The archeobotanical research of the Early Modern waterlogged cesspit in Prague-Celetná street and possibilities of photography documentation
IRMIŠOVÁ, Jitka
Based on the macroremains analysis from Early Modern waste filling of the well in Prague Celetná street, dietary habits of Prague dwellers and the character of the city environment from the second quarter of the 18th century to the early 20th century were constructed. In total 44 015 macroremains were found, of which only 2 707 diasporas were wild-growing species. Strong predominance of crop confirmed hypothesis of well-into-cesspit transformation at the end of the 18th century. The species such as Nicotiana rustica, Piper nigrum and Ocimum basilicum, not commonly occurring in the archeological objects were recorded. The changes of the diaspora external structure influenced by their long-term deposition under anaerobic conditions were examined by electron microscopy method. A difference in subtle damage to the distinct diaspora structure along with the rate of diaspora organic pollution was noted.

Physical principles of transmission and scanning electron microscopy
BÍLÝ, Tomáš
This bachelor thesis focuses on the description of transmission and scanning electron microscopy. It describes physical principles and defects arising during image formation in electron microscopes as well as the methodology of adjustment. The basic parts of electron microscopes are looked into more closely herein with consideration to the lectures. Practical implementation is demonstrated on following microscopes JEOL: JEM-1010, JSM-7401F, JDM-6300.
