Authors: Ahmed Syeda Hafsah , Raza Mehwish , Kazmi Majida , Mehdi Syeda Shajeeha , Rehman Inshal , Qazi Saad Ahmed
Published: July 2023

Modern development in deep learning and computer vision techniques, intelligent transportation system (ITS) has emerged as a useful tool for building a traffic infrastructure in smart cities. Previously, several computer vision techniques have been proposed for vehicle recognition, which were limited in handling undisciplined, dense and laneless traffic conditions. Moreover, these frameworks did not incorporate many of the local vehicle configurations common in South Asian countries such as Pakistan, Bangladesh, and India. Considering the limitations of previous frameworks, this paper presents efficient vehicle detection and counting model for undisciplined conditions including dense and laneless traffic, occulusion cases and diverse range of local vehicles. A dataset of more than 2400 images of vehicles has been collected comprising of six new categories of local vehicles, and considering undisciplined traffic conditions to ensure robustness in vehicle detection and counting system. Transfer learning based technique has been used, using faster R-CNN model with Inception V2 as underlying architecture. The experimental results show a precision of 86.14% in terms of mAP. The work finds its application in South Asian contexts as more smart cities are formed in this region. The proposed framework will enable traffic monitoring with higher reliability, accuracy and granularity, contributing in having next-generation ITS.

Published: July 2023

In order to solve the problem of frequent drug dosing and increase its effectiveness, theophylline (THP) was deposited on chitosan nanoparticles (CSNPs). THP-CSNPs nanocomposites with the composition of 50, 75, 100 or 150 mg of chitosan (CS) and 25, 50, 75, 100 or 200 mg of tripolyphosphate (TPP) at pH 4.0, 5.0, 6.0 and 6.5 were prepared, and a constant weight of THP of 100 mg. The nanocomposites were characterized by X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), and Fourier transform infrared spectroscopy (FTIR). The rate of drug release was also tested. The Minitab 18 program was used to analyze the results. The independent variables were the CS, TPP, and pH, while loading efficiency, zeta potential, and particle size were the dependent variables. The nanocomposites successfully transported and protected the drug, providing its sustained release.
Problematising the South African Higher Education inequalities exposed during the Covid-19 pandemic: Students’ perspectives
Authors:   Rhodes University, Knowles Corinne , James Abongile , Khoza Lebogang , Mtwa Zikhona , Roboji Milisa , Shivambu Matimu
Published: July 2023

Former Rhodes University students, co-authors of this article, were engaged in a knowledge-making project during the Covid-19 pandemic. This paper is a product of that project, where participants deliberated on the inequalities in the education sector based on their experiences in their university. These were exposed and exacerbated by the pandemic. Using a decolonial theoretical lens, they present the experiences of students to critique university decisions at the time. They argue for a reconnection with the idea of the university as a public good, as an antidote to the neoliberal tendencies that perpetuate inequality in the sector. This requires a reconnection with its own students, and to collaborate with them to find strategies to deal with crises such as the Covid-19 pandemic. Additionally, a reconnection between the university and the school sector could lead to greater synergy and an easier transition between school and university.
How did Markets and Public Sentiment React During Demonetization? Study of a Significant Event in the Indian Economy
Authors: Sinha Manish , Sharma Dipasha , Sheorey Pratima Amol
Published: July 2023

The present study aims to determine the impact of shock of demonetization which happened in November 2016 in India. It has been observed in literature that while the market moves due to unforeseen events, market movements are largely affected by news reports on such events. Considering these two threads and the association between them, the study follows mixed method research methodology and assesses the impact of demonetization on stock market movement through time series analysis and text analytics of news items generated during the period. This study examines, through time series analysis, the impact of demonetization as an unexpected event on stock market movement. Time series analysis evaluates the impact on overall stock market movements and on sectoral indices, liquidity shocks in the emerging Indian economy due to demonetization. This study integrates time series analysis with robustness tests and follows text analytics, news analytics and sentiment analytics to gauge public sentiment (influenced by media coverage) during the event. These evaluations validate negative movements in the market and most of the sectors due to the negative sentiment of people about demonetization.

Published: July 2023

Hancornia speciosa Gomes belongs to the family Apocynaceae and is distributed across different regions of Brazil. The objective of this study was to evaluate callus induction and histodifferentiation in five mangaba accessions under different in vitro culture conditions. Five acessions from the Active Germplasm Bank of Mangaba (Embrapa, Brazil) were evaluated. In vitro-germinated plant seedlings were used for the excision of different explants (internode and node segments, and foliar section). These segments were inoculated in a culture medium containing different concentrations of 6-Benzylaminopurine (BA) and 2,4-Dichlorophenoxyacetic acid (2,4-D). There was a significant effect of accessions, treatments, and time on the callus mass (g). There was no callus induction in the absence of regulators. After 60 days of in vitro culture, all treatments exhibited a linear positive cellular growth. The highest callus mass was observed in the BI accession, in the presence of 22.62 µM 2,4-D and 11.10 µM BA.

Artikel ini didasarkan pada hasil pengabdian kepada masyarakat yang bertema pengembangan Badan Usaha Milik Desa (BUMDes) Maju Mandiri, di Desa Candi, Kecamatan Bandungan, Kabupaten Semarang yang berbasis pada Tujuan Pembangunan Berkelanjutan Poin satu tentang Pengentasan Kemiskinan. Dibandingkan dengan potensi pengembangan ekonomi yang dimiliki oleh Desa Candi yang luar biasa seperti dalam sektor pariwisata, peternakan, pertanian, serta Usaha Mikro Kecil dan Menengah (UMKM), BUMDes di Desa Candi kurang begitu berkembang. Hal ini terlihat dalam sedikitnya unit usaha yang berjalan, serta pengelolaan yang kurang efektif, terutama pasca-pandemi COVID-19. Pengabdian kepada masyarakat ini bertujuan untuk merumuskan peta jalan pengembangan BUMDes dengan memanfaatkan peluang-peluang yang ada di Desa Candi, melalui penyusunan dokumen Desain Strategi dan Rencana Aksi (DSRA) yang disusun secara partisipatif dengan pemangku kepentingan BUMDes. Hasil pengabdian ini menunjukkan bahwa ada tiga komponen penting yang perlu dikembangkan untuk meningkatkan kinerja BUMDes, yakni sumber daya manusia, unit bisnis, dan kerjasama multipihak.
Building A Rural Economic Area Through Cooperation Between Villages: A Case Study of Agrotourism-Based Rural Area Development in Banyumas, Indonesia
Authors: Harsanto Bambang Tri , Isna Alizar , Wahyuningrat Wahyuningrat , Tobirin Tobirin , Indiahono Dwiyanto
Published: July 2023

This study aims to evaluate the implementation of cooperation between villages based on agrotourism in the Kendeng Mountains, Somagede District, Banyumas Regency as a model for developing rural areas in Banyumas Regency. The research was conducted in three villages in Somagede District, i.e., Tanggeran, Klinting, and Kemawi, and served as a pilot project for rural area development. Qualitative method is conducted through meetings with informants from all village officials and tourism business actors in the three collaborating villages and members of the Rural Area Development Coordination Team. This study employs qualitative method utilizing in-depth interviews, observations, documentation, and focus group discussion (FGD), while the findings were analyzed using an interactive analysis model. The results showed that the cooperation between the villages of Kemawi, Klinting, and Tanggeran in developing agrotourism-based rural areas did not yield the expected results. The failure is due to the absence of cooperation norms among members, the identification of common needs that must be resolved through inter-village collaboration, and the low commitment of the village heads to prioritize and carry out all program plans. The cooperation also fails because of the lack of support from the local government during program implementation and the absence of monitoring and evaluation activities at each stage of the implementation of inter-village cooperation.

Productive efficiency of Premier League teams using an enhanced data envelopment analysis approach
Authors: Šíma Jan , Voráček Josef , Kraft Jiří , Krause Veronika
Published: July 2023

The study focuses on evaluating the economic efficiency of professional football clubs. It builds on the Haas Study, which examines the effectiveness of individual clubs through Data Envelopment Analysis (DEA). DEA analyses different types of inputs and outputs for homogeneous production units (in this case football clubs). The thesis proposes the modification of this model. The author considers the initial “hometown population” contribution of Haas as particularly outdated with regard to the increasing commercialisation of professional football and globalisation of the market, where the size of demand is primarily determined by the global popularity measured in terms of interest of the fans, sponsors, and television broadcasting companies. The global popularity of the club can easily be estimated at present using the number of fans in social networks. The clubs reflect this target on the side of the outputs – “increase of the number of fans in the social network”. Facebook was chosen as the representative of the social networks. The proposed model is used in the paper for calculation of the economic efficiency of the participants in the English Premier League in the 2016–2017 season.
Managerial roles and their application in non-profit sports organisations
Authors: Voráček Josef , Čáslavová Eva , Kraft Jiří
Published: July 2023

This article focuses on leadership and the role of managers in the field of non-profit sports organisations, knowing that this area of activity is still largely neglected by research. The main goal of this research was to find out what roles managers currently play in the management of non-profit organisations in the field of sports. The method of a quantitative questionnaire survey was applied and the respondents were 270 non-profit sports organisation managers. The research shows that the roles of managers of non-profit sports organisations have significantly affected interpersonal activities to fulfil the mission of these organisations more than to strengthen their economic performance. The overshadowing of some managerial roles creates an incentive to focus on the creation of educational offers aimed at strengthening leadership, management of subsidies from public sources, and the possibility of using marketing in the field of creating their own financial resources.
Gameplayowe transgresje w grach cyfrowych
Authors: Kochanowicz Rafał
Published: July 2023

The latest and increasingly sophisticated digital simulations, often set in fantastical worlds, have become like laboratories in which players/ audiences can test their knowledge of culture, their ethical beliefs, interpretive skills, and anthropological imaginations. The article looks at games not just through the lens of their programmed poetics, but rather as laboratories in which experimentation becomes one of the elements of play, and gameplay touches the essence of the game – the activity, which is defined as dynamic competition within an adopted convention. One example of such experimentation is the transgressive way of conducting gameplay. However, creating a detailed typology of all possible transgressive gameplay is clearly not feasible, especially when taking into account accidental situations, such as when a player exploits a loophole or error in the programmed process without realizing that they are intentionally bypassing solutions designed by the creators. Nonetheless, intentional actions can be characterized in terms of three basic aspects – ingression (e.g., interference with computer programs), progression (e.g., fastrun, bypassing, etc.), and regression (transpositions, refunctionalizations, etc.). They concern both evidence of specific intentions and reveal ways of breaking rules, introducing one’s own rules, or forcing one’s own gameplay style.
Odpowiedzialność odszkodowawcza prowadzących na własny rachunek przedsiębiorstwa lub zakłady wytwarzające środki wybuchowe albo posługujące się takimi środkami (art. 435 § 2 k.c.)
Authors: Moska Monika
Published: July 2023

Tytułowa tematyka nie doczekała się w polskiej literaturze szerszego opracowania, co stanowiło przesłankę podjęcia badań w tej materii. Celem artykułu jest dokonanie pogłębionej wykładni art. 435 § 2 k.c., regulującego odpowiedzialność prowadzących na własny rachunek przedsiębiorstwa lub zakłady wytwarzające środki wybuchowe albo posługujące się takimi środkami. Analizie poddano zwłaszcza zagadnienia podmiotu odpowiedzialnego za szkodę oraz zdarzenia szkodzącego, jak również pojęcie środków wybuchowych. W badaniach wykorzystano metodę dogmatycznoprawną. Interpretacja tekstu prawnego została dokonana przede wszystkim przy odwołaniu się do derywacyjnej koncepcji wykładni. Z podjętych rozważań wynikają w szczególności następujące wnioski: podmiotem odpowiedzialnym za szkodę na gruncie art. 435 § 2 k.c. jest prowadzący na własny rachunek przedsiębiorstwo lub zakład wytwarzający środki wybuchowe lub posługujący się nimi, przy czym przez „środki wybuchowe” należy rozumieć substancje chemiczne, które samorzutnie lub pod wpływem określonego oddziaływania zewnętrznego zdolne są do gwałtownej przemiany chemicznej o charakterze egzotermicznym, której towarzyszy wydzielanie produktów gazowych w postaci wybuchu, przez co mogą one powodować zniszczenia w otaczającym środowisku. Wątpliwości w zakresie tego, czy dany podmiot jest adresatem normy wynikającej z interpretowanego przepisu powinny być rozstrzygane z uwzględnieniem stopnia niebezpieczeństwa przez niego generowanego. Omawiana odpowiedzialność powstaje tylko wówczas, gdy szkoda pozostaje w związku z wytwarzaniem środków wybuchowych lub posługiwaniem się nimi.
Socjologia wobec design thinking
Authors: Afeltowicz Łukasz , Rudnicki Seweryn
Published: July 2023

Design thinking (DT, myślenie projektowe) pojawia się dziś w wielu kontekstach – od biznesu, przez edukację, po innowacje społeczne – jako atrakcyjna metoda rozwiązywania szerokiego zakresu problemów. Jednak mimo jego popularności oraz faktu, że podejście to wykorzystuje pojęcia i metody badawcze zapożyczone z socjologii i innych nauk społecznych, zaskakująco mało uwagi poświęca się mu w refleksji socjologicznej. Celem tego artykułu jest uzupełnienie tej luki nie tylko przez omówienie głównych założeń podejścia design thinking, ale przede wszystkim przez dokonanie jego socjologicznej krytyki oraz przedstawienie możliwych wariantów reakcji socjologii jako dyscypliny na popularność tego podejścia. Artykuł ma charakter dyskusyjny i jest inspirowany badaniami z zakresu studiów nad nauką i technologią (STS), podejściem krytycznym w socjologii oraz koncepcją pola instytucjonalnego Pierre’a Bourdieu. Wyniki przedstawionej analizy pokazują, w jakim sensie design thinking może być atrakcyjne dla socjologii jako dyscypliny – nie tylko jako pewien zbiór narzędzi, ale jako odmienna, a przy tym inspirująca perspektywa poznawcza (akceptująca prowizoryczność i pragmatyzm), realizująca w pewnym stopniu program socjologii syntetycznej. Jednocześnie artykuł pokazuje, że podejście to jest podatne na krytykę jako operujące uproszczonymi założeniami, solucjonistyczne i uwikłane w społeczno-ekonomiczne zależności.
Frontier spirit and the making of the Japanese pioneer
Authors: Scherer Anke
Published: July 2023

This article analyses the origins of the so-called frontier spirit as the main feature of the Japanese pioneers who were the grass-roots agents of Japanese expansion into Asia. It argues that this narrative traces back to the government-sponsored cultivation program in Hokkaidō, where so-called tondenhei were employed as farmer-soldiers to open up the new frontier region as Japan’s first colony. After the termination of the tondenhei program, the frontier spirit took on a life of its own. It was embraced by advocates of Japanese settler colonialism on the Asian continent as a vital element of the quintessential Japanese pioneer, capable of overcoming any hardships that might arise. Consequently, the iconic Japanese pioneer in Manchuria, who eventually fell victim to Japan’s megalomanic migration machine in Northeast China, can be seen as the reincarnation of their equally unfortunate predecessor, the tondenhei soldier.
Thermal response of double network hydrogels with varied composition
Authors: Hanyková Lenka , Krakovský Ivan , Šťastná Julie , Ivaniuzhenkov Vladislav , Labuta Jan
Published: July 2023

The series of double network (DN) hydrogels, based on poly(N,N′-diethylacrylamide) (PDEAAm), polyacrylamide (PAAm), or poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPS) were synthesized with various mass ratios of components and their thermal response was investigated. The formation of DN structure in studied hydrogels results in significant increase in Young’s modulus. PDEAAm/PAMPS hydrogels exhibited rather high swelling ratio and consequently their temperature sensitivity was not detected. DN hydrogels PDEAAm/PAAm and PDEAAm/PDEAAm displayed thermo-responsive behavior, and the dependence of transition parameters on the feed molar concentration of acrylamide and N,N′-diethylacrylamide monomers, respectively, was determined through deswelling, NMR, and Differential scanning calorimetry (DSC) experiments. A two-state process model was employed to describe the phase transition of hydrogels. By utilizing a modified van’t Hoff equation with data from deswelling, NMR, and DSC experiments, we were able to obtain thermodynamic parameters of the transition and determine the size of the cooperative domains consisting of polymer units and water molecules.
A lexical-cognitive approach to the consequences of the coronavirus crisis for the emotions and perceptions of the Spanish population aged 65 and over
Authors: Ávila-Muñoz Antonio M.
Published: July 2023

The COVID-19 pandemic has devastated health systems, economies, and societies. Considered a high-risk group, the elderly have been amongst the most affected. Using word association tests, we access the perceptions held by a group of individuals aged 65 and over, pre-stratified by gender and level of education, regarding certain aspects of the situation we now face. We interpret the vocabulary provided during the tests as a network of connections. Thus, we can create the metastructure of the mental lexicon and consider it the reflection of the collective perceptions associated with five cognitive categories: pandemic, old age, society, future, and politics. For this, we use a model that allows us to construct cognitive prototypes based on the theory of fuzzy sets. Previous results warn of the emotional consequences that have affected the entire population. However, we are now also able to prove that the older generation is experiencing unprecedented feelings of loneliness and neglect due to the circumstances. This could exacerbate the worry, fear, and uncertainty imposed on this group by the new normal. Finally, we suggest concrete actions for both health workers in contact with groups of elderly individuals and the research community that generally uses attitudinal surveys.
Bayesian estimation and prediction for network meta-analysis with contrast-based approach
Authors: Noma Hisashi
Published: July 2023

Network meta-analysis is gaining prominence in clinical epidemiology and health technology assessments that enable comprehensive assessment of comparative effectiveness for multiple available treatments. In network meta-analysis, Bayesian methods have been one of the standard approaches for the arm-based approach and are widely applied in practical data analyses. Also, for most cases in these applications, proper noninformative priors are adopted, which does not incorporate subjective prior knowledge into the analyses, and reference Bayesian analyses are major choices. In this article, we provide generic Bayesian analysis methods for the contrast-based approach of network meta-analysis, where the generic Bayesian methods can treat proper and improper prior distributions. The proposed methods enable direct sampling from the posterior and posterior predictive distributions without formal iterative computations such as Markov chain Monte Carlo, and technical convergence checks are not required. In addition, representative noninformative priors that can be treated in the proposed framework involving the Jeffreys prior are provided. We also provide an easy-to-handle R statistical package, BANMA, to implement these Bayesian analyses via simple commands. The proposed Bayesian methods are illustrated using various noninformative priors through applications to two real network meta-analyses.

Evaluation of oxidative stress biomarkers together with myeloperoxidase/paraoxonase-1 and myeloperoxidase/high density lipoprotein cholesterol in ST-elevation myocardial infarction
Authors: Hamamcioglu Ayse Ceylan , Kalayci Belma , Kalayci Suleyman
Published: July 2023

Objectives

Oxidative stress is closely associated with atherosclerosis and acute coronary syndromes. The purpose of this study was to evaluate well-known and proportional oxidative stress biomarkers in ST-Elevation Myocardial Infarction (STEMI) patients.

Methods

In this single center, prospective and cross-sectional study, 107 individuals (63 patients) were studied. Total oxidative status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), ischemia modified albumin (IMA), myeloperoxidase (MPO), paraoxonase-1 (PON-1) and arylesterase (AREase) enzyme activities as well as MPO/PON-1, MPO/AREase and MPO/HDL-C ratios were studied. As short-term in-hospital prognosis biomarkers; in-hospital mortality, early systolic dysfunction and spontaneous complete revascularization were investigated.

Results

Our results indicated that TOS, OSI, IMA, MPO, MPO/PON-1 and MPO/HDL ratios were significantly higher, PON-1 and AREase were significantly lower in STEMI patients compared to the control group. However, in the regression analysis performed by adjusting the differences between the groups, only IMA was found as an independent risk factor (OR=2.711, 95 % CI=1.094–6.719, p=0.031). In terms of in-hospital short-term prognostic biomarkers, a significant relationship was found only between OSI and spontaneous complete revascularization. The OSI value was higher in the group with TIMI grade 3 flow than in the group with TIMI grade 0–2 flow (2.42 [0.81–4.49] vs. 1.63 [0.33–6.07], p=0.016).

Conclusions

In STEMI patients, both the well-known (TOS, OSI, and MPO) and proportional (MPO/PON-1 and MPO/HDL cholesterol ratios) oxidative stress markers were elevated and can be considered as having a role in the pathogenesis of STEMI.
Some versions of Chaplygin gas model in modified gravity framework and validity of generalized second law of thermodynamics
Authors: Sultana Sanjeeda , Güdekli Ertan , Chattopadhyay Surajit
Published: July 2023

In the work reported in this paper, we have analyzed generalized Chaplygin gas (GCG) and modified generalized Chaplygin gas (MGCG) in an interacting scenario. The equation of state parameter has been analyzed in both the cases and the stability of the models has been discerned through squared speed of sound. Stability against gravitational perturbations has been observed for both GCG and MGCG interacting with pressureless dark matter. Also, the generalized second law (GSL) of thermodynamics has been tested for different enveloping horizons and validity of GSL has been observed throughout. Furthermore, f(T) gravity has been reconstructed with GCG and MGCG and phantom behaviour has been observed through reconstructed EoS parameters. The squared speed of sound has been derived for f(T) gravity and stability of the model has been established through its positivity.
Anti-SARS-CoV-2 in vitro potential of castor oil plant (Ricinus communis) leaf extract: in-silico virtual evidence

Published: July 2023

Ricinus communis L. is a medicinal plant that displays valuable pharmacological properties, including antioxidant, antimicrobial, analgesic, antibacterial, antiviral and anti-inflammatory properties. This study targeted to isolate and identify some constituents of R. communis leaves using ultra-performance liquid chromatography coupled with mass spectroscopy (UPLC-MS/MS) and different chromatographic techniques. In vitro anti-MERS and anti-SARS-CoV-2 activity for different fractions and for two pure isolated compounds, lupeol (RS) and ricinine (RS1) were evaluated using a plaque reduction assay with three different mechanisms and IC50 based on their cytotoxic concentration (CC50) from an MTT assay using Vero E6 cell line. Isolated phytoconstituents and remdesivir are assessed for in-silico anti-COVID-19 activity using molecular docking tools. The methylene chloride extract showed pronounced virucidal activity against SARS-CoV-2 (IC50 = 1.76 μg/ml). It was also shown that ricinine had superior potential activity against SARS-CoV-2, (IC50 = 2.5 μg/ml). Lupeol displayed the most potency against MERS, (IC50 = 5.28 μg/ml). Ricinine appeared to be the most biologically active compound. The study showed that R. communis and its isolated compounds have potential natural virucidal activity against SARS-COV-2; however, additional exploration is necessary and study for their in vivo activity.

In this paper, Cr2O3-25TiO2 composite coatings were prepared on the surface of steel structure samples by atmospheric plasma spraying. The phase composition, microstructure, microhardness and long-term immersion corrosion behavior in 3.5 wt.% NaCl solution of Cr2O3-25TiO2 composite coatings were studied. The corrosion behavior of Cr2O3-25TiO2 composite coating was analyzed by potentiodynamic polarization and electrochemical impedance spectroscopy. The impedance data were fitted into an appropriate equivalent circuit to explain the electrochemical corrosion behavior of the coating at different stages. The results of scanning electron microscopy showed that the Cr2O3-25TiO2 composite coating was agglomerated, and the rhombohedral Cr2O3 powder was wrapped around the rhombohedral TiO2 powder. The coating melted completely without obvious defected. The XRD results showed that no phase transformation occurred in the Cr2O3-25TiO2 composite coating. The Cr2O3-25TiO2 coatings showed high corrosion resistance and good passivation behavior in the initial stage of corrosion. The coating itself did not corrode. With the extension of corrosion time, the corrosive medium had passed through the pores between the coatings, resulting in the contact between the corrosive medium and the matrix interface, resulting in the matrix corrosion damage. Corrosion products would deposit on the surface of the coating, blocking the pores between the coatings, and the corrosion rate would be reduced.

Published: July 2023

The centrosome linker joins the two interphase centrosomes of a cell into one microtubule organizing center. Despite increasing knowledge on linker components, linker diversity in different cell types and their role in cells with supernumerary centrosomes remained unexplored. Here, we identified Ninein as a C‐Nap1‐anchored centrosome linker component that provides linker function in RPE1 cells while in HCT116 and U2OS cells, Ninein and Rootletin link centrosomes together. In interphase, overamplified centrosomes use the linker for centrosome clustering, where Rootletin gains centrosome linker function in RPE1 cells. Surprisingly, in cells with centrosome overamplification, C‐Nap1 loss prolongs metaphase through persistent activation of the spindle assembly checkpoint indicated by BUB1 and MAD1 accumulation at kinetochores. In cells lacking C‐Nap1, the reduction of microtubule nucleation at centrosomes and the delay in nuclear envelop rupture in prophase probably cause mitotic defects like multipolar spindle formation and chromosome mis‐segregation. These defects are enhanced when the kinesin HSET, which normally clusters multiple centrosomes in mitosis, is partially inhibited indicating a functional interplay between C‐Nap1 and centrosome clustering in mitosis.

N6‐methyldeoxyadenosine (6mA) is a chemical alteration of DNA, observed across all realms of life. Although the functions of 6mA are well understood in bacteria and protists, its roles in animal genomes have been controversial. We show that 6mA randomly accumulates in early embryos of the cnidarian Hydractinia symbiolongicarpus, with a peak at the 16‐cell stage followed by clearance to background levels two cell cycles later, at the 64‐cell stage—the embryonic stage at which zygotic genome activation occurs in this animal. Knocking down Alkbh1, a putative initiator of animal 6mA clearance, resulted in higher levels of 6mA at the 64‐cell stage and a delay in the initiation of zygotic transcription. Our data are consistent with 6mA originating from recycled nucleotides of degraded m6A‐marked maternal RNA postfertilization. Therefore, while 6mA does not function as an epigenetic mark in Hydractinia, its random incorporation into the early embryonic genome inhibits transcription. In turn, Alkbh1 functions as a genomic 6mA “cleaner,” facilitating timely zygotic genome activation. Given the random nature of genomic 6mA accumulation and its ability to interfere with gene expression, defects in 6mA clearance may represent a hitherto unknown cause of various pathologies.
Taguchi Optimization of Geometrical Factors of a Polymer Composite Patch in Crack Repair

Published: July 2023

For the repair of a crack in thin aluminium sheets, polymer composite patching is one of the better repair techniques. During service, when the load acts, the patch separates from the substrate due to the stresses developed at the interface. This separation of the patch from the substrate largely depends on the geometrical factors of the patch, i.e. length, width and thickness. The optimum geometrical factors need to be incorporated for the effective and economical repair of the cracks. In this work, the optimum combination of the geometrical factors, i.e. length, width and thickness of the polymer composite patch, is obtained using the Taguchi technique with the help of the results generated in the numerical analyses.
Effect of Turning Parameter and Fiber Pullout on Machinability of Unidirectional EGFRP under Cryogenic Condition
Authors: NARESH HAZARI , Padhy Dr Chinmaya
Published: July 2023

The non-homogeneous and anisotropic nature of composites poses challenges during machining, requiring the use of specialized cutting tools. GFRP materials were selected for their excellent elasticity, corrosion resistance, and high strength, making them ideal for applications in the aerospace and automotive industries. In this work, the surface quality of UD-GFRP composite bars during CNC machining in diverse machining conditions (dry, wet, and cryogenic) was investigated while considering the fiber-pullout issue. The UD-EGFRP composite materials have been machined with a polycrystalline diamond tool. The Taguchi-L9 orthogonal-array technique is used to investigate and further analysis. Three independent-variables feed rate, rotational speed or cutting speed, and depth of cut have been taken into account for their optimal design to get better machinability of EGFRP. This study also investigates the delamination criterion in composites and establishes the correlation between its input parameters and output responses. The findings revealed that cryogenic machining led to a notable improvement of 25.21% in surface roughness compared to the other lubrication methods. Also, the reduction from 84 µm to 34 µm in fiber-pullout signifies that cryogenic cooling effectively mitigated the occurrence of fiber-pullout.
Cucumbers and Creeps: Errors in Translation Studies and in the Polish Translation
of Robert Macfarlane’s The Old Ways
Authors:   University of Białystok,
            Poland, Moroz Grzegorz
Published: July 2023

Forty years ago, André Lefevere wrote a paper in which he exposed some of the
ʻhowlingʼ errors made by American translators of Berthold Brecht and declared the theme
of errors to be unconstructive in the field of contemporary translation studies.
Krzysztof Hejwowski, a Polish translation studies scholar, believed that the notion of
errors should not be forgotten, no matter which way translation studies are heading.
This paper is both a homage to Hejwowski and his ʻconservativeʼ agenda and an attempt to
map the errors in the Polish translation of The Old Ways by Robert Macfarlane.

Purpose – The aim of the article is to diagnose the export and import activity of Polish voivodships through the prism of spatial concentration, and to investigate whether the import diversification index is the same as the export diversification index, and whether the diversification index loses its methodological value in determining both export and import activity of Polish voivodships due to the difficulties in assigning trade flows to a specific voivodeship. Reseach method – The article contains an analysis based on a review of the literature and calculations regarding the spatial concentration of exports and imports of Polish voivodships using the diversification index. The article uses the method of descriptive and explanatory research. Results – Presentation of the share of voivodeships in Poland’s export and import and the scope of spatial concentration measured by the diversification index in 1994–2019. Originality / value / implications / recommendations – The scope of spatial concentration of exports and imports expressed by the diversification index, in the analyzed period 1994–2019, did not change significantly, and the number of voivodships responsible for at least 75% of Polish exports was slightly higher than in the case of imports. At the same time, the importance of the ‘non‑classified voivodship’ category increasing each year – almost 1/4 of Polish exports and almost 1/5 of imports are not assigned to any voivodship, which implies a decrease in the significance of the methodological value of the diversification index.

Purpose – The purpose of this article is to present factors affecting the quality of human–robot collaboration (HRI) in the workplace. The impact of trust is described in detail. According to the Polish Economic Institute, between 1993 and 2018, the number of industrial robots in the world increased from 557,000 to 2.4 million. Implemented robots, cease to be just tools in human hands. Thanks to their autonomy, they are becoming known as teammates. Research method – The article is based on a literature review conducted to identify factors, particularly trust, that affect human–robot collaboration. Results – It has been revealed that research conducted in the HRI area proves that human trust in robots, is one of the most important determinants of proper cooperation. Above that, the relevance of areas such as reliability, predictability of robots, the personality of people, or appearance of robots was pointed out. The mentioned areas have a direct impact on the formation and level of trust in human–robot teams. Originality / value / implications / recommendations – The publication highlights the relevance of the area of human–robot collaboration (HRC), as part of the implementation of robots in modern enterprises. The article details which elements in the formation of HRC play the most important role. The topic of HRC is vaguely known in Poland, and as the referenced literature indicates, the correct cooperation of humans and robots is an important element affecting the success of robotization. Learning how HRC works is one of the challenges facing today’s organizations.
