AbstractThe reduction of azo dyes to less toxic and more easily biodegradable amine derivatives is an effective strategy for the treatment of industrial wastewater. The present work aimed to study the reduction reaction of azo dye Congo red (CR) catalyzed by nanoparticles (NPs) of chromium oxides (Cr2O3NPs) immobilized on bentonite in the presence of NaBH4. Cr(III) ions were intercalated using ion exchange reactions to obtain Cr-bentonite, and then the immobilized chromium cations were treated using NaBH4 leading to the formation of Cr2O3NPs-bentonite. The physicochemical properties of the samples were investigated using X-ray diffraction (XRD), scanning electron microscopy/energy dispersive spectroscopy (SEM-EDS), atomic absorption spectrometry (AAS), UV–Visible diffuse reflectance (UV–Vis DR), and Fourier-transform infrared (FTIR) spectroscopy techniques. The results showed the formation of various chromium species, in which the most dominant were chromium oxide nanoparticles, on the bentonite surface with an average particle size between 20 and 35 nm. Line-scan analysis showed a reactive catalytic surface due to the excellent distribution of Cr on the bentonite surfaces. The best-performing catalyst, Cr2O3NPs-bentonite, displayed significant catalytic activity compared to the bentonite and Cr-bentonite materials, with a full reduction time of 630 s and a rate constant, kapp, equal to 0.034 s–1. The resulting products (benzidine and sodium 3, 4-diaminonaphthalene-1-sulfonate) from the catalytic reduction exhibited low toxicity compared to the CR dye; these products are easy to use in chemical synthesis. All results collected from this work indicated that this low-cost catalyst can be exploited to eliminate other dyes from the environment.
BHR Agenda and Authoritarian Regimes: The Case of Political and Human Rights Crisis in Belarus Since 2020
Authors: Deikalo Ekaterina 
Published: April 2023

AbstractThis article aims to highlight peculiarities relating to the realization of the state duty to protect human rights during the crisis situation after the 2020 presidential elections in Belarus. It proposes that we engage more seriously with the context of a strong authoritarian state, which does not have people’s protection as a priority and deliberately involves business in human rights violations. Such a context is at odds with the more often presumed model in the BHR discussion: a strong business and a weak state that cannot protect its people. Two systemic factors, which stem from the authoritarian nature of the Belarusian political regime and which worsened during the crisis are discussed in the context UN Guiding Principles on Business and Human Rights: the use of business as a tool to achieve political goals and the dependence of all institutions in the country on the authorities. One of the key conclusions of the article is that the Belarusian crisis, aggravated by the complicity of Belarus in the Russian aggression, prompts businesses to adopt a new optic on human rights due diligence and to assess their long-term risks and strategies in authoritarian countries. At the very least there is an awareness among businesses of the direct link between political and human rights risks.
Addressing health disparities in the criminal legal system: Translational benefits, challenges, and facilitators of impactful research with incarcerated pregnant women
Authors: Volkov Boris B. , Pulley Chris , Shlafer Rebecca 
Published: April 2023

AbstractThis in-depth analysis illuminates a translational journey of a community-university research collaboration that examined health disparities among incarcerated pregnant women and spanned the translational spectrum, with the initial collaboration in 2011 paving the way for consequent research grants, publications, practices, programs, and legislation passed years later. The case study utilized data from interviews with research stakeholders, institutional and governmental sources, peer-reviewed publications, and news stories. Identified research and translational challenges included cultural differences between research and prison system; the prison system’s lack of transparency; politics of using and translating research to policy change; and issues of capacity, power, privilege, and opportunity when doing community-engaged research/science. Among the facilitators of translation were the Clinical and Translational Science Award and institutional support; engagement of key stakeholders and influencers; authentic collaboration and team science; researchers as translation catalysts; pragmatic scientific approach; and policies and legislative activities. The research contributed to a variety of community and public health, policy/legislative, clinical/medical, and economic benefits. The case study findings enhance our understanding of translational science principles and processes leading to improved wellbeing and serve as a call for advancing the research agenda addressing health disparities related to criminal and social justice issues.
Community-engaged training in informed consent

Published: April 2023

AbstractInadequate training in the interpersonal skills of conducting informed consent conversations has long been noted as a challenge for clinical research recruitment and retention. To address this critical gap, Tufts Clinical and Translational Science Institute developed regular trainings for clinical research coordinators and other research staff on the practical skills of communicating informed consent using community members as simulated patients for role-playing exercises. In this paper, we assess the reach and effectiveness of these trainings and describe the impact of employing community stakeholders as simulated patients. We found that by embedding community members in the trainings, clinical research coordinators get to hear diverse perspectives, experience a range of patient responses, and learn from the lived experience of the communities that research tries to serve. Utilizing community members as trainers also helps to dismantle traditional power dynamics by demonstrating the organization’s commitment to inclusiveness and community engagement. Based on these findings, we suggest that training on informed consent include more simulated consent exercises that feature interaction with community members who can provide real-time feedback to coordinators.
Disputing death: brain death in the courts
Authors: Donnelly Mary , Lyons Barry 
Published: April 2023

AbstractDeath by neurological criteria (DNC) has remained controversial since its introduction over 50 years ago. Objections to the diagnosis of DNC have been coming before the courts in various jurisdictions, including at least seven recent challenges before the UK courts. In responding to these challenges, the UK courts have expressed no doubts as to the status of DNC and have affirmed that following a diagnosis of DNC, the matter of best interests is no longer relevant. Yet, the courts have also, tacitly, acknowledged that DNC is not quite the same as cardio-pulmonary death.This paper begins by setting out the origins of DNC as a medico-legal construction, and its ongoing controversies. It then analyses the treatment of DNC, including authorisation of DNC testing, by the UK courts. It shows that the courts have been operating a form of ad hoc reasonable accommodation of different views of DNC but have done so without normative engagement. The paper argues that the courts should recognise that DNC disputes are not simply concerned with whether, as a matter of fact, DNC has been correctly diagnosed, but also raise profound questions about rights and interests, both of families and of the DNC dead.
Investing in Infants: Child Protection and Nationalism in Transylvania during Dualism and the Interwar Period
Authors: Gál Edina 
Published: April 2023

AbstractThe high infant mortality rate of illegitimate children in Dualist Hungary urged politicians to create a modern state child welfare system for the protection of abandoned children whose upbringing became a national matter. Their main concern was providing adequate nutrition for infants and increase their chances of survival. The article examines how demographical concerns and national-political ideals influenced the evolution of the child welfare system in multi-ethnic Transylvania, first as part of the dual monarchy and after the First World War as a province of Romania. The Hungarian state children’s asylums offered a variety of nursing programs for abandoned infants, where the foster-care system often resulted in their Magyarization at a later age. During the First World War, the new objective was the protection of infants together with mothers and the promotion of breastfeeding in order to ensure the viability of the Hungarian nation. National arguments were used in both time periods to support infant protection initiatives. In interwar Transylvania, the urban-rural ethnic distribution influenced the development of infant protection facilities: all state investments were channeled toward the “authentic” Romanian countryside, while in the “foreign” urban environment ethnic minorities focused on their own institutions.

Published: April 2023

AbstractLet G be a p-group for some prime p. Recall that the Hughes subgroup of G is the subgroup generated by all of the elements of G with order not equal to p. In this paper, we prove that if the Hughes subgroup of G is cyclic, then G has exponent p or is cyclic or is dihedral. We also prove that if the Hughes subgroup of G is generalised quaternion, then G must be generalised quaternion. With these results in hand, we classify the tidy p-groups.

Published: April 2023

AbstractBy defining and applying the restricted topology, we have investigated certain connections between the boundary spectrum, the exponential spectrum, the topological boundary of the spectrum and the connected hull of the spectrum (see Mouton and Harte [‘Linking the boundary and exponential spectra via the restricted topology’, J. Math. Anal. Appl.454 (2017), 730–745]). We now solve a remaining problem regarding the restricted connected hull.

AbstractSnowmelt spring floods regulate carbon transport from land to streams. However, these coupled processes are rarely documented through high‐resolution measurements focused on water‐carbon interactions. We collated a state‐of‐the‐art high‐frequency data set throughout a snowmelt and early post snowmelt period, alongside regular samples of stream water, precipitation, and snowmelt isotopes (δ18O). Our study was conducted during the 2019 snowmelt and initial post snowmelt season in a subarctic, peatland influenced headwater catchment in Pallas, Northern Finland. We measured high‐frequency dissolved organic carbon (DOC), and in‐stream carbon dioxide (pCO2). We identified a change in hydrological processes as the snowmelt season progressed and the post snowmelt season began. We found (a) Overland flow dominated stream DOC dynamics in early snowmelt, while increased catchment connectivity opened new distal pathways in the later snowmelt period; (b) CO2 processes were initially driven by rapid bursts of CO2 from the meltwaters in snowmelt, followed by dilution and source limitation emerging post snowmelt as deep soil pathways replaced the snowpack as the main source of CO2; (c) stream carbon concentration shifted from being relatively balanced between CO2 and DOC during the early snowmelt period to being increasingly DOC dominated as snowmelt progressed due to changes in DOC and CO2 source supply. The study highlights the importance of using high‐frequency measurements combined with high‐frequency data analyses to identify changes in the processes driving water‐carbon interactions. The degree to which water‐carbon interactions respond to the continuation of Arctic water cycle amplification is central to delineating the evolving complexity of the future Arctic.

Published: April 2023

AbstractHippocampal abnormalities are an established finding in the neuroimaging study of schizophrenia. However, no studies have examined the possibility of regional hippocampal abnormalities specific to deficit schizophrenia (DS) and associations with the unique symptoms of this schizophrenia subtype. This study compared 33 DS and 39 non-deficit schizophrenia (NDS) patients and 38 healthy subjects for hippocampal subfield volumetry. Clinical symptoms were assessed by PANSS, cognition by the neurocognitive battery on the day of the MRI scan. The automatic hippocampal segmentation were preprocesses use FreeSurfer 7.2.0. Unfortunately, the associations between neurocognitive scores and hippocampal subfield volumes in the DS group were not significant after the Bonferroni correction. Our results did not support a causal relationship between hippocampal subregional atrophy and cognitive deficits in DS.
Sensitivity of stratospheric ozone to the latitude, season, and halogen content of a contemporary explosive volcanic eruption

Published: April 2023

AbstractWe present a systematic evaluation of the perturbation to the stratosphere from an explosive volcanic eruption injecting sulfur dioxide into the atmosphere, as a function of latitude, season, and injection gas halogen content in a chemistry-climate state representative of the present day (modeled as year 2025). Enhancements in aerosol surface area density and decreases in stratospheric ozone are observed for a period of years following all modeled scenarios, with volcanic eruptions near the equator impacting both hemispheres relatively equally, and eruptions at higher latitudes reducing the thickness of the ozone layer more substantially in the hemisphere of the eruption. Our simulations reveal that there that are significant seasonal differences when comparing the stratospheric impact of a volcanic eruption occurring in summer versus winter, and this holds true regardless of whether volcanic halogen gases (Cl, Br) are co-injected with sulfur dioxide. If an explosive halogen-rich eruption were to occur, there would be substantial ozone losses in both hemispheres, regardless of latitude or season, with recovery potentially exceeding 4 years.
Mixed state behavior of Hermitian and non-Hermitian topological models with extended couplings
Authors: Kartik Y. R. , Sarkar Sujit 
Published: April 2023

AbstractGeometric phase is an important tool to define the topology of the Hermitian and non-Hermitian systems. Besides, the range of coupling plays an important role in realizing higher topological indices and transition among them. With a motivation to understand the geometric phases for mixed states, we discuss finite temperature analysis of Hermitian and non-Hermitian topological models with extended range of couplings. To understand the geometric phases for the mixed states, we use Uhlmann phase and discuss the merit-limitation with respect extended range couplings. We extend the finite temperature analysis to non-Hermitian models and define topological invariant for different ranges of coupling. We include the non-Hermitian skin effect, and provide the derivation of topological invariant in the generalized Brillouin zone and their mixed state behavior also. We also adopt mixed geometric phases through interferometric approach, and discuss the geometric phases of extended-range (Hermitian and non-Hermitian) models at finite temperature.
Accurate measurements of particle emissions from a three-dimensional printer using a chamber test with a mixer-installed sampling system

Published: April 2023

AbstractRecently, three-dimensional (3D) printing has attracted attention as a new manufacturing technology. However, there is lack of data and regulations regarding the emissions of ultrafine particles from 3D printers. Therefore, we investigated particle emissions from a 3D printer using a chamber system. The test system was improved by installing a developed mixer for accurate measurement. Without a mixer, the particle concentration was unstable depending on the sampling point; however, reliable data with good uniformity were obtained by installing a mixer. Using the test system with a mixer, we investigated particle emissions from a 3D printer during operation. Filaments made each of acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) were used as the printing material. The effects of nozzle temperature and printing time were investigated. Compared to the effect of the printing time, the nozzle temperature had greater impact on the particle emissions. The dominant particle size for the emissions from a 3D printer is less than 10 nm, and the particle concentration decreased with increasing particle size.
Differential regulation of ATP hydrolysis of RIG-I-like receptors by transactivation response RNA-binding protein

Published: April 2023

AbstractRetinoic acid inducible gene (RIG)-I-like receptors (RLRs), including RIG-I, melanoma differentiation associated-5 (MDA5), and laboratory of genetics and physiology 2 (LGP2), play pivotal roles in viral RNA sensing to initiate antiviral interferon (IFN) responses.We previously reported that an RNA-silencing regulator, transactivation response RNA-binding protein (TRBP), up-regulates MDA5/LGP2-mediated IFN responses through interaction with LGP2. Here, we aimed to investigate the mechanism underlying the TRBP-mediated up-regulation of IFN response.Data indicated that phosphomimetic TRBP showed a modest effect, whereas the nonphosphorylated form exhibited hyperactivity in enhancing Cardiovirus-triggered IFN responses. These results suggest that encephalomyocarditis virus (EMCV) attenuates the TRBP-mediated IFN response via TRBP phosphorylation, since EMCV infection activates the kinase responsible for TRBP phosphorylation for virus replication.Furthermore, we found that TRBP-mediated up-regulation of IFN response required the ATP hydrolysis and RNA binding of LGP2. TRBP enhanced RNA-dependent ATP hydrolysis by LGP2 but not that by RIG-I or MDA5. Nonphosphorylated TRBP exhibited higher levels of activity than phosphomimetic TRBP did, suggesting its possible involvement in the mechanism underlying the up-regulation of IFN response. TRBP activated the ATP hydrolysis of LGP2 and RIG-I, but not that of MDA5, in the absence of RNA. Collectively, we showed that TRBP differentially regulated RLR-mediated ATP hydrolysis. Further elucidation of the mechanism underlying the regulation of ATP hydrolysis leading to IFN response and self- and non-self-RNA discrimination could advance the development of effective therapeutic agents against autoimmune diseases.

Purpose:This study investigated to what extent residual hearing and rehabilitation options (e.g., hearing aids [HAs]) affect the auditory cortex in children with hearing loss.Method:Twenty-one children with bilateral congenital sensorineural hearing loss who were candidates for cochlear implantation were recruited. Voxel-based morphometry analysis was conducted to assess the gray matter (GM) volume in the auditory cortex. Children's residual hearing was measured by pure-tone audiometry at different frequencies. Multiple linear regression models were conducted to examine the effects of residual hearing and the use of HAs on GM volume in the auditory cortex with the control of age and gender.Results:Children with more residual hearing at high frequencies had larger GM volume ratio (corrected by total intracranial volume) in the left Heschl's gyrus (r= −.545,p= .013). An interaction effect between residual hearing and the use of HAs suggested that the effect of residual hearing on GM ratio was moderated by the use of HAs (β = −.791,p= .020). Compared with children with less residual hearing, children who had more residual hearing benefited more from longer use of HAs in terms of a larger GM ratio.Conclusions:Our preliminary findings highlight the impact of residual hearing on the neuroanatomy of the auditory cortex in children with hearing loss. Moreover, our results call for more auditory input via HAs for children with more residual hearing to preserve the auditory cortex before cochlear implantation. For children with less residual hearing who might receive limited benefit from HAs, an early cochlear implant would be necessary.
