The study investigated the potential for facial electromyography (EMG) to be used as a clinical tool for measuring the responses of children to pleasant and unpleasant smell and taste stimuli. Responses in the zygomaticus major and levator labii muscles to 4 odorants and 4 tastants were recorded from 34 children aged 6-9 years. The results indicated that EMG activities in the 2 muscles discrimi...

We investigated the role of transcription factors (R, SN, C1, and PL) in the regulation of anthocyanin biosynthesis by different light qualities (white, red, blue, and ultraviolet) and by cytokinin in maize (Zea mays). We analyzed anthocyanin accumulation, structural gene expression, and regulatory gene expression in the seed aleurone and the seedling mesocotyl. In the mesocotyl, white, blue, a...

Nowadays, lighting planning is predominantly determined by the need to meet physically measurable requirements that are often based on current standards. However, meeting minimum technical of standards no guarantee for a visually appealing light environment. Instead, perceived qualities also be included achieve better user comfort. Taking perception-based into consideration when creating enviro...

Randall, Wesley C. M.S., Purdue University, August 2014. Supplemental, end-of-day, and sole-source lighting from light-emitting diodes influences growth, morphology, and quality of annual bedding plant seedlings. Major Professor: Roberto G. Lopez. Annual bedding plants make up the largest sector of the U.S. floriculture industry. Highquality annual bedding plant seedlings are compact, fully roo...

Light has a profound effect on plant growth and development. Red and blue light best drive photosynthetic metabolism, so it is no surprise that these light qualities are particularly efficient in advancing the developmental characteristics associated with autotrophic growth habits. Photosynthetically inefficient light qualities also impart important environmental information to a developing pla...

Drawing on remarks scattered through his writings, I argue that Leibniz has a highly distinctive and interesting theory of color. The central feature of the theory is the way in which it combines a nuanced subjectivism about color with a reductive approach of a sort usually associated with objectivist theories of color. After reconstructing Leibniz’s theory and calling attention to some of its ...
