UV-Vis spectroscopy was used to directly determine the concentration of Eu（ Ⅱ） during electroreduction of Eu （ Ⅲ ） in hydrochloric acid medium. Electroreduction was carried out in a flow type electrolyzer with glassy carbon cathode at the constant potential of - 800 mV vs. Ag/AgCl. The effects of oxygen and concentration of hydrochloric acid on the system were investigated. For 0.01 mol· L^-1 hydrochloric acid, calibration curves for Eu （Ⅱ） absorption bands at 248 and 320 nm were constructed. Molar absorption coefficients were estimated to be 2016 and 648 L· mol^-1·cm^-1, respectively. The absorbance strongly decreased with decrease in pH of the solution, whereas concentration of chloride had only a negligible effect.

Ce （Ⅳ） nitrato complexes were adsorbed on two anion exchangers based on polyvinyl pyridine （PVP） and quatemized PVP incorporated into porous silica matrix. The effect of nitric acid concentration （0.5～6 mol·L^-1） and temperature （278 ～318 K） on Ce（ Ⅳ ） sorption efficiency was investigated. Sorption increased with increasing nitric acid concentration, indicating that [Ce（NO3）6]^2- complex is the main adsorbed Ce（Ⅳ） species. Oxidation of sorbents by adsorbed Ce （ Ⅳ ） species resulting in Ce （ Ⅲ ） release to the solution was observed. Pyridine based anion exchangers exhibited higher oxidation stability compared to the commercial strong base anion exchanger. Ce（ Ⅳ ） reduction was temperature dependent and obeyed pseudo-first-order reaction kinetics. Column separation of Ce （ Ⅳ ） from La （ Ⅲ ） and Y （ Ⅲ ） was carried out from 6 mol·L^-1 nitric acid with PVP based anion exchanger. Reasonable Ce （Ⅳ） breakthrough capacity （0.7 mol·kg^-1 PVP） was achieved. No remarkable decrease of capacity was observed within 3 consequent runs. In contrast, Ce （Ⅲ） leakage due to reduction decreased and breakthrough capacity slightly increased. This effect was more pronounced with increasing temperature. Regeneration with 0.1 mol·L^- 1 nitric acid was successful （recovery 100% ± 4% ） and Ce solution of high purity （〉 99.97% ） with respect to La and Y content was gained.

Electro-oxidation of Ce （ Ⅲ ） to Ce （ Ⅳ ） in parallel plate flow type electrolyzer divided with cation exchange membrane was carried out in nitric acid media at carbon felt anode under galvanostatic conditions. Carbon felt was used as an anode for its high specific surface area and high oxygen evolution overpotential. Pt coated Ti plates were used as cathode and anode current feeder. The oxidation of 1 mol· L^-1 Ce（ Ⅲ ） solution in 2 mol· L^- 1 HNO3 was proceeding with a high current efficiency （92%） until about 80% of Ce（ Ⅲ ） was oxidized. Then, oxygen evolution, accompanied by terminal voltage jump, took place, lowering current efficiency. Ce（ Ⅲ ） was oxidized up to 90% with current efficiency of 62%. In this mode, strong carbon felt anode oxidation was observed. The wear out of carbon felt was 46% in six consequent runs （6 h of operation）. After each run, carbon felt surface had to be renewed with slightly alkaline solution to remove carbon oxidation products and ensure regular operational conditions. When anode surface was blocked, oxygen evolution took place from the beginning of electrolysis due to higher actual current density. The wear out of carbon felt anode could be minimized by means of oxygen evolution prevention. In the case when electrolysis had been stopped before oxygen evolution started （at Ce（ Ⅳ ） conversion of about 80% ）, the wear out of anode was less than 2% during 6 consequent runs （4 h of operation）.

Objective: To determine whether endovaginal ultrasound is a reliable measure in visualization of the sacrospinous ligament among women with prolapse versus women without prolapse, and thus might be clinically applicable in the design of an ultrasound-guided device for performing sacrospinous ligament anchor placement as a treatment for pelvic organ prolapse. Methods: In the first phase of this study we performed a sacrospinous anchor placement in four normal fresh-frozen female pelves. Afterwards, an endovaginal ultrasound was performed to visualize the anchor localization which was validated by dissection of the cadaveric pelves. In the second phase of the study: two groups of volunteer females with and without pelvic organ prolapsed (POP-group, vs NON-POP group) were evaluated by endovaginal ultrasound to localize the sacrospinous ligament. Results: Cadaveric dissection demonstrated accurate anchor placement into the 8/8 sacrospinous ligament. We performed endovaginal ultrasound in a total of 17 N-POP and 10 (POP) patients. Among the N-POP group, the right and left ischial spines were visible in 6/17 (35%) and (6/17) 35% vs 0/10 (0%) for both right and left sides in POP group (p = 0.008). The right sacrospinous ligament was visualized in 4/17 (23%) N-POP subjects and 0/10 POP subjects (p = 0.27) and the left sacrospinous ligament was visualized in 7/17 (41%) N-POP subjects and 2/10 POP subjects (p = 0.48). Conclusions: Sacrospinous ligament and the ischial spines couldn’t be reliably visualized among women with or without pelvic organ prolapse using endovaginal ultrasound, although the structures are visualized more in some of the non-prolapsed women. The sacrospinous anchoring device demonstrated accurate placement by cadaveric dissections.

The Journal of China Universities of Posts and Telecommunications 2008年第4期15卷 19-23页

The layered maximum a posteriori （L-MAP） algorithm has been proposed to detect signals under frequency selective fading multiple input multiple output （MIMO） channels. Compared to the optimum MAP detector, the L-MAP algorithm can efficiently identify signal bits, and the complexity grows linearly with the number of input antennas. The basic idea of L-MAP is to operate on each input sub-stream with an optimum MAP sequential detector separately by assuming the other streams are Gaussian noise. The soft output can also be forwarded to outer channel decoder for iterative decoding. Simulation results show that the proposed method can converge with a small number of iterations under different channel conditions and outperforms other sub-optimum detectors for rank-deficient channels.

The Asia-Pacific Society for Sexual Medicine （APSSM） was established in 1987 in Hong Kong as a regional affiliated society of International Society for Sexual Medicine （ISSM）, and its biennial meeting is held in different Asia-Pacific countries or regions biennially. The 14th PSSM was successfully held in Kanazawa, Japan on May 31-June 2, 2013. Professor mikio Namiki chaired this meeting. Attracted to the comprehensively well-designed scientific programm, nearly 500 delegates across the filed of urological surgery, andrology, reproductive medicine, endocrinology, spiritual psychology and geriatric medicine from all of the world came together and discussed the important and hot topics across the filed. Over 200 abstracts were presented. The active discussion and reaction in the meeting had to complete due to the limited time, but the resounding outcome and the lasting reflection will be kept for a long time in minds of all attendees. Here we summarize APSSM2013 as below.

荣获2004年诺贝尔文学奖的耶利内克是一个备受争议的女作家,她的作品主要以表现女权主义、抨击反犹主义和当今政治为主题。半自传体小说《钢琴教师》是她女权主义的代表作。作者试图通过一名女钢琴师在母女关系、男女关系上的种种不合常规的事件,来表达对男权世界的不满和自己对这个世界无可奈何的愤怒。文章主要从女主人公的母亲和爱情来分析作家表现女性受到男权社会压制的状况,并以此来达到对男权社会的控诉。
