The relation between fault movement potential and seismic activity of major faults in Northwestern Vietnam

Introduction: The economy of Vietnam, a highly populated tropical country with a per capita gross domestic product of $ 8 000, is growing rapidly, but there are few recent studies of general scope about its scientific productivity and how it compares with other tropical countries. Objective: To identify trends in Vietnamese science and compare them with trends in other tropical countries. Methods: We extracted data about scientific papers, in all disciplines that had Vietnam as country in the Science Citation Index Expanded for the period 1991 to 2018, focusing on type of publication, language, subject, authorship, collaboration, , and citations. Results: Vietnam publishes more document types than other tropical countries, and those in this particular database are mostly in English, albeit most Vietnamese science is published in Vietnamese and not covered by the index. The primary categories were multidisciplinary materials science, mathematics, and applied mathematics. Most collaboration was done with the USA, Japan, South Korea, and France. A large number of articles were published by the Vietnam Academy of Science and Technology, and the most frequent foreign collaboration was with University of Oxford. Conclusion: the tropical countries of Latin America, Africa, and Asia studied in our project have some similarities but also crucial differences. Science is developing rapidly in Vietnam and the production of articles in Vietnamese, which represent the vast majority of research in the country but is not included in this database, should also be studied.

Lately, many important documents on strategic orientation, systemizes and policies for science and technology development have been issued. The management of science and technology activities has been constantly changing and adapting; shown by more favorable legal environment; ensuring the rights and interests of organizations and individuals involved in science and technology activities; ensuring the decentralization, level of responsibilities among each participants in the implementation of science and technology activities. Due to the change in policy and practical development needs, the management of science and technology tasks at public non-business units under the Vietnam Academy of Science and Technology has made changes in accordance with the Law on Science and Technology in 2013 and Decree No. 60/2021/ND-CP dated June 21, 2021 of the Government stipulating the mechanism of financial autonomy for public non-business units. By understanding of the current situation and affecting factors of the management of science and technology activities at public non-business units, solutions are proposed to complete the management of such activities in accordance with the functions and tasks of public non-business units under the Vietnam Academy of Science and Technology will contribute to the improvement of the management of science and technology tasks of the country in general, and of the Vietnam Academy of Science and Technology in particular.

This paper reports the results of the third Russian–Vietnamese expedition (V.I. Il'ichev Pacific Oceanological Institute, Far East Branch, Russian Academy of Sciences and the Institute of Marine Geology and Geophysics, Vietnam Academy of Science and Technology) in the Gulf of Tonkin, South China Sea (April 2016). The studies revealed new specific features of the distribution and origin of gasgeochemical fields in sediments within the rift zone of the Red River along a 150-km profile. Four zones with high-amplitude anomalies of hydrocarbon gases, helium, hydrogen, carbon dioxide, and carbon monoxide were revealed. The distribution of the anomalies reflects the tectonic structure of the area and points to the presence of several lithospheric sources of gases including gases of deep origin. The studies were carried out within the scope of the Joint Vietnamese–Russian Laboratory for Marine Geoscience (V.I. Il'ichev Pacific Oceanological Institute, Far East Branch, Russian Academy of Sciences and the Institute of Marine Geology and Geophysics, Vietnam Academy of Science and Technology).

This paper reports the results of the third Russian–Vietnamese expedition (POI FEB RAS and the Institute of Marine Geology and Geophysics, Vietnam Academy of Science and Technology) in the Gulf of Tonkin, South China Sea (April 2016) and field work outcomes from 2016-2017. The studies revealed new specific features of the distribution and origin of gas-geochemical fields in sediments within the rift zone of the Red River along a 150-km profile. Four zones with high amplitude anomalies of hydrocarbon gases, helium, hydrogen, carbon dioxide, and carbon monoxide were revealed. The distribution of the anomalies reflects the tectonic structure of the area and points to the presence of several lithospheric sources of gases including gases of deep origin. The studies were carried out within the scope of the Joint Vietnamese–Russian Laboratory for Marine Geosciences (POI FEB RAS and the Institute of Marine Geology and Geophysics, Vietnam Academy of Science and Technology). The article is dedicated to the year of friendship between Russia and Vietnam.

BackgroundCham Islands (Cu Lao Cham) is a group of 8 small islands in the Quang Nam province, Central Vietnam. There is only one study that mentioned the diversity of marine molluscs in this area. However, the data on species composition have not been digitised and not stored or shared for other purposes. Our paper aims to share the checklist of marine mollusc species (Bivalvia and Gastropoda) species that we collected from the littoral zone of Cham Islands in May 2017. This is the first digitised and online data of marine molluscs in Vietnam. It is very important for researchers in various fields such as the structure and function of ecology and biodiversity monitoring.New informationThis study provides a checklist of the marine bivalves and snails in the Cham Islands of Vietnam. Moreover, this first widely shared data of biodiversity in Vietnam can trigger biodiversity data papers in this data-poor country.The data of this study will be important inputs for better understanding biodiversity on the Cham Islands and Vietnam as well as for forming the basis for monitoring, exploitation and conservation of biodiversity in this area.In total, 145 taxa were recorded, 46 bivalve taxa and 99 snail taxa, from which 128 were identified to the species level and 17 were identified to the genus level. There are 116 new species records for the Cham Islands.The specimens are currently deposited in the Institute of Ecology and Biological Resources (IEBR), Vietnam Academy of Science and Technology (VAST).

The paper presented two X-ray fluorescence analysis methods applicable to element content analysis in mixed fertilizers. The applied addition method determined the content of each ingredient in the fertilizer. The fundamental parameter method was applied for quick analysis, and at the same time, the content of ingredients on the fertilizer production line. X-ray fluorescence analysis methods and equipment have been researched and developed by the Institute of Materials Science - Vietnam Academy of Science and Technology and put into the gold and silver field for more than 30 years. The machines fabricated after 2014 applied TCVN 7055:2014, the 2nd edition "gold and gold alloys – Determination of gold content by X-ray fluorescence method". The national gold standard sample set, managed by the Vietnam Metrology Institute, was used to calibrate the machine, which has standard association with NIST (USA) and Krastsvetmet (Russia). Up to now, there are nearly 100 machines operating in more than twenty provinces and cities across the country, used to check the content of alloying components in gold jewelry processing, production and trading. The aim of new research and development in the field of fertilizers, in the coming time, is to transfer equipment and analysis methods to fertilizer production and trading enterprises.

A study on development of a system for bioclimatic classification criteria and construction of a bioclimatic map of Tay Nguyen region at scale of 1/250,000 was conducted, based on statistical analysis of bioclimatic characteristics of Tay Nguyen, comparing with those of other regions of Vietnam. The system of classification criteria was developed based on 4 factors, namely: mean annual temperature (TN), total annual rainfall (RN), length of cold season (N) and length of dry season length (n). The thermal-humid indicators, featuring seasonal constraints (for tropical plants) as well as the thresholds for their division, were selected based on the ecological characteristics of vegetation and their role for the formulation, structure, appearance of the natural vegetation types of Tay Nguyen region. Results showed bioclimatic resources of Tay Nguyen territory is rich and diverse reflecting in 23 different bioclimatic units of a total of 57 separate polygons. That partly explains the diversity of vegetation types ofTay Nguyen. Study of bioclimatic classification has both a scientific and practical significance. Bioclimatic classification provides an important information for mapping ecological landscape of Tay Nguyen; A bioclimatic resource assessment of a specific territory is a necessary scientific basis for proposing the development orientation of economic sectors and establishment of sample sustainable economic models in Tay Nguyen territory.References Lam Cong Dinh, 1992: Bioclimatic applications in forestry in Vietnam.

One new species Belisanadenticulatasp. n. (♂) is reported from northern Vietnam based on material collected by fogging the forest canopy. This species resembles Belisanascharffi Huber, 2005, but can be distinguished by relatively long distance between proximal parts of proximo-lateral apophysis and distal apophysis on male chelicerae, by presence of a nearly saddle-shaped prolateral sclerite on procursus, and by different shape of retrolateral membranous flap on procursus. Type specimens are deposited in the Vietnam Academy of Science and Technology in Hanoi.

Wastewater is commonly used in agriculture and aquaculture in developing countries but also in developed countries due to the growing water scarcity. In Vietnam, the use wastewater and excreta in agriculture has a long tradition. While this practice has clear advantages (fertiliser, economic impacts etc.), it harbours potential risks for health and environment. The aim of the thesis was to understand the health and environmental risks related to wastewater and excreta reuse in an agricultural community in Northern Vietnam, with a focus on intestinal parasitic infections and diarrhoeal diseases and nutrients flow. This work is to optimizing the benefit of wastewater and excreta reuse in agriculture in from health and environmental perspective, which allows proposing potential interventions for health and environmental improvement. Methods In the study area - 2 communes of Hoang Tay and Nhat Tan in Hanam province, Northern Vietnam - wastewater (i.e. Nhue River and local pond), human and animal excreta are commonly used as water irrigation and fertilisers: (i) Cross-sectional, cohort and nested case-control studies were conducted to assess the relative importance of exposure to wastewater and excreta for parasitic infection and diarrhoeal episodes. Exposure data were obtained from household and individual interviews. Stool examinations were used to assess infection status. (ii) Quantitative microbial risk assessment (QMRA) of Escherichia coli, Giardia lamblia and Cryptosporidium parvum infection due to the exposure to wastewater and excreta was conducted using multi-trial Monte Carlo simulations to estimate diarrhoeal risks. (iii) Material flow analysis (MFA) was used to analyse nitrogen (N) and phosphorus (P) flows in the environmental sanitation and agricultural systems. Results Helminth infections were prevalent (e.g. Ascaris lumbricoides 24%, Trichuris trichiura 40%, and any helminth infections 47%). Risk of infection increased for people having direct contact with Nhue River water (OR = 2.1, 95% CI 1.4-3.2), and using human excreta as fertiliser (OR = 1.5, 95% CI 1.0-2.3). Tap water use in household was a protective factor against T. trichiura infection (OR = 0.6, 95% CI 0.4-0.9). Entamoeba histolytica infection was not associated with contact with Nhue River and pond water, and human and animal excreta, but with close contact with domestic animals (OR = 5.9, 95% CI 1.9-18.9), never or rarely washed hands with soap (OR = 3.4, 95% CI 1.1-10.0) and average socioeconomic ststus (OR = 4.3, 95% CI 1.3-14.0). Diarrhoeal incidence in adults was 0.28 episodes per person per year (pppy). The direct contact with water from the Nhue River (OR = 2.4, 95% CI 1.2-4.7) and local ponds (OR = 2.3, 95% CI 1.3-4.3), handling practices of human excreta (OR = 5.4, 95% CI 1.4-21.1), and animal excreta (OR = 3.3, 95% CI 1.8-6.0) as fertilisers were important risk factors for diarrhoeal diseases. Furthermore, inadequate use of protective measures (OR = 6.9, 95% CI 3.5-13.9), close contact with people having diarrhoea (OR = 3.7, 95% CI 1.4-10.3), never or rarely washed hands with soap (OR = 3.3, 95% CI 1.8-6.3), eating raw vegetables the day before (OR = 2.4, 95% CI 1.2-4-6), and rainwater use in household for drinking (OR = 5.4, 95% CI 2.4-12.1) were also associated with increased the risks of diarrhoeal diseases. QMRA revealed that the most hazardous exposures included direct contact with Nhue River, local pond and field water, household sewage, and composted excreta. The annual infection risks due to exposure to wastewater exceeded the WHO reference level (10-4, i.e. ? 1 infection per 10,000 individuals), e.g. in scenario of growing rice, G. lamblia caused an infection risk of 0.75, C. parvum (0.39), and E. coli (0.96). The annual diarrhoeal risks were much greater than the WHO threshold values of 10-3 (i.e. 0.001 pppy), e.g. due to G. lamblia (0.50), C. parvum (0.15) and DEC (0.24) in scenario of growing rice. MFA simulations highlighted that the sanitation system is an important source of nutrients entering the surface water. Every year, 109 tonnes of N and 35 tonnes of P (75% N and 65% P from on-site sanitation system effluents) are discharged into the drainage system; and 118 tonnes of N and 25 tonnes of P released into surface water. Furthermore, simulations revealed that if nutrient management is not improved, levels of nutrients due to wastewater, faecal sludge, and organic solid waste will double until 2020. Conclusions In the agricultural settings, where wastewater and excreta are commonly used, important health and environmental impacts were documented. For mitigation purposes, personal hygiene practices and safe water and food consumption must be further addressed. Adequate on-site sanitation system technologies are warranted to assure waste treament and reduce nutrients discharge to the environment. Further investments in this direction are warranted to improve benefit-risk ratio for the agricultural community and increase sustainability of this agricultural system.

The magnitude of storm surge depends on many factors: The intensity, direction, and speed of the storm, coastal topography, tidal height, etc. This paper presents the study results of the influence of tide on storm surge in Do Son coatal zone, Hai Phong City, based on the calculating results of storm surge in cases tidal and non-tidal storms landed into this coastal area from 1951 to 2020. The numerical model is used to calculate storm surge in this study is the TSIM11 model. This model can calculate wave, tide and storm surge and it was constructed by the Institute of Mechanics, Vietnam Academy of Science and Technology. The numerical model has been calibrated and validated using measurement data from stations in the study area.
