Features of Application of Road Clinker Brick of Light Color

As a branch of watercolor painting, watercolor light color has been widely used in different fields. In the field of design, designers use the convenience, quickness, transparency and brilliance of watercolor to draw a design drawing. In the field of art creation, watercolor is usually the best choice for painters to go out to sketch and create large-scale drawings. In the field of art education, watercolor tools are easy to carry, low-cost and easy to operate, which can facilitate students’ repeated practice and outside Sketching is helpful to cultivate students’ sense of color and observation ability. Therefore, as a branch of art curriculum, watercolor light color has a wide range of uses and great practicability, which is worth exploring and studying.

Design Experiments

In an attempt to bridge the gap between architectural/interior design practice and education, ‘atmosphere’ as a prolific contemporary architectural debate in practice and theory is covered by the experiment of ‘Staging Poe’ carried out as a first year Design Studio through the study of Edgar Allen Poe’s selected poems. Poe’s 1846 text of ‘The Philosophy of Composition’, unfolding his analytical method of writing and emphasis on “effect” in poetry, provides a ground for experimenting with facets of materiality and structuring the studio. Aiming to cultivate intuitive design experiments of students into informed processes in hybridizing conceptual/textual and material/sensual aspects, studio is structured in two phases. In the first phase, “materialization”, idiosyncratic interpretations of students from words to materials with a focus on tectonic experiments and haptic experiences are sought in between materializing and dematerializing processes. In the second phase, the “atmospheric”, emphasis on dematerialization of the perception of materials through tools, such as light, color and sound is exercised to transform the object into a performance stage. Outcomes of the studio on aspects pertaining to material and materialities in creation of the immaterial that is the atmosphere is followed and evaluated through responses of students’ weekly reports.

ABSTRACT RcaC is a large, complex response regulator that controls transcriptional responses to changes in ambient light color in the cyanobacterium Fremyella diplosiphon. The regulation of RcaC activity has been shown previously to require aspartate 51 and histidine 316, which appear to be phosphorylation sites that control the DNA binding activity of RcaC. All available data suggest that during growth in red light, RcaC is phosphorylated and has relatively high DNA binding activity, while during growth in green light RcaC is not phosphorylated and has less DNA binding activity. RcaC has also been found to be approximately sixfold more abundant in red light than in green light. Here we demonstrate that the light-controlled abundance changes of RcaC are necessary, but not sufficient, to direct normal light color responses. RcaC abundance changes are regulated at both the RNA and protein levels. The RcaC protein is significantly less stable in green light than in red light, suggesting that the abundance of this response regulator is controlled at least in part by light color-dependent proteolysis. We provide evidence that the regulation of RcaC abundance does not depend on any RcaC-controlled process but rather depends on the presence of the aspartate 51 and histidine 316 residues that have previously been shown to control the activity of this protein. We propose that the combination of RcaC abundance changes and modification of RcaC by phosphorylation may be necessary to provide the dynamic range required for transcriptional control of RcaC-regulated genes.

Paper is the main print material, whose performance is a factor that effects the printing’s dot gain which is bad to image clarity and color reproduction. In the paper, Yule-Nielsen neugebauer spectral modal is analyzed , and the relation between paper’s spectral reflectance and the printing’s dot gain is discussed. By experiments, the paper’s spectral reflectance is adopted as correction index, which can reduce the dot gain value of the light color patch , and in the same printing conditions the dot gain is effected by the paper’s spectral reflectance, ink’s type, dot area percentage and wavelengths. The research has a certain significance for controlling printing quality and reducing the producing cost.
