también el cuidado de estos árboles introducidos.
“Estado actual de los estudios bioantropólogicos con muestras prehistóricas e históricas de restos óseos humanos: el caso de estudio de los Andes Meridionales”
Authors: Menendez Lumila , Mansegosa Daniela
Published: February 2020

Los Andes Meridionales, formados hacia el este por el Centro-Oeste de Argentina y hacia el oeste por el centro de Chile, constituyen una región donde se han desarrollado prolíferas investigaciones sobre las poblaciones prehistóricas e históricas que las habitaron. En un comienzo estas investigaciones fueron realizadas de forma aislada, pero desde mediados de siglo XX, y con mayor énfasis a partir de la década del ´90, diversos equipos de investigación llevan adelante estudios arqueológicos de manera sistemática. Han sido múltiples los temas abordados, los cuales fueron previamente analizados y sintetizados (Aspillaga y Arriaza 2011; Novellino et al. 2014; Rothammer y Llop 2004): la identidad de los grupos humanos que habitaron la región, sus características y relaciones con grupos de otras regiones, la interacción de tales grupos con sus ambientes, patrones de subsistencia y movilidad, la integración de procesos evolutivos para explicar la diversificación de dichas poblaciones, y más recientemente el estudio de los modos de vida de grupos prehistóricos e históricos en la región.
El registro faunístico del sitio Negro Muerto 3 (provincia de Río Negro): tafonomía y patrones de explotación.
Authors: Mange Emiliano , Prates Luciano , González Venanzi Lucio , Di Lorenzo Maitén
Published: February 2020

En el sitio arqueológico Negro Muerto 3, ubicado en el valle medio del río Negro, se recuperaron entierros humanos y diversos materiales (artefactos líticos, fragmentos de cerámica y restos faunísticos). El sitio fue interpretado como un área de uso residencial y mortuorio, ocupada durante el Holoceno tardío. En este trabajo se presentan los resultados del análisis de los materiales faunísticos, que incluyen valvas de moluscos, cáscaras de huevos y elementos óseos (de peces, reptiles, aves y mamíferos). El análisis muestra que el conjunto es de origen principalmente antrópico y que una parte importante de los restos fue ingresada para su consumo. Las evidencias de dinámica postdepositacional muestran escasa exposición superficial de los materiales, y una incidencia importante de precipitación de carbonato y raíces. Si bien las características generales del sitio sugieren un patrón de explotación de la fauna similar al de otros sitios de la región con cronologías cercanas (alta diversidad de especies de pequeño porte, propias del ambiente de valle), se señalan algunas diferencias. La nueva información generada en el trabajo es integrada a los modelos desarrollados previamente y, a partir de esto, se plantean nuevos interrogantes e hipótesis sobre los patrones de explotación de los recursos faunísticos.
