1多硝基芳烃静电火花感度与爆速的关系(英)显示文摘通过测定32 种多硝基芳烃的静电火花感度,建立了50 % 发火能量 E E S 与爆速平方值的关系式。该式不仅体现了 Evans Polanyi Semenov 关系,而且表明在起爆、初始分解或由静电火花引起的能量转换过程中多硝基化合物分子初始分裂时化学机理的同一性。但电火花能转至分子反应中心的方式还不甚清楚。Vladimr ZEMAN, Jir KO?, Svatopluk ZEMAN (Department of Theory and Technology of Explosives, University of Pardubice CZ-532 10 Pardubice,the Czech Republic) 1999含能材料1999,7,3:8

4Natural orifice transluminal endoscopic surgeryvs laparoscopic ovariectomy:Complications and inflammatory response显示文摘AIM:To compare natural orifice transluminal endoscopic surgery (NOTES) vs standard laparoscopic ovariectomy in mini pigs with respect to technical aspects,complications and parameters of systemic inflammatory response.METHODS:This was a randomized,experimental,survival study.Ten female mini pigs underwent NOTES transgastric ovariectomy (NOTES group) and ten female mini pigs underwent laparoscopic ovariectomy (LAP group).A 'percutaneous endoscopic gastrostomy' approach with guidewire and sphincterotome was used for gastrotomy creation.The ovary was resected using standard biopsy forceps and a snare.The access site was closed using a 'KING' closure with a single endoloop and several clips.In the laparoscopic group,a three-port laparoscopy and an ovariectomy were performed with the use of standard laparoscopic devices.C-reactive protein (CRP),white blood count and interleukin (IL)-6 plasma levels were used as indicators of systemic inflammatory response.All animals were euthanized 28 d after surgery.RESULTS:All animals survived without complications.The mean procedure time was 41.3 min ± 17.6 min (NOTES group) and 25.7 min ± 5.25 min (LAP group,P < 0.02).Postmortem examinations demonstrated that 50% and 70% of animals were free of any complications in the NOTES and LAP groups,respectively.The remaining animals developed minor complications (adhesions) in a comparable frequency between the two groups.In the NOTES group,one animal developed a small intramural gastric abscess close to the gastrotomy site.A minor serous exudate that was present in 50% and 40% of the animals in the NOTES and laparoscopy groups,respectively,was not considered a complication.In both groups CRP levels increased significantly on the 2nd and 7th postoperative days (POD) and returned to normal after 28 d.On POD 2,an increase of CRP level was significantly higher in the NOTES group compared to the LAP group.Values of IL-6 did not differ from baseline values in either of the groups postoperatively.Interestingly,the platelet count decreased significantly on POD 2,but returned close to baseline values on POD 7 and PODs 28-30.CONCLUSION:Both NOTES and laparoscopic ovariectomies had a similar frequency of minor complications.However,the NOTES technique produced an increased systemic inflammatory response on POD 2.Jan Martínek Ondej Ryska Tereza Filípková Radek Dolezel Stefan Juhas Jan Motlík Monika Holubová Vladimír Nosek Barbora Rotnáglová Miroslav Zavoral Miroslav Ryska 2012World Journal of Gastroenterology2012,18,27:4
5Electric Spark Sensitivity of Polynitro Compounds. Part V. A Relationship between Electric Spark and Impact Sensitivities of Energetic Materials显示文摘The spark energy, E ES , required for 50 percent initiation probability of 41 polynitro compounds was determined. The relationships between the E ES values and impact sensitivity, expressed as drop energies E d of the 'first reaction', were established and discussed. The conclusion is made that depending on intermolecular interaction factors in crystals of energetic materials, the mechanism of impact energy transition to the reaction centre of their molecule can be differ from that of transition of energy of electric spark.VladimírZEMAN SvatoplukZEMAN2001含能材料2001,9,2:4

20利用卫星遥感估算捷克共和国Kruné Hory地区1972~1989年间针叶林覆盖变化显示文摘本文对位于捷克与德国边境受到严重污染的Krusne Hory山区1972~1989年间森林破坏的范围、速率及其空间特性进行了研究。利用卫星遥感数据与数字地形数据相结合,对森林破坏进行评估。结果表明:有50%的针叶林在这一时期消失;受影响地区位于海拔600与1000m及坡向朝南和东南的坡地;位于SO_2和NO_x的强污染点源下风向地区的森林受到严重破坏。森林破坏与距离点源的远近间关系不明确。1989年依据针叶脱落,应用卫星遥感对森林损害的估算结果表明:现存的308km^2针叶林中,被划分为受轻度、中度及重度损害的森林分别为79%、17%及4%。Jonas Ard Nancy Lambert Vladimír Henzlík Barret N.Rock 卢显富 1997人类环境杂志1997,26,3:1
