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.

引用

Journal of Environmental Protection 2019年第10期10卷 1361-1372页

作者： Nguyen Thi Hong Thinh Vu Hoai ha Lan Anh Vo Thi Anh Truong Viet chau trinh Van Giap Tran Minh Tien Isotope Hydrology Laboratory Institute for Nuclear Science and TechnologyHanoiVietnam Soils and Fertilizers Research Institute HanoiVietnam

In this study, the experiments on field were conducted to examine the change in the content of soil organic carbon (SOC), its C-13 stable isotope composition (δ 13C) and some main physical, chemical parameters (soil moisture, pH, soil density, content of humic, fulvic, total N, total P, total K) in alluvial soil of Dan Phuong region—Vietnam at a depth of 0 - 30 cm when we changed the regime from 2 maize -1 rice crop to 2 rice - 1 maize crop per 1 year. In addition to analyzing the main parameters in soil, C content and its δ 13C value in parts of rice and maize (root, stem and leaf) were also analyzed to assess the contribution of plant residues on soil organic carbon content after harvest. The experiment was carried out in 2016-2017 on the field with the traditional farming method of local farmers along with the tropical monsoon weather conditions of the North-Vietnam. The results showed that SOC had positive correlation with total N, total P parameters and negative correlation with δ 13C values of soil samples at two layers (0 - 15 cm and 15 - 30 cm). The average of total dry biomass (stem, stump + roots and leaf parts) per 1 rice and 1 maize crop was 10.64 Mg/ha and 9.09 Mg/ha, respectively. The average of δ 13C value of rice (C3 plant) was -29.78‰ and its value of maize (C4 plant) was -12.61‰. The new plant (rice) contributes to the total soil organic carbon content from 11.31% to 44.14% at the 0 - 15 cm layer and from 6.55% to 11.31% at the 15 - 30 cm layer in one-year experiment period.

Positron Annihilation in Perfect and Defective TiO2Rutile Crystal with Single Particle Wave Function: Slater Type Orbital and Modified Jastrow Functions

引用

World Journal of Nuclear Science and Technology 2014年第1期4卷 33-39页

作者： trinh Hoa Lang chau Van Tao Kieu Tien Dung Le Hoang Chien Faculty of Physics and Engineering Physics University of Science Ho Chi Minh City Vietnam Swinburne University of Technology Melbourne Australia

Positron annihilation in TiO2 rutile crystal is studied by an assumption that a positron binds with valance electrons of a titanium dioxide to form a pseudo TiO2-positron molecule before it annihilates with these electrons. The orbital modification consisting of explicit electron-positron and electron-electron correlation in each electronic orbital is used for the electrons and positron wave functions. By these wave functions, the calculation results of the positron lifetimes in unmitigated and defective TiO2 crystals are about 170 ps, 266 ps and 243 ps, respectively. These results are in good agreement with experimental data of the positron lifetimes in vacancies of TiO2 from 180 ps to 300 ps.

Lithium aluminate (LiAlO2) powder was synthesized by sol-gel with EDTA method. The resultant powders were characterized by X-Ray Diffraction (XRD) and Scanning Electronic Microscopy (SEM) techniques. In addition, several thermoluminescence properties of synthesized LiAlO2 powder were reported. The results from X-ray diffraction (XRD), the powder prepared by sol-gel with EDTA method showed pure γ-phase when it was calcined at >900°C. Scanning electron microscopy (SEM) results show that the size of the lithium aluminate particles depended strongly on calcination temperature. The linearity is observed of synthesized LiAlO2 powder by sol-gel with EDTA with regression coefficient (R2) is 0.9971.

In Australia, perinatal depression affects 15% - 20% of pregnant women. Depression does not go away on its own, getting help at early stages shown to be effective in treating antenatal depression. Aim of this study is to assess and describe the screening of women through the antenatal clinic and measure the outcome of services provided (such as counselling, social assistance) for those at risk of depression, in a general hospital setting in an ethnically diverse part of Sydney, Australia. Data from 193 women were obtained through accessing the psychosocial and screening assessments completed at the antenatal clinic between 2007 and 2008. Data regarding patients’ psychosocial characteristics, referrals and interventions were also gathered from hospital records. Data revealed that 60.4% of women screened scored ≥10 on the Edinburgh Postnatal Depression Scale (EDPS) which is indicative of significant depressive symptomatology. Of these women, 39.4% went on to receive a formal diagnosis. Women who indicated that they had planned their pregnancies (47.2%) were significantly less likely to report having major worries and stressors over the last 12 months (p hat their pregnancies were unplanned. Data showed while screening methods are effective, regrettably a high proportion of women, despite presenting with “at risk” symptomatology levels, do not engage in intervention programs. Further research is required to explore the barriers in accessing both screening and intervention services (particularly in a culturally diverse area such as this), and how services can improve processes and patient participation.

The trees in urban landscapes, independent of whether they are in urban forests or stand alone,can improve environment quality, enhance individual and community well-being, provide a wide range ofservices to individuals and communities, and produce a more healthful and comfortable environment forthe vast majority of the population. Knowledge of the potential significance of trees in urban landscapesis expanding rapidly as research continues to document the important role that urban forests and trees canplay in improving the quality of urban life. The environmental conditions in urban landscapes are, however,very different from the natural conditions that the tree species are adapted to. This poses big challenges tothe urban forestry in its efforts to create healthy and valuable trees in urban landscapes. Only throughimplementing some important measures we can ensure high survival rate of saplings and well-being andlongevity of urban trees.
