Breakthrough in the Development of Vietnamese Business in Order to Grow Rapidly and Sustainably

In the context of globalization and industrial revolution 4.0 (FIR), it is difficult to develop a national enterprise system to help the economy in the lower middle income group grow fast and sustainably. It is more difficult when that task is carried out in a country whose growth model has not had a solid foundation, to go in the right direction without any “deviation” or “discoloration". It is a breakthrough that must be chosen, with the nature of a "fundamental" stage that needs to be influenced, and this stage in Vietnam has developed significantly. However, it still has many limitations and weaknesses that, for many reasons, have not been overcome not easily. Nevertheless in the face of huge and urgent business development needs, it is possible to base on free trade agreements (FTAs), export commodities, FIR, and real-world fluctuations, to create a breakthrough business development. In particular, it is necessary to renew thinking techniques and developing methods of three business sectors, overcome difficulties, obstacles, exploit and make use of open opportunities to develop businesses. At the same time, it is necessary to ponder and apply deeper Korea's experience, rectify and mitigate risks according to warnings from China's economy and business development practices. Together with focusing on overcoming other indirect obstacles, then the mission of developing business in Vietnam, though very difficult, will be successful and full of hope to contribute much to the prosperity of the country...

STRUCTURE, ELECTRICAL PROPERTIES, AND APPLICATION POSIBILITY AS SOLID OXIDE FUEL CELLS CATHODE MATERIALS OF (La2NiO4±δ)1-x(BaTiO3)x(x=0.0-0.5) COMPOSITES

(La2NiO4±δ)1-x(BaTiO3)x (LNO/BTO), x=0.0, 0.05, 0.2, 0.3, 0.5 composites were prepared and investigated in structure and electrical properties. Single phase La2NiO4±δ component was obtained by sintering at 1000 oC during 12 h in air. Electrical conductivity was measured by 4-point probe method in wide temperature region above room temperature. Experiment showed that the highest conductivity was obtained in x=0.3 composite sample. Glass shell-nanocrystallite core structure of grains plays important role for this conducting enhancement. Conducting behavior of composites change from metal to semiconductor in the temperature interval of 400 to 700 oC. The LNO/BTO systems with acceptable electrical conductivity in such temperature interval are suitable for making cathode materials in solid oxide fuel cells

EFL students as creative writers

This article aims to share the author’s mini-action research in using some creative writing activities with Vietnamese high school students to examine how creative these EFL students could be in their writing of English and how useful creative writing can be to them. Three teaching activities were tried out as warmers with two groups of students in three different English sessions within two weeks. The outcome showed that these high school students were able to write creatively and their products could contribute to consolidating the benefits of creative activities in enhancing students’ mental and emotional development as advocated in various EFL contexts (Avramenko et al., 2018; Maloney, 2019; Manara, 2015; Pawliczak, 2015; Rippey, 2014; Şenel, 2018)

ANTIBACTERIAL ACTIVITY OF SILVER NANOPARTICLES SYNTHESIZED USING ELEUSINE INDICA L. GAERTN LEAF EXTRACT ON THE BACTERIA ISOLATED FROM THE VASE SOLUTION

Green synthesis of silver nanoparticles (SNPs) using Eleusine indica L. Gaertn leaf extract as a reducing agent is reported. SNPs were characterized through UV-Vis spectroscopy and transmission electron microscopy (TEM). The SNPs were rod like and spherical in shape with sizes from 3 to 33 nm and an average size of 16.73 nm. Seven bacterial strains were isolated from the vase water, including Bacillus cereus CA1, Alcaligenes faecalis CA2, Micrococcus luteus CA3, Pantoe agglomerans CA4, Pseudomonas aeruginosa CA5, Pseudomonas aeruginosa CA6, and Pantoe agglomerans CA7. Identifications were made according to Bergey’s Manual of Systematic Bacteriology and Bergey’s Manual of Determinative Bacteriology. The SNPs inhibited the growth of bacteria and exhibited significant antimicrobial activity against different isolated bacteria strains. SEM images showed that the SNPs damaged the cell membranes of bacteria, released plasmic contents, and altered the morphology of the cells. The impact of SNPs on gram-negative bacteria was more severe than on gram-positive bacteria. This study revealed that biosynthesized SNPs from Eleusine indica L. Gaertn leaf extract are potential agents in combating bacterial contamination

Board of Director’s influence on Innovation in Established Firms : An Exploratory Study

This thesis aims to explore how boards of directors in established firms facilitate innovation through exerting specific activities. We explore this phenomenon by conducting interviews with key informants who serve as board members in various established companies in Norway. Through in-depth semi-structured interviews with 18 informants, we find and present board members’ activities aiming to facilitate innovation within the organization. Our primary research question is: “Through what activities do board members aim to facilitate innovation within established firms”? We identify eleven activities that the board members who are closely involved in innovation adopt to facilitate innovation within the organization. These activities can be grouped into the three pillars of the dynamic capability framework, namely sensing, seizing, and transforming, which according to existing research are necessary organizational-level capabilities for innovation and to sustain competitive advantage. While previous research has focused on the role of top management, our findings show how board members can assist firms to develop these capabilities with their specific activities. Moreover, our research shows that some of the boards of directors have limited involvement in innovation and we identify internal and external factors hindering them from active involvement. We develop two models that show an overview of two types of board involvement with specific activities to foster innovation and contextual factors behind limited involvement. This study contributes to the existing literature by shedding light on the role of a new set of actors at the very top of the organizational hierarchy – the board of directions. Our study offers a set of empirically based activities practiced by board members that can enable organizational dynamic capabilities, aiming to ultimately result in enhanced innovation. Moreover, the study sheds light on various external and internal factors that can explain limited involvement of boards. In terms of practical implications, the research puts forth various activities that can be embraced by boards of directors seeking to enhance the established firms’ engagement in innovation. Additionally, the identification of factors behind limited involvement offers practitioners new perspectives to explore, with the aim of investigating and resolving this issue.nhhma

Description of Geocenamus vietnamensis sp. n. (Nematoda : Merliniidae) from Vietnam

A new species of the genus Geocenamus was isolated from soil and root samples from the rhizosphere of Casuarina equisetifolia (Casuarinaceae) in Quang Nam province, Vietnam. This species is characterized by a round-to-hexagonal labial disc, the presence of a labial region, which is continuous or slightly offset from the body with six sectors, lateral sectors of first labial annulus being smaller than the submedian sectors, the presence of six to seven labial annules; the absence of deirids; stylet length 24 to 28 mu m long, body length 776 to 979 mu m long; lateral field with six to eight lateral lines, without areolation at mid-body and with areolation in outer bands at the tail region and a pointed tail terminus. Geocenamus vietnamensis n. sp. most closely resembles G. boghiae in having a non-sclerotized head framework and lacking a bursa in the males. It can be clearly distinguished from all other species of the genus Geocenamus by these characteristics. The combination of morphology, morphometric features, and phylogenetic trees, based on D2-D3 of 28S and ITS rDNA sequences, showed that this new species can be clearly separated from all other sequenced species. This record is the first for Geocenamus in Vietnam

Reusability Of Zinc Oxide Nanorod For Photocatalytic Decomposition Of Rhodamine B Dye After Copper Metal Deposition

Advanced oxidation process based on semiconductor photocatalysts is an emerging technique for wastewater treatment. However, the lifetime of these semiconductor photocatalysts is yet to be fully studied. After heavy metal removal, most active sites of catalyst are blocked by heavy metal. Therefore, it affects the subsequent photocatalytic performance differently in organic dye removal. In this work, ZnO nanorods (NRs) and nanodisks (NDs) were synthesized by precipitation method and evaluate the photocatalytic activity to degrade Rhodamine B dye after heavy metal deposition. The average length and diameter of ZnO NRs were 497.34 ± 15.55 nm and 75.78 ± 10.39 nm, respectively. The ZnO NDs have average diameter of 2.12 ± 0.39 µm and thickness of 74.91 ± 17.67 nm. The photodegradation of RhB dye by ZnO particles followed first-order kinetic reaction. ZnO NRs removed effectively heavy metal ions such as Cu(II), Ag(I) and Pb(II) ions with efficiency of 100%, 97.92% and 85.18%, respectively under exposure of UV light for 1 hour. However, poor removal efficiency, i.e. 14.83%, 8.62%, 7.23% and 4.76%, respectively was observed for Cr(VI), Mn(II), Cd(II) and Ni(II). These heavy metal ions were removed in the forms of metals or metal oxide via reduction/oxidation or adsorption mechanisms. The degradation efficiencies of RhB dye by Cu/ZnO, Ag/ZnO, Mn/ZnO, Cd/ZnO and Ni/ZnO hybrid particles were better than ZnO particles but not the case of Pb/ZnO and Cr/ZnO hybrid particles. In conclusion, the ZnO NRs in general showed a remarkable ability to degrade RhB dye under UV irradiation after heavy metal deposition
