The sophisticated colors of medieval glasses arise from their transition metal (TM) impurities and capture information about ancient glassmaking techniques. Beyond the glass chemical composition, the TM redox is also a key factor in the glass color, but its quantification without any sampling is a challenge. We report a combination of nondestructive and noninvasive quantitative analyses of the ...

BACKGROUND Permanent slide preparation of nematodes especially small ones is time consuming, difficult and they become scarious margins. Regarding this problem, a modified double glass mounting method was developed and compared with classic method. METHODS A total of 209 nematode samples from human and animal origin were fixed and stained with Formaldehyde Alcohol Azocarmine Lactophenol (FAAL...

The work presented in this paper is part of a wider research project, which aims at documenting and analyzing stained glass windows by means hyperspectral imaging. This technique shares some similarities with UV-VIS-IR spectroscopy, as they both provide spectral information; however, imaging has the additional advantage providing spatial information, since spectrum can be collected each pixel i...

Katarzyna Pyka discusses lead as a substance which for centuries has made possible stained glass glazing both in sacral and secular buildings. This article focuses on the uses of compares work artists past today. Contrary associations this craft with vivid multicolored compositions, decided to keep her discussion grayscale; purpose been emphasize importance silvery metal, enriched history art f...

The fate of the circumferential bundle of microtubules in activated platelets has been a subject of disagreement. Thin sections of stimulated platelets fixed at multiple intervals following exposure to aggregating agents have revealed that the circumferential band is constricted into a tight ring around centrally concentrated organelles. However, studies of detergent-resistant platelet cytoskel...

Developmental stages of Meloidogyne javanica were successfully released from roots by treatment with commercially available cellulase and pectinase. The average percentage recovery of nematode developmental stages from Dolichos lablab, Elymus glaucus, and Lycopersicon esculentum were as follows: eggs = 526%, J2 = 272%, J3 = 783%, J4 = 549%, adult females = 285%, and total = 425%, expressed as p...

A method was developed for extracting cryptosporidial DNA from stained fecal smears on glass microscope slides. The correct genotype of Cryptosporidium parvum was amplified by PCR from 89 (85%) of 105 smears following conventional staining but not from negative controls. This technique may have applications for analysis of other infectious agents.

Problem statement. These days, the issue of reducing energy consumption is relevant, including due to roof overhang formation in winter, when sun below horizon and can use solar heat for heating, summer, rises high above radiation maximum. The overhangs value therefore becomes relevant consumption. purpose article determine rational reduce dependence between stained-glass system height using Re...

In this paper, we propose a method for restoration of images stained with waterdrops on a protection glass surface. The method detects positions of waterdrops in images by comparing disparities measured from stereo images with the value calculated from a geometrical relationship of the glass surface and the cameras. Next, it estimates disparities of image regions hidden by waterdrops, based on ...
