Published: December 2023

Abstract
Titanium and its alloys are extensively used for medical implant material due to their superior biocompatibility, corrosion resistance, and strength. However, fabrication of corrosion free titanium and its alloys is still a challenging task since it might affect the surrounding tissues. Therefore, some protection is needed to enhance the performance of the implants in the body in terms of biocompatibility and corrosion resistance. In this work, the hybrid of gelatin-based forsterite–hydroxyapatite synthesized by the sol–gel process was coated by dip-coating on titanium alloy (Ti6Al4V). The variable concentration effects of forsterite–hydroxyapatite in gelatin matrix and the coating applications on the surface morphology as well as corrosion performance of coated substrates were evaluated. The electrochemical corrosion behaviour was investigated through Tafel polarization curves. Outcomes show that the substrate prepared with 5 wt.% of forsterite–hydroxyapatite has a maximum corrosion resistance, crack-free coating, is hermetic and adherent to the substrate.

Published: December 2023

Abstract
Addressing the complex problem of 6D pose estimation from single RGB images is essential for robotics, augmented reality, and autonomous driving applications. The aim of this study is to overcome limitations in handling scenes with high object occlusion and clutter. We introduce an attention-driven end-to-end model that builds upon existing methods employing pixel-wise unit vectors and voting for object keypoints. Integrating attention mechanisms allows the model to focus computational resources on salient features, enhancing accuracy. Experimental results using the LINEMOD benchmark dataset demonstrate an accuracy rate of 99.73%, outperforming state-of-the-art approaches. The model also exhibits strong generalization capabilities, achieving an average accuracy of 97.36% on objects not included in the dataset. This work concludes that the attention mechanism significantly elevates the performance and robustness of 6D pose estimation, particularly in challenging environments, and opens new avenues for real-world applications.
Getting “good” data in a pandemic, part 1: assessing the validity and quality of data collected remotely
Authors: Kostadinova Viktorija , Gardner Matt Hunt 
Published: December 2023

Abstract
The articles presented in this special issue contribute to recent scholarship on remote data collection. The topics covered can be described in terms of two focal areas. The first focus is on the ways in which research can be adapted to remote data collection, and the second on the ways in which data collected remotely should be considered alongside data collected using “traditional” methods. The overarching epistemological question uniting these focal areas is whether remote data collection yields data of substantive quality. While varied in their aims and approaches, the studies presented suggest that remote data collection methods can be used on a par with traditional approaches, thus aligning with the findings of already existing scholarship on remote data collection methods. The detailed findings presented in the papers provide valuable methodological information for further development of methods in sociolinguistics and related areas. Though these studies originated in conditions when remote data collection was the only option, they reveal the suitability of remote data collection methods beyond the COVID-19 pandemic. Remote methods can get “good” data; the experience of conducting fieldwork during the pandemic, while a challenge, was a catalyst for creativity, innovation, and enrichment in the field.
Predation of the black-eared opossum (Didelphis aurita) on the great kiskadee (Pitangus sulphuratus) and the water rat (Nectomys squamipes)

Published: December 2023

Abstract
Understanding the predatory behavior of a species is critical to its ecological role. Little is known about the predatory behavior of the marsupial Didelphis aurita. Here, we present two cases to shed light on its opportunistic nature: an opossum struggling to locate and attack an immobile juvenile bird, indicating olfactory detection and visual constraints, and an opossum carrying a weakened rat that was host of four blowfly larvae. These events reinforce D. aurita’s opportunistic behavior in attacking debilitated vertebrates.

Published: December 2023

Abstract
The coronavirus disease 2019 (COVID-19) pandemic prompted several countries to implement measures restricting people’s movements. This situation presented an opportunity to understand the acoustic environment experienced by the population during that time. This study aims to assess the impact of the soundscape in the home office environment during the pandemic. A survey was carried out using an online survey to collect data on the work environment before and during the pandemic. The questions identified the predominant sound sources using pre-defined taxonomy and non-parametric statistical tests. The findings underscore the common occurrence of multitasking during work from home and its correlation with decreased workplace quality. Notably, exterior sounds received lower pleasantness ratings compared to interior sounds, and the presence of human and mechanical sounds had a more significant impact on the overall assessment of workplace quality. Individuals who live in apartments or mixed-use areas tend to perceive outdoor sounds less favorably than those who live in houses or residential areas. On the other hand, individuals who live with two or more people tend to perceive indoor sounds more unfavorably than those who live alone. This study contributes to the ongoing discussion about the influence of the soundscape during the pandemic and mobility restrictions on the quality of home office environments.

Abstract
This literature review aims to analyze available data on minimally invasive surgery (MIS) for the surgical treatment of endometrial cancer (EC) in obese patients and compare the surgical outcomes of patients with EC, treated with robotic and laparoscopic hysterectomy. An extensive literature search was conducted about studies on obese EC women who underwent robotic or laparoscopic hysterectomy. MIS reduces the impact of common adverse effects in obese patients. The robotic approach can ensure many advantages: reduction in blood loss, operative time, and hospital stay; indeed, robotic surgery seems to add other benefits when lymphadenectomy is required. Robotic surgery is more expensive compared to other approaches but considering global cost, this is less expensive than abdominal hysterectomy and its cost decreases with increasing procedural volume. Intra, peri and post-operative outcomes of obese patients with endometrial carcinoma treated with mininvasive surgery have been analyzed, highlighting the advantages and disadvantages of this approach. However, the gold standard between classical laparoscopy and robotic laparoscopy has not been defined. Robotic surgery shows better surgical outcomes, but its potential is limited due to its costs and long operating times. However, oncologic outcomes remain the most important aspects and are still to be defined.

Abstract

Objectives
The rise in opioid prescriptions with a parallel increase in opioid use disorders remains a significant challenge in some developed countries (opioid epidemic). However, little is known about opioid consumption in low- and middle-income countries (LMICs). In this short report, we aim to discuss the increase in opioid consumption in LMICs by providing an update on the opioid perspective in Brazil.

Methods
We analyzed opioid sales on the publicly available Brazilian Health Regulatory Agency (ANVISA) database from 2015 to 2020.

Results
In Brazil, opioid sales increased 34.8 %, from 8,839,029 prescriptions in 2015 to 11,913,823 prescriptions in 2020, this represents an increase from 44 to 56 prescriptions for every 1,000 inhabitants. Codeine phosphate combined with paracetamol and tramadol hydrochloride were the most common opioids prescribed with an increase each year.

Conclusions
The results suggest that opioid prescriptions are rising in Brazil in a 5 years period. Brazil may have a unique opportunity to learn from other countries and develop consistent policies and guidelines to better educate patients and prescribers and to prevent an opioid crisis.

El rápido incremento de la “esclavitud moderna” se explica en la severidad de las políticas migratorias de los países ricos, las contrageografías de la globalización, la crisis económica mundial, la creciente feminización de la pobreza y la transformación de las economías de mercado en sociedades de mercado. Colectividades en las que se propugna un modelo de vida basado en la satisfacción inmediata de los deseos, por lo que todo parece susceptible de ser vendido o comprado; todo puede ser objeto de mercantilización. Una banalización del consumo que ignora la situación y el contexto específico de ese otro cuyo cuerpo o fuerza que se compra. La vulnerabilidad y la demanda son, en consecuencia, “el alfa y omega” de la trata. Un “demonio amorfo” que encarna una variedad de posturas (moralistas, ideológicas y de seguridad) que justifican respuestas principalmente antimigratorias y criminalizadoras. Supuestas soluciones que sólo ponen las cosas peor.

En este artículo presentamos el resumen de los resultados de la excavación arqueológica desarrollada en la Cañada Honda de Itálica entre los años 2017 y 2019. Gracias a esta actividad se ha podido excavar parte de la crujía que conforma la cabecera de la domus del mismo nombre, abordando también la documentación y análisis arqueológico de las estructuras que hasta ahora se encontraban a la vista, resultado de excavaciones previas a nuestra intervención. Igualmente, los nuevos datos estratigráficos aportados por la excavación han permitido ajustar la datación del abandono de la casa, que situamos en la segunda mitad del s. III d.C., momento a partir del cual se produce el expolio y derrumbe del edificio.
Junto e ello, también se han llevado a cabo nuevas prospecciones geofísicas en el ángulo suroeste de la muralla tardoantigüa de Itálica, posteriormente contrastadas mediante la excavación de sondeos. Estos trabajos han permitido identificar por primera vez la muralla tardoantigua de Itálica, definir sus peculiaridades formales y conocer sus técnicas constructivas, caracterizadas por la reutilización de materiales de expolio, así como proponer para su construcción una datación que situamos entre la segunda mitad del s. IV y la primera mitad del s. V.

Published: December 2023

Microorganisms are the most common sources of commercial enzymes due to their physiological and biochemical properties, facile culture conditions, and ease of cell manipulation. Among microbial enzymes, proteases are ubiquitous in nature and have been found in all living forms encompassing the eukaryotes like plants, animals, fungi, and protists as well as the prokaryotic domains of bacteria and archaea. Proteases are the most important for the industry and constitute approximately 60% of the total industrial enzyme market. Among the bacteria, the genus Bacillus has a very prominent place in terms of the commercial production of proteases. Earlier from the water and bottom sediments of the Black Sea, we have isolated a number of producers of proteolytic enzymes from Bacillus species. The aim of this work was to investigate the ability of representatives of a number of soil bacilli species to synthesize enzymes that hydrolyze such protein substrates as elastin, fibrin, fibrinogen, and keratin. Methods. The objects of the study were 8 cultures (KS 1 — KS 8) isolated from the soil of the rice agrocenosis. Cultures were grown under conditions of deep cultivation at 28 °С, with a mixing speed of for the nutrient medium of 230 rpm for 4 days. Methods of determining proteolytic (caseinolytic, elastolytic, fibrinolytic, fibrinogenolytic, and keratinase) activity in the culture liquid supernatant were used. Disulfide reductase activity was measured spectrophotometrically at 412 nm by evaluating the yellow sulfide formed during the reduction of 5,5’-dithiobis-(2-nitrobenzoic acid) (DTNB). Results. The study of the spectrum of proteolytic activities of 8 freshly isolated strains showed that only KS 6 under experimental conditions did not show the ability to hydrolyze any of the studied substrates (casein, elastin, fibrin, fibrinogen, and keratin). Strains KS 1, KS 2, KS 7, and KS 8 showed higher levels of activity compared to other strains studied. The most interesting for further research are: І) strain KS 1, which showed the highest fibrinolytic activity, ІІ) strain KS 2 as the most effective producer with elastase and fibrinogenolytic activity, III) KS 7 and KS 8, which simultaneously showed the highest rates as keratinase (7 U/mL and 9 U/mL) and sulfate reductase (33 μmol/min and 31 μmol/min) activity, respectively. Conclusions. According to the catalytic properties, a number of representatives of Bacillus, isolated from the soil of the rice agrocenosis may be promising for further research as an enzyme producer with proteolytic activity.
Une vie avec Léon Cordes (1913-1987)
Authors: Pech Rémy 
Published: December 2023

Léon Cordes (1913-1985) est imprégné d’un héritage culturel où se mêlent, de Minerve à Argeliers, le souvenir des cathares, la Croisade menée contre eux au XIIIème siècle, et, tout proche, celui de la révolte vigneronne de 1907. Dès les années 1930, il prend part à l’éclosion d’un occitanisme entièrement renouvelé, aux côtés de Charles Camproux, puis de Robert Lafont et Max Rouquette. Auteur de théâtre et rédacteur de revues, poète sensible, il revendique le profil singulier d’un paysan viscéralement lié à sa terre, mais maîtrisant toutes les disciplines littéraires pour s’engager par la création dans la défense et le développement d’une langue et d’une civilisation occitanes passionnément vécues. Le présent article, né de l’admiration et de l’amitié, s’efforce de restituer les grandes étapes d’un parcours insuffisamment reconnu, celui d’un écrivain-paysan dont le profond enracinement s’est accompagné d’une ouverture délibérée à la modernité.

AbstractBronze vessels as grave goods in the burial of the Vicus at Biatorbágy. In the eastern area of Biatorbágy, north of the Autostrada / No 100, around the tenth kilometer stone in 1991, 1995, 2004 heading the planned construction works rescue excavations were carried out. Here several Roman bronze vessels, probably grave goods, were excavated. This necropolis belonged to the Roman vicus at Biatorbágy. Different types of vessels, a wine jug with a round opening, a handled dish for hand washing, on which are a depiction of a sleeping African and Bacchic attributes, a water jug with a spout, some fragments belonging to bucket or cauldron, a second water jug with sharp projecting shoulder, a jug with round mouth and decorated handle, a bath-saucer came to light. The first jug – compiled from old parts – a strange creation by a local master, was originally produced at the end of the 1st century A.D. The handled dish and the bath-saucer were fabricated at the end of the 1st century A.D.–beginning of the 2nd century A.D. Both water jugs were made around the middle of the 2nd century A.D.
Tracing the road of elephant ivory at the end of Late Antiquity – Archaeometric analysis of ivory artefacts from the 6th–7th-century Carpathian Basin

Published: December 2023

AbstractElephant ivory, a prestigious and valuable raw material in the post-Roman West and Byzantium between the 5th and 7th centuries AD, may originate from various sources. While both written and art historical evidence suggests that in the case of early medieval artefacts, African provenance is more likely than Asian, no data at hand is conclusive. The present paper investigates, with the help of FTIR and Raman spectroscopy, carbon and nitrogen concentration and nitrogen isotope (δ15N) analyses, the material resources of elephant ivory artefacts discovered in 6th- and 7th-century AD archaeological context in the Carpathian Basin to contribute to our understanding of late antique long-distance trade networks and economic relations.
Development, validation and greenness assessment of environmentally friendly analytical methods for the quantification of lenalidomide in pharmaceutical formulations
Authors: Demir İbrahim , Bulduk İbrahim , Enginar Hüseyin 
Published: December 2023

AbstractLenalidomide is a drug that has immune-modulating, anti-angiogenic, and anti-inflammatory properties. In this study, we developed green HPLC and spectrophotometric methods to determine the concentration of lenalidomide in pure and pharmaceutical formulations. In the HPLC method, 10 mM potassium dihydrogen phosphate solution (pH: 2.0) and ethanol (50:50, V/V) were used as mobile phases, isocratic elution was applied at a flow rate of 1.0 mL min−1 and detection was made at 304 nm. In the spectrophotometric method, the spectral patterns of standard solutions in different solvents were comprehensively examined, the best spectra were obtained with ultrapure water, and a wavelength of 304 nm was selected for detection. Both methods have been validated according to ICH guidelines for various parameters. Correlation coefficients greater than 0.999 were determined for both methods in the concentration range of 5–30 μg mL−1. The developed methods were applied to commercial formulations, and comparisons of the results were made using the Student (t) test for means and the Fischer (F) test for standard deviations. No statistically significant difference was observed between the methods. The greenness evaluation of these methods was carried out using AGREE software. The developed methods are proposed as excellent environmental and operator-friendly alternatives for the quantification of Lenalidomide in pharmaceutical formulations.

Published: December 2023

El bajo conocimiento del adecuado manejo de los residuos peligrosos que son generados en los talleres de mantenimiento mecánico en la calle sexta de la ciudad de Bogotá contribuye en la contaminación de recursos naturales como el agua, el aire, el suelo, entre otros. Estos talleres deben contar, por normativa, con una gestión sobre estos residuos peligrosos en el que se contemple zonas impermeabilizadas que evite derrames o vertimientos en cuerpos de agua, un adecuado almacenamiento que impida emisiones al aire, contar con permisos y planes de contingencia y el Registro de Generadores de Desechos o Residuos Peligrosos (RESPEL) entre otros trámites requeridos para este sector.
Por lo anterior, cobra importancia plantear un plan de capacitación, dirigido a los dueños y trabajadores de los talleres, orientado a la sensibilización y búsqueda participativa de mejoras y soluciones para generar un adecuado manejo de los residuos peligrosos y con ello contribuir en el cuidado y conservación de los recursos naturales.
El plan de capacitación propuesto les orientará desde el autoaprendizaje a cómo evitar y/o minimizar impactos al medio ambiente, a partir de la sensibilización, reflexión y aporte de los mismos dueños y trabajadores, ideas que serán indispensables para que el proceso se lleve a cabo con éxito.
