Microfluidic circuit
Zeman, Radek ; Zemanová, Lucie (referee) ; Rudolf, Pavel (advisor)
Microfluidics is a science dealing with flow of a very small amounts of fluids and is mainly connected with medicine and biochemistry. One of a main problem, which this science is facing, is a difficult mixing of fluids due to occurrence of laminar flows. This bachelor thesis contains a design of a microfluidic circuit with Staggered herringbone microfluidic mixer and subsequent implementation of the experiment according to the performed design.
Hydrokinetic turbines
Zrebný, Radim ; Zemanová, Lucie (referee) ; Rudolf, Pavel (advisor)
Bachelor thesis concerns about problematics of hydrokinetic turbines. First part briefly describes potential areas of utilization. Second chapter includes research of available technical solutions, its operation principles and characteristics, while the main distribution is according to the position of the axis of rotation. Following part describes basic principles of the flow theory and achievable limits of energy conversion. Last part deals with design of hydrokinetic turbine used in paper production. The design has been estimated via Blade Element Theory.
CFD simulation of centrifugal pump working as a turbine (PaT) - influence of impeller side wall gaps on simulation results
Tomšej, Radek ; Zemanová, Lucie (referee) ; Štefan, David (advisor)
This master‘s thesis deals with a centrifugal pump running in reverse (turbine) mode, often called “pump-as-turbine”. The introduction lists basic principles and information about the direct (pump) and reverse modes. Several methodologies for predicting reverse operating point and efficiency evolution are used and compared with simulation results. Using CFD simulations, results obtained with simplified (excluding impeller side wall gaps) and complete geometry (including impeller side wall gaps) are assessed. Furthermore, the results of impeller trimming are evaluated with an aim to find the maximum power and efficiency. Impeller side wall gaps effect is analyzed in terms of friction torque and power loss.

Jindrová, Zdeňka ; Smetáčková, Irena (advisor) ; Zemanová, Lenka (referee)
Univerzita Karlova Pedagogická fakulta Katedra psychologie DIPLOMOVÁ PRÁCE Genderové vztahy mezi dívkami a chlapci ve smíšených třídních kolektivech na 1.stupni ZŠ Gender relations between boys and girls in mixed class groups in the first grade at elementary school Zdeňka Jindrová Vedoucí práce: doc. PhDr. Irena Smetáčková, Ph.D. Studijní program: Učitelství pro základní školy M7503 Studijní obor: 7503T047 Učitelství pro 1.stupeň ZŠ (OKM1STV06) Rok odevzdání: 2020 ABSTRACT My diploma thesis deals with the relations between boys and girls in two mixed class groups of a state primary school in the city "n" and two mixed class groups of a private primary school in the city "b". The work is divided into theoretical and empirical part. In the theoretical part I describe the basic definitions concerning the keywords of this work. I pay particular attention to the approach of individual pupils to gender issues and gender relations between pupils. I am interested in how good the relationships between girls and boys in mixed groups are. My work is based on professional literature, available Internet resources and the assigned questionnaires of relationships in the classroom. In the empirical part of the work I explain the methods and phases of my research. Questionnaires also serve as a decisive factor, if there is...
Didactics of Gifted Children at Primary School
Jůzová, Kateřina ; Krčmářová, Tereza (advisor) ; Zemanová, Lenka (referee)
This master thesis aims to describe the methods, form of work and educational strategies used in teaching gifted students and to verify their effectiveness in practice though action - based teacher research. The teoretical part contains the results of czech and foreign literature research concerning the issue of gifted education. It focuses mainly on methods, forms and content of education, but also defining the basic concepts of be gifted and be talented, models of giftedness, characteristics and typologies of gifted pupils, their motivation and attitude of teacher, who plays an essential role in the education process of (not only) gifted pupils. The practical part contains the course and evaluation of action teacher research, where I will apply theoretical knowledge to primary school classes with gifted children and verify their effectiveness in practice. The research is divided into two cycles. The first cycle is focused on observing teaching. The other one cycle includes the planning, implementation and reflection of self teaching, into which the theoretical knowledge is applied. The research results showed that the most of knowledge gained in theoretical part of the thesis was verified as effective. Especially creation of own materials, choice of interesting and actual topics. Key words:...
Time management of managers of small businesses
ZEMANOVÁ, Lenka
The purpose of this thesis is to analyse and evaluate time management of managers of small businesses and to propose optimal use of their time. Specifically, the thesis focuses on time management of managers of small businesses in the sector of communications and information services. The first part of the thesis focuses on theoretical description of 10 techniques, which are considered to be helpful in pursuing more effective time management. The next part of the thesis is practical and it is focused on the aim of the thesis. Two methods of analysis were used for this purpose. Firstly, it was questionnaire survey focused on analysis of basic characteristics of selected file's time management. Based on that, I was able to prepare an approximate proposal for making time management of this sample more effective. In order to develop a recommendation that will be tested in practice, the effectiveness of this proposal was examined through a second research method and thus in-depth interviews. Two detailed individual interviews with each respondent were carried out. In the first one, the specific situation of each of the respondents was analysed and the universal plan was adapted according to their individual needs and proposed to them. Managers followed the plan for few weeks and then gave me feedback on its effectiveness through a second in-depth interview. The final recommendation is divided into 2 sub-sections. All steps in the plan are covered in detail. The proposal contains visual example of righty scheduled day.
Developement of storytelling skills in preschoolers with the use of short film
ZEMANOVÁ, Lenka
Engaging and attractive media content is being exposed to young children since an early age. However, the impact of the media on their development is questionable. There are certain ways how to use media in order to have a positive impact on child's development If reasonable ways of handling media are found. Bachelor thesis addresses the use of digital media, film, in a nursery and aims to develop storytelling skills in preschoolers via the use of a short film. The study concludes, that there can be detected some improvements in storytelling skills of preschoolers by means of the program with the use of short films.
Tors and their microforms
Zemanová, Lucie ; Křížek, Marek (advisor) ; Vočadlová, Klára (referee)
This Bachelor thesis is focused on the general characteristics of tors and their microforms. There are two theories of tor's origin: one-stage origin and two-stage origin. Tors are developed all around the world, most often in temperate climatic zone. They show a wide range of sizes, shapes and locations. Tors are found on hill summits and on valley-sides. Tors occur on various lithologies, particularly on crystalline rocks. Many microforms can be found on the surface of tors. The most common microforms include weathering pits, tafoni, karren and honeycombs. The stage of their development enables microforms to be utilised for relative dating. Key words: tors, microforms, deep weathering, slope retreat
