In this work the concept of generally covariant duality is treated with the introduction of generalized Levi-Civita tensor within the framework of vierbein formalism. The equations for the attached Lorentz scalar fields are derived from vierbein postulate. It is shown that the masses of the associated particles including that with negative square mass are completely determined by Einstein’s cosmological constant.

To study an application of low-value fishmeal (i.e. organic manure) and the effect of different nitrogen (N) and phosphorus (P) ratios (N/Ps) to the composition of algae prevailing in fertilized ponds for culturing Artemia. Phytoplankton composition and their abundance were determined through qualitative and quantitative sampling and analyses. The experiment included five treatments, control treatment using chicken manure (300 g/m^3), the others with fishmeal in different rates (i.e. 30 g/m^3, 60 g/m^3, 90 g/m^3, 120 g/m^3) with 3 replicates each and in a combination with inorganic fertilizer. Result indicated that the algal density of the experiment varied from 318 × 10^3 to 2,590 × 10^3 cells/mL and a significant difference among treatments (p < 0.05). The density of algae at the second treatment (30 g/m^3) is the highest with a mean density of 2,590 × 10^3 cells/mL. There are 38 phytoplankton species belonging to five phyla of algae, i.e. Bacillariophyta, Cyanophyta, Chlorophyta, Dinophyta and Euglenophyta. Also, there are 18 species of Bacillariophyta, 14 species of Chlorophyta, 4 species of Cyanophyta, 1 species of Dinophyta and 1 species of Euglenophyta. Algae compositions were 32, 34, 31, 27 species at control treatment, and 30 g/m^3, 60 g/m^3, 90 g/m^3, 120 g/m^3 fishmeal treatments, respectively. The dominant genus was usually Nitzschia, Thalassiosira, Navicula (Bacillariophyta), Tetraselmis (Chlorophyta), Oscillatoria (Cyanophyta), Euglena (Euglenophyta). Euglena usually appeared in the late phase of the experiment.

Born as Ly Cong Uan, Ly Thai To is the first king of the Ly Dynasty. The most important contribution of Ly Thai To in Vietnamese history is to move the capital from hoa Lu to Dai La, and rename it as Thang Long （Ascending Dragon） in 1010. Nowadays, it is known as Hanoi. Ly Thai To promoted Buddhism, and reduced the centuries-old influence of Confucianism in the kingdom. The growth and prevalence of Buddhism brought about a long period of peace, where Buddhist literature consequently flourished with seminal achievements. Due to King Ly Thai To＇s enormous contributions, the Vietnamese have created several legends and anecdotes to mystify his life. Thus, although a historical figure, his life remains a mystery and controversy. In 2010, Hanoi celebrated the 1000th anniversary of Thang Long. On this occasion, Vietnamese historical films about Ly Cong Uan were produced. This created intriguing variations within historical facts, legends, and on-screen stories. This paper will explore the reconstruction of Ly Cong Uan＇s life from an adaptation studies perspective through four historical films： Legend of the Capital Relocation （Huyen su thien do）, Thang Long Aspiration （Khat vong Thang Long）, Ly Cong Uan The Road to Thang Long Citadel （Ly Cong Uan： Dtrong toi thanh Thang Long）, Child of the Dragon （Ngtroi con cua Rong）. This research also wants to clarify the issues of national identity, nationalism, and cultural interaction reflected through the representations of Ly Thai To in those cinematic products

Vietnam’s economy has been developing strongly in recent years;however, it is necessary to examine the impact of its economic activities on environmental quality. This study aims to evaluate the relationship between CO2 emissions and economic growth, industrial production, and foreign direct investment (FDI) in Vietnam. The ARDL estimation was used to process the dataset from World Bank. Results showed that economic growth, industrial production, and FDI have an impact on CO2 emissions in the long run in Vietnam. Granger Causality test also indicated that there is a causal relationship between economic growth, industrial production, and CO2 emissions in Vietnam from 1990 to 2018, at 5% statistical significance level. Proposed solutions to reduce CO2 emissions but still promote economic growth toward the green growth orientation and zero carbon target attainment are as follows: 1) reduce the use of fossil energy in industrial manufacturing and replace it by renewable energy sources;2) use modern technology for all production sectors in economy;and 3) develop a legal framework for FDI projects selection and choose foreign investors with modern and low carbon emission technology.
