Effects of two different light intensities during daytime were examined on human circadian rhythms in plasma melatonin, core body temperature, and wrist activity under a fixed sleep schedule. Sleep qualities as indicated by polysomnography and subjective sleepiness were also measured. In the first week, under dim light conditions ( approximately 10 lx), the onset and peak of nocturnal melatonin...

Here, we analyzed the effects of light regulation on four selected histone modifications (H3K4me3, H3K9ac, H3K9me2, and H3K27me3) and the relationship of these histone modifications with the expression of representative light-regulated genes. We observed that the histone modifications examined and gene transcription were cooperatively regulated in response to changing light environments. Using ...

Bioplastics are biodegradable polymers that made by bacterial cells, whose molecules have biochemical properties similar to petrochemical as they concentrated inside intracellular granules a carbon and energy sources, which then degrade in the environment get exposed light. desirable renewable qualities, sustainable qualities well alternatives petroleum-based plastics, is used due much of its b...

In the lycosoid spiders, the secondary eyes possess a grate-shaped tapetum lucidum that reflects light, causing eyeshine when these spiders are viewed with approximately coaxial illumination. This guanine-based reflective surface is thought to increase visual capabilities in low light. We explored the eyeshine of the posterior medial eye in eight taxa of pisaurid and lycosid spiders. The taxa i...

AbstrAct Linguistic qualities are essential for the fitness for use of every standard. The intentions of the standards developers should become perfectly clear to those who will finally use the documents, but language barriers at several project stages may hinder this. This chapter addresses the topic for standards at the global and regional levels using a case study about the linguistic qualit...

facial expression. A disembodied voice would be a detriThis paper explores the expression of emotion in synment to a life-like quality of interaction that we would like thesized speech for an anthropomorphic robot. We have Kismet to have with people. Synchronized movements of adapted several key emotional correlates of human speech to the robot's speech synthesizer to allow the robot to speak t...

Parents’ socialization goals are important for cultural transmission across generations, but whether such goals vary by ethnic and socioeconomic backgrounds and change over children’s first years of life remains unexamined. In Study 1, African-American, Dominican immigrant, and Mexican immigrant mothers (N = 300) reported on the qualities deemed as desirable or undesirable when children were ag...
