Just call me Dave

Abstract
This paper seeks to show how male politicians can draw on performances of masculinity to appeal to voters. The
paper uses former UK Prime Minister David Cameron as an example of how performances of masculinity interact with the opportunistic
use of populist forms of political engagement. It argues that while Cameron’s performances of populism are often situated in
compatible policy initiatives such as the “big society”, we can also identify a more sustained deployment of masculine discourse
in “performances” of alignment with the people. This paper shows how these gendered performances of political leaders mirror
changes in society, while exploring how they can also be politically hazardous. Whilst the “new man” might appeal to Western
voters, this paper shows how Cameron draws on this performance of masculinity in his first term as UK prime minister; at the same
time, showing the limits to such appeal in an age of austerity.
What does a verb? Indicate sentence type
Authors: Speyer Augustin 
Published: January 2020

AbstractAn important task of the verb in German is to indicate sentence type. Depending on where the verb is positioned, the clause is a declarative (verb after the first constituent, which can be any constituent), wh-interrogative (verb after the first constituent, being the wh-phrase), yes/no-interrogative (verb in first position, bearing indicative or subjunctive mood) or imperative clause (verb in first position, bearing imperative mood). This system developed out of a system in which sentence type was indicated by clause-final sentence mood particles, as is usual in older Indo-European (and Semitic) languages. In declarative sentences, the verb-second syntax only came about shortly before the Old High German attestation sets in. We can trace the gradual development of the modern German verb-second syntax with variable prefield from a clear topic-comment structure to a more flexible structure.
Between life and death: strategies to reduce phototoxicity in super-resolution microscopy
Authors: Tosheva Kalina L , Yuan Yue , Matos Pereira Pedro , Culley Siân , Henriques Ricardo 
Published: January 2020

Abstract
Super-resolution microscopy (SRM) enables non-invasive, molecule-specific imaging of the internal structure and dynamics of cells with sub-diffraction limit spatial resolution. One of its major limitations is the requirement for high-intensity illumination, generating considerable cellular phototoxicity. This factor considerably limits the capacity for live-cell observations, particularly for extended periods of time. Here, we give an overview of new developments in hardware, software and probe chemistry aiming to reduce phototoxicity. Additionally, we discuss how the choice of biological model and sample environment impacts the capacity for live-cell observations.

Abstract
A multiscale modelling framework, especially for corrosion modelling, requires not only robust computational tools but also an efficient datacentric architecture for handling information exchange at different modelling scales. Different computational solvers require and produce data in different programming languages and specific formats signifying a strong non-uniformity for an easy nexus with other solvers. This non-uniformity has created a need to focus on intermittent state-of-the-art datacentric software tools which aim to bridge data exchange heterogeneity across diverse set of solvers. Data organization in the form of metadata structures are presented as a standard for a coherent information representation regardless of the diverse nature of data formats specific to a scientific discipline. This fundamental work presents the concept, underlying terminology and working mechanism of a datacentric architecture tool SOFT5 for exchanging and interfacing data-flow between solvers and its present application to a concrete technology multiscale simulation network as a potential application.

stripes induce formation of GaN nanowires while a compact GaN layer is formed outside the stripes. We show that the ratio of nanowire length h to the thickness of the compact layer d can be tailored by adjusting impinging gallium and nitrogen fluxes. Calculations of the h/d aspect ratio were performed taking into account dependence of nanowire incubation time on the growth parameters. In agreement with calculations we found that the value of h/d ratio can be increased by increasing the N/Ga flux ratio in the way that the N-limited growth regime determines nanowire axial growth rate while growth of compact layer remains Ga-limited. This ensures the highest value of the h/d aspect ratio. Local modification of GaN growth kinetics caused by surface diffusion of Ga adatoms through the boundary separating the Al

stripe, which delays nanowire nucleation onset and leads to reduced length of GaN nanowires in the vicinity of the stripe edge. Simultaneously the growth on the GaN/sapphire substrate is locally enhanced, so the planar GaN layers adopts a typical edge shape of mesa structures grown by selective area growth.

Published: January 2020

Abstract
A new environmental transmission electron microscope has been installed in Lund in order to investigate the growth of III–V semiconductor nanowires by metal-organic chemical vapour deposition. We report here on the concepts behind the design of the facility and on details of the operation, and we refer to early results to highlight the new information that can be accessed from in situ studies. The installation includes a gas handling system that delivers the precursors to III–V semiconductor growth under controlled conditions. The core microscope is a Hitachi HF-3300S 300 kV transmission electron microscope with additional pumping that can handle up to 6 Pa of gas injected into the specimen area, or up to 400 Pa if an apertured lid is fitted to the holder. Various custom specimen holders incorporate precursor gas lines, a heating chip or a double tilt mechanism. The polepiece gap has been expanded to accommodate the holders, while the combination of an imaging aberration corrector and a cold field emission gun delivers a point resolution of 86 pm. Single images with atomic level detail are collected by one camera while another camera provides real-time video recording. A scanning unit offers high angle annular dark field and secondary electron images, and compositional microanalysis is performed with energy dispersive spectroscopy. In summary, III–V nanowires have been grown successfully in situ across a range of controlled conditions such as substrate temperature and precursor partial pressures. Atomic resolution images and movies, and spectroscopy data taken during this growth allow detailed measurements of structures, compositions and growth rates—data that are otherwise hard or impossible to obtain from ex situ studies—and further our understanding of the mechanisms of crystal growth.
The transient voltage response of ReBCO coated conductors exhibiting dynamic resistance

Published: January 2020

Abstract
Dynamic resistance can be observed in a superconducting tape carrying a DC current which is exposed to an oscillating magnetic field. This effect is attributed to the interaction between the transport current and moving fluxons, and can occur in various superconducting components including high temperature superconducting (HTS) flux pumps, fast-ramping magnets and HTS rotating machines. Although conventionally expressed in terms of a DC ‘resistance,’ the phenomenon is inherently transient in nature, and the voltage drop across the superconductor follows a time-dependent periodic waveform. Here we present experimental measurements of the dynamic resistance of different REBCO tapes carrying a DC current and exposed to an oscillating perpendicular field. Measurements of both the transient voltage waveforms and the time-averaged DC resistances are compared with numerical finite element simulations obtained using the H-formulation. We observe clear variations between the voltage response from different tapes, which can be understood in terms of their differing J
c(B, θ) dependence. In particular, a key feature of the experimentally measured waveforms is the emergence of a split ‘double peak’ at higher applied fields. Graphical visualisations of the finite element data show that this coincides with a periodic increase in J
c(B, θ) throughout the tape. This occurs during each cycle at those times when the applied field falls below the shielding threshold of the tape (as the penetrating field within the tape then approaches zero). Our findings show that models which assume a constant J
c irrespective of local field strength cannot capture the full range of behaviour observed by experiment. This emphasises the importance of employing experimentally measured J
c(B, θ) data when simulating transient effects in HTS materials.

Published: January 2020

Abstract
Guci Hot Spring is one of the tourist destinations in Central Java Province renowned for its beautiful scenery as well as its health-healing benefit. In 2016, this touristic destination attracted more than 650.000 visitors, this number is growing each year. However, this touristic spot has its hidden hazard and risk of the Slamet Volcano eruption. The historical eruptions of this volcano, recorded since the 18th century, have shown that this volcano is known for its explosive type of eruption. Despite its potential hazard and risk, this hot spring area is growing continuously as a touristic spot. Therefore, this study aims to understand tourists’ perception on volcanic hazard and risk in this area, by interviewing 31 respondents using questionnaires. The results show that 74% of respondents are aware that Slamet Volcano has different potential hazards such as volcanic ashfall, lahars, lava and pyroclastic flows. Although Guci Hot Spring is located in Slamet volcanic hazard area, only a few tourists know this information (42%). Majorities of the respondents did not have any experience on volcanic disaster (68%). Most of the respondents did not get any information on Slamet volcanic hazard (58%), while others only get information through television and/or social media. Nevertheless, almost all of the respondents claimed that they will follow any instructions given by government or related institutions if any volcanic eruption occurs (97%). Therefore, awareness program towards tourists in the volcanic touristic spot should be strengthened through different means to give information on volcanic hazard, its risk as well as mitigation and crisis management.

Published: January 2020

Abstract
Geologically, the karst area of “Bukit Bangkai” is located in the southeastern part of the Meratus Karst Mountains, South Kalimantan. The landscape of the “Bukit Bangkai” karst area is partly in the form of karst hills and is inseparable from the swamp landscape which is adjacent to the river and the coast. In the karst area of “Bukit Bangkai”, numbers of cave habitations and rock shelters have been found. In the cave habitations area, numbers of Mesolithic devices have been found, food scraps which accumulate in kitchenmidden, the distribution of cave paintings and burials. Based on the research data, it can be stated that numbers of habitation caves and niches are Mesolithic residential caves. As a Mesolithic residence cave site, it has not yet been studied about the space composition of residential cave spaces that carry out the distribution of cave habitation for the sake of residential space, kitchenmidden space, rock paintings and burial space. In this research, it stated the structuring residential cave space in conjunction with the swamps or swamplands landscape. The renewal of the results of this study is about spatial planning of Mesolithic caves habitation in swamp environments. Previous research on structuring Mesolithic caves habitation was associated with dry land landscapes, such as Mesolithic cave habitation in the Maros-Pangkep area, South Sulawesi. Thus, the renewal of this research can be used as a reference for Mesolithic cave patterns in the swamp landscape landscape environment or swamplands.

Published: January 2020

Abstract
The photodegradation of disperse violet 63 dye was investigated in aqueous solution using UV/H2O2, UV/H2O2/SnO2 and Fenton reagent. The maximum decolorization was achieved in 60 min with 50 mg l−1 of dye concentration. The suitability of each process depends upon dye concentration. The photo degradation is very effective at low dye concentration. The degradation percentage increased by enhancing initial amount of hydrogen peroxide and UV irradiation time. The influence of operational parameters like pH, H2O2 concentration, catalyst amount and dye concentration were investigated. After 60 min reaction time, the maximum decolorization of disperse violet 63 with UV/H2O2, UV/H2O2/SnO2 and Fe/H2O2 was 81%, 92.7% and 96.4% respectively. The results indicated that Fenton process had more photocatalytic activity for degradation of disperse violet 63 dye than that of UV/H2O2 and UV/H2O2/SnO2. After 60 min, the comparative decomposition order was Fe/H2O2 > UV/H2O2/SnO2 > UV/H2O2. It may be concluded that Fenton process could possibly be used for the remediation of toxic pollutants from textile effluents.

Abstract
The deprived wear resistance of AISI 1040 steel often results in higher wear rates. The best ways to upgrade their wear resistance are to introduce hard particle reinforcement to produce a metal matrix composite which can be used as a coating. In the present study Ti-6Al-4V-4B4C metal matrix composite coatings were coated on AISI 1040 steel using the magnetron sputtering process and their dry sliding wear behavior was studied at room temperature. The coating morphology was explored by SEM, XRD, FT-IR, and AFM. The constant coating thicknesses of 80 nm and 115 nm were achieved for 0.5 h and 1 h coating duration, respectively. The effects of introducing B4C on the hardness, thermal behavior, wear, and friction characteristics were studied. The nano hardness and elastic modulus were attained by AFM nanoindentation technique which showed a maximum of 21.7 GPa and 218.4 GPa, respectively. It was proven that the adding of B4C increases the thermal stability of Ti-6Al-4V-4B4C coatings as well as modifies the oxidation mechanism. It is expected that the addition of B4C will improve the thermal behavior of thin film coatings for their practical application. Wear tests were executed by ball-on-disc wear tester with E-52100 sphere as the counterface at a sliding velocity of 2 m s−1 with 3 N load. Wear rate and coefficient of friction (CoF) reduced with an increase in load and sliding distances also composite coatings exhibited higher wear resistance within entire loading conditions, hereafter suggesting that it could be a favorable substitute to other hard coatings.
