In this paper,an integrated procedure is proposed to identify cracks in a portal framed structure made of functionally graded material(FGM)using stationary wavelet transform(SWT)and neural network(NN).Material properties of the structure vary along the thickness of beam elements by the power law of volumn *** are assumed to be open and are modeled by double massless springs with stiffness calculated from their *** dynamic stiffness method(DSM)is developed to calculate the mode shapes of a cracked frame structure based on shape functions obtained as a general solution of vibration in multiple cracked FGM Timoshenko *** SWT of mode shapes is examined for localization of potential cracks in the frame structure and utilized as the input data of NN for crack depth *** integrated procedure proposed is shown to be very effective for accurately assessing crack locations and depths in FGM structures,even with noisy measured mode shapes and a limited amount of measured data.

AIMTo investigate the benefits of the Seattle protocol in the diagnosis of Chinese individuals with Barrett’s *** enrolled were patients from one center with endoscopically-suspected esophageal metaplasia. These patients first received narrow-band imaging-targeted biopsy, and later, the Seattle protocol-guided biopsy, within a period from October 2012 to December 2014. Those cases without initial pathologic patterns of intestinal metaplasia （IM） and then appearance or loss of IM tissue were designated as Group A or B, respectively. Those with initial pathologic patterns ofIM, which then persisted or were lost were designated as Group C or D, *** number of cases for each group was as follows： A： 20, B： 78, C： 31 and D： 14. The distribution of the Prague criteria M levels of Group A was significantly higher than Group B （ P = 0.174）. Among these groups, Group C had the highest proportions of hiatus hernia （54.8%）, long segment Barrett’s esophagus （29%）, and also the highest Prague criteria M levels. The sensitivity of IM detection was 69.2% for the narrow-band imaging-targeted biopsy and 78.5% for the Lee SW et al . Seattle protocol for Barrett’s esophagusSeattle protocol-guided biopsy. The difference was not signifcant （P = 0.231）. The number of detectable dysplasias increased from one case via the NBI-target biopsy to five cases via the Seattle protocol-guided biopsy, including one case of *** Seattle protocol improved the IM detection in our subjects with higher Prague criteria M levels and disclosed more cases with dysplastic tissues.

This study is aiming at controlling the microstructure of plasma sprayed Al2O3-TiO2 composite coatings using freeze granulated powders. As sprayed and sintered Al2O3 + 3wt%TiO2 powders were air plasma sprayed with industry process parameters and compared with a commercial powder. The resulting coatings were investigated with respect to powder flowability, porosity and microstructure of the granules. The results showed that microstructure and melting fraction in the coatings could be tailored with the freeze granulation process and heat treatment conditions.

THE CHOLERA EPIDEMIC

中华医学杂志(英文版) 1932年第9期 931-934页

作者： WU lien-TEH General Cholera Bureau.Chairman

The first case of bacteriologically confirmed cholera in Shanghai this year was reported on April 26, when a laborer, age 40, was taken with the disease in Chapel, according to the first cholera bulletin of the season issued by Dr. Wu lien-teh, director of the National Quarantine Service. This patient was admitted to the Thibet Road Infectious Diseases Hospital, Shanghai where he responded to treatment and recovered in a short length of time. Two other cases, both in Chinese controlled areas of the city, were notified on April 29 and May 1. Both of these patients have recovered. Since these first cases there have been a series of unusually mild cases. New

The present paper presents a numerical analysis of the difference in comfort level inside a room of a residential building when roof top turbine ventilator is installed. This analysis simulates various comfort factors which includes the indoor air movement, room temperature, Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD). Various test cases of ventilator exhaust rate were examined. The results showed that general comfort satisfying international standards in building can be achieved. This study also presents a qualitative and quantitative study of indoor air temperature and overall indoor air flow pattern. A promising conclusion that can be drawn from this study is that wind driven ventilators can play an important role in the design of a cost effective and energy efficient ventilation system inside a building.

作者： WU lien-TEH Being a Lecture Delivered at the Centenary Celebrations of the Canton Hospital Canton November 2 1935

Twenty years ago almost to a day the Chinese Medical Association (or theNational Medical Association as it was then) met in conference in this greatcity and also took part in the celebrations of the opening of the Kung-yiHospital. At that time the Governor of Kwangtung Province was Chu Ching-lan. Once again, the Chinese Medical Association now consisting of theamalgamated National Medical and China Medical Associations meets as guestof the Canton community; only this is a greater occasion because we arenot only celebrating the Iooth anniversary of the foundation of the CantonHospital but also the opening of the fine new buildings which have replacedthe old Institution.

AIM: To investigate the effectiveness of 4 d' anti-Helicobacter pylori therapy on the H pylori-infected Mongolian gerbils based on physiological and pathological changes. METHODS: We used 6-wk-old male gerbils orally inoculated with H pylori (ATCC43504, 2×108 CFU/mL). Seven weeks after H pylori inoculation, the animals of study group received 4 d' anti-H pylori triple therapy (H pylori-eradicated group). Seven days later, all animals of the H pylori-eradicated and control groups (H pylori-infected & H pylori-uninfected groups) were sacrificed. We examined gastric mucosal lesions macroscopically, studied gastritis microscopically and determined the stomach weight ratio, myeloperoxidase (MPO) activity and prostaglandin (PG) E2 level. RESULTS: The results showed that both macroscopic and histological gastric damages were significantly less in H pylori-eradicated group than H pylori-infected group. Stomach weight ratio, MPO activity and PGE2 levels were significantly higher in H pylori-infected group than those in the other two groups. CONCLUSION: Four days' anti-H pylori therapy was effective in the improvement of H pylori-induced gastric lesions in Mongolian gerbils.
