Opis:
Global climate change and increasing agricultural activity are the main causes of biotic and abiotic stresses, which negatively affect the plant growth and crop yields. The plant root system is the first organ for sensing the soil moisture limitation; therefore root growth under elevated water deficit is an important indicator for plant’s drought tolerance. Although the previous studies focused on the morphological traits of Napier grasses under water stresses, the root growth changes due to drought levels remain largely unclear. In order to evaluate variation in root performance to respond to drought stress, four cultivars named "Cỏ voi thuần" (CVT), King grass, Packchong, and VA06 were grown for 10 days under drought conditions under polyethylene glycol 6000 (PEG6000): 0% PEG6000 as control, 5% PEG6000, 10% PEG6000, 15% PEG6000 and 20% PEG6000. As compared to control, the root growth of all cultivars was reduced under drought treatments; however, significant variation in the root development response to drought levels was found. Among Napier cultivars, "Cỏ voi thuần" expressed drought-tolerant genotypes. The information on the root length, diameter, surface area and volume of the cultivars reveals interesting guidelines for further studies to explore the mechanisms behind root adaptation of Napier grasses to drought.

Opis:
The sacha inchi seeds (Plukenetia Volubilis L.), collected from different ecological regions of Vietnam (the Northern Mountainous region, the North Central region, and Central Highlands Area), were sown in the spring crop (March 2020) in Gia Lam district, Hanoi city, Vietnam. The variety S18 was copyrighted by Ministry of Agriculture and Rural Developmentof Vietnam in 2019 as a special medicinal plant variety. During the period of 26 months after planting, the agronomical parameters, growth and development characteristics (leaf form, number of inflorescences per branches, number of female flowers per inflorescences, etc.), pests and diseases, yields and yield components (number of seeds per fruit, seed weight, seed grain, etc.), ratio of kernel per seed and ratio of oil per seed were evaluated. The evaluation results show that the collected sacha inchi lines have a time from sowing to flowering and fruiting of 108–125 days, a fruiting to ripening of 123–125 days, and a time from sowing to harvesting the first batch of 244–250 days. The annual harvest is carried out at two main times: May–June and November–January. The actual yield of the first two periods is high (2.66–3.07 tons per hectare), and the highest yield is collected in the Northern Mountainous area is 3.07 tons per hectare (in Tuyen Quang province), while and 3.01 tons per hectare are collected in the North Central region (in Thanh Hoa province). In the nursery, root rot caused 2.1–5.3% deaths and green wilt caused 3.1–4.8% deaths of seedlings. In the planting garden, fruit borers, stem borers, cavity worms and red spiders were discovered, causing more serious damage than other types (from 5 to over 50%). The results of evaluation of growth, development, yield components and yield showed that the sacha inchi lines collected in the North Central region (in Thanh Hoa province) and the Northern Mountainous region (in Tuyen Quang province) is the best.

Opis:
The benefit from integrating the information from multi-source was confirmed in the research of hydrologic processes in river basins. However, the use of satellite-based rainfall products in hydrologic stream flow modeling has been limited because of the perceived uncertainty associated with such data. In this study the authors presented the simulated streamflow from a SWAT model driven by merging rainfall between satellite and gauge-observed rainfall for the Lam River Basin. The results demonstrate the usefulness of merging rainfall data for stream flow modelling at a monthly time step.

The belief of ancestor worship is one of the ancient traditions of the Vietnamese which is present in almost every activity of ethnic culture. Through time, ancestor worship has still a lasting vitality in the Vietnamese mind and is respected by people although the current market economy has had an impact on this belief. Thus, we find the core values of the ancestor worship tradition in the family of Vietnam today that are still conserved by each person and each family.
Wiara w kult przodków to jedna ze starożytnych tradycji wietnamskich, wciąż obecna w niemal w każdym działaniu kultury etnicznej. Mimo upływu czasu kult przodków wciąż żyje w wietnamskich umysłach i jest przez ludzi respektowany, chociaż obecna gospodarka rynkowa miała na niego wpływ. Odnajdujemy zatem w wietnamskich rodach podstawowe wartości tradycji czczenia przodków, które są wciąż chronione przez każdą osobę i każdą rodzinę.

Opis:
In surface mining operations, the operating costs of truck-shovel system constitutes 50-60% of the total. Only a little save in the operation costs in this system will bring large profit for the mines. Due to many investment periods, the capacity of both trucks and shovels in Cao Son surface coal mine is different. This leads to the low efficiency and the difficulty in dispatching strategy for the mine. This paper presents the current situation and selection of advanced dispatching strategy for increasing the efficiency trucks and shovels at this surface coal mine. The results show the detailed match factor reflects the state of each team of loader and trucks and should be use as the indicator for dispatching decision for the heterogeneous truck and shovel fleet at Cao Son surface coal mine.

Opis:
During the period from 8th Century to early decades of the 14th Century, Dai Viet was in the course of prosperous development with reigns of Tran Thai Tong (ruled from 1226-1258), Tran Thanh Tong (1258-1278), Tran Nhan Tong (1278-1293), Tran Anh Tong (1293-1314), Tran Minh Tong (1914-1329), and Trang Hien Ton (1329-1341). We can say that this is time of prosperity and advance of Tran Dynasty. The Tran Kings’ piety upon Buddhism had a great impact on thought and government policies, especially the spirit of equality and humanity. Kings of Tran express a great care on life of the people, try to relieve their toils, reduce their duties, help the poor, and enhance the social security.116 From Tran Du Tong onwards, all was not as before anymore. Research on social security by Buddhism in Tran dynasty can be presented in many aspects, but this article just focuses on clarifying the social security through Buddhism’s care on material and spiritual life of the people.
W okresie od VIII wieku do wczesnych dekad XIV wieku - za czasów panowania: Tran Thai Tong (rządził od 1226-1258), Tran Thanh Tong (1258-1278), Tran Nhan Tong (1278-1293), Tran Anh Tong (1293-1314), Tran Minh Tong (1914-1329), i Trang Hien Ton (1329-1341) - Dai Viet był w na drodze rozwoju. Można powiedzieć, że jest to czas prosperity i postępu dynastii Tran. Pobożność królów Tranu wobec buddyzmu miała wielki wpływ na myślenie i politykę rządu, zwłaszcza na ducha równości i człowieczeństwa. Królowie dynastii Tran wyrażają wielką troskę o życie ludzi, starają się ulżyć im w trudach, zmniejszają ich obowiązki, pomagają biednym i zwiększają bezpieczeństwo społeczne. Od czasów Tran Du Tong, wszystko nie było już takie jak dawniej. Badania nad zabezpieczeniem społecznym przez Buddyzm w dynastii Tran można przedstawić w wielu aspektach, niniejszy artykuł koncentruje się jednak tylko na wyjaśnieniu zabezpieczenia społecznego poprzez opiekę Buddyzmu nad materialnym i duchowym życiem ludzi.

As an important task of the country's socio-economic development, protecting the rights of female workers in employment and income is concerned and implemented by international organizations and all countries in the world. The COVID-19 pandemic has been affecting the global economy and hurt the incomes and employment of many female workers. In Vietnam nowadays, there is an increase in the unemployment rate of female workers, gender inequality in employment and income, and the ability to secure their jobs and income. The article analyzes the current regulations and their implementation in the employment and income of Vietnamese female workers in the context of the COVID-19 pandemic. The article also proposes some recommendations on legal provisions related to training backup jobs, arranging and employing female employees, providing income support for female employees during leave due to the COVID-19 epidemic; and policies related to female workers and their employers. These recommendations will improve Vietnam's labor law on female workers’ rights in employment and income and enhance the efficiency of human resource use and socio-economic development.

PLLA-g-LMWNR (LMWNR – low molecular weight natural rubber) was used as a compatibilizer (1–3 wt %) of poly(L-lactic acid)/deproteinized natural rubber (PLLA/DPNR) blend (95/5 w/w). The LMWNR was prepared using TiO2/ZnO (9 : 1 w/w) and H2O2 as co-catalyst. The obtained LMWNR was grafted with 0–12 wt % maleic anhydride (LMWNR-g-MA) and then with PLLA (PLLA-g-LMWNR). A significant improvement in the mechanical properties of the PLLA/DPNR blend was found in the blend that contained 3 wt % PLLA-g-LMWNR. Scanning electron microscopy showed a decrease in the pore diameter from 5.44 to 1.56 μm. The thermal analysis of PLLA/DPNR blends showed that the Tg value of PLLA phase shifted from 63.1 to 61.4°C. These results confirmed that PLLA-g-LMWNR can enhance the compatibility of the PLLA/DPNR blend.

LMWNR otrzymano z DPNR przy użyciu TiO2/ZnO (9 : 1 w/w) i H2O2 jako kokatalizatora, a następnie szczepiono bezwodnikiem maleinowym w ilości 0–12% mas. (LMWNR-g-MA). PLLA-g-LMWNR uzyskano w wyniku szczepienia PLLA z LMWNR-g-MA. Stwierdzono poprawę właściwości mechanicznych mieszaniny PLLA/DPNR zawierającej 3% mas. PLLA-g-LMWNR. Metodą SEM wykazano zmniejszenie średnicy porów z 5,44 do 1,56 μm. Wartość temperatury zeszklenia Tg fazy PLLA mieszaniny PLLA/DPNR, wyznaczona metodą analizy termicznej, zmniejszyła się z 63,1 do 61,4°C. Uzyskane wyniki potwierdziły, że dodatek PLLA-g-LMWNR zwiększa kompatybilność mieszaniny PLLA/DPNR.

In this paper, the formation of the excitonic insulator state in the rare-earth chalcogenides has been investigated through the extended Falicov-Kimball model. Adapting the unrestricted Hartree-Fock approximation, we have derived a set of explicitly self-consistent equations determining expectation values and the excitonic susceptibility in the system. Analyzing the excitonic susceptibility, we have established phase diagrams of the excitonic insulator state depending on the model parameters. The phase structures confirmed the excitonic insulator state is found at low temperature and between two critical values of the Coulomb interaction. The effect of the external pressure on the formation of the excitonic insulator state is also shown.

Opis:
The increasing depth of extraction and the degree of mechanization leading to the risk of workers working in poor microclimate conditions has become one of the major safety issues in coal mines. During the survey of the current microclimate in Mongduong coal mine, it showed that the temperature of the mechanized longwall exceeded the permissible regulations (t°≤ 30°C), the air humidity is about 95–100%. The reason for the increase of air temperature in longwall is due to geothermal, heat radiated from the longwall equipment and the inlet wind high temperature. To improve the thermal environment in the mechanized longwall area, Vietnam's coal mines open use ventilation, but the efficiency is not high. Therefore, the paper evaluated the influence of airflow on the temperature of the longwall, 7 models with different air flow velocities and 3 models with inlet air temperature have been created in ICM-CFD and simulated by Ansys CFX software. The environment temperature of each model was evaluated by analyzing the average temperature of the roadway section, the cross-section distribution of the roadway temperature and the velocity streamline of the whole roadway. As a result, the air flow rate increases leading to the air temperature in the longwall decreases, however the wind speed is limited. The inlet temperature of the gas stream is an important factor that affects the thermal environment in the longwall. The results of the article are the basis for making solutions to improve the thermal environment suitable for high-temperature longwall.

Opis:
Vietnam is an Asian country with hot and humid tropical climate throughout the year. Forests account for more than 40% of the total land area and have a very rich and diverse vegetation. Monitoring the changes in the vegetation cover is obviously important yet challenging, considering such large varying areas and climatic conditions. A traditional remote sensing technique to monitor the vegetation cover involves the use of optical satellite images. However, in presence of the cloud cover, the analyses done using optical satellite image are not reliable. In such a scenario, radar images are a useful alternative due to the ability of radar pulses in penetrating through the clouds, regardless of day or night. In this study, we have used multi temporal C band satellite images to monitor vegetation cover changes for an area in Dau Tieng and Ben Cat districts of Binh Duong province, Mekong Delta, Vietnam. With a collection of 46 images between March 2015 and February 2017, the changes of five land cover types including vegetation loss and replanting in 2017 were analyzed by selecting two cases, using 9 images in the dry season of 3 years 2015, 2016 and 2017 and using all of 46 images to conduct Random Forest classifier with 100, 200, 300 and 500 trees respectively. The result in which the model with nine images and 300 trees gave the best accuracy with an overall accuracy of 98.4% and a Kappa of 0.97. The results demonstrated that using VH polarization, Sentinel-1 gives quite a good accuracy for vegetation cover change. Therefore, Sentinel-1 can also be used to generate reliable land cover maps suitable for different applications.

Opis:
The study was conducted to determine the factors affecting the intention of people to segregate garbage in Vinh Chau town, Soc Trang province, Vietnam by surveying 198 households. Cronbach’s alpha analysis method, EFA analysis, and linear regression analysis were used in the study. The analysis results of Cronbach’s Alpha index, KMO and Bartlett's test showed that the questionnaire data used in the study was highly reliable and were suitable for EFA analysis. The results of linear regression analysis identified three factors including "subjective norm", "control of cognitive behavior" and "perceived level of garbage classification information" that had positive impact on intention of domestic solid waste classification of local people in Vinh Chau town, Soc Trang province, in which "subjective norm" was considered to be the most influential factor on the intention to classify domestic solid waste in the study area. Besides, the intention of the people to segregate the domestic solid waste was highly appreciated, but it has not been widely implemented in the locality. Therefore, the study proposed some governance implications based on the factors affecting the intention of people to classify household solid wastes. In particular, local authorities should pay special attention to propagating and disseminating policies and guidelines on the information of domestic solid waste and implementing a model of waste segregation at source.

Opis:
The study was conducted to assess the impact of ownership concentration on the innovation of Small and Medium-sized Enterprises (SMEs) in Vietnam. Furthermore, innovation is seen as an important element in creating competitiveness to achieve long-term development for a company. This topic has been reported in many previous pieces of research where innovation is often measured through the number of patents. However, this study measures the innovation of SMEs through whether these businesses introduce products/services or introduce a new production process or new technology in 3 years. By Logit Bayes regression method, the research results show that ownership concentration harms the innovation of SMEs in Vietnam. The authors explain this result through channels like "access to capital" and the "Risk aversion" channels.
Badanie przeprowadzono w celu oceny wpływu koncentracji własności na innowacyjność małych i średnich przedsiębiorstw (MŚP) w Wietnamie. Ponadto innowacyjność postrzegana jest jako ważny element tworzenia konkurencyjności w celu osiągnięcia długoterminowego rozwoju firmy. Ten temat został poruszony w wielu poprzednich badaniach, w których innowacyjność jest często mierzona liczbą patentów. Jednak badanie to mierzy innowacyjność MŚP poprzez to, czy te firmy wprowadzają produkty/usługi lub wprowadzają nowy proces produkcyjny lub nową technologię w ciągu 3 lat.
