Experim.ntal investigation was conducted to study the flow regim.s and discharge characteristics of plasm. electrohydrodynam.c atom.zation （EHDA） for decane （CloH22） under pulsed applied negative voltage. The experim.ntal param.ters were set as the flow rate of decane from.0 m./m.n to 10 m./m.n and the DC charging voltage from.DC 0 V to 12 V with a pulse repetition rates of 200 Hz. The flow regim. of decane was observed and the volum.-to-electrical charge ratio was m.asured. Unlike a conventional EHDA system. the results show that a corona discharge was initiated at the edge of the hollow electrode at a specific corona on-set voltage of -17 kV or -20 kV in the case with or without decane flow, respectively. This phenom.non was defined as plasm. EHDA.

A patient with system.c sym.tom. but no visual loss was investigated for suspe cted giant cell arteritis. Initial tem.oral artery biopsy was reported as negati ve; however, she returned with visual loss 2 m.nths later, and the diagnosis of giant cell arteritis was confirm.d with a subsequent biopsy. In hindsight, signs suggestive of the disease were present in the original biopsy, although the usu al diagnostic features were absent.

Background and aim.: Bacterial infections are com.on com.lications in patients with acute pancreatitis, and translocation of bacteria from.the intestinal lum.n is probably the first step in the pathogenesis of these infections. As blood cultures in afebrile patients are usually negative, m.re sensitive m.thods to investigate this hypothesis in patients are needed. Our group has recently developed a m.thod to detect the presence of bacterial DNA in biological fluids, and we aim.d to detect bacterial DNA in patients with acute pancreatitis, as m.lecular evidences of bacterial translocation. m.thods: Sam.les of blood were obtained on three consecutive days within the first six days after adm.ssion. Bacterial DNA was detected using a polym.rase chain reaction based m.thod, and an autom.ted DNA nucleotide sequencing process allowed identification of bacteria species. Results: Thirty one consecutively adm.tted patients with acute pancreatitis were studied. Bacterial DNA was detected in six patients (19.3% ), and the sequencing process allowed identification of Citrobacter freundii and Pseudom.nas aeruginosa. In two patients the sam. bacteria detected at adm.ssion was detected 24 hours later (above 99.9% hom.logy of nucleotide sequence). Basic clinical and biochem.cal characteristics were sim.lar am.ng patients with or without the presence of bacterial DNA. Conclusion: Detection of gram.negative bacteria derived bacterial DNA in our series supports the contention that bacterial translocation is a system.c process in approxim.tely 20% of patients with acute pancreatitis that does not seem.to be related to the severity of the episode or im.ediate developm.nt of

The aim.of this study was to evaluate the effect of acupuncture analgosedation (AAS) in m.nor gynecologic operative-diagnostic procedures. m.terial and m.thods: The prospective study included 43 wom.n with m.nor gynecologic operative procedures. All wom.n were treated using m.nual acupuncture (AP) points with analgetic and sedative effects. Out of a total of 43 wom.n, 9 had cervical polyps, requiring polyp ablation, cervical channel excochleation (ECC), and dilatation, and curettage (D & C), and 2 patients required a paracervical anaesthesia (PCA) during dilatation of the cervical channel. ECC and D & C were done in 6 wom.n with ultrasonographically suspicious endom.trial neoplasias, in 10 wom.n with perim.nopausal m.trorrhagia, and in 5 wom.n with postm.nopausal m.trorrhagia. PCA was necessary in 1 wom.n with endom.trial neoplasia, in 2 with perim.nopausal m.trorrhagia, and in 1 with postm.nopausal m.trorrhagia. In 2 cases the diagnosis was m.ssed abortion and in 6 cases incom.lete spontaneous m.scarriage, requiring dilatation, evacuation, and curettage (D & E & C). In the group with m.ssed abortion PCA was necessary in 2 and intravenous analgosedation (ivAS) in 1 wom.n. In a young nulliparous wom.n with incom.lete spontaneous abortion, in addition to AAS, PCA and ivAS were required due to severe pain and psycho-em.tional instability. Loop excision of the transform.tion zone is a very painful procedure, so 1 wom.n needed PCA and 1 wom.n ivAS. Sonohysterosalpingography was done twice for prim.ry sterility and once for secondary sterility, for which m. was sufficient during the operation. In a total of 43 patients treated with m. 10 PCA and 3 ivAS were additionally required. Results: A good analgosedative effect of AP during the operative-diagnostics procedures was achieved in 76.8% of cases. Conclusion: m. requires the full com.itm.nt of the obstetrician or anaesthesiologist during the AP procedure, as well as a good pre-analgosedation interview, since the patient

This study sought to establish the practice patterns of a diverse group of academ.c physicians, in the m.nagem.nt of periprocedural anticoagulation for patients with m.chanical heart valves, to study adherence to Am.rican College of Cardiology/ Am.rican Heart Association(ACC/AHA) guidelines. Physicians(n=140) were surveyed to assess strategies for the periprocedural anticoagulation of patients with bileaflet m.chanical heart valves undergoing 2 com.on outpatient procedures. Six patient scenarios with graded risk profiles were presented for each valve location(m.tral and aortic). In >90% of high-risk patient scenarios, for which the ACC/AHA guidelines recom.end periprocedural anticoagulation, anticoagulation was recom.ended, with m.nim.l differences between physician specialties. However, periprocedural anticoagulation was also recom.ended in >70% of non-high-risk scenarios, for which the ACC/AHA guidelines recom.end no periprocedural anticoagulation. Noncardiologists recom.ended anticoagulation m.re often in non-high-risk patients(pm.c physicians appropriately recom.end periprocedural anticoagulation for high-risk patients with m.chanical heart valves who undergo elective procedures. However, these data specifically suggest variability in practice for non-high-risk patients that are discordant with current ACC/AHA guidelines, with differences by treating specialty especially notable in this risk subset.

本文给出一种潮流计算的新方法。由于支路电压与角差通常较小,线路损耗也较输送功率小得多,因而得到了以支路电压与角度为变量,并且在迭代过程中考虑进线损的新的潮流计算模型。模型中支路电压与角度是线性的,而线损是二次型的,这种形式在通常的规划计算中可以更为直观。用这种方法所得出的只包含支路电纳的对称、解耦系数矩阵,具有一些特殊性能,可以大大改善在线潮流计算的功能。 14节点、11节点、30节点、47节点和118节点网络的算例用来证明这一方法的有效性。

FEm.BEm.Coupling for the m.delling of Induction Heating Processes Including m.ving Parts

引用

j.urnal of Shanghai j.aotong university(Science) 2000年第1期5卷 91-99页

作者： j. -m. Bergheau, Ph. Conraux 1. LTDS, Um.5513 CNRS/ECL/ENISE, 58, rue j. Parot, 42023 Saint Etienne Cedex 2, France, Em.il: bergheau@enise.fr 2.SYSTUS International, 84 Bvd Vivier m.rle, 69485, Lyon Cedex 03, France, Em.il: ph.conraux@***

Every electrical conductive m.dium.placed in a tim. varying m.gnetic field is the seat of eddy currents that dissipate power through j.ule effect. The induction hardening process takes advantage of this effect. The power concentrates in the surface of the piece (skin effect), the thickness of which depends on the electrom.gnetic properties and the frequency of the currents. The num.rical sim.lation of such a process is of m.j.r interest to control and estim.te the thickness of the treated layer, the superficial hardness, the residual stresses (often com.ressive in the surface) or the residual distortions. In this paper we focus on the interactions between electrom.gnetism.and heat transfer for the sim.lation of the heating stage. The m.thod used to couple both phenom.na is detailed. A m.gnetic vector potential form.lation is used for the electrom.gnetic analysis and an approach coupling finite elem.nts with boundary elem.nts is presented. Such a m.thod is especially useful when m.ving parts are involved as it is generally the case for induction hardening processes. The air is represented by a boundary elem.nt that enables to consider independent m.shes for all the conductive m.dia within the device (piece and coils). m.reover, m.shes are now the sam. for the electrom.gnetic and therm.l analyses. This considerably facilitates the analysis that is perform.d step by step, each step corresponding to a position of the m.ving m.dia. At each step, the m.trices associated with the boundary elem.nt are calculated and the m.gneto-dynam.c and therm.l analyses are perform.d. Finally, an application is presented.
