There may be not direct path from the psychological selection by the customers to the green behavior owing to the complexity of the green consumption. The specific mode of action still needs being further researched. This paper will research the specific path and mechanism of customer’s green consumption based on VBN theory. Based on a survey of Chinese respondents, environment values bring indirect influence to green customer behavior through individual belief or subjective norm intermediately. However, there are different paths from value to behavior. One path is that egoistic value-subjective norm-green customer behavior while another path is that altruistic value-environment beliefs-subjective norm-green customer behavior which really fits into previous research of VBN theory.

We propose a comprehensive modeling approach to investigate the rigid-flexible coupling vibration of a Ball-screw-drive spindle system (BSDSS). Taking into account the rigid-flexible coupling between the ball screw and rigid components, a hybrid dynamic model for the BSDSS is established. The ball screw shaft was modeled by a flexible beam with axial, torsional, and transverse deformations, and the Ritz series expansion was used to approximate the continuous deformations. The motion equations were obtained using the Lagrange method. The analytical solution was derived and verified. According to the proposed model, the dynamic behavior of the system for various operating conditions was simulated and discussed. The numerical simulation result is useful for the controller design or tuning and the stiffness matching design of ball screw drives.

Yb3þ/Tm3þ co-doped BaGd2ZnO5 phosphors have been effectively synthesized by traditional sol-gel method. The graph of X-ray diffraction (XRD) exhibited that the obtained phosphors were pure orthorhombic phase. The morphology and composition of the samples were obtained by field emissionscanning electron microscope (FE-SEM) and the energy dispersive spectrometry (EDS). From upconversion luminance (UCL) emission spectra, the two strong blue emissions were obviously observed at 478 and 485 nm under the excitation of 980 nm. The possible energy diagram and UC mechanism were explained in detail. Optical temperature (T) sensing performances were evaluated in the temperature ranging 313 K - 573 K. And the highest sensor sensitivity calculated was 0.0055 K『1 at 323 K. Additionally, the laser excitation heating effect was also explored. The results indicated that Yb3þ/Tm3þ codoped BaGd2ZnO5 phosphors could be applied on optical temperature sensors and optical heater.

Spent tire is a kind of solid waste with large production, accumulation and great pollution. Spent tire charis the primary product of tire harmless disposal. Its commercial value is enhanced by modification. In thisstudy, K-N co-doped activated carbon was prepared by using spent tire char as raw material, KOH andmelamine as activator and dopant to enhance CO2 capture. In comparison with traditional process, thereasons for the decrease in specific surface area and pore volume caused by K doped have been identified,and a potential doped mechanism has been proposed. It was determined that pyridine nitrogen in theamino functional group played a key role in CO2 adsorption. Meanwhile, the synergistic intensificationof CO2 adsorption by potassium phenolic and pyridine nitrogen was verified by simplified model simulation. The precise K-N doping significantly intensify the CO2 adsorption capacity of spent tire char from0.45 to 2.60 mmol/g (1 bar, 0℃), an increase of 4.78 times. Thermodynamic studies have demonstratedthat the Langmuir model accurately describes the adsorption process, and the adsorption reaction takesplace spontaneously at temperatures below 80.52 C. This work presents an efficient process for upgradingspent tire char, and a novel method of co-treating waste and CO2.

Hepatic injury is significant in the pathogenesis and development of many types of liver diseases. Punicalagin (PU) is a bioactive antioxidant polyphenol found in pomegranates. To explore its protective effect against carbon tetrachloride (CCl4)-induced liver injury and the mechanism, Institute of Cancer Research (ICR) mice and L02 cells were used to observe the changes of serum biochemical indicators, histopathological liver structure, cell viability, antioxidative indices, and autophagy-related proteins were assessed. In ICR mice, PU ameliorated the CCl4-induced increase of the serum aspartate aminotransferase, alanine aminotransferase, the activity of liver lactate dehydrogenase, and the damage of histopathological structure, and exhibited a hepatoprotective effect against CCl4. PU attenuated oxidative stress by decreasing the liver malondialdehyde level and increasing the activities of liver superoxide dismutase, glutathione peroxidase, and the expression of the liver nuclear factor E2-related factor (Nrf2) protein. Furthermore, according to the vivo and vitro experiments, PU might activate autophagy through the mediation of the Akt/FOXO3a and P62/Nrf2 signaling pathway. Taken together, these results suggest that PU may protect against CCl4-induced liver injury through the upregulation of antioxidative activities and autophagy.

As carbon fiber-reinforced plastics are widely used in aeronautical and aerospace industries, the improvement of their processing qualityis a crucial task. In recent years, helical milling, a brand new machining process that results in better hole quality with one-time machining,has been attracting increasing attention. Based on full factor experimental design, helical milling experiments were performed byusing a special cutter. Using the data obtained from the experiments, the correlation between the delamination and the process parameterswas established by developing an artificial neural network (ANN) model. MATLAB ANN Toolbox was used for modeling. The effectsof the process parameters on delamination at the exit of the machined holes were analyzed by using this model and the predicted results. The significance of the process parameters in the improvement of the hole quality in helical milling was also assessed.

Existing traffic generation methods generate traffic by the flow generator structured and then sent data packets, which had two problems, one is that the traffic generated is not enough authenticity, the other one is that the rate of flow is not high. For coping with the method for network traffic generation based on user behavior of streaming media and streaming media server was presented. The test results show that comparing with D-ITG, the size of traffic produced by this method has been obviously improved, and its principle indicates that the flow is highly authentic. The proposed method breaks through the traditional thinking of traffic generator sends packet by itself, which decreases the difficulty of the realization of the traffic generator and has good reference value for the researches and development of traffic generator.

Purpose: The purpose was to compare the accuracy of Miniaci method using picture archiving and communication system (PACS) with a cable method in high tibial osteotomy (HTO). Materials and Methods: This study analyzed 47 patients (52 knees) with varus deformity and medial osteoarthritis. From 2007 to 2013, patients underwent HTO using either a cable method (20 knees) or Miniaci method based on a PACS image (32 knees). In the cable method, the 62.5% point of the mediolateral tibial plateau width was located using an electrocautery cord under fluoroscopy (cable group). The Miniaci method used preoperative radiographs to shift the weight bearing axis (PACS group). Full-length lower limb radiographs obtained preoperatively and at the sixth postoperative week were used to compare the percentage of crossing point of the weight bearing line on the tibial plateau with respect to the medial border. Results: The weight bearing line on the tibial plateau was corrected from a preoperative 11.0±7.0% to a postoperative 47.2±7.4% in the cable group and from 12.7±4.9% to 59.5±5.3% in the PACS group. The mechanical femorotibial angle was corrected from varus 8.9±3.7° to valgus 0.3±4.0° in the cable group and from varus 9.0±3.3° to valgus 2.9±2.6° in the PACS group. Conclusions: In HTO, correction based on the Miniaci method using a PACS was more accurate than correction using the cable method.
