The Challenge of Strength Grading UK Hardwoods
Authors: Cramer Marlene
Published: December 2023

Recent research in Europe is bringing a wider range of wood species to the construction market as structural timber and glue laminated products. This option would also open markets for currently underused UK species, foremost hardwoods, but testing efforts when developing strength grading assignments for any minor UK species are prohibitive, as the resource is small and scattered. Grading approaches that require less material for destructive testing could be employed to open routes to market for structural hardwood products. In addition, the European hardwood research has revealed some gaps and uncertainties in grading standards. In particular, data are lacking to support adjustment equations for size, moisture content, and testing arrangement for hardwoods. This paper outlines a new PhD project that will focus on these problems and aims to develop an easier route for strength grading hardwoods.

This paper presents an approach for computing the heat balance of boiling pits during the plasticizing of non-frozen logs intended for the production of peeled veneer. With the help of our non-stationary model, the heating times of beech logs with a diameter of 0.4 m, an initial temperature of 10°C, and a moisture content of 0.6 kg∙kg-1 were determined at water temperatures in the pit equal to 70, 80, and 90°C. Using the determined logs’ boiling durations and the mentioned approach, the change in the total energy required to carry out the entire boiling process and that required for each of the individual components of the heat balance was calculated. Computer simulations were conducted for a concrete pit with overall dimensions of 8.0 × 2.6 x 2.5 m, a working volume of 20 m3, and a degree of filling with logs equal to 45, 60, and 75%. It was found that the increase in the water temperature from 70 to 90°C causes an increase in the total specific energy, as well as in the energy for the heating of the logs themselves, the construction, and the water of the pit. At the same time, the energy required to cover the heat losses of the pit decreases and the energy for heating the metal heater/radiator itself does not change. A decrease in the degree of filling of the pit with logs from 75 to 45% causes an increase in both the total energy and all its components except the energy for heating the logs, which remains unchanged.
Influence of Density on the Withdrawal Staple Strength from Hemp Shive Panels

Published: December 2023

Particleboards are the main material used in the production of furniture and furnishings. The shortage of wood raw material and the everincreasing amount of particleboards produced suggest a search for alternative raw material sources for this panel type. On the other hand, significant quantities of agro-industrial lignocellulosic residues are available worldwide. Such a type of residue is hemp shives. Basic joints in furniture frames are stapled joints, as it should be said that density is the main characteristic of particleboards, and their other properties strongly correlate with it. The present research studies the influence of the density of panels from hemp shives on their staple withdrawal resistance. For this purpose, panels from hemp shives with melamine-formaldehyde (MF) resin as an adhesive and densities from 600 kg.m-3 to 900 kg.m-3 were produced in laboratory conditions. The density of the panels varied with a step of 100 kg.m-3. As a result of the research, it was found that the staple withdrawal resistance of hemp shives particleboards from the edge and side of the panels increases almost twice with the increase of their density. It was also found that, unlike industrial particleboards, edge staple withdrawal resistance is higher in hemp shive panels than side staple withdrawal resistance. Laboratory-produced panels from hemp shives have a higher staple withdrawal resistance at similar densities than industrial particleboards. However, this is at the expense of using expensive MF resin and the significantly extended press factor. The main novelty of the research is the establishment of the effect of the density of hemp shive particleboards on their staple withdrawal resistance, as well as the demonstration of the possibility of producing panels from an alternative lignocellulosic raw material with a better staple withdrawal resistance than that of industrial particleboards manufactured from wood raw material.

Published: December 2023

Computer Numerical Control (CNC) machines are increasingly popular in the production of furniture and wood products, because they combine high processing quality with short production time. The effective use of CNC machines depends on the processing parameters, which also affects the quality of the processed surface. The aim of this study was to determine the effect of feed rate, cutting direction, and grain direction on the surface roughness of various types of wood. Three European wood species (oak, beech, fir) were cut with a spindle speed of 16,000 rpm and two different feed rates (5,000 and 10,000 mm/min) using end mill tools on the CNC machine. The milling was performed in two cutting directions (radial and tangential) and two grain orientations (0° and 90°). An analysis of variance (ANOVA) was performed to evaluate the impact of the cutting parameters. The surface roughness measurements were taken, and two surface roughness parameters (Ra and Rz) were measured to determine the surface quality of the wood. According to the results of this study, the lowest surface roughness values, milling with the same processing parameters, occurred for oak wood, while the highest values occurred for fir.

Adapun perbandingan pemanfaaatan koleksi local content dapat di lihat dari segi berikut, a) secara umum kebutuhan informasi saat masa pandemi Covid-19 dan new normal  mahasiswa tahap akhir tetap tinggi, dengan masih banyaknya pemustaka yang mencoba untuk memanfaatkan koleksi local content secara langsung melalui kegiatan membaca, mencatat dan menduplikasi koleksi-koleksi tersebut. Akan tetapi, penutupan layanan perpustakaan dan mengalihankan ke layanan daring. Sedangkan new normal, pemustaka sudah dapat mengakses informasi secara langsung ke perpustakaan. b) Motif, dimasa pandemi dan new normal tindakan/ motif mahasiswa tahap akhir dalam mencari informasi hampir sama. c) Minat, dilihat dari kunjungan, mahasiswa tahap akhir memiliki kecenderungan yang kuat dalam pemanfataan koleksi local content skripsi  akan tetapi dimasa pandemi terjadi penutupan layanan. Sedangkan di era new normal antusias kunjungan meningkat serta perbedaan kebutuhan informasi yang dibutuhkan dengan koleksi yang ada di perpustakaan. Diharapkan perpustakaan lantai dua ruangan karya ilmiah atau local content agar shelving koleksi skripsi lebih rapi dan menyesuaikan koleksi skripsi sesuai fakultas, menambah jumlah dan variasi koleksi digital local content dan sarana penelusurannya
A Bike System for All in Silicon Valley: Equity Assessment of Bike Infrastructure in San José, CA
Authors:   San Jose State University, Zandiatashbar Ahoura , Albrecht Jochen , Nixon Hilary
Published: December 2023

Investing in sustainable, multimodal infrastructure is of increasing importance throughout the United States and worldwide. Cities are increasingly making strategic capital investment decisions about bicycle infrastructure—decisions that need planning efforts that accurately assess the equity aspects of developments, achieve equitable distribution of infrastructures, and draw upon accurate assessment methods. Toward these efforts, this project uses a granular bike network dataset with statistical and geospatial analyses to quantify a bike infrastructure availability score (i.e., bike score) that accounts for the safety and comfort differences in bike path classes in San José, California. San José is the 10th largest U.S. city and a growing tech hub with a booming economy, factors that correlate with increased traffic congestion if adequate multimodal and active transportation infrastructure are not in place. Therefore, San José has been keen on becoming “one of the most bike-friendly communities in North America.” The City’s new plan, which builds on its first bike plan adopted in 2009, envisions a 557-mile network of allages-and-abilities bikeways to support a 20% bicycle mode split (i.e., 20% of all trips to be made by bike) by 2050. Hence, San José makes a perfect study area for piloting this project’s methodology for accurately assessing the equity of urban bike plans and infrastructures. The project uses the above-mentioned bike score (representing the bike infrastructure supply status) and San José residents’ bike travel patterns (to show bike trip demand status) utilizing StreetLight data to answer the following questions: (1) Where are San José's best (bike paradise) and worst (bike desert) regions for cycling? (2) How different are the socioeconomic attributes of San José’s bike desert and paradise residents? (3) Has San José succeeded in achieving an equitable infrastructure distribution and, if so, to what extent? And, (4) has the availability of infrastructure attracted riders from underserved communities and, if so, to what extent? Using the bike infrastructure availability score, this research measures and maps the City of San José's best and worst regions for cycling through geospatial analyses to answer Question 1 above. Further spatial and statistical analyses including t-tests, Pairwise Pearson correlation analysis, descriptive analysis, spatial visualization, principal component analysis (PCA), and multiple regression models to answer Questions 2, 3, and 4. In addition to this report, the findings are used to develop an open access web-tool, the San José Bike Equity Web Map (SJ-BE iMap). This research contributes to the critical assessment and planning efforts of sustainable, multimodal infrastructure in California and beyond.
Should State Land in Southern California Be Allocated to Warehousing Goods or Housing People? Analyzing Transportation, Climate, and Unintended Consequences of Supply Chain Solutions

Published: December 2023

In response to COVID-19 pandemic supply chain issues, the State of California issued Executive Order (EO) N-19-21 to use state land to increase warehousing capacity. This highlights a land-use paradox between economic and environmental goals: adding warehouse capacity increases climate pollution and traffic congestion around the ports and warehouses, while there is a deficit of affordable housing and high homeless rates in port-adjacent underserved communities. This study aims to inform regional policymakers and community stakeholders about these trade-offs by identifying current and future supply of and demand for warehousing and housing in Southern California through 2040. The study uses statistical analysis and forecasting, and evaluates across numerous scenarios the environmental impact of meeting demand for both with the Community LINE Source Model. Warehousing and housing are currently projected to be in high demand across Southern California in future decades, despite short-run adjustments in the post-pandemic period of inflation and net declines in population. Using state land for warehousing creates environmental justice concerns, as the number of air pollution hotspots increases even with electrifying trucking fleets, especially when compared against low-impact affordable housing developments. However, low-income housing demand appears to be positively correlated with unemployment, suggesting that the jobs provided by warehousing development might help to ameliorate that concern.
The Many Facets of Trust
Authors: Baratella Riccardo , Amaral Glenda , Sales Tiago Prince , Guizzardi Renata , Guizzardi Giancarlo
Published: December 2023

Trust is an attitude that an agent (the trustor) has toward an entity (the trustee), such that the trustor counts upon the trustee to act in a way that is beneficial w.r.t. to the trustor’s goals. The notion of trust is relevantly discussed both in information science and philosophy. Unfortunately, we still lack a satisfying account for this concept. The goal of this article is to contribute to filling this gap. First, we take issue with some central tenets shared by the main philosophical accounts, such as that there is just one relation of trust, that this relation has three argument places, and that trust is reliance plus some extra factor. Second, we provide a novel account of trust, also discussing different levels of trust. According to the account we put forth here, the logical form of trust sentences is expressed by a four-place relation. Further, we distinguish and characterize four kinds of trust relations and their connections. We also argue that trust and reliance are different phenomena. Third, on the basis of the proposed account, we extend the Reference Ontology of Trust (ROT). We call the new version of ROT that includes this extension “ROT 3.0”. Finally, we discuss the implications of the new ontological definitions in the applications we have done of the concept of trust in other works, also pointing out future applications made possible by these novel accounts of trust.
Ontology-Driven Multi-Level Conceptual Modeling for Dataset and Distributions Descriptions
Authors: Borges Vânia , Prata Eduardo M. , Campos Maria Luiza M.
Published: December 2023

This paper presents an improvement proposal for an ontology-driven multi-level conceptual model for the data catalogue domain. Data catalogues gather metadata that describe resources in different and heterogeneous digital platforms (repositories). They are supported by Information Systems (IS) that use these descriptors to provide visibility and support resources exploration and analysis. Domain ontologies are essential to promote quality ISs, as they are developed to reflect the intended reality. The proposed conceptual model is well-founded on the Unified Foundational Ontology and the Multi-Level Theory, based on the widely used DCAT vocabulary, a standardized metadata schema for describing datasets and data services. The resulting model addresses ambiguities and contemplates high-level types contributing to the conformance of domain concepts and relationships. In addition, they provide knowledge about the different types of resource descriptors and relationships contained in a specific catalogue, favoring its management. The paper enhances the previous model by extending it to handle descriptors representing a dataset according to the data equivalence across multiple distributions. We also demonstrate the model by describing a dataset with no data equivalence in its distributions, taken from a real-world scenario, thus providing a structured representation to manage metadata sets in the data catalogue domain.

Basics of formalization of factors affecting the technology of restoration of building structures
Authors: Osipov О. F. , Osipov S. О.
Published: December 2023

Currently, the priority direction of the technological development of the construction industry of Ukraine is the improvement of methods of restoration of construction structures and structures that have undergone destruction of varying degrees of intensity. The effectiveness of restoration technologies, along with the existing methods of performing works and mechanization of restoration processes, largely depends on the level of formalization of factors that affect the parameters of their restoration technology, taking into account the properties of restoration objects and the systemic property of the building as a complex structural system.

The article describes the decomposition of the problem, the main principles and the adopted concept, which are the basis of the methodology of formalization of factors affecting the technology of restoration of damaged building structures during the restoration of destroyed buildings and structures, as well as in the conditions of reconstruction of buildings and restoration of architectural monuments. The formalization of influencing factors is based on the idea of patterns of interaction of restorative processes with the external environment, as a set of external factors that influence the process of transforming material elements into construction products.

For the mathematical formalization of the problem of efficiency research, it is necessary to have numerical values of the coordinates, as which the values of factors and parameters are accepted (when solving the optimization problem at a detailed level) or the weighting factors or their estimates are accepted based on the results of previous studies and analysis of representative objects ( a priori information – when solving the optimization problem at the system level). The parameterization of influencing factors is based on idealizations - the construction of theoretical models, which are subsequently subject to formalization of one or another kind. Complexity categories are formed as a certain combination of the main features that describe, respectively, the characteristic construction and technological characteristics of the restoration object (reconstruction, restoration or destroyed object), the conditions of work production and the structural and technological parameters of the work front
Development and reform of state housing programs in Ukraine.
Authors: Zeltser Y.
Published: December 2023

The need to provide the citizens of Ukraine with housing has become acute since Ukraine  gained independence. The existing Soviet system of providing housing to citizens was broken, and the new system was never built.

There are several categories of citizens who are legally entitled to free housing from the state. Also, some categories of citizens have the right to service apartments, which are provided to citizens temporarily. However, further privatization of such apartments in an automatic mode is not provided for by law. State housing programs provide assistance in obtaining housing for the rest of the citizens who do not have the right to receive housing free of charge.

In 2020-2021, the Government of Ukraine and the National Bank of Ukraine did not implement the Presidential initiatives to significantly increase the volume of housing provision, including the introduction of effective mortgage and leasing financial instruments.

Currently, state housing programs in Ukraine existed and exist only at the stage of pilot projects. Thus, according to the new state housing program "Homes in Action", in general, the state issued only 784 loans to Ukrainians in the amount of 1 billion 5.4 million hryvnias.

In the period since the beginning of the full-scale war of russia against Ukraine, the problem of providing housing to citizens has become even more urgent. Damages from the destruction of the housing stock are estimated at $54 billion. In December, this amount increased by another $1.5 billion. Over ten months of war, a total of 149,300 residential buildings were damaged or destroyed.

Thus, it is clearly premature to talk about the solution to the issue of housing for the citizens of Ukraine at the present time.

It is clear that State housing programs in Ukraine need further development and reform. For this, first of all, institutional support for the development and reform of state housing programs in Ukraine is necessary, which is one of the leading and relevant directions of the development of modern economic science and practice.

In order to solve this issue, it is necessary to complete a number of tasks listed in this article, which will make a significant contribution to the successful reform of state housing programs in Ukraine in the conditions of the country's reconstruction after the end of the full-scale war with russia..
Modern approaches to registration and simplified system of taxation of natural persons-entrepreneurs.
Authors: Chernyavska Yu.B , Zinchenko M.M.
Published: December 2023

Modern challenges in the conditions of war and pandemic require a quick response in the economic sphere, since it is the foundation that holds the military front. And therefore, stopping the economy will "bleed" the already extremely depleted budget. The task of the state is to prevent enterprises from stopping, as well as to stimulate small business, which has always been a powerful source of filling the state treasury.

The purpose of the study is to simplify the registration, management and taxation of small businesses, including construction, as much as possible.

The article analyzes the new changes in the Tax Code of Ukraine (Tax Code of Ukraine) taking into account the simplified system of taxation of individual entrepreneurs. The main advantages of legal business conduct are identified, various options for its registration (including remote) are shown, new possible options for generating an electronic signature are presented, the issue of business legalization without registration of a sole proprietorship and those who can take advantage of such an opportunity is considered, and what changes are subject to sole proprietorship payers 1-3 groups of the unified tax in 2023, the peculiarities of their document flow and taxation during the period of martial law, given specific advice on filling out declarations by entrepreneurs; a number of errors for which FPOs deprive the payer of the single tax, as well as typical errors of self-registration of FPOs, are defined; an alternative approach to the preferential taxation system for the construction business has been revealed, which will make it possible to take advantage of the simplified taxation system. Several points have been highlighted to improve the requirements for taxpayers of the 1-3 groups of the single tax by the state (in particular, adequate consideration of the inflation factor), a number of encouraging steps have been revealed from power structures to starting your own business.

The issue of digitization and development of modern electronic services for taxpayers was also on the agenda. Today, digitization is considered a necessary factor for the functioning of public enterprises. This procedure should become simple, understandable, convenient, easy and familiar in application for any average citizen of Ukraine. And such a transformation is possible thanks to the implementation of the e-cabinet in the taxpayer's profile.

Published: December 2023

The article examines the genesis of the concept of "sustainable development" and its influence on the sustainable development of intellectual capital. It was determined that the development of intellectual capital contributes to the realization of all the Sustainable Development Goals (SDGs), providing the necessary knowledge, skills, innovations and opportunities to solve the world's most pressing sustainable development problems. Intellectual capital is a valuable resource for promoting economic, social and environmental progress, comprehensively balanced development of society. Intellectual capital plays a key role in achieving both individual targets and the overall SDGs by 2030.

The study of the impact of intellectual capital on the achievement of the Sustainable Development Goals is of great relevance and importance, as it provides valuable information on how human knowledge, skills and experience can be used to address complex, interconnected global challenges. Understanding this relationship allows us to develop more effective strategies and actions to promote sustainable development and create a better future for all.

As a result of the analysis, it was found that the implementation of all seventeen Sustainable Development Goals depends on the influence of intellectual capital. At the same time, the so-called "spiral effect" arises, when the development of intellectual capital will contribute to the achievement of such goals as gender equality, decent work and economic growth, quality education, poverty alleviation, development of industry, innovation and infrastructure, reduction of inequality, sustainable development of cities and communities , in turn, the achievement of these goals will create favorable conditions for the growth of intellectual capital, becoming an impetus for its further development. Such an approach to the description of progressive growth not only corresponds to the principles of comprehensively balanced development, but will also allow creating a model of the influence of the components of intellectual capital on the development of an enterprise, industry, sector of the economy or the economic system as a whole..

Authors: Mudra M.S.
Published: December 2023

The article presents a formalized economic-mathematical model that makes it possible to estimate the effect of the joint introduction of information modeling in construction and an integrated project management system to solve the tasks of extracting from the overall effect of the enterprises' activity the share that arises as a result of the introduction of innovations.

It was determined that the analysis of empirical data is a mandatory condition for the formation of proposals for improving the activities of economic entities, in general, and the development of direct measures within the limits of individual functional types of activity, in particular. In order to obtain up-to-date and verified information about the activities of the studied enterprises, the work pays attention to the analysis of trends in the development of domestic construction. An analysis of the destabilizing effect of factors on the economic security of these enterprises is presented using the approaches and indicators of the rating assessment of Doing Business business conditions. This approach allows detailing the general state of the business environment at the macro level and explaining the deep processes of the response of the enterprise management system to the challenges of modernity, which form a certain security environment at different levels of management of complex socio-economic systems.

A model of flexible management of the enterprise has been developed to ensure its economic security, which is built on the basis of two-component neural network diagnostics, taking into account the needs of the main stakeholders and determining the internal and external factors influencing the enterprise's activities. The model allows management to determine the most relevant list of management decisions and take into account external and internal threats, which ensures an increase in the level of economic security of the enterprise due to sufficient flexibility of the management system and timely response to current threats.
Monitoring of the technical condition of buildings and structures under operational conditions
Authors: Umanets I. , Basarab V.
Published: December 2023

The article is devoted to monitoring the technical condition of buildings and structures in operational conditions. Monitoring the technical condition of buildings and structures helps to understand the real condition and get recommendations for eliminating defects. Assessment of the technical condition of buildings and structures is necessary to ensure their operational suitability. Usually, monitoring includes a number of different methods that allow to assess the technical condition of the object in dynamics based on periodic (monthly, weekly) observations. The relevance of research was emphasized, which was determined by the practical need to assess the technical condition of the load-bearing structures of buildings and structures under the influence of natural and climatic factors and human activity, which would allow predicting the occurrence and development of emergency situations with high reliability. The purpose of the work is established, which consists in the development of a theoretical-experimental methodology for assessing the technical condition of load-bearing structures of buildings and structures during monitoring using modern information technologies for data acquisition and processing. An analysis of modern natural (experimental) methods of assessing the technical condition of buildings and structures, as well as computer modeling methods, was carried out. The expediency of conducting the survey, which consists in establishing the real bearing capacity and operational suitability of the building (structure), is indicated. The purpose of the survey is to obtain data to determine the reliability of the building, the need for strengthening, repair, reconstruction, modernization and development of the necessary project documentation. The principles of building a system for monitoring the technical condition of buildings (buildings), the basic structure, and engineering solutions were described. An analysis of the main theoretical methods of modeling the technical condition of the building was carried out. The method of building an information system for obtaining data from sensors of physical parameters, as well as recording, processing, comparing with theoretical models and making management decisions in case of deviation of operational parameters from permissible values was given. It is proposed to solve the inverse problem using predictive mathematical models, namely: designing a building (structure) with predetermined (according to the project) parameters of technical condition and operational reliability.
Improvement of organizational and technological tools for assessing the effectiveness of construction and investment projects

Published: December 2023

The main principles and approaches to construction planning and production organization are taking into account the dependencies between the terms of project implementation and its cost. The basis of this methodology for determining the effectiveness of the implementation of construction projects is the methods and methods by which the participants of the construction and investment process determine the duration and cost of construction during tenders at various stages of organizational and technological development.

The effectiveness of improving these methods essentially depends on how fully they take into account the specific features of the management-control, organizational-technological, and financial situations in which the construction will be carried out.

A very wide and diverse list of factors can affect the structure and indicators of construction projects. Among them, for example, the relative remoteness of the main suppliers of resources from construction sites, the underdevelopment of the construction industry in some regions of the country, the influence of climatic factors on the productivity of labor, other powerful influence of elements of the external environment and the impact on project results in existing models and methods. As a result, we have a real duration of construction higher than the proposed one.

This is especially relevant in conditions where improving the efficiency of capital investments in construction projects requires finding organizational and management tools to increase the level of economic relations in construction, strengthen contractual discipline, and increase the economic responsibility of builders and customers for the final results of construction projects.

Implementation of construction projects is associated with high costs. In order to effectively use existing methods of construction planning and production organization in the established economic conditions, to have a positive impact on the acceleration and efficiency of construction, it is necessary to add methods that take into account the existing specific features of the construction industry. The need to create a certain toolkit for solving tasks related to increasing the efficiency of construction projects, minimizing the duration of projects and maximizing profit, taking into account organizational, technological, economic factors and elements of the external environment, determines the relevance of this scientific research.
The use of pile columns during the building construction by the top-down method
Authors: Makhynia O. , Halenko Y.
Published: December 2023

The article examines the analysis of publications regarding the use of various types of piles-columns during top-down construction. Today, the following types of piles can be used during construction using the "up-down" technology: bored piles, bored piles with a barrel extension (bell pile), barrettes (barrette), combined piles with a steel core (king post). The article analyzes the buildings that were built by the "up-down" method, as well as the structural characteristics of the piles-columns that were used during their construction. It was established that pile-columns are expected to absorb loads in a wide range from 1.5 to 44.5 MN, on average the calculated load is from 10 to 14 MN. The length of the piles varies from 16 to 67 m, on average - 30...35 m, and they were placed with steps from 1.8 to 4.3 m, on average - 3 m. A growing trend of using combined piles with a metal core (king post) was revealed. Their main advantage is the ability to immediately perceive significant loads from the above-ground part of the building during the simultaneous construction of its underground part and guaranteed indicators of strength and stability of the column. Installation of combined piles with a metal core (king post) involves two stages. At the first stage, a pit is arranged and a reinforcing frame is installed to it, then a concrete mixture is laid to the lower monolithic part of the pile, into which the steel core of the upper part is mounted and it is covered with gravel in the pit. At the second stage, during the construction of the underground floors, the metal core is concreted. At the same time, it was established that the installation and concreting of a metal body is a technologically complex and expensive process that requires a more detailed study of the possibility of improving structural and technological solutions and reducing the cost of work.

The use of secondary industrial products has long been an integral part of the construction industry. The most common man-made raw materials used in the production of building materials, in addition to slag, are fly ash and red mud.

This work is devoted to the study of the effectiveness of using red mud as an additional source of an alumina silicate component of man-made origin in the production of alkali-activated cements with increased acid resistance.

In conventional cement systems, the use of significant amounts of red mud is not possible due to the high content of alkali metal compounds and heavy elements, but this is not a problem for alkali-activated binders.

Red mud obtained by processing bauxite ore using the Bayer process is highly alkaline, and its disposal and reusability are hampered by high sodium concentrations and high pH. That is why, according to the analysis of literature sources, research on the integrated use of red mud is mainly found in only a few areas, among which construction occupies a leading position.

In the course of research, the parameters of dough of normal density, hardening terms and strength for the developed systems were determined. Direct determination of the acid resistance index was also carried out using two methods: accelerated and by long-term aging of samples. In this way, the main physical and mechanical characteristics of the developed compounds were determined and the results were analyzed.

The obtained results of the study confirmed the possibility of partially replacing alumina silicate components with red mud to obtain acid-resistant alkaline cements. It was found that the introduction of up to 30% of red mud makes it possible to obtain material with an acid resistance coefficient (Ks) in the range of 0.8-0.95.

In an era marked by constant technological changes and the transition of many business processes of enterprises to digital reality, construction participants are forced to review their principles and methods of construction work in order to remain at the forefront of innovative activities. This article examines methodological and practical approaches, as well as the main principles used for the successful integration of ideology, technologies and principles of building information modeling (BIM) into the operational structure of construction participants and stakeholders (using the example of engineering enterprises).The methodology lays the foundation for the implementation of BIM, emphasizing the strategic and combination of systemic, situational, function-oriented and process-oriented approaches, provides guidance to companies on adapting the implementation of building information modeling to improve productivity, optimize work processes and optimize overall project results. As a result of the transformative impact of BIM on project stages, from initial planning and design to modeling, construction and ongoing maintenance, digitization acts as a catalyst for positive change in projects.The article examines how building information modeling technologies fit within existing systems and project management actors commonly used in engineering practice and improve them. Issues related to data sharing and collaboration between interdisciplinary team members (designers, contractors, developers, suppliers, engineering firms, etc.) are addressed, demonstrating how building information modeling can be integrated into a variety of engineering processes.By offering a synthesis of methodological approaches, practical ideas, and overarching principles, the paper provides academics and construction professionals with a framework for implementing VIM, contributing to a paradigm shift toward more advanced, sustainable, and effective engineering practices.
Forecasting by Analogy: A Parallel between the Trend of Confirmed COVID-19 Deaths in the Winters of 2022/2023 and 2023/2024 in Italy
Authors: Roccetti Marco
Published: December 2023

We studied the weekly number and the growth/decline rates of COVID-19 deaths in the period October 31, 2022 – February 9, 2023, in Italy, finding that that COVID-19 winter wave reached its peak during the three holyday weeks extending from December 16, 2022 to January 5, 2023, and it was definitely trending downward, returning to the same number of deaths of the end of October 2022, in the week February 3 – 9, 2023. During this period of fifteen weeks, that wave caused a number of deaths as large as 8,526. Its average growth rate was +7.89% deaths per week (ten weeks), while the average weekly decline rate was -12.32% (five weeks). Currently, Italy is experiencing a new COVID-19 wave, with the latest six weekly bulletins (October 26, 2023 – December 14, 2023) showing that the deaths have climbed from 148 to 322. The weekly growth rate has risen by +14.08% deaths, on average. In the hypothesis that this 2023-2024 wave have a duration similar to that of 2022-2023, with: i) a comparable extension of both the growing period and of the decline period and ii) similar growth/decline rates, a prediction can be cast regarding the number of COVID-19 deaths in the period November 2023 - January 2024. They could reach the amount of 4100-4200.

We adopt the spirit of the traditional Chinese medication (including Chinese cuisine) to the effect that the human body is to be viewed as a whole as it is. By invoking a few universally established principles in biochemistry-physiology-nutrition, i.e., using modern medical principles as a touchstone, we revive the ancient Chinese wisdom of the Wu xin principle (five elements) and Five-storied pagoda principle and we deduce a plausible conclusion that the effect of fire is to be weakened by water: Xiangke of fire (oxygen) and water (antioxidant). Then we go on to show that affinity of water and soil, metal and tree explains the nutrition of the human body by vegetable, metal ions, and fruits. Five-storied pagoda principle tell that water is squeezed by soil and fire, which explains the affinity and conflict of these elements. Wind is to be interpreted to mean oil and cosmos to mean the mind.
