Published: September 2023

The presence of heavy metals in the environment is mainly associated with anthropogenic human activity. These are ferrous and non-ferrous metallurgy, heavy industry, energy. Due to air pollution, heavy metals enter the soil and water.The first place among the polluters of the environment with heavy metals is electroplating industry, where two categories of effluents are formed: spent concentrated effluent sanddiluted washing waters. In reservoirs, heavy metals have the ability to accumulate in the bottom sediments and thus are a source of second air pollution. They are not capable of biodegradation, but are able to accumulate in system components, causing a toxic effect on the animal world, humans and microorganisms. Different heavy metals affect the environment and biota in different ways. They can cause malfunction of the kidneys, liver, pancreas, accumulate in various organs and bones, causing their dysfunction. The greatest danger is heavy metals – chromium, nickel, cadmium, zinc. Their persistence, toxicity, ability to bio accumulate and migrate through trophic chains pose a danger to the existence of hydrobionts, animals and, above all, human health. The authors offer technologies for cleaning wastewater from heavy metals: reagent technologies, bacterial purification technologies, as well as phytotechnologies. Proposed sewage treatment plants for the removal of heavy metals from wastewater. The pollution of surface water sources, human health and living organisms will depend on the reliable extraction of heavy metals from spent galvanic effluents.

The purpose of the article is to develop a process of managing the professional (dynamic) risks in freight transportation due to changes in time of dangerous factors.To build the process of managing the professional (dynamic) risks of truck transportation, the main principles of system dynamics using the "tie-butterfly" model for establishment the causal and reciprocal relationships between dangerous factors affecting the drive were used.A model of the connection of dangerous factors of the internal and external environment of the organization, related to their negative impact on the increase in the probability of the occurrence of a dangerous event (incident) and the degree of severity over time, has been developed. Based on the interaction of the probability of the occurrence of a dangerous event and the severity of the consequences, taking into account changes in the physical and psychological state of the driver, it became possible to develop a dynamic model for assessing the driver's professional risk. Changes in professional (dynamic) risks during the time of a truck driver are proposed for analysis: by hours of the day (from 00:00-24:00 hours); by days of the week (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday); by season (spring, summer, autumn, winter). Taking into account the interaction of three main components: the presence of a threat or danger, the interaction between a truck and a person, the presence of a catalyst (physical and psychological state of the driver), the amount of professional risk is determined. To check the adequacy of the assessments, taking into account the change in the influence of dangerous factors on the probability of the occurrence of a dangerous event and the degree of severity of injuries from it with a time, an algorithm that allows to monitor every step in the management of professional risks was developed. It was established that an unacceptable level of risk is fixed at night and in winter, under inappropriate climatic conditions, which requires the development of effective safety precautions.The scientific novelty consists in the justification of a dynamic model from assessing the professional risk of a driver, based on the interaction of the probability of the occurrence of a dangerous event and the severity of the consequences, taking into account changes in the physical and psychological state of the driver.The practical significance lies in the development of forms for assessing the driver's professional risk.
CLASSIFICATION OF CONTEMPORARY HOUSING IN THE HISTORICAL CONTEXT
Authors: Popovych Dmytro
Published: September 2023

Preservation of historical buildings while accommodating modern housing is a difficult challenge in urban development. The successful integration of contemporary architectural design within the context of historic districts requires careful consideration of various factors. In this article, we present a comprehensive classification scheme for modern housing in historic buildings based on a careful analysis of practical experience and architectural principles. The classification scheme covers eight key features that serve as the main parameters for evaluating and classifying modern housing in a historical context. These features include project quality classes, floor plan, functionality, volume-spatial structure, construction method, furnishing materials, color scheme and approach to harmonization with the historical context. Classification signs are divided into different categories, sometimes into subcategories and cover the relatively maximum load of world experience in the design of modern housing in a historical context. The project quality classes are divided into mass housing and housing of increased comfort. Flooring is defined by three categories: low-rise, medium-rise and multi-story. Different forms of spatial and volumetric structure, which flow from different sections of the design and structure of quarters in the historical districts of the cities, are defined. Furnishing materials are divided into traditional, modern, and combined options. On the basis of historical architecture, coloristic categories are defined, which either repeat the historical colors of the city, or contrast against their background. Also, residential buildings are defined according to functionality, while multi-functional residential buildings are divided into several categories according to various variants of architectural and planning solutions of complexes. The last feature is the main feature in the case of determining the harmonization of modern housing with the historical context and is divided into 5 categories, starting from pseudo-historical design and ending with the contrasting formation of modern architecture.

Published: September 2023

Introduction. At this time the  language  continuum  of Dutch on the  territory of Flanders undergoes  significant changes  and develops in the direction of three-part  paradigm, which consists  of the  standard  Dutch language,  intermediate (tussentaal)  and  various  dialects which explains the actuality of the studies of the intermediate language. The purpose of the study is to analyze the variety of the intermediate language, its components, combinations and correlation  between  the dialect features  and the features  of the standard language, as well as to analyze the problem of distinguishing the dialects and the intermediate language which explains the novelty of the study.

Methodology and  sources. The study of conducted  using the  publications  and articles  in Dutch (Flanders), TV series,  talk-show on the Flemish TV, interviewing some  informants.  The data was collected  and analyzed using the method  linguistic observations, questioning  and comparative analysis. The theoretical  basis of the research is language variation.

Results  and  discussion.  In  the  intermediate  language  of  the  language  continuum  of Flanders  there  are  different  variants  which are  formed  due  to  the  interference of  the primary, secondary  and tertiary dialect features, as well as due to the interference of the elements of the standard  language in different degrees.  There are general  features  of the intermediate language typical for all territory of Flanders on the one side and on the other side  local  differences. The  intermediate  language  gains  strong  positions  in the  media, culture and advertising.

Conclusion.  Some dialect features  have a high degree  of interference in all variants of the intermediate  language  in  Flanders,  they  become  an  integral  part  of  the  intermediate language  and  don’t  prevent  the  speakers   from  understanding   each  other.  Due  to  the dominant  regional character of the variants of the intermediate language native speakers can easily identify the origin of the respondent.

Authors: İlhan Yulet , Avcil Cumhur
Published: September 2023

The present study endeavors to evaluate the therapeutic efficacy of a singular session of virtual reality (VR) exposure therapy for treating specific phobias. A total of 33 individuals with clinically diagnosed specific phobias were allocated into either a treatment group (N=16) or a waiting list control group (N=17). Measurement instruments included the Demographic Information Form, the DSM-5 Severity Measure for Specific Phobia Scale, and the Self-Reported Anxiety Measure. In terms of statistical analyses, a mixed-design analysis of variance (ANOVA) was utilized to examine both within-group and between-group differences over time, effectively allowing for a more comprehensive understanding of the treatment's impact. Results demonstrated a statistically significant reduction in the severity of phobia symptoms in the treatment group compared to the control group (p < .05). The therapeutic gains were maintained during a three-month follow-up assessment, with associated levels of anxiety and panic also showing a significant reduction in the treatment group (p < .01). This study corroborates the clinical efficacy of a single VR exposure session for the amelioration of specific phobias. The gains were not only immediate but also durable over a follow-up period, substantiating the longer-term effectiveness of this treatment modality. Despite certain limitations, such as the absence of active control treatments and a somewhat homogeneous sample demographic, the findings make a significant contribution to the extant literature. The study serves as an important foundation for future research that aims to broaden the applicability and understanding of VR-based therapeutic interventions for specific phobias.

Why are aging and stress associated with dementia, cancer, and other diverse medical conditions? Role of pineal melatonin interactions with the HPA axis in mitochondrial regulation via BAG-1
Authors: Anderson George
Published: September 2023

Pineal melatonin and the cortisol awakening response (CAR) are integral aspects of the circadian rhythm. Pineal melatonin release during sleep is proposed to optimize mitochondrial function and dampen any residual oxidant and inflammatory activity. Little is known about CAR, which is generally thought to prepare the body for the coming day, primarily through the activation of the glucocorticoid receptor (GR). Melatonin, like the gut microbiome-derived butyrate, suppresses GR nuclear translocation, indicating that pineal melatonin and night-time butyrate may interact to modulate CAR effects via the GR, including CAR priming of immune and glia cells that underpin the pathogenesis of most medical conditions. Cutting edge research shows that the GR can be chaperoned by bcl2-associated athanogene (BAG)-1 to mitochondria, where GR can have significant and diverse impacts on mitochondrial function. A number of lines of evidence indicate that melatonin indirectly increases BAG-1, including via epigenetic mechanisms, such as derepressing miR-138 inhibition of BAG-1. The dramatic decrease in pineal melatonin production over aging will therefore have significant impacts on GR nuclear translocation, but also possibly the levels of BAG-1 mediated mitochondrial translocation of the GR. This may have dramatic consequences for how CAR ‘prepares the body for the coming day’, via the differential consequence of GR location in the cytoplasm, nucleus or mitochondria, with differential effects in different cell types. The interactions of melatonin/butyrate/BAG-1/GR are especially important in the hypothalamus, where a maintained heightened melatonin concentration occurs over the night due to the direct release of pineal melatonin, via the pineal recess, into the third ventricle. The interaction of melatonin/butyrate/BAG-1/GR will have differential effects in different cell types, thereby altering the intercellular homeostatic interactions in a given microenvironment that will contribute to the pathogenesis of many aging-associated conditions, including neurodegenerative conditions and cancer. This reframes the nature of the circadian rhythm as well as how stress-associated hypothalamus-pituitary-adrenal (HPA) axis may modulate both the pathogenesis and course of diverse medical presentations. This has a number of research and treatment implications across a host of current medical conditions.
An insight into the importance of B vitamins and melatonin in the prevention of diabetes through modulation of the brain energy metabolism- a comprehensive review
Authors: Mukhopadhyay Manisha , Ghosh Priyanka , Chattopadhyay Aindrila , Bandyopadhyay Debasish
Published: September 2023

Energy metabolism is the biochemical pathway of converting macronutrients (carbohydrates, protein, and fat) to cellular energy for the maintenance of cell homeostasis. The brain is an organ that consumes unproportional energy compared to its size. Glucose (glycogen, in storage form of glucose) is the principal source of brain energy. Impairment in brain energy metabolism results in neuronal loss and subsequent neurodegenerative diseases including AD, PD, amyotrophic lateral sclerosis, Huntington’s disease, etc. However, metabolic disorders such as chronic hyperglycemia, and insulin resistance are also linked with neuronal activity. Dysregulation in neuronal transmission is associated with oxidative stress and brain insulin resistance. Diabetes mellitus jeopardizes brain function through various mechanisms including glucose toxicity, BBB damage, neuroinflammation, and gliosis. B vitamins as antioxidants and neuroprotective agents, can improve brain glucose metabolism. Melatonin is a potent free radical scavenger and it can also modulate cellular cytokine levels and prevent insulin resistance. The neuroprotective and antihyperglycemic effects of melatonin improve the brain's antioxidant defense system, decrease brain NOS activity, and prevent glucose toxicity. Hence this review suggests a therapeutic use of a combination of melatonin and  B vitamins to improve brain functioning disrupted by diabetes.

ON THE SUITABILITY OF MODULAR MULTILEVEL CONVERTER (MMC) IN HIGH VOLTAGE DIRECT CURRENT (HVDC) TRANSMISSION SYSTEM
Authors: Kadandani Nasiru B. , Hassan Sahalu , Abubakar Isiyaku
Published: September 2023

Transmitting bulk electrical energy over long distance by overhead transmission lines or submarine cables using high voltage direct current (HVDC) transmission system offers more flexibilities such as controllability of power flow and robustness against disturbances. Both current source converter (CSC) and voltage source converter (VSC) configurations have been considered in HVDC system. The former is used in HVDC transmission system involving stiff grid networks of higher ratings while the latter is commonly used in connecting to a weak grid. As such, special applications of HVDC such as connection between two or more weak grids and connection of wind power plants require the VSC configuration. However, in the conventional VSC configuration, the converter arm would have to be designed with large number of semiconductor switches that can block the full DC-bus voltage. However, with the evolution of modular multilevel converter (MMC) as a member of VSC family, sub-module (SM) chopper cells are used. This paper investigates the suitability of MMC in HVDC transmission system. The paper shows that the MMC configuration can generate any desired voltage levels required to synthesize a smooth output waveform, thus eliminating the need of heavy filters, has modularity in both hardware and software and generates very low harmonics.

Bourdieu’s Fields and Capital in Community Archaeology: An Example from Jordan
Authors: Miettunen Päivi
Published: September 2023

This chapter discusses Bourdieu’s field theory, capital and Habitus as possible theoretical tools for planning and establishing an archaeological community project. Collaboration and cooperation with local communities and stakeholders is acknowledged as an essential part of archaeological projects – not only as a means of decolonising the research field but, overall, to provide an ethical way to create long-term empowerment and benefits for local communities, and to make the research transparent and accessible. Various methods and tools have been proposed and tested for building and assessing community projects, but the heterogeneity of cultures and communities makes standardisation a challenging task. Using the Petra region in Jordan as a case study, I examine how Bourdieu’s theories could be utilised in understanding community structures, as well as in collaborating and creating long-term benefits before, during and after an archaeological project.

Published: September 2023

The study examines the economic transformation of Ughoton from 1440-1897. First, it assesses the agricultural activities, trade and crafts before 1440 in Ughoton. It discusses the changes that took place in agricultural activities including farming, fishing and hunting. It also analyzed development of Ughoton as a Benin port during the period of Benin-European trade relations. The study relied on both the secondary and primary sources of data. The primary sources consisted of oral interview and documentary data. The documentary data were sourced from intelligence reports, divisional annual reports, colonial letters, dispatches, government reports and correspondences. These data were obtained from State Archives and Record Services, Benin City and National Archives, Ibadan. The secondary sources includes books, newspaper, articles and periodicals. The study found that the introduction of maize, cassava and tree crops such as oranges, coconuts, tangerine, mangoes after the fifteenth century by the Portuguese boosted economic activity in Ughoton in particular and Benin Kingdom in general. The study also found that the introduction of fishing nets and hooks from the sixteenth century boosted the fishing activities in Ughoton. The study shows that the strategic location of Ughoton on the Benin river enabled it to serve as a Benin port for 4 centuries, which brought much wealth and fame to the kingdom and its monarchy.

Ergenlik dönemi, hızlı bir zihinsel, fiziksel ve psikososyal değişimlerin yaşandığı bir dönem olduğundan; bu dönemde, ergenlerin uyku düzeni ve kalitesi, zihinsel sağlık ve psikososyal gelişimlerinde büyük bir rol oynamaktadır. Ergenlerin uyku düzenleri, gelişimleri için oldukça önemlidir ve sosyal medya kullanımının uyku kalitesi üzerindeki olumsuz etkileri, ergenlerde daha belirgin olabilir. Bu nedenle, ergenlerde sosyal medya kullanımı ve uyku kalitesi arasındaki ilişki daha detaylı bir şekilde araştırılmalıdır. Söz konusu bu çalışmada, sosyal medya bağımlılığı ile ergenlerin uyku kalitesi arasındaki ilişki incelenerek ve çalışmanın sonuçları mevcut literatürle karşılaştırılmıştır. Çalışmaya yaşları 13 ve 18 aralığında değişen toplam 503 ergen katılmıştır. Bu durum dikkate alınarak bu çalışmada nicel yöntemlerden ilişkisel tarama modeli kullanılmış olup verilerin analizinde regresyon ve korelasyon analizi kullanılmıştır. Sonuç olarak, bu çalışmada sosyal medya bağımlılığı ve uyku kalitesi arasındaki ilişki araştırılmıştır. Araştırma sonucunda ergenlerde bu iki değişken arasında güçlü bir ilişki olduğu ve sosyal medya bağımlılığının uyku problemlerini anlamlı bir şekilde yordadığı saptanmıştır. Bu sonuçlar, sosyal medya kullanımının uyku problemlerine neden olabileceği ve ergenlerde sosyal medya kullanımının kontrol altında tutulması gerektiği konusunda önemli bir uyarı niteliği taşımaktadır. Ergenlerin uyku kalitesini arttırmak için sosyal medya kullanımını sınırlamak, akıllı telefonların yatak odasında kullanımını önlemek, rutin bir uyku programı oluşturmak, fiziksel aktivite yapmak, sosyal medya kullanımını sınırlandırmak için uygulamalar kullanmak ve sosyal medya kullanımı hakkında bilinçlendirme programları geliştirmek gibi öneriler sıralanabilir.

ABSTRACT
 THE EDUCATION CAMPAIGN ON STUNTING PREVENTION FOR CHILDREN AGED 0-5 YEARS OLD THROUGH THE POSYANDU PROGRAM IN TUNGKAL I VILLAGE, PINO RAYA SUBDISTRICT, SOUTH BENGKULU. The community service and development (KKN) course taken by the students is part of the Three Pillars (Tridharma) of Higher Education. Here, one of the KKN activities that we carried out was the education campaign on stunting prevention in children aged 0-5 years old for the local community, particularly for the parents, through the posyandu program in Tungkal I Village, South Bengkulu. This topic was chosen as it was one of the general topics determined by the P3KKN office and also taking into account that some people are still unaware of the importance of the stunting prevention issue thinking that stunting is a matter of hereditary factor. This activity was carried out to improve awareness and community participation in stunting prevention and early detection programs in toddlers. It is expected to directly motivate the community to pay attention to growth and development in their children to be optimum. The methods used were the extension and media campaign collaborated with the village of posyandu’s program. Hopefully, this activity will improve parents’ knowledge of stunting prevention and contribute to better nurture their children's growth and development.

Validation of a Model for the Formalization of Personal Learning Pathways Through Expert Judgment
Authors: Buitrago Rubén , Salinas Jesús , Boude Oscar
Published: September 2023

Personalized learning pathways enable students to take an active role in their learning. Therefore, the development of models that facilitate their design is crucial. This study aims to validate a model for formalizing personalized learning pathways for higher education students using the expert judgment technique. Two questionnaires were designed to validate content and internal consistency, respectively. The content was validated by a group of experts (n=12), while the internal consistency was validated by a nominal group (n=8). The results of content validity were satisfactory, and the level of agreement between judges, as measured by Kendall’s W test, was statistically significant in the implementation (p=0.007) and reflection (p=0.035) phases. To increase internal consistency, the study recommends implementing a simplified implementation scheme, adjusting the start-up phase in the conditional components (teacher digital literacy and technological environment), and incorporating teacher-student co-design. The improved ACDGE model emerges as a standard for designing learning pathways for higher education, minimizing the need to search for solutions to known problems.
Technologies for retrofitting non-road mobile machinery to reduce diesel emissions: a review and recommendation
Authors: Huang Zhenhua , Fan Hongqin
Published: September 2023

Non-road mobile machinery (NRMM) in Hong Kong emits considerable emissions and has been a major contributor of environmental regression and harm to the health of citizens. The severe problem caused by considerable NRMM diesel emissions has drawn the attention of the Hong Kong Government. However, the existing measures for reducing NRMM emission mainly target new NRMM while old in-service ones are being left largely unregulated. After a long time of use, in-service NRMM becomes inefficient through deterioration, which results in higher levels of diesel emissions, which are extremely harmful to public health. Transforming in-use dirty NRMM which are exempted from regulations on being greener and more fuel-efficient is an extremely urgent direction for the Hong Kong Government to pursue. Retrofitting in-service high-emitting NRMM can remarkably reduce emissions by using emission reduction technologies, improve the air quality, and achieve notable health benefits for people living or working in or near construction sites. Technologies for reducing emissions from NRMM are crucial for making NRMM greener and cleaner. Thus, this study reviews the technologies widely used for retrofitting NRMM to reduce emissions, to provide some significant insights and recommendations in the case of Hong Kong for initiating retrofit programmes and promote the application of emission reduction technologies.
