A Basic Outline on Engineered Cementitious Composites
Authors: Ramu Muthuminal , Mohana Priya R.
Published: April 2024

Concrete is a commonly utilized construction material in the engineering field. The low tensile strength and strain capacity of conventional concrete is a significant barrier to its actual integration in infrastructure. Cementitious composite is a combination of different materials that, when combined, form a composite that aids in the bonding of different components in a structure. It is a primitive combination that is still used in the construction industry. In contrast to brittle concrete, engineered cementitious composite exhibits high tensile strength with robust strain-hardening performance and multiple self-controlled crack. ECC could be used in any structural component in a building or structure because of its ability to be moulded into any shape. This emphasis the important role of engineered cementitious materials, and thus, in this chapter, the evolution of ECC materials and structures, including their characteristics, different kinds, and applications, will be thoroughly detailed, ranging from experimental investigations to enhanced numerical modeling methods and techniques.

Published: April 2024

Engineering cement composites (ECC) are a type of fiber cement composite material and possess high mechanical and durability properties. The main objective of this study is to develop a model for the relationship between compressive strength and split tensile strength. To develop these relationships, mechanical properties that are available in the literature for various types of ECC are collected in which 75% data is used for training and 25% for testing purpose. The study is further extended to check the relationships or models available in the standards, codes, and in literature for various mechanical properties are also evaluated. Sensitive assessment is performed to evaluate the new model developed for ECC based on mechanical properties. These relationships are required for designers, engineers, researchers, and academicians when one of the mechanical properties are not available for design purpose.

Representações sociais e educação: um estudo sobre teses e dissertações no período de 2016 a 2018 no Paraná-Brasil
Authors: Ogliari Cassiano Roberto Nascimento , Ens Romilda Teodora , Pullin Elsa Maria Mendes Pessoa
Published: April 2024

Essa pesquisa tem como objetivo mapear as teses e dissertações produzidas em Programas de Pós-Graduação em Educação (PPGEs), com o aporte da TRS, em universidades paranaenses, no período de 2016 a 2018, bem como compreender se elas contemplam possibilidades teóricas e metodológicas da TRS. Por meio de uma pesquisa do tipo ‘estado do conhecimento’, utilizamos as ferramentas de buscas disponíveis no Catálogo de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), com o descritor/expressão ‘Representações Sociais’. Os resumos foram submetidos ao processamento de análise textual pelo Iramuteq: nuvem de palavras, análise de similitude e classificação hierárquica descendente. Os resultados foram analisados com base na hermenêutica filosófica (Gadamer, 1998), que permitiu realizar interpretações e inferências com o aporte teórico da TRS (Moscovici, 1978; 2003). Da análise lexical, destacam-se professor, estudo e escola, cujo foco incide sobre o professor, o estudante e a escola, seja por ser o lócus das pesquisas, seja por ser o local no qual os estudos podem impactar compreensões/transformações da realidade da escola, uma vez que inferimos que os estudos ancoram representações sociais a partir do contexto escolar. O corpus apresenta aspectos teórico-metodológicos da TRS, territórios de pertencimento e foco no professor. Porém, há fragilidades, como: ausência de articulação teórica com outras áreas do campo educacional, entre elas, as políticas educacionais e a formação do professor, pouca diversificação dos instrumentos de coleta de dados e poucas inferências que revelam ancoragens. No entanto, depreendemos os esforços dos pesquisadores em avançarem qualitativamente.

Authors: Lebimoyo A. A. , Sanni M. O.
Published: April 2024

Background: In many climes, dating violence is quite prevalent among young persons, and contemporary research has demonstrated that Nigerian youths are not exempted from this menace. Beyond the physical impact of violence, victims of dating violence could also experience common mental health problems like; depression, anxiety, and suicidality.Aims: To determine the pattern and magnitude of dating violence victimisation, and the relationship between dating violence victimisation, depression, anxiety, and suicidality among undergraduate students.Methods: This was a cross-sectional descriptive study of 118 undergraduate students recruited using convenience sampling. The questionnaires used were; the Dating Violence Questionnaire (DVQ), Suicide Behaviour Questionnaire-Revised (SBQ-R), Hospital Anxiety  and Depression Scale (HADS), and a Socio-Demographic Questionnaire.Results: Humiliation and sexual abuse were the commonest, and least common forms of dating violence victimization respectively. Humiliation was predictive of depression (P=0.04) and suicidality (P=0.04), physical abuse was predictive of anxiety (P=0.02), and sexual abuse was predictive of suicidality (P=0.03).Conclusions: There is a need for better advocacy for prevention programs against dating violence, and scaling up of mental health services for youths suffering from dating violence-related mental health problems.

Published: April 2024

Background: Psychosocial problems can significantly impact adolescents' personal and social functioning. Early identification of these problems through a brief checklist can alter the life trajectory of an individual. The Pediatric Symptom Checklist (PSC) and the Youth Self-reported Pediatric Symptom Checklist (PSC-Y) are screening tools commonly used to assess psychosocial problems among children and adolescents.Aims: This study aimed to evaluate the validity and reliability of the Sinhala versions of these tools; S-PSC and S/PSC-Y, in identifying psychosocial problems among adolescents of army war widows.Methods: The PSC and the PSC-Y, 35-item screening tools originally developed and validated in the United States were initially translated, culturally adapted using modified Delphi process and tested for judgmental validity. The PSC and PSC-Y criterion validity was appraised against clinical diagnoses by a consultant child and adolescent psychiatrist, with 156 purposively selected adolescents aged 10-19 years from the Western Province of Sri Lanka. The study used the test-retest method and internal consistency analysis to assess reliability.Results: The judgmental validity testing of both tools revealed good psychometric properties across all items. The overall Sinhala version of the PSC demonstrated a sensitivity of 87.5% (95% CI=71.0-96.5) and a specificity of 91.9% (95% CI=85.7-96.1). The overall Sinhala version of the PSC-Y demonstrated a sensitivity of 84.4% (95% CI=67.2-94.7) and a specificity of 70.2% (95% CI=61.3-78.0). Both tools showed satisfactory internal consistency with Cronbach’s alpha values of 0.88. Correlation coefficients for the Sinhala version of PSC ranged from 0.75 to 0.90, and for the Sinhala version of PSC-Y, from 0.71 to 0.79.Conclusions: The Sinhala versions of the PSC (S-PSC) and PSC-Y (S/PSC-Y) are valid and reliable tools for screening psychosocial problems among 10-19-year-olds in Sri Lanka.
IL-17RA–Mediated Epithelial Cell Activity Prevents Severe Inflammatory Response to Helicobacter pylori Infection

Published: April 2024

Helicobacter pylori is a Gram-negative pathogen that colonizes the stomach, induces inflammation, and drives pathological changes in the stomach tissue, including gastric cancer. As the principal cytokine produced by Th17 cells, IL-17 mediates protective immunity against pathogens by inducing the activation and mobilization of neutrophils. Whereas IL-17A is largely produced by lymphocytes, the IL-17 receptor is expressed in epithelial cells, fibroblasts, and hematopoietic cells. Loss of the IL-17RA in mice results in impaired antimicrobial responses to extracellular bacteria. In the context of H. pylori infection, this is compounded by extensive inflammation in Il17ra−/− mice. In this study, Foxa3creIl17rafl/fl (Il17raΔGI-Epi) and Il17rafl/fl (control) mice were used to test the hypothesis that IL-17RA signaling, specifically in epithelial cells, protects against severe inflammation after H. pylori infection. The data indicate that Il17raΔGI-Epi mice develop increased inflammation compared with controls. Despite reduced Pigr expression, levels of IgA increased in the gastric wash, suggesting significant increase in Ag-specific activation of the T follicular helper/B cell axis. Gene expression analysis of stomach tissues indicate that both acute and chronic responses are significantly increased in Il17raΔGI-Epi mice compared with controls. These data suggest that a deficiency of IL-17RA in epithelial cells is sufficient to drive chronic inflammation and hyperactivation of the Th17/T follicular helper/B cell axis but is not required for recruitment of polymorphonuclear neutrophils. Furthermore, the data suggest that fibroblasts can produce chemokines in response to IL-17 and may contribute to H. pylori–induced inflammation through this pathway.
The NLRP3 Inflammasome Is a Major Cause of Acute Renal Failure Induced by Polypeptide Antibiotics

Drug-induced acute renal failure (ARF) is a public health concern that hinders optimal drug therapy. However, pathological mechanisms of drug-induced ARF remain to be elucidated. Here, we show that a pathological process of drug-induced ARF is mediated by proinflammatory cross-talk between kidney tubular cells and macrophages. Both polymyxin B and colistin, polypeptide antibiotics, frequently cause ARF, stimulated the ERK and NF-κB pathways in kidney tubular cells, and thereby upregulated M-CSF and MCP-1, leading to infiltration of macrophages into the kidneys. Thereafter, the kidney-infiltrated macrophages were exposed to polypeptide antibiotics, which initiated activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome. Interestingly, blockade of the NLRP3 activation clearly ameliorated the pathology of ARF induced by polypeptide antibiotics, suggesting that a combination of the distinct cellular responses to polypeptide antibiotics in kidney tubular cells and macrophages plays a key role in the pathogenesis of colistin-induced ARF. Thus, our results provide a concrete example of how drugs initiate ARF, which may give insight into the underlying pathological process of drug-induced ARF.

Evaluation of DNA Damage in Oral Squamous Cell Carcinoma by Comet Assay
Authors: Halder Maheswar , Sardar Joyeeta , Mondal Parthasarathi
Published: April 2024

Background:

The Comet assay is a technique used to detect DNA damage at the single-cell level. This study aimed to investigate the potential relationship between the histopathological grading of oral squamous cell carcinoma (OSCC) and genotoxicity (DNA damage).

Methods:

Blood samples were collected from both normal subjects and patients diagnosed with OSCC. Slides prepared for the Comet assay were analyzed using an electrofluorescent microscope with a calibrated eyepiece to measure the total image length and head diameter. DNA tail length was calculated by subtracting the head diameter from the total length.

Results:

In the evaluation of DNA damage in 26 OSCC patients compared to 10 controls, a significantly higher level of DNA damage was observed in OSCC patients (P < 0.001). When considering different histological grades, the mean DNA damage was found to be highest in poorly differentiated (29.9 μm), followed by moderately differentiated (25.60 μm), and lowest in well-differentiated (23.28 μm) cases. Although differences in the average DNA damage did not reach statistical significance among the histological grades (P > 0.05), all “t” values fell below the critical values at the 5% level, indicating no significant differences between the stages.

Conclusions:

The extent of DNA damage in OSCC was highest in poorly differentiated cases, followed by moderately differentiated and well-differentiated cases. These findings suggest a potential link between histopathological grading and DNA damage in OSCC.

Effect of Shock Absorber Friction on Vehicle Vertical
Dynamics
Authors: Deubel Clemens , Schneider Scott Jarod , Prokop Günther
Published: April 2024

In order to efficiently predict and investigate a vehicle’s vertical dynamics, it
is necessary to consider the suspension component properties holistically.
Although the effects of suspension stiffness and damping characteristics on
vertical dynamics are widely understood, the impact of suspension friction in
various driving scenarios has rarely been studied in both simulation and road
tests for several decades.

The present study addresses this issue by performing driving tests using a
special device that allows a modification of the shock absorber or damper
friction, and thus the suspension friction to be modified independently of other
suspension parameters. Initially, its correct functioning is verified on a shock
absorber test rig. A calibration and application routine is established in order
to assign definite additional friction forces at high reproducibility
levels.

The device is equipped in a medium-class passenger vehicle, which is driven on
various irregular road sections as well as over single obstacles. For all tested
road sections, a linear decrease of ride comfort in terms of specific relevant
vertical objective values is found by increasing the friction force. This
emphasizes a definite link between suspension friction and vertical vehicle body
vibration, resulting in a negative impact on vertical ride comfort. However, the
longitudinal vehicle body vibration is not significantly affected.

The relevance of friction in terms of transmitting the energy associated with
road unevenness to the chassis in the frequency range of the chassis’ natural
frequency is found to be remarkably high on smooth roads, and still considerably
high on bumpy roads. The chassis and wheel resonance frequencies are
significantly friction-dependent due to the damper’s slip or stick states. The
results obtained from smooth road tests demonstrate the practical relevance of
accurately considering friction for the given suspension type in terms of
vertical ride comfort prediction.
UK merger control post Microsoft/Activision: Phase 3, behavioural remedies, and the beginning of the end of the panel?
Authors: Scanlan Ronan
Published: April 2024

This article critically examines the procedure adopted by the Competition and Markets Authority in its review of Microsoft’s anticipation acquisition of Activision, which concluded on 13 October 2023, and what it might tell us about the next decade of CMA merger enforcement.

It explores how the notion of ‘material change of circumstances’ was successfully deployed by the parties to overturn the CMA’s initial prohibition decision and how this ‘second bite of the cherry’, or ‘Phase 3’ might be utilized in future cases. It explains how, unlike the cases that came before it, Microsoft/Activision forced the CMA to overturn its Final Report and accept a negotiated settlement in place of defending the prohibition decision in the CAT, sidelining the Panel. It considers whether the case has set a precedent (however exceptional) for the CMA to accept re-notification of substantially the same merger after an initial prohibition decision, and whether fix-it-first (or ‘fix it last’) behavioural remedies may now find even more favour, including once the CMA’s Digital Markets Unit joins the show. It concludes with an examination of how the CMA’s approach in this case, coupled with its proposed reforms to the Phase 2 process, may presage the beginning of the end of the CMA’s panel system in UK merger review.
Defining relevant markets in digital ecosystems – challenges under the current framework and a path forward
Authors: Iñíguez Macarena Viertel
Published: April 2024

The legal and economic literature has recently argued that the market definition concept is no longer suitable as a theoretical framework for competition analysis concerning digital ecosystems. The issue relies on the fact that competition law aims to treat value-creation markets as the same as production markets, which are distinct. Indeed, the literature has emphasized that ecosystems’ distinctive and novel elements lie in their architecture, rules and complementarities that result from such structures. These elements make it necessary to move beyond the traditional market definition, which places emphasis on product substitution, towards a concept based on organizational structure and complementarities derived from ecosystems. This article proposes adopting a new framework for market definition, named ‘Competitive Environment for the Firm Under Investigation’, and applies it to the Google Android case. This exercise provides insightful considerations to the competition analysis of the different layers of the digital economy.
Theories of harm for digital mergers
Authors: Allan Philippa , Zele Georgia , White Alex
Published: April 2024

Merger control plays a crucial role in ensuring that digital markets work for consumers. The growing prominence of digital firms has brought about substantial benefits for society, but also novel challenges that require competition authorities to adapt their analytical approach and evidence gathering. In the UK, the Competition and Markets Authority has evolved its approach to assessing mergers in digital markets to take account of the particular features of competition in those markets, including by updating and revising its Merger Assessment Guidelines in 2021. This article discusses the CMA’s approach to reviewing digital mergers, including, by reference to a number of recent cases, how it assesses the horizontal, vertical and conglomerate effects of such mergers.
A dual character theory of law
Authors: Almeida Guilherme da Franca Couto Fernandes
Published: April 2024

One persistent question in jurisprudence relates to the role of morality in the concept of law. For instance, consider the question of whether unjust statutes are laws. Legal positivists say that they’re laws in every relevant sense, while natural lawyers say that they’re not. This article considers a different answer inspired by recent findings in experimental philosophy: there is one relevant sense in which unjust statutes are laws, but also a different relevant sense in which they aren’t. After considering the ways in which this alternative differs from some of the mainstream theories in general jurisprudence, the article argues that it provides more elegant solutions to two problems that have puzzled legal philosophers in the past: the paradox of customary international law and the shifts in legal discourse over history.
John Finnis and the central case constitution
Authors: Costa Renato
Published: April 2024

This article formulates a novel conception of constitutions based on John Finnis’s jurisprudential work. The ‘central case constitution’ transcends the formal or functionalist analyses currently dominant in constitutional theory by considering a constitution as having a ‘double life’. Constitutions are necessarily and intrinsically normative and factual. The article explores Finnis’s natural law philosophy, emphasizing the central case constitution’s alignment with the practical reasonableness viewpoint and its role in directing a political community towards its common good. Focusing on key elements such as the rule of law and the context of a political community, the central case constitution emerges as a legal determination that structures society, frames political institutions and authoritatively directs communities towards justice. This ontological understanding has theoretical and practical implications, including identifying genuine constitutional purposes, safeguarding private associations from the overwhelming state presence, promoting community identity and accommodating diverse constitutional choices for self-determination.
Samochód dla Kowalskiego. Polaków drogi do masowej motoryzacji i codzienność motoryzacyjna w okresie 1971–1989
Authors: Hubert Wilk
Published: April 2024

The text aims to provide an insight into the everyday automotive life of owners of passenger cars during the last two decades of the Polish People’s Republic. The turning point of the 1960s and 1970s in the communist bloc countries marked a shift towards consumption, with a particular emphasis on individual motorization. In Poland, the new ruling team under Edward Gierek announced a significant increase in the production of passenger cars. The licensing agreement for manufacturing the Fiat 126p at the Passenger Car Factory was intended to be a milestone in the development of individual motorization. The people enthusiastically embraced the government’s plans, and there was a mass prepayment for the ‘maluch’ (Fiat 126p). Unfortunately, throughout the two decades discussed, it was impossible to meet the popular demand for this car fully. The altered sales system in 1981 failed due to production shortages, and the waiting period extended to even ten years. As a result, Poles turned massively towards car markets. Acquiring a car and its subsequent maintenance involved specific expenses. Therefore, the possibilities of obtaining and using a car were tied to a certain income level. The sharp increase in the number of cars significantly impacted leisure activities, especially the development of automotive tourism.
Mineralogiczna kolekcja w Gabinecie Historii Naturalnej księżnej Anny z Sapiehów Jabłonowskiej
Authors: Arabas Iwona
Published: April 2024

The article concerns one of the mineralogical parts of the Cabinet of Natural History of Duchess Anna Jabłonowska (1728–1800), created in Siemiatycze. In 1802, the collection was purchased from Jabłonowska’s heirs by the envoys of Tsar Alexander I and transported to the Moscow University. At that time, two catalogues were created: one in French (1801) as a sale offer and the second one in Russian (1802), compiled by academicians during the packing of the collection before its transport to Moscow. Thanks to these two catalogues preserved in the Archives of the Russian Academy of Sciences, St. Petersburg Branch (SPbF ARAN), it is possible today to reconstruct the contents of the Cabinet, which was burned in Moscow in 1812. The mineralogical part is presented according to the contemporary classification, allowing for the determination of its scientific value. Both discovered documents complement each other and confirm the richness of the collection.
Nurses’ Attitude and Responsibilities Toward Elderly Care at a Tertiary Level Hospital in Bangladesh
Authors: Hasan Towhid Al , Mallick Dipali Rani , Mondal Reva , Anowar Mohammad Nurul
Published: April 2024

Background: Due to Bangladesh's rapidly ageing population, elderly care has become a priority issue. Nurses are key in providing quality care, but there's a knowledge gap about their attitudes and responsibilities. This study aimed to understand how nurses perceive their role in elderly care. Objective: The study assessed nurses' attitudes and responsibilities toward elderly care at a tertiary-level hospital in Bangladesh. Methods: A descriptive correlational study was conducted among senior staff nurses at Dhaka Medical College Hospital from July 2022 to June 2023. A sample size of 112 was selected using a convenience sampling technique. Data was collected using a self-administered structured questionnaire consisting of three parts: (1) Socio-demographic and Professional Characteristics Questionnaire; (2) Attitude towards Elderly Care Questionnaire; and (3) Professional Responsibility towards Elderly Care Questionnaire. The data were analyzed using descriptive and inferential statistics with SPSS software. Results: The majority of nurses (67.9%) had a positive attitude and 59.8% showed high professional responsibilities. Male nurses demonstrated higher professional responsibility than female nurses (p = .007). Nurses' attitudes and responsibilities towards elder care were influenced by their professional educational degree, marital status, working area, and working shift. A significant relationship was found between attitudes and responsibilities (r = 0.210, p = .026). Conclusion: Most nurses showed a positive attitude and high professional responsibility toward elderly care. However, a significant number of nurses had a neutral attitude and showed low to moderate professional responsibilities. This suggests a need for ongoing education and training for nurses on the importance of quality elderly care. The study also helps nursing managers to better select nurses for effective elderly care. Future studies should examine factors influencing nurses' attitudes and responsibilities, the effectiveness of education and training programs, and the perspectives of elderly patients and their families.

This manuscript explores the critical issue of sustainable agriculture and responsible land use, emphasizing the significant role of good agricultural practice (GAP). Despite land being a fundamental resource, a considerable number of farmers, including those in livestock farming, often exhibit irresponsible behavior towards its preservation. Recognizing this as a fundamental concern, the European Union has implemented stringent regulations to address the issue. The initial section of the paper outlines the identification of the problem and provides a concise overview of the European Union’s initiatives in this realm. The subsequent section delves into the contentious use of nitrates, a prevalent element in fertilizers aimed at boosting agricultural production. The authors present fundamental aspects of the code of good agricultural practice and its overarching implications, with a focus on the potential application of the code and the integration of the nitrate directive into the legislation of the Republic of Serbia. The manuscript concludes by highlighting the current environmental state in agriculture, asserting that it falls short of satisfactory levels. The authors emphasize the necessity for additional measures to align with the accepted standards of the European Union, underscoring the ongoing imperative for enhanced environmental stewardship in agricultural practices.

In this paper, the biodegradability of three SferiCorn™ biocomposites was investigated. Corn stover prepared through eco-friendly washing and grinding to short fibers was used as reinforcement. Three different biopolymers, corn starch, alginate and poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), were used as matrices. The biodegradability of prepared composites was investigated in a simulated soil burial test and the samples were characterized in terms of weight loss and morphological changes. It was shown that biodegradability can be tuned by biopolymers used as matrices. Changes in the surface morphology after biodegradation of tested samples were confirmed using scanning electron microscopy (SEM).

What often happens that weeds are not controlled after harvesting the cultivated crop. Thus, they continue to grow unhindered on agricultural land, becoming dangerous hosts for a large number of plant diseases and sources of constant infection. So far, there have been no systematic studies of the mycopopulation of weed seeds in Serbia. In this paper, we present the results of preliminary research. Weed seeds samples were collected during the summer and autumn vegetation of 2023. Isolation was performed using standard phytopathological methods. In these studies of the mycopopulation of weed seeds, a total of 500 seeds originating from ten weed species were examined. Seven genera of fungi were determined in this way: Penicillium, Fusarium, Alternaria, Cladosporium, Epicoccum, Rhizopus and Mucor.
