Natural gas storages in salt caverns are receiving an increasingly important role in energy storage system of many countries. This study focuses on analyzing the consequence of jet fire associated with natural gas storages in salt caverns. A widely used software, ALOHA, was adopted as simulation tool. The reliability of ALOHA was validated by comparing the simulated results with the field data observed in real accidents and the values calculated by a simple model presented in a previous study. The China's first natural gas storage in salt cavern, Jintan natural gas storage, was selected for case study. The case study reveals that the hazard distance of jet fire decreased with the increase of pipeline length, as well as the decrease of pipeline diameter and operating pressure.

The outer space of city, construction space and underground space are city’s material spaces with disaster prevention function and are direct carriers of disasters, this paper propsoses the concepts and approaches to integrate, recombine and share city spaces based on the current situation of city’s disasters and spaces for disaster prevention, puts forward ideas and concepts including “ active disaster prevention”, “comprehensive disaster prevention”, “evacuation center” combining the latest research development of nanjing city’s comprehensive disaster prevention planning, and conducts deeper research in aspects of improving the disaster prevention function of city space and inspring planning and construction of city disaster prevention.

Currently, more and more residential district have built the underground parking and created more water and green space use the ground. The environment has been improved. This paper analyzed the microclimate of two planning programs use the microclimate fluid dynamics simulation software Envi-met, that one is have been made the underground parking planning, the other one is haven't. The results include microclimate parameters air quality parameters (the distribution of CO2) and the outdoor thermal comfort parameters (mean radiant temperature). By comparing the results of the two programs, this paper quantitative analyzed the influence and benefits of the underground parking to the microclimate in residential quarter.

This paper deals with the study of smart substation system level test. The test include three parts:network performance test,electronic transformer test and conformance testing.Network performance test involves the process layer network and station level networks test, transmission delay and frame loss rate of switch is tested.Electronic transformer test contains accuracy test, absolute delay test and polarity test. Conformance test is a test for model based on IEC 61850,test flow is studied.

A novel nonpeptide angiotensin II receptor 1 antagonist, compound 1, N-butyryl-N-[(2'-(2, 5-dihydro-5-oxo-1, 2, 4-oxadiazol-3-yl) biphenyl-4-yl) methy-L-Valine was investigated by receptor-binding studies and vivo experiments in spontaneously hypertensive rats and renal hypertensive rats. Furthermore, treatment with compound 1 significantly inhibited the viability of human breast cancer cell line and promoted apoptosis of the cancer cells. The compound had the effects of anti-hypertension and anti-cancer, which suggested that this new compound could be considered as a candidate for both novel anti-hypertensive and anti-cancer agent.

Pyropheophorbid-a (PyroPheo) is one of the well-known photosensitizers which can be useful for future clinical applications. This work is aimed to compare and measure generation rates of single oxygen through activation of pyropheophorbide-a by four different wavelength, and observe the sensitivity of pyropheophorbide-a mediated photodynamic therapy for eca-109 cell. Methods: UV-vis spectrophotometrics was used to measure decrease of singlet oxygen probe 9,10-dimethylanthracene(DPBF) so as to evaluate singlet oxygen production generation. The Eca-109 cells were were exposed to light (650nm) with a constant light power of 200mW/cm2, at a distance of 5cm, for 25 to 200 seconds. The results were measured by MTT assay. Results: pyropheophorbide-a in DMF solution irradiation by different light power can produce singlet oxygen quickly. Comparison of single oxygen generation rate has proved that photodynamic effect at 532nm is fastest, followed by 650nm, 635nm, 690nm which has correlation with absorbance of pyropheophorbide-a. The survival rate of cells dropped after irradiation by light what was significantly different from other groups. Conclusion: pyropheophorbide-a is an excellent photosensitizer and prooxidant. Through activated by different wavelength it could be apply to different disease

As the development of the economic of China and the acceleration of urbanization, metropolises have run out of land resources. Therefore, developing and utilizing the underground space becomes the inevitable trend of sustainable urban development. The modern urban space is a three-dimensional space system which is made up of above and below parts of the space. According to the city on or under the ground, the different characteristics exist. Arranging their own appropriate functions, and avoid weaknesses, will not only make best use of their function, but also promote each to form a good system of urban functions to ensure the city’s efficient and orderly operation.
