ABSTRACTObjective: To characterize the performance of glucose meter test strips using simulated dynamic temperature and humidity disaster conditions.Methods: Glucose oxidase- and glucose dehydrogenase-based test strips were dynamically stressed for up to 680 hours using an environmental chamber to simulate conditions during Hurricane Katrina. Paired measurements vs control were obtained using 3 aqueous reagent levels for GMS1 and 2 for GMS2.Results: Stress affected the performance of GMS1 at level 1 (P <. 01); and GMS2 at both levels (P <. 001), lowering GMS1 results but elevating GMS2 results. Glucose median-paired differences were elevated at both levels on GMS2 after 72 hours. Median-paired differences (stress minus control) were as much as −10 mg/dL (range, −65 to 33) at level 3 with GMS1, with errors as large as 21.9%. Glucose median-paired differences were as high as 5 mg/dL (range, −1 to 10) for level 1 on GMS2, with absolute errors up to 24.4%.Conclusions: The duration of dynamic stress affected the performance of both GMS1 and GMS2 glucose test strips. Therefore, proper monitoring, handling, and storage of point-of-care (POC) reagents are needed to ensure their integrity and quality of actionable results, thereby minimizing treatment errors in emergency and disaster settings.(Disaster Med Public Health Preparedness. 2012;6:232–240)
Rapid Disaster Victim Identification in Mass Fatality Incidents: Decision-Support Tool to Facilitate Human Remains Identification
Authors: de Cosmo Sergio , Barbera Joseph A. 
Published: October 2012

ABSTRACTObjectives:A quantitative decision-support tool (DST), using a combination of selected human physical attributes as identification elements, was developed to facilitate body identification in mass fatality incidents, particularly in settings with limited availability of technological resources and forensic expertise.Methods:To construct the DST, the external biological attributes of interest were first selected. A process was then developed to guide collection of the selected categories of attributes and record them into objective antemortem (AM) and postmortem (PM) records. Finally, a framework for assessing the similarity between confronting PM-AM attribute records was established. The DST evaluates the similarities between each set of like attributes in the AM and PM records being compared. It then computes an overall similarity score for each evaluated AM record that was compared to a selected PM record. The AM record with the highest score represents the highest probable match, with the PM file selected for the comparison.Results:Multiple simulations across a range of mass fatality situations demonstrated the effectiveness of the DST in the experimental setting.Conclusions:The developed DST may provide authorities with a method for expediting body identification without completely eliminating any missing person file from consideration. Under specific circumstances, this method may reduce the need for technologically sophisticated forensic identification techniques (eg, dental records, fingerprints, and DNA). At a minimum, it should facilitate the efficiency of the current technological matching process.(Disaster Med Public Health Preparedness. 2012;6:277–290)

ABSTRACTOn March 11, 2011, a magnitude 9.0 earthquake and subsequent tsunami damaged nuclear reactors at the Fukushima Daiichi complex in Japan, resulting in radionuclide release. In response, US officials augmented existing radiological screening at its ports of entry (POEs) to detect and decontaminate travelers contaminated with radioactive materials. During March 12 to 16, radiation screening protocols detected 3 travelers from Japan with external radioactive material contamination at 2 air POEs. Beginning March 23, federal officials collaborated with state and local public health and radiation control authorities to enhance screening and decontamination protocols at POEs. Approximately 543 000 (99%) travelers arriving directly from Japan at 25 US airports were screened for radiation contamination from March 17 to April 30, and no traveler was detected with contamination sufficient to require a large-scale public health response. The response highlighted synergistic collaboration across government levels and leveraged screening methods already in place at POEs, leading to rapid protocol implementation. Policy development, planning, training, and exercising response protocols and the establishment of federal authority to compel decontamination of travelers are needed for future radiological responses. Comparison of resource-intensive screening costs with the public health yield should guide policy decisions, given the historically low frequency of contaminated travelers arriving during radiological disasters.(Disaster Med Public Health Preparedness. 2012;6:291–296)

Understanding the Mechanism of Solvent‐Mediated Adhesion of Vacuum Deposited Au and Pt Thin Films onto PMMA Substrates

Published: October 2012

AbstractThe adhesion of vapor deposited Au and Pt thin films onto poly(methyl methacrylate) (PMMA) substrates can be significantly enhanced by either spin‐casting or vapor‐exposure to hydrohalocarbon solvents prior to metal deposition. X‐ray photoelectron spectroscopy (XPS) and evolved gas analysis Fourier transform infrared spectroscopy detect residual halogenated solvent at the PMMA surface which chemically activates the surface. Density functional theory (DFT) calculations show that the solvent molecules form a Lewis acid‐base adduct with the ester oxygens in PMMA. DFT predicts that the deposited metal atom (M) inserts into the C–halogen (X) bond on either CHCl3 or CHBr3 to form a O–M–X interaction. This is consistent with M–X bonding observed in high resolution XPS. A model is proposed in which the bond energy of the C–X bond of the solvent must be weak enough so that it can be cleaved by the metal atom to form a M–X bond. A negative control of PMMA exposed to CHF3 is shown to have no effect on Au or Pt adhesion since the bond dissociation energy of the C–F bond is stronger than the C–Cl and C–Br bond energy compared to the metal halide bond energies.

Published: October 2012

AbstractA series of aryl‐substituted naphthalenediimide derivatives that contain nitroxide radicals were prepared and their crystal structures were elucidated. Much stronger charge‐transfer interactions were present in the derivatives with perfluorobenzene substituents than those with phenyl or 4‐fluorophenyl substituents. These interactions result in the formation of single‐component charge‐transfer complexes by self‐assembly of the naphthalenediimide derivatives to provide black crystals. As a consequence, the naphthalenediimide derivatives with perfluorobenzene substituents have better field‐effect transistor (FET) properties than the other derivatives.

AbstractRecent years have witnessed growing applications of the molecular imprinting technique for the detection of pesticide residues in environmental and food samples. In this study, molecularly imprinted polymers (MIPs) for pyrethroids, a class of popular insecticides, were synthesized by the crosslinking of β‐cyclodextrin (β‐CD) with 1,6‐hexamethylene diisocyanate (HMDI) or toluene‐2,4‐diisocyanate (TDI) in dimethyl sulfoxide, with lambda‐cyhalothrin (LCT) as a model template. Equilibrium batch‐rebinding tests were operated in different aqueous solutions. The results indicate that MIP prepared with TDI (MIP–TDI) possessed a much greater binding activity to LCT than MIP based on HMDI (MIP–HMDI), and MIP–TDI displayed a remarkably specific binding to LCT (with an imprinting factor of around 3) in an acetonitrile/water (4:7 v/v) mixture. The adsorption of LCT by MIP–TDI reached equilibrium after 3 h; this demonstrated comparatively rapid adsorption kinetics. Also, MIP–TDI could be regenerated eight times at least; this implied that the robust β‐CD polymer has the potential for practical applications. Furthermore, a cross‐selectivity study indicated that the high adsorption of LCT and its analogues by MIP–TDI in aqueous media must have been ascribed to the cooperative effects of CD inclusion interaction and stereoshape memory. This study paved the way for the use of β‐CD as a functional monomer for preparing smart artificial receptors for the efficient recognition of pyrethroids under aqueous conditions. © 2012 Wiley Periodicals, Inc.

Published: October 2012

AbstractAn epoxy–anhydride formulation used for the coating electrical devices was modified with a commercially available hyperbranched poly(ester amide), Hybrane S2200, to improve the thermal degradability of the resulting thermoset and, thus, facilitate the recovery of substrate materials after the service life of the component. The thermomechanical, mechanical, and dielectric properties and thermal degradability were studied and interpreted in terms of the composition and network structure of the cured thermosets. Although the crosslinking density was significantly reduced with the incorporation of S2200, the glass transition temperature of the fully cured material (Tg∞) of the modified thermoset was hardly affected because of the enhancement of H‐bonding interactions in the presence of S2200. Despite the different network structures, the combined dielectric and dynamic mechanical analysis revealed that the relaxation dynamics of both networks were very similar. In terms of application, improvements in the dielectric and mechanical properties were observed. The incorporation of S2200 accelerated the thermal decomposition of the material and, thus, facilitated the recovery of the valuable parts from the substrate at the end of the service life of the apparatus. © 2012 Wiley Periodicals, Inc.

Comparison of direct solvents for regenerated cellulosic fibers via the lyocell process and by means of ionic liquids
Authors: Ingildeev D. , Effenberger F. , Bredereck K. , Hermanutz F. 
Published: October 2012

AbstractBecause new technology using ionic liquids (ILs) for cellulose processing enables the spinning of cellulose with various techniques, the resulting fiber property profiles differ significantly, depending on the process parameters. ILs are thermally stable, nontoxic, environmentally friendly solvents and dissolve cellulose directly; this leads to a high flexibility in the complete process chain for man‐made cellulosics. A comparison of the manufacture of cellulosic fibers according to the Lyocell process and by means of ILs is presented. The rheological behavior of the spinning dopes, the structures, and the physical textile properties of the prepared fibers were determined. The fibers spun from solutions of cellulose in N‐methyl morpholin‐N‐oxide monohydrate, 1‐ethyl‐3‐methyl imidazolium acetate, and 1‐ethyl‐3‐methyl imidazolium diethyl phosphate were compared. © 2012 Wiley Periodicals, Inc.

Wettability alteration of gas condensate reservoir rocks to gas wetness by sol–gel process using fluoroalkylsilane
Authors: Sharifzadeh S. , Hassanajili Sh. , Rahimpour M. R. 
Published: October 2012

AbstractNatural gas is becoming a very important energy source in recent years. A sharp reduction has been observed in gas deliverability in many low permeability gas reservoirs due to bottom‐hole pressure drops below the dew point pressure. It is an established fact that altering the wettability of reservoir rocks from liquid wetness to gas wetness could improve the gas deliverability. In this study, a new polymeric surfactant coating for altering the wettability of Sarkhun reservoir rocks was prepared by using a sol–gel process. Perfluorodecylsilane (PFDS) and triethoxysilane (TEOS) were used to obtain an inorganic‐organic network via hydrolysis and polycondensation reactions. The effect of this method was examined by various characterization tests such as FTIR, SEM, and EDX, static contact angle and imbibition tests for wettability alteration. The experimental results revealed that, the prepared polymeric network including the terminal fluorine groups were effective and provided sufficient repelling characteristics towards oil and water. Static contact angles were raised from 30 to 130° for water, and from <5 to 60° for condensate after sol–gel treatment. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: October 2012

AbstractA deep study on the possibility to increase the quality of the dispersion of organically modified Boehmite nanoparticles into photo‐polymerizable methacrylic‐siloxane monomers, to be used as coatings, was conducted using unconventional indirect analyses. The nanocomposite were produced using two different procedures, starting from the conventional “solvent dispersion method.” The two procedures used differ for the technique used to obtain the dispersion of Boehmite, i.e., sonication or magnetic stirring and for the time used in each procedure. The efficiency of each method of preparation of nanostructured systems was analyzed, both in the liquid (uncured) and ultraviolet (UV) cured state. First, dynamic light scattering and rheological measurements were performed on the liquid suspensions, supplying experimental data used in proper theoretical models to estimate the dimensions and distribution of Boehmite particles. The suspensions obtained with the two different methods were, then, UV cured obtaining thin and thick films, on which scanning electron microscopy and transmittance measurements were performed. © 2012 Wiley Periodicals, Inc.

Design and Synthesis of Aza‐Flavones as a New Class of Xanthine Oxidase Inhibitors
Authors: Dhiman Rajni , Sharma Sahil , Singh Gagandip , Nepali Kunal , Singh Bedi Preet Mohinder 
Published: October 2012

AbstractIn an attempt to develop non‐purine‐based xanthine oxidase (XO) inhibitors, keeping in view the complications reported with the use of purine‐based XO inhibitors, the flavone framework (a class possessing XO inhibitory potential) was used as lead structure for further optimization. By means of structure‐based classical bioisosterism, quinolone was used as an isoster for chromone (a bicyclic unit present in flavones), owing to the bioactive potential and drug‐like properties of quinolones. This type of replacement does not alter the shape and structural features required for XO inhibition, and also provides some additional interaction sites, without the loss of hydrogen bonding and hydrophobic and arene–arene interactions. In the present study, a series of 2‐aryl/heteroaryl‐4‐quinolones (aza analogs of flavones) was rationally designed, synthesized and evaluated for in vitro XO inhibitory activity. Some notions about structure–activity relationships are presented indicating the influence of the nature of the 2‐aryl ring on the inhibitory activity. Important interactions of the most active compound 3l (IC50 = 6.24 µM) with the amino acid residues of the active site of XO were figured out by molecular modeling.
On the Two‐Inertia System: Analysis of the Asymptotic Behaviors to Multiple Feedback Position Control
Authors: Hu Jia‐Sheng , Hu Feng‐Rung , Kang Chung‐Hao 
Published: October 2012

AbstractThis paper presents a new analysis to explain the asymptotic behavior of the two‐inertia system on multiple feedback schemes with mechanism backlash. A linear pole placement controller for two‐inertia system position control is designed and is utilized for performance evaluation. Unlike the describing function approximation in nonlinear control, this paper presents an alternative analysis for evaluating system performance. This approach evaluates the asymptotic behaviors within semi/full/dual‐closed loop position controls that involve the effect of mechanism backlash in mechanical systems. The crucial lemmas to examine the compensation policies are formulated by theoretical discussion. The results provided by numerical simulation demonstrate the correctness and effectiveness of the analysis.
Predictive Direct Torque Control of Matrix Converter Fed Permanent Magnet Synchronous Machines
Authors: Ortega Carlos , Arias Antoni , Espina Jordi 
Published: October 2012

AbstractThis work presents a predictive direct torque control method for matrix converters fed permanent magnet synchronous machine drives. A new look‐up table for direct torque control using matrix converters has been developed. The new look‐up table delivers a set of three different vectors, every sample period, that fulfil the torque and flux demands. Based on a predictive algorithm, the voltage vector from the matrix converter ensuring the minimum torque ripple is selected. The system predicts the torque error for each of the three voltage vectors and selects the one that contributes with the minimum error. Simulation and experimental results, which confirm the good performance of the proposed predictive direct torque control using matrix converters are shown.

AbstractBACKGROUND: Nonsyndromic cleft lip with or without cleft palate (NSCL/P) is one of the most common of all congenital anomalies, and has a multifactorial etiology involving both environmental and genetic factors. Recent genome‐wide association studies (GWAS) identified strong association between a locus on chromosome 10q25.3 and NSCL/P in European samples. One gene at 10q25.3, the ventral anterior homeobox 1 (VAX1) gene, is considered a strong candidate gene for craniofacial malformations. The purpose of the present study was to provide further evidence that VAX1 is the causal gene at the 10q25.3 locus through identification of an excess of rare mutations in patients with NSCL/P. METHODS: The 5′UTR, complete coding regions, and adjacent splice sites of the two known VAX1 isoforms were sequenced in 384 patients with NSCL/P and 384 controls of Central European descent. Observed variants were investigated with respect to familial cosegregation or de novo occurrence, and in silico analyses were performed to identify putative effects on the transcript or protein level. RESULTS: Eighteen single‐base variants were found, 15 of them rare and previously unreported. In the long VAX1 isoform, predicted functionally relevant variants were observed more often in NSCL/P cases, although this difference was not significant (p = 0.17). Analysis of family members demonstrated incomplete cosegregation in most pedigrees. CONCLUSION: Our data do not support the hypothesis that highly penetrant rare variants in VAX1 are a cause of NSCL/P. To determine whether VAX1 is the causative gene at 10q25.3 further research, in particular into the biologic function of its long isoform, is warranted.

Micellar‐mediated binding interaction between proflavine hemisulfate and salicylic acid: Spectroscopic insights and its analytical application
Authors: Patil Dhanshri T. , Mokashi Vidya V. , Kolekar Govind B. , Patil Shivajirao R. 
Published: October 2012

ABSTRACTThe molecular interactions between salicylic acid (SA) and proflavin hemisulfate (PF) were investigated using fluorescence and UV–VIS absorption spectroscopy in an aqueous micellar environment. Changes in the absorption spectra of SA in the presence of PF indicate a ground state interaction between salicylate and proflavine hemisulfate ions to form a complex. The excitation bands of SA monitored at its emission wavelength reveal a red spectral shift of 8390.54 and 2037.75 cm‐1 when compared with absorption bands. The intensity of both excitation bands decreased in the presence of increasing amounts of PF. The absence of excitation bands of PF rules out the possibility of its direct excitation and suggests energy transfer from excited SA to PF, resulting in quenching of the SA fluorescence. The fluorescence quenching results were found to fit the well‐known Stern–Volmer (S–V) relation. S–V plots at different temperatures were used to further evaluate thermodynamic parameters such as ∆G, ∆H and ΔS. The thermodynamic and kinetic data obtained from the quenching results were used to investigate the possible mechanism of binding, the nature of the binding force and the distance between SA and PF molecules. The linear relation between SA fluorescence quenching and PF concentration used to develop an analytical method for the determination of PF from Lorexane (a veterinary cream) using a fluorescence quenching method.
