Adaptability Zoning for Salty-Tolerant Rice Varieties in Soc Trang Prefecture by Using GIS and Remote Sensing

引用

Journal of Geological Resource and Engineering 2016年第3期4卷 142-150页

作者： Tran thanh Dan Tran Thi Ngoc Trinh vo Quang Minh Huynh Ngoc Van Department of Land Resources College of the Environment and Natural Resources Can Tho University Viet Nam Department of Science and Technology Graduate School of Engineering Nagasaki University Japan Center of Seed and Plant Soc Trang province Viet Nam

Soc Trang is one of coastal provinces in which rice land is relatively low and therefore under annual threat of saline intrusion and other climatic variabilities. It raises an urgent need to identify various rice varieties which are short-duration, highly adaptive to salinity penetration, floods and aluminium poisonous matters, as well as high productivity and quality. The research applies the GIS （Geo-Information System） and RS （Remote Sensing） techniques to accurately evaluate the adaptability of different salinity-tolerant rice varieties. We have used information from FAO （The Food and Agriculture Organization）, Maplnfo and ArcGIS to map different components separately that are overlapped and mixed together to build different maps indicating the adaptability of different rice varieties to salinity in different locations in Soc Trang. We have also identified various factors affecting the productivity of these rice varieties. Then, several salinity-resistent rice varieties have been piloted in different areas to figure out which varieties are most suitable for specific regions.

Determination of fuel burnup distribution of a research reactor based on measurements at subcritical conditions

引用

Nuclear Science and Techniques 2018年第12期29卷 30-38页

作者： Quang Binh Do Hoai-Nam Tran Quang Huy Ngo giang T. T. Phan Ho Chi Minh City University of Technology and Education 1 Vo Van Ngan Thu Duc HCMC Vietnam Institute of Fundamental and Applied Sciences Duy Tan University Ho Chi Minh city Vietnam

This paper presents the determination of the fuel burnup distribution of the Dalat nuclear research reactor(DNRR) using a method of measurements at subcritical conditions. The method is based on the assumption of linear dependence of the reactivity on the burnup of fuel bundles and the measurements at subcritical *** measurements were taken for seven selected fuel bundles in two different measuring sequences. The measured burnup values have also been compared with the calculations for verifying the method and the measurement procedure. The results obtained with the three detectors have a good agreement with each other with a discrepancy less than 1.0%. The errors of the measured burnup values are within 6%. Comparison between the calculated and measured burnup values shows that the discrepancy of the C/E ratio is within 9% compared to unity. The results indicate that the method of measurements at subcritical conditions could be well applied to determine the relative burnup distribution of the DNRR.

Health 2015年第12期7卷 1696-1702页

作者： Huong Le Thi Phuong Le Hong thanh Nguyen Hoang giang Nguyen Thu Xuan Le Thi thanh Chuc Nguyen Thi Kim Nga Thi Thu Vu Institute for Preventive Medicine and Public Health Hanoi Medical University Hanoi Vietnam

Background: During the nutrition transition period which began in the early 1990s in Vietnam, dietary intake had been changed significantly because of changes in lifestyle and living standard. Objectives: This paper aims to describe the trend for food expenditure and the frequency of meat consumption in households in Ba Vi district, Hanoi, Vietnam from 1999 to 2013. Methods: This is a longitudinal study conducted in Ba Vi district, Hanoi. Semi-annual, face-to face interviews were conducted by well-trained interviewers with 11,922 households to collect data of the household’s income, spending for food and meat consumption. Chi-square test for trend was performed to evaluate the changes of food expenditure over the years. P-value under 0.05 was considered statistically significant. Results: There were ten times increase in household’s mean income and five times increase in mean food expenditure from 1999 to 2013. The percentage of household food expenditure per total family expenditure was really high (55% in 2013). The percentage of rice expenditure per total food expenditure decreased dramatically from 59.9% in 1999 to 33.1% in 2013 while spending for other animal-based, high-protein food was an upward trend, particularly meat (10.7% in 1999 to 24.2% in 2013). The percentage of rice expenditure in well-off households was lower than poor households (55% vs. 61.8% in 1999 and 31.4% vs. 36.5% in 2013). However, the percentage of spending for meat in well-off households were much higher than that of poor households (>10%). Conclusion: Our finding indicated that mean income and food expenditure, particularly meat intake, of households had increased dramatically from 1999 to 2013. The increase of meat intake requires reallocation and direction of Vietnam public health funding and strategy.

Landslide susceptibility maps (LSMs) are very crucial for planningpolicies in hazardous areas. However, the accuracy and reliability ofLSMs depend on available data and the selection of suitable *** study is conducted to produce LSMs by combinations of machinelearning methods and weighting techniques for Ha giang province,Vietnam, where has limited data. In study area, we gather 11 landslideconditioning factors and establish a landslide inventory *** the weights of classes (or factors) is very important toprepare data for machine learning methods to generate LSMs. Wefrst use frequency ratio (FR) and analytic hierarchy process (AHP)techniques to generate the weights. Then, random forest (RF), supportvector machine (SVM), logistic regression (LR), and AHP methods arecombined with FR and AHP weights to yield accurate and reliableLSMs. Finally, the performance of these methods is evaluated by fivestatistical metrics, ROC and R-index. The empirical results have shownthat RF is the best method in terms of R-index and the five metrics, *** rate (0.9661), FP rate (0.0), ACC (0.9835), MAE (0.0046), and RMSE(0.0350) for this study area. This study opens the perspective of weightbasedmachine learning methods for landslide susceptibility mapping.

In this study,water-dispersible graphitic carbon nitride(g-C_(3)N_(4))photocatalysts were successively prepared through the chemically oxidative etching of bulk g-C_(3)N_(4) that was polymerized thermally in different calcination atmospheres such as air,CO_(2),and N_(2).The different calcination atmospheres directly influenced the physicochemical and optical properties of both bulk and water-dispersible g-C_(3)N_(4),changing the photocatalytic degradation behavior of methylene blue(MB)and tetracycline hydrochloride(TCHCl)for water-dispersible g-C_(3)N_(4).The bubble-burst process in the thermal polymerization of thiourea produced defective edges containing C=O groups that preferred substituting the C-NHx groups over bulk g-C_(3)N_(4).In the oxygen-free N_(2) atmosphere among the different calcination atmospheres,more C=O functional groups were generated on the defective edges of bulk g-C_(3)N_(4),resulting in the highest N vacancy of the tri-s-triazine *** the successive chemical oxidation,S-or O-containing functional groups were introduced onto water-dispersible g-C_(3)N_(4).The water-dispersible g-C_(3)N_(4) photocatalyst from the oxygen-free N_(2) atmosphere(NTw)contained the most O-and S-functional groups on the g-C_(3)N_(4) ***,NTw exhibited the highest photocatalytic activity in the MB and TC-HCl photodegradation because of its slowest recombination process,which was ascribed to the unique surface properties of NTw such as abundant functional groups on the defective edges and N-deficient property.

Materials Sciences and Applications 2015年第6期6卷 533-538页

作者： Thi giang Le Hong Duc University Thanh Hoa City Vietnam

Molecular Beam Epitaxy (MBE) system equipped with in-situ Reflection High-Energy Electron Diffraction (RHEED) has been used for (Ge, Mn) thin film growth and monitoring the surface morphology and crystal structure of thin films. Based on the observation of changes in RHEED patterns during nanocolumn growth, we used a real-time control approach to realize multilayer structures that consist of two nanocolumn layers separated by a Ge barrier layer. Transmission Electron Microscopy (TEM) has been used to investigate the structural properties of the GeMn nanocolumns and GeMn/Ge nanocolumns bi-layers samples.

本专利介绍的是用于中间包的钢水涡流抑制装置。该中间包由铜包通过浇注管注入钢流的浇注段和上浮段组成。从上浮段流出的无夹杂钢水通过长水口流入连铸结晶器。涡流抑制装置是一个由耐火材料制成的闭合的盒子,盒子上有一顶盖,顶盖上有一个接到浇注管底端的开孔,在盒子的各侧墙上开了许多方孔,使进入盒内的钢水以降低了能量的亚流形式流出盒外。闭合盒子的侧墙及其开孔的设计十分合理,从而使各条亚流都从各自的开孔流出并撞击到中间包的壁上,而且其流动方向基本上是垂直于中间包壁的。这种中间包钢水涡流的抑制装置的重要功能是可以有效地消耗钢流进入中间包的动能和缩短注流在中间包钢水内的穿透深度,因而可防止在浇注段内形成的渣被进入结晶器内的钢流带走。
