Blood Technics for Chickens

Technics of coronary arteriography.

Thermal-dilution technics.

• .All thennal methods for the study of the circulation depend upon the induction of a change in the heat content of! the blood stream. As a result of the change, a particular time-dependent spatial distribution of temperature is developed in the blood according to the manner in which the change is brought about and as a function of the prevailing pattern of blood flow. In a general sense, any ...

Some requirements in equipment and technics for vectorcardiography.

To reduce the effects of extraneous potentials caused by muscle tremor, sweating, and interference from power circuits, it is desirable to restrict the frequency range of the cathode ray vectorcardiograph. Mathematical analysis of idealized waves and experiments with a photoelectric electrocardiographic generator indicate that a frequency range between the half-power frequency of 0.8 to 80 cycl...

Technics and Informatics in Education

Pneumatic circular manipulator is a new experimental facility developed for testing different control methods and energy efficiency of automated systems with compressed air as a working medium. Also, the manipulator has the ability of remote control, via the Internet and thereby it is an important didactic tool for teaching in the field of pneumatic control with multiple actuators. In this pape...

Isotope Technics in Clinical Cardiology.

THIS REVIEW is an attempt to answer two questions. First, are there any isotope technics available at the present time that are really useful in the care of patients? And second, what will be the role of isotope technics in clinical cardiology a few years from now? Historical Review The use of isotopes in clinical cardiology was introduced by Blumgart, Yens, and Weiss, who used radium C and a c...
