Dictionary of Environmental Health
Authors: Spellman Frank R.
Published: February 2025

Every branch of science, every profession, and every engineering process has its own language for communication. Environmental health is no different. To work even at the edge of the major environmental aspects of this challenging field, you must acquire a fundamental but wide-ranging vocabulary and understanding of the components that make it up. As Voltaire said: "If you wish to converse with me, define your terms." In this publication, we define, and in many instances, fully explain in plain English, the terms or "tools" (concepts and ideas) used by environmental health professionals, environmental science professionals, safety/industrial hygiene practitioners/engineers, and non-science professionals.

It is important to point out that environmental health is not a single topic, but rather a complex, colorful, and diversified range of interrelated subjects including all of the basic sciences, computer science, government, engineering, energy, renewable energy, hydraulic fracking, security, disease, industrial hygiene, injury identification prevention and control, and much more. The practicing environmental health professional, specialist, technician or student of environmental health should know these topics—without them it is difficult, if not impossible, to practice in any of the environmental fields.

The Dictionary of Environmental Health is a one-of-a-kind comprehensive reference that serves as both a dictionary and encyclopedia. This book is an indispensable resource for individuals throughout environmental, occupational, and public health industries. It defines thousands of words illustrating the enormous magnitude of the environmental health field. Terms are alphabetically arranged with concise and succinct definitions along with expanded explanations wherever needed. These terms and definitions are drawn from varied, specialized, and technical environmental fields that can be understood by professional, students, and general readers alike.
Post-Apartheid Gothic
Authors: Joseph-Vilain Mélanie
Published: February 2025

Post-Apartheid Gothic: White South African Writers and Space analyzes the representation of space in recent works by South African writers. By combining analytical tools borrowed from Gothic studies with geocritical and postcolonial approaches, Mélanie Joseph-Vilain assesses the literary mechanisms utilized by Damon Galgut, Henrietta Rose-Innes, Lauren Beukes, Justin Carwright, and Lynn Freed to negotiate the complexities of post-apartheid identities in their fiction. Joseph-Vilain argues that the literary representations of emblematic places, real or imagined (the home, the farm, the city or the “non-places” of dystopia), express and reveal anxieties linked to the sharing of space in post-apartheid South Africa. The text successively (re-)visits the places that have been shaping South African white writing since Olive Schreiner’s African Farm—in other words, its topoi, both in the etymological sense of “place” and in the literary sense of recurring themes or arguments. Joseph-Vilain argues that these Gothicized topoi have provided writers with tools to explore the deep anxieties generated by the redefinition of South African society as the Rainbow Nation. While focusing specifically on the South African avatars of the Gothic and their interaction with local forms and genres like the plaasroman, the text also discusses the impact of globalization on South African literary, cultural, social, and political identities.

Published: February 2025

Wire arc additive manufacturing (WAAM), which uses arc as a heat source during the direct energy deposition (DED) process, is a melting-based additive manufacturing process that melts metal wires using an arc and then deposits them layer by layer to create components. It has the advantages of fast production speed and low cost. The WAAM process is mainly performed using a cold metal transfer (CMT) welder capable of low heat input. In this study, the deposition efficiency was studied through a deposition experiment on ferritic stainless steel 436 material. The research method is as follows: first, the appropriate variables of the deposition process (Arc length, Pulse/dynamic, Z-offset, Cooling time) were evaluated and conditions were selected, second, the amount of post-processing loss and deposition performance were evaluated through the deposition efficiency, and third, the mechanical properties were verified through a tensile test evaluation using the deposited specimen, and the appropriate process conditions were selected to create pipes that can be used in industrial sites by multilayer deposition of ferritic stainless steel 436 material.

Published: February 2025

Ultrasonic welding enables the bonding of materials with dissimilar thermal properties, making it a promising technology for industries requiring lightweight and high-strength components. This study investigates the effects of welding time on the joint characteristics of ultrasonic dissimilar material welding between 6000-series aluminum alloy and PA6-GF40 composite. In this study, tensile-shear tests were conducted to evaluate the changes in welding energy and joint strength under various welding time conditions. The joint cross-sections were observed using an optical microscope to assess joint quality and detect pore formation. The experimental results demonstrated that welding energy increased nonlinearly with welding time, and optimal joint strength was achieved under specific conditions. Additionally, optical microscopy revealed physical bonding and void formation at the interface between aluminum and PA6-GF40 composite. These findings provide insights into the relationship between welding time and joint strength, offering fundamental data for optimizing ultrasonic welding process parameters.

Potential antitumor effect of organochalcogenyl-benzoates in glioma cells
Authors: Zamin Lauren Lúcia , Silva Elisa da , Godoi Benhur
Published: February 2025

In the domain of brain malignancies, glioma, in particular the World Health Organization (WHO) Grade IV Glioblastoma, persists as having one of the worst prognoses in modern medicine. Despite the protocol leading to the convention of surgery with chemo-radiotherapy as the mainstay of treatment, mean survival rarely exceeds 18 months. In this work, we tested the antiglioma potential of three organochalcogenyl-benzoates containing an organoselenium group in their structure, obtained by chemical synthesis: 3-(phenylselanyl)prop-2-yn-1-yl nicotinate, 3-(phenylselanyl)benzoate)prop-2-yn-1-yl, and 3-((4-fluorophenyl)selanyl)prop-2-yn-1-yl benzoate. The tests were performed on a C6 rat glioblastoma cell line, which was treated with the compounds for different times (24, 48, and 72 hours) and concentrations (10-100 µM). After the treatments, MTT assays and cell counts were performed. All compounds showed cytotoxic effects, decreasing cell viability and the number of cells. For compound 3-((4-fluorophenyl)selanyl)prop-2-in-1-yl benzoate—which showed the most pronounced cytotoxic effects— analyses of cumulative population doubling, clonogenic ability, induction potential of senescence, and lipid peroxidation were performed. The compound was only able to induce a significant increase in lipid peroxidation, with no effect over the other parameters studied. The results presented here are unprecedented and promising, introducing new compounds with antitumor potential for glioma therapy.

Authors: Krein Daniela Dal Castel , Emer Cassandro Davi , Dettmer Aline , Piccin Jeferson Stefanello
Published: February 2025

Anthocyanins are phenolic compounds with high antioxidant properties obtained from plant sources, such as leaves, flowers, and fruits. As it is a thermosensitive compound, it requires a lot of control over the extraction method so that there is no degradation or reduction of antioxidant activity. In this context, this work presents a systematic review about anthocyanin extraction as well as a discussion of parameters that strongly influence the yield and amount of extracted anthocyanins, such as types of solvents and acidifiers, extraction time, solid-liquid ratio, and temperature. It was observed that solvent extraction and ultrasonic assisted extraction are the most used techniques, as well as methanol and ethanol, the most used solvents. The extraction is independent of the raw material but is optimized when performed at low pH and milder temperatures. The preference for polar solvents also stands out, due to the better solubility in relation to the bioactive ones.

Authors: Neimaier Alisson Silva , Prass Taiane Schaedler
Published: February 2025

O preenchimento de valores faltantes em séries temporais é um problema que tem recebido pouca atenção. Os estudos encontrados na literatura geralmente se concentram em modelos lineares da família ARIMA e não discutem a validade das metodologias propostas para casos com um grande volume de dados faltantes, nos quais métodos paramétricos tornam-se desafiadores devido ao problema adicional de identificar a ordem do modelo. Para abordar essas questões, este estudo propõe uma metodologia de reconstrução de séries temporais utilizando árvores de decisão, um método de aprendizado de máquina que não assume um modelo paramétrico para os dados. Nessa abordagem, os valores conhecidos da série temporal atuam como a variável resposta, enquanto as defasagens correspondentes são usadas como preditores. A árvore selecionada pelo algoritmo de treinamento é então usada para prever os valores faltantes na resposta. Simulações de Monte Carlo são utilizadas para investigar a metodologia proposta, considerando processos da família ARMA e o passeio aleatório,  variando o tamanho da série temporal, parâmetros dos modelos, proporção de valores faltantes e os preditores. Para avaliar a qualidade das reconstruções, as previsões das árvores de decisão foram comparadas com as de alguns m´métodos tradicionais de imputação. Os resultados demonstram o potencial do método proposto e são consistentes com o arcabouço teórico deste estudo. Para  promover a metodologia proposta, foi desenvolvido um aplicativo em Shiny que está disponível publicamente.

Published: February 2025

Soil organic carbon plays a crucial role in soil fertility, water retention, and overall ecosystem health. Understanding the geomorphological characteristics of environments where soils with high organic carbon content occur is essential for sustainable land management and conservation efforts. In this context, the objective of this study was to characterize the geomorphology of environments where soils with high organic carbon content occur in southern Brazil. The study collected 135 soil samples to determine organic carbon content, soil classification, and geomorphological variables derived from the digital elevation model SRTM 30m. The investigation found that the environments where Organosols occur have higher altimetry values than the places where Cambisols predominate. The analysis also observed variations in the maximum values of slope between the environments of occurrence of the Organosols and Cambisols evaluated. The results demonstrate the potential of environmental variables related to geomorphology to characterize and identify environments that are more favorable to the occurrence of soils with high levels of organic carbon in southern Brazil, remotely and with reduced costs associated with collecting data in the field and in hard-to-reach areas.

DAEMONS AND GENIUS: ON THE PLACE OF THE GENIUS IN SCIENCE AND PHILOSOPHY ACCORDING TO KANT, GOETHE, AND HEGEL
Authors:   Johns Hopkins University, Chaput Emmanuel
Published: February 2025

In this paper, I discuss Hegel’s reception of Goethe’s theory of colors and attempt to
shed light on its philosophical significance for Hegel. I start with an overview of the central
themes and concepts in Goethe’s theory, focusing in particular on primordial phenomena,
polarity, intensification, complementarity of colors, and Goethe’s anti-reductionism. I then argue
that it is especially the principle of polarity, as well as Goethe’s anti-reductionism about the
domain of color phenomena, that were attractive for Hegel and played the most significant role
in his discussion of Goethe’s theory. Finally, I argue that Hegel’s interest in polarity is connected
with his view that this principle anticipates, in a sensuous and not fully adequate way, his own
account of the concept as the fundamental structure of reality.
CRITICA PSIHOLOGIEI RAŢIONALE ŞI PARALOGISMUL PSIHOLOGIC
Authors:   Institutul de filosofie și psihologie „Constantin Rădulescu-Motru” al Academiei Române, Croitoru Rodica
Published: February 2025

In his Critique of Pure Reason, Kant contributes to the critique of rational psychology by highlighting the intensive size of the soul and arguing that it is responsible for the degree of reality of the faculties of the soul and for existence in general. This degree may progressively decrease to nothing. This way, a substance can be transformed into nothing, not by decomposition, but through a gradual loss of force. This observation proved to be consonant with further clinical and empirical observations about the human being and about its vital capacities. At the same time, it contributed to the decline of psychology as a general science of the human soul, particularly by changing the focus on different aspects of the I/soul/psyche in relationship with human life.

The thesis of this paper is that there is a fundamental, metaphysical dimension of Brentano’s philosophy that in no way allows itself to be reduced to his image as a representative of Austrian philosophy. This image is a result of a positivist-sceptical interpretation of his philosophy characterized by the following features: (i) the emphasis on the fourth habilitation thesis and the methodological monism specific to it; (ii) the elimination from philosophical discourse of problems that cannot be dealt on the basis of experience and scientific method; (iii) the focus on Brentanian psychology, without paying attention to its metaphysical dimension and, in general, to the philosophical discipline of metaphysics; (iv) the fact that it operates with only one meaning, the modern one, of the phrase “purely theoretical interest”, without the slightest suspicion that Brentano also operates with another meaning of the term, the traditional one. In this way, this interpretation risks turning his philosophy into a philosophy of the skeptical phase of decline. Unlike this thesis, the present study distinguishes between the two meanings of theoretical interest and, on the basis of the traditional meaning of it, reconstructs Brentanian philosophy as the philosophy of a new philosophical ascending phase at the end of the 19th and the beginning of the 20th century. In this manner, both the importance of the metaphysical dimension of Brentano’s thought and the consequences resulting from this for the correct establishment of the relations between his thought and other philosophical trends of that time, including positivism, are highlighted.
Plant dehydrins. General characteristics and hypothetical functions
Authors: Rudacova Angela , Cherdivara Ala , Rudacov Serghei
Published: February 2025

Stress proteins - dehydrins are a family of proteins characterized by high hydrophilicity and thermal stability. They belong to LEA (Late Embryogenesis Abundant) class II proteins, The structural features of dehydrins include the presence of conservative sequences in them, which were designated as K-, S-, Y-, F- segments, while the presence of a K-segment is mandatory for all dehydrins. The number and combination of K-, S-, Y- and F- segments formed the basis for the classification of dehydrins, which made it possible to distinguish six classes of dehydrins: YnSKn, Kn, KnS, SKn, YnKn and FnSKn. It is assumed that dehydrins can prevent the denaturation and coagulation of proteins during dehydration; they are able to bind a significant amount of water, preventing its loss. One of the putative functions of dehydrins is their ability to participate in detoxification from excess salt ions. Some of the dihydrins have antifreeze activity.

Authors: Sampaio Junior Adonias da Silva
Published: February 2025

Objetivo: Identificar as intervenções utilizadas no manejo da ansiedade de pacientes na fase pré-operatória de cirurgia de neoplasia cerebral. Método: Revisão integrativa, realizada nas bases de dados Embase, Lilacs, PubMed/MEDLINE, Scielo, Scopus e Web of Science, em fevereiro de 2024. Os critérios de elegibilidade incluíram estudos completos, publicados nos últimos 10 anos e disponíveis gratuitamente, em inglês, português ou espanhol. Foram excluídos os estudos que não se concentraram na fase pré-operatória e que incluíram população abaixo de 16 anos. Resultados: Foram encontrados um total de 7.738 artigos, sendo incluídos apenas 10 artigos na amostra final. As principais intervenções encontradas foram categorizadas em farmacológicas – flupirtina e pregabalina; e não farmacológicas – cuidados holísticos, acupuntura, intervenção musical, realidade virtual, enfermagem perioperatória, comunicação médico-paciente e abordagem centrada no paciente. Conclusão: Diferentes intervenções vêm sendo utilizadas para o manejo da ansiedade pré-operatória em pacientes com neoplasia cerebral, com destaque para as não farmacológicas, que tem tido maior adesão e apoio devido ao custo-benefício, por serem minimamente invasivas e apresentarem baixo risco de efeitos adversos. Ainda assim, novas pesquisas são necessárias para ampliar as opções de intervenções com esta população.
Application of Restorative Justice in Cases of Domestic and Child Violence
Authors: Fatin Hamamah
Published: February 2025

Restorative justice (RJ) is an alternative approach to resolving criminal cases that focuses on victim recovery, perpetrator rehabilitation, and community reintegration. In the context of domestic and child violence, this approach offers the potential for a more inclusive and sustainable resolution compared to traditional retributive approaches. However, there is debate about the effectiveness of RJ in cases of violence that have profound psychological and physical impacts on victims. The issue at hand is whether RJ can provide adequate justice without reducing legal protection for victims. This study offers novelty by examining the application of RJ in cases of domestic and child violence in Indonesia, where RJ laws and policies are still developing. The purpose of the study is to identify the challenges and opportunities for implementing RJ in these cases and to evaluate the extent to which this approach is able to create restorative justice for victims and perpetrators. This study uses a qualitative method with case studies on several cases of domestic and child violence resolved through RJ in various regions. The findings indicate that RJ can be effective in facilitating victim recovery, but its implementation requires a strong support structure, including professional counselors and clear legal protection. The conclusion of this study confirms that RJ has great potential in resolving domestic violence cases, but its implementation must be carried out carefully to ensure justice and protection for victims. The implication is that this study encourages policy makers to design a more comprehensive and inclusive RJ framework in handling domestic violence.

Agriculture plays a pivotal role in the Philippine economy, particularly in rural areas, where a significant portion of the population relies on it for livelihood. However, the sector faces challenges related to low productivity, climate change, and limited access to modern technology. This study investigates the impact of applying Big Data technology in enhancing agricultural productivity and sustainability in rural Philippines. The urgency of this research is underscored by the need to address food security concerns, optimize resource utilization, and improve the income of smallholder farmers. Traditional farming practices often fall short in meeting these objectives, necessitating innovative solutions. The research methodology involves the implementation of Big Data technology for data collection, analysis, and decision-making in agriculture. Remote sensing, sensor networks, and data analytics are integrated to monitor soil conditions, weather patterns, and crop health. Farmers receive real-time information and recommendations through mobile applications, enabling them to make informed decisions on irrigation, fertilization, and pest control. Through a series of field trials and surveys, this study evaluates the impact of Big Data technology on crop yield, resource efficiency, and income generation. Additionally, the research assesses the social and economic implications, including the empowerment of rural communities, job creation, and market access improvement. The findings reveal that the application of Big Data technology significantly enhances agricultural productivity in rural Philippines. Crop yield increases, resource use efficiency improves, and farmers' income rises. Moreover, the technology fosters resilience against climate change effects, as adaptive measures can be promptly implemented. The adoption of Big Data technology in agriculture not only benefits farmers but also contributes to national food security and economic growth. This research serves as a model for sustainable agricultural development, emphasizing the potential of technology-driven solutions in addressing the challenges faced by rural communities.
