Increased urbanization coupled with increased reliance of urban communities on rural areas for ecosystem service provision is a challenge faced by many nations. The ability of urban households to directly support restoration efforts in surrounding rural regions represents an underappreciated funding stream for ecological restoration. This study explored the willingness of urban households to support forest restoration in Vietnam. We surveyed 211 households (HHs) in the capital city Hanoi, Vietnam. A Maximum Likelihood Estimator (Mle) model allowed us to obtain the parameters of our model and quantify mean Willingness-to-Pay (WTP) for a program of forest restoration in addition to identifying factors influencing the decision of WTP. Generally, over forty percent of the households surveyed are willing to pay for forest restoration and the mean value of WTP is 37,830 VND ($1.73) per household per month. WTP depends on endogenous and exogenous factors including level of education, income, female-to-male ratio in the household, attitude toward payment for monthly electricity consumption, and awareness of payment for environmental service. Our results suggest that urban household’s demand for forest restoration is real, and represents an untapped source of restoration funding. Policy-makers should take actions to apply charges on water bills to turn this potential into reality for restoration projects in Vietnam if the benefits from restoration outweigh the costs based on our findings.

The most common reference electrode (RE) which is used in electrochemical measurements is the Ag/AgCl electrode. In this study, we present a novel solid-state Ag/AgCl planar electrode that was coated with a thin layer of Graphite Oxide (GO) as a protective layer. The Ag/AgCl planar electrode was fabricated by using the photolithography and lift-off method combined with the Ag[NH3]2Cl complex. The GO was produced by Hummer’s method and was deposited on top of the Ag/AgCl layer by drop-casting method. The layers of the fabricated reference electrode were characterized by micro Raman spectroscopy, Scanning Electron Microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDX). The responding time of the planar electrode was short and the signal was more stable in comparison to the plainAg/AgCl electrode. The Open Circuit Potential (OCP) measurement with the fabricated electrode as the RE and the platinum electrode as the working electrode in electrolyte solutions which had various pH values was performed with a linear response in pH ranges from pH 5 to pH 8 and the linear correlation coefficient (R^2 = 0.9899). Moreover, the coating of the GO layers also enhanced the durability of the modified electrode. The results showed that the modified Ag/AgCl electrode with a thin layer GO as the protective layer could be used as plana REs for the potentiometric sensors.

An online survey addressed to members listed in the European Cooperative Programme for Crop Genetic Resources Networks Working Group on Graithe current problems in the management of GL germplasm, to work out the criterian legumes and Grain legumes （GL） germplasm managers and breeders was carded out to pinpoint and decisions involved in the implementation of regeneration procedures and to identify strategic areas where further research is required. The survey was divided into three sections：（1） germplasm collection details and current status of the regeneration needs; （2） assessment over the understanding of basic information required to carry out appropriate regeneration procedures such as the breeding systems, the pollination requirements and pollinating agents, the isolation techniques and regeneration facilities; and （3） assessment of different options, in addition to ＂ex situ＂, such as ＂in situ＂ and ＂on farm＂ conservation. Obtaining, collating and analysing different kinds of existing data on mating system of GL species, effective pollination control methods and isolation facilities by species and location is one example of a priority issue. The GL community makes a clear request for greater support for the development of well-designed methodologies of regeneration that maintain the genetic structure of populations and that the optimum regeneration strategy is most likely to be achieved through integrating pollinators with the regeneration procedures. A major concern of the GL community is the lack of empirical scientific information on the most suitable pollinator agents.

水果是越南重要的农产品之一,得益于优越的地理位置,越南水果具有品种多、质量好以及价格低等众多优势。经济一体化趋势的发展使各个国家和地区之间贸易交流不断密切,因此每年都有大量的越南水果运输到世界上各个国家和地区,为越南对外贸易的发展做出了非常大的贡献。中国-东盟自由贸易区的建立使得中国同东盟国家的贸易往来不断密切,广西作为越南水果进入中国市场的主要通道,在两国水果贸易发展中有着至关重要的地位,同时物流运输问题也就成为影响越南水果出口广西的主要问题之一。随着现代物流业的发展和进步,越南到广西物流的现状已经无法满足其水果贸易的出口以及未来贸易发展的需求。因此优化越南水果出口广西物流路径,构建现代物流系统,成了目前越南水果出口广西主要的问题。基于此,论文运用文献综述法,SWOT分析法以及多学科综合等研究方法。首先对选题的背景和意义进行了说明,同时对论文的理论和已有文献进行了整理和阐述,在此基础上,论文对越南水果出口广西的现状以及物流业发展现状进行了深入的分析;第三章里,论文运用SWOT分析法,分别从优势、劣势、机遇和挑战四个角度阐述了越南水果出口广西物流的现状;第四章论文从安全最优、通关口岸最优和通关时间最优三个方面分析了越南水果出口广西的路径;第五章里,论文根据目前越南水果出口广西物流的现状和存在的问题,提出了相应的措施和建议,以促进越南水果出口广西物流业的发展以及越南和中国贸易的不断发展和进步。

Objectives. The aim of this study was to investigate the effects of orthopaedic soles on the body posture. Methods. Forty-eight runners (21 men and 28 women) maintained a standing-up position on both feet with bare feet with neutral soles and orthopedic soles which contained bilaterally a podiatrist element of 3 mm height behind the metatarsal heads (Metatarsal Retro Capital Bar, MRCB). Stabilometric, plantar pressure and kinematic data in the sagittal plane on both sides were measured at 40 and 60 Hz, respectively. The position of the center of pressure on the anteroposterior axis (YCoP), the forefoot plantar pressure (FPP) and the anteroposterior position of the knee (Yk), the hip (YH), the shoulder (YS) and the ears (YE) with respect to the vertical axis passing through the joint of the ankle were determined for each experimental condition. Findings. The addition of a MRCB orthopedic element induced in backward displacement of CoP, hip, shoulder and ears (p CoP and FPP changes were significantly correlated with YH, YS and YE changes (p Conclusion. These results suggest that the addition of an orthopedic element located behind the metatarsal heads influences the overall position of the body and can help podiatrist in the care of their patients.

The thermal neutron capture gamma radiations for 51V(n, g)52V reaction have been studied at Dalat Nuclear Research Reactor (DNRR). The gamma two-step cascade transition was measured by event-event coincidence spectrometer. The added-neutron binding energy in 52V was measured as 7.31 MeV. Energy and the intensity transition of cascades were consistent with prediction of single particle model. Furthermore, the spin and the parity of levels were confined.

语蚀,即语言磨蚀（英文:Language Attrition）,指语言运用能力的减退。在语言发展历程中,习得与磨蚀并存。语言磨蚀就其实质而言,是语言习得的逆向过程。词汇是语言的重要建构材料,因此,词汇磨蚀现象成为语言磨蚀领域的研究重点。二语习得中的词汇磨蚀虽引起了应用语言学界的关注,但相比于其他语言,汉语词汇磨蚀的研究尚处于起步阶段,相关文献十分稀少,且涉及汉语学习者的词汇磨蚀调查尚不多见。鉴于此,笔者从非汉语母语者的角度出发,借鉴前人的实证研究成果,对就读汉语言专业的50名越南学生进行了为期三个月的跟踪研究。本文根据外语词汇磨蚀理论框架中的四项假说（回归假说、倒置假说、阈值假说及提取失败假说）,针对影响越南学生汉语词汇磨蚀的语言因素和非语言因素两个方面设计调查内容并展开研究。研究结果显示:第一,以三个月为受蚀时间,82%受试者的汉语词汇发生了磨蚀,但磨蚀量并不大;第二,磨蚀前的汉语水平和词汇磨蚀程度呈反比,即语言水平越高,汉语词汇磨蚀量就越少。此外,学生的汉语水平达到一定的程度,也就是达到语言学习中的一个临界点后,所掌握的词汇知识就较耐磨蚀;第三,词汇学习顺序影响受试者的汉语词汇磨蚀,越是靠后学习的汉语词汇,越容易遭受磨蚀;第四,汉语词汇的语言学特征和汉语词汇特点对词汇磨蚀起着一定的影响;第五,课外汉语接触频率和词汇学习策略使用情况都与汉语词汇磨蚀呈反比。换言之,经常接触汉语和运用词汇学习策略有助于减少汉语词汇的磨蚀现象;第六,初始汉语水平、课外汉语接触以及词汇学习策略共同影响受试者的汉语词汇磨蚀。本研究的相关结果有助于加深语言磨蚀乃至词汇磨蚀本质的理解,为今后有关汉语磨蚀的研究提供借鉴,且弥补了越南汉语习得动态研究的空缺。除此之外,本研究也对提高汉语词汇教学的有效性和防止词汇磨蚀的出现提供了一些重要启示。
