Heavy fuel oil (HFO) obtained from crude oil distillation is a widely used fuel in marine engines and power generation technologies. In the present study, the combustion characteristics and performance of heavy oil are investigated. Further research on heavy oil is developed by adding content of Liquefaction Bio-Oil, because of its complex nature. So as to better understanding of HFBO combustion process and to improve efficiency and control emissions. The techniques used to study the heavy oil is TGA-FTIR, Single droplet, Gas analyzer and Spray combustor. All the required techniques are used to investigate heavy fuel blended oil (Mixture of heavy oil and Liquefaction Bio-Oil) combustion behavior with various HBFO of 3%, 5%, 7% and 10%. The combustion behavior of heavy fuel blended oil was performed using the thermo-gravimetric analysis (TGA) at temperature 30 °C to 800 °C at various heating rates of 5°C/min and 10°C/min in air atmosphere. TG and DTG were used to study the mass loss characteristics due to the thermal degradation of HFBO. Single droplet and spray combustion experiments of heavy fuel oil with Liquefaction Bio-Oil are used to investigate the evaporation, atomization, combustion behavior and improve efficiency. The results show that improve in the combustion performance and characteristics of heavy fuel blended oil by using TGA. The droplet test results are good agreement with HFO and heavy fuel blended oil (HFBO) in two cases, found that ignition temperature, burnout temperature and combustion index are more satisfactory.

This research focuses on factors affecting the ability to achieve Environmental Standards Certification (ESC) at Vietnamese small and medium enterprises. Logit regression was used with crossectional data of 2649 Vietnamese small and medium enterprises. The results show that customer requirement, administration level, owner/manager characteristics (ethnicity and environmental law knowledge), the type of firms, the size of enterprises, government inspection, and union affect the ability to achieve ESC. From the results, some solutions have been suggested in order to increase the ability to obtain ESC of small and medium enterprises and thus contribute to Vietnam's environmental protection.

This paper proposed an image preparing technology to remove completely the noise effects of unexpected conditions and actually extract primary feature of human pose in indoor environment. Color image conversation with YCbCr, enhanced image intelligibility with a median filter, one OPEN operation and one labeling algorithm, are applied to detect the object‘s boundary. A dynamic image segmentation matching algorithm generated human feature vectors, which are used to search the most similar pattern for approximating the correct human pose. Several experiments show that the proposed dynamic image segmentation matching algorithm actually detected the real characteristics of human pose and makes the great support to re-cover the various image feature problem in complex environment. Future work for an intelligent human pose is used to virtually control home equipment in everywhere.

Nowadays, the rapid detection of short-circuit faults in the distribution network is very necessary aiming to increase the reliability of the electric network. The shorter the time of detection of faults is, the faster the recovery of the normal operation of the distribution network is. However, this task contains a challenge due to the complexity of distribution networks that are using both overhead and underground cables. Recently, many research activities are presented to detect the short-circuit fault in a distribution network and classified into three catalogs: (i) time domain reflection, (ii) traveling wave method, and (iii) impedance method. However, the first two methods have a very high investment cost, thus they are not used widely in distribution networks even their efficiency performance is confirmed. Therefore, this paper aims to study on many algorithms; e.g. Tagaki, Saha, Personal Algorithm; which are developed based on the last method, then a program is implemented in Matlab Simulink in order to test various algorithms. Moreover, these algorithms are tested with two real underground cables in the Center of Vietnam to figure out the best algorithm for the real application in Vietnam.
为了提高配电网的可靠性，快速检测配电网的短路故障是十分必要的。发现故障的时间越短，配电网恢复正常运行的速度就越快。然而，由于使用架空和地下电缆的配电网络的复杂性，这项任务包含一个挑战。近年来，国内外对配电网短路故障检测的研究较多，主要分为时域反射法、行波法和阻抗法三大类。然而，前两种方法的投资成本很高，因此即使它们的效率性能得到证实，也没有在配电网中得到广泛应用。因此，本文旨在研究多种算法;例如Tagaki, Saha, Personal Algorithm;然后在Matlab Simulink中编写了一个程序，对各种算法进行了测试。并在越南中部的两条真实地下电缆上对这些算法进行了测试，以找出适合越南实际应用的最佳算法。

This study was conducted to evaluate the antimicrobial property of polyester filter cloth embedded with copper nanoparticles by a green chemical method. Copper nanoparticles were generated in situ on pieces of commercial polyethylene terephthalte (PET) filter cloth by reducing [Cu(OH)4]2- ions by ascorbic acid in aqueous solution. Elemental analysis using energy-dispersive X-ray (EDX) spectrum of the modified filter fabric confirmed the presence of copper (0.15-0.35 $mu$g/mm2). Analysis of scanning electron microscope (SEM) images showed that the sizes of synthesized copper particles varied from less than 100 nm to over 500 nm. Increasing ascorbic acid concentrations while fixing cuprate ion concentration resulted in higher load and lower sizes of deposited copper nanoparticles. Antibacterial activity of the modified polyester filters was assessed by passing suspensions of Escherichia coli NBRC 14237 in phosphate-buffered saline (PBS) and in sterilized milk through these modified filters. Analyzing the effluent for viable bacteria showed that the antibacterial activity against E.coli in PBS was about 12 times more effective than that in milk. Moreover, increasing copper nanoparticles load on the filter resulted in increasing antibacterial effect toward E.coli. Leaching test showed that concentration of copper in the effluent after passing distilled water (1000 and 2000 m3/m2) through the modified filter was below the recommended limit for copper in drinking water (1 ppm).

Bone tissue engineering has attracted a lot of research attention recently as an interdisciplinary subject aiming to restore, maintain, and improve the functions of bone. The procedure of bone tissue engineering is based on the combination of three main factors, including biomaterials, cells and bioactive molecules. Interestingly, the natural bone structure is quite similar to diatom biosilica and both of them are formed from biomineralization. Following the development of technology, mimicking natural phenomenon have become upward trend of engineered bone scaffold materials. Here, we summarize condensed knowledge about diatom biosilica formation, bone tissue engineering and recent advanced applications of diatom biosilica for bone tissue engineering.

In the present study, the wing of the seed of the green maple was used as the imitated object, and the shape of the seed wing was analyzed. The setup of experiment and parameters design of the bionic wind turbine blade was then progressed by Taguchi method and the ANSYS Fluent simulation software was used to perform the numerical computations of the aerodynamic and flow characteristics of the wing of maple’s seed. Also, based on the experiment and simulation results, the Minitab17 software was used to analyze the data. The simulation results, by an inspection of the trend of the lift coefficient curves, indicated that the seed wing of the green maple has a larger range of angle of attack, $0 ^{mathbf {0}}$ to $50^{mathbf {0}}$, without a stall. The results for the optimal design parameters show a good agreement with the achievement for the best combination of the parameters are: A3 (the number of blade = 3), B3 (the swept area = ${0.24,,mathrm{m}} ^{mathbf {2}}$), C2 (the angle attack = $15^{mathbf {0}}$) and D2 (the steady headwind = 5 m/s., which shows an aerodynamic advantage. In addition, the wind tunnel experiments of the wind turbine, with 3 bionic blades, $0.24,,mathrm{m}^{mathbf {2}}$ swept area, $15^{mathbf {0}}$ angles of attack, and 5 m/s steady headwind conditions showed that the highest wind/electricity power transform efficiency can be reached up to 37%.
