Antioxidative Stress and Hepatoprotective Activities of Leaf Extract and Fractions of Setaria megaphylla in Plasmodium berghei Infected Mice
Authors: William Ndanti Bartholomew , Bassey Augustine Lawrence , Udobang John Akpan , Okokon Jude Efiom 
Published: June 2023

Setaria megaphylla (Steud) Dur & Schinz (Poaceae), a perennial grass used traditionally in the treatment of various diseases such as malaria was, investigated for antioxidative stress activity in Plasmodium berghei-infected mice. The leaf extract (200-600 mg/kg) and fractions (hexane, dichloromethane, ethyl acetate and methanol; 400 mg/kg) of S. megaphylla were investigated for antioxidative stress and hepatoprotective activities in Plasmodium berghei-infected mice using a modified suppressive test model. Antioxidative stress and hepatoprotective potentials were assessed by determining oxidative stress markers levels, liver function indices and histopathology of liver. The extract/fractions progressively reduced parasitaemia induced by chloroquine-sensitive P. berghei infection with the methanol fraction exerting the highest activity. The leaf extract and fractions caused significant (p<0.05 – 0.001) increases in the levels of oxidative stress markers enzymes and molecules (SOD, CAT, GPx, GSH) and also reduced MDA level significantly (p<0.05) in the livers of the treated-infected mice. The extract/fractions treatment caused reduction in liver enzymes (ALT, AST and ALP), total and conjugated bilirubin. Histology of livers revealed absence or significant reductions in pathological features in the treated infected mice compared to untreated infected mice. The leaf of S. megaphylla may possess antioxidative stress and hepatoprotective effects which may in part be mediated through the chemical constituents of the plant.

Published: June 2023

The leaf of Solanum anomalum used in ethnomedicine for the treatment of various ailments such as diabetes was evaluated for antioxidative stress and hepatoprotective potentials against hepatic injuries in alloxan-induced diabetic rats. Antioxidative stress and hepatoprotective activities of leaf extract and fractions (70-210 mg/kg) were assessed by determining oxidative stress markers levels, liver function indices and histopathological study of livers of treated rats. The leaf extract and fractions caused significant (p<0.05 – 0.001) increases in the levels of oxidative stress markers (SOD, CAT, GPx, GSH) in the livers of the treated diabetic rats. The extract/fractions treatment caused reduction in liver enzymes (ALT, AST and ALP), total and direct bilirubin. Histology of the livers revealed absence or significant reductions in pathological features in the treated diabetic rats compared to untreated diabetic rats. The results show that the leaf extract and fractions of S. anomalum has antioxidative stress and hepatoprotective potentials which may be due to the antioxidant activities of their phytochemical constituents.
Higher order Ambrosio–Tortorelli scheme with non-negative spatially dependent parameters
Authors: Fonseca Irene , Liu Pan , Lu Xin Yang 
Published: June 2023

AbstractThe Ambrosio–Tortorelli approximation scheme with weighted underlying metric is investigated. It is shown that it Γ-converges to a Mumford–Shah image segmentation functional depending on the weightω⁢d⁢x{\omega\,dx}, where ω is a special function of bounded variation, and on its values at the jumps.
Minimizers of nonlocal polyconvex energies in nonlocal hyperelasticity
Authors: Bellido José C. , Cueto Javier , Mora-Corral Carlos 
Published: June 2023

Abstract
We develop a theory of existence of minimizers of energy functionals in vectorial problems based on a nonlocal gradient under Dirichlet boundary conditions.
The model shares many features with the peridynamics model and is also applicable to nonlocal solid mechanics, especially nonlinear elasticity.
This nonlocal gradient was introduced in an earlier work, inspired by Riesz’ fractional gradient, but suitable for bounded domains.
The main assumption on the integrand of the energy is polyconvexity.
Thus, we adapt the corresponding results of the classical case to this nonlocal context, notably, Piola’s identity, the integration by parts of the determinant and the weak continuity of the determinant.
The proof exploits the fact that every nonlocal gradient is a classical gradient.

‘Just kidding?’ – an exploratory audience study into the ways Flemish youth with a minoritized ethnic identity make sense of ethnic humor and the politics of offense
Authors: Lion Anke , Dhaenens Frederik 
Published: June 2023

Abstract
Recently, ethnic humor (targeting ethnoreligious identities) is increasingly questioned in European and Western countries, sparking controversy on online and traditional media platforms. Absent from the mediated and academic debate are the opinions from targeted subjects of the joke. This qualitative audience study aims to add to critical humor scholarship by providing insight into how targeted groups make sense of disputes of offense. We interviewed 35 participants (ages 15–24) with a minoritized ethnic identity (mostly a Moroccan or Turkish diasporic background) and religious identity (all identified as Muslim) on how they negotiate offensive (ethnic) humor. Moreover, we asked participants to reflect on the politics of offense (i.e. the power relations underlying the process of publicly claiming offense) and the role media play in the discussion of offended feelings in relation to (ethnic) humor. A thematic analysis of three focus groups indicates how participants’ negotiations were always influenced by contextual factors and tied to their identities, both on a sociopolitical and personal level. Further, participants were highly conscious about their minoritized position in debates on offensive ethnic humor and how this relates to societal power inequalities. As such, they recognized how the politics of offense regarding ethnic humor highlight boundaries between social groups.
Dissimilar joining of titanium to aluminum using friction stir welding process and weld joint characterization
Authors: Basude Ambadas , Kumar Adepu , Rajasingh George , Kishore Mugada Krishna 
Published: June 2023

Abstract
The present investigation studies the solid-state joining of difficult-to-weld aerospace materials such as titanium alloy (Ti6Al4V, ELI) and pure aluminum. Due to the wide difference in thermo-mechanical properties, it was a challenging task to establish a dissimilar metal joint. The friction stir welding process with a conically shaped tungsten carbide tool was used in the present investigation to join the dissimilar titanium alloy and aluminum in the lap joint configuration. After a series of pilot experiments, the optimum test conditions to produce the defect-free joint are spindle speed of 1200 rpm, feed rate of 40 mm min−1, tool tilt angle of 1°, and 1 mm tool offset towards the aluminum side. The results show that a good joint was achieved with a maximum joint strength of 89 MPa. The dissimilar joints are characterized by macrostructure, microstructure, microhardness, and scanning electron microscopic analysis.
Exploring the learning benefits of collaborative writing in L2 Chinese: a product-oriented perspective
Authors: Yang Li , Polin Lini Ge 
Published: June 2023

Abstract
This study explored the benefits of collaborative writing in L2 Chinese by (a) comparing the texts written collaboratively versus individually and (b) investigating the effects of collaborative writing on subsequent individual writing. Forty-four English-speaking students enrolled in an intermediate Chinese course were assigned to a collaborative writing group and an individual writing group. All participants completed a timed in-class writing task at the beginning and end of the semester, working as pre-and post-tests. The participants in the collaborative writing group completed two out-of-class writing assignments in pairs through online written chats, while those in the individual writing group completed the same tasks individually. The texts were analyzed for content, organization, character and lexical accuracy, and non-parametric tests (Mann-Whitney U tests and Wilcoxon signed ranks tests) were performed on the data for statistical analyses. The online chats were segmented into different episodes (e.g., language- and content-related episodes) to provide in-depth explanation for the findings. The effect of collaboration was examined from two aspects. The comparison between the texts written collaboratively versus individually showed that the collaborative texts were significantly better than those composed individually in organization and lexical accuracy. The pre-post comparison between collaborative and individual writing groups observed that collaboration contributed positively to subsequent individual writing quality by significantly impacting its content and lexical accuracy.
Design of an IoPT approach to create a cocktail robot station with robotic arm: components, interfaces and control
Authors: Klievtsova Nataliia , Fuschlberger Marcel 
Published: June 2023

AbstractSuccessful and profitable companies in the 21st century have to integrate and adapt modern technologies to reach productivity and sustainability goals. While large enterprises have the resources (human, knowledge, and technology) to incorporate automation hardware and the required computational means to support automation, for small and medium enterprises (SMEs) finding the necessary resources is much more difficult. Even though benefits from such modifications are obvious (i.e., gain new clients, improve current process performance or break into new market), SMEs often lack the human resources and knowledge to implement automation. With the development of the Internet of Things (IoT), devices, sensors and platforms are becoming more affordable and available for companies and businesses, that are not connected with IT technologies, industrial sector, etc. In order to simplify automation for SMEs, simple and standardized integration procedures and best practice examples are important. In this paper we propose the concept and design of a smart bar system that is based on the Internet of Processes and Things (IoPT) concept which is able to prepare and serve drinks to clients based on smart features.
Convergence analysis of Inexact Newton–Landweber iteration with frozen derivative in Banach spaces
Authors: Mittal Gaurav , Giri Ankik Kumar 
Published: June 2023

Abstract
In this paper, we study the convergence analysis of the inexact Newton–Landweber iteration method (INLIM) with frozen derivative in Hilbert as well as Banach spaces. To study the convergence analysis, we incorporate the Hölder stability of the inverse mapping and Lipschitz continuity of the Fréchet derivative of the forward mapping. Moreover, we derive the convergence rates of INLIM in Hilbert as well as Banach spaces without using any extra smoothness condition. Finally, we compare our convergence rates results with that of several other frozen methods proposed in the literature to solve inverse problems.
The year’s work in ecolinguistics 2022
Authors: Ha Changchen 
Published: June 2023

AbstractMany important results were achieved in ecolinguistic studies in 2022. This article reviews ecolinguistic studies in 2022, which aims to shed light on the future research directions. It consists of two main themes. First, studies are reviewed in terms of research areas, conferences, monographs, and journals. Then, based on the above results, issues are summarized and trends are predicted for the next phase of ecolinguistic studies. The review shows that the research scope of ecolinguistics has gradually developed from micro to macro. In addition, many academic conferences on ecological issues were held worldwide, and several publishing houses and journals published dedicated volumes and issues on ecolinguistics. It is suggested that ecolinguistic studies in the future should pay attention to the following points: continuing to emphasize the significance of ecolinguistics in the framework of linguistics, clarifying the interdisciplinary and transdisciplinary attributes of ecolinguistics, and strengthening inquiries into issues such as ecological literacy, ecological awareness, and ecosophy.
Indonesian Job Creation Law: Neoliberal Legality, Authoritarianism and Executive Aggrandizement Under Joko Widodo
Authors: Setia Negara Tunggul Anshari , Anggoro Syahriza Alkohir , Koeswahyono Imam 
Published: June 2023

Abstract
On October 5, 2020, President Joko Widodo (Jokowi) passed Law no. 11/2020 on Job Creation (Job Creation Law/JCL) designed to improve Indonesia’s private investment climate. The law changed various legal landscapes that were identified as obstacles to accelerated development and economic growth. However, the Law has sparked widespread protests because it can potentially encourage environmental damage, exacerbate workers’ vulnerability and increase socioeconomic inequality. Describing JCL as a neoliberal legality project, this paper explores the elected executive’s role in mobilizing authoritarian state practices through disciplinary measures that undermine democratic accountabilities. It is argued that the configuration between the pre-existing illiberal democracy and Jokowi’s autocratic tendencies offers predatory business alliances an adequate legal and institutional platform to formulate a neoliberal legal breakthrough while eliminating resistance to them. Through a socio-legal analysis of the three areas targeted by the JCL amendments, we further argue that Jokowi’s success in advocating for his preferred neoliberal agenda hinges on what is called an executive aggrandizement strategy. This is characterized by interventions designed to safeguard the neoliberal legality preferences promoted by the elected executive from the disruption of meaningful checks and balances in the future, thereby deepening the features of authoritarian statecraft. This paper contributes to an advanced understanding of the bleak picture of Indonesian democracy over the past few years by proposing neoliberal legality as one of the ingrained legal characteristics of Jokowi’s authoritarian regime.
Citizen science reveals the first occurrence of the greater white-toothed shrew Crocidura russula in Fennoscandia
Authors: van der Kooij Jeroen , Nyfors Ebbe 
Published: June 2023

Abstract
The occurrence of the non-native, greater white-toothed shrew Crocidura russula in the Stavanger area in Southwestern Norway was brought to our attention by two records from the public (from 2012 and 2017). A citizen-science project, based on targeted media-calls between 2017 and 2019, resulted in 78 reported observations. A correct species identity, using photographs and collected specimen, was confirmed for 103 observations from 68 unique localities. Many of the sightings resulted directly from the media calls, but several were made both years before and after (ranging from 2012 to 2021). The minimum area of occurrence was 60 km long and 20 km wide and is characterised by one of the mildest climates in Norway. No clear expansion pattern was evident from the data, though an introduction between 2000 and 2010 seems likely. As only a few other shrew species were reported by the public, it is possible that the white-toothed shrew has outcompeted native shrews in the area. However, this could be biased by the nature of the media call or the commensal lifestyle of the shrew. Media calls beyond the area of occurrence did not result in any reports of the species. The introduction route and origin of the present population remain unclear.
pH dependence of glyphosate adsorption from aqueous solution using a cationic cellulose microfibers (cCMF) biosorbent

Published: June 2023

Abstract
Currently, the agricultural sector is responsible for the contamination of groundwater and springs due to the excessive use of pesticides, which represents a risk to human and environmental health. Among pesticides, glyphosate is the most used herbicide to increase agricultural production, however, it can cause intoxication in humans and has been classified as a potentially carcinogenic agent. Alternatives for removing these contaminants from water have been studied and discussed, including biosorption, a physical-chemical process that removes substances from solutions using a natural and renewable material. In this sense, this work studied the process to obtain cationic cellulose microfibers (cCMF) from sugarcane bagasse residue, by cellulose isolation followed by cationization reaction with Girard T reagent to promote a new adsorbent for glyphosate removal from water. It was observed that cCMF structure maintains the fibrillar morphology after the microfiber production (1.375 mmol g−1 oxidation degree). Results of zero charge of cCMF microfibers showed an isoelectric point pH = 5.4 ± 0.016 and the highest adsorption capacity was reached at pH 14 (59.21 %), showing a clear pH dependence on the adsorption process. Thereby, the cCMF can be produced from sugarcane bagasse residue being applied as a potential biomaterial for removing organic compounds from water.

Investigating the Economic Consequence of Terrorism in Sub-Saharan Africa: Evidence from a Dynamic Panel Model
Authors: Agu Christian , Mbah Augustine Jideofor , Agu Chukwuagoziem Samuel 
Published: June 2023

Abstract
This study examines the economic consequence of terrorism in Sub-Saharan Africa (SSA) with a panel of 38 countries between 2010 and 2020. Specifically, the study examined the impact of terrorism on economic growth, international tourism demand, income inequality, unemployment rate, and inflation rate. The study employed the two-step system GMM and quantile regression for the estimation. The results show that terrorism has had a significant negative impact on economic growth in SSA. Similarly, the study results indicate that terrorism impacts negatively on international tourism demand, widens the income gap, and increases the rate of unemployment and inflation in SSA. Furthermore, the two governance institution indicators employed in the study (government effectiveness and control of corruption) shows a significant negative impact on economic growth in the zone, while credit to the private sector and human capital had performed abysmally in the zones’ growth trajectory. These findings were further supported by the quantile regression results. The study employed both system GMM model and quantile regression in the analysis. The use of these two different methods makes the results obtained to be robust and efficient for policy purpose, which no other author has done before now.
