Analysis of inward movement of inhabitants to work in development centers and choice of means of transport
Brůha, Jiří ; Pova, Patrik (advisor) ; Říhová, Gabriela (referee)
This paper analyzes the inward movement of inhabitants to work in the development centers. These centers are cities Brno and Karlovy Vary. At first this paper describes the chosen centers Brno and Karlovy Vary and districts where the centers are placed. Then this paper describes which one means of transport is the best for inward movement to one of the centers mentioned upwards. The means of transport are described from the prize angle and the time angle. Means of transport chosen for this paper are train, bus and car. Other means of transport or combination of means of transport was not coceded. Results from this analysis show, that the selection of the best means of transport is not single valued. It is because the best means of transport from the prize angle are not in all cases the best means of transport from the time angle.

Functional analysis of plant Arp2/3 complex subunits
Kukla, Jakub ; Schwarzerová, Kateřina (advisor) ; Honys, David (referee)
1. Abstract ARP2/3 complex is well studied in case of animals, it plays key roles in motility of cells and intracellular organels. It's malfunctions result in severe growth disorders and even lethality of affected cells. On the contrary, plant cells do not exhibit such dramatic phenotype of ARP2/3 complex mutations like it is by animals. It is possible that just the different life strategies of plants and animals contribute to differences in a way how animal and plant cells use their cytoskeleton, where ARP2/3 complex is it's part as well. It is highly conserved 7 protein complex from yeast to human. His main functions are creation of new "de novo" actin filaments, actin branched filaments network. Some of the parasite organisms are capable of missusing its nucleator activity to actively move inside of host cell. Because of the plant cells are sourounded by the cell wall, which give them support in creating various shapes and also hinders active movement of the whole cell body, it is likely that ARP 2/3 complex could be possibly involved in novel plant specific functions as well. If we think about the different life strategy of plants and animals we can not ignore all the things these two kingdoms have in common regarding to cytoskeleton processes. That is the need both for vesicular transport and...

Public transport route searching using moves afoot
Jiráček, Zbyněk ; Babilon, Robert (advisor) ; Foniok, Jan (referee)
Finding the fastest way between two given places is in recent hurried times quite useful thing. According to the complexity of traffic networks in larger cities a route searching engine becomes almost a necessity. Typical programs that focus on this problem usually do not pay attention to paths between individual stops and allow only movement in the scope of a single station. Many people, mostly those who do not know the area well enough, do not realize that in a city they can relatively quickly move by foot. Goal of this project is to design and implement a program which will be able to navigate user in the scope of a given city to a specified destination using means of public transport and walking. Instead of navigating only between stations, any place in map should be accepted.

Tree rings as a Pb pollution archive
Šimeček, Martin ; Mihaljevič, Martin (advisor) ; Strnad, Ladislav (referee)
The Bachelor's thesis is written as a research talking about storing Pb in tree rings. The first part speaks about the basic characteristic of the pollutant, his natural and anthropogenic deposits. Following chapters are comparing the tree rings with the peat bogs, which are often used as a natural archive of the contamination by the metallic elements. Than I continue with the description of the transport of Pb into wood and subsequent radial distribution in tree rings. One of the chapters concludes the results of certain researches of tree rings. The main time sections of environmental pollution in the 20th century are shown by the results of researches on the concentrations and isotope ratios of Pb. These studies informe us also about sources causing this pollution. The thesis includes also a chapter about bark pockets, which can be used as another alternative to observe the movement of Pb in the environment. The last part describes the method ICP-MS usually used to determine Pb in natural materials.

Simulation of saltation motion using LBE based methods
Dolanský, Jindřich
The numerical model of the motion of the circular particle close to the bed in an open channel with a rugged bed based on the lattice Boltzmann method (LBM) is presented. The LBM is used as a DNS approach in which hydrodynamic forces are expressed as sum of contributions from fluid elements interacting with the moving particle. The corresponding numerical simulation for the saltation motion which represents a dominant mode of the bed load transport is developed. Flow is driven by the logarithmic velocity profile at the inlet of a two dimensional channel with a bed formed by semi-circles of variable radii in a bed of particles. Translational and rotational movements of the particle are induced by gravitational force on one hand, and by hydrodynamic forces on the other hand. The LBE (lattice Boltzmann equation) based simulation provides the opportunity to study the behavior of saltation motion in the moderate and high Reynolds number regimes. Most of the input parameters, including boundary conditions or flow conditions, are adjustable within a range of values. Stability issues of the simulation are considered and a resolution using a combination of different LBE models and the extension of computational resources is proposed. Finally, an enhancement of the simulation for more complex processes is suggested.

Numerický 3D model kolize pevné částice s drsným dnem kanálu
Lukerchenko, Nikolay ; Chára, Zdeněk ; Vlasák, Pavel
The paper deals with 3D numerical model of the random process of rotating spherical particle-bed impact and rebound for saltation movement of a particle in channels with rough bed. The collision height and the contact point are defined as random variables of the collision process. The collision height depends on bed roughness. The contact point position depends on the irection of the particle velocity vector before the collision

The Conditions for Spontaneous Movement Activities for Children at the Lower Level of Primary School in a Housing Estate
Kratochvílová, Hana ; Hronzová, Marie (referee) ; Dvořáková, Hana (advisor)
The aim of this work was to find out and deseribe the conditions for spontaneous movement in the city and wether their needs and wishes are respected and wether the playgrounds correspond with the norms and the proposal of the specialist. The theoretical part deals with the role of the playground in children's lives, with creating of conditions for movement and with the influence on their helth. I have used seven different methods in my work: a questionnaire, a project method, an individual and group discussion with children, interviews with experts and architects, an analysis and controll of the conditions for movement, a systematic non-committed observation. I stated eight hypotheses to reach the individual partial goals. I supposed that transport attainablity of the playgrounds and sport grounds is within the reach of walking and means of transport. And that children prefer swimming and playing in wather to the games in the playgrounds, that children in the playgrounds miss the natural elements, that from all the elementa of play they will use the slide, the swing and the sand-pit and that this equipment will be considered as the elements which mustn't be absent. The result of the research isthe statement that the elements of play are in accordance with safety regulations ČSN and the demands of children...

Moisture and its transport in shallow subsurface of quartz sandstone
Svobodová, Eliška ; Bruthans, Jiří (advisor) ; Schweigstillová, Jana (referee)
The thesis deals with moisture transport in porous medium of quartz sandstone. Capillary water and its movement is crucial for processes such as salt and frost weathering, growth of organisms and development of honeycombs and tafone. However, moisture transport is still not well described. I focused particularly on two new methods applied to sandstone investigation. In the laboratory I studied moisture transport in sandstone samples by means of repeated injection of uranine solution. I observed the evolution of evaporation front based on the changes in solution concentration indicated by difference in color of uranine solution. Additionally I investigated moisture content in the shallow subsurface of sandstone outcrops in the field using suction pressure and moisture content measurements by microtensiometers and TDR in three locations in the Bohemian Cretaceous Basin. Uranine proved to be an excellent tracer for visualization of the evaporation front geometry and its evolution in time. The results suggest that moisture transport is considerably affected by the presence of biofilms which are hydrophobic and retain moisture transport to surface. In addition, the values of suction pressure measured in honeycombs and a tafone are in agreement with the salt weathering model proposed by Huinink et al. (2004).

The Patients´ Intimacy Problem during the Preoperating Preparation and the Transport to the Operating theatre on the Orthopaedic clinic.
FERENCZOVÁ, Romana
The bachelor thesis is specialized in the intimacy of the patients during pre-operative preparations and movement to the operating theatre in the orthopedic department. The thesis is also specialized in the nurses?s behavior which these activities are doing. The intimacy is still discussed topic. It is the conflict of the right of patient to privacy and the effort of medical staff members to the best pre-operative preparations and subsequent movement on the operating theatre. In spite of the big efforts of medical staff members there are the situations which cause the shyness and the shame of patients. The main reason is time pressure which is exerts on the medical staff members. The disruption of the intimacy can be caused by the wrong communication between the nurse and the patient but also between the staff themselves. Every patient is individuality and therefore there is not possible to set one standard working procedure which solves this situation. The main objective of this thesis was to find out how the intimacy of patients during pre-operative preparation is secured and to study possibilities of the ensuring intimacy during movement to the operating theatre. The next objective was to find out during which activities (performances) during pre-operative preparations the intimacy used to be frequently devastated. The data were obtained within qualitative research from two non-standard interviews. One type of interview was done with seven randomly chosen patients of the orthopedic department. The second one was done with seven nurses working in the medical facility. One of the nurses is working in the operating theatre. The nurses from the inpatient ward were asked if they respect the patient´s intimacy consistently than the nurses in the operating theatre. They were also asked if there is difference in observance of patient´s intimacy during pre-operative preparations in the scheduled operating performance and urgent performance. The objectives of the bachelor thesis were fulfilled. During interviews there was found out that the disruption of the intimacy was most often realized during movement to the operating theatre. The identified results will be provided to the management of the medical facility to create the standard for the securing of the patients intimacy on the operating theatre.
