In background study Design of Experiment methodology is described. Next part of background study describes the general principles of termography measurements, next chapter includes the information’s about LED technology and temperature degradation. At the beginning of the practical part is a description of the team analysis due to selection of factors, next chapter validates importance of vias. In next chapter methodology of print circuit board preparations and measuring are described. A next chapter describes the implementation of design of experiment at voltages 8 V, 13,5 V, 16,5 V. Designs of Experiments were made for four or five factors. The reason for this decision was the manual adjustment of printed circuit boards. At the end of each Design of Experiment is the recommendation of factors and interactions settings with regard on response, which is the minimal temperature. At the end of master’s thesis is the final evaluation.

Analýza strukturních elementů DNA / Analysis of DNA Structure Elements

Knytl, Marek January 2013 (has links)
The aim of this master's thesis is the design and implementation of tool trackAnalysis for statistical analysis of DNA structure elements. The positions of individual elements in genome are obtained in the form of the track, and with these positions the tool performs a set of analyzes, including randomness test of track, test examining distances between track and genes, detection of clusters and overlaps. The indivudual tests results can be linked together. The results will be displayed in the form of a list, a graph or a new annotation track. An important part of this thesis is also testing the resulting tool on a set of real data.

Kinetika příjmu hydrofobních organických látek v žížale Eisenia andrei v půdách s rozdílným obsahem organického uhlíku / Kinetics of hydrophobic organic compounds uptake in the earthworm Eisenia andrei in soils with different content of organic carbon

Šmídová, Klára January 2016 (has links)
This thesis is concerned with the fate of hydrophobic organic pollutants (HOCs) in soil. The theoretical part summarizes the current knowledge about bioavailability, factors influencing the bioavailability and methods for its measurement. Attention is paid to the organic carbon content, which is considered to be one of the key factors and to the influence of microorganisms that can degrade or interact with the substances, thus changing their bioavailable ratio. The practical part of the thesis uses bioaccumulation test with earthworm Eisenia andrei for evaluating the uptake kinetics HOCs in three soils with different organic carbon content. Soils were laboratory contaminated with mixtures of selected HOCs (phenanthrene, pyrene, lindane, p,p'-DDT and PCB 153) and the concentrations of substances in these soils were followed for 217 days. Subsequently, bioaccumulation test was conducted; earthworms were exposed from one to twenty-one days. The collected data were used to model uptake kinetics curves for individual substances. Peak-shaped bioaccumulation were found for pyrene, for lindane a steady-state concentration during exposure was observed, whereas for p,p'-DDT and PCB 153 growing concentrations after twenty days of exposure were detected. The reason for the different behavior of the substances was probably their diverse sorption on the organic material, which together with the different speed of elimination influenced final concentration in earthworms. Phenanthrene was not detected in some samples and therefore the modeling of uptake kinetics was not possible.

Pilotstudie zur Bedeutung von rekombinantem, aktiviertem Faktor VII in der Therapie von intraventrikulären Hirnblutungen bei Frühgeborenen

Ritter, Jenny 18 January 2017 (has links)
In dieser retrospektiven Pilotstudie zum Einsatz von rekombinatem, aktivierten Faktor VII bei Frühgeborenen (Schwangerschaftswoche < 32, Geburtsgewicht < 1750 g) mit intraventrikulären Hirnblutungen wurden anhand sonografischer Untersuchungen der Blutungsprogress sowie die Nebenwirkungen der Therapie im Vergleich zur Standarttherapie mit Fresh Frozen Plasma untersucht. Die Auswertung erfolgte in zwei Gruppen: innerhalb des Gesamtkollektives und innerhalb der Matching-Gruppe. Es zeigte sich in beiden Auswertungsgruppen ein signifikant geringerer Blutungsprogress in der Therapiegruppe. Außerdem konnte ein früherer Blutungsstopp in der Therapiegruppe nachgewiesen werden. Ein erhöhtes Nebenwirkungspotential von rekombinantem, aktivierten Faktor VII war in diesem Patientenkollektiv nicht eruierbar. Weiterführende prospektive, randomisierte, multizentische Studien zur Evaluation dieses vielversprechenden Therapieansatzes werden empfohlen.

Rekombinantní příprava transkripčního faktoru TEAD. / Recombinant preparation of TEAD transcription factor.

Lišková, Růžena January 2016 (has links)
Recombinant preparation of TEAD transcription factor (abstract) The TEAD family transcription factors play an important role during devolopment of organisms, where their main purpose is to regulate organ size by activating expression of proteins involved in cell growth and differentiation and apoptosis inhibition. TEAD proteins activity is regulated by signalling pathways and interactions with coactivators. Disregulation of these mechanisms can lead to development of tumors, which is the reason why TEAD proteins became an interesting target for development of new anticancer drugs based on inhibiting their activity. There are several possibilities how to inhibit activity of a transcription factor including blocking its bond to DNA. To design a new drug that blocks transcription factors binding to DNA the structural basis of interaction of these two molecules has to be known first. In this thesis the DNA binding domain of human protein TEAD1 was prepared using the technique of recombinant expression in bacteria E. coli. Suitable conditions of protein production were found and the DNA binding domain of TEAD1 protein was purified so it will be possible to use it for structural analysis of its intraction with DNA.
