Experimental Determination of Neutron Room Background at the NPI Cyclotron U-120M
Štefánik, M. ; Bém, Pavel ; Honusek, Milan ; Katovsky, K. ; Majerle, Mitja ; Novák, Jan ; Šimečková, Eva
During the operation of external neutron generators of the Nuclear Physics Institute of The Academy of Sciences of the Czech Republic, the neutron room background is produced in cyclotron hall. To assess this effect, the neutron room background was measured using the activation method of dosimetry foils. To unfold the background spectrum from the set of measured reaction rates, the method of spectrum description by the special analytical function was employed.

Story Alone against all (Beerman) / comiks/
NOVÁK, Jan
This dissertation consists of two parts, the theoretical one and the practical one. In the theoretical part, I pay attention first to the terminology of comic, the questions of what the comic actually is and what are the rules which form the genre. Next, I look into the usage of comic in the art lessons and what approach should the teacher take when teaching how to make a comic book or comic strip. In the next part, I consider, what knowledge should a cartoonist have when drawing a comic strip. I also explain methods which I have used when inking my comic book. In every chapter, I mention significant persons who influenced the world of comic either from the theoretical or the practical point of view. The practical part consists of collection of sketches, anatomical studies and comic strips, which have been inked by India ink and colorized in computer.

Radioactive wastes and the release of radioactive substances into the environment (learning program)
NOVÁK, Jan
This bachelor thesis, "Radioactive waste and the release of radioactive substances into the environment", is concerned (among others) with nuclear fuel and the biological effects of ionizing radiation. First, it briefly describes the history of this branch in the Czech Republic. Then the work is focused on the effects of ionizing radiation, divided into deterministic and stochastic effects. The work also contains a list of legislative norms regarding the handling of radioactive waste in the Czech Republic and the European Union. Protection of the environment and health against hazardous radioactive waste is at present regulated by several guidelines. The primary objective of this work was to compile a comprehensive basis for presentation to university students on the subject of radioactive waste and its impact on the environment. The concluding discussion presents the author's views on another possible application of e-learning in dealing with this branch of study at the University of South Bohemia.

The use of a shock wave in the physiotherapy
NOVÁK, Jan
Except a few scientific studies there is not yet enough available literature, written in Czech language, which would summarize theoretical information on the effects of shock wave therapy. In my thesis I tried to clarify physical conditions associated with emergence and specific spread of shock waves in various media and other physical principles which explain behavior and effects of shock waves passing through different types of tissues. From the results of expert studies and articles I made a survey of the most common possibilities of use of shock waves in medicine - especially in physiotherapy. In the practical part I evaluate the effects and course of shockwave therapy in three randomly selected patients diagnosed with epicondylitis radialis humeri (tennis elbow). Patients were treated by a series of applications of radial shock waves, when one session amounted to 1500 - 2000 shocks of varying frequency of 4-21 Hz and the pneumatic pressure of 2 - 3.2 bar. The results show that the patient may respond differently to shockwave therapy. Due to the fact that in a relatively small research sample quite disparate results have been recorded - the first patient significantly improved, the second improved slightly and the third got worse on the contrary - we can better understand the diversity of opinions of the professional public on the meaningfulness of the shock waves use in orthopedic diagnoses. For the practical part the method of qualitative research was chosen. Interview techniques, observations, case reports, data analysis and research were used. The research was conducted in the rehabilitation centre OLMA R + in České Budějovice and Rehabilitation Department of Polyclinic South MEDIPONT Ltd. in the time period from January to April 2012.

Study of photosynthetic response of green algae on presence of selected heavy metals
NOVÁK, Jan
With the world population growth, more and more agricultural areas fall into regions affected by waste products. Therefore it is important to determine their impact on environment toxicity. The aim of this thesis is to evaluate the effect of selected ions of heavy metals (CoSO4, CuSO4, CdSO4, ZnSO4 and K2Cr2O7) on the process of photosynthesis in a selected green algae species (Scenedesmus quadricauda) by means of monitoring of dynamics of oxygen release into solution of nutrient medium. The experiments with individual compounds proceeded by pH 7, temperature 25°C and light 450 ?mol m-2 s-1. Algareact device developed by the company BVT Technologies was used for measuring. Comparison with growth curves Scenedesmus quadricauda by different pH was used for the validation of the method. The method of the measurement of dissolved oxygen in medium is suitable for the measurement of immediate impact of chemical compounds on photosynthetic activity of examined organism. The method is restricted by the fluidity of measured solution. The lowest quantity of oxygen disolved inmedium was measured by CdSO4 in concentration 0,1 M.
