Design of outdoor solar shower
Dener, Lukáš ; Sládek, Josef (referee) ; Haltof, Vladimír (advisor)
The topic of this bachelor´s thesis is the design of an outdoor solar shower. The main goal of this work is to design and outdoor solar shower with an emphasis on functionality and practicality. Ecological and technical potentials that innovate existing products should be used in the work. The design is based on the current state of knowledge and was created with regard to ergonomic and technical requirements. The resulting product will find it´s use in owners of gardens, cottages and private lands, as well in public swimming pools or beaches.

no noon on
Janechová, Lucia ; Houser, Milan (referee) ; Štindlová, Marie (advisor)
The thesis focuses on the theme of sun. We perceive the sun in many different ways according to its position on the sky, to where we are located or simply depending on our current mood. In paintings and objects I look for ways to capture it's visual form or the imprints of feelings it's capable of creating. For that I use spiky or round branch-like shapes as the variations of the sun rays, in the centre of paintings is usually a circle. I combine acrylics and oil with dry pastel, which enable more relaxed and free strokes. In effort to expand the scale of medium I included materials like copper or concrete in my work. The series is therefore finished with relief almost-objects and a copper “gate” the sun figuratively passes through at noon.

The role of LINC complex in male germinal cells
Kmoníčková, Věra ; Komrsková, Kateřina (advisor) ; Knop, Filip (referee)
LINC (linker of the nucleoskeleton and cytoskeleton) complex is substantial for the overall function of any nuclear cell. It is a bridge between the cytoplasmic and nuclear structures which mediates transmission of mechanical forces generated on the cytoplasmic side. The main objective of this thesis is the function of distinct variants of the LINC complexes in mammalian male germinal cells throughout their development. The nuclear facing side of the LINC complex is a key player in homolog pairing and rapid chromosome movements during meiosis. The cytoplasmic facing side is necessary for the sperm head formation, proper acrosome and nucleus attachment. Evenly, another complex is essential for the head-to-tail coupling as without this one the sperm cells are found decapitated. If the subunits of the LINC complex are defective, males are afflicted with different kinds of infertilities, which nowadays is one of the important issues of our society. Many things about the role and structure of the LINC complex has been discovered due to modern technologies. These up to date findings are summarized and discussed on the following pages.

Calculation of orbit for Solar research satellite
Stopka, Jiří ; Daněk, Vladimír (referee) ; Bartoněk, Jaroslav (advisor)
The aim of this thesis is to propose a suitable methodology for finding orbits around the Earth in which it will be possible to create conditions for a total solar eclipse. The methodology for orbit determination is designed and implemented through a Pascal scripting language, which is included in this work. The resulting orbits obtained using the proposed methodology are mutually evaluated. The thesis also includes a discussion on the scope of applicability of this methodology.

Sun and its presentation within lessons at primary school
DROZENOVÁ, Barbora
My bachelor's thesis deals exclusively with the topic of the Sun and its presentation in primary school. The first half of the thesis is devoted to the stars, general information about the Sun (its meaning, distance, origin and evolution), the composition and structure of the Sun, its movements, solar activity, eclipses and research. This is followed by a section on the presentation of the Sun in the framework of the Primary and Secondary School Curricula of selected schools. The second part of the thesis is devoted to the analysis of textbooks, the opinions and form of teaching of the interviewed teachers, and above all to a questionnaire survey which deals with pupils' knowledge of this topic in selected schools.

The Sun in the first grade of elementary school
VÁŇOVÁ, Aneta
My master thesis deals with the Sun. The first part of the thesis is devoted to the stars, the origin of the Sun, its evolution and future, the structure of the Sun, the Sun's activities, its motion, its influence on the planet Earth, the magnetic field of the Sun, the exploration of the Sun and solar mythology. Last but not least, the RVP ZV and the ŠVP of selected schools are briefly discussed. The second part of the thesis is devoted to the research of the pupils' knowledge, the teaching of my sample lesson, the evaluation of the input and output questionnaires and the comparison of the results with each other.

LINC complex: The link between chromatin integrity and sperm motility
Šanovec, Ondřej ; Komrsková, Kateřina (advisor) ; Lánská, Eva (referee)
The LINC complex (Linker of the Nucleoskeleton and Cytoskeleton) is a protein structure located in the nuclear membrane that connects the cytoskeleton with the nucleoskeleton. This complex can be found in every mammalian cell including the gametes. However, here the LINC complex is more diverse and less studied than in the somatic cells. In this thesis, the LINC complex and its role in spermiogenesis have been studied in wild-type and Protamine 2 knockout (Prm2-/- ) mice. Protamines are small proteins that replace histones during spermiogenesis. The mouse model generated by the group of prof. Hubert Schorle has a deletion in Prm2 in exon 1 and its sperm possess a surprising phenotype including complete loss of motility. Therefore, it was hypothesized that the LINC complex might be responsible for miscommunication between the sperm head and tail which leads to the loss of sperm motility. Results from this study suggest that the LINC complex is not influenced by Prm2 deletion, however, actin dynamics, cytoskeletal motor proteins and tubulin acetylase/ histone deacetylase activity might be impaired. Prm2-/- sperm have a significantly higher abundance of β-actin compared to the wild type. Next, Prm2-/- sperm also show a different pattern of acetylation of α-tubulin but no change in the abundance of...
