Ebook "Helical wormlike chains in polymer solutions (Second edition)" presents the "helical wormlike chain" model – a general model for both flexible and semiflexible polymer chains. It explains how statistical-mechanical, hydrodynamic, and dynamic theories of their solution properties can be developed on the basis of this model. This new second edition has been carefully updated and thoroughly revised.

This study sheds light on the post-equilibrium sea bed scour mechanism around a wind turbine. The simulation results explain the influence of different hydrodynamic mechanisms on the local scours in a cohesive fluid, such as periodic waves, random waves, and constant currents. The conventional Bingham model is adopted as the fundamental model. However, due to the intrinsic characteristic, the Bingham model cannot illustrate the stratified material satisfactorily.

This paper gives an illustration of using the computational fluid dynamics approach to investigate the movement of the solution inside the hand-washing chamber. The numerical results obtained from the numerical simulation demonstrate the hydrodynamic values, streamlines, and density of the solution. The ability to predict the handwashing chamber's hydraulic and cleaning performance efficiencies is essential for evaluating the operability and improving the further design.

The low-lying terrain in downstream area of Sai Gon - Dong Nai river is mostly affected by natural disasters such as flooding, saltwater intrusion causing difficulties in process of socio-economic development. The project of building Vung Tau - Go Cong sea dyke with a length of 32 km was proposed to solve these problems, particularly creating a reservoir for storing water and preventing saltwater intrusion, expanding urban space, industrial parks, tourism, services, shelter for boats from the storm, reserving fresh water in the future.
