Studies of Urea Excretion. Ix. Comparison of Urea Clearances Calculated from the Excretion of Urea, of Urea plus Ammonia, and of Nitrogen Determinable by Hypobromite.
According to the usually accepted concept, the urea removed from the blood by the kidneys is excreted in two forms, chiefly as urea itself, but partly as ammonia. That the ammonia of the urine is formed in the kidneys was demonstrated by Nash and Benedict (1921), in work which has been confirmed by other authors (cf. Peters and Van Slyke, I, p. 373). Evidence from animal experiments in v4vo has...
متن کاملModeling and forecasting demand for petrochemical products of Persian Gulf Petrochemical Industries Company (PGPIC)
This article models and forecasts the domestic and exports demand of products of Persian Gulf Petrochemical Industries Company (PGPIC) using a dynamic panel data model. The model is estimated using GMM method and domestic and export price index, the quantity demanded of the company's products, the global price index of alternative products and the income of demandant companies for the PGPIC'...
متن کاملDetermination of ammonia and urea in urine and of urea in blood by use of an ammonia-selective electrode.
I propose a single, quick method for measuring ammonia in urine and urea in plasma and urine. An ammonia-selective electrodie is used, set up on a microcell, which allows use of small sample volumes. Ammonia is measured directly after partial conversion of ammonium ions to NH3. Urea is measured after its hydrolysis by urease. With urine, the two procedures can be carried out successively in the...
متن کاملAn assessment of ammonia emissions from dairy facilities in Pennsylvania.
A survey of 715 Holstein dairy farms in Pennsylvania was used to construct demographics for the average Holstein dairy farm. The average Holstein dairy farm was composed of 69 lactating cows; 11 nonlactating, pregnant cows; 44 heifers; and 18 calves. Milk production averaged 27.3 kg (60.0 lb). Crop area averaged 73.6 ha. Milk production, crop area and type, average county yields, and herd anima...
متن کاملThe Comparison of Urea with Urea + Ammonia Clearances in Acidotic Dogs.
In 1921 Nash and Benedict (11) advanced the hypothesis that urinary ammonia is formed in the kidney from some precursor in the blood. This conclusion was based upon the observation that the concentration of ammonia was higher in the renal vein than in the renal artery, that the quantity of ammonia in arterial blood was too small to supply the ammonia found in the urine, and that the arterial am...
