The Impact and Countermeasures of New Tax Policy for Cross-Border E-Commerce in China
Authors: Shi Bowen , Gao Xiang , Jia Liangting , Xiangnan Guo  
Published: May 2024

The implementation of the Announcement on Issues concerning the Regulation of Retail Import and Export Commodities through Cross-Border E-commerce marked the end of a tax-free era of cross-border e-commerce in China. The new policies (known in this paper as the New Deal) have had a profound effect on enterprises, consumers and overseas purchasing agents engaged in cross-border e-commerce transactions. Empirical data from eight cross-border e-commerce pilot cities (Shanghai, Chongqing, Guangzhou, Shenzhen, Zhengzhou, Ningbo, Hangzhou and Dongguan) were studied. Results from the research into these pilot cities show that: (1) the development of crossborder e-commerce among those cities is unbalanced; (2) the New Deal has not resulted in a significant impact on import and export behaviours; and (3) the tax burden of crossborder e-commerce enterprises has increased considerably since the implementation of the New Deal. Based on these results, for the purpose of promoting the development of cross-border e-commerce, the following recommendations are made: (1) improve the policies and regulations to create an environment that supports e-commerce development; (2) facilitate the port cooperation mechanism and promote the construction of a customs single window; (3) strengthen top-level design and improve the coordination and management between relevant authorities; and (4) encourage enterprises to follow market trends and focus on product innovation and market expansion.

Published: April 2010

AbstractThis review outlines developments in the growth of crystalline oxides on the ubiquitous silicon semiconductor platform. The overall goal of this endeavor is the integration of multifunctional complex oxides with advanced semiconductor technology. Oxide epitaxy in materials systems achieved through conventional deposition techniques is described first, followed by a description of the science and technology of using atomic layer‐by‐layer deposition with molecular beam epitaxy (MBE) to systematically construct the oxide–silicon interface. An interdisciplinary approach involving MBE, advanced real‐space structural characterization, and first‐principles theory has led to a detailed understanding of the process by which the interface between crystalline oxides and silicon forms, the resulting structure of the interface, and the link between structure and functionality. Potential applications in electronics and photonics are also discussed.

A study of Cu(I)‐ethylene complexation for olefin–paraffin separation
Authors: Chen Joseph , Eldridge R. Bruce , Rosen Evelyn L. , Bielawski Christopher W. 
Published: April 2010

AbstractThe current cryogenic distillation technology used for olefin–paraffin separation incurs extensive capital and operating costs. An alternative olefin–paraffin separation process, based on reactive absorption, could yield significant cost reductions. The research efforts described herein explored the structural characteristics of an NMP‐CuCl‐aniline absorption solution with ethylene to aid future development of olefin–paraffin separation systems. Solution IR and 1H NMR spectroscopy suggested weak and labile Cu(I)‐ethylene and Cu(I)‐aniline coordination, which point to the coexistence of multiple structures in solution. Experiments also revealed solvent‐dependent and temperature‐dependent coordination. The agreement of the collected spectral data with literature implied single ethylene coordination, whereas the Cl− ion likely remained coordinated with Cu(I). Solvent interference prohibited detailed investigation of IR spectra, but 1H NMR spectroscopy showed more promise as an analytical technique for the NMP‐CuCl‐aniline‐ethylene system. Finally, a tradeoff appears to exist between ethylene capacity and complex stability, and thus, an optimal ligand must be found that balances these two competing needs. © 2010 American Institute of Chemical Engineers AIChE J, 2011
Meta‐analysis of the heterogeneity in association of DRD4 7‐repeat allele and AD/HD: Stronger association with AD/HD combined type
Authors: Smith Taylor F. 
Published: April 2010

AbstractThe purpose of this meta‐analysis was to examine whether association studies between attention deficit/hyperactivity disorder (AD/HD) and the dopamine receptor 4 gene 7‐repeat (DRD4 7R) allele vary systematically based on study characteristics. A total of 27 empirical studies with 28 distinct samples using either case–control or family‐based association analyses were included. Consistent with previous meta‐analytic work [Gizer et al. (2009), Hum Genet 126:51–90], the DRD4 7R allele was associated with AD/HD across studies (OR = 1.33; 95% CI = 1.16–1.53, z = 4.04, P = 0.00005) and there was significant systematic variability among studies (Q = 54.24; P = 0.001; I2 = 50.22). To account for the variability among studies, sample and study level covariates were examined. No differences in overall effect size emerged between family‐based and case–control studies. However, the risk allele frequency in the control population accounted for a significant portion of the variance in overall effect size within case–control studies. In addition, evidence for the association between the DRD4 7R allele and distinct AD/HD subtypes emerged across family‐based and case–control studies. The proportion of AD/HD, combined type individuals within the AD/HD sample was associated with a significant increase in the magnitude of association between the DRD4 7R allele and AD/HD. Conversely, an increase in the proportion of AD/HD, predominantly inattentive type individuals within the AD/HD sample was associated with a decrease in study effect size. Implications regarding AD/HD etiological and phenotypic heterogeneity are discussed. © 2010 Wiley‐Liss, Inc.
Alkyl exchange reaction between dialkylzinc compounds and methylaluminoxane and the effect on propylene polymerization
Authors: Zhang Chuanhui , Huang Hua‐Hua , Niu Hui , Dong Jin‐Yong 
Published: April 2010

AbstractAlkyl exchange reaction between dialkylzinc compounds and vacuum‐dried methylaluminoxane (MAO) was investigated. 1H NMR shows a clear and direct proof of alkyl exchange reaction between ZnEt2 and trimethylaluminum associated with MAO. Detailed analysis of polymers produced in the presence of dialkylzinc compounds gave other indirect but equally strong evidence of alkyl exchange. Therefore, care must be taken to investigate dialkylzinc‐based chain transfer reaction in combination with a precatalyst and MAO. Copyright © 2010 John Wiley & Sons, Ltd.
Beurteilung und Instandsetzung von chloridinduzierten Korrosionsschäden an Spannbetonbindern einer Filteranlage für Trinkwasser
Authors: Gehlen Christoph , Knab Franz , Ullmann Stefan 
Published: April 2010

AbstractAn der Filteranlage des Wasserwerks Langenau wurden Risse und Abplatzungen im Bereich der Spannköpfe von Spannbetonbindern festgestellt. Erste Untersuchungen zeigten, dass chloridinduzierte Korrosion vorlag. Da konstruktionsbedingt insbesondere die Spannbewehrung betroffen war, wurde eine eingehende Untersuchung der Schäden veranlasst, welche das Ziel hatte, neben der Entwicklung eines geeigneten Instandsetzungskonzepts auch Aussagen zur Resttragfähigkeit der Spannglieder zu treffen. Die Untersuchungen vor Ort offenbarten neben den Korrosionsschäden an den Spannköpfen auch ausgeprägte Verpressfehler im Bereich der Festanker. Nachfolgend werden die Herangehensweise an die Problematik, die durchgeführten Untersuchungen und die dabei angewandten Untersuchungsmethoden, das entwickelte Instandsetzungskonzept (Konservierung des Ist‐Zustands) und die Schlussfolgerungen zur Resttragfähigkeit erläutert. Auf Grundlage der Ergebnisse konnte die Korrosionsursache (Chloridquelle) eindeutig bestimmt und die Standsicherheit der Halle nachgewiesen werden. Die Halle wurde zwischenzeitlich instand gesetzt und wird zukünftig auf Wunsch des Bauherrn durch regelmäßige Überwachung auf neuerliche Auffälligkeiten kontrolliert.Assessment and Repair of Chloride Induced Corrosion on the Prestressed Concrete Binder of a Filtration System for Drinking WaterOn the filter system of the Langenau water work, cracks and spalling were identified in the area of the clamping chucks of the prestressed concrete binder. Initial investigations showed, that chloride induced corrosion was present. Since especially the prestressed reinforcement was affected, an expert assessment of the damages was conducted, which had the objective of, along with the development of an appropriate repair plan, making statements regarding the residual strength of the tendons. In addition to the corrosion of the clamping heads, the investigations revealed a distinctive injection defect in the area of the fixed anchor. Consecutively, the approach to the problem, the conducted investigations and the investigation methods used, the developed repair concept (conservation of the actual status) and the conclusions on the remaining carrying capacity are explained. Based on the results, the cause of the corrosion (the source of the chloride) could be clearly determined and the stability of the hall could be verified. In the meantime, the hall has since been repaired and in the future will be controlled through regular monitoring of noticeable problems at the request of the client.
Anaerobic digestion as final step of a cellulosic ethanol biorefinery: Biogas production from fermentation effluent in a UASB reactor—pilot‐scale results
Authors: Uellendahl H. , Ahring B.K. 
Published: April 2010

AbstractIn order to lower the costs for second generation bioethanol from lignocellulosic biomass anaerobic digestion of the effluent from ethanol fermentation was implemented using an upflow anaerobic sludge blanket (UASB) reactor system in a pilot‐scale biorefinery plant. Both thermophilic (53°C) and mesophilic (38°C) operation of the UASB reactor was investigated. At an OLR of 3.5 kg‐VS/(m3 day) a methane yield of 340 L/kg‐VS was achieved for thermophilic operation (53°C) while 270 L/kg‐VS was obtained under mesophilic conditions (38°C). For loading rates higher than 5 kg‐VS/(m3 day) the methane yields were, however, higher under mesophilic conditions compared to thermophilic conditions. The conversion of dissolved organic matter (VSdiss) was between 68% and 91%. The effluent from the ethanol fermentation showed no signs of toxicity to the anaerobic microorganisms. However, a high content of suspended matter reduced the degradation efficiency. The retention time of the anaerobic system could be reduced from 70 to 7 h by additional removal of suspended matter by clarification. Implementation of the biogas production from the fermentation effluent accounted for about 30% higher carbon utilization in the biorefinery compared to a system with only bioethanol production.

Mechanism of initial rapid rate retardation in cellobiohydrolase catalyzed cellulose hydrolysis
Authors: Jalak Jürgen , Väljamäe Priit 
Published: April 2010

AbstractDespite intensive research, the mechanism of the rapid retardation in the rates of cellobiohydrolase (CBH) catalyzed cellulose hydrolysis is still not clear. Interpretation of the hydrolysis data has been complicated by the inability to measure the catalytic constants for CBH‐s acting on cellulose. We developed a method for measuring the observed catalytic constant (kobs) for CBH catalyzed cellulose hydrolysis. It relies on in situ measurement of the concentration of CBH with the active site occupied by the cellulose chain. For that we followed the specific inhibition of the hydrolysis of para‐nitrophenyl‐β‐D‐lactoside by cellulose. The method was applied to CBH‐s TrCel7A from Trichoderma reesei and PcCel7D from Phanerochaete chrysosporium and their isolated catalytic domains. Bacterial microcrystalline cellulose, Avicel, amorphous cellulose, and lignocellulose were used as substrates. A rapid decrease of kobs in time was observed on all substrates. The kobs values for PcCel7D were about 1.5 times higher than those for TrCel7A. In case of both TrCel7A and PcCel7D, the kobs values for catalytic domains were similar to those for intact enzymes. A model where CBH action is limited by the average length of obstacle‐free way on cellulose chain is proposed. Once formed, productive CBH–cellulose complex proceeds with a constant rate determined by the true catalytic constant. After encountering an obstacle CBH will “get stuck” and the rate of further cellulose hydrolysis will be governed by the dissociation rate constant (koff), which is low for processive CBH‐s.

Genetic engineering approach for the production of rhamnosyl and allosyl flavonoids fromEscherichia coli
Authors: Simkhada Dinesh , Lee Hei Chan , Sohng Jae Kyung 
Published: April 2010

AbstractThe main functions of glycosylation are stabilization, detoxification and solubilization of substrates and products. To produce glycosylated products,Escherichia coliwas engineered by overexpression of TDP‐L‐rhamnose and TDP‐6‐deoxy‐D‐allose biosynthetic gene clusters, and flavonoids were glycosylated by the overexpression of the glycosyltransferase gene fromArabidopsis thaliana. For the glycosylation, these flavonoids (quercetin and kaempferol) were exogenously fed to the host in a biotransformation system. The products were isolated, analyzed and confirmed by HPLC, LC/MS, and ESI‐MS/MS analyses. Several conditions (arabinose, IPTG concentration, OD600, substrate concentration, incubation time) were optimized to increase the production level. We successfully isolated approximately 24 mg/L 3‐O‐rhamnosyl quercetin and 12.9 mg/L 3‐O‐rhamnosyl kaempferol upon feeding of 0.2 mM of the respective flavonoids and were also able to isolate 3‐O‐allosyl quercetin. Thus, this study reveals a method that might be useful for the biosynthesis of rhamnosyl and allosyl flavonoids and for the glycosylation of related compounds. Biotechnol.

Published: April 2010

AbstractBackgroundAlthough patients with liver cirrhosis are supposed to tolerate ischaemia–reperfusion poorly, the exact impact of intermittent inflow clamping during hepatic resection of cirrhotic compared with normal liver remains unclear.MethodsIntermittent Pringle's manoeuvre was applied during minor hepatectomy in 172 patients with a normal liver, 59 with chronic hepatitis and 97 with liver cirrhosis. To assess hepatic injury, delta (D)-aspartate aminotransferase (AST) and D-alanine aminotransferase (ALT) (maximum level minus preoperative level) were calculated. To evaluate postoperative liver function, postoperative levels of total bilirubin, albumin and cholinesterase (ChE), and prothrombin time were measured.ResultsSignificant correlations between D-AST or D-ALT and clamping time were found in each group. The regression coefficients of the regression lines for D-AST and D-ALT in patients with normal liver were significantly higher than those in patients with cirrhotic liver. Irrespective of whether clamping time was 45 min or less, or at least 60 min, D-AST and D-ALT were significantly lower in patients with cirrhosis than in those with a normal liver. Parameters of hepatic functional reserve, such as total bilirubin, prothrombin time, albumin and ChE, were impaired significantly after surgery in patients with a cirrhotic liver.ConclusionPatients with liver cirrhosis had a smaller increase in aminotransferase levels following portal triad clamping than those with a normal liver. However, hepatic functional reserve in those with a cirrhotic liver seemed to be affected more after intermittent inflow occlusion.
