Extraction techniques

In this research, a single-step polymeric novel particle was synthesized from oak bark extract by nanoemulsion polymerization technique for the first time in the literature. It has been shown that the synthesized particles are achieved without losing any antioxidant and antibacterial properties of the oak bark extract. In this study, the p(OB) particles were reported for the first time and were characterized in terms of antioxidant, blood compatible, H2O2 scavenging, antibacterial, and antifungal potential to evaluate their use in biocompatible materials with drug release system potential.

In recent studies, Azadirachta indica, Andrographis paniculate, Ocimum canum and Pongamia pinnata, which are inhibitors derived from plants have been used to provide corrosion inhibition effect. The inhibitive ability of C. albidum in several corrosive media reported by researchers has prompted its examination in 1 M H2SO4 solution using polarization techniques, gravimetric and gasometric in this present work.

This study extracts images from Taekwondo videos and generates skeleton data from frames using the Fast Forward Moving Picture Experts Group (FFMPEG) technique using MoveNet. After that, we use deep learning architectures such as Long Short-Term Memory Networks, Convolutional Long Short-Term Memory, and Longterm Recurrent Convolutional Networks to perform the poses classification tasks in Taegeuk in Jang lessons. This work presents two approaches. The first approach uses a sequence skeleton extracted from the image by Movenet.

The methanol extracts as well as some compounds from this plant exhibited anti-inflammatory, antimicrobial activity, antioxidant, hepatoprotective and anti-cancer effect, and antiosteoporotic. On going to search for bioactive components from the Vietnamese plant, this paper reported the isolation of seven phenolic compounds including one new from the aerial parts of A. ilicifolius. The cytotoxic activity of the isolates against two cancer cell lines (HepG2 and SK-LU1) were also screened and reported herein.

Delay is one of the serious problems in the construction industry, particularly in high-rise building construction projects in Thailand. Therefore, this research aims to investigate the major resource supply causes and effects of delay problems in high-rise building construction projects in Thailand. The study employs both quantitative and qualitative study with concurrent mixed method design. Thirty-three resource supply causes and nine effects extracted from the literature review were used as the basis for further analysis.
