Abstract:
The thesis is about the topic of rebranding on a concrete case from the Czech Republic. The main goal of this thesis is to find a strategy for the rebranding campaign of the Garnier Naturals brand. The key benefits of the paper are the summarization of the rebranding process in general as well as concrete process for the Garnier Naturals brand. In the theoretical part of the paper is the theory behind brands and case studies about both successful and unsuccessful rebranding. In the application part there is an image study of the original brad as well as an analysis of quantitative research and

Abstract:
Independent determination of the heat capacity of the sapphirine used in this study is currently underway. It is expected that extrapolation of this data to the results of this study will result in the derivation of a heat capacity function for natural sapphirine from 0-1573K. Incorporation of this into existing thermodynamic datasets should allow the quantitative determination of the position of sapphirine-bearing reactions in petrogenetic grids relevant to ultra-high temperature metamorphism in natural systems.

This difference in data rates can mainly be explained by the limited allowed frequency spectrum, the nature of the radio signal and the high requirements imposed on all hardware designed for high speed and wideband wireless communications. However, the demand on wireless commercial applications at competitive costs is growing. The first step in

Abstract Mercury is a global pollutant that accumulates easily in forest soils, even in remote areas. Mercury accumulated in soils can be subsequently released into surface waters causing an increased eco-toxicological and human health risk. The most toxic form of mercury to humans and wildlife is methyl mercury (MeHg), which can be formed in the environment via methylation processes. In freshwaters, MeHg is readily accumulated in fish, which are the main source of human exposure to MeHg.
