Information System Selection
Kornelly, Roman ; Minařík, Luděk (referee) ; Koch, Miloš (advisor)
The thesis aims to describe the selection of a new information system, which should lead to process streamlining and a boost in the number of customers at Rumburak s.r.o. The first chapter lays out the theoretical knowledge needed to tackle the task at hand. The following section analyzes the internal and external environment of the company and the implications thereof. The proposal portion contains a comparison of the available information systems and selects the best among them. It develops a schedule for the implementation of the new IS, along with identifying the benefits and economic evaluation of the entire proposal.

An Environmental Impact of Pyritic Bauxite from the Dajti Mine, Albania
Novák, Jiří Karel ; Minařík, Luděk ; Peza, Luftulla Hasan ; Melka, Karel
The accelerated chemical weathering of bauxite due to acid atmospheric deposition and breakdown of pyrite was simulated using short-termed laboratory acid leaching at 20 o C. Pyrite-bearing gibbsite-boehmitic bauxite giving rise to a number of questions concerning ecology was tested along with oxic boehmitic bauxite from the Dajti mine and that from Mali Korites (Mali Thate Mts., SE Albania). The leachte of pyrite-bearing and sulphate-producing bauxite is enriched in the following risk elements: Cd, Be, Zn, Ni, Co, and much less Cr, Cu, As, and Pb. Toxic soluble hydroxy-alumina ions may be also released into the aquatic environment, because of high concentration in output leachate (563 mg/l). In contrast, the leachates of oxic boehmitic bauxites commonly contain much lower concentrations of toxic elements with exception of Cu (Dajti mine) and Be (new occurence of Mali Korites).
