In-situ investigation of sucrose hydrolysis - successful link between design of experiment, RC1 and reactIR system
Katja Zajšek, Andreja Goršek, 2008, original scientific article

Abstract: The main purpose of this work was combining the modern laboratory equipment (RC1 reaction calorimeter and ReactIRTMiC10 reaction analysis system) and the concept of the Taguchi fs design of experiment to determine the relative influence of important process parameters affecting the sucrose hydrolysis. The reaction was catalyzed by strong acidic cation-exchange resin Amberlite IR-120 in H+ form. Four process parameters, including reaction temperature (.), sucrose mass concentration (fÁS), catalyst mass concentration (fÁC) and the rotational frequency of the stirrer (fm) at four levels were considered in this study. Relative contributions of the proposed influencing process parameters on hydrolysis time were estimated by analysis of the variance (ANOVA). The results showed that . had a substantial effect on the reaction time (78,3 %), the fm and fÁC had a smaller ones (7,9 % and 6,4 %, respectively), meanwhile the remain fraction to 100 % represents error (7,4 %). The optimum conditions, where the time required for complete sucrose hydrolysis would be the shortest, are: .= 79 Keywords: sucrose hydrolysis, catalyst, Taguchi method, in-situ FTIR, reaction calorimeter RC1

PROJEKT UVAJANJA CRM REŠITVE V PODJETJE
Natalija Vinšek, 2012, undergraduate thesis

Abstract: Konkurenca je vsak dan večja in podjetja iščejo različne načine kako dobiti svoje mesto na trgu. To vodi v dejstvo, da želijo podjetja v današnjih dneh vedeti vse o svojih strankah in njihovih potrebah. Če strankam ne ponudimo kaj zanimivega, bodo odšli h konkurenci. CRM rešitve so programi, ki nam omogočajo, da shranimo velike količine pridobljenih podatkov o naših strankah. Če želimo imeti CRM rešitev, jo moramo najprej uvesti v podjetje. Toda, pred tem je potrebno poznati nekaj opredelitev o sami CRM rešitvi in kako nam lahko pomaga pri našem poslovanju, posebej pri prodaji, trženju, servisu in podpori. Na žalost je veliko projektov uvedbe neuspešnih. To je zaradi prepričanja podjetja, da je dovolj, če pokličemo uvajalca in mu prepustimo delo. Vendar moramo prispevati svoj del tudi mi. Najprej moramo spremeniti poslovne procese, da bodo ustrezali novi CRM rešitvi, nato prepričati zaposlene, zakaj je nova CRM rešitev boljša. Prepričati se moramo, da je dovolj vključen tudi menedžment in so tudi oni seznanjeni s podrobnostmi uvedbe. To so le nekateri dejavniki, ki nam pomagajo k uspešni uvedbi. Za učinkovitejše uvajanje je veliko ponudnikov CRM rešitev razvilo svoje metodologije za uvajanje le-teh. Te metodologije se lahko uporabijo kot okvir za uvedbo vsake nove CRM rešitve in pomagajo zmanjšati možnost neuspešne uvedbe.

Kinetic studies of catalytic ozonation of atrazine
Brigita Tepuš, Marjana Simonič, 2008, original scientific article

Abstract: The aim of our work was to degrade atrazine by the ozone treatment of both a model and the original drinking water samples, using Pt-catalyst, and to evaluate the performance of this catalyst. The rate constant for the reaction of atrazine with ozone was determined in the model water sample. The activation energies and the reaction orders of ozone decomposition were determined in both the model and the drinking water samples. Ozone treatment using Pt-catalyst has some influence on the loss of atrazine in the sources of drinking water. The concentration of some metabolites in the model and drinking water was observed during ozone treatment. The toxicity of atrazine to crustacean Daphnia magna in the original drinking water and in the ozone treated water samples was also assessed.
Keywords: ozone, Pt-catalyst, atrazine, water treatment, waste water, kinetics
