    Opis:
    Researchers have paid significant attention on hyperjerk systems, especial hyperjerk ones with chaos. A new hyperjerk system with seven terms and two parameters is analyzed. Chaotic attractors as well as coexisting attractors are displayed by the hyperjerk system. Thus it is a new multi-stable chaotic hyperjerk system. Further properties of the proposed hyperjerk system such as circuit design and backstepping-based control and synchronization are reported.

    Opis:
    We study an elegant snap system with only one nonlinear term, which is a quadratic nonlinearity. The snap system displays chaotic attractors, which are controlled easily by changing a system parameter. By using analysis, simulations and a real circuit, the dynamics of such a snap system has been investigated. We also investigate backstepping based adaptive control schemes for the new snap system with unknown parameters.

    Opis:
    ASEAN (The Association of SouthEast Asian Nations) demand on energy is depending on economic growth of each country, resources, and political and regulations of each country. This study aims to investigate the role of international trade, financial development, foreign direct investment (FDI) on the consumption of renewable energy (RE) in ASEAN countries of the world. The findings explore that positive nexus among the international trade, real output, financial development, foreign direct investment and consumption of RE. Last but not least, this paper will propose several recommendations and policy suggestion for ASEAN countries to manage and encourage better renewable energy projects in the region. One of its original value is that, in the globalization and integration era, environment pollution will affect all ASEAN countries and in the region, so these nations need to link together to implement renewable projects for environment protection and for further generation.

    Opis:
    Recently, because of serious global challenges including the consumption of energy and climate change, there has been an increase in interest in the environmental effect of port operations and expansion. More interestingly, a strategic tendency in seaport advancement has been to manage the seaport system using a model which balances environmental volatility and economic development demands. An energy efficient management system is regarded as being vital for meeting the strict rules aimed at reducing the environmental pollution caused by port facility activities. Moreover, the enhanced supervision of port system operating methods and technical resolutions for energy utilisation also raise significant issues. In addition, low-carbon ports, as well as green port models, are becoming increasingly popular in seafaring nations. This study comprises a comprehensive assessment of operational methods, cutting-edge technologies for sustainable generation, storage, and transformation of energy, as well as systems of smart grid management, to develop a green seaport system, obtaining optimum operational efficiency and environmental protection. It is thought that using a holistic method and adaptive management, based on a framework of sustainable and green energy, could stimulate creative thinking, consensus building, and cooperation, as well as streamline the regulatory demands associated with port energy management. Although several aspects of sustainability and green energy could increase initial expenditure, they might result in significant life cycle savings due to decreased consumption of energy and output of emissions, as well as reduced operational and maintenance expenses.

    Opis:
    A sediment budget for the central Vietnam shelf off Nha Trang over the last deglacial Holocene highstand period has been investigated on the basis of shallow seismic and sediment core data and empirical equations. The annual suspended sediment discharge to the Nha Trang shelf ranges from: 4.3 to 5.4 Mt/year. Estimates based on published empirical equations suggest that the sediment discharge by three main local mountainous rivers (the Cai, Dinh and Van Phong rivers) that enter the Nha Trang shelf ranges between 1.7 and 4 Mt/year, which implies that the local rivers discharge approximately 75% of the total annual sediment input to the shelf. The annual sediment supply of the Cai River is approximately 2 and 6 times higher than that of the Dinh and Van Phong rivers, respectively. The highstand sediment depocentre of the Nha Trang shelf is mostly attached to the local river outflows, indicating their importance as the principal sediment supply sources to the shelf. Additional sources of sediment supply to the Nha Trang shelf can probably be related to along-shore transport from the nearby shelves. Calculations based on seismic and sediment core data indicate that the net sediment volume storage on the Nha Trang shelf is approximately 2.15 Mt/year. Approximately 50% of the total sediment yield supplied to the shelf is probably transported along-shore to the south. The sediment budget model for highstand deposits on the Nha Trang shelf is typical for a small mountainous river basin, which is significantly different from that of the large river delta systems in Vietnam such as the Mekong and Red rivers where 90% of the river sediments are captured on the delta plain/subaqueous part and only 10% of the river sediments are transported to the nearby shelf. In contrast, most of the sediments supplied by small mountainous rivers off Nha Trang are transported to the mid-shelf, forming a shore-parallel mud depocentre.

    Opis:
    The studFigy aims to determine the TNF-α single-nucleotide polymorphism TNF-α (-308) and assess the association of TNF-a(-308) SNP with the risk of silicosis among workers directly exposed to silica dust in Vietnam. A study was undertaken among 78 cases with silicosis and 103 controls without silicosis in Vietnam. Blood samples were collected for genomic DNA extraction from each subject. The phenotyping of TNF-α(-308) was performed using polymerase chain reaction‐based restriction fragment length polymorphism (PCR‐RFLP) and dye termination sequencing. Results: The average exposure time of the case group was slightly higher than that of the control group (12.46 ± 6.732 years vs. 12.09 ± 7.854 years). The majority of genotypes in both silicosis and non-silicosis was GG. When analyzing the concentration of TNF-α in the study participants' blood, it is shown that the average concentration of TNFα in the case group was higher than that in the control group. The genotype AG in the case group was 1.368 times higher than that in the control group. The percentage of all A alleles in the case group with silicosis was 1.342 times higher than the control group without the disease, similar to previous studies. Conclusion: The majority of genotypes in both groups was GG. The average concentration of TNF-α in blood, genotype AG, and the percentage of all A alleles in the case group was higher than that in the control group.
