A ultra performance liquid chromatography coupled with quadrupole-time of flight mass spectrometry method for the determination of antibiotics drug residues in tilapia was developed using dispersed solid phase extraction as sample preparation method. The matrixmatched standard calibration method was used for quantitation. The results showed great reduction of the matrix effect with corrected matrix factor ranging 0.84~1.17 for 9 antibiotics. Within the linear range, the correlation coefficients(R2)of the calibration curves for the compounds were greater than 0.90. The average recoveries in blank tilapia ranged from 78.04%~103.08%, with intra-and inter-day relative standard deviation(RSD)ranged from 1.37%~9.86%and 3.86%~9.92%, respectively. The limit of detection(LOD)and limit of quantification(LOQ)of the method ranged from 0.31~16.37μg/kg and 1.04~54.56μg/kg, respectively. The method developed in the present study had the advantages of simple operation, less matrix interference, high recovery rate and good repeatability. So it could be used for the detection of multi-antibiotics in tilapia and provide some technical support for food safety supervision. [ABSTRACT FROM AUTHOR]

Aircrafts and typical ground objects have an important application value in military. In order to obtain training samples to study the detection, recognition and dynamic monitoring of the targets, we develop a new piece of software which can achieve infrared image simulation of typical aircrafts and ground objects in different conditions, including different seasons, different weather conditions, and different times of the day. Based on the Visual Studio 2010 environment, we build a model of aircrafts and typical ground objects on the OpenGL. Besides, we adopt the theoretical analysis of heat transfer and infrared radiation, and embed the kernel of the RadThermIR which is a heat-analysis tool, into the algorithm. Finally, we propose a simulation method to calculate the infrared radiation intensity and build up infrared images of aircrafts and typical ground objects. The similarity of image grey scale is taken as the evaluation index, and the test results reveal that the simulation accuracy of infrared images can reach over 80%, providing rich training samples for target auto-detection, target recognition and object tracking of the aircrafts on airport.

The management of environment, health, and safety (EHS) is of great importance to labs of universities. The frequently encountered problems in the construction and running of labs reveal the existing legal defects of our current laws and regulations related to EHS, such as lack of compulsory force and low compliance. These indicate the necessity of special legislation. Through reviewing and analyzing the experience of some foreign countries in management of EHS, it pointed out that EHS laws and regulations, as well as the management system established under these acts could serve as a guarantee for the secure and effective running of the labs. Adopting with the practical experience, it was feasible to propose special legislation on EHS for the labs of universities in China based on the superior legislation. [ABSTRACT FROM AUTHOR]

Objective To investigate the effect of Shang-tune music on the relief of negative emotions in patients with chronic obstructive pulmonary disease (COPD), and to analyze potential factors influencing the efficacy of the intervention. Methods A prospective research method was adopted, and totally 120 COPD patients were recruited in the study. All patients received the Shang-tune music intervention during hospital stay, and extended care with telephone was used to improve patients’ compliance with music therapy during follow-up, lasting for 12 weeks. The COPD Assessment Test(CAT) was used the assess the severity of illness. Hamilton Depression Scale(HAMD) and Hamilton Anxiety Scale(HAMA) were used to assess the emotional status of patents. A logistic regressive method was conducted to analyze the potential factors influencing the efficacy of the intervention. Results The HAMA and HAMA scores decreased after a 12-week intervention of Shang-tune music therapy(P＜0. 01). There was a significant difference in proportion of patients who diagnosed as anxious/depressive disorders before and after intervention (P＜0. 01). Logistic regression analysis showed that course of disease, extrovert personality, high education level, knowledgeable about music, family support and CAT score were factors influencing the intervention effect on relief of depression(P＜0. 05), and patients receiving Shang-tune music therapy had an odds ratio of 3. 325(95% CI: 0. 876-36. 158, P＜0. 01) for relief of depression. Logistic regression analysis showed that extrovert personality, knowledgeable about music, family support and CAT score were factors influencing the intervention effect on relief of anxiety(P＜0. 05), and patients receiving Shang-tune music therapy had an odds ratio of 2. 825(95% CI: 0. 853-32. 268, P＜0. 01) for relief of anxiety. Conclusion The Shang-tune music is effective to relieving the anxiety and depression of COPD patients. Personal characteristics, education level, knowledge about music, family support and CAT scores were potential factors influencing the implementation of Shang-tune music therapy.
