Eggs are nutritious food commodities that are consumed all around the world. Freshness is a major contribution to egg quality. However, eggs are perishable and susceptible to quality losses, and contaminated with certain microorganisms during storage. Currently, there are very few companies such as Ba Huan, CP, and Dabaco in Vietnam operating technology for processing poultry eggs and most of the eggs are sold untreated (no washing or disinfection). The study aims to determine the effect of saline, hot water, and Litsea cubeba essential oil (EO) on the freshness of chicken eggs including weight loss, air cell size, Haugh unit, Yolk index, pH, total viable count properties and shelf life of eggs at 370C storage. The best preservation effect was found in the sample sprayed with L. cubeba EO at 4 mg/mL, followed by dipping in hot water at 650C for 90 s and dipping in saline solution at 0.9% for 30 s to maintain the freshness of egg. The EO-treated egg could remain at average quality for up to 16 days at 370C compared to 7 days of untreated sample. The obtained results demonstrated the potential application of natural products in food preservation.

Authors: Modesto dos Santos Vitorino , Modesto dos Santos Lister Arruda
Published: July 2024

The incidence of extrapulmonary tuberculosis is growing, and it is estimated that up to 25% of all cases may be extrapulmonary infections, while the reports of genitourinary sites of this infection remain scarce, in special with the epididymis involvement. Bilateral epididymal tuberculosis is an exceeding rare cause of infertility in young, and the GeneXpert MTB/RIF test is considered a useful tool to the diagnosis confirmation. The major routes for scrotal tuberculosis are retrograde extensions from the infections in the prostate or seminal vesicles, and pelvic hematogenous or lymphatic disseminations. Aiming to emphasize the case study of isolated epididymal tuberculosis recently published in this Journal, short additional comments on literature data are presented

Historia, recepción y mundo antiguo
Authors: Alderete Matías , Jakubowicz Florencia
Published: July 2024

El presente trabajo se propone realizar un balance historiográfico del campo de estudio conocido como recepción de la Antigüedad, haciendo énfasis en la recepción de las sociedades antiguas de “Mesopotamia” y Egipto. Su desarrollo es relativamente reciente, pero cuenta con una importante proyección desde hace aproximadamente una década. Estos estudios han permitido indagar no solamente el contexto de descubrimientos arqueológicos significativos, sino también su circulación en la sociedad, la elaboración de imaginarios sobre mundos pasados y su vínculo con los valores, ansiedades y expectativas que generaron en las audiencias receptoras. De esta forma, la noción de Antigüedad cobra un valor heurístico no ya como un período histórico delimitado y determinado por especialistas, sino como un concepto que permite desentrañar fenómenos históricos y relaciones opacas o escurridizas; y también revisar las diferencias entre las investigaciones de diferentes tradiciones.
El artículo explora ciertos lineamientos generales en relación con la reflexión historiográfica, las historias disciplinares y el surgimiento de los estudios de recepción de la Antigüedad oriental, concluyendo con algunos interrogantes y proyecciones.

Sorption technology using anion exchange resin is used in the processing of gold-bearing ores of the Muruntau deposit. Studies have shown that despite the high selectivity for gold, silver and other associated non-ferrous metals, which are valuable from the point of view of the integrated use of mineral raw materials, are sorbed to some extent by ion-exchange resin. Studies have shown that it is possible in principle to extract silver from acidic waste solutions by precipitation using various precipitating reagents. This article presents the results of semi-industrial tests of the scheme for obtaining silver from waste solutions of ion exchange resin regeneration. The final product was a silver ingot with a metal content of 87,7%. In the future, anodes can be cast from the resulting silver ingot and 99,99% silver can be obtained by electrochemical method.

Published: July 2024

В статье изложены сведения о разработке технологии приготовления «пастовой закладки» – закладки высокой плотности с явно выраженными тиксотропными свойствами. Такая закладка впервые была разработана и внедрена научными сотрудниками Казахского политехнического института и работниками комбината «Ачполиметалл». «Пастовая закладка» на основе хвостов флотации с высоким содержанием оксида кальция позволила получить закладочные смеси с соотношением T:Ж = 80:20 с подвижностью 12-14 см, которая сохранилась в течение всего времени транспортирования. После укладки смесь быстро загустевала практически без усадки. Проектная прочность искусственного массива 1,5…2 МПа достигалась в короткие сроки при расходе цемента в 1,5…2 разы ниже, чем на других рудниках.

The article presents information about the development of technology for the preparation of «paste backfill» – backfill of high density with pronounced thixotropic properties. Such a backfill was first developed and implemented by the researchers of the Kazakh Polytechnic Institute and the workers of the Achpolimetal plant. «Paste backfill» based on flotation tailings with a high content of calcium oxide made it possible to obtain backfill mixtures with a ratio of S:L = 80:20 with a mobility of 12-14 cm, which was preserved throughout the entire transportation time. After laying the mixture quickly thickened with little or no shrinkage. The design strength of the artificial massif 1.5...2 MPa was achieved in a short time at a cement consumption 1.5...2 times lower than in other mines.
Corrosion Behavior of Cu-Ni-Fe-Mn-Cr Alloy in 3.5 wt% NaCl Solution
Authors: Li Shifang , Xiao Zhu , Fang Mei , Xie Haofeng , Peng Lijun
Published: July 2024

A novel Cu-10Ni-1.7Fe-0.5Mn-0.2Cr alloy was fabricated and exposed to a neutral 3.5 wt% NaCl solution for various days. The corrosion performance, corrosion film, and corrosion mode of the alloy were investigated in detail. The results suggested that the average corrosion rate reduced from 0.082 mm/a for 1-d immersion sample to 0.037 mm/a for 30-d immersion sample. The reduction in corrosion rate was mainly attributed to the progressive thickness and densification of the corrosion film, leading to increasing the resistance of the corrosion film with the prolonged exposure time. Low-valent oxides and chlorinated compounds were generated over the 1-d immersion sample surface, while high-valent oxides and hydroxide compounds were developed over the 30-d immersion sample surface. The mature corrosion film typically composed of Cu2O, CuO, Cu2(OH)3Cl, γ-FeOOH, MnO2, and Cr2O3. Eventually, the alloys suffered from selective corrosion and intergranular corrosion after a long exposure time in NaCl solution.
Corrosion Behavior of Supermartensitic Stainless Steel 13Cr and Stainless Steel 316L Under Chloride Solution and H2S/CO2 Environments
Authors: Soares Costa Josiane , Altenhofen Aldo
Published: July 2024

Corrosion-resistant alloys (CRAs) include various stainless steels and nickel alloys used in corrosion-aggressive environments encountered in oil and gas operations. Supermartensitic stainless steel (SMSS 13Cr) has been used in the manufacture of steel tubes for oil drilling due to a more financially viable option to replace the austenitic stainless steel (SS 316L) in the oil and gas market. This present work estimates the effect of the hydrogen sulfide (H2S) on SMSS 13Cr and SS 316L in a saline solution, simulating the operating conditions in the oil and gas industry. Corrosion behavior was monitored using a potentiodynamic-potentiostatic-potentiodynamic technique to obtain pitting potential (Ep) or crevice potential (Ecrev) and repassivation potential (Erp) while the long-term open-circuit potential technique was applied to estimate the stable corrosion potential (Ecorr*). A scanning electron microscope equipped with energy dispersive x-ray spectroscopy and optical microscopy was used for surface characterization. With all analyses performed, it was possible to propose a trend regarding the pitting probability. The pitting increases with increasing H2S concentration on SSSM 13Cr; consequently, larger and deeper pits were observed, making it possible to develop into cracks if there are mechanical stresses. On the contrary, the pitting probability for the SS 316L is low (compared with SMSS 13Cr) for all environments reproduced here in this research.

Los proyectos de arancelamiento universitario en Argentina y la oposición del movimiento estudiantil (1989-1995)
Authors: Cristal Yann
Published: July 2024

Este trabajo investiga los proyectos de arancelamiento universitario sostenidos por el gobierno de Carlos Menem durante su primer mandato y la temprana oposición que recibieron tales planteos por parte del movimiento estudiantil en Argentina. A partir de una variada serie de fuentes y de referencias, el artículo recorre la cuestión de la gratuidad universitaria durante el siglo XX para luego concentrarse en las características de la agenda menemista hacia la educación superior, en la que el posible arancelamiento aparecía como un elemento central, y en el crecimiento de una corriente de opinión mayoritaria en las facultades en contra de esa posible medida, desde los primeros momentos del gobierno de Menem. En este sentido, el trabajo sostiene que la gratuidad universitaria, uno de los rasgos que distinguen a la universidad argentina actual en el contexto regional, estuvo seriamente amenazada durante los noventa y que su continuidad no puede explicarse sin considerar la resistencia que opusieron el movimiento estudiantil y otros actores durante esos años.

Published: July 2024

The process of digitalization, technology and information is an important momentum and opportunity for humanity to take advantage of all forms of contemporary developments in the digital world, including its use as a learning medium. Video media is an alternative used in learning activities and one of them is YouTube. However, not all teachers accept changes in circumstances and technology to be used as evaluation material in order to improve themselves better. Not a few teachers persist in past teaching patterns because they think that their teaching experience has shown success in the students they teach. Such understandings are reluctant to make changes, because they are considered to threaten patterns that have existed for a long time. In fact, technological developments have influenced every line of life and required new adaptations from humans in interacting with each other, including in the educational process. This problem does not occur with PAI teachers at SDN Semen. Existing PAI teachers have been able to adapt to increasingly advanced and developing technology. Even PAI teachers at the school are accustomed to using online features in learning activities. What's more interesting is that PAI teachers are able to use YouTube media even though they are still faced with several inadequate supporting facilities and also limited internet wifi in some classes. Based on this phenomenon, the aim of this research is to describe more fully the implementation of YouTube as a learning medium and will describe how PAI teachers implement this media-based learning. This research uses qualitative research with a descriptive approach, collecting data through non-participant observation, unstructured interviews and documentation. The research results show that YouTube implementation goes through three stages, namely planning, implementation and evaluation.

THE IMPACT OF AI ON INTERNAL AUDITING: TRANSFORMING PRACTICES AND ENSURING COMPLIANCE
Authors: Beatrice Oyinkansola Adelakun
Published: July 2024

Artificial Intelligence (AI) is revolutionizing internal auditing by transforming traditional practices and enhancing compliance mechanisms. This abstract explores the multifaceted impact of AI on internal auditing, highlighting key advancements in efficiency, accuracy, risk management, and regulatory adherence. AI technologies, particularly machine learning and advanced data analytics, are enhancing the capabilities of internal auditors to analyze large volumes of data swiftly and with greater precision. Traditional internal auditing methods, often constrained by manual processes and sampling techniques, are being supplanted by AI-driven approaches that offer comprehensive analysis and real-time insights. This shift enables auditors to identify anomalies, fraud, and operational inefficiencies more effectively, thereby improving the overall accuracy and reliability of audit outcomes. One of the significant benefits of AI in internal auditing is its ability to automate routine and repetitive tasks. By leveraging AI, auditors can focus on higher-value activities, such as strategic risk assessment and decision-making, thus enhancing the overall productivity of the audit function. Furthermore, AI-driven tools can continuously monitor financial transactions and operational processes, providing real-time alerts and insights that help in early detection of potential issues and proactive risk management. AI also plays a crucial role in ensuring compliance with regulatory standards. By integrating AI systems with compliance frameworks, organizations can automate the tracking and reporting of compliance-related activities. This not only reduces the risk of human error but also ensures that organizations stay updated with evolving regulatory requirements. AI’s ability to process and analyze regulatory texts enables organizations to swiftly adapt to new compliance mandates, thereby mitigating the risk of non-compliance penalties. However, the integration of AI into internal auditing is not without challenges. Ensuring data quality and integrity is paramount, as AI systems rely on accurate data inputs to function effectively. Additionally, the "black box" nature of some AI algorithms can pose transparency issues, making it difficult for auditors to explain how specific conclusions were reached. Addressing algorithmic biases and maintaining auditor expertise in AI technologies are also critical considerations. In conclusion, AI is significantly transforming internal auditing practices by enhancing efficiency, accuracy, and compliance. While the benefits are substantial, careful management of data quality, transparency, and algorithmic biases is essential to fully realize the potential of AI in internal auditing.

Published: July 2024

The aim of this study was to explore how the use of mathematics laboratories affects the development of mathematics skills in learners from selected public secondary schools in Musanze District, Rwanda. Adopting constructivism theory, the study utilized a descriptive research design and a mixed-methods approach to collect both quantitative and qualitative data from surveys, interviews, and classroom observations, respectively. The study randomly sampled 348 learners and 16 mathematics teachers from the targeted population of 2679 participants. In relation to students' standardized test scores and teacher assessments, the analysis examined the frequency of lab use, lab activities, resource quality, and teacher training. Findings from quantitative data revealed positive correlations between lab usage and skill development across all measures. The frequency of lab use and teacher training were particularly strong predictors of improved performance. The results show that how often teachers use the lab (B =.122, p <.001) and their training and support (B =.150, p =.010) have a big effect on their evaluations, which means that these things have a positive effect on evaluations. In contrast, the types of lab activities and the quality of lab resources have no significant impact. These findings suggest that enhancing lab use frequency and providing robust training and support for teachers are crucial for improving teacher assessments. Interview results show that hands-on activities significantly boost critical thinking and the real-world application of mathematical concepts. From classroom observations, the study revealed remarkable discrepancies in student participation and resource availability between day and boarding schools. The findings suggest that the school administration should incorporate lab activities into the curriculum, enhance the frequency of lab use, and facilitate continuous teacher training by providing sufficient resources. Teachers should integrate engaging lab activities to strengthen theoretical concepts and encourage active learning. Students are urged to actively participate in lab sessions and look for help when necessary. These results help us understand how mathematics laboratories can improve learning outcomes in Rwandan secondary schools.

A obesidade é uma condição crônica e complexa que requer abordagens terapêuticas multifacetadas. Sendo assim, a tirzepatida, um medicamento de ação dupla que combina efeitos agonistas dos receptores GIP e GLP-1, tem demonstrado benefício significativo na redução de peso e melhora dos parâmetros metabólicos em pacientes obesos. Esse trabalho tem por objetivo analisar a eficácia da terapia com tirzepatida no controle da obesidade. Foi realizada uma Revisão Integrativa da Literatura, com busca no PUBMED e na BVS, utilizando os Descritores em Ciências da Saúde em inglês "Obesity", "Tirzepatide", "efficacy" e "Adults”, combinados pelo operador booleano AND. Os resultados destacaram que o análogo de GIP e GLP-1 é superior em relação aos outros incretinomiméticos, alcançando uma taxa de redução de peso superior a 5%, com melhora na saúde cardiometabólica do paciente, reduzindo os riscos cardiovasculares e ateroscleróticos pré-existentes. No entanto, possui algumas contraindicações, sendo elas: seu uso em gestantes, pacientes com neoplasias endocrinometabólicas ou histórico familiar dessas condições, além de reações adversas gastrointestinais, risco de pancreatite, doenças hepáticas e risco de abstinência. Conclui-se que embora seus efeitos, a terapêutica é benéfica para ser implementada no tratamento da obesidade.

Esse artigo busca apresentar os resultados de uma pesquisa que discutir o contexto, a efetividade e os resultados da intervenção do Projeto Pedagógico da Escola de Aplicação Ministro Reis Velloso, da cidade de Parnaíba (PI), voltado para a alfabetização e letramento de crianças, do segundo ao quinto ano do ensino fundamental, afetadas pelas perdas educacionais decorrentes da Pandemia do COVID-19. A problemática envolve as questões referentes às situações de aprendizagem que estão relacionados ao déficit na alfabetização e letramento dos alunos e das alunas, em decorrência da ineficiência do ensino remoto emergencial. A pesquisa realizada foi de cunho qualitativo, buscando uma aproximação com o método etnográfico, cuja produção dos dados foi realizada com um grupo formado por uma docente e dois bolsistas do Curso de Pedagogia, da Universidade Federal do Delta do Parnaíba, envolvidos no referido projeto. A conclusão é que o projeto teve como resultado a constatação de que o ensino remoto emergencial, de fato, não proporcionou a consolidação da alfabetização de todos os alunos e alunas da escola, embora tenha cumprido seus objetivos, gerando impactos positivos nas atividades e na formação dos futuros educadores/ras.

Abstract. The methodology to determine the unfiltered solar and thermal radiances from the measured EarthCARE Broadband Radiometer (BBR) shortwave (SW) and total-wave (TW) filtered radiances is presented. Within the EarthCARE ground processing, the correction for the effect of the BBR spectral responses, the unfiltering, is performed by the so-called BM-RAD processor which produces the level-2 BM-RAD product. The BM-RAD product refers to unfiltered broadband radiances that are derived from the BBR and the Multi-Spectral Imager (MSI) instruments on board the forthcoming EarthCARE satellite. The method is based on theoretical regressions between filtered and unfiltered radiances, as is done for the Clouds and the Earth's Radiant Energy System (CERES) and the Geostationary Earth Radiation Budget (GERB) instruments. The regressions are derived from a large geophysical database of spectral radiance curves simulated using radiative transfer models. Based on the radiative transfer computations, the unfiltering error, i.e., the error introduced by the small spectral variations of the BBR instrument response, is expected to remain well below 0.5 % in the shortwave (SW) and 0.1 % in the longwave (LW), at 1 standard deviation. These excellent performances are permitted by the very simple optics used in the BBR instrument: a telescope with a single paraboloid mirror. End-to-end verification of the unfiltering algorithm has been performed by running the BM-RAD processor on modelled level-1 BBR radiances obtained for three EarthCARE orbits simulated by an integrated forecasting and data assimilation system. The resulting unfiltered radiances are eventually compared to the solar and thermal radiances derived by radiative transfer simulations over the three EarthCARE orbits. In addition, this end-to-end verification has provided further evidence on the high accuracy of the unfiltered radiance process, with accuracies better than 0.5 % for SW and better than 0.1 % for LW.

Abstract. Nitrous oxide (N2O) is a potent greenhouse gas and ozone depletion agent, with a significant natural source from marine oxygen-deficient zones (ODZs). Open questions remain, however, about the microbial processes responsible for this N2O production, especially hybrid N2O production when ammonia-oxidizing archaea are present. Using 15N-labeled tracer incubations, we measured the rates of N2O production from ammonium (NH4+), nitrite (NO2-), and nitrate (NO3-) in the eastern tropical North Pacific ODZ and the isotopic labeling of the central (α) and terminal (β) nitrogen (N) atoms of the N2O molecule. We observed production of both doubly and singly labeled N2O from each tracer, with the highest rates of labeled N2O production at the same depths as the near-surface N2O concentration maximum. At most stations and depths, the production of 45N2Oα and 45N2Oβ were statistically indistinguishable, but at a few depths there were significant differences in the labeling of the two nitrogen atoms in the N2O molecule. Implementing the rates of labeled N2O production in a time-dependent numerical model, we found that N2O production from NO3- dominated at most stations and depths, with rates as high as 1600 ± 200 pM N2O d−1. Hybrid N2O production, one of the mechanisms by which ammonia-oxidizing archaea produce N2O, had rates as high as 230 ± 80 pM N2O d−1 that peaked in both the near-surface and deep N2O concentration maxima. Based on the equal production of 45N2Oα and 45N2Oβ in the majority of our experiments, we infer that hybrid N2O production likely has a consistent site preference, despite drawing from two distinct substrate pools. We also found that the rates and yields of hybrid N2O production were enhanced at low dissolved oxygen concentrations ([O2]), with hybrid N2O yields as high as 20 % at depths where [O2] was below detection (880 nM) but nitrification was still active. Finally, we identified a few incubations with [O2] up to 20 µM where N2O production from NO3- was still active. A relatively high O2 tolerance for N2O production via denitrification has implications for the feedbacks between marine deoxygenation and greenhouse gas cycling.
