    诉讼信托是兼具当事人和信托形式的一种制度,对公益诉讼领域的当事人适格扩张具有重要意义。我国尚未建立体系化的诉讼信托制度,仅在少数公益保护领域突破诉讼信托的禁止性规定。随着我国市场经济的迅猛发展,群体性、公益性的纠纷频繁发生,引起社会各界的广泛关注。公益诉讼信托制度具有独特的制度优势,将在纠纷解决中发挥重要的作用。本文通过界定诉讼信托及其相关制度的内涵,分析诉讼信托的理论基础,考察不同国家和地区对诉讼信托制度的态度,以寻求构建我国公益诉讼信托制度的具体路径,完善公益诉讼当事人制度。除引言和结语外,全文分为四章。 第一章辨析诉讼信托及与之相关的概念。第一节介绍诉讼信托的定义及特征,并引出公益诉讼...Litigation Trust is a kind of trust system as well as a special form of litigant, which is important to the expansion of standing in Public Interest Litigation area.

    以厦门海域采集到的鱼卵、仔稚鱼为研究对象。首先根据形态学特征将其分为2种类型鱼卵和3种类型仔稚鱼,然后应用dnA条形码技术分析鉴定得到3个鱼卵种类和4个仔稚鱼种类。其中,6种鉴定到种的水平,分别为汉氏棱鳀(THrySSA HAMIlTOnII)鱼卵、颈带鲾(nuCHEQuulA nuCHAlIS)鱼卵、纹缟鰕虎鱼(TrIdEnTIgEr TrIgOnOCEPHAluS)仔鱼、髭缟鰕虎鱼(TrIdEnTIgEr bArbATuS)仔鱼、斑鰶(kOnOSIruS PunCTATuS)仔鱼和鲬(PlATyCEPHAluS IndICuS)稚鱼;1种鉴定到属,即双边鱼属(AMbASSIS SP.)鱼卵。研究结果表明,将鱼卵、仔稚鱼鉴定到种的水平,绝大多数都需要借助于形态学之外的手段,尤其是形态特征表现相近的鱼卵。而dnA条形码技术采用自动化和标准化应用系统,能有效地对形态特征相似的鱼卵、仔稚鱼进行种类鉴定,具有准确性高、重复性好、人为误差少等优点,已成为传统形态学物种鉴定的强有力补充,在鱼类生物多样性研究中具有广阔的应用前景。This research focus on identification of fish eggs and larvae collected in Xiamen waters.The samples were distinguished to 2 types of fish eggs and 3 types of fish larvae by morphological characters and were identified as 3species fish eggs and 4 species fish larvae by DNA barcoding technology.In which,there were six species and one genus were identified,including Thryssa kammalensis egg,Nuchequula nuchalis egg,Tridentiger trigonocephalus larva,Tridentiger barbatus larva,Konosirus punctatus larva,Platycephalus indicus larva and Ambassis sp.egg.The results showed that molecular technology was necessary in identification of fish eggs and larvae to species,especially those species without enough morphological characters.By using automation and standardization system,DNA barcoding technology can identify the species of fish eggs and larvae effectively.This technology with the advantages of high reliability,excellent repetition and less error is a powerful complement for traditional identification by morphology and has wide application prospects in the study of ichthyoplankton diversity.福建省自然科学基金资助项目(2011J05116); 广西红树林保护与利用重点实验室系统性研究课题(GKLMC-201307

    通讯作者(E-mail: [email protected]; Tel: 0592-2186486)。[中文文摘]用两个解剖针挤压胡萝卜花粉使其破裂释放出精细胞。用酶解-解剖方法分离胡萝卜胚囊中的卵细胞、助细胞和中央细胞。胡萝卜胚珠先在酶液中酶解40~50min,然后将其转移到不含酶的分离液中用解剖针解剖胚珠。将胚珠的合点端切破,轻轻挤压胚珠的珠孔,卵细胞、助细胞和中央细胞即可逸出。在最佳条件下,20min可从20个胚珠中分离出5个卵细胞。对分离胚囊细胞的渗透压和酶液成分进行了筛选。分离出的卵细胞用显微操作仪收集。胡萝卜精、卵细胞的成功分离为在双子叶植物中进行离体受精探索创造了条件。[英文文摘]Carrot (Daucus carota L.) two sperms could be released by squeezing pollen grain using two dissecting needles. Viable egg cells, synergids and central cells of carrot were isolated using enzymatic digestion and mechanical dissection. The ovules were digested in enzymatic solution for 40–50 min, and then transported into the isolation solution without enzymes to dissect. When dissected ovules were sliced from their chalazal ends,eggs, synergids and central cells could be released by gently pushing ovule micropyle part. In optimal isolation condition, 5 egg cells could be isolated from 20 ovules during 20 min. The osmolality and enzymes in the enzymatic solutions were screened. The isolated egg cells could be collected using micromanipulator for preparation of molecular biology of egg cell of carrot. The isolation of egg cell of carrot will make a great chance for in vitro fertilization in a dicot plant.公益性行业(农业)科研专项经费(200903016);国家自然科学基金(31170289

    由于对畜禽粪便的处置和管理不当,氮、磷养分随粪便大量流失,不仅带来日益突出的环境问题,还造成了资源的浪费。目前国际上多采用养分平衡方法研究和评价畜牧养殖场养分流失状况及其潜在的环境风险程度。选取福建省九龙江流域92家养猪场,采用养分平衡分析方法研究了该流域养猪场养分流失状况及主要影响因素。结果表明:大部分养猪场的氮磷养分输入量远远大于养分有效输出量,表明养分大量流失,养殖系统的环境风险程度极高;随着养猪场规模的增大,氮、磷的不平衡程度呈下降趋势;生态型养殖模式有利于促进资源综合利用,减少养分流失;加强对粪肥和饲料管理有利于促进畜禽养殖场的氮、磷养分平衡。Huge losses of nitrogen and phosphorus from the livestock production systems are known as the waste of resources and the sources of the environmental quality problems. Nutrient balance at farm level is an important tool to study the environmental problems associated with livestock production. A nutrient balance was constructed for 92 swine production systems of Jiulong River watershed, Fujian Province. The majority of the farms exhibited substantially greater nutrient inputs than nutrient managed outputs and it was in the status of an overaccumulation of nutrients; the nutrient imbalance decreased with farm scales; ecological production was a preferred mode to make better use of resources and decrease the losses of nutrients; management of feed and manure was helpful to balance the nutrients of livestock farms.福建省重大科技项目(2002H009)资

    研究了传统白光lEd与蓝光激发的球冠形远程荧光粉白光lEd在不同电流、不同热沉温度下的发光性能,并对其机理差异展开了探讨。实验结果表明:随热沉温度和驱动电流的上升,传统白光lEd的量子效率和电光转换效率急剧下降,并导致其y/b比(yEllOW/bluE rATIO)下降,相关色温上升。而在远程荧光粉白光lEd中,其量子效率、光转换效率和相关色温在相同实验条件下变化幅度都较小。由光强空间分布和y/b比空间分布可知,远程荧光粉白光lEd的光强分布呈类似蝠翼分布,且y/b比空间均匀性远大于传统白光lEd。Under different drive current and heat sink temperature,luminous performances as well as physical mechanisms were studied for both traditional phosphor-dispensing packaging white LED and blue light-converting hemisphere remote phosphor LEDs.With the increase of the heat sink temperature and the drive currents,the quantum efficiency and light conversion efficiency in the traditional phosphor-dispensing packaging white LED drop rapidly,which is responsible for the decrease of Y/B ratio(Yellow/Blue Ratio) and the apparent increase of CCT(correlated color temperature).However,the parameters of quantum efficiency,light conversion efficiency and CCT in blue light-converting hemisphere remote-phosphor packaging LEDs have little change under the same experimental conditions.In addition,the remote phosphor LEDs exhibit a batwing spatial luminous intensity distribution and the spatial Y/B ratio distribution is much more homogeneous compared with the traditional phosphor-dispensing packaging white LED.国家自然科学基金(11104230;61102030); 福建省产学研重大科技项目(2011H6025;2013H6024); 福建省重点科技项目(2012H0039)资

Here we focus on proteomics as a tool for the discovery of differentially expressed proteins closely related to the disease resistance. The leaves of rice cultivar Jiafuzhan (Oryzae sativa L. ) highly resistant to the disease, were infected by"89773-1- 1" strain of the Xooc with strong pathogenicity. Total proteins were extracted from the leaves sampled at two days after inoculation, and separated by two- dimensional electrophoresis. It was found that there were thirty- eight proteins expressed differentially, of which thirty-two were up-regulated, five down-regulated and one was "new". Of the thirty- eight responsive proteins, thirty-three were identified by MALD-I TOF-MS and database searching.Based on the predicted function, we grouped them into four clusters: signal transduction, defensive responses, substance metabolism and protein stabilization, which were involved in many resistant physiological react ions, including signal recognition and transduction, antioxidant react ion, carbonhydrate metabolism, cel-l wall reinforcement and phytoalexin biosythesis. In turn a complex signal transduct ion and metabolic regulative network in the resistant responses to the infection of Xooc was outlined in this work, and the molecular mechanism was revealed by differentially expressed protein/enzyme patterns during Xooc infection. In this study, eight R proteins and three pathogenesis- related(PR) proteins which might relate closely to the disease-resistance were found. This result provides us the basic information to further reveal the resistant mechanism and conduct functional cloning of the resistan-t related genes in rice to BLS.生物农药与化学生物学教育部重点实验室( 福建农林大学) 开放课题基金项目( KF0411
