立法伦理的向度及其实现

立法伦理作为对法之创制活动的应然性规定,具有从＂源头＂上确保法治成为善治的重要意义。在向度上,立法伦理表现为所立之法应该符合形式合理性和实质合理性两个要件。而通过法之创制使价值形态的道德内蕴于法律之中,将一定的规范形态的道德转换为法律规范,则是立法伦理实现的两个方面。     

堆石料制样方法对其强度和变形特性影响

进行了堆石料的表面振动器压实法和振动台法制样比较试验,结果表明,表面振动器压实法所得出的试样最大干密度值明显高于振动台法.同时,针对这两种制样方法所得出的试样,开展了大型三轴得出制样方法对堆石料的强度和变形指标具有明显影响,表面振动器法对应试样的强度和变形指标均优于振动台法,其中对变形特性指标的影响更为显著.考虑到表面振动器制样过程与土石坝实际施工碾压过程近乎一致,因此,建议将表面振动器压实法作为堆石料室内最大干密度的测试方法.随着重型碾压设备在土石坝碾压施工中的普遍使用,可通过调整表面振动器底板静压力和延长振动时间来提高振动功率,尽量减小堆石料室内制样密度与现场碾压密度的差异.

Theoretical study of chlordecone and surface groups interaction in an activated carbon model under acidic and neutral conditions

Activated carbons (ACs) are widely used in the purification of drinking water without almost any knowledge about the adsorption mechanisms of the persistent organic pollutants. Chlordecone (CLD, Kepone) is an organochlorinated synthetic compound that has been used mainly as agricultural insecticide. CLD has been identified and listed as a persistent organic pollutant by the Stockholm Convention. The selection of the best suited AC for this type of contaminants is mainly an empirical and costly process. A theoretical study of the influence of AC surface groups (SGs) on CLD adsorption is done in order to help understanding the process. This may provide a first selection criteria for the preparation of AC with suitable surface properties. A model of AC consisting of a seven membered ring graphene sheet (coronene) with a functional group on the edge was used to evaluate the influence of the SGs over the adsorption. Multiple Minima Hypersurface methodology (MMH) coupled with PM7 semiempirical Hamiltonian was employed in order to study the interactions of the chlordecone with SGs (hydroxyl and carboxyl) at acidic and neutral pH and different hydration conditions. Selected structures were re-optimized using CAM-B3LYP to achieve a well-defined electron density to characterize the interactions by the Quantum Theory of Atoms in Molecules approach. The deprotonated form of surface carboxyl and hydroxyl groups of AC models show the strongest interactions, suggesting a chemical adsorption. An increase in carboxylic SGs content is proposed to enhance CLD adsorption onto AC at neutral pH conditions.     

The impact of publications from mainland China on the trends in alphabetical authorship

This paper investigates the impact of burgeoning Chinese publication on academic alphabetical authorship in the 25 subject categories that have the highest percentage of intentionally alphabetical publications. The use of alphabetical authorship is common in the social sciences and humanities, mathematics, and in some physical disciplines. Chinese academic publication has increased rapidly in recent decades (Hong Kong and Macau were excluded from the study because Hong Kong and Macau are much more internationalized than mainland China). However, authors from mainland China do not prefer alphabetical authorship. The increase in publications from mainland China lowers the probability of intentional alphabetical authorship in the natural science and technology subject categories that we examined. In some natural science and technology categories, the influence is strong. But for the social sciences and humanities, the influence is weak, due to the lower share of world publications from mainland China. Yet, in some social science and humanities subject categories such as ‘Economics’, the relative share of publications from mainland China is increasing rapidly, and the results on alphabetical authorship trends will be felt in the near future.     

基于CPTU测试的高速公路改扩建新老地基土工程特性评价研究

软土地基上进行高速公路扩建项目面临着极大的挑战,必须对新老地基土体的工程特性进行全面的评价。传统室内试验方法会对土体产生扰动,而且时间长、成本大。孔压静力触探(CPTU)技术作为一种新型的原位测试方法,可以测试锥尖阻力、侧壁摩阻力与孔隙水压力等参数,而且具有多功能、连续性、高精度等优点,在国外得到广泛的应用。采用多功能CPTU技术对京沪高速公路扩建工程新老地基土体进行原位测试,基于承载力理论与孔穴扩张理论分别解译了新老地基土体的应力历史、变形与固结特性参数。研究发现:该方法可以更准确地确定软土层的分布、厚度和深度,可为进一步分析新老路基差异沉降的计算提供科学依据,更好地指导路基拼接相互作用与地基处理的设计和施工。
