METAPHORICAL COMPARISONS WITH THE COLOR STANDARD (BASED ON THE MATERIAL OF RUSSIAN LITERARY DISCOURSE)

Modern linguistic studies of cultural manifestations of different ethnic groups that found their place in the language prove that language affects how a person perceives the world around him or her. The language creates a naive picture of the world, which is based on popular wisdom and knowledge of cultural ethnic or universal human norms and traditions. This picture has its own unique laws, different from the scientific picture of the world, dictates its own categories of space and time, as well as color and function. This article presents a linguoculturological analysis of metaphorical comparisons with a color standard to identify regular metaphorization models, the frequency of choice of a particular comparison agent, which indicates a subject of thought that does not have a conventional color meaning in the language. This study focuses on metaphoric coloratives in Russian fiction of the 20th century. The metaphorical comparisons-coloratives were selected by continuous sampling in the amount of 275 units, while the analysis covered lexemes-agents. The results show that the main colors of figurative comparisons-coloratives of the literary discourse were yellow, red, white, black, brown, gray, green, and blue. A classification of reference color agents is compiled, containing seven semantic groups, which can be correlated with both agents and references comparison, which allows using the formula of the semantic comparison structure. As a result, the quantitative indicators of formulas for different coloratives were obtained, with phytomorphs being the most frequent standards of red, yellow, brown, blue, and green. The second place belongs to reamorphs, which are rich, but not the only source of black standards. Naturmorphs are in the third place; these are the suppliers of agents of black, as well as yellow and gray. They are followed by gluttomorphs, which are the leading white standards. Zoomorphs are uniformly present in almost all colors except brown and blue. A small number of anthropomorphs agents are red standards, and hemo­morphs agents are green standards.

Transmissive properties of Medieval and Renaissance stained glass in European churches

Medieval stained glass is often described by how its clarity contributes to the lightness or darkness of a sacred interior. Using high dynamic range (HDR) imagery (a low-budget, time-efficient means of photographic data collection) to estimate luminances (or per-pixel brightnesses), the relative transmissivities of adjacent panels of glass are obtained for the first time in a variety of medieval churches in western Europe. In order to carry out a comparison between different interiors, red glass was assumed to have a fixed average transmissivity, based on data that suggest that the glazing transmission of red panes is relatively constant. This red standard was then applied over a large database of images collected from different churches to provide a quantitative index of stained glass light transmission. The results indicate that the use of brighter colours during the 12th century admitted more light compared to 13th-century glass. Furthermore, the more translucent glasses of the 15th and 16th centuries appear to have increased light transmission into the interior by as much as an order of magnitude. The resulting change in indoor illumination significantly altered the human visual perception of the sacred interior as glazing preferences evolved over the course of the late Middle Ages.

Measurement of Porphobilinogen in Urine by a Simple Resin Method with Use of a Surrogate Standard

In this method for urinary porphobilinogen (PBG), urine is added to Bio-Rad AG1-X2 (200-400 mesh) acetate resin under alkaline conditions and mixed. After two water washes, the adsorbed PBG is eluted with acid and reacted with Ehrlich's reagent (p-dimethylaminobenzaldehyde). Quantification is by comparison of the color developed with that of a PBG standard similarly treated or of a calibrated methyl red solution. The precision of assay of PBG at 20 and 50 mumol/L is 1.4% and 0.9% within-batch and 4% and 3.9% between-batch, respectively. The analytical recovery is about 90%, a proportion that appears to be inherent in the resin method. The proposed method (y) agreed well with the method of Mauzerall and Granick (x; J Biol Chem 1956;19:435-46), yielding the regression equation y = 0.957x + 2.9 (r = 0.993, n = 26). Good agreement was achieved with results determined from the PBG and the methyl red standards. The proposed method is inexpensive, simple to perform, and suitable for routine and emergency use.
