Stability of twin circular tunnels in cohesive-frictional soil using the node-based smoothed finite element method (NS-FEM)

This paper presents an upper bound limit analysis procedure using the node-based smoothed finite element method (NS-FEM) and second order cone programming (SOCP) to evaluate the stability of twin circular tunnels in cohesive-frictional soils subjected to surcharge loading. At first stage, kinematically admissible displacement fields of the tunnel problems are approximated by NS-FEM using triangular elements (NS-FEM-T3). Next, commercial software Mosek is employed to deal with the optimization problems, which are formulated as second order cone. Collapse loads as well as failure mechanisms of plane strain tunnels are obtained directly by solving the optimization problems. For twin circular tunnels, the distance between centers of two parallel tunnels is the major parameter used to determine the stability. In this study, the effects of mechanical soil properties and the ratio of tunnel diameter and the depth to the tunnel stability are investigated. Numerical results are verified with those available to demonstrate the accuracy of the proposed method

Hai Hau - Nghia Hung are two coastal districts in the Southeast of Nam Dinh province with total area of 35,652.29 km2. Located in the middle between the Southern provinces of the Red river delta and the North Central provinces, Hai Hau and Nghia Hung are about 100 km from Hanoi along National Route 1A and 80 km from Hai Phong, in an area directly affected by the Hanoi - Hai Phong - Quang Ninh growth triangle. The two districts have an approximately 47 km coastline accounting for over 65% of the coastline of the province. Along the coastline there are four rivers: Red river, So river, Ninh Co river and Day river emptying into the sea through the estuaries: Ba Lat, Ha Lan, Ninh Co and Day, which facilitate the development in industry, agriculture, sea ports, trade, tourism... This is also a region with high-speed economic development and a series of plannings. Thus, a number of conflicts in exploiting and using natural resources and environmental protection have been raised, leading to destroyed sceneries, lost ecological balance, and becoming an anxious problem. This paper presents experimental results in defining the conflicts and priorities between sectors and economic fields in integrated coastal space planning of Hai Hau - Nghia Hung districts to select the economic sectors that have the most potential and advantages. Therefore, it will be appropriate in space usage in exploiting and using natural resources and environmental protection, which will provide the basis for the development of a sustainable marine economy.Hải Hậu - Nghĩa Hưng là huyện ven biển nằm ở phía Đông Nam của tỉnh Nam Định có tổng diện tích tự nhiên 35.652,29km2; Nằm ở vị trí trung chuyển giữa các tỉnh phía Nam đồng bằng sông Hồng với các tỉnh Bắc Trung bộ và trong vùng ảnh hưởng trực tiếp của tam giác tăng trưởng Hà Nội-Hải Phòng-Quảng Ninh, Hải Hậu - Nghĩa Hưng chỉ cách Hà Nội theo quốc lộ 1A gần 100 km và cách Hải Phòng trên 80 km; với đường bờ biển dài khoảng 47km chiếm trên 65% chiều dài bờ biển toàn tỉnh; dọc chiều dài đường biển có 4 con sông: Sông Hồng, sông Sò, sông Ninh Cơ và sông Đáy đổ ra biển qua các cửa sông: Ba Lạt, Hà Lạn, Ninh Cơ và cửa Đáy thuận lợi cho phát triển công nghiệp, nông nghiệp, cảng biển, thương mại, du lịch,….đây cũng là khu vực có tốc độ phát triển kinh tế nhanh với hàng loạt quy hoạch nên khu vực này đang nảy sinh các xung đột gây nên những mâu thuẫu trong khai thác sử dụng tài nguyên thiên nhiên và bảo vệ môi trường dẫn đến cảnh quan bị phá vỡ, cân bằng sinh thái bị mất đi và đang trở thành vấn đề đáng quan ngại.

FACTORS INFLUENCING VIETNAMESE STUDENTS’ CHOICES TO ATTAIN ENGLISH PROFICIENCY STANDARDS IN A UNIVERSITY IN VIETNAM

In the current era of globalization, English is considered a necessary skill for education and work and a criterion for evaluation in recruitment and graduation assessments in many places in Vietnam. According to the project entitled "Teaching and Learning Foreign Languages in the National Education System Phase 2008 - 2020", non-English majored university students must achieve a minimum of Level 3 according to the 6-level Foreign Language Proficiency Framework used in Vietnam. Several universities have diversified their ways to meet these standards to facilitate students in meeting the English language outcomes, allowing students more opportunities to choose ways that are suitable for them. However, this also indicates that various influencing factors will impact students' selection of ways to meet these standards. This research explores the primary ways students choose to fulfill English language standards as stipulated and analyzes the factors influencing the choices of non-English major students in universities in Vietnam.  Article visualizations

Studies on phytoplankton pigments: chlorophyll, total carotenoids and degradation products in Vietnamese waters

Distribution of phytoplankton pigments was investigated in the relation to Chlorophyll a (Chl-a) and light intensity in Vietnamese waters located at longitude 102E - 112W, latitute 23N - 7N. Over 200 samples collected at 58 stations were analyzed for pigments (Chlorophyll a, b, c and carotenoids) and degradation products (Phaeophytill). Chlorophyll a was measured by fluorescence. Results show that average values in the seawater were 0.18 ± 0.04 mg.m-3 for Chl-a; 0.05 ± 0.01 mg.m-3 for Chl-b; 0.062 mg.m-3 for Phaeophytill. Higher value of Chl-a occurred at the thermocline but maxima were found at 75 or 50m depths. Average value of Carotenoids concentration was very low about 0.052 ± 0.12 mg.m-3. The report used a model for the relationship between Chlorophyll a content and light intensity to estimate the primary production. Average value of primary production was about 9.04 mgC.m3.day-1 at the surface and 2.63 mgC.m3.day-1 at the bottom. The relationship between Chlorophyll and some environmental parameters such as temperature, salinity was examined. The effects of thermocline and halocline to the primary production were analyzed

Effects of yeast extract and methyl jasmonate on the enhancement of solasodine biosynthesis in cell cultures of Solanum hainanense Hance

In this work, the effects of the elicitors methyl jasmonate (MeJA) and yeast extract (YE) on the growth and solasodine production of Solanum hainanense cells were investigated. The results showed that various concentrations of MeJA (50-250 µM) and YE (1-4 g/L) have different eliciting influences. The increase of solasodine content induced by the elicitation of 3 g/L of YE and 50 µM of MeJA at the beginning of cell culture was about 1.9- and 1.3-fold, respectively, as compared with that of the non-elicitated cells. In general, YE (biotic elicitor) was more effective in enhancing solasodine production than MeJA (abiotic elicitor)
