Research ArticleOpen accessIn the abstractLED TECHNOLOGY FOR BUILT AND ENVIRONMENT OF MALAYSIAC. H. Lim, Masoud Dalman, Mona Erfanian Salim et al.Increasing the country population and the trend of industrialization caused increasing Malaysia's electricity consumption. Light Emitting Diode (LED) is a new sustainable technology that has taken over the conventional lighting in built and environment in a few developed counties in the recent years. However, Malaysia is left behind in using this technology due to unfamiliarity of the decision makers on … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 1 Oct 2014 · 6,863 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordBlue and White LED Lights Enhance Biosynthesis of Rosmarinic Acid in Cell Culture of Agastache rugosaWoo Tae Park, Sun Kyung Yeo, Nam Su Kim et al.Agastache rugosa, an herbaceous Korean perennial, contains pharmacologically important phenylpropanoids such as tilianin and rosmarinic acid. However, the knowledge of biosynthesis of phenylpropanoids from A. rugosa is limited. Therefore, a study was conducted to develop an efficient protocol for in vitro regeneration of A. rugosa and to investigate the influence of three different LED light wavelengths (white, blue and red) … …OnLine Journal of Biological Sciences, Vol. 20, Issue 2 · 24 May 2020 · 6,860 accessesView PDFCite
