1世界主要乳制品生产国的乳业制度与政策回顾显示文摘许多发达国家的牛奶生产者在政府干预行为中受益,因为政府干预行为提高了原料奶售价,并且政府建立牛奶生产配额制度用以控制生产过剩,明确市场保护价格。本文对加拿大、日本、澳大利亚和新西兰等主要乳业生产国的政策进行了回顾,阐述了不同乳业政策措施及其干预程度。路遥 王奇 蒋永宁 起建凌 王文杰 徐若英 Pavel Vavra 2012中国畜牧杂志2012,48,22:6
2Laparoscopic approach to retrorectal cyst显示文摘Retrorectal cysts are rare benign lesions in the presacral space which are frequently diagnosed in middle-aged females. We report here our experience with two symptomatic female patients who were diagnosed as having a retrorectal cyst and managed using a laparoscopic approach. The two patients were misdiagnosed as having an ovarian cystic lesion after abdominal ultrasonography. Computer tomograghy (CT) scan was mandatory to establish the diagnosis. The trocar port site was the same in both patients. An additional left oophorectomy was done for a coexisting ovarian cystic lesion in one patient in the same setting. There was no postoperative morbidity or mortality and the two patients were discharged on the 5th and 6th post operative days, respectively. Our cases show that laparoscopic management of retrorectal cysts is a safe approach. It reduces surgical trauma and offers an excellent tool for perfect visualization of the deep structures in the presacral space.Petra Gunkova Lubomir Martinek Jan Dostalik Igor Gunka Petr Vavra Miloslav Mazur 2008World Journal of Gastroenterology2008,14,42:4

4钼催化剂结构对其催化气相丙烯环氧化反应选择性的影响(英文)显示文摘考察了Mo基催化剂上空气气相氧化丙烯反应.从无机的和有机金属Mo前驱体出发,采用浸渍法和物理气相沉积法(PVD)制备了不同类型的SiO2负载氧化钼和Mo-Bi复合氧化物催化剂.透射电镜结果证实,所制催化剂上环氧化反应活性与其纳米结构直接有关.催化剂中出现部分或完全结晶的氧化钼相,它们与载体SiO2的相互作用较弱,使得反应生成环氧丙烷的选择性低于10%,而锚合在SiO2上的非结晶的八配位Mo物种上的环氧丙烷选择性达55%以上,此时丙烯转化率约为11%.不同形貌氧化钼的电化学表征结果证实了结构缺陷的重要性.另外,还讨论了Bi对氧化钼催化环氧化活性的直接促进效应.Martin Sustek Blazej Horvath Ivo Vavra Miroslav Gal Edmund Dobrocka Milan Hronec 2015Chinese Journal of Catalysis2015,36,11:2
