Polyurethanový (PUR) materiál (převážně pěnový) představuje svým podílem významnou složku plastového odpadu z autovraků. Na rozdíl od ostatních polymerních materiálů lze měkkou PUR pěnu snadno separovat z autovraků, neboť autosedačky zde tvoří relativně velké a snadno demontovatelné dílce o minimální kontaminaci. Z vyřazených automobilů lze demontovat cca 72 % z celkového množství odpadních PUR. Recyklace se tedy jeví jako vhodné řešení jak z pohledu ekonomického tak technologického. V druhém roce řešení projektu byl otestován recyklát získaný glykolýzou odpadní měkké PUR pěny při přípravě tvrdých PUR pěn, dále byla odzkoušena glykolýza odpadních PUR pěn z autosedaček po skončení životnosti automobilů a získaný recyklát byl opět testován jako surovina pro přípravu tvrdých izolačních PUR pěn. V druhé polovině roku byla studována především aminoalkoholýza jako další potenciálně vhodná metoda pro chemickou recyklaci měkké PUR pěny a získaný recyklát byl opět aplikován jako výchozí surovina pro přípravu tvrdé PUR pěny. V závěru roku byla proveden detailní souhrn možných analytických metod a charakterizovány vzniklé recykláty.
Hip Hop as a Culture Style, its Specifications and Influence on Teenagers
POSPÍŠIL, Jan
This thesis involves history of hip hop, its specifics and elements, it talks about influence of hip hip subculture on teenagers and points to positive and negative aspects connected to this culture style. In this way is work sectionalized into chapters. First part talks about history of hip hop, connection between religion and hip hop and also about Czech hip hop. Second part specifies on main elements of hip hop culture as DJing, MCing, breakdance, beatbox and graffiti. Last part focuses on influence of hip hop culture on teenagers, where is evaluated information about infuence of music and hip hop in general. Material was obtained by surveys from students attending four czech grammar schools.
Impact of weathering on chemical and morphological changes in stabilized polymers
Pospíšil, Jan ; Pilař, Jan ; Billingham, N. C. ; Marek, Antonín ; Kruliš, Zdeněk ; Nešpůrek, Stanislav ; Habicher, W. D.
Photooxidation, considered as the principal component of natural and accelerated weathering, affects together with oxygen,oxidizing and acid atmospheric pollutants durability of stabilized polymers by changing their chemical and supramolecular structure and influencing efficiency of stabilizers. Effects of the harshness of accelerated photooxidation, negative influences of atmospheric pollutants, heterogeneity in polymer oxidation together with formation of concentration gradients in stabilizer consumption and spatial distribution of stabilizer sacrificial transformation products are outlined. The data give more information on processes accompanying testing of stabilizer polymers and help to minimize misleading influences from over-accelerated tests.
Chemical transformations of poly[methyl(phenyl)silylene] under weatherometer exposure
Meszároš, Oto ; Schmidt, Pavel ; Pospíšil, Jan ; Nešpůrek, Stanislav
Specific behavior of poly[methyl(phenyl)-silanediyl] upon photooxidation in Weathermeter ATLAS was monitored during FTIR spectroscopy. Photooxidation results in healing of Si-Si conjugation and formation of siloxane species.
Using microformats in internet magazine development
Pospíšil, Jan ; Chudán, David (advisor) ; Nemrava, Jan (referee)
The aim of this work is to provide a look in a problem of semantics on the web, to implement the chosen semantic components (microformats and HTML 5) to the new version of internet magazine mobilenet.cz development and to make a research of microformats utilization by the competitive magazines and open source content management systems. This work shows the practical view in the microformats implementation into the system of the internet magazine, describes the implementation problems as well as their solutions. It also shows a review of real world usages and benefits, which these technologies provides. The utilization research also brings a look in the actual situation and the way of utilization on the Czech internet and provides valuable perspective of possible competitive advantages for the magazine too. It is also researched which solutions provide the open source content management systems. The work is divided into four chapters. First theoretic chapter deals with the semantics on the web, concretely with the microformats and HTML 5, followed by the basic description of the magazine's development and semantic components' implementation in chapter three. The last chapter is finally dedicated to the research itself.
Determination value of company ELMO, spol. s r.o.
Pospíšil, Jan ; Scholleová, Hana (advisor) ; Pospíšilová, Zuzana (referee)
The basic objective of the submitted thesis "Determination value of company ELMO, spol. s r.o." is exactly estimate the market value of ELMO company. Principle of this thesis states the summary and description of the incoming methods of company assessing. The analytic section of this thesis contains all information relating to above mentioned company. Further the financial and assessement analysis is performed and on its basis the financial plan is created. In next step the incoming methods are applied. The verdict of appraisal value is stated in the final section.
