Rapid Pace

This article deals with the problem of the digital revolution, which in recent decades has led to the rapid pace of innovation not only in the global industrial sector, but also in science, medicine, education and other areas of human activity, providing them with a significant increase in productivity, profitability, labor productivity, and safety for the environment. However, this has hardly affected the construction industry, which has not undergone significant changes over the past 50 years. This article reveals the content of the main reason for the extremely slow pace of innovative processes in construction, due to its global scale and decentralized nature. The construction industry accounts for approximately 6 % of global GDP (and for developing countries it reaches 8 % of GDP) and continues to grow. Special attention is paid to the fact that construction is the largest consumer of resources, which annually uses about 50 % of the total volume of steel produced and more than 3 billion tons of raw materials. Therefore, any innovation that leads, for example, to increased productivity in construction, on a global scale could save $100 billion a year. Also, this paper shows the factors that make construction a difficult business, which is not amenable to the necessary transformations. The article presents the basic principles of building an automated information support system.

While the construction industry consumes more raw materials than any other industrial sector, agriculture generates a large amount of waste that is not managed properly. The olive industry produces more than 7.5 million tons of waste that could be recovered. This paper presents a new method to valorize the leaves of olive tree pruning waste consisting of the manufacture of ecologic boards without adhesives by hot pressing. In order to analyze their influence, three manufacturing variables were varied to obtain the boards: leaf type (shredded and whole leaves), temperature (130, 140 and 150 °C) and time (4, and 12 min). Twenty-four boards were made and were then tested for their mechanical, physical and thermal properties according to the EN standards. The boards showed good results of thickness swelling (TS), water absorption (WA) and of thermal conductivity and can be used as an alternative for manufacturing thermal insulation boards. With a smaller particle size of shredded leaves, longer pressing times and higher pressing temperatures, the mechanical behavior of the boards could improve. The olive leaves are a low-cost renewable resource, and manufacturing products with a long, useful life can be beneficial to the environment.

The place and value of reserves for future expenses and payments in the enterprise capital are defined in this paper. Possibilities and expediency of providing certain types of expenses at the expense of pre-created reserves are considered. The specified definition of reserves as a component of the enterprise capital which are considered as reserved at the expense of additional owners contributions , profit, prime cost of the source for coverage of the future predicted or unpredicted expenses connected with maintenance of usual activity, its restructuring, distribution of expenses by the principles of prudence and compliance. It is proved that these principles are unreasonably removed by the latest legislation from the basic principles of accounting and financial reporting. Classification of reserves, the order of their formation and directions of their use are given in this paper. Reserves are classified into separate groups according to the sources of their formation, the directions of use, the obligation to create, the method of reflection in accounting and reporting, their participation in the enterprise capital. Particular attention is paid to the need of taking into account the hidden reserves. Their value is equal to the difference between the book value of the enterprise's property and its fair value. The order of recognition, documentation and reflection of accrual and use of reserves and other provisions in the accounting is specified. The following rrecommendations are given, on the one hand, to expand and deepen information in financial and other kinds of enterprise reporting concerning reserves as a component of enterprise capital, on the other - to simplify the accounting of reserved sources by additional unregistered contributions of participants, founders. The order of distribution and reflection in the accounting of reserves at withdrawal of separate participants from the company is specified. Recommendations concerning the recognition of accumulated resources for future liabilities by insurance reserves and their reflection in the composition of the enterprise own composition, making it possible to improve the economic performance, investment attractiveness of such entities are given.

Abstract Cellulose nanopapers provide diverse, strong and lightweight templates prepared entirely from sustainable raw materials, cellulose nanofibers (CNFs). Yet the strength of CNFs has not been fully capitalized in the resulting nanopapers and the relative influence of CNF strength, their bonding, and biological origin to nanopaper strength are unknown. Here, we show that basic principles from paper physics can be applied to CNF nanopapers to illuminate those relationships. Importantly, it appeared that ~ 200 MPa was the theoretical maximum for nanopapers with random fibril orientation. Furthermore, we demonstrate the contrast in tensile strength for nanopapers prepared from bacterial cellulose (BC) and wood-based nanofibrillated cellulose (NFC). Endemic amorphous polysaccharides (hemicelluloses) in NFC act as matrix in NFC nanopapers, strengthening the bonding between CNFs just like it improves the bonding between CNFs in the primary cell wall of plants. The conclusions apply to all composites containing non-woven fiber mats as reinforcement. Graphic abstract

Ferronickel Slag

In recent years, efforts to reduce greenhouse gas emissions have continued worldwide. In the construction industry, a large amount of CO2 is generated during the production of Portland cement, and various studies are being conducted to reduce the amount of cement and enable the use of cement substitutes. Ferronickel slag is a by-product generated by melting materials such as nickel ore and bituminous coal, which are used as raw materials to produce ferronickel at high temperatures. In this study, we investigated the fluidity, microhydration heat, compressive strength, drying shrinkage, and carbonation characteristics of a ternary cement mortar including ferronickel-slag powder and fly ash. According to the test results, the microhydration heat of the FA20FN00 sample was slightly higher than that of the FA00FN20 sample. The 28-day compressive strength of the FA20FN00 mix was approximately 39.6 MPa, which was higher than that of the other samples, whereas the compressive strength of the FA05FN15 mix including 15% of ferronickel-slag powder was approximately 11.6% lower than that of the FA20FN00 mix. The drying shrinkage of the FA20FN00 sample without ferronickel-slag powder was the highest after 56 days, whereas the FA00FN20 sample without fly ash showed the lowest shrinkage compared to the other mixes.

Introduction. The intensification of globalization processes that characterize the beginning of the new millennium has led to the emergence of supranational structures of regional and global scope. The deepening of Ukraine's integration into the international trading space causes new opportunities and threats. The relatively large size of the territory of Ukraine as a European state and its administrative structure causes a number of differences in the socio-economic development of its regions. Identifying regional differences in foreign trade in agri-food products and their causes is an urgent task of the study, given the leading role of the agro-industrial sector in Ukraine's foreign trade. The aim of the study is to identify regional differences of foreign trade in agri-food products and identify their causes. Results of work. The analysis results of foreign trade in agro-food products on the average for 2016-2018 by regions are given. It is determined that the four leading export regions are Mykolaiv, Odesa, Kyiv and Vinnytsia, as they account for about 47,9 %. The regions were evaluated according to the following indicators: the volume of regional exports, the volume of production of cereals and legumes, the production of sunflower seeds. According to the results of the analysis, each region was assigned a corresponding rank, on the basis of the values of which the correlation coefficients of the regions ranks were calculated. It is determined that there is a close link between the region's place in the national agri-food export ratings and the production of cereals and legumes; and there is a median link between the region's place in the national agri-food export and sunflower seed ratings. Imports of agro-food products by regions are considered, where Kiev region is the absolute leader, which together with Odessa, Lviv and Dnipropetrovsk regions have 64.5 % of all corresponding imports. The analysis of agro-food products import by groups of goods is presented. The regions ranking by import volumes of agri-food products and disposable income per person has been done. The obtained coefficient of correlation of ranks testifies to the average degree of relation close to high. Conclusions. It is proved that the differences in the volumes of crop production mainly cereals, legumes and sunflower are the basis for regional differentiation of agricultural food exports, which testifies to the raw nature of exports, stagnation of livestock and unsatisfactory development of the domestic food industry. Differentiation of imports of agro-industrial products is caused by the difference in income of the population by regions.
