Biological properties and biomass culture of the microalgae chaetoceros muelleri from Giao Thuy mangrove for use in aquacultureFatty acid composition. Microalgae is a potential resource of fatty acids, particularly polyunsaturated fatty acids, PUFAs, which are of major importance determining the nutritional value of microalgae [5, 11, 13]. Fatty acid composition of C. muelleri was characterized and shown in Table 2. The distribution of fatty acids in C. muelleri is si...

The nutritional value of diatoms from giao thuy mangrove water of the red river delta biosphere reserveThe three diatom strains have a great variety of fatty acids ranging from saturated fatty acids (10:0 - 22:0) to polyunsaturated (18:2 - 22:6) fatty acids (Table 2). Among them, the saturated fatty acids palmitic (16:0) and the monounsaturated palmitoleic (16:1n-7) were dominant. They accounted for 60 - 80% of the total fatty acid. Myristic acid...

ECG dipole source localization in 3D human modelWe used 50 dipoles with different orientations, magnitudes and positions as above. These dipoles are enough to estimate the effectiveness of our approach. The source localization was carried out three times to confirm the reliability of the obtained solution. The results in Table 3 show that the errors of dipole locations are acceptable. The av...

Simulation study of tracer self - Diffusion mechanism in cobalt amorphous solidsConclusion The microstructure for the cobalt model containing 2 × 105 atoms is in good agreement with experimental data. The simulation result reveals that a large number of vacancy-simplexes which varies with relaxation degree in amorphous cobalt models. The relaxation has been accompanied with increased fraction of 4-simplex and decreased fra...

Study on treatment of alkaline black liquor using sulphate reducing bacteriaThese paper mills used alkaline pulping method have neither recovery line nor wastewater treatment due to very small capacity and economic problem. Their black liquor effluents directly discharge to the rivers and cause heavy pollution to the aquatic lives and people living at the delta of the rivers. The chosen strains were used for treatment ...
