The role of rheological behaviour in flavour perception in model oil/water emulsions

Decreasing the fat content of a food produces changes in a range of physical, chemical and sensory properties that are important in flavour perception. The aim of this paper was to study the role of rheological behaviour in flavour perception in model oil/water emulsions, using a series of samples with different hydroxypropyl methyl cellulose (HPMC) and oil content. The composition of the emulsions was adjusted to deliver iso-release aroma in vivo and to produce samples with the same viscosity in-mouth (measured as the Kokini oral shear stress). The results showed that there was no significant difference in perceived thickness between the three samples providing further evidence that the Kokini oral sheer stress is well correlated with in-mouth thickness. However, there was a significant difference in perceived volatile fruity flavour and sweetness. Samples containing the highest oil content were perceived as significantly less fruity and sweet despite having the same volatile release and in-mouth thickness.     

Luminescence of heat-treated silicon-based polymers: promising materials for LED applications

A new strategy to obtain transparent, thermally stable, and formable photoluminescent materials for LED applications is presented. Starting from commercially available silicon-based polymers, luminescence properties are developed by means of simple heat treatment. Solid polymethylsilsesquioxane MK (Wacker-Besil^®PMS MK) and liquid poly(ureamethylvinyl)silazane Ceraset (Kion Ceraset^® PUVMS) were thermally treated between 200 and 700 °C for 2 h under Ar atmosphere. Photoluminescence properties were observed in all the samples. The structural rearrangements during thermal annealing were effective in order to red-shift the emission spectra of the untreated polymers to the visible range. The formation of dangling bonds and carbon sp², associated with the annealing procedure and confirmed by means of Electron Paramagnetic Resonance (EPR) spectroscopy and solid state Magic Angle Spinning NMR (MAS-NMR) contribute to the red-shift of the photoluminescence emissions of the polymers. After heat treatment at low temperatures (200, 300, and 400 °C), both the polymers show fluorescence in the UV range. While the polysiloxane reveals white luminescence after annealing at 500 and 600 °C, the polysilazane heat-treated at 500 °C exhibits emission in the blue-green range and is transparent. At higher temperatures the presence of free carbon counteracts the luminescence properties.     

The Multilingual World Wide Web

The advent of the World Wide Web and the ensuing growth in the popularity of the Internet have all but removed the significance of geographic borders in information sharing. The barriers that do remain are primarily linguistic and cultural. This has created a huge demand for translation. The dynamic nature of the Internet, and the unreliability of the information to be found there, means that translation needs to be carried out cheaply and quickly. This paper reviews the current state of the art in multilingual information processing in general and machine translation technology in particular. The work at Adastral Park to develop an 'Interlingual' machine translation system to assist with authoring multilingual documents is described.     

Measurements of proton conductivity in the active layer of PEM fuel cell gas diffusion electrodes

This paper reports further studies to understand and optimize the Membrane and Electrode Assembly (MEA) structure in Polymer Electrolyte Membrane Fuel Cells (PEMFCs). The effective proton conductivity in the active catalyst layer was measured as a function of its composition, which consisted of platinum catalyst on carbon support (E-Tek) and Nafion® polymer electrolyte (DuPont de Nemours). The conductivity was calculated from the resistance added to a standard MEA by the addition of an inactive composite layer in the electrolyte path between the anode and cathode. The specific conductivity of the active layer was found to be proportional to the volume fraction of Nafion® in the composite mixture, following the relationship κ^eff_H⁺≈0.078_Nafion+0.004 S cm⁻¹. Modeling studies showed that this ionic conductivity limits the utilized active layer thickness to 20–25 μm.     

The utility of the reasonable woman legal standard in hostile environment sexual harassment cases: A multimethod, multistudy examination.

The case of Ellison v. Brady (1991) was a landmark decision in establishing a new legal standard-the reasonable woman standard-for evaluating hostile environment allegations of sexual harassment and in relying, albeit indirectly, on social science evidence to support its decision. The authors review the legal standard in sexual harassment law, and the legal arguments and social science evidence underlying Ellison. The new standard could affect judgments broadly by sensitizing jurors to the situation of a female plaintiff, or it could affect judgments selectively by sensitizing only those people who might otherwise be especially insensitive to her situation. Five studies that focus on the effect of the reasonable woman standard on people's assessments of hostile environment sexual harassment indicate that the reasonable woman standard has modest, if any, effects on the judgments studied. Implications are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Household energy consumption and consumer electronics: The case of television

In recent years, there has been a dramatic rise in the number of consumer electronics in households. These new technologies and the services that support them enable new highly energy intensive behaviours. Using in-depth interview data collected from 20 households in 2006, this paper explores these energy intensive behaviours, using the example of the use of televisions. In doing so, it illustrates how the design and marketing of consumer electronics, and the services which support them, actively encourage energy intensive behaviours and how householders are reconfiguring their homes and lifestyles to fit these behaviours. This latter point is significant because, as householders change their homes and daily lives to fit energy intensive consuming behaviours, it will become increasingly difficult to encourage people to reduce their household energy consumption. This paper concludes with the implications of the research findings for policies designed to reduce household energy consumption.

Joint encoding and decoding methods for digital audio broadcasting of multiple programs

We introduce new methods for increasing the performance of multiprogram digital audio broadcast systems, e.g., satellite digital audio broadcasting. Joint multiprogram encoding is an attractive possibility for parallel broadcasting of a large number of programs. Joint coding extended over multiple audio frames in time give further improvements. The benefits of this kind of statistical multiplexing yield improved audio quality and/or higher capacity in terms of number of programs. We describe the new Joint Multiple Program Encoding Technique in the context of the perceptual audio coding (PAC) type of algorithms. We also describe methods for multi-program transmission including Equal Error Protection (EEP) as well as Unequal Error Protection (UEP) and improved error concealment for multiple program transmission. Some of the techniques described in this paper, are currently being used in satellite digital audio broadcasting in the United States.
