| 5 | 基于刨煤机单刨刀截割试验的截割阻力模型研究显示文摘根据刨煤机刨刀截割煤岩阻力谱以及截割机理,辨识出刨头破碎煤岩的所受截割阻力,提出了基于单刨刀截割阻力、刨刀截割规律及运行参数来确定刨头瞬时截割阻力方法,建立刨头截割阻力试验-理论综合模型,给出了截割阻力模型算法。结果表明:当煤岩阻抗为225 N/cm、崩落角为30°、刨刀数量为14把时,刨头上的刨削阻力达到最大96.86 k N,变差系数达到最小0.509 53,载荷波动较小,有利于刨头刨削煤体,理论分析与试验结果基本吻合,截割阻力的特征和量值均有很好的复合度,单刨刀截割试验可反映出煤岩破碎的内在规律。 | 刘芮葭 Chu Viet Dung Nguyen Viet Tuyen | 2016 | 煤炭科学技术2016，44，6： | 6 |
| 6 | Occurrence of emerging flame retardants from e-waste recycling activities in the northern part of Vietnam显示文摘This study investigated the contamination status of 21 emerging flame retardants(FRs)in soils(n=32)and river sediments(n=8)from an e-waste recycling(EWR)site in the northern part of Vietnam.Among analyzed FRs,higher levels of decabromodiphenyl ethane(DBDPE)(NDe4200 ng/g dw),1,2-bis-(2,4,6-tribromophenoxy)ethane(BTBPE)(NDe350 ng/g dw)and Dechlorane Plus isomers(DPs)(NDe65 ng/g dw)were found in soils near EWR workshops and open burning places.The highest concentrations of DBDPE(20 ng/g dw),BTBPE(5.7 ng/g dw)and DPs(6.7 ng/g dw)were also detected in sediments collected from the middle of the EWR site.The levels decreased concomitantly with increasing distance from the EWR site.These results indicate that these FRs were released to the surrounding environment from improper recycling activities,such as manual dismantling of devices and open burning of e-wastes.Moreover,the estimated daily intakes of those FRs via soil ingestion were approximately ten times higher for children than adults.To our knowledge,this is a first comprehensive study on characterization of soil and sediment contamination by a series of emerging FRs at an EWR site in Vietnam. | Masayuki Someya Go Suzuki Alin C.Ionas Nguyen Minh Tue Fuchao Xu Hidenori Matsukami Adrian Covaci Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 5 |
| 7 | Analysis of monomeric and oligomeric organophosphorus flame retardants in fish muscle tissues using liquid chromatographyeelectrospray ionization tandem mass spectrometry:Application to Nile tilapia(Oreochromis niloticus)from an e-waste processing area in northern Vietnam显示文摘Using electrospray ionization tandem mass spectrometry combined with liquid chromatography(LC),a novel analytical method was developed to quantify eight monomeric organophosphorus flame retardants(m-PFRs)and three oligomeric organophosphorus flame retardants(o-PFRs)in fish muscle samples.The optimization and validation experiments indicate that the developed method can determine accurately the concentrations of analytes in fish muscle samples.The recoveries of analytes in fish muscle samples were in the range of 74-105%.The coefficients of variation of the concentrations of analytes in fish muscle samples were 0.6-8.9%.The concentrations of analytes in procedural blanks were below the limit of quantification(LOQ)values.Furthermore,the developed method was applied to the analysis of m-PFRs and o-PFRs in the muscle samples of tilapias collected from an electronic waste(ewaste)processing area in northern Vietnam.The concentrations of m-PFRs such as tris(2-chloroethyl)phosphate(TCEP),tris(2-chloroisopropyl)phosphate(TCIPP),and triphenyl phosphate(TPHP)were dominant among the investigated m-PFRs.The respective concentrations of TCEP,TCIPP,and TPHP were up to 160,300,and 230 ng g^-1 lipid weight,respectively,whereas those of o-PFRs were up to 10 ng g^-1 lipid weight.The results of this study indicate lower accumulation potential of o-PFRs compared with m-PFRs for the first time. | Hidenori Matsukami Go Suzuki Nguyen Minh Tue Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 5 |

| 9 | Univector field method-based multi-agent navigation for pursuit problem in obstacle environments显示文摘The pursuit problem is a well-known problem in computer science. In this problem, a group of predator agents attempt to capture a prey agent in an environment with various obstacle types, partial observation, and an infinite grid-world. Predator agents are applied algorithms that use the univector field method to reach the prey agent, strategies for avoiding obstacles and strategies for cooperation between predator agents. Obstacle avoidance strategies are generalized and presented through strategies called hitting and following boundary(HFB); trapped and following shortest path(TFSP); and predicted and following shortest path(PFSP). In terms of cooperation, cooperation strategies are employed to more quickly reach and capture the prey agent. Experimental results are shown to illustrate the efficiency of the method in the pursuit problem. | Le Pham Tuyen Hoang Huu Viet Sang Hyeok An Seung Gwan Lee Dong-Han Kim Tae Choong Chung | 2017 | Journal of Central South University2017，24，4： | 3 |
| 10 | 越南传统医药概况显示文摘传统医药在越南的医疗卫生系统中发挥着重要作用。越南传统医药(VTM)是以东方哲学和康复理论为基础的,其受到中医药的巨大影响,但是有一定程度的差异。VTM大多不是以科学证据为基础的临床视角看问题,而是基于草药多年使用经验提供的亚临床数据。为了提高用药安全性,传统草药的不良反应和相互作用的研究十分必要。越南政府十分支持传统医药的深入科学研究及其与西药之间的联用。现从VTM的历史进程、规范管理、与中药的对比、哲学背景等方面进行概述。 | Herman J Woerdenbag Tuyen Manh Nguyen Dien Van Vu | 2013 | 亚太传统医药2013，9，11： | 3 |
| 11 | Spatio-temporal changes of underground coal fires during 2008-2016 in Khanh Hoa coal field(North-east of Viet Nam) using Landsat time-series data显示文摘Underground coal fires are one of the most common and serious geohazards in most coal producing countries in the world. Monitoring their spatio-temporal changes plays an important role in controlling and preventing the effects of coal fires, and their environmental impact. In this study, the spatio-temporal changes of underground coal fires in Khanh Hoa coal field(North-East of Viet Nam) were analyzed using Landsat time-series data during the 2008-2016 period. Based on land surface temperatures retrieved from Landsat thermal data, underground coal fires related to thermal anomalies were identified using the MEDIAN+1.5×IQR(IQR: Interquartile range) threshold technique. The locations of underground coal fires were validated using a coal fire map produced by the field survey data and cross-validated using the daytime ASTER thermal infrared imagery. Based on the fires extracted from seven Landsat thermal imageries, the spatiotemporal changes of underground coal fire areas were analyzed. The results showed that the thermalanomalous zones have been correlated with known coal fires. Cross-validation of coal fires using ASTER TIR data showed a high consistency of 79.3%. The largest coal fire area of 184.6 hectares was detected in 2010, followed by 2014(181.1 hectares) and 2016(178.5 hectares). The smaller coal fire areas were extracted with areas of 133.6 and 152.5 hectares in 2011 and 2009 respectively. Underground coal fires were mainly detected in the northern and southern part, and tend to spread to north-west of the coal field. | Tuyen Danh VU Thanh Tien NGUYEN | 2018 | Journal of Mountain Science2018，15，12： | 2 |

| 20 | Comprehensive evaluation of dioxins and dioxin-like compounds in surface soils and river sediments from e-waste-processing sites in a village in northern Vietnam:Heading towards the environmentally sound management of e-waste显示文摘The management of electronic waste(e-waste),which can be a source of both useful materials and toxic substances,depending on the processing method,is important for promoting material cycling.In this study,we used the dioxin-responsive chemical-activated luciferase gene expression(DR-CALUX)assay combined with gas chromatographyehigh-resolution mass spectrometry to evaluate the levels of dioxin-like compounds in surface soils and river sediments collected in and around an e-waste-processing village in northern Vietnam.The WHO-TEQs(Toxic equivalents)of polychlorinated dibenzo-p-dioxins and dibenzofurans(PCDD/Fs),coplanar polychlorinated biphenyls(Co-PCBs),and polybrominated dibenzo-pdioxins and dibenzofurans(PBDD/Fs)in soils collected in January 2012 ranged from 0.29 to 310 pg/g(median 2.9 pg/g,n=32),and the WHO-TEQs in sediments ranged from 0.96 to 58 pg/g(median 4.4 pg/g,n=8).Dioxin-like activities(CALUX-TEQs[2,3,7,8-TCDD equivalent])in soils collected in January 2012,2013,and 2014 ranged from<30 to 4300 pg/g(median<30 pg/g,n=96),and the activities in sediments ranged from<30 to 4000 pg/g(median 33 pg/g,n=24).Dioxin-like compounds accumulated in samples collected around e-waste-processing areas such as open-burning sites and e-waste-processing workshops,and the compounds may be transported from their sources to surrounding areas over the course of several years.Some of the CALUX-TEQs,but not WHO-TEQs,values were higher than the maximum acceptable WHO-TEQs promulgated by various authorities,indicating that all dioxin-like compounds should be evaluated in samples collected from e-waste-processing areas.Our findings suggest that open burning and open storage of e-waste should be prohibited and that wastewater treatment should be implemented at each workshop to reduce contamination by dioxin-like compounds from e-waste. | Go Suzuki Masayuki Someya Hidenori Matsukami Nguyen Minh Tue Natsuyo Uchida Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Abraham Brouwer Hidetaka Takigami | 2016 | Emerging Contaminants2016，2，2： | 1 |
