The objective of research was to determine grain yield, hectoliter weight, grain proteins and starch content of 17 winter barley cultivars from trials at four locations (Tovarnik, Nova Gradiska, ...Pozega and Osijek) and during three years (2002 to 2005). All traits were significantly influenced by year (Y), location (L) and genotype (G) while sowing rate (300 and 450 seeds per m 2) and genotype*sowing rate (G*D) did not affect trait means (P>0,05). Interactions as year* sowing rate (Y*D), location*sowing rate (L*D) and year*location*sowing rate caused significant influence to grain yield and proteins and starch content in grains. Regression coefficient âbiâ, ecovalence âW i â and variance of deviations from regressions âS 2 d i â pointed out best performance of cultivars Barun, Bingo and Gvozd in more intensive growing conditions due to its top yielding, lowest proteins and rich starch content of grains. Opposite to this, best yield and quality performance of cultivars at low input production could be expected from cultivars Plaisant, Vanessa, Favorit, Lord and Heraklo.

Standard methodology for analysis of air pollution epidemiological time series was used to assess association between air pollution and mortality in elderly population of Zagreb, Croatia. During ...1995-1997 general mortality in population aged 75 and older was significantly associated with daily concentrations of nitrogen dioxide (NO/sub 2/), sulphur dioxide (SO/sub 2/) and black smoke. However, only for NO/sub 2/ the estimated curve showed significant effect within the central 90% of its range of daily concentrations. In comparison to previous results for general population, relative mortality rate for elderly was higher, supporting a hypothesis that this population is more sensitive to air pollution.
The present paper is focused on rheology dough properties of winter wheat cultivars in relation to bread crumb properties. The rheological characteristics of wheat fl our were evaluated by using ...Farinograph and Extensograph tests. The image analysis for bread crumb grain assessment was applied as alternative technique for more rapid and efficient measurement of bread characteristics. The highest significant positive correlation (P<0.05) was found between bread crumb properties and extensographic parameters: dough energy, maximum dough resistance and resistance to extensibility ratio. Cultivars ‘Klara’, ‘Barbara’, ‘Žitarka’ and ‘Golubica’ have shown finer and uniform bread crumbs with regard to optimal dough physicochemical characteristics.

Interactions as year* sowing rate (Y*D), location*sowing rate (L*D) and year*location*sowing rate caused significant influence to grain yield and proteins and starch content in grains. Regression coefficient "bi", ecovalence "Wi" and variance of deviations from regressions "S2di" pointed out best performance of cultivars Barun, Bingo and Gvozd in more intensive growing conditions due to its top yielding, lowest proteins and rich starch content of grains. Opposite to this, best yield and quality performance of cultivars at low input production could be expected from cultivars Plaisant, Vanessa, Favorit, Lord and Heraklo.
Standard methodology for analysis of air pollution epidemiological time series expresses effects in terms of relative risk, i.e. increases in the number of events associated with a short term ...increase in air pollution. However, even large relative mortality rates may in fact reflect a very small effect in terms of person-years life loss. In Zagreb, mortality in 1995–1997 was significantly associated with concentrations of nitrogen dioxide (NO2). We have used STL decomposition of time series into additive components of decreasing smoothness to test the hypothesis that mortality — air pollution association is due to short term mortality displacement. According to our results association between mortality and concentrations of NO2 remains statistically significant at time scales ranging from a few days to 1–2 months.
Studies conducted in Zagreb reported a short-term relation between air pollutant concentrations and emergency hospital visits due to the aggravation of symptoms of the chronic obstructive pulmonary ...disease (COPD). Air pollution in Zagreb is generally below the limit, and usually within the values recommended by the World Health Organization. Daily variations in the number of emergency room visits due to COPD were modeled in relation to daily variations in air pollution for the period 1995-1997. A generalized additive model for Poisson distribution was used, controlling for possible confounders, seasonality, trend, and autoregressive patterns. The effect of NO/sub 2/ was linear and significant with relative risk associated with a 50 /spl mu/gm/sup -3/ increase in NO/sub 2/ concentrations equal 1.297 (95% confidence limits 1.026-1.639). The effect of SO/sub 2/ was also linear, but not statistically significant, and that of black smoke was significantly nonlinear and of an intriguing U shape. The COPD emergency visits increased when black smoke concentrations decreased below 36 /spl mu/gm/sup -3/ (the 75th percentile) and increased above 48 /spl mu/gm/sup -3/ (the 90th percentile). This finding is attributed to possible confounding with ozone.
Bjelančevine glutena imaju ključan utjecaj na kakvoću pšenice i preradbenu vrijednost brašna. Cilj rada bio je ispitati u kojoj mjeri je omjer vlažnog glutena i ukupnih bjelančevina (WG/P), kao mjera ...dobivene količine glutena po jedinici ukupnih bjelančevina, karakteristika genotipa. U radu je analizirano 10 kultivara ozime pšenice Poljoprivrednog instituta Osijek. Kultivari se značajno razlikuju (p<0,05) po vrijednostima omjera WG/P. Kultivari S. Žitarka, Barbara, Žitarka i Golubica s omjerom WG/P između 2,7 i 3,0 pokazali su optimalna tehnološka svojstva. Gluten indeks ovih
kultivara kreatao se od 75 do 90, dok su kultivari Srpanjka, Ana i Demetra, inače poznati kao poboljšivači obzirom na vrijednost GI>90, imali omjer WG/P između 2,3 i 2,4. Statistički značajna (p<0,05) negativna korelacija (r=-0,622) utvrđena je između GI i omjera WG/P.
Analizirani su kratkoročni učinci prosječnih tjednih koncentracija NO2 u zraku na broj posjeta hitnim službama zbog pogoršanja stanja bolesti respiratornog sustava, posebno astme u odraslih i djece. ...Podaci su prikupljeni iz knjiga hitnih službi u razdoblju od 1. srpnja 1994. do 31. prosinca 1995. Bilježene su prosječne tjedne koncentracije NO2 (µg/m3), prosječne tjedne temperature (°C), tlak zraka (kPa) i relativna vlaga (%). Trend i sezonalnost procijenjeni su lokalnom ponderiranom regresijom (LOESS). Nakon isključivanja učinka trenda, sezonalnosti i meteoroloških uvjeta, broj hitnih slučajeva modeliran je u ovisnosti o tjednim koncentracijama NO2, uključujući koncentracije za tekući i prethodni tjedan te autokorelaciju reziduala. Prosječne tjedne koncentracije NO2 statistički su značajno povezane s brojem hitnih slučajeva astme u djece i odraslih s ukupnim brojem hitnih respiratornih slučajeva u djece, ali ne i u odraslih. Rezultati pokazuju da i pri umjereno visokim koncentracijama NO2 možemo opaziti učinak onečišćenja na zdravlje, pogotovo u osoba iz skupina povišenog rizika. Taj utjecaj na zdravlje osobito je naglašen u djece.
