The Role of Market Insights in Shaping Sustainable Mobility in Fast Developing Countries: The Case of Vietnam
Full text linkIndividual mobility represents one of the main contributors of air quality degradation in
urban areas, with detrimental social and environmental impacts as well as economic loss. Mobility
policies hence represent a key public instrument to curb congestion, pollution and health-related
problems. In order to be effective, they need to rely on an adequate knowledge of demand, in terms of
commuters’ attitudes, habit strength and perceived priorities. While most studies on the determinants
of modal choice are rooted in Western countries or in developed economies little evidence is available
for fast-developing countries, whose urban areas suffer from severe congestion and bad air quality.
We test a comprehensive model to predict mobility behaviors in Vietnam, by means of an empirical
investigation, with data from 898 participants (N = 898) collected via an online self-administered
questionnaire. We discuss the implications for policy of the research findings, which provide an
informational background representing a necessary prerequisite for the implementation of sound policies for the shift to more sustainable paradigms
Nutritional and functional properties of protein hydrolysate from Tra fish by-products
No full text8 p.The nutritional and functional properties, molecular weight distribution of protein hydrolysate from Tra fish by-products were studied. The protein hydrolysate was produced by enzymatic hydrolysis of Tra fish by-products with Protamex 0,5% at the temperature of 50oC in 6 h. The study results showed that the Tra fish by-products protein hydrolysate had a moisture content of 6,7%, protein content of 65.8%, lipid content of 1,6% and ash content of 9,5 %. The protein hydrolysate had a total amino acid content of 52,81 g/100g of protein and essential amino acid content of 16,25 g/100g of protein. The ratio of essential amino acids to total amino acids was 30,76%. The protein hydrolysate was rich in glycine, glutamic, proline, alanine, aspartic and leucine. The most of peptides (68,25%) in Tra fish by-products protein hydrolysate had a molecular weight between 360 Da and 2.500 Da. The protein hydrolysate had solubility in the range of 90,3% - 98,2%. The solubility of protein hydrolysate was the lowest value at pH 4 and the highest value at pH 10. The foaming capacity of protein hydrolysate ranged from 19,5% to 27,8%. The emulsifying capacity of protein hydrolysate was 12,8 – 17,3 mL/g. The protein hydrolysate of Tra fish by-productspossesses high nutritional value and good functional properties. The study results suggested that the protein hydrolysate from Tra fish by-products could be used as a promising food ingredient and protein source in food systems

Effects of temperature and salinity on growth performance in cultured Tra catfish (Pangasianodon hypophthalmus) in Vietnam
No full textThis project is a step towards assessing the effects of climate change on the tra catfish industry in Vietnam. The methods were designed to evaluate possible effects of salinity and temperature increase and their interaction on fish physiological parameters, growth performance, survival and the expression of stress related genes. Results indicated that tra had higher overall performance at 35oC with 6ppt salinity and therefore should cope with moderate predicted outcomes of climate change for the region. The experiments were mostly conducted in the Mekong Delta, Vietnam - the centre of the tra catfish industry with the cooperation of Can Tho University – Can Tho City – Vietnam

Comment on "Soil salinity assessment by using near-infrared channel and Vegetation Soil Salinity Index derived from Landsat 8 OLI data: a case study in the Tra Vinh Province, Mekong Delta, Vietnam" by Kim-Anh Nguyen, Yuei-An Liou, Ha-Phuong Tran, Phi-Phung Hoang and Thanh-Hung Nguyen
Full text linkNguyen et al. (Prog Earth Planet Sci 7:1, 2020. ) suggest that Landsat 8 OLI can be used to map and monitor soil salinity in the coastal zone of the Mekong River Delta. The authors use empirical correlations between the near-infrared (NIR) band, or vegetation indexes containing the NIR band, and soil salinity. We show that within the coastal portion of the Mekong Delta, extensively ponded due to widespread shrimp farming, about 90% of Landsat 8 pixels are fully or partially covered by water. We then find that, due to strong NIR radiation absorption, NIR reflectance from ponded pixels decreases linearly with increasing water percentage cover, while no significant correlation is found between reflectance and soil salinity. Through detailed new analyses, we conclude that NIR reflectance attenuation cannot be ascribed to vegetation stress caused by soil salinity, but rather to the presence of water ponds. We also show that a similar behavior exists in ponded freshwater inland areas, confirming that the NIR absorption exerted by water is independent of salinity
