The preparation of corn starch phosphates which possess height thermal viscosity was optimized in this study. A central composite design of response surface methodology involving phosphate (sodium dihydrogen phosphate and disodium hydrogen phosphate) concentration, ratio of sodium dihydrogen phosphate and disodium hydrogen phosphate, phosphorylation temperature and urea concentration was used, and second-order model for thermal viscosity was employed to generate the response surface. The optimum condition for preparation of corn starch phosphates of high thermal viscosity was as follows: phosphate concentration 4.94%; ratio of sodium dihydrogen phosphate and disodium hydrogen 0.80, phosphorylation temperature 145°C; urea concentration 5.5%. The predicted value for thermal viscosity of corn starch phosphates at the optimum condition was 7652 cP. Experimental verification gave value of 7550±25 cP.

Based on the large deflection theory for the extensible elastic beams, the governing equations of post-buckling of a cantilever elastic beam subjected to a non-conservative distributed tangential follower force along the central axis were established. They consist of a boundary value problem of ordinary differential equations with strong non-linearity, in which seven unknown functions were included and the arc length of the deformed axis is considered as one on the basic unknown functions. By using shooting method and analytical continuation, the nonlinear boundary-value problem was numerically solved as well as the post-buckling configurations of the deformed beam were obtained. The results show that the features of the equilibrium paths of the cantilever beam subjected to a non-conservative load are evidently different from those to a conservative one.

The paper was to describe the intergenerational differences of mental health among migrant workers and how social support and personality influence their mental health. Discriminant sampling method was utilized to choose target floating population of 1097 people in Sunan area, Jiangsu province. The result was measured by Symptom Checklist 90, Eysenck Personality Questionnaire and Social Support Rating Scale . According to the result, the score of SCL-90, compulsion, interpersonal sensitivity, depression, anxiety, hostility, phobia, paranoid and schizophrenia in new generation of migrant worker is higher than the old generation . The score of neuroticism in new generation of migrant workers is higher than the old generation and the score of Lie is lower than the old generation. The total score of objective support, subjective support and social support for new generation of migrant workers is dramatically lower than the old generation. Regression analysis indicates that there is a correlation between neuroticism, extraversion, introversion and mental health for new generation of migrant workers whereas the neuroticism, extraversion, introversion and subjective support is correlated with the mental health for the old generation of migrant workers. In conclusion, the mental health status for new generation of migrant workers is lower than the old generation. The factor of neuroticism, extraversion and introversion dimensionality is related with mental health for the new generation of migrant workers.

Existing indoor navigation systems face with many different technical and usability problems. In this paper we present a Near Field Communication (NFC) based indoor navigation system called NFC Internal in order to eliminate the current indoor navigation problems. NFC Internal enables an easy data transfer for indoor navigation systems just by touching tags spread over a building or a complex. The proposed system has several benefits and has potential to increase the usability of these systems. We discuss the system requirements and explain the phases of NFC Internal through use cases.
