The fine structure of pyrenoids from Chlorella pyrenoidosa shows a crystalline matrix with an 8-o-nm periodicity. In certain areas of the pyrenoid 2 sets of parallel lines intersect at approximately 8o° to give a criss-crossed appearance to the matrix. The recognition of the crystalline structure depends on the portion of the pyrenoid that is sectioned, as well as the plane of sectioning. A dis...

We define regular Kac-Moody superalgebras and classify them using integrable modules. We give conditions for irreducible highest weight modules of regular Kac-Moody superalgebras to be integrable. This paper is a major part of the proof for the classification of finite-growth contragredient Lie superalgebras. The results of this paper are a crucial part of the proof for the classification of co...

Spherical MgO nanoparticles and Flake-like clay minerals modified with polyaniline (PAni) are applied in Matrimid in order to fabricate mixed matrix membranes (MMMs) having improved gas separation performance. The CO2 permeability, CO2/CH4 selectivity and CO2-induced plasticization pressure of MMMs are assessed at 4-30 bar feed pressure. The chemical structure, morphology and thermal properties...

the purpose of this study was to examine how four teachers used the seven processes of videotape analysis to develop an analytic approach and reflective thinking towards their teaching. the study was organized within video clubs and was used to describe the interactions among four teachers about their experiences at a language institute. data were gathered through videotaped recordings of lesso...

We derive the effective permeability and permittivity of a nanostructured metallic photonic crystal by analysing the complex reflection and transmission coefficients for slabs of various thicknesses. These quantities were calculated using the transfer matrix method. Our results indicate that these structures could be used to realize a negative effective permeability, at least up to infrared fre...

 In view of the fact that pre-service teachers’ critical reflection through evaluating teaching activity of their peers is an important part of practicum activity, the current study aimed to analyze the recall and reflection journals written by pre-service teachers to identify and evaluate the discoursal features of their journals. To this end, a total of 272 recall and reflection journals writ...

We present a method to accomplish photorealistic rendering of real-world objects from their sparsely sampled appearance variation. Using a 3D model and a small set of images of an object, we recover all the necessary photometric information for subsequent rendering from arbitrary viewpoints and under novel lighting conditions. We first extract the diffuse reflection component from the input ima...

introduction: reflection is considered as a critical characteristic in professional competitions. despite propagation of reflection as an important educational issue and existence of several helpful patterns, instructions conducted by teachers to explaining and expanding of it, are very little. studies related to this topic were mainly performed in the field of nursing. therefore, we decided to...

The space of the random events Ω will be supposed a space of sequences of finitely many symbols ω = {ωj}j=−∞, for instance a sequence of spins ωj = ±1, with the usual metric d(ω,ω) = ∑ j |ωj − ω j|2, and with τ the shift to the left: (τω)j = ωj+1. A “reflection” operation will be defined on Ω as ω←→ωT , with (ω )j = ω−j. The probability distribution P will be a τ–invariant and reflection–invari...
