Tradition, Revolution, and Market Economy in a North Vietnamese Village, 1925-2006, Hy V. Luong Hy V. Luong
This book is a revised and expanded version of the previously published Revolution in the Village : Tradition and Transformation in North Vietnam, 1925-1988 on a Vietnamese village named Sơn-Dương, a rural community in the Red river delta in northern Vietnam. The idea for the book was originated from a life story of an ancient Sơn-Dương villager- Mr. Nguyễn Đắc Bằng, who was at that moment living in Toronto (Canada). The vivid story of his life along with historical events of northern Vietnam..
Vietnamese civic organisations: supporters of or obstacles to further democratisation? Results from an empirical survey
In political science and in development cooperation, civic organisations (COs) under authoritarian rule are usually seen as supporters of processes that move towards democratisation. However, these organisations are sometimes criticised for their support of those in power. Within this context, critics refer to the fact that many COs have, for example, authoritarian intra-organisational structures. This characteristic clearly limits their potential to be supporters of democratisation processes. In this paper, we proceed from the assumption that Vietnamese COs can be both supporters of democracy and organisations that help to maintain authoritarian rule; they can sometimes even be both at the same time. COs are "polyvalent" (Kößler). More concretely, what COs are and which role(s) they play in the political system is mainly but not exclusively dependent on the impact the state has on them, and is at the same time dependent on the effects that those organisations have on the state.The results from an empirical survey, supported by the German Research Council (2013-2016) and carried out as a co-operation between the Institute of Asian Studies/GIGA Hamburg and the Vietnam Academy of Social Sciences, suggest the following: - Most Vietnamese COs are hierarchically structured, if not organised in an authoritarian way. They are not "schools of democracy", in the sense of Tocqueville. - Most Vietnamese COs that have engaged in the welfare provision sector, either willingly or unwillingly, have helped to foster the foundations of authoritarianism. - In the field of economic policies, the COs invited by the state to participate in and contribute to the formulation of policies do help, overall, to secure existing power structures, even though these organisations also help change various economic policies and even though their activities produce some democracy-promoting effects. - In the policy field of gender equality, women's rights, and rights of sexual minorities, the mass organisation Vietnam Women's Union supports the state's respective discourse. Some NGOs active in this policy field are doing both: They support and criticise the state's discourse on gender norms and the rights of sexual minorities.In the conclusion, we answer the question of which Vietnamese COs can be seen as supporters of further democratisation and which can be classified as obstacles
EXTRACTION AND PROPERTY STUDIES OF COENZYME Q10 FROM RECOMBINANT AGROBACTERIUM TUMEFACIENS
In this report, some results of extraction and characterization of CoQ10 from recombinant A. tumefaciens are presented. Four different cell breaking methods (sonication, acidic treatment, ethanol treatment, and enzymatic lysis) in combination with the extracting steps were carried out to extract CoQ10 and the results showed that ethanol treatment was the most efficient method. Appropriate conditions for CoQ10 extraction were 25 oC, 24 hours incubation and ethanol solvent/biomass ratio of 10:1 (ml/g). Characterization of extracted CoQ10 showed that CoQ10 was sensitive to light, but stable in the temperature ranges of 4 – 60 oC and the pH range of 6.0 – 9.0. Obtained results in present study should be applied in the large scale for CoQ10 extraction, providing the CoQ10 product for testing production of functional foods
Under the State's Thumb: Results from an Empirical Survey of Civic Organizations in Vietnam
Civic organizations (COs) are neither a good nor a bad thing. They are not inherently fighters for democracy or supporters of authoritarian rule. The way they develop depends on the impact that various forms of state power have on them and on their influence on the state. Vietnamese COs appear to be no exception. When we examine just one direction of these interdependent and reciprocal relations, it becomes clear that under the constraints of the Vietnamese state's infrastructural power many Vietnamese COs develop features of intra-organizational authoritarianism; that they help to embed the state and the Communist Party more deeply within Vietnamese society; and, finally, that they contribute to bringing the society further under the control of the state and the party. However, this occurs to a very different degree depending on the type of CO. NGOs and faith-based organizations in particular, at least in the field of gender norms and practices, seem to resist the state's discursive power. This could imply challenges to the state's and the party's control of politics and society and leads the authors to draw far-reaching conclusions as far as developmental cooperation with and potential support for various types of Vietnamese COs is concerned
Dairy Value Chain In Vietnam: Evidences from Bavi Area
Dairy farming, in Vietnam, existed in the early twentieth century thanks to the favorable natural advantage. During many difficult periods, the Vietnam’s dairy industry has developed constantly and contributed significantly to the food needs ensuring. However, Vietnam’s dairy industry still could not satisfy the domestic milk demand. Retail milk prices in Vietnam are very high, whereas the price of milk sold by the dairy farmers is very low. The cause stems from the control of dairy companies in the quantity and quality of milk. Moreover, that control caused an imbalance in the profits and benefits of each actor in the dairy value chain. This study, hence, finds out the distribution of benefits, costs, value-added among the actors, and problems in the practical management in dairy milk value chain with specific focus on Bavi as the case study
Using cassava waste of the cassava starch processing as food for raising African Nightcrawler (Eudrilus eugeniae) to obtain vermicomposting and earthworm biomass
The raising earthworms by cassava waste is a useful solution to reduce environmental pollution caused by cassava starch processing. In this study, cassava waste (including cassava peel, cassava pieces and soil) was used as a food source for raising African Nightcrawler (Eudrilus eugeniae) with three experiments: E1, earthworms were raised in crushed cassava waste right after being discharged; E2, earthworms raised in crushed cassava waste that had been incubated with organic matter after decomposing microbiological preparation for the previous two weeks; E3, earthworms were raised in crushed cassava waste that had self-decomposed naturally for the previous two weeks. The cassava waste was decomposed naturally for 4 weeks for control. The results showed that the content of organic matter, humic acid and total nitrogen in organic cassava humus, obtaining from experiments, increased compared to the control; the total organic matter content reached from 10.4%-15.7%, higher than the control (8.2%) from 1.27-1.92 times, humic acid content reached 0.6 - 0.8% and total nitrogen reached 0.3%. Experiment 3 had the highest quality of humus (organic matter content 15.7%, total nitrogen 0.3%, humic acid 0.7% and fulvic acid 0.5%). The experiment 3 also had the highest earthworm biomass (3.6kg), increasing 30.5% compared to experiment 1 and 19.4% comparing to experiment 2. Therefore, experiment 3 was proposed for application in treatment of cassava waste at larger scale. The organic humus obtaining from raising earthworms by cassava waste can be used as raw material for vermicompost production. The earthworm biomass can be used as protein-rich food for domestic animals (such as chicken, tortoise, eel, fish, etc) or used as nutritious fertilizer.Nuôi giun bằng phế liệu sắn là giải pháp hữu ích nhằm giảm thiểu ô nhiễm môi trường do chế biến tinh bột sắn gây ra. Trong nghiên cứu này, bã thải sắn (bao gồm vỏ, đầu mẩu sắn và bùn đất) được sử dụng làm nguồn thức ăn giun đất Châu Phi (African Nightcrawler (Eudrilus eugeniae) với các thí nghiệm như sau: Thí nghiệm 1: Giun quế được nuôi trong bã thải sắn nghiền ngay sau khi được loại bỏ; Thí nghiệm 2: giun đất được nuôi trong bã thải sắn nghiền đã được ủ với chế phẩm vi sinh phân hủy chất hữu cơ trong hai tuần trước đó; Thí nghiệm 3: Giun đất được nuôi trong bã thải sắn nghiền được để tự phân hủy tự nhiên trong hai tuần trước đó. Đối chứng là bã thải sắn để phân hủy tự nhiên trong 4 tuần. Bên cạnh đó, bã thải sắn nghiền còn được ủ bằng chế phẩm vi sinh phân hủy chất hữu cơ trong 4 tuần để cung cấp thêm số liệu so sánh giữa các thí nghiệm (Thí nghiệm 4). Các thí nghiệm được theo dõi trong 4 tuần. Kết quả cho thấy: Kết quả cho thấy: hàm lượng chất hữu cơ, axit humic và nitơ tổng trong mùn sắn hữu cơ thu được từ thí nghiệm đều tăng so với đối chứng: hàm lượng chất hữu cơ tổng số đạt từ 10,4% -15,7%, cao hơn đối chứng (8,2%) so với 1,27-1,92 lần, hàm lượng axit humic đạt 0,6 - 0,8% và nitơ tổng số đạt 0,3%. Trong đó, thí nghiệm 3 có chất lượng mùn cao nhất (hàm lượng chất hữu cơ 15,7%, đạm tổng số 0,3%, axit humic 0,7% và axit fulvic 0,5%). Thí nghiệm 3 cũng có sinh khối giun quế cao nhất (3,6kg), tăng 30,5% so với thí nghiệm 1 và 19,4% so với thí nghiệm 2. Do đó, thí nghiệm 3 đã được đề xuất ứng dụng để xử lý phế thải sắn ở quy mô lớn hơn. Chất mùn hữu cơ thu được từ việc nuôi trùn quế bằng phế thải sắn có thể được sử dụng làm nguyên liệu để sản xuất phân trùn quế. Sinh khối trùn quế có thể dùng làm thức ăn giàu đạm cho vật nuôi (như gà, ba ba, lươn, cá ...) hoặc làm phân bón dinh dưỡng
Genetic variation and outcrossing rate of Dipterocarpus dyeri in the Tan Phu tropical rain forest (Dong Nai), Vietnam
Dipterocarpus dyeri (Dipterocarpaceae) is widely distributed in lowland rainforests in southeastern Vietnam. Due to over- exploitation and habitat destruction in the 1980s and 1990s, this species is listed as threatened. Understanding the genetic variation and mating rate among D. dyeri population that occurs in forest patches is necessary to establish effectively conservation strategies for this species. To conserve the species in tropical forests, genetic diversity and mating rate were investigated using eight microsatellites (single sequence repeat, SSR) as markers. All of the eight loci were polymorphic. A total of 36 different alleles were observed across the loci screened. The SSR data indicated high genetic diversity (NA = 4.5; HO = 0.542 and HE = 0.667) and high inbreeding value, FIS= 0,182. The mating system parameters were determined using the mixed mating model and the results indicated high outcrossing rate (tm=0.81 and ts=0.675) and lowselfing rate (0.19). Difference of tm-ts value indicated that inbreeding contributed to selfing rate for this species in the Tan Phu tropical rain forest. The results reflected that D. dyeri habitat in this area has been restored and the number of individuals was high, about 500 individuals. However, seedlings were not found so far in this study. These results indicated the importance of conserving of the genetic resources of Dipterocarpus dyeri species in the Tan Phu rain forest. The conservation strategy should include an establishment of an ex-situ conservation site with new big population for this species from all genetic groups, which might improve its fitness under different environmental stresses.
Oil pollution in the Vietnamese waters
Enumeration of hydrocarbon-degrading microorganisms (HDM) and their degradative capacity studies were carried out in area IV of South China Sea (Vietnamese water). Microbial most probable number (MPN) varied from 101 to 105 cell/ ml of surface seawater or gram of sediment. Some microbial communities and bacterial strains isolated from 97 collected samples show high hydrocarbon degradation and surfactant producing abilities. Preliminary results of our microbial study indicated that oil pollution in IV area was not found in 30 research stations. Slight oil contamination was observed in 28 survey stations
