New Approaches to the Measurement of Energy Expenditure in Pigs
نویسندگان
چکیده
New procedures have been developed for the continuous measurement of energy expenditure in finisher pigs. Energy expenditure is measured from oxygen consumption calculated as the product of cardiac output and the difference in blood oxygen content between arterial and mixed venous blood (Fick principle). Key features of this approach have been the use of new technology to measure cardiac output using transit-time ultrasound and fibre-optic oximetry to measure mixed venous oxygen saturation. The results are presented for the oxygen consumption of finisher pigs at raised ambient temperatures using these new procedures.

متن کاملA New Technique based on Strain Energy for Correction of Stress-strain Curve
Tensile stress-strain curve is of high importance in mechanics of materials particularly in numerical simulations of material deformations. The curve is usually obtained by experiment but is limited by necking phenomenon. Engineering stress-strain curve is converted to true stress-strain curve through simple formulas. The conversion, however, is correct up the point of necking. From this point ...
