    Obtaining of Boron as an Alternative Fuel from Borax with Various Methods
    (TAYLOR & FRANCIS INC, 2009) Sen, N.; Demir, C.; Demirbas, A.; Kar, Y.
    This study examined how to obtain elemental boron from borax. For this purpose, first boric acid (H3BO3) was obtained from borax decahydrate with using HCl and H2SO4. The boric was then converted to boron oxide using a dehydration process. It has been studied to reduce the boric acid and the boron oxide into elemental boron with using the elemental magnesium (Mg) and butyl nitrite (C5H9NO2), and also with using sawdust, charcoal, and cellulose. Then, the obtained elemental boron was subject to the burning process to prove its purity. The pure-elemental boron gave a strong green-colored flame when it was burned. Among these, the methods using the elemental magnesium (Mg) and butyl nitrite (C5H9NO2) in order to obtain elemental boron are more reasonable than those of the others.

    Pre and Postprandial Total Serum Bile Acid Concentration Following Acute Liver Damage in Dogs
    (BLACKWELL WISSENSCHAFTS-VERLAG GMBH, 1997) Turgut, K.; Demir, C.; Ok, M.; Çiftçi, K.
    The importance of preprandial and postprandial total bile acids were investigated in dogs with liver damage induced by carbon tetrachloride (CCl4) administration. Six healthy and mature dogs were used. After base-line clinical and biochemical examinations, hepatocellular damage was induced by oral CCl4 administration. Determinations of plasma total protein (TP), albumin (Alb), total and direct bilirubin (TBil, DBil), alanine aminotransferase (ALT) and alkaline phosphatase (ALP) along with histologic ex-amination of the livers 10 days following CCl4 administration were conducted to ensure that hepatic damage was in fact induced by the CCl4 administration. Twelve h fasting preprandial and 2 h postprandial serum total bile acids (PRSBA, POSBA) concentrations were also measured. The median plasma TP, Alb, TBil and DBil concentrations did nor show any difference (P > 0.05) during the study. Plasma ALT activities increased significantly (P < 0.05, P < 0.01) between on the 3rd and 10th days of the experiment. The median serum values of PRSBA and POSBA were significantly different (P < 0.01) on the first day and continued to be different during the experiment. In conclusion, POSBA seemed to be more reliable than PRSBA in the diagnosis of hepatic necrosis.
