| 1 | Metals in sediment/pore water in Chaohu Lake:Distribution,trends and flux显示文摘Nine metals,Cd,Cu,Ni,Pb,As,Cr,Zn,Fe,and Mn in sediment and pore water from 57 sampling sites in Chaohu Lake(Anhui Province,China)were analyzed for spatial distribution,temporal trends and diffuse flux in 2010.Metals in the surface sediment were generally the highest in the western lake center and Nanfei-Dianbu River estuary,with another higher area of As,Fe,and Mn occurring in the Qiyang River estuary.Metal contamination assessment using the New York sediment screening criteria showed that the sediment was severely contaminated in 44% of the area with Mn,20% with Zn,16% with Fe,14% with As,and 6% with Cr and Ni.An increasing trend of toxic metals(Cd,Cu,Ni,Pb,As,Cr,Zn)and Mn with depth was shown in the western lake.Compared with metal content data from the sediment survey conducted in 1980s,the metal content of surface sediment in 2010 was 2.0 times that in the 1980s for Cr,Cu,Zn,and As in the western lake,and less than 1.5 times higher for most of the metals in the eastern lake.Among the metals,only Mn and As had a widespread positive diffuse flux from the pore water to overlying water across the whole lake.The estimated flux in the whole lake was on average 3.36mg/(m2·day)for Mn and 0.08mg/(m2·day)for As,which indicated a daily increase of 0.93μg/L for Mn and 0.02μg/L for As in surface water.The increasing concentration of metals in the sediment and the flux of metals from pore water to overlying water by diffusion and other physical processes should not be ignored for drinking-water sources. | Shengfang Wen Baoqing Shan Hong Zhang | 2012 | Journal of Environmental Sciences2012,24,12: | 11 |
| 2 | Pathologic analysis on hyperplasia of mammary gland with different syndromes based on infrared radiation temperature of acupoints显示文摘OBJECTIVE:To explore the pathologic characteristics of hyperplasia of the mammary gland(HMG) by observing differences in infrared radiation temperature of points of HMG in patients with different syndromes compared with healthy controls.METHODS:AFLIRSystems Therma CAM P30 infrared thermal camera was used to detect the infrared temperature of Shanzhong(CV 17),Qimen(LR 14),Zhongwan(CV 12),Qihai(CV 6),Guanyuan(CV 4),Taixi(KI 3),and Taichong(LR 3) in 113 patients with HMG.Of these patients,71 were placed in the Liver Qi stagnation group,34 were placed in the Dysfunction of conception and thoroughfare vessels group,and 8 were placed in the Phlegm and blood stasis in combination group.The infrared radiation temperature of each point in the patients was compared with that of healthy controls,and the differences in the infrared radiation temperatures of the points in the patients were analyzed.RESULTS:Overall,the bilateral corresponding point in both the controls and patients exhibited no significant difference in infrared radiation temperature.In all cases,the infrared radiation temperature of the points from proximal to distal tended to decrease.In a comparison of the patients and controls,the infrared radiation temperature of the trunk points Shanzhong(CV 17),Qimen(LR 14),Zhongwan(CV12),Qihai(CV6),and Guanyuan(CV 4) of the patients was higher than that of the controls,while the infrared radiation temperature of the lower extremity points Taixi(KI 3) and Taichong(LR 3) was lower than that of the controls.Of these points,Shanzhong(CV 17)(P=0.0368),Zhongwan(CV 12)(P=0.0028),Qihai(CV 6)(P=0.0085),and Guanyuan(CV4)(P=0.0018) showed significant differences.In a comparison of the corresponding point on the same side in the Liver Qi stagnation group and controls,the infrared radiation temperature of Shanzhong(CV17)(P=0.0089),right-side Qimen(LR 14)(P=0.0382),Zhongwan(CV 12)(P= 0.0000),Qihai(CV 6)(P=0.0011),and Guanyuan(CV 4)(P=0.0000) of the patients was significantly higher than that of the controls,while the differences in the infrared radiation temperature of the other points were not statistically significant(P= 0.0833-0.8397).In a comparison of the corresponding point on the same side in the Dysfunction of conception and thoroughfare vessels group and controls,the infrared radiation temperature of left-side Taichong(LR 3)(P=0.0048),right-side Taichong(LR 3)(P=0.0329),left-side Taixi(KI 3)(P= 0.0171),and right-side Taixi(KI 3)(t=0.544,P= 0.0165) of the patients was significantly lower than that of the controls,while the differences in the infrared radiation temperature of the other points were not statistically significant(P=0.3793-0.9197).In a comparison of the corresponding point on the same side in the Phlegm and blood stasis in combination group and controls,the infrared radiation temperature of Shanzhong(CV 17),Qimen(LR 14),Qihai(CV 6),Guanyuan(CV 4),Taixi(KI 3),Taichong(LR 3),and Zhongwan(CV 12) tended to increase,but without statistical significance(P=0.175-.759).CONCLUSION:The corresponding points of HMG patients with different syndromes are in different deficiency/excess states.Changes in the infrared radiation temperature of the trunk points Shanzhong(CV 17),Qimen(LR 14),Zhongwan(CV 12),Qihai(CV 6),and Guanyuan(CV 4) are closely related to the pathological characteristics of the Liver Qi stagnation syndrome of HMG patients,while changes in the infrared radiation temperature of the lower extremity points Taixi(KI 3) and Taichong(LR 3) are closely related to the pathological characteristics of the Dysfunction of conception and thoroughfare vessels syndrome of HMG patients.On the whole,HMG patients with Liver Qi stagnation syndrome are characterized by 'upper excess,' and those with Dysfunction of conception and thoroughfare vessels syndrome are characterized by'lowerdeficiency.' | Yafang Wang Xueyong Shen Jian Ying Juanjuan Zheng Shengfang Hu Ling Zhao Haiping Deng HaimengZhang | 2012 | Journal of Traditional Chinese Medicine2012,32,3: | 9 |
| 3 | Fabrication of Fuze Micro-electro-mechanical System Safety Device显示文摘Fuze micro-electro-mechanical system(MEMS) has become a popular subject in recent years.Studies have been done for the application of MEMS-based fuze safety and arm devices.The existing researches mainly focused on reducing the cost and volume of the fuze safety device.The reduction in volume allows more payload and,thus,makes small-caliber rounds more effective and the weapon system more affordable.At present,MEMS-based fuze safety devices are fabricated mainly by using deep reactive ion ething or LIGA technology,and the fabrication process research on the fuze MEMS safety device is in the exploring stage.In this paper,a new micro fabrication method of metal-based fuze MEMS safety device is presented based on ultra violet(UV)-LIGA technology.The method consists of SU-8 thick photoresist lithography process,micro electroforming process,no back plate growing process,and SU-8 photoresist sacrificial layer process.Three kinds of double-layer moveable metal devices have been fabricated on metal substrates directly with the method.Because UV-LIGA technology and no back plate growing technology are introduced,the production cycle is shortened and the cost is reduced.The smallest dimension of the devices is 40 μm,which meets the requirement of size.To evaluate the adhesion property between electroforming deposit layer and substrate qualitatively,the impact experiments have been done on the device samples.The experimental result shows that the samples are still in good condition and workable after undergoing impact pulses with 20 kg peak and 150 μs duration and completely met the requirement of strength.The presented fabrication method provides a new option for the development of MEMS fuze and is helpful for the fabrication of similar kinds of micro devices. | DU Liqun JIA Shengfang NIE Weirong WANG Qijia | 2011 | Chinese Journal of Mechanical Engineering2011,24,5: | 8 |

| 13 | A new quantile treatment effect model for studying smoking effect on birth weight during Mother's pregnancy显示文摘This paper proposes a new quantile regression model to characterize the heterogeneity for distributional effects of maternal smoking during pregnancy on infant birth weight across different the mother's age.By imposing a parametric restriction on the quantile functions of the potential outcome distributions conditional on the mother's age,we estimate the quantile treatment effects of maternal smoking during pregnancy on her baby's birth weight across different age groups of mothers.The results show strongly that the quantile effects of maternal smoking on low infant birth weight are negative and substantially heterogenous across different ages. | Shengfang Tang Zongwu Cai Ying Fang Ming Lin | 2021 | Journal of Management Science and Engineering2021,6,3: | 1 |
