In this work, the nickel-aluminum layered double hydroxide （Ni-Al LDH） with nitrate interlayer anion was synthesized and used as a solid phase extraction sorbent for the selective separation and pre-concentration of mefenamic acid prior to quantification by UV detection at λmax ？ 286 nm. Extraction procedure is based on the adsorption of mefenamate anions on the Ni-Al（NO3？） LDH and/or their exchange with LDH interlayer NO3？ anions. The effects of several parameters such as cations and interlayer anions type in LDH structure, pH, sample flow rate, elution conditions, amount of nano-sorbent and co-existing ions on the extraction were investigated and optimized. Under the optimum conditions, the calibration graph was linear within the range of 2-1000 mg/L with a correlation coefficient of 0.9995. The limit of detection and relative standard deviation were 0.6 mg/L and 0.84% （30 mg/L, n ？ 6）, respectively. The presented method was successfully applied to determine of mefenamic acid in human serum and pharmaceutical wastewater samples.

In [1], Hamzeh, Iranmanesh and hossein-zadeh and M. V. Diudea recently introduced the generalized degree distance of graphs. In this paper, we present explicit formulas for this new graph invariant of the Cartesian product, composition, join, disjunction and symmetric difference of graphs and introduce generalized and modified generalized degree distance polynomials of graphs, such that their first derivatives at x = 1 are respectively, equal to the generalized degree distance and the modified generalized degree distance. These polynomials are related to Wiener-type invariant polynomial of graphs.

The main aim of the research is survey of relationship between personality characteristics with academic staffs’ job satisfaction and mental health in the University of Guilan. The statistic population was all these academic staffs in the year of 2014 (500). 196 individuals have selected by Kerjecy & Morgan (1970) and random sampling method. The research instruments were personality characteristics (NEO), General Health Questionnaire (GHQ) and self-made questionnaires. Pearson’s Correlation, Multiple Regression and Multiple Variant (Manova) have used for analyzing data. Results showed that there was a relationship among neurotic and settlement’s personality characteristics with job satisfaction and neurotic, openness, extroversion personality characteristics and settlement with mental health. Some of personality characteristics had been anticipators of mental health and job satisfaction and personality characteristics with mental health and job satisfaction had differenced depend on sociologic variances relationships.

Periodic Nanostructured anti-reflection coatings (NALs) are a promising option for enhancing transmission of coherent light without inducing scattering. We’ve found that reducing the height of NALs below a critical value to enhance mechanical stability can highly reduce the transmission efficiency. Here, using Rigorous Couples Wave Analysis (RCWA), we find the minimum height for over 99% transmission and effect of height on transmission bandwidth. Then, during a one-step plasma etching, two samples with different heights have been generated and their efficiency is evaluated using RCWA.

＜正＞ This paper presents a novel approach to speech recognition using fuzzy modeling which is specifically designed to ignore noise. The task begins with conversion of speech spectrogram into a linguistic fuzzy description based on arbitrary colors and lengths. While phonemes are also described using these fuzzy measures, and recognition is done by a normal fuzzy reasoning, a genetic algorithm optimizes phoneme definitions so that to classify samples into correct phonemes. The method is tested over a standard speech data base and the results are compared with a widely used speech recognition approach.

Nanostructured, sub-wavelength anti-reflection layers (NALs) have attracted much attention as a new generation of anti-reflection surfaces. Among different designs, sub-wavelength periodic nanostructures are capable of enhancing transmission of coherent light through an interface without inducing scattering. In this work, we have explored a new profile for periodic NALs capable of transmitting IR light with higher efficiency compared to NALs based on a parabolic profile. To achieve high transmission and low diffraction, the profile and pitch of the nanostructured NALs are calculated using a combination of a multi-layer modeling and Rigorous Coupled Wave (RCWA) analysis.
