Notes: Whole triticale kernels were extruded using a Brabender Plasti-corder extruder with 3/4-in. rifled barrel and 1:1 flight depth ratio screw. Samples were extruded at initial moisture contents of 15% and 20% using barrel temperatures of 350 °F, 400 °F and 450 °F through nozzle openings of 1/8 in. and 1/16 in. The products were measured for pH, final moisture content, color, trypsin hydrolysis, torque during extrusion, and texture and flavor as evaluated by a taste panel. From the results it was concluded that an acceptable product could be produced at 20% initial moisture using either the small nozzle and operating at 350 °F or the larger nozzle and operating at 400 °F.

Notes: Abstract A totally self-contained instrument for the measurement of cardiac output is described. The microcomputer controlled instrument is based upon the principles of thermodilution and is capable of making cardiac output determinations on a minute by minute basis. A bolus of heat is delivered to the blood via a resistive heating element wound on the surface of a conventional thermodilution catheter, and the resulting transient pulmonary artery blood temperature increase is monitored with the thermistor located near the tip of the catheter. The performance of the instrument was tested in a mock circulatory loop and in dogs for periods of up to 13 hours. The accuracy and reproducibility of flow determinations made with the system compare favorably with those made with a conventional cardiac output monitor. This study demonstrates the feasibility of a stand-alone cardiac output computer that can provide virtually continuous measurements of blood flow without the intervention of a technician.
