Alternative approaches for Preparation of AlN Nanolayers by Atomic Layer Deposition
Dallaev, Rashid ; Krčma, František (referee) ; Kolařík, Vladimír (referee) ; Sedlák, Petr (advisor)
Nitrid hliníku (AlN) je slibný polovodivý materiál s velkou mezerou v pásu. Tenké filmy AlN nacházejí uplatnění v různých elektronických a optoelektronických zařízeních. V první řadě je cílem výzkumu prezentovaného v rámci této disertační práce představit nové prekurzory do procesu ALD pro depozici tenkých vrstev AlN. Navrhované prekurzory jsou lepší než tradiční prekurzory buď v nákladové efektivnosti nebo reaktivitě. Část disertační práce je věnována prohloubení porozumění chemickým procesům, které probíhají během a po depozici. V tomto ohledu bylo navrženo pracovní řešení ke zlepšení chemického složení výsledných filmů a ke zmírnění nedostatků, například oxidace. Dalším důležitým aspektem této studie je důkladná analýza fenoménu vodíku v tenkých vrstvách AlN ALD. Vodíkové nečistoty byly zkoumány pomocí přesných a pokročilých technik patřících do skupin analýzy iontovým paprskem (IBA).

Growth of the Czech breastfed children at the age of 0-12 months
Riedlová, Jitka ; Schneidrová, Dagmar (advisor) ; Hrstková, Hana (referee) ; Sedlak, Petr (referee)
In the last decade, there is a growing focus of health professionals on growth of children and their mode of feeding in the early age. According to the WHO global public health recommendation, infants should be exclusively breastfed for the first six months and thereafter should receive nutritionally adequate and safe complementary foods while breastfeeding continues up to two years or beyond. In 2006, the WHO published growth standards and recommended their using for the assessment of growth of children up to the age of 5 years. The Czech Republic has a long-term tradition of its own nation-wide anthropological surveys (CAS) which provide data for constructing reference growth charts to be used for evaluation of growth and thriving in children. Therefore, the WHO growth standards were not implemented automatically. First, the study on growth of Czech infants exclusively or predominantly breastfed for at least 4 months (n=960) was undertaken. The aim of the study was to evaluate whether Czech growth references or WHO growth standards are more appropriate for growth assessment of Czech children. The study monitored four basic body parameters - length, head circumference, weight and weight to length. The hypothesis that growth curves of Czech breastfed infants will correspond to the WHO growth...

Variants Of Possible Penetrations Of Municipalities By Pv Sources
Sedlák, Petr
The study deals with the probable variants of penetration of municipalities by photovoltaic sources. It describes the current situation in the selected municipality in terms of photovoltaic power plants and considers possible alternatives for photovoltaic penetration. Probable option for penetrating photovoltaic sources in the municipality is determined.

Development of vital lung capacity in children
Navrátilová, Nela ; Sedlak, Petr (advisor) ; Novák, Jan (referee)
Deficiency of physical activity can negatively affect the functional and morphological development of an individual. This bachelor thesis provides a basic overview of the anatomy of the respiratory system and the development of the lungs in the prenatal and postnatal period. It also follows up the development of lung function in children and the factors that influence this development. The parameters of the greatest informative value from the point of view of morphological and consequently also functional differentiation of the lungs are forced expiratory volume in t second, forced vital capacity and Tiffeneau-Pinelli index. These parameters of lung function are used by most studies that have evaluated the relationship between their level of development and the child's physical activity. The effect of physical activity on the development of lung function was recorded mainly in the pubertal and prepubertal periods. The health condition of the child is also limiting for the proper development of lung functions. Different values compared to healthy individuals occur, for example, in individuals with cystic fibrosis or asthma. Key words: Vital capacity of the lungs; spirometry; physical activity

Design of communication network at a company headquarter
Kohoutek, Jan ; Sedlák, Petr (referee) ; Novotný, Vít (advisor)
The bachelor's thesis focuses on the design of a communication infrastructure project for a company building. There are production, storage and administrative premises, including Open Office space for rent. The basic documents for the work are the requirements of the investor and the floor plans of individual parts of the building. The result is an analysis, a proposal for the selection of individual components of the communication infrastructure, project documentation and, at the very end, an economic evaluation.
