In many countries like Pakistan, where crops are irrigated by wastewater, the accumulation of heavy metals is a serious problem, especially when such an irrigation is a widespread practice. The focus of this study was to know the highly toxic metals like cadmium (Cd), chromium (Cr), and lead (Pb) in water, agricultural soil, and crops, besides their probable risk to human health in the area of Vehari district. The physicochemical parameters were determined for the samples, including organic matter, organic carbon, pH, and electrical conductivity. Water used for irrigation, samples of vegetables for Cd, Cr, and Pb concentration, as well as transfer factor from soil to plants (TF) were analyzed for calculating the daily intake of metals (DIM) and their health risk index (HRI). The results show that the wastewater used for irrigation was contaminated with Cr (0.07mg/kg), Cd (0.054mg/kg), and Pb (0.38mg/kg). In the tube well, the concentrations of heavy metals were: Cd (0.053mg/kg), Pb (0.01mg/kg), and Cd (0.03mg/kg). Application of wastewater increased heavy metals concentration in soil and vegetables. Heavy metals concentrations in wastewater irrigated soil before sowing vegetables in mg/kg were: Pb (0.91), Cd (0.12), and Cr (0.48). After the application of wastewater, significant enrichment of wastewater was observed in Pb (1.93mg/kg), Cd (0.07mg/kg), and Cr (0.34mg/kg). Our study showed a high-risk index of food crops polluted with heavy metals and resultantly greater health risk to humans and animals. That is why preventive measures should be adopted to reduce heavy metals pollution to irrigation water and soils to protect both humans and animals in the Vehari district.
The right to entrepreneurial expression over heritage significance: the micropolitics of an adapted cafe in a historic Chinese town

Published: October 2022

This study draws on Henri Lefebvre’s (The production of space, 1992, translated by D. Nicholson-Smith) concept of the spatial triad to examine the micropolitics of the production of urban and social space in a cafe in a historic tourist town in the southern Chinese city of Zhuhai. Such a spatial and social examination of the historic town of Tangjiawan’s Wangchuan Cafe is conducted in the context of a growing consumer society and experience economy in China. Specifically, we found that the cafe proprietor has performed a role that is commonly associated with official planners and technocrats in creating a ‘coffee art living space’ in a process that Lefebvre describes as a ‘representation of space,’ and that ‘spatial practices’ serve to shape the space away from the heritage significance of the town and towards entrepreneurially aligned ideals. Such resultant consumerist spaces are coconstructed with and negotiated by visitors and consumers. In conducting such an examination, we highlight and critique the ways in which dominant discourses operate in a microsite, such as that of a cafe, that has become a key cultural tourism attraction of the refurbished historic town, the means by which such discourses and visions result in real-world transformations and the ways in which visitors and tourists interpret and negotiate such a microsite.

PURPOSE

Patients with advanced pancreatic neuroendocrine tumors (NETs) have few treatment options that yield objective responses. Retrospective and small prospective studies suggest that capecitabine and temozolomide are associated with high response rates (RRs) and long progression-free survival (PFS).

PATIENTS AND METHODS

E2211 was a multicenter, randomized, phase II trial comparing temozolomide versus capecitabine/temozolomide in patients with advanced low-grade or intermediate-grade pancreatic NETs. Key eligibility criteria included progression within the preceding 12 months and no prior temozolomide, dimethyl-triazeno-imidazole-carboxamide or dacarbazine, capecitabine or fluorouracil. The primary end point was PFS; secondary endpoints were overall survival, RR, safety, and methylguanine methyltransferase (MGMT) by immunohistochemistry and promoter methylation.

RESULTS

A total of 144 patients were enrolled between April 2013 and March 2016 to temozolomide (n = 72) or capecitabine and temozolomide (n = 72); the primary analysis population included 133 eligible patients. At the scheduled interim analysis in January 2018, the median PFS was 14.4 months for temozolomide versus 22.7 months for capecitabine/temozolomide (hazard ratio = 0.58), which was sufficient to reject the null hypothesis for the primary end point (stratified log-rank P = .022). In the final analysis (May 2021), the median overall survival was 53.8 months for temozolomide and 58.7 months for capecitabine/temozolomide (hazard ratio = 0.82, P = .42). MGMT deficiency was associated with response.

CONCLUSION

The combination of capecitabine/temozolomide was associated with a significant improvement in PFS compared with temozolomide alone in patients with advanced pancreatic NETs. The median PFS and RR observed with capecitabine/temozolomide are the highest reported in a randomized study for pancreatic NETs. MGMT deficiency was associated with response, and although routine MGMT testing is not recommended, it can be considered for select patients in need of objective response (ClinicalTrials.gov identifier: NCT01824875 ).

We investigated the physical properties of ZrCuSiAs-type oxypnictide CeCrAsO polycrystals by electrical transport, magnetic and thermodynamic measurements below room temperature. No superconductivity is found down to the lowest temperature measured (1.8 K). A first-order magnetic transition is consistently observed at

. A Schottky anomaly is observed around 14 K and the ground-state doublet of Ce ions splits by 3.75 meV. It is suggested that the magnetic moments of Cr ions, which show long-range order above room temperature, reorient at

. Meanwhile the generated internal magnetic field induces a short-range antiferromagnetic order of Ce moments, serving as a good probe for demonstrating the interplay between Cr-3 d and Ce-4 f electrons and further investigating the magnetism of Cr ions.

Published: October 2022

The layered Sittampundi Anorthosite Complex is covered by mafic and ultramafic rocks including anorthosite, gabbro, pyroxenite and other igneous rocks. The ultramafic terrain has frequently undergone metamorphism. In the present study, laboratory spectral measurements were carried out from mafic, ultramafic and felsic rocks in the 350–2500 nm spectral range to characterise their diagnostic spectral features and for further utilisation for rock-type mapping. In 2016, the Sittampundi complex was covered by an AVIRIS-NG airborne survey jointly conducted by the Space Application Centre (SAC-ISRO) and Jet Propulsion Laboratory (NASA). The level-2 AVIRIS-NG data was obtained from SAC and used to interpret various rock types. ENVI 5.3 software was used for digital image processing of the AVIRIS-NG airborne hyperspectral data. The continuum-removed spectra of major rock types including anorthosite, meta-anorthosite, gabbro, meta-gabbro, pyroxenite, pegmatite, granite, gneiss and migmatite were critically analysed and their diagnostic absorption features correlated with chemistry and mineralogy. The AVIRIS-NG data analyses include bad band removal, minimum noise fraction transformation (MNF) and band combination. Out of various band combinations, the MNF composite images B456, B546 and B561 provided an enhanced output for the delineation of various rock types in the ultramafic terrain.

Jurisdição: uma função pública estatal de acesso à justiça
Authors: Costa Rosalina Moitta Pinto da , Moura João Vitor Mendonça de
Published: October 2022

O trabalho analisa a moderna tendência doutrinária que propõe o alargamento do conceito de jurisdição, desvinculando-a da atividade estatal, para abarcar outras formas de solução de conflito. Tendo como opção metodológica o método dedutivo, fundado na pesquisa bibliográfica, inicia-se com o estudo da ampliação do acesso à justiça. A seguir, analisam-se as diversas acepções de jurisdição, demonstrando a divergência doutrinária desde os conceitos clássicos até as modernas concepções que desvinculam a atividade jurisdicional da atividade estatal. Ao final, conclui-se que a jurisdição é uma atividade pública estatal de pacificação que sempre coexistiu com outras formas de solução de conflito.
A EXECUÇÃO DE DECISÕES COLETIVAS PELO MINISTÉRIO PÚBLICO: UMA QUESTÃO DE INTERESSE SOCIAL
Authors: Arenhart Sérgio Cruz , Osna Gustavo
Published: October 2022

O tema da tutela coletiva de direitos individuais, ao longo dos últimos anos, tem merecido especial atenção por parte de nossa teoria do processo civil. Nesse palco, insere-se um problema bastante particular: o regime e os critérios para a execução da decisão coletiva. O presente artigo enfrenta uma temática específica inserida nessa seara: a legitimidade do Ministério Público para efetivar a decisão coletiva. Nesse sentido, demonstra-se, primeiramente, como o Superior Tribunal de Justiça, apreciando o REsp 1801518/RJ, manifestou posição restritiva à atuação do Parquet. Na sequência, porém, argumenta-se que essa leitura não confere o melhor tratamento à matéria. Em resumo, além de limitar a efetividade do processo coletivo e de sujeitá-lo a uma insegura aferição casuística, o posicionamento desconsidera um ponto basilar: sempre que admissível, a proteção coletiva de direitos individuais possuirá, por si só, um relevante interesse social.

O presente artigo voltou-se ao tema das cortes de vértice em diferentes ordenamentos jurídicos e à avaliação crítica do Superior Tribunal de Justiça e do Supremo Tribunal Federal do Brasil. O objetivo central da pesquisa foi analisar as cortes de vértice brasileiras da justiça comum, ou seja, não especializada - Superior Tribunal de Justiça e do Supremo Tribunal Federal – à luz dos modelos de cortes de vértice de diferentes países. Para tanto, utilizou-se essencialmente de método de abordagem dedutivo tradicional, partindo-se de conceitos gerais a fim de depreender conclusões específicas. Como resultado, repisou-se conceitos essenciais às cortes de vértice e características de alguns modelos de cortes, permitindo-se observar que o sistema brasileiro possui similaridades com outros ordenamentos jurídicos e concluindo-se no sentido de que cada corte de vértice – à sua maneira – reflete a cultura jurídica local do seu próprio ordenamento jurídico face à clara intersecção do direito com a cultura.
Trajectories of liberalisation on the European industrial relations systems
Authors: Arribas Camara Javier , Cárdenas Luis
Published: October 2022

The main hypothesis of this article is that labour liberalisation in the post-Fordist period has affected the three principal areas of collective bargaining coordination (coverage, dominance and control) in two different ways: by attacking the core (deregulation) and the margins (dualisation) of industrial relations. Due to differences in the institutional structures of European countries, these processes could have different effects in each country, resulting in differentiated and gradual path-dependent transformations. This hypothesis is tested by studying the institutional frameworks of industrial relations in several representative European economies: France, Germany, Greece, Italy, Poland, Spain, Sweden and the United Kingdom. Finally, we conclude that there has been a substantial modification of the role, activity and weight of collective actors in the economic system of each country as a consequence of the effect of the different forms of liberalisation on the coordination of collective bargaining. As a corollary, a shift in European Union labour policies towards a further strengthening of collective bargaining spaces is needed to give social partners greater capacity to seek coordinated solutions to contemporary economic and social problems.
Workforce globalisation, language and discourse
Authors: Kuznetsov Andrei , Kuznetsova Olga , Fernández de Simón de la Cruz Jaime
Published: October 2022

The globalisation of the labour market creates new challenges for organisations when hiring. This article addresses one such challenge that is rarely in the spotlight: the implications of the choice of a language proficiency test for non-native speakers by the hiring organisation. We use the UK National Health Service (NHS) recruitment practices as an example. With the help of a staged experiment, this practice-based study argues that the current international recruitment procedure to the NHS tends to underestimate some important differences between language as a formalised system of words and grammatical rules and discourse as ‘language in action’, causing the loss of staffing capacity. It follows from our analysis that when setting the requirements and objectives of a language test, the recruiting organisations need to consider more explicitly the social and cultural context in which their employees operate and the impact of this context on the communication demands faced by the staff.

A laser-illuminated differential image motion monitor (DIMM) is presented that is able to measure the atmospheric coherence length

r

along horizontal ground paths. This is accomplished by implementing a mono-static setup in which the transmitter and receiver are co-located and transmit to a retroreflective target. The impact of propagating along a folded path through the same volume of turbulent atmosphere is investigated in detail and the overall impact to angle-of-arrival measurements described. In addition, an outdoor test campaign was conducted to validate the findings by testing two commercial scintillometers and the laser DIMM side by side in both bi-static and mono-static configurations. Both analytical and experimental results show that under certain conditions, folded-path propagation can be treated identically to traditional single-path propagation.
Optimal in-depth trapping by tuning the correction collar of a dry objective lens

Published: October 2022

Optical tweezers are proven and indispensable micro-manipulation tools.
It is very common to use an immersion-assisted high NA objective for
optical trapping of micrometer-sized beads. However, such objectives
suffer from low working depth range. Here we show, both by theory and
experiment, that a dry objective can be utilized for optimal trapping
of even sub-micrometer objects. For the first time, to the best of our
knowledge, we were able to stably trap polystyrene beads with radii of
270 and 175 nm in 3D using an objective with numerical aperture
of 0.9.
Ultra-broadband flat-top circular polarizer based on chiral fiber gratings near the dispersion turning point

Published: October 2022

Based on the dual-resonance principle around the dispersion turning point, a scheme of chiral long-period fiber gratings (CLPGs) formed by twisting a high-birefringence (Hi-Bi) fiber is herein proposed to realise ultra-broadband flat-top circular polarizers. The coupling bandwidth is approximately seven times larger than that of traditional CLPGs. In addition, by introducing chirp characteristics in these CLPGs, an ultra-broadband flat-top circular polarizer with ∼200 nm@3 dB was conveniently achieved. Subsequently, by optimising the chirped CLPGs, a circular polarizer with a bandwidth extinction ratio of approximately 30 dB and a high level of ∼100 nm at 1 dB was realised. It was shown that the mode-controlling performances of the CLPGs can be remarkably improved, which has significant applications in light-field regulation. Finally, for the first time, it was proved that the CLPG cannot generate a vortex beam.

Published: October 2022

In this paper, a carrier-injection electro-absorption modulator (EAM) at 2 µm is demonstrated on Ge-on-Si platform. The EAM shows a compact size and high modulation efficiency due to the strong free-carrier electroabsorption (FCEA) effect in Ge. A modulation depth of 40 dB can be obtained under the injection current of only 420 mA. Small-signal frequency response measurement is performed and a small-signal equivalent circuit model is proposed. Based on reflection coefficients and equivalent circuit, the frequency response of carrier-injection EAM is discussed in detail. The 500 Mbps open eye diagram verifies the data-processing capacity of our EAM at 2 µm wavelength for its application in biological, chemical molecular detection, and infrared imaging systems.
Switchable multi-functional broadband polarization converter in terahertz band
Authors: Zhang Xingrun , Zhang Kun , Chen Bingyu , Guo Lijun , Kong Weijin
Published: October 2022

In this work, we propose a multi-functional broadband terahertz polarization converter based on graphene-VO2 hybrid metamaterial, which can switch between transmissive linear-to-linear conversion and reflective linear-to-circular conversion. The function of the metamaterial can be controlled by both the temperature and the Fermi energy of the graphene. At 298K, the metamaterial converts the y-polarized wave into x-polarized wave in 0.39-1.22THz. In the meanwhile, changing the Fermi energy of graphene, the converted polarization angle can be tuned from 90° to 45°. Increasing the temperature to 358K, the incident linearly polarized wave is reflected into circularly polarized wave. On this condition, tuning the Fermi energy, the metamaterial can separately convert the linear polarization wave into left-circularly polarized wave in 1.57-2.74THz and right-circularly polarized wave in 1.13-1.59THz. Such a switchable multi-functional broadband polarization converter may achieve potential applications in compact terahertz devices and integrated terahertz circuits.
High power ytterbium rod-type fiber laser delivering tunable picosecond pulses
Authors: Ghawas Muhammad , Freysz Valerian , Müller Lukas , Cassagnère Sébastien , Freysz Eric
Published: October 2022

We designed an all-normal dispersion ytterbium rod-type fiber laser oscillator delivering picosecond pulses which are continuously tunable both in central wavelength and pulse duration. This system delivers self-mode-locked pulses with an average power up to 25 W. At a repetition rate of 78 MHz, it yields picosecond laser pulses, of which the central wavelength and pulse duration can be tuned between 1010 nm - 1060 nm and 4.5 ps - 1.8 ps, respectively. The tunability is obtained by adjusting the position and the width of a slit which acts as a spectral bandwidth filter, placed close to the center of a 4f-folded zero dispersion line inserted in the laser cavity. This oscillator delivers nearly Fourier limited pulses with at most a 1.2 time-bandwidth product. A numerical model accounts well for the behavior of this all-normal dispersion fiber oscillator.
Generating different polarized multiple Fano resonances for highly sensitive sensing using hybrid graphene–dielectric metasurfaces
Authors: Li Changhong , Yang Rui
Published: October 2022

We demonstrate the perfect generation of four Fano resonances with different polarizations in the mid-infrared regime through a hybrid graphene–dielectric metasurface consisting of three pieces of silicon embedded with graphene sheets over the CaF2 substrate. Through monitoring the variations of polarization extinction ratio of the transmitting fields, a tiny difference of analyte refractive index can readily be detected from the drastic changes at Fano resonant frequencies in both co- and cross-linearly polarized components. Especially, the reconfigurable characteristic of graphene would be capable of tuning the detecting spectrum by pairwise regulating the four resonances. The proposed design should pave the way for more advanced bio-chemical sensing and environmental monitoring using metadevices with different polarized Fano resonances.

The COVID-19 pandemic has caused widespread illness with varying clinical manifestations. One less-commonly-reported presentation of COVID-19 infection is chilblain-like lesions. We conducted an ecological analysis of chilblain presentations in comparison with confirmed and suspected COVID-19 infections in a primary care setting to establish that a relationship exists between the two. Our study collated data from three Primary Health Networks across Victoria, Australia, from 2017–2021, to understand patterns of chilblain presentations prior to and throughout the pandemic. Using a zero-inflated negative binomial regression analysis, we estimated the relationship between local minimum temperature, COVID-19 infections and the frequency of chilblain presentations. We found a 5.72 risk ratio of chilblain incidence in relation to COVID-19 infections and a 3.23 risk ratio associated with suspected COVID-19 infections. COVID-19 infections were also more strongly associated with chilblain presentations in 0-16-year-olds throughout the pandemic in Victoria. Our study statistically suggests that chilblains are significantly associated with COVID-19 infections in a primary care setting. This has major implications for clinicians aiming to diagnose COVID-19 infections or determine the cause of a presentation of chilblains. Additionally, we demonstrate the utility of large-scale primary care data in identifying an uncommon manifestation of COVID-19 infections, which will be significantly beneficial to treating physicians.
Maternal mental health and child nutritional status in an urban slum in Bangladesh: A cross-sectional study
Authors: Khan Ahad Mahmud
Published: October 2022

Poor mental health may diminish a mother’s capacity to adequately care for her child, resulting in a negative impact on the child’s nutrition. This study aims to determine the association between maternal mental health and child nutritional status in a poor urban population in Bangladesh. We carried out a cross-sectional study among 264 mother-child pairs in an urban slum area of Bangladesh. The Self-Reporting Questionnaire-20 (SRQ-20) was used to assess maternal mental health. An SRQ-20 score ≥7 was considered a common mental disorder (CMD). Anthropometric measurements were performed to assess nutritional status of the children. The prevalence of maternal CMD was 46.2%. Maternal CMD was associated with poorer child feeding practice (p<0.001), poorer hygiene practice (p<0.001), poorer preventive care service use (p = 0.016), and suffering from diarrheal diseases (p = 0.049). The prevalence of stunting, wasting and underweight in children was 44.3%, 18.2% and 33.7%, respectively. A poorer child feeding practice was associated with wasting (p = 0.004) and underweight (p<0.001) but not with stunting. Poorer hygiene practices and suffering from diarrheal diseases were associated with stunting and underweight, but not with wasting. In multivariable analysis, maternal CMD was associated with child wasting (adjusted odds ratio, aOR = 2.25, 95% CI = 1.15–4.43). The association between maternal CMD and child underweight found in the bivariate analysis was attenuated and no longer statistically significant after multivariable analysis (aOR = 1.77, 95% CI = 0.94–3.33). No statistically significant association was observed between maternal CMD and stunting in this study (aOR = 1.46, 95% CI = 0.84–2.54). Maternal mental health affects nutritional status of the children where child feeding practice, hygiene practice and preventive care use might play a role. Interventions to address maternal mental health in child nutrition programs might improve child nutritional status.

Stigma is a critical barrier for TB care delivery; yet data on stigma reduction interventions is limited. This review maps the available literature on TB stigma reduction interventions, using the Health Stigma and Discrimination framework and an implementation analysis to identify research gaps and inform intervention design. Using search terms for TB and stigma, we systematically searched PubMed, EMBASE and Web of Science. Two independent reviewers screened all abstracts, full-texts, extracted data, conducted a quality assessment, and assessed implementation. Results were categorized by socio-ecological level, then sub-categorized by the stigma driver or manifestation targeted. After screening 1865 articles, we extracted data from nine. Three studies were implemented at the individual and interpersonal level using a combination of TB clubs and interpersonal support to target internal and anticipated stigma among persons with TB. Two studies were implemented at the interpersonal level using counselling or a video based informational tool delivered to households to reduce stigma drivers and manifestations. Three studies were implemented at the organizational level, targeting drivers of stigma among healthcare workers (HW) and enacted stigma among HWs. One study was implemented at the community level using an educational campaign for community members. Stakeholder consultation emphasized the importance of policy level interventions and education on the universality of risk to destigmatize TB. Review findings suggest that internal and anticipated TB stigma may be addressed effectively with interventions targeted towards individuals using counselling or support groups. In contrast, enacted TB stigma may be better addressed with information-based interventions implemented at the organizational or community level. Policy level interventions were absent but identified as critical by stakeholders. Implementation barriers included the lack of high-quality training and integration with mental health services. Three key gaps must be addressed in future research: consistent stigma definitions, standardized stigma measurement, and measurement of implementation outcomes.
Vivaria calvasensis—A new genus and species of Araceae (Araceae: Aroidea: Spathicarpeae) from southern Ecuador

Published: October 2022

We describe a new genus with a new species belonging to Araceae, from southern Ecuador.Vivaria calvasensis gen.et sp.nov. inhabits semi-arid inter- Andean mountains at altitudes ranging between 1100–1300 m a.s.l. The species belongs to the tribe Spathicarpae, which in Ecuador is represented by two other genera,IncarumandCroatellia, both typical for humid environments such as montane forests. This new genus is clearly supported by molecular evidence based on thematKgene, and morphological traits that separate it from the closely-related genera included in this tribe. The analyzed material was collected during several field campaigns carried out during four years in two populations from Loja province (Calvas and Macará), southern Ecuador, near the border with Peru.

Color morphs in ball pythons (Python regius) provide a unique and largely untapped resource for understanding the genetics of coloration in reptiles. Here we use a community-science approach to investigate the genetics of three color morphs affecting production of the pigment melanin. These morphs—Albino, Lavender Albino, and Ultramel—show a loss of melanin in the skin and eyes, ranging from severe (Albino) to moderate (Lavender Albino) to mild (Ultramel). To identify genetic variants causing each morph, we recruited shed skins of pet ball pythons via social media, extracted DNA from the skins, and searched for putative loss-of-function variants in homologs of genes controlling melanin production in other vertebrates. We report that the Albino morph is associated with missense and non-coding variants in the geneTYR. The Lavender Albino morph is associated with a deletion in the geneOCA2. The Ultramel morph is associated with a missense variant and a putative deletion in the geneTYRP1. Our study is one of the first to identify genetic variants associated with color morphs in ball pythons and shows that pet samples recruited from the community can provide a resource for genetic studies in this species.
Extending green supply chain practices through automation: Multinational best practices
Authors: Weeks Kelly , Montabon Frank , Kenyon George
Published: October 2022

This study simultaneously investigates the effect ‘greening’ has on supply chains and the effect injecting automation has upon these green supply chains. This article adapts the natural resource-based view of the firm, a theoretical perspective prevalent in management literature, to develop a conceptual framework. This study surveys 292 firms from multiple countries to test both relationships. Literature has laid the initial groundwork for multinational manufacturing efficiency studies that we build and expand upon. Multiple techniques were used to mitigate common method bias, including multiple survey responses per firm sampled, confirmatory factor analysis with Chi- square and Harman’s test of common method bias. We find automation generally lends itself to improving aspects of green supply chains regardless of global location of firms. With increasing automation levels, supply chain efficiency improves, thereby improving economic performance. Once automation is employed, there’s a positive effect that cascades through the entire supply chain.
Food independence and efficient exploitation of natural resources
Authors: Bouchakour Radhia , Bersali Mohamed Nabil
Published: October 2022

We examine the efficiency of 113 countries in exploiting their natural resources to achieve food independence. Our results suggest that food independence is determined by natural resources endowments, and research and development. Per-capita agricultural land, renewable freshwater and irrigation increase food independence, whereas temperature rise and storm severity have the reverse effect. Food independence efficiency is promoted by the presence of strong legal rights and infrastructure, but inhibited by population growth, agriculture volatility and oil rents. Our findings also suggest that oil-producing countries are the least efficient, but contrary to expectations, low-income economies are more efficient than industrialized economies.

Published: October 2022

En la sociedad contemporánea la poscustodialidad propone a las bibliotecas, archivos y museos una Curación Digital de narrativas sociales heterogéneas y de voces polisémicas. Sin embargo, el proceso curatorial existente no es claro en lo que respecta a la participación de los sujetos y de las comunidades de interés en las acciones de curación. En ese sentido, re lexionamos sobre si el Modelo de Curación Digital presentado por Higgins (2008) satisface la necesidad poscustodial de la sociedad postmoderna y proponemos que existan otras facetas de la Curación Digital que propicien la apertura de las instituciones museológicas a los sujetos y a las comunidades de interés y los conviertan en productores de contenidos culturales que puedan ser curados. Para ello, se presentan las acciones y procesos del Modelo de Curación Digital de Higgins (2008) y se exploran las posibilidades de Curaciones Colectiva y Social que incluyen a las comunidades de interés en los procesos curatoriales, de forma participativa, en la construcción de una narrativa transcultural.

Published: October 2022

This article presents the integral antioxidant activity (IAA) data of extracts based on the fruits of
mountain ash (Sorbus aucuparia) obtained by coulometric titration with electrogenerated bromine
and DPPH-test. A good agreement of the results confirmed the high antioxidant and antiradical activity
of the studied phytoextracts. The influence of heat treatment method on the studied indicator was also
estimated. The prospects and expediency of using the method of galvanostatic coulometry for
determining the integral antioxidant activity of phytoextracts of Rowan fruits (Sorbus aucuparia)
have been established.
