PENAFSIRAN VICTIM PRECIPITATION UNTUK PEMIDANAAN KEKERASAN SEKSUAL
Authors: Kurniawan Riza Alifianto , Felisiano Iqbal , Astutik Astutik
Published: June 2023

Victim precipitation bagi korban tindak Pidana tidak dapat diartikan sebagai kontribusi korban yang menimbulkan pelaku melakukan kejahatan. Kontribusi korban dalam viktimisasi yang dialami akan membuat korban mendapat beban kesalahan yang dapat membuat korban menderita. Artikel ini memberikan pendapat yang berkaitan dengan argumentasi peranan korban yang memotivasi pelaku melakukan tindak pidana tidak dapat menjadi alasan pengurangan sanksi bagi pelaku. Pemberian pengurangan pidana dengan alasan adanya kontribusi korban dalam proses viktimisasi sangat mencederai harapan korban untuk pemidanaan yang berat bagi pelaku. Konsep victim precipitation harus dapat ditafsirkan bukan sebagai alasan pengurangan hukuman pelaku kekerasan seksual, konsep tersebut seharusnya menjadi kebijakan untuk pencegahan kekerasan seksual untuk mendapatkan cara pencegahan yang efektif.

The Morros Garapenses Environmental Protection Area (EPA) is home to significant biodiversity and an important paleobotanical site, with Permian fossil records, being a strategic area for studies in Maranhão. The objective of this study was to provide a list of species of phanerogams from the Morros Garapenses EPA. The material was collected through the walking method on pre-existing trails at different elevations and phytophysiognomies. The collection, herborization, identification, and classification of species followed the usual methodology for this type of research. A total of 297 species distributed in 196 genera and 70 families were cataloged. The families with highest specific richness were Fabaceae (60 species), Malvaceae (20 spp.), Rubiaceae (18 spp.), Cyperaceae (16 spp.), Euphorbiacae (14 spp.), and Bignoniaceae (13 spp.). Forty-nine species were endemic to Brazil, fifteen are being reported for the first time from Maranhão, and five from Cerrado. Several phytophysiognomies were found in the area, namely, Cerradão (33 species), Campo sujo (7 spp.), typical Cerrado (154 spp.), veredas (10 spp.), riparian forest (5 spp.), and anthropized areas (5 spp.). The study revealed a significant number of species in the Morros Garapenses EPA, stressing the urgent need to create a management plan for the sustainable use of natural resources and recovery of degraded areas.

Published: June 2023

Albuminuria standardization is a key issue to produce reliable and equivalent results between laboratories. We investigated whether official recommendations on albuminuria harmonization are followed in the literature. The PubMed database was searched from June 1 to September 26, 2021. The search terms included urine albumin, urine albumin-to-creatinine ratio (uACR), and albuminuria. A total of 159 articles were considered eligible; 50.9 % reported the type of urine collection. Specifically, 58.1 % collected a random spot urine specimen, 21 % collected a first morning void, and 6.2 % collected a 24-h specimen. Overall, 15 % of articles reported data on sample shipping, storage, and centrifugation and 13.3 % mentioned the preanalytical phase without any data on albuminuria. The method for albuminuria was properly described in 31.4 % of articles; of these, 54.9 % used immunological methods, and 8.9 % contained errors or missing data. Most articles (76.7 %) expressed test results as albuminuria-to-creatininuria ratio. Different decision levels were utilized in 130 articles; of these, 36 % used a decision level of ≤30 mg/g creatininuria and 23.7 % used three decision levels (≤30, 30–300, and ≥300 mg/g). The failure to follow guidelines on albuminuria harmonization was mainly found in the preanalytical phase. The poor awareness of the importance of preanalytical steps on test result may be a possible explanation.

Published: June 2023

Objectives

The trueness and precision of clinical laboratory results are ensured through total quality management systems (TQM), which primarily include internal quality control (IQC) practices. However, quality practices vary globally. To understand the current global state of IQC practice and IQC management in relation to TQM the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a survey of IFCC member countries on IQC practices and management.

Methods

The survey included 16 questions regarding IQC and laboratory TQM practices and was distributed to IFCC full and affiliate member countries (n=110). A total of 46 (41.8 %) responses were received from all regions except North America.

Results

Of the responding countries, 78.3 % (n=36) had legislative regulations or accreditation requirements governing medical laboratory quality standards. However, implementation was not mandatory in 46.7 % (n=21) of responding countries. IQC practices varied considerably with 57.1 % (n=28) of respondents indicating that they run 2 levels of IQC, 66.7 % (n=24) indicating they run IQC every 24 h and 66.7 % (n=28) using assay manufacturer IQC material sources. Only 29.3 % (n=12) of respondents indicated that every medical laboratory in their country has written IQC policies and procedures. By contrast, 97.6 % (n=40) of responding countries indicated they take corrective action and result remediation in the event of IQC failure.

Conclusions

The variability in TQM and IQC practices highlights the need for more formal programs and education to standardize and improve TQM in medical laboratories.
The Mirror Image of Sino-Western in America’s First Work on Travel to China
Authors: Yang Jing
Published: June 2023

American travel writing on China, The Journals of Major Samuel Shaw, the First American Consul at Canton With a Life of the Author, not only reflects the image of China in the mid-Qing dynasty from a Western perspective, but also presents the self-conception and identity construction of early Americans. Shaw’s understanding of China prior to his arrival in China was influenced by public opinion, his community, and his reading experiences, leading him to approach his observations of China through a complex filter of romantic imagination and grandiose expectations, and commercial incentives, as well as malicious misinterpretations. While in China, his idealized vision of the Chinese market was tempered by his critical stance toward the Qing government and legal culture, which were closely linked to American interests. Shaw’s journals deconstructed the image of China as a utopia and marked an important turning point in the history of American perception of China. This study explores the trajectory of this transition and reflects on the discursive construction of American national identity in the process, tracing Samuel Shaw’s evolving perceptions of China and his influence on American politicians, businessmen, and the general public.
Nrf2 protects against myocardial ischemia-reperfusion injury in diabetic rats by inhibiting Drp1-mediated mitochondrial fission
Authors: Wang Xiao-Li , Zhu Qian-Qian , Simayi Alimujiang , Xu Gui-Ping
Published: June 2023

Mitochondrial dysfunction and oxidative stress are considered to be two main drivers of diabetic myocardial ischemia-reperfusion injury (DM + MIRI). Nuclear factor-erythroid 2-related factor 2 (Nrf2) and Dynamin-related protein 1 (Drp1) play central roles in maintaining mitochondrial homeostasis and regulating oxidative stress, but the effects of the Nrf2-Drp1 pathway on DM-MIRI have not been reported. The aim of this study is to investigate the role of the Nrf2-Drp1 pathway in DM + MIRI rats. A rat model of DM + MIRI and H9c2 cardiomyocyte injury were constructed. The therapeutic effect of Nrf2 was assessed by detecting myocardial infarct size, mitochondrial structure, levels of myocardial injury markers and oxidative stress, apoptosis, and Drp1 expression. The results showed that DM + MIRI rats had increased myocardial infarct size and Drp1 expression in myocardial tissue, accompanied by increased mitochondrial fission and oxidative stress. Interestingly, Nrf2 agonist dimethyl fumarate (DMF) could significantly improve cardiac function, mitochondrial fission, and decrease oxidative stress levels and Drp1 expression after ischemia. However, these effects of DMF would be largely counteracted by the Nrf2 inhibitor ML385. Additionally, Nrf2 overexpression significantly suppressed Drp1 expression, apoptosis, and oxidative stress levels in H9c2 cells. Nrf2 attenuates myocardial ischemia-reperfusion injury in DM rats by reducing Drp1-mediated mitochondrial fission and oxidative stress.
Tradição, Família e Propriedade (TFP), anticomunismo e a comunidade de inteligência dos EUA
Authors: NEVES JUNIOR J. W. A. , LANZA Fabio
Published: June 2023

The following article investigates the positions of the United States intelligence community in terms of the potential alignment, or not, between the Brazilian fundamentalist Catholic group with anti-communist leanings, Tradition, Family, and Property (TFP) and the anti-communist crusade led by Washington during the period of the Cold War (1947-1991). Selected sources of investigation are documents declassified by the Central Intelligence Agency (CIA) available from the agency itself and the US Department of State, which were published by the Opening the Archives project at Brown University. The sources were approached according to the method of document analysis and from the theoretical prism of Mannheim’s interpretation of styles of thought. As a result, we identify that the American declassified documents recognize the TFP’s potential to indirectly meet the US’s needs in Brazilian territory, despite the fact that the organization was deemed by the American intelligence Community to be incompatible with Brazilian Catholicism’s world view and its sometimes irrational actions were also not aligned with the anti-communist standards proposed by Washington.
Gilberto Freyre, identidade nacional e Latinoamericanidade
Authors: COELHO Claudio M. , RODRIGUES M. B. F.
Published: June 2023

The main aim of this essay is to present a set of reflections on Gilberto Freyre, highlighting his ideas on national identity and Latin Americanness. What connections may we establish between his work Casa-Grande & Senzala [The Masters and the Slaves] (1933) and various issues which remain relevant to the current Latin American political debate? First, we locate Freyre’s thoughts within the Latin American debate on issues around national identity. We then move on to proposing several theoretical reflections and methodologies that we consider key to the debate on the theme of our work, namely: Gilberto Freyre’s political thought and his strategies for Brazil; the author’s studies abroad (in the US and in Europe) and the epistemological repercussions in Casa-Grande & Senzala; Freyre’s own brand of romantic conservatism and Brazilian politics; and the relations between ethos and pathos in the implicit political pact in Freyre’s work. Finally, we provide a summary of Freyre’s debate on Americanness (at the onset of the 1940s) and his political agenda for Latin America.
The Repercussions of the Untold, and Why One Needs to Know
Authors: Pabst Kathrin
Published: June 2023

The article takes its starting point in more than 160 personal narratives from former migrants, their children, and grandchildren. The testimonies have been collected by cultural-history museums in seven European countries – Norway, Denmark, Sweden, Poland, Lithuania, Slovenia and Croatia – and provide a haunting impression of the long-term consequences of war and forced migration for at least three generations. The research aimed at understanding how exactly the Untold and the silence of the first generation – the not-sharing of what they, as time witnesses, experienced – can be sensed by their children and grandchildren and influence their lives, family relations and the surrounding society in a negative way. The findings show that the need for personal and public information by the second and third generations cannot be overestimated and that sharing and getting to know could be a key to more healthy relations between family members and within communities.
Voices Heard (Again)
Authors: Nikočević Lidija
Published: June 2023

The emigration of Istrian Italians after the Second World War, most often called the “Exodus”, has been a frequent topic of many historical and anthropological studies. This paper reports on new findings based on the EU project Identity on the Line, which studied and interpreted a series of involuntary migrations and unwanted consequences for peoples, communities and individuals in Europe in the middle of the 20th century. In the research of the Istrian “Exodus”, an effort was made to find new testimonies and stories and reach voices that had not been “heard” thus far. In this process, it became obvious that the status and fate of the Istrian Italians who did not emigrate, the so-called “Rimasti” (less studied so far) is very complex due to the ambivalent relationship with the emigrated Istrian Italians (the “Esuli”) as well as with the newly created social environment. Photographs and statements from both communities were collected and meant to be used for two exhibitions, films and publications, thus bringing to light their intimate accounts (some of which were told for the first time), presenting them in a public space. This transformation necessarily implied very careful and sensitive cooperation with the informants, with the aim of making their traumas more visible, as well as establishing museums as institutions where increased efforts are made to communicate “difficult heritage”.

Published: June 2023

Industrialization and export-based growth are very important in the development of emerging economies. In parallel, metropolitan cities have a positive effect on exports with high population density and advanced industrialization. Accordingly, in this study, the export performances of metropolitan cities in Turkey in 2022 was examined using integrated Multi-Criteria Decision Making (MCDM) methods and 30 metropolitan cities were ranked based on their export performances. Initially, five criteria which was affecting export performance were determined by using the relevant literature. These criteria are as follows: the export numbers of metropolitans in 2022, the number of countries exported, the number of exported sectors, the number of exporting companies and the areas covered by warehouses in metropolitan (m2). Then, the evaluation of the export performances of metropolitans were conducted by using CRITIC-based MULTIMOORA-WASPAS methods. The criteria weights were calculated by CRITIC method. Following this, the export performance of metropolitans was ranked by MULTIMOORA and WASPAS methods. The findings indicated that İstanbul, Kocaeli, İzmir and Hatay have the highest export performance during the period of 2022. On the other hand, Diyarbakır, Şanlıurfa, Ordu, Van and Erzurum have the lowest export performance in 2022.

İslamcılık, Osmanlı modernleşmesiyle birlikte gündeme gelen bir kurtuluş, ihya ve inşa projesi olarak düşünülebilir. Asırlarca üstünlüğünü kabul ettirip hükmettiği bir coğrafyanın karşısında “geri kalma” hissiyatı, Müslüman aydın ve düşünürlerini savunmacı bir hissiyata sevk etmiştir. Bu hissiyat dinin altyapısal bir unsur olarak var olduğu bir toplumda kurtuluşun reçetesinin de dinin içinde aranması gerektiği düşüncesini pekiştirmiştir. Batı karşısında yenilgiyi ve “geri kalmış” olmayı kabullenmeyen aydın ve düşünürlerce dinin içinden bir cevap verme arayışı ortaya çıkmıştır. Modernleşme ile dinin birlikte yürümeye başladığı süreçte Meşrutiyet İslamcıları da savunmacı bir perspektifle coğrafyalarına ve tarihsel dinamiklerine Batılıların “gördüğü” şekilde bakmaya başlamışlardır. Böylece kendilerini inşa ettikleri söylem, Batı dünyasıyla karşıtlık üzerinden temellenmiştir. Batı, Meşrutiyet İslamcılığının “öteki”si olarak hayatlarına girmiştir. Ancak bahsi geçen kavrayış içerisinde “öteki” bir taraftan kavga edilmesi ve yok edilmesi gereken bir unsur olarak tebarüz ederken diğer taraftan onunla bir “aşk” ilişkisi içine girilmiştir. Hem “öteki”ne benzeme çabası, hem de “ötekileştirdiği” üzerinden kendisini keşfetme hali oryantalizmin temel çerçevesini yansıtmaktadır. Meşrutiyet İslamcıları kendilerini oryantalistlerin prizmasında yeniden keşfetmişlerdir. Batı’nın norm ve değerleriyle düşünüp “hakikat”ini onun ilke ve prensipleri üzerine tesis etmişlerdir. Bu bağlamda, taleplerini ve tezlerini de oryantalizmin gölgesi altında ifade etmişlerdir.

Background. The aim of the presented research is a case study consisting in an analysis of publicly available Internet articles describing the phenomenon of influencers’ impact in the context of consumer behavior on the food market in Poland. This applies in particular to non-basic, impulsive, high-fat and high-sugar content foodstuffs. An example of that is previously unprecedented demandfor Koral Ekipa sorbet ice cream among children and school youth (up to 17 years of age), which is discussed in this paper. It was a phenomenon observed in April 2021 as a result of the PLL Koral marketing campaign carried out in cooperation with the most popular Polish youtubers, known as Ekipa Friza (Friz’s Team). Results and conclusions. The presented case study demonstrates the power of social media and influencer marketing in shaping consumer behavior among children and school youth. One of the commercial activities of the Team was cooperation with well-known producers and distributors of food products in Poland, such as PPL Koral, Dooti Donuts, Krynica Vitamin and Millano Group. The team assigned its name to four food products, with the Koral-Ekipa ice cream, introduced at the end of March 2021, having the greatest market success. Their sales exceeded by at least 300% other new products in over forty years of Koral's history. High sales figures for ice cream were already achieved in March and April, which prompted the manufacturer to launch an additional line, allowing the production of about one million ice creams a day. In this context, the authors also referred to the impact of influencer marketing on the health of young people and, consequently, the whole society
On the Functional Role of Gamma Synchronization in the Retinogeniculate System of the Cat

Published: June 2023

Fast gamma oscillations, generated within the retina, and transmitted to the cortex via the lateral geniculate nucleus (LGN), are thought to carry information about stimulus size and continuity. This hypothesis relies mainly on studies conducted under anesthesia and the extent to which it holds under more naturalistic conditions remains unclear. Using multielectrode recordings of spiking activity in the retina and the LGN of both male and female cats, we show that visually driven gamma oscillations are absent for awake states and are highly dependent on halothane (or isoflurane). Under ketamine, responses were nonoscillatory, as in the awake condition. Response entrainment to the monitor refresh was commonly observed up to 120 Hz and was superseded by the gamma oscillatory responses induced by halothane. Given that retinal gamma oscillations are contingent on halothane anesthesia and absent in the awake cat, such oscillations should be considered artifactual, thus playing no functional role in vision.

SIGNIFICANCE STATEMENTGamma rhythms have been proposed to be a robust encoding mechanism critical for visual processing. In the retinogeniculate system of the cat, many studies have shown gamma oscillations associated with responses to static stimuli. Here, we extend these observations to dynamic stimuli. An unexpected finding was that retinal gamma responses strongly depend on halothane concentration levels and are absent in the awake cat. These results weaken the notion that gamma in the retina is relevant for vision. Notably, retinal gamma shares many of the properties of cortical gamma. In this respect, oscillations induced by halothane in the retina may serve as a valuable preparation, although artificial, for studying oscillatory dynamics.

Published: June 2023

Nonfood lignocellulosic biomass is an ideal substrate for biohydrogen production. By avoiding pretreatment steps (acid, alkali, or enzymatic), there is potential to make the process economical. Utilization of regional untreated lignocellulosic biomass by cellulolytic and fermentative thermophiles in a consolidated mode using a single reactor is one of the ways to achieve economical and sustainable biohydrogen production. Employing these potential microorganisms along with decentralized biohydrogen energy production will lead us towards regional and national independence having a positive influence on the bioenergy sector.
Lyocell and cotton fibers as reinforcements for a thermoset polymer
Authors: Silva Cristina G. , Benaducci Daiane , Frollini Elisabete
Published: June 2023

Cellulose fibers obtained from the textile industry (lyocell) were investigated as a potential reinforcement for thermoset phenolic matrices, to improve their mechanical properties. Textile cotton fibers were also considered. The fibers were characterized in terms of their chemical composition and analyzed using TGA, SEM, and X-ray. The thermoset (non-reinforced) and composites (phenolic matrices reinforced with randomly dispersed fibers) were characterized using TG, DSC, SEM, DMTA, the Izod impact strength test, and water absorption capacity analysis. The composites that were reinforced with lyocell fibers exhibited impact strengths of nearly 240 Jm-1, whereas those reinforced with cotton fibers exhibited impact strengths of up to 773 Jm-1. In addition to the aspect ratio, the higher crystallinity of cotton fibers compared to lyocell likely plays a role in the impact strength of the composite reinforced by the fibers. The SEM images showed that the porosity of the textile fibers allowed good bulk diffusion of the phenolic resin, which, in turn, led to both good adhesion of fiber to matrix and fewer microvoids at the interface.

Published: June 2023

Cyprus is an island nation in the eastern Mediterranean Sea, with a rich and varied history of architecture. Located within a seismically active zone, Cyprus has experienced a number of earthquakes over the centuries, with some of them being particularly destructive. This initiative examines the evolution of architecture in Cyprus from 1489 to present, and how this evolution is related to seismic risk. Specifically, the work will register structural elements by time period, and analyze how these elements contribute to seismic response. Further it will explore the development of architecture in Cyprus, from the Venetians to the Ottoman Empire to the British Colonial period, the Greek-Cypriot period, and the modern era, and the structural elements of each time period. The paper describes how the structural elements of each time period affect seismic risk, and what modifications may be necessary in order to improve seismic risk in Cyprus. This paper will provide useful insight into the evolution of architecture in Cyprus and its effects on seismic risk.

Justification of the optimal option and transportation parameters for export supplies using marine transport
Authors: Onyshchenko Svitlana , Vyshnevska Olha , Vyshnevskyi Dmytro
Published: June 2023

The object of this research is transport provision of supplies using sea transport. The problem of increasing the efficiency of transportation of bulk cargo by bulk carriers or universal destination by optimizing the option and parameters of transport equipment is considered.
For categories of goods that are exported using sea transport, it is possible to use not only different options for transport equipment – own or leased (for vessels – time charter), but also different options from the point of view of the parameters of the vehicles. In this paper, the parameters are understood as the characteristics of sea vessels, on which the main economic indicators depend – deadweight, which reflects the size of the vessel and its carrying capacity for bulk carriers; as well as the age of the courts, which determines the cost of their rent and the level of operational costs.
The result of the research is an optimization model that allows to determine for each market a variant of transport equipment and its parameters. Model not only distributes deliveries according to transport options, but also determines which vessels of what size and age (for time charter) should carry out transportation. These results are focused on the exporter's decision-making process about sales markets in combination with decisions on transport provision before concluding contracts. Varying the size and age of the vessels makes it possible to consider a wider range of options from the point of view of parameters.
The practical use of the model allows the exporter at the stage of preparation (before the conclusion of contracts) depending on the volume of supplies and the market situation, including the freight one, to make decisions about options for transport support, which is taken into account when formulating transport conditions of contracts. Integral consideration of commercial (volumes of deliveries, transport terms of contracts), economic (price levels, freight rates, costs) and technological (size of vessels and their age) factors within the framework of the model allows taking into account the multifaceted nature of the problem of transport provision.
Formation of a minimum viable IT project team using the genetic algorithm
Authors: Blyznyukova Iryna , Teslenko Pavlo
Published: June 2023

The object of research is the process of forming an IT project team, in which the development technology is based on the technology of creating a minimum viable product (MVP) and design thinking (DT) technology. Such IT projects usually have a high content of innovation and require a special management technique, as well as a special approach to the properties of the project team.
The application of design thinking technology will require project team members to master the property of empathy for the customer's problems. Empathy is a property of the human representational system and cannot be acquired through education or training. If it exists, then this property can be developed thanks to special training. Therefore, there is a problem regarding the formation of the IT project team. The manager who is responsible for forming the team needs to make a decision to choose between the availability of technical competencies of the applicants, the ability to work in a team, and the presence of empathy. In addition to the outlined requirements for applicants, such a team must be self-managed and self-organized. This also adds a whole series of requirements to applicants for the IT project team. Usually, applicants possessing all the necessary properties in full do not exist. Therefore, the manager (expert) will need to make decisions about compromises in meeting all the project's requirements. In addition, the need for labor resources will change during the project life cycle (PLC). It is for this purpose that it is proposed to use a genetic algorithm (GA), which will allow finding a local extremum that will be optimal under the current conditions of the project to solve a multi-criteria problem. This will reduce the subjective component in the process of making project decisions, which in turn will increase the probability of successful completion of IT projects in conditions of uncertainty and dynamic changes.
The proposed method of forming an IT project team can be applied in practice in the form of information technology, to which in the form of a template it will be necessary to enter information about project requirements and the competency map of applicants. As a result, the GA will propose a decision regarding the quantitative and competent composition of the project team.

Published: June 2023

The object of study of this research paper is the processes of changing the properties of three-dimensional surfaces of a user avatar in real time. In the course of this work, the research addressed the limitations of existing solutions for synthesizing three-dimensional user avatars, particularly in terms of realism and personalization on mobile devices. Furthermore, the study tackled the challenge of efficiently adjusting color attributes without compromising the underlying texture information, ultimately enhancing user experience across various applications such as gaming, virtual reality, and social media platforms. A method consisting of three key components is proposed: pre-designed 3D models, multi-layer texturing, and software and hardware implementation. The multilayer texturing approach includes different texture maps, such as diffuse and occlusion maps, which contributes to the smooth integration of texture attributes and the overall realism of 3D avatars. The real-time change of surface properties is achieved by mixing the diffusion map with other texture maps using the Metal hardware accelerator, allowing users to efficiently adjust the color attributes of their 3D avatars while preserving the underlying texture information. The paper presents a software algorithm that uses the SceneKit game engine and the Metal framework for rendering 3D avatars on iOS devices. The result of the developed method and tool is a mobile application for the iOS platform that allows users to modify a digital 3D avatar by changing the model's colors. The paper presents the results of testing the proposed methods, means and developed application and compares them with existing solutions in the industry. The developed method can be implemented in areas such as gaming, virtual reality, video conferencing, and social media platforms, offering greater personalization and a more immersive user experience.

Object of article study is lignite humic acids hybrid modification technology of biodegradable films based on polyvinyl alcohol. The possibility of increasing the strength and operational properties of biodegradable polymeric materials based on polyvinyl alcohol by using its modification with the different types of humic acids from lignite is considered. Lignite humic acids hybrid modification films with antibacterial properties were obtained. The two-stage technology of lignite humic acids hybrid modification of biodegradable films based on polyvinyl alcohol was formalized. At the first stage of lignite humic acids hybrid modification technologies for hybrid-modified biodegradable materials production, lignite humic acids are received. At the second stage, hybrid modification of lignite humic acids (that are part of biodegradable polyvinyl alcohol films), which are received by watering from a solution, takes place. It has been conducted a study on determining the effect of lignite humic acids hybrid modification on the most important operational properties of biodegradable film based on polyvinyl alcohol, i. e., tensile strength, relative elongation at break and time of mold appearance. Changes in tensile strength, relative elongation at break and time of mold appearance for the lignite humic acids hybrid modified biodegradable polymeric materials based on polyvinyl alcohol were revealed depending on the content of the different types of lignite humic acids. It was also shown that the lignite humic acids hybrid modification of polyvinyl alcohol with the different types of humic acids allows preserving the biodegradability of the films along with imparting the antibacterial properties. The developed lignite humic acids hybrid modified biodegradable polyvinyl alcohol films with antibacterial properties, in terms of their operational characteristics, are superior to the known similar biodegradable films based on natural biopolymers.
Influence of electrochemically activated water on the physical properties and rheological indicators of meat pates

The object of research is the physical properties and rheological indicators of meat pates with corn starch suspensions prepared with activated water. Among the components of the composition of drinking water and food products, there are many substances with particularly inherent biological activity. The biological activity of water is caused by increased electronic or proton activity. Today, various ways of changing properties of water are known, but the most promising reagent-free method is the electrochemical activation of water. As a result of electrochemical treatment of water with an electric current, its electrochemical characteristics change. As a result, electrochemically activated aqueous solutions (catholyte/anolyte) are obtained; the water is saturated with oxygen, accelerates the removal of metabolic waste and promotes the most complete assimilation of nutrients.
The research was aimed at determining the influence of activated water in the composition of starch suspensions on the physical properties and rheological indicators of meat pates with their content. Activated water affects the pH value of pates, which in the meat industry indicates the freshness and quality of meat raw materials and products made from them. Before pasteurization, the pH value for all samples was practically identical. That is, at the initial stage, activated water does not affect the acidity of pates. In the process of storage, the concentration of (H+) ions increases in pates, and the pH shifts to the acidic side. Water activity indicators of pates with starch suspensions on activated water gravitate towards the indicators of pates more than to the indicators of starch, the range for which is within 0.280–0.400. The dependence of the change in shear stress on the relaxation time of pates showed that regardless of the dosage of the starch suspension, the values of the shear stress of the samples on the catholyte in the time range 0–300 s are significantly higher than the values of the samples on the anolyte and tap water. This is explained by the ability of these samples, having acquired the necessary structure, to be less exposed to the external influence of deformation and to keep the structure more intact. The creep curves of all samples testify about the trimodal nature of the classical experimental creep curve. Thus, the electrochemical activation of water modifies the properties of corn starch and significantly affects the rheological indicators of meat pates containing it.
The obtained results can be used in the development of recipes for meat pates and their production at enterprises.
Research of orthotropic composites failure taking into account their structural stochasticity
Authors: Kvit Roman
Published: June 2023

The object of the study is the construction of the reliability assessing algorithm for the orthotropic composite plate, taking into account the stochasticity of its structure under the conditions of plane deformation. The plate consists of a matrix and reinforcement elements. The main orthotropic directions of the material coincide with the directions of the loading. The conducted studies are based on the failure criteria expressed through the components of macro stresses. The hypothesis of the weakest link is used, which for the case of the statistical theory of strength sounds like this: the ultimate (failure) loading for an orthotropic composite plate is equal to the ultimate loading for its weakest element. Defects-cracks are characterized by independent random variables – the half-length and the orientation angle between the defect line and the axis of orthotropy with a higher modulus of elasticity. The proposed model of orthotropic composite material corresponds to known experimental studies epoxy phenolic fiberglass on the cord glass fiber. The distribution probabilities density of defect orientation takes into account their predominant orientation in the direction of reinforcement. On the basis of the obtained composite failure loading integral probability distribution function, the construction and study of the dependence of the plate failure probability diagrams for different number of cracks, structural inhomogeneity and type of applied loading was carried out.
Complex application of the composite materials fracture mechanics deterministic solution and the methods of probability theory and mathematical statistics allows for a more adequate assessment of the composite materials reliability, taking into account the stochasticity of their structure.
The main content of this work is the construction and analysis of dependence of stochastically defective reinforced composite materials failure probability diagrams.
The obtained results make it possible to evaluate the reliability of orthotropic stochastically defective materials under conditions of plane deformation.
The algorithm of a compatible combination of defectiveness and randomness of the orthotropic composite material structure makes it possible to qualitatively investigate its failure under various types of applied loading.
