    The Conversion of Low-rank Kilyos Coal to Nitrogeneous Fertilizers
    Hakli, Ö; Dumanli, AG; Nalbant, A; Okyay, F; Yürüm, Y
    The aim of this work is to convert the low-rank Kilyos coal to a material that could be used as a nitrogenous fertilizer. Incorporation of nitrogen into this Kilyos coal was accomplished by oxidative ammoniation, which was a two-step process involving oxidation with nitric acid followed by a treatment by ammonia. The nitrogen content of the raw coal increased from 0.8% to 8.3-9.3% after ammoniation process. Trace element concentrations in the nitro-coal, humic acid, and oxy-ammoniated coal samples were within the acceptable ranges to be used as nitrogenous fertilizer. Therefore the oxy-ammoniated products could be considered as high-value fertilizers.

    Functional Reach and Lateral Reach Tests in Turkish Children
    Yuksel, E; Kahraman, BO; Nalbant, A; Kocak, UZ; Unver, B
    Aims: The functional reach test (FRT) and lateral reach test (LRT) provide important measures of postural stability. The aims of this study were to (1) establish the normative values for FRT and LRT, and (2) examine the effects of age, gender, and various anthropometric measurements on FRT and LRT. Methods: Two hundred eighty children, aged 6-12 years, completed the study. One hundred fifty-two subjects were females. The mean age was 9.0 +/- 2.0 years. Each child performed two trials of FRT and LRT. Results: No significant differences were detected in any age group between males and females. The normal values of FRT ranged between 23.0 and 36.5 cm, and that of LRT between 18.0 and 28.0 cm. Height, length of upper and lower extremity, and arm span had a higher correlation with FRT. Age and weight showed a good correlation with FRT. Age, height, weight, length of upper and lower extremity, and arm span showed good correlation with LRT. Conclusions: These normative data will be useful for clinicians in the assessment of balance of individual children and in the diagnosis of potential balance deficits at an early age in the Turkish population.
