Rubber Filler

A comparative study focusing on the visco–elastic properties of two series of carbon black filled composites with natural rubber (NR) and its blends with butadiene rubber (NR-BR) as matrices is reported. Strain sweeps at different temperatures are performed. Filler network-related contributions to reinforcement (ΔG′) are quantified by the classical Kraus equation while a modified Kraus equation is used to quantify different contributions to dissipation (ΔGD″, ΔGF″). Results indicate that the filler network is visco-elastic in nature and that it is causing a major part of the composite dissipation at small and intermediate strain amplitudes. The temperature dependence of filler network-related reinforcement and dissipation contributions is found to depend significantly on the rubber matrix composition. We propose that this is due to differences in the chemical composition of the glassy rubber bridges connecting filler particles since the filler network topology is seemingly not significantly influenced by the rubber matrix for a given filler content. The underlying physical picture explains effects in both dissipation and reinforcement. It predicts that these glassy rubber bridges will soften sequentially at temperatures much higher than the bulk Tg of the corresponding rubber. This is hypothetically due to rubber–filler interactions at interfaces resulting in an increased packing density in the glassy rubber related to the reduction of free volume. From a general perspective, this study provides deeper insights towards the molecular origin of reinforcement and dissipation in rubber composites.

General Perspective

Abstract The general perspective in pragmatics research on stand-up comedy is that the comedian co-produces humor with the audience. In this paper, I argue that the stand-up comedian’s communicative behavior is also partly rooted in egocentrism. To achieve this, I adopted a sociocognitive approach to intention and egocentrism in analyzing a routine that was performed in Chicago by Okey Bakassi, a Nigerian stand-up comedian. I operationalize egocentrism as one of the humor strategies of the comedian. While focusing on the propositional content of the comedian’s utterances, the analysis revealed strategies like privatization, ad hoc concept formation and ad hoc coherence, which the comedian used in individualizing the prior common ground to generate the needed incongruity for humor in the performance sphere.

General Perspective

The fashion industry being one of the most polluting industries in the world means that it is an industry with an immense potential for change. Consumers are central and are closely intertwined with how companies act. This research reflects consumer perspectives and practices towards the topic of sustainability implemented in the fashion industry. The relevance of sustainability in the fashion industry and the key role of consumers in its implementation are undeniable and confirmed by consumers in a representation of general awareness and concern, despite not always being translated into actual practices. A qualitative research methodology, followed by a set of interviews conducted with consumers, revealed that the great majority are implementing a variety of practices when making their buying choices towards fashion items. Barriers such as lack of education, information, knowledge and transparency were identified, and this aspect was shared by consumers as a reason why they are not motivated to make more conscious decisions. Companies should educate consumers from a general perspective and focus on the group of consumers that are not implementing sustainability in the fashion industry in their buying choices, as they represent the potential for the future.

Abstract An accidental U(1) Peccei-Quinn (PQ) symmetry automatically arises in a class of SO(10) unified theories upon gauging the SU(3)f flavour group. The PQ symmetry is protected by the ℤ4 × ℤ3 center of SO(10) × SU(3)f up to effective operators of canonical dimension six. However, high-scale contributions to the axion potential posing a PQ quality problem arise only at d = 9. In the pre-inflationary PQ breaking scenario the axion mass window is predicted to be ma ∈ [7 × 10−8, 10−3] eV, where the lower end is bounded by the seesaw scale and the upper end by iso-curvature fluctuations. A high-quality axion, that is immune to the PQ quality problem, is obtained for ma ≳ 2 0.02 eV. We finally offer a general perspective on the PQ quality problem in grand unified theories.

General Perspective

The aim of the present overview article is to raise awareness of an essential aspect that is usually not accounted for in the modelling of electron transport for focused-electron-beam-induced deposition (FEBID) of nanostructures: Surface excitations are on the one hand responsible for a sizeable fraction of the intensity in reflection-electron-energy-loss spectra for primary electron energies of up to a few kiloelectronvolts and, on the other hand, they play a key role in the emission of secondary electrons from solids, regardless of the primary energy. In this overview work we present a general perspective of recent works on the subject of surface excitations and on low-energy electron transport, highlighting the most relevant aspects for the modelling of electron transport in FEBID simulations.
