ELEKTRONSKO UPRAVLJANJE DOKUMENTOV V PROCESIH Z UPORABO ODPRTOKODNIH REŠITEV
Lejla Gušmirović, 2012, master's thesis

Abstract: V današnjem času je na voljo je ogromno poslovnih rešitev, od splošnih do specifičnih, od poceni do dragih, in je težko izbrati najbolj primerno, saj nihče ne more zagotoviti, ali bo izbrana rešitev dejansko najbolj primerna v določenem okolju. Uspeh uvedbe poslovnih rešitev je odvisen od veliko dejavnikov in je sestavljen iz množice aktivnosti, ki morajo biti izvedene v pravem trenutku na pravilen način. Komercialne rešitve lahko predstavljajo visok finančni zalogaj, saj imajo time ljudi, podporo in veliko primerov dobre prakse, kar končnim uporabnikom v fazi uvedbe zagotavlja visoko mero zanesljivosti in prenos odgovornosti na izvajalca. Na drugi strani pa so na voljo brezplačne, odprtokodne rešitve, ki so tehnično in tehnološko še bolj razvite in varne, saj jih razvija številčna odprtokodna skupnost po celem svetu. Vendar te večinoma nimajo uradne podpore in za uvedbo le teh potrebujemo kar nekaj znanja. V svoji magistrski nalogi sem želela na konkretnem primeru upravljanja dokumentov v procesih predstaviti možnost implementacije le teh z uporabo odprtokodnih poslovnih rešitev. Upravljanje dokumentov v procesih je v današnjem času eno pomembnejših področij informatizacije in je vsekakor trend. Zaradi kompleksnosti področja uvedbe pri uvedbi sistemov za upravljanje z dokumenti govorimo o stroškovno in časovno zahtevnih projektih, zato je izbira ustrezne rešitve še toliko bolj pomembna. Posledice nepravilne izbire rešitve in partnerja pri uvedbi so lahko za organizacijo katastrofalne. Zato sem želela v svoji nalogi podrobneje predstaviti možnost uvedbe odprtokodnih rešitev za upravljanje z dokumenti, konkretneje na primeru prejetih dokumentov, prednosti tovrstnih rešitev in tudi morebitne pasti. Ne glede na dejstvo, da je odprta koda najbolj domača na področju operacijskih sistemov in infrastrukture, je področje poslovnih informacijskih rešitev vsekakor področje, kjer so se in se še bodo odprtokodne rešitve pokazale kot primerne za uporabo v produkcijskih, poslovnih okoljih.

Particle formation using supercritical fluids
Željko Knez, 2006, review article

Abstract: Particle formation and the design of solid particles and powdery composites with unique properties is at the moment one of major the developments of supercritical fluid (synonyms: dense gases, dense fluids, high pressure) applications. Conventional well-known processes for the particle-size redistribution of solid materials are crushing and grinding (which for some compounds are carried out at cryogenic temperatures), air micronization, sublimation, and recrystallization from solution. There are several problems associated with the above-mentioned processes. Some substances are unstable under conventional milling conditions, in recrysfallization processes the product is contaminated with solvent and waste solvent streams are produced. The application of supercritical fluids may overcome the drawbacks of conventional processes, and powders and composites with special characteristics can be produced. Several processes for the formation and design of solid particles using dense gases have been studied intensively. The unique thermodynamic and fluid-dynamic properties of supercritical fluids can also be used for the impregnation of solid particles, for the formation of solid powderous emulsions, particle coatings, e.g. for the formation of solids with unique properties for use in different applications. This review will focus on the fundamentals and on recent advances of particle formation and design processes using supercritical fluids on their applications and the technological advantages and disadvantages of various processes.

Isolation of chlorophylls from stinging nettle (Urtica dioica L.)
Maša Hojnik Niderl, Mojca Škerget, Željko Knez, 2007, original scientific article

Abstract: This study was aimed to assess the feasibility of extracting chlorophylls fromstinging nettle (Urtica dioica L.) by solvent extraction. In preliminary, the investigation concerned three parts of raw material (leaves, stalk and whole plant), different preservation techniques (blanching and drying) and different storage temperatures of preserved material ( |20 C for blanched and 4 C for dried sample). Extracts were analysed for chlorophyll A and chlorophyll B, respectively, by means of HPLC method. Afterwards, optimizationof single-step conventional extraction was carried out by examining the influence of the following process parameters on the extraction yield and isolation efficiency of chlorophylls: type of organic solvent, content of water in ethanol/water mixtures, ratio solvent/material, temperature, time of extraction and pH of the extraction mixture. Furthermore,to improve the yield and/or the selectivity of the extraction, multi-step conventional extraction experiments as well as other solid ]liquid extraction techniques (soxhlet and ultra-sound assisted) were performed and compared. c 2007 Elsevier B.V.

Local search engine with global content based on domain specific knowledge
Sandi Pohorec, Mateja Verlič, Milan Zorman, 2009, original scientific article

Abstract: In the growing need for information we have come to rely on search engines. The use of large scale search engines, such as Google, is as common as surfingthe World Wide Web. We are impressed with the capabilities of these search engines but still there is a need for improvment. A common problem withsearching is the ambiguity of words. Their meaning often depends on the context in which they are used or varies across specific domains. To resolve this we propose a domain specific search engine that is globally oriented. We intend to provide content classification according to the target domain concepts, access to privileged information, personalization and custom rankingfunctions. Domain specific concepts have been formalized in the form ofontology. The paper describes our approach to a centralized search service for domain specific content. The approach uses automated indexing for various content sources that can be found in the form of a relational database, we! b service, web portal or page, various document formats and other structured or unstructured data. The gathered data is tagged with various approaches and classified against the domain classification. The indexed data is accessible through a highly optimized and personalized search service.
Keywords: information search, personalization, indexes, crawling, domain specific crawling, natural language processing, content tagging, distributed data sources, ranking functions

Relationship between the undrained shear strength, water content, and mineralogical properties of fine-grained soils
Ludvik Trauner, Bojana Dolinar, Miha Mišič, 2005, original scientific article

Abstract: The relationship between the undrained shear strength of fine-grained soils and the water content can be described with a nonlinear function in which the type of soil is determined by two parameters. It is well known that these parameters depend mainly on the mineral compositions of soilsč these relationships, however, have not yet been investigated. The findings describedin this paper define those mineralogical properties of soils which determine the values of both parameters. Experimentally obtained results suggest that the parameters primarily depend on the size of the clay minerals,their quantity in soil composition, and the interlayer water quantityin the expanding clay minerals. As this dependence is well defined, the parameters, and thus the undrained shear strength at different water content, can be defined from knowledge of these mineralogical soil properties.
Keywords: soil mechanics, clays, fine-grained soils, shear strength, water content, mineralogy

Phenols, proanthocyanidins, flavones and flavonols in some plant materials and their antioxidant activities
Mojca Škerget, Petra Kotnik, Majda Hadolin Kolar, Andreja Rižner Hraš, Marjana Simonič, Željko Knez, 2005, original scientific article

Abstract: Methanol extracts prepared from five plant materials native to the Mediterranean area, namely olive tree (Olea europaea) leaf, St. John's wort (Hypericum perforatum), hawthorn (Crataegus laevigata), oregano (Origanum vulgare) and laurel leaf (Lauris nobilis), were examined for their phenolic components. Total phenolic content was determined by the Folin-Ciocalteu method. The content of proanthocyanidins in acid-hydrolysed extracts was determined spectrophotometrically. The contents of free flavones (apigenin andluteolin) and flavonols (kaempferol, myricetin and quercetin) were determined by HPLC analysis. The time of hydrolysis of flavones, flavonols andproanthocyanidins was optimised. Antioxidant activities of apigenin, luteolin, kaempferol, myricetin, quercetin and of plant extracts were examined. Antioxidative activities were studied in sunflower oil at 98 °C, by measuring peroxide value, and in an aqueous emulsion system of -carotene and linoleic acid by measuring the absorbance of the sample. Among flavones and flavonols investigated, only myricetin inhibited oxidation of sunflower oil. All other flavones and flavonols showed pro-oxidative activity. Oppositely, in the emulsion system, only apigenin showed pro-oxidative activity while otherflavones and flavonols and plant extracts inhibited oxidation of -carotene.
Keywords: chemical processing, extraction, plant material, fenolic content, hidrolysis, antioxidants, flavones, flavonols, proanthocyanidines, oils, emulsions

Stability of proteinase from Carica papaya latex in dense gases
Maja Leitgeb, Mateja Primožič, Željko Knez, 2005, original scientific article

Abstract: Proteinase from Carica papaya latex was tested on its thermal stability at atmospheric pressure and in supercritical carbon dioxide, near-critical propane and dimethyl-ether. In supercritical carbon dioxide at 300 bar thermalactivation of the examined proteinase was improved in the comparison toatmospheric pressure. In propane and dimethyl-ether (300 bar) activity of the examined proteinase decreased. Influence of compressionžexpansion cycles on residual activity of the same proteinase in supercritical carbon dioxide (300 bar and 50 °C) was studied, as well. Different ways of transition from supercritical to low-pressure-state were used which affected residual activityof the proteinase.Addition of water in the system increased activity of proteinase from C. papaya, which was incubated in supercritical carbon dioxide for 24 h. Optimum amount of water was found to be between 0.5 and 0.7 g/L.

The Analysis of the Berlitz Approach to English Language Teaching
Admira Halvadžić, 2013, undergraduate thesis

Abstract: This paper investigates the role of the Berlitz method of teaching English in today's language education. The Berlitz method has been present in the English language area for a long time and the principal objective of this diploma thesis was to prove that even today, it is a very successful and effective method of teaching English, whose characteristics should be implemented in language classrooms around the world. The first part of my thesis introduces the history of English language teaching and the history of the Berlitz method. Characteristics of the Berlitz method, its development and the role in today's education are presented. The second part, which is also the principal part of the thesis, draws upon lesson observations of three children’s and two adult classes which I did at the Berlitz language centre in Maribor. The data collected here focused on three aspects of the didactical triangle: the teacher, the learner and the content. Important information about each segment is introduced, with the emphasis on the content, the use of teaching aids, the role of fluency and accuracy, the rapport between teachers and learners and about motivation in Berlitz classes. The last part of my thesis involves information about Berlitz kids’ camps and a survey which reveals some significant information about the teachers’ and learners’ experiences and views on the Berlitz method.
Keywords: English language teaching, the Berlitz method, lesson observations, the content, teaching aids, fluency and accuracy, rapport, motivation, Berlitz kids' camps.
