The paper studies the cohomology of Lie algebras and quadratic Lie algebras. Firstly, we propose to describe the cohomology of $MD(n,1)$-class which was introduced in \cite{LHNCN16}. This class contains Heisenberg Lie algebras. In 1983, L. J. Santharoubane \cite{San83} ...

In Vietnam, school violence is a serious problem; yet, little is known about the factors explaining this phenomenon. The current study looked at the role of normative beliefs approving aggression in the development of overt aggressive behavior. Using a short-term longi...

Tributyltin (TBT) is organotin compound that is toxic to aquatic life ranging from bacteria to mammals. This study examined the concentration of TBT in sediment from and near the Mekong River and the distribution of TBT-resistant bacteria. TBT concentrations ranged from...

Wildlife trade can present a major threat to primate populations. In Vietnam, slow lorises (genus Nycticebus) are subject to local, regional and international demand for diverse uses including as medicine, as meat and for pets. Ethnographic approaches explore the nuance...

Resource shortages are having an increasingly severe impact as global trends like rapid population growth, urbanization, economic development, and climate change unfold. Moreover, rising living standards across many regions are also affecting water and energy resources....

This research proposes a combined-drying system as a design solution to improve the performance of conventional solar drying systems in terms of the uniformity of taste and humidity remain in dried crops thanking to controlled and stabilized drying parameters. The desig...

International audience; Our investigation aims at classifying images of the intangible cultural heritage (ICH) in the Mekong Delta, Vietnam. We collect an images dataset of 17 ICH categories and manually annotate them. The comparative study of the ICH image classificati...

Shear recentering polyurethane friction damper is a type of passive control device, including the shape memory alloy plates, polyurethane springs, and friction devices. This damper can be employed in the shear link of an inverted Y-shaped braced frame. As the failure m...

All indecomposable finite-dimensional representations of the homogeneous Galilei group which when restricted to the rotation subgroup are decomposed to spin 0, 1/2 and 1 representations are constructed and classified. These representations are also obtained via contract...
