Sonic food words influence the experience of beverage healthfulness

The consumption of healthful foods is relevant for the well-being of society. However, understanding healthfulness may be difficult because, in some cultures (i.e., the U.S.), individuals assume that unhealthy equals tasty, an association that does not hold in other contexts (i.e., France). Auditory cues could serve to inform consumers about the expected experience with food and thus could signal the sensory experience of a healthy product. This research contributes to the literature on the use of sound symbolism for analysis of the influence of onomatopoeias as packaging information that influences the expected healthfulness of a bottled drink. The study is a 4 × 4 mixed-model experiment. Grouping was done according to onomatopoeia variables as follows: “Fizz,” “Glup,” “Ahhh,” and control. Beverage color, a within-subject variable, was grouped as green, yellow, red, and control. Results show that the healthful concept is defined in two dimensions: fulfilling and light. Onomatopoeias motivated the experience of a less fulfilling beverage, which had the strongest effect on “Fizz” condition. For the light dimension, “Ahhh” diminishes the perception of light, thus creating the idea that the drink is high in calories. This study reaches out to food industries on the need to find the most consistent and pleasurable sound associated with their products. This will enable food industries to provide information to consumers as well as ascertain how much they enjoy the product.     

Homogeneous non-equilibrium two-phase choked flow modeling

The estimation of the release conditions is critical input to subsequent risk assessment accident analysis. To this respect a new homogeneous non-equilibrium two-phase model is proposed to simulate the depressurization from stagnation conditions leading to the bubbly flow regime. The proposed model, being intermediate between HEM (homogeneous equilibrium) and HFM (homogeneous frozen) models, presents no discontinuity in the liquid phase depressurization path gradient and therefore no discontinuity in sound speed. The proposed model is successfully validated against the NASA hydrogen critical flow experiments and compared against predictions from both HEM and HFM, using hydrogen physical properties from NIST. An increase of the pressure difference between stagnation and the intersection of isentropic with saturation line leads to increase of the choked mass flux, decrease of the throat to stagnation pressure ratio, decrease of the liquid superheat and decrease of the vapor quality. The proposed model was found to overestimate the experimental throat mass fluxes by no more than 10% and underestimate the experimental throat to stagnation pressure ratios by no more than 50%, while predicted liquid superheat values range from 3.8 to 11% of the saturation temperature. Deviations between models were found to increase for low values of the pressure difference parameter, where non-equilibrium effects become more important. Under these conditions the throat mass flux is underestimated by maximum 20% by HEM and overestimated up to 32% by HFM, while the throat to stagnation pressure ratio is overestimated by up to 72% and underestimated by 80% respectively.     

声发射技术在预测预报煤与瓦斯突出方面的研究

煤与瓦斯突出是煤矿最严重的自然灾害之一。为了尽可能减轻其危害．多年来我国在突出危险性预测方面开展了大量的工作，特别是在应用工作面钻孔参数预测突出的方法和仪器装备方面都有明显的进展，取得了一些实用成果。但这种预测方法仍有一定的工程量（如需要打钻孔等），每次预测作业时间需要4～5h，不仅对生产有一定影响。而且有一定的危险．不能满足现场需要。

物理环境设计对人性化空间塑造的重要意义

良好的空间物理环境是塑造全面人性化空间环境的前提条件.一个空间环境首先得具备舒适的热、声、光环境,满足了人们最基本的生理需求,这个空间环境才能留得住人,才具有人气,从而才能体现人性化.但是我们在创造空间环境的时候往往忽视了物理环境对人性化空间塑造的重要作用.该文通过分析物理环境对人的影响,指出物理环境优化设计对人性化空间环境塑造的重要意义.
