- 4 - Abstract The aim of this study was to carry out phytoextraction experiments using corn plants (Zea mays) and determine the phytoextraction efficiency for specific non-steroidal anti- inflammatory drugs and carbamazepine and their combinations. After 10 days of growth, a nutrient solution containing ibuprofene, naproxene, diclofenac and carbamazepine in concentrations ranging from 5 to 10 mg/L was added to hydrophonically cultivated plants. Nutrient solution samples were taken every 24 hours and the samples were then analysed using a HPLC/DAD system. At the end of the experiment, the experimental plants and roots were analysed for extractable residua using HPLC/DAD + FLD. The greatest phytoextraction efficiency was found for ibuprofene. The second and third most effective extraction was observed for naproxene and diclofenac, depending on the evaluation criteria. The lowest phytoextraction efficiency was observed for carbamazepine. With multi-component experiments, lower phytoextraction efficiency was found out for all substances with the exception of ibuprofene in combination with diclofenac and carbamazepine. The toxic impact of ibuprofene on plant transport mechanisms was also proven. The extractable residua analysis confirmed the ibuprofene's toxicity on plant transport mechanisms and also the...

The diploma thesis is dealing with the valuation of the Compaq FARMAK, a.s. and it is created for potential investors. The company evaluation refers to December 4, 2013. The beginning of the thesis is related to the theoretical part, where methods used in the practical part are described. In the first instance, there is financial analysis of financial statements performed. The analysis has three elements -- vertical analysis, horizontal analysis and ratio analysis. Then the strategic analysis is performed with its analysis of micro and macro environment. Then financial plan was planned based on previous analyses and prognosis of value generators. The valuation of the company is using yield method of discounted free cash flow. -- FCFF and then the value is compared with the accounting value of the company.
