THE INFLUENCE OF VARIETY AND VINTAGE ON THE CHEMICAL COMPOSITION AND SENSORY PROPERTIES OF RED WINES IN PODGORICA SUBREGION (MONTENEGRO)

This paper presents the results of investigation of the influence of variety and vintage on the chemical composition and sensory properties of Vranac, Kratosija and Cabernet Sauvignon wines in Podgorica subregion (Montenegro) in vintages 2012 and 2013. The varietal wines were produced from the grapes grown at four different localities, according to a uniform manner (traditional method) in the winery of the Biotechnical Faculty, located at the experimental farm in Podgorica, at the vineyard location of Ljeskopolje. The analysis of basic chemical parameters of wines and sensorial testing of wines were carried out. The research findings show that variety and vintage (climatic conditions) significantly affected the chemical composition of wine. The higher content of alcohol and extract was measured in 2012 vintage, while the total acid content in wine was higher in2013, as a result of frequent rainfall during the growing season, especially in August and September. The highest content of alcohol, extracts and total acids was found in Kratosija wine, then in Cabernet Sauvignon, while the lowest content was found in Vranac wine in both vintages. According to sensory properties and average testing score for the two years of research, all wines fall into the category of superior wines

Uticaj važnijih negenetskih faktora na fenotipsku varijabilnost osobina mlečnosti u populaciji crno belih goveda

Modern beef production in intensive rearing conditions imposes a need for constant improvement of production traits of individuals. Meeting the growing requirements that accompany this type of production means the provision of optimal rearing conditions, not only in terms of cattle nutrition, care and housing but also in terms of health. Milk yield, milk fat and protein are properties of primary importance in dairy cattle breeding. These properties express a pronounced variability that occurs due to a large number of factors. The paper presents the average values and phenotypic variability of major milk production traits in the black-and-white cattle population raised on the farm "PK Beograd". In the first three standard lactations the average milk yield was 7.241 kg with 3.56% fat. The impact of major non-genetic factors (farm, year, season of calving) on the expression of milk production traits was also observed. The impact of the examined factors on the variability of the production traits was highly significant (P <0.01).Savremena govedarska proizvodnja u intenzivnim uslovima odgajivanja nameće potrebu konstantnog unapređenja proizvodnih osobina jedinki. Realizacija sve većih zahteva koji prate ovu proizvodnju podrazumeva obezbeđenje optimalnih uslova gajenja, kako u pogledu ishrane, nege i smeštaja, tako i zdravstvenog stanja goveda. Prinosi mleka, mlečne masti i proteina su osobine od primarnog značaja u selekciji i oplemenjivanju mlečnih rasa goveda. Ove osobine pokazuju izraženu varijabilnost koja se javlja usled delovanja velikog broja činilaca na njihovu ispoljenost. U radu su prikazane prosečne vrednosti i fenotipska varijabilnost važnijih osobina mlečnosti u populaciji crno belih goveda gajenih na farmi PK “Beograd”. U prve tri standardne laktacije ostvaren je prosečan prinos od 7241 kg mleka sa 3,56% mlečne masti. Posmatran je i uticaj važnijih negenetskih faktora (farme, godine, sezone teljenja) na ispoljenost osobina mlečnosti. Ustanovljen je visoko značajan uticaj ispitivanih faktora na varijabilnost posmatranih proizvodnih svojstava (P< 0.01)

Rodnost i kvalitet grožđa sorte žižak u Podgoričkom vinogorju

In this paper are presented the results of two years study (2014-2015) of productivity elements and quality of grape of žižak variety in Podgorica wine region. Research was carried out in the vineyard of the Biotechnical Faculty in Podgorica, which is in full productivity phase. The results show that this variety continues to show good production characteristics, despite greater negative effect of climate changes. Environmental factors had no significant effect on the percentage of emerged and fruiting canes. A larger number of inflorescences per emerged and fruiting cane (1.20, and 1.44, respectively), grape yield and cluster weight were achieved in 2015 (1.4 kg/m2 and 156 g). In this year a higher sugar content (22.1%) was measured. Significantly higher acid content (6.8 g/l) was measured in 2014, as a result of the heavy rainfall during the growing season. These studies show that the elements of fertility and quality of grape žižak were in accordance with the weather conditions in the studied years.U radu su prikazani rezultati dvogodišnjih proučavanja (2014-2015) elemenata rodnosti i kvaliteta grožđa sorte žižak u podgoričkom vinogorju. Istraživanja su obavljena u vinogradu Biotehničkog fakulteta iz Podgorice koji je u fazi pune rodnosti. Rezultati istraživanja su pokazali da, i pored sve izrazitijeg negativnog dejstva klimatskih promjena, ova sorta i dalje pokazuje dobre proizvodne karakteristike. Ekološki faktori nisu značajno uticali na procenat izbilih i rodnih lastara. Veći broj cvasti po izbilom i rodnom lastaru ( 1,20, odnosno 1,44) , prinos grožđa, kao i masa grozda ostvareni su u 2015. godini (1,4 kg/m2, odnosno 156 g). U ovoj godini utvrđen je i veći sadržaj šećera (22,1%). Značajno veći sadržaj kiselina (6,8g/l) izmjeren je u 2014.godini, štoje posljedica obilnih padavinatokom vegetacije vinove loze. Ova istraživanja su pokazala da su elementi rodnosti i kvalitet grožđa sorte žižak bili u direktnoj saglasnosti sa meteorološkim uslovima u proučavanim godinama

Uticaj folijarne prihrane na privredno tehnološke karakteristike sorte Kardinal

The study was preformed in the vintage 2015 with the aim to exame infuluence of use foliar fertilizers to the yield and the quality of Kardinal grapes. Folowing fertilazers were used: Folifertil B11, Wuxal Super, Wuxal magnezijum, Wuxal Ferro i Slavol. Each variant included 15 vines separated in three repetitions per 5 vines. The obtained results showed that fertilization had a positive effect on both: the yield and the content of sugar and acidity. The lowest average yield had the control variant. The differences are mostly and highly significant between variant with and without fertilizers. The highest yield was at Folifertil B 11 variant where the relative difference was from 0,45 to 1,6 in compare to not- fertilization. All variants of fertilization had higher content of sugar in compare to thecontrol variant.Tokom2015. godine ispitivan je uticaj specijalnih (kompleksnih) folijarnih đubriva na visinu prinosa i kvalitet grožđa sorte Kardinal. Korišćeni su sledeći preparati: Folifertil B11, Wuxal Super, Wuxal magnezijum, Wuxal Ferro i Slavol. U svakoj varijanti bilo je po 15 čokota rasporedjenih u tri ponavljanja po 5 čokota. Postignuti rezultati ukazuju da se đubrenje pozitivno odrazilo, kako na prinos tako i na sadrzaj šećera i kisjelina u grožđanom soku. Prosječno najmanji prinos grožđa imala je kontrola a razlike su uglavnom značajne i vrlo značajne u korist varijanata đubrenja. Najveći prinos bio je kod varijante Folifertil B11 a relativna razlika je od 0,45 do 1,6 u korist varijanata đubrenja. Sve varijante đubrenja su imale veći sadržaj šećera u širi od kontrole

THE ROLE OF CANDIDA ALBICANS ON THE DEVELOPMENT OF STOMATITIS IN PATIENTS WEARING DENTURES

Denture stomatitis is the most common inflammatory reaction that occurs in people who wear dentures. It is believed that in 60-65% of cases the cause of this inflammation is infections by yeasts from the genus Candida (C.), primarily Candida albicans infection. C.albicans is a part of the normal microflora of the respiratory and digestive tract. This yeast has the ability to adhere to the oral mucosa and to the base of the denture, as well as to form a biofilm. Its virulence is especially supported by the state of weakened resistance of the organism, when C.albicans expresses its pathological effect. This paper presents the pathogenesis of C. albicans-associated denture stomatitis, as well as the most common diagnostic and therapeutic procedures used to diagnose and successful therapy

National Stereotypes in Teaching English as a Foreign Language

This thesis explores how to deal with lexically encoded national stereotypes in the second language classroom. I address this question starting with previous research on stereotypes, and discussing a principled approach to interrelating insights from a variety of paradigms and disciplines. Then I shift to the linguistic analysis of nationality words in English - phrases, idioms and proverbs, as well as connotations which these lexical items are capable of developing in certain contexts. Finally, I consider the implication of the findings for foreign language teaching, and suggest a pedagogical model for dealing with stereotypes in the language classroom

Serbia's Food Trade Competitiveness and PTAS in the EU Integration Process

The aim of the paper is to investigate Serbian food trade in the process of EU integration, particularly the effects of EU Preferential trade agreements (PTAs) and CEFTA integration on Serbian food exports. We analyse the developments in Serbian food trade flows from various aspects: the importance and growth of overall food exports and net-exports, intra-regional (with CEFTA) and extra-regional trade (with EU), as well as trade competiveness of Serbian food trade related to its most important foreign trade markets. In spite of the fact that total export from Serbia recorded decrease during the last decade, especially after the Great economic crisis, the Serbian food exports did not follow the same pattern. That points out the importance of the food trading, especially during the crisis. The food trading is the only sector that one country continuously can count on in the world trade, and the main reason for this conclusion we can find in the real nature of this sector – food sector produces goods for human diet as an existential need
