Authors: Liu Zeqiu , Yang Sikang , Han Yu , Hao Tengfei , Zhang Minming , Li Ming , Zhu Ninghua
Published: January 2023

Effective manipulation of resonant mode, output power and modulation bandwidth of lasers are all of vital importance for practical application scenarios such as communication systems. We show that by breaking the parity-time (PT) symmetry, single mode operation lasing can be realized in an intrinsic multiple mode Fabry-Perot (FP) resonator. Two identical FP resonators are employed to establish a symmetric system and high output power can be achieved with lower fabrication difficulty and intracavity losses compared with ring resonators. The small-signal response and direct modulation of the PT-symmetric FP laser have also been demonstrated with electrical pumping. Our work opens new avenues for mode selection of high-performance FP lasers and provides a cost-effective candidate for practical applications such as communication systems.
Resonance coupling between chiral quasi-BICs and achiral molecular excitons in dielectric metasurface J-aggregate heterostructures

Published: January 2023

The realization of flexible tuning and enhanced chiral responses is vital for many applications in nanophotonics. This study proposes to manipulate the collective optical responses with heterostructures consisting of chiral dielectric metasurfaces and achiral J-aggregates. Owing to the resonance coupling between the chiral quasi-bound states in the continuum (QBICs) and the achiral exciton mode, large mode splitting and anticrossing are observed in both the transmission and circular dichroism (CD) spectra, which indicates the formation of hybrid chiral eigenmodes and the realization of the strong coupling regime. Considering that the radiative and dissipative damping of the hybrid eigenmodes depends on the coherent energy exchange, the chiral resonances can be flexibly tuned by adjusting the geometry and optical constants for the heterostructure, and the CD of the three hybrid eigenmodes approach the maximum (∼1) simultaneously when the critical coupling conditions are satisfied, which can be promising for enhanced chiral light–matter interactions.
Compensation of scale factor nonlinear error introduced by harmonic distortion for open-loop fiber optic gyroscopes
Authors: Zhu Lanxin , Cao Yuwen , Huang Huimin , Chen Yanjun , Wang Wenbo , Ma Xiangdong , Li Zhengbin
Published: January 2023

The scale factor (SF) of a gyroscope is the ratio of the detection output rotational rate and the input, and is expected to be a constant. However, for open-loop interferometric fiber optic gyroscopes (IFOGs) with sinusoidal modulation, harmonic amplitudes are inevitably affected by detection defects, such as nonuniform frequency response of the photodetector or unequal gain of amplification circuits. As a result, harmonic distortion leads to SF nonlinearity, which seriously hinders the accuracy of high-precision gyroscopes. In this Letter, the theoretical form of the SF error introduced by harmonic distortion of open-loop gyroscopes is analyzed, and an effective and simple compensation method is proposed. Instead of traversing the whole dynamic range, the proposed method simplifies the calibration pretest, where only a section of the dynamic range needs to be tested. Experimental results on an open-loop IFOG prototype show that, with our proposed method, the SF nonlinear error is suppressed to 2.5 ppm within the range −300 to +300∘/s, which is 33 times less than that before compensation.

Published: January 2023

Trapping and manipulating mesoscopic biological cells with high precision and flexibility are very important for numerous biomedical applications. In particular, a photonic nanojet based on a non-resonance focusing phenomenon can serve as a powerful tool for manipulating red blood cells and tumor cells in blood. In this study, we demonstrate an approach to trap and drive cells using a high-quality photonic nanojet which is produced by a specific microcone-shaped optical-fiber tip. The dynamic chemical etching method is used to fabricate optical-fiber probes with a microcone-shaped tip. Optical forces and potentials exerted on a red blood cell by a microcone-shaped fiber tips are analyzed based on finite-difference time-domain calculations. Optical trapping and driving experiments are done using breast cancer cells and red blood cells. Furthermore, a cell chain is formed by adjusting the magnitude of the optical force. The real-time backscattering intensities of multiple cells are detected, and highly sensitive trapping is achieved. This microcone-shaped optical fiber probe is potentially a powerful device for dynamic cell assembly, optical sorting, and the precise diagnosis of vascular diseases.
Community composition exceeds area as a predictor of long-term conservation value
Authors: O’Sullivan Jacob D. , Terry J. Christopher D. , Wilson Ramesh , Rossberg Axel G.
Published: January 2023

Conserving biodiversity often requires deciding which sites to prioritise for protection. Predicting the impact of habitat loss is a major challenge, however, since impacts can be distant from the perturbation in both space and time. Here we study the long-term impacts of habitat loss in a mechanistic metacommunity model. We find that site area is a poor predictor of long-term, regional-scale extinctions following localised perturbation. Knowledge of the compositional distinctness (average between-site Bray-Curtis dissimilarity) of the removed community can markedly improve the prediction of impacts on regional assemblages, even when biotic responses play out at substantial spatial or temporal distance from the initial perturbation. Fitting the model to two empirical datasets, we show that this conclusions holds in the empirically relevant parameter range. Our results robustly demonstrate that site area alone is not sufficient to gauge conservation priorities; analysis of compositional distinctness permits improved prioritisation at low cost.
Value addition and farmers: Evidence from coffee in Ethiopia
Authors: Tamru Seneshaw , Minten Bart
Published: January 2023

Local value-addition in developing countries is often aimed at for upgrading of agricultural value chains, since it is assumed that doing so will make farmers better off. However, transmission of the added value through the value chain and constraints to adoption of value-adding activities by farmers are not well understood. We look at this issue in the case of coffee in Ethiopia–the country’s most important export product–and value-addition in the coffee value-chain through ‘washing’ coffee, which is done in wet mills. Washed coffee is sold internationally with a significant premium compared to ‘natural’ coffee but the share of washed coffee in Ethiopia’s coffee exports has stagnated. Relying on a unique primary large-scale dataset and a combination of qualitative and quantitative methods, we examine the reasons for this puzzle. The reasons seemingly are twofold. First, labor productivity in producing red cherries, which wet mills require, is lower than for natural coffee, reducing incentives for adoption, especially for those farmers with higher opportunity costs of labor. Second, only impatient, often smaller, farmers sell red cherries, as more patient farmers use the storable dried coffee cherries as a rewarding savings instrument, given the negative real deposit rates in formal savings institutions.
Time-optimal trajectory planning based on event-trigger and conditional proportional control
Authors: Chen Guangrong , Wei Ningze , Yan Lei , Lu HuaFeng , Li Jin
Published: January 2023

Trajectory planning is an important issue for manipulators and robots. To get a optimal trajectory, many constraints including actuators specifications, motion range of joints, workspace limitations, etc, and many objectives including the shortest time, the shortest distance, the lowest energy consumption, the minimum oscillations, obstacles-avoiding, etc, should be considered both. In this paper, firstly, the forward kinematics and inverse kinematics of a five axis manipulator are deduced. And, a simple method to choose one appropriate solution from multi solutions of inverse kinematics is proposed. Secondly, an easy-implemented optimization method of trajectory planning is proposed based on seventh order polynomial interpolation, event-trigger mechanism and conditional proportional control (P control). The proposed optimization method can capture the time optimal trajectory, and the actuators specifications including velocity, acceleration of motor can be guaranteed as well. Thirdly, comparative simulations and experiments validate the effectiveness and efficiency of proposed optimization method. The research provides an insight for the application of trajectory optimization on the micro controller with low computing capability and high real-time performance requirement.

Fifteen quinazoline derivatives were designed and synthesized as DNA intercalators. The cytotoxicity of the designed members was assessed against HCT-116 and HepG2 cancer cell lines. In addition, the topoisomerase II (Topo II) inhibitory effect was assessed. Compound 16 was the most cytotoxic and Topo II inhibitor with low cytotoxicity against Vero cells. Compounds 16, 17, and 18 showed significant DNA binding affinities. Compound 16 showed Topo II catalytic inhibitory effect at a concentration of 10 μM. Further mechanistic investigations revealed the capability of compound 16 to induce apoptosis in HCT-116 cells and arrest the growth at the S and G2/M phases. Also, compound 16 showed a significant increase in the level of BAX (2.18-fold) and a marked decrease in the level of Bcl-2 (1.9-fold) compared to the control cells. In silico studies revealed the ability of the synthesized members to bind to the DNA-Topo II complex.

Published: January 2023

This study aimed to examine sarcopenia prevalence using the Asian Working Group for Sarcopenia 2019 (AWGS) and the Foundation for the National Institutes of Health (FNIH) definitions, and their associations with important health conditions affecting midlife Singaporean women. Muscle mass and function were objectively assessed in 1201 healthy community-dwelling subjects aged 45–69 years under the Integrated Women’s Health Program (IWHP). Dual-energy X-ray absorptiometry (DXA), handgrip strength and the Short Physical Performance Battery (SPPB) were measured, and the relationship between sarcopenia with hypertension, type 2 diabetes (T2DM), osteoporosis, depression/anxiety, and urinary incontinence were examined using binary logistic regression models. Sarcopenia prevalence was 18.0% and 7.7% by the AWGS and FNIH criteria respectively. Osteoporosis (aOR: 1.74, 95% CI: 1.02, 2.94) and T2DM (aOR: 1.98, 95% CI: 1.14, 3.42) was positively associated with AWGS- and FNIH-defined sarcopenia respectively, while hypertension was not, after adjustment for age, ethnicity, education levels and menopausal status. A negative percent agreement of 95.6% suggests good agreement between the criteria in the absence of sarcopenia. Even though they represent a single concept, sarcopenia by either criterion differed in their relationships with diabetes and osteoporosis, suggesting the need for further rationalization of diagnostic criteria.
Migration information campaign through music: The effect of Kofi Kinaata’s highlife song on young people in Ghana
Authors: Eshun Samuel Nuamah , Agyekum Boadi
Published: January 2023

Since 2014 over 2 million people have arrived at the shores of Europe through irregular crossing. This has created huge socio-economic consequences for the European people. In a bid to solve this unprecedented migrant crisis, the European Union and its member states have implemented migration information campaign (MIC) as part of a remote border control strategy to curb irregular migration. In Ghana, Kofi Kinaata was selected as a goodwill ambassador and his song, entitled ‘No Place Like Home’ is part of a broader advocacy programme that was implemented in West Africa to reduce irregular migration. This study seeks to investigate the effects of Kofi Kinaata’s song on the migration intention of young people in Ghana. The study is a qualitative descriptive study involving sixteen participants in the Cape Coast Metropolis in Ghana. The study revealed that young people with the ambition of migrating irregularly are already aware of the fear messages used by sponsors of MICs, though they still want to travel through the irregular way. It is therefore recommended that investment in remote border control by European countries should focus more on reducing poverty and creating jobs in migrant source countries since these are the key factors driving irregular migration. Immigration policies by EU countries and other migrant receiving countries should also be relaxed making room for alternative affordable and safe pathways to migration. This article has also called on governments in migrant source countries to strengthen their institutions to deal with poverty and regulate migration. This will go a long way to curb the menace of irregular migrants in Europe and elsewhere.
Vietnamese refugee journeys and the fallacy of certainty
Authors: Graham Janet
Published: January 2023

Vietnamese diasporic refugee narratives critically engage images of helicopter rescues and crowded boats that saturate American-mediated memories of war’s aftermath. From a critical refugee studies perspective, Yến Lê Espiritu links war to displacement through these images to define the United States as a ‘militarized refuge’. For Mimi Nguyen, arrival initiates a ‘gift of freedom’ that names the indebtedness of the refugee to the state. In their critical engagements, arrival initiates debt for militarized refugees. To further their work, I problematize the celebration of arrival with what I call the fallacy of certainty. To dismantle the certainty of arrival, I examine expressions of what Vinh Nguyen calls ‘refugeetude’ in depictions of refugee journeys by Ocean Vuong, G. B. Tran, Nam Le and Matt Huynh. Employing Espiritu’s method of ‘critical juxtapositioning’, I engage Édouard Glissant’s relationality of the abyss and the opacity of the open boat to contextualize forced migration narratives within a longue durée of imperialism that Aníbal Quijano calls coloniality. Ending with Long Bui’s discussion of a postmemory generation of Vietnamese diasporic artists and writers’ use of performativity, I show how they forward critical refugee studies when they imaginatively return to the journey, articulating relationalities that cross oceans and temporalities.
Material stories of migration: Reframing home through poetry
Authors: Barnsley Veronica , Bower Rachel , Teifouri Shirin
Published: January 2023

This article reflects on the power of poetry to reframe the concepts of home, arrival and belonging, each of which is important in understanding the relationship between migration and culture. It traces the journey of a collective poem – ‘Grapes in My Father’s Yard’ – that was created during the Material Stories of Migration project in Sheffield in 2015; was performed at Migration Matters Festival and has since been shared in multiple digital and material formats between 2015 and 2022. The text’s trajectory demonstrates poetry’s capacity to transgress structural and grammatical norms and capture that which is absent, ambiguous and elusive in the idea of ‘home’. The poem intertwines different languages and flows between them, enacting the give and take of linguistic and cultural translation. This article draws on follow-up interviews and ongoing discussion with project participants and creative facilitators to explore how the ‘storying’ of migrant lives is an ongoing creative process that poetry can illuminate. ‘Grapes in My Father’s Yard’ articulates how post-arrival life for migrants is not a linear, forward-moving process but a kind of re-dwelling in lost homes and landscapes, the beginning of a micro-bordering which continues for years. The poem calls on us to read between the lines and to seek out the silences, as much as it asks us to listen to the words.
Temporal statelessness and the oppressive liminality of perpetually unfulfilled hope: An examination of waiting in Basma Abdel Aziz’s The Queue
Authors: Ulmer Jasmine , Salvo y deLeón James M.
Published: January 2023

Narratives of migration can be without movement. When people are suddenly internally displaced, for example, they become non-citizens in their former home countries and are unable to move, much less leave. In instances such as these, we suggest that it may be a temporal – rather than spatial – displacement that has occurred. In so doing, we examine one aspect of temporal displacement: the perpetual state of waiting as a potential tool of bureaucratic control. This is a tool that operates along an axis of hope and anxiety in what may be an attempt to keep people exactly where they already are. This state of waiting appears throughout Al-Tabuur (The Queue), a translated and fictionalized novel written by Egyptian author Basma Abdel Aziz. As illustrated here, Aziz’s novel challenges notions that migration inherently involves progress, and instead shows what can happen when both time and movement seemingly come to a still.
Brexit, the pandemic and the battle with language: An interview with Daljit Nagra
Authors: Chambers Claire , Gilmour Rachael
Published: January 2023

This interview with the well-known poet Daljit Nagra was conducted in summer 2022 by Claire Chambers, with Rachael Gilmour providing questions in absentia due to a bout of coronavirus. In it, the three discuss such issues as ‘refugee tales’, poetic ethics and voice, the Brexit referendum’s emboldening of the far right and, of course, the COVID-19 pandemic. Above all, the conversation turns to Nagra’s bending of language via his use of ‘babu English’, his interpolation of Hindi and Punjabi words and his influences from such authors as William Shakespeare, John Milton and Nissim Ezekiel. Nagra looks in particular towards his fifth, forthcoming collection Indiom. In these ways, the interview develops on and updates interview with Nagra for Crossings and chapter on language and voice in Nagra’s first three collections.
Usability of Rice Straw as Biosorbent for the Removal of Phosphate from
Aqueous Solution: Isotherms, Kinetics and Thermodynamics
Authors: Ravina  , Yadav Sashi , Chhikara Sunil
Published: January 2023

The present study evaluated the adsorption of phosphate ions from an aqueous solution using rice
straw-based adsorbents. The batch study was performed to find the effect of pH, initial ion concentration,
a dose of adsorbent, contact time and temperature. The maximum adsorption capacity of raw and
modified rice straw is 6.47 mg/g and 16.60 mg/g. Both adsorbents (raw rice straw and modified rice
straw) showed good adsorption capacity at pH 8, adsorbent dose of 0.5 g for modified rice straw and
0.6 g for raw rice straw with an initial ion concentration of 20 ppm, contact time of 60 min at 100 rpm.
Adsorption isotherm, kinetics and thermodynamic studies were also performed for adsorption data.
The monolayer adsorption capacity was measured for raw rice straw at 6.21 mg/g and modified rice
straw at 6.36 mg/g. Freundlich isotherm (correlation coefficient 0.91 for raw rice straw and 0.96 for
modified rice straw) was best fitted to experimental data compared to Langmuir isotherm. The
pseudo-second-order showed a correlation coefficient of 0.99 for both adsorbents and was perfectly fit
to adsorption data. A thermodynamic adsorption study showed that the adsorption of phosphate ions
is endothermic and non-spontaneous at a lower temperature. The present study revealed that modified
rice straw adsorbent has good removal efficiency for phosphate ions.
A Changing Culture? An Exploration of Data Sharing in the Humanities
Authors: Grant Rebecca , Cannon Matt , McKellar Kate
Published: January 2023

This poster will present preliminary results from a survey of humanities authors, and interviews with editors of humanities journals, which aimed to explore their attitudes towards, and knowledge of research data sharing.

Although academic publishers are increasingly adopting data sharing policies across their journal portfolios, many policies are drafted to reflect scientific research outputs rather than those from the humanities or social sciences. Researchers in the humanities may find compliance with such policies challenging, and struggle to identify what constitutes their “research data” and how it can be shared appropriately.

As part of the STM Association’s Research Data Program, a group representing seven academic publishers (Taylor & Francis, SAGE, BRILL, Oxford University Press, Wiley, F1000 and Cambridge University Press) have come together to discuss how data sharing by authors in humanities journals can be supported and encouraged.

The group developed an online survey to identify which aspects of data policy compliance researchers find most challenging; and in parallel, conducted a series of interviews with editors to discuss the impacts of data sharing policies on their journals. The results presented will address questions including “What is humanities data?” and “Do humanities researchers perceive journal data sharing policies negatively, or positively?”
Inaccessible data sharing: Link rot in the Data Availability Statement
Authors: Jiao Chenyue
Published: January 2023

Data Availability Statement, an account within research articles about whether the data underlying the research is shared and if so, how it can be accessed, has been increasingly embraced by academic communities as a venue to share research data. The Public Library of Science (PLOS) is one of the first major publishers to implement this policy from the beginning of 2014 and reported that 20% of statements linking to external websites in 2016. However, does this policy greatly improve the availability of research data? Few studies have examined the effectiveness of these statements in data sharing. In this study, we examined to what extent the shared data can be accessed from the links specified in the statements. 39,444 URLs from all PLOS ONE publications between 2014 and 2020 were extracted. In this poster, we present preliminary findings on the types of URLs specified in the statements and their access rates. Our study aims to draw attention from data publishers and researchers on the issues of inaccessible data sharing and highlight the inconsistent practices of linking certain data repositories in the data availability statements. Finally, we propose three recommendations for those dedicated to data sharing and publishing to improve their data policy so as to promote the availability of datasets. The implications of our findings and the next step of the study are also discussed in this presentation.

With the explosion of video content, society and scholarly publishers need to make their videos searchable on platforms other than YouTube. Users are demanding it. By converting video to text and then indexing and semantically enriching the transcript with appropriate metadata change search to found. If your video content is not searchable, your clients are not finding the information they need at a moment’s notice. Researchers don’t have the time to watch an entire video anymore. They want to go to the specific location in the video where the topic of interest is discussed. Publishers are indexing and enriching all types of videos including lectures, presentations, training, and marketing videos. This poster will show you how this is done best.
AI and Peer Reviewer Selection
Authors: Selonick Lillian Wang , Gupta Saumya , Pajerowski Jennie
Published: January 2023

In a recent study by Hamilton (2020), of 196 surveyed journal editors, only 35% reported satisfaction with their journal’s peer review process. They named, among other challenges, difficulty recruiting reviewers as one desired area of improvement. Publishers, meanwhile, have shown an interest in diversifying their author, editor, and reviewer pools, as evidenced by the proliferation of webinars, committees, projects, and coalitions dedicated to increasing Diversity, Equity, and Inclusion—notably, C4DISC, the Royal Society of Chemistry’s Joint Commitment, last year’s Peer Review Week theme of Identity in Peer Review, and the many excellent posts on the Scholarly Kitchen that address this topic. In recent years, companies like Clarivate and Unsilo have introduced AI-driven tools that claim to meet the editors’ need by suggesting relevant reviewers. In this poster, we will explore the viability of using these and similar technologies to improve the diversity of reviewer pools by connecting editors with reviewers outside of their usual professional networks. These technologies are exciting, but have the potential to perpetuate existing biases. Artificial intelligence has the potential to improve the peer-review system; however, Checco et al. (2021) found major pitfalls and implications of using AI tools in terms of biases and ethics.

To what extent can technology counterbalance human bias by suggesting early career, non-male, or international reviewersü What biases might an AI-driven reviewer search replicate, and can they be avoidedü How do design choices by submission management systems affect an editor’s reviewer selection processü Are there problems that can’t be solved by techü
Smarter Business Intelligence for the Open Access Era: The Advanced Analytics You’re Probably Not Using for Your Editorial, Sales, and Plan S Strategies
Authors: Groth Mike , Beyer Tom , Maxwell Stuart
Published: January 2023

Beyond basic COUNTER compliance, many societies and independent publishers struggle to turn platform and usage analytics into action, especially for Open Access content. From measuring the performance of their publications to guiding editorial strategy to uncovering revenue opportunities, scholarly publishers often don’t avail themselves of all the measurable data or know how to use it to make informed business decisions. Add to that the problems of unauthenticated and unidentified OA usage, the indeterminate status of transformative journals, and the onerous reporting requirements of Plan S, and publishers can easily find themselves in a state of analysis paralysis.

Fortunately, there are many resources already at your disposal and supplemental supports to help academic book and journal publishers connect the dots, fill in the OA gaps, and make sense of raw data to turn it into actionable business intelligence. KGL PubFactory’s Tom Beyer will give an overview of publishing analytics from essential reports to advanced custom metrics using granular data, to emerging capabilities and prerequisites for tracking and reporting OA content. Joined by a publisher who will describe specific use cases, the authors will cover the latest advances in business analytics and unique data problems experienced by our industry. Together we will aim for a higher intelligence—no matter what business model—to better serve our users and the research community.

Published: January 2023

The objective of this study was to evaluate whether individuals with chronic renal failure (CRF) undergoing hemodialysis treatment have more salivary and oral mucosa alterations when compared to healthy individuals, through a systematic review followed by meta-analysis. A systematic literature review was performed, evaluating randomized clinical trials found in the Proquest, Embase, Scopus, Cochrane Library, Web of Science, Lilacs and Pubmed databases, using MeSH terms and other keywords. Initially, 40 articles were included in the study and, after reading the complete articles, only 15 clinical trials that analyzed oral lesions and salivary changes in patients with CRF undergoing hemodialysis treatment were eligible. Most of the clinical studies included were cross-sectional and composed of a study group and a control group. The mean age of participants in the study group was 50.19 years and in the control group, 48.95 years. The most common oral alterations found in the CRF group in relation to the control group were xerostomia, uremic breath, dysgeusia, coated tongue, gingival bleeding and pale mucosa. The salivary flow of patients with CRF was 46.6% lower than the control group. The salivary pH in the study group was also more alkaline when compared to the control group. Greater amounts of urea, phosphate, C-reactive protein and total proteins were found in the saliva of individuals with CRF. Individuals with CRF undergoing hemodialysis are more prone to changes in both the quantity and quality of saliva, as well as having a greater amount of oral changes.
Study on the Hydrophobicity and Antibacterial Activity of Silica Sol-Chitosan-HDTMS Treated Cotton Fabric Dipped in an Aquas Media
Authors: Das Prasanta , Roy Manas Datta , Ghosh Subrata
Published: January 2023

A hydrophobic surface with an antibacterial property has numerous uses, including self-cleaning, anti-sticking, anti-contamination, sports apparel, and wound healing/implant materials. The durability of the coating in an aquas media (pH 7.4) is a vital requirement for use in technical textile sectors, particularly in medical applications. In this study, we used silica sol, chitosan and hexadecyltrimethoxysilane (HDTMS) to create exceptionally hydrophobic surfaces with antibacterial properties on cotton fabrics. First, cotton fabric was treated with silica sol, which was produced by the hydrolysis and condensation of tetraethoxysilane (TEOS) in an alkaline environment. After that, chitosan was applied on the silica sol-treated fabric to add an antibacterial characteristic. The silica sol-chitosan-treated fabric was then given a hydrolysed HDTMS treatment to give a highly hydrophobic property. The hydrophobicity was assessed by measuring the water contact angle, while the AATCC-147 test protocol was used to assess the antibacterial property. The developed fabric exhibited a strong hydrophobic property. The fabric samples were immersed in an aquas media for 30 days to assess the coating durability by observing changes in hydrophobicity and anti-bacterial activity in terms of the zone of inhibition (ZOI). After 30 days of immersion in the aquas media, it was observed that the contact angle decreased from 151.7° to 129.5°, and the ZOI increased from 1 mm to 5 mm, which indicates an increase in anti-bacterial activity in relation to time of immersion. The wicking characteristics of coated and uncoated fabrics were also measured to determine how coating affects the wicking behaviour of fabric. EDS was performed to observe the coating stability for coated-dipped fabric samples after 30 days. SEM analysis was performed to examine the surface morphology, while FTIR was used to determine the surface functional groups after coating and changes after dipping in the aquas media. The developed hydrophobic cotton fabrics with anti-bacterial properties may help in the fabrication of natural biomaterials and other technical textile products.

Published: January 2023

This paper presents the theoretical and experimental investigation on performance of a photovoltaic (PV) panel cooled by porous media under indoor condition. Porous media offer a large exterior surface area and a high fluid permeability, making them ideal for PV cells cooling. The photovoltaic panel was cooled using 5 cm thick cooling channel filled with porous media (gravel). Several sizes of porosity (0.35, 0.4, 0.48, and 0.5) at different volume flow rates (1, 1.5, 2, 3, and 4 L/min) were tested to obtain the best cooling process. The theoretical analysis was performed at the optimum case found experimentally, which has a porosity of 0.35 and a volume flow rate of 2 L/min, to test various experimental results of the PV hot surface temperature, related power output, efficiency and I-V characteristic curve. The enhancement obtained in PV power output and efficiency is compared against the case without cooling and the case using water alone without porous media. Results showed that cooling using small size porous media and moderate flow rate is more efficient which reduces the average PV hot surface temperature of about 55.87% and increases the efficiency by 2.13% than uncooled PV. The optimum case reduced the PV hot surface temperature to 38.7°C, and increased the power output to 19 W, efficiency to 6.26%, and the open voltage to 22.77 V. The results showed that the presence of small porous media of 0.35 in the PV cooling process displayed the maximum effectiveness compared to the other two scenarios, because the heat loss from PV surface through porous media layer have developed a homogenous heat diffusion removed much quicker at high flow rate (2 L/min). A good agreement was obtained between experimental and theoretical results for different cases with a standard deviation from 3.2% to 5.6%.
Schwarz und Grau hinter Weiß und Rot. Autoritäre Potenziale in der türkischen und in der polnischen Gesellschaft im Spiegel der Reportagen Bittersüße Heimat: Bericht aus dem Inneren der Türkei von Necla Kelek und Rückkehr nach Polen: Expeditionen in mein Heimatland von Emilia Smechowski
Authors: Okoński Krzysztof
Published: January 2023

(Post-)Migrationsliteratur polnischer und türkischer Autoren in Deutschland ist nicht mehr eine künstlerische Aufarbeitung des Lebens in der Fremde, ein Blick auf den Westen aus östlicher Perspektive oder ein Spiegelbild von Traumata, Phobien und Träumen aus der alten Heimat. Schriftsteller mit ausländischen Wurzeln beziehen sich in ihren Werken immer häufiger auf die deutsche Geschichte und Gegenwart. Ähnlich wie die Autoren türkischer Herkunft, berichten auch die in Deutschland lebenden polnischen Schriftsteller und Publizisten über das Land ihrer Kindheit – und das ist nicht immer ein sentimentaler Blick. Ideologische Polarisierung, antidemokratische Tendenzen, Patriarchat, religiöser Radikalismus, Phantomschmerzen und Sehnsucht nach der imperialen Vergangenheit, Nationalismus und Idealisierung der eigenen Geschichte, Teilung des Landes in prowestliche Metropolen und in eine konservative Provinz bilden einen Hintergrund für die Wanderung durch das wiederentdeckte Herkunftsland – in Polen und in der Türkei. Emilia Smechowskis Rückkehr nach Polen. Expeditionen in mein Heimatland (2019) und die Reportage der deutsch-türkischen Soziologin Necla Kelek Bittersüße Heimat: Bericht aus dem Inneren der Türkei (2008) bilden den Ausgangspunkt für eine vergleichende Analyse der autoritären Potentiale in beiden Gesellschaften.

Migracja jest jednym z bardziej doniosłych doświadczeń egzystencjalnych współczesnego człowieka. Jest to zmiana, która pociąga za sobą poważne konsekwencje dla jednostki, niezależnie od tego, czy towarzyszą jej motywacje o charakterze przymusu (politycznego bądź ekonomicznego), czy też mamy do czynienia z migracją dobrowolną. W obu tych przypadkach proces adaptacji w nowym miejscu może okazać się zadaniem niełatwym i obciążającym dla jednostki. Co więcej, może on rzutować również na kolejne pokolenia. Dzieci migrantów niejednokrotnie zmagają się bowiem z tymi samymi problemami, którym czoła musieli stawić ich rodzice bądź dziadkowie. O tym, że funkcjonowanie między dwoma kulturami, językami, tradycjami może okazać się literacko płodne, świadczy twórczość pisarzy o korzeniach węgierskich, którzy mieszkają i tworzą poza krajem swojego pochodzenia. Niniejszy artykuł analizuje twórczość trzech takich autorek: Terézii Mory i Ilmy Rakusy, które piszą po niemiecku, oraz anglofońskiej autorki Charlotte Mendelson. Każda z nich tematyzuje zagadnienie migracji w inny sposób i posługuje się innymi rozwiązaniami na poziomie struktury i narracji utworów.
Podbój stron rodzinnnych Sinišy Kovačevicia, czyli serbska opowieść o powojennym przesiedleniu
Authors: Giergiel Sabina
Published: January 2023

Punktem wyjścia tekstu jest wskazanie na popularność dramatu Sinišy Kovačevicia pt. Velika drama (Wielki dramat) w Serbii. Dramat ten w 2019 roku ukazał się formie powieściowej (saga rodzinna). Jej tematem jest migracja rodziny Vučiciów z niedostępnej i górzystej Czarnogóry na terytorium Kotliny Panońskiej. Kovačević – w dość schematycznym pod względem fabularnym i ideowym utworze – wskazał, że powojenny transfer ludności wiązał się z przybywaniem do znacznie bardziej rozwiniętej gospodarczo i kulturalnie Wojwodiny „nowego człowieka” (reprezentanta tradycyjnej cywilizacji wiejskiej). W artykule szczególny nacisk położony zostanie na obraz Czarnogóry i Wojwodiny wyłaniający się z kart powieści. Kovačević bowiem oba regiony wyraźnie aksjologicznie waloryzuje. Czarnogóra jest ostoją dawnych, prawdziwych wartości. Wojwodina symbolizuje zaś to, co obce. Na tę opozycję nakłada się ponadto przeciwstawienie starości (kojarzonej z mądrością i tradycją) i młodości (utożsamianej z naiwnością i idealizmem).
Reakcja polskich wydawców dla dzieci na kryzys azylowy (2015–2022)
Authors: Bednarek Magdalena
Published: January 2023

Od 2016 roku na polskim rynku wydawniczym dla dzieci pojawiło 26 tytułów dotyczących przymusowych migrantów. Ich obecność powiązana jest ściśle z narastającym od 2015 roku kryzysem polityki migracyjnej w Europie, który na przestrzeni minionych lat coraz mocniej dotykał Polskę. Kolejne fazy kryzysu azylowego wyznaczonego przez kryzys na granicy polsko-białoruskiej (2019) oraz wojnę w Ukrainie (2022) wywoływały różne reakcje wydawców dla dzieci. Celem artykułu jest zbadanie związku między dominującym dyskursem nt. uchodźców, dystansem przestrzennym od kryzysu oraz dystansem kulturowym od przymusowych migrantów a aktywnością wydawców dla dzieci w zakresie publikacji książek dotyczących kryzysu azylowego. Analiza segmentu rynku dla dzieci w latach 2015–2022 uwzględniająca wymienione parametry prowadzi do wniosku, że książka dla dzieci jest przestrzenią intensywnego napięcia ideologicznego, przebiegającego na linii między wielkimi i małymi wydawnictwami.
Pierwsza i ostatnia emigracja. Próba porównania.
Authors: Dąbrowski Mieczysław
Published: January 2023

Artykuł jest próbą opisu i porównania pierwszej fali emigracji zarobkowej z końca XIX wieku i podobnej do niej drugiej fali z końca XX wieku, wzmocnionej w 2004 roku przystąpieniem Polski do Unii Europejskiej oraz wskazania różnic i podobieństw między nimi. Pierwsza fala została opisana przez ważnych pisarzy pozytywistycznych, druga przez samą siebie. Na podstawie tych tekstów autor bada takie kategorie, jak patriotyzm, ksenofobia, religijność, obyczajowość, język itp.
Foreign language teacher grit: scale development and examining the relations with emotions and burnout using relative weight analysis
Authors: Soleimanzadeh Soheila , Khajavy Gholam Hassan , Barabadi Elyas
Published: January 2023

As teaching a foreign language (FL) is a demanding and frustrating career, FL teachers might face different challenges and difficulties which in turn would lead them to quit their jobs. Therefore, FL teachers need to keep their effort, energy, and passion to achieve their teaching goals. FL teacher grit (i.e., perseverance of effort and consistency of interest in FL teaching) is the concept that deals with these issues. In this study, we developed a new FL teacher grit scale (FLTGS) and investigated how FL teacher grit is related to their burnout and different discrete emotions. To this end, a total of 235 FL teachers filled out the questionnaires. The results of the study indicated, firstly, that the newly developed FL teacher grit scale had high reliability and a two-factor model fitted the data adequately. Secondly, findings indicated that both grit components had positive correlations with FL teaching enjoyment and negative correlations with FL teaching anxiety, boredom, and burnout. Finally, the results of relative weight analysis showed that FL teacher grit components can be as important as emotions in predicting burnout. Our findings suggested that the newly developed grit scale could provide us with a valid and reliable tool to assess FL teacher grit. Moreover, our findings suggested that higher levels of FL teacher grit can prevent them from experiencing burnout.

The absorption, distribution, and transport trends of organic and inorganic arsenic (As) in honesuckle (Lonicera japonica) were studied using synchrotron X-ray fluorescence spectroscopy (μ-XRF). The root, stem, and leaf samples were analyzed by μ-XRF, proving that in the presence of dimethyl arsenate acid, a small amount of As accumulated in local areas of the epidermis and cortex of roots, while most of As migrated to the upper plant through the middle vascular column. After reaching the stem, As was mainly distributed in the outer skin, indicating that the root and stem of L. japonica blocked the transport of As in the plant. In the presence of As(iii), A large amount of As accumulated in the epidermis and cortex of the root, reducing its further transport from the plant roots. Once As entered the stem of L. japonica from the root, it achieved a strong transport capacity, thus causing severe harm to plants. The element correlation analysis revealed that As in L. japonica had the strongest correlation with Cu and Zn elements, for the future research on the influence of As pollution on plants, the interference based on the above two elements can be considered.

Insight into the mechanism underlying modification of Neosinocalamus affinis by hygrothermal treatment
Authors: Feng Qiming , Huang Yanhui , Zhao Rongjun , Fei Benhua
Published: January 2023

Hygrothermal treatment is an effective method for improving the dimensional stability of bamboo. In this study, changes in the physicochemical properties of Neosinocalamus affinis after hygrothermal treatment were comprehensively investigated: the hemicellulose content decreased, C=O in the acetyl group and the hydroxyl content decreased and xylan was partially degraded. The dimensional stability of N. affinis gradually increased with temperature, and optimal values were obtained at 220 °C, as indicated by a 16.5% decrease in anti-swelling efficiency and a 93.7% increase in contact angle. Alterations in the macromolecular structure of lignin were also observed: the contents of β-O-4 linkages and p-coumarate decreased by 54.3% and 23.9%, respectively; β-5 linkages disappeared at 220 °C, as determined by heteronuclear single quantum correlation spectroscopy. However, the maximum values for crystallinity, nano indentation elastic modulus, and hardness were reached at 180 °C and were higher than those of the untreated samples by 8.6%, 19.9%, and 23.5%, respectively. With the combined application of physical mechanics and dimensional stability, hygrothermal treatment at 180 °C and 100% relative humidity was proved to exert the optimal effects on N. affinis. These results provide new and comprehensive insights into the mechanism allowing the modification of N. affinis by hygrothermal treatment.
