Ponovno otkrivanje Grka – utjecaj pojačanih kontakata između zapadne Europe i Bizanta na oblikovanje humanističke misli iz perspektive Istre

The article explores the impact of Byzantines on Istrian Humanism and Renaissance. In the introduction author describes the alienation of the territories which used to be Eastern and Western part of the Roman Empire and, congruently, the fate of the classical (particularly Greek) heritage in the Dark and Middle Ages in those territories. This is followed by a description of the historical events that led to rapprochement of the East and West, with particular emphasis on the Byzantine exodus to Italy. The author then provides a methodological framework by analyzing the main aspects of „rediscovering” Greek cultural heritage and the influence of the Byzantine immigrants on them. The author than turns to Istria, providing, first, a short summary of Istrian contacts with the Greek cultural heritage throughout history and then the settlement of the Byzantines in Istria. The main part of the article follows, containing a detailed analysis of the described elements of „rediscovering” Greek cultural heritage – interest in Greek language, literature, culture and philosophy (particularly Neoplatonism), in translations, the editing and publishing of Greek classics, as well as in the presence of the idea of a common European identity based on a common ancient heritage, and the voices advocating for the formation of a united Christian European front against the Ottomans.U radu se istražuje utjecaj Bizanta na humanizam i renesansu u Istri. U uvodnom dijelu autorica opisuje otuđenje teritorija koji su nekoć bili dijelom Istočnog i Zapadnog Rimskog Carstva, kao i sudbinu klasičnoga, posebice grčkoga, nasljeđa u ranom srednjem vijeku. Slijedi opis povijesnih događaja koji su doveli do zbližavanja Istoka i Zapada s posebnim naglaskom na exodus Bizantinaca u Italiju. Autorica nadalje postavlja metodološki okvir analizirajući glavne aspekte „ponovnog otkrivanja Grka” u smislu kulturnoga nasljeđa i utjecaja bizantskih emigranata na doseljeno područje. Zatim se osvrće na prilike u Istri dajući kratak pregled istarskih kontakata s grčkim kulturnim nasljeđem kroz povijest, a zatim i pregled naselja u Istri u kojima je bilo bizantskoga stanovništva. Glavni dio rada sadrži detaljnu analizu spomenutih elemenata „ponovnog otkrivanja” grčkoga kulturnog nasljeđa s naglaskom na grčki jezik, književnost, kulturu i filozofiju (posebno neoplatonizam), na prevođenje, uređivanje i izdavanje djela grčkih klasika, kao i prisutnost ideje o zajedničkom europskom identitetu utemeljene na zajedničkoj antičkoj baštini i zalaganjima za uspostavu ujedinjene kršćanske fronte protiv Osmanskoga Carstva

Regionalization of Serbia as an instrument of balanced regional development and reduction of regional inequalities

Regionalization of Serbia in the second half of the 20th century was characterized by the dominance of the traditional approach, based on classical understanding of region as a static physiognomic spatial unit, with some attempts at economic regionalization. Such regionalizations were largely inapplicable in practice, so that they did not become part of legislative related to the planning of a balanced development of the territory of Serbia. Decentralization in socialism did not yield expected results, and after political changes in the late 20th century, Serbia became a highly centralized state. The modern concept of regionalization is relatively new in Serbia. Regional dimension of development has become the subject of scientific research in the last few decades, which is conditioned by the growing economic and demographic disparities between different parts of the state. Creating a NUTS regions in Serbia in 2009 was the first step towards modern regionalization. However, NUTS regions in Serbia do not have autonomy in regional governance and can not be able to decrease developmental disparities and support long-term economic and social development. It is therefore necessary that these territorial units get appropriate competencies in governance and decision-making, which would ensure de facto decentralization of the state and give a clear sense to the newly formed regions

Some clastic rocks as parent rocks in beech forests of Brezovica - Južni Kučaj

On the large forest areas, where the measures of soil quality improvement are absent or rarely undertaken, the rocks are the sources of a great number of elements in plant nutrition and one of the factors affecting the contents of some elements in plants. The aim of the study is to determine the differences in the contents of Cu, Zn, Mn, Ni, Fe, Cd, Co, Pb and Cr in the beech leaves developed in the same climate conditions, on morphologically similar terrains, composed of different types of sedimentary rocks. This paper presents the study results of the contents of the above elements in argillites, sandstones (grauwackes) and microconglomerates occurring as the parent rocks in high beech forests in the region of GJ Bogovina (Brezovica Južni Kučaj and in the leaves of beech developed on these rocks

Tourism climatic index in the valorisation of climate in tourist centers of Montenegro

Climate is one of the main factors for the development of recreational forms of tourism in Montenegro. It affects the temporal arrangement and spatial distribution of tourists throughout the year. It determines the context of the environment in which the activities of tourists take place and represents the tourism resources. It is important for the planning and construction of tourism facilities and infrastructure, as well as the organization of tourism activities. This paper presents the tourism climatic index as a bioclimatic indicator for determining the conditions suitable for recreational tourism throughout the year. Research results according to the case study indicate the comparative advantages and also the lack of climate as the resource in tourism of Montenegro. There is an apparent underutilization of periods with climate conditions that work in favour of recreational forms of tourism. The uneven spatial and temporal arrangement of suitable climatic conditions in the tourist centres is the factor of the formation of seasonality of tourism trends. However, the results of linear correlation of tourism climatic index and monthly visits point to the incompatibility of potentials with capacity utilization.

Indicators of regional inequality in Serbia

The diversity of spatial units of the Republic of Serbia is caused by several types of regional inequality. Only some of indicators of inequality between the regions can be considered developmental problems. In this paper indicators are distinguished by which it is possible to isolate and compare the regions of Serbia according to different criteria. This approach required use of several different methodologies from the domain of geography, economics and environmental protection. Results point to Republic of Serbia as a polarized space with a trend of concentration of population and economic activity in certain regions, and at the same time, lagging of other regions

Značaj antioksidanata u zaštiti od mikotoksikoza kod domaćih životinja

Mycotoxins are biologically active substances that are synthesized by saprophytic and parasitic fungi, and which, when taken into organism by ingestion, can provoke intoxications known as mycotoxicoses. Farm animals show different susceptibility to mycotoxins depending on various factors: genetic (species and breeds), physiological (age and obesity) and environmental (hygienic and climatic). One of the mechanisms of mycotoxin activities is peroxidation of lipids brought about directly by the production of free radicals or by increased sensitivity of tissue to peroxidation. Peroxidation of lipids provoked by mycotoxins is caused by low level of natural antioxidants, so they have a crucial role in the protection against mycotoxins. Nutritive stress can influence negatively the relationship between antioxidants/pro-oxidants, and mycotoxins are nowadays regarded as leading factors of stress induced by nutrition. This optimal relationship can be regulated by the use of antioxidants in food (selenium, vitamin E, carotenoids, etc.) known to prevent tissue damages caused by free radicals. Selenium and vitamin E are essential nutrients which contribute to the preservation of animal health by realizing mutual biological activities in the organism. This paper presents the findings on mechanisms of the action of different species of mycotoxins and the importance of antioxidative protection in farm animals, as well as the results of our investigations of influence of mycotoxins on the occurrence of some reproductive disorders in pigs.Mikotoksini su biološki aktivne materije koje sintetišu saprofitne i parazitske gljivice, a uneti ingestijom u organizam izazivaju trovanja koja se nazivaju mikotoksikoze. Domaće životinje su različito osetljive na mikotoksine zavisno od različitih faktora: genetskih (vrste i rase), fizioloških (starosti i uhranjenosti) i uslova sredine (higijenskih i klimatskih). Jedan od mehanizama delovanja mikotoksina je peroksidacija lipida direktno proizvodnjom slobodnih radikala ili povećanjem osetljivosti tkiva na peroksidaciju. Peroksidacija lipida izazvana mikotoksinima je prouzrokovana niskim nivoom prirodnih antioksidanata, tako da oni imaju ključnu ulogu u zaštiti od mikotoksina. Nutritivni stres nepovoljno utiče na odnos antioksidanta/pro-oksidanta, a mikotoksini se danas smatraju vodećim faktorima stresa izazvanih ishranom. Ovaj optimalan odnos može se regulisati upotrebom antioksidanata u hrani (selen, vitamin E, karotinoidi, i dr.) koji sprečavaju tkivna oštećenja uzrokovana slobodnim radikalima. Selen i vitamin E su esencijalni nutricijenti koji doprinose očuvanju zdravlja životinja ostvarivanjem zajedničkih bioloških aktivnosti u organizmu. U ovom radu biće prikazana saznanja o mehanizmima delovanja različitih vrsta mikotoksina i značaja antioksidativne zaštite kod domaćih životinja, kao i rezultati naših ispitivanja uticaja mikotoksina na pojavu pojedinih reproduktivnih poremećaja kod svinja

Exploração táctil da Belgrado urbana – unindo olhares femininos através do projecto wa(o)ndering women

The study attempts to discover elements of learning by practicing the right to the city through the embodiment and re-articulation of the identity of the flâneuse. In this urban investigation, we will explore perspectives that emerge from the city, how they are connected to specific city sites, and how they form our becomings, having in mind the gendered division of urban life. In order to do so, we will engage in reflexive wandering and performing in the city. Learning that unfolds with this action is a bodily and sensorial process of reading the layers of public spaces in the city. As wandering implies a turn off the main road, the learning process is marked by unpredictability and meandering. It does not follow a familiar path that leads to specific learning outcomes, but involves a journey through unknown and unowned places. We aim to describe learning that evolves by wandering around the side roads of Belgrade by mapping the experiences of the three authors. The research also involves reminiscences of the wandering of women in Belgrade that we want to re-enact and document. Este estudo procura descobrir elementos da aprendizagem, praticando o direito à cidade através da incorporação e re-articulação da identidade da flâneuse. Nesta investigação urbana exploraremos perspectivas que emergem da cidade, a forma como estas estão conectadas com lugares específicos da cidade e a maneira como formam o nosso devir tendo em mente uma divisão da vida urbana de acordo com o género. Para o fazer envolver-nos-emos em deambulações reflexivas e performativas na cidade. Uma aprendizagem que se desvenda nesta acção são os processos corpóreos e sensoriais de ler as camadas dos espaços públicos na cidade. Uma vez que a deambulação implica um desvio das ruas principais, o processo de aprendizagem torna-se marcado pela imprevisibilidade e pelo serpentear. Não segue espaços conhecidos conducentes a resultados de aprendizagem específicos, mas implica uma viagem através do desconhecido e do inapropriado. Nos interessa descrever uma aprendizagem que se desenvolve através de ruas secundárias de Belgrado através do mapeamento das experiências das três autoras. A investigação também envolve reminiscências das deambulações de mulheres em Belgrado que pretendemos recriar e documentar

Uticaj različitih nivoa organskog selena na telesnu masu, prirast, iskorišćavanje hrane i koncentraciju selena u pojedinim tkivima kod svinja

Thirty-nine gilts, 82 days old, divided into 3 groups, were fed the main diet supplemented by 0; 0.3 and 0.6 mg Se/kg in the form of Seenriched yeast during 99 days. Selenium levels of 0.3 and 0.6 mg/kg diet led to no significant bodyweight gain nor increase in body mass in any of the studied periods. However, gilts fed a diet supplemented with selenium (0.3 and 0.6 mg/kg) during the whole research period had somewhat higher body mass (1.17 and 3.36%, respectively) and higher average daily bodyweight gain (1.07 and 4.30%, respectively). Selenium supplemented diet influenced also more efficient feed conversion for 3.11 and 2.18%, respectively. The highest content of selenium was observed in the kidneys, then in liver and heart whilst the lowest selenium content was observed in the leg and neck musculature. Selenium concentration in kidneys ranged from 1.23 mg/kg to 1.38 mg/kg and no statistically significant differences were established among studied groups. Selenium concentration in the liver was 3-4 times lower, and in the heart muscle even up to 6 times lower in comparison with the kidneys. Among the studied groups statistically significant differences were established (P lt 0.01) for selenium levels in liver and heart muscle. The highest levels were observed in the group fed 0.6 mg Se/kg diet, that is, in the liver 0.511 mg/kg and in the heart 0.313 mg/kg. Selenium concentration in the leg and neck muscle was twice, i.e., three times higher in gilts fed 0.3 mg Se/kg and 0.6 mg Se/kg diet in relation to animals fed no supplemented selenium diets (P lt 0.01).Trideset i devet nazimica starih 82. dana, podeljenih u 3 grupe, hranjeno je osnovnim obrokom dopunjenim sa 0, 0,3 i 0,6 mg Se/kg u obliku seleniziranog kvasca u toku 99 dana. Nivoi selena od 0,3 i 0,6 mg/kg hrane nisu doveli do značajnog povećanja prirasta i telesne mase ni u jednom ispitivanom periodu. Međutim, nazimice hranjene obrocima sa dodatkom selena (0,3 i 0,6 mg/kg) u toku celog perioda ispitivanja imale su nešto veću telesnu masu (1,17 i 3,36%, redom) i prosečan dnevni prirast (1,07 i 4,30%, redom). Dodati selen u hranu je uticao i na efikasnije iskorišćavanje hrane za 3,11 i 2,18% redom. Najveći sadržaj selena ustanovljen je u bubrezima, a zatim u jetri i srcu, a najmanji u butnoj i vratnoj muskulaturi. Koncentracija selena u bubrezima kretala se od 1,23 do 1,38 mg/kg i nisu ustanovljene statistički značajne razlike između ispitivanih grupa. U jetri, koncentracija selena je bila 3-4 puta niža, a u srčanoj muskulaturi čak i do 6 puta niža nego u bubrezima. Između ispitivanih grupa ustanovljene su statistički značajne razlike (P lt 0,01) u nivou selena u jetri i srčanoj muskulaturi. Najviši nivo ustanovljen je u grupi hranjene sa 0,6 mg Se/kg hrane i to u jetri 0,511, a u srcu 0,313 mg/kg. Koncentracija selena u butnoj i vratnoj muskulaturi bila je dva, odnosno tri puta veća kod nazimica hranjenih sa 0,3 i 0,6 mg Se/kg hrane u odnosu na grla koja nisu dobijala dodatak selena (P lt 0,01)

Efekat gena i kombinacione sposobnosti za visinu biljke i prečnik glave kod suncokreta

Plant height and head diameter are important parameters which effect on a yield in sunflower. Six restorer Rf lines, three tester A lines and their 18 Fl hybrids were studied, using line x tester method. Significant differences were found between restorer lines and testers and their Fl hybrids for plant height and head diameter. Regarding the inheritance of examined characteristic, super dominance and dominance of better parent occurred, and the intermediary too. Tester line HA-48A (188.25 cm) and Fl hybrid HA-48A x RHA-SELEUS (245.10 cm) had the highest mean value for plant height, and the lowest value had line RHA-BRE-1 (105.35 cm) and hybrid L-19A x RHA-BRE-1 (147.9 cm). For head diameter, the highest mean value had line L-19A (19.02 cm) and Fl hybrids HA-48A x RHA-TR-20 and L-19A x RHA-TR-20 (24.55 cm), and the lowest line RHA-BRE-1 (13.10 cm) and hybrid HA-26A x RHA-M-72 (20.25 cm). Based on the results, the following conclusion is that lines RHA-BRE-1 for plant height and RHA-SELEUS for head diameter have the best GCA, and the best SCA have hybrids L-19A x RHA-BRE-1 for plant height and HA-26A x RHA-SELEUS for head diameter. Analyzing components of genetic variance, the nonadditive component played the main role in the inheritance of plant height and the additive of head diameter. The largest average contribution in the expression of plant height had the tester A-lines (83.17%) and for head diameter Rf lines had the greatest influence (58.13%).Visina biljke i prečnik glave su značajni parametri koji utiču na visinu prinosa kod suncokreta. Metodom linija x tester ispitano je šest restorer linija, tri tester A linije i njihovih 18 F1 hibrida. Utvrđene su značajne razlike između restorer linija i testera i njihovih F1 hibrida za visinu biljke i prečnik glave. U nasleđivanju ispitivanih svojstava ispoljile su se superdominacija i dominacija boljeg roditelja, ali i intermedijarnost. Najveću srednju vrednost za visinu biljke su imali tester linija HA-48 A (188,25 cm) i Fj hibrid HA-48A x RHA-SELEUS (245,1 cm), a najmanju linija RHA-BRE-1 (105,35 cm), odnosno hibrid L-19A x RHA-BRE-1 (147,9 cm). Kod prečnika glave najveću srednju vrednost su imali tester linija L-19A (19,95 cm) i F, hibridi HA-48 A x RHA-TR-20 i L-19A x RHA-TR-20 (24,55 cm), a najmanju linija RHA-BRE-1 (13,10 cm) i hibrid HA-26A x RHA-M-72 (20,25 cm). Na osnovu dobijenih rezultata može se zaključiti da najbolje OKS imaju linije RHA-BRE-1 za visinu biljke i RHA-TR-20 za prečnik glave, a najbolje PKS, hibridi L-19A x RHA-BRE-1 za visinu biljke i HA-26A x RHA-SELEUS za prečnik glave. Analiziranjem komponenti genetske varijanse, neaditivna komponenta je imala najveći uticaj na nasleđivanje visine biljke, a aditivna na prečnika glave. Najveći prosečni doprinos u ekspresiji visine biljke dale su A-tester linije 83,17%, a za prečnik glave najveći uticaj su imale restorer linije 58,13%
