SETTING PUBLIC SERVICE PRIORITIES FOLLOWING SUCCESSFUL TAX AND SPENDING LIMITING INITIATIVES
Public Economics,
U.S. international transactions in 1999
The U.S. current account deficit increased substantially in 1999 as the balances on goods and services, investment income, and unilateral transfers all became more negative. The remarkable strength of the U.S. economy contributed significantly to a marked decrease in the balance on goods and services; to a lesser extent, previous declines in U.S. price competitiveness also played a role. The balance on investment income decreased because of the additional net income payments on the growing U.S. external indebtedness. In 2000, domestic spending may well continue to outstrip domestic production and increase the current account deficit. But adjustments that should slow the process are also at work.International trade ; Exports ; Imports

Thermomechanical effects in high-speed seal rubs
The analytical effort was aimed at development of numerical model of thermal and mechanical phenomena which occur during seal rub. Finite element programs were develped for studying the temperatures that result from frictional heating during rubs, and the plastic deformation which is caused by rub forces. The experiment phase was originally intended to aid in verification of the results of the analytical model. Experimental techniques were developed for measuring surface temperatures and deformations during single pass rubs. Modifications were made to the device to permit testing at both high and cryogenic temperatures. The results from the experiments are discussed
