Try to Discuss the Forum Non Convenience Doctrine

在处理繁杂的国际民商事争议时，管辖权冲突往往成为一个棘手的问题。在限制各国国内司法管辖权的扩张及合理解决国际民商事管辖权积极冲突方面，非方便法院原则是一种重要的途径，其适用已经成为国际民商事诉讼领域的大趋势。本文从非方便法院原则的相关概念出发，探究其适用条件，结合普通法系国家有关该原则的合理规定，对未来我国确立非方便法院原则的立法提出相关建议。全文除引言和结语外，共分为四章: 第一章从非方便法院原则的产生和发展历史入手，陈述了非方便法院原则从无到有，从不完善到逐步成熟的过程。进而从普通法系国家对非方便法院原则的合理规定中提炼出非方便法院原则的本质，最终提出非方便法院原则的概念。 第二章站在...In dealing with complex international civil and commercial disputes,conflicts of jurisdiction is often a troublesome problem .Forum non convenience has become an effective system as a limited expansion of judicial power within countries in resolving the conflict of international civil jurisdiction. The application has become the international civil jurisdiction. In this paper,considering the relat...学位：法律硕士院系专业：法学院法律系_法律硕士(JM)学号：X200612008

性腺发育及年龄对养殖中华鲟抗氧化力的影响

以养殖的子一代(n=21)中华鲟为对象,研究了性腺发育及年龄对其抗氧化力的影响。结果表明:(1)1998年生子一代雌性(未达性成熟,性腺处于慢速发育阶段)和雄性(接近性成熟,性腺处于开始快速发育阶段)的睾酮和雌二醇/睾酮差异显著,雌性血清丙二醛水平显著低于雄性,而超氧化物歧化酶和谷胱甘肽过氧化酶的活力及超氧化物歧化酶/丙二醛值虽高于雄性,但二者间不存在显著性差异,雌性和雄性的丙二醛与超氧化物歧化酶/丙二醛之间相关性极显著(r=-0.915,-0.818,P<0.01);(2)雌二醇/睾酮值与丙二醛显著负相关,与超氧化物歧化酶/丙二醛显著正相关(r=-0.635,r=0.709,P<0.05),与超氧化物歧化酶、谷胱甘肽过氧化酶无显著相关性;(3)4个年龄组(4、8、11、12龄,未达性成熟)的超氧化物歧化酶和丙二醛无显著性差异,12龄组的谷胱甘肽过氧化酶显著低于其余3组,而超氧化物歧化酶/丙二醛显著高于其余3组,谷胱甘肽过氧化酶和丙二醛与年龄呈负相关(r=-0.547,P<0.01;r=-0.519,P<0.05),超氧化物歧化酶/丙二醛与年龄呈正相关(r=0.569,P<0.01)。这表明进入性腺快速发育阶段的雄性氧化应激水平明显高于处于性腺慢速发育阶段的同龄雌性;随着年龄增长,未达性成熟中华鲟的抗氧化力水平逐渐增强;使用以上指标作为亚健康群体的筛选指标和氧化应激的生物标志物时,应充分考虑监测群体性腺发育和年龄因素,以使参考指标更准确

More than 50 constituents were separated, characterized and quantified, of which 44 positively identified. The majority of the components were found to be monoterpenes and sesquiterpenes. Minor substances were mainly diterpene, alkane derivatives as well as the esters of varied acid. The dominating compositions were β-caryophyllene, germacrene D, β-pinene, α-cadinol, (-)-bornyl acetate, (+)-spathulenol, δ-cadinene, β-elemene, α-humulene, α-amorphene, α-terpinolene, β-bourbonene, α-muurolene, α-copaene, α-pinene, β-selinene, naphthalene, α-terpinene, cadina-1, 4-diene, β-farnesene, δ-3-carene, and camphene. Differences in compounds quantity and the relative proportions of main terpene of pine needles between seasons were analyzed by Mann-Whitney U test. The result shows that the most abounding compounds were found in April, and June was the next; most of the main terpene contents were not different significantly among seasons (P=0.05). Principal components analysis indicated that the profiles of young needles in September, mature needles in August and October, and samples from February and November might play important roles in interrelation study of different months.福建省自然科学基金 (B0 0 10 0 0 6 )资助项

Secado natural de raíces de yuca en pisos de concreto

以北京海洋馆驯养的野生和子一代中华鲟为对象,研究了养殖密度对中华鲟行为、免疫力和养殖环境水质的影响。结果表明：在养殖密度分别为2.7、2.4、2.0kg/m3的循环水环境中,中华鲟的泳层分布改变,体型小的中华鲟变化最大。3种密度环境对中华鲟食欲未有明显影响,对野生中华鲟和F1-1998的泳速和呼吸频率也未有明显影响。2.7kg/m3的密度下,F1-1998的超氧化物歧化酶和谷胱甘肽过氧化物酶活力、超氧化物歧化酶/丙二醛值下降,而丙二醛水平上升。在养殖密度为2.7和2.4kg/m3的水环境时,水体悬浮总细菌数量持续大于8 000cfu/100mL,年龄大的中华鲟,包括野生中华鲟和F1-1998中华鲟细菌感染。同期对水质监测结果表明,氨/铵、亚硝酸盐和浊度稳定,硝酸盐、磷酸盐和总细菌随养殖密度下降而降低,溶解氧、酸碱度上升,各密度组间存在显著性差异（p〈0.05）,硝酸盐、磷酸盐、总细菌与养殖密度存在着显著的正相关。实验表明,使用循环水养殖中华鲟,环境负荷对水体微生物和养殖鱼免疫力的影响是极为显著的。推荐最佳养殖密度为2.0kg/m3

一种家庭用营养均衡型配方食用油的 加热及烹饪稳定性Heating and cooking stability of a kind of nutrition- balanced formula oil for home use

通过模拟加热(180 ℃加热15、30 min)及家庭烹饪（炒青菜）过程，研究了一种富含不饱和脂肪酸、n-6/n-3脂肪酸比例适宜且有益脂质伴随物含量丰富的配方食用油的加热及烹饪稳定性。结果表明：配方食用油在加热或烹饪青菜时其酸值、过氧化值略有上升，但均远低于GB 2716—2018的规定；加热和炒菜过程中不会造成反式脂肪酸含量的增加，且苯并(a)芘含量远低于国标限量，说明在加热和炒菜过程中该配方食用油能够保持安全稳定；此外，配方食用油脂肪酸组成在加热或烹饪前后变化不大，n-6/n-3脂肪酸比例稳定，生育酚和总酚含量在加热和烹饪后下降幅度在35%以内，植物甾醇含量下降约12%。由此可知，配方食用油能够在常规家庭烹饪过程中保持稳定，是一种日常补充n-3多不饱和脂肪酸和有益脂质伴随物的有效途径。The heating and cooking stability of a formula oil enriched in unsaturated fatty acid, appropriate ratio of n-6 to n-3 fatty acids and beneficial lipid concomitant was investigated by simulating the heating(15,30 min at 180 ℃)process and home cooking(stir-frying vegetables) process. The results showed that the peroxide value and acid value of the formula oil increased slightly after heating and cooking, and both of them were below the limit of GB 2716-2016. Besides, the content of trans fatty acids did not increase during heating and cooking, and the content of benzo(a) pyrene was far below the national limit, indicating that the formula oil was stable during heating and cooking process. The fatty acid composition and the ratio of n-6 to n-3 fatty acid of the formula oil almost kept constant after heating and cooking. The contents of tocopherol and polyphenol decreased within 35%after heating and cooking, while that of phytosterol decreased by about 12%. Overall, the formula oil was stable in family cooking process, and it was a good way to supply n-3 polyunsaturated fatty acid and beneficial lipid concomitant
