The surface water in the southern of Hanoi capital is researched by identifying δ2H and δ18O stable isotopes together with EC, DO, BOD5, COD, TSS. Surface water samples for studying include the Red river, Nhue river and Kim Nguu river, thanh Nhan lake, Yen So lake and Van Quan lake were collected in the dry season (April) and the rainy season (August) in 2015. The stable isotope analysis results showed that the δ18O values is a range from -42.53‰ to -64.05‰ and, the δ2H values is the range from -5.09‰ to -8.79‰ under global meteoric waterline (in the water vapor region). The δ2H results of the rivers and lakes in the dry season are more negative than the rainy season with a small difference. The δ18O results of lakes in the dry season are more negative than the rainy season, but the δ18O results of river in the dry season are more positive than the rainy season. The results of the EC, BOD, COD, DO, TSS analysis showed that surface water environment has changed clearly in the two seasons and the contamination level in the dry season is usually higher than the rainy season. The lakes and rivers strongly influenced by human activities led to seriously pollution are Van Quan lake and Yen So lake, Nhue river and Kim Nguu river.

汉语惯用语是经过人们长期的使用、千锤百炼而形成的一种习惯的口头用语。它言简意赅、生动有趣,在现代汉语中占有极其重要的地位。惯用语在很大程度上依赖着特定的社会文化背景,因此惯用语比一般的普通词汇更富于文化内涵。动物惯用语不管是在汉语里还是越南语里都是惯用语中必不可缺的一部分,其数量相当丰富。通过借用动物形象来表达惯用语的意义,动物惯用语的文化内涵既浓厚又鲜明。本文选用《汉语惯用语词典》与《越南语详解与联想词典》、《越南语词典》、《越南俚语》收集1037条汉语动物惯用语与222条越南语动物惯用语作为研究对象。在前人研究的基础上,对汉、越动物惯用语进行对比分析找出异同点。本论文首先介绍选题缘由及研究意义、研究现状。其次,说明研究对象、语料来源与研究方法。其次,在前人的研究基础上,对汉、越惯用语进行界定,特别是对汉、越动物惯用语。对汉、越动物惯用语进行统计分类。把含有动物形象的惯用语分为三大类:家禽家畜类、野生动物类、图腾动物类。再次,本文对汉、越动物惯用语的语义方面进行对比,找出两者的对应关系。最后,根据汉、越两国动物的文化象征,对汉、越动物惯用语体现的文化内涵进行对比研究,找出异同点。通过分析的结果,可发现中国与越南两国的认知文化是有差异的,同一种动物会有共同的象征意义,也会有不同的象征意义。

The purpose of this study is to estimate the monetary value of the main environmental and external costs of Yali Hydropower Plant (YHPP) and to incorporate them into the financial viability indices of the plant, namely its net present value and electricity price. The results were found that if the electricity price is kept at its original level of 5.2 US cents/kWh to cover direct costs only, the net present value of the plant would be reduced to about 27% by incorporating environmental and external costs. Alternatively, the electricity price would have to be increased to 5.68 US cents/kWh in order to cover the full costs of YHPP and to maintain the original net present value. The main policy recommendations are: Government regulations should require that the financial analysis and appraisal of all future electricity sources include the full cost of these schemes, including not only direct costs but also environmental and external costs related to preventing or mitigating the environmental impact caused by them. An appropriate financial mechanism should be established to allocate the revenue from full cost electricity pricing to a fund to cover the environmental protection and compensation costs.

HIV/AIDS is still an important public health issue in Vietnam and other developing countries. In Vietnam, Community-based organizations (CBOs) were officially considered as the key partners to approach vulnerable groups at high risks of HIV infection since 2010. Funds for HIV/AIDS prevention and control are facing difficulties due to rapid reduction by international organizations, while domestic funding has not yet met the demand, especially funding for prevention and communication activities. Our study aimed to assess the fundraising capacity of several CBOs in Ho Chi Minh City, Vietnam and analyze the challenges that they are facing now and in future in their work of HIV/AIDS management for community. The 03 typical and representative CBOs (G3VN, Smile and Strong Ladies) were chosen in our cross-sectional descriptive study. The electronic questionnaire was about fundraising reports over 3 years (2017-2019), organization structure (staff, mission, strategies) and the advantages and disadvantages in fundraising. Funds received over the year increased in total, but unstable in each projects. To have more funds, CBOs must invest time and money to have professional staff in fundraising and writing proposals. To meet requirement and survive, some CBO shifted to social enterprises and faced many difficulties in laws when being treated like profit companies. In Vietnam context, the key challenges which affect the role of funding are including: 1) Legal status;2) Small scale;3) Capacity of fundraising (finding calls, writing competence proposals);4) Fewer funds on HIV/AIDS. In future, we should pay attention in scaling up and building fundraising capacity for CBOs in order to help them in applying for international funds in community projects or even in HIV/AIDS research for CBOs, social enterprises in the context of funds for nation-level phased out of Vietnam.

为了改善渤海湾海洋疏浚泥渗透性差和排水固结时间长的不足,引入化学絮凝结合真空预压的地基处理方法.首先分析了山东东营地区疏浚泥的矿物成分与物理性质,然后采用两种不同的絮凝剂进行了沉降柱试验与真空预压模型试验.结果表明:絮凝剂APAM添加量越大,混液面沉降速度越快,在添加量为15%时速度最快,约5 min内沉降基本稳定;絮凝剂CaO添加量越大,混液面沉降速度越慢,当添加量越过某一值(10%)时,最终混液面基本保持不变;真空预压排水速率并非絮凝剂添加量越大越快,絮凝剂CaO添加量为0.6%时速率最快,絮凝剂APAM添加量为15%时速率最快.研究成果对于东营疏浚泥地基处理工程实践具有一定的指导意义.
