Fusion excitation function revisited
We report on a comprehensive systematics of fusion-evaporation and/or
fusion-fission cross sections for a very large variety of systems over an
energy range 4-155 A.MeV. Scaled by the reaction cross sections, fusion cross
sections do not show a universal behavior valid for all systems although a high
degree of correlation is present when data are ordered by the system mass
asymmetry.For the rather light and close to mass-symmetric systems the main
characteristics of the complete and incomplete fusion excitation functions can
be precisely determined. Despite an evident lack of data above 15A.MeV for all
heavy systems the available data suggests that geometrical effects could
explain the persistence of incomplete fusion at incident energies as high as
155A.MeV.Comment: 8 pages, 5 figures, contribution to the NN2012 Proceeding
The first record of the Chinese pond mussel Sinanodonta woodiana (Lea, 1834) in Montenegro
Sinanodonta woodiana (Lea, 1834), Chinese pond mussel (Bivalvia: Unionoida:
Unionidae) is one of the most invasive aquatic macroinvertebrate species
found in Europe. We report the Chinese pond mussel for the first time in
Montenegro, in August 2012, in Lake Å asko (Adriatic part of the Central
Mediterranean subarea). One specimen of the Chinese pond mussel was observed
in a habitat with a predominantly silt-clay substrate. The main pathway of
species introduction was evaluated to be via fish stocking. [Projekat

Effects of climatic factors on grain vitreousness stability and heritability in durum wheat
Modern durum wheat breeding programs are becoming more oriented toward creation of not only high-yield cultivars but also high quality, with good stability for the trait of interest. Vitreousness of grain is associated with semolina granulation, color, and protein content; it is regarded as one of the most important characteristics in the grading industry, affecting the commercial value of the commodity. A set of 15 winter and facultative durum wheat genotypes was tested for grain vitreousness across 6 environments for 2 consecutive years. Three-way analysis of variance showed that genotype, location, and year contributed 4.1%, 20.6%, and 42.2% to the total sum of squares, respectively. Interaction terms, including genotype, contributed 6.1% to the total sum of squares, and location x year contributed 27.0%. Stability of grain vitreousness for the examined breeding lines and cultivars of durum wheat was shown by the site's regression. Broad-sense heritability of grain vitreousness was estimated to be 71%. Climatic variables were used for factorial regression modeling, and most of the interaction term for grain vitreousness was explained by mean temperatures in June (54.4%) and April (14.2%), and precipitation (14.4%) and sunshine hours (14.3%) in March. During the grain filling and grain ripening stages, the most influential climatic variables in explaining interaction were maximum temperature (43.4%), precipitation (30.9%), and sunshine hours (5.6%)

ESTIMATION OF SOME IMPORTANT AGRONOMIC AND MORPHOLOGICAL TRAITS OF FIBER FLAX VARIETIES IN DIFFERENT PLANT DENSITIES
Prije nekoliko godina zapoÄeo je ponovni uzgoj predivog lana na podruÄju sjeverozapadne Hrvatske s krajnjom svrhom oÄuvanja kulturne baÅ”tine. S tim u vezi istraživana je moguÄnost introdukcije stranih kultivara predivog lana u nizinsko kontinentalno podruÄje RH. Pokusi su postavljeni tijekom dvije godine (2002-2003) na dvije lokacije (Maksimir i Posavski Bregi). U pokusu je bilo zastupljeno pet sorata i to: Äetiri ÄeÅ”ke sorte (Jitka, Texa, Merkur i Bonet) i jedna nizozemska sorta (Viola). Sve sorte sijane su u dvije gustoÄe (2000 i 2500 klijavih sjemenki /m2).
Prema dobivenim dvogodiÅ”njim istraživanjima agronomskih i morfoloÅ”kih svojstava predivog lana na dvije lokacije utvrÄeno je da postoje signifikantne razlike izmeÄu istraživanih sorata i izmeÄu gustoÄa sjetve. Interakcija izmeÄu ova dva faktora nije bila signifikantna niti za jedno svojstvo. Signifikantno najveÄe vrijednosti za veÄinu agronomskih i morfoloÅ”kih svojstava imala je sorta Viola. U rjeÄem sklopu ostvarene su viÅ”e vrijednosti istraživanih svojstava.With the aim to preserve the cultural heritage, fiber flax culture was resumed in northwestern Croatia a few years ago. Possibilities of introducing foreign fiber flax cultivars in the lowland continental part of Croatia were investigated for this purpose. Cultivar trials were set up in two years (2002-2003) and on two locations (Maksimir and Posavski Bregi). The trials involved five cultivars: four Czech cultivars (Jitka, Texa, Merkur and Bonet) and one Dutch cultivar (Viola). All cultivars were sown in two densities (2000 and 2500 seeds/m2).
According to the results of the two-years research into the agronomic and morphological traits of fiber flax on two locations, significant differences were established between the cultivars and the planting densities under study. Interaction between these two factors was not significant for any trait. Significantly highest values for agronomic and morphological traits were recorded in the cultivar Viola. Higher values of the traits studied were obtained with the lower planting density

Glaucoma Triple Procedure: A One-site vs. a Two-site Approach
The purpose of this study is to describe and evaluate the success rate of combined
glaucoma and small cataract surgery by means of a one-site versus two-site approach.
Fifty-eight eyes of fifty-five patients undergoing combined surgery were operated: thirtyone
eyes underwent two-site approach and twenty-seven eyes underwent one-site approach.
Short term and long term mean intraocular pressure (IOP) was similar in both
groups. There was no significant difference in postoperative inflammation and complication
rates between two groups. There is no significant difference in the postoperative
results in those two different approaches to perform combined operations of cataract
and glaucoma
Microencapsulation of Olive Leaf Extract by Spray Drying
The aim of this research was to obtain a high value powder of olive leaf extract (OLE) rich in polyphenols by spray drying. Since carrier, polyphenols/carrier ratio, and inlet temperature could have an impact on process yield and polyphenol retention, to define the most promising drying conditions for OLE experiment with gallic acid model solutions (GAS) was conducted. Influence of carrier type (maltodextrin, inulin, gum arabic, and their two-component blends), polyphenols/carrier ratio, and temperature on process yield of spray dried GAS was examined, and for each carrier the most promising temperature and ratio were selected. Optimal temperature for all GAS samples was 150Ā°C, and optimal gallic acid/carrier ratio for samples with inulin or gum arabic was 3:1, while for all other combinations it was 5:1. In OLE powder produced under these conditions, polyphenol content and physical properties (rehydration, bulk density) were determined. Mixture of maltodextrin and gum arabic resulted in the highest OLE product yield (54.48%) and the highest polyphenol retention (56.50%) obtaining good physical properties (bulk density =0.31 g mlā1, rehydration time=98 s), while use of inulin resulted in the lowest yield (32.71%), polyphenol retention (28.24%), bulk density (0.25 g mlā1), and the highest rehydration time (140 s)
