A rapid and sensitive lateral flow immunoassay (LFIA) based on competitive format was developed and validated for simultaneous detection of cyromazine (CA) and melamine (MA) in foods of animal origin. With this method, the cut-off value for the two test lines were achieved at 25 ng/g, which was lower than the maximum residue levels (MRLs) established for CA and MA. At three fortified levels (50, 100, and 150 ng/g), the recoveries for CA and MA ranged from 73.9% to 104.2% with the relative standard deviation (RSD) less than 11.9%, based on within day and interday analysis. The lower detection limit for CA and MA in matrix sample were 0.22 ng/ml and 0.26 ng/ml, respectively, which were lower than those of published literatures. A parallel analysis of CA and MA in real samples conducted by HPLC showed comparable results to those obtained from LFIA. The results of LFIA were in good agreement with those of high performance liquid chromatography (HPLC) in the analysis of CA and MA in foods of animal origin, demonstrating the practical applicability of the developed assay in real samples. Overall, to our knowledge, this is the first report of quantitative or semi-quantitative simultaneous detection for CA and MA by immunochromatographic assay. © 2012 Elsevier Ltd. All rights reserved.

With the arrival of information age, the accountant of the university educates and pays great attention to merging with informationalized infiltration, increase content of courses and range of information course in varying degrees, this has relieved the demand to the information talents of finance and economics of the society to a certain extent play a positive role. But with informationalized popularization and deepening, the higher accountant educates and exposes a great deal of questions, influence the realization of the professional train objective seriously, set up the in charge offing experiment platform, can promote informationization and combination which the higher accountant educated. © 2013 Springer-Verlag.

Gait recognition refers to automatic identification of individual based on his/her style of walking. This paper proposes a gait recognition method based on Continuous Hidden Markov Model with Mixture of Gaussians(G-CHMM). First, we initialize a Gaussian mix model for training image sequence with K-means algorithm, then train the HMM parameters using a Baum-Welch algorithm. These gait feature sequences can be trained and obtain a Continuous HMM for every person, therefore, the 7 key frames and the obtained HMM can represent each person's gait sequence. Finally, the recognition is achieved by Front algorithm. The experiments made on CASIA gait databases obtain comparatively high correction identification ratio and comparatively strong robustness for variety of bodily angle. Source

PKI is a new security technology, its role is to provide information security services, can use it to ensure that the network information security. This article describes the theoretical basis of PKI and related technologies and concepts, analysis and comparison of PKI-based trust model: hierarchical trust model, peer trust model, network trust model, hybrid trust model. Analyzes the current PKI trust management and related lack of trust management system, given the open network environment, trust management system should have features. © 2011 IEEE. Source

The mechanization of rice transplanting technology (referred to as the machine transplanting rice), is another major renovation after cultivation technique in rice production. Compared with manual transplanting rice, machine transplanting rice has the advantages of high work efficiency, low labor intensity, high yield potential. This paper explains the main problems existing in the promotion of rice and mechanization of rice transplanting technology, puts forward measures and suggestions of technology promotion, and analyzes the mechanization of rice transplanting high-yield cultivation techniques. © (2013) Trans Tech Publications, Switzerland.
