Learning to read is one of the most important academic accomplishments in the early grades of elementary school. Knowing what factors contribute to reading ability would improve instructional practices. The goal of the present study was to examine the effects of semantic fluency, phonological fluency, rapid naming, inhibitory control, selective attention, and visual motor integration on reading fluency in 140 second and third grade students. The results of this study indicated that significant predictors of reading fluency were: selective attention, semantic fluency, inhibitory control, and rapid naming. However, the association between predictor variables and reading fluency was moderated by the students’ grade. The article concludes with some suggestions on how to improve reading fluency in elementary school children, given that all predictors are susceptible to instruction.

The paper presents a model for numerical simulation of interaction between the fluid and the reinforced-concrete structure under seismic load for spatial 3D problems, with an emphasis of concrete dams. The model is based on the so called partition scheme for coupled (multi-field) problems. The model especially focuses on the concrete ageing effects, which has proven to be highly significant in the analysis of older structures. The paper starts with a brief description of the numerical model, which is followed by a more detailed description of the concrete ageing model, and by analysis of Jablanica hydropower plant (HPP) on which the validity of the model and related software was checked.

In this work, various combinations of the NO emission influencing factors and their x combined effects in air staging combustion on level of furnace, using over fire air, were investigated in an experimental lab-scale furnace. At this, process temperature were varied in the range from 950?C to 1450?C, excess air ratio in primary zone in the range ? = 0.9 - 1.2, while distance of over fire air nozzles from the burner outlet varied until a 1 given distance of 2/5 of total length of furnace. Basic fuel is brown coal from Middle Bosnia coal basin, mixed in two coal blends and one coal-woody biomass blend, to combine an effect of fuel characteristics variation on NO emission. Results shows that x an average reduction of NO emission over tested temperature range, when using over x fire air against conventional air supply with over fire air switched off, is 26.5%. At this, much more NO emission reduction for two coal blends were occurred at higher x temperatures ? at 1350?C and above, where an average NO emission reduction is x 32.5%. Furthermore, it was found that the NO emission decreased with an increase in x distance of over fire air nozzles from the outlet level of burner until a distance of 1/3 of total furnace length; with further increase of the distance, NOx emission is stabilised and no further effect to NOx emission reduction was observed, while CO emission and unburnt increased.

Lindström – Gessel – Viennot theorem connects linear algebra and combinatorics with graph theory. We will present proof of LGV theorem and its application on Cauchy – Binnet and generalized Cauchy – Binnet formula as well as calculation of binomial determinants and some other specific determinants.

Uobičajna svrha ove intervencije je zaštita moždanog tkiva, smanjenje lokalnog bola i poboljšanje estetike kranijalnog svoda. Kranijalne proteze mogu biti napravljenje od različitih materijala: autologne kosti, titanijuma, keramike i polimera. Njihova proizvodnja je skupa i često zahtijeva kompleksne intraoperativne procese, što ponekad rezultira slabim estetskim rezultatima kod velikih i kompleksnih defekata. Ovaj rad, na konkretnom primjeru, predstavlja metod za izradu implanta po mjeri pacijenta od polimetil metakrilata, uključujući trodimenzionalnu rekonstrukciju baziranu na CT snimcima, tehnologiju 3D printanja i izradu kalupa od zubarskog gipsa.
