The result of the study contributes to enhancing and sustaining future livelihoods and food security in Vietnam vis-a-vis climate change. An innovative strategy based on marker-assisted backcrossing (mABC) was used to transform popular rice variety AS996 into the one can tolerate submergence while maintaining its original characteristics preferred by farmers and consumers. The submergence tolerance QTL SUB1 counts for up to 70% of the submergence tolerant and provides a marked improvement of submergence tolerance in all genetic backgrounds and environments tested so far. Parental diversity was carried out with 460 markers. Of which, 53 polymorphic markers were used for assessment on BC1F1, BC2F1 and BC3F1 generations. The best BC1F1 plant was P422 with highest recipient allele was 87.5%, while the additional chosen plants were P412, P428, P215 and P39 (81% - 84%). All these plants were used to develop BC2F1 generation. The six BC2F1 plants were used to develop BC3F1 and BC2F2 were the plants number P422-11 and P422-14 having 93.75% recipient alleles and P422-12, P422-3, P39-17, P39-25 having 92.25% recipient alleles. Total of 445 BC3F1 plants were confirmed the introgresion of SUB1 using ART5 and SC3. After three generations of backcrossing, application of mABC resulted in the best BC3F1 individual P422-14-177 with 100% of recipient alleles based on the number of 53 markers used with only the introgression size of SUB1 was 0.3mb between ART5 and SC3. Phenotyping was carried out on BC3F1 and BC2F2 of the selected lines. The survival ratio of these selected lines and IR64SUB1 were the same. It convinced the successfully introgress SUB1 into AS996 rice variety. The breeding line BC4F1 having 100% genetic background of donor variety is ready for develop new submergence tolerant rice variety ASS996-SUB1 to cope with climate change.

本文研究工作主要是关于用铬饼制备铬鞣液及其应用。铬饼是废铬屑用酶处理后的副产品，铬饼可以生产环保胶黏液。铬饼含40％-50％的无机固体，这些无机固体中还含有12％～15％的氧化铬。制备的5种不同铬液用于猪皮鞣制，鞣制后的猪皮革进行一系列的化学、物理机械性能（14种参数）的测定，所得结果能够与常规铬鞣液鞣制后的猪皮革相比较。结果表明，制备的鞣液可用于白色革的生产，并且相关的化学、物理机械性能可以与常规舶铬鞣液鞣制后的革相媲美。

温室气体（CO2）过量排放可以导致全球气候变暖,而碳捕捉与储存（carbon capture and storage,CCS）技术是一种减少CO2气体排放的有效措施。但存储在地下的CO2有泄漏的风险,如何快速监测CO2轻微泄漏点是一个值得研究的问题。该文通过野外模拟实验,研究草地和大豆在CO2轻微泄漏胁迫下的冠层光谱特征,构建CO2轻微泄漏点高光谱遥感探测模型。在2008年5月—9月于英国诺丁汉大学Sutton Bonington校区（52.8n,1.2W）进行了野外模拟实验。实验共设置16个小区,8个草地及8个大豆地,其中各有4个小区进行CO2泄漏胁迫。冠层光谱采用美国ASd光谱仪进行测量,草地测量了6次数据,大豆地测量了3次数据。实验结果表明,草地与大豆地的冠层光谱反射率在580~680nm波段范围内随CO2泄漏胁迫程度的增大而增大,且在整个试验期内都保持同样的规律,因此构建面积指数AREA（580~680nm）（光谱曲线在580~680nm波段范围内包围的面积）识别遭受CO2泄漏胁迫下的植被。通过J-m距离检验,发现该指数能够较好地识别出CO2轻微泄漏胁迫下center区与core区的草地,但对edge区草地的识别能力不足（J-m距离小于1.8）;该指数可以可靠且稳健地识别出遭受CO2轻微泄漏胁迫的大豆。该研究结果可为未来应用高光谱遥感探测CO2轻微泄漏点提供理论依据与方法支持。

Objective: To quantify more reliably the benefits and risks of monoamine oxidase type B inhibitors (mAOBIs) in early Parkinsons disease. data sources: Searches of the Cochrane Library, medline, Embase, Pubmed, and We b of Science for years 1966-2003, plus major journals in the field, abstract bo oks, and proceedings of meetings, for randomised trials comparing mAOBIs with pl acebo or levodopa. data extraction: Available data on mortality, motor complicat ions, side effects, treatment compliance, and clinician rated disability (for ex ample, unified Par kinsons disease rating scale) were extracted from 17 trial s and combined using standard meta analytic methods. Results: no significant di fference in mortality existed between patients on mAOBIs and control patients (o dds ratio 1.13, 95%confidence interval 0.94 to 1.34; P=0.2). Patients randomise d to mAOBIs had significantly better total scores, motor scores, and activities of daily living scores on the unified Parkinsons disease rating scale at three months compared with patients taking placebo; they were also less likely to nee d additional levodopa (0.57, 0.48 to 0.67; P develop motor fluc tuations (0.75, 0.59 to 0.95; P = 0.02). no difference existed between the two g roups in the incidence of side effects or withdrawal of patients. Conclusions: m AOBIs reduce disability, the need for levodopa, and the incidence of motor fluct uations, without substantial side effects or increased mortality. However, becau se few trials have compared mAOBIs with other antiparkinsonian drugs, uncertaint y remains about the relative benefits and risks of mAOBIs. Further large, long t erm comparative trials that include patient rated quality of life measures are n eeded.
