Sustainability assessment of Vietnam's electricity planning: Using section 1 of the 2009 hydropower sustainability assessment protocol

The Draft Hydropower Sustainability Assessment Protocol (HSAP) was first introduced in Vietnam at the National Consultant Workshop organized by Vietnam Water Partnership (VNWP) in November 2009. Although the structure of HSAP is relatively complex and new to Vietnam, the participants (from Government agencies, experts, investors, and Vietnamese and international civil society organizations) had the impression that the HSAP has the potential to be a useful tool for participatory assessment of the sustainability of a hydropower project and broader planning. With the assistance of the M-POWER (Mekong Program on Water, Environment and Resilience), a national group of experts in multiple disciplines from government agencies, national organisations and NGOs was mobilized to conduct a rapid sustainability assessment of the energy and hydropower development policy and plan in Vietnam. Section I of the draft HSAP 2009 was used as an assessment tool. The assessment focused on the quality of the process of developing and implementing the strategic development of the electricity sector in general and hydropower development of Vietnam in particular. Even though the rapid assessment framework of HSAP was quite new to the Assessment Team and the assessment subjects are broad, the Team and participants in this trial learned positive and negative lessons that can serve as a basis for future assessment exercises to enable deeper and more comprehensive assessment. The assessment report includes four major parts: 1) Introduction and background, 2) Water and hydropower development in Vietnam; 3) Rapid assessment - process and discussion of results; and 4) Lessons learned from the assessment and recommendations for draft HSAP 2009

Large-scale Vietnamese point-of-interest classification using weak labeling

Point-of-Interests (POIs) represent geographic location by different categories (e.g., touristic places, amenities, or shops) and play a prominent role in several location-based applications. However, the majority of POIs category labels are crowd-sourced by the community, thus often of low quality. In this paper, we introduce the first annotated dataset for the POIs categorical classification task in Vietnamese. A total of 750,000 POIs are collected from WeMap, a Vietnamese digital map. Large-scale hand-labeling is inherently time-consuming and labor-intensive, thus we have proposed a new approach using weak labeling. As a result, our dataset covers 15 categories with 275,000 weak-labeled POIs for training, and 30,000 gold-standard POIs for testing, making it the largest compared to the existing Vietnamese POIs dataset. We empirically conduct POI categorical classification experiments using a strong baseline (BERT-based fine-tuning) on our dataset and find that our approach shows high efficiency and is applicable on a large scale. The proposed baseline gives an F1 score of 90% on the test dataset, and significantly improves the accuracy of WeMap POI data by a margin of 37% (from 56 to 93%)

EVALUATION OF ACUTE AND SUB-ACUTE ORAL TOXICITY OF CLINACANTHUS NUTANS LEAVES EXTRACT IN MICE

Objective: This study aimed to evaluate acute and sub-acute oral toxicity of ethanol extract of Clinacanthus nutans leaves in Swiss mice. Methods: Acute oral toxicity study was performed as per OECD-423 guidelines. Sub-acute oral toxicity study was performed as per OECD-407 guidelines. The extract was dissolved in 10% dimethyl sulfoxide and administered orally, while the control group received only the vehicle. Results: The acute oral toxicity test on mice showed that this extract was well tolerated up to LD50 5000 mg/kg body weight/day oral dosage level and non-toxic to mice under the present experimental conditions. The sub-acute toxicity study was carried out on mice with the oral dosage of the extract from 100 mg/kg–500 mg/kg body weight/day and 5000 mg/kg body weight/day for 28 d. The results showed that this extract did not induce death or adverse effects in activity, feed consumption or body weight gain. There were not significant changes in heamotological and biochemical parameters between control and experiment groups. Conclusion: Thus, Clinacanthus nutans leaf has a very low toxicity value

Constitutive models of concrete at elevated temperatures: Studying the effect of temperature gradients

The outbreak of fire can have serious consequences in the structural performance of a load-bearing concrete structure. To assure adequate fire performance, detailed knowledge of fundamental mechanical properties of concrete at elevated temperatures is crucial. This paper first highlights limitations of existing knowledge regarding the mechanical response of concrete at elevated temperatures, including the inconsistent thermal boundary conditions and intentionally-minimised temperature gradients in "standardized" conventional concrete material testing. Accordingly, it is argued that the effect of temperature gradients within concrete on its fire performance has not been extensively or directly addressed.On this basis, the paper outlines key features of an ongoing research programme at The University of Queensland aimed at studying the performance of concrete in fire using a novel medium-scale testing method. By heating using radiant panels, well-defined and consistently-controlled heat flux boundary conditions on concrete cylinders (phi 100mm x 200mm) have been achieved. The repeatability, consistency, and uniformity of thermal boundary conditions are demonstrated using measurements of heat flux, temperature profile, and compressive strength.Analysis of initial obtained data shows that the incident heat fluxes, and thus the associated temperature gradients, have potentially significant effects on concrete properties at elevated temperatures. Further research is thus ongoing to quantify such effects and also to develop models for their inclusion into effective performance-based fire design and analysis of concrete structures

g-INFO portal: a solution to monitor Influenza A on the Grid for non-grid users

International audienceIn this paper, we introduce a portal for monitoring Influenza A on a grid-based system. Influenza A keeps on being a major threat to public health worldwide; especially if one virus can mutate itself so that it acquires the capacity for human to human transmission of H1N1 as well as the high death rate of H5N1. The existing g-INFO (Grid-based Information Network for Flu Observation) project provides a complete system for monitoring flu virus on the Grid. We present here a portal that operates on top of the g-INFO system as a solution for non-grid users to utilize grid services for analyzing molecular biology data of Influenza A

The Synthesis and Photoluminescence of 3C-SiC Nanorods

The 3C-SiC nanorods were grown by using carbothermal reduction of SiO$_{2}$ without any catalyst. The intensive broad photoluminescence peak around 480-500 nm was observed at room temperature. The 3C-SiC nanorods with green -- blue emitting light may have great application in display devices and light emitting diodes

Depression and Anxiety as Key Factors Associated With Quality of Life Among Lung Cancer Patients in Hai Phong, Vietnam

Background: Cancer is a leading cause of death. People living with cancer experience a variety of symptoms that might profoundly affect their quality of life (QoL).Objective: The study aims to identify factors associated with the QoL of patients with lung cancer at the oncology department of Viet Tiep Hospital, Hai Phong city, Vietnam in 2018.Methods: A cross-sectional study was conducted to collect data from lung cancer inpatients in Hai Phong city, Vietnam. The EQ-5D-5L and the EuroQol (EQ)-visual analogue scale (EQ VAS) were used to assess health-related quality of life (QoL). A multivariable regression analysis was performed on the EQ-5D utility score and the EQ VAS score as dependent variables, and socioeconomic, social support, and psychological factors as potential predictors.Results: A total of 125 lung cancer patients were enrolled in this study. The highest proportion of respondents reporting any problems was in anxiety/depression (92.8%), pain/discomfort (81.2%), usual activities (75.2%), and mobility (60%) dimensions, while the lowest percentage was in self-care dimension (40.8%). The multivariate analyses showed that a low QoL score was significantly associated with depression, incapacity to pay, low response to treatment, and presence of side effects.Conclusion: QoL of lung cancer patients is associated with anxiety/depression and other factors that can be modified by specific interventions. It is therefore possible to take care of psychological aspects to improve the QoL of Vietnamese people suffering from this condition
