Textbooks History of art culture for art and handicraft of secondary vocational schools: didactic analysis of texts
The thesis "School Textbooks of History of Visual Culture for Secondary Art Schools (Didactic analysis of texts)" is focused on the area of visual culture textbooks for professional secondary art education. The secondary art education in the territory of Czech Republic has a long tradition since the middle of 19th century and art history tuition realized in the school subject History of Visual Culture presents a considerable part of professional training of future artists, artisans and craftsmen. The main aim of the school subject is providing students with a complex and systematically structured knowledge of visual culture evolution, art trends and tendencies from the very beginning until the present days. This knowledge will be essential theoretical background for students' professional activities in the field of visual creation. Powered by TCPDF (www.tcpdf.org
Size-Dependent Immunochromatographic Assay with Quantum Dot Nanobeads for Sensitive and Quantitative Detection of Ochratoxin A in Corn
Fluorescent microspheres
are a novel luminescent nanomaterial proposed
as an alternative probe to improve the detection sensitivity of competitive
immunochromatographic assay (ICA). Quantum dot nanobeads (QBs) possess
strong luminescence and resistance to matrix interference. Theoretically,
large-sized QBs exhibit stronger luminescent intensity than small-sized
QBs and are beneficial to ICA sensitivity. However, oversized QBs
may reduce the sensitivity of competitive ICA. Thus, the relationship
between the size and luminescent intensity of QBs and the competitive
ICA sensitivity must be elucidated. In this study, QBs of different
sizes (58, 124, 255, 365, and 598 nm) were synthesized. Ochratoxin
A (OTA) was selected as the model analyte for competitive ICA. The
effects of QB size on the detection performance of competitive ICA
were then evaluated. The cutoff limit of QB-ICA for naked eye detection
was used for qualitative analysis, and the half-maximal inhibitory
concentration (IC<sub>50</sub>) and LOD were employed for quantitative
analysis. Results indicated that 124 nm QBs used as labeling probes
for competitive ICA showed the optimal detection performance and the
lowest cutoff value of 5 ng/mL for qualitative detection and IC<sub>50</sub> (0.39 ng/mL) for quantitative detection. Similar to commercial
ELISA, QB<sub>124</sub>-ICA displayed good accuracy, specificity,
reproducibility, and practicability. In summary, 124 nm QBs can be
used as a new labeling probe for competitive ICA
