The study has assessed the denitrification performance of fermented and dark-fermented biosolids as external carbon sources using lab-scaled Sequencing Batch Reactors （SBRs）. This was done by adding fermented and dark-fermented biosolids into anoxic zones of two SBRs, and then assessing the change of effluent characteristics comparing to before adding and to a third controlled reactor. The results showed that by adding 150-170 mg rbCOD/L of either of the selected fermented biosolids, almost complete denitrification could be reached for tested SBRs （reduced from initial -20 mg NO3/L to 〈 1 mg NO3/L）. Finally, the experiment also found that the impact of NI-I4 components of fermented and dark-fermented biosolids onto the final effluent were much lesser than expected, where only less than 2.5 mg NH4/L were detected in the effluent, much lower than the added 5.0-5.7 mg/L.

This paper reports a study that used a matched-pair pre-test, post-test control group design to compare the impacts of IL （intensive listening） program and EL （extensive listening） program on the learners＇ listening proficiency based on the 30-day experiment. It is hoped that the study can help Vietnamese learners who study EFL （English as a foreign language） develop a positive attitude towards EL on one hand, and may motivate them to listen for pleasure on the other hand. This study may shed light on how to introduce EL into English foreign language classroom practice and how to maximize the students＇ exposure to suitable listening materials, which has been effectively adapted and reproduced, for the real classroom practice

文章以越南河内法式街区特色建筑群体如何保护为研究对象,提出它是河内城市化过程的产物,反映了越南社会吸收西方文化和建筑风格的过程,同时,法式街区还有较高的美学价值。由于它有较高的观赏价值、深厚的历史文化价值与有待开发的旅游价值,因此值得研究。结合法式街区正饱受多种侵害,造成法式建筑工程质量下降、功能丧失、面貌改变的状况,提出法式街区保护与修复的建议。

Using a panel data at provincial level from 2004 to 2007 via mixing several officially statistical publications, the paper finds that the trade reform has affected significantly to the productivity of manufacturing sector among regions. Additionally, the transparency level of local government has positive effects on manufacturing sector productivity, while state sector biased has constrained the development of manufacturing sector. Moreover, the policy on development human capital of local government does not support the expansion of manufacturing firms.

Our aim was to evaluate the quality of ejaculated and epididymal frozen-thawed pig sperm of endangered Vietnam native pig breeds. Ejaculated sperm was collected from live boars and epididymal sperm was collected from slaughtered boars of the MuongTe, Kieng Sat and Co BinhThuan breeds and frozen in 0.25 ml straws using a protocol established earlier for modern pig breeds. We evaluated the sperm quality after thawing in terms of motility and rates of viable and abnormal spermatozoa. Our results revealed that the sperm motility and rates of viable and abnormal frozen-thawed sperm were >30%, >44%, and 0.05). In the Co BinhThuan breed, the rate of pregnancy of ejaculated groups was similar to that of the epididymal group. In conclusion, the ejaculated and epididymal sperm of native Vietnamese pigs were successfully frozen. We succeeded in creating embryos in vitro and pregnant pigs after artificial insemination from frozen-thawed semen in three native Vietnamese pig breeds for the first time. The use of the ejaculated sperm improved the production of native pig embryos in vitro efficiency.
