The performance of the sunflower oil in deep-fat frying was assessed by evaluating the efficacy of linoleic acid level and composition of tocopherol isomeric on its frying stability. The oil was used as a frying media to fry potato strips for 6 h daily for 7 days. Standard procedures for the measurement of used frying oil degradation such as fatty acid composition, acid value, anisidine value, conjugated diene value, total polar compounds and tocopherol concentration were used. At analogous composition of tocopherol isomers, the high oleic sunflower oil with smaller value of linoleic acid content indicated higher frying stability than the oil with higher linoleic acid level. This, indicating that the high oleic sunflower oil frying efficiency was depended mainly with the oil linoleic acid content and the composition of tocopherol isomers showed no significant effect. Also, the α-tocopherol degradation was lower compared to the corresponding degradation of γ-tocopherol. © 2017 Association of Food Scientists & Technologists (India)

The screen-printed gold electrode (SPGE) modified with the formation of self-assembly monolayer (SAM) of cysteine (Cys) on gold-nanoparticles (Au nano) was utilized for rapid and simultaneous determination of tetracycline and cefixime antibiotics by square wave voltammetry (SWV). Electrochemical investigation and characterization of the modified electrode was achieved using cyclic voltammetry (CV) and scanning electron microscopy (SEM). A principal component artificial neural network (PCANN) with three layer back-propagation network was utilized for the analysis of the voltammogram data. It is possible to simultaneously determine the tetracycline and cefixime concentrations in the ranges of 10-5 and 10-3 mol L -1, under the optimum conditions. Moreover the SPGE-Au nano-Cys biosensor together with chemometrics tools was successfully applied to the determination of tetracycline and cefixime in biological fluids, which may provide a promising alternative in routine biosensing applications. © 2013 Elsevier Ltd.

Hydrodynamic volume, radius of gyration, and viscometric constants, K and a, for dextran, with a wide molecular weight range were calculated using experimental reported average-molecular weights (M n, M w), and intrinsic viscosity, [η], data in water and 0.05 M Na 2SO 4. Degree of chain branching for dextran was also determined using different procedures. This study demonstrated that hydrodynamic volume and radius of gyration of a dextran sample with M w < 20 kDa and its linear counterpart with equal M w are almost identical, whereas the latter parameters for a dextran sample with M w > 20 kDa was smaller than that of its linear counterpart. Values of 0.506 in water and 0.512, 0.425 and 0.273 in 0.05 M Na 2SO 4 for the exponent a were obtained. A smaller value for a was obtained for a larger M w range. Molecular weights of desirable nano-particles for various branches of nanotechnology can be estimated from a derived radius of gyration-molecular weight relationship. © 2011 Elsevier Ltd All rights reserved.

The 71 constituents of essential oil (EO) of bay leaves were identified with gas chromatography-mass spectrometry (GC-MS) by applying a similarity search between the obtained mass spectra and database. This number was increased to 131 constituents with the help of different chemometric resolution techniques. Multivariate curve resolution-alternating least squares (MCR-ALS) is used to obtain pure chromatograms and mass spectra for the constituents present in each overlapping/embedded peaks cluster as well as their relative concentrations. Other chemometric methods such as simple to use interactive self-modeling mixture analysis (SIMPLISMA), morphological score (MS) and Fixed Size Moving Window Evolving Factor Analysis (FSMWEFA) were used to determine the number of constituents, pure variables, zero concentration and selective regions. The most important constituents of the Iranian bay leaves are linalool (12.31%), 1,8-cineole (11.38%), α-terpineol acetate (7.71%), eugenol methyl ether (6.87%) and α-phellandrene (4.30%). Despite previous studies, chemometric resolution techniques were implemented as a necessary step for the comprehensive analysis of the volatile constituents of bay leaves. © 2013 The Royal Society of Chemistry.

The fixed destination multi-depot multiple traveling salesmen problem (MmTSP) is a problem, in which more than one salesmen depart from several starting cities and having returned to the starting city, form tours so that each city is visited with exactly one salesman, and the tour lengths stay within certain limits. This problem is of a great complexity and few investigations have been done on it previously. In this paper an ant system is designed to solve the problem and the results are compared to the answers obtained by solving the same problems by Lingo 8.0 which uses exact methods. © 2010 Elsevier B.V.

Flexible manufacturing systems (FMS) consist of some multi functional machines that are linked together through material-handling system and the whole of the system control by a central computer. One of the most important problems in production planning of FMS is machine tool selection and operation allocation problem that directly influences the production costs and times. Here, a novel 0-1 linear integer programming model is presented in such a way that each part and each tool can move during the production phase. The objective of this model is to determine a machine-tool combination for each operation of the part type. The objective function calculates some production costs, such as machining costs, setup costs, material-handling costs, tool movement costs and maximum transformation times. This paper uses an elitist multi-objective evolutionary algorithm based on the non-dominated sorting genetic algorithm-II (NSGA-II), for solving the dynamic machine tool selection and operation allocation problem in FMS. Experimental results indicate effectiveness of the proposed algorithm for solving the problem. Copyright © 2013 Inderscience Enterprises Ltd.

Using cross-docking system is a new strategy to improve responding time to customers with transferring items directly from receiving trucks to shipping trucks without being held in storage at warehouse. This paper studies the scheduling of receiving and shipping trucks in cross-docking systems which have a temporary storage in front of shipping dock and items can be held temporarily in storage until the appropriate shipping truck comes. The objective is to find the best sequence of receiving and shipping trucks to minimize the total number of products that pass trough temporary storage because decreasing inventory or eliminating storage is the way to reduce costs. These kinds of problem are complex. Therefore, we develop an imperialistic competitive algorithm (ICA) approach to tackle complexity. The results of this algorithm are compared with the best known genetic algorithm (GA) results that are obtained in the same time. The results show that ICA outperformed GA. © 2010 Springer-Verlag London Limited.

There is an increasing need for the rapid safety assessment of chemicals by both industries and regulatory agencies throughout the world. In silico techniques are practical alternatives in the environmental hazard assessment. In this background, quantitative structure-toxicity relationship (QSTR) analysis has been performed on toxicity of phenols and thiophenols to Photobacterium phosphoreum. The techniques of classification and regression trees (CART) and least squares support vector regressions (LS-SVR) were applied successfully as variable selection and mapping tools, respectively. Four descriptors selected by the CART technique have been used as inputs of the LS-SVR for prediction of toxicities. The best model explains 91.8% leave-one-out predicted variance and 93.0% external predicted variance. The predictive performance of the CART-LS-SVR model was significantly better than the previous reported models based on CoMFA/CoMSIA and stepwise MLR techniques, suggesting that the present methodology may be useful to predict of toxicity, safety and risk assessment of chemicals. © 2012 Elsevier B.V.

Polyaniline (emeraldine)/anatase TiO2 nanocomposite (PA-NC) was prepared by a chemical oxidative polymerization. The thin films of PA-NC for hydrogen gas sensing application were deposited on Cu-interdigited electrodes by spin coating technique. A study on characteristics of PA-NC thin films was demonstrated by a porous cylindrical morphology. The response and response/recovery time of sensors for hydrogen gas were evaluated by the change of TiO2 wt% at environmental conditions. Resistance-sensing measurement was exhibited a high sensitivity about 1.63, a good Long-term response, low response time and recovery time about 83 s and 130 s, respectively, at 0.8 vol% hydrogen gas for PA-NC including 25% wt of anatase nanoparticles. The current-voltage characteristics of PA-NC gas sensors before and after hydrogen gas injection showed a nonlinear ohmic current. Moreover, we studied the formation of PA-NCs and their hydrogen gas sensing mechanism based on contact regions in PA-NC. Copyright © 2013, Hydrogen Energy Publications, LLC.

Plasma cholesteryl ester transfer protein (CETP) inhibitors are currently considered as potential drugs for treating high low-density lipoprotein cholesterol. In this work, we developed a receptor-based quantitative structure-activity relationship (QSAR) models based on a series of tetrahydronaphthyridines derivatives to support the design of new CETP inhibitors. Multivariate adaptive regression spline and adaptive neuro-fuzzy inference system were employed to select the best subset of descriptors and mapping tool. The obtained QSAR model indicates that the inhibitory activity can be described by relative negative charge, Moriguchi octanol-water partition coefficient, topological electronic indices, steric interaction, and hydrogen bonding energies between the receptor and the inhibitors. In addition, the docking analysis showed that the interaction of the inhibitors with residues of the ARG201 and ASP460 residues plays an important role in the activities of the inhibitors. The results of validation and applicability domain techniques show that the models exhibited optimum stability and good predictive power which can be used in prediction of activity of new CETP inhibitors. © 2013 Springer Science+Business Media New York.
