In order to study the species composition of the earwigs  on coconut trees, 108 coconut  trees in  18 locations at Cần Thơ city and  7 provinces  in the Mekong delta and Can Tho city were surveyed  during  the period from August 2004 to March 2005 . Five species of earwigs were recorded, two most popular ones of which were studied for species identification and morphology description. Results showed that one of these earwigs is Chelisoches morio (Fabricius)(Chelisochidae) and the second one is Chelisoches sp. These two earwigs are of  the first time recorded from Vietnam; the second species perhaps new and the identification is continuing. The identification  of these  two  earwigs on coconut trees in Vietnam has a important significance in the ways to find out a good IPM model for controlling the coconut beetle Brontispa longissima and other insect pests inVietnam.

The separation of regional and residual anomalies of the gravity-field was carried out by Wavelet transform. Using orthonormal bases of Daubechies Wavelets at the appropriate level, we determine the local gravity sources. The results show that the performance of the discrete Wavelet transform (DWT) approach is comparable with the results that were achieved by the second vertical derivative method. The proposed method has been tested by using some theoretical models and a profile of gravity data of the Mekong delta - South Vietnam.

Water sampling was taken at the high and low tide in the late wet season and the early dry season. The results showed that water environment of Rach Ban is severely polluted. Especially, this problem  was more serious in the dry season than in the wet season. The water parameters such as: BOD5, COD, SS, H2S, NH4+, total coliform are drastically over Vietnamese standard for surface water quality (TCVN 5942 ? 1995). The household waste management and the environmental protection awareness from local people are not well done- throwing the wastes and constructing the unsanitary toilets on the canal. These activities reduce the surface area and the reservoir of canal, eventually influencing to the clearness capacity of canal.

Assessment of the status and analysis of farming systems in areas of changing farming systems of Ca Mau province was conducted in 6 sites of 3 districts of Thoi Binh, Cai Nuoc and Dam Doi. The concept of sustainable livelihoods framework (SL) combined with participatory rural appraisal (PRA) was used for analyses and assessment. Results showed that incomes and living standard of farmers increased after the changing period, but the shifting to rice-shrimp or extensive shrimp systems reduced diversity in the system, and showed declines of environmental quality, agricultural resources, increases of risks and diseases on shrimp/fish. Result also showed that using sustainable livelihoods framework improved better understandings of farming status and  farmer situations. If PRA reflects information at the community level, the SF provides logical analysis and more details at the household level. 

Study on farming of giant freshwater prawn (Macrobrachium rosenbergii) on rice fields was carried in Vinh Long province in 2003 and 2004. The first experiment was stocked postlarvae (PL15) with a density of 6 per m2. The second one was stocked juvenile (PL45) with a density of 4 per m2. Each experiment was practiced in two farming systems including alternative rice-prawn and integrated rice-prawn. Experimental plots sizes was from 5,000-7,500 m2. Prawn was fed commercial pellet and fresh feeds. The results showed that prawn production varied depending on farming systems and seed sizes. The integrated rice-prawn farming stocked postlarvae gave the production from 762-887kg/ha compared to 264-463 kg/ha of stocking juvenile. The alternative rice-prawn stocked postlarvae gave 1,081-1,485kg/ha compared to 504-599kg/ha of stocking juveniles.

Nowadays,VietnamandThailandare inching next to each other. So, researching diplomatic relations in the history ofVietnamandThailandis very important. In this essay, we only deal with peaceful relations ofSiamand Viet in thirty years of the beginning of the XIX century. At the same timeSiamand Viet settled problem of Chan Lap equadle and negotiate. On the outlook life of the Feudalism,Siamkingdom and theHuecourt maintained a friendly attitude nearly thirty years. It is very special. Thanks to the situation of continent Southeast Asian, was settled in thirty years of the beginning of the XIX century. This is still of great value in establing the peaceful relationls, settlement and cooperation between the two countries as well as among other countries in the Southeast Asian at present time.

In order to find out useful gene(s) controlling proteins with high nutritive values, surveys to collect two wild rice species,which were surveyed from 2001 to 2003 in many sites in the Mekong Delta of Viet Nam.Results showed that there were significantly genetic diverse among populations of these two wild rice species. The phenotypic diversity (Ho) was  0.65- 1.96 in O. officinalis species while O. rufipogon, was 1.03- 4.57 according to sites sampled. The genetic diversity value of O. officinalis species  was(HEP=0.52) lower than that of O. rufipogon species (HEP=0.66). Similarly, the sum of the effective number of alleles (SENA) values had the same trend. Within O. rufipogon species there were genetic diversity among sites sampled but  HEP and SENA values were different insignificantly. Many samples of O. rufipogon species were detected that they were very useful for rice breeding with high glutelin nutritive value.

Study on Pseudapocryptes lanceolatus Bloch, 1801 with two stocking densities: 10 and 20 fish m-2 was conducted in 6 ponds at Bến Tre province from 8/2004 ? 8/2005. Water quality parameters were appropriated for fish growth. The growth rate of treatment II (0.17 ? 0.22 g day-1) was higher than that of treatment I (0.09 ? 0.18 g day-1) after 15 days. It was converse from 30 ? 60 days. In treatment I, the survival rate was 18.6 % and the fish yield was 363 kg ha-1, conversely, the survival rate in treatment II was 23.4 % and the fish yield was 951 kg/ha. The profit of treatment II (9.875.000 VND ha-1) was higher than  treatment I (1.742.000 VND ha-1). Generally, the intensive culture system of Pseudapocryptes lanceolatus at 20 fish m-2 has low in put and effective system for farmers in theMekong Delta.

A study of incubated sugarcane tops for conservation and late use as feeds of ruminants was done at the experimental farm ofCanthoUniversityto evaluate nutrient content, in vitro digestibility and animal responses. It was a complete randomized design experiment with 4 treatments such as  sugarcane tops without chemical treatment (control), sugarcane tops treated with 1% ammonium sulfate (AS) in fresh , with 5% urea based on DM basis (U) and with 2% urea and 2% molasses (UM) and three replication. In general CP was significantly increased in AS, U and UM treatments compared to control. At 72 and 96 hour incubation theOMin vitro digestibility of the treated sugarcane tops of AS and U were significant higher than that of the control and UM. The color of Treated sugarcane top of AS was light yellow and flavor. It was quickly accepted by the cattle, while the Treated sugarcane top of U was light green, then after few days it was eaten by the animals.

A trade union is a large political and social organization of the working class voluntarily established under the leadership of the Vietnamese Communist Party.  It represents Vietnamese workers, is part of the political system ofVietnamand brings the benefits of socialism to workers. In the scope of this paper, we will get to know the role of the trade union in protecting the rights and legitimate interests of the workers.

Objective of this study is to determine the intensity of light and the concentration of sucrose in agar gelled MS medium for shoot formation of seedless watermelon (Citrullus vulgaris Schard.) in vitro. The experiment was carried out by a factorial design in randomized complete with 3 replications and 12 treatments that were combined between three light intensities (1200, 1500 and 1800 lux) and four sucrose concentrations (0, 10, 20 and 30 g/l). Results showed that the highest efficiency of shoot formation after 4 weeks occurring in the treatment MS medium contained 30 g/l sucrose with 0.5 mg/l BA and kept at light intensity 1800 lux. These shoots, that were strong, high and had many leaves, will be a good material for a new shoot multiplication, root information and acclimatization.

An electrical current system including four-electrode probes connecting with a Humusoft card and a computer has been made in Can ThoUniversity,Vietnamfor measuring electrical conductivity (EC) of the salinity solution flowing through a horizontal sand column. The system is low cost, compact and reliable for developing countries asVietnam. The experimental results with potassium chlorite solution show that there are linear relations between the calibrated EC measured by four-electrode probes and EC measured by a benchtop EC-meter.

In order to screen genetic purity and increase high quality of a famous seasonal rice, Tai nguyen, collected in Tien Giang province in 2002 was analyzed by protein SDS-PAGE technology at lab of genetics-breeding & applied biotechnology,collegeofAgriculture, Cantho university. Results from protein SDS-PAGE electrophoresis and field tests show that 2 elite  lines (TNCL-006 and TNCL-007) was genetic purity with high stable protein content (>10%), amylose content was lower 24%, yield was also higher than the control variety (>15%) while agronomic characteristics such as plant height, 1000 seed weight and others weren?t different significantly. These two high quality lines were suggested to released into seed production in Tien Giang province and its surround.

In view of enhancing decision-making mechanism meeting rapid demands, flexibility, and new opportunities of higher education, Vietnamese government needs to establish a better administrative environment/mechanism which take higher education institutions as a centered-base for the mechanism development. This environment will not only mobilize its creativities and activeness but also promote legal accountabilities of the institutions. Proposed solutions are placed on the government ?s allocation policies regarding individual managerial  activities; improving higher education?s competition and commitments; enhancing autonomy and inspection; accomplishing leverage policies together with flexible principles and harmony as well as uniting higher education?s autonomous awareness

Experiment was designed split-plot with three replications and 12 treatments which are combination of main plot by: three potassium fertilizer levels (80, 120 and 160 kg K2O/ha) and sub-plot: 2 forms of potassium combined with applied time (KCl, KNO3 applied 4 and 5 times/crop). Results showed that: (a) application of 160 kg K2O/ha gave higher results on marketable yield (4.7 t/ha), fruit weight (1.47 kg/fruit), Brix (12.0%), duration of shelflife (31.5 days), fruit flesh dryweight (10.4%) and benefit cost ratio (1.62) compared with application of 80 kg K2O/ha; (b) forms of potassium combined with applied time before harvest did not affect on total fruit yield, marketable fruit weight and shelflife. Muskmelon grown on alluvial soil in spring-summer season applied 160 kg K2O/ha with form of  KNO3 (at 4 and 7 days before harvest) and KCl applied 3 times (at early stage) gave high yield, quality and profit.

Results from an extensive study conducted in 3 selected provinces of Kien Giang, Soc Trang and Tra Vinh from August to December, 2003 showed that the internal problems among Khmer communities are low education and technical knowledge/skills, small land holding, poor resource endowment, slow reaction to changes, poor economic management capacity. The external difficulties they are facing are less opportunity to education, training, employment, low access to credit, information, poor infrastructure facilities. It is needed to improve the educational level and tecnical knowledge/skill for Khmer people, develop better infrastructure facilities, improve the implementation of social wellfare policies, speed up the economic development process to create job opportunity for Khmer people, improve the coordination of porvety reduction programs in more participatory, diverse and integrated manners.

Fifty tubers of each variety (Hong Đao and Tim Nhat), totally 100 tubers, were analysed by protein SDS-PAGE and Lowry methods in order to screen and strengthen, these two varieties approaching to increasing higher protein content. The result showed that Hong Đao variety were more diverse in protein phenotype (Ho=0.91), genotype (HEP=0.59) and sum of the effective number of alleles than those of Tim Nhat variety (Ho=0.18; HEP=0.34; SENA=0.51). Two lines No.7 and No. 8 of Tim Nhat variety had high yields (1,05-1,15kg/plant) with higher protein contents than the others (6.15-9.41%) were suggested to test and release into production. In addition, three elite lines of Hong Dao variety having high yield (0.85-1.2kg/plant) were kept on analyzing protein content for choosing the best one. Hai giống khoai lang Hồng Đào và Tím Nhật (mỗi giống 50 củ) đã được phân tích protein dựa trên kĩ thuật điện di protein SDS-PAGE và Lowry để thanh lọc và phục tráng theo hướng nâng cao hàm lượng protein. Kết quả cho thấy giống khoai lang Hồng Đào khá đa dạng kiểu hình Ho=0.91; đa dạng di truyền khá HEP=0.59; và tổng số alen có hiệu quả là SENA=1.42 trong khi giống khoai lang Tím Nhật ít đa dạng hơn (Ho=0.18; HEP=0.34; SENA=0.51) nên hiệu quả chọn lọc trên giống khoai lang Hồng Đào cao hơn. Hai dòng số 7 và 8 của giống khoai lang Tím Nhật có năng suất cao (1,05-1,15kg/dây), có hàm lượng protein (6,15-9,41%) cao hơn so với đối chứng (5%). Ba dòng số 1, 2, và 4 có năng suất cao (0,85-1,2kg/dây) của giống khoai lang Hồng Đào được tiếp tục phân tích hàm lượng protein để tuyển ra dòng ưu tú nhất

Nowadays, collaboration is our characteristic working style. In the renovation of teaching methods at universities, students have been given chances so that they can be accustomed to that working style, through lessons? content. Making collaboration between students in groups becomes popular in teaching and when talking about collaborative learning, people often think about learning in groups. However, to make conditions in which students can be best accustomed to and developed collaboration skills, we need to concern an other kind of collaboration ? collaboration between students and the community.

148 varieties were experimented and analyzed for milling quality, physical properties and cooking quality to identify varieties with good grain quality for production and export. The results showed that: the number of MTL rice varieties which showed good grain quality in the study were MTL 325, MTL339, MTL 352, MTL356, MTL364, MTL372, MTL378, MTL392,... Harvesting at 25 days after flowering 50% brought the highest percentage of head rice and lowest chalkiness. The percentage of milled rice and head rice in Winter-Spring crop was higher than that in Summer-Autumn crop, the ratio of chalkiness rice and amylose content on rice in Summer-Autumn crop was lower than Winter-Spring crop. The ratio of head rice in saline area was higher than in alluvial and acid soil area. Drying rice at 40oC in 7-8 hours brought the best ratio of milled  and head rice.

The paper will be interested in testing retail prices of freshwater fish products affected by market movements when a shock of market volatility is coming, and also investigating market co-movement between products researched. To aim objectives should be concerned, types of econometric models are used: (i) Univariate GARCH; (i) Vector Autoregression (VAR). Data used to analysis is daily retail prices of freshwater fish products such as Ba sa, Tra in pond, Tra in cage,Snack fish,  Tilapia with time series from 2/1/2004 to 30/06/2005, the source of data is from Branch of Commercial Promotion, Advertisement Information and Agricultural Extension Center, Angiang Department of Agriculture and Rural Development.

Tweenty bacterial strains isolated from roots and stem of wild rice, cultivated rice and weeds in rice field had similar characteristics to those of Azospirillum genus. Two specific primers 5?- GTA AAT CCA CCA CCT CCC -3? (forward) and 5?- TGT AGA TTT CCT GGG CCT -3? (reverse) were used to identify these strains. The results showed that 8/20 strains and the positive Azospirillum lipoferum strain had the same DNA band at the position of 400bp. Other strains did not have the same band with the control strain. Therefore, they were not belong to Azospirillum lipoferum species. Several studies need to be carried out to classify them before applying in the field.

Nowadays, in some developing countries, high school teachers are using a fairly special kind of assignment namely worksheet, especially in literature reading session, students use role sheets. This assignment provides students with the ability of reasoning, presenting a matter, and expressing  their perceived knowlege. On the occasion of visiting MichiganStateUniversityand doing our observation in some High Schools in East LansingCity, we had an opportunity to explore this kind of assignment. And then, during accademic year of 2003 ? 2004, in Shell Programme, we had tested to experiment this kind of assignment at 11A5  class of  Nguyen Viet Hong High School in Can Tho City. In this article, we mention some following matters: how to present role sheets, some kinds of role sheets, the role and the requirement of using role sheets, experimetal results in 11A5.

In order to evaluate the genetic diversities of Nhai and Lim Kim fish, 65 Lim Kim fishes were collected in Ha Tien town?s market, nine Nhai and 39 Lim Kim fishes in Can Tho city. All these samples were analyzed by protein SDS-PAGE method. Results showed that the genetic population of the Nhai species in Can Tho city were less diverse(Ho=0.57,HEP =0.1, SENA=0.11). The poor genetic diversity of the Lim Kim population in Can Tho city were also detected(0.94, 0.27, 0.38). In comparision to the Lim Kim  fish in Can Tho city, that of Ha Tien town were rather diverse ( 2.82, 0.53 ,1.11). The  sample of the Lim Kim  fish in Ha Tien town had the protein content far lower than of those at Can Tho City, in other words, the Lim Kim  fish inhabiting in fresh water taste better than  those in brackish water. Moreover, based on protein profile allowing us to name them as follows: Lim Kim in Can Tho is Hemiramphus canthoensis, Lim Kim in Ha Tien is Hemiramphus hatienensis. The above genetic diversification showed that the Lim Kim, Nhai species  are underway to be extincted.

abstractIn 1997 Asian crisis, there has been a surge of proposals for financial integration of Asian countries. An Asian Monetary Fund (AMF) was suggested by Japan in 1997 and the Chiang Mai Initiative (CMI) was agreed by the finance ministers of ASEAN+3 countries in May 2000. In addition, a major change has taken place in Asian countries due to traditional reliance on overseas borrowings and bank-intermediated financing. An increasing trend to view the direct issuance of securities, particularly bond issues by the government and the private sector, as a viable way of financing their projects, and of harnessing the budget deficit as an important and viable means of bringing about the emergence of a local debt market. The fact points out the relationship between the Asian countries has developed significantly, especially in regional integration of monetary and finance although there have been some obstacles on the way of cooperation.

A study was conducted to test the susceptibility of chloramphenicol (CHL) resistant bacterial isolates (n=196) originating from aquaculture farms to six antimicrobials. Results of antibiotic susceptibility testing showed that resistance to CHL alone was rare (2%). The majority of isolates tested (59%) exhibited multi-resistance to three or four antibiotics in addition to CHL. The most common profiles (34%) included resistance to CHL, ampicillin, tetracyline, trimethoprim/sulfamethoxazole with/or without nitrofurantoin. the CHL-resistant isolates (29%) were found to be relatively more susceptible to norfloxacin. Ninety?one percent of the resistant isolates were shown to possess a MIC to CHL between 512?³1.024 ppm. There is a statistical evidence (p

A study was carried out at An Giang University from April to June 2004 to determine the effects of the foliage of a wild legume bush Mimosa pigra on intake and nutrient digestion of growing goats. The experiment used four goats, of 11 kg initial live weight, in a Latin square arrangement of four treatments with 15 day feeding period. In every period one goat was assigned to a different treatment diet.  The control diet was composed of  Brachiaria mutica grass. In the diet MP15, 15% of grass dry matter was replaced by foliage of the legume; in diet MP30,  30% was legume and in diet MP45  it was 45%. DM and total  crude protein intake increased with level of mimosa in the diet.  Digestibility of all nutrients  varied between 68% and 73%.

Guarantee is the only guaranty personal in the system of obligation guarantee methods in Vietnamese Civil Codes.  In the context of the present Socialist-oriented market economy, this guaranty keeps improving its benefits in establishing comercial transactions. The new Civil Codes 2005 with many changes and modifications in many fields have  great effect on setting and ending the guarantee contracts and especially its impacts whose partners are legal entities in  bankcruptcy declared situation . Specific research of all rules which are related  to the above commercial transactions bases on analysing the rules of the Bankruptcy law 2004 and Civil Codes 2005 in force will bring us many advantages to put them into practice.

Micropropagation of many plants is achieved through the establishment of explants, their initial growth in vitro being followed by transplanting into greenhouse or field. Many plantlets die during this period. Therefore, after ex vitro transplantation plantlets usually need some weeks of acclimatization with gradual lowering in air humidity. If the ex vitro transplantation of plantlets is successful, the increase in their growth can be enormous. Results of present experiment showed that 3-week-old seedless watermelon plantlets were acclimatized with 83,33% success on a  mixture of husk- ashes and coconut fiber muck (1:1, v/v). These plantlets, that were strong, high and had many leaves, will be a good material for transplanting in the field.

A study was carried out in Soc Trang province from October 2003 to January 2004 to evaluate the current situation of agricultural extension system and propose some possible solutions for future improvement. Results showed that the agricultural extension activities have significant contribution to the agricultural and rural development in the province. However, there are some problems at the grassroot level organization, extension methods, coordination and linkage within extension system and with other related organizations that need to be solved.  There is a need to establish the well-organized grassroot system, improve the metnodology and institutional issues related to supporting policies, decentralization and regularly well management of local extension activities.
