A method of dearsenizing firing in an inert atmosphere with the production of arsenic sulfides having the third hazard class in sublimations is proposed. The mineral, elemental and phase composition of raw materials are presented and analyzed. The results of the DTA are analyzed, according to which the temperature range optimal for conducting research is selected. A thermodynamic analysis of the possibility of obtaining various forms of arsenic sulfide at different operating parameters has been carried out. To carry out dearsenizing firing, a screw tube furnace is proposed as a pyrometallurgical equipment that allows to control the drying and firing temperatures of the material within a wide range, to divert the ignition into condensers, to ensure constant mixing of raw materials without its caking and sintering.

Pero es en la existente en el cimborrio central, la llamada torre de Jesucristo, en la que se centra este trabajo. Esta torre se encuentra en fase de construcción y está previsto que en su parte superior culmine con una cruz de cuatro brazos, de una altura total de 25 metros, alcanzando los 170 m su punto superior. Un elemento de considerables dimensiones y excesivo peso para que pueda ser construido según el proyecto inicial, de acero, para poder izarlo y disponerlo, con los medios mecánicos que existen hoy en día en el mercado. En consecuencia, el presente artículo tiene la finalidad de proponer y diseñar un elemento que cumpla con las prestaciones que se le requieran, sin olvidar, dada su singularidad y simbología, la componente estética del mismo.
Chimerical Procession
Authors: Tal Guy
Published: October 2023

The chapter explores monstrosity, heresy, and inversion as the prime trajectories of the subverted world of witchcraft through an analysis of Lo stregozzo, the celebrated engraving of a phantasmic parade presided over by an infanticidal naked crone, produced by Marcantonio Raimondi or Agostino Veneziano in the mid-1520s. The study centers on the visual complex formed by the arresting hybrid monster surmounted by a crouching man. While the inclusion of these two figures defies an iconographical explanation, framing the engraving in the artistic processes of imitation and invention recasts them as a means of thinking about witchcraft and art. Thus, the chimera incites reflection on visual eclecticism, while the crouching man is a sophisticated emulation of Michelangelo’s Sistine God.

Published: October 2023

It was aimed to determine the unethical behaviors of teachers and administrators from each other's perspectives in this research. The case study method, which is one of the qualitative research methods, was applied in the research. The research group of the study consisted of 20 educators, including 10 teachers and 10 administrators, working in public schools during the 2021-2022 academic year. The research data were collected through semi-structured interviews and analyzed using inductive content analysis by the researchers. According to the most important results of the research, unethical behaviors from the administrators’ perspective were determined that teachers entered and left the classes whenever they wanted, ignored professional development, avoided applying different methods and techniques in the lessons, treated students unfairly, saw grades as a punishment tool, and became negative role models for the students. On the other hand, distributing resources to people who are in personal relation to them, making tailor-made lesson plans, acting according to the teachers' unions, being careless to the children of poor families, and being negative role models for the students were among the unethical behaviors of administrators from teachers' perspective. As a result of the research, suggestions were developed to change the unethical behaviors of teachers and administrators.

Authors: Zulu Nokwanda , Majola Sindile , Krishna Suresh
Published: October 2023

Homoeopathy is a system of medicine based on the law of similars “let like be cured by like”. This means that any substance with the capacity of producing disease in its crude state has the capacity to treat a similar disease if taken in a very small dose. Homeopathic Nosodes are homoeopathic remedies sourced from diseased materials and organisms. Homoeopathic nosodes may be used to treat and prevent infectious and non-infectious diseases. The incidence of infectious diseases epidemics is now occurring more often around the world. The common public threat includes the emergence of antibiotic resistance which is increasing globally. Contributing factors of this emergence are linked to underlying biological, and environmental issues, lifestyle changes, misuse, and overprescribing of antibiotics. Despite strengthening health infrastructure, every epidemic and multi-drug resistance bacterium poses a challenge to the government, policymakers, health professionals, and the whole population. This article will review data available on homoeopathic nosodes, as well as present evidence that is available to support the use of homoeopathic nosodes in disease prevention and treatment. It also highlights several clinical trials and in vitro studies on the use of homoeopathy to target health issues that have the potential to harm public health and possibly assist in reducing healthcare costs.

Authors: ABBAS Ansar , KHALİQ Abdul
Published: October 2023

An analysis of discrete-time predator-prey systems is presented in this paper by determining the minimum amount of prey consumed before predators reproduce, as well as by analyzing the system's stability and bifurcation. In order to investigate the local stability of the interior equilibrium point of the proposed model, discrete dynamics system theory is employed first. Moreover, the characteristic equation is analyzed to determine the Neimark-Sacker bifurcation of the system. The normal form and bifurcation theory are used to investigate the NS bifurcation around the interior equilibrium point. Based on its analysis, the system exhibits Neimark-Sacker bifurcation when positive parameters are present and non-negative conditions are met. Develop a feedback control strategy to discover the region of stability of the chaotic behavior. By utilizing the maximum laypanuou exponent, the effect of initial conditions on developed systems is further explored. Finally, a computer simulation illustrates the results of the analysis.

Published: October 2023

Abstract. Net primary production of the oceans contributes approximately half of the total global net primary production, and long-term observational records are required to assess any climate-driven changes. The Ocean Colour Climate Change Initiative (OC-CCI) has proven to be robust whilst also being one of the longest records of ocean colour. However, to date, only one primary production algorithm has been applied to this data product, with other algorithms typically applied to single-sensor missions. The data product presented here addresses this issue by applying five algorithms to the OC-CCI data product, which allows the user to interrogate the range of distributions across multiple models and to identify consensus or outliers for their specific region of interest. Outputs are compared to single-sensor data missions, highlighting good overall global agreement, with some small regional discrepancies. Inter-model assessments address the source of these discrepancies, highlighting the choice of the mixed-layer data product as a vital component for accurate primary production estimates. The datasets are published in the Zenodo repository at https://doi.org/10.5281/zenodo.7849935, https://doi.org/10.5281/zenodo.7858590, https://doi.org/10.5281/zenodo.7860491 and https://doi.org/10.5281/zenodo.7861158 (Ryan-Keogh et al., 2023a, b, c, d).
Public Health Responses to Homelessness During COVID-19 in Ireland: Implications for Health Reform
Authors: Parker Sarah , Siersbaek Rikke , Mac Conghail Luisne , Burke Sara
Published: October 2023

The intersection between health and homelessness is well documented and has been made more explicit since the onset of the coronavirus disease of 2019 (COVID-19). In the Global North, COVID-19 related public health responses targeting homeless populations have varied across countries, including greater national-level financial investment, temporarily housing those in congregate facilities in ‘self-contained’ accommodation, time-limited eviction moratoriums and dedicated health system interventions across homelessness and addiction services to enable social distancing and self-isolation. Yet questions remain about the immediate and longer-term outcomes of these newly implemented responses and whether they will be sustained. Such considerations are critical and timely in countries such as Ireland, where significant health reform is underway. In this paper, we use Ireland as a case study to explore whether and how public health responses to homelessness during COVID-19 hold important insights for the development of more effective health policy. Drawing on publicly available Irish data, we present a secondary analysis of COVID-19 infection rates amongst homelessness service users as well as trends in emergency accommodation usage between 2020 and 2021. Focusing specifically on public health measures implemented during the pandemic via the health and housing systems, respectively, we discuss how such interventions may have impacted on these homelessness figures in both intended and unexpected ways. We conclude by teasing out and unpacking relevant lessons for health reform.

Published: October 2023

Les technologies immersives sont de plus en plus présentes dans le contexte éducatif. Même si certaines méta-analyses ont montré un résultat positif de certaines technologies immersives TI (Chen et al., 2020; Coban et al. 2022), nous devons encore explorer ses applications pratiques dans les classes. Les avantages pédagogiques ont été mentionnés à plusieurs reprises (Freina et Ott, 2015, Di Natale et al., 2020), mais ils peuvent être modérés par de nombreux défis dans la salle de classe. Dans cet article, nous avons proposé de faire la lumière sur deux études de cas d’exploitation pédagogique de la technologie immersive à l’aide de casques au niveau secondaire en univers social. Les expériences ont été documentées par des groupes de discussion avec les élèves et des entretiens individuels avec les enseignants. Le premier cas proposait d'explorer le conflit en Syrie sous différents angles, avec l'aide de vidéos à 360° et d’une application de visualisation de lieux dans le monde. Le second cas visait à amener les élèves à comparer la réalité passée et présente dans le contexte de Pékin, à partir de vidéos à 360° en réalité virtuelle. Les résultats ont montré que les TI ont un certain potentiel, mais que de nombreuses conditions doivent être mises en place pour en arriver à un usage pédagogique efficace.
Enjeux systémiques du codéveloppement d’outils numériques en soutien à la formation : une confrontation entre dispositions et obstacles

Published: October 2023

Dans un contexte de transition numérique et de pénurie de main-d’œuvre en éducation, le personnel enseignant est demandeur d’outils innovants pour réaliser son travail et optimiser ses actions. C’est ce contexte qui a lancé un projet de codéveloppement d’outils numériques qui vise la prévention de l’incapacité de travail d’élèves en adaptation scolaire réalisant des stages en entreprise. La recherche-action porte une volonté d’innovation, soutenue d’une part par un processus de codéveloppement avec le personnel scolaire et, d’autre part, par la mobilisation d’une approche sensible au genre. L’article fait état du processus de codéveloppement, de l’innovation développée, de même que des obstacles qui sont apparus pendant le projet. Ces derniers se rapportent principalement à trois catégories : les compétences numériques du personnel enseignant et des élèves, la charge de travail et le soutien organisationnel influençant l’innovation numérique. Ces contraintes freinent la volonté d’innovation présente chez toutes les personnes participantes qui reconnaissent l’avantage des nouveaux outils et leur impact positif sur le travail. Les obstacles et dispositions seront présentés en perspective des facteurs systémiques qui les amplifient afin de réfléchir aux conditions nécessaires à l’innovation numérique en éducation.

Published: October 2023

En 2019, Bernard et Fluckiger titrent en introduction : « Innovation technologique, innovation pédagogique : une relation riche et contrastée ». Ils mettent en exergue les discours injonctifs des pouvoirs publics. Pourtant, selon Cros (1997), l’innovation est « le poumon de l’école ». Dans ce contexte contrasté, nous proposons une approche systémique. D’abord, nous quantifions trois communications institutionnelles, révélateurs des objectifs de l’exosystème. Dans cet environnement prescriptif pouvant conduire au rejet, nous présentons ensuite un microsystème de formation destiné à des sujets : des étudiants-professeurs. Nous évaluons alors les productions des étudiants-professeurs à l’aide de critères observant l’innovation technopédagogique. Enfin, nous tentons de déterminer des contraintes et des leviers en formation autorisant l’innovation technopédagogique.

Hypertension is an increase in systolic blood pressure exceeding 140 mmHg and diastolic blood pressure exceeding 90 mmHg. The long-term impact of high blood pressure can lead to damage to various organs such as the heart, kidneys, and brain. In 2019, 34 percent of the population in Jakarta experienced the risk of hypertension, both mild and severe. Based on data from the Cipayung District Health Center in 2022, hypertension ranked first among the top 10 most frequently visited diseases on a monthly basis. This research aims to study and explain the relationship between lifestyle and the occurrence of hypertension in outpatients at the Cipayung District Health Center during the period of January-April 2023. The study design of this research is cross-sectional. Data collection is sourced from secondary data obtained from the medical records of the Cipayung District Health Center. The population in this study consists of outpatients who visited the Cipayung District Health Center with data collected from January to April 2023, totaling 1152 individuals, and all of them were analyzed.

Based on the analysis results, it is known that age, gender, education level, physical activity, and salt consumption significantly influence the occurrence of hypertension. Physical activity is the most dominant risk factor influencing the occurrence of hypertension with an odds ratio of 29.714 and a 95% confidence interval of 19.543 - 45.178. Therefore, it is expected that the health center can enhance health promotion efforts and interventions targeting at-risk groups to prevent hypertension in the Cipayung Health Center area. Additionally, establishing sports clubs and healthy Diet Community Kitchens that can be participated in by the community can be beneficial. Increasing community engagement in healthy living can also reduce the risk of hypertension in the population.

आधुनिक यग में मानव अधिक से अधिक भोग विलासिता का जीवन व्यतीत कर रहा है जो जीवन शैली मानव ने अपनायी है वह निरंतर उसे रोगग्रस्त कर रही है विभिन्न प्रकार के रोग अपने लक्षणों के साथ मानव जीवन के स्वास्थ्य को विकृत कर रहे हैं इन्हीं रोगों की श्रृंखला में आज हृदय से संबंधित अनेक रोग मानव जीवन में अपना डेरा जमाए हुए हैं । प्रत्येक दूसरे व्यक्ति में यह रोग सरलता से देखने को मिलता है जिसके अनेक प्रकार के लक्षण श्वास तेजी से चलना, अधिक गुस्सा आना ,रक्तचाप का अनियंत्रित रहना ,एन्जाइना पेन आदि सामने आते हैं । इनके आधार पर यह जाना जा सकता है कि कहीं ना कहीं हमारा हृदय प्रभावित हो रहा है । अतः यह कह सकते हैं कि हृदय रोग ऐसी स्थितियों का एक समूह है जिनके कारण रक्त वाहिकाएं और हृदय दोनों ही प्रभावित होते हैं इन्हीं स्थितियों में हृदय से संबंधित सभी लक्षण परिलक्षित होने आरंभ हो जाते हैं। इनका कारण सर्वप्रथम हमारा आहार है सही पोषण का ना लेना, धूम्रपान आदि मादक पदार्थों का सेवन करना ,अपनी दिनचर्या में व्यायाम का सम्मिलित ना होना आदि है । यदि यह व्यवहार हमारे दिनचर्या के प्रति रहता है तो यह मानव स्वास्थ्य के लिए एक बहुत ही बड़ा खतरा है । अपने इस शोध पत्र में हम हृदय रोगों से संबंधित जो भी कारण है और उनका योग द्वारा कैसे प्रबंध किया जाए /क्या भूमिका रहेगी मानव जीवन में योग की हृदय रोगों को नियंत्रित करने में यह बतलाने का प्रयास करेंगें। क्योंकि योगाभ्यास ही है जो समस्त रोगों से सुरक्षित रखते हुए शारीरिक एवं मानसिक रूप से स्वस्थ रख सकता है। इस सन्दर्भ में नेशनल हेल्थ स्टेटिस्टिक्स की रिर्पोट में बताया गया है कि “The word yoga has been described as action leading to the union of the body and the mind which improves physical, mental and spiritual well being. It is an ancient art of mind-body control that originated in India over five thousand years ago and is now widely popular throughout the world. The National Health Statistics report that about 21 million adults living in the United States use yoga as a complementary health approach”

Improving Unsupervised Domain Adaptation via Multiple Adversarial Learning

Published: October 2023

Most machine learning methods assume the training and test sets to be independent and have identical distributions. However, this assumption does not always hold true in practical applications. Direct training usually induces poor performance if the training and test data have distribution shifts. To address this issue, a three-part model based on using a feature extractor, a classifier, and several domain discriminators is adopted herein. This unsupervised domain adaptation model is based on multiple adversarial learning with samples of different importance. A deep neural network is used for supervised classification learning of the source domain. Numerous adversarial networks are used to constitute the domain discriminators to align each category in the source and target domains and effectively transfer knowledge from the source domain to the target domain. Triplet loss functions—classification loss, label credibility loss, and discrimination loss—are presented to further optimize the model parameters. First, the label similarity metric is designed between the target and source domains data. Second, a credibility loss function is proposed to obtain an accurate label for the unlabeled data of the target domain under training iterations. Finally, a discrimination loss is designed for multiple adversarial domain discriminators to fully utilize the unlabeled data in the target domain during training. The discrimination loss function uses predicted label probabilities as dynamic weights for the train data. The proposed method is compared with mainstream domain adaptation approaches on four public datasets: Office-31, MNIST, USPS, and SVHN. Experimental results show that the proposed method can perform well in the target domain and improve generalization performance of the model.

Published: October 2023

Casting defects encompass a broad spectrum of imperfections, such as blow holes, pinholes, burrs, shrinkage defects, and various metallurgical anomalies. Detecting these defects manually requires a trained eye, and even the most diligent inspectors can inadvertently overlook subtle irregularities. To address these challenges, there is a growing movement toward automation in quality control. Deep learning models, including the Xception model, are being harnessed to create a robust classification system. Such models have the capacity to analyze thousands of product images with precision, identifying defects that may elude human inspectors. Furthermore, data augmentation techniques are applied to enhance the dataset, allowing the model to generalize more effectively and improve its defect recognition capabilities.
