Antibacterial electrospun membrane prepared from poly(vinylidene fluoride)-co-hexafluoropropylene with lauric acid monoacylglycerol
Zelenková, Jana ; Peer, Petra ; Pleva, P. ; Janalíková, M. ; Sedlaříková, J. ; Filip, Petr
The aim of this study was to prepare an antibacterial nanofibrous membrane using electrospinning technique. The nanofibrous membranes were spun from polymer solution of poly(vinylidne fluoride)-co-hexafluoropropylene (PVDF-co-HFP) dissolved in N,N´-dimethylformamide. Monoacylglycerol of lauric acid (MAG C12) was used as an antimicrobial agent at the concentrations ranging from 1 to 3 wt%. The impact of MAG C12 incorporation on the rheological, structural and antibacterial properties was investigated. The rheological tests of polymer solutions, as steady shear and oscillatory shear, proved that addition of MAG C12 changed marginally rheological quantities such as viscosity, elastic (storage) and viscous (loss) moduli. Measurement of mean nanofibres diameter indicated a slight decrease with increasing MAG C12 concentration. Antimicrobial activity of PVDF-co-HFP nanofibre membranes with incorporated MAG C12 against Gram-positive bacteria Staphylococcus aureus and Gram-negative Escherichia coli was studied. An antibacterial activity was revealed for the samples containing MAG C12 at all concentrations against Gram-positive bacteria Staphylococcus aureus by the disk diffusion method.
On-line communities
Pleva, Petr ; Kandert, Josef (advisor) ; Pospíšilová, Marie (referee)
Petr Pleva On-line communities Abstract The bachelor's thesis "On-line communities" deals with the topic of online communities and software that they use. The aim of this work is to reveal regularities in the development of these communities and find the influence of software on their lives. First, I deal with the term "online community" and its definition over the years. Based on the chosen literature the work identifies key elements of life of online communities. I highlight the purpose of emerging communities and the importance of technical platforms they use. The next part describes members of online communities, particularly the membership life cycle and the significance of identity. The work describes the types and value of special events for the life of community and also describes the most common types of software. The practical part of this thesis evaluates the results of observations in several online communities and analyzes them based on selected key factors. I find similarities in their develomplemt and based on them I determine three phases of their life path. I also find and describe the influence of software on the important areas of these communities such as the membership life cycle or course and nature of events.

Image Processing in Sports
Pleva, Pavel ; Hradiš, Michal (referee) ; Zemčík, Pavel (advisor)
Goal of this thesis is design and implementation of application for editing multimedia content used for entertaining fans during sport events on stadiums, which will provide easy to use and intuitive graphical user interface. The theoretical part contains description of multimedia data from the perspective of this thesis, namely statical images and video. It provides the overview of multimedia applications, ranging from low end video editors to hi end media control centers. At last the closer look into sport stadiums environment is given in perspective of used digital display devices and multimedia content.
Sound to MIDI conversion
Pleva, Pavel ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This thesis deal with possibilities of conversion simple musical signal to MIDI format. It contains brief introduction into chosen parts of MIDI standard which are important for this theme. Further there are examined characteristic attributes of sound which are needed to detect from musical signal to be written in SMF or which affects detection of useful attributes. There is given an account of algorithm for conversion implemented in Matlab.
