Abstract:
Preexposure to one or two elements of a compound flavor stimulus greatly reduced a neophobic reaction to the compound but did not attenuate conditioned flavor aversion in rats. Results indicated that (1) a preexposure effect on conditioned aversion to a flavor compound is not likely to be obtained if subjects initially show a strong neophobic reaction to the elements and (2) the level of neophobia at the time of conditioning has little influence on conditioned flavor aversion.

Abstract:
It might seem obvious that pain sensitivity would predict individual, inborn susceptibilities to aversive stimuli and the strength of fear-conditioned responses. Such relationships are based on the assumption that there is a close association between fear-evoked behavioral reactions and the responses to painful, aversive stimuli. However, this problem has not been systematically studied. To this end, we investigated the relationship between pain sensitivity in two pain tests (the ‘tail-flick’ and ‘flinch-jump’ tests) and a conditioned, fear-evoked, freezing response in rats. The results show t

Abstract:
Misophonia is a recently identified condition in which an individual has an acute reaction of hatred or disgust to a specific commonly occurring sound. We propose that misophonia is a form of conditioned behavior that develops as a physical reflex through Pavlovian conditioning. Although misophonia is generally considered to be a one-step reaction, in which the sound elicits rage or disgust, as well as typical autonomic responses associated with these emotions, we propose that misophonia is a two-step reaction, in which the sound elicits an aversive conditioned physical reflex, and the aversiv

Orexin and its antagonists SB-408124 or Orexin B18-28 (Sigma, USA) were used for pharmacological analysis.

In this paper we consider a preconditioning technique for the ill-conditioned systems arising from discretisations of nonsymmetric elliptic boundary value problems. The rectangular preconditioning matrix is constructed via the transfer operators between successive discretization levels of the initial problem.

Abstract:
Abstract The study of autoignition propensity in premixers for gas turbines is critical for their safe operation and design. Although premixers can be analysed using reacting Computational Fluid Dynamics (CFD) coupled with detailed autoignition chemical kinetics, it is essential to also develop methods with lower computational cost to be able to explore more geometries and operating conditions during the design process. This paper presents such an approach based on Incompletely Stirred Reactor Network (ISRN) modelling. This method uses a CFD solution of a non-reacting flow and subsequently est

Abstract:
Here the premixed Conditional Moment Closure (CMC) method is used to model the recent PIV and Raman turbulent, enclosed reacting methane jet data from DLR Stuttgart [1]. The experimental data has a rectangular test section at atmospheric pressure and temperature with a single inlet jet. A jet velocity of 90 m/s is used with an adiabatic flame temperature of 2,064 K. Contours of major species, temperature and velocities along with velocity rms values are provided. The conditional moment closure model has been shown to provide the capability to model turbulent, premixed methane flames with detai

Abstract:
Recruitment rate measurements of micro-scale particles, such as cells or microbeads, to biofunctional surfaces is difficult because factors such as uneven ligand distributions, particle collisions, variable particle fluxes, and molecular-scale surface separation distances that combine to obfuscate the ability to link the observed particle behavior with the governing nanoscale biophysics. We report the development of a hydrodynamically-conditioned micropattern catch strip assay to measure microparticle and cellular recruitment kinetics. The assay exploited patterning within microfluidic channel

Abstract:
Food is an essential to our existence but under certain conditions it could become the origin to the accumulative health damages. Technological processes as heating, chopping, mincing, grounding, promote the lipid oxidation process in muscle tissues and meat foodstuffs. Lipid oxidation occurred rapidly in turkey muscle, intermediate in duck, and slowest in chicken during frozen storage. Depletion of tocopherol during frozen storage was more rapid in turkey and duck compared to chicken. These processes developed from lipid peroxides produce many cytotoxic compounds including malondialdehyde (MD

Abstract:
Hydrogen is often considered as a promising alternative to fossil fuels, however its low boiling point and diffusivity cause a huge challenge for storage and transport. Therefore an alternative fuel like ammonia, containing 17 wt.% hydrogen with a higher boiling point, seems a very promising solution for hydrogen storage and transport. In this paper, ammonia synthesis via the most widely used Haber-Bosch process has been investigated. A computational fluid dynamics (CFD) model is developed for a lab-scale reactor, incorporating the modified Temkin kinetic model describing the complex catalytic

To enhance photocatalytic performance, Fe₂O₃ was combined with other transition-metal oxide (TMO) colloids (e.g., CuO and ZnO), which are sensitive to different regions of the solar spectrum (far visible and ultraviolet, respectively), using a ternary blending approach for compositional mixtures. For a variety of ZnO/Fe₂O₃/CuO mole ratios, the pseudo-first-order rate constant for methyl orange degradat

We study the reaction of voters to shifts in local economic conditions. Using the departure from the gold standard of US trading partners in 1931 and the US in 1933, we exploit heterogeneity in export destinations, creating local differences in expenditure-switching in US counties by isolating the aggregate effects of the monetary shocks using time fixed effects. We find significant changes in local voting behavior in response to both shocks, one originating abroad, and another domestically. The response to both shocks have similar magnitude.

Abstract:
Electrochemical measurements have been performed on polished and mill scaled steel samples. The solutions investigated have included carbonate bicarbonate mixtures of varying pH as well as solutions of neutral pH such as NS4. Results indicate that the mechanism of corrosion associated with the carbonate bicarbonate environments involves passive film formation. No such passivation is observed for solutions associated with neutral pH SCC. Electrochemical corrosion rates measured on polished steel specimens exposed to NS4 solutions in the pH range 5 to 6.8 were in the region of 5 x 10e-1 to 1 x 1
