본 연구는 파프리카 육묘 시 다양한 LED 광질(red:blue = 10:0, 8:2, 2:8, white)에 따른 생육변화에 대하여 구명하여 수경재배용 묘 생산을 위한 전용육묘장의 기반기술로 활용하고자 수행하였다. 초장과 줄기직경의 생육은 red 비율이 높을수록 유의하게 길거나 굵었고, 엽면적은 red:blue 8:2에서 가장 넓었다. 건물 중량도 엽면적과 동일한 경향이었다. white에서는 모든 묘의 소질에서 다른 처리들보다 뚜렷하게 저조하였다. 상대생장률은 높은 경향을 나타내었고 순동화율은 blue 나타내었다. 따라서 시험에서 LED를 활용한 초장, 엽면적, 단위엽면적당 건물생산능력 등을 고려하였을 때 혼합광을 이용하는 것이 적합하고 특히, 8:2가 적합한 것으로 생각된다. 그리고 red와 파장의...

Some things about spider silk are difficult to understand.The genetic code for one of the more perplexing types of silk—the strands spiders use to weave their egg cases. Each case must be tough enough to keep out parasites, impermeable to rain and fungus, and breathable while insulating eggs from temperature extremes. These qualities alone would make an impressive fabric.The egg cases may even ...

Fusion-fission dynamics is investigated with a special emphasis on fusion reactions at low energy for which shell effects and pairing correlations can play a crucial role leading in particular to multi-modal fission. To follow the dynamical evolution of an excited and rotating nucleus we solve a 2dimensional Langevin equation taking explicitly light-particle evaporation into account. The confro...

We describe a novel interferometer design suitable for highly accurate measurement of wave-front aberrations over a wide range of wavelengths, from visible to x ray. The new design, based on the point diffraction interferometer, preserves the advantages of the conventional point diffraction interferometer but offers higher efficiency and improved accuracy through phase shifting. These qualities...

Conscious experiences are characterized by mental qualities, such as those involved in seeing red, feeling pain, or smelling cinnamon. The standard framework for modeling qualities represents them via points multidimensional spaces, where distances between inversely correspond to degrees of phenomenal similarity. This article argues that the is structurally inadequate and develops a new more po...

Computational representation of spatial qualities can lead us to a better understanding of how we construct spatial concepts. Analyses of spatial qualities can support architects in reasoning about the form of a configuration, helping them predict the consequences of a design. In this paper we present three definitions (enclosure, viewfield, continuity) that describe experiential qualities of a...

3D surface models are often stored as indexed face sets, whereas algorithms can typically treat only a subset of the so-representable surfaces. Besides this gap between “potential” input and “allowed” input, more and more algorithms specify their input requirements at a high level of abstraction (e.g. “natural” shapes), and this makes it difficult to automatically assess the appropriateness of ...
