CSI effect and its influence on the perception of forensic biology
Míková, Zuzana ; Pinkr, Tomáš (advisor) ; Ehler, Edvard (referee)
1 Abstract This bachelor thesis tries to give an outline on how the TV projects into our everyday life. There are many crime TV series that we can watch. These programmes unfortunately give a distorted view of the forensic and investigative work performed in crime laboratories, as they show a great number of inaccurate or altogether false information. This thesis shows some cases of the 'CSI effect', which emerged after crime series got increasingly popular both in the Czech Republic and abroad. Then it explains how the so often used DNA analysis really works. Finally, it gives some ideas and examples of what teachers can do to prevent the CSI effect from spreading. Key word CSI effect, biological materials, DNA analysis, inquiry based science education

Nondestructive determination of nitrogen in biological and other materials by photon activation analysis
Krausová, Ivana ; Mizera, Jiří ; Chvátil, David ; Krist, Pavel ; Řanda, Zdeněk ; Kučera, Jan ; Štursa, Jan
A procedure has been developed for assaying nitrogen in biological materials by means of instrumental photon activation analysis (IPAA). The determination has been based on counting of the non-specific 511 keV annihilation gamma rays of 13N, product of the photonuclear reaction 14N(γ, n)13N and a pure positron emitter. IPAA allowed determination of nitrogen down to 1 wt.%. in selected biological reference standards - NIST RM 8433 Corn Bran, 1547 Peach Leaves, 8414 Bovine Muscle, and 1577b Bovine Liver. The optimized procedure was applied also to assaying nitrogen in pulverized nanodiamond intended for medical purposes.

The study presents a procedure for assaying nitrogen in biologocial materials by means of instrumental photon activation analysis (IPAA). The determination has been based on counting of the non-specific 511 keV annihilation gamma rays of 13N, product of the photonuclear reaction 14N(γ, n)13N, which is a pure positron emitter.
