Potential Radioactive Hot Spots Induced by Radiation Accident Being Underway of Atypical Low Wind Meteorological Episodes
Pecha, Petr ; Tichý, Ondřej ; Pechová, E.
Hypothetical radioactivity release with potentially high variability of the source strength is examined. The interactions of the radioactive cloud with surface and atmospheric precipitation are studied and possible adverse consequences on the environment are estimated. The worst-case scenario is devised in two stages starting with a calm meteorological situation succeeded by wind. At the first stage, the discharges of radionuclides into the motionless ambient atmosphere are assumed. During several hours of this calm meteorological situation, a relatively significant level of radioactivity can be accumulated around the source. At the second stage, the calm is assumed to terminate and convective movement of the air immediately starts. The pack of accumulated radioactivity in the form of multiple Gaussian puffs is drifted by wind and pollution is disseminated over the terrain. The results demonstrate the significant transport of radioactivity even behind the protective zone of a nuclear facility (up to between 15 and 20 km). In the case of rain, the aerosols are heavily washed out and dangerous hot spots of the deposited radioactivity can surprisingly emerge even far from the original source of the pollution.

Influence hematological and biochemical parameters by different dogs.
Pechová, Eva ; Fučíková, Alena (advisor) ; Václav, Václav (referee)
The topic of this diploma work was to evaluate the hematological and biochemical indicators of various breeds of dogs. The aim of this work was to evaluate the blood samples taken
from 10 dogs and 10 bitches of various breeds and find out the dependency of values
in relation to their age, nutrition and sex. The samples were processed and evaluated from May to October 2015. The following was examined from the hematological indicators: RBC, HGB, HCT, MCV, WBC and a blood smear was made, from which a differential count
of leucocytes was made. Furthermore, the following biochemical indicators were examined: TP, GLU, CHOL and ATP. The literature research first focused on the basic components
of dog feed. Moreover, the hematological and biochemical indicators of blood as well as the methodology of the whole experiment were described. The results were processed with the aid of the RStudio program and the following basic statistical characteristics were counted: median, minimum, maximum and standard deviation. The ANOVA statistical method was used, in which the dependency of values among sex, age category and the type of feed fed
to the animals was determined. Furthermore, the values among the breeds were compared. From the differences observed among the breeds, there was an increase in red blood cells
in German Shepherds and Dobermans. Dobermans, Labrador Retrievers and German shepherd crossbreeds had increased values of ALT. Significant findings showed that there was an increase in the number of red blood cells and hematocrits in subjects fed with granulated feed as opposed to subjects with a combined diet. The difference was also observed for MCV between the genders.
Differences between the genders were found for ALT values. More data would be needed
to confirm the relationship to age. ALT values are dependent on the type of feed, where the values are higher in subjects fed with a completely granulated diet. The values of total protein increased in dogs with age. This trend is likely to be observed in bitches. For subjects fed a combined diet (granulated feed + home diet) an increase in the value of total protein was observed with age. For subjects fed granulated feed, this increase was not as significant.
