The Relative Moisture Sensitivity of Compression as Compared to Tensile Strength
Authors:   Swedish Forest Products Research Laboratory, Back Ernst L.
Published: March 2024

The moisture sensitivity of compression and tensile strength is compared for a range of packaging papers. It is shown that compression strength falls off more rapidly with increasing moisture content than tensile strength. This is especially true in the range up to 10% moisture content, where there is little effect of tensile strength. Results were obtained using the STFI short span compression test and tensile test carried out in silicone oil. Also included are Concora Medium Tests (CMT) for fluting. Concora Liner Tests (CLT) for liner and Ring Crush Tests (RCT) for compression. This difference in moisture sensitivity is also very evident for papers which have been given different wet strengthening treatments. For example, after 60 min. of water immersion, such wet strength papers can retain a wet tensile strength which amounts to 30 – 40% of the 50% RH value. The corresponding wet compression strength retention is only 15% to 25%. It is also shown that the tensile stiffness is more moisture sensitive than the tensile strength. The results are discussed with reference to the glass transition that cellulose and hemicelluloses at 20 degrees C pass through at a given moisture content corresponding to about 10% moisture content for a kraft paper. This transition particularly affects the moduli of the paper, while for tensile strength thermal softening apparently also has some positive effect, by reducing stress concentration.

Published: March 2024

Bloodstream infections pose a significant threat to patients undergoing hemodialysis, leading to hospitalizations, increased morbidity, and mortality. The Centers for Disease Control and Prevention (CDC) has prioritized the prevention of bloodstream infections in hemodialysis through their Making Dialysis Safer initiative.Most bloodstream infections linked to vascular access primarily occur in patients undergoing dialysis using central vein catheters. The Centers for Disease Control and Prevention (CDC) advocates core interventions as the best practices for catheter care in hemodialysis, demonstrating their effectiveness in reducing catheter-associated bloodstream infections. However, bloodstream infections linked to hemodialysis catheters persist at undesirable levels, it is likely due to failures in maintaining rigorous aseptic techniques or other factors beyond the scope of the CDC's core interventions. There is a urgent need for innovation of preventive measures. This review focuses on the current therapies, recent developments and also addresses potential drawbacks and adverse effects associated with thealternatives. This review also highlights the challenges and future perspectives which might prove to be beneficial in reducing infection rates in hemodialysis patients.
The impact of the war on Ukraine's foreign trade
Authors:   National Aviation University, Ukraine, Simakhova Anastasiia
Published: March 2024

Abstract The article considers theoretical and practical aspects of the war's impact on Ukraine's foreign trade. The choice of the topic is due to the need to find new ways to minimize the negative impact of the war on the country's foreign trade. In the article, general scientific methods were used: methods of synthesis and analysis; data systematization and comparison; and SWOT-analysis. The information base of this article consisted of statistical data of the State Statistics Service of Ukraine, articles by scientists, and Internet sources. The article analyses the changes in the structure of foreign trade in goods in Ukraine in 2022 compared to 2021. An analysis of changes in the regional structure of Ukraine's foreign trade is carried out. It was found that the exports of Vinnytsia, Volyn, Zakarpattia, Lviv, Odesa, Rivne, Ternopil, Cherkasy, and Chernivtsi regions in 2022 were higher than in 2021. These regions concentrated significant export potential during the war. The main destructive factors of Ukraine's foreign trade development during the war were identified. These factors are: decrease in export and import volumes; negative foreign trade balance; logistical problems, restrictions on the movement of goods, destruction of infrastructure. It is predicted that as a result of the war, the commodity structure of production in Ukraine will change, preference will be given to defense industries. Recommendations for the Ukrainian government to minimize the negative effects of the war on Ukraine's foreign trade are proposed, including: tax benefits for Ukrainian entrepreneurs, support for small and medium-sized enterprises, diversification of product sales markets, development of the domestic market and stimulation of domestic consumption, promotion of high-tech exports, reconstruction and restoration of the infrastructure of Ukraine, etc. The scientific novelty of the article lies in the improvement of ways to minimize the negative impact of the war on Ukraine's foreign trade. The practical value of the article lies in the development of relevant recommendations. It is established that the development of foreign trade in Ukraine will contribute to the stabilization of the national economy and ensure economic growth in the post-war period.

OBJECTIVE

To test efficacy of a parent-delivered multidomain early intervention (Learning through Everyday Activities with Parents [LEAP-CP]) for infants with cerebral palsy (CP) compared with equal-dose of health advice (HA), on (1) infant development; and (2) caregiver mental health. It was hypothesized that infants receiving LEAP-CP would have better motor function, and caregivers better mental health.

METHODS

This was a multisite single-blind randomized control trial of infants aged 12 to 40 weeks corrected age (CA) at risk for CP (General Movements or Hammersmith Infant Neurologic Examination). Both LEAP-CP and HA groups received 15 fortnightly home-visits by a peer trainer. LEAP-CP is a multidomain active goal-directed intervention. HA is based on Key Family Practices, World Health Organization. Primary outcomes: (1) infants at 18 months CA: Pediatric Evaluation of Disability Inventory-Computer Adaptive Test (PEDI-CAT mobility); and (2) caregiver: Depression Anxiety and Stress Scale.

RESULTS

Of eligible infants, 153 of 165 (92.7%) were recruited (86 males, mean age 7.1±2.7 months CA, Gross Motor Function Classification System at 18 m CA: I = 12, II = 25, III = 9, IV = 18, V = 32). Final data were available for 118 (77.1%). Primary (PEDI-CAT mobility mean difference = 0.8 (95% CI −1.9 to 3.6) P = .54) and secondary outcomes were similar between-groups. Modified-Intention-To-Treat analysis on n = 96 infants with confirmed CP showed Gross Motor Function Classification System I and IIs allocated to LEAP-CP had significantly better scores on PEDI-CAT mobility domain (mean difference 4.0 (95% CI = 1.4 to 6.5), P = .003) compared with HA.

CONCLUSIONS

Although there was no overall effect of LEAP-CP compared with dose-matched HA, LEAP-CP lead to superior improvements in motor skills in ambulant children with CP, consistent with what is known about targeted goal-directed training.

Las infraestructuras: el soporte de los territorios urbanos. Aproximaciones para la conformación de un manual para la enseñanza de las infraestructuras territoriales a nivel superior. Estrategias de aprendizaje activo para la vida
Authors: Padilla Etienne Patricia Elizabeth
Published: March 2024

El análisis de las infraestructuras en una ciudad permite determinar su nivel de competitividad, pero también identifica la conciencia de los ciudadanos en el cuidado del medio ambiente, del territorio y de los recursos naturales existentes. Tomar en cuenta a las infraestructuras en el análisis de las problemáticas urbanas permite la adecuada planeación y el ordenamiento territorial, y así garantizar una vida de calidad con miras hacia el futuro. La formación actual de los estudiantes de nivel superior necesita un abordaje innovador y colectivo a partir de una serie de técnicas didácticas que provocan el razonamiento, el debate, la elaboración de proyectos de diagnóstico aplicable, la comprobación de hipótesis elaboradas en clase y propuestas conceptuales de solución. El método de aprendizaje diseñado para la enseñanza de las infraestructuras, está relacionado con las nueve teorías más influyentes de la UNESCO, de las cuales se retoma a Piaget y a Vygotsky con la idea de formar al alumno no sólo como receptor pasivo de la información, sino como un participante interrelacionado con los usuarios de la ciudad, y creador de nuevas estructuras mentales en un contexto actual determinado; la experimentación social, las inteligencias múltiples y las habilidades del siglo 21, darán a los estudiantes una visión integral en su formación general. El objetivo de este artículo es mostrar el proceso activo a través de estrategias de aprendizaje innovador aplicables a la realidad y al entorno en el que vivimos.

A Study on the Dong-A Ilbo’s “Romance in History” Series to Expand Minority Readership
Authors:   Academy of Mobility Humanities, Center for Asia & Diaspora Studies, f f
Published: March 2024

This paper is a study that reveals the literary historical significance of the planned serialization “Romance in History” of the Dong-A Ilbo and the subsequent serialization “Children’s Chosun.” In this regard, based on a series of surveys on newspaper serials, including “Romance in History,” Kang Mi-Jung tried to reveal the function of private painting during this period and link it with the development of historical literature theory. Taking the achievements and limitations of the preceding studies as a starting point for discussion, this paper attempted to reconsider the literary and historical status of the series “Romance in History.” In order to derive the practical basis, this paper analyzed the text from the background of the appearance of “Romance in History,” the actual status of the series, and the level of formal aesthetics. As a result, it was verified that “Romance in History,” which was greatly welcomed by the public, was a genealogical precedent that suggested a motif for the creation of historical novels in the newspaper series entering the prosperity of the 1930s. It was also confirmed that it was the background and test that inspired the creation of historical novels.
A Cross-Section of Korean People’s Thoughts on the Immobility Situation Caused by the COVID-19 Pandemic
Authors:   Academy of Mobility Humanities, Center for Asia & Diaspora Studies, f f
Published: March 2024

The COVID-19 pandemic created an immobility situation that was not just a quarantine issue, but formed meta-discourses in all areas related to human life, including politics, economy, diplomacy, education, and culture. Even in the urgent situation of these meta-discourses in which nations had to decide on their future, discourses existed about daily life and the unusual lives of individuals caused by the COVID-19 outbreak. To record the testimonies of that era, the Mobility Humanities Education Center at Konkuk University has collected writings on life changed after the outbreak of the COVID-19 pandemic, which were written by middle and high school students, college students, and ordinary citizens. This paper attempts a narrative analysis of the 51 essays to explore how Koreans are influenced by meta-discourses, to examine that era, and make suggestions for the future.
Was Kore/Persephone's journey to the afterworld as a path to infertility?
Authors: Pedrucci Giulia
Published: March 2024

As mythological figures, Demeter and Kore stand together as timeless symbols of this moment of transition between maidenhood, wifehood, and then motherhood. While contemplating these goddesses, historically situated and embodied women surely remembered — or learned soon enough — that pregnancies and babies would follow their marriage. The mythological narrative, however, focuses on this crucial transition rather than on the effective beginning of motherhood through pregnancy and childbirth. Kore is the maiden, the new bride, and the mother-to-be. She never becomes a mother.

The absence of offspring can be explained by the functional reading we just mentioned: she is a mother-to-be, not a mother. Demeter, in the Eleusinian myth, plays the role of the mother. There is, however, another way that can be explored in this regard and that is not necessarily in contrast with the first one: Kore/Persephone's marriage is sterile since it takes place in the underworld. There is no life in the afterworld; therefore, she can not give birth to a child. This paper will explore if the journey of Kore/Persephone to the Hades can be seen as a path to infertility.
Hell on earth: Penelope's underworld journey and Nekyia
Authors: Quartarone Lorina
Published: March 2024

By presenting Penelope's experiences and traits as parallel to those of Odysseus, the text of the Odyssey depicts her as heroic in her own right. This detailed analysis of Penelope's life in the palace on Ithaca – depicted as an Underworld-like realm of suspension – shows how similar her experiences, traits, actions and reactions are to her husband's; the text furnishes multiple similes and epithets that demonstrate these parallels. The suspension of progress on Ithaca during the suitors' presence, in addition to Penelope's and others' declarations that Odysseus is dead, instills the palace with an atmosphere of death; in effect, this represents Penelope's katabasis. When she converses with her “dead” husband, she learns in this nekyia – as Odysseus learns during his – what she needs to know to move forward. This article offers an in-depth look at the language, similes, and epithets that portray Penelope's life and experiences in the palace as well as her crucial encounter with Odysseus in book 19, where the suspension and liminality reach their peak.
Effects of organic degradation products on the migration behaviour of radionuclides in cementitious materials
Authors: Ait-Mouheb Naila , Macé Nathalie , Henocq Pierre , Bosbach Dirk , Deissmann Guido
Published: March 2024

The impact of phthalates, which might be present in a cementitious repository as degradation products of superplasticisers or PVC additives, on the migration behaviour of An(III)/Ln(III) was investigated in batch sorption experiments on hardened cement paste. In the absence of organics, An(III)/Ln(III) sorb strongly on HCP with distribution ratios, Rd, of 105 to 106 L kg−1. Above a no-effect level of ~ 10–3 mol L−1 phthalate, a distinct decrease of the An(III)/Ln(III) sorption was observed with sorption reduction factors (i.e., the ratio between the Rd values without and with organic ligand) of 100 to 1000 at phthalate concentrations of 10–1 mol L−1. This sorption reduction is attributed to the effect of Ca complexation with phthalate on the stability of calcium silicate hydrate (C–S–H) phases as main sorbing phase. These results and ongoing diffusion experiments indicate an increase in the mobility of An(III)/Ln(III) in cementitious barriers with increasing phthalate concentrations.

Managing the Efficiency of Business Processes in Well Workover of an Oil-Producing Enterprise
Authors:   Kalashnikov Izhevsk State Technical University, Simchenko Olga , Ershova Irina ,   Ural Federal University named after the first President of Russia B.N. Yeltsin, Chazov Evgeny ,   Kalashnikov Izhevsk State Technical University
Published: March 2024

This work is devoted to the study of the principles and approaches to evaluating the efficiency of business processes carried out by the well workover department of an oil-producing enterprise. According to statistics, service production is a major source of enterprise costs. It accounts for 30–50% of all operating costs. Due to the fact that the majority of large oil fields in Russia are at the final stage of development (more than 70%), the largest share in the composition of operating costs is services for well workover. Accordingly, the purpose of the study was to substantiate the theoretical provisions for managing the efficiency of business processes in the well workover of an oil-producing enterprise and to develop practical recommendations for their implementation. The paper focuses on the main approaches to assessing the efficiency of enterprises as well as the problems that arise when solving problems with the presented approaches due to their inconsistency with new economic challenges. The introduction of changes accompanying the transformation of such approaches made it possible to develop a new management system based on the implementation of the principles of improving the efficiency of business processes in well workover. This, in turn, led to the development of a methodology for a comprehensive assessment of the efficiency of business processes being implemented, which makes it possible to integrate with the concept of managing the efficiency of an oil-producing enterprise.
Investigation of the Influence of Climatic Factors on the Rate of Decomposition of Forest Litter
Authors:   National Aerospace Agency, Tahmazov Tabriz
Published: March 2024

The decomposition of the litter changes its indicators under the influence of climatic changes. Taking into account the impact of this process on the global carbon cycle, the decomposition process is a feedback affecting future climate change. The special role of the litter decomposition process in the overall carbon cycle on a regional and global scale determines the importance of studying the regularity of the influence of climatic parameters on the rate of decomposition of forest litter. Known approaches to solving this problem are based on a probabilistic analysis of the relationship between climatic factors. It is indicated that the task of determining the relationship between temperature and soil moisture when assessing their joint impact on the decomposition rate of forest litter can be formulated in a slightly different way. From the point of view of the ecology of the forest ecosystem, the following statement of the problem is no less interesting: under what relationship of these factors can the decomposition rate reach extreme values? The author proposes a representation of the problem being solved in the form of an extreme problem, taking into account some restrictive conditions imposed on the desired function of the relationship between temperature and soil moisture. The proposed new approach to solving the problem of the influence of climatic factors such as soil temperature and humidity, which consists of calculating the conditions leading to an extremum of the decomposition rate of forest litter, allows us to determine the function of the relationship between these factors and the point at which the decomposition rate reaches a peak. The solution to the problem allowed us to calculate the optimal type of the studied relationship, at which the rate of decomposition of the forest litter reaches an extreme. The results of the study can be used in modeling the processes of the influence of climatic factors on the overall carbon cycle of the forest ecosystem
The Influence of Climatic and Hydrological Changes on the Forest-Growing Conditions of the River Floodplains of the Don Basin

The article deals with the problem of floodplain forest degradation in the steppe zone, using the Don basin’s rivers as an example. The floodplains of the Khoper, Buzuluk, Ilovlya, Medveditsa, and Chir rivers were the key objects of the study. Identification of the landscape-hydrogeological conditions of river floodplains was carried out using the profiling method. In total, five transverse landscape profiles were laid in the floodplains of the listed rivers, along which leveling was carried out to build a hypsometric profile and a comprehensive soil and plant description. For the arid zone rivers, ground feeding is an important source of moisture in addition to atmospheric. Therefore, one of the main tasks was to determine the groundwater level using subsurface sounding (georadar). The analysis of the maximum levels of data for spring floods showed a trend of decreasing the height of floods since the late 1990s. Comparison of these data with the hypsometric profile and radar survey data revealed that the provision of complete flooding of floodplains occurs once every 10–20 years. The absence of annual complete flooding of floodplains with water has led to a decrease in the groundwater level to 5–6 m, which is an unfavorable factor for the development of woody vegetation. The climatic and hydrological conditions of the steppe zone considered in the article are unfavorable for the development of woody vegetation since they do not correspond to the conditions of its initial formation. In view of the existing conditions and the identified trends in the reduction of floods and the fall of the groundwater level, it is possible to predict a further reduction and redistribution of the forest cover of the Don basin’s river floodplains.
Immanence and Differentiation in Spinoza
Authors: Stephano Oli
Published: March 2024

This paper argues that ontological immanence involves but is not reducible to substance monism. Attending to immanence in Spinoza’s ontology, I provide a creative exegesis of the defining features of Spinoza’s immanent ontology, arguing that it recasts the concept of substance itself, from a term of transcendence and totalization to one of immanence and differentiation. In critical conversation with Deleuze’s influential reading, I identify five interconnected features which, taken together, elaborate Spinoza’s ontology of immanence: substance monism, univocity of attributes, immanent causality, the identification between G-d and Nature, and the status of finite modes as explications of substance rather than its extrinsic effects. I argue that, taken together, these features refashion the concept of substance, such that substance becomes not a term of totalization but rather one of ongoing production of diversity. Attending to the role of finite modes in this ontology, I emphasize the ways in which immanence can lend force to vital reconfigurations of ethical and political life: by defining beings and systems in terms of their capacities, which are augmented, diminished, or maintained depending on how they converge in relation.
The Plantation Complex in the Colony of Puerto Rico: On Material Conditions
Authors: Zambrana Rocío
Published: March 2024

This essay develops a loosely understood Marxist notion of material conditions in light of the Caribbean plantation complex. The racial order endemic to the plantation and its continuation in post-emancipation contexts undermines any spurious base/superstructure distinction at work in an understanding of material conditions even in some accounts of racial capitalism. Material conditions are as ideological as they are “infrastructural” (Sylvia Wynter) in being ongoingly articulated by anti-black coordinates of sense. The ongoing actualization of the racial order of slavery is understood not as required by altered material conditions, but rather as altering material conditions. The essay considers the continuity of the racial order of the plantation through the contract in a specific site, namely, post-emancipation Puerto Rico.
Lady Chandos and the Humanity Function: Reading the Postscript to J. M. Coetzee’s "Elizabeth Costello" with Lacan and Badiou
Authors: Hile Fiona
Published: March 2024

Badiou has said that his entire philosophical project stems from the need to “update” the traditional philosophical categories of Truth, Being, the Infinite and the Universal in the wake of the 19th Century German mathematician Georg Cantor’s explication of transfinite set theory. In his essay, “What is Love?”, he provides an account of one of the ways in which a post-Cantorian reconfiguration of the ontological status of the category of Woman might operate. This is given in the form of a postscript subtitled “The Feminine Position and Humanity” wherein he gives Lacan’s conception of supplementary feminine jouissance “an extra turn of the screw”. This essay draws on Badiou’s reconfiguration of the philosophical category of Woman to examine the implications of another postscript, that which abruptly concludes the 2003 novel Elizabeth Costello by J. M. Coetzee. It reads Coetzee’s invention of the “Letter of Elizabeth, Lady Chandos” with recourse to Lacanian psychoanalytic theory and on through the ontological reconfiguration of the philosophical category of Woman demonstrated by Badiou. It argues that Coetzee assembles, through the intervention of the postscript, a situation that “makes it possible to argue”, along with Badiou, that, for the woman position, love knots together the four types of truths – Politics, Art, Science, and Love (2008, 196).
A Footnote on Alain Badiou’s Critique of Plato’s "Sophist"
Authors: Murillo Keylor
Published: March 2024

In his second book on being and event, Logics of Worlds, Alain Badiou describes Plato’s late dialogue, The Sophist as “one of the first transcendental inquiries in the history of thought”. In this dialogue, Plato introduces what he calls the Idea of the Other, the possibility of a being of non-being, an inevitable break with the Parmenidean tradition. However, according to Badiou, Plato fails to provide an example of how this Idea of the Other can manifest itself or be effective in a world, or in other words, appear. This paper argues that not only there is such an example in Plato’s Sophist, namely, the phantasma, but also that it can be strongly related to Badiou’s philosophical system.

Abstract This study aimed to understand the perception of young adults and middle-aged adults about functional foods and to relate it to socioeconomic, health, and consumption factors. The study participants, both male and female adults (n = 522), completed two questionnaires. The first questionnaire addressed socioeconomic and health aspects, which were designed by the researchers. The second questionnaire focused on attitudes related to the consumption of functional foods, evaluating consumers' perceived needs, benefits, confidence, and safety. The results demonstrated that adults hold a positive perception of functional foods, acknowledging their benefits and the need for consumption. However, there is some skepticism regarding the credibility of functional food claims. Income and education level appear to be factors that influence adults' perception of functional food consumption. Middle-aged adults (45 to 65 years) tend to perceive functional foods as medications, while young adults (18 to 44 years) who consider nutritional quality important when choosing food for consumption tend to have a better perception of functional foods. The recognition of the benefits and the need for functional foods indicates that this market remains promising. However, measures to instill greater consumer confidence should be adopted.
ARTICLE-OPINION: SCIENTIFIC BIOGRAPHY AS POSSIBILITY TO VALUE A MORE FEMININE AND BLACK CHEMICAL SCIENCE
Authors: CORDEIRO MARINÊS DOMINGUES
Published: March 2024

ABSTRACT: In this paper, I present the evaluation process of the article “Scientific biography as possibility to value a more feminine and black Chemical Science” through an analysis of its axiological, methodological, factual, and historiographical domains. In axiological terms, I present the evidence and the train of thought that led me to understand that the paper, despite being intended as an exploratory research, demonstrated a previous hypothesis, that the biography of a black female scientist could promote discussions about race and gender in teacher training. In the methodological domain, I explore the inconsistencies that this previous hypothesis had for the development of the methodology. In the factual domain, I discuss the importance of presenting data classified by gender, race, and geographic location. When it comes to history and historiography, I present the discussions with the authors regarding the construction of teaching material that was not presented to me in the first version. I close the work by indicating that the final version has become more coherent and its hypothesis has been attenuated. The work presents above average quality and methodological rigor, in my opinion, and the process was extremely interesting, generating pertinent questions to our area of research as a whole.

Abstract Advance directives allow patients to assign a legal representative and express their wishes to be fulfilled when they can no longer communicate. This study evaluated cancer patients’ knowledge and preferences regarding these directives. A cross-sectional quantitative research was conducted by filling out two advance directive models and a questionnaire. Of the total sample, 87.38% had never heard of such document, 97.2% ignored the two models available and 95% had no difficulties filling it out. After clarifications, 93.46% considered it important for all patients to write a directive, 94.86% expressed that advance directives should be made available to patients and 91.12% argued that a federal law should be passed. Explaining the concept of advanced directives increased the interest of cancer patients in exercising this right which strengthen their autonomy.
Secreto profesional en la relación médico-paciente: conocimientos de los estudiantes de medicina
Authors: Soares Aurélio Almeida Santos , Batista Cláudia Bacelar
Published: March 2024

Resumen La relación entre el médico y el paciente debe basarse en parámetros que garanticen la autonomía y la libertad a ambos. Entre estos parámetros se destaca el secreto profesional, que es un derecho esencial del paciente y una obligación del médico. Este estudio evaluó los conocimientos de los estudiantes de medicina sobre el secreto profesional mediante la aplicación de un cuestionario a 409 estudiantes de primer a cuarto año de la carrera. La comparación entre la mediana de correspondencia y las respuestas esperadas dio como resultado que el primer año obtuvo puntuaciones más bajas en las situaciones problemáticas. Se concluyó que existe una diferencia en el nivel de conocimientos entre los años del grado y que evoluciona en el segundo año, manteniéndose en la misma proporción hasta el cuarto.
Advanced directives as perceived by healthcare professionals
Authors: Barbosa Anne Karolyne Santos , Lisboa Walter , Vilaça Anali Póvoas Orico
Published: March 2024

Abstract Advance directives are instruments that aim to ensure the fulfillment of patients’ will in circumstances where they are unable to express themselves freely. This study investigated how health professionals perceive the use of this tool in palliative care, as well as the main ethical dilemmas and gains or losses related to it. Semi-directed interviews were conducted with nine professionals and the data underwent content analysis. Five categories emerged, pointing to a good reception of the resource, as it ensures patient autonomy, strengthening the perception of care, facilitating decisions and providing psychological comfort. On the other hand, the adversities or challenges involved the need for better technical preparation and greater team integration, professional overload, legal uncertainty about its use, end-of-life as a taboo and society’s lack of knowledge about the subject.

Authors: Silva Alessandra Ribeiro da , Melo Ana Júlia Bonine de
Published: March 2024

Resumen El final de la vida requiere un enfoque amplio, con alivio del dolor físico, emocional, familiar y social. Además, las cuestiones espirituales deben abordarse como forma de ofrecer confort al paciente. En este contexto, esta revisión narrativa de la literatura tiene como objetivo discutir los efectos de la espiritualidad/religiosidad en los cuidados paliativos. A partir de una búsqueda de artículos en PubMed y en la Biblioteca Virtual de Salud, se seleccionaron 11 artículos para la revisión. Los debates se dividieron en tres ejes: espiritualidad de los pacientes terminales, espiritualidad de los profesionales sanitarios y espiritualidad de los familiares. Se concluye que las prácticas espirituales durante el final de la vida y en el afrontamiento de la angustia son cruciales tanto para los pacientes y sus familias como para los profesionales de la salud.
Tomada de decisão compartilhada enquanto estratégia para vulnerabilidade em saúde
Authors: Aguiar Natália
Published: March 2024

Resumo A premissa de que todo ser humano é vulnerável por natureza advém da noção de vulnerabilidade enquanto suscetibilidade ao dano, assim como da inter-relação e interdependência intrínseca do ser humano com seu contexto socioambiental, cabendo à sociedade estabelecer instituições capazes de promover tanto a proteção quanto a autonomia das pessoas, em equidade de condições. Para além do dever profissional de informar benefícios e malefícios das intervenções possíveis, incluindo as consequências de negar qualquer intervenção, o cuidado centrado no paciente integra uma abordagem colaborativa que considera fundamental a tomada de decisão compartilhada. A partir de uma revisão teórica, neste artigo analisa-se o conceito de vulnerabilidade e sua relação com o respeito e a promoção dos direitos humanos dos pacientes, propondo e justificando a tomada de decisão compartilhada no que se refere a uma boa estratégia de mitigação de vulnerabilidades acrescidas.
Bioethics teaching in dentistry as seen by course coordinators
Authors: Colodette Renata Maria , Gomes Andréia Patrícia , Moreira Tiago Ricardo
Published: March 2024

Abstract This article analyzes the importance dentistry course coordinators attribute to bioethics teaching and their opinion on the expected graduate profile. An exploratory, descriptive cross-sectional study was conducted with 130 coordinators of Brazilian dentistry courses. Data underwent descriptive analysis and Bardin’s content analysis. Most participants attribute importance to bioethics teaching in different situations and 23.8% considered a professional with an ethical and humanized attitude, who is reflective and technically competent as a suitable profile. Dentistry courses are increasingly including bioethics in their curricula, and although most coordinators consider it important, not all understand its principles.
Side-by-Side Testing of Grit Separation Units
Authors: D Jolis , A Velasco
Published: March 2024

Two grit removal systems were tested side-by-side for the treatment of wastewater from a combined-sewer system. The two units were operated at constant flows and variable grit loads ranging from 1.2 to 745 Kg/m3 /h that covered the typical range of dry and wet weather conditions experienced at the treatment facility. The average mass grit removal for the multi-tray free vortex unit was 92.6% and it was 85.4% for the forced vortex system. Both units consistently failed to remove particles with sand equivalent sizes, which their respective overflow rates would otherwise predict. This observation can be explained by uneven force distributions over non-spherical grit particles with lumpy grease deposits and variable curvature that effect motion traverse to flow, increase buoyancy and cause particle lift.
