Application of dispersive liquid-liquid microextraction and CE with UV detection for the chiral separation and determination of the multiple illicit drugs on forensic samples

A new method was developed for pre-concentration, chiral separation and determination of multiple illicit drugs on forensic samples using dispersive liquid-liquid microextraction (DLLME) and capillary electrophoresis (CE) with Ultra Violet (UV) detection. The method was based on the formation of tiny droplets of an organic extractant in the prepared sample solution using water-immiscible organic solvent (chloroform) dissolved in water-miscible organic dispersive solvent (isopropyl alcohol). The organic phase, which extracted heroin, DL-methamphetamine, DL-3, 4-methylenedioxymethamphetamine and dl-ketamine from the prepared sample solution, was separated by centrifuging. The sedimented phase was transferred into a small volume CE auto-sampler vial with 10 μL of 1% HCl methanol solution and evaporated to dryness. The residue was reconstituted in lidocaine hydrochloride aqueous solution (internal standard) and introduced by electrokinetic injection into CE. Parameters affecting extraction efficiency were investigated and optimized. Under optimum conditions, linearity of the method was 0.15-6500 μg/L for all target analytes. The LODs (S/N=3) were 0.05-0.20 μg/L. Excellent repeatability (RSD ≤ 4.4%, n=5) was achieved. The feasibility of this method was demonstrated by analyzing spiked forensic samples. To our knowledge, it is the first time to combine DLLME with CE for chiral separation and determining illicit drugs on forensic samples.     

Computational Study of Fracture Characteristics in Infant Skulls Using a Simplified Finite Element Model

Skull fracture characteristics are associated with loading conditions (such as the impact point and impact velocity) and could provide indication of abuse or accident‐induced head injuries. However, correlations between fracture characteristics and loading conditions in infant and toddler are ill‐understood. A simplified computational model representing an infant head was built to simulate skull responses to blunt impacts. The fractures were decided through a first principal strain‐based element elimination strategy. Simulation results were qualitatively compared with test data from porcine heads. This simplified model well captured the fracture pattern, initial fracture position, and direction of fracture propagation. The model also very well described fracture characteristics found in studies with human infant cadaveric specimens. A series of parametric studies was conducted, and results indicated that the parameters studied had substantial effects on fracture patterns. Additionally, the jagged shapes of sutures were associated with strain concentrations in the skull.     

“竞争化”到“竞争中立化”:市场导向标准的困境及协调路径

市场导向条件经历了从美欧到西方世界小范围达成共识的过程,竞争是演进中的核心要素,竞争与贸易领域的天然联系是市场导向条件"竞争化"的原因。市场导向标准竞争中立化诠释了竞争中立从竞争领域向区域贸易规则渗透、再向多边贸易体制扩张的过程。区域自贸协定中的竞争中立以约束政府的方式规制国有企业,未能充分虑及经贸实际,使区域化协调国有企业规则的尝试面临重重困境。对多边补贴规则的修改是市场导向标准竞争中立化的新动态,恐将放大实践中矛盾与逻辑上的不自洽。WTO危机反映了规则静态与利益动态的冲突,以恪守多边主义为前提,采竞争与贸易"双轨"并行之策,在国际、国内层面协调国有企业规则,将有助于化解市场的导向分歧。
