Measurement and correlation of the solubility of 1-hydroxyphenazine in different solvents at temperature from 278.5 to 333.5K

Compound of 1-hydroxyphenazine (1-OH-PHZ) is an important fungicide in agricultural production. The ranges of 1-OH-PHZ solubilities in dichloromethane at temperature of 278.5–308.5 K and in ethyl acetate, methanol and water at temperature of 278.5–333.5 K were measured using the analytical stirred flask method at barometric pressure. The color of the liquid remained unchanged throughout. The solubilities of 1-OH-PHZ in water, methanol, ethyl acetate and dichloromethane increased orderly and these solubilities also increased with increasing the temperature. The experimental data was correlated by the modified Apelblat equation. The root mean square deviations were all within 0.5% and the maximum relative average deviation was 5.2%. The calculated solubility shows a good relationship with the experimental solubility.

The public's understanding of the functionality and limitations of automatic braking in Japan

Automated driving systems are increasingly widespread in the automotive industry. To operate automobiles that are assisted by such systems, drivers must correctly understand their functionality and limitations. Hence, focusing on the rapidly spreading technology of automated braking, this study seeks to clarify the general public's understanding of automatic braking systems. A total of 210 Japanese people responded to a questionnaire regarding how automatic brakes are operated, how they work, when they disengage, and so on. The proportion of those who misunderstood the operation of the system is not especially high, but there were a certain percentage of people who had misconceptions; e.g., some believed that automatic braking could detect pedestrians or bicycles. Moreover, respondents were under the impression that drivers cannot readily disengage automatic braking systems. If they mistakenly use the automatic brake, there is a possibility of posing a risk to the road transportation system.     

公路沥青路面再生技术浅析

以当前公路行业对旧沥青路面材料的使用工艺和方法为背景，针对“沥青再生”技术和现今惯称的“沥青冷再生”技术阐述以下观点：1）真正的沥青再生技术目前只有“沥青热再生”技术，且是推广应用价值巨大的技术；2）“沥青冷再生”一说混淆了“沥青再生”的概念，把旧沥青路面材料当成普通砂石用作填充料，并将其称为“沥青冷再生”是欠准确的，且会造成巨大的资源浪费；3）应呼吁大力推广应用“沥青热再生”技术，以避免造成资源浪费。
