Search for the biological sources of the ureide carbon atoms of uric acid has centered chiefly around compounds similar in structure to the ureide group of uric acid. One of the earliest studies on the precursors of uric acid was made by Wiener (3), who postulated that uric acid was formed by the condensation of 2 moles of urea with 1 of tartronic acid. Although this hypothesis was at first att...

We study stabilization methods for the discretization of convection-dominated elliptic convection-diffusion problems by linear finite elements. It turns out that there exist close relations between a new version of stabilization via local projection and the continuous interior penalty method.

Narasin is an antibacterial agent that may change rumen fermentation. Two experiments were proposed to evaluate the efficiency of narasin inclusion for lambs fed a diet containing high amounts ground flint corn. Thirty rumen-cannulated wethers used nutrient digestibility, nitrogen balance, and metabolism (Exp. 1); forty-five performance 2) animals with corn diets. The experimental diets were: c...

The experiment was conducted to determine the effect of nirogen levels and irrigation intervals applied with drip system on cotton yield, evapotranspiration water use efficiency in East Mediterranean Transitional Zone Agricultural Research Institute Located Kahramanmaras, Turkey during 2012 2013. In experiment, 3 different nitrogen (N0:0, N15:150, N30: 300 kg ha-1) 2 (I5: 5 I10:10 days) were in...

The efficiency of a hybrid systems method which combined artificial neural networks (ANNs) as a modeling tool and genetic algorithms (GAs) as an optimizing method for input variables used in ANN modeling was assessed. Hence, as a new technique, it was applied for the prediction and optimization of the plant hormones concentrations and combinations for in vitro proliferation of Garnem (G × N15) ...

We describe EMG responses recorded in active masseter muscles following unilateral and bilateral electrical vestibular stimulation (EVS, current pulses of 5 mA intensity, 2 ms duration, 3 Hz frequency). Averaged responses in unrectified masseter EMG induced by unilateral EVS were examined in 16 healthy subjects; effects induced by bilateral (transmastoid) stimulation were studied in 10 subjects...

Certain purines, notably adenine, are readily incorporated into the nucleic acids of rat tissues (1). Studies with glycine, a specific precursor involved in the synthesis of purines, in the same animal have shown (2, 3) relative uptakes in the ribose nucleic acid (RNA) and deoxyribose nucleic acid (DNA) fractions which are somewhat different from those obtained with adenine (4). A simultaneous ...
