Shade effect on the Coffea canephora diameter increment in the Mondulkiri province, Cambodia
Garcia Cano, Yessika Alejandra
Agroforestry systems with Coffee are very frequent, and, ecological benefits for the soil, water conservation, biodiversity, and quality have been well documented. It was hypothesized that shade practices might have influence on growth of C. canephora, therefore the increment of coffee shrubs and its relationship with environmental condi-tions like air humidity, temperature and soil moisture were studied. Three different Cof-fee plots in the province of Mondulkiri were selected. From the results, the statistical significance of the differences between the two main conditions, shade and full-sun was not clear, however it was assumed that other conditions besides microclimatic can have influence, like phenological stages of the coffee plant and source-sink relationships. Soil moisture remained higher under shaded conditions.

Fyziologické aspekty vegetativního množení dřevin řízkováním
Kohoutková, Petra
My work deals with physiological aspects of vegetative multiplication of species through section. On the basis of reading and studying of twenty-one specialised publications and thirteen electronic articles I tried to describe the core of impacts influencing the plants. I was concerned with stress factors, ways of multiplication of plants and using of growth stimulants. In my work I especially focus on the best way of multiplication of plants through section and on function of phytohormones on cuttings. Plants can influence production of stress factors impacting their progression.

The function of ClpX chaperone in bacteria
Kýr, Jan ; Balíková Novotná, Gabriela (advisor) ; Šiková, Michaela (referee)
Intracellular proteolysis is an essential regulatory process that affects cellular physiology. Since proteolysis destroys proteins irreversibly, this process must be strictly controlled. The AAA+ proteins are the key factors in regulated proteolysis in bacteria. These proteins consist of two functional domains, the AAA+ chaperone domain and the protease domain. One particular group of these AAA+ protein is the Clp protein family. Functional domains of the Clp family are formed by seperate proteins. The hexameric unfoldase ClpX is a member of this protein family. This unfoldase can interact with the highly conserved ClpP protease to form a ClpXP proteolytic complex. This proteolytic complex utilizes the energy of ATP binding and hydrolysis to unfold and translocate the specifically tagged substrate into the ClpP degradation chamber. Substrate recognition is mediated by the binding of ClpX to short unstructured sequences called degradation tags. ClpX recognizes several degradation tags, but the most important one is recognition of the ssrA degradation tag, which is the output of the tmRNA ribosome rescue system. Although ClpX interacts with ClpP, it affects a variety of cellular processes such as the expression of virulence factors or the adaptation to stress factors, ClpX can work independently of...

Physiology of Blood Brain Barrier
Kellner, Patrik ; Otáhal, Jakub (advisor) ; Pačesová, Dominika (referee)
This thesis takes on the theme of blood-brain barrier. Blood-brain barrier is a physiological barrier, that divides the circulatory system from brain, in place of their konfrontation. Barriers main task is to maintain homeostasis and regulate the transport of substances in both directions. The most important group of proteins, responsible for transport, are the ABC transporters. Alterations of barrier properties during the pathological states, but also the distribution of medical drugs is subject of futher investigations. Overview of the above mentioned themes will be mediated by this thesis.

Modelica in physiological modelling. Models with spatially distributed parameters, Authorin educational simulators.
Šilar, Jan ; Kofránek, Jiří (advisor) ; Maršálek, Petr (referee) ; Roubík, Karel (referee)
Mathematical models in physiology are useful to formulate and verify hypotheses, to make predictions, to estimate hidden parameters and in education. This thesis deals with modelling in physiology using the Modelica language. New methods for model implementation and simulator production were developed. Modelica is an open standard equation-based object-oriented language for modelling complex systems. It is highly convenient in physiology modelling due to its ability to describe extensive models in a lucid hierarchical way. The models are described by algebraic, ordinary differential and discrete equations. Partial differential equations are not supported by the Modelica standard yet. The thesis focuses on two main topics: 1) modelling of systems described by partial differential equations in Modelica 2) production of web-based e-learning simulators driven by models implemented in Modelica. A Modelica language extension called PDEModelica1 for 1-dimensional partial differential equations was designed (based on a previous extension). The OpenModelica modelling tool was extended to support PDEModelica1 using the method of lines. A model of countercurrent heat exchange between the artery and vein in a leg of a bird standing in water was implemented using PDEModelica1 to prove its usability. The...

The utilization of tensiomyograph for measuring muscle imbalances of men in artistic gymnastics
Duba, Jiří ; Šteffl, Michal (advisor) ; Krištofič, Jaroslav (referee)
Title: The utilization of tensiomyograph for measuring muscle imbalances of men in artistic gymnastics. Objectives: The goal of the study is through utilization of tensiomyograph determinate commonly occuring phenomenona in musculoskeletal system in mens artistic gymnastics. Methods: This is a pilot study. Data were collected with tensiomyograph. Research was done through qualitative mapping of 10 probands. Five muscles on the upper part of the body were measured on each side - 10 muscles total. Results: Percentage if recommended activities is as follows: 39% of stretching exercises, 26% of activation exercises, 3% of strength exercises. Muscles with standard physiological properties account for 32% of the whole representation Total lateral symmetry of each muscle is in the range of 6.4%. The highest lateral symmetry was achieved by the muscle biceps brachii with 86.5% and the lowest latissmus dorsi with 80.1%. The right and left elbows have an average functional lateral symmetry with 75% right elbow and 78.1% left elbow. Keywords: tensiomyograf, artistic gymnastics, physiology, lateral symmetry

Comparison of selected fitness assumptions for hockey players, footballers and floorball players of local level\\
NOVÁK, Matěj
The topic of this bachelor thesis is the comparison of selected fitness assumptions for ice hockey players, footballers and floorball players of local level. In this thesis we characterized selected sport disciplines from the physiological perspective. Further thesis is focused on the elements, which is needed to understand the movement and its metabolic pages. The end of the theoretical part is dedicated to the movement abilities and the testing in sport. In the practical part are included tasks and hypotheses of this thesis together with the aim of the thesis. Then, there is described the test battery, which was used for testing. Futhermore, in the practical part are described the characteristics of the test file, the methods of processing results, the results and their comparation. At the end of this thesis are presented the discussion and the conclusion.
