Features of the development of the Ukrainian and European print media market in the current conditions

The article analyses the state of the Ukrainian and European print market in the current conditions, which are caused by socio-political, military, economic and technological global processes. The author identifies the peculiarities of functioning and development of the print media market in the context of the Russian-Ukrainian war, which became a catalyst for a number of economic changes that led to a number of processes in financial terms: closure of publications, reduction of circulation, total transition to digital format, and, accordingly, transition to subscription. It is important to note that the above-mentioned processes took place in three stages: digitalization, the global economic crisis of 2013-2014 and Covid-19, and the war only accelerated them. The print media market cannot compete with other types of media. Falling circulation, closure of newsrooms or their mergers are typical for both the Ukrainian and European media markets. Today, this market and the online media market closely overlap, as print media, in order to survive financially and retain their audience in a highly competitive information environment, are actively moving to online platforms, often choosing social media as a place of operation. The study focuses on the print market in Poland, France, the UK, Germany and the Czech Republic. The European readership of traditional media consists of two parts: the older generation reads the printed version of publications, while the younger generation prefers to subscribe to digital analogues. It is more difficult for Ukrainian publications to retain their audience due to economic and military factors and a relatively young media market compared to the European one. The article emphasizes that the print media market is undergoing further active digitalization, which has particularly intensified during the Covid-19 period. This has given rise to the following trends: 1) updating of subscriptions to the digital format of printed publications; 2) transition to online formats of the same name, adaptation of the content of periodicals to social networks.

Application of the Life Cycle Assessment (LCA) Method in Assessing the Environmental Impact of New Materials Derived from Waste Polymers in Terms of Sustainability

Sustainable socioeconomic development should provide humans with a suitable environment for safe living. It can be debated whether the term “environment” should be used due to the significant anthropogenic transformation of the environment. Therefore, an essential part of solving environmental problems is innovation. Climate, resource conservation, and environmental protection are recognized worldwide as common challenges. Thus, it is necessary to implement solutions that simultaneously protect the environment and the climate with sustainable and rational use of resources. Related to this issue is the principle of a loop/closed-loop economy. Among other things, it refers to using waste to prepare materials that can be used for other purposes. The use of tools such as LCA (life cycle analysis) contributes to supporting environmental protection. With the LCA method, it is possible to analyze environmental risks and compare new technological alternatives. LCA is a methodology that has been used around the world with great success, especially for studying individual stages of the entire product life cycle. The results of studies that have been conducted in various research centers confirm the possibility of also using the LCA technique for the environmental assessment of new technologies or existing modernized technological processes. The purpose of this study was to assess the feasibility of using the LCA method to determine the environmental impact that the potential production and use of new materials will have.

Advancements in Colloidosome Fabrication, Functionalization, and Applications: A Comprehensive Review

Abstract: Among the recent developments in the field of microcapsules, colloidosomes microcapsules made of colloidal particles have elicited much interest in promising perspectives in microencapsulation technologies. First reported by Dinsmore et al., these structures hold a lot of potential in different areas of application, which include gene delivery, targeting the brain, and tumor treatment. However, the challenges associated with their permeability and stability limit the use of these coatings. Nevertheless, these problems define colloidosomes as possessing some features of protocells that include metabolic activities and response to stimuli, which make them significant in synthetic biology and biomimetic systems. In drug delivery, colloidosomes have the potential of providing solubility, stability, and a controlled rate of drug release, which will have an impact on the therapeutic use of drugs. Fabrication of colloidosomes is done in many ways, and the common ones include the mulsion strategy, layer adsorption, and microfluidics strategy. Some of these fabrication techniques have been investigated in the recent past to determine how their application can lead to enhanced colloidosome characteristics. Some of these methods include spray drying, sol-gel processes, and electrostatic assembly. For example, the study by Payizila Zulipiker et al. showed that different levels of permeability are controllable through the use of spray drying technology. Another study by Jia Jia et al. presented the preparation of pH-responsive colloidosomes and the high efficiency of encapsulation. Consequently, improvements in the manufacturing process and new self-assembly technologies that include microfluidics systems have also improved the creation of colloidosomes. New advancements in the field of colloidosome synthesis, as well as their surface modification, will open up numerous application prospects in the fields of pharmaceutics, regenerative medicine, and bioinspired materials science. New trends range from 3D printing to stimuli-responsive materials and design, as well as hybrid systems that are application- specific. Despite the difficulties that remain to be faced, colloidosomes represent an extraordinary opportunity for the growth of biotechnology and materials science to open the path to new generations of drugs and bioinspired applications.

Introduction. The assessment of the macro- and microporous structure of textile fabrics is increasingly relevant for predicting their permeability, dyeability, and decorative potential. This evaluation plays a crucial role in determining the hygienic properties of clothing materials, optimizing dyeing and finishing processes, and assessing the filtration capabilities of technical fabrics in various dispersed media.Problem Statement. Challenges persist in accurately predicting the permeability of textile fabrics, as well as in determining the optimal parameters for dyeing and finishing processes.Purpose. The purpose of this research is developing a rapid, cost-effective, and accurate method to evaluate the macro- and microporous structure of textile materials is essential for assessing their permeability and suitability for dyeing and fi nishing processes.Materials and Methods. To study the porous structure of textile fabrics, we select the fabrics that varied in the thread structure — yarn produced by traditional and shortened methods — and in the fibrous composition. The first fabric is made from complex polyamide threads in a plain weave, the second from twill-woven polyester fiber yarn, and the third differs from the second in the structure of the weft thread. The macro- and microporous structures of these textile fabrics have been assessed by means of drying methods and sorption thermograms.Results. The micro- and macroporous structures of textile fabrics made from polyamide threads and polyester fibers have been compared. It has been found that the fabric made from polyamide threads exhibits a significantly higher sorption capacity than the fabric made from polyester fibers. This finding suggests that the fabrics made from polyamide threads possess a more developed microporous structure. This fact enhances their dyeing and decorating capabilities as compared with the fabrics made from polyester fibers. A comprehensive approach, utilizing both drying methods and sorption thermograms, has been employed to evaluate the macro- and microporous structures of the textile fabrics. Conclusions. The proposed comprehensive approach enables comparative studies of various textile materials, allowing for the refinement of technological processes for dyeing and decorating, as well as the identification of potential applications for these materials.

THE EFFECT OF CEMENT KILN DUST ON THE PROPERTIES OF CEMENT

Due to the nature of the technological process, the cement industry is a significant source of dust. Managing industrial waste is a global problem worldwide; cement kiln dust is an example of such waste. The dust from the cement kiln is a by-product of the cement production process obtained during the grinding and burning of the raw materials inside the cement kiln. Still, due to its high alkaline content, it cannot be returned to the kiln, but its disposal and landfill can cause many environmental problems. It is necessary to find alternative methods for its utilization. Due to its fineness and composition like that of cement, there is a growing interest in the use of this powder as a partial substitute for ordinary Portland cement. The purpose of this paper is to investigate the influence of dust obtained during the production of cement clinker on the properties of cement (specific surface area, standard consistency, setting time, and compressive strength) and its implications in the conditions of its application.

Regulators for ensuring the sustainability of reproductive processes in industrial fruit growing

The necessity of developing a system of regulators to ensure the sustainability of reproductive processes in industrial fruit growing is substantiated. An assessment of the efficiency of fruit production in the Russian Federation is given. The factors influencing the decrease in the stability of reproductive processes in industrial fruit growing are identified: an increase in the cost of purchased resources; high cost of finished products; a reduction in the share of subsidies in the created cost of planting; the insufficiency of agricultural producers’ own financial resources for carrying out planned plantings renovations, updating production infrastructure funds and carrying out current production activities. Functional imbalances in the organization of reproductive processes in industrial fruit growing have been identified: internal structural imbalances, high resource intensity of production and technological processes, non-compliance with optimal comparability of production and economic indicators. Generalizing criteria for the sustainability of reproductive processes are systematized: the ability of the system to withstand negative impacts of an economic and natural nature; increasing the possibilities of expanded reproduction of all used resources; ensuring qualitative changes in the production, socio-economic, environmental parameters of the system; increasing the conditions for subsequent improvements, preventing production declines. The article characterizes and evaluates the effectiveness of existing regulators to ensure the sustainability of reproductive processes in industrial fruit growing (macroeconomic, technical, technological and economic). A system of regulators has been developed to ensure the stability of reproductive processes in industrial fruit growing in functional areas of influence. An algorithm is proposed to substantiate the necessary dimensionality of regulators to ensure the stability of reproductive processes in industrial fruit growing.
