Sargassum macrocarpum is a perennial brown macroalga that forms the most important portion of seaweed beds with sufficient biomass. Algae have been proven to be beneficial functional food and pharmaceutical material. The...

With the arrival of big-data society, methods for classifying real-world problems have attracted much attention for researchers and developers in various fields. In recent years, much effort has been devoted for improvin...

Today, CAD/CAM is increasingly gaining its importance in the field of mechanical design. However, these systems are not operated easily by those without proper computer programming skills. This paper aims to allow these ...

We have investigated the intestinal absorption and metabolism of the polyphenols contained in Acanthopanax sieboldianus Makino (Ukogi in Japanese) in rat plasma using a liquid chromatography/mass spectrometry (LC/MS). Uk...

It has investigated using a Clark-type oxygen electrode and an ESR method that the conformation of thiol-compounds such as cysteine (Cys) and glutathione (GSH) effects on the formation of a nitrosyl(protoporphyrinato)iro...

Currently used methods for selenium quantification include X-ray fluorescence spectrometry and inductively coupled plasma analysis. However, both methods require expensive equipment, specialized knowledge, making them un...

When hair is wet, the cuticles are open, therefore, it is easy to damage the hair through too much use of a regular hair-dryer. In this research, instead of the current type of heat-blow dryer, a new type of hair-dryer w...
