The multilingual workplace realities of Polish truckers: A case study in the Netherlands
Authors: Dijkstra Bianca E. , Coler Matt , Redeker Gisela 
Published: November 2020

AbstractAlthough international truckers are essential to the European supply chain, we know little about how they deal with their frequent multilingual workplace interactions. This paper examines the effects of participants’ Individual Multilingual Repertoires (Pitzl, Marie-Luise. 2016. World Englishes and creative idioms in English as a lingua franca.World Englishes35(2). 293–309.https://doi.org/10.1111/weng.12196) on their behavior and attitude toward multilingual interactions. Five Polish truckers and six Dutch logistics professionals were observed and interviewed. An ethnographic case study approach allowed us to consider interactions from multiple perspectives. Findings from the study reveal that some, but not all, Polish truckers struggle to interact in the most common lingua francas in the Netherlands: English and German. We show that some of the Dutch logistics professionals have a low opinion of foreign drivers’ linguistic abilities, which impairs the potential to find shared multilingual resources, and ultimately to improve communication skills. Results of the study contribute to an understanding of the dynamics of multilingual interactions in the workplace. Practical suggestions for logistics professionals and future research are identified.

Abstract
Active metasurfaces, in which the optical property of a metasurface device can be controlled by external stimuli, have attracted great research interest recently. For optical switching and modulation applications, high-performance active metasurfaces need to show high transparency, high power efficiency, as well as ultrafast switching and large-scale fabrication capability. This paper reports Au/VO2-based active metasurfaces meeting the requirements above. Centimeter-scale Au/VO2 metasurfaces are fabricated by polystyrene sphere colloidal crystal self-assembly. The devices show optical modulation on-off ratio up to 12.7 dB and insertion loss down to 3.3 dB at 2200 nm wavelength in the static heating experiment, and ΔT/T of 10% in ultrafast pump-probe experiments. In particular, by judiciously aligning the surface plasmon resonance wavelength to the pump wavelength of the femtosecond laser, the enhanced electric field at 800 nm is capable to switch off the extraordinary optical transmission effect at 2200 nm in 100 fs time scale. Compared to VO2 thin-film samples, the devices also show 50% power reduction for all-optical modulation. Our work provides a practical way to fabricate large-scale and power-efficient active metasurfaces for ultrafast optical modulation.

AbstractAluminum has attracted a great deal of attention as an alternative plasmonic material to silver and gold because of its natural abundance on Earth, material stability, unique spectral capability in the ultraviolet spectral region, and complementary metal-oxide-semiconductor compatibility. Surprisingly, in some recent studies, aluminum has been reported to outperform silver in the visible range due to its superior surface and interface properties. Here, we demonstrate excellent structural and optical properties measured for aluminum epitaxial films grown on sapphire substrates by molecular-beam epitaxy under ultrahigh vacuum growth conditions. Using the epitaxial growth technique, distinct advantages can be achieved for plasmonic applications, including high-fidelity nanofabrication and wafer-scale system integration. Moreover, the aluminum film thickness is controllable down to a few atomic monolayers, allowing for plasmonic ultrathin layer devices. Two kinds of aluminum plasmonic applications are reported here, including precisely engineered plasmonic substrates for surface-enhanced Raman spectroscopy and high-quality-factor plasmonic surface lattices based on standing localized surface plasmons and propagating surface plasmon polaritons, respectively, in the entire visible spectrum (400–700 nm).

Abstract
Structural coloration using metasurfaces has been steadily researched to overcome the limitations of conventional color printing using pigments by improving the resolution, lowering the toxicity, and increasing the durability. Many metasurfaces have been demonstrated for dynamic structural coloration to convert images at the visible spectrum. However, the previous works cannot reach near-zero scattering when colors are turned-off, preventing it from being cryptographic applications. Herein, we propose a completely on/off switchable structural coloration with polarization-sensitive metasurfaces, enabling full-colored images to be displayed and hidden through the control of the polarization of incident light. It is confirmed that the nanostructure exhibits the polarization-dependent magnetic field distributions, and near-zero scattering is realized when the polarization of incident light is perpendicular to the long axis of the nanofins. Also, the metasurfaces are made up of triple-nanofin structures whose lengths affect locations of resonance peaks, resulting in full-color spectrum coverages. With such advantages, a QR code image, a two-color object image, and an overlapped dual-portrait image are obtained with the metasurfaces. Such demonstrations will provide potential applications in the fields of high-security information encryption, security tag, multichannel imaging, and dynamic displays.

Framing the Material Global: The Grounded Politics of HIV Testing Scale-Up
Authors: Tseng Po-Chia 
Published: November 2020

Abstract
Drawing on the framework of transnational materiality (Gille 2014), a conceptual contribution from the Framing the Global project, this article examines how HIV testing and counselling services became a site of political contestation in Taiwan since expanding service delivery was proposed as a response to the HIV epidemic by global health institutions in the 2000s. This global scheme, the study argues, not only reshaped the organization and practices of HIV service delivery, but also generated vulnerability as these practices connected to HIV-positive people’s lives were largely governed by global models and national programs that may not fully reflect local concerns. In response, local NGO workers politicize service delivery in part by transnationally adopting and promoting practices that attend more carefully to localized forms of vulnerability. Using qualitative data collected in Taiwan, the analysis reveals a grounded politics of HIV service delivery that highlights the materialization of vulnerability and its management.
A solid-phase extraction method that eliminates matrix effects of complex pulp mill effluents for the analysis of lipophilic wood extractives

Published: November 2020

Abstract
The extraction of lipophilic wood extractives from pulp and paper process waters proves to be a challenging task, due to harsh and alternating process and sample conditions. This study has determined the potential use of polymeric sorbents for solid-phase extraction (SPE) and compared to classical silica-based reversed-phase packed columns, with polymeric hydrophilic-lipophilic balanced (HLB) cartridges being the sorbent with the most potential. Recovery functions were obtained with an internal standard mixture representative for the main lipophilic wood extractive groups, which are fatty acids and alcohols, sterols, sterol esters and triglycerides. The impact of pH, sample volume and sample matrix, expressed as TOC and cations, on the retention behavior of lipophilic extractives during SPE of industrial samples were determined with polymeric HLB sorbent. High variations in the composition of pulp mill matrices led to different optimal extraction conditions. Thus, a new SPE protocol was developed, which bypasses matrix interferences and omits the loss of analytes due to sample preparation. The method is applicable to different pulp mill effluents with large discrepancies in pH and sample matrices, resulting in recoveries >90 % with RSD <5 % for all lipophilic wood extractives.

Published: November 2020

AbstractThe present study analyzes the composition of pine wood cultivated on artificial plantations in the Leningrad Oblast (Region). Comparing to pine wood from natural stands, a smaller heartwood zone along the height of the pine trunk and a lower content of resinous substances are noted. The content of cellulose and lignin in the heartwood and sapwood of pine is distributed differently along the trunk. The distribution of pentosans and water-soluble substances in the heartwood and sapwood along the trunk is associated with the lignin complex. The component composition of the studied pine wood from planted stands is quite uniform in its indicators if compared to the wood of older natural stands. Sulphate pulping of planted pine wood showed a higher yield of technical cellulose than the average yield from wood obtained at natural stands of the studied region.
Two-photon polymerization nanolithography technology for fabrication of stimulus-responsive micro/nano-structures for biomedical applications
Authors: Huang Zhenjia , Chi-Pong Tsui Gary , Deng Yu , Tang Chak-Yin 
Published: November 2020

AbstractMicro/nano-fabrication technology via two-photon polymerization (TPP) nanolithography is a powerful and useful manufacturing tool that is capable of generating two dimensional (2D) to three dimensional (3D) arbitrary micro/nano-structures of various materials with a high spatial resolution. This technology has received tremendous interest in cell and tissue engineering and medical microdevices because of its remarkable fabrication capability for sophisticated structures from macro- to nano-scale, which are difficult to be achieved by traditional methods with limited microarchitecture controllability. To fabricate precisely designed 3D micro/nano-structures for biomedical applications via TPP nanolithography, the use of photoinitiators (PIs) and photoresists needs to be considered comprehensively and systematically. In this review, widely used commercially available PIs are first discussed, followed by elucidating synthesis strategies of water-soluble initiators for biomedical applications. In addition to the conventional photoresists, the distinctive properties of customized stimulus-responsive photoresists are discussed. Finally, current limitations and challenges in the material and fabrication aspects and an outlook for future prospects of TPP for biomedical applications based on different biocompatible photosensitive composites are discussed comprehensively. In all, this review provides a basic understanding of TPP technology and important roles of PIs and photoresists for fabricating high-precision stimulus-responsive micro/nano-structures for a wide range of biomedical applications.

Published: November 2020

Abstract
Hardened layers are commonly required for automotive components after their production using a machining process in order to enhance the service life of these components. This study investigates the possibility of producing a nanostructured machined surface which can increase the hardness of the machined surface by varying the machining parameters under cryogenic conditions in end milling of AISI 4340. The end milling experiments were performed using multi-layered TiAlN- and AlCrN-coated carbide. Prior to the experiment, a finite element method (FEM) was used to simulate the cutting temperature generated and it had been found that at cutting speed of 200–300 m/min, feed rate of 0.15–0.3 mm/tooth, axial depth of cut of 0.3–0.5 mm, and radial depth of cut of 0.2–0.35 mm, the temperature generated can be sufficiently high to cause austenitic transformation. A field emission scanning electron microscope (FESEM) equipped with angle selective backscattered (AsB) detection analysis was used to investigate the microstructure and machined-affected layers of the machined surfaces. The crystallographic orientation/phase change and nano-hardness were analysed through X-ray diffraction (XRD) and a nano-hardness testing machine. The results showed that the cryogenic machining had significantly affected the surface integrity characteristics of the AISI 4340 alloy due to refined microstructure, favourable phase structure, and higher hardness near the surface layer. The results of this study may be useful in providing an insight into a potential technological shift from conventional surface case hardening processes to the present technique.

Published: November 2020

Abstract
Green fabrication of metal nanoparticles (NPs), using natural reducing and stabilizing agents existed in plants and their derivatives, due to their unique properties, has gained more attention. The present study focuses on the synthesis of gold (Au), silver (Ag) and selenium (Se) NPs using coffee bean extract under hydrothermal conditions (1.5 atm and 121°C, for 15 min). Coffee bean extract obtained in 2 h processing using Clevenger apparatus and Fourier transform-infrared (FT-IR) spectroscopy indicated five highlighted peaks, namely, hydroxyl, amide, aromatic, alkane and ring groups. Dynamic light scattering analysis revealed that among three different NPs formed, fabricated Ag NPs had small particle size (153 nm) and high zeta potential value (16.8 mV). However, synthesized Au NPs had minimum polydispersity index (0.312). Results also indicated that fabricated Au, Se and Ag NPs had low antioxidant activity with values of 9.1, 8.9 and 8.7%, respectively. Morphological and antibacterial activity assessments, demonstrated that synthesized Ag, Au and Se NPs had spherical shape and high bactericidal activity against E. coli and S. aurous. Obtained results indicated that the synthesized NPs, can be utilized in various areas.

Published: November 2020

Abstract
Pressurised IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a novel surgical technique to administer aerosolized chemotherapy into the abdominal cavity as treatment for peritoneal metastasis from various cancers. As the surgery is unique and there are concerns about occupational hazards, specific anaesthetic setup and techniques are required. Notably, our institution’s experience with PIPAC has enlightened us that anaesthesia requirements during PIPAC are generally uncomplicated and that the majority of the patients undergoing PIPAC do not require invasive monitoring, advanced intra or postoperative analgesia like epidurals or PCA. The need for postoperative intensive unit care is also not required in routine PIPAC cases. We describe the anaesthetic considerations involved and the detailed preparation of staff, space, anaesthetic equipment and drugs to facilitate the appropriate modifications for anaesthesia monitoring and maintenance for an elective set up as well as our standard operating procedure for an emergency situation should it arise.
Adsorption from liquid metals: an approach for recovery of radionuclides from irradiated targets
Authors: Zhuikov Boris , Ermolaev Stanislav 
Published: November 2020

Abstract
Adsorption of radionuclides in no-carrier-added (NCA) amounts from liquid metals оf Rb, Pb, and Ag was investigated. 82Sr may be recovered from metallic irradiated Rb-target via adsorption onto various surfaces. A high chemical yield is achieved at Sr-sorption from molten Rb of big mass directly onto the inner surface of the target shell at about 300 °C. The investigation showed that the formation and dissolution of oxide sol particles of rubidium oxide, where 82Sr is initially adsorbed in SrO form, play an important role in the mechanism of adsorption. The approach is prospective for different modes in “off-line” and “on-line” 82Sr production. Direct sorption of different NCA radionuclides from molten Pb and Ag was also investigated. Chemical nature of the surface (Ta, Ni, Ti, Mo, Al, or quartz) is very critical for sorption of 188,189Ir, 188Pt,198Au,97Ru,185Os,182mRe,99Mo and 99mTc from molten Pb, and for sorption of 100Pd,101mRh,97Ru, 96Tc from molten Ag.
The subiculum and its role in focal epileptic disorders
Authors: Lévesque Maxime , Avoli Massimo 
Published: November 2020

Abstract
The subicular complex (hereafter referred as subiculum), which is reciprocally connected with the hippocampus and rhinal cortices, exerts a major control on hippocampal outputs. Over the last three decades, several studies have revealed that the subiculum plays a pivotal role in learning and memory but also in pathological conditions such as mesial temporal lobe epilepsy (MTLE). Indeed, subicular networks actively contribute to seizure generation and this structure is relatively spared from the cell loss encountered in this focal epileptic disorder. In this review, we will address: (i) the functional properties of subicular principal cells under normal and pathological conditions; (ii) the subiculum role in sustaining seizures in in vivo models of MTLE and in in vitro models of epileptiform synchronization; (iii) its presumptive role in human MTLE; and (iv) evidence underscoring the relationship between subiculum and antiepileptic drug effects. The studies reviewed here reinforce the view that the subiculum represents a limbic area with relevant, as yet unexplored, roles in focal epilepsy.
Economic Analysis of Accident Law: A New Liability Rule that Induces Socially Optimal Behaviour in Case of Limited Information
Authors: Srivastava Astha , Srivastava Ankur 
Published: November 2020

Abstract
In accident law, we seek a liability rule that will induce both the parties to adopt socially optimal levels of precaution. Economic analysis, however, shows that none of the commonly used liability rules induce both parties to adopt optimal levels, if courts have access only to ‘Limited Information’ on. In such a case, it has also been established (K. (2006). Efficiency of liability rules: a reconsideration. J. Int. Trade Econ. Dev. 15: 359–373) that no liability rule based on cost justified untaken precaution as a standard of care can be efficient. In this paper, we describe a two-step liability rule: the rule of negligence with the defence of relative negligence. We prove that this rule has a unique Nash equilibrium at socially optimal levels of care for the non-cooperative game, and therefore induces both parties to adopt socially optimal behaviour even in case of limited information.
Contextual Ethics: Taking the Lead from Wittgenstein and Løgstrup on Ethical Meaning and Normativity
Authors: Eriksen Cecilie 
Published: November 2020

AbstractA prominent trend in moral philosophy today is the interest in the rich textures of actual human practices and lives. This has prompted engagements with other disciplines, such as anthropology, history, literature, law and empirical science, which have produced various forms ofcontextual ethics. These engagements motivate reflections on why and how context is important ethically, and such metaethical reflection is what this article undertakes. Inspired by the work of the later Wittgenstein and the Danish theologian K.E. Løgstrup, I first describe one of the ways in which context plays a central role with regard to ethical meaning and normativity. I then examine how ‘context’ is to be defined, and finally I discuss some of the questions which arise when giving context prominence in ethics – namely, how to delimit the scope of relevant context, the relevant traits of a particular context and what ‘the ethical’ is.
