Human exposure to fumonisins from home grown maize in Tanzania
Authors: Kimanya M. , De Meulenaer B. , Tiisekwa B. , Ndomondo-Sigonda M. , Kolsteren P.
Published: September 2008

Fumonisins contaminate maize worldwide resulting in unacceptable fumonisin exposures in people relying on maize as staple food. This study determined fumonisins B1 (FB1) and B2 (FB2) in maize from 120 rural households: 30 from each of four main maize producing regions of Tabora, Ruvuma, Iringa and Kilimanjaro in Tanzania in order to estimate total fumonisin (FB1 + FB2) exposures to adult individuals in the households. The average daily per capita maize consumption of 771 g, recommended by the Tanzania Food and Nutrition Centre (TFNC) for an adult relying on it as a main meal, and also average daily per capita maize consumptions of 129, 308 and 356 g documented for Tanzania, were used in the exposure estimation. The fumonisins were determined by HPLC using fluorescence detection. Total fumonisins exposure (µg/kg body weight (bw)/day) was determined by multiplying average daily per capita maize consumption (kg) by fumonisin level in maize (µg/kg) from a given household and then dividing by an average bw of an adult of 60 kg. Of the 120 samples, 52% were contaminated with fumonisins at levels of up to 11,048 µg/kg (median; 363 µg/kg). Based on the recommended maize consumption of 771 g/person/day, fumonisin exposures to adult individuals in 38% of the households would exceed the provisional maximum tolerable daily intake (PMTDI) of 2 µg/kg bw, recommended by the Joint FAO/WHO Expert Committee on Food Additives. At the least documented maize consumption of 129 g/person/day, fumonisin exposures in 16% of the households were still above the PMTDI. Reduction of the maize consumption level to 40 g/person/day is an impractical, and reduction of the maximum contamination level to 155 µg/kg is a possibly practical, option for effective minimisation of fumonisin exposures in these communities. A relatively larger study is needed in order to generate comprehensive data for the formulation of appropriate strategies to minimise fumonisin exposures in Tanzania.
Catalysis of Intramolecular Morita–Baylis–Hillman and Rauhut–Currier Reactions by Fluorous Phosphines; Facile Recovery by Liquid/Solid Organic/Fluorous Biphase Protocols Involving Precipitation, Teflon® Tape, and Gore‐Rastex® Fiber
Authors: Seidel Florian O. , Gladysz John A.
Published: September 2008

The fluorous phosphine P[(CH2)3Rf8]3 [1, Rf8=(CF2)7CF3; 10 mol%] catalyzes intramolecular Morita–Baylis–Hillman reactions of O=CH(CH2)nCHCH(CO)R [n/R=2/Ph (2a), 2/S‐i‐Pr, 3/p‐tol] in acetonitrile at 60–72 °C. Upon cooling, 1 precipitates and is recycled. The products HOCH(CH2)nCHC(CO)R are isolated from the supernatant (78–96%). The educt i‐PrS(CO)CHCH(CH2)2CHCH(CO)S‐i‐Pr similarly undergoes a Rauhut–Currier reaction to give i‐PrS(CO)CH2CH(CH2)2CHC(CO)S‐i‐Pr (71–73%). In the case of 2a, reactions are also conducted in the presence of Teflon® tape or Gore‐Rastex® fiber. The catalyst now precipitates onto the fluoropolymer support, mechanically facilitating recycling. For each reaction, three to five cycles are conducted. HPLC or GC monitoring of the rates show low activity losses, with Gore‐Rastex® fiber giving better results than Teflon® tape, presumably due to a higher surface area.

Authors: Zhang Liang , Wu Jie
Published: September 2008

The combination of rhodium(I) and N‐hetercyclic carbenes (NHC) was found to be effective as a catalyst for cross‐coupling reactions of aryl arenesulfonates with arylboronic acids, which gave rise to the desired biaryl compounds in good yields.
The measurement and importance of red cell survival
Authors: Franco Robert S.
Published: September 2008

The measurement of red blood cell survival in the circulation has progressed from the original differential agglutination technique of Ashby to current isotopic and flow cytometric methods. While occasionally useful in the clinic, these methods find widespread use in a number of important research areas, including the evaluation of new red cell storage media in transfusion medicine and studies of the pathophysiology of sickle cell disease and diabetes. In this review, measurement techniques are placed in historical perspective and examined for relative merits and suitable application. Am. J. Hematol., 2009. © 2008 Wiley‐Liss, Inc.

Echtzeit‐Röntgenuntersuchungen an duktilen stabförmigen Holzverbindungen bei dynamischer Beanspruchung
Authors: Wehsener Jörg , Kasal Bo
Published: September 2008

Der Beitrag beschreibt die Möglichkeiten von Röntgenuntersuchungen an stabförmigen Holzverbindungsmitteln im beanspruchten Bauteil. Trotz verschiedenartiger Untersuchungsmethoden ist die Bestimmung des tatsächlichen Verhaltens von metallischen Verbindungsmitteln im Holz während der Belastung nicht ausreichend gelöst. Mit Hilfe verschiedener mathematischer Ansätze und der Einbeziehung von Materialkennwerten ist die Modellierung von Holzverbindungen möglich. Die Nutzung von Röntgenstrahlen unter Echtzeitwiedergabe ermöglicht es, das Verformungsverhalten von metallischen Verbindungsmitteln während der Lasteinleitung zu beobachten.

Ziel der Versuche war die Bestimmung des Verformungsverhaltens einer Stabdübelverbindung in Echtzeit unter quasistatischer und dynamischer Belastung. Mit der Echtzeit‐radio‐graphischen Messung wurden Versuche am Einzelstabdübel und einer Dübelgruppe durchgeführt. Die beim Versuch genutzte Anlage besteht aus einer mobilen Röntgenröhre und einem Detektor, sowie der dazugehörigen digitalen Bildverarbeitung. Bei maximaler Geschwindigkeit von 30 Bildern in der Sekunde wird eine Grenzwertauflösung von 1,97 lp/mm erreicht. Die Pixelteilung ist mit 127 μm2 durch das Empfängermodul vorgegeben [10]. In Abhängigkeit der gewählten Parameter konnte die Verschiebung um einen Bildpunkt (0,21 mm) verifiziert werden. Eine Überprüfung der gemessenen Verformungen der Stabdübel erfolgte mit Hilfe von direkt aufgebrachten Dehnmessstreifen.
Pyramidenbau im Alten Ägypten über Rampen und mit Seilwinden
Authors: Müller‐Römer Frank
Published: September 2008

In der Vergangenheit wurden von Ägyptologen und Archäologen, Ingenieuren und interessierten Laien verschiedenste Hypothesen zum Bau der Pyramiden im Alten Ägypten vorgelegt. Dennoch wurde für die Fragen, nach welchem Verfahren, in welchen Abschnitten, mit welchen Hilfsmitteln und innerhalb welcher Zeit die Pyramiden erbaut wurden, noch kein in sich geschlossener und widerspruchsfreier Lösungsvorschlag zur Diskussion gestellt.

Ausgehend vom Stand der ägyptologischen Forschung und den archäologischen Befunden, wurden vom Autor bisher bekannt gewordene Hypothesen zum Bau und Bauvorschläge nach wissenschaftlichen Methoden analysiert und daraufhin überprüft, inwieweit die Pyramiden im Alten Ägypten danach hätten errichtet werden können. Darauf aufbauend wird eine neue, aus den archäologischen Befunden des AR abgeleitete und in sich widerspruchsfreie Hypothese für den Bau der Stufenpyramiden im Alten Reich entwickelt. Diese verbindet erstmals den Einsatz steiler, parallel zu den Stufen des inneren Kernmauerwerks angeordneter Rampen in Kombination mit der Walze in Form der Seilwinde für den Materialtransport und den Bau einer äußeren Arbeitsplattform für die gefahrlose Montage des Pyramidion und die Glättung der Pyramidenverkleidung von oben nach unten. Die danach berechneten Bauzeiten stimmen mit den belegten Regierungsjahren von drei Königen (Snofru, Cheops und Mykerinos) überein.

Published: September 2008

Glycosyltransferases (GTs) are crucial enzymes in the biosynthesis and diversification of therapeutically important natural products, and the majority of them belong to the GT‐B superfamily, which is composed of separate N‐ and C‐domains that are responsible for the recognition of the sugar acceptor and donor, respectively. In an effort to expand the substrate specificity of GT, a chimeric library with different crossover points was constructed between the N‐terminal fragments of kanamycin GT (kanF) and the C‐terminal fragments of vancomycin GT (gtfE) genes by incremental truncation method. A plate‐based pH color assay was newly developed for the selection of functional domain‐swapped GTs, and a mutant (HMT31) with a crossover point (N‐kanF‐669 bp and 753 bp‐gtfE‐C) for domain swapping was screened. The most active mutant HMT31 (50 kDa) efficiently catalyzed 2‐DOS (aglycone substrate for KanF) glucosylation using dTDP‐glucose (glycone substrate for GtfE) with kcat/Km of 162.8 ± 0.1 mM−1 min−1. Moreover, HMT31 showed improved substrate specificity toward seven more NDP‐sugars. This study presents a domain swapping method as a potential means to glycorandomization toward various syntheses of 2‐DOS‐based aminoglycoside derivatives. Biotechnol.

Determination of acyclovir in horse plasma and body fluids by high‐performance liquid chromatography combined with fluorescence detection and heated electrospray ionization tandem mass spectrometry
Authors: Maes A. , Garré B. , Desmet N. , van der Meulen K. , Nauwynck H. , De Backer P. , Croubels S.
Published: September 2008

Two methods are presented for the determination of ‘respectively’ the plasma protein unbound and total concentration of acyclovir in horse plasma and body fluids: first, a liquid–liquid extraction was performed on plasma, combined with HPLC‐fluorescence detection for the total plasma concentration; second a more sensitive method using high‐performance liquid chromatography combined with heated electrospray ionization tandem mass spectrometry (LC‐HESI‐MS/MS) was described for plasma and for body fluids analysis. To obtain the unbound concentration of acyclovir in plasma, a simple deproteinization step using a Microcon® filter was performed. Ganciclovir was used as an internal standard. Analysis was carried out on an Inertsil 5 ODS‐3 column for the HPLC‐fluorescence method. For the LC‐HESI‐MS/MS method a PLRP‐S column was used. The limit of quantification (LOQ) for the total concentration was set at 50 and 2 ng mL−1 for the HPLC‐fluorescence method and the LC‐HESI‐MS/MS method, respectively. The limit of quantification for the unbound concentration was set at 5 ng mL−1 and at 2 ng mL−1 for body fluids. The methods were successfully used to perform pharmacokinetic and clinical studies in horses after intravenous and oral dosage of acyclovir and its prodrug valacyclovir.

Authors: Shi Songxin , Zhang Guojun , Shao Xinyu
Published: September 2008

The integration with virtual reality is a new boost to CAD and CAE. This paper presents a research effort aimed at creating a desktop‐based, low‐cost and independent VR‐based simulation system for glass pressing, which integrates the forming process simulation and mold motion simulation. The skeletal animation technique is employed for motion simulation of the mold. The stereoscopic view of the virtual system is achieved by CrystalEyes shutter glasses, with C++ language and OpenGL support library selected as the development tool. With the stereoscopic display of the mold design, pressing motion and numerical CAE results, the system enables engineers to gain a cohesive view of mold structure, assembly issues, and possible forming faults. It can also support training of students and engineers to acquire the theoretical know‐how, practical skills, and the problem troubleshooting techniques of glass pressing. © 2008 Wiley Periodicals, Inc.

Design of Gold Nanoparticle‐Based Colorimetric Biosensing Assays
Authors: Zhao Weian , Brook Michael A. , Li Yingfu
Published: September 2008

Gold nanoparticle (AuNP)‐based colorimetric biosensing assays have recently attracted considerable attention in diagnostic applications due to their simplicity and versatility. This Minireview summarizes recent advances in this field and attempts to provide general guidance on how to design such assays. The key to the AuNP‐based colorimetric sensing platform is the control of colloidal AuNP dispersion and aggregation stages by using biological processes (or analytes) of interest. The ability to balance interparticle attractive and repulsive forces, which determine whether AuNPs are stabilized or aggregated and, consequently, the color of the solution, is central in the design of such systems. AuNP aggregation in these assays can be induced by an “interparticle‐crosslinking” mechanism in which the enthalpic benefits of interparticle bonding formation overcome interparticle repulsive forces. Alternatively, AuNP aggregation can be guided by the controlled loss of colloidal stability in a “noncrosslinking‐aggregation” mechanism. In this case, as a consequence of changes in surface properties, the van der Waals attractive forces overcome interparticle repulsive forces. Using representative examples we illustrate the general strategies that are commonly used to control AuNP aggregation and dispersion in AuNP‐based colorimetric assays. Understanding the factors that play important roles in such systems will not only provide guidance in designing AuNP‐based colorimetric assays, but also facilitate research that exploits these principles in such areas as nanoassembly, biosciences and colloid and polymer sciences.
Surfactant Effects on Aeration Performance of Stirred Tank Reactors
Authors: Martinov M. , Gancel F. , Jacques P. , Nikov I. , Vlaev S.
Published: September 2008

The effect of surfactants on aeration performance in stirred tank reactors (STR) at high rates of foaming is studied. The volumetric oxygen transfer coefficient (kLa) and foaming activity estimated as foaming height (Hf) were determined. Biotechnology of lipopeptide biosurfactants from aerobic organisms, e.g., Bacillus subtilis were addressed. Using model solutions of known foam‐generating properties, high‐molecular weight surfactin and low‐molecular weight sodium dodecyl sulphate (SDS), as well as impellers of different types, with flat and fluid‐foil blades, clues on the concentration dependence of STR oxygen transfer and foaming as well as options for foam reduction in the presence of biosurfactant were sought. In response to a two‐fold decrease of surface tension by surfactin, kLa values decreased up to 30 % but remained within the range expected for the mixing system in water; the experiments with SDS showing stronger dependence on surfactant concentration and surface tension. Mixing of surfactant media by a standard six‐blade disc turbine (RT) imposed rate limitations on gassing. A low‐shear impeller Narcissus (NS) could be used to avoid bulk foam outflow, while preserving kLa values that remained unchanged. The ‘power per unit volume' correlation of kLa in stirred tanks is tested in the presence of surfactin.
Gas‐Liquid Mass Transfer in a Bench‐Scale Trickle Bed Reactor used for Benzene Hydrogenation
Authors: Metaxas K. , Papayannakos N.
Published: September 2008

The gas‐liquid mass transfer coefficients (MTCs) of a trickle bed reactor used for the study of benzene hydrogenation were investigated. The Ni/Al2O3 catalyst bed was diluted with a coarse‐grained inert carborundum (SiC) particle catalyst. Gas‐liquid mass transfer coefficients were estimated by using a heterogeneous model for reactor simulation, incorporating reaction kinetics, vapor‐liquid equilibrium, and catalyst particle internal mass transfer apart from gas‐liquid interface mass transfer. The effects of liquid axial dispersion and the catalyst wetting efficiency are shown to be negligible. Partial external mass transfer coefficients are correlated with gas superficial velocity, and comparison between them and those obtained from experiments conducted on a bed diluted with fine particles is also presented. On both sides of the gas‐liquid interface the hydrogen mass transfer coefficient is higher than the corresponding benzene one and both increase significantly with gas velocity. The gas‐side mass transfer limitations appear to be higher in the case of dilution with fine particles. On the liquid side, the mass transfer resistances are higher in the case of dilution with coarse inerts for gas velocities up to 3 · 10–2 cm/sec, while for higher gas velocities this was inversed and higher mass transfer limitations were obtained for the beds diluted with fine inerts.
A Comparison of Variational and Genetic Algorithm Performances in the Optimization of a Polymerization Process
Authors: Banu I. , Bozga G. , Nagy I. , Puaux J.‐P.
Published: September 2008

The aim of this work is to compare the performances of two well‐known methods, Minimum Principle and Genetic Algorithm, in the optimization of the methyl methacrylate polymerization process in solution. In order to select a kinetic model for this process, the published kinetic models were reviewed and compared by simulation in similar operating conditions. Based on the kinetic model proposed by Baillagou and Soong (1985), the temperature profile necessary to attain, in a given reaction time, specified values for monomer conversion, number‐average molecular weight and polydispersity index, was calculated. The temperature profiles calculated by the two optimization algorithms are practically identical, but they are obtained with different computational efforts. The results of this comparison are used to draw several conclusions regarding the proficiency of the two methods in the optimization of complex reaction processes.
Stochastic Modeling of the Particle Residence Time Distribution in an Opposed Multi‐Burner Gasifier
Authors: Ni J. J. , Liang Q. F. , Guo Q. H. , Yu Z. H. , Yu G. S.
Published: September 2008

The gasification technology of impinging streams has been extensively applied to chemical production and power generation. Particle residence time distribution (RTD) is an important parameter required for modeling, designing and optimization of an impinging stream gasifier. A stochastic mathematical model based on the Markov chains model is developed for the opposed multi‐burner gasifier (OMBG), which closely describes the behavior of the flow pattern and particle RTD in the gasification system. The model simulates the motion of single particle moving in the gasifier using the Markov chains. The predicted results give a reasonable fit to the experimental data. This shows that the flow process of particles in the gasifier has recirculation eddies, which have a downward flow direction near the downflow core and an upward flow direction near the wall, but no short‐circuit. Finally, the effect of particle flux rate on the RTD is predicted, and the contrast between gas and particles RTDs at a laboratory scale and in an industrial gasifier are presented.
Mathematical Modeling of Supercritical Extraction of Valerenic Acid from Valeriana officinalis L.
Authors: Salimi A. , Fatemi S. , Zakizadeh Nei Nei H. , Safaralie A.
Published: September 2008

The dynamic behavior of supercritical fluid extraction (SFE) of valerenic acid (VA) from valerian (Valeriana officinalis L.) roots was studied by mathematical modeling. The extraction yield of VA was considered as the most desirable compound among the other extracted constituents. A two‐phase desorption model was developed by considering a diffusion controlled regime in the particle and axial dispersion in the bed. The mass transfer parameters, i.e., pore diffusivity, film mass transfer coefficient and axial dispersion, along with the solubility parameters were chosen as the model parameters. The first three mass transfer parameters were predicted using nondimensional equations from the literature. The solubility equation and the parameters were studied using different equilibrium models, i.e., Henry, Langmuir, Freundlich, Langmuir‐Freundlich (L‐F) and Toth isotherms. The equilibrium parameters were correlated by comparing the outlet results of the dynamic SFE model with experiments. The experimental yield of the VA extraction was obtained at a pressure of 15.0–36.0 MPa, temperature of 310–334 K, solvent flow rate of 0.50–1.10 · 10–6 m3/min and different particle sizes ranging from 0.18–2.00 · 10–3 m in diameter, at a 20 min constant static period, in the presence of 46.9 μL/g ethanol as the co‐solvent, followed by dynamic time extraction for up to 50 min. From the results, the mathematical model using the L‐F equation exhibited the best agreement with the experimental yield of VA extraction in the range of studied conditions. The present model can be applied to design and scale up the SFE process of VA from Valeriana officinalis L. roots.
Portraying the Countercurrent Flow on Packings by Three‐Dimensional Computational Fluid Dynamics Simulations
Authors: Xu Y. Y. , Paschke S. , Repke J.‐U. , Yuan J. Q. , Wozny G.
Published: September 2008

The design of packed columns requires the detailed description of the hydrodynamics on the surface of the packings. To analyze the local flow behavior of the liquid phase, a three‐dimensional Computational Fluid Dynamics (CFD) model was developed that applies to the two‐phase countercurrent flow on an inclined and flat plate. This model, based on the volume‐of‐fluid (VOF) method, considers the gravity, the surface tension and the drag force between the two phases. The development of such a model allows investigation of the influences of the liquid and gas flow rates on the flow behavior such as the film flow and the rivulet flow. A validation of the model was performed using data from the literature and from experiments conducted in this work. Simulation and experimental results demonstrate that the specific wetted area on the plate decreases with decreasing liquid load. Moreover, CFD simulations reveal that the presence of the countercurrent gas phase tends to increase the fluctuation and the thickness of the film flow, which is in accordance with experimental data. It also affects the flow behavior of the rivulet flow and changes the velocity profiles for both film and rivulet flow behavior. On the other hand, the simulation results indicate that CFD is a potent tool for analyzing and investigating the flow phenomena in chemical engineering.
Two New Thermodynamic Constraints for a Solid/Supercritical Fluid System
Authors: Esmaeilzadeh F. , Bozorgi Y.
Published: September 2008

One of the phenomenological observations in any supercritical system is the common pressure where all the solubility isotherms intersect. Thus, this crossover pressure addresses a thermodynamic constraint or a key set of conditions for supercritical mixtures. In this paper, a phase stability analysis has been performed for the formulation and estimation of the crossover pressure. This absolute theoretical approach includes two subsequent steps. At the first step, it has been formulated in terms of an abstract quantity, i.e., Gibbs free energy. However, the system should be treated more quantitatively in order to estimate the crossover pressure. Therefore, at the second step, which is based on the solute behavior at the infinite dilution limit, the equations formerly used have been further manipulated, which ultimately leads to two equations that are given in terms of estimable properties. They are actually two thermodynamic constraints for solid/SCF mixtures. One of them has been used to predict the crossover pressure of certain mixtures. The other one has not been used for this task due to a theoretical restriction. However, the successfully prediction of the crossover pressure by using either of the equations confirms the other one since they are subsequent and related equations.
Anion‐Responsive Supramolecular Gels
Authors: Maeda Hiromitsu
Published: September 2008

Supramolecular gels that change their state or structure in response to anion stimuli have been highlighted. Only a few examples exist of such supramolecular gels, the structures and properties of which can be controlled and modulated by interactions with anions. To form anion‐responsive dimensionally‐controlled organized structures, the constituent low‐molecular‐weight gelator molecules must act as anion receptors by possessing one or more of van der Waals interaction units (aliphatic chains), stacking π planes, hydrogen‐bonding sites, and metal‐coordination units. This Concept focuses on the gelation and transition behaviors of amide‐ and urea‐based anion‐stimulated systems, metal‐coordinated systems, and novel acyclic π‐conjugated oligopyrroles that act as “molecular flippers.”
