中国是全世界处理民族关系、民族问题最成功的国家,民族识别为中国政府推行民族团结、民族平等、民族区域自治等政策提供了条件。中国民族识别的成功经验是世界各国借鉴的榜样。中越两国友谊源远流长,越南54个民族中有27个与中国为跨境民族,血脉相通。越南民族识别借鉴了中国许多成功经验并有自己特色。越南的民族识别工作,主要是由政府下属的民族事务委员会来主持进行。民族事务委员会通过在全国各地召开各类研讨会,逐一讨论并确定各民族成分。1979年,民族学界在此基础上确立了越南民族成分名单。20世纪70年代,经历了 20多年的抗美战争后,越南的国家财政主要用于战后恢复,国家并没有将民族识别的相关理论与成果进行系统整理出版。因此,这给了解越南民族识别的过程,相关依据和最终结果确立增加了难度。我是一个越南留学生,熟悉本国历史文化,选择《越南民族识别及与中国的比较》为硕士毕业论文,详细介绍越南的民族识别,可以为中国学者研究越南民族问题及中越跨境民族问题提供参考。本文共有五章,具体内容如下:第一章,越南的民族理论研究。本章主要概述越南民族与民族识别的基本理论。越南学界对马克思、恩格斯和列宁民族观点的理解,是越南民族识别理论基础。除此之外,越南民族学学者们还参考西方学界对于“民族”概念的基本观点,来补充越南民族识别的基本理论。另外,越南学界进一步讨论了“民族”和“族群”的概念,以明确区分这两个概念。这是民族识别工作的基本思路之一。第二章,越南民族识别依据的争论。越南民族识别工作不能脱离越南民族的历史,通过研究各民族历史是民族学学界认定民族的思路之二。越南历代王朝对民族问题非常重视,每个朝代都有相应管理民族的政策,既有怀柔,又有武力。古代越南政府对民族的政策有利有弊,留给后世许多经验教训。越南民族共和国建立后,以实地调查的经验,结合马列主义理论,以及选择性地吸收了世界各国的经验,确定了民族识别依据。第三章,越南民族识别的背景、方式、依据与过程。本章主要论述越南政府和民族学学界识别越南各民族的历史背景,实践依据、识别过程。第四章,中国的民族识别。本章讨论了中国民族识别的历史背景,认为1949年前绝大多数少数民族的身份没有得到承认,少数民族认同国家,希望得到承认。中国民族识别要解决的两大问题是第一次人口普查所报的400个民族,哪些是汉族哪些是少数民族?哪些是单一民族?哪些是民族支系?中国的民族识别依据是斯大林的“民族”定义,但在实践中又有所创新,中国民族识别经历了四个阶段。第五章,中越民族识别比较。中越两国山水相连,政治制度相同,发展道路相近,笔者想通过两国对民族识别工作的对比研究,找到两者在背景、依据、过程等方面的异同,并分析这些异同产生的原因,最终得出结论。

this research has used the L-band radar from ALOS-2 PALSAR-2 and field work data for evaluation of seasonal effects of backscattering intensity on retrieval forest biomass in the tropics. The effects of seasonality and HH, and HV polarizations of the SAR data on the biomass were analyzed. The dry season HV polarization could explain 61% of the biomass in this study region. The dry season HV backscattering intensity was highly sensitive to the biomass compared to the rainy season backscattering intensity. The SAR data acquired in the rainy season with humid and wet canopies were not very sensitive to the in situ biomass. Strong dependence of the biomass estimates with season of SAR data acquisition confirmed that the choice of right season SAR data is very important for improving the satellite based estimates of the biomass. this research expects that the results obtained in this research will contribute to monitoring of the quantity and quality of forest biomass in Vietnam and other tropical countries.

We present a comparative study of the control of group velocity in three-level atomic systems including Λ-, Ladder-, and V-types via spontaneously generated coherence(SGC) and relative phase of laser *** the steady regime, expressions of group index are derived as an analytical function of controllable parameters related to SGC and relative *** is shown that the group velocity can be further slowed down or speeded up under SGC in which modifications of group velocity due to the SGC in Λ-and V-systems are stronger than that in *** particular, when interference strength of SGC p increases from 0.7 to 1.0, the light propagation is switched from superluminal to subluminal modes(for Λ-and Ladder-systems) or from subluminal to superluminal modes(for Vsystem).In the presence of relative phase, the group velocity changes between subluminal and superluminal modes with a period of 2π.In resonant region, the largest positive value of group index reaches at the relative phase φ=π while the largest negative value of group index reaches at φ= 0 and 2π for the Λ-and Ladder-systems, otherwise, for the V-system the largest positive group index occurs at φ= 0 and 2π, and the largest negative group index occurs at φ=π.

Sixteen samples of surface and groundwater from the most southern part of the Hanoi city (Vietnam) has been taken and analyzed for the soluble major ions, namely Na+, K+, , Ca2+, Mg2+, Cl-, , and arsenic as well as molybdenum content along with isotopic composition of deuterium and oxygen (δ2H and δ18O), tritium activity, and δ13C in DIC. The stable isotopic composition of groundwater indicates the water in that area is recharged from the local meteoric and theRed River’s water sources. The mean residence time of the groundwater should be before 60-ies of the past century as its 3H activity ranged from LOD of the analytical technique (0.4 TU) to 2.1 TU only implying that As would not be related to its recent application. The concentrations of As in the water samples is weakly correlated with those of Fe2+ (R2 = 0.08) but it strongly did with the concentrations of bicarbonate (R2 = 0.80). Thus, bicarbonate seems to liberate As adsorbed on hydrous ferric oxides (Hfo) into water through the displacement mechanism. The surface adsorption-desorption of As could be proven by a strong correlation between As and Mo concentrations (R2 = 0.77). The bicarbonate formation in groundwater was thought to be, partly, due to the bio-mineralization of natural organic matter (NOM) by bacteria followed by the dissolution of calcite and/or dolomite present in the sediments. Evidence for the NOM bio-mineralization was found in the close relationship between δ13C and the concentration of bicarbonate in water. Therefore, the mobilization of As in groundwater of bicarbonate type in the southern part of Hanoi city seems to be not only due to the reductive dissolution of the Hfo but the bicarbonate displacement also should be considered.

Cassava peel has a lot of nutrients which can be utilized as fertilizer in agriculture. However, high cellulose contents may cause difficulty for organic digestion and slow down the nutrient absorption for plants. this study aims to reach the microorganisms or their combination for biodegradating the cassava peel waste. The initial result shows that after 21 days the glucose concentration in all samples was the highest during experiment times. The reducing glucose produced in mg/mL by the selected bacteria was 9.32, higher than the selected fungie of 1.57 mg/mL. The percentage degradation of cassava peel weigh was the highest for fungi which was 52% of weigh, respectively. Meanwhile, bacteria only degradated about 31.6% after 4 weeks. However, the combination between bacteria and fungi provides the highest glucose concentration, 19.29 mg/mL and digests 62% of the mass cassava in experiment. this study suggests that biodegradation of agro-wastes in the environment to reduce biomass waste pollution is very promising.

In this work,we investigate a classical pseudomonotone and Lipschitz continuous variational inequality in the setting of Hilbert space,and present a projection-type approximation method for solving this *** method requires only to compute one projection onto the feasible set per iteration and without any linesearch procedure or additional projections as well as does not need to the prior knowledge of the Lipschitz constant and the sequentially weakly continuity of the variational inequality mapping.A strong convergence is established for the proposed method to a solution of a variational inequality problem under certain mild ***,we give some numerical experiments illustrating the performance of the proposed method for variational inequality problems.

BFT （Biofloc Technology） has been currently applied in Cantho University to a number of targeted species from fresh-to marine and saline water species in the Mekong Delta, e.g. striped catfish （Pangasianodon hypophthalmus）, white leg shrimp （Litopenaeus vannamei）, tiger shrimp （Penaeus monodon） and Artemia Vinhchau strain （Artemia franciscana） for both in the lab-scales or production scales. The best growth and survival rate of striped catfish was obtained in 6%o. For white leg shrimp, the results indicated：（1） C （Carbon） source e.g. rice-flour or molasses supplementary based on the feed provided to promote survival, growth and shrimp biomass harvested; （2） it was fed less than 20% as usual but showed similar to those in the control; （3） combination of rice-flour and molasses at a ratio of 70：30 by weight of C and N （Nitrogen） in a ration of 15：1 enhanced shrimp survival and growth; （4） in intensive culture, shrimp could be against the infection of disease and end up with higher survival, growth in earthen ponds. For tiger shrimp, a set up for larvae till post larvae at different ratios of C and N and C：N of 30 PLI5 displayed with better survival rate （49.73 ± 7.07%） and production （74,596 ± 10.608 PL/m3）. Artemiafranciscana was set up at C：N = 10：1 and salinities from 35, 60, 80 and 100 ppt. After two weeks, there were no significant difference among treatment and the control （without biofloc） in term of survival and growth. Moreover, total embryos per female was not significant different with the control and even the number of embryos as cysts tended to be higher. BFT displayed its advantages when applied on culture system of different targeted species and there is no doubt that it could help to sustain aquaculture and save environment in the Mekong Delta in near future.
