A method for the determination of ECG gate signal delays.

A simple device using a rotating radioactive source was developed to monitor the presence of a delay between the patient's R wave and the gate signal being sent to the computer. Three commercial ECG gates were tested and significant delays were found in two of them. Identical patient data evaluated using ECG gates with and without significant delays produced calculated left-ventricular ejection fractions of 0.05 and 0.64, respectively.

Internal migration in the Philippines during the 1960s.

"This paper presents a regression analysis describing some of the determinants of various types of migratory flows between and within urban and rural areas in the Philippines during the 1960s.... The individual characteristics of migrants are analysed independently from the effects of macro-economic variables, in consideration of the estimation problems raised if both were combined into a single equation model." A model is developed to allow for the estimation of the consequences of migration at places of origin and destination
