This article presents the development of wood flour (WF)-filled polylactic acid (PLA) composite filaments for a fused deposition modeling (FDM) process with the aim of application to 3D printing.

In this article, permeability properties and surface roughness of stainless steel (SS316L) surfaces were evaluated through experimentation with three different laser scanning patterns (chessboard, meander, and stripe), and different sloping angles between the fabricated surface and the laser beam incident on the process. Results showed that for each scanning pattern, the roughness decreased as the sloping angle increased consistently in all experimental trials.

The article discusses crucial markers in identifying biological elements and processes in mammalian genomes, CpG islands (CGI) that play important roles in DNA methylation, gene regulation, epigenetic inheritance, gene mutation, chromosome inactivation and nuclesome retention. A novel Gaussian model, GaussianCpG, is developed for detection of CpG islands on human genome. Their Gaussian model aims to simplify the complex interaction between nucleotides.
