A Trefftz method for evaluating the T‐stress for cracks emanating from a hole in a rectangular plate
Authors: Chen Y. Z. , Wang Z. X. , Lin X. Y. 
Published: November 2007

AbstractThis paper proposes a Trefftz method for evaluating the T‐stress for cracks emanating from a hole in a rectangular plate. In this method, the displacement and the stress field are an elasticity solution, which is derived from complex potentials. The complex potentials are assumed in a series form with undetermined coefficients. After using the minimum potential energy principle, an algebraic equation for the undetermined coefficients can be formulated. The coefficients can be obtained from the equation, and the whole stress field is determined. Stress intensity factor and T‐stress can be evaluated immediately from the known solution. Merit of the suggested method is addressed. For three particular cases, R=0, R/w=0.25 and R/w=0.5, the computed results are tabulated. Copyright © 2007 John Wiley & Sons, Ltd.

Published: November 2007

AbstractAnalysis methods based on the Floquet theory have gained a large interest to compute small signal and noise effects in non‐autonomous and autonomous circuits (oscillators). A reliable and straightforward method to compute all the eigenfunctions related to the Floquet analysis is discussed here. The method has been implemented in a circuit simulator and tested on several circuits. Numerical results are presented. Copyright © 2007 John Wiley & Sons, Ltd.
Personality pathology and substance abuse in eating disorders: A longitudinal study
Authors: Thompson‐Brenner Heather , Eddy Kamryn T. , Franko Debra L. , Dorer David , Vashchenko Maryna , Herzog David B. 
Published: November 2007

AbstractObjective:Substance abuse has been shown to predict poor outcome in eating disorder (ED) samples, and prior cross‐sectional data on personality subtypes of EDs suggest that substance abuse is associated with dysregulated and possibly avoidant‐insecure subtypes. This study investigates longitudinal associations between personality and substance use.Method:Personality pathology and substance use were assessed in 213 individuals with anorexia nervosa and bulimia nervosa at baseline; substance use was assessed at regular follow‐up intervals over a 9‐year period.Results:Of the five personality factors identified, the obsessional‐sensitive and high‐functioning types were negatively associated with substance abuse at baseline, while the behaviorally dysregulated type was positively associated with substance abuse at baseline. Longitudinal associations were observed, suggesting that obsessional‐sensitive personality type was protective against the development of substance abuse. Longitudinal associations between the other personality types and substance abuse were nonsignificant after baseline substance abuse history was included as a covariate in the model.Conclusion:Substance use demonstrates cross‐sectional associations with personality style, but substance abuse history appears to be the most important predictor of future substance abuse in women with eating disorders. © 2007 by Wiley Periodicals, Inc.

Published: November 2007

AbstractThe synthesis of complexes of the general formula Cl2Ru(SIMes)(L)(3‐phenylinden‐1‐ylidene) (5, L = PCy3; 6, L = py; and 7, L = PPh3) from Cl2Ru(PR3)2(3‐phenylinden‐1‐ylidene) (2a, R = Ph; 2b, R = Cy) is reported. This family of olefin metathesis catalysts was fully characterized (1H, 13C and 31P NMR spectroscopy and elemental analysis) and provided excellent activity in the ring‐opening metathesis polymerization of 1,5‐cyclooctadiene and the ring‐closing metathesis of diethyl diallylmalonate. Comparison with the corresponding benzylidene‐containing catalysts, 1a,c and 8b, established the decisive role of the carbene ligand on the procedure of the reaction and led to the observation of an unusual catalytic phenomenon, here called “self‐inhibition”.(© Wiley‐VCH Verlag GmbH & Co.

“Furan Endwise Peeling” of Celluloses: Mechanistic Studies and Application Perspectives of a Novel Reaction
Authors: Yoneda Yuko , Krainz Karin , Liebner Falk , Potthast Antje , Rosenau Thomas , Karakawa Makoto , Nakatsubo Fumiaki 
Published: November 2007

AbstractThe mechanism of a novel reaction type, the “furan endwise peeling” reaction, has been studied. Making extensive use of experiments on model compounds, the structural prerequisites to the reaction were found to be a 2‐hydroxpyran β‐glycosidically linked to a 2‐(2‐furyl)ethyl moiety. Proceeding from the reducing end of the celluloses, the reaction causes the one‐by‐one loss of anhydroglucose units (AGUs) which are concomitantly converted into 2‐(tetrahydroxybutyl)furans (4) by co‐reacting with 1,3‐dicarbonyl compounds such as ethyl acetoacetate (1). The key step of the reaction is the formation of a furan at the reducing end followed by the attack of the 2‐OH group of the last‐but‐one AGU at this terminal furan. The intermediate, unstable dioxepane fragments by cleavage of the glycosidic bond. The terminal AGU is released as a substituted furan, the “new” reducing end reacting immediately with the 1,3‐dicarbonyl component to form a new terminal furan which, in turn, undergoes the same cycle. The “furan endwise peeling” reaction represents an interesting way to convert cellulosic biomass by an easy procedure into substituted furans that are valuable fine chemicals with multiple uses.(© Wiley‐VCH Verlag GmbH & Co.

Reactions of Lithium Silylcuprates with Pyrazolium and Indazolium Salts
Authors: González‐Nogal Ana M. , Calle Mariola , Cuadrado Purificación 
Published: November 2007

AbstractAlthough pyrazolium salts have been shown to be unreactive toward lithium carbocuprates, these substrates were opened by lithium silylcuprate reagents to give versatile N‐silylated β‐enaminoimines stabilized by coordination of the silyl group with both nitrogen atoms. In contrast, the behaviour of indazolium salts on treatment with the same reagents is more complex. Depending on the substitution patterns of the indazolium salts, the nature of the silylcuprate and even on the temperature, we obtained 3‐silylindazolines and other interesting products resulting either from the opening of the heterocyclic ring or from modification by its opening/closing.(© Wiley‐VCH Verlag GmbH & Co.

Published: November 2007

AbstractAnodic stripping voltammetry is useful instrumental method for trace element determination in biological materials. It is however extremely demanding to the quality of the sample preparation process. The high‐pressure microwave assisted digestion seems to meet its requirements. The differential pulse anodic stripping voltammetry technique was used for determination of cadmium, copper, lead and zinc in certified reference materials both of plant and of animal origin to prove the analytical properties of such sample preparation method. The found concentrations have been in satisfactory agreement with the certified values. The elaborated digestion procedure is greatly universal and has required accuracy and precision.
A micropillar‐integrated smart microfluidic device for specific capture and sorting of cells

Published: November 2007

AbstractAn integrated smart microfluidic device consisting of nickel micropillars, microvalves, and microchannels was developed for specific capture and sorting of cells. A regular hexagonal array of nickel micropillars was integrated on the bottom of a microchannel by standard photolithography, which can generate strong induced magnetic field gradients under an external magnetic field to efficiently trap superparamagnetic beads (SPMBs) in a flowing stream, forming a bed with sufficient magnetic beads as a capture zone. Fluids could be manipulated by programmed controlling the integrated air‐pressure‐actuated microvalves, based on which in situ bio‐functionalization of SPMBs trapped in the capture zone was realized by covalent attachment of specific proteins directly to their surface on the integrated microfluidic device. In this case, only small volumes of protein solutions (62.5 nL in the capture zone; 375 nL in total volume needed to fill the device from inlet A to the intersection of outlet channels F and G) can meet the need for protein! The newly designed microfluidic device reduced greatly chemical and biological reagent consumption and simplified drastically tedious manual handling. Based on the specific interaction between wheat germ agglutinin (WGA) and N‐acetylglucosamine on the cell membrane, A549 cancer cells were effectively captured and sorted on the microfluidic device. Capture efficiency ranged from 62 to 74%. The integrated microfluidic device provides a reliable technique for cell sorting.
On‐column conductivity detection in capillary‐chip electrophoresis
Authors: Wu Zhi‐Yong , Fang Fang , Josserand Jacques , Girault Hubert H 
Published: November 2007

AbstractOn‐column conductivity detection in capillary‐chip electrophoresis was achieved by actively coupling the high electric field with two sensing electrodes connected to the main capillary channel through two side detection channels. The principle of this concept was demonstrated by using a glass chip with a separation channel incorporating two double‐Ts. One double‐T was used for sample introduction, and the other for detection. The two electrophoresis electrodes apply the high voltage and provide the current, and the two sensing electrodes connected to the separation channel through the second double‐T and probe a potential difference. This potential difference is directly related to the local resistance or the conductivity of the solution defined by the two side channels on the main separation channel. A detection limit of 15 μM (600 ppb or 900 fg) was achieved for potassium ion in a 2 mM Tris‐HCl buffer (pH 8.7) with a linear range of 2 orders of magnitude without any stacking. The proposed detection method avoids integrating the sensing electrodes directly within the separation channel and prevents any direct contact of the electrodes with the sample. The baseline signal can also be used for online monitoring of the electric field strength and electroosmosis mobility characterization in the separation channel.

Complex wastewater treatment using an anaerobic baffled reactor
Authors: Krishna G.V.T. Gopala , Kumar Pramod , Kumar Pradeep 
Published: November 2007

AbstractAnaerobic treatment of a low strength complex wastewater made of cellulose and sucrose (40:60) was studied in a 10 L capacity laboratory scale anaerobic baffled reactor (ABR). It was operated at hydraulic retention times (HRTs) of 20, 15, 10, 8, and 6 h. Corresponding organic loading rates (OLRs) were 0.6, 0.8, 1.2, 1.5, and 2 kg COD/m3d. At every HRT (or OLR), pseudo steady state was achieved. Even at maximum OLR of 2 kg COD/m3d, total COD and BOD removals exceeded 88%. Compartmentwise profiles of parameters show that larger the OLR, more number of initial compartments play significant role in the removal of COD (or BOD). The volatile fatty acids profile demonstrated that hydrolysis and acidogensis are the main biochemical activities in the initial few compartments. On the basis of the tracer study, dead space in ABR was found to range from 23 to 34%. The flow pattern in the ABR could be classified as an intermediate between plug and perfectly mixed flows. © 2007 American Institute of Chemical Engineers Environ Prog, 2007
