Exposure to glyphosate-based herbicides (GBH) and consumption of cafeteria (CAF) diet, which are widespread in Western society, seem to be associated with endometrial hyperplasia (EH). Here, we aimed to evaluate the effects of a subchronic low dose of GBH added to the CAF diet on the rat uterus. Female Wistar rats were fed from postnatal day (PND)21 until PND240 with chow (control) or CAF diet. Since PND140, rats also received GBH (2 mg of glyphosate/kg/day) or water through food, yielding four experimental groups: control, CAF, GBH, and CAF+GBH. On PND240, CAF and CAF+GBH animals showed an increased adiposity index. With respect to the control group, no changes in the serum levels of 17β-estradiol and progesterone were found. However, progesterone levels were higher in the CAF+GBH group than in the CAF and GBH groups. In the uterus, both studied factors alone and in combination induced morphological and molecular changes associated with EH. Furthermore, the addition of GBH provoked an increased thickness of subepithelial stroma in rats fed with the CAF diet. As a consequence of GBH exposure, CAF+GBH rats exhibited an increased density of abnormal gland area, considered preneoplastic lesions, as well as a reduced PTEN and p27 expression, both tumor suppressor molecules that inhibit cell proliferation, with respect to control rats. These results indicate that the addition of GBH exacerbates the CAF effects on uterine lesions and that the PTEN/p27 signaling pathway seems to be involved. Further studies focusing on the interaction between unhealthy diets and environmental chemicals should be encouraged to better understand uterine pathologies.

In brief

Preantral follicles constitute the largest follicle reserve in the mammalian ovary. This study assesses a mechanical isolation method to maximize the number of follicles retrieved from a defined cortex volume.

Primordial, primary, and secondary follicles (collectively defined as preantral follicles) constitute the most abundant source of gametes inside the mammalian ovarian cortex. The massive isolation of preantral follicles and the refinement of stage-specific protocols for in vitro follicle growth would provide a powerful tool to boost the rescue and restoration of fertility in assisted reproduction interventions in human medicine, animal breeding, and vulnerable species preservation. Nevertheless, together with an efficient culture system, the most significant limitation to implementing in vitro follicle growth is the lack of an efficient method to isolate viable and homogeneous subpopulations of primordial, primary, and secondary follicles suitable for in vitro culture. Our study provides a strategy for high-yielding mechanical isolation of primordial, primary, and early secondary follicles from a limited portion of the ovarian cortex in the bovine animal model. In the first part of the study, we refined a mechanical isolation protocol of preantral follicles, adopting specific methodological strategies to separate viable and distinct subpopulations of primordial (oblate and prolate forms), primary, and early secondary follicles from 0.16 cm3 of the ovarian cortex. In the second part of the study, we tested the effectiveness of the isolation protocol, considering the individual’s age as a critical factor, bearing in mind the progressive decrease in the ovarian reserve that naturally accompanies the reproductive life span. Our study provides a way for designing quantitative and conservative fertility preservation approaches to preserve organ function and minimize the invasiveness of the interventions, also considering age-related differences.

In this work, we study the existence and uniqueness of a common best proximity point for a pair of nonself functions that are not necessarily continuous using the simulation function. In the following, we state important common best proximity point theorems as results of the main theorems of this article. This achievement allows us to have an example that covers our main theorem but does not apply to the Banach contraction principle. Finally, an application of a nonlinear fractional differential equation to support the obtained conclusions.
Shaping the Future: Insights from a Longitudinal Study on Women’s Career Aspirations during Pregnancy and Postpartum
Authors: Ražauskienė Vilma
Published: April 2024

This longitudinal study delves into the meanings of work for women during a transitional life stage. While the topics of opting out and opting in have garnered considerable attention, certain aspects of career development after childbirth remain underexplored. Existing literature often dichotomizes women into two primary groups, and some theories propose a three-group classification. However, such divisions may be overly simplistic and not universally applicable to all women. The objective of this study is to enhance the understanding of women’s career aspirations. In order to achieve this objective, two waves of individual semi-structured interviews with ten women at two specific time points were conducted: during pregnancy and four to six months postpartum. The results of the study demonstrate that the meaning of work for the research participants varied both during pregnancy and after childbirth. Additionally, some participants had alteredtheir career aspirations after they became mothers. The salience of the new identity as a mother is discussed as a possible precursor explaining adjustments in the career aspirations. This research enriches the discourse on work–life balance preferences by offering valuable insights into how early motherhood shapes women’s career goals, decisions, and expectations.

Scientific review of the latest author’s works on tectonics and geodynamics of the territory of Ukraine, as well as its connection with the localization of mineral deposits, is presented. The structure and evolution of lithosphere of the Carpathian and Black Sea segments of Ukraine, the Dnieper-Donetsk Basin, Donbass Foldbelt and Ukrainian Shield has been reconstructed based on the interpretation of regional deep sounding (DSS) and reflection (CDP) seismic profiles, the geomagnetic field data, geological-structural mapping, paleotectonic, numerical modeling, paleogeographical and palinspastic reconstructions. When interpreting the DSS profiles, the classic velocity models are supplemented with seismic images obtained by the original finite-difference reflection/refraction migration method. The monograph included scientific study carried out at the S.I. Subbotin Institute of Geophysics of the National Academy of Sciences of Ukraine with the involvement of seismic and related geophysical data obtained as a result of conducting and interpreting regional wide-angle seismic profiles (WARR): DOBRE’99, PANCAKE and RomUkrSeis. Geological interpretation of reflection seismic profiles of the Ukrainian sector of the Black Sea, paleogeographical and palinspastic reconstructions contributed to the study of the evolution of the entire Black Sea region. The geological evolution of the Ukrainian Carpathians is reconstructed on the basis of updated data on stratigraphy, tectonics, lithology and sedimentology and palinspastic reconstructions. The structure and development of the DDB sedimentary cover was revealed by seismogeological sections along numerous reflection (CDP) seismic profiles. The tectonics of the Precambrian Ukrainian Shield, including the Kryvyi Rih-Kremenchug and Golovanivsk suture zones, were studed by geomagnetic field analysis and detailed geological and structural mapping.

A multidisciplinary committee developed evidence-based guidelines for the management of cystic fibrosis transmembrane conductance regulator-related metabolic syndrome/cystic fibrosis screen-positive, inconclusive diagnosis (CRMS/CFSPID). A total of 24 patient, intervention, comparison, and outcome questions were generated based on surveys sent to people with CRMS/CFSPID and clinicians caring for these individuals, previous recommendations, and expert committee input. Four a priori working groups (genetic testing, monitoring, treatment, and psychosocial/communication issues) were used to provide structure to the committee. A systematic review of the evidence was conducted, and found numerous case series and cohort studies, but no randomized clinical trials. A total of 30 recommendations were graded using the US Preventive Services Task Force methodology. Recommendations that received ≥80% consensus among the entire committee were approved. The resulting recommendations were of moderate to low certainty for the majority of the statements because of the low quality of the evidence. Highlights of the recommendations include thorough evaluation with genetic sequencing, deletion/duplication analysis if <2 disease-causing variants were noted in newborn screening; repeat sweat testing until at least age 8 but limiting further laboratory testing, including microbiology, radiology, and pulmonary function testing; minimal use of medications, which when suggested, should lead to shared decision-making with families; and providing communication with emphasis on social determinants of health and shared decision-making to minimize barriers which may affect processing and understanding of this complex designation. Future research will be needed regarding medication use, antibiotic therapy, and the use of chest imaging for monitoring the development of lung disease.

Published: April 2024

We report on the case of a 16-year-old boy with myocarditis developing after the third dose of COVID-19 mRNA vaccine. The patient presented with fever and retrosternal chest pain two days after immunisation. On admission, the boy was in good condition, with stable vitals. Elevated serum troponins and electrocardiographic repolarisation abnormalities with normal echocardiographic contractility were noted. Cardiac magnetic resonance imaging revealed active myocarditis in form of oedema with late gadolinium enhancement in five segments of the left ventricle myocardium. During further hospitalisation, rapid improvement in the patient’s general condition with normalisation of troponin level, and regression of electrocardiographic abnormalities were observed. In follow-up reassessments at three and nine months, cardiac magnetic resonance revealed residual myocardial lesions. No symptoms and abnormalities in laboratory tests, electrocardiography, or echocardiography were found. It is imperative to exercise full vigilance for COVID-19 vaccine-associated myocarditis when chest pain appears following vaccination, even in the absence of alarming symptoms after previous vaccine doses.

Authors:   Nelson Mandela University, South Africa., Jonas Altouise G.
Published: April 2024

In a post COVID-19 era the tourism industry has been forced to adapt to a changing business world evident in the paradigmatic shifts in tourist behavior. The industry has been forced to transform in order to recover from the devastation caused by the pandemic. A strategy which could prove useful for the rejuvenation and the sustainability of the tourism industry is the provision of memorable experiences. Understanding the dimensions that contribute to memorable experiences is vital for the success of tourism businesses. Therefore, the aim of the study was to investigate which dimensions contribute to a memorable marine tourism experience (MMTE) in South Africa. The exploratory research design and mixed method approach were applied in the study. A total of 444 usable questionnaires were analyzed by means of descriptive and inferential statistics. The results indicate that eight dimensions positively relate to MMTEs. Hedonism is the most important dimension to increase the likelihood of shark-diving experiences being remembered. Whereas, five dimensions in particular (refreshment, social-interaction, meaningfulness, knowledge and novelty) will increase the memorability of whale-watching experiences, while an increase in delight will enhance the memorability of the experience for all three activities (whale-watching, shark-diving and visits to marine protected areas (MPAs). The results of the study are important for marine tourism businesses who want to stage memorable experiences, in order to meet the needs of their customers and to enhance the relevance and sustainability of their businesses.

Machine Learning Based Predictive Modelling of Vehicle CO2 Emissions: An Extensive Examination of Automobile Features
Authors: Shetty Jahnavi , V Haripriya
Published: April 2024

There is a growing interest in discovering novel and inventive methods to decrease the emission of carbon dioxide (CO2) from diverse sources, mostly due to concerns about safeguarding the environment and mitigating the adverse effects of greenhouse gas emissions, especially in the automotive sector. This study article explores the fascinating potential of predicting the quantity of CO2 generated by autos using machine learning (ML) based methodologies. In order to create a system that can predict carbon dioxide emissions depending on a number of factors, we are investigating machine learning. Significant details about the car, such as its construction, kind, number of cylindrical objects, horsepower, gearbox type, fuel type, and fuel consumption, are included in the dataset that forms the basis of our investigation. This project's main objective is to create accurate and dependable prediction models for calculating vehicle-generated CO2 emissions. Legislators that deal with the environment, corporations, and consumers could find great value in these models. We use a range of machine learning (ML) techniques, such as ensemble techniques, neural networks, decision trees, and regression algorithms, to accomplish this goal. This study assesses the prediction accuracy, adaptability to different situations, and data utilisation of several techniques. To determine which predictive models are most suited for predicting CO2 emissions within the limitations of the given information, we employ a comprehensive evaluation process. Additionally, we look at how different feature subsets affect prediction accuracy, providing an indication of the relative significance of different vehicle parameters in relation to CO2 emissions. Our results advance the field of predictive emissions models and provide insight on the primary drivers of vehicle-related greenhouse gas emissions.
Network Traffic Virtualization Using Wireshark and Pygeoip
Authors: N Ansar Dheen , V Haripriya
Published: April 2024

Security analysts possess the requisite expertise to discern various types of network traffic, detect instances of unusually high activity, and pinpoint the specific network nodes responsible. Furthermore, network traffic visualization aids users in pinpointing servers and tracking data flows, thereby enabling researchers to identify potential online threats. Leveraging Wireshark's functionalities as both a packet tracer and capture tool, the process of network analysis hinges on the selection of appropriate packet capture parameters. In this study, Wireshark serves as the cornerstone for creating a network tracking system. By employing Wireshark to capture data packets, analyze them, and subsequently translate the IP addresses into latitude and longitude coordinates, researchers can plot the source and destination IPs on a Google map. This innovative approach allows users to visualize network traffic patterns on a geographical scale and effectively monitor them.

Invasive poeciliids dominate fish community in a highly altered river: insights from a diversity study of riverbank fishes in Mexico
Authors: Córdova-Tapia Fernando , Palomera-Hernández Vianey , Camacho-Cervantes Morelia
Published: April 2024

Abstract The presence of invasive species can cause significant changes in native communities and ecosystem functions. Mexico is home to 6% of all known freshwater fish species on the planet, with a high rate of endemism. Due to heavy urbanization, the Mexican Central Plateau has become one of the most densely populated areas in the world, and its Tula River is considered one of the most polluted rivers in Mexico. Our objective was to investigate whether native fish species persist in such adverse conditions and to evaluate the seasonal and spatial distribution of both native and non-native species at three sites along the Tula River. We evaluated environmental characteristics and fish community structure. We found two native species, the black fin goodea (Goodea atripinnis) and the yellow shiner (Notropis calientis). However, their abundance was extremely low across all sites and seasons. In contrast, invasive poecilids dominated the communities, accounting for 99.4% of the total abundance. Our results indicate a clear relationship between river characteristics and fish community structure, highlighting the significance of river width, river velocity, temperature, dissolved oxygen, and pH. The prevalence of invasive species underscores the urgent need for conservation efforts aimed to protect and restore native fish populations.

Authors: Halfeld João Carlos , Caldana Jaqueline
Published: April 2024

Resumen La sedación paliativa integra el amplio conjunto de prácticas y acciones de los cuidados paliativos. Su objetivo principal no es acelerar el final de la vida, sino proporcionar confort y alivio de los síntomas de los pacientes terminales. Esta práctica genera opiniones divergentes tanto en el ámbito académico y profesional como en el social y religioso. Esta revisión integradora de la literatura busca levantar las discusiones e investigaciones más pertinentes en el escenario brasileño para contribuir a la construcción de una noción más actualizada y adecuada contemporáneamente sobre sedación paliativa. El surgimiento, la opinión de médicos y estudiantes, los factores bioéticos y los desafíos en la aplicación constituyen temas de discusión sobre la sedación paliativa en el final de la vida. Sin embargo, la literatura disponible sobre este tema sigue siendo escasa, permeada de cuestiones sociales, éticas, religiosas y profesionales que requieren interpretaciones individuales y consenso entre las esferas sociales.
The Decline of Exegesis: on the teaching performance of Gilles Deleuze
Authors: Vinci Christian Fernando Ribeiro Guimarães
Published: April 2024

ABSTRACT Based on some discussions on the teaching performance of Gilles Deleuze, present in some recent francophone literature, this essay will seek to present some correlations between this Deleuzian teaching performativity and elements of the author’s philosophy. To this end, we will present a brief overview of the discussion found in a series of commentators, correlating them with conceptual discussions present in the Deleuzian and Deleuzian-Guattarian corpus. As a guiding hypothesis, we argue that Deleuze has a concern to philosophize from a sensitive rather than rational perspective, being impossible to understand his teaching practice without taking into consideration his appeal for a philosophical sensitivity.

Published: April 2024

RESUMO O artigo analisa se há associação da desigualdade na infraestrutura das escolas municipais de educação infantil (EMEIs) de Belo Horizonte quanto i) à localização, ii) ao tipo de gestão e iii) à correção de informação censitária prestada, em relação ao ano de 2019. Os dados do Censo Escolar foram cotejados com indicadores econômicos e visitas in loco. Verificou-se que a distribuição territorial das EMEIs e o tipo de administração têm repercussões no grau de adequação de infraestrutura das escolas. Porém, essas variáveis apresentaram pouco poder explicativo para as desigualdades encontradas no Censo Escolar daquele ano. Em contrapartida, identificou-se discrepâncias entre os dados preenchidos pelas unidades educacionais e as informações verificadas em visitas locais.

Entre “tradições” e “modernidades”: agrupamentos carnavalescos de Luanda na primeira metade do século XX
Authors: Marzano Andrea
Published: April 2024

RESUMO Este artigo é resultado de uma investigação, baseada em fontes jornalísticas, sobre os desfiles dos agrupamentos carnavalescos de Luanda na primeira metade do século XX. De um lado, são analisadas as representações dos jornalistas sobre os cortejos. De outro, são discutidas as maneiras pelas quais seus componentes escolheram se apresentar. Articulando esses dois objetivos, pretende-se discutir a problemática dos hibridismos culturais, demonstrando, sob inspiração de Néstor Canclini, Serge Gruzinski e Homi Bhabha, a insuficiência de oposições binárias, como colonizador e colonizado, moderno e tradicional, para a compreensão da sociedade colonial. Problematizando a simplificação de universos sociais heterogêneos em cada um dos referidos polos, e considerando a centralidade do racismo como elemento definidor de possibilidades, pretende-se demonstrar que as categorias jurídicas de indígena, europeu e assimilado não permitem uma compreensão adequada das múltiplas experiências dos indivíduos e grupos presentes na cidade.

Published: April 2024

Resumo O objetivo do artigo é identificar os indutores de conectividade existentes entre os conselhos estaduais e nacionais de Direitos Humanos. Os governos eleitos no Estado e na União imprimiram um conjunto de mudanças no funcionamento dos conselhos, sobretudo, naqueles ligados à área de Direitos Humanos. Portanto, é importante analisar as mudanças e possíveis consequências das mesmas para as políticas públicas. Não há estudos comparativos da mesma natureza na literatura, sendo essa a principal contribuição do artigo. A metodologia ancora-se em técnicas da Análise de Redes Sociais para configurar as redes estaduais e nacionais. O problema da pesquisa é o seguinte: Quais são os possíveis indutores de conexão entre os conselhos estaduais e nacionais de Direitos Humanos? A hipótese é a de que a sociedade civil pode ser um importante conector, quando se considera o problema da coordenação federativa, isto é, a relação entre os conselhos estaduais e nacionais. Resultados preliminares indicam mudanças muito expressivas na composição e dinâmica de funcionamento dos conselhos. Importa caracterizar melhor as possíveis consequências para as respectivas áreas.

Published: April 2024

Resumo O artigo discute a relação entre o médico Antônio Fernandes Figueira e a higiene infantil no período de institucionalização dos estudos acerca da saúde da criança no Brasil. A higiene infantil é fruto da emergência do conceito de saúde em contraposição à doença. Interessa-nos compreender como a higiene infantil se estabeleceu, se em parceria ou oposição à pediatria. Enfatizamos como a circulação das ideias sobre a saúde da criança chegou ao país e como esse médico dialoga com as discussões europeias e as reinterpreta. Nosso fio condutor é a alimentação infantil como pilar da higiene infantil. Para tal, nos baseamos no Livro das mães: consultas práticas de higiene infantil, publicado pelo médico em 1910.

Resumo Este artigo busca compreender a vocação científica consagrada pela primeira geração (1973-1977) de pesquisadores do Programa de Pós-graduação em Sociologia do Instituto Universitário de Pesquisas do Rio de Janeiro (Iuperj). Embora o Iuperj seja visto como berço da moderna ciência política brasileira, pouco se sabe sobre sua sociologia. Para tal, baseamo-nos em documentos, entrevistas e bibliografia secundária. Queremos nuançar diagnósticos sobre essa geração, ora vista como excessivamente heterogênea, ora como pouco original se comparada à ciência política iuperjiana. Na vocação daquela geração, o elogio à especialização teórico-metodológica era parte central de uma sociologia política que buscava dar respostas às demandas de uma sociedade na encruzilhada entre modernização e redemocratização.
DIGCN: A Dynamic Interaction Graph Convolutional Network Based on Learnable Proposals for Object Detection
Authors: Cao Pingping , Zhu Yanping , Jin Yuhao , Ruan Benkun , Niu Qiang
Published: April 2024

We propose a Dynamic Interaction Graph Convolutional Network (DIGCN), an image object detection method based on learnable proposals and GCN. Existing object detection methods usually work on dense candidates, resulting in redundant and near-duplicate results. Meanwhile, non-maximum suppression post-processing operations are required to eliminate negative effects, which increases the computational complexity. Although the existing sparse detector avoids cumbersome post-processing operations, it ignores the potential relationship between objects and proposals, which hinders detection accuracy improvement. Therefore, we propose a dynamic interaction GCN module in the DIGCN, which performs dynamic interaction and relational modeling on the proposal boxes and proposal features to improve the object detection accuracy. In addition, we introduce a learnable proposal method with a sparse set of learned object proposals to eliminate a huge number of hand-designed object candidates, avoiding complicated tasks such as object candidate design and many-to-one label assignment, and reducing object detection model complexity to a certain extent. DIGCN demonstrates accuracy and run-time performance on par with the well-established and highly optimized detector baselines on the challenging COCO dataset, e.g. with the ResNet-101FPN as the backbone our method attains the accuracy of 46.5 AP while processing 13 frames per second. Our work provides a new method for object detection research.
Load transfer mechanisms for capped and uncapped non-displacement piles above tunnels: a centrifuge modelling study
Authors: Tang Chuanjin , Franza Andrea , Xu Jingmin , Marshall Alec M.
Published: April 2024

This paper presents results from geotechnical centrifuge tests of tunnelling in dry dense sand beneath loaded non-displacement piles, focusing on the effect of a pile cap (representative also of a raft or grade beam) in contact with the soil surface on load transfer mechanisms. Experiments included loading tests to ascertain the foundation capacity and load–displacement response in the presence/absence of an underlying model tunnel. Individual ‘reference’ pile response is compared for cases with and without a pile cap, including pile displacements and load distributions between the head, shaft and base; the case of ‘friction’ piles with a compressible base is also considered. Results show that uncapped piles with relatively large service loads experience ‘geotechnical failure’ (i.e. large settlements or a significant increase in settlement rate with tunnel volume loss) in order to mobilise base or shaft resistance. Pile caps are shown to reduce settlements and prevent geotechnical failure of both reference and friction piles; they also improve the post-tunnelling foundation performance under loading. The paper provides evidence to enable engineers to consider the beneficial role of shallow elements in contact with the surface on the performance of pile foundations both during and subsequent to tunnelling.
James Joyce, Oscar Wilde, and Punitive Child Loss in the Modern Bureaucratic State
Authors: Backus Margot Gayle
Published: April 2024

The intense ambivalence of James Joyce’s references to Oscar Wilde throughout Joyce’s literary career poses a riddle to which scholars have proposed an array of answers. This article seeks the basis for Joyce’s simultaneous identification and disidentification with Wilde in the strata of painful affect that informs collective subjectivity in the modern nation-state. In late 19th century Britain, two nebulous new crimes, coined at the urging of the Social Purity movement—gross indecency, and custodial neglect—rendered families and communities newly vulnerable to punitive child loss. The enforcement of these new laws created conditions under which one might lose custody of one’s children based on a charge that could be brought by anyone, based on anything, or nothing. Gross indecency and child neglect were both ill-defined and highly stigmatizing. Both were difficult to defend against, while their most terrible consequences were often extra-judicial. In De Profundis, Oscar Wilde conveys the dehumanizing anguish of extra-judicial punishments that could be indiscriminately imposed on a new kind of moral criminal by depicting the loss of his children as a figurative crucifixion. This article charts accounts by social historians describing the National Society for the Prevention of Cruelty to Children’s early years in Dublin, and the organization’s impact on socially precarious families, alongside episodes from Joyce’s biography, and his literary reinventions of these episodes. Using passages from De Profundis that influenced Joyce’s writing, historical accounts of moral policing introduced by the Social Purity movement, and Joyce’s biographical materials, letters, and published writing, this article connects changing affect in Joyce’s childhood family to the intense aversion, outrage and empathy that color his recurrent allusions to what he termed Oscar Wilde’s ‘civil death.’
Christoph Schlingensief im Spannungsfeld von Kunst und Realpolitik
Authors: Vinzenz Alexandra
Published: April 2024

Christoph Schlingensief gründete 1998 die Partei Chance 2000. Es handelt sich dabei sowohl um eine künstlerische Arbeit als auch ein realpolitisches Handeln. Diese Entgrenzung von Kunst und Politik ist ein Bestreben im Konzept des Gesamtkunstwerks, welches um 1850 von Richard Wagner entwickelt wurde und unter anderem von Joseph Beuys aufgegriffen und modifiziert wurde; beide Künstler führt Schlingensief als Leitfiguren an. Die Betrachtung des Konzepts Gesamtkunstwerks hilft bei der Analyse der künstlerischen und sozio-kulturellen Bestrebungen der Künstler sowie der Frage nach der Interaktion mit der Gesellschaft. Auf diese Weise können verschiedene Schwerpunktlegungen, Mechanismen und Strategien offengelegt werden. Der kunsthistorische und theaterwissenschaftliche Blick, der methodische Ansätze der Postcolonial Studies mit einbezieht, trägt zur Verortung von Schlingensiefs Arbeiten bei.
Investigation of old waste dump composition of lean gold-bearing ores from the Golden Pride Project (GPP) mining operation in Nzega district, Tanzania

The search for alternative sources of useful minerals is a pressing issue. One such possible source is the processing of lean gold-bearing ores, which previously did not seem feasible to exploit for subsoil users, leading to their disposal in off-balance ore dumps. Processing these resources becomes economically viable as gold prices rise and processing technologies improve over time. This paper presents the elemental and mineralogical composition of lean gold-bearing ore dumps from the Golden Pride Project (GPP) mining operation in Tanzania’s Lihendo district. This area contains an old dump of lean gold-bearing ores, weighing approximately 1.4 million tons. Extracting valuable components from lean mineral raw materials is a current priority. Sampling was conducted to study the dumps. Boreholes were drilled to a depth of 1 m, covering a total sampling area of 20 ha; 18 samples, each averaging 3 kg in weight, were collected. The results of X-ray fluorescence analysis (XRF) indicated the presence of Fe, S, Si, Ca, Ca, Mn, Cu, Al, Cr, Ti, As, and Ag in the collected samples. X-ray diffraction (XRD) analysis revealed that the main minerals in the dumps are muscovite, kaolinite, quartz, montimorillonite, and goethite. The average gold grade in the selected samples is 0.72 g/t. Studies of the grain-size distribution and gold distribution by grain-size classes after ore grinding demonstrated that the majority of gold (74%) is in the −75 μm class. In the initial mineral material of the dumps, the share of the +30-50 mm grain-size class is 81%. The paper proposes potential methods for processing lean dumps of gold-bearing ores. One such methods involves crushing the dump material, separating the −75 μm class, and subjecting it to direct leaching or leaching using “carbon-in-pulp” technique. Heap leaching appears to be the most promising method for extracting gold from such dumps in terms of technical and economic feasibility. Positive experience has been reported in applying this process to ores of similar mineralogical type.
Characterization and thermal behavior of some types of kaolin of different origin from Northern Vietnam

Kaolin (mainly composed of kaolinite, whose chemical formula is Al2Si2O5(OH)4), serves as a versatile raw material widely used in various industries including production of ceramics, paper, paints, cosmetics, pneumatics, building materials, and hazardous waste storage. In the northern part of Vietnam, due to favorable geological conditions, there are diverse deposits of high quality kaolin of different origin and scale. Decades of research indicate the diversity of kaolin sources in the region, with special attention paid to hydrothermally altered and exchange types of kaolin, the formation of which is associated with complex processes of weathering, hydrothermal alteration and reprecipitation. The aim of this study was to characterize three different types of kaolin derived from different sources in Northern Vietnam (from weathered pegmatites, weathered felsic effusives, and hydrothermal-metasomatic altered rocks). The main focus was to analyze the thermal behavior of these samples during calcination in the temperature range from 300 °C to 1,100 °C. The comprehensive characterization was performed by X-ray diffraction (XRD), FT-IR spectroscopy (FT-IR), thermal analysis (thermogravimetry / differential thermogravimetry (TG / DTG)) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS). The results showed that kaolinite with particle size less than 2 μm was identified in all samples. Minor amounts of muscovite and montmorillonite are present in some samples, and pyrophyllite is present in a sample from the hydrothermally altered rocks. Kaolinite morphology in all the samples showed typical forms including hexagonal and pseudohexagonal. The main chemical constituents of the samples are SiO2 and Al2O3; in addition to these, K2O + Na2O, TiO2 and iron are present in smaller quantities. Thermal analysis allowed to reveal the formation of metakaolinite phase at temperatures around 494 °C and 507 °C in the two studied samples from weathered rocks, while the pyrophyllite-bearing sample undergoes this transition at a higher temperature of 653.8 °C. The onset of metakaolinization was observed at about 500 °C for the weathered rock samples and about 700 °C for the pyrophyllite-bearing sample. In addition, mullitization leading to the formation of mullite was evident at 1,100 °C. The study findings allow concluding that the studied kaolins can be used in traditional ceramics production.
