Enzymatic Enantioselective Acylation of Sterically Aromatic Secondary Alcohol
Authors: Chua Lee‐Suan , Sarmidi Mohamad Roji 
Published: August 2010

AbstractThis study focused on the kinetic resolution of(R,S)‐1‐phenylethanol using lauric acid as acyl donor. The enantioselective esterification was catalysed by immobilised lipases in organic media. From exploratory experiments, several commercial immobilised lipases were screened for their efficiency in resolving the racemic alcohol. They were lipases from Pseudomonas cepacia, Candida antarctica and Candida rugosa (Candida cylindracea) with different immobilisation methods. The cross‐linked enzyme crystal of P. cepacia lipase (ChiroCLEC‐PC) and the carrier‐fixed lyophilised C. antarctica lipase B (Chirazyme L2, c.‐f., C3, lyo) showed the highest performance in term of enzyme activity as well as enzyme enantioselectivity. They were selective towards the R‐enantiomer of 1‐phenylethanol with enantiomeric ratio (E) above 200. The presence of S‐enantiomers in the racemic alcohol did not cause inhibition to the resolution. Kinetic studies were carried out by varying the substrates concentration at the determined reaction conditions. Both enzymes required three‐fold molar excess of lauric acid over (R,S)‐1–phenylethanol (50 mM) in order to achieve the highest initial reaction rate. When using the molar excess of (R,S)‐1–phenylethanol, equilibrium conversion dropped due to enzyme deactivation.
Decentralized Control for Multivariable Processes with Actuator Nonlinearities
Authors: Su S. W. , Bao J. , Lee P. L. 
Published: August 2010

AbstractDecentralized control is the most widely used control strategy in the process industries because of the simplicity to design and implement the controller, and the potential to achieve failure tolerant control. Actuator nonlinearities are often encountered in many chemical processes. This paper presents a decentralized control method for processes which have static actuator nonlinearities, such as saturation and dead zone. The proposed decentralized integral controller is designed based on feedforward passivation, which can be applied to nonminimum phase processes and/or processes of high relative degree. The concept of marginally stable positive real systems is used to analyse the stability of a closedloop system. The feedforward system is constructed to attain dynamic performance on the basis of frequency based passivity analysis. The effectiveness of the proposed approach is demonstrated using an example of a quadruple tank control problem.

Mathematical Modeling of the Vacuum Chamber of RH‐KTB Process
Authors: Huang Zong‐Ze , Chen Yi‐Sheng , He You‐Duo 
Published: August 2010

AbstractA mathematical model was developed for the simulation of gas flow, combustion and heat convection in the vacuum chamber of RH‐KTB process at Baosteel. Under different conditions, the model was used to predict the influence of the top oxygen blowing lance on the gas flow; chemical reactions and temperature distribution were calculated. The optimum position of the lance is suggested for the RH‐KTB process.
Hydrogel beads based on carboxymethyl cellulose for removal heavy metal ions
Authors: Yang Shaoping , Fu Shiyu , Liu Hao , Zhou Yiming , Li Xueyun 
Published: August 2010

AbstractEnvironment‐friendly carboxymethyl cellulose (CMC) hydrogel beads were successfully prepared using epichlorohydrin (ECH) as a crosslinking agent in the suspension of fluid wax. There was an ether linkage formed between ECH and CMC, which was identified from bands in FTIR spectra of the prepared hydrogel. The prepared hydrogel beads with diameters about 4 mm were apparently spherical and fully transparent. The X‐ray diffraction (XRD) spectra indicated that the adsorption of metal ion onto the oxygen atom of carboxyl group led to change in crystallinity patterns of hydrogels. The scanning electron microscope (SEM) images clearly showed that the hydrogels had an internal porous structure. The adsorption capacity increased as initial concentrations of metal ions and the pH value of metal ion solution increased. Freundlich and Langmuir isotherm models were employed to analyze the data from batch adsorption experiments. There are vey good correlation coefficients of linearized equations for Langmuir model, which indicated that the sorption isotherm of the hydrogel beads for metal ions can be fitted to the Langmuir model. The maximum adsorption amount of hydrogel beads for metal ions is 6.49, 4.06, and 5.15 mmol/g for Cu(II), Ni(II), and Pb(II), respectively. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Robust linear mixed models using the skewtdistribution with application to schizophrenia data
Authors: Ho Hsiu J. , Lin Tsung‐I. 
Published: August 2010

AbstractWe consider an extension of linear mixed models by assuming a multivariate skewtdistribution for the random effects and a multivariatetdistribution for the error terms. The proposed model provides flexibility in capturing the effects of skewness and heavy tails simultaneously among continuous longitudinal data. We present an efficient alternating expectation‐conditional maximization (AECM) algorithm for the computation of maximum likelihood estimates of parameters on the basis of two convenient hierarchical formulations. The techniques for the prediction of random effects and intermittent missing values under this model are also investigated. Our methodologies are illustrated through an application to schizophrenia data.
Die Rückkehr der Wölfe. Das erste Jahrzehnt
Authors: Ansorge Hermann , Holzapfel Maika , Kluth Gesa , Reinhardt Ilka , Wagner Carina 
Published: August 2010

AbstractSeit dem Jahr 2000 ziehen in Sachsen wieder Wölfe ihre Jungen auf. In ganz Deutschland leben derzeit mindestens 60 bis 80 Wölfe. Um den damit verbundenen Konflikten zu begegnen, wurde ein “Wolfsmanagement” entwickelt, das Wolfsmonitoring, Öffentlichkeitsarbeit und Schadensausgleich umfasst.Wissenschaftliche Untersuchungen zeigten, dass die Wölfe sich fast ausschließlich von wildlebenden Huftieren ernähren, Haus‐ und Nutztiere dagegen kaum eine Rolle spielen. Über genetische Analysen konnte die ursprüngliche Herkunft der nach Deutschland zugewanderten Wölfe aus Nordost‐Polen geklärt werden. Mit Hilfe der Radiotelemetrie wurden wichtige Erkenntnisse über die Anpassung der Wölfe in die vom Menschen veränderte Landschaft gewonnen.
