Postmodern Verbal Folklore
U diplomskom radu Äe se najprije dati teorijski pregled moguÄih definicija folklora, a nadalje bit Äe rijeÄi o razlici izmeÄu dvaju pojmova: folklora i folkloristike. Prikazat Äe se priroda veze folklorne usmene književnosti s pisanom i opisati funkcije folklora. U srediÅ”njem djelu rada bit Äe rijeÄ o suvremenom folkloru ili postmodernom folkloru i njegovim žanrovskim oblicima. Cilj ovog rada je prikazati odnos postmodernih folklornih oblika i tradicijskih oblika folklora. NajznaÄajniji žanr postmodernog folklora je urbani mit. Iznijet Äe se tematika urbanih mitova (legendi) i gradskih priÄanja aktualnih na internetu i novinama.

FISH CANNING WASTEWATER TREATMENT IN SEQUENCING BATCH REACTOR WITH ACTIVATED SLUDGE
The biological performance of flocculent sludge in sequencing batch reactor for the treatment of fish canning wastewater was evaluated in terms of organic matter and nutrient removal by gradual increase of salt concentration in the nitritation-denitritation process. Salinity negatively affected the biological system performance in a way that reduced organic and nutrient removal. The removal efficiency of organic matter and nitrogen showed good performance below 20 g NaCl/L, while phosphate accumulating organisms activity was deteriorated and declined during whole experiment. Nitrogen removal occurred as ammonium oxidation with nitrite accumulation. Nitrite reduction was not affected by salt concentration
Nitrogen Removal with Aerobic Granules ā Effect of Dissolved Oxygen and Carbon/Nitrogen Ratio
Nitrogen removal efficiency related to the dissolved oxygen (DO) concentration (DO 1ā7Ā mgĀ lā1), carbon/nitrogen ratio (COD/N 1ā14), and the effect of airflow (0.4ā2.9Ā lĀ minā1) related to the granule size were investigated. The average chemical oxygen demand (COD) removal of ā„Ā 90Ā % was achieved at COD/NĀ ā„Ā 11, but the satisfactory N values in effluent for discharge into the surface waters were almost achieved at COD/N 14. DO of 2Ā mgĀ lā1 is recommended for efficient removal of N and COD with mature granules. The size (diameter) of the granules decreases with increased airflow
Advanced oxidation treatments of olive mill wastewater
New and innovative advanced oxidative processes for wastewater treatments are currently in the focus of scientific research and development for possible industrial implantation. The main aim of this study was to investigate the effect of cold plasma treatment, high intensity ultrasound and UV radiation with the addition of additives: H2O2, TiO2, FeCl3 x 6H2O on degradation and removal of complex organic compounds from olive mill wastewater (OMWW). Olive mill wastewater represents a potential ecological problem when it is raw disposed into the environment, because of its high organic load. OMWW samples (with and without additives) were treated by high-voltage plasma discharge at frequencies 60 Hz and 120 Hz in combination with pumped gases (nitrogen, air and oxygen) for 30 minutes, by UV radiation for 30 minutes and 10 minutes by high intensity ultrasound. Physico-chemical parameters of quality, chemical oxygen demand (COD), and total dissolved carbon (TOC) were determined. The results have shown the efficacy of plasma treatment in degradation of organic compounds as well as degradation and reduction of polyphenolic compounds. Reduction of colour and total dissolved carbon occurred in all treated samples, mostly with the addition of FeCl3 x 6H2O. Treatment with UV radiation and ultrasound proved to be the most efficient resulting in the 50% reduction of organic compounds after a 10-minute treatment

Aerobni granulirani mulj u obradi otpadnih voda: mehanizam granulacije i svojstva aerobnih granula
Aerobni granulirani mulj (AGS, engl. Aerobic Granular Sludge) predstavlja obeÄavajuÄu tehnologiju u obradi otpadnih voda kuÄanstva i industrije.
Aerobne granule su samoimobilizirane mikrobne nakupine, bez nosaÄa, a karakterizira ih kompaktna gusta struktura, visoko zadržavanje biomase,
visoka uÄinkovitost uklanjanja oneÄiÅ”Äenja i svojstvo brzog taloženja. Na formiranje i stabilnost aerobnog granuliranog mulja utjeÄu brojni
Äimbenici, poput koncentracija otopljenog kisika, vrijeme prozraÄivanja, vrsta izvora ugljika, sile smicanja, period gladovanja, vrijeme taloženja.
Zbog slojevite strukture granule, sa vanjskim aerobnim slojem i anoksiÄnim i anaerobnim zonama prema srediÅ”tu granule, moguÄe je istovremeno
uklanjanje C, N i P. AGS tehnologija ima potencijal smanjenja infrastrukture i operativnih troÅ”kova proÄiÅ”Äavanja otpadnih voda. Ovaj rad daje
pregled najnovijih spoznaja iz literature o mehanizmu granulacije i svojstvima aerobnih granula

XenobioticsāDivision and Methods of Detection: A Review
Xenobiotics are compounds of synthetic origin, usually used for domestic, agricultural, and industrial purposes; in the environment, they are present in micropollutant concentrations and high concentrations (using ng/L to Āµg/L units). Xenobiotics can be categorized according to different criteria, including their nature, uses, physical state, and pathophysiological effects. Their impacts on humans and the environment are non-negligible. Prolonged exposure to even low concentrations may have toxic, mutagenic, or teratogenic effects. Wastewater treatment plants that are ineffective at minimizing the release of xenobiotic compounds are one of the main sources of xenobiotics in the environment (e.g., xenobiotic compounds reach the environment, affecting both humans and animals). In order to minimize the negative impacts, various laws and regulations have been adopted in the EU and across the globe, with an emphasis on xenobiotics removal from the environment, in a way that is economically, environmentally, and socially acceptable, and will not result in their accumulation, or creation of compounds that are more harmful. Detection methods allow detecting even small concentrations of xenobiotics in samples, but the problem is the diversity and mix of compounds present in the environment, in which it is not known what their effects are). In this review, the division of xenobiotics and their detection methods will be presented
