The independent atomic time scale at the National Bureau of Standards AT(NBS), is based upon an ensemble of continuously operating cesium clocks calibrated occasionally by an NBS primary frequency standard. The data of frequency calibrations and interclock comparisons are statistically processed to prov...
[20]. These children were measured every three months. Majority of these infants were fed artificial milk. The limitation of NCHS was that the measurement was not adequate to describe the rapid and changing rate of growth in early infancy. Additionally, there were shortcomings inherent ...
Meanwhile, it promoted partisanship over the measurement adoption. Republicans adopted a more aggressive military posture, whereas Democrats are more sensitive to information such as the consequences of war and inequality in conscription. Finally, the government revised immigration policy and tightened the ...
In this paper, we examine the impact of national governance quality on clean energy supplies in developing countries. We used a large sample of 103 developing countries over 21 years. We employ pooled ordinary least squares as the primary estimator. Additionally, we apply a Fixed Effect and the...
This is also called as net product method or value-added method. This method is used when whole national economy is considered as an aggregate of producing units. In its standard form, this method consists of three stages: 1. Measurement of gross value of domestic output in the various branc...
