Aerosol light extinction measurements
Múčková, Nikola ; Zíková, Naděžda (advisor) ; Holubová Šmejkalová, Adéla (referee)
This bachelor thesis deals with the basic processing of measured light extinction data, which was measured at seven wavelengths using the aethalometer (AE-31, Magee). Since 2012, the device has been located at the Košetice meteorological station in the Czech Republic, where the measurement has been ongoing and is currently continuing. The measured data from 2013 to 2015 were processed to provide a basis for further research in meteorology and climatology. Basic parameters such as extinction coefficient and other derived characteristics (Angstroem absorption coefficient, Delta-C) are calculated. From the final data the total average values and time dependencies are determined as daily, weekly and yearly cycles. All dependencies are graphically visualized and commented on. During the data processing, it was also found that during period 2013 - 2015 there was a decrease in the average of the concentration of black carbon and that it was the highest in the winter months. Keywords: atmospheric aerosol, light extinction, time series evaluation

Project management Support the teaching of pupils in gastronomy
Šmejkalová, Adéla ; Dlouhý, Martin (advisor) ; Borovička, Adam (referee)
The aim of this bachelor thesis is to evaluate the realised project "Endorsement of comprehensive, executive and practical teaching in gastronomy" using project management methods. The project is being realised by IREAS, Institute for Structural Policy and 12 schools from all over the Czech Republic participate in it. The project is being realised in cooperation with the Association of Chefs and Confectioners of the Czech Republic and by Jules and Jim. The project will be prepared using MS Project 2010. The thesis is divided into theoretical and practical part. The theoretical part describes basic concepts of project management and methods of project management. The practical part deals with the project itself, starting with the request for support to the actual implementation of the project. The necessary data for the evaluation of the progress and implementation of the project were provided by IREAS, Institute for Structural Policy with which I cooperate in the implementation of the project.

Monitoring the coefficient of light scattering on aerosol particles at the Kosetice background station
Holubová Šmejkalová, Adéla ; Zíková, Naděžda ; Ždímal, Vladimír ; Holoubek, Ivan
The direct effect of the atmospheric aerosols to radiation balance is the scattering or absorption of light on these particles. While solar radiation on aerosol particles or clouds negatively affects the radiation (resulting in cooling), absorbtion causes increasing of the ambient air temperature. Contribution to the study of the effect of aerosol particles on the climate, a measurement of the coefficient of light scattering is carry out at the Kosetice background station. The Integrating Nefelometer measures at 3-wavelength (RGB) forward and back light scattering. The values of the scattering coefficient at 550 nm (green) are typically high in the cold part of the year, reflecting both increased concentrations of pollutants and stable atmospheric conditions. Daily variability is the smallest in summer (varies between 25 and 18 Mm-1), the most noticeable daily variation is observed in the spring, when stable values 44 Mm-1 drop after noon to 26 Mm-1. The calculation of Ångström's exponent showed that in the summer, the fine fraction dominates in the sampled air.
