On the cutting performace of selected process fluids in the MQL application
Pazdera, Lukáš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
Práce se zabývá mazáním za použití minimálního množství maziva, tzv. MQL. Cílem práce je experimentálně porovnat řezivost 4 různých řezných olejů. Oleje se v práci nazývají A, B, C a D, protože z důvodu utajení nemohou být zveřejněny jejich skutečné označení. Řezivost olejů bude testována při ortogonálním řezání na soustruhu a vrtání. Pro oba druhy operací budou použity 2 obráběné materiály: Korozivzdorná ocel AISI 316L a hliníková slitina EN-AW 7020. Měřené parametry během pokusů budou řezné síly, maximální teplota a drsnost obrobeného povrchu. Experimentální části předchází část teoretická. V této část jsou shrnuty poznatky týkající se problematiky procesních kapalin, aplikace MQL při obrábění, ortogonálního řezání, vrtání zmíněných materiálů a měření sil a teploty.

High Speed Milling of Aluminum Alloys for Aircraft Industry
Pazdera, Lukáš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The aim of this paper is a complex analysis of the high speed cutting in the aircraft industry. The paper studies especially the machining of aluminum alloys, which are characterized in the first part. We can find in next chapters a view on the high speed cutting from aspect of the chip formation, the force load and the machined surface roughness. The end of the paper is focused on the issues of the CNC, machining of typical aircraft shapes and description of roughing paths, which increase the productivity.

Reproductive senescence in female barn swallows (Hirundo rustica): age-related changes in components of reproductive success
Pazdera, Lukáš ; Tomášek, Oldřich (advisor) ; Riegert, Jan (referee)
The effect of age on an individual's fitness is one of the key topics of evolution ecology. Currently intensively studied manifestation of age is an aging of organism, thus a deterioration of metabolic functions and condition with age. An increasing count of studies shows that aging in the wild is rather a rule than exception, even with short-lived species of which the aging has not been previously presumed at all. Despite an increasing interest of evolution ecologists in this matter, some important aspects remain overlooked. Senescence of the traits are usually studied separately, therefore, an information whether an individual traits show similar or different aging dynamics is missing. The information is needed to assess if the signs are aging synchronously, as predicted by the William's antagonistic pleiotropy theory, or rather asynchronously. The suitable traits for study are these, which are involved in a reproduction activity. The reproduction is a sequential process consisting of many components, e.g. an expression of sexual ornaments (attractivity), nesting timing, amount of eggs laid and their size, etc. There is currently a little knowledge of which of these reproduction components are affected by the aging the most, and which are resistant to the the effect of age. Well studied is...

Physiological adaptations associated with body size and longevity in endothermic vertebrates
Pazdera, Lukáš ; Tomášek, Oldřich (advisor) ; Blažek, Radim (referee)
Abstact Lifespan is related to a number of physiological processes that are interconnected. Longevous species are assumed to have evolved certain physiological adaptations that slow down ageing rate and enable long lifespan. The aim of my thesis was to review physiological traits that has been hypothesised to be associated with lifespan, and to evaluate the empirical support for such hypotheses. Studies testing the association of these traits with body size has also been included in my thesis, as body size is known to be tightly related to lifespan. Traits that are reviewed in my thesis due to their hypothesised coevolution with lifespan are as follows: metabolic rate (i.e., a total amount of energy expended by the organism per unit of body mass and unit of time), oxidative stress resistance, telomere length and rate of telomere shortening and intensity of stress and immune responses. Key words: Lifespan, longevity, survival, reproduction, oxidative stress, free radicals, reactive oxygen and nitrogen species, metabnolic rate, immunity, antioxidants
