the chemical composition, in situ  rumen degradability coefficients of dry matter (dm) and crude protein (cp), in vitro gas production and in vivo  digestibility were evaluated for olive cake (oc) silage treated (dm basis) with different additives as follows: (1) untreated oc; (2) oc, 8% molasses and 0.4% formic acid and (3) oc, 8% molasses, 0.4% formic acid and 0.5% urea. after addition of the...

Sulfur is one of the most significant impurities in coal, which reduces the quality of coal and also results in environmental pollution. This work was aimed to investigate the removal of sulfur from coal by the leaching method employing parameters expected to affect the removal rate such as acid concentration (10-30%), temperature (40-80 °C), and reaction time (40-100 min). A response surface m...

The linoleic acid hydroperoxide obtained by enzymatic peroxidation of linoleic acid was found to react with thiobarbituric acid to yield a red pigment. The optimum pH for the reaction was found to be 4.0. In the early stages of peroxidation of linoleic acid, thiobarbituric acid value, the amount of conjugated diene, oxygen consumption, and peroxide value were in parallel with one another. The d...

The thermodynamic p K value of picric acid was determined spectrophotometrically in water containing hydrochloric acid to repress the ionization. The pK value 0.33 ( i£«0 .46) was obtained from da ta a t 450 m/*. At tempts to determine the p K value by potent iometr ic t i t rat ions of picric acid and by spectrophotometric measurements of picric acid solutions in the near-saturat ion range did...
