Among the Mediterranean aromatic plants, Ruta tuberculata Forssk. (Rutaceae) has been widely used as a traditional natural remedy against various disorders resulting from its divers’ pharmacological virtues. The aim of this study is to characterize for the first time the phenolic profile of its ethyl acetate (EtOAcE) and acetonic (AcE) extracts and to screen their in vitro antioxidant, antidiabetic, and neuroprotective activities. Phenolic content was determined using spectrophotometric and cLC-DAD analysis. Pharmacologically, in vitro antioxidant power was evaluated using six different antioxidant methods. Moreover, the antidiabetic and neuroprotective capacities were assessed in vitro by determining the α-amylase, α-glucosidase, and acetylcholinesterase inhibitory activities. Phytochemically, the highest flavonoid content was found in EtOAcE where the major identified compounds were myrecetin, rutin, sylimarin, naringenin, and quercetin. In presence of other phenolic acids, gallic acid was exclusively detected in AcE. Furthermore, both R. tuberculata extracts showed significantly remarkable antioxidant activities, especially the EtOAcE. Interestingly, AcE strongly inhibited the acetylcholinesterase and α-glucosidase, with the respective IC50 values of 20.48 ± 0.2 and 104.5 ± 1.8 µg/mL. In this study, we also reported the nutritional quality associated with the identified phytocompounds. R. tuberculata organic extracts may offer exciting reserves to achieve new anti-diabetic and anti-Alzheimer drugs which have also antioxidant potential.

Previous studies demonstrated sex-related differences in several areas of the human brain, including patterns of brain activation in males and females when observing their own bodies and faces (versus other bodies/faces or morphed versions of themselves), but a complex paradigm touching multiple aspects of embodied self-identity is still lacking. We enrolled 24 healthy individuals (12 M, 12 F) in 3 different fMRI experiments: the vision of prototypical body silhouettes, the vision of static images of the face of the participants morphed with prototypical male and female faces, the vision of short videos showing the dynamic transformation of the morphing. We found differential sexual activations in areas linked to self-identity and to the ability to attribute mental states: In Experiment 1, the male group activated more the bilateral thalamus when looking at sex congruent body images, while the female group activated more the middle and inferior temporal gyrus. In Experiment 2, the male group activated more the supplementary motor area when looking at their faces; the female group activated more the dorsomedial prefrontal cortex (dmPFC). In Experiment 3, the female group activated more the dmPFC when observing either the feminization or the masculinization of their face. The defeminization produced more activations in females in the left superior parietal lobule and middle occipital gyrus. The performance of all classifiers built using single ROIs exceeded chance level, reaching an area under the ROC curves > 0.85 in some cases (notably, for Experiment 2 using the V1 ROI). The results of the fMRI tasks showed good agreement with previously published studies, even if our sample size was small. Therefore, our functional MRI protocol showed significantly different patterns of activation in males and females, but further research is needed both to investigate the gender-related differences in activation when observing a morphing of their face/body, and to validate our paradigm using a larger sample.

Published: August 2022

There is evidence that PM2.5 could be obesogenic. Lima is one of the most polluted cities in South America, with an increasing prevalence of childhood obesity. This study aimed to determine the association between PM2.5 exposure of children aged 6 to 59 months and being overweight or obese (O/O) in a significant dataset survey. Cases were defined when weight for height Z-score (WHZ) was >2 standard deviations (SD) from the mean, for each sex. A control was defined when WHZ was between ±2 SD. We used a conditional logistic regression model to calculate the odds ratio (OR) between extrauterine and intrauterine PM2.5 exposure and O/O. Extrauterine PM2.5 exposure was evaluated as a 6-month PM2.5 mean prior to the survey. We found a significant association between O/O and extrauterine (OR: 1.57, 1.51–1.63) and intrauterine (OR: 1.99, 1.88–2.12) PM2.5 exposure for an increment of 10 μg/m3. The ORs increased as the quartile increased in both exposures. We observed a higher association in children aged 6–11 months (OR: 3.07, 2.84–3.31). In conclusion, higher levels of PM2.5 in Lima and Callao were associated with cases of O/O in children from 6 to 59 months, with the association higher for prenatal exposure.
Aflatoxins in Maize: Can Their Occurrence Be Effectively Managed in Africa in the Face of Climate Change and Food Insecurity?
Authors: Nji Queenta Ngum , Babalola Olubukola Oluranti , Mwanza Mulunda
Published: August 2022

The dangers of population-level mycotoxin exposure have been well documented. Climate-sensitive aflatoxins (AFs) are important food hazards. The continual effects of climate change are projected to impact primary agricultural systems, and consequently food security. This will be due to a reduction in yield with a negative influence on food safety. The African climate and subsistence farming techniques favour the growth of AF-producing fungal genera particularly in maize, which is a food staple commonly associated with mycotoxin contamination. Predictive models are useful tools in the management of mycotoxin risk. Mycotoxin climate risk predictive models have been successfully developed in Australia, the USA, and Europe, but are still in their infancy in Africa. This review aims to investigate whether AFs’ occurrence in African maize can be effectively mitigated in the face of increasing climate change and food insecurity using climate risk predictive studies. A systematic search is conducted using Google Scholar. The complexities associated with the development of these prediction models vary from statistical tools such as simple regression equations to complex systems such as artificial intelligence models. Africa’s inability to simulate a climate mycotoxin risk model in the past has been attributed to insufficient climate or AF contamination data. Recently, however, advancement in technologies including artificial intelligence modelling has bridged this gap, as climate risk scenarios can now be correctly predicted from missing and unbalanced data.
An Overview of the Anatomical Distribution of Tetrodotoxin in Animals
Authors: Melnikova Daria I. , Magarlamov Timur Yu.
Published: August 2022

Tetrodotoxin (TTX), a potent paralytic sodium channel blocker, is an intriguing marine toxin. Widely distributed in nature, TTX has attracted attention in various scientific fields, from biomedical studies to environmental safety concerns. Despite a long history of studies, many issues concerning the biosynthesis, origin, and spread of TTX in animals and ecosystems remain. This review aims to summarize the current knowledge on TTX circulation inside TTX-bearing animal bodies. We focus on the advances in TTX detection at the cellular and subcellular levels, providing an expanded picture of intra-organismal TTX migration mechanisms. We believe that this review will help address the gaps in the understanding of the biological function of TTX and facilitate the development of further studies involving TTX-bearing animals.
Subtidal Dynamics in a Tidal River with Limited Discharge

Published: August 2022

Investigating subtidal friction and mass transport is pivotal for examining subtidal dynamics in tidal rivers. Although the behavior of subtidal friction and transport has been discussed in recent years, most studies have been conducted on tidal rivers that are affected by high amounts of river runoff. The aim of this study is to offer an initial understanding of the spatial and temporal behaviors of subtidal friction and subtidal flux in a tidal river channel with limited river runoff. This study utilized the frequency domain and theoretical decomposition analyses to determine the dominant tidal and subtidal mechanisms. Frequency domain analysis indicated the dominance of semidiurnal and diurnal tides in the observed tidal river channel. The rate of energy transfer owing to shallow water interaction was found to be stronger for the current velocity than for the water elevation. Decomposition analysis showed that subtidal friction and flux in a low-discharge tidal river channel were largely influenced by subtidal flow-induced subtidal friction and Eulerian return flux, respectively. The key findings of this study are as follows: (i) the limited amount of river runoff (4–20 m3/s) leads to the vertical variability of subtidal friction contributions from subtidal flow and subtidal-tidal interaction, as well as Eulerian return flux, and (ii) the vertical variability of the aforementioned terms can be associated with the existence of influential longitudinal subtidal density gradients along the tidal river. We believe that these findings advance our understanding of subtidal dynamics in tidal river systems, particularly those with limited discharge.
Laboratory Development of an AI System for the Real-Time Monitoring of Water Quality and Detection of Anomalies Arising from Chemical Contamination
Authors: Czyczula Rudjord Zofia , Reid Malcolm J. , Schwermer Carsten Ulrich , Lin Yan
Published: August 2022

Monitoring water quality is critical for mitigating risks to human health and the environment. It is also essential for ensuring high quality water-based and water-dependent products and services. The monitoring and detection of chemical contamination are often based around a small set of parameters or substances. Conventional monitoring often involves the collection of water samples in the field and subsequent analyses in the laboratory. Such strategies are expensive, time consuming, and focused on a narrow set of potential risks. They also induce a significant time delay between a contamination event and a possible reactive measure. Here, we developed a real-time monitoring system based on Artificial Intelligence (AI) for field deployable sensors. We used data obtained from full-scan UV-spec and fluorescence sensors for validation in this study. This multi-sensor system consists of (a) anomaly detection that uses multivariate statistical methods to detect any anomalous state in an aqueous environment and (b) anomaly identification, using Machine Learning (ML) to classify the anomaly into one of the a priori known categories. For a proof of concept, we tested this methodology on a supply of municipal drinking water and a few representative organic chemical contaminants applied in a laboratory-controlled environment. The outcomes confirm the ability for the multi-sensor system to detect and identify changes in water quality due to incidences of chemical contamination. The method may be applied to numerous other areas where water quality should be measured online and in real time, such as in surface-water, urban runoff, or food and industrial process water.

Authors:   Altai State University,Barnaul, Prasolova I.A , Vasilenko Ju.E. ,   Altai State University, Barnaul
Published: August 2022

Recently, atypical labor relations have become increasingly common. The share of remote workers in the labor market is increasing every year. Meanwhile, the performance of labor duties outside the location of the employer creates certain specificity in the implementation of constitutional guarantees for work in conditions that meet the requirements of safety and hygiene. It should be recognized that the lack of a special assessment of the working conditions of remote workers, as well as a significant reduction in the scope of the employer's obligations in the field of labor protection of such employees create a real threat of abuse of the right by employees and employers. In the article, the authors analyze some of the problems that arise in the field of legal regulation of the labor protection of remote workers, law enforcement practice, and also suggest ways to improve labor legislation in this area.

Published: August 2022

Introdução. Programas de intervenção precoce (IP) são implementados após o nascimento e até os três anos de idade e objetivam minimizar atrasos do desenvolvimento infantil e promover a saúde e o desempenho global familiar. A organização dos serviços de IP passou por diferentes estágios ao longo dos anos. A Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) permitiu incorporar o modelo Biopsicossocial no planejamento das intervenções. Objetivo. Analisar como a abordagem da funcionalidade evoluiu ao longo do tempo nos programas de IP sob a perspectiva dos conceitos e domínios da CIF. Método. Realizou-se uma revisão integrativa nas bases de dados Scielo, PEDro, Lilacs e PubMed com as estratégias de busca: "child development" AND "early intervention" AND functioning; "child development” AND "early intervention" AND disability; "child development" AND "early intervention" AND disabilities. Os critérios de inclusão foram: ensaios clínicos que estudaram práticas de IP em crianças com idade entre zero e três anos. Resultados. 23 artigos foram incluídos. Observou-se que as práticas que integram as várias perspectivas da funcionalidade e destacam a abordagem biopsicossocial são recentes, publicadas em sua maioria na última década. Conclusão. Conforme a família assumiu o protagonismo na condução das intervenções, os programas passaram a individualizar os cuidados de acordo com as necessidades específicas de cada uma e a funcionalidade passou a ser abordada em sua totalidade pelas intervenções, com os artigos mais recentes abordando os domínios Funções do corpo, Atividade, Participação e Fatores Contextuais.

Published: August 2022

Suite aux mouvements de contestation survenus en 2011, la Tunisie a connu la fin du régime dictatorial de Ben Ali et l’avènement d’une République fondée sur une constitution résolument tournée vers la transparence du régime. Les réformes engagées ont conduit l’administration et les collectivités à repenser la diffusion de l’information et l’accès des citoyens aux documents administratifs. Suite au constat des difficultés des collectivités, notamment les plus récentes, à se mettre en conformité avec la nouvelle réglementation, le Centre de formation et d’appui à la décentralisation (CFAD), accompagné de la Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ), qui est un organisme de coopération internationale allemand, a décidé de créer un module de formation destiné spécifiquement aux agents des collectivités en charge des archives et de leur communication. Retour sur la création de ce module de formation et de son déploiement par le CFAD.
Transparence choisie et transparence retrouvée : les fonds LGBTQI et féministes à Lyon
Authors: Hoppe Élodie , Isarte Roméo
Published: August 2022

Le questionnement récent autour des archives essentielles est particulièrement sensible lorsqu’il touche les traces de groupes sociaux marginalisés. Les groupes féministes et les communautés LGBTQI sont aujourd’hui au centre de débats de société et la demande de vérité accompagne un mouvement relativement récent de collecte institutionnelle. Faire l’histoire queer et féministe suppose de savoir où chercher. L’hypothèse serait qu’il existe bien entendu des traces mais qu’elles seraient invisibles, voire «invisibilisées » dans les archives institutionnelles. L’association Mémoires minoritaires incarne cette pratique alternative de collecte et valorisation. Son action est motivée par l’affirmation que la conservation d’archives sur les sexualités et les minorités de genre dans des institutions publiques n’est pas une pratique neutre dénuée d’effet sur la société. En écho, les archives du centre Louise Labé de l’université Lyon 2, témoignent d’une transparence retrouvée. Convergence entre militantisme et recherche, ce fonds a souffert du déclin des études qui l’ont initié. Ce retour d’expérience permet de mettre en évidence le rôle central du service d’archivage intermédiaire de l’université, jouant à plein son rôle par la coordination entre productrices du fonds, réseaux militants et institutions d’archivage définitif. Autant d’éléments qui invitent à repenser la stratégie globale de conservation, pour une meilleure transparence.

Le plan de sauvegarde des Archives nationales : la gestion des ressources humaines
Authors: Coste Patricia , Thibault Michel
Published: August 2022

Indispensable dans tout établissement culturel, un plan de sauvegarde ne saurait exister sans une équipe d’agents volontaires, formés et encadrés. Les Archives nationales ont mis en place depuis 2014 une stratégie pour recruter des volontaires disponibles pour intervenir, en cas de sinistre, en dehors des jours et heures habituels de travail. Ces volontaires s’engagent à suivre une formation spécifique. Celle-ci, ouverte largement à tous les agents des Archives nationales qui le souhaitent, comporte à la fois des aspects théoriques, sur l’organisation mise en oeuvre aux Archives nationales, et des aspects pratiques, dans le cadre d’une mise en situation. Une attention particulière est portée à la formation des coordonnateurs et chefs d’équipe chargés d’encadrer les volontaires, qui ont été invités à suivre une formation au «management en situation de crise » . L’efficacité du plan de sauvegarde repose pour beaucoup sur la cohésion de ces encadrants et sur leur capacité à se substituer, lorsqu’une situation d’urgence survient, à la chaîne hiérarchique ordinaire des Archives nationales.
L’innovation numérique : un cercle vertueux pour l’archivistique

Published: August 2022

Le monde des archives a toujours suivi de près les développements numériques pour s’intégrer dans la société que nous connaissons aujourd’hui, où l’information est produite directement sous forme numérique et circule par les réseaux informatiques. La numérisation de nos ressources a touché aussi bien les informations descriptives des archives que les documents eux-mêmes, reproduits par photographie numérique. Ces ressources ont été rapidement mises à disposition sur Internet, dont l’évolution a aussi eu des répercussions sur les modalités de consultation et d’utilisation des archives : à l’accès «statique » , se sont ajoutés les usages du Web 2.0 avec l’enrichissement des contenus par le public ; aujourd’hui résonnent les sirènes des humanités numériques et du linked data, qui nous rappelle l’impérieuse nécessité de l’indexation et la mise au point de référentiels partagés. La tendance n’est plus seulement au signalement des ressources par les métadonnées, mais aussi à l’exploitation du contenu des documents, comme le montrent les projets de transcription collaborative ou encore la reconnaissance des écritures manuscrites. L’archivistique intègre ces avancées, et les deux articles en donneront des exemples, qui ne remettent pas en cause les fondamentaux du métier, mais en rappellent au contraire le haut niveau d’exigence.

Normes internationales et influence française
Authors: Sibille-de Grimoüard Claire
Published: August 2022

La normalisation, si elle a encore une dimension hexagonale, se construit de plus en plus au niveau international. Depuis la fin des années 1990, la communauté archivistique française s’est progressivement impliquée dans le processus de normalisation à l’échelle internationale, consciente que la participation à des groupes d’experts venant du monde entier est l’occasion de croiser les pratiques mais aussi de valoriser l’archivistique française et ses spécificités. La diversité des projets en cours et des domaines investis montrent que la France, de spectatrice, est devenue contributrice, voire actrice, de l’appareil normatif à l’international. Rejoindre les comités et instances de normalisation offre la possibilité d’influencer et de diriger les bonnes pratiques internationales en interagissant avec des professionnels et des idées du monde entier.

« Se priver d’archives, c’est se priver de mémoire » : la dualité central/local du fonds de l’Afrique occidentale française (AOF)
Authors: Chamelot Fabienne
Published: August 2022

Le fonds Afrique occidentale française (AOF) constitue l’exception à la règle de partage entre «archives de souveraineté » et «archives de gestion » appliquée dans les autres colonies ou ex-colonies françaises aux indépendances. Si cette règle de partage émerge explicitement au moment des indépendances, elle est liée à une problématique spécifique aux fonds coloniaux des gouvernements généraux, à la fois administrations centrales et locales. Cette dualité, par conséquent également portée par les fonds, reflète une réalité politique et administrative de l’empire colonial français clivé autour de deux régimes antagonistes, et contribuera, avec d’autres facteurs, à la complexe et chaotique trajectoire des archives en AOF. Jacques Charpy sera le premier, dans les années 1950, à classer ces fonds et à les rendre accessibles en mettant en oeuvre une approche archivistique réaliste et pragmatique. Resté sur le territoire sénégalais, le fonds AOF attire désormais chaque année de nombreux chercheurs aux Archives nationales du Sénégal et reste l’occasion d’initiatives conjointes avec la France.
Le Conseil international des archives, un acteur de la Francophonie archivistique

Héritier de structures internationales de l’entre-deux-guerres, le Conseil international des archives (ICA) est créé à Paris en juin 1948, sous l’égide de l’Unesco. Son organisation est d’emblée prise en charge par les Archives de France qui organisent en 1950 le premier Congrès international des archives à Paris. Dans les décennies suivantes, nombre d’initiatives et de projets sont soutenus ou portés par les archivistes français. Mais la place de la France au sein du Conseil semble avoir reculé depuis quelques années. Pour autant, la Francophonie reste bien représentée au sein de l’ICA.

Published: August 2022

Este estudio se centra en indagar la problemática del ingreso a la universidad en el contexto de pandemia durante el año 2020. La perspectiva metodológica fue exploratoria y tuvo como técnica de recolección de datos un cuestionario digital destinado a estudiantes de primer y segundo año. Las respuestas procesadas fueron 2500. Los resultados muestran desigualdad de condiciones sociotécnicas, de calificación del vínculo con docentes y en la organización de los propios tiempos. Se destacan valoraciones positivas en relación con el trabajo en la virtualidad referidas a la comodidad del hogar, el ahorro de tiempo y dinero y la disponibilidad de materiales pedagógicos. Se señalan asimismo dificultades en la organización, en los procesos de aprendizaje y en el establecimiento de vínculos interpersonales. Finalmente, se describen sentimientos y emociones experimentados durante este período en términos habitualmente negativos, mencionándose algunos como ansiedad y soledad. Las conclusiones muestran problemáticas de diverso orden que debió enfrentar el cuerpo estudiantil de los primeros años de la universidad, entre ellas, la discontinuidad existente entre las vivencias educativas previas y la inserción en el ámbito universitario y las consecuentes dificultades en los procesos de afiliación institucional e intelectual con características específicas debido al contexto de pandemia.

Authors: Dussel Inés
Published: August 2022

En este artículo se analizan los argumentos sobre el fin de la escuela a la luz de la experiencia de la pandemia y desde la perspectiva de la teoría de los medios. Se aborda la escuela como un ecosistema de medios y un ensamble socio-técnico dinámico, que está siendo reorganizado por los medios digitales. Con estas conceptualizaciones, se analizan mapas o diagramas realizados por docentes argentinos durante la pandemia sobre su entorno socio-material. En esas visualizaciones se observa la reorganización de la “escuela sin paredes”, y se debaten algunos de sus efectos sobre la organización escolar y el trabajo docente.

Published: August 2022

Objetivo: Identificar os tratamentos tópicos mais eficazes nas queimaduras de espessura parcial, comparando os diversos tipos de curativos utilizados, a fim de auxiliar na abordagem precoce do paciente, reduzindo o agravo da lesão. Método: Revisão sistemática da literatura, correspondente ao período de 2017 a 2022, cujos dados foram coletados na base de dados PUBMED, LILAC, Medline e SCIELO. Como descritores foram utilizados os termos em português e inglês: queimadura, terapêutica e cicatrização sendo analisados na íntegra 7 artigos. Resultados: Tratamento mais eficaz e com melhor custo/benefício para a abordagem precoce dos pacientes a fim de evitar agravos foram elucidadas nas literaturas investigadas. Desse modo, existem uma série de tratamentos para queimaduras, desde os compostos mais tradicionais como as composições com prata, até outros mais inovadores como a pele de tilápia, e seu uso deve depender de recursos disponíveis, grau e local da queimadura, objetivo do tratamento, entre outros fatores. Conclusão: A partir dos resultados dessa revisão sistemática, foi possível descrever novas propostas de curativos para o tratamento de queimaduras. Foram encontrados como principais tratamento tópico de queimaduras de espessura parcial o uso da pele de tilápia, Aquacel, Película de Biocelulose e Sulfadiazina de Prata. Em suma, a escolha do tratamento tópico deve ficar a critério do profissional buscando sempre o custo benefício, tempo de tratamento, e a disponibilidade desses curativos na instituição de saúde onde trabalham.
Utilização do sabugo de milho na redução do índice de acidez de óleos residuais de fritura visando a produção de biodiesel

O biodiesel se destaca como uma fonte de energia renovável em substituição aos combustíveis fósseis, caracterizando-se como um combustível menos poluente e livre de compostos sulfurados, nocivos ao meio ambiente. O biocombustível pode ser produzido através da reação de transesterificação ou esterificação de óleos vegetais ou gordura animal. Nesse sentido, o óleo residual de fritura se apresenta como uma alternativa de baixo custo e ambientalmente viável para ser utilizado como matéria-prima na produção do biodiesel. Porém a acidez elevada, característica dos óleos residuais de fritura (ORF), prejudica a síntese de biodiesel em apenas uma etapa reacional, encarecendo o processo. Dessa forma, faz-se necessário um pré-tratamento do óleo residual para que o mesmo seja utilizado na produção de biodiesel. O presente trabalho teve como objetivo utilizar o sabugo de milho como material adsorvente no tratamento do ORF, visando a diminuição do índice de acidez (IA) e possibilitando o seu uso na produção de biodiesel em etapa reacional única. As amostras de óleo utilizadas foram adquiridas a partir de diferentes fontes e divididas em dois lotes, denominados Lote A e B. Para o Lote A, o teste de adsorção foi realizado em uma coluna de adsorção, preenchida com o sabugo in natura, e as amostras de óleo passaram pelo tratamento na coluna até que se alcançasse um IA menor ou igual a 0,5%. Posteriormente, o óleo tratado foi utilizado na síntese de biodiesel, que foi produzido através da reação de transesterificação alcalina, atingindo um rendimento de teor de éster de 96,8%. Já o teste de adsorção para o Lote B ocorreu em um béquer com leve agitação. Foram separadas 6 amostras, todas com 50 mL de óleo, e submetidas a agitação constante durante diferentes tempos e temperaturas. Foi utilizada uma quantidade de 5 g do material adsorvente in natura em cada amostra. Foram testados ao total 3 tempos (20, 40 e 80 min) e 2 temperaturas (25 e 60ºC). Os melhores resultados na redução do IA foram obtidos nas amostras submetidas ao tempo de 40 min a 60ºC e 80 min a 60ºC, com uma redução de 21,3% e 28,8%, respectivamente.

Baseado no projeto de pesquisa de doutorado apresentado para ingresso no Programa de Pós-graduação em Geografia do Instituto de Estudos Socioambientais - IESA da Universidade Federal de Goiás - UFG, no ano de 2021, este artigo apresenta uma revisão bibliográfica. Investiga-se a produção e reprodução do espaço pelas práticas da atividade turística, do tipo religioso em Baependi-MG, Nova Trento-SC e Salvador-BA. Práticas essas, mediadas pelas tecnologias do ciberespaço. Busca-se compreender como as ações que envolvem a prática do turismo religioso nessas cidades impactam nas alterações rítmicas do cotidiano. Para tal, aprofundamentos em referenciais teóricos, pesquisa netnográfica e trabalhos de campo abarcando uma etnografia serão realizados. O texto aqui apresentado traz discussões teóricas com alguns apontamentos acerca da realidade empírica, uma vez que os trabalhos de campo estão em fase inicial, como também a realização de entrevistas e levantamento documental.

Point-of-care (POC) detection of herbicides is of great importance due to their impact on the environment and potential risks to human health. Here, we design a single-atomic site catalyst (SASC) with excellent peroxidase-like (POD-like) catalytic activity, which enhances the detection performance of corresponding lateral flow immunoassay (LFIA). The iron single-atomic site catalyst (Fe-SASC) is synthesized from hemin-doped ZIF-8, creating active sites that mimic the Fe active center coordination environment of natural enzyme and their functions. Due to its atomically dispersed iron active sites that result in maximum utilization of active metal atoms, the Fe-SASC exhibits superior POD-like activity, which has great potential to replace its natural counterparts. Also, the catalytic mechanism of Fe-SASC is systematically investigated. Utilizing its outstanding catalytic activity, the Fe-SASC is used as label to construct LFIA (Fe-SASC-LFIA) for herbicide detection. The 2,4-dichlorophenoxyacetic acid (2,4-D) is selected as a target here, since it is a commonly used herbicide as well as a biomarker for herbicide exposure evaluation. A linear detection range of 1-250 ng/mL with a low limit of detection (LOD) of 0.82 ng/mL has been achieved. Meanwhile, excellent specificity and selectivity towards 2,4-D have been obtained. The outstanding detection performance of the Fe-SASC-LFIA has also been demonstrated in the detection of human urine samples, indicating the practicability of this POC detection platform for analyzing the 2,4-D exposure level of a person. We believe this proposed Fe-SASC-LFIA has potential as a portable, rapid, and high-sensitive POC detection strategy for pesticide exposure evaluation.
Obreros comunistas, comunistas obreros:
Authors: Castells Carlos
Published: August 2022

A partir de 1930, el Partido Comunista Paraguayo (PCP), que por entonces estaba conformado por un pequeño número de propagandistas obreros, se propuso el objetivo de dirigir al movimiento obrero paraguayo. Para 1936 este objetivo se había alcanzado y los comunistas ocupaban un rol protagónico en la nueva Confederación Nacional de Trabajadores, liderazgo que con sus altibajos sostendrían durante una década para perderlo de manera abrupta y violenta luego de la sangrienta guerra civil de 1947. Este trabajo se propone analizar cómo se construyó la hegemonía comunista en el movimiento obrero y las características particulares que asumió la siempre conflictiva relación entre el partido y las organizaciones sindicales.
Hacia una renovada relación con el lenguaje: La idea de concepto en Ortega como puente entre la pura nominación y la enunciación dentro del habla Heideggeriana
Authors: Miranda Bascopé Christian
Published: August 2022

Este trabajo, intenta realizar un puente filosófico entre la concepción meramente instrumental del lenguaje y aquella concepción que entiende al habla desde un sentido mucho más esencial y originario. Desde las reflexiones filosóficas de Martin Heidegger y José Ortega y Gasset se propone un camino que permita generar una nueva relación con el lenguaje, y por ende con la comunicación en su sentido pleno. De esta forma, este trabajo intenta construir un enlace filosófico entre el lenguaje poético heideggeriano y un lenguaje instrumental construido a partir de éste, que incorpore el poder nominador del habla heideggeriana, pero que a la vez “descienda” ese poder ontológico a un nivel comunicativo. La idea orteguiana de “concepto”, servirá de base para construir este contacto y diálogo filosófico en torno al lenguaje.
Organización, discurso y actividad digital. Una aproximación al movimiento Antivacunas en grupos de WhatsApp
Authors: Peredo Rodríguez Valeria
Published: August 2022

En enero de 2022, Bolivia vivió protestas masivas protagonizadas por el movimiento antivacunas. En este artículo exploramos la dimensión tecnológica del conflicto, a través de una aproximación a grupos antivacunas en WhatsApp. Exploramos características generales de su organización, describimos elementos centrales en su discurso y nos aproximamos a las actividades que realizan dentro de los chats grupales. Asimismo, y en vista de que no existen muchas investigaciones sociales dentro de WhatsApp en Bolivia, este artículo también hace una propuesta metodológica, que combina la observación etnográfica con métodos digitales. Además, ensayamos posibles consideraciones éticas para la investigación dentro de la aplicación.
The tale of Tamīm b. ʿAmmār: a ninth-century Jew from the Hijaz
Authors: Mazuz Hagai
Published: August 2022

Haggai Mazuz’s article “The tale of Tamīm b. ʿAmmār: a ninth-century Jew from the Hijaz,” presents the reader with a Genizah manuscript containing the story of Tamīm b. ʿAmmār al-Ḥijāzī, a ninth-century Jew who lived in the Hijaz region of the Arabian Peninsula. The document tells about two meetings between Tamīm and the Abbasid caliph al-Maʾmūn (r. 786-833). Tamīm was in charge of the transfer of taxes from Egypt to the Caliph in the first third of the ninth century and commanded a force that secured convoys. This is a unique source for this story and it enriches our knowledge about the Jews of the Hijaz after the advent of Islam and the role they played in the Muslim world in the first centuries after the hijra. A transliteration of the document and its translation by Yaara Perlman is appended to the article.

Amnon of Mainz. The article includes an annotated edition of the piyyut.
The blessing of a Karaite and his excommunication: topics in the approach to Karaites in the writings of R. Abraham and his father Maimonides
Authors: Friedman Mordechai Akiva
Published: August 2022

The article by M.A. Friedman, `The blessing of a Karaite and his excommunication: topics in the approach to Karaites in the writings of R. Abraham and his father Maimonides,” opens with a previously unpublished halakhic responsum by R. Abraham Maimuni. This responsum deals with the saying of Amen after a Karaite blessed a circumcision and with the excommunicating of the Karaites as the Cuthites (Samaritans) had been excommunicated in the past. According to the author’s reading, R. Abraham Maimuni rules in his responsum that the Karaites should not be excommunicated “at this time” as the sectarians used to be excommunicated in the past. He demonstrates that in this ruling, R. Abraham Mainuni adopted his father’s approach in his Commentary on the Mishnah. Later, the author presents sources that indicate a moderate attitude of Maimonides and R. Abraham Maimuni towards the Karaites. His conclusion is that although he condemned the Karaite’s methods and imitating them, R. Abraham Maimuni believed that in their worship, and especially in their prayers, there were proper and good practices that were not contrary to the Torah and the words of the Sages and therefore the Rabbanites should imitate them.
“SYSTEM-ENVIRONMENT” INTERACTION IN THE LIGHT OF THE ANTHROPOCENTRIC PARADIGM OF LINGUISTICS
Authors: Mironova D.M.
Published: August 2022

The paper offers a systemological interpretation of the anthropocentric approach in linguistics from the point of view of its heuristicity in the analysis of feedbacks of a natural language with the environment. We emphasize ontologically conditioned connection of the language system with the conceptual one, which is the most important component of the environment for the language formation and functioning. Using the descriptive method, as well as the methods of conceptual, contextual, definitional and word-formation types of analysis, the work specifies the constitutive role of positive feedbacks that ensure the functioning of language as a means of cognition. The author considers some language phenomena illustrating the results of this type of connections in the representative side of the language, and also identifies the role of normative phenomena in the implementation of negative feedbacks that contribute to the communicative stability of the language system. It is concluded that the inclusion the relations of language with the environment in the linguistic research makes it possible to more fully characterize the flexibility of its system and explain qualitative changes focused on current cognitive tasks.
LEGAL TERMS IN THE TEXTS OF GENERAL TERMS AND CONDITIONS: TRANSLATION PROBLEMS (BASED ON TRANSLATION FROM GERMAN INTO RUSSIAN)
Authors: Tretiakova M.V.
Published: August 2022

This article discusses the features of the translation of legal terms from German into Russian in the texts of General Terms and Conditions. Such a document is the basis for the activities of most companies, which is why its adequate translation is so important for international business. The texts of General Terms and Conditions belong to the legal substyle of the official business style; the main linguistic features of such texts were identified. The problems of translating such texts arise due to the linguistic nature of the terms, to the specific characteristics of legal terms, to the discrepancy between the legal systems of states, and may also be associated with insufficient training of translators. The analysis revealed typical translation errors caused by reverse linguistic and cultural interference. Specialized terminology from other areas of knowledge, such as banking and freight traffic, was found challenging the translator's job. The material of the study consists of 50 texts of General Terms and Conditions, the total number of pages is 489.
