    Fusion excitation function revisited

    Full text link
    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

    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 Šasko (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.

    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 započeo je ponovni uzgoj predivog lana na području sjeverozapadne Hrvatske s krajnjom svrhom očuvanja kulturne baštine. S tim u vezi istraživana je mogućnost introdukcije stranih kultivara predivog lana u nizinsko kontinentalno područje 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: četiri češke sorte (Jitka, Texa, Merkur i Bonet) i jedna nizozemska sorta (Viola). Sve sorte sijane su u dvije gustoće (2000 i 2500 klijavih sjemenki /m2). Prema dobivenim dvogodišnjim istraživanjima agronomskih i morfoloških svojstava predivog lana na dvije lokacije utvrđeno je da postoje signifikantne razlike između istraživanih sorata i između gustoća sjetve. Interakcija između ova dva faktora nije bila signifikantna niti za jedno svojstvo. Signifikantno najveće vrijednosti za većinu agronomskih i morfoloških svojstava imala je sorta Viola. U rjeđem sklopu ostvarene su više 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

    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

    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 150°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 ml–1, rehydration time=98 s), while use of inulin resulted in the lowest yield (32.71%), polyphenol retention (28.24%), bulk density (0.25 g ml–1), and the highest rehydration time (140 s)
