The paper "The role of orographic effects on heavy rainfall event over central Vietnam in October 2021" use observation data and high-resolution (3 km) simulations from the WRF model, driven by FNL data, to investigate the causes of heavy rain over Central Vietnam from 22nd to 29th October 2021. Our findings confirm the significant role of topography in causing heavy rain. In terms of the atmosphere’s vertical structure, the surface’s northeast wind, almost perpendicular to the Central region’s topography, combined with the east wind and trade winds above, caused strong convection.

Ebook "Crystallization of nanoscaled colloids" deals with the processes that create ordered assemblies from disordered nanoparticles. Ordered packings of nanoscale particles can exhibit unusual properties. This work investigates the self-assembly of such particles, a process widely employed for the generation of ordered structures, but not yet well understood. In situ methods are used to observe the assembly of sub-micron polymer lattices and sub-10 nm gold particles into crystalline monolayers and aggregates.

Ebook "Modelling electroanalytical experiments by the integral equation method" begins with models independent of spatial coordinates, goes on to address models in one dimensional space geometry and ends with models dependent on two spatial coordinates. Bieniasz considers both semi-infinite and finite spatial domains as well as ways to deal with diffusion, convection, homogeneous reactions, adsorbed reactants and ohmic drops.

They have an impact on the evidence published earlier for the presence of CO masers. They favour an interpretation in terms of convective cell ejections playing the main role in the generation of the nascent wind, the stable component of the CSE being seen as the result of many successive such events occurring in different directions at short time intervals.

In this study, we apply an artificial viscosity method to convert an unsteady level set (LS) convection equation into an unsteady LS convection-diffusion transport equation to stabilize the numerical solution of the convection term. Then a novel least-square polygonal finite element method is used to solve an unsteady LS convection-diffusion problem.
