Combustion Assisted Synthesis of CuO Nanoparticles and Structure-Property Evaluation in nano-CuO Polymer Composites
Authors: Prasanth Gopinath , Madhu Gattumane Motappa , Kottam Nagaraju
Published: November 2023

Metal oxide-based nanoparticle as a filler in epoxy polymer composites has diverse applications in various industries, including adhesives, automobiles, aerospace, wind energy, and civil engineering. However, these composites must fulfill essential properties encompassing chemical, curing, optical, and thermal attributes. This study focuses on enhancing epoxy polymer by integrating copper oxide (CuO) nanoparticles synthesized through solution combustion. Varied CuO loadings (0.5–2.5 wt.%) were impregnated into the epoxy, critically impacting the structural attributes of the resulting nano-CuO polymer composites. Various material characterization techniques were employed to study the synthesized materials' morphology, elemental composition, phase formation, identification of the presence of functional groups, thermal stability, and optical properties. SEM images show the presence of spherical particles with porous structures. EDX confirmed the presence of Cu and O elements, while the XRD pattern showed the formation of CuO with an average crystallite size of 46 nm. FTIR confirms the presence of O-H, C-H, and C=C functional groups. TGA showed thermal stability and revealed minimal mass loss below 250 °C for nano-CuO polymer composites and minimal mass loss occurred for CuO nanoparticles at 900 °C. Photoluminescence exhibited redshifted luminescence spectra. The study suggests improved qualities due to CuO nanoparticle integration into epoxy. CuO loading crucially influences nano-CuO polymer composite properties, rendering them ideal for high-temperature applications, supported by remarkable thermal stability evidenced by substantial residual mass in TGA.

Interior mobil yang pada umumnya terbuat dari bahan-bahan sintetis yang dapat mengemisikan Volatile Organic Compound (VOC) apabila berada pada suhu yang tinggi, salah satunya adalah senyawa benzene. Selain berasal dari emisi bahan-bahan yang digunakan pada interior mobil, konsentrasi senyawa benzena dapat pula dipengaruhi oleh hal lain, diantaranya: kondisi udara ambien, kebocoran gas dari tangki bahan bakar dan tabung penghantar bahan bakar, infiltrasi emisi kendaraan lain di tempat parkir, dan lain sebagainya. Pada penelitian ini akan dibandingkan konsentrasi benzene di dalam kabin mobil pada 3 kondisi berbeda, yaitu berdasarkan durasi penjemuran mobil 2 jam, 4 jam, dan 6 jam secara active sampling dan dianalisis menggunakan gas kromatografi-spektrometer massa (GC-MS). Sebagai pembanding, akan diukur pula konsentrasi benzena pada mobil yang ditempatkan di dalam garasi tanpa terpapar sinar matahari secara langsung. Hasil penelitian terukur keberadaan benzena di dalam kabin mobil pada kondisi tanpa ventilasi dan pendingin dengan konsentrasi antara 0.77 – 1.36 mg/m³. Konsentrasi tersebut berkorelasi signifikan secara statistik dengan temperatur dalam kabin sehingga semakin tinggi temperatur akan semakin tinggi pula konsentrasi benzena di dalam kabin mobil. Terdapat pula kemungkinan infiltrasi benzena dari lingkungan luar mobil. Hasil penelitian ini meningkatkan kesadaran pengguna mobil mengenai adanya pencemar udara berbahaya pada kabin mobil saat sedang tidak dipergunakan terutama apabila berada pada tempat dengan temperatur tinggi dan terdapat sumber pencemar benzenekabin mobil, benzena, GC-MS , VOC
Interaction of Organisms in Abandoned Tin Mining Pits: Perspective of Life in Acid Mine Drainage Environment
Authors: Kurniawan Andri , Kurniawan Ardiansyah , Robin Robin
Published: November 2023

Acid Mine Drainage (AMD) occured after mining activity exposes metal sulphides to oxidizing conditions that impact acidic condition with low pH value in the waters and heavy metals contamination. These conditions are also occurred in abandoned tin mining pits, one of placed in Bangka Belitung Archipelago Province. This mini review aimed to elaborate information of micro- and macro-organism’ life in acid mine drainage to be associated with the possibility of life in abandoned tin mining pits. Acidophilic and acidotolerant organisms such as bacterial, phyto- and zooplankton, and some macroorganism included invertebrate or vertebrate like fishes and also water plants were found in these waters. Their presence developed a symbiosis interaction in aquatic environment. Phytoplankton is an autotroph organism, despite being considered autotroph organism, many phytoplankton require exogenous organic cofactors and nutrients for their life. These cofactors were often served by heterotroph bacterial to sustain the growth of phytoplankton. Instead, bacterial obtained dissolved organic matter derived from phytoplankton to survive in the aquatic environment. Furthermore, phytoplankton was consumed by zooplankton; zooplankton was consumed by small fish to big fish in the waters. In addition, water plants also support the interaction of organisms in the water by supplying dissolved oxygen, also anorganic and organic material for their life. The symbiosis and quorum sensing plays an important role in structuring the aquatic food web and creating a life in the acidic water-polluted heavy metal.

Authors: Ayub Ayub , Noorachmat Bambang Pramudya , Purwanto Muhammad Yanuar Jarwadi
Published: November 2023

The increased populism should be offset by increased food production; thus, the region's food security can be maintained. Food security will not be resolved if it does not solve the root of the problem, namely the farmers' deterioration and the agricultural land conversion. The primary purpose of this study is to design a dynamic model of sustainable food farming—the methods used in achieving an approach with a dynamic system. Needs analysis, problem formulation, system identification, system modeling, model validation, and implementation are the stages in problem-solving with the systems approach method. The Powersim Studio software analyzes the system and views model behavior. Based on the predicted results, in 2021, Bantul Regency experienced a deficit rice of 1,925 tons without control efforts. A pessimistic scenario with a control policy of 50% of the rice field function transfer rate caused the rice balance sheet to be a deficit of 1,001 tons. Optimistic scenario, control of paddy field conversion 50% of the transfer rate and food diversification obtained rice balance with a surplus of 5,460.24 tons by 2030.

Reframing self-talk in endurance sports using grammatical taxonomy
Authors: Wallentin Mikkel , Nedergaard Johanne S. K.
Published: November 2023

In this theoretical paper, we use a linguistic vocabulary to reframe self-talk in endurance sport through a focus on grammatical function. Self-talk often works as speech acts, a kind of communicative action, e.g. where a self-talker is using the imperative mood to accomplish some goal with respect to herself (Come on!). Auxiliary modal verbs work across three main types of utterances: Deontic modality involving permission and obligation; dynamic modality involving ability and willingness; epistemic modality involving probabilistic judgements. In self-talk, these all function to establish a hypothetical domain for further reflection. Self-distance can be negotiated using 1st and 2nd person pronouns (I/you) and spatial demonstratives (this/that). Sentiment is communicated using adjectives, while negation may yield a means for impulse control. We can question our own utterances and use interjections to communicate surprise. These are all vital mental tools in endurance sports and an increased awareness of their functions in self-talk research will likely yield better self-talk interventions and lead to better performance for athletes.
Bioprospecting for improved floral fragrance in wild sunflowers
Authors: Anandappa Jason A. , Stanford Hannah E. , Marek Laura F. , Goolsby Eric W. , Mason Chase M.
Published: November 2023

Cultivated sunflower (Helianthus annuus) is not typically considered to have a pleasant floral fragrance. In field production, seed yield is often limited by pollination services, particularly in the production of hybrid seed. Improved floral fragrance, as determined by volatile organic compounds, may be a route to improving pollinator attraction for oilseed and confectionary production and could also add value to ornamental sunflowers. Wild relatives of H. annuus have a long history of being used to breed improved traits into cultivated varieties, yet it is unknown whether favorable scents are present in wild Helianthus species and thus an available resource for fragrance breeding. In order to assess the diversity of floral fragrance available in crop wild relatives, 30 diverse accessions of wild Helianthus as well as seven varieties of H. annuus spanning a domestication gradient were grown in greenhouse experiments and variation in floral volatiles was analyzed by solid phase microextraction-gas chromatography-mass spectrometry. While alpha-pinene made up a significant portion of the volatiles emitted for most taxa, there was substantial diversity present across the genus as well as within H. annuus. Most volatiles emitted were monoterpenoids with a significant share of sesquiterpenoids. The diversity identified here will inform further targeted study of which compounds affect pollinator attraction and health. Several wild accessions such as Helianthus debilis subsp. tardiflorus and Helianthus praecox subsp. praecox as well as open-pollinated domesticated accessions of H. annuus show promise for breeding for improved floral fragrance due to high volatile abundance and likely favorable compound compositions.
Durchkreuzte Länder, verschobenes Begehren
Authors: Kraß Andreas
Published: November 2023

This article is intended to illustrate how helpful it is to incorporate the theoretical and methodological approaches of Queer Studies and Intersectionality Studies into (medievalist) literary studies. As the analysis of the medieval narrative Herzog Ernst will show, gender relations become visible in this way that tend to remain hidden to a heteronormative perspective. It has for a long time been controversial whether Herzog Ernst can be interpreted as a bridal-quest epic. This article argues that this is not only possible, but even essential – albeit in unforeseen ways.
Stimme, Name, Geschlecht.
Authors: Blödorn Andreas
Published: November 2023

This article aims to further discussions about a queer reading. An exemplary reading of Christoph Martin Wieland’s Novella without a Title (1803/1805) is particularly interested in the inconsistencies within in this text’s exploration of the multidimensional concept of “Geschlecht” (sex/gender, kinship, and the human species). A narratological queer reading in this sense lays thus open the openings and closures of the text.
Literarisches Schreiben post Hanau
Authors: El Hissy Maha
Published: November 2023

The following contribution begins with an overview of a history and critique of the contemporary usage of the term postmigrant art and literature. I then examine the writing by authors of colour in Germany after the racist killings in the city of Hanau in 2020. Taking Shida Bazyar’s novel Sisters in Arms (Drei Kameradinnen) as a point of departure, I investigate what I refer to as the art and politics of confusion and ambivalence. As I discuss within the context of the novel, the narrative strategies and aesthetics reflect racist practices of victim blaming, evidence tampering and the scandalous failure of state institutions to restore justice or fight the rising threat from the far-right.
Nach der Coolness
Authors: Brinkmann Lena Marie
Published: November 2023

From the protective strategy of a minority to a popular consumer argument, coolness has come a long way. Once celebrated as a mark of distinction in pop literature, the question today is whether coolness is not long outdated when it comes to writing about issues and views of postmigrant realities that keep the political public in suspense. This article explores aspects and varieties of coolness in Deutschboden (2010) and Nochmal Deutschboden (2020) by Moritz von Uslar and addresses the question of whether the cool attitude can still serve as a cultural practice and aesthetics of self-assertion.
Ewig Peripherie?
Authors: Böttcher Philipp
Published: November 2023

Based on sociological approaches to the relationship between inequality and space, the article analyses the connections between spatial, class and post-migration perspectives in Deniz Ohdeʼs Streulicht. In particular, the urban periphery that features as the location of the novel is both a literary and socially representative space. In the text social and individual-mental aspects are negotiated through the representation of space. This also includes the xenophobic attributions that the narrator experiences from her environment.
Identität und Perspektive

Current discourses of postmigrant societies heavily draw on the notion of perspective, a leading metaphor of modern pluralist thought that is prominent in narratological discourse as well. Taking up Hans Blumenberg’s question of the possibility of the novel, the following contribution asks if and how the narrative art of perspectivism might be able to meet the challenge posed by recent changes in society.
La vicenda de Dante en la Península Ibérica: primeros hitos poéticos y traducciones
Authors: Hamlin Cinthia María
Published: November 2023

Como ha destacado Valero Moreno (2021), el arribo de la Commedia a territorio ibérico solo puede entenderse en la interacción de tres vías: la circulación manuscrita, la creación poética y la de sus traducciones. En este artículo me dedicaré a dar cuenta del primer indicio atestiguable de su llegada y circulación, esto es, el de la creación poética, así como a su posterior proyección e influencia en la poesía de los siglos XIV, XV y XVI. La parte central del artículo, sin embargo, estará dedicada a la “última” de las tres vías de ingreso y circulación de Dante en la Península: sus traducciones. Ríos de tinta han corrido sobre el tema, por lo cual intentaré ofrecer un panorama renovado en el que, además de reunir los avances de las últimas investigaciones en torno a las características y problemas textuales de cada una, delinearé algunos de los problemas o aspectos no abordados, posibles modos de continuar su estudio, así como nuevos datos que se desprenden de mis propias investigaciones.

The Nexus of COVID-19 and Climate Change: A Systematic Literature Review
Authors: Mestre Garcia Carolina , Savin Ivan , van den Bergh Jeroen
Published: November 2023

Since the onset of the COVID-19 pandemic, many studies have appeared on how it will affect climate change and policy, and vice versa. In this study, we systematically review the literature about this relationship. We obtained a sample of 204 articles published in the period from February 2020 to March 2022. Using topic modelling and qualitative analysis, we identify seven main topics on the nexus of COVID-19 and climate change: (1) impacts of COVID-19 on climate change and policy; (2) sustainable recovery after COVID-19; (3) public concern about climate change and COVID-19; (4) lessons from COVID-19 for climate change action; (5) effects of COVID-19 and climate change on the economy, food security and poverty; (6) collective responses to crises and (7) similarities and differences between COVID-19 and climate change. We discuss lessons derived from each of these topics and identify key policies and strategies for a sustainable recovery from COVID-19. Investments in low-carbon technologies and carbon taxation are the most commonly suggested policy solutions. If climate targets are to be met, climate action needs to be the focus of COVID-19 recovery.
Creative Appropriations:Everymanon the Contemporary Stage
Authors: Rössler Julia
Published: November 2023

The morality taleEverymanhas in recent years seen a notable renaissance in contemporary theater:Everybody(2017) by US American playwright Branden Jacobs-Jenkins, Carol Ann Duffy’s adaptation ofEveryman(2015) at the National Theatre in London, and director/playwright Milo Rau’s workEverywoman(2020) have turned to it. In this article, I conceptualize these theatrical works as creative appropriations which stage the vexing relation between canonical text and contemporary theater practice. They are marked by an ambivalent dynamic in that they are far less conclusive about their own return to and reworking of the literary source. Their mode of representation oscillates between adaptation, appropriation, and playful de- and reconstruction. Despite evident contrasts in theme and form, these works openly reference their literary source and draw destabilizing effects from their montage of different modes of language and writing (citational speech, self-narration, confession) and performative elements. As I argue, however, these productions cannot be easily aligned with postdramatic theory’s advocation of a deconstructivist approach towards the dramatic text. The text, rather, is treated as an archive of poetic figures, narrative ideas, and moral concerns. In these productions, the textual material is not deconstructed but rather blended, momentarily decentered, and interwoven with vital performative elements (media, dance, collective speaking) which allows each creative appropriation to explore how canonical literary sources may speak to our contemporary culture and society.
Relations with/to the Text: Four Plays on the Move
Authors: Schmidt Kerstin
Published: November 2023

The Caribbean philosopher and poet Édouard Glissant is not known for his work on theater; rather, he has been influential for a postcolonial reconceptualization of Caribbean spaces and the ways in which they are intertwined with a history of colonization. His theory of relation has been paramount for a rethinking of a concept of connection, theorizing the layered, complex, and often surprising relations between peoples and cultures that have shaped, questioned, imagined, and often also jumbled up the Caribbean as a world in transformation. Glissant views relation as a skein of networks and not as essentialist recovery of an authentic and true point of origin. This article addresses the theoretical transformative possibilities that this approach helps elucidate. I will mainly focus on the production of Simon Stephens’s 2012 The Curious Incident of the Dog in the Night-Time, an inventive adaptation of Mark Haddon’s 2003 novel that was staged in New York City between 2014 and 2016 to much critical acclaim. Finally, in a comparative approach, I would like to read this production with an eye towards Susanne Kennedy’s 2018 adaptation of Jeffrey Eugenides’s novel The Virgin Suicides (1993) for the Munich Kammerspiele and acclaimed Australian theater director Simon Stone’s 2016 rewrite of Anton Chekhov’s Three Sisters (1901) for the theater in Basel as well as Ulrich Rasche’s inventive 2017 production of Georg Büchner’s Woyzeck.

Over the past two decades, the industrialization of film and its discursive space have presented an open trend. Chinese film industry studies encompass multidimensional connotations involving economics, culture, and ideology. National will and policy-driven initiatives form the underlying logic of “industry studies,” while market-oriented approaches connect attention with the commodification of films, becoming the domain for the industry’s transformation. In the past twenty years, the industrial reform process of the Chinese film industry, along with innovations in film policies and institutions and their implementation, has reflected and outlined this multifaceted context. The film industry possesses the attributes of economy, culture, and ideology and, as a public good, includes issues related to attention orientation and correction. The construction of Chinese film industry studies, and the in-depth examination of the results and issues related to market discourse, is significant for further promoting the sustainable development of the film industry and fostering the prosperity of Chinese cinema.
The Thule Migration: A Culture in a Hurry?
Authors: Park Robert W.
Published: November 2023

The process by which the Thule Inuit migrated from the region around Bering Strait into Arctic Canada and Greenland, which is notable for its logistical complexities, the varied and difficult regions traversed and then populated, and for the enormous distance covered, is almost invariably described in terms emphasizing the pace at which it took place. The most common description is “rapid,” and some descriptions conclude it may have been accomplished within just a few decades, despite researchers not having explored the logistical and demographic implications of that inference. This article explores several possible meanings of “rapid” in the context of the Thule migration and reviews the evidence that is informative concerning its pace, including radiocarbon dates, historical encounters, logistics, and demography. It concludes that the Thule Inuit may indeed have felt a sense of urgency to expand into new regions, but they did this at a far slower pace than most researchers have concluded, over centuries rather than decades.

Published: November 2023

Photocatalysis is an effective way to alleviate the energy crisis and environmental pollution. Bismuth Chloride Oxide (BiOCl) is one of the most widely studied metal oxides due to its unique surface and electronic structure. However, the wide band gap of BiOCl and the high complexation rate of photogenerated electron–hole pairs limit its photocatalytic efficiency. Increasingly, efforts are being made to improve the performance of this range of photocatalysts. The article reviews the progress of research to enhance the photocatalytic activity of BiOCl nanomaterials. Strategies to improve the photocatalytic performance of single-phase BiOCl include morphological control, component adjustment, crystal facet control, and defects construction. Strategies to improve the photocatalytic activity of BiOCl-based composites include surface modification, immobilization of photocatalysts, impurity doping, and the construction of heterojunctions. In addition, the challenges and trends of BiOCl photocatalysts are discussed and summarized. Hopefully, this review will be helpful for the research and application of BiOCl photocatalysts.

Motile cells encounter microenvironments with locally heterogeneous mechanochemical composition. Individual compositional parameters, such as chemokines and extracellular matrix pore sizes, are well known to provide guidance cues for pathfinding. However, motile cells face diverse cues at the same time, raising the question of how they respond to multiple and potentially competing signals on their paths. Here, we reveal that amoeboid cells require nuclear repositioning, termed nucleokinesis, for adaptive pathfinding in heterogeneous mechanochemical micro‐environments. Using mammalian immune cells and the amoeba Dictyostelium discoideum, we discover that frequent, rapid and long‐distance nucleokinesis is a basic component of amoeboid pathfinding, enabling cells to reorientate quickly between locally competing cues. Amoeboid nucleokinesis comprises a two‐step polarity switch and is driven by myosin‐II forces that readjust the nuclear to the cellular path. Impaired nucleokinesis distorts path adaptions and causes cellular arrest in the microenvironment. Our findings establish that nucleokinesis is required for amoeboid cell navigation. Given that many immune cells, amoebae, and some cancer cells utilize an amoeboid migration strategy, these results suggest that nucleokinesis underlies cellular navigation during unicellular biology, immunity, and disease.

Objectives

The aim was to evaluate the clinical, ultrasound (US) and, when indicated, the cytological and histological characteristics of autonomously functioning thyroid nodules (AFTN) in consecutive patients.

Methods

A prospective, single-centre study was conducted between March 2018 and September 2021. In total, 901 consecutive patients were referred for thyroid workup and of 67 AFTN were evaluated. All enrolled patients underwent 99mTcO4
− scintigraphy, additional 123I scintigraphy only in case of normal serum TSH, evaluation of thyroid function, US examination using European Thyroid Imaging and Reporting Data System (EU-TIRADS), and US-guided fine needle aspiration (FNA) cytology when indicated. All indeterminate FNA samples were subjected to DNA sequencing analysis.

Results

More than half of the evaluated patients with AFTN were euthyroid; median serum TSH was 0.41 (IQR: 0.03–0.97) mU/L. The median AFTN size measured by US was 27.0 (IQR: 21.1–35.0) mm. 28.4% of AFTN were classified as EU-TIRADS score 3 and 71.6% as EU-TIRADS score 4, indicating that the majority of AFTN had intermediate risk for malignancy according to US. Out of the 47 AFTN subjected to cytological evaluation, 24 (51%) yielded indeterminate FNA results. DNA sequencing revealed pathogenic TSHR and GNAS mutations in 60% of cases. No malignancy was detected at final histology in surgically excised AFTN (n = 12).

Conclusions

Of the 67 AFTN evaluated in this study, 50% presented with normal serum TSH, 70% displayed ultrasound features suggesting an intermediate malignancy risk and 50% of the AFTN submitted to cytology yielded indeterminate results. No malignant AFTN was detected.
Challenges and prospects for activating a circular economy in the context of sustainable waste management in Algeria
Authors: Hassaine Mahfoudh , Abrika Belaid
Published: November 2023

The article deals with the problem of waste management in Algeria. It aims to analyze the various policies undertaken by the government in order to be able to respond to the principles of sustainable development and the circular economy from the perspective of sustainable and integrated waste management. The analyses carried out show that the first waste management strategies in Algeria are more reactive and constitute a response to the crisis of the proliferation of waste. It is only from the year 2016 that the national integrated waste management strategy constitutes a perspective of registration of this sector in a circular approach of profitability and sustainability.
