Published: December 2024

Two experiments assessed the effects of providing a vitamin and mineral supplement to gestating beef heifers on concentrations of immunoglobulins (Ig) in colostrum and calf serum 24 h after feeding maternal colostrum (Exp. 1) or a colostrum-replacement product (Exp. 2). Angus-based heifers (n = 31, Exp. 1; n = 14, Exp. 2) were fed a basal diet (CON) or were fed a basal diet plus a vitamin and mineral supplement (VTM) from breeding (Exp. 1) or 60 d pre-breeding (Exp. 2) through calving. Colostrum was collected at calving, and serum was collected from calves 24 h after colostrum consumption to evaluate passive transfer. Serum was collected from calves in Exp. 1 to determine serum titers in response to vaccination at birth, pasture turn out, weaning, and 14 d after vaccination. Concentrations of IgG, IgM, or IgA in colostrum or in calf serum at 24 h were not impacted by dam treatment (p ≥ 0.21); however, concentrations of Ig in calf serum at 24 h were greater (p ≤ 0.01) in calves receiving maternal colostrum than those receiving a colostrum replacer. Calves born to VTM heifers had greater antibody titers at birth, pasture turn out, and weaning for infectious bovine rhinotracheitis (IBR), bovine viral diarrhea virus type 2 (BVD-2), and bovine respiratory syncytial virus (BRSV), respectively. Our results suggest that the programming of immune function in calves via prenatal nutrition appears to extend postnatally in CON and VTM offspring.

Published: December 2024

Poultry represents a rich source of multiple nutrients. Refrigeration is commonly employed for poultry preservation, although extended storage duration can adversely affect the meat quality. Current research on this topic has focused on the analysis of biochemical indices in chilled goose meat, with limited information on changes in metabolites that influence the quality of the meat during storage. This study used non-targeted metabolomics and the random forest algorithm to investigate metabolite changes in goose meat over an extended storage period. The results showed a significant change in the composition of the meat as the duration of storage increased, with the identification of 121 distinct metabolites. Further analysis identified 18 metabolites that could be used as indicators of the degradation of carbohydrates, amino acids, nucleotides, and lipids. These metabolites could be used as markers to monitor the deterioration process. These intermediate metabolites tended to be transformed into lower-level products involving pyruvate, acetyl coenzyme A, and fumaric acid, used in the tricarboxylic acid cycle, performing substance transformation. This comprehensive analysis of metabolites provides a valuable reference for monitoring the freshness of goose meat, potentially improving the safety of domestic poultry products.

Authors: Williams Simone A. , Megdal Sharon B. , Zuniga-Teran Adriana A. , Quanrud David M. , Christopherson Gary
Published: December 2024

Groundwater is a vital drinking water source, especially in arid regions, sustaining both urban and rural populations. Its quality is influenced by natural (hydrogeological) and human-driven (demographic, policy) factors, which may pose significant public health risks, especially for communities relying on unregulated water supplies. This study addresses critical gaps by examining groundwater vulnerability and contamination disparities, emphasizing their implications for public health and equitable resource management. It analyzes the impact of socio-hydrogeological factors on arsenic and nitrate levels in groundwater-supplied systems in Arizona, U.S. Methods include spatial analysis, ANOVA, multivariate regression, and cluster analysis. Significant disparities in arsenic and nitrate contamination, including exceedances of regulatory limits, were observed across supply types, aquifer characteristics, jurisdictional oversights, and groundwater management areas. Domestic wells and community water systems showed distinct contamination risks. Groundwater vulnerability was influenced by geological differences (karst vs. alluvial aquifers) and regulatory oversight, with Tribal and State systems facing unique challenges and resource needs. Socioeconomic disparities were evident, with minority communities, institutional facilities, rural areas, and specific housing types disproportionately exposed to higher contaminant levels. These findings unveil the intersection of race, socioeconomic status, and public health risks, offering an adaptable framework for addressing similar groundwater challenges in arid and semi-arid regions globally. This study is innovative in its focus on policy distinctions between private and regulated wells, karst and alluvial aquifers, and State and Tribal jurisdictions. It emphasizes the need for targeted vulnerability assessments and remediation strategies that integrate geological, hydrological, and regulatory factors to address risk disparities in vulnerable communities. These environmental inequities underscore the urgent need for stronger regulations and strategic resource allocation to support marginalized communities. The study recommends enhancing monitoring protocols, prioritizing resource distribution, and implementing targeted policy interventions to ensure equitable and sustainable access to safe drinking water in arid regions.

Published: December 2024

By 2030, the global deficit in freshwater resources is projected to reach 40%, in direct correlation with global population growth. To cope with this increase in demand, the Sustainable Development Goals outlined by the United Nations, specifically goal No. 6 of the 2030 agenda, have identified wastewater as a new resource. Indeed, the reuse of wastewater offers three primary advantages: (i) Reused wastewater can serve as an alternative to water from natural reserves, particularly in sensitive geographical areas experiencing water stress. (ii) Wastewater reuse limits the discharge of treated water into the natural environment, which is often a source of pollution, thus helping preserve ecosystems. (iii) Wastewater reuse also facilitates the extraction of valuable compounds, such as fertilisers and precious metals, along with energy generation. This review focuses on various uses of water and the global reuse of treated wastewater from wastewater treatment plants (WWTPs). The focus then shifts to pesticides, exploring the origins of these emerging contaminants and their impacts on aquatic environments. An in-depth analysis of diuron follows, examining its origin, toxicity and regulation and the performance of existing advanced treatments to produce safe water from WWTP effluents.

Large plastic items in the environment are degraded into tiny pieces known as microplastics (MPs). MP contamination in tropical lagoon ecosystems poses a significant pollution threat. The mud crab, Scylla serrata, is an important crustacean in the tropical lagoon, valued as a key source of edible seafood in Asia and Europe. The potential MPs of one hundred samples were examined using the stereomicroscope for characterisation, and further analysis was conducted using µ-FTIR. A total of 1157 MPs were found in the gills and gastrointestinal tract. The mean abundance (±SD) of MP in mud crabs was 11.57 ± 6.29 items/individual. MPs were detected in both tissues, displaying a variety of colours. Transparent MPs dominated the gills at 43.9%, while blue microplastics were prevalent in the gastrointestinal tract at 32.8%. The filament (fibre) was the most prominent MP type found in the gills and gastrointestinal tract. The collected MPs from both tissues were categorised into four size ranges: 0.05–0.25 mm and 1.00–5.00 mm were the common size ranges in the gills and gastrointestinal tract, respectively. The prominent polymer type was rayon. These findings provide considerable proof of MP contamination in the mud crab species Scylla serrata and its implications for food security.

Published: December 2024

Water pollution caused by fluoranthene (FLN), phenanthrene (PHE), and pyrene (PYR) has become an increasingly serious issue in recent years. Consequently, finding effective methods to remove these pollutants from aquatic environments is of paramount importance. This study investigated the removal rate of FLN, PHE, and PYR from simulated wastewater using persulfate (PS) and explored the effects of PS catalyzed by three different forms of schwertmannite (sch): sch-1, sch-2, and sch@BC (schwertmannite-biochar composite), and the BET of sch-1, sch-2, sch@BC has been detected, which were 1.09 cm3/g, 11.30 cm3/g, and 6.10 cm3/g. The results showed varying removal rates after a 1 h reaction time for different treatments: For FLN: sch-1+PS (98.5%), sch-2+PS (54.2%), sch@BC+PS (21.1%), and PS alone (14.8%). For PHE: sch-1+PS (94.3%), sch-2+PS (44.1%), sch@BC+PS (28.4%), and PS alone (7.6%). For PYR: sch-1+PS (97.2%), sch-2+PS (52.5%), sch@BC+PS (14.2%), and PS alone (1.7%). Among the catalysts tested, sch-2 (added 0.36 mL H2O2 five times) demonstrated excellent catalytic ability in enhancing the PS removal of FLN, PHE, and PYR. This research provides theoretical support for treating polycyclic aromatic hydrocarbon (PAH)-containing wastewater via persulfate oxidation catalyzed by schwertmannite.
Assessing Operational Efficiency of Bubble Plumes for Water Circulation Enhancement
Authors: Choi Seongeun , Kim Dong Hyeon
Published: December 2024

Bubble plumes are essential for promoting mass transfer, flow, and mixing in water bodies by generating vertical circulation via buoyancy forces. They are widely used in various applications, such as restoring water environments and improving the conditions at the bottom of lakes and reservoirs. For example, thermal stratification in lakes can lead to environmental issues such as the depletion of dissolved oxygen. To address this problem, bubble plume systems have been used to destratify lakes and reservoirs. However, few studies have been performed on the effectiveness of bubble plumes. In this study, the impact of a bubble plume in a dam reservoir was assessed using a numerical model based on high-resolution field measurements. Vertical profiles were obtained before and after the operation of the density-current generator to capture seasonal changes in the water characteristics. These measurements indicated the alteration of the vertical structure and mixing within the water column due to the bubble plume while stable temperatures were maintained at specific depths across seasons. Numerical simulations using large eddy simulations were conducted to analyze the dynamics and mixing efficiency of the bubble plume. The findings of this study provide valuable data for optimizing the design and operational strategies of bubble plume systems in lakes and reservoirs, which can increase the water mixing efficiency and support environmental management.

Authors: Körmen Ahmet , Arslan Arda , Yaran Zümra , Kaya Gülsüm , Altındiş Mustafa
Published: December 2024

Aim: Human papilloma virus (HPV) is the most common viral infection agent of the reproductive system. A large portion of sexually active women and men are infected with this virus at some point in their lives. The aim of this study was to examine the knowledge, attitudes and behaviors of university students about HPV vaccines.
Materials and Methods: The research survey was applied to volunteer university students as an online Google survey. The survey form consists of a total of 23 questions aimed at evaluating demographic information and knowledge about HPV vaccines. The results were transferred to spreadsheets and evaluated using Microsoft Excel and SPSS Version 25.0 statistical package programs.
Results: A total of 300 students participated in the study. According to the descriptive statistics results, 71% of the participants were female, 92% were studying in the health field (medicine, dentistry, first and emergency aid, physiotherapy, nursing, etc.) and 8% were studying in departments other than health. While 7% of the students stated that they had received the HPV vaccine, 36% stated that they wanted to receive the HPV vaccine; 45% were undecided about getting vaccinated. While 63% of the students thought that HPV vaccines should be included in the routine vaccination schedule; 33% were hesitant. When asked the question “If you recommend the HPV vaccine, to whom would you recommend it?”, 17 of the students responded “To women and men with a family history of cervical cancer”, 208 of the students responded “to both men and women”, 43 of them responded “to all women”, and 10 of them responded only “to women with a family history of cervical cancer”; 22 of the students reported that they did not recommend the HPV vaccine. When the reasons for not recommending the HPV vaccine were examined, 10 of the students stated that they did not recommend the HPV vaccine due to doubts about the safety of the vaccine, 10 of them stated that they were afraid of possible negative outcomes, and 2 of them stated that they did not recommend the HPV vaccine due to difficulties in receiving adequate counseling.
Conclusion: Our study found that university students have low knowledge about HPV vaccine and infection and the vaccination rate is also low (7%). Multidisciplinary public health studies should be conducted to provide the necessary education and counseling to ensure that university students are informed about HPV vaccine.

Some New Techniques of Computing Correlation Coefficient between q-Rung Orthopair Fuzzy Sets and their Applications in Multi-Criteria Decision-Making
Authors: Ejegwa Paul Augustine , Sarkar Arun , Onyeke Idoko Charles
Published: December 2024

The term q-rung orthopair fuzzy set is an essential variant of fuzzy set with the capacity of tackling fuzziness and imprecision in the decision-making process. A fundamental concept in the decision-making process is the idea of correlation coefficient because of its wide applications. The process of decision-making is complex due to imprecisions, and as such the idea of correlation coefficient has been investigated under q-rung orthopair fuzzy setting. Some authors have constructed some techniques of correlation coefficient under q-rung orthopair fuzzy sets with practical applications. However, these existing techniques are defectives with several drawbacks in terms of precision and alignment with the conditions of correlation coefficient. In this work, two new techniques for estimating correlation coefficient under q-rung orthopair fuzzy sets are presented and theoretically discussed. Moreover, we apply the new techniques of correlation coefficient under q-rung orthopair fuzzy sets in disease diagnosis and employment process by using simulated q-rung orthopair fuzzy data based on multi-criteria decision-making approach and recognition principle. Some comparative analyses are provided to ascertain the benefits of the new techniques of correlation coefficient under q-rung orthopair fuzzy sets over the obtainable techniques with regard to reliability and performance rating.

Authors: Nugroho Ibnu Aldi , Fauziah  , Hayati Nur
Published: December 2024

Graph coloring is used, because the results of graph coloring can be used in several systems, such as the scheduling and the coloring of map areas in this study. The goal in implementing graph coloring here is to get as few colors as possible in the 44 borders of villages in Jakarta Pusat. The problem of coloring graphs on the Jakarta Pusat’s villages map uses a greedy algorithm that exists on web-based maps and makes encyclopedias to support descriptions of areas that have been colored. The greedy algorithm is a form of algorithm that is currently developing in optimization problems by forming a step-by-step solution. Greedy algorithm can be applied to resolve the problem of graph coloring. The best solution to answer a graph coloring problem is to determine the chromatic number 𝜒(𝐺) using the greedy algorithm. Graph coloring on a map is done using a greedy algorithm to obtain the minimum number of colors possible without adjacent regions using the same color. Based on the research results, the least number of colors used in coloring the village map in Central Jakarta, which consists of 44 areas, is 6 types of colors.

The conditions that make this opaque form of self-conformation of the obligation are clarified, considering the algorithmic management work model and in light of the European discipline and of a reflection on the calculative and predictive power of the artificial intelligence, which this model uses.
Riccardo Del Punta: un illuminista radicale
Authors: Barbera Marzia
Published: December 2024

The essay starts from some of Riccardo Del Punta's writings to show how , in its author's view, he was a "radical Enlightenment thinker,” torn between passion and doubt. The passion that nourished all of Del Punta's work was his humanistic passion for a classically radical liberalism, one that places at its center values that embody modern citizenship and egalitarianism: individual freedom, secularism, democratic politics, freedoms of thought and the press. These values are continuously crossed by doubt, which is cultivated as a choice of method, in an anti-ideological function. But they are also to be unyieldingly defended when under attack, as good ideals in themselves, not bound to a particular era (modernity) or cultural identity (the Western one). In that lies the “inflexible meekness” of our unforgettable friend and colleague.
Qualità del processo produttivo nell’industria della carne: le debolezze della filiera, le ricadute sul lavoro
Authors: Campanella Piera
Published: December 2024

The paper aims at analyzing the critical aspects of the meat supply chain, focusing on its weakest links, in particular, on the deplorable effects of the cost reduction policies imposed in the chain itself by the big retailers. As far as work organisation is concerned, the outsourcing phenomenon has ended up in the dock as a technique par excellence for cutting costs. The paper will dwell on the contractual forms of this phenomenon – “soccida” (agistment) in livestock farming, “contracting out” in meat processing - to verify its effects in terms of the growth of unsafe and poor quality work. Finally, the paper takes a critical look at the latest legislative interventions in the field of contracting and subcontracting, thus questioning the prospects for labour regulation in the meat sector

Sull’abuso del diritto. Riflessioni a margine della recente giurisprudenza sul rapporto di lavoro
Authors: Colosimo Chiara
Published: December 2024

Moving from Del Punta’s observations and the most recent labour jurisprudence, the author reflects on the abuse of rights as an autonomous juridical category, reconstructing its troubled doctrinal and jurisprudential background. She considers that a legal system cannot be complete without a general principle of prohibition of abuse and suggests searching for abuse within the objective perimeter of application of a given right, investigating the consistency between the way the right is exercised and the ratio of the legal recognition: a functional approach that allows abuse to be identified in the diversion from the “causal factor” of the right exercised. In this perspective, abuse is a serious contradiction: it determines the subjugation of the right to purposes unrelated to law and values.

Published: December 2024

How is employment law taught at university? While, as the years go by, the teaching of employment law focuses on the technical aspect of the subject, imbued with practical considerations, employment law must be taught in its context during the early stages: it forms part of a wider whole, that of ‘social issues’, and interacts with political science, economics and history, in particular. In any case, the professor is not there to pass on ready-made solutions, but to awaken the students' minds, methodically. This is the most valuable viatic he can offer them before they embark on their professional lives, whether or not they are dedicated to employment law.

The essay is inspired by the preface that Riccardo del Punta wrote a few years ago for Paolo Tomassetti's book and, in light of the arguments made by Riccardo on that occasion, focuses on the increasingly current problems relating to the relationship between labour law and the environment on which Riccardo Del Punta himself had carried out interesting and prophetic reflections in an essay years ago, demonstrating in particular a certain disappointment at the lack of attention paid by labour law to environmental issues.
La controversa questione della qualificazione giuridica del lavoro mediante piattaforma digitale e il fondamentale ruolo interpretativo della giurisprudenza
Authors: Spinelli Carla

The evolution of the Italian case law on the misclassification of platform workers is analysed in this article. The study highlights the fundamental role played by the jurisprudence in order to enhance working conditions and strengthen labour protections for platform workers. In this respect, the Italian experience, which is described in its fundamental stages, appears emblematic on the international scene and even pioneering with reference to the protection of collective interests. The recent approval of the EU Directive on Platform work, which introduces a rebuttable legal presumption of employment, does not seem sufficient in itself to downsize filing lawsuits for misclassification. As a consequence, the Courts rulings will still maintain full relevance for the protection of platform workers’ rights.

The study investigated teachers’ perceptions of the availability and use of cartoons as instructional materials for teaching preschool learners in Ijebu-Ode, Ogun State. A descriptive research design was employed. The population comprised preschool teachers in public primary schools in the Ijebu-Ode local government area. Simple random sampling techniques with a total of 147 preschool teachers were selected as the sample size. Three research questions and three hypotheses guided the study. A self-developed and validated questionnaire “Teacher Perception on the Use of Cartoons Questionnaire” (TPUCQ) was used for data collection with 0.84 as the reliability coefficient. Descriptive statistics were used for analyzing research questions. Hypotheses were tested using a t-test. The findings revealed that Super Why, Word World, team unizoomi, Number Blocks, Wonder Pets, and Cyber Chase were educational cartoons available and utilized for instruction delivery. Teachers perceived cartoons as instructional materials that made preschool pupils laugh or smile, open their horizons, speak volumes, increase attention, and make the lessons interesting among others. It also arouses children’s imagination. There was a significant difference in the mean ratings of teachers on the availability, use, and perceptions of cartoons as instructional materials for teaching preschool learners. Government and stakeholders within the educational industry should provide relevant educational cartoons for preschools in the Ijebu-Ode local government area of Ogun State.

Objetivo: Identificar as contribuições do Banco de Leite Humano (BLH) para a manutenção do aleitamento materno em recém-nascidos pré-termo (RNPT), a partir da perspectiva das mães. Métodos: Trata-se de um estudo descritivo, com abordagem qualitativa, fundamentado na análise de conteúdo de Bardin. A pesquisa foi conduzida em uma maternidade pública localizada em um município de Pernambuco, credenciada como Iniciativa Hospital Amigo da Criança (IHAC). Essa maternidade, referência na região, possui um BLH próprio denominado BIAMA. Participaram do estudo nove mães de RNPT internados que utilizaram os serviços do BLH e concordaram em assinar o Termo de Consentimento Livre e Esclarecido (TCLE). A pesquisa foi aprovada pelo Comitê de Ética em Pesquisa sob o Parecer n.º 033283/2021 e CAAE 45353321.5.0000.5201. Resultados: A partir da análise das falas das participantes, emergiram três categorias principais: orientações sobre o leite humano e manejo da lactação; utilização do leite pasteurizado de doadoras; e apoio social. Essas categorias são detalhadas ao longo do artigo. Conclusões: A manutenção do aleitamento materno em RNPT constitui um desafio significativo tanto para as mães quanto para os profissionais de saúde envolvidos no cuidado. O BLH desempenha um papel essencial ao oferecer orientações, conduzir o manejo de massagem e ordenha mamária para estímulo à produção láctea e suprir a demanda dos RNPT internados. Além disso, o processamento e a doação de leite humano são elementos fundamentais no apoio e incentivo ao aleitamento materno.

Hipertensi adalah kondisi yang ditandai dengan peningkatan tekanan pada pembuluh darah sistolik dan diastolik. Hipertensi menghambat proses penyediaan oksigen dan nutrisi melalui darah, yang kemudian disalurkan ke jaringan tubuh yang membutuhkannya. Penanganan sakit kepala pada subjek hipertensi dapat dilakukan dengan teknik relaksasi Benson, yang terbukti dapat mengurangi rasa sakit dan menurunkan tekanan darah. Penelitian ini bertujuan untuk mengetahui efektivitas teknik relaksasi Benson dalam mengurangi sakit kepala pada subjek hipertensi. Penelitian ini menggunakan desain studi kasus dengan memberikan intervensi berbasis bukti keperawatan berupa teknik relaksasi Benson selama 5-10 menit kepada lima subjek hipertensi yang berusia 45-65 tahun dan mengalami sakit kepala ringan hingga sedang, yang diukur menggunakan Numeric Rating Scale (NRS) 0-10. Pengukuran intensitas sakit kepala dilakukan sebelum dan sesudah intervensi, dengan evaluasi lanjutan dilakukan 30 menit setelah intervensi. Penerapan teknik relaksasi Benson terbukti efektif dalam mengurangi intensitas sakit kepala pada subjek hipertensi. Teknik relaksasi Benson dapat menjadi pendekatan non-farmakologis yang bermanfaat untuk membantu mengurangi sakit kepala pada subjek hipertensi dan mendukung proses pemulihan mereka.
