ACCREDITATION OF LANGUAGE/LITERATURE/CULTURE CURRICULA AT THE FACULTY OF PHILOLOGY IN SERBIA

Although the Faculty of Philology – as one of 31 faculties at the University of Belgrade – is the oldest and the largest faculty of philology in Serbia (it was founded in 1908, and currently has some 350 teachers and 8,500 students), as well as one of the oldest and largest in the Balkans, its lengthy and successful tradition did not prevent the complete transformation of curricula in order to adapt them to the demands of the 21st century. The new, reformed programme of academic study has been implemented in line with the principles of the Bologna Declaration and contains elements of an integrated and transcultural approach to teaching foreign languages in higher education, together with the relevant literature and culture courses at bachelor, master and doctorate levels in over thirty departments of Belgrade Faculty of Philology. The purpose of this paper is to analyze the process of accreditation of the new programme and the outcomes of introducing the revised curricula at our academic institution, in order to highlight the success and benefits of the transformed academic courses, primarily for students but also for the staff

Security as a factor of competitive advantage in tourism

Security and protection demands in tourism industry are very high due to the vulnerability of its infrastructure in light of security challenges and threats. Actual threats appear in the form of endangering the values that compose a train of products and services in tourism – from the moment of buying/selling a package tour, transfer of passengers and luggage to their destination, to stay in hotels and meeting different needs of tourists. This work addresses the criminal, terrorist, and economic threats to hotels. The effects of these and other threats may endanger the foreign investments in tourism industry and the arrival of foreign tourists who, as the newest polls show, prioritize security factor in their selection of tourist destination. The hotel security issue is addressed in light of its preference when selecting tourism supply and services, which is an important indication of competitive advantage

TECHNOLOGICAL CHARACTERISTICS OF SOME NEW PROKUPAC CLONES

The research carried out in experimental vineyard-collection at Faculty of Agriculture experimental field Radmilovac, which is located at GPS coordinates N 44º 45' 21" and E 20º 34' 53". Experimental vineyard is located at southeast part of Belgrade, at an altitude of 130 m and covers southern exposure. It belongs to Šumadijsko-velikomoravski vineyard area, Belgrade sub-region and Grocka vineyard region. Rows were extending in southeast-northwest direction with line spacing of 3 m and 1 m between vines in row. In experiment tested clones were under codes 40/2, 42/1, 43/1 and 43/3. From technological characteristics in paper is presented data related to weight of biomas discarded in pruning, yield, mechanical composition of berries and cluster, structural indicators of berries and bunches and qualitative parameters-sugar and acid content. The biggest mass of pruning shoots was determiner at clone 40/2 (1.008 kg/vine). The highest yield is recorded at clone 42/1 (7.1 kg/grapevine) and the smallest for clone 43/1 (3.6 kg/vine). Maximum cluster mass was recorded at clone 43/1 (276 g), whereas for clone 40/2 was determined the largest weight of berries meat (254 g) and the biggest seeds number per 100 berries (208). Clones 42/1 and 43/1 are characterized with the highest recorded skin weight of 100 berries (10 and 23 g/100 berry). Same trend was recorded for percent of stem, skin and seed in cluster. Clone 42/1 had the lowest percent of meat in berry (88.21%). According to sugar content were founded the highest level for clones 42/1 (24.1%) and 40/2 (22.4%). Same trend of variation is determined for acid content in grape juice

Improved Composite Q-Function Approximation and its Application in ASEP of Digital Modulations over Fading Channels

In this paper, capitalizing on Mils ratio for Qfunction approximation, we have presented novel improved composite Q-function approximation. Based on our improved approximation, we have further presented tight approximation for the average symbol error probability (ASEP) expressions of digital modulations over Nakagami-m fading channels. First, comparison to other known Q-function closed-form approximations has been performed, and it has been shown that accuracy improvement has been achieved in the observed range of values. Further, it has been shown that by using proposed approximation, values of average symbol error probability (ASEP) for some applied modulation formats could be efficiently and accurately evaluated when transmission over Nakagami-m fading channels is observed. Also, it has been shown in the paper that by using proposed approximation, observed ASEP measures are bounded more closely, than by using other known Q-function closed-form approximations

Examination of Electron Transfer Mechanism of Cyanidin

Cyanidin, as one important plant pigment, was theoretically (at M05-2X/6-311+G(d,p) level of theory) investigated for its ability to scavenge potentially, highly damaging hydroxyl radical. Free radical scavenging of cyanidin was studied through electron transfer mechanism – ET (the second step in SPLET mechanism) in water and ethanol, as solvents. Examination was performed using density functional theory (DFT) and Marcus theory. Based on the thermochemical and kinetic data, it is clear that O‒H group of cyanidin in position 3` is the most suitable for reaction with hydroxyl radical through mentioned antioxidant mechanism

Uporedna analiza proizvodnje različitih nasadnih kategorija šarana u poluintenzivnom sistemu gajenja

Šaran (Cyprinus carpio) je kao slatkovodna vrsta široko zastupljena kada je u pitanju farmsko gajenje riba u centralnoj i istočnoj Evropi. Na području Srbije, “klasična” poluintenzivna proizvodnja je dominantan tip gajenja riba, sa preko 95% ukupno proizvedenog šarana, a zasnovana je na kombinaciji prirodne i dodatne hrane (žitarica i smeša koncentrata). Kada je reč o gajenju različitih kategorija šarana u okviru jednog proizvodnog objekta, uglavnom se pristupa gajenju samo jedne kategorije. Razlog tome su jednostavniji i manji manipulativni procesi prilikom izlova kao i sama ishrana riba, naročito kad su u pitanju žitarice i ručno hranjenje. Cilj ovog istraživanja je bio da se analiziraju mogućnosti gajenja mešanog nasada različitih kategorija šarana u odnosu na gajenje samo jedne kategorije. Eksperiment je realizovan na proizvodnom ribnjaku OZZ “Despotovo“ iz Despotova. U toku jedne proizvodne sezone, na ribnjačkim površinama A, B i C, analiziran je uticaj kombinovanog i nezavisnog gajenja dvogodišnjeg (S1+) i konzumnog šarana (S2+) na proizvodne karakteristike u poluintenzivnom sistemu gajenja, upotrebom peletirane hrane. Na osnovu dobijenih podataka o masi riba i količine potrošene hrane, dobijeni su rezultati ostvarenog prirasta (BWG) i koeficijenta konverzije hrane (FCR). Gajenjem jedne kategorije šarana ostvaren je bolji BWG nego kombinovanim gajenjem dve uzrasne kategorije riba u okviru istog proizvodnog objekta. Rezultati ostvarenog prirasta pokazali su razlike između jezera (A = 2 287 kg/ha; B = 1 399 kg/ha; C = 988 kg/ha). Razlog tome je potencijal prirasta nasađenih kategorija riba, jer se kod S1+ ostvaruje oko 3 puta veći prirast nego pri gajenju starije kategorije (S2+). FCR je takođe bio najniži pri gajenju samo S1+ (2.26). Pri kombinovanom gajenju S1+ i S2+ vrednost FCR bila viša (2.41) nego u jezeru A, ali i znatno niža nego pri gajenju S2+ u jezeru C (3.2). Korišćenje peletirane hrane sa višim sadržajem proteina (35/7), dodatno je uticalo na postizanje boljih rezultata kod S1+ gajene u jezeru A, nego kod S1+ i S2+ gajene u jezerima B i C. Ovo potvrđuju i drugi istraživači, koji ukazuju da je prirast riba bolji ukoliko je riba hranjena smešom sa većim sadržajem proteina, posebno onih životinjskog porekla. Razlike u FCR-u se pripisuju bržem metabolizmu koji je prisutan kod mlađih kategorija riba. Na osnovu vrednosti ostvarenog prirasta riba, gajenjem samo S1+ (A = 2 287 kg/ha) ili S2+ (C = 988 kg/ha), postiže se za 10% niža vrednost nego pri kombinovanom gajenju S1+ i S2+ (B = 1 399 kg/ha). Razlog tome je što mlađe kategorije riba (usled zbijenijih branhiospina) bolje iskorišćavaju sitnije organizme koji čine prirodnu hranu, kao i sitnije frakcije dodatne hrane koja se brže raspada u vodi kada se u ishrani riba koristi peletirana hrana. Moglo bi se zaključiti da se bolji rezultati BWG i FCR ostvaruju ukoliko se gaji samo jedna kategorija riba. Međutim, na osnovu preračunatog odnosa u nasadu S1+ i S2+ (20 : 80) u okviru istog jezera i ostvarenog prirasta (kg/ha) u individualnom gajenju, može se zaključiti da je prirast viši za oko 10% pri gajenju mešanog nasada S1+ i S2+

Histologija jetre i variranje površine jedara hepatocita pastrmke gajene u kaveznom sistemu

U hidroakumulacionom jezeru ”Bočac” gajena je kalifornijska pastrmka (Oncorhynchus mykiss, Walbaum, 1792) u dva odvojena eksperimenta u trajanju od po 90 dana – jedan u periodu jesen – zima, a drugi u periodu proleće – leto. Pastrmke su hranjene sa šest različitih komercijalnih hraniva i ispitivan je njihov uticaj na histološku gradju jetre riba. U eksperimentu je preovladavala normalna histološka građa jetre, a malobrojne histopatološke promene koje su uočene se mogu pripisati periodu godine i sastavu hrane. Kvantifikacija rezultata je pokazala da se sa rastom temperature vode i količine hrane kojom su ribe hranjene, prosečna površina jedara hepatocita povećava, dok se sa opadanjem temperature i količine hrane prosečna površina jedara hepatocita povećava, nezavisno od tipa hrane koja je korišćena

CHEMICAL COMPOSITION OF GRAPES AND WINE OF SMEDEREVKA VARIETY

Examination of Smederevka cv was performed in area of Belgrade region. Analysis of grapes and wine was performed in laboratory of Faculty of Agriculture and Chemistry University of Belgrade. The aim of research was qualitative and quantitative determination of aromatic compounds in grapes and wine. Aromatic compounds in grapes and wine were detected by SPME GC/MS method. Presence  of main herbaceous aromatic grape compounds as aldehydes, primarily n-hexanals and (E)-2-hexenals was detected. Terpenes (linalool, geraniol, α-terpineol), higher alcohols (isoamyl alcohol, 1-hexanol, 1-octen-3-ol, etc.), and ketones were also detected. In wine was determined presence of: esters, higher alcohols, terpenes, aldehydes, acids and ketones. Most of detected compounds belong to esters (ethyl acetate, ethyl butanoate, isoamyl acetate, ethyl octanoate, ethyl 9-octanoate, 2-methylbutyl octanoate, ethyl palmitate, etc.) which form fruit aromas (apple, banana, pear, almond, pineapple)
