The 1995 Northern Niigata Earthquake (M 6.0) occurred at a shallow depth in the Niigata seismic gap. The anomaly areas in temperature, electrical conductivity and Cl- concentration of groundwater trend northeast as linear distribution in the epicentral area and are approximately coincident with the area of the seismic intensity 6 (JMA scale). The distributions of seismic intensity 6 and groundwater anomalies convincingly imaged the presence of a buried active fault beneath the epicentral area. The occurrence of this earthquake and the anomalies of groundwater were related to the expulsion of geopressured hydrothermal system (GHS). All epicenters of the destructive earthquakes along the Shinanogawa seismic belt are actually located in the buried active fault zones characterized by the areas of temperature and geochemical anomalies of groundwater. These earthquakes might have been triggered by the activity of GHS. The expulsion of GHS along an active fault in combination with the thermal softening of fault zone attributed to high rock temperature may reduce fracture strength of the rock, and trigger earthquake occurrence. The dimension of the anomaly area of groundwater temperature at the epicentral area reflected the scale of the earthquake fault. The linear anomaly areas of groundwater resulting from the expulsion of GHS and having no historical destructive earthquake are of the predicated areas of future destructive earthquakes. Monitoring of groundwater conditions in these areas may provide useful information regarding the future occurrence of earthquakes.

expulsion and primary migration of the oil derived from coal

引用

Science China Earth Sciences 1998年第4期41卷 345-353页

作者：赵长毅程克明 1. Research Institute of Petroleum Exploration and Development China National Petroleum Corporation 100083 Beijing China

The characteristics of coal pores and the interaction relationship between hydrocarbons and pores in coal are analysed based on the typical example of oil from coal in Tuha Basin, pointing out that the interaction between hydrocarbon molecules and coal pore surface particles is a major controlling factor of expulsion of oil from coal. Distribution characteristics of coal pores and the ability of hydrocarbon generation are inner factors of the expulsion of the oil from coal; tectonic compressive shear stress is an external force of the expulsion of oil from coal; expulsion of the oil from coal has greater geochromatographic effect than that from mudstone, the low mature stage (or vitrinite reflectance R\-o is less than 0.9%) is advantageous to the coal-formed oil expulsion and migration; hydrocarbons in the hydrocarbon network are linked with carrier beds (such as fault), through the pore network and fissure which are connected with each other, which constitutes the main pathway of expulsion and migration.

Influence of Surface Condition on expulsion in Spot Welding AZ31B Magnesium Alloy

引用

Journal of Materials Science & Technology 2005年第5期21卷 749-752页

作者： Yarong WANG, Jicai FENG and Zhongdian ZHANGState Key Laboratory of Advanced Welding Production Technology, Harbin Institute of Technology, Harbin 150001, China State Key Laboratory of Advanced Welding Production Technology Harbin Institute of Technology Harbin 150001 China

Experiments were carried out to study the influence of surface condition on expulsion during the spot welding of AZ31B Mg alloy. A general electrical contact resistance theory for conductive rough surfaces and the relation between maximum temperature Tm in the contact and voltage-drop V across interface of two surfaces were employed to understand the reason of expulsion in Mg alloy spot welding. The main reason of expulsion is that the high electrical contact resistance induced by large roughness of the surface and oxide film covered on the surface leads to local melting of metal in the interface of two surfaces, and liquid metal of the local area ejected from the specimen under electrode force forms expulsion.

作者： Issam Yazough Jean Marie Ovungu Pierlesky Elion Ossibi Franck Mvumbi Said AitLaalim Youssef Lamrani Imane Toughrai Karim Ibn Majdoub Khalid Mazaz Department of Visceral Surgery Hassan II University Hospital Fez Morocco Department of Radiology Hassan II Teaching Hospital Fez Morocco

Textiloma is a rare pathological entity which can possibly complicate any surgery. Its incidence, reported in literature, is estimated between 1/1000 and 1/15,000. Abdominal and gynecological surgeries are responsible for the vast of majority of intra abdominal textiloma. Very few cases of spontaneous rectal expulsion of textiloma have been reported. We report the case of rectal expulsion of textiloma in a 26-year-old female who had undergone a C section for dynamic dystocia a year prior to her admission.

Petroleum geological dynamics of Lower Paleozoic in the Ordos Basin, northwest China

引用

Science China Earth Sciences 2000年第4期43卷 401-411页

作者：叶加仁赵鹏大陆明德 Department of Petroleum China University of Geosciences Wuhan 430074 China

Taking the hydrocarbon source rocks of Ordovician, Lower Paleozoic in the Ordos Basin as the main research object, the characteristics of petroleum geological dynamics about geohistory, geothermal history, hydrocarbon generation history and hydrocarbon expulsion history were studied by using the methods of basin numerical modeling dynamically and pool-forming dynamics. It is shown that the Ordovician strata had entirely undergone five stages of initial deposition, uplift and erosion, rapid subsidence, alternating uplift and subsidence, and differential uplift and erosion; that under the background of lower heat flow on the whole, the paleoheat flow of Ordovician strata in the basin could be divided into two large stages of relatively high heat flow values period before Cretaceous deposition and relatively low ones after it; that the thermal evolution of organic matters in the hydrocarbon source rocks of Ordovician had entered into high mature-postmature stage on the whole and the intensity of gas generated was greater than that of oil generated, the hydrocarbon being mainly natural gas; and that the curves of the intensity of oil and gas expulsion at each time unit showed the feature of multi-peak-type, the accumulative intensity of gas expulsion was greater than that of oil expulsion. Thus natural gas exploration potential is good.

Postpartum intrauterine device contraception: A review

引用

World Journal of Obstetrics and Gynecology 2016年第1期5卷 134-139页

作者： Shadi Rezai Pameela Bisram Hasan Nezam Ray Mercado Cassandra E Henderson Department of Obstetrics and Gynecology Lincoln Medical and Mental Health Center St.George’s University School of Medicine Department of Obstetrics and Gynecology University of Toledo Medical Center

AIM： To review the safety （infection, perforation） and efficacy （expulsion, continuation rates, pregnancy） of intrauterine device （IUD） insertion in the postpartum period. METHODS： MEDLINE, PubMed and Google Scholar were searched for randomized controlled trials and prospective cohort studies of IUD insertions at different times during the postpartum period. Time of insertion during the postpartum period was documented speci-fically, immediate post placenta period （within 10 min）, early post placenta period （10 min to 72 h）, and de-layed/interval period （greater than 6 wk）. Other study variables included mode of delivery, vaginal vs cesarean, manual vs use of ring forceps to insert the IUD. RESULTS： IUD insertion in the immediate postpartum （within 10 min of placental delivery）, early postpartum （10 min up to 72 h） and Interval/Delayed （6 wk onward） were found to be safe and effcacious. expulsion rates were found to be highest in the immediate postpartum groups ranging from 14% to 27%. Immediate post placental insertion found to have expulsion rates that ranged from 3.6% to 16.2%. expulsion rate was significantly higher after insertion following vaginal vs cesarean delivery. The rates of infection, perforation and unplanned pregnancy following postpartum IUD insertion are low. Method of insertion such as with ring forceps, by hand, or another placement method unique to the type of IUD did not show any signifcant difference in expulsion rates. Uterine perforations are highest in the delayed/interval IUD insertion *** duration and infant development are not affected by delayed/interval insertion of the non-hormonal （copper） IUD or the Levonorgestrel IUD. Timing of the Levonorgestrel IUD insertion may affect breastfeeding. CONCLUSION： IUD insertion is safe and efficacious during the immediate postpartum, early postpartum and delayed postpartum periods. expulsion rates are highest after vaginal delivery and when inserted during the immediate post
