Who Fears Strangers and Spiders: Political Ideology and Feeling Threatened

In this study, I evaluated the correlations between threat sensitivities and political ideology. Two hypotheses were tested. First, I hypothesized that conservatives would have higher social threat sensitivity than liberals, with social threat defined as a threat dependent on outgroup or social actions (Barclay & Benard, 2020). Second, I hypothesized that conservatives would have higher disgust sensitivity than liberals. To test these and related hypotheses I used a 2018 Qualtrics national demographically representative sample that included 1031 participants. To operationalize threat sensitivity, I used items asking participants to rate how threatened they felt by various fears. These individual items were then grouped by threat type: social, asocial, and disgust sensitive. Political ideology was operationalized through a Wilson-Patterson Conservatism Scale of issue positions. Conservatives were also broken into sub-groups- economic, social, and securitarian using the relevant Wilson Patterson items. My analysis did not find support for the initial hypotheses. Instead, compared to liberals, conservatives reported being less fearful of all fear types. Further analysis, however, revealed that only economic conservatives were less fearful of threats. In other words, social conservatives and securitarian conservatives were not LESS fearful than liberals. As such, this study provides the basis for further research regarding threat sensitivity and political identification

Analysis of high temperature steam oxidation of superheater steels used in coal fired boilers

The present work compares the behaviour of four steels: (T23, T92, T347HFG, Super304H) in the temperature range 600–750 °C. This study focuses on the analysis of the oxidation kinetics in terms of mass change, metal loss and thickness change of the selected materials. In order to understand the differences in oxidation rates between the selected steels, the impact of chromium and the alloying elements were considered in this work. The obtained results show that the impact of alloying elements differs with exposure conditions and importance of the synergy effect

Impact specimen geometry on T23 and TP347HFG steels behaviour during steam oxidation at harsh conditions

Ferritic T23 steel and austenitic TP347HFG steel have been studied with an emphasis on understanding the impact of specimen geometry on their steam oxidation behaviour. The selected materials were tested over a wide range of temperatures from 600 to 750°C. The tests were carried out in 100% steam conditions for 1000 hours. The tests indicated that the ‘curved-shaped’ specimens show slower mass gain, scale ticking and void nucleation rates than ‘bridge-shaped’ specimens (with flat and convex surfaces combined). Furthermore, a bridge TP347HFG sample showed the formation of lower amount of flaky oxide at 750°C.We would like to acknowledge the support of The Energy Programme, which is a Research Councils UK cross council initiative led by EPSRC and contributed to by ESRC, NERC, BBSRC and STFC, and specifically the Supergen initiative (Grants GRyS86334y01 and EPyF029748) and the following companies; Alstom Power Ltd., Doosan Babcock, E.ON, National Physical Laboratory, Praxair Surface Technologies Ltd, QinetiQ, Rolls-Royce plc, RWE npower, Siemens Industrial Turbomachinery Ltd. and Tata Steel, for their valuable contributions to the project

Epistemic Function and Ontology of Analog and Digital Images

The important epistemic function of photographic images is their active role in construction and reconstruction of our beliefs concerning the world and human identity, since we often consider photographs as presenting reality or even the Real itself. Because photography can convince people of how different social and ethnic groups and even they themselves look, documentary projects and the dissemination of photographic practices supported the transition from disciplinary society to the present-day society of control. While both analog and digital images are formed from the same basic materia, the ways in which this matter appears are distinctive. In the case of analog photography, we deal with physical and chemical matter, whereas with digital images we face electronic matter. Because digital photography allows endless modification of the image, we can no longer believe in the truthfulness of digital images

Introduction to Arnold Berleant’s Perspective

The selection of papers in the 6th Volume of the ESPES journal focuses on the development, analyses and critique of Arnold Berleant’s ideas on aesthetic engagement, social aesthetics, negative aesthetics, and environmental aesthetics. These issues are approached by researchers from various continents showing the inspirational potential of Berleant’s perspective, inviting metaphors, opening paths for individual development in the field of art philosophy and aesthetics

Existence theorem and blow-up criterion of the strong solutions to the Magneto-micropolar fluid equations

In this paper we study the magneto-micropolar fluid equations in $\R^3$, prove the existence of the strong solution with initial data in $H^s(\R^3)$ for $s> {3/2}$, and set up its blow-up criterion. The tool we mainly use is Littlewood-Paley decomposition, by which we obtain a Beale-Kato-Majda type blow-up criterion for smooth solution $(u,\omega,b)$ which relies on the vorticity of velocity $\nabla\times u$ only.Comment: 19page

Introgression of Brown Norway \u3cem\u3eCYP4A\u3c/em\u3e Genes onto the Dahl Salt-Sensitive Background Restores Vascular Function in SS-5\u3csup\u3eBN\u3c/sup\u3e Consomic Rats

The present study tested the hypothesis that the Dahl SS (salt-sensitive) rat has vascular dysfunction due, in part, to the up-regulation of the CYP4A/20-HETE (cytochrome P450 ω-hydroxylase 4A)/20-hydroxyeicosatetraenoic acid) system. To assess the role of vascular 20-HETE, SS rats were compared with SS-5BN consomic rats, carrying CYP4A alleles on chromosome 5 from the normotensive BN (Brown Norway) introgressed on to the SS genetic background. Cerebral arteries from SS-5BN rats had less CYP4A protein than arteries from SS rats fed either NS (normal-salt, 0.4% NaCl) or HS (high-salt, 4.0% NaCl) diet. ACh (acetylcholine)-induced dilation of MCAs (middle cerebral arteries) from SS and SS-5BN rats was present in SS-5BN rats fed on either an NS or HS diet, but absent in SS rats. In SS rats fed on either diet, ACh-induced dilation was restored by acute treatment with the CYP4A inhibitor DDMS (N-methyl-sulfonyl-12,12-dibromododec-11-enamide) or the 20-HETE antagonist 20-HEDE [20-hydroxyeicosa-6(Z),15(Z)-dienoic acid]. The restored response to ACh in DDMS-treated SS rats was inhibited by L-NAME (NGnitro-L-arginine methyl ester) and unaffected by indomethacin or MS-PPOH [N-methylsulfonyl-6-(2-propargyloxyphenyl)hexanamide]. Vascular relaxation responses to the NO donor C5FeN6Na2O were intact in both SS and SS-5BN rats and unaffected by the acute addition of DDMS, indicating that the vascular dysfunction of the SS rat is due to a reduced bioavailability of NO instead of failure of the VSMCs (vascular smooth muscle cells) to respond to the vasodilator. Superoxide levels in cerebral arteries of SS-5BN rats [evaluated semi-quantitatively by DHE (dihydroethidium) fluorescence] were lower than those in the arteries of SS rats. These findings indicate that SS rats have an up-regulation of the CYP4A/20-HETE pathway resulting in elevated ROS (reactive oxygen species) and reduced NO bioavailability causing vascular dysfunction

Preparation and characterization of polymers imprinted molecularly with ibuprofen and nitrobenzene

In this work molecularly imprinted polymer (MIP) which can be later used for SPME improvement were prepared. Polymerization reaction was initiated in six different ways and for this purpose six different solvents as porogens were used. Prepared MIP’s were stable in temperature range 160–200°C. Pore sizes and BET surface were characterized by sorption of nitrogen at liquid nitrogen temperature. On the contrary to most MIPs, the studied MIPs were strictly nanoporous i.e. most of total pore volume was attributed to pores ranging from 3 to 1.0 nm in diameter. BET surface area exceeded even 300 m2/g. Basic conditions of the MIPs synthesis have been optimized with particular respect to type of solvent and polymerization initiator which are basic factors influencing the ability of the MIP towards adsorption of ibuprofen/nitrobenzene
