Authors: Dr. Ankur Tripathi  , Nabarun Roy
Published: November 2023

A study was conducted during the year 2022–2023 for in silico analysis of two Vigna linearis lectins in the computer lab, CDFT, Jodhpur, Rajasthan, India. Amino acid sequences of both lectins were obtained from NCBI database and analyzed using different computational tools. Primary structure analysis using ProtParam server revealed acidic, stable and hydrophobic nature of both VLL proteins. Both proteins were predicted heavily glycosylated with a single signal peptide cleavage site (A26-A27). High sequence similarity of both VLL proteins was observed with adzuki, rice bean and moth bean lectins. Both VLL proteins had high proportions of β-sheets in their secondary structure. Good quality 3D structures for both VLL proteins were modelled using Modeller software. A Jelly roll fold, also known as β-sandwich structure was identified in the 3D structure of both VLL proteins. Profunc server annotated both lectins as a carbohydrate binding regulatory protein with significant role in plant defense (GO terms: 0065007, 0006952, 0050896, 0006950, 0009607, 0030246). Galaxy Site web server predicted galactose, A2G (2-acetamido-2-deoxy-α-D-galactopyranose), MFU (Methyl α-L-fucopyranoside) and adenine as common binding ligands for both VLL proteins. Lig Plot analysis revealed hydrogen bonding and hydrophobic interactions were the major bonding interactions between VLL proteins and putative ligands. The results of the study would provide a base for conducting future research on Vigna linearis lectins for different applications.
Study on the Consumers’ Satisfaction Extension for Self-service Technology and the Role of Demographic Characteristics in Hong Kong Fast-food Restaurants During the COVID-19 Epidemic
Authors: Mo Wing Ying , Xu Xiaofen
Published: November 2023

This study explores the effects of perceived ease of use, perceived usefulness, service speed, and perceived enjoyment on experience satisfaction and experience extension when Hong Kong fast-food restaurant consumers use self-service technology and the impact of different consumer characteristics on the degree of different experience satisfaction. Using a mixed research method, combining qualitative and quantitative methods, using focus groups and literature discussions as the collection of qualitative data, using interview questionnaires and large-scale questionnaires as the collection of quantitative data. Moreover, recovering effective data by snowballing is one of the non-probability methods. There are 315 questionnaires in total. Using the SPSS system to analyze the collected data, the results show that all factors are essential, and the relationship between each group of variables is positively correlated. Age, gender, and education level of consumer characteristics all have significant differences in experience satisfaction, while income and marital status have no significant differences in experience satisfaction. It is recommended that policymakers, technology providers, and industry work together to improve existing technologies and allow seniors to have a more inclusive experience, reduce the gap in experience satisfaction among consumers with different educational levels, and increase the satisfaction of the self-service experience of consumers with lower education levels.

Published: November 2023

Poorly organized training schedules that are not focused on optimizing the cardiopulmonary fitness of the runner may lead to negative outcomes in their performance. Further, reduced cardiopulmonary fitness of a distance runner may lead to an imbalance of sympathetic and parasympathetic inputs of cardiac autonomic regulation. This altered balance of the regulation of the heart may recur as a vicious cycle, further hampering the runner's performance. The study assessed the effects of specialized training programs on the remodeling of cardiac autonomic regulation in relation to improving cardiopulmonary fitness and running performance of Sri Lankan male distance runners (N = 22). Before the intervention, runners were found to have more sympathetic dominancy on cardiac autonomic regulation along with suboptimal cardiopulmonary fitness level and suboptimal performance. After the intervention, more parasympathetic dominancy in cardiac autonomic regulation and improved cardiopulmonary fitness parameters were achieved. Post-intervention race timing of long-distance runners was significantly improved (p < 0.05) compared to the pre-intervention race timing irrespective of lower VO2peak level. The specialized training program used in this study optimized the parasympathetic dominancy of the autonomic regulation of the cardiovascular system of the Sri Lankan national long-distance runners. The runners were able to record significantly improved race timing after the specialized training intervention even though their VO2peak level was dropped. Thus, it is concluded that achieving parasympathetic dominant cardiac autonomic regulation is a better indicator than achieving higher VO2max levels given the performance of distance runners.

Published: November 2023

El presente texto busca caracterizar los modos de encuadre de la realidad comunicativa latinoamericana en la investigación doctoral sobre comunicación que se desarrolla en universidades españolas. Para ello, el trabajo recurrió a la localización, identificación y análisis de contenido de 358 tesis doctorales defendidas en el campo académico universitario de España entre 2007 y 2018, que estudiaron la realidad comunicativa latinoamericana. Además, se llevaron a cabo cuatro entrevistas semiestructuradas en dos rondas consecutivas mediante Delphi, con expertos latinoamericanos del campo académico para la triangulación de resultados y la discusión sobre los horizontes de la investigación doctoral sobre Latinoamérica en España. En consecuencia, se ha identificado un predominio de la investigación descriptiva, centrada además en el periodismo como ámbito de conocimiento, con una focalización intensa sobre la realidad comunicativa de solo unos pocos países. Asimismo, se evidencia la naturaleza contingencial de la investigación doctoral en el campo de conocimiento, en función de las modas o coyunturas académicas, con déficits importantes en la planificación de las políticas científicas, en las guías de las asignaturas universitarias de teorías y métodos de investigación y en la autorreflexión sobre los compromisos de transformación social del área disciplinar.

Inviting Small Children to Dialogue – Scaffolding and Challenging Conversational Skills
Authors: Bruce Barbro
Published: November 2023

The purpose of this study was to learn about how to scaffold and challenge conversational skills in children at an early stage in language development. Language production most often mirrors verbal comprehension, and moreover gives cues to the conversational partner to relate to and further expand upon. The presented results come from dialogues between speech and language therapists and children aged five to six whose language development has been found to be delayed for their age. However, the results are highly applicable to all children, particularly in small children during their most intensive language developing phases. The theoretical framework highlights the importance of being an active language learner, i.e. language skills are mastered by being used in social interaction. Twenty-two dialogues were video-, and audio recorded, transcribed and coded with respect to language structure and interaction. The mean number of words per turn in the children’s contributions was quantified and a qualitative analysis of the preceding turn of the elicitation strategies was performed. The results underline the importance of relating to the child’s focus without being soliciting, i.e. to comment and give feedback, rather than using many questions and imperatives.

Published: November 2023

This article describes how the process of writing a fictional narrative, “My Story”, transforms and emerges over a period of five days in a Swedish early childhood classroom. Our purpose is to explore and describe how this method-driven writing project emerge in relation to material and discursive conditions, and to provide an empirically based understanding of the forces, flows and processes at work. This entails understanding processes of writing as an effect of complex relationships between the individual (the teacher and the student), the learning outcome, the affect, the talk, the motion, the body and the material. The results show how the writing project on some occasions come to a stop, sometimes take new directions or activate unforeseen affects and open for new becomings. The article also discusses how methods on the one hand has an explicit and formalized side, possible to articulate and predict. But on the other hand, is embedded in and driven by affects that changes both the method, the text production and the writing-learning subject. The article ends with a discussion of implications and possibilities understanding teaching methods of writing as dynamic processes that continually open for a variety of assemblages, flows and forces

Gynecomastia, a benign expansion of the glandular tissue in the male breast, is frequent in middle-aged and older males as well as in infancy and adolescence. Male obese patients frequently exhibit pseudogynecomastia, which is defined as fat-deposition without glandular proliferation. Its causes can be anything from uncommon neoplasms to harmless physiological processes. This systemic review aimed to examine surgical management strategies for gynecomastia. Data sources were PubMed/Medline and Embase. This review investigated English-language articles (from 2010 to 2023) according to the PRISMA guidelines. Surveys and analyses of national databases were the most widely used methods. The research identified 395 studies, out of which five were eligible for inclusion in the current analysis. Since estrogen and androgens are in balance in males, gynecomastia can be caused by any illness or medicine that raises or lowers the amount of circulating estrogen or androgen, respectively, resulting in an increase in the ratio of estrogen to androgen. Because there are so many potential causes, including neoplasms, a comprehensive history and physical examination are essential. Following the diagnosis of gynecomastia, treating the underlying cause is necessary. If underlying reason is not found then careful observation is necessary. Medical treatment might be an option if gynecomastia is severe and have started recently; if this proves unsuccessful, glandular tissue might be required to be removed surgically.

Amphibole peridotite and hornblendite of the Schrisheimite Hill intrusion of the Revdinskiy massif (Ural Platinum Belt)
Authors: Kozlov P. S. , Berzin S. V. , Ivanov K. S. , Yudin D. S.
Published: November 2023

Research subject. We studied the concentric-zonal massif (≈400 × 400 m) of amphibole-rich ultramafic rocks composed of amphibole peridotite (schriesheimite and amphibole wehrlite) with olivinite schlieren, pyroxenite and hornblendite located among gabbro at the Schrisheimite Hill in the Revdinskiy massif of the Ural Platinum Belt. The scope is characteristic of both of amphibole peridotites, which are extremely rare in the massifs of the Ural Platinum Belt, and the associated amphibole-rich ultramafic rocks. Aim. To expand the understanding of aqueous ultramafic magmatism in Ural Platinum Belt massifs. Materials and methods. To determine the age, we selected monofractions of high-alumina amphibole (pargasite-magnesiohastingsite) from two samples. Amphibole is not significantly altered by the regional metamorphism. 40Ar/39Ar dating was carried out according to the method described in (Travin et al., 2009; Yudin et al., 2021). The argon isotope composition was measured using a Micromass 5400 mass spectrometer (IGM SB RAS). Results. Amphibole peridotite has a hypidiomorphic (subhedral) or poikilitic texture. It is typical of igneous rocks, which indicates the crystallization of amphibole peridotite was by H2O-saturated magmas. Schlieren segregations of fine-grained schriesheimites and fine-grained olivinites are among coarse-grained schriesheimites. Amphibole peridotite, pyroxenite and hornblendite are deficient in high field strength elements (HFSE) and enriched in large ion lithophile elements (LILE) (with contrast concentration of Cs and Rb), which is typical of supra-subduction igneous formations. We obtained a 40Ar/39Ar age of 437.2 ± 6.7 Ma for an amphibole from hornblendite, which differs significantly from the ages of hornblendite determined earlier. Conclusions. Our new data indicate that hornblendite dikes in different UPB massifs formed over a fairly long time interval from the Early Silurian to the Early Devonian. These data expand modern ideas about the timing and nature of ultramafic water magmatism in the massifs of the Ural Platinum Belt.
Stylizing Asian
Authors: Wu Yifan
Published: November 2023

The paper examines the linguistic and cultural features Nigel Ng, a Malaysian comedian, utilized in his performance as Uncle Roger, a Cantonese English speaker, and the ensuing repercussions. The data analysis shows that a) Ng does not use all the features of Hongkong English, and his use of the features is inconsistent; b) Ng’s stylized English incorporates stereotypical linguistic features associated with several discrete ethnic varieties in the pan-Asian area; c) Ng's performance of Uncle Roger is a conscious media strategy to connect with a more diasporic audience. This paper therefore argues that Ng's performance is a racial stylization of pan-Asian. On the one hand, it challenges White hegemony by constructing a proud Asian identity and criticizing the misrepresentation of Asian cultures. On the other hand, it also reproduces stigmatized stereotypes by foregrounding out-group stereotypes of pan-Asians. The racial stylization discussed in this paper illustrates the double-edged nature of stylization.
“Equitable multilingualism” for equitable access to learning
Authors: Kim HaEun
Published: November 2023

Addressing the digital divide for refugee learners accessing higher education in displacement also involves addressing the linguistic divide, particularly as we live in a world of interlanguage inequality where academic digital resources and learning opportunities available largely require fluency in colonial languages like English, French, Spanish, etc. This paper focuses specifically on English as many connected tertiary programs available to refugees around the world are English-mediated. It is crucial that as connected higher education becomes a key strategy for access by the United Nations, INGOs, bilateral institutions, and private donors, universities involved in this work expand their use of technology to deliver programs to integrate technology-mediated language education for digital-skills, language awareness, and language development. This argument is based on an emancipatory approach that argues literacy (i.e., English literacy and digital literacy) only empowers people when it renders them active questioners of the social reality around them.
Unveiling the Veiled Narratives
Authors: Goodell Ugalde Elliot
Published: November 2023

Critical Indigenous scholars have extensively examined the issue of Missing and Murdered Indigenous Women/Girls (MMIWG) along the Highway of Tears (HoT) in British Columbia and have linked the phenomena to varying underlying colonial structures.[i] However, these analyses often overlook the central role of settler-colonialism in imposing patriarchal ontologies, which perpetuate ongoing Indigenous femicide. To address this theoretical oversight, this document adopts Linda Smith’s framework of ‘gendering’ as a means of decolonial praxis[ii] to incorporate feminist social reproduction theory into the discourse of Critical Indigenous scholars’ commentary on MMIWG. The aim is to shed light on how the problem of MMIWG is rooted in the imposition of colonial, patriarchal ontologies that disrupt matriarchal social reproduction along the HoT. Furthermore, this document argues that a critical examination of how settler-colonialism disrupts matrilineal social reproduction should occupy a more central position within postcolonial discourses focused on addressing MMIWG along the HoT as per considering the higher matrilineal governance of nations along the HoT.[iii] Ultimately, this document argues that a more comprehensive understanding of settler-colonialism’s impact on displacing Indigenous matrilineal social reproduction should be given greater emphasis when discussing the causal factors surrounding MMIWG along the HoT. By addressing the theoretical oversights and incorporating a gendered analysis within a decolonial framework, the paper aims to advocate for more effective approaches to address the issue.

On the Biopolitics of Suicide
Authors: Gan Zachary
Published: November 2023

This essay critically examines the biopoliticization of suicide, challenging its framing as a public health issue which obscures its cultural and philosophical significance. Drawing from Michel Foucault’s theories of biopower, this essay argues that suicide is externalized, massified, and medicalized under the discourse of public health, leading to its subjugation to biopower’s rhetoric. At the core of this narrative is a powerful presupposition that suicide is separable from the individual who commits the act. Drawing from Primo Levi’s The Drowned and the Saved and Judith Butler’s essay Violence, Politics, and Mourning, this essay conceives suicide as an intentional act of agency, occurring under particular conditions of emotional duress which are created by a historical relay of societal violence. This essay seeks to dismantle the prevailing narrative of suicide, free suicide from its biopolitical rhetoric, and argues that suicide ought to be understood as a radical act which bears witness against the violence of the biopolitical state.
Mediating Unresolved Conflict Through Dominant News Discourse
Authors: Cooling Christine Rose
Published: November 2023

Particularly in coverage of unresolved conflicts, mass media news of both the one-to-many broadcast era and the new networked era are not guaranteed to sufficiently provide the historical and analytical depth required for publics to understand these infinitely complex tensions in their respective cultural and temporal context. Mass media news coverage of the day, however, does perpetuate mediated images that seek to affect how publics contextualize and collectively remember simmering cultural conflicts into the future, afar and close to home. This article conducts a small-scale theoretical review of the theories of collective memory and agenda-setting, complemented by an analysis of mass media news coverage and literature on unresolved conflicts concerning the Front de libération du Québec (FLQ) and “The Troubles” in Northern Ireland. This interrogation, in light of theoretical conceptions of dominant news discourses, offers an explanation as to how publics may come to understand ongoing conflicts in the external world. In shaping understandings of unresolved conflicts by publics, mass media news can play a biased role in making certain political tensions affectively salient for the preservation of a nation’s collective past by attempting to influence how compassion is evoked from publics in the present and even into the future. While certainly historically and geopolitically situated, a commonality exists between the unresolved conflicts of the FLQ terrorist attacks in Québec, Canada and the Troubles in Northern Ireland: nationalist cultural tensions, ones that simmer cyclically until discontent erupts between players on opposing sides. Although apparent collectives can seek out countless contemporary alternative sources of information in the digital era of abundance, this paper argues that collective memory remains significant in the context of scrutinizing how mass media news problematically sets biased agendas, which then promotes quite different historical worldviews of deeply complex conflicts.
Confronting Propaganda
Authors: Faingersh Alisa
Published: November 2023

Education is facing a critical threat as those in positions of authority utilize propaganda to advance and promote an exclusionary worldview that serves their own interests. This essay focuses on one such misinformation campaign, which seeks to limit the rights of transgender individuals, including their very existence—a cause championed by right-wing politicians. The paper investigates how the American educational system fuels discrimination towards marginalized bodies, particularly transgender people, and suggests performative pedagogy as a strategy to counteract this oppression.

The essay begins by examining how the concept of performative pedagogy is used in contemporary drag shows and how deeply ingrained the idea of white supremacy is in transgender oppression. Through case studies, the paper shows how performative pedagogy serves as a powerful counter to the fundamental ideology of hatred. It explains how, through performative pedagogy, marginalized voices can be strengthened and serve as an effective communication tool for influencing society’s future by expressing what cannot be spoken through actions. This study argues that equipping today’s children with performative pedagogy enables them to withstand the challenges that they may face and helps them become more resilient in the face of difficulties. It draws attention to the fundamental responsibility of educators to teach for the benefit of society and to provide students with the skills necessary to face and overcome the challenges that will be used against them. Through the embracement of performative pedagogy, contemporary society can raise and foster a generation that actively opposes the oppressive forces that are reinforced and perpetuated by those in power.

Published: November 2023

The llama (Lama glama) and the alpaca (L. pacos) form the group known as domesticated camelids. They belong to the family Camelidae of the order Artiodactyla (ungulates). They are separated from other ruminants in the infraorder Tylopoda (footed) because they differ in gastric morphology (three compartments), with the absence of antlers or horns, and replacement of hooves with callous pads ending in claws (Novoa and Wheeler, 1984).
Camellias are tall, robust and the largest of the four camelid species. They are used to transport goods in Central and South America, where their meat is also used. The leather is used for shoes, sandals and bags. Their wool fiber is long and coarse, varying in color from white to black, and is used to make various clothing items. In our country, and in Europe in general, llamas and alpacas are used for leisure purposes and even as pets, in some cases their wool being used to create clothing products.
DESIGN AND REALIZATION OF DIRECTIONAL BIQUAD AND OMNIDIRECTIONAL BIQUAD ANTENNAS AS FIRST PERSON VIEW (FPV) RECEIVER ANTENNAS

Published: November 2023

UAV is an unmanned aerial vehicle controlled remotely by a pilot or automatically by pre-programmed instructions. UAVs are equipped with First Person View (FPV) technology, which facilitates user monitoring. FPV monitoring can be done using with goggles and a monitor screen. The monitor screens available in the market typically use dipole antennas as their default antennas. However, the drawback of the default monitor screen antenna is its limited range, typically only reaching up to 200-300 meters. This research focuses on the design and implementation of biquad antennas for FPV receivers in UAV systems operating at a frequency of 5.8 GHz. The aim is to create antennas with a larger reception range from the transmitter compared to the default FPV monitor screen antenna. Simulation results from CST Studio show that the directional biquad antenna has a VSWR value of 1.508, a return loss of -13.867 dB, and a gain of 3.416 dBi. On the other hand, the omnidirectional biquad antenna with 4 lobes has a VSWR value of 1.7065, a return loss of -11.666 dB, and a gain of 1.973 dBi. Meanwhile, the omnidirectional biquad antenna with 6 lobes has a VSWR value of 1.226, a return loss of -19.863 dB, and a gain of 1.865 dBi. In practical testing on the FPV monitor screen, all three types of antennas were successfully realized and able to capture real-time images from the UAV transmitter. The maximum distances achieved are 634 meters for the directional biquad antenna, 352 meters for the omnidirectional biquad 4 lobes antenna, and 545 meters for the omnidirectional biquad 6 lobes antenna.

Published: November 2023

Installation Wi-Fi is sometimes hindered by obstacles such as wood, concrete, and glass. The presence of these materials may affect the signal strength received by the user. Therefore, research was carried out by enclosing router using PVC, acrylic and glass materials with a thickness of 2mm, 3mm and 5mm and a distance of 2m, 4m, 6m, 8m, 10m, 12m, 10.2m and 11.4m for RSSI measurements and Quality of Service at a distance of 12m and 11.4m in the morning, afternoon and evening. The measurement results show a decrease in RSSI depending on the obstacle and distance. This is because the signal experiences diffraction and reflection which causes the signal strength to weaken and the farther the distance the weaker the signal. Measurements at the moment non-line of sight has quite poor results, especially when the glass barrier with a thickness of 5mm is at a distance of 11.4 with an average RSSI value of 74.6 dBm. QoS parameter results show Throughput When video streaming all have a bad category due to low number of packets. Parameter Packet Loss all of them are in a very good category, showing the least missing packets. Parameter Latency all of them have a very good category though Throughput low, influenced by the number of incoming packets. Parameter Jitter good with 2mm and 3mm barriers, while 5mm in the afternoon is moderate, influenced by Latency.

Ursolic acid (3-hydroxy-urs-12-ene-28-oic acid, UA) is one of the most notable pentacyclic triterpene which we have isolated from the biomass marc of the lavender plant Lavandula angustifolia. Then, UA was structurally modified by an introduction of indole ring at the C-3 position and amide group at the C-17 position with the aim to enhance its pharmacological potential. Firstly, we investigated the cytotoxic potential of all the synthesized derivatives in RAW 264.7 cells. The results of the study suggested that UA and its derivatives were non-cytotoxic to macrophages up to concentrations of 10.0 µM. In the present study we used Lipopolysaccharide (LPS), a potent activator of immune cells including macrophages consequently activating the inflammatory cascade. The nitric oxide (NO) inhibition was assessed for potential of these derivatives in LPS induced RAW 264.7 macrophages wherein the results demonstrated that among all, indole derivatives significantly reduced the levels of inorganic nitric oxide in cell culture supernatant in comparison to the parent molecule (UA) and as well as amide derivatives. Furthermore, compound 3 and 6 were evaluated for its cytokine inhibitory potential wherein, the results demonstrated that compound 3 and 6 significantly reduced the LPS-induced upregulation of pro-inflammatory cytokines (TNF-α, IL-6, IL-1β and PGE 2) and further upregulated the levels of anti-inflammatory cytokine (IL-10) in comparison to the UA in RAW 264.7 cells. The effect of these derivatives was also access on principal inflammatory mediators including iNOS, COX-2 and ROS. The results showed a reduction in the protein expression of iNOS and COX-2 indicating their potential role in dampening inflammation. Furthermore, ROS analysis demonstrated that both compound 3 and 6 significantly inhibited the LPS-induced reactive oxygen species. Additionally, molecular docking studies were performed to study the interaction of these hits with NF-κB protein. Since, it is a critical transcription factor that plays a central role in the regulation of the immune and inflammatory responses. The results of molecular docking demonstrated that these potent compounds might have worked through NF-κB signalling pathway, which might be the mechanism of action.

Long duration storage batteries such as Redox Flow Batteries (RFBs) are promising storage system to address the energy storage requirement that our society will require in the years to come. Recent effort has been focused on the development of metal free and high energy density system such as all-organic non-aqueous redox flow batteries (NAORFBs). However high-voltage NAORFBs currently use distinct anolytes and catholytes, which are separated by a membrane sensitive to osmotic pressure. This configuration results in permanent capacity and energy density fading rapidly with time. As an elegant solution, symmetric organic redox flow batteries (SORFB) have been proposed to address this issue. We recently reported the use of dimethoxyquinacridiniums (DMQA+) ions as efficient bipolar redox molecule (BRM) in static H-cell conditions. Herein, we are reporting the use of dimethoxyquinacridinium (DMQA+) ion, with a Egap of 2.1V and a theoretical energy density (Ed) to 14.9 Wh/L in CH3CN, as a bipolar redox molecule (BRM) in a full in flow RFB prototype and its ability to operate under polarity reversal. Essential kinetic properties of this molecule were assessed by cyclic voltammetry and correlated to DFT calculation. Its stability has been evaluated in static H-cell at two different concentration and then in full SORFB prototype. Although the coulombic and energy efficiency metrics were moderate, this pegylated DMQA+ exhibited a capacity retention of over 99.99%, and the property of operating under polarity inversion making it highly attractive for grid-scale long lifespan energy storage applications.
Understanding the initial events of the oxidative damage and protection mechanisms of the AA9 lytic polysaccharide monooxygenase family

Lytic polysaccharide monooxygenase (LPMO) is a new class of oxidoreductases that boosts polysaccharide degradation employing a copper active site. This boost may facilitate the cost-efficient production of biofuels and high-value chemicals from polysaccharides such as lignocellulose. Unfortunately, self-oxidation of the active site inactivates LPMOs. Other oxidoreductases employ hole-hopping mechanisms as pro- tection against oxidative damage, but little is generally known about the details of these mechanisms. Herein, we employ highly accurate theoretical models based on density functional theory (DFT) molecular mechanics (MM) hybrids to understand the initial steps in LPMOs’ protective measures against self-oxidation; we identify several intermediates recently proposed from experiment, and quantify which are important for protective hole-hopping pathways, and which lead to oxidative damage. Investigations on two different LPMOs show consistently that a tyrosine residue close to copper is crucial for protection: This explains recent experiments, showing that LPMOs without this tyrosine are more susceptible to self-oxidation.

The electrochemical reduction of oxidized nitrogen species enables a pathway for the carbon neutral synthesis of ammonia (NH3). The most oxidized form of nitrogen, nitrate (NO3-) can be reduced to NH3 via the nitrate reduction reaction (NO3RR), which has been demonstrated at high selectivity. However, to make NH3 synthesis cost-competitive with current technologies, high NH3 partial current densities (jNH3) must be achieved to reduce the levelized cost of NH3. Here, we leverage the high NO3RR activity of Fe-based materials to synthesize a novel active particle-active support system with Fe2O3 nanoparticles supported on atomically dispersed Fe-N-C. By synergizing the activity of both nanoparticles and single atom sites, the optimized 3xFe2O3/Fe-N-C catalyst demonstrates an ultrahigh NO3RR activity, reaching a maximum jNH3 of 1.95 A cm-2 at a Faradaic efficiency (FE) for NH3 of 100% and an NH3 yield rate over 9 mmol hr-1 cm-2. Operando XANES and post-mortem XPS reveal the importance of a pre-reduction activation step, reducing the surface Fe2O3 (Fe3+) to highly active Fe0 sites, which are maintained during electrolysis, to realize the ultrahigh NO3RR activity. Durability studies demonstrate the robustness of both the Fe2O3 particles and Fe-Nx sites at highly cathodic potentials, maintaining a current of -1.3 A cm-2 over 24 hours, a near unity FENH3. This work exhibits an effective and durable active particle-active support system enhancing the performance of the NO3RR, enabling industrially relevant current densities and near 100% selectivity.
De/colonising Theoretical Literatures and the Educational Qualifications to Unpack the Grotesque Skills Gap in South Africa

Published: November 2023

The research uses decolonial theory to delineate the conceptualisation of the academic qualifications provided by South African tertiary institutions and their relevance to closing the national skills gap. Decolonising the South African educational system represents a progressive approach that is new to both students and educators. Both government and employers acknowledge a skills shortage in South Africa. However, the question of where the skills should be provided is unanswered. Graduates are expected to have specific skills before entering the labour market. The study uses desktop research that focuses on secondary data to explore the phenomenon. The research has two objectives: to present a decolonial explanation of the relationship between academic qualifications and national skills needs and to explore ways of integrating current academic qualifications offered by educational institutions in South Africa to address the national skills gap. The study explores how the content of the National Qualification Framework and its relevance in skills development can be decolonised. The study found that the existing educational qualification programmes in South African tertiary institutions are unable to address the skills gap effectively due to emerging needs highlighted in recent literature. To address this issue, there is a need to restructure academic qualifications to better align them with the country's skill shortages or explore alternative approaches to aligning knowledge and skills. The study recommends examining the national skills shortage beyond the higher education institutions’ academic structure and looking at other factors, such as workplace discrimination in training and development. Collaboration between stakeholders, employers and tertiary education institutions should be encouraged for curriculum development and alternative means of skills acquisition.
