Spirometrické měření studentů v závislosti na sportovní výkonosti / Spirometric Parameters of Students Depending on Their Physical Activity

Nedbalová, Jana January 2013 (has links)
The present work aims to answer questions regarding lung function among students of two types of grammar schools and describe selected indicators of differences between different groups of students within a reference population. The starting point for this work was speculation that the obligations defined by seconadary education in the ordinary type of school may significantly affect the students of the same age group and same Framework educational program for intensive regime of movement, breathing function. Is it possible that the secondary school educational program could affect the degree of respiratory function of students, for example by having less time and not having time for regular exercise? Are students of common type of grammar school physically less active than their peers from sports-oriented type of school? What are lung volumes of today's teens and how much do they differ from the current standards? The selection of respondents was elected from the students of sport-oriented grammar school and the common type of secondary school students. A total of 196 students participated in the study. Students were measured by spirometry lung capacity and function through painstaking cast in relation to strenuous breath. I have found that ordinary secondary school students have a positive...

Rybochovné a ekologické aspekty revitalizace rybníka Návežný, k.ú. Branišov u Dubného / Piscicultural and Environmental Aspects of the Revitalization of the Návežný Pond

ČERNÝ, Pavel January 2011 (has links)
The aim of this thesis was to document the various stages of restoration Návežný Pond ? ?Návesný? in the cadastral Branišov. The revitalization was used Operating Environment Programme, Priority Axis 6.4. - Optimization of the landscape. The hydrological parameters were monitored pond dredging, restoration of security overflow and bypass sewer. The revitalization was to increase the retention capacity of the pond using pond sediment extraction and subsequently by increased flood protection. Another important part of the revitalization is to restore the old defunct sewer bypass construction and safety overflow for the flood. Dredging is important to perform due to animal hygiene pond environment, biodiversity ecosystem pond, retention pond production capability and protection against floods. Due to the long-term return on investment is appropriate to use financial aid as grants. For the evaluation of most subsidies have been compared three grant degrees.

Využitie metódy Sur lie pri výrobe bielych vín

Bažalík, Michal January 2014 (has links)
Final thesis deals with research of exploitation of "sur lie" method in production of white wine. The focus is given on stability of wine, especially, stability against crystallization of tartrate salt acid in bottle, proteins stability and antioxidative nature of fine lees. First part of the thesis describes process of wine production by method of aging on fine lees. Composition of lees and cells of Sacharomyces cerevisiae together with its risks and benefits are illustrated in theoretical part. Experimental work monitored development of the wine stability in micro samples. The wine used for research purposes was variety of Silvánske zelené. Antioxidative capacity was monitored by FRAP method in the time of 16 weeks. Stability of proteins was measured by heat protein test and by turbidity meter. Content of tartrate salt was measured by filtration of samples and then weigh on laboratory scales. Sensory analysis was made by blind wine tasting degustation of professional commission. The results confirm higher protein stability which is about 30% more than in control sample. Risk of tartrate salt crystallization was reduced about 80 % in comparison with initial state. Antioxidative capacity of wine demonstrates slight decrease, but real required dose of SO2 added into wine was reduced. Key words: sur lie, bâtonnage, tartrate salt stabilty, antioxidative capacity, fine lees, mannoproteins, yeast cell, protein stability

Němeček, Martin January 2016 (has links)
Public transportation is important for urban development. It Must perform tasks interms of quality. Public transport services influencing many factors quality. For the transport company, it is important to define these factors and then these factors follow. Transport companies define standards of quality, their use offers a quality service that passengers expect. The character of public transportation and primarily functionality and efficiency greatly affect the quality of life of the population, respectively passengers. The goal of this taskis not only to analyze the current situation, but especially to suggest some optimization of the state, in the sense just to meet requirements and expectations of passengers. Finishing this optimization is conditional on economic efficiency, technical conditions and backgrounds, so they were within the proposed optimization takes into account these factors. Overall, in the context of optimizing it is a need to meet very specific groups of passengers, such as the elderly and children, as well as adjust the location and nearby bus stops and accessible by public transportation strategic points in the area (hospitals, schools, shopping centers). The task at least it draws attention to the major shortcomings in this sphere and the goal to propose possible solutions.
